Description

Technical Field

[0001] This utility model relates to a bracket, and more particularly to a controller-concealed stretchable bracket. Background Technology

[0002] Televisions are often used in conjunction with controllers (set-top boxes or routers, etc.). Currently, televisions are often wall-mounted, while the controller is usually placed separately on a table near the television. This results in a messy array of cables, affecting the overall aesthetics, and requires a tabletop to be placed under the television. Alternatively, a groove is cut into the wall to house the controller via a dedicated control box. However, the control box is exposed on the wall, which is unsightly. Therefore, many users have to cover the control box with pictures or furniture, which is detrimental to the overall wall aesthetics and makes controller repair and replacement difficult.

[0025] Example: A retractable, concealed controller bracket includes a controller mounting box 1 and a retractable, adjustable TV bracket 2 for mounting the TV to the front and rear. The controller mounting box 1 has an installation structure for mounting onto a building. The inner side of the controller mounting box 1 forms a space to accommodate the controller 3. The bottom surface of the controller mounting box 1 has several controller mounting holes for locking the controller 3. The fixed end of the TV bracket 2 is fixedly mounted on the controller mounting box 1. The mounting end of the TV bracket 2 has a TV mounting mechanism for fixing the TV.

[0026] The controller mounting box 1, used to install the controller 3, is combined with the TV bracket 2, which is adjustable in front and back position of the TV. This allows the controller 3 and the TV to be stacked on the wall, with the TV covering and hiding the controller mounting box 1. This avoids exposing the controller mounting box 1 on the wall and eliminates the need for other decorative items to cover it, thus improving the aesthetics of the interior decoration.

[0027] The controller mounting box 1 is an open-end box structure. The TV bracket 2 and the TV mounted on it can cover the opening of the controller mounting box 1 to hide the controller 3. The controller mounting box 1 adopts an open-end box structure. While the TV is used to block the view, the opening of the controller mounting box 1 can be opened by pulling out the TV, which facilitates the maintenance and replacement of the controller 3.

[0028] The television bracket 2 includes at least one set of front and rear telescopic mechanisms. Each front and rear telescopic mechanism includes a rear vertical support 21, a front vertical support 22, a first cross member 23, a second cross member 24, and a position holding mechanism. The rear vertical support 21 and the front vertical support 22, which extend vertically, are arranged parallel to each other and spaced apart. The rear vertical support 21 is fixedly installed in the controller mounting box 1. The first cross member 23 and the second cross member 24 are hinged together in the middle to form a scissor-like structure. The upper ends of the first cross member 23 and the second cross member 24 are respectively hinged to the upper ends of the rear vertical support 21 and the front vertical support 22, which can only rotate relative to each other. The lower ends of the first cross member 23 and the second cross member 24 are respectively hinged to the front vertical support 22 and the rear vertical support 21, which can slide up and down and can rotate relative to each other. The position holding mechanism can keep the first cross member 23 and the second cross member 24 stopped and positioned at any angle. The television mounting mechanism is installed on the front vertical support 22 of each set of front and rear telescopic mechanisms. By pushing and pulling the TV, the front vertical support 22 drives the first cross member 23 and the second cross member 24 to rotate, thereby realizing the forward and backward translation of the TV. This structure is simple, easy to operate, and low in cost. In addition, the TV bracket 2 can also adopt a multi-joint hinge structure to realize the forward and backward pushing and pulling to change the forward and backward position of the TV. This is an equivalent replacement structure that can be easily conceived by those skilled in the art based on this application, and it also falls within the protection scope of this application.

[0029] The front and rear telescopic mechanisms consist of two sets. The rear vertical supports 21 of each set are fixedly installed on both sides of the bottom surface of the controller mounting box 1 or on the two side walls extending vertically. The controller 3 is accommodated in the gap between the two sets of front and rear telescopic mechanisms. Using two sets of front and rear telescopic mechanisms can improve the stability of the television set. Furthermore, the two sets of front and rear telescopic mechanisms are symmetrically distributed on both sides inside the controller mounting box 1, and the space between the two sets of front and rear telescopic mechanisms is just enough to accommodate the controller 3, which helps to save space.

[0030] The television bracket 2 also includes a horizontal connecting plate 25. The first intersecting members 23 of the two sets of front and rear telescopic mechanisms are fixedly connected by the horizontal connecting plate 25 to form an integrated structure, or the second intersecting members 24 of the two sets of front and rear telescopic mechanisms are fixedly connected by the horizontal connecting plate 25 to form an integrated structure, or the first intersecting members 23 and the second intersecting members 24 of the two sets of front and rear telescopic mechanisms are respectively fixedly connected by the horizontal connecting plate 25 to form an integrated structure. The fixed connection of the corresponding intersecting members of the two sets of front and rear telescopic mechanisms by the horizontal connecting plate 25 enhances the stability of the overall structure. Furthermore, the horizontal connecting plate 25 is optimally positioned at the end of the intersecting member to avoid interference with the controller 3.

[0031] The rear vertical support 21, the front vertical support 22, the first cross member 23, and the second cross member 24 are all rods with a U-shaped cross section. The width of the first cross member 23 is greater than the width of the second cross member 24. A clearance hollow structure 231 is formed on the bottom surface of the U-shaped structure in the middle part of the first cross member 23. The second cross member 24 passes through the clearance hollow structure 231 in the middle of the first cross member 23. The length of the clearance hollow structure 231 allows the first cross member 23 and the second cross member 24 to rotate relative to each other within a set angle range. The upper and lower ends of the first cross member 23 are respectively inserted into the U-shaped openings of the rear vertical support 21 and the front vertical support 22. The upper and lower ends of the second cross member 24 are respectively inserted into the U-shaped openings of the front vertical support 22 and the rear vertical support 21. The sidewalls of at least one end of the first cross member 23 and the second cross member 24 are closely fitted with the sidewalls of the rear vertical support 21 and the front vertical support 22 to provide frictional resistance for relative movement. The rear vertical support 21, the front vertical support 22, the first cross member 23, and the second cross member 24 each adopt a U-shaped structure with different widths. They can be formed by sheet metal stamping and bending, resulting in low manufacturing cost and high strength. Furthermore, the cross members can be tightly fitted to the side walls of the hinged positions of the rear vertical support 21 and the front vertical support 22. For example, by using screws and washers to clamp and increase friction, the TV can be pushed or pulled to any position and then stopped. Of course, in addition to using frictional resistance to stop the TV at any forward or backward position, it can also be achieved by using a handle to tighten or by setting multiple locking points. This is an equivalent alternative structure that can be easily conceived by those skilled in the art based on this application, and it also falls within the protection scope of this application.

[0032] The television mounting mechanism includes a connecting plate 27 extending horizontally and a hook assembly 26 extending vertically. The connecting plate 27 is fixedly mounted on the front vertical support 22. The hook assembly includes a left hook 261, a right hook 262, a left locking piece 263, and a right locking piece 264. Both the left hook 261 and the right hook 262 are provided with a plurality of television connection holes 272 arranged vertically at intervals. The upper ends of both the left hook 261 and the right hook 262 form downward-facing upper hook bodies, and the lower ends of both the left hook 261 and the right hook 262 form L-shaped structures. The left locking piece 263 and the right locking piece 264 are respectively hinged to the left hook 261 and the right hook 262. At the lower end, the left locking plate 263 and the right locking plate 264 can rotate together with the L-shaped structure at the lower end of the left hook 261 and the right hook 262 to form an upward-facing lower hook body. The left locking plate 263 and the right locking plate 264 can maintain a locked state with the left hook 261 and the right hook 262 when rotated to the position forming the lower hook body. The upper hook body and the lower hook body of the hook assembly 26 can hook the upper and lower edges of the connecting plate 27 respectively, so that the hook assembly 26 can only slide left and right in the horizontal direction on the connecting plate 27. The left and right ends of the connecting plate 27 are also provided with blocking bending edges 271, and the hook assembly 26 stops between the blocking bending edges 271 at the left and right ends of the connecting plate 27. The television is installed on the left hook 261 and the right hook 262. Then, the left hook 261 and the right hook 262 are hung on the connecting plate 27. By rotating the locking plate, the lower ends of the left hook 261 and the right hook 262 are formed into lower hooks, so that the hook assembly 26 is stably hooked and connected to the connecting plate 27. The blocking bending edges 271 at both ends of the connecting plate 27 block the hook assembly 26, preventing it from sliding left and right and falling off.

[0033] The front vertical support 22 has threaded holes 221 at its upper and lower ends. There are two symmetrical connecting plates 27, each including a U-shaped connecting portion and a vertically extending hook mounting portion. The bottom surface of the U-shaped structure of the connecting portion has several horizontally spaced connecting holes 272. The two connecting plates 27 are connected by connecting screws, with any connecting hole 272 connected to the threaded holes 221 at the upper and lower ends of the front vertical support 22. The upper and lower hooks of the left hook 261 and right hook 262 respectively hook onto the hook mounting portions of the two connecting plates 27. The hook assembly 26 also includes an adjusting bolt 265. The upper and lower ends of the left hook 261 and right hook 262 are respectively provided with horizontal adjusting bends. The adjusting bolt is movably screwed onto the adjusting bends, and the end of the adjusting bolt abuts against the side wall of the U-shaped structure of the connecting portion of the two connecting plates 27. The adjusting bolt 265 allows for fine-tuning of the television height and simultaneously positions the hook assembly 26 on the connecting plate 27, preventing the hook assembly 26 from sliding arbitrarily.

[0034] The controller fixing box includes a square box 11 and a controller fixing plate 12. The square box 11 includes a square frame-shaped side wall, a baffle that bends vertically outward from the front edge of the side wall, and a crossbeam formed by multiple bends from the upper and lower edges of the rear end of the side wall. The crossbeam is provided with connecting screw holes 111, and screws can be screwed into the connecting screw holes 111. The upper end of the controller fixing plate 12 is provided with a gourd-shaped hole 121 with an upper diameter smaller than the lower diameter. The lower edge of the controller fixing plate 12 is provided with an opening groove 122 (U-shaped groove or V-shaped groove) with an open lower end. The screws screwed into the connecting screw holes 111 can be inserted into the gourd-shaped hole 121 and the opening groove. The controller mounting box 1 is composed of a square box 11 and a controller mounting plate 12. In use, the square box 11 can be embedded into the pre-made groove on the wall for fixing. Then, screws are tightened on the crossbeam of the square box 11. The controller mounting plate 12, which has been pre-installed with the controller 3, is then hung on the crossbeam through the gourd hole 121 and the opening slot 122. The screws are then tightened to achieve quick installation of the controller mounting plate 12 in the square box 11. This structure facilitates the installation of the controller 3.

[0035] The side wall of the square box 11 is also provided with fixing holes 112 for fixing and installing in the wall recess, and a breakable structure 113 for installing battery boxes and conduits of different sizes and models. The controller fixing plate 12 is provided with several heat dissipation holes 123. After the square box 11 is embedded in the wall, screws are driven into it through the fixing holes 112 on its side wall to fix the square box 11 in the wall and prevent it from falling off. At the same time, the breakable structure 113 on the side wall of the square box 11 can be broken according to the size and shape of the battery box and conduit to achieve matching installation and positioning of the battery box and conduit. The heat generated by the controller 3 can be quickly dissipated through the heat dissipation holes 123 on the controller fixing plate 12 to prevent the controller 3 from overheating and being damaged.
