Device with a rotatable display
The description relates to devices, such as computing devices having displays that can be rotated through a range of travel. The device can counter-balance the display to create a near weightless feel for the user when repositioning the display.
1. A device, comprising:
a base assembly including a processor and a base shaft configured to define a lower axis of rotation;
a display assembly including a display that is driven by the processor, the display secured by a display mount relative to a display shaft that is configured to define an upper axis of rotation;
a hollow arm secured to the base shaft and the display shaft;
a lower link positioned within the hollow arm and secured to the base assembly; and,
an upper link positioned within the hollow arm and secured to the display mount.
2. The device of claim 1 , wherein the lower link defines a range of rotation of the hollow arm at the lower axis of rotation.
3. The device of claim 2 , wherein the lower link and the upper link are configured to secure two additional links that extend between the lower link and the upper link.
4. The device of claim 3 , wherein the lower link includes first and second fasteners for receiving the two additional links.
5. The device of claim 4 , wherein the first and second fasteners and the lower axis of rotation lie along a single line.
6. The device of claim 4 , wherein the first and second fasteners and the lower axis of rotation form an obtuse angle relative to the display assembly where the lower axis of rotation comprises a vertex of the obtuse angle.
7. The device of claim 3 , wherein the upper link includes third and fourth fasteners for receiving the two additional links.
8. The device of claim 7 , wherein the third and fourth fasteners and the upper axis of rotation lie along a single line.
9. The device of claim 7 , wherein the third and fourth fasteners and the upper axis of rotation form an obtuse angle relative to the base assembly where the upper axis of rotation comprises a vertex of the obtuse angle.
10. The device of claim 1 , wherein the upper link defines a range of rotation of the hollow arm at the upper axis of rotation.
11. A device, comprising:
a base assembly including a base shaft configured to define a lower axis of rotation;
a display assembly including a display mount securing a display and rotatably secured to a display shaft that is configured to define an upper axis of rotation;
a hollow arm secured to the base shaft and the display shaft;
a lower link positioned within the hollow arm and fixedly secured to the base assembly; and,
an upper link positioned within the hollow arm and fixedly secured to the display mount, wherein the hollow arm rotates with the base shaft while the lower link is stationary and the upper link rotates with the display mount.
12. The device of claim 11 , wherein the lower link defines stops that limit a range of travel of the hollow arm relative to the base assembly and wherein the upper link defines stops that limit a range of travel of the hollow arm relative to the display assembly.
13. The device of claim 11 , wherein the hollow arm defines an upper hub attached to the upper axis of rotation and a lower hub attached to the lower axis of rotation.
14. The device of claim 13 , wherein the lower link passes between spokes of the lower hub to attach to the base assembly.
15. The device of claim 14 , wherein angular distance between the spokes and the lower link defines a range of rotation of the hollow arm relative to the base assembly.
16. The device of claim 13 , wherein the upper link passes between spokes of the upper hub to attach to the display mount.
17. The device of claim 16 , wherein angular distance between the spokes and the upper link defines a range of rotation of the hollow arm relative to the display.
18. A device, comprising:
a base assembly including a base shaft configured to define a lower axis of rotation;
a display mount secured to a display and rotatably secured to a display shaft that is configured to define an upper axis of rotation;
a hollow arm including an upper hub attached to the display shaft and a lower hub attached to the base shaft;
a lower link positioned within the lower hub and fixedly secured through the lower hub to the base assembly; and,
an upper link positioned within the upper hub and fixedly secured through the upper hub to the display mount.
19. The device of claim 18 , wherein the lower link defines stops that limit a range of travel of the hollow arm relative to the base assembly.
20. The device of claim 18 , wherein the upper link defines stops that limit a range of travel of the hollow arm relative to the display.
21. The device of claim 18 , wherein the lower hub includes spokes and wherein the lower link extends between the spokes to the base assembly.
