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 the drawings, like numerals describe substantially similar components throughout the several views. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments may be utilized and structural, logical changes, etc. may be made without departing from the scope of the present invention.
FIG. 1 shows a mounting device 100 and a display screen 102 coupled to the mounting device 100. In one example, the display screen 102 is a flat panel display, for instance, a plasma television, LCD display or the like. In another example, the display screen 102 is a CRT display, LCD projection display or the like.
As shown in FIGS. 1 and 2, the mounting device 100 includes a mounting panel 104 and a device panel 106 rotatably coupled to the mounting panel 104. The display screen 102 (FIG. 1) is coupled to the device panel 106, in one example with bolts or the like extending through the device panel 106 and coupled with the display screen 102. In another example, the display screen 102 is secured to the device panel 106 with bosses extending from the display screen 102 and secured within corresponding recesses in the device panel 106. Optionally, bosses extend from the device panel 106 are secured within recesses in the display screen 102. The device panel 106, in yet another example, includes the display screen 102 so the display screen 102 is rotatably coupled to the mounting panel 104.
In the orientation shown in FIG. 1, the device panel 106 and the display screen 102 are in an extended position. The device panel 106 and display screen 102 are tilted relative to the mounting panel 104. In one example, the mounting panel 104 is secured to a surface 108, such as a wall, ceiling, column or the like. The mounting panel 104, in another example, is positioned on the surface 108 above the eye level of viewers, for instance, adjacent to the ceiling in a room. In the extended position the display screen 102 is tilted and points generally toward the viewer's eye level.
The mounting device 100, including the mounting panel 104 and the device panel 106 are constructed from steel, in one example. In another example, the mounting device 100 includes, but is not limited to, plastic, wood or the like. The material of the mounting device 100 provides sufficient strength to support the display screen 102 upon the surface 108.
FIG. 2 shows one example of the device panel 106 in the extended position relative to the mounting panel 104. The device panel 106, in this example, includes openings 200 sized and shaped to receive pins, such as bolts, screws or the like to secure the display screen 102 (FIG. 1) to the device panel 106. The mounting panel 104 includes, in another example, mounting openings 202 sized and shaped to receive pins, for instance, bolts, screws or the like to secure the mounting device 100 to the surface 108 (FIG. 1). The mounting panel 104 optionally includes at least one hook and a dog (i.e., a projection) to secure the mounting device 100 to the surface 108, described below.
FIG. 3 shows the device panel 106 in a retracted position relative to the mounting panel 104. The device panel 106 is substantially parallel to the mounting panel 104. In another example, the device panel 106 is disposed along the mounting panel 104 in the retracted position. The device panel 106 is positionable in the retracted, extended and intermediate positions therebetween. In one example, the display screen 102 coupled to the device panel 106 (FIG. 1) is tilted with the device panel 106 into the retracted position. The mounting panel 104 is optionally coupled to the surface 108 (FIG. 1) at or adjacent to eye level and the display screen 102 points generally toward the eye level of the viewer. The mounting device 100 is thereby positionable at various locations on the surface 108 and the device panel 106 is adjustable so the display screen 102 points generally toward the eye level of the viewer.
FIG. 4A is a cross-sectional view showing the display panel 106 in the extended position relative to the mounting panel 104. The mounting device 100 includes an attenuating assembly 400 coupled to an elastic member 402. The elastic member 402, in one example, is coupled between the attenuating assembly 400 and the mounting panel 104. A first portion of the elastic member 402 (e.g., a first end) is coupled to the mounting panel 104 optionally with a tie bar and pretensioning member, described below. A second portion of the elastic member 402 (e.g., a second end) is coupled to the attenuating assembly 400. In another example, the elastic member 402 includes a coiled spring. The elastic member 402, in yet another example, is constructed with a pliable elastomeric material (e.g. a rubber member) coupled between the mounting panel 104 and the attenuating assembly 400. The elastic member 402 operates to counterbalance the weight of the display screen 102 (FIG. 1) on the display panel 106 and assists in retaining the display screen 102 and panel 106 in a desired tilted orientation.
In the example shown in FIGS. 4A, the attenuating assembly 400 includes a first pulley 404 rotatably coupled to the elastic member 402. In one example, a bridge bracket 406 is coupled between the elastic member 402 and the first pulley 404. The bridge bracket 406 couples the first pulley 404 to the elastic member 402. In another example, the first pulley 404 is rotatably coupled to the bridge bracket 406 with a pin 408. The pin 408 extends through the first pulley 404 and is secured to the bridge bracket 406. In yet another example, the bridge bracket 406 includes a shaft 410 extending from the bridge bracket 406. The elastic member 402 includes, optionally, a hook 412 sized and shaped to fit over the shaft 410 and couple the elastic member 402 to the bridge bracket 406 and the first pulley 404.
As shown in FIGS. 4A and 4B, the attenuating assembly 400 includes a flexible element 414, such as a cable, strap, belt or the like coupled between a distal end 416 of the display panel 106 and the mounting panel 104. One portion 418 of the flexible element 414, in an example, is coupled to a bracket 420 extending from the mounting panel 104. In one example, the flexible element 414 extends through a portion of the bracket 420 and a bead 422 is formed around the portion 418 of the flexible element 414. The bead 422 enlarges the outer perimeter of the portion 418 of the flexible element 414 and prevents the flexible element 414 from disengaging with the mounting panel 104. Another portion 424 of the flexible element 414 extends through the distal end 416 of the display panel 106. A similar bead 422 is formed on the portion 424 of the flexible element 414 to secure the flexible element 414 to the distal end 416. The beads 422 are formed around the flexible element 414, for instance, by swaging, molding, crimping, adhering or the like.
The flexible element 414 extends from the bracket 420 around the first pulley 404, around the bracket 420, and couples with the display panel 106. In one example, a second pulley 426 is rotatably coupled to the bracket 420. The second pulley 426 facilitates movement of the flexible element 414 between the display panel 104 and the mounting panel 106. The second pulley 426 ensures the elastic member 402 maintains a substantially parallel orientation with respect to the mounting panel 104. Maintaining the elastic member 402 in the parallel orientation allows the elastic member 402 to expand and contract along the mounting panel 104 and not interfere with the tilting movement of the display panel 106 relative to the mounting panel 104. Additionally, the elastic member 402 and attenuating assembly 400 are positioned adjacent to the mounting panel 104 so the mounting device 100 presents a narrow profile. Optionally, the second pulley 426 is omitted and the mounting panel 104, for instance, the bracket 420 is sized and shaped to slidably couple with the flexible element 414. The bracket 420 maintains the elastic member 402 in the parallel orientation in a similar manner to the second pulley 426.
In the example shown in FIGS. 4A and 4B, the flexible element 414 is in rolling communication with the first pulley 404 and the second pulley 426. The flexible element 414 extends around the first pulley 404 and the second pulley and is coupled to the display panel 106. Movement of the display panel 106, for example, during positioning of a display screen 102 (FIG. 1) correspondingly moves the flexible element 414. Where the display panel 106 is moved between the extended position (FIG. 4A) and the retracted position (FIG. 4B) the elastic member 402 contracts and pulls the flexible element 414 over the first pulley 404 substantially parallel to the mounting panel 104. The flexible element 414 and the elastic member 402 thus move along the mounting panel 104 during movement of the display panel 106. The elastic member 402 and the attenuating assembly 400 are thereby compactly positioned adjacent to the mounting panel 104. Movement of the first pulley 404 through tilting of the display panel 106 contracts the elastic member 402 and decreases the tension in the flexible element 414. The tension in the flexible element 414, at least in part, counterbalances the moment of the display screen 102 (FIG. 1) and substantially prevents undesirable movement of the display panel 106 after the display screen 102 is positioned as desired. As the display panel 106 is moved toward the mounting panel 104 the moment arm of the display screen 102 is decreased and the attenuating assembly 400 cooperates with the elastic member 402 to correspondingly decrease the tension in the flexible element 414.
When the display panel 106 is moved from the retracted position (FIG. 4B) to the extended position (FIG. 4A), the flexible element 414 is correspondingly pulled along with the display panel 106. The flexible element 414 is pulled over the first pulley 404 and the first pulley 404 and the portion of the elastic member 402 coupled to the first pulley are moved along the mounting panel 104 toward the second pulley 426. Movement of the first pulley 404 through tilting of the display panel 106 stretches the elastic member 402 and increases the tension in the flexible element 414. The tension in the flexible element 414, at least in part, counterbalances the moment of the display screen 102 (FIG. 1) and substantially prevents undesirable movement of the display panel 106 after the display screen 102 is positioned as desired. As the moment arm of the display screen 102 increases with extension of the display panel 106 the attenuating assembly 400 cooperates with the elastic member 402 to correspondingly increase the tension in the flexible element 114.
The flexible element 414 has a sufficient length to permit motion of the display panel 106 relative to the mounting panel 104 through a desired range of motion, for instance, 0 to 45 degrees measured from the mounting panel 104. In one example, the flexible element 414 of the attenuating assembly 400 is sized and shaped to attenuate the tension in the elastic member 402. In another example, the tension is attenuated by splitting the tension between the portion of the flexible element 414 extending from the first pulley 404 to the bracket 420 and the portion extending from the first pulley 404 to the display panel 106. The elastic member 402 and the flexible element 414 are sized and shaped to moveably position the first pulley 404 along the flexible element 414, in yet another example, to attenuate the tension in the elastic member 402. Attenuation of the tension in the elastic member 402 with the attenuating assembly 400 substantially prevents undesirable moving of the display panel 106 toward the mounting panel 104 from a desired orientation. Additionally, the flexible element 414 has sufficient length and the first pulley 404 is positioned along the flexible element 414 to substantially prevent the display panel 106 and display screen 102 (FIG. 1) from undesirably tilting away from the mounting panel 104 and the desired orientation.
In another example, the attenuating assembly 400 shortens the travel of the elastic member 402 adjacent to the first pulley 404 during rotation of the display panel 106 relative to the mounting panel 104. Rotation of the display panel 106 translates into movement of the flexible element 114. The flexible element moves over the first pulley 404 and the first pulley is translated a fraction of the distance (e.g., one half the distance) translated by the flexible element 114 because of the relationship between the pulley 404 and the element 114. Without the attenuating assembly 400, the length of the display panel 106 travel and the corresponding arc is limited by the identical length of travel for the elastic member 402. As a result of the attenuating assembly 400, the display panel 106 is moveable through a larger arc because the elastic member 402 moves a fraction of the distance of the flexible element 114 moving with rotation of the display panel 106. In one example, the display panel 106 experiences increased displacement relative to the mounting panel 104 for a given extension of the elastic member 402.
FIG. 5 shows the mounting device 100 including a pretensioning member 502 coupled between the mounting panel 104 and at least one elastic member 402. In the example shown, the pretensioning member 502 is coupled between the mounting panel 104 and two elastic members 402. As shown in FIG. 5, first portions (e.g. ends) of the elastic members 402 include hooks 504 sized and shaped to fit over a tie bar 506. The hooks 412, 504 cooperate to couple the elastic member 402 between the shaft 410 and the tie bar 506. The tie bar 506 is sized and shaped to moveably couple with the pretensioning member 502. In one example, the pretensioning member 502 includes threading and the tie bar 506 includes corresponding threading along an inner surface coupled to the pretensioning member 502. The tie bar 506 extends from the pretensioning member 502 and the elastic members 402 are coupled to the tie bar 506 adjacent to the pretensioning member 502. In another example, the pretensioning member 502 includes a skirt 508, such as a nut, weld, flange or the like at one end of the pretensioning member 502. The skirt 508 is sized and shaped to engage against the tie bar 506 and prevent the tie bar 506 from disengaging from the pretensioning member 502.
The pretensioning member 502, in one example, is turned to translate the tie bar 506 along the member 502. The pretensioning member 502 includes, in another example, a grip 507 (e.g. hex head, hand grip, or the like) sized and shaped to facilitate rotation of the member 502. The threading of the tie bar 506 and the pretensioning member 502 cooperate so rotation of the member 502 correspondingly moves the tie bar 506. Translation of the tie bar 506 along the pretensioning member 502 correspondingly expands or contracts the elastic members 402 and thereby pretensions the elastic members 402 as desired for a particular load, for example, the particular weight of a display screen (FIG. 1). Use of both the pretensioning member 502 and the attenuating assembly 400 allows for operation of the mounting device 100 with a variety of display screens having different weights and correspondingly different moments. For heavier display screens 102 (FIG. 1), the tie bar 506 can be translated along the pretensioning member 502 away from the skirt 508 to increase the tension in the elastic members 402. Conversely, for lighter display screens 102 (FIG. 1), the tie bar 506 can be translated toward the skirt 508 to decrease the tension in the elastic members 402. In one example, the mounting panel 104 includes at least one flange 510. As shown in FIG. 5, two flanges 510 extend from the mounting panel 104. The flanges 510 extend from the mounting panel and into the path of travel for the tie bar 506. The flanges 510 operate to limit the translation of the tie bar 506 and ensure the elastic members 402 have a sufficient tension to counterbalance the weight of the display screen 102 (FIG. 1).
FIG. 6A shows the display panel 106 coupled to the mounting panel 104. In the example shown, a pin 600 extends between the display panel 106 and the mounting panel 104. In one example, the pin 600 is a bolt, screw or the like sized and shaped to extend through the mounting panel 104 and the display panel 106. The pin 600, in another example, includes threading to engage with a nut 602 to facilitate a secure coupling between the mounting panel 104 and the display panel 106. The pin 600 optionally extends from the display panel 106. The pin 600, in one example, is welded or integral to the mounting panel 104.
A washer 604 is interposed between the nut 602 and one of the mounting panel 104 and the display panel 106. The washer 604 is engaged against the nut 602 and one of the mounting panel 104 and the display panel 106. In one example, the washer 604, nut 602 and pin 600 cooperate to snugly couple the mounting panel 104 to the device panel 106. The snug coupling therebetween provides a frictional fitting between the mounting panel 104 and the device panel 106 and assists in preventing unwanted movement of the display panel 106 when positioned as desired (e.g., where the display screen 102 (FIG. 1) points toward eye level). The washer 604 is provided, in another example, to prevent tilting of the display panel 106 from turning the nut 602 and loosening and/or removing the nut 602 from the pin 600. The washer, optionally, is constructed with, but not limited to, a material with a low coefficient of friction, for instance polytetrafluoroethylene. In another option, a lubricious coating 606 is between the washer 604 and one of the mounting panel 104 and the display panel 106. Optionally, the lubricious coating 606 is between the washer 604 and the nut 602. The lubricious coating 606 facilitates sliding movement between the washer 604 and the surfaces against which the washer 604 is engaged (i.e. the nut 602, mounting panel 104, display panel 106). The lubricious coating includes liquid and/or solid lubricants, for instance, molybdenum disulphide, graphite, polytetrafluoroethylene or the like. In one example, the washer 604 includes a material having pores formed therein such as bronze and the lubricious coating is retained within the pores.
FIG. 6B shows another example of a display panel 608 coupled to the mounting panel 104. In the example shown, the display panel 608 includes a first piece 610A extending across the mounting panel 104 and a second piece 610B coupled between one side of the mounting panel 104 and the first piece 610A. A bracket 612, in one example is coupled between the first and second pieces 610A, 610B. The bracket 612 is integral to the second piece 610B, optionally. Pins 614, screws, bolts, rivots, studs or the like extend through the bracket 612 and engage against the first piece 610A to couple the first piece 610A to the second piece 610B. The second piece 610B is moveably coupled to the first piece 610A with the bracket 614 to ensure proper clearance for rotation between the display panel 608 and the mounting panel 104. The first and second pieces 610A, 610B are separately coupled to the mounting panel 104 and the bracket 612 is then coupled between the pieces 610A, 610B. Assembling the first and second pieces 610A, 610B in this manner provides sufficient clearance between the display panel 608 and the mounting panel 104 to permit rotation therebetween. Additionally, providing the second piece 610B separately from the first piece 610A facilitates assembly of the mounting device 100 by allowing alignment of the pin holes between the mounting panel 104 and the first and second pieces 610A, 610B separately. The second piece 610B, optionally, is then easily coupled to the first piece 610A with the bracket 612 afterwards. With the single piece construction for the display panel 106 both pin holes are aligned with the corresponding holes in the mounting panel 104 in a single step to assemble the mounting device 100.
Referring again to FIG. 6B, the pin 600 extends between the display panel 608 and the mounting panel 104. In one example, the pin 600 is a bolt, screw or the like sized and shaped to extend through the mounting panel 104 and the display panel 608. The pin 600, in another example, includes threading to engage with the nut 602 to facilitate a secure coupling between the mounting panel 104 and the display panel 608. A washer 604, such as a spring washer, is interposed between the nut 602 and one of the mounting panel 104 and the display panel 608. In one example, the washer 604 is interposed between the nut 602 and the display panel 608. The washer 604 provides a biasing force that pulls the pin 600, including the head of the pin into engagement with the mounting panel 104 and presses the mounting panel 104 toward the display panel 608. In another example, a lubricious washer 616 is interposed between the washer 604 and the nut 602. The lubricious washer 616 is constructed with, but not limited to, a porous bronze in example. The pores of the washer 616 are filled with liquid and/or solid lubricants, for instance, molybdenum disulphide, graphite, polytetrafluoroethylene or the like. The lubricants facilitate sliding movement between the lubricious washer 616 and the surfaces against which the washer 616 is engaged (i.e. the nut 602 and the washer 604). The lubricious washer 616 is provided to prevent tilting of the display panel 608 from turning the nut 602 and loosening and/or removing the nut 602 from the pin 600.
A second washer 618 is provided, in one example, between the mounting panel 104 and the display panel 608. The second washer 618 is sized and shaped to span a gap between the mounting panel 104 and the display panel 608 to ensure a snug coupling therebetween. The snug coupling provides friction between the mounting panel 104 and the display panel 608 and assists in preventing unwanted movement of the display panel 608 when positioned as desired (e.g., where the display screen 102 (FIG. 1) points toward eye level). In another example, the washer 604 is a spring washer and provides tension to the pin 600 snugly couple second washer 618 between the mounting panel 104 and the display panel 608 to provide friction therebetween.
FIG. 7 is a rear perspective view of the mounting device 100. The mounting panel 104 includes, in one example, at least one fastener 700, such as a hook or the like. As shown in FIG. 7, two fasteners 700 extend from the mounting panel 104. The fastener 700 is sized and shaped to engage against, for instance, the surface 108 (FIG. 1) and secure the mounting device 100 to the surface 108. In another example, the fastener 700 is sized and shaped to engage against a surface bracket (described below). The fastener 700 is optionally disposed within an opening in the surface (e.g., a hole in a wall) to hang the mounting device 100 on the surface 108. The fastener 700 is integral to the mounting panel 104, in another example. In yet another example, the fastener is coupled to the mounting panel 104, such as by welding, bolting or the like.
At least one dog 702, for instance a projection, flange or the like, extends from the mounting panel 104 in another example. In the example shown in FIG. 7, two dogs 702 extend from the mounting panel 104. The dog 702 is sized and shaped to fit within an opening in the surface 108 (FIG. 1), in one example. In another example, the dog 702 is sized and shaped to couple with a surface bracket (described below) to retain the mounting device 100 against the surface 108. The dog 702 includes a lip 704 optionally for engagement with a detent surface (described below). The dog 702 assists in distributing the weight of the mounting device 100 otherwise carried by the fastener 700. The dog 702 cooperates with the fastener 700 to substantially prevent accidental disengagement of the mounting device 100 from the surface 108. For example, force applied to the device panel 106 to rotate the panel 106 toward the mounting panel 104 is transmitted to the mounting panel 104 and moves the mounting panel 104 up along the surface 108 (FIG. 1). Sufficient force will move the fastener 700 out of engagement with the surface 108 and undesirably uncouple the mounting device 100 from the surface 108. Disengagement of the mounting device 100 in this manner is a concern as the mounting device 100 can unintentionally fall from the surface 108. Additionally, the display screen 102 (FIG. 1) could be damaged with an unintended disengagement and fall with the mounting device 100.
The dog 702 remains engaged against the surface 108 with movement of the device panel 106. The dog 702, in one example, extends substantially orthogonal to the mounting panel 104 and thereby remains engaged against the perimeter defining the opening in the surface 108 despite movement of the display panel 106. In another example, the cooperative engagement of the fastener 700 and dog 702 to the surface 108 allows for safe disengagement of the mounting device 100 from the surface 108. The mounting panel 104 is pulled near a lower edge to rotate the panel 104 around the fastener 700. The dog 702 disengages from the surface 108 and the fastener 700 is disengaged from the surface 108 by pulling the mounting panel 104 away from the surface 108.
FIG. 8 is a rear perspective view of a surface bracket 800 for coupling the mounting panel 104 to the surface 108 (FIG. 1), in one example. The surface bracket 800, includes corrugations 802A, 802B. Openings 804, in another example, are disposed around the surface bracket 800 and on either side of the corrugations 802A, 802B. The openings 804 are sized and shaped to receive pins, screws, bolts or the like to couple the surface bracket 800 to surface 108 (FIG. 1). The fasteners 700 (FIG. 7) are received within cavities 806 in the corrugation 802A so the mounting panel 104 is hung from the surface bracket 800. Corrugation 802B includes apertures 808 sized and shaped to receive the dogs 702 extending from the mounting panel 104 (FIG. 7). A moveable member 810 with detent surfaces 812 is slidably coupled to the surface bracket 800 and disposed within the corrugation 802B. Pins 814 extend from the corrugation and through slots 816 of the moveable member 810 so the member 810 moves around the pins 814. The pins 814 include flanges for securing the moveable member 810 around the pins and thereby slidably coupled to the corrugation 802B.
An actuator lever 816 is moveably coupled to the surface bracket 800 and rotatably coupled substantially adjacent to one end of the lever 816 to the moveable member 810, in one option. A pin 818, for example, extends from the moveable member 810 and is received within a channel 820 in the actuator lever 816. Movement of the actuator lever 816 is transmitted to the moveable member 810 and correspondingly moves the detent surfaces 812. In one example, the actuator lever 816 moves the detent surface 812 into and/or out of engagement with the dog 702 (FIG. 7). Optionally, a biasing member 822, such as a spring or the like, is coupled between the pin 818 and the pin 814. The biasing member 822 is pretensioned and acts to pull the moveable member 810 and detent surface 812 into engagement with the dogs 702.
FIG. 9 is a front perspective view of the surface bracket 800. The actuator lever 816, in one example, is shown rotatably coupled to the surface bracket 800 by a fastener 823, such as a pin, screw or the like. The detent surfaces 812 are shown extending over a portion of the apertures 808. In this position, a first flange 824 of the actuator lever 816 is substantially adjacent to a second flange 826 extending from the surface bracket 800. The first flange 824 and the second flange 826 optionally include an opening 828 extending therethrough. A bolt, screw, pin or the like is placed within the opening 828 to couple the first flange 824 with the second flange 826. In one example, a bolt is tightened around the first and second flanges 824, 826 to secure the actuator lever 816 and prevent unwanted movement of the lever 816 that may cause, for instance, disengagement of the detent surfaces 812 from the dogs 702.
FIG. 10 is an exploded view of the surface bracket 800 and the mounting device 100. In one example, the surface bracket 800 is coupled to the surface 108 (FIG. 1). To couple the mounting panel 104 to the surface bracket 800 the fasteners 700 are seated within the cavities 806. The mounting panel 104 is engaged against the surface bracket 800 so the dogs 702 are at least partially disposed within the apertures 808. As shown in FIG. 10, the biasing member 822 operates to pull the moveable member 810 so the detent surfaces 812 overlay at least a portion of the apertures 808. The lips 704 of the dogs 702 engage against the detent surfaces 812 and the surfaces defining the apertures 808. In one example, pressure applied to the mounting device 100 toward the surface bracket 800 pushes the dogs 702 further into the apertures 808 and correspondingly moves the detent surfaces 812 aside to allow entry of the dogs 702. Once the lips 704 move beyond the detent surfaces 812, the detent surfaces 812 move back through force applied by the biasing member 822. The detent surfaces 812 partially overlay the apertures 808 to prevent the dogs 702, that have larger profiles than the partially occluded apertures 808, from moving out of the apertures 808. The lips 704 are engaged against the moveable member 810 and the mounting panel 104 is securely coupled to the surface bracket 800. In another example, the actuator lever 816 is moved to correspondingly move the detent surfaces 812 to allow the dogs 702 and lips 704 to move through the apertures 808. The actuator lever 816 is released so the detent surfaces 812 overlay the apertures 808 and prevent the dogs 702 from moving out of the apertures 808. As a result, the mounting panel 104 is securely coupled to the surface bracket 800. To uncouple the mounting device 100 from the surface bracket 800 the operation described above is substantially repeated in reverse order.
FIG. 11 is a block diagram illustrating a method 1100 for making a mounting device. One example of a mounting device (i.e. mounting device 100) is shown in FIGS. 4A and 4B, and is referred to below. At 1102, a device panel 106 is rotatably coupled to a mounting panel 104. In one example, the device panel 106 is coupled to the mounting panel with a pin 600 (FIG. 6) extending therebetween. At 1104, a first portion of at least one elastic member 402 is coupled to the mounting panel 104. The elastic member 402, in one example, includes at least one coiled spring. At 1106, a first pulley 404 is rotatably coupled substantially adjacent to a second portion of the at least one elastic member 402. In one example, a bridge bracket 406 is coupled between the first pulley 404 and the second portion of the at least one elastic member 402. At 1108, a flexible element 414 is coupled between the mounting panel 104 and the device panel 106. The flexible element 414 is in rolling communication with the first pulley 404. In one example a second pulley 426 is rotatably coupled to the mounting panel 104, and the second pulley 426 is in rolling communication with the flexible element 414. In another example, a plasma display (e.g. a display screen 102 shown in FIG. 1) is coupled to the device panel 106.
Optionally, a fastener 700 (FIG. 7) is provided that extends from a face of the mounting panel 104. In another example, a dog 702 is provided that extends from a face of the mounting panel 104. The method 1100 includes, for example, coupling the dog 702 with a surface bracket 800 (FIG. 10). A detent (e.g. detent surface 812) is engaged against the dog 702 to secure the mounting panel 104 to the surface bracket 800.
In one example, a washer (e.g. washer 604 shown in FIG. 6) is engaged to at least one of the device panel 106 and the mounting panel 104. The pin 600 extends through the washer 604, and a nut 602 coupled around the pin 600 engages against the washer 600. In another example, a lubricious coating is applied between the washer 604 and at least one of the device panel 106 and the mounting panel 104.
In another example, a first portion of a second elastic member 402 is coupled to the mounting panel 104 and a second portion of the second elastic member 402 is coupled to the bridge bracket 406. In yet another example, a pretensioning member 502 (FIG. 5) is coupled to the mounting panel 104. Optionally, the at least one elastic member 402 is coupled to a tie bar 506 and the tie bar is moveably secured to the pretensioning member 502.
CONCLUSION
Using examples described above, a number of advantages are realized. One advantage includes a mounting device having an attenuating assembly to retain a display panel in a desired orientation. The attenuating assembly, assists in preventing an elastic member from moving the display panel toward a mounting panel. The attenuating assembly also transmits sufficient moment to the display panel to counterbalance the moment provided by the weight of the display panel and a display screen coupled thereto. Another advantage includes a compact mounting device having the attenuating assembly and the elastic member extending along the mounting panel so the mounting device presents a narrow profile. As a result, the mounting device takes up little space when mounted to a surface, such as a wall or ceiling. Another advantage includes a mounting device with a pretensioning member to ensure sufficient tension is provided by the elastic member to retain the display panel and the display screen in a desired orientation.
