Description

TECHNICAL FIELD

[0001] This application relates to display screen mounts, and more particularly to a wall mount display screen mount with adjustable height. BACKGROUND

[0002] Flat panel televisions, gaming displays, or other devices having a display screen are often mounted so that the center of the screen is level with the viewer's eye level. This is because the viewer can become uncomfortable if viewing a display screen that is significantly above or below eye level for an extended period of time. Despite this, many homes choose to mount the display screen on the wall above a fireplace, and the most common location is on the mantel that extends outward from the wall. When the display screen is mounted in this location, a viewer standing behind can see the display screen completely without any obstruction, but the screen is typically above eye level, especially for a seated viewer. For this reason, some display screen wall mounts include a linkage mechanism to lower the display screen and return the display screen to the storage position on the mantel. Such linkage mechanisms generally cause the display screen to be closer to the wall when the display screen is in the storage position above the mantel, and the linkage mechanisms cause the display screen to be farther from the wall when the display screen is lowered for viewing to avoid the display screen contacting the mantel.

[0003] The best viewing occurs when the display screen is viewed head on, i.e., on a line that is normal to the center of the display screen. The viewing is degraded once the optimal viewing position is deviated from. For example, the viewing is greatly degraded when the display screen is viewed at an angle to the side or at an angle to the top or bottom edge. To always ensure the best viewing, some display screen mounts allow the display screen to be rotated left and right and / or tilted up and down to reduce the angle from eye level.

[0004] Display screens come in a variety of sizes. The interface configuration of the display screen mount varies from manufacturer to manufacturer, from model to model, and over time. Therefore, it is desirable for a display screen mount to be able to support different sizes of display screens and to match different configurations of interfaces. The larger the size of the display screen, the greater the weight of the display screen. For large display screens, it is important to ensure that the mount is securely fastened to the wall. Therefore, it is desirable for a display screen mount to include alternative mounting brackets to allow heavier display screens to be mounted to different configurations of walls. Additionally, the heavier the display screen, the more difficult it is for a user to adjust the height of the display screen. For this reason, it is common for a display screen mount to include a counterbalance mechanism to reduce the force required to move the display screen. However, the weight of different display screens varies greatly, so it is desirable for the weight of such a counterbalance mechanism to be adjustable. Otherwise, if the load of the mount is too small, it will be difficult for a user to raise the display screen, and if the load of the mount is too great, it will be difficult for a user to lower the display screen.

[0005] In view of the above, there is a need for an innovative adjustable mount for a display screen for use above a fireplace to accommodate viewers in different locations and to accommodate display screens of different sizes, weights, and mount interface configurations. SUMMARY

[0006] In view of the above, the present application provides an adjustable mount for a display screen to solve the above technical problems.

[0015] the panel being movable relative to the bracket after being secured to the vertical surface to move a display screen connected to the panel upwardly or downwardly relative to the vertical surface;

[0016] wherein a force required to move the panel relative to the bracket depends on a position of the slide on the rail.

[0017] In another aspect, the present application includes an adjustable mount for a display screen for mounting the display screen on a selected vertical surface, the mount comprising:

[0018] a bracket, the bracket being anchored to the selected vertical surface;

[0019] an elongated upper link, the upper link being pivotably connected to the bracket;

[0045] Please refer to Figure 1 , Figure 1 This is a perspective view of an adjustable bracket for mounting a display screen on a wall, according to one embodiment of this application. Figure 1 As shown, the adjustable bracket 20 supports the display screen S, which may be, but is not limited to, a flat-screen TV, a gaming monitor, or other device with a screen. The adjustable bracket 20 mounts the display screen S onto a surface W, which may, for example, be a vertical wall, including the wall above a fireplace. Figure 2 As shown, the adjustable support 20 includes a bracket 22, a linkage mechanism 24 with a balance adjustment mechanism 26, and a display screen bracket 28. Please refer to the above description. Figure 3 In addition to the balance adjustment mechanism 26, the linkage mechanism 24 also includes an upper linkage 30, a gas spring 32, a pair of lower extension rods 34, a pivot plate 36 and an inclined plate 38.

[0046] like Figures 3-5As shown, the bracket 22 includes a wall-mounted plate 40 with side flanges 42 mounted on opposite sides, a pair of center flanges 44, and a pair of lower mating flanges 46. The wall-mounted plate 40 has mounting holes 48 for installing anchor bolts (not shown) at selected locations to secure the bracket 22 to the wall W. The side flanges 42 have a pair of spaced-apart upper mounting holes 50 for installing fastening components 52, thereby pivotally connecting the wall-mounted end 54 of the upper link 30 to the bracket 22. The center flanges 44 also have a pair of corresponding mounting holes 56 for installing fastening components 58, thereby pivotally connecting the wall-mounted end 60 of the gas spring 32 to the bracket 22 below the upper link 30. Each side flange 42 has a pair of lower mounting holes 62 aligned with the mounting holes 64 on the lower mating flanges 46. Fastening assembly 66 pivotally connects the wall-mounted ends 68 of each extension rod 34 to the lower mounting holes 62 and 64 as shown. The fastening assemblies 52, 58, and 66 shown in the figure each include a machine screw, a lock nut, and a washer, but the fastening assembly may also include other fastening elements. For example... Figure 4 and Figure 5 As shown, the triangular stop 70 is fixed to the side flange 42 below the wall-mounted end 68 of each extension rod 34 by conventional screw fasteners 72.

[0047] like Figure 5 and Figure 7 As shown, the balance adjustment mechanism 26 includes a main housing 80 and a slider 88. The main housing 80 includes a panel 82 with a rectangular strut 84. The rectangular strut 84 is connected to a pair of cylindrical vertical rods or guide rails 86. The slider 88 includes a pair of cylindrical openings 90, the size and orientation of which match the vertical guide rails 86 connected to the strut 84, allowing the slider 88 to move freely vertically along the guide rails 86. A pair of flanges 92 spaced apart extend from the slider 88 opposite the panel 82. Each flange 92 has a through hole 94 for mounting a fastening assembly 96, thereby pivotally connecting the viewing end 98 of the gas spring 32 to the slider 88. Side flanges 100 extend from each side of the panel 82. A pair of mating flanges 102 extend from the panel 82 below the strut 84. Each side flange 100 has an upper mounting hole 104 for mounting a fastening assembly 106, thereby pivotally connecting the viewing end 108 of the upper connecting rod 30 to the balance adjustment mechanism 26. Each side flange 100 also has a lower mounting hole 110. Please refer to both. Figure 8The lower mounting hole 110 is aligned with the corresponding mounting hole 112 in the mating flange 102. The fastening assembly 114 pivotally connects the viewing end 116 of each extension rod 34 to the lower mounting hole 110 and mounting hole 112 as shown. The bracket 22, upper connecting rod 30, panel 82, and lower extension rod 34 form a four-bar linkage, maintaining the relative angle between the bracket 22 and the panel 82 as the panel 82 moves up and down relative to the bracket 22 via the upper connecting rod 30 and lower extension rod 34. Threaded reinforcement members 118 are fixed to the struts 84 near each end of the guide rail 86. Please refer to [further details]. Figures 9A-9D The selected threaded key 120 can be installed on the reinforcement 118 to push the slider 88 along the guide rail 86 during the use of the support 20 and when the balance adjustment mechanism 26 bears the weight of the display screen. In the slider 88, a hardened insert 122 is installed at the contact point between the threaded key 120 and the slider 88 to prevent the threaded key 120 from scratching the slider 88 during rotation.

[0048] like Figure 5As shown, panel 82 includes a vertical slot 130. Clamp 132 is secured to slider 88 by screw fasteners 134 (machine screws). Slider 88 is clamped to panel 82 by tightening screw fasteners 134, thereby securing slider 88 to guide rail 86. Panel 82 has a scale 136, and clamp 132 has an indicator 138 to allow the user to determine the relative position of slider 88 to panel 82. A pair of brackets 140 extend from panel 82 below vertical slot 130 for mounting fastening components 142, thereby pivotally connecting pivot plate 36 to balance adjustment mechanism 26. Pivot plate 36 includes a pair of horizontal flanges 144. Mounting holes 146 are present in the horizontal flanges 144 for mounting fastening components 142, allowing pivot plate 36 to rotate freely about fastening components 142 relative to balance adjustment mechanism 26. Pivot plate 36 also includes opposite flanges 148. Each side flange 148 has an upper mounting hole 150 and a lower mounting hole 152. The tilting plate 38 includes opposing side flanges 154. Each side flange 154 of the tilting plate 38 has a lower mounting hole 156 for mounting a fastening assembly 158, thereby mounting the tilting plate 38 into the corresponding lower mounting hole 152 on the side flange 148 of the pivot plate 36, allowing the tilting plate 38 to selectively rotate relative to the pivot plate 36 about the lower mounting hole 156. Each side flange 154 of the tilting plate 38 also has an arcuate groove 160 above the lower mounting hole 156 for mounting the fastening assembly 162 to connect the tilting plate 38 to the pivot plate 36. The tilting plate 38 can rotate about the lower mounting hole 156 through the arcuate groove 160. A series of ridge-like protrusions 164 extend from the arcuate edges of each arcuate groove 160 to increase the friction between the side flange 154 of the inclined plate 38 and the fastening assembly 162, thereby preventing the fastening assembly 162 from loosening. Through the connection between the pivot plate 36 and the panel 82, the user can press... Figure 10A and Figure 10B As shown, rotate the display screen left and right. Figure 10A and Figure 10B In the process, through the connection between the pivot plate 36 and the panel 82, the display screen can rotate approximately 25° in each direction, but the connection between the pivot plate 36 and the panel 82 can be adjusted to allow the display screen to rotate at different angles. Through the connection between the tilt plate 38 and the pivot plate 36, the user can press... Figure 11A and Figure 11B As shown, the display screen tilts forward and backward. Figure 11B As shown, through the connection between the tilting plate 38 and the pivot plate 36, the user can tilt the top of the display screen forward by approximately 15°. Figure 11AAs shown, through the connection between the tilt plate 38 and the pivot plate 36, the user can tilt the top of the display screen backward by approximately 5°. However, the user can change the tilt angle range of the display screen by adjusting the connection between the tilt plate 38 and the pivot plate 36. Furthermore, the tilt plate 38 includes four inclined slots 166 for connecting the display screen bracket 28 to the tilt plate 38 via screw fasteners 168. With the aid of the inclined slots 166, the display screen bracket 28 can rotate relative to the tilt plate 38, bringing the display screen to a horizontal position. As shown, with the aid of the inclined slots 166, the display screen bracket 28 can rotate approximately 5° to each side. However, the user can change the rotation angle range of the display screen bracket 28 by adjusting the inclined slots 166.

[0049] like Figure 2 and Figure 6 As shown, the display screen bracket 28 includes a hook 170. The hook 170 includes an upper crossbar 172 and a lower crossbar 174. Vertical support members 176 of the display screen are suspended from the upper crossbar 172. Each vertical support member 176 has an opening 178 with a hook for hanging on the upper crossbar 172. Figure 6 and Figure 14 As shown, each vertical support member 176 also has a threaded hole 180 for installing a screw fastener 182 to secure it to the lower crossbar 174, preventing the hooked opening 178 in the vertical support member 176 from separating from the upper crossbar 172. The lower end of each vertical support member 176 is connected to a common horizontal member 184 to enhance the rigidity of the display screen bracket 28. Each vertical support member 176 has several openings 186 spaced at intervals for installing screw fasteners (not shown in the figure), thereby securing the vertical support member 176 to the display screen. Figure 2 and Figure 3 As shown, a handle assembly 188 is mounted on the horizontal member 184 by screw fasteners 192, and a handle 190 is mounted on the opposite side of the handle assembly 188. Figure 6 As shown, the handle assembly 188 has an elongated opening 194, allowing the handle assembly 188 to be adjusted vertically relative to the horizontal member 184 to accommodate displays of different sizes, such as... Figure 6 As shown. The handle assembly 188 has a handle 190 for the user to grip during the display tray 28.

[0050] like Figure 12As shown, through the bracket 20, the user can move the display screen to the high or storage positions indicated by the solid lines, in which the upper link 30, gas spring 32 and lower extension 34 extend upwardly from the bracket 22. Through the bracket 20, the user can also move the display screen to the lowest viewing position indicated by the dashed line, in which the extensions 34 contact the corresponding stops 70 (indicated by the dashed line). The bracket 20 is preferably mounted above and far enough from a mantel or other obstruction so that the extensions 34 are in sufficient contact with the stops 70 to prevent the extensions 34 from turning into the mantel. As shown in the figure, the upper link 30 can be rotated about 130° from the vertical, but the range of rotation of the display screen carriage 28 can be changed by adjusting the four-bar linkage and stops 70. Figure 12 As shown, during movement of the display screen away from the lowest viewing position, the display screen is carried away from the wall by the bracket 20. Thus, as the user lowers the bracket 22, the display screen can be extended below the mantel. The upper link 30 in the figure can be rotated about 130° from the vertical, but the range of rotation of the display screen carriage 28 can be changed by adjusting the four-bar linkage and stops 70.

[0051] Figure 13 An alternative mounting bracket system 200 is shown in place of the bracket 22. The system 200 includes a border 202. The border 202 has a plurality of openings 204 for anchoring the border to a wall of a structure using conventional anchors. For example, when the wall is composed of drywall covering wooden studs, the border 202 can be anchored to adjacent studs. The border 202 includes an upper clamping plate 206 and a lower strip 208, both of which cover the entire width of the border 202. In addition, the system 200 includes a bracket 210. The bracket 210 is similar to the bracket 22 described above, except that the bracket 210 has a hook 212 at its upper edge. After the border 202 is anchored to the wall, the hook 212 on the bracket 210 will hang from the clamping plate 206. The lower strip 208 has a plurality of threaded holes 214 for mounting fasteners 216 to secure the bracket 210 in place. Through the threaded holes 214, the user can mount the bracket 210 at different horizontal positions along the border 202. Thus, the border 202 can be mounted horizontally to the wall so that the bracket is securely mounted to the wall. The bracket 210 can be mounted horizontally to the border 202 so that the bracket 210 is centered at a location such as a mantel.

[0052] After the bracket 20 is mounted to the wall, the display screen is mounted to the bracket 20. The vertical support member 176 of the display screen carriage 28 is secured to the back of the display screen. After the vertical support member 176 is secured to the display screen, the horizontal member 184 Figure 2 ) is mounted to the vertical support member 176 and the handle assembly 188 is mounted to the horizontal member 184. After the vertical support member 176 is secured to the display screen, the user can adjust the height of the display screen by adjusting the length of the gas spring 32. The user can also adjust the horizontal position of the display screen by adjusting the horizontal position of the bracket 210 along the border 202. Figure 14The position of the display screen is adjusted so that the opening 178 in the vertical support member 176 hooks over the upper crossbar 172 on the stand 20. After the opening 178 in the vertical support member 176 hooks over the upper crossbar 172 on the stand 20, the display screen can be rotated on the lower crossbar 174. The mounting screw fastener 182 is tightened to secure the display screen to the hook 170.

[0053] After the stand 20 is secured to the wall W and the display screen S is mounted on the stand 20, the user can adjust the counterbalance adjustment mechanism 26 by means of the key 120 to easily move the stand 20 to any position between the storage position and the lowest viewing position. To adjust the counterbalance adjustment mechanism 26, the key 120 is simply turned into the corresponding threaded fastener 118 on the brace 84, and then the key 120 is turned to slide the slide 88 along the rail 86. The key 120 can be turned into the upper fastener 118 to slide the slide 88 to the lowest position on the rail 86, as shown in Figure 15A The key 120 can also be turned into the lower fastener to slide the slide 88 to the highest position on the rail 86, as shown in Figure 15B When the slide 88 is in the lowest position on the rail 86, the load on the gas spring 32 is the least. When the slide 88 is in the highest position on the rail 86, the load on the gas spring 32 is the greatest, and the force required to raise the display screen is the least. After the proper load balance is achieved, the key 120 is removed, and the screw fastener 134 is tightened to secure the counterbalance adjustment mechanism 26 in place.
