Description

DESCRIPTION

Exercise device

Field of the invention

The present disclosure relates generally to an exercise device and, more specifically, to an elastic resistive exercise device that includes a series of two or more loops.

Background of the invention

Endurance strength exercises have long been incorporated into athletic training and therapy regimens to help prevent injury, enhance performance, and rehabilitate muscles after injury or surgery. Conventional isometric or isotonic exercise devices have been used to enable means of resistance training and muscle therapy without the cost and space required by more complex and bulky equipment. In particular, many types of single loop bands or single strap bands of elastic material have been developed in the related art, which allow a user to practice their exercises based solely on the resistive action supplied by the band. For example, the user can exercise with a single loop band by holding the band towards one end with one hand or foot and attaching the other end of the band to a fixed object, such as a door, or by holding the other end with the hand. other hand or foot. Often, in order to obtain and maintain a proper grip on conventional bands, a user must loop the band multiple times around the hand or foot, or tie knots at an appropriate location on the band.

Document US 2008274863 provides a portable, elastic and resilient exercise cuff that can be placed around the torso and the extremities of the body to achieve muscular strengthening and physical preparation, which, in general terms, is composed of an elastic oblong section large having a plurality of smaller elastic positioning sections connected at its opposite ends with the larger oblong center section and the smaller positioning sections joined together to form a multi-piece muscle exercising device. The exercise cuff is arranged to receive the limbs of the human body to stretch and strengthen the muscles.

However, the methods referred to to provide effective grips at appropriate locations along a conventional band often cause damage to the band and / or localized pressure on the hand or foot area, that is, a cut by within the band due to considerable narrowing of the band in and around the knot area. To avoid this effect of the knotted band, the user can almost entirely make use of a finger grip, for example, rather than mounting the band on a larger portion of a limb, for example a wrist or ankle. . Some users, for example the elderly or those with considerable deterioration of the muscles of the hands or feet, for example, may not be able to grasp the bands effectively and may thus deviate from the therapeutic regimen. described by the doctor to strengthen or weaken damaged muscles and / or cause additional injuries to them. To alleviate this discomfort, some users may make use of special handles that have to be attached separately from the exercise device, resulting in additional cost and complexity, which can discourage users.

Accordingly, there is a need for an exercise device that allows easy and efficient use without the need to reconfigure the device with knots or without constricting loops, in which an isotropic nature of the material used to make the device can facilitate the device to be easily adjusted. it adapts to the shapes of the surfaces, providing a reduced glide in the assembly of the various objects, for example, while simultaneously being able to adapt to the contours of the anatomy of a user to contribute to their greater comfort. Additionally, an exercise device that is easy to manufacture is needed in order to achieve the aforementioned advantages with little or no modification on the part of the users.

Summary of the invention

In view of at least the stated needs, the present invention contemplates an exercise device that is capable of solving the above-described drawbacks. In one aspect, the present disclosure describes a device for exercising muscles that relies on the resistive properties of a material used to produce a series of flexible loops. The device is formed from preformed loops of elastic material joined together in a series or chain.

FIG. 9 also illustrates that the base portion 512 and the upper portion 514 may be connected in bonding zones 518 along their length, such that a plurality of loops 516 are formed between the base portion 512 and the upper portion 514. The loops 516 can be formed by connecting the base portion 512 and the upper portion 514 in any appropriate way, for example by one or more methods of heat setting, chemical bonding, adhesives, radio frequency, latex dipping, or ultrasonic welding, and the like. . In accordance with other aspects of the present disclosure, any appropriate tool or device can be used to form a bond zone 518 including saddles, for example, that enables the bond zone to exhibit homogeneous elongation substantially similar to elongation properties. from the other portions of the exercise device 500. As illustrated in the exemplary device 500 in FIG. 9, there are eight loops 516 periodically formed along the exercise device 500 with each individual loop 516 being separated by an attachment zone 518. In accordance with aspects of the present disclosure there may be between 6 and 12 loops along the length. of an exercise device, each loop 516 being approximately 15.24 cm in length in the unexpanded state, but any appropriate number of loops 516 may be used. In one aspect, it is envisioned that the exercise device may incorporate 9 loops or 11 loops total. Additionally, although the loops 516 shown in FIG. 9 have the same overall dimensions, the loops 516 may vary in size relative to each other so that various patterns of loops of different sizes 516 to form an exercise device 500. For example, alternate 4 "and 6" loops 516 or 6 "loops with a 12" center loop can be used.

With reference to FIGS. 10-12, illustrate various views of an enlarged portion of the exercise device 500 to show general concepts that can be applied to the device 500 as a whole. In one aspect, the attachment zone 518 of the exercise device 500 may extend continuously between each of the loops 516. Alternatively, as shown in FIGS. 10-12, each bond zone 518 defined between two loops 516 may include one or more bond spaces 530 in which the base portion 512 and the top portion 514 are not adhered to each other. Attachment spaces 530 can be used to help identify a cut zone to reduce a size of exercise device 500 without affecting the integrity of attachment area 518 where base portion 512 and upper portion 514 are located. effectively adhered or joined together.

In one aspect, each junction space 530 may divide a junction zone 518 into a first junction zone segment 518a and a second junction zone segment 518b. The junction space 530 can span less than 10 inches in length between the first junction zone segment 518a and the second junction zone segment 518b. In one aspect, a length of the bond space 530 ranges from 6.35mm to 12.7mm. The junction space 530 may form a micro-loop 535 when the first junction zone segment 518a and the second junction zone segment 518b are forced towards each other. At rest or while the first junction zone segment 518a and the second junction zone segment 518b are forcibly separated, the microloop 535 can be placed in a flattened or substantially flattened position.

Although the loops 516 of FIG. 9 are shown as open loops, FIGS. 10 and 12 illustrate that the loops 516 can be arranged flat when, for example, the exercise device 500 is in a general state of rest or, in particular, when the exercise device 500 is in a state of use, under tension, and the Loop 516 is not being used as a loop or handle. Accordingly, when in the closed state, a loop 516 is actually a two-layer application that provides a compact design and that provides a plurality of loops 516 for a multitude of grip options for the user.

As shown in FIG. 10, in general, the base portion 512 may be formed from a longitudinal extension of elastic material having a first end 520 and a second end 522, and the upper portion 510 may also be formed from a second longitudinal extension. of material having a first end 524 and a second end 526. For example, the manufacturing process 500 may include linear deposition of a material for the upper portion 514 onto the material for the base portion 512. The material may be a rolled material, for example, or a pipe material that is fed longitudinally from the coils. The material used for the base portion 512 and the upper portion 514 may be the same material, however each portion 512 and 514 may use a material that exhibits different material characteristics. An adhesion process, for example heat sealing or application of an adhesive, may be carried out to connect the base portion 512 and the upper portion 514 at predetermined intervals, and define the attachment zones 518 of the exercise device 500, which may be separated at equal intervals or intervals of varying length.

Junction areas 518, which may appear striated as in FIGS. 10 and 11, can be formed to have any desired appearance according to the configuration of the machining tools. In one aspect, grooves or other desired appearance may appear on exactly the first segment of the bonding zone 518a and a second segment 518b of the bonding zone, precisely joining the space 530 of the bonding zone 518 or both the space junction 530 as the first and second junction zone segments 518a, 518b. The grooves can serve to provide a visual guide for the cutting or separation of the devices of elastic layers adhered in one of the areas of attachment, allowing the customization of an exercise device or the separation of an exercise device from a set of multiple exercise devices.

In accordance with other aspects of the present disclosure, instead of a ridged crimping tool, a crimping tool can be used to provide any smooth, textured and / or embossed surface appearance. The material of the base portion 512, of the upper portion 514 can be configured to present a smooth, textured and / or embossed surface appearance.

In accordance with still further aspects of the present disclosure, for example large coils, rolls or folded stacks of a series of connected exercise devices 500 can be arranged, after which a professional can individually remove and form an individual exercise device 500 from of the assembly by taking one end of the series of connected exercise devices 500, transversely cutting at least one of the loops 516 or joining the spaces 530 to form an exercise device 500 with a desired length and / or number of loops 516. The The professional can in this way control the individual length of each exercise device 500 to suit the specific needs of the user, while maintaining a compact storage arrangement. Alternatively, the coil lengths of the connected exercise devices 10 can be marked along the attachment zones 518 at specific lengths to enable easy and efficient removal of a single exercise device 500 from the broader collection of devices. of exercise windings.

The consecutive loops 516 on the exercise device 500 allow for rapid positioning of the device 500, for example, when mounting the device on an object. Rather than having to tie the device 500 around an object, one end of the device 500 can be quickly wrapped around an appropriate mounting portion of the object and guided through one of the loops 516, preferably near the other end. of the device 500. Continued pulling on the first end of the device 500 can then simply squeeze a portion of the device 500 closing around the mounting portion and the fixed object. To quickly remove the exercise device 500, the user simply releases the active end of the device 500 and pulls the loop 16 through which the exercise device 500 was originally threaded. The threaded loop 516 eventually disconnects the active end and releases the active end to freely detach the exercise device 500 from the object.

A user typically relies on the resistive nature of the material used to construct the base portion 512 and the upper portion 514 of the exercise device 500. In this way, the base portion 512 and / or the upper portion 514 can be comprised of a elastic material that has a certain thickness and / or is dimensioned to confer a specific resistance range for a user who exercises with the device. In this way, an electrification system can be used to indicate a series of exercise devices that offer progressive resistance levels. For example, a system of appropriate numbers, colors, letters, symbols, patterns, or other markings may be used to indicate a system of exercise devices that offer progressive resistance levels.

In accordance with other aspects of the present disclosure, the elastic material used to construct the base portion 512 and the upper portion 514 of the exercise device 500 may be an isotropic material capable of similarly stretching, in any direction. The isotropic nature of the material makes it possible for the material to easily adapt to the shapes of the surfaces, providing a better grip, for example, when being mounted on various objects, while being able, simultaneously, to adapt to the contours of the user's anatomy. In one aspect, the isotropic material may be capable of elongation of at least 400% along a longitudinal extension of the exercise device 500 without reaching an elastic limit.
