Abstract

A footrest has a platform with an upper surface for supporting a user'"'"'s feet above a ground surface. The footrest is supported by a base portion on the ground surface. An intermediate member is rotatably coupled to the base portion and to the platform for relative rotation about first and second axes, respectively. The first and second axes are offset from each other so that selective rotations about said first and second axes provide for height and orientation adjustment of the platform relative to the ground surface.

Claims

1. A footrest for supporting the feet of a user above a support surface comprising:

a base for supporting the footrest on the support surface; and

at least one intermediate member having a peripheral outer edge surface, the peripheral outer edge surface rotatably supported by a base surface and slidably interfitted with a portion of the base allowing for relative rotation about a first axis; and

a platform having an upper surface for accommodating the feet of the user, the platform rotatably coupled to the intermediate member for relative rotation about a second axis offset from the first axis so that selective rotations about the first and second axes provide for height and orientation adjustment of the upper surface of the platform relative to the support surface.

2. The footrest of claim 1, wherein the first and second axes are parallel.

3. The footrest of claim 2, wherein there are a left and a right such intermediate members positioned adjacent left and right sides of the platform.

4. The footrest of claim 3, wherein the base comprises left and right base portions engaging the left and right intermediate members, respectively.

5. The footrest of claim 4, wherein the base further comprises a cross member connecting the left and right base portions.

6. The footrest of claim 4, wherein each of the left and right base portions comprises a lateral tongue riding on a curved slot having the first axis as its axis of curvature.

7. The footrest of claim 6, wherein the lateral tongues point outward away from the platform.

8. The footrest of claim 4, wherein the left and right intermediate members have a generally circular perimeter portion.

9. The footrest of claim 4, further comprising a cross member connecting the left and right intermediate members.

10. The footrest of claim 3, further comprising locking means for selectively restricting relative rotation of the platform and the left and right intermediate members.

11. The footrest of claim 10, wherein the locking means comprises a shaft engaged to the platform and passing through a slot in one of said left and right intermediate members, a knob engaged to the shaft, and means for causing the knob to bear against the one intermediate member to securely engage the one intermediate member for resisting relative rotation of the one intermediate member and the platform.

12. The footrest of claim 11 wherein the knob is threaded to enable it to be tightened against the intermediate member.

13. A footrest for supporting the feet of a user above a support surface comprising:

a base;

at least one intermediate member having at least a generally circular perimeter edge portion, the generally circular perimeter edge portion supported by a concave base surface and slidably interfitted with the concave base surface allowing for rotation of the intermediate member relative to the base about a first axis; and

a platform having an upper surface for accommodating the feet of the user, the platform rotatably coupled to the intermediate member about a second axis offset from the first axis for rotating in relation to the intermediate member.

14. The footrest of claim 13, wherein the second axis laterally spans the platform, and wherein said second axis is parallel to the first axis.

15. The footrest of claim 13, wherein the base further comprises a tongue, and the intermediate member generally circular perimeter portion further comprises a curved slot curved about the first axis, wherein the tongue rides on the curved slot for guiding the rotation of the intermediate member relative to the base.

16. The footrest of claim 13, further comprising a means for selectively restricting the rotation of the platform relative to the intermediate member.

17. The footrest of claim 13, further comprising means for selectively restricting the rotation of the intermediate member relative to the base.

18. A footrest for supporting the feet of a user above a support surface comprising:

a base for supporting the footrest on the support surface comprising left and right base portions and a locking member;

left and right intermediate members having a generally circular perimeter portion rotatably coupled respectively to the left and right base portions allowing for relative rotation about a first axis;

a plurality of locking features located on the circular perimeter portion of one member of the left and right intermediate members, the locking features engageable with the locking member of the base for restricting rotation of the one member relative to the base; and

a platform having an upper surface for accommodating the feet of the user, the platform positioned between the intermediate members and rotatably coupled to the intermediate members for relative rotation about a second axis offset in parallel from the first axis so that selective rotations about the first and second axes provide for height and orientation adjustment of the upper surface of the platform relative to the support surface.

19. The footrest of claim 18, wherein the locking features comprise laterally extending slots.

20. The footrest of claim 19, wherein the locking member comprises a lever pivotally connected to the base and having a finger engageable with said plurality of locking features.
