[0001] Related Applications

[0002] This application claims the benefit of U.S. Provisional Application No. 63 / 617,543, filed on January 4, 2024, entitled "TELEVISION MOUNT WITH HANDLE-OPERABLE HEIGHT ADJUSTMENT", the entire content of which is hereby incorporated by reference in its entirety. Technical Field

[0003] The present invention relates to mounting devices for televisions, and more particularly, to mounting devices for attaching flat panel televisions and related equipment to a wall. Background Art

[0004] As flat panel televisions and monitors have become increasingly popular, there has been a growing need to mount them to a wall to avoid using furniture to support the equipment, which would take up floor space. Additionally, for optimal viewing, sound, and aesthetic reasons, it is often desirable to more precisely position the television. For these purposes, various types of mounting devices have been developed. For example, U.S. Patent No. 8,693,172 discloses a full-motion mounting device for attaching a television to a wall, which is owned by the assignee of the present invention and is hereby incorporated by reference in its entirety. This mounting device enables the television to tilt, pivot left and right, and move closer to or farther away from the wall as needed.

[0005] However, a disadvantage of existing full-motion television mounting devices is that vertical height adjustment of the television can only be achieved when the television is attached to the mounting device. This is typically accomplished through two separate adjustments. This results in additional installation time and limits the flexibility of installation.

[0006] What is needed is a full-motion television mounting device that addresses the disadvantages of existing mounting devices. Summary of the Invention

[0038] Although the various embodiments can be modified into various modifications and alternative forms, the details of the various embodiments have been shown by way of example in the drawings and will be described in detail. However, it should be understood that the intention is not to limit the claimed invention to the specific embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the subject matter defined by the claims. Detailed Embodiments

[0039] Figure 1 The television installation device 20 according to an embodiment of the present invention is depicted in Figure 1 . The installation device 20 generally includes a display screen engaging assembly 22, an arm assembly 23 including articulated swing arms 24, 26, and a wall engaging assembly 28. It will be understood that the articulated swing arms 24, 26 can be replaced with any suitable arm assembly, such as a one-piece single arm or a single articulated arm, while still remaining within the scope of the present invention. For a non-limiting example, the arm assembly 23 can be replaced with a scissor extension mechanism, such as the scissor extension mechanism disclosed in U.S. Patent No. 8,508,918 owned by the owner of the present application and hereby incorporated by reference in its entirety.

[0040] As Figure 2 depicted in Figure 2 , the display screen engaging assembly 22 generally includes a height adjustment assembly 30 and a display screen attachment assembly 31 in the form of cross bars 32, 34 and upright columns 36, 38. As Figure 5As depicted in the exploded view, the height adjustment assembly 30 generally includes an elongate guide 39 in the form of a guide channel 40, an adjustment screw 42, a carrier assembly 44, a telescoping handle 46, and bushing assemblies 48, 50. The bushing assembly 48 generally includes a bushing 52 and a retaining clamp 54, and the bushing assembly 50 generally includes a bushing 53 and a retaining clamp 55. The bottom end portion 56 of the adjustment screw 42 is rotatably received in the bushing 52, and the top end portion 58 of the adjustment screw 42 is rotatably received in the bushing 53 such that the adjustment screw can rotate relative to the guide channel 40 but not translate relative to the guide channel 40. Each of the bushing assemblies 48, 50 is fixed to the guide channel 40 by retaining clamps 54, 55, respectively. The adjustment screw 42 is also rotatably held on the guide channel 40 by a clamp 60.

[0041] The adjustment screw 42 is hollow and has a longitudinal bore 62. The shaft 64 of the handle 46 is selectively slidably received in the longitudinal bore 62. The handle 46 also includes a grip portion 66 fixed to the shaft 64 by a fastener 68. Although the shaft 64 is capable of longitudinal sliding in the adjustment screw 42, the shaft 64 is fixed to the adjustment screw 42 in terms of rotation such that rotation of the grip portion 66 causes rotation of the adjustment screw 42 in the bushings 52, 53. It will be understood that the handle 46 may be omitted and the adjustment screw 42 is driven by any other suitable means such as, by way of non-limiting example, a hex bolt head, an Allen head, or other connecting member capable of receiving a tool to apply rotation.

[0042] As Figure 6 As depicted in the partial exploded view, the carrier assembly 44 generally includes a housing 70, a nut 72, a latch 74, a biasing spring 76, and a landing pad 78. The housing 70 has laterally projecting flanges 80, 82, spring receiving tabs 84, a tongue 86, and the housing 70 defines apertures 88, 90. The landing pad 78 is received under the tongue 86.

[0043] The adjustment screw 42 has an external thread 92 that mates with an internal thread (not depicted) of the nut 72 such that when the adjustment screw 42 is rotated counterclockwise or clockwise, the nut 72 travels up and down the length of the adjustment screw 42, respectively. The nut 72 is fixed to the housing 70 by a fastener 94 received in an aperture 96. Although not depicted, another fastener may fix the housing 70 to the nut 72 on the opposite side.

[0044] Latch 74 generally includes projecting hook portions 98, 100 that extend through elongated apertures 88, 90, respectively. The latch 74 is resiliently fixed to the housing 70 by a biasing spring 76 that extends between a spring receiving tab 84 and a tab 102. Although not depicted, an additional biasing spring may be provided on the other side of the latch 74 and the additional biasing spring will be coupled in a similar manner. The biasing spring 76 biases the latch 74 upwardly within the housing 70. A pull strap 104 is coupled to the latch 74 to enable the latch 74 to be pulled downwardly against the bias of the biasing spring 76, thereby moving the hook portions 98, 100 downwardly within the apertures 88, 90.

[0045] As Figure 4 , Figure 6 and Figure 7 depicted in, the guide channel 40 has a back plate 106 and C-shaped side portions 108, 110 such that the guide channel 40 has a C-shaped cross-section. As Figure 4 and Figure 8 depicted in, the housing 70 includes bushings 112, 114. Each bushing 112, 114 has a slot 116 that enables the bushings 112, 114 to be respectively fitted onto flanges 80, 82 of the housing 70. The bushings 112, 114 are fitted into the C-shaped side portions 108, 110 such that the housing 70 can slide smoothly within the guide channel 40.

[0046] As Figure 9 depicted in, the articulated swing arms 24, 26 are pivotally coupled to the wall plate 28 at the connector portion and are pivotally coupled to the tilt head assembly 124 at the distal ends 120, 122. As Figures 9 to 11 depicted in, the tilt head assembly 124 generally includes a receiving / guiding bracket 126, bearing plates 128, 130, guide followers 132, 134 and arm connection brackets 136, 138. The receiving / guiding bracket 126 is generally U-shaped to form a forward-facing recess 140. Each of the side walls 142, 144 defines a pair of guide slots 146, 148 and 150, 152, respectively. The followers 154, 156 extend through the guide slots 146, 148, respectively, and are capable of sliding or rolling within the guide slots 146, 148. The followers 154, 156 are carried by the bearing plate 128. The followers 158, 160 extend through the guide slots 150, 152, respectively, and are capable of sliding or rolling within the guide slots 150, 152. The followers 158, 160 are carried by the bearing plate 130. The follower 160 is threaded and receives a friction knob 162 to enable the follower 160 to be tightened or loosened, thereby increasing or removing the frictional resistance to movement of the follower within the guide slot.

[0047] The guide slots 146, 148, 150, 152 can be configured to define a virtual horizontal tilt axis X-X as depicted in Figure 12 which is positioned in front at a distance Y from the display screen engaging member 22. The virtual tilt axis X-X passing through the attached display screen 184 enables the display screen 184 attached to the display screen engaging member 22 to maintain an inclined position without adding excessive friction via the friction knob 162, thereby improving usability. It will be understood that the guide slots 146, 148, 150, 152 can be curved, straight, or of any other shape that contributes to the desired effect while remaining within the scope of the present invention.

[0048] As Figure 14 depicted in the example of, the guide slots 146, 148, 150, 152 can be disposed along the circumference of a circle 147 having a center 149 that coincides with the virtual axis X-X. As depicted in the right side partial view thereof, the guide slots 150, 152 are symmetric, and their radii of curvature are centered on the center 149. The guide slots 150, 152 will allow the followers 158, 160 to slide thereon, enabling the receiving / guiding brackets 126, the uprights 36, 38, and the attached display screen 184 to tilt about the virtual tilt axis X-X, which will remain stationary.

[0049] In Figures 15 to 17 other examples of different slot configurations are depicted. In Figure 15 and Figure 15A the guide slots 150, 152 are arcuate, but have different lengths and are not symmetrically arranged. With such a configuration as depicted in Figure 15A the receiving / guiding brackets 126, the uprights 36, 38, and the attached display screen 184 will tilt about an instantaneous center according to well-known principles of machine kinematics. The followers 158, 160 are positioned a fixed distance apart and are substantially fixed in place relative to the carrier plates 128, 130 and the articulated swing arms 24, 26. Thus, the instantaneous center of the tilting motion of the receiving / guiding bracket 126 will be located within the tilting motion range of the receiving / guiding bracket 126 along a line 186 perpendicular to the midpoint of the line 188 drawn between the relative positions of the followers 158, 160 in the guide slots 150, 152. As Figure 15 depicted in, the region 190 where the lines 186 intersect will mark the approximate location of the instantaneous center. The virtual tilt axis X-X can be conceived as continuously shifting during the tilting motion of the receiving / guiding bracket 126 and being located at a point within the region 190.

[0050] Similarly, Figure 16 straight guide slots 150, 152 are depicted, and Figure 17depicts arcuate guide slots 150, 152, but curved in a direction opposite to that of the Figure 14 guide slots 150, 152. In these cases, the receiving / guiding bracket 126 will tilt about an instantaneous center disposed within region 190.

[0051] Accordingly, it will be understood that the guide slots 146, 148, 150, 152 can be of almost any shape or geometry that effectuates the tilting movement of the receiving / guiding bracket 126 about the virtual tilting axis X-X, and that this virtual tilting axis X-X can be achieved by shifting the instantaneous center. It will further be understood that the geometry of the guide slots 146, 148, 150, 152 can be such as to provide a greater or lesser tilting range (e.g., 5 degrees to 15 degrees) at the top of the display screen engaging member 22 relative to the bottom.

[0052] As Figure 2 and Figure 13 depicted, the positions of the posts 36, 38 of the display screen engaging member 22 can be shifted along the crossbars 32, 34 to accommodate the attachment hole pitch of display screens of different widths W. To shift the posts 36, 38, the fasteners 164 can be loosened, the posts 36, 38 can be slid to the desired positions on the crossbars 32, 34, and the fasteners 164 can be retightened. Marks 166 (e.g., 200 mm, 300 mm, 400 mm, etc.) can be provided on the crossbars 32, 34 to enable easy positioning to match the VESA pattern of the holes on the display screen.

[0053] As Figure 3 depicted, the display screen engaging member 22 is detachably coupled to the tilting head assembly 124. To effectuate the coupling, the housing 70 is pushed into the recess 140, and the tongue 86 is hooked onto the top edge 168 of the receiving / guiding bracket 126. The hooked portions 98, 100 of the latch 74 will engage in the apertures 170, 172 defined in the receiving / guiding bracket 126 and be pulled upward by the biasing spring 76 to latch the display screen engaging member 22 in place. The display screen engaging member 22 can be disengaged by pulling the strap 104 downward to move the latch 74 downward against the bias of the biasing spring 76 and lifting the display screen engaging member 22 and the attached display screen upward to disengage the tongue 86 from the top edge 168 of the receiving / guiding bracket 126.

[0054] In use, the wall bracket 28 with the attachment arms 24, 26 and the tilt head assembly 124 can be attached to a wall using suitable fasteners (not depicted) passing through the apertures 180. The display screen engagement member 22 can be adjusted for a suitable width W as described above and attached to the rear of an electronic display screen 184, such as a television or a monitor, using fasteners (not depicted) passing through the apertures 182 in the uprights 36, 38. Then, the display screen engagement member 22 and the display screen can be coupled to the tilt head assembly 124 in the same manner as described above. Then, the height of the television or monitor and the display screen engagement member 22 can be adjusted relative to the floor and the remainder of the mounting device 20 by pulling down on the gripping portion 66 of the handle 46 to extend the shaft 64 from the adjustment screw 42. Then, the gripping portion 66 can be rotated, which, due to the connection between the shaft 64 and the adjustment screw 42, will cause the adjustment screw 42 to rotate. Due to the threaded engagement of the nut 72 with the adjustment screw 42, the adjustment screw 42 and the elongate guide 39 will translate up or down relative to the carrier assembly 44 depending on the direction of rotation. Once at the desired height position relative to the floor, the gripping portion 66 and the shaft 64 can be slid back into the adjustment screw 42 to be hidden.

[0055] Accordingly, the described embodiments provide a convenient method for adjusting the height of a wall-mounted television or monitor near the floor with a single adjustment. The solution can be applicable to any mounting device, regardless of whether the mounting device is provided with an arm assembly capable of pivoting and regardless of whether the mounting device is provided with a tilting function.
