A display stand can be adjustable to allow a user to ergonomically place the display for use. A display may be able to tilt or raise and lower to optimize the placement of the display in an ergonomic position. If a display can tilt forward and backward the display mount may include hinges that attach to the base. The hinges can be attached to both the display and the base with screws to support the weight of the display or the hinge may not be removable from the display or the base. A display may include openings on the back used to attach the display to mounting brackets. The mounting brackets that can be attached to the opening on the back of the display may be 100 millimeters apart in a square pattern known as the Video Electronics Standards Association (VESA) standard. The mounting brackets may be a swing arm or a wall bracket.
Some embodiments of the invention are described with respect to the following figures:
a is a mounting bracket according to an example embodiment of the invention;
b is a mounting bracket according to an example embodiment of the invention;
A panel used in a display to display images can be made in different thicknesses and weights depending on the technology of the panel. For example a Liquid Crystal Diode LCD panel has at least the LCD layer and a backlight layer and an Organic Light Emitting Diode Panel has just the diode layer. As the panel technology becomes thinner the display enclosures supporting the panels cannot be reduced because of inclusion of standards such as VESA mounting.
The VESA standard increases the thickness of the display enclosure by having openings to screw fasteners on the back of the display enclosure. The opening may have a depth of about 1 cm to allow the mounting bracket to securely attach to the display enclosure adding an additional 2.5 cm to the thickness of the display enclosure. The additional 2.5 cm of thickness on the display enclosure can add additional costs to the display enclosure in additional materials and weight to the display and the packaging of the display.
The base and column for a VESA standard display has to be at least the distance between the openings on the back of the display and the bottom of the display. For example if the VESA opening on the display are in the midpoint of the back of the display, a stand may be at least one half as tall as the display. If the stand mounted lower on the back of the display the material for the stand may be reduced.
A display that attaches to a VESA base has an opening to attach the base. The base can include parts that allow the display to be adjusted: For example the base may include a hinge to allow the display to tilt if it is attached to the base. To replace the base with another type of support for the display, such as a wall mount, the wall mount bracket may use a hinge to allow the display to tilt relative to the wall mount bracket and the hinge would have to be on the wall mount bracket. Having a hinge on all the different mounts that the display can attach to can add to the cost of the display because a hinge is used on each stand or mounting bracket. Attaching a hinge to the display can allow the display to be adjusted irrespective of the base or mounting bracket the display is attached and can reduce the number of hinges because each mounting base or mounting bracket does not have to include a hinge for the display to be adjustable.
With reference to the figures,
A leaf knuckle 111 can be connected to the knuckle 121 by a pin 115. In one embodiment there can be a leaf knuckle 111 for each knuckle 121 on the base 120. If there is a leaf knuckle 111 for each knuckle 121 on the base then there may be a pin 115 for each connection between the knuckle 121 and the leaf knuckle 111. In an alternative embodiment the leaf knuckle 111 may extend between the knuckles 121 and the pin 115 may extend from the one knuckle 120 to another knuckle 120.
The leaf 110 can be one piece extending from the leaf knuckles 111 connected to the pin 115. The leaf 110 can extend from leaf knuckles 111 to the bottom 106 of the display 100. If the leaf 110 does not extend past the bottom 106 of the display 100, the display 100 may take up less space when packed for shipping. The leaf 110 can be flat so that the leaf 110 does not add additional thickness to the display 100. In one embodiment, flat means that the length and the width of the leaf are multiple times greater than the thickness of the leaf. For example if the leaf is 5 centimeters long and 5 centimeters wide the thickness may be 0.5 centimeters.
If the leaf 110 is supported by a base the weight of the display may cause the display to lean forward or backward until the display reached the end of the travel allowed by the hinge. Force may be applied to the hinge to counter the weight of the display. For example friction may provide a force that is capable of countering the force exerted by gravity on the display. The friction may be provided by a clutch between the knuckle 121 and the leaf knuckle 111. The clutch can have a spring to apply a force to a clutch plate causing friction between the clutch plate and the knuckle 121 or the leaf knuckle 111 to counter gravity on the display 100. In another embodiment a torsion spring can be used to counter gravity on the display 100. The torsion spring can surround the pin 115 and apply a force between the leaf 110 and the hinge base 120.
The leaf 110 can include a fastener 125 to lock the leaf 110 to a receiver. The fastener 125 may be an aperture in the leaf. In one embodiment the aperture is a cavity in the surface of the leaf 110 and in another embodiment the aperture is an opening extending through the leaf 110. The leaf 110 may include other types of fasteners for example a locking wedge or a threaded opening. In one embodiment, the leaf 110 may include multiple fasteners 125 on the leaf 110. In one embodiment, the leaf 110 may have a notch 126 in one edge of the leaf 110. For example the leaf 110 may have a notch 126 in the bottom edge of the leaf 110 to stabilize the leaf in a receiver.
In one embodiment the leaf 110 can have a rectangular shape or portion or alternatively a keystone, trapezoidal, or triangular shape or portion. For example the portion of the leaf 110 that is received by the receiver may have a keystone, trapezoidal, or triangular shape while the remaining portion of the leaf 110 has another shape. The keystone or trapezoidal leaf 110 can include the top and bottom of the leaf 110 being parallel to each other and at least a portion of the sides of the leaf 110 are not parallel. A leaf 110 with a triangular shape can have at least a portion of the sides of the leaf 110 that are not parallel to each other. A leaf 110 with a keystone, trapezoidal, or triangular shape can provide a stable connection to a receiver by exerting force on the receiver by the two sides of the leaf instead of the bottom of the leaf 110.
The display 100 may have a port 103 on the back 105 of the display 100. The port 103 may be used to connect the display to a power source for example an alternating current power receptacle or a data source such as a computing device. A computing device may be a portable computer, desktop computer, server computer, personal digital assistant, phone or another computing device. The port 103 be can configured so that a cable connected to the port 103 is perpendicular to the back 105 of the display 100. If the cable connected to the port 103 is perpendicular to the back 105 of the display 100, it is less likely that the cable may prevent adjustments made to the hinge leaf 110.
The column 245 can include an aperture 250 in the top 246 of the column 245. The aperture 250 can receive the leaf of the display. In one embodiment a column 245 includes the fastener and couples to the leaf fastener on the leaf of the display. If the column includes a fastener to couple to the leaf fastener of the display, the fastener can lock the column to the leaf until a release 248 is activated to unlock the coupling between the fastener in the column 245 and the leaf fastener. The column and the foot can be flat so that the length and the width of the column and the foot are multiple times greater than the thickness of the column and the foot. For example if the foot is 20 centimeters long and 20 centimeters wide the thickness may be 1 centimeter.
a is a mounting bracket according to an example embodiment of the invention. The mounting bracket 300 includes a first mounting plate 355. The mounting plate 355 can include an opening 365 to attach the mounting plate to another object, for example the opening 365 can be used to attach the mounting bracket 300 to a wall or to a display arm. In one embodiment there may be multiple openings 365 in the mounting plate 355 to attach the mounting plate 355 to a VESA compliant arm, base or another display support device. In one embodiment the openings 365 may be threaded to receive screws from a VESA compliant arm.
The mounting bracket 300 can include a support 360 that is connected to the mounting plate 355. The support 360 may be for example perpendicular to the mounting plate 355. The receiver 370 can be connected to the edge of the mounting plate 355. The receiver 370 can be for example at an obtuse angle to the surface 361 of the support 360. The receiver 370 can accept the leaf of the display. In one embodiment gravity and the weight of the display holds the leaf in the receiver 370. In one embodiment friction can hold the leaf in the receiver. In another embodiment the receiver 370 may include a fastener to lock the leaf in the receiver 370 and the fastener may have a release for the lock.
b is a mounting bracket according to an example embodiment of the invention. The mounting bracket can receive a leaf from a display. If the leaf on the display is connected to a hinge, the receiver 370 on the mounting bracket can be oriented at different angles relative to the support 360, for example the receiver 370 may include brackets attached to the support 360. In one embodiment the receiver can include a fastener to lock the leaf in the receiver if the force of gravity may not hold the leaf in the receiver. In one embodiment the support 360 is part of the receiver 370 and the leaf may be inserted between the receiver 370 and the support 360.
In one embodiment the support 460 of the mounting bracket 400 can include a cable opening 470 in the support 460 to allow the cables that can connect to the display to pass through the bottom of the mounting bracket 400. In one embodiment the support 460 and the mounting plate 455 are connected by a hinge. The hinge can allow the mounting bracket to fold to reduce the volume of the packaging used for the mounting bracket 400. The support 460 can also be used to place devices such as a docking station, KVM (keyboard video mouse) switch, a computing system or another device. The support 460 may have a tab at the end of the support 460 to prevent a device from being moved off of the support 460 without lifting the device.
The mounting bracket 400 can include a receiving plate 495. The receiving plate can include leaf brackets 490 to insert the leaf of a display between. The leaf brackets 490 may be part of the receiving plate or may be removable to allow the mounting bracket to be adapted to different leafs.
The mounting bracket 400 may also include a fastener 485. The fastener 485 may be for example wedge shaped and may connect to a fastener in a leaf of a display if the leaf is inserted in the leaf brackets 490. In one embodiment the fastener 485 is supported by a flexible member 480. The flexible member can allow the fastener 485 to deflect if a leaf is inserted in the leaf brackets 490 and return to its undeflected position when the fastener 490 is aligned with the aperture in the leaf. In one embodiment the flexible member may also include a release 475 to deflect the fastener 485 to unlock the leaf from the leaf brackets 490. The release 475 may also stop the leaf from being inserted too far into the leaf brackets 490, in one embodiment. The release 475 may also stabilize the leaf in the leaf brackets 490 if the leaf is loose in the leaf brackets 490 and a notch may be included on the leaf to lessen the lateral movement of the leaf between the leaf brackets. The fastener 485, flexible member 480 and the release 475 may be removable with the leaf brackets 490 to adapt the mounting bracket to different leafs.
The foot 235 and the column 245 can be separated. In one embodiment the length and width of the foot 235 and the length and width of the column 245 can be less than the length and width of the display 100. For example if the display is 35 centimeters wide and 40 centimeters long the width of the foot and the column can be less than the 35 centimeters and the sum of the length of the foot and the length of the column can be less than 40 centimeters to allow the column 245 and the foot 235 to be placed on the back 105 of the display 100 to minimize the thickness of the display system and reduce the volume of the packaging and thus reduced the packaging.
If the leaf of the display is not connected to a receiver, the display can be flattened by adjusting the leaf. Flattening the display may include for example adjusting the hinge so that the leaf is parallel to the back of the display to reduce the overall thickness of the display and to reduce the volume of the packaging for the display.
If the leaf on the display is inserted in a receiver the display can be tilted by adjusting the hinge between the display and the leaf. Tilting the display can provide a user an ergonomic position in which to view the display. The display may be tilted relative to a base with a receiver that rests on a surface, for example a desk, or the display may be tilted relative to a mounting bracket with the hinge.
