Description

FIELD OF THE INVENTION

The present invention generally relates to a holder and support apparatus, and more specifically to a design with a wide holding range, applicable to portable electronic device ranging from 3 to 16 inches.

BACKGROUND OF THE INVENTION

The popularity of a wide range of digital contents and the availability of portable related devices propels the users to download the contents to the devices, such as, smart phone and tablet, for later viewing. Hence, the demands for an auxiliary apparatus to hold and support the device for comfortable viewing increase. Currently available in the market are usually support apparatuses able to hold and support one type of size, such as, for supporting 6-10 inches tablet, or for 3-5 inches smart phone, and so on. A general observation is that the maximum size and the minimum size that a conventional holder and support apparatus is less than 2:1. As the size of a smart phone is often one-fifth or one-third of the size of a tablet, the conventional holder and support apparatus cannot conveniently accommodate both smart phone and tablet.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a holder and support apparatus applicable to different types of portable electronic devices, of various sizes ranging from 3 inches to 16 inches, i.e., maximum size is about 3-5 times of the minimum size. In this manner, the present invention is applicable to most smart phones and tablets currently available in the market, and thus provides a one-size-fits-all solution to a variety of portable electronic devices.
To achieve the aforementioned object, the present invention provides a holder and support apparatus, including a support platform, at least two position adjustment sets, and at least two clamping sets. The support platform is for the electronic device to place on. The platform includes at least two guiding tracks, with each position adjustment set located at a guiding track. Each position adjustment set includes an arm and a lock element. The arm has a first end and a second end, where the first end can slide and rotate on the guiding track. The lock element is to fasten the first end of the arm to the guiding track. Each clamping set is located at the second end of the arm, including a fixing base and a clamping element on the fixing base. The fixing base, though attached to the arm, can rotate. A plurality of clamping elements can clamp to the side walls of the portable electronic device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 and FIG. 2 show a schematic view and side view of the present invention respectively. The hold and support apparatus of the present invention can be used to clamp portable electronic devices of different sizes. The hold and support apparatus includes a support platform 1, at least two position adjustment sets 2, and at least two clamping sets 3. Support platform 1 includes at least two guiding tracks 11, with each position adjustment set 2 located at a guiding track 11. Position adjustment set 2 can use guiding track 11 as center for rotation angle adjustment and slide position adjustment, shown as the dash-line drawing in FIG. 2. Each clamping set 3 is installed to position adjustment set 2 for rotation angle adjustment. In this manner, the present invention can change the clamping size formed by clamping sets 3 to clamp devices of different sizes through sliding or rotating position adjustment sets 2 along guiding track 11 on support platform 1 so as to change the positions of clamping sets.
The following describes each component in details. Support platform 1 is a flat long stripe-shaped plate, with four corners extending outwards. The center of the platform includes a convex carrying base 12. Guiding tracks 11 are distributed close to and along the long sides the platform. The present embodiment includes four guiding tracks 11. An anti-slip element 121, such as sponge, anti-slip pad, and so on, is attached to the surface of carrying base 12, as shown in FIG. 3. Carrying base 12 is for contacting the placed portable electronic device. The convex design of the surface is to match the clamping sets 3. The directions of guiding tracks 11 originating from the center carrying base 12 are extending outwards towards the four corners of the platform. The trajectory of guiding tracks 11 has an arc shape. As shown in FIGS. 2, 3 and 4, each guiding track 11 includes guiding trench 111 penetrating support platform 1, concave positioning track 112 neighboring on both sides of guiding trench 111 and against inner wall of support platform, and tooth rack 113 formed on bottom surface of positioning track 112. Guiding trench 111 and positioning track 112 are for position adjustment set 2 to slide and rotate, and tooth rack 113 is provided for position locking after adjustment.
As shown in FIGS. 3 and 4, each position adjustment set 2 includes an arm 21 and a lock element 22. Arm 21 has a first end 211 and a second end 212, where first end 211 can slide and rotate on guiding track 11 for position adjustment. Lock element 22 is to fasten first end 211 of arm 21 to guiding track 11. Lock element 22 can be of any structure to fasten arm 21 to guiding track 11, for example, a bolt and a nut. Lock element 22 in the present embodiment includes an axial element 221, a brake element 222 and a wrench element 223. First end 211 of arm 21 has an axial hole 213 and a round slide block 214, as shown in FIG. 3. For assembly, round slide block 214 of arm 21 is placed inside positioning track 112. Axial element 221 passes, from top to bottom, axial hole 213, guiding trench 112, and brake element 222. Wrench element 223 is coupled to bottom end of axial element 221. Brake element 222 is not round, with terminating surface having teeth 2221 corresponding to tooth rack 113. When wrench element 223 is pulled to release, first end 211 of arm 21 slides inside guiding track 11 or rotates around axial 221. When wrench element 223 is pushed to lock, first end 211 of arm 21 is fastened to guiding track 11.
Clamping set 3 is installed to second end 212 of arm 21 of position adjustment set 2, and is for contacting side walls of the clamped portable electronic device. Clamping set 3 includes a fixing base 31 and a clamping element 32 installed on fixing base 31. Fixing base 31 is coupled to arm 21. The present embodiment uses screw 310 to couple fixing base 31 to arm 21; hence, fixing arm can rotate around arm 21. The purpose is to allow fixing base 31 rotate freely when clamping the portable device so that clamping element 32 can contact flatly with the side walls of the clamped portable device.
In the present embodiment, although clamping element 32 is attached to fixing base 31, clamping element 32 is allowed to move laterally for a brief distance for convenient placing and removing the portable device into and from the space formed by clamping sets 3.
As shown in FIG. 4, fixing base 31 is formed by two plates; for example, an upper cover 311 and a lower shell 312 forms a base with a hollow inside. The formed base includes an opening on a vertical surface for placing clamping element 32. Clamping element is L-shaped, including a vertical plate 321 and lateral plate 322. For assembly, later plate 322 is hidden inside fixing base 31. The space inside fixing base 31 matches the shape of lateral plate 322 so that lateral plate 322 can move laterally for a brief distance without disengaged from fixing base 31. Furthermore, fixing base 31 further includes a spring 33 inside, with two ends attached to lateral plate 322 and a protruding column 3121 inside fixing base. The force of spring 33 can pull vertical plate 321 tightly against the side wall of fixing base 3 without external force. In addition, an anti-slip pad 34 can be attached to surface of upper cover 311 to provide additional friction when contacting portable device as well as aesthetics.
Clamping element 32 can also be fixed to fixing base 31 in an unmovable manner. Because vertical plate 321 has a slight arc curve, a slight expansion resilience can be obtained when foam or anti-slip element is attached to the surface. Therefore, when all the position adjustment sets 2 are positioned and locked, a slight force must be applied to force vertical plates 321 expanding slightly outwards when placing the portable device into the apparatus until the portable device contacts carrying base 12. At this point, vertical plates 321 can restore their shape and position to clamp at the side wall of portable device. The same also applies to removing the portable device from the hold and support apparatus.
The following describes the usage scenarios of the apparatus of the present invention. FIG. 5 and FIG. 6 show schematic view of the hold and support apparatus of the present invention clamping portable devices of different sizes. As shown in FIG. 5, the dash-line drawing indicates the outline of a tablet 5. The first step is to place tablet 5 on carrying base 12 of support platform 1 and unlock lock element 22 of position adjustment set 2. Then, for each position adjustment set 2, the position of arm 21 on guiding track 11 is adjusted to move clamping element 3 on second end 212 close to side wall of tablet 5. During the close-in, fixing base 31 can rotate around arm 21 and finally clamping element 32 presses against side wall of tablet 5. When all four position adjustment sets 2 on guiding tracks 11 complete adjustment, each side wall of tablet 5 is contacted by two clamping elements 32, as shown in FIG. 5. The adjusted positions of position adjustment sets are applicable to a portable device. No additional adjustment is required for the subsequent placing and removal of the same portable device.
As shown in FIG. 6, the dash-line drawing indicates the outline of a smart phone 6. The first step is to place smart phone on carrying base 12 of support platform 1. Then, for each position adjustment set 2, the position of arm 21 on guiding track 11 is adjusted. Because the size of smart phone 6 is smaller, arm 21 must rotate a large angle, with initial position indicated by dash-line drawing. Fixing base 31 is preferably rotate around arm 21 prior to sliding arm 21 on guiding track 11 to move clamping element 3 close to side wall of smart phone 6. Then, lock element 22 is locked to fasten the position of arm 21 on guiding track 11. When all four position adjustment sets 2 on guiding tracks 11 complete adjustment, each side wall of smart phone 6 is contacted by two clamping elements 32, as shown in FIG. 6.
In summary, the present invention achieves position adjustment by sliding first end 211 of arm 21 of position adjustment set 2 on guiding track 11 and angle adjustment by rotating first end 211 of arm 21 of position adjustment set 2 on guiding track 11. Also, by changing the position of clamping set 3 on second end 212 of arm 21, the present invention allows different clamping sizes. In this manner, the hold and support apparatus of the present invention can clamp 3-16 inches portable electronic devices.
Furthermore, support platform 1 of the present invention can include three guiding tracks, three position adjustment sets and three clamping sets, as opposed to four in the previous embodiment. For arrangement, the guiding tracks are preferably distributed in the area surrounding the center part of the carrying base in an isometric manner, i.e., equal angles among each pair of guiding tracks.
Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
