## Title
Low profile mount for flat panel electronic display

## Abstract

A low-profile mount for a flat panel electronic display that is selectively shiftable between a wall-confronting position wherein the back of the flat panel electronic display is disposed parallel and proximate to the wall surface and a tilt position wherein the top of the display is tilted away from the wall surface. The mount is configured so that points spaced apart forwardly from display receiving surfaces of the mount are shifted along a substantially horizontal axis as the mount is shifted between the wall confronting position and the tilt position. Advantageously, the display can be attached to the mount so that the points are horizontally registered with a center of gravity of the display such that the display is self-balancing at any point along the travel between the wall confronting position and the tilt position.

## Background
RELATED APPLICATIONS
The application claims the benefit of U.S. Provisional Application No. 61/093,676, entitled LOW PROFILE MOUNT FOR FLAT-PANEL ELECTRONIC DISPLAY, filed Sep. 2, 2008, said application being hereby fully incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates to electronic displays and more specifically to mounts for electronic displays.
BACKGROUND OF THE INVENTION
An attribute of modern flat-panel electronic displays that makes them highly desirable to consumers is the aesthetic appeal of a very flat device that has the appearance of a framed photo or painting when hung from a wall. This same attribute is also desirable in that floor and interior space taken up under the display is minimal.
Mounting devices have been developed for flat-panel electronic displays that enable the display to be mounted very close to the wall. These prior mounting devices, however, have drawbacks.
One drawback of prior low-profile mounting devices is that they generally do not enable access to the rear of the display for the connection of cables and wires once the display is in place on the mount. Instead, the installer must wrestle with a sometimes heavy and awkward display device to connect the wires before mounting on the wall. Further, the wires may then interfere with attachment to the wall once connected.
Another drawback to prior low-profile display mounts is that they often do not provide secure attachment to the wall so as to prevent inadvertent detachment of the display. In one such prior mount, a simple hook arrangement is used at the top of the device, with a strip of hook- and loop material below to hold the device in place. If the bottom of the display is pulled away from the wall slightly, the hook-and-loop material disengages and enables disengagement of the top hook, leading to the display falling onto the floor.
A further drawback of many prior low-profile display mounting devices is that they are awkward and difficult to manipulate. An installer attempting to mount the display device may have to lift a heavy or large size display into an awkward position in order to attach the device to a wall mount, or may have to manipulate complicated catches or latching devices while simultaneously lifting.
Another drawback of previous low profile mounts is that they represent a compromise between closeness of the display to the wall surface and the range of tilting motion available for the display. If the mount has a very low profile, the tilt range of the mount is limited because the edge of the display contacts the wall when tilting. If the mount is made thicker to accommodate the tilt motion of the display, the desirable aesthetic of a display mounted close to the wall surface is lost.
Accordingly, what is still needed in the industry is a low-profile electronic display mounting device that overcomes these drawbacks.
SUMMARY OF THE INVENTION
Embodiments of the present invention provide a low-profile display mount that overcomes the drawbacks of the prior art. According to embodiments of the invention, a display mount includes a wall interface plate, and one or more tilt assemblies. Each tilt assembly presents a display receiving surface for receiving the back side of the display thereon. The tilt assemblies are shiftable between a wall confronting position wherein the back side of the display is proximate and substantially parallel with the wall surface, and a tilt position wherein the top of the display is tilted away from the wall. The tilt assemblies are configured so that points spaced apart forwardly of the display receiving surfaces translate along a substantially horizontal axis as the tilt assemblies are shifted between the wall confronting position and the tilt position. Advantageously, the display can be attached to the mount so that the points are horizontally registered with a center of gravity of the display such that the display is self-balancing at any point along the travel between the wall confronting position and the tilt position. The mount may enable the back side of the display to be spaced apart between only about 0.25 to 0.50 inch, and preferably 0.30 inch, from the wall when in the wall confronting position, while still enabling tilt positioning of the display.
According to an embodiment, an electronic display system includes a flat panel electronic display and a mount for attaching the flat panel electronic display to a substantially vertical wall surface. The mount includes a wall interface adapted to attach to the wall surface and a pair of tilt assemblies. Each tilt assembly includes a hook bracket for engaging the wall interface, a display interface presenting a display receiving surface for receiving the flat panel electronic display, and a scissors assembly operably coupling the hook bracket and the display interface. The tilt assemblies are coupled to a rear side of the flat panel electronic display and are selectively shiftable between a wall confronting position wherein the rear side of the flat panel electronic display is substantially parallel and proximate to the wall, and a tilt position wherein the top of the flat panel electronic display is tilted away from the wall. The scissors assembly is configured so that a point forward of the display receiving surface and horizontally registered with a center of gravity of the flat panel electronic display translates substantially horizontally as the tilt assembly is shifted between the wall confronting position and the tilt position. In some embodiments, the scissors assembly includes a first arm assembly and a second arm assembly presenting a pair of opposing ends. The first arm assembly is pivotally coupled with the second arm assembly intermediate the opposing ends of the second arm assembly. The first arm assembly may include a pair of parallel rails and the second arm assembly may also include a pair of parallel rails. The first arm assembly may be pivotally coupled to the wall interface and slidably coupled to the display interface, and the second arm assembly may be pivotally coupled to the display interface and slidably coupled to the wall interface. In some embodiments, the pivotal coupling of the first arm assembly to the wall interface is disposed above the slidable coupling of the second arm assembly to the wall interface. Each tilt assembly may further include a kickstand assembly. If so equipped, the flat panel electronic display may be selectively shiftable to a third position enabling access to the back side of the flat panel electronic display wherein the top of the flat panel electronic display is proximate the wall surface and the bottom of the flat panel electronic display is spaced apart from the wall surface, the kickstand assembly including a kickstand for contacting the wall surface to maintain the flat panel electronic display in the third position.

Upper pivot axle 90 is retained in position with nut 92.
As depicted in FIG. 16, hook bracket 40 generally includes planar central portion 94 with inwardly projecting flanges 96, 98, at each lateral margin. Hooks 100, 102, are defined at the upper ends 104, 106, of each flange 96, 98, respectively.
Latch assembly 42, as depicted in FIG. 5, generally includes body 108 and latch 110. Latch 110 is pivotally attached to body 108 with pivot fastener 112 and nut 114. Hook plate 116 extends between rails 118, 120, of body 108 at the upper end thereof.
Kickstand assembly 46 generally includes kickstand 122, axle 124, and pull handle 126. Loop 130 of pull handle 126 is received in notch 132 in inner end 134 of kickstand 122. As depicted in FIGS. 2 and 3, kickstand 122 is pivotally coupled at bottom end 136 of hook bracket 40, with axle 124 extending through apertures 138. Spacers 140 are disposed between lateral walls 142 of kickstand 122 and hook bracket 40. Axle 124 is retained with nut 144.
As depicted in FIGS. 2 and 3, latch assembly 42 is attached to hook bracket 40 with fasteners 146, 148, extending through apertures 150, 152. Display interface catch 154 is attached to hook bracket 40 just below latch assembly 42 with fastener 156.
Display interface 48, as depicted in FIG. 17, generally includes planar central portion 158 with rearwardly projecting flanges 160, 162, at each lateral margin. Track portion 163 is defined intermediate the ends of display interface 48 by flanges 164, 166, extending inwardly from flanges 160, 162, respectively. Central portion 158 defines a plurality of apertures 168 for receiving fasteners to attach a flat panel display to display receiving surface 170.
Display interface 48 is coupled to hook bracket 40 with scissors assembly 44. Outer arm assembly is pivotally attached to display interface 48 with fasteners 172, 174, extending through apertures in display interface 48. Pivot block 54 is attached to hook bracket 40 with fasteners 176 through apertures 178. Rollers 70, 72, are rollably received behind inwardly extending flanges 96, 98, of hook bracket 40, while slide blocks 86, 88, are slidably received in track portion 163 of display interface 48 behind flanges 164, 166.
In use, each of tilt assemblies 24 is attached to a rear side of flat panel display 180, with fasteners (not depicted) through apertures 168. It will be appreciated that the plurality of apertures 168 enables tilt assemblies 24 to be attached at any desired vertical position on display 180. Further, tilt assemblies 180 may be spaced apart any distance W as desired, limited only by the location of fastener receiving locations on display 180.
Wall interface plate 22 is attached to a wall 182 in a generally horizontal orientation as depicted in FIGS. 1 and 2. Hooks 100, 102, of hook brackets 40 are hooked over upper lip 28, with hook plate 116 also extending behind upper lip 28, as depicted in FIGS. 10 and 11. Latches 110 can then be pivoted about pivot fasteners 112 in the direction of the arrow as depicted in FIG. 10, so that latch ends 184 extend behind lower lip 30, thereby securely latching tilt assemblies 24 to wall interface plate 22.
With tilt assemblies 24 latched to wall interface plate 22, display 180 is securely hung on wall 182. An installer can then simply grasp the lower edge 186 of display 180 and pull outward to deploy kickstands 122. As lower edge 186 is pulled outward, kickstands 122 fold out from hook bracket 40 by gravity and contact wall 182 such that the lower edge 186 of display 180 is held away from wall 182 as depicted in FIG. 14, thereby providing space for connecting wires and cables to display 180 while the display 180 is attached to wall 182. Notably hooks 100, 102, are relieved slightly to enable this pivoting of hook bracket 40 about upper lip 28 without binding. Hook plates 116 of latch assemblies 42 remains snugly engaged behind upper lip 28 to prevent inadvertent disengagement of tilt assemblies 42 from wall interface plate 22.
Once the connection of wires and cables is complete, an installer may lift lower edge 186 of display 180 outward slightly, and pull downward on pull handles 126, causing kickstands 122 to pivot upwards adjacent hook brackets 40. Lower edge 186 of display 180 can then be allowed to swing inward adjacent wall 186 so that the mount and display are positioned in a vertical wall-confronting position as depicted in FIG. 12. Removal is the reverse of installation.
Advantageously, tilt assemblies 24 and wall interface plate 22 may be made with a very small total depth dimension, enabling very close mounting of the back side of display 180 to wall 182. In preferred embodiments, the back of display 180 may be as close as 0.25 to 0.50 inch to wall 182 when in the wall confronting position. In some further preferred embodiments, back of display 180 may be about 0.30 inch from wall surface 180 when in the wall confronting position.
The scissors assembly 44 of each tilt assembly 24 functions to enable display 180 to be selectively tilted outward from wall 182 as desired. As upper edge 188 of display 180 is pulled outward away from wall 182, outer arm assembly 50 pivots about fasteners 172, 174, while inner arm assembly pivots on upper pivot axle 90. Rollers 70 ride upward behind inwardly extending flanges 96, 98, of hook bracket 40, while slide blocks 86, 88, are slide upward in track portion 163 of display interface 48 behind flanges 164, 166.
Those of skill will appreciate that the geometry of scissors assemblies 44 may be configured, by adjusting the length of rails 56, 58, 74, 76, and the positions of the pivots and slides, such that the lower edge 186 of display 180 shifts upward and away from wall 182 as the display 180 is tilted about a tilt axis T located forward of and below the display 180, between the more vertical position depicted in FIG. 12 and the tilted position depicted in FIG. 13. Further, a point disposed forwardly from display receiving surface 170, and preferably horizontally registered with a center of gravity C.G. of display 180, may translate substantially horizontally along an axis 190. This enables the display 180 is to self-balance at any position along its travel from the wall confronting position of FIG. 12 and the fully tilted position of FIG. 13, without the need to introduce further friction or retaining mechanisms into tilt assemblies 24. Further details and configurations of wall avoiding self balancing display mounts are disclosed in PCT International Application No. PCT/US2008/000117, assigned to the owners of the present invention and hereby fully incorporated herein by reference.
The embodiments above are intended to be illustrative and not limiting. Additional embodiments are encompassed within the scope of the claims. Although the present invention has been described with reference to particular embodiments, those skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention. For purposes of interpreting the claims for the present invention, it is expressly intended that the provisions of Section 112, sixth paragraph of 35 U.S.C. are not to be invoked unless the specific terms “means for” or “step for” are recited in a claim.
