Description

CROSS-REFERENCE TO RELATED APPLICATION

This Non-Provisional Patent Application claims the benefit of the filing date of U.S. Provisional Patent Application Ser. No. 61/011,022 filed Jan. 14, 2008, entitled “LOW-PROFILE FLAT PANEL DISPLAY MOUNT.”

BACKGROUND

Panel displays include a display and a display mounting device configured to secure the display to a surface. Displays include information panels, televisions, and/or monitors. Recently, flat panel displays have been developed having a space-saving depth of only a few inches and designed to be attractively mounted on a wall in a home or an office. The known display mounting devices employed to mount these flat panel displays are inconsistent with the space-saving design, and often have a thickness that is greater than the thickness of the flat panel display. In addition, to the limited degree that the conventional display mounting devices are adjustable, the adjustability is achieved at the expense of bulky mechanisms that further increase the thickness of the mounting devices.
For these and other reasons, there is a need for the present invention.

SUMMARY

One aspect provides a display mounting device including a wall mount assembly attachable to a surface, and a panel mount assembly coupled to the wall mount assembly and attachable to a display. The panel mount assembly is movable relative to the wall mount assembly, and movement of the panel mount assembly relative to the wall mount assembly includes movement of at least one shaft subject to a differential braking torque.
One aspect provides a display mounting device including a wall mount assembly attachable to a surface, a panel mount assembly attachable to a display, the panel mount assembly including a tilting shaft configured to tilt the display, and a link arm assembly coupled between the wall mount assembly and the panel mount assembly.

DETAILED DESCRIPTION

In the following Detailed Description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” “leading,” “trailing,” etc., is used with reference to the orientation of the Figure(s) being described. Because components of embodiments can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.
It is to be understood that the features of the various exemplary embodiments described herein may be combined with each other, unless specifically noted otherwise.
In this specification, the phrase “degrees of freedom” means the set of independent displacements and/or rotations that specify the displacement or position or orientation of a body. A body that moves in three-dimensional space may have three translational degrees of freedom and three rotational degrees of freedom for a total of six degrees of freedom. Translation is movement without rotation, while rotation is angular motion about an axis.
The following definitions are taken relative to a wall defining an X-Y plane, with the X-axis oriented horizontally and the Y-axis oriented vertically, with a Z-axis extending out of the X-Y plane away from the wall:
In this specification, tilt means rotational movement about the X-axis. Tilt has the same meaning as pitch in nautical/mechanical terms.
In this specification, pan means rotational movement about the Y-axis. Pan has the same meaning as yaw in nautical/mechanical terms.
Tilt and pan are rotational movements.
In this specification, swing means movement along the X-axis (e.g., movement left and right). Swing has the same meaning as sway in nautical/mechanical terms.
In this specification, telescope means movement along the Z-axis (e.g., movement forward and backward). Telescope has the same meaning as surge in nautical/mechanical terms.
Swing and telescope are translational movements.
In this specification, torque means a force employed to rotate an object. Torque is analogous to the force employed to twist a shaft.
In this specification, braking torque means a resistance force impeding rotation of an object.
In this specification, differential braking torque is defined to be a non-zero difference between the braking torque for an object rotating in a first direction relative to the braking torque for the object rotating in a second direction. For example, differential braking torque means that the braking torque for a shaft rotating clockwise is different than the braking torque for the shaft when it is rotating counter-clockwise.
In this specification, full range of motion for a display mounting device is defined to include at least four degrees of freedom including tilt, swing, pan, and telescope degrees of freedom.
FIG. 1 is a perspective view of a display assembly 10 according to one embodiment. Display assembly 10 includes a display 12 coupled to a display mounting device 14, where the display mounting device 14 is configured for attachment to surface, such as a wall W, for example, by any form of suitable connectors 16.
The display mounting device 14 includes shafts connected between panels that combine to enable the display 12 to be moved away from and be tilted/extended from the wall W at nearly any desired orientation, for example, through a combination of movements about (or relative to) shafts 28 and a tilting shaft 42. In one embodiment, at least one of the shafts 28, 42 is subject to a differential braking torque that allows even large and heavy displays 12 to be selectively positioned in a desired orientation relative to wall W.
The display 12 includes electronic displays and non-electronic displays, such as photographs, paintings, and artwork. In one embodiment, the display 12 is an electronic display, such as a television, a computer monitor, or other information display. In one embodiment, the display 12 is a 50 inch Pro-101FD flat panel display that is about 9 mm thick and available from Pioneer Electronics, Tokyo, Japan. In general, larger displays will be heavier. The display mounting device 14 enables the controlled movement and placement of heavy/large displays away from walls to which the displays are attached.
FIG. 2 is a perspective view of the display mounting device 14 according to one embodiment. The display mounting device 14 includes a wall mounting assembly 20 that is attachable to a wall or other surface by connectors 16, a panel mount assembly 22 configured to couple to the display 12 (FIG. 1), and a link arm assembly 24 coupled between the wall mounting assembly 20 and the panel mount assembly 22. Movement of the panel mount assembly 22 relative to the wall mounting assembly 20 is facilitated by at least one of the shafts 28, 42 being subjected to a differential braking torque.
In one embodiment, the wall mounting assembly 20 includes a wall bracket 30 and an add-on bracket 32 that is coupleable to the wall bracket 30. In one embodiment, the wall bracket 30 and the add-on bracket 32 are generally planar members coupled together and attached to a wall that thus defines an X-Y plane. As described herein, the X-axis is oriented horizontally and the Y-axis is oriented vertically, with a Z-axis extending out of the X-Y plane away from the wall.
The wall bracket 30 is configured to be attached to a predetermined (measured) location on wall or other surface by the connector 16, and the add-on bracket 32 is attachable to the wall bracket 30 by any suitable fastening mechanism. In one embodiment, the wall bracket 30 is attached to a wall by connector 16, and a consumer or technician connects the add-on bracket 32 to the wall bracket 30 in a desired location along the X-Y plane.
In one embodiment, the panel mount assembly 22 includes a tilting bracket 40 coupled to the link arm assembly 24, a tilting shaft 42 coupled to the tilting bracket 40 by a hinge 54 a, and panel brackets 44, 46 coupled to the tilting shaft 42. It is to be understood that although two panel brackets 44, 46 are illustrated, the display mounting device 14 can include a single panel bracket 44 or multiple panel brackets.
In one embodiment, at least the tilting shaft 42 is selectively dampened by an appropriate strap/bracket assembly described below that imparts a differential braking torque to the tilting shaft 42. In one embodiment, the differential braking torque necessitates more force when turning the tilting shaft 42 in the counter-clockwise direction (e.g., when tilting the display 12 of FIG. 1 downward for viewing), and a proportionally lower force when turning the tilting shaft 42 in the clockwise direction (e.g., when tilting the display 12 of FIG. 1 upward against the wall W). For example, the weight of the display 12 is countered or offset by the increased torque imparted to the tilting shaft 42 when rotating the shaft 42 in the counter-clockwise direction to tilt the display downward from the wall W toward a seated observer; and when the display is returned to its stowed position against the wall W by tilting the display upward, less force is needed to turn the tilting shaft 42 back in the clockwise direction. The differential braking torque applied to the tilting shaft 42 accounts for the weight of the display 12 as the display 12 is tilted down, and thus has the effect providing equally balanced downward/upward movement of the display 12. In this manner, the differential braking torque applied to the tilting shaft 42 provides the user with a pleasant user-interface.
In one embodiment, the panel mount assembly 22 is movable relative to the wall mount assembly 30 through at least four degrees of freedom including tilt, swing, pan, and telescope degrees of freedom. At least the tilt degree of freedom is dampened by a differential braking torque applied to tilting shaft 42. In one embodiment, all of the degrees of freedom are dampened by a differential braking torque applied to shafts 28 and to tilting shaft 42.
In one embodiment, the link arm assembly 24 includes a first link arm panel 50 pivotably coupled to a second link arm panel 52 by hinge 54 b secured to shaft 28 b, a second hinge 54 c coupled between first link arm panel 50 and add-on bracket 32 and secured to shaft 28 c, and a third hinge 54 d coupled between the second link arm panel 52 and the tilting bracket 40 and secured to shaft 28 d.
The hinges 54 a, 54 b, 54 c, 54 d enable display mounting device 14 to move through multiple degrees of freedom. For example, display mounting device 14 moves relative to the X-Y plane such that the link arm assembly 24 telescopes away from the wall mount assembly 30, brackets 44, 46 sway along the X-axis, brackets 44, 46 tilt around the X-axis, and brackets 44, 46 yaw in an arc around the Y-axis.
The link arm assembly 24 telescopes away from the wall mounting assembly 20 along the Z-axis and is configured to collapse or fold in a nested manner such that the panel mount assembly 22 folds flat against the X-Y plane of the wall mounting assembly 20. In this manner, the display mounting device 14 is configured to mount the display 12 to a wall or any other suitable surface where the display mounting device 14 includes pan, tilt, swivel, swing/sway, and telescoping ranges of motions.
In one embodiment, the display mounting device 14 includes a dual-nested panel asymmetrical design that is characterized by the tilting bracket 40 nesting with the second link arm panel 52, which folds flat against the first link arm panel 54 such that the panel mount assembly 22 nests against/into the wall mounting assembly 20. In addition, the display mounting device 14 has a low profile in which the panel brackets 44, 46 retract to a stowed position that extends from the wall W (FIG. 1) by less than 3.4 inches, preferably by less than 2.4 inches away from the wall, and more preferably by about 1 inch away from the wall W.
FIG. 3A and FIG. 3B are cross-sectional views of two embodiments of attachment mechanisms for shaft 28 b. In one embodiment, shaft 28 b is dampened by friction but does not include the differential braking torque provided to tilting shaft 42. The cross-sectional views are taken through the link arm panel 50.
In one embodiment illustrated in FIG. 3A, a U-shaped member 60 frictionally fits around shaft 28 b and is coupled to the link arm panel 50. The U-shaped member 60 includes opposing flanges 62, 64 that are configured to be fastened to the link arm panel 50 in a manner that squeezes U-shaped member 60 against shaft 28 b. In one embodiment, the U-shaped member 60 defines an inside height H and the shaft 28 b defines an outside diameter D, where the height H of U-shaped member 60 is less than the diameter D of the shaft 28 b. In this manner, when the U-shaped member 60 is attached to the shaft 28 b, for example, via a lock screw, the shaft 28 b is tensioned or damped by the U-shaped member 60. The shaft 28 b is tension-adjustable by selectively adjusting the attachment force of connectors attached between flanges 62, 64 and the link arm panel 50. The tension-adjustable link arm assembly 24 (FIG. 2) enables translation and rotation of the panel mount assembly 22 and the display 12 (FIG. 1).
FIG. 3B is a cross-sectional view of another embodiment of the link arm panel 50 including a hook end 66 that frictionally fits around the shaft 28 b. The hook end 66 includes an end portion 68 that is adapted to be selectively tightened against panel 50 to adjust a level of tension for the shaft 28 b.
FIG. 3C is a perspective view and FIG. 3D is a side view of hinge 54 a including tilting shaft 42 selectively tensioned with a differential braking torque. It is to be understood that the hinge 54 a is generally compatible with any of the panels 40, 50, 52, and any of the panels 40, 50, 52 can be formed to provide differential torque to a respective one of the shafts 28 b, 28 c, 28 d, or 42 (FIG. 2).
In one embodiment, the tilting bracket 40 (or panel 40) includes a base 70 that terminates in a curved pad 72, and the hinge 54 a includes a strap 74 that secures tilting shaft 42 to the curved pad 72. In one embodiment, the tilting shaft 42 defines an outside diameter (OD), and curved pad 72 is formed to be substantially semicircular to have a curvature that is complementary to the OD of tilting shaft 42.
Hinge 54 a is configured such that strap 74 and curved pad 72 combine to provide controlled torque that is delivered to tilting shaft 42 as panel 40 is moved. Hinge 54 a has low inertia such that movement of the panel 40 is accomplished with a moderately low force that need not overcome the weight of the conventional massive tilting mechanisms.
Strap 74 is coupled to base 70 by an adjustment mechanism 76. The strap 74 is configured to be tightened or loosened by adjustment mechanism 76 to selectively adjust a level of braking torque delivered between curved pad 72 and strap 74 to the shaft 28. In one embodiment, adjustment mechanism 76 includes a screw 77 and a nut 78 that threads onto the screw 77 to tighten/loosen strap 74 around a portion of shaft 28. Suitable materials for strap 74 include metals in general. In one embodiment, strap 74 is fabricated from 301 stainless steel. It is also acceptable to fabricate strap from 302 stainless steel or from Austenitic non-hardenable chromium nickel steel. In other embodiments, strap 74 is fabricated from heat treated steel or spring steel.
FIG. 3D illustrates an optional liner 80 provided between shaft 42 and curved pad 72. The optional liner 80 provides a sacrificial bearing that offers some lubricity between the two contacting metals of shaft 42 and strap 74 to minimize or eliminate galling between the metal strap 74 and the metal shaft 42. Suitable materials for the liner 80 include polymers such as nylon, Teflon, or polyester or metal bushings such as brass, bronze, or stainless steel.
In one embodiment, the braking torque delivered to the shaft 42 by the curved pad 72 and the strap 74 is a differential braking torque in which the rotational resistance delivered to the shaft 42 is different between the clockwise and the counter-clockwise directions. For example, in one embodiment, shaft 42 is provided with differential braking torque having a clockwise braking torque T1 that is about 30% less than a counter-clockwise braking torque T2 (e.g., T1 is about 0.7T2). In one embodiment, the clockwise braking torque T1 has a value between 0 to 1200 pounds force-inch (lbs_f-in) and the counter-clockwise braking torque T2 has a value between −3900 to 0 lbs_f-in (the negative value by convention represents counter-clockwise movement). Although it is desired that the clockwise braking torque T1 be less than the counter-clockwise braking torque T2, it is to be understood that for other applications the counter-clockwise braking torque T2 can be less than the clockwise braking torque T1.
In one embodiment, strap 74 is configured to be self-tightening in the counter-clockwise direction, such that torsional rotation in the counter-clockwise direction is met with a greater braking force than torsional movements in the clockwise direction.
In one embodiment, the strap 74 applies a brake force to the tilting shaft 42 to hold/maintain the tilting shaft at rest so the display 12 stays where it has been positioned.
In one embodiment, only the tilting shaft 42 and its hinge 54 a is provided with the differential braking torque. In another embodiment, each of the hinges 54 a, 54 b, 54 c, 54 d provides differential braking torque to its respective shaft 42, 28 b, 28 c, 28 d.
In one embodiment, the panels 40, 50, 52 are provided in a “clamshell” construction having two halves that move independently along a shaft. In one embodiment, a multi-piece clamshell panel as illustrated in FIG. 2 is formed that enables friction-damped link arm assembly 24 to extend and sway relative to wall mounting assembly 20 and panel mount assembly 22. In addition, the clamshell structure enables display mounting device 14 to fold flat against a wall (e.g., the stowed position) at a profile distance of less than 2 inches, and preferably at a distance less than about 1 inch.
FIG. 4 is a side view of the display assembly 10. The display mounting device 14 is connected to the wall W by the connector 16. The display 12 is connected to the panel brackets 44, 46 (one shown) and is configured to telescope/extend away from the wall bracket 30, tilt up/down relative to the wall W, swing left/right relative to the wall W, and translate/pan left and right along an arc.
The display 12 has been tilted down relative to the wall W on the axis of the tilting shaft 42 (the tilting shaft 42 has been rotated in the counter-clockwise direction). In one embodiment, the tilting shaft 42 is subject to differential braking torque that is characterized by more force being called for to rotate the shaft 42 in the counter-clockwise direction (compared to the clockwise direction). The greater differential braking torque in the counter-clockwise direction is overcome by the weight of the display 12. Consequently, the user has the sensation that it is equally easy to tilt the display 12 down as it is to tilt the display 12 back up.
FIG. 5 is a side view of the display assembly 10 illustrating the display mounting device 14 in a stowed position folded against the wall W. The display mounting device 14 provides a low-profile mount for the flat panel display 12. In one embodiment, the display mounting device 14 is collapsible against the wall W such that the display 12 projects a small distance L away from the wall W. In one embodiment, the distance L is less than 3.5 inches, preferably the distance L is less than 2.5 inches, more preferably the distance L is less than 1.5 inches. In one embodiment, the distance L between the display 12 and the wall W is between about 0.5-1.5 inches.

FIG. 6 is a front perspective view of the display mounting device 114, FIG. 7 is a front perspective view of the display mounting device 114 shown in an extended state, and FIG. 8 is a side view of the display mounting device 114 shown in a stowed, low-profile state according to various embodiments. The display mounting device 114 includes a wall mounting assembly 120 that is attachable to a wall or other surface by connectors, a panel mount assembly 122 including the tilting shaft 42 and the hinge 54 a (as described above) coupled to panel 140, and a link arm assembly 124 coupled between the wall mounting assembly 120 and the panel mount assembly 122.
In reference to FIG. 7, in one embodiment the link arm assembly 124 includes a first link arm panel 150, a second link arm panel 152 pivotably coupled to the first link arm panel 150 by hinge 154, a second hinge 156 coupled between first link arm panel 150 and the wall mounting assembly 120, and a third hinge 158 coupled between the second link arm panel 152 and the panel 140 of the panel mount assembly 122. The first and second link arm panels 150, 152 are configured to nest together when the display mounting device 114 is folded flat.
In one embodiment, at least the tilting shaft 42 is configured to include a differential braking torque. In general, the link arm panel 152 is movable relative to the wall mounting assembly 120 through at least four degrees of freedom including tilt, swing, pan, and telescope degrees of freedom, and at least the tilt degree of freedom about the tilting shaft 42 is dampened by a differential braking torque.
In one embodiment, the display mounting device 114 includes a single-nested panel asymmetrical design that is characterized by the second link arm panel 152 folding flat against the first link arm panel 150 such that the panel mount assembly 22 nests against the wall mounting assembly 120.
