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 portable workstation apparatus comprising:
a pair of collapsible legs, each leg of the pair of collapsible legs comprising:
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,

wherein 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, and
a work portion that is attached in a removable manner to the pair of collapsible lags via a pair of brackets.

2. The apparatus of claim 1 , wherein the work portion is height-adjustable.

3. The apparatus of claim 1 , wherein the work portion is a desk portion.

4. The apparatus of claim 1 , further comprising one or more shelves configured to be attached to the pair of collapsible legs and configured to be removed from the pair of collapsible legs.

5. The apparatus of claim 4 , further comprising one or more dividers configured to be installed within respective slots in the shelves.

6. The apparatus of claim 1 , wherein the sleeve is configured to slide onto the lower post when the extension is rotated towards the lower post.

7. The apparatus of claim 1 , wherein the hinge connects the lower post to the upper post via pins and wherein the hinge is provided within a recess of the lower post and a recess of the upper post.

8. The apparatus of claim 1 , wherein each bracket of the pair of brackets comprises an opening and a retaining pin configured to retain the bracket in a hole of the plurality of holes.

9. The apparatus of claim 8 , wherein the retaining pin of the bracket disengages the hole when the bracket is rotated.

10. The apparatus of claim 1 , wherein the frame comprises a post retaining clip configured to retain the upper post when the upper post is collapsed.

11. The apparatus of claim 1 , wherein the lower post and the upper post are substantially perpendicular to the extension.

12. A collapsible leg, comprising:
a frame;
an extension connected to the frame;
a lower post housed within a sleeve;
an upper post;
a hinge connecting the lower post and the upper post; and
a plurality of holes on an exterior face of the lower post or the upper post,
wherein 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.

13. The leg of claim 12 , wherein the sleeve is configured to slide onto the lower post when the extension is rotated towards the lower post.

14. The leg of claim 12 , wherein the hinge connects the lower post to the upper post via pins and wherein the hinge is provided within a recess of the lower post and a recess of the upper post.

15. The leg of claim 12 , wherein the frame comprises a post retaining clip configured to retain the upper post when the upper post is collapsed.

16. The leg of claim 12 , wherein the lower post and the upper post are substantially perpendicular to the extension.

17. 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 pin connecting the first member to the hinge body such that the hinge body is rotatable relative to the first member; and
a second pin connecting 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 body,
the second end of the hinge body extends into the second body,
the axis of the first member and the axis of the second member are aligned when the hinge is in a first position, and
the axis of the first member is parallel to the axis of the second member when the hinge is in a second position.

18. The mechanism of claim 17 , wherein a first end edge of the first member contacts a first end edge of the second member when the hinge is in the first position.

19. The mechanism of claim 18 , wherein 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 second position.

20. The mechanism of claim 17 , wherein a first end edge of the first member is separated from a first end edge of the second member when the hinge is in the second position.
