Abstract

A portable workstation apparatus includes: a pair of collapsible legs; and a work portion that is attached in a removable manner to the pair of collapsible lags via a pair of brackets. Each leg of the pair of collapsible legs includes: a frame; an extension connected to a first end of the frame; a lower post housed within a sleeve; an upper post; a hinge connecting the lower post and the upper post; a first brace connecting the extension to the sleeve; and a plurality of holes on an exterior face of the lower post or the upper post. Each leg is configured to collapse by folding the upper post towards the lower post via the hinge and rotating the extension toward the lower post.

First claim

What is claimed is:

1. A hinge mechanism, comprising:
a hinge body having a first end and a second end;
a first member having an axis;
a second member having an axis;
a first connection portion that connects the first member to the hinge body such that the hinge body is rotatable relative to the first member; and
a second connection portion that connects the second member to the hinge body such that the hinge body is rotatable relative to the second member,
wherein the first end of the hinge body extends into the first member,
the second end of the hinge body extends into the second member, and
the axis of the first member and the axis of the second member are aligned when the hinge is in an aligned position.

2. The mechanism of claim 1 , wherein a first end edge of the first member contacts a first end edge of the second member when the hinge is in the aligned position.

3. The mechanism of claim 2 , wherein the axis of the first member and the axis of the second member are in a non-aligned orientation when the hinge is in a non-aligned position, and
the first end edge of the first member is separated from the first end edge of the second member when the hinge is in the non-aligned position.

4. The mechanism of claim 1 , wherein the axis of the first member and the axis of the second member are in a non-aligned orientation when the hinge is in a non-aligned position.

5. The mechanism of claim 4 , wherein a first end edge of the first member contacts a first end edge of the second member when the hinge is in the aligned position.

6. The mechanism of claim 1 , wherein the first connection portion is a first connector, and the second connection portion is a second connector.

7. The mechanism of claim 6 , wherein the first connector extends into an opening in the first member.

8. The mechanism of claim 1 , wherein the first end of the hinge body comprises a radiused corner.

9. The mechanism of claim 8 , wherein the second end of the hinge body comprises a radiused corner.

10. The mechanism of claim 1 , wherein the first connection portion is a first pin, and the second connection portion is a second pin.

11. A hinge mechanism, comprising:
a hinge body having a first end and a second end;
a first member having an axis;
a second member having an axis;
a first connection portion connecting the first member to the hinge body; and
a second connection portion connecting the second member to the hinge body,
wherein the first end of the hinge body is located in a recess in the first member,
the second end of the hinge body is located in a recess in the second member,
the first member is rotatable relative to the hinge body and the second member is rotatable relative to the hinge body such that the first member is rotatable between a first position in which the axis of the first member and the axis of the second member are aligned and a second position in which the axis of the first member and the axis of the second member are not aligned.

12. The mechanism of claim 11 , wherein a first end edge of the first member contacts a first end edge of the second member in the first position.

13. The mechanism of claim 12 , wherein the first end edge of the first member is separated from the first end edge of the second member in the second position.

14. The mechanism of claim 11 , wherein a first end edge of the first member is separated from a first end edge of the second member in the second position.

15. The mechanism of claim 11 , wherein the first connection portion is a first connector, and the second connection portion is a second connector.

16. The mechanism of claim 15 , wherein the first connector extends into an opening in the first member.

17. The mechanism of claim 11 , wherein the first end of the hinge body comprises a radiused corner, and the second end of the hinge body comprises a radiused corner.

18. The mechanism of claim 11 , wherein the first connection portion is a first pin, and the second connection portion is a second pin.

19. A hinge mechanism, comprising:
a hinge body having a first end and a second end;
a first member having an open end and an axis;
a second member having an open end and an axis;
a first connection portion connecting the open end of the first member to the hinge body; and
a second connection portion connecting the open end of the second member to the hinge body,
wherein the first member is rotatable relative to the hinge body,
the second member is rotatable relative to the hinge body,
the axis of the first member and the axis of the second member are aligned when the hinge is in an aligned position.

20. The mechanism of claim 19 , wherein the axis of the first member and the axis of the second member are in a non-aligned orientation when the hinge is in a non-aligned position.
