## Title
Foot support assembly for cantilevered touch screen

## Abstract

A computer *display is pivotally connected to at least one *display arm, which in turn is pivotally connected to a base. When the *display arm(s) points upward from the base, the *display may hang in a vertical position. When the *display arm is lowered a torque is exerted on the *display to tilt the *display away from the base. When the *display reaches a *horizontal position an open space will exist under the *display that can be used to place items such as a mouse, keyboard, notepad, pens or other low profile devices. One or more feet are attached to the *display such that that when the *display is in the horizontal position the foot or feet contact a stable surface such as a desk, table or other suitably stable object, and further provides for such open space.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Application Ser. No. 61/818,180 filed on May 1, 2013, entitled “Foot Support Assembly For Cantilevered Touch Screen,” the benefit of the earlier filing date of which is hereby claimed under 35 U.S.C. §119 (e) and further incorporated by reference in its entirety.


TECHNICAL INVENTION
Various embodiments relate generally to computer display mounting devices and more particularly, but not exclusively to a foot support assembly that is useable for displays, such as touch screen displays, where the display is tilted away from a central mounting point and held in a cantilevered position, such that the foot is used to support and or elevate the display.
BACKGROUND
Electronic displays with data input capability may be considered as having two distinct usage modes. One usage mode is for information display, while a second usage mode is where a touch screen interaction and display are provided simultaneously. In the first usage mode, the typical computer display involves a standard computer monitor, with an ergonomic design that encourages the display to be at a typical arm's length away from a user and at or slightly below eye level, where a mouse and keyboard are the primary means of user input. However, this position may not be ideal for the second usage mode where touching the screen is intended as a primary method of input. For the second usage mode, the display is often placed closer to the user, lower and in a more horizontal position near the area where the mouse and keyboard are traditionally placed. This can be accomplished by placing the display at the end of an arm and pivoting the arm from an elevated position to a lower position. When in the lower position the display can extend over the keyboard placing it in a cantilevered position at the end of the pivoting arm. When the display is so extended touch input from a user imparts significant strain on the cantilever assembly. The actions of supporting the display in the lower horizontal position are among the considerations, that embodiments of the present invention have been made.

ILLUSTRATIVE EMBODIMENTS
Each of the FIGURES discussed below may include many more or less components than those shown in the FIGURES. Moreover, not all the components may be required to practice various embodiments and variations in the arrangement and type of the components may be made. However, the components shown are sufficient to disclose various illustrative embodiments for practicing the present invention.
FIGS. 1A, 1B and 1D illustrate perspective views of one embodiment of a foot support system attached to a computer display in various angled positions. In one embodiment folding foot assemblies 1A and 1B are rigidly attached to display 14. Display mount 24 is rigidly attached to display 14. The display mount 24 is rigidly attached to cam 15. One or more display arms 17 are pivotally attached to display mount 24. Display arms 17 are pivotally attached base 20. The first end of cable 16 is attached to cam 15 and wraps cam 15. The second end of cable 16 attached tilt adjustment screw 18. Cam 15 is constructed such that cable 16 exerts a torque to rotate the cam 15, display mount 24, and display 14. Cable attachment point to tilt adjustment screw 18 is positioned such that as display arms 17 pivot downward (see FIG. 1A dashed arrow indicating direction of movement), the cable 16 will ‘unwind’ about cam 15, thereby pivoting display mount 24 and display 14 away from base 20. Tilt adjustment screw 18 is threaded into base 20. Tilt adjustment screw 18 adjusts the tilt of display 14 when in horizontal positions FIG. 1B, 22 and FIG. 1D, 23. Display arms 17 are rigidly attached to counterweight 19. Base 20 rests on desk 13 surface.
FIG. 1B shows display 14 in tilted horizontal position 22. Folded footing 1A is contacting desk 13. Footing 1A provides support such that movement of display 14 is minimized when user 25 touches display 14. Footing 1A elevates display 14 and display mount 24 such that there is room beneath display 14 for keyboard 14 or other items.
FIG. 1C illustrate perspective view of one embodiment of foot support system with folding support feet. The foot housing 3 contains folded foot 2 when in the folded position. The foot housing 3 can act as a support foot (as shown in FIG. 1B footing 1A). If a footing with greater elevation is required folded foot 2 may be pivoted about point 5 such that it stops in the unfolded foot 4 position. In one embodiment the foot housing 3 and folded foot 2 are mode of molded plastic with a rubber like slip resistant material in areas were contact with desk 13 is intended. In other embodiments the housing and foot may be made of metal, composites or any other material capable of proving sufficient support, the slip resistant material may omitted.
In one embodiment, folded foot 2 may be pivoted from foot housing 3 to unfolded position 4 by user prying footing loose from housing 3 then pivoting foot to unfolded position 4. In other embodiments, the footing may be press latch locked and pivoting action of foot 4 may be powered by spring.
FIG. 1D shows display 14 in a flat horizontal position 23 with feet 4A and 4B in unfolded position. Display 14 is elevated above keyboard 12 by feet 1A and 1B. Feet 1A and 1B stabilize display 14 from user 25 touch input.
In one embodiment, desk 13 is traditional office desk surface composed of a hard laminate over composite wood surface. However, desk 13 can comprise of any approximately horizontal surface capable holding display base. As shown in later embodiments the surface for supporting the footing assembly need not be a contiguous surface.
Display 14 can be virtually any computer monitor for providing an image to a user, including, but not limited to a liquid crystal display (LCD) device, OLED or the like. In one embodiment, display 14 may be a computer display device that is configured as a touch screen display that enables users to interact and provide inputs to a computing system by touching a screen of the display 14. Display 14 may provide any of a variety of mechanisms for attaching to display mount 24, including, but not limited to bolts, screws, hooks, pin connectors, or the like. For example, in one embodiment a screw element may be employed to attach display 14 to display mount 24. By employing such mechanisms, display 14 may be removed from display mount 24 and/or other display devices may be attached to display mount 24. However, in other embodiments, display 14 may be attached to display mount 24 to not be readily removable. For example, in one embodiment, display 14 may be glued, soldered, welded, or otherwise permanently attached to display mount 24.
In other embodiments, any or all the elements of display arm 17 pivot, horizontal tilt screw 18 and folded feet 4A,4B may be electro mechanically operated such that the user may be able to select pre-programmed display positions including but not limited to vertical FIG. 1A, 21, tilted horizontal FIG. 1B, 22, and flat horizontal FIG. 1D, 23.
In one embodiment, the pivoting connection point between the display 14 and the display arm 17 is located above the display 14 horizontal center as measured when the display 14 surface is parallel to a force of gravity; in the vertical position 21. That is, in one embodiment, the pivot point between a second end of the arm and the computer display device is located above the display device horizontal center as measured when the display device surface is parallel to the force of gravity. This maximizes the open space below display 14 when in the horizontal positions 22 and 23. The pivot point items such as the cam 15, the display mount 24 or the display arm(s) 17 occupy open space below the display 14 when horizontal. By locating the pivot point items above the display 14 mid point it provides adequate open space between pivot point members and footings 1A to store items like keyboard 12, wrist brace 11 or other low profile devices.
Illustrative Operations
The operation of certain aspects of the embodiments will now be described with respect to FIGS. 1A-1D. FIGS. 1A-1D illustrate perspective views of one embodiment of a foot support system attached to a computer display in various angled positions. FIG. 1A illustrates a vertical position 21 for the display 14; FIG. 1B illustrates a tilted horizontal position 22 for the display 14, and FIG. 1D shows a flat horizontal position 23. FIG. 1C illustrates a detailed view of folded feet and related component parts. It should be readily apparent to one of skill in the art that such illustrated positions are non-limiting, and other positions may be obtained when the computer display is rotated about the base, as described further below. Moreover, as stated elsewhere, not all components may be illustrated. For example, the display may be in a tiled horizontal position 22 and feet 4A may be unfolded creating more open space under the display.
In any event, when display 14 is in a vertical position 21, FIG. 1A, display 14 is in its highest elevation, relative to base 22. Again, FIG. 1A illustrates one embodiment of such vertical configuration.
As shown in FIGS. 1B,1D, as display arm 17 is lowered, such as being repositioned downwards towards desk 13 or the like, as display arm 17 is lowered, the cable 16 is positioned such that distance between screw 18 attachment point and tangent point of cable 16 to cam 15 will increase. This imparts a toque on cam 15 to pivot display mount 24 and display 14 away from base 20. When screw 18 is turned it moves the cable 16 attachment point at the end of the screw 18 along the axis of the screw 18 length. Screw 18 is positioned approximately perpendicular to display arm 17 when in the vertical position 24, thus when the cable 16 attachment point is moved relative to the screws axis of length it has very little effect on the display tilt in the vertical position FIG. 1A, 21 but has a much greater effect on horizontal titled position FIG. 1B, 22 and horizontal flat position FIG. 1D, 23.
As shown in FIG. 1B, when the display arm 17 lowers display 14 to the point where folded footing support 1A contacts the desk 13 this stops pivoting action of both display 14 and display arm 17. When folded footing support 1A is in contact with desk 13 and user 25 touches the display 14 a large portion of the downward force exerted on the display 14 is directed to fold footing support 1A. The folded footing support 1A may incorporate a non-skid surface such that any sliding movement caused by the user 25 touch of the display is resisted.
As shown in FIG. 1D, the horizontal tilt screw 18 may be adjusted such that display 14 is pivoted to reach a flat horizontal position 23. The support feet 4a and 4b are unfolded by user 25 such the display is fully supported by feet 4a and 4b. 
Alternative Embodiments
Other embodiments are also envisaged. For example, FIG. 2 illustrates one embodiment of a perspective view of a footing support with tablet display. The first ends of display arms 35 and 36 are both pivotally connected to display holder 38. The second end of display arm 36 is pivotally connected to base 40. The second end of display arm 35 is pivotally connected to tilt adjustment screws 30 and 32. The arrangement and length of display arms 35 and 36 will cause display mount 38 to pivot away from the base 40 when lowered from vertical position 33 the horizontal position 39. In one embodiment a detachable tablet computer 37 may be placed in the display holder 38 in other embodiments a display may be permanently attached to display mount 38.
In one embodiment of FIG. 2 support footing 6 is permanently attached display mount 38. In other embodiments footing 6 may be detached and re-attached to a different location on display mount 38. The removable footing may be attached by glues, suction cups, hook-and-loop fasteners or any other means of rigid connection that is removable and re-attachable.
FIG. 3 shows a sliding footing 7 attached to display mount 38 with telescoping display arm 52. Pivot points 50 of the telescoping display arm 52 may be frictional hinges, detent hinges, spring loaded hinges or any combination thereof. Sliding foot 7 may be adjusted along the path indicated by arrows 57. In one embodiment sliding footing 7 is prevented from sliding by tightening wing nut 56. In other embodiments the footing may be held from sliding by cam locks, magnets or any other means that allows the foot to be adjusted along the length of arrow 57 but held rigidly when in normal use.
FIG. 4 illustrates oblique perspective view of base 63 with legs 61 are rigidly attached to base 63 and extend under display 60. The function of the legs 61 is to prevent base 63 from topping when display 60 is lowered to a horizontal position. Feet 8 elevate display 60 to allow for an open space 64 below display 60 for storage a keyboard, mouse and the like. The non-open space under the display 65 is not as useful as open space 64 because elements of the base can obstruct the usage of keyboard, mouse and the like. Feet 8 provide support for the display 60 such that touch input on the display 60 should not cause the base 63 to topple.
The above specification, examples, and data provide a complete description of the manufacture and use of the composition various embodiments. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
