Abstract

An adjustable stand for rotatably and releaseably supporting a flat panel display is disclosed together with a display device usable with the stand. The display includes a boss projecting from a rear surface thereof, which boss is received in an arc-shaped channel in a plate portion of the stand. The stand further includes two hingedly connected legs and selective locking devices for controlling the angle between the legs, thereby allowing the stand hold the display in a variety of orientations with respect to a horizontal support surface.

Claims

1. In combination, a display and a support stand for adjustably supporting said display,

said display comprising a housing having a front and a rear, a screen mounted on said housing front and a boss projecting from said housing rear;

and

said stand having a bearing surface for receiving said boss and rotatably supporting said display, said stand comprises first and second legs connected by a hinge and said hinge comprises at least one spring clutch,

said stand having a channel with a first end that is open and a second end that is closed,

said boss being slidingly removable from said channel open.

2. The combination of claim 1 wherein said boss is detachably secured to said housing.

3. The combination of claim 1 wherein said boss includes a centerline normal to said display and a generally circular cross section normal to said centerline.

4. The combination of claim 3 wherein said boss includes a first end adjacent said housing and a second end spaced from said housing, said second end including a flange.

5. The combination of claim 1 wherein said bearing surface comprises an arc of a circle.

6. The combination of claim 5 wherein said arc is greater than 180 degrees.

7. The combination of claim 4 wherein said stand comprises a plate member having a thickness, said bearing surface is located in said plate member, and said flange is spaced from said housing by a distance substantially equal to said plate thickness.

8. The combination of claim 6 wherein said circular arc has first and second ends spaced apart by a first distance and said boss has a minor axis shorter than said first distance and a major axis longer than said first distance.

9. The combination of claim 7 wherein said bearing surface has first and second ends and said plate member includes first and second walls extending from said first and second ends.

10. The combination of claim 1 wherein said boss is centrally located on the housing rear.

11. The combination of claim 1 wherein said housing is rotatable on said stand between a portrait orientation and a landscape orientation.

12. The combination of claim 1 including a stop for limiting the rotation of said display with respect to said stand.

13. The combination of claim 11 including at least one stop for selectively holding said housing in either said portrait or said landscape orientation.

14. The combination of claim 1 wherein said hinge is selectively lockable in at least two positions.

15. The combination of claim 1 wherein said hinge comprises a balance spring.

16. The combination of claim 15 wherein said first leg lies generally in a first plane, said second leg lies generally in a second plane and wherein said hinge is shiftable between a first position wherein said first leg and said second leg meet at an obtuse angle and a second position wherein said first leg and said second leg meet at an acute angle.

17. The combination of claim 16 wherein said obtuse angle is between about 140 degrees and 180 degrees and said acute angle is between about 20 degrees and 60 degrees.

18. The combination of claim 1 including at least one lever for shifting said at least one spring clutch between an engaged position and a disengaged position.

19. The combination of claim 18 wherein said at least one spring clutch comprises first and second oppositely mounted spring clutches.

20. The combination of claim 1 wherein a portion of said first leg is covered with a high friction material and wherein a portion of said second leg is covered with a low friction material.

21. The combination of claim 1 wherein said hinge is lockable to prevent an angle between said first and second legs from increasing.

22. The combination of claim 1 wherein said hinge is lockable to prevent the angle between said first and second legs from decreasing.

23. The combination of claim 1 wherein said hinge includes a first lock for preventing the angle between said first and second legs from increasing, a second lock for preventing the angle between said first and second legs from decreasing, and at least one actuator for releasing said first or said second lock.

24. The combination of claim 1 wherein said boss has a T-shaped cross section.

25. In combination, a display and a support stand for adjustably supporting said display,

said display comprising a housing having a front and a rear, a screen mounted on said housing front and a boss projecting from said housing rear;

and

said stand having a bearing surface for receiving said boss and rotatably supporting said display,

said stand having a channel with a first end that is open and a second end that is closed, said boss being slidingly removable from said channel open end, said channel is substantially circular, said channel subtends an arc in excess of 180°

, said first open end has spaced first and second opposed terminal ends and a linear peripheral portion extends adjacently outwardly from each of said terminal ends.

26. The combination of claim 25, wherein said channel has a first width at said open end, a second width at a longitudinal midpoint, and a third width adjacent said channel closed end,

said first width being narrower than said second width, said second width being greater than said first and third widths.

27. The combination of claim 25, wherein said channel is substantially vertical when said stand vertically supports said display, said channel closed end having a vertically lower position than said channel open end.

28. The combination of claim 25, wherein said channel width is narrower than said boss width.

29. The combination of claim 25, wherein said channel centerline coincides with said stand centerline.
