Abstract
Description
- The present application claims the benefit of U.S.
Provisional Application 60/755811, filed Jan. 3, 2006, and incorporated herein in its entirety by reference. - The present invention relates to mounting devices for electronic displays, and in particular, remotely selectively positionable mounting devices for flat panel electronic display devices.
- Flat panel electronic display devices such as flat panel televisions and display monitors are becoming increasingly popular due to superior image quality, space utilization, and increasing affordability as compared with conventional CRT displays. These flat panel display technologies have proven especially well suited to screen sizes over 36 inches, above which the size and weight of a CRT device become prohibitive.
- In very large screen sizes, however, even flat panel electronic displays are heavy and difficult for an individual to manage. Further, it is often desirable to position a display to be in a better position for viewing. This typically involves moving the display away from a wall so the screen may be tilted from side-to-side over a wider range of motion. While this may be accomplished in some instances by mounting the display on a wheeled cart, this approach has drawbacks. One problem with such an approach is that the large mass of the flat panel display may make the combination top-heavy and prone to tipping. Another drawback is that the cart takes up floor space, thereby negating part of the space advantage of a flat panel display. Moreover, for full positioning capability, the cart must be remotely positionable as well as the display itself, making for a relatively complex position control system.
- Another approach is to mount the flat panel display from a wall or other structural element. Prior wall mounting devices have been developed that enable wall mounting of a flat panel display with remote positioning capability. These prior devices, however, have certain drawbacks. One such device is disclosed in published PCT application WO 2005/052435 A1. In this device, threaded rods are joined together in a rectangular configuration whereby each threaded rod supports a movable carriage including a linear actuator thereon. The flat panel display device is coupled with each carriage through a rigid tube. As the linear actuators are moved along the threaded rods as directed with the remote control, the screen of the flat panel display is moved outwardly from the wall and tilted from side-to-side and up-and-down. A drawback of this device, however, is the display device causes relatively large structural loads to be placed on the threaded rods, tubes and linear actuators when the display is cantilevered a significant distance from the wall. The size of these elements must be made correspondingly large to accommodate this loading, adding to the space demands, weight, and cost of the mounting device. Further, the device requires a relatively large number of actuators or motors, adding to the cost of the device and complexity of the control systems.
- Another prior remotely positionable mount is disclosed in US published patent application U.S. 2005/0179618 A1 entitled “VIEWING ANGLE ADJUSTMENT FOR A MONITOR.” In this device, a known swing arm type cantilever mount is modified with a rotary positioning motor at each arm connection. A drawback of this device, however, is that a relatively complex control system is needed to monitor and control the multiple positioning motors. Further, even with such a complex control system, the resulting positioning movement of the display is likely to be somewhat non-uniform and halting due to the need to assimilate position feedback signals in the control system.
- What is still needed in the industry is a wall mount for an electronic flat panel display device that exhibits good structural strength characteristics in a relatively simple design that is as well relatively lightweight and compact and that enables remotely controlled positioning of the display with a smooth motion.
- The present invention addresses the need of the industry for a flat panel display mount that exhibits good structural strength characteristics in a relatively lightweight and compact form, and that enables remotely controlled positioning of the display with a smooth motion. In embodiments of the invention, a motorized mount includes a wall interface assembly and a display device interface operably coupled by a scissor arm assembly. The scissor arm assembly is compounded for strength, each arm comprising two parallel arms. One end of one compounding arm of the scissor arm assembly is coupled to a positioning member threadedly engaged with a vertical screw in the wall interface driven by a motor, which the other end is pivoted to the display interface. One end of the other compounding arm is slidably received on a vertical shaft on the display interface, while the other end of the same arm is pivoted to the wall interface. When the motor is actuated, the positioning block is moved up or down on the screw, thereby causing the display interface to be moved closer to or away from the wall by the scissor arm assembly in a generally horizontal plane. A second positioning motor may be attached to the scissor arm assembly and coupled to the display interface through a geared arrangement to enable side-to-side rotation of the display interface about the shaft axis. Each motor may be remotely controlled using known remote control systems, including wired and wireless control systems.
- In an embodiment, the present invention includes a motorized mount for an electronic display, and includes a biaxially shiftable mount assembly including a positioning assembly being translatably shiftable in a plane and a rotator assembly operably coupled to the positioning assembly, the rotator assembly being roatably shiftable about an axis, the axis being orthogonally disposed relative to the plane. An embodiment of the present invention may further include a method of selectively positioning an electronic display.

FIG. 12 is a fragmentary view of a portion of the mount ofFIG. 11 . - A motorized mount according to an embodiment of the present invention is depicted generally at 20 in the figures. Motorized
mount 20 generally has three major components:wall interface assembly 22,display device interface 24 andpositioning assembly 26, as depicted inFIGS. 1 and 6 . - The first component of motorized
mount 20 iswall interface assembly 22, shown particularly inFIGS. 2, 3 , 7, 11 and 12.Wall interface assembly 22 generally includeshousing 28 having a pair of laterally projectingflanges 30.Housing 28 may have a width dimension W (seeFIG. 2 ) defined between theflanges 30 and selected so as to correspond with the spacing between adjacent studs of standard stud spacing in frame wall construction such stud spacing is, for example, 16 inches or 24 inches on center. Eachflange 30 may have one ormore apertures 32 for receiving fasteners 34 (seeFIG. 11 ) to attachwall interface assembly 22 to studs 36 in a wall 38. Mechanism cover 40 (seeFIG. 12 ) may be provided to cover all or a portion of the interior ofhousing 28 when installed in the wall 38. - The second component of motorized
mount 20 isdisplay device interface 24, shown particularly inFIGS. 4, 5 , and 9.Display device interface 24 generally includesinterface plate 42 and fastening buttons 44.Interface plate 42 has a plurality ofapertures 46 defined therein for receiving fastening buttons 44, which are attached to flatpanel display device 48. Various arrangements of apertures and fastening buttons that may be used to attach flatpanel display device 48 tointerface plate 42 are described in U.S. patent application Ser. No. 10/821,395 entitled FLAT PANEL DISPLAY MOUNTING SYSTEM, commonly owned by the owners of the present invention and hereby incorporated herein in its entirety by reference. In other embodiments of the invention,display device interface 24 may include a perimeter frame structure 50 (seeFIG. 11 ) having inside dimensions slightly greater than the outside dimensions of a certain flatpanel display device 48 and into which the flatpanel display device 48 may be received. In these embodiments, flatpanel display device 48 may be attached to frame 50 using any attaching means known in the art. - The third component of
motorized mount 20 is positioningassembly 26, shown particularly inFIGS. 2-5 , 11 and 12. Positioningassembly 26 generally includes means for shiftably translating thedisplay device interface 24 in a plane that is substantially horizontal or parallel with a floor of a room in which themotorized mount 20 is mounted. Positioningassembly 26 generally includes screw drive assembly 52,scissor arm assembly 54,slide assembly 56 androtator assembly 58. Screw drive assembly 52 generally includesscrew 60, positioning block 62, motor 64, and thrust bearing assembly 66.Screw 60 has a spiral thread 68 formed thereon and extending over its full length. Motor 64 is attached to inside surface 70 ofhousing 28 and has an output shaft 72 attached to one end 74 ofscrew 60. Opposite end 76 ofscrew 60 is coupled to thrust bearing assembly 66 at thrust bearing 78. Thrust bearing 78 is rotatably received in thrust bearing housing 80, fixed to bottom wall 82 ofhousing 28. Positioning block 62 hasbody portion 84 with a pair of cylindrical stub shafts 86 extending laterally, coaxially from each opposed side 87 of thebody portion 84. Bore 88 is transversely defined from top to bottom through positioning block 62. Bore 88 has an internal thread (not depicted) formed therein corresponding with thread 68 ofscrew 60, so that positioning block 62 is shiftably threaded ontoscrew 60. -
Scissor arm assembly 54 ofpositioning assembly 26 is depicted inFIG. 11 and generally includes first arm pair 90 andsecond arm pair 92. As such,scissor arm assembly 54 is compounded with eacharm pair 90, 92 comprising an arm ofscissor arm assembly 54. This is in distinction to the conventional construction of a scissor arm that has single bars pivotally coupled to each other. First arm pair 90 generally includes parallelly disposedarms scissor arm assembly 54. Each ofarms portion angled portion bore 105 formed therethrough. The respective bores 105 are in registry for receivingpivot axle 106 on respective opposed ends ofpivot axle 106. Opposite ends 108, 110, ofarms -
Second arm pair 92 generally includesarms scissor arm assembly 54.Arms arms housing 28. Pivot axles 136, 138, extend througharms bracket pair arms housing 28. Each pivot axle 136, 138 has a respective head portion 146 and a respective opposing end 148. Each respective opposing end 148 has an aperture for receiving a cotter pin 150 to secure pivot axles 136, 138 in place. - Each
arm pair 90, 92, has an aperture (not depicted) intermediate the head portion 146 and the opposed end 148 for receiving central pivot axle 152. Central pivot axle 152 extends through both arm pairs 90, 92, and enablesarms 90, 92, to angularly pivot together in a compound scissors configuration, such pivoting acting to extend or retract the head portion 146 and the opposed end 148 relative to each other along an axis transverse to wall 38 and lying in a generally horizontal plane. Such extension and retraction acts to effectively lengthen and shorten the overall length of thescissor arm assembly 54, thereby positioning thedisplay device interface 24 transversely relative to the wall 38 in the plane noted above. -
Slide assembly 56 ofpositioning assembly 26 generally includesshaft 154 and slide 160.Shaft 154 is fixed to interfaceplate 42 atbosses 156, 158. Slide 160 is slidably received onshaft 154. Pivot axle 130 extends through fastening tabs 126, 128, and slide 160 to pivotally attacharms -
Rotator assembly 58 of positioning assembly 26 (seeFIGS. 8-11 ) generally includes means for shiftably rotating thedisplay device interface 24 about an axis disposed orthogonally to the plane of actuation of thepositioning assembly 26, noted above.Rotator assembly 58 generally includes housing portion 162,motor 164,drive gear 166, andpositioning gear 168. Housing portion 162 andpositioning gear 168 are rotatably mounted onshaft 154. Bearing portion 170 ofpositioning gear 168 bears againstinterface plate 42.Pivot axle 106 extends through fastening tabs 102, 104, and housing portion 162, to pivotally attacharms Motor 164 is fixed to housing portion 162 and has its output shaft coupled withdrive gear 166, which is in turn, meshed withpositioning gear 168. - Motor 64 and
motor 164 may be electric motors with output shafts connected through reduction gear assemblies to provide a low speed bi-directional rotary output. Each motor is operable through a separate control so that each motor may be operated independent of the other. - In operation, power is applied to motor 64, causing it to rotate
screw 60 in either a clockwise or counter-clockwise direction. Asscrew 60 rotates, positioning block 62 moves vertically along the length ofscrew 60, the direction of movement depending on the direction of rotation ofscrew 60. The vertical movement of positioning block 62 causes scissorarm assembly 54 to movedisplay device interface 24 either closer to, or further away from,wall interface assembly 22, thereby retracting or extending flatpanel display device 48 from the wall in the plane noted above. - Power may also be separately applied to
motor 164, thereby causing it to rotatepositioning gear 168 throughdrive gear 166 in either a clockwise or counterclockwise direction through a known angle about an axis (the longitudinal axis of shaft 54) that is orthogonally disposed relative the plane of extension/retraction ofscissor arm assembly 54. Such rotation imposes opposing biases on theinterface plate 42. Bearing portion 170 selectively bears againstinterface plate 42 on one side or the other of the axis of rotation in the direction of gear rotation, thereby causinginterface plate 42 to rotate onshaft 154 in a selected direction. Such rotation selectively positions theflat panel display 48 attached to interfaceplate 42 for better viewing as desired. - In an embodiment of the invention,
motor 64 and 164 may be controlled remotely through a receiver associatedmotorized mount 20 and a remote transmitter. The receiver and transmitter may be communicatively connected via hardwire or various wireless modes including modulated infrared signals where line-of-sight control is desired, or through modulated radio-frequency signals for greater range. In embodiments of the invention, remote control ofmount 20 may be incorporated in the same transmitter with remote control of one or more of the flat panel television, satellite receivers, digital media players, sound systems, or other electronic devices associated with the flat panel television as is known in the art. - Although a specific arrangement is disclosed above, it will be evident to those of skill in the art that other embodiments are encompassed within the scope of the invention. For example, in an embodiment, the positioning assembly may be located in the display interface, with the slide assembly located in the wall interface.
