Definitions
- high-resistance training equipment make it inherently expensive, bulky, and difficult to transport. This leaves high-resistance training consumers with the options to (a) pay recurring fees to attend gyms, (b) buy expensive equipment themselves to place in a steadfast location, or (c) reduce the resistance and alter the methods with and by which they train. Time and time again, however, science has proven that there is no substitute for high-resistance training in regards to strength improvement, muscle development, and the efficiency of caloric depletion.
- a multifunctional fitness system may provide high-resistance exercises through the distribution of weight upon a frame that pivots on the ground.
- the weight of another person and/or conventional weights can be placed on the frame at various locations to produce the desired leverage and, thus, resistance felt by the lifter.
- the frame may also have various axes upon which it can pivot and grip points, thus offering a broad range of exercises that can be conducted. Reorienting the frame to be resting on differing sides may result in additional feasible exercises.
- Optional integrated electronics may use kinematics and/or structural flexing to calculate felt resistance and provide automated instruction to the various users. The may also collapse into a compact, rollable configuration for easy transport.
- an exercise system in one general aspect, includes a frame having a multitude of linked members.
- the frame may be configured to be reoriented onto various sides thereof to provide a user with different groups of exercises for each orientation, with at least some of a first group of exercises involving the pivoting of the frame about an end.
- the first group of exercises may also involve pivoting the frame about a second end.
- the frame has three orientations in which exercises may be performed, each with its own group of exercises.
- a second group of exercises may, for example, involve pivoting the frame about a different end than the first group of exercises. Additionally, at least some of the second group of exercises may involve sliding of the frame on the ground.
- the frame may be configured to resist sliding on the ground for the first group of exercises and/or to assist sliding on the ground for at least some of the second group of exercises.
- the frame has a bottom side, a back side, and a front side, and the orientations of the frame include upright, on its back, and on its front.
- the frame may, for example, include a base, a vertical section, and a top section when in an upright orientation.
- the vertical section may be hingedly attached to the base and/or hingedly attached to the top section.
- the base may include two portions that are hinged to each other.
- the frame may be configured to support a person such that the person acts as a weight for a number of exercises. In certain implementations, the frame may be configured to support a person at multiple locations such that the resistance felt by a user is altered.
- the frame may also be configured to collapse along a single degree of freedom. In certain implementations, the frame may collapse to less than one-half of its expand volume, and in some implementations, the frame may collapse to less than one-third of its expanded volume.
- the system may also include a mechanical overload indicator coupled to the frame. Additionally, the system may include a mechanical exertion level indicator coupled to the frame.
- the system may further include integrated electronics coupled to the frame to detect strain thereon and a transmitter to wirelessly send the detected strain to a remote computing device.
- the computing device may be configured to receive the strain indications and determine an exertion level for the exercise being performed.
- the compute device may also be configured to provide exercise instructions to a user.
- the computing device may be attached to the frame.
- the system includes light emitting electronics integrated into the frame to provide instruction and safety features for the exercise being performed.
- the system may also include audio electronics integrated into the frame to provide instruction and safety features for the exercise being performed.
- an exercise system may provide a multitude of strength building exercises of varying resistance for both arms and legs without having to rely on conventional weights. Among other things, this may allow the exercise system to be used by users of varying strength and make the exercise system more portable. As another example, an exercise system may provide an indication of exerted effort (e.g., force) even if conventional weights are not being used. As an additional example, an exercise system may be collapsible into an easily storable and/or transportable configuration. Additional features will be evident to those skilled in the art in light of the following written description and figures.

- FIG. 1 illustrates an example exercise system 1 .
- system 1 allows for high-resistance exercises through the distribution of one's own body weight and/or that of another upon a frame 2 .
- frame 2 is composed of a number of hinged linkage structures that allow the frame to collapse (to be discussed in more detail below) into a volume that is less than 50% of its expanded volume and, in some cases, less than 33%.
- the linkage structures include a deadlift linkage assembly 10 , left and right sled linkage assemblies 20 a , 20 b , a dip standing linkage assembly 30 , a sled connector linkage assembly 40 , a squat linkage assembly 50 , left and right dip sled linkage assemblies 60 a , 60 b , a spanning rod assembly 70 , and left and right dip connector assemblies 80 a , 80 b.
- frame 2 has three use orientations that are yielded from rotating the frame along its edges to rest on different faces as demonstrated in FIG. 2 .
- Each of these orientations (labeled A, B, C) allow for a different group of feasible exercises to be performed by a user.
- Orientation B squat linkage assembly 50 and dip sled linkage assemblies 60 provide a base for frame 2
- dip standing linkage assembly 30 provides a vertical section for frame 2
- deadlift linkage assembly 10 provides a top section for frame 2 .
- These assemblies serve different roles in Orientation A and Orientation C.
- Orientation A provides two pivot axes 19 , 34 , on the far left and far right of the system as viewed in FIG. 2 .
- the user lifts the opposite end of the frame, lifting the leverage weight thereof.
- the weight of another person (“liftee”) or one or more weighted plates may be placed on the structure in a location yielding the desired leverage and, thus, resistance felt by the lifter.
- the resistance offered by a liftee or weight plate may be adjustable by varying the location of the frame—the further the liftee is from the pivot axis, the greater the felt resistance by the lifter.
- Orientation B is yielded from rotating the frame about pivot 34 so that it rests on the side/face of the height-adjustable bar as seen in FIG. 2 , resulting in a taller structure.
- the bar previously at shin height in Orientation A is elevated higher in Orientation B, thus allowing for variations of the following exercises:
- the bar onto which the user holds for these exercises is configured in a manner in which various grip orientations are permitted as seen in FIG. 20 .
- Orientation C is yielded from rotating the mechanism about pivot 66 in Orientation B so that the Orientation A pivots 19 , 34 are pointed upward as seen in FIG. 15 .
- pivot 66 On one end of the mechanism in Orientation C, the left side as viewed in FIG. 2 , pivot 66 allows the opposite end to be functionally lifted.
- the other linkages contacting the ground in Orientation C are angled as to allow the sliding of the mechanism in one direction (i.e., to the right in Orientation C).
- a feature of system 1 is that a liftee may be positioned at different locations on frame 2 .
- the liftee is shown as standing on an intermediate horizontal member in Orientation A.
- the liftee could be positioned on the horizontal member immediately behind the lifter, thus increasing resistance, or positioned on the horizontal member farther from the lifter, thus decreasing resistance.
- system 1 allows users of different sizes to work out with each other.
- one liftee can provide varying resistance to a lifter.
- the system allows for additional weight to be applied.
- the frame may be designed and strengthened as to allow multiple persons to distribute their weight simultaneously on the frame for greater resistance, as illustrated in FIG. 21 .
- plate mounts are also integrated to allow the use of weighted plated as the primary means of resistance, as seen in FIGS. 22 , 23 , and 24 . Weighted plates and liftee(s) can be used in conjunction if needed, as seen in FIG. 25 .
- a feature of the system 1 is its ability to be transported easily.
- the linkage system of frame 2 for example, has one degree of freedom when unlocked, allowing it to collapse into a closed/condensed configuration.
- the linkage design can collapse into the closed configuration as illustrated in FIG. 26 , to allow for transport and/or storage in confined areas. Certain implementations, however, may use different locking mechanisms or may not collapse at all.
- Step 1 To collapse frame 2 when it is fully expanded and locked, pins 84 a , 84 b are removed (Step 1 ). Then, sled linkage assemblies 20 (only one of which is viewable in FIG. 26 ) are swung outward relative to deadlift linkage assembly 10 (counterclockwise in FIG. 26 ), which causes sled connector linkage assembly 40 to pull dip sled linkage assemblies 60 , squat linkage assembly 50 , and dip connector assemblies 80 towards deadlift linkage assembly 10 (Step 2 ). Next, dip standing linkage assembly 30 is swung towards deadlift linkage assembly 10 (counterclockwise in FIG.
- Step 4 moving dip sled linkage assemblies 60 , squat linkage assembly 50 , and dip connector assemblies 80 inside deadlift linkage assembly 10 (beginning in Step 3 and ending early in Step 4 ). Then, sled linkage assemblies 20 are swung back toward deadlift linkage assembly 10 , completing the collapse (Step 4 ).
- frame 2 may be locked into place when collapsed.
- most any of the linkage members that are close to each other may be coupled (e.g., pinned) together.
- the members that were pinned in the expanded configuration may be pinned together in the collapsed configuration, Compare Step 1 with Step 4 FIG. 26 .
- wheels 17 may emerge from one side of the frame allowing it to be easily rolled, as illustrated in FIG. 27 . (The wheels are present in FIG. 1 , but are hidden by various members due to the chosen perspective.)
- a mechanical overload indicator 90 may be built into an exercise system, as illustrated in FIGS. 1 and 28 .
- Overload indicator 90 includes a cable-spring assembly 91 placed on frame 2 so that flexion thereof under loads will place the cable and spring (connected in series) under tension.
- a shroud 92 covers the spring and part of the cable in a manner such that an overload indicator 93 (e.g., a marked portion of the cable) is hidden in an unloaded condition. Under load, however, the flexion of the frame yields in the exposure of more of the cable.
- Indicator marking 93 is placed on the cable so that the maximum allowed load will result in the marking's visibility from under shroud 92 , thus indicating applied force should be reduced (see FIG. 28 ). Utilizing the same principle, incremental ticks on the cable may allow for felt resistance estimations.
- An exercise system may also have integrated electronics that allow for more functionally precise means of determining felt resistance.
- a strain gauge 94 Placed in series with the cable/spring assembly 91 in FIG. 28 , for example, is a strain gauge 94 .
- An instrumentation-driver/battery/transmitter assembly 95 gathers the strain measured by the strain gauge during the frame's flexion under load as seen in FIG. 28 .
- onboard accelerometers may gather kinematic data. Gathered information is sent via a transmitter (e.g., via Bluetooth or Zigbee) to a user's smart device (e.g., a lifter's smart phone, smart watch, or tablet) where algorithms are used to calculate the maximum strain, felt resistance, cadence, etc.
- a transmitter e.g., via Bluetooth or Zigbee
- a user's smart device e.g., a lifter's smart phone, smart watch, or tablet
- Smart devices may not only display the calculated data but store the data as well. Storing records of the conducted exercises, user's felt resistance, lifting cadences, and other available biometric data allows for a “virtual instructor” within software onboard the associated smart device to plan and guide the users' workouts through visual and auditory means, as shown in FIG. 30 .
- FIG. 29 A general layout of example elements for a load determination system architecture 200 is seen in FIG. 29 .
- the “virtual instructor” software may be onboard a computer integrated in the mechanism itself rather than utilizing a user's smart device as the software driver.
- Load determination system architecture 200 includes a subsystem 210 onboard the frame and a remote subsystem 220 .
- all or a portion of remote subsystem 220 may be onboard the frame.
- Onboard subsystem 210 includes a number of strain gauges 212 .
- Strain gauges 212 may be mounted on the same frame member and/or different frame members. If mounted on the same member, the strain gauges may measure strains in different axes.
- Controller 214 is typically an electronic logic device (e.g., a microcontroller) and is responsible for receiving the readings from the strain gauges (usually in analog form) and preparing them for further analysis (e.g., by converting them to digital form).
- the prepared data is sent via a transmitter 216 to remote subsystem 220 .
- Transmitter 216 typically works by wireless techniques (e.g., radio frequency), but could use wired techniques in certain implementations.
- Onboard subsystem 210 also includes an accelerometer 218 , which can measure the motion (e.g., acceleration) that frame 2 is subjected to. The data from accelerometer is also sent to transmitter 216 .
- accelerometer 218 can measure the motion (e.g., acceleration) that frame 2 is subjected to.
- the data from accelerometer is also sent to transmitter 216 .
- Remote subsystem 220 may be a smartphone, a tablet, or any other appropriate electronic logic device (e.g., having an electronic processor, memory, and input/output capability). Remote subsystem 220 may only be remote in the aspect that it is connected to onboard subsystem 210 through a communication link, as opposed to being at some large geographic distance from it. In some operations, remote subsystem 220 may actually be on or inside the periphery of the frame.
- Remote subsystem 220 includes a receiver 222 for receiving data from transmitter 216 .
- the data is then fed to the appropriate calculator (e.g., an electronic logic device or a piece of code operating on an electronic logic device).
- the appropriate calculator e.g., an electronic logic device or a piece of code operating on an electronic logic device.
- data from the strain gauges may be fed to a strain calculator 224 , which may determine the actual strain occurring on the system. The actual strain may be compared to the maximum allowable strain via a comparator 230 to make sure the frame is not being overtaxed.
- data from the strain gauges may be fed to a resistance calculator, which may determine how much resistance (e.g., weight) is being felt by the user.
- the amount of axial strain on a linear member is, for example, proportionally related to the force axial applied thereto.
- Kinematic data may be fed to a kinematic data calculator 228 , which may use the acceleration data from the accelerometer 218 to qualify the movement, orientation, and displacement of the mechanism.
- a virtual instructor 232 may use software algorithms to combine, compare, reconcile, and analyze the incoming data (from 224 , 240 , 226 , 228 , 236 , 238 , and/or 240 ) to determine real-time instructions to optimize use of the system. Based on the analyzed data, the virtual instructor 232 may provide those determined instructions to the lifter (e.g., increase repetitions, decrease repetitions, reposition liftee, add weight plates, alter cadence, etc.). The instructions may be communicated via a user interface 234 , which may be visual, auditory, or a combination of both. The user may receive the instructions and make appropriate adjustments.
- a user may be wearing a biometric tracker (e.g., an exercise monitor, whether wrist, torso, or otherwise attached). If so, biometrics (e.g., heart rate) may be provided to the virtual software instructor (e.g., via Bluetooth). The virtual software instructor may take the biometric readings into account when providing instructions (e.g., increase or decrease cadence).

- the virtual software instructor may take the biometric readings into account when providing instructions (e.g., increase or decrease cadence).
- remote subsystem 220 may include a weather data source 236 .
- Current weather conditions e.g., temperature, humidity, etc.
- the associated smart device application may also serve various functions in addition to that of a virtual instructor.
- the application may, for example, allow for connection and data sharing between users in the mechanism's user community. Users can connect with others based on exercise styles, strength and ability, geographic location, schedule, and experiences. See FIGS. 31 .
- An exercise system may also have additional integrated electronics (e.g., lights, lasers, and/or speakers) that provide both operational and instructional functionality.
- FIG. 40 illustrates an example integrated electronics.
- the electronics include laser light projectors 121 , single lights 122 , speakers 123 , and strip lights 124 .
- Other implementations may include fewer, additional, and/or a different arrangement of electronics.
- the lift point on which the “lifter” grabs and/or the member on which the “liftee” stands to yield the desired felt resistance can be further highlighted through the illumination of lighting elements (e.g., single light 122 or strip lights 124 ) mounted on or adjacent to the respective members and/or through laser light projectors 121 projecting onto those respective members or components.
- Laser lights 121 would also allow for the projection of graphics and text onto mechanism members and/or the ground to provide more redundant instruction 125 and help mitigate unintentional misuse.
- Lighting elements also can be incorporated into the load determination system to more redundantly alert users when the system is over strained.
- Speakers 123 could provide verbal instruction, auditory warnings, and other audio material from the software application or of the user's choosing (e.g., music).
- Frame 2 may be made of various materials.
- the frame may be made of aluminum, polymer, or composite. Differing loads on frame members may result in these differing members being made from different materials to accommodate these higher or lower or different types of (e.g., compression, tension, torsion, shear, etc.) loads.
- certain members may be replaced with I-beam members (e.g., composed of a light polymer, such as one with a metal exoskeleton or a glass-filled nylon with a metal endoskeleton).
- the frame connectors and hinges may be made of aluminum or steel and may be made by machining (e.g., CNC) or cast.

- steel e.g., stainless
- Paint and finish may be applied to the mechanism as appropriate to mitigate corrosion.
- frame 2 is made from various subassemblies. Considering the interconnected nature of the design, all major components are, to an extent, load bearing, have structural ramifications on other members, and impact joint paths during collapse. Detailed below are the aspects unique to each subassembly, for a particular implementation.

Abstract
A multifunctional fitness system may allow for high-resistance exercises through the distribution of weight upon a frame pivoting on the ground. In particular implementations, while a user lifts one end of the frame, the opposite end pivots. The weight of another person (and/or that of conventional weighted plates) can be placed on the frame in locations yielding the desired leverage and, thus, resistance felt by the lifter. The frame may have various axes upon which it can pivot and grip points, thus offering a broad range of exercises that can be conducted. Reorienting the frame to be resting on differing sides results in additional feasible exercises. Optional integrated electronics (typically in conjunction with existing smart devices) may use kinematics and/or structural flexing to calculate felt resistance and provide automated instruction to the various users. The may also collapse into a compact, rollable configuration for easy transport.
Description
- This application claims priority to U.S. Patent Application No. 63/262,372, which was filed on Oct. 11, 2021. This prior application is herein incorporated by reference in its entirety.
- The size and weight of high-resistance training equipment make it inherently expensive, bulky, and difficult to transport. This leaves high-resistance training consumers with the options to (a) pay recurring fees to attend gyms, (b) buy expensive equipment themselves to place in a steadfast location, or (c) reduce the resistance and alter the methods with and by which they train. Time and time again, however, science has proven that there is no substitute for high-resistance training in regards to strength improvement, muscle development, and the efficiency of caloric depletion.
- Where heavy, bulky equipment is not available, users typically use their own body weight for exercises (i.e., push-ups, pull-ups, lunges, etc.). But body weight exercises typically result in relatively low-resistance/high-repetition workouts. Ideally, a means would exist that would allow users to utilize their and other's body weight to perform both low-resistance/high-repetition and high-resistance/low-repetition exercises, all while allowing for collaborative and team building workouts.
- A multifunctional fitness system may provide high-resistance exercises through the distribution of weight upon a frame that pivots on the ground. In particular implementations, while a user lifts one end of the frame, the opposite end pivots. The weight of another person and/or conventional weights can be placed on the frame at various locations to produce the desired leverage and, thus, resistance felt by the lifter. The frame may also have various axes upon which it can pivot and grip points, thus offering a broad range of exercises that can be conducted. Reorienting the frame to be resting on differing sides may result in additional feasible exercises. Optional integrated electronics (typically in conjunction with existing smart devices) may use kinematics and/or structural flexing to calculate felt resistance and provide automated instruction to the various users. The may also collapse into a compact, rollable configuration for easy transport.
- In one general aspect, an exercise system includes a frame having a multitude of linked members. The frame may be configured to be reoriented onto various sides thereof to provide a user with different groups of exercises for each orientation, with at least some of a first group of exercises involving the pivoting of the frame about an end. In some implementations, the first group of exercises may also involve pivoting the frame about a second end.
- In particular implementations, the frame has three orientations in which exercises may be performed, each with its own group of exercises. A second group of exercises may, for example, involve pivoting the frame about a different end than the first group of exercises. Additionally, at least some of the second group of exercises may involve sliding of the frame on the ground. The frame may be configured to resist sliding on the ground for the first group of exercises and/or to assist sliding on the ground for at least some of the second group of exercises. In certain implementations, the frame has a bottom side, a back side, and a front side, and the orientations of the frame include upright, on its back, and on its front.
- The frame may, for example, include a base, a vertical section, and a top section when in an upright orientation. The vertical section may be hingedly attached to the base and/or hingedly attached to the top section. In particular, implementations, the base may include two portions that are hinged to each other.
- The frame may be configured to support a person such that the person acts as a weight for a number of exercises. In certain implementations, the frame may be configured to support a person at multiple locations such that the resistance felt by a user is altered.
- The frame may also be configured to collapse along a single degree of freedom. In certain implementations, the frame may collapse to less than one-half of its expand volume, and in some implementations, the frame may collapse to less than one-third of its expanded volume.
- The system may also include a mechanical overload indicator coupled to the frame. Additionally, the system may include a mechanical exertion level indicator coupled to the frame.
- The system may further include integrated electronics coupled to the frame to detect strain thereon and a transmitter to wirelessly send the detected strain to a remote computing device. The computing device may be configured to receive the strain indications and determine an exertion level for the exercise being performed. The compute device may also be configured to provide exercise instructions to a user. In some implementations, the computing device may be attached to the frame.
- In certain implementations, the system includes light emitting electronics integrated into the frame to provide instruction and safety features for the exercise being performed. The system may also include audio electronics integrated into the frame to provide instruction and safety features for the exercise being performed.
- Various implementations may include one or more features. For example, an exercise system may provide a multitude of strength building exercises of varying resistance for both arms and legs without having to rely on conventional weights. Among other things, this may allow the exercise system to be used by users of varying strength and make the exercise system more portable. As another example, an exercise system may provide an indication of exerted effort (e.g., force) even if conventional weights are not being used. As an additional example, an exercise system may be collapsible into an easily storable and/or transportable configuration. Additional features will be evident to those skilled in the art in light of the following written description and figures.

-
FIG. 1 illustrates anexample exercise system 1. In one aspect,system 1 allows for high-resistance exercises through the distribution of one's own body weight and/or that of another upon aframe 2. - As shown,
frame 2 is composed of a number of hinged linkage structures that allow the frame to collapse (to be discussed in more detail below) into a volume that is less than 50% of its expanded volume and, in some cases, less than 33%. The linkage structures include adeadlift linkage assembly 10, left and rightsled linkage assemblies linkage assembly 30, a sledconnector linkage assembly 40, asquat linkage assembly 50, left and right dipsled linkage assemblies rod assembly 70, and left and rightdip connector assemblies - In operation,
frame 2 has three use orientations that are yielded from rotating the frame along its edges to rest on different faces as demonstrated inFIG. 2 . Each of these orientations (labeled A, B, C) allow for a different group of feasible exercises to be performed by a user. In Orientation B,squat linkage assembly 50 and dip sled linkage assemblies 60 provide a base forframe 2, dip standinglinkage assembly 30 provides a vertical section forframe 2, anddeadlift linkage assembly 10 provides a top section forframe 2. These assemblies serve different roles in Orientation A and Orientation C. - Orientation A provides two
pivot axes FIG. 2 . As a pivot axis is stationary on the ground, the user (lifter) lifts the opposite end of the frame, lifting the leverage weight thereof. Between the lifter and the pivot axis, the weight of another person (“liftee”) or one or more weighted plates may be placed on the structure in a location yielding the desired leverage and, thus, resistance felt by the lifter. Additionally, the resistance offered by a liftee or weight plate may be adjustable by varying the location of the frame—the further the liftee is from the pivot axis, the greater the felt resistance by the lifter. - On the end where
pivot 19 is located in Orientation A is a bar (not viewable here) at about shin height for conventional “over-the-bar” lifts whose design allows for both straight and parallel grips (seeFIG. 19 ). And on the end wherepivot 34 is located in Orientation A is a height-adjustable bar (not viewable here) for “under-the-bar” lifts. Given these two bars, their respective pivot axes, and the general location of linkage members in this orientation, variations of the following exercises can be conducted: - Squats (
FIG. 3 ) - Leg Press (
FIG. 4 ) - Shoulder Press (
FIG. 5 ) - Deadlifts (
FIG. 6 ) - Bent-Over Rows (
FIG. 7 ) - Upright Rows (
FIG. 8 ), utilizing a strap fixed to the frame - Biceps Curls (
FIG. 9 ), utilizing a strap fixed to the frame - Over-Head Tricep Extensions (
FIG. 10 ), utilizing a strap fixed to the frame - Shrugs (
FIG. 11 ) - Dips (
FIG. 12 ), utilizing removable load-bearing members (e.g., bars) - Orientation B is yielded from rotating the frame about
pivot 34 so that it rests on the side/face of the height-adjustable bar as seen inFIG. 2 , resulting in a taller structure. The bar previously at shin height in Orientation A is elevated higher in Orientation B, thus allowing for variations of the following exercises: - Pull-Ups (
FIG. 13 ) - Leg-Assisted Pull-Ups (
FIG. 14 ) - The bar onto which the user holds for these exercises is configured in a manner in which various grip orientations are permitted as seen in
FIG. 20 . - Orientation C is yielded from rotating the mechanism about
pivot 66 in Orientation B so that the Orientation A pivots 19, 34 are pointed upward as seen inFIG. 15 . On one end of the mechanism in Orientation C, the left side as viewed inFIG. 2 ,pivot 66 allows the opposite end to be functionally lifted. However, the other linkages contacting the ground in Orientation C are angled as to allow the sliding of the mechanism in one direction (i.e., to the right in Orientation C). These features and the general location of the linkage members in this orientation allow variations of the following lifts to be conducted: - Sled Push (
FIG. 15 ) - Sled Pull (
FIG. 16 ), utilizing a large strap - Hanging Rows (
FIG. 17 ) - Bench Press (
FIG. 18 ), utilizing a narrow elevated surface - A feature of
system 1 is that a liftee may be positioned at different locations onframe 2. For example, inFIG. 3 , the liftee is shown as standing on an intermediate horizontal member in Orientation A. However, the liftee could be positioned on the horizontal member immediately behind the lifter, thus increasing resistance, or positioned on the horizontal member farther from the lifter, thus decreasing resistance. Thus,system 1 allows users of different sizes to work out with each other. Moreover, one liftee can provide varying resistance to a lifter. - When placement of the liftee at maximum distance from the pivot axis for an exercise still yields an inadequate amount of resistance felt by the lifter, the system allows for additional weight to be applied. For example, the frame may be designed and strengthened as to allow multiple persons to distribute their weight simultaneously on the frame for greater resistance, as illustrated in
FIG. 21 . When persons are not available to serve as the liftee, plate mounts are also integrated to allow the use of weighted plated as the primary means of resistance, as seen inFIGS. 22, 23 , and 24. Weighted plates and liftee(s) can be used in conjunction if needed, as seen inFIG. 25 . - A feature of the
system 1 is its ability to be transported easily. The linkage system offrame 2, for example, has one degree of freedom when unlocked, allowing it to collapse into a closed/condensed configuration. In particular, with the removal of just twopins FIG. 26 , to allow for transport and/or storage in confined areas. Certain implementations, however, may use different locking mechanisms or may not collapse at all. - To collapse
frame 2 when it is fully expanded and locked, pins 84 a, 84 b are removed (Step 1). Then, sled linkage assemblies 20 (only one of which is viewable inFIG. 26 ) are swung outward relative to deadlift linkage assembly 10 (counterclockwise inFIG. 26 ), which causes sledconnector linkage assembly 40 to pull dip sled linkage assemblies 60,squat linkage assembly 50, and dip connector assemblies 80 towards deadlift linkage assembly 10 (Step 2). Next, dip standinglinkage assembly 30 is swung towards deadlift linkage assembly 10 (counterclockwise inFIG. 26 ), moving dip sled linkage assemblies 60,squat linkage assembly 50, and dip connector assemblies 80 inside deadlift linkage assembly 10 (beginning inStep 3 and ending early in Step 4). Then, sled linkage assemblies 20 are swung back towarddeadlift linkage assembly 10, completing the collapse (Step 4). - In particular implementations,
frame 2 may be locked into place when collapsed. For example, most any of the linkage members that are close to each other may be coupled (e.g., pinned) together. In certain implementations, the members that were pinned in the expanded configuration may be pinned together in the collapsed configuration, CompareStep 1 withStep 4FIG. 26 . - During the collapse process,
wheels 17 may emerge from one side of the frame allowing it to be easily rolled, as illustrated inFIG. 27 . (The wheels are present inFIG. 1 , but are hidden by various members due to the chosen perspective.) - As a safety measure, a
mechanical overload indicator 90 may be built into an exercise system, as illustrated inFIGS. 1 and 28 .Overload indicator 90 includes a cable-spring assembly 91 placed onframe 2 so that flexion thereof under loads will place the cable and spring (connected in series) under tension. Ashroud 92 covers the spring and part of the cable in a manner such that an overload indicator 93 (e.g., a marked portion of the cable) is hidden in an unloaded condition. Under load, however, the flexion of the frame yields in the exposure of more of the cable. Indicator marking 93 is placed on the cable so that the maximum allowed load will result in the marking's visibility from undershroud 92, thus indicating applied force should be reduced (seeFIG. 28 ). Utilizing the same principle, incremental ticks on the cable may allow for felt resistance estimations. - An exercise system may also have integrated electronics that allow for more functionally precise means of determining felt resistance. Placed in series with the cable/
spring assembly 91 inFIG. 28 , for example, is astrain gauge 94. An instrumentation-driver/battery/transmitter assembly 95 gathers the strain measured by the strain gauge during the frame's flexion under load as seen inFIG. 28 . Additionally, in certain embodiments, onboard accelerometers may gather kinematic data. Gathered information is sent via a transmitter (e.g., via Bluetooth or Zigbee) to a user's smart device (e.g., a lifter's smart phone, smart watch, or tablet) where algorithms are used to calculate the maximum strain, felt resistance, cadence, etc. Smart devices may not only display the calculated data but store the data as well. Storing records of the conducted exercises, user's felt resistance, lifting cadences, and other available biometric data allows for a “virtual instructor” within software onboard the associated smart device to plan and guide the users' workouts through visual and auditory means, as shown inFIG. 30 . - A general layout of example elements for a load
determination system architecture 200 is seen inFIG. 29 . In particular implementations, the “virtual instructor” software may be onboard a computer integrated in the mechanism itself rather than utilizing a user's smart device as the software driver. - Load
determination system architecture 200 includes asubsystem 210 onboard the frame and aremote subsystem 220. In particular implementations, all or a portion ofremote subsystem 220 may be onboard the frame. -
Onboard subsystem 210 includes a number of strain gauges 212. Strain gauges 212 may be mounted on the same frame member and/or different frame members. If mounted on the same member, the strain gauges may measure strains in different axes. - Coupled to strain gauges 212 is a
controller 214.Controller 214 is typically an electronic logic device (e.g., a microcontroller) and is responsible for receiving the readings from the strain gauges (usually in analog form) and preparing them for further analysis (e.g., by converting them to digital form). - The prepared data is sent via a
transmitter 216 toremote subsystem 220.Transmitter 216 typically works by wireless techniques (e.g., radio frequency), but could use wired techniques in certain implementations. -
Onboard subsystem 210 also includes anaccelerometer 218, which can measure the motion (e.g., acceleration) thatframe 2 is subjected to. The data from accelerometer is also sent totransmitter 216. -
Remote subsystem 220 may be a smartphone, a tablet, or any other appropriate electronic logic device (e.g., having an electronic processor, memory, and input/output capability).Remote subsystem 220 may only be remote in the aspect that it is connected toonboard subsystem 210 through a communication link, as opposed to being at some large geographic distance from it. In some operations,remote subsystem 220 may actually be on or inside the periphery of the frame. -
Remote subsystem 220 includes areceiver 222 for receiving data fromtransmitter 216. The data is then fed to the appropriate calculator (e.g., an electronic logic device or a piece of code operating on an electronic logic device). For example, data from the strain gauges may be fed to astrain calculator 224, which may determine the actual strain occurring on the system. The actual strain may be compared to the maximum allowable strain via acomparator 230 to make sure the frame is not being overtaxed. As another example, data from the strain gauges may be fed to a resistance calculator, which may determine how much resistance (e.g., weight) is being felt by the user. The amount of axial strain on a linear member is, for example, proportionally related to the force axial applied thereto. Depending on the size and location of a liftee, the resistance felt by a lifter can vary greatly. Thus, being able to determine the effective resistance, provides the lifter with some idea of what and how they are doing with the particular exercises. Kinematic data may be fed to akinematic data calculator 228, which may use the acceleration data from theaccelerometer 218 to qualify the movement, orientation, and displacement of the mechanism. - A
virtual instructor 232 may use software algorithms to combine, compare, reconcile, and analyze the incoming data (from 224, 240, 226, 228, 236, 238, and/or 240) to determine real-time instructions to optimize use of the system. Based on the analyzed data, thevirtual instructor 232 may provide those determined instructions to the lifter (e.g., increase repetitions, decrease repetitions, reposition liftee, add weight plates, alter cadence, etc.). The instructions may be communicated via auser interface 234, which may be visual, auditory, or a combination of both. The user may receive the instructions and make appropriate adjustments. - In some implementations, a user may be wearing a biometric tracker (e.g., an exercise monitor, whether wrist, torso, or otherwise attached). If so, biometrics (e.g., heart rate) may be provided to the virtual software instructor (e.g., via Bluetooth). The virtual software instructor may take the biometric readings into account when providing instructions (e.g., increase or decrease cadence).
- Additionally,
remote subsystem 220 may include aweather data source 236. Current weather conditions (e.g., temperature, humidity, etc.) may be taken into account by the virtual instructor software in providing instructions to the user. - The associated smart device application may also serve various functions in addition to that of a virtual instructor. The application may, for example, allow for connection and data sharing between users in the mechanism's user community. Users can connect with others based on exercise styles, strength and ability, geographic location, schedule, and experiences. See
FIGS. 31 . - An exercise system may also have additional integrated electronics (e.g., lights, lasers, and/or speakers) that provide both operational and instructional functionality.
FIG. 40 illustrates an example integrated electronics. In this implementation, the electronics includelaser light projectors 121,single lights 122,speakers 123, andstrip lights 124. Other implementations may include fewer, additional, and/or a different arrangement of electronics. - During use of the mechanism, the lift point on which the “lifter” grabs and/or the member on which the “liftee” stands to yield the desired felt resistance can be further highlighted through the illumination of lighting elements (e.g.,
single light 122 or strip lights 124) mounted on or adjacent to the respective members and/or throughlaser light projectors 121 projecting onto those respective members or components.Laser lights 121 would also allow for the projection of graphics and text onto mechanism members and/or the ground to provide moreredundant instruction 125 and help mitigate unintentional misuse. Lighting elements also can be incorporated into the load determination system to more redundantly alert users when the system is over strained.Speakers 123 could provide verbal instruction, auditory warnings, and other audio material from the software application or of the user's choosing (e.g., music). -
Frame 2, shown inFIG. 1 , may be made of various materials. For example, the frame may be made of aluminum, polymer, or composite. Differing loads on frame members may result in these differing members being made from different materials to accommodate these higher or lower or different types of (e.g., compression, tension, torsion, shear, etc.) loads. In particular implementations, certain members may be replaced with I-beam members (e.g., composed of a light polymer, such as one with a metal exoskeleton or a glass-filled nylon with a metal endoskeleton). The frame connectors and hinges may be made of aluminum or steel and may be made by machining (e.g., CNC) or cast. It is possible that frame connectors or hinges subjected to lower loads could be made of polymer. Under circumstances where polymer is a satisfactory material for both the connector or hinge and the associated member onto which it is mounted, the components can be integrated together as a single polymer hinge-member or connector-member part and may be made by injection molding. High strength members (e.g., the deadlift bar) may be made of steel (e.g., stainless). Paint and finish may be applied to the mechanism as appropriate to mitigate corrosion. - As mentioned above,
frame 2 is made from various subassemblies. Considering the interconnected nature of the design, all major components are, to an extent, load bearing, have structural ramifications on other members, and impact joint paths during collapse. Detailed below are the aspects unique to each subassembly, for a particular implementation. -
FIG. 32 illustrates an example ofdeadlift linkage assembly 10.Deadlift linkage assembly 10 includes adeadlift bar 11, a subframe composed of side frame members 13 andcross members -
Deadlift bar 11 is typically made from steel bars that have been cut, welded, and textured.Deadlift bar 11 serves as a lift point in Orientation A (FIG. 6 ), the pull-up bar in Orientation B (FIG. 14 ), and a lift point in Orientation C (FIG. 18 ). - The subframe composed of side frame members 13 and
cross members cross members Cross members - In certain implementations, traction material (e.g., rubber or polymer, possibly texturized) may be added to the cross members to prevent slipping when a user is standing on them. The texturized material may generally be any material that is fairly durable and has increased friction with a shoe sole.
- Side frame members 13 provide part of the base for a frame when in Orientation A and the vertical spine of the frame when in Orientation B. Side frame members 13 also connect the other components in the deadlift linkage assembly. Side frame members 13 have a slight bend in them to establish a pivot point in Orientation
A. Cross members - Squat pivots 19 are typically made of hard polymer. They are designed to slightly impale the ground (e.g., dirt, sand, or grass) to serve as a stationary fulcrum when the entire mechanism is lifted from the opposite side (see
FIG. 5 ). - Plate posts 15 are typically made of hard polymer and secure weight plates to the mechanism when plates are being used for resistance. The plate posts may also be used by a liftee to stabilize their foot placement.
- Hinges 12, 18 are typically made of solid aluminum and connect the deadlift linkage assembly to adjacent assemblies. In particular implementations, hinges 12, 18 could be made of polymers, especially where stress (less thereof) allows.
-
Deadlift linkage assembly 10 may also include aload determination assembly 100, an example of which is illustrated inFIG. 38 .Load determination assembly 100 includescable 102,spring 104, andstrain gauges 106, connected in series usingchain links Cable 102 and chain link 112 are secured to a frame member byplates 101.Plates 101 may be screwed, riveted, welded, or otherwise attached to the frame member. Awire 105 preventsspring 104 from being overstrained. - Strain gauges 106,
spring 104, and a portion ofcable 102 are located inside a shroud/housing 113 (shown in shadow line here). As the frame member is placed under load,spring 104 may expand, allowing more ofcable 102 to be exposed fromhousing 113. A section ofcable 102 may be marked so that high loads may be visually indicated to a user. -
Electrical wire 114 connectsstrain gauges 106 to a single instrumentation-driver/battery/transmitter assembly 115, typically encapsulated in polymer packaging. Awire 116 connects additional strain gauges integrated into the system to the instrumentation-driver/battery/transmitter assembly 115. The additional strain gauges are not necessary, however, for load determination. -
Load determination assembly 100 as a whole serves to determine felt resistance (by the lifter) by both analog means and digital means (sending gathered data via the transmitter to a paired smart device for further interface with the user). The instrumentation-driver/battery/transmitter assembly 115 can also serve as a centralized power source and controller for additional integrated electronics (e.g., lights, lasers, and speakers) via connection throughwire 116. The controller may, for example, be a microcontroller, a microprocessor, or any other electronic logic device, and the power source may be a battery. - Additional strain gauges and accelerometers may be placed throughout the mechanism to allow for more refined calculations of applied forces or other strains on the frame.

FIG. 33 illustrates an example of sled linkage assemblies 20 and dip standinglinkage assembly 30. Sled linkage assemblies 20 connect at one end todeadlift linkage assembly 10, and dip standinglinkage assemblies 30 also connect at one end to the deadlift linkage assembly. - Dip standing
linkage assembly 30 includes side members 31, 32,cross member 37, andconnectors 39. Dip standinglinkage assembly 30 is typically made from aluminum tubing that is bent, cut, welded, and affixed together withconnectors 39, which may be aluminum or steel. Side members 31, 32 andcross member 37 could be made of other suitable materials (e.g., polymers) in other implementations as long as they satisfied the loading requirements, although weight and cost would be additional factors. -
Cross member 37 spans the assembly and provides an area on which a person or persons can stand to provide resistance to the lifter during Orientation A lifts. Traction material may be added to cross member to prevent slipping when a user is standing on it Side members 31, 32 connect the other components in the dip standing linkage assembly. - At one end of side members 31 are deadlift pivots 34. Deadlift pivots 34 are typically made of hard polymer, but could be made of any other relatively hard material. Deadlift pivots 34 are designed to slightly impale the ground (e.g., dirt, grass, or sand) to serve as a stationary fulcrum when the entire frame is lifted from the opposite side (
FIG. 6 ). - Connected to cross member 37 (and possibly connectors 39) are plate posts 38. Plate posts 38 are typically made of hard polymer and secure weight plates to the mechanism when plates are being used for resistance. Plate posts could also be made of any other relatively hard material. Plate posts 38 may also provide a location for a liftee to stabilize their feet when being lifted.
- Hinges 35, 33 connect dip standing
linkage assembly 30 to adjacent assemblies. Hinges 35, 33 are typically made of solid aluminum. Hinges 35, 33 could be made of other suitable materials (e.g., polymers) in other implementations as long as they satisfied the loading requirements, although weight and cost would be additional factors. - Dip standing
linkage assembly 30 also includeswheels 36.Wheels 36 are typically made of a dense rubber and ball bearings, but any material that is relatively impact resistant may be used. Upon collapse of the frame, the wheels assume an ejected position to allow the user to transport the mechanism via rolling (FIG. 27 ). - Sled linkage assemblies 20 includes sub-frames 22, which are typically made from aluminum tubing that is cut, bent, welded, and affixed together. Sub-frames 22 could be made of other suitable materials (e.g., polymers) in other implementations as long as they satisfied the loading requirements, although weight and cost would be additional factors. Sub-frames 22 act as sled “skis” when the mechanism is in Orientation C (
FIG. 2 ). - At each end of sub-frames 22 are hinges 21, 25. These are typically made of solid aluminum and connect the sled linkage assembly to adjacent assemblies. Hinges 21, 25 could be made of other suitable materials (e.g., polymers) in other implementations as long as they satisfied the loading requirements, although weight and cost would be additional factors.
- Sub-frames 22 also include plate posts 23. Plate posts 23 are typically made of hard polymer and, in operation, secure weighted plates to the mechanism when plates are being used for resistance (see
FIG. 24 ). Plate posts could be made of any other relative hard material. - Sub-frames 22 further include frame guards 24 on their outer surfaces. Frame guards 24 are typically made from a hard polymer, but could be made of any other relatively hard material. Frame guards serve to prevent damage to the frame while it is in Orientation C (see
FIG. 2 ). - Connected to each sub-frame 22 is a locking
arm 26. Lockingarms 26 serve to hold the frame in the expanded configuration. In particular implementations, lockingarms 26 may be homogenous pieces with sub-frames 22. -
FIG. 34 illustrates an example ofsquat linkage assembly 50 and sledconnector linkage assembly 40.Squat linkage assembly 50 connects at one end to dip standinglinkage assembly 30, and sledconnector linkage assembly 40 connects at one end to sled linkage assemblies 20. -
Squat linkage assembly 50 includes side frames 51 and across member 56. Side frames 51 andcross member 56 are typically made from aluminum tubing that is bent, cut, welded, and affixed together. Side frames 51 andcross member 56 could be made of other suitable materials (e.g., polymers) in other implementations as long as they satisfied the loading requirements, although weight and cost would be additional factors.Cross member 56 spans the assembly and provides structural support and a potential lift point. Side frames 51 connect the other components in the squat linkage assembly. -
Squat linkage assembly 50 also includes a height-adjustablesquat bar assembly 53 composed of abar 54,plates 57, and apin 58.Bar 54 is typically made from a textured steel, but could be made of any other relatively hard material as long as it has the necessary strength.Plates 57 are typically made of metal (e.g., steel) and are elongated with holes therein. Side frames 51 include a jog (e.g., an S bend) to accommodateplates 57 so that they do not contact the ground. In some uses cases (e.g., on loose soil), there may, of course, be some contact with the ground, but if the forces carried by the plates are relatively low, this should not cause a problem. -
Bar 54 serves as a lift point during manipulation of the frame. Depending on the height of the lifter,bar 54 can be placed in higher or lower holes inplates 57 to yield the proper rest height.Pin 58 keeps the bar secure at the desired level. - At each end of side frames 51 are hinges 53, 55. Hinges 53, 55 are typically made of solid aluminum and connect the squat linkage assembly to adjacent assemblies. Hinges 53, 55 could be made of other suitable materials (e.g., polymers) in other implementations as long as they satisfied the loading requirements, although weight and cost would be additional factors.
- On the exterior of each side frame 51 are frame guards 52. Frame guards 52 are typically made from a hard polymer, but could be made of any other relatively hard material. Frame guards 52 prevent damage to the frame while it is in Orientation B (see
FIG. 2 ). - Sled
connector linkage assembly 40 includes side frames 41 and across member 44. Side frames 41 andcross member 44 are typically made from aluminum tubing that is cut and affixed together. Side frames 41 and/orcross member 44 could be made of other suitable materials (e.g., polymers) in other implementations as long as they satisfied the loading requirements, although weight and cost would be additional factors. -
Cross member 44 spans the assembly and provides an area where a person or persons can stand in order to provide resistance in Orientation C exercises. Traction material may be added to cross member to prevent slipping when a user is standing on it. Side frames 41 connect the other components in the sled connector linkage assembly. - At each end of side frames 41 are hinges 42, 43. Hinges 42, 43 are typically made of solid aluminum and connect the sled connector linkage assembly to adjacent assemblies. Hinges 42, 43 could be made of other suitable materials (e.g., polymers) in other implementations as long as they satisfied the loading requirements, although weight and cost would be additional factors.

FIG. 35 illustrates an example of dip sled linkage assemblies 60. Each dip sled linkage assembly 60 includesmembers Members 62 are coupled at one end to squatlinkage assembly 50, members 64 are coupled at one end to dip connector assemblies 80, and each pair ofmembers 62, 64 are coupled together by aconnector 61.Members 62 serve as sled “skis” when the mechanism is in Orientation C (FIG. 2 ). Also coupled to eachconnector 65 is amember 63, which is generally orthogonal toadjacent member 62. Eachmember 63 is adapted to receive an end of spanningbar assembly 70. -
Members 62, 64 are typically made from aluminum tubing that is bent, cut, welded, and affixed together withconnectors 65, which are typically made of solid aluminum.Member 63 is typically made from aluminum tubing that is cut and affixed together toconnectors 65, but may be integrated intoconnectors 65 as a homogenous piece in certain implementations.Members - Hinges 66, 67 are typically made of solid aluminum and connect the dip sled linkage assemblies to adjacent assemblies. Hinges 66, 67 could be made of other suitable materials (e.g., polymers) in other implementations as long as they satisfied the loading requirements, although weight and cost would be additional factors.
- Each
member 62 includes aframe guard 61 on the exterior thereof. Frame guards 61 are typically made from a hard polymer, but could be made of any other relatively hard material. Frame guards 61 prevent damage to the frame and serve as a pivot axis while the mechanism is in Orientation C (seeFIG. 2 ). Frame guards 61 also prevent damage to the frame while the mechanism is in the Orientation B (seeFIG. 3 ). -
FIG. 36 illustrates an example spanninghinge bar assembly 70. As illustrated, spanninghinge bar assembly 70 includes a metal (e.g., steel)bar 71 andspacers hinge bar assembly 70 connects the sled connector linkage assembly and the dip sled linkage assembly while still allowing rotational freedom from one another.Bar 71 provides structural support and a hinge point. -
FIG. 37 illustrates example dip connector assemblies 80. Each dip connector assembly 80 include aside frame 81 and hinges 82, 83. Side frames 81 are typically made from aluminum tubing that is bent and cut to size and serve to limit the degrees of freedom allowed while collapsing (SeeFIG. 26 ). In particular, connecting the dip sled assembly and the deadlift assembly with a link/member yields a one degree of freedom mechanism. Hinges 82, 83 are typically made of solid aluminum and connect the dip connector linkage assembly to adjacent assemblies.Side frame 81 and hinges 82, 83 could be made of other suitable materials (e.g., polymers) in other implementations as long as they satisfied the loading requirements, although weight and cost would be additional factors. - On the inside of each
side frame 81 is a female portion of acollapse hinge 85.Hinge portions 85 are typically made of bent metal (e.g., steel) and receive one of pins 84 to connect the dip connector linkage assembly to sled linkage assembly 20, resulting in zero degrees of freedom in the frame when expanded. Upon removal of pins 84, the dip connector linkage assembly and the sled linkage assembly are no longer fixed together, thus, allowing the frame to collapse (seeFIG. 26 ) with one degree of freedom. -
FIG. 39 illustrates the expanded and collapsed dimensions forsystem 1 for an example implementation. As illustrated,system 1 is about 90 inches tall and 55 inches deep, in Orientation B, when expanded and about 46 inches tall and 31 inches deep when collapsed.System 1 is about 45 inches wide. Thus,system 1 may be transported in a van or larger SUV when collapsed. In terms of volume,system 1 collapses to less than about one-third of its volume. - The drawings shown herein are believed to provide fairly accurate representations of the illustrated implementations. Thus, lengths, angles, relative sizes, positioning of parts, orientation of parts, and like information can be readily extracted therefrom by one of skill in the art. However, the invention is not limited to the exact dimensions/sizes shown (e.g., bend radiuses, angles, etc. may need to be adjusted for various implementations).
- A number of implementations have been shown and discussed, and several others have been suggested. Moreover, those of skill in the art will readily recognize that a variety of additions, deletions, substitutions, and transformations may be made while still achieving a multifunction, reorientable, collapsible exercise system. Thus, the scope of protected matter should be judged based on the claims, which may encompass one of more aspects of one of more implementations.
