Abstract

A reclining chair (10), having a frame (16) including first and second angled members (32) and first and second upright members (34). A support surface (18) has a back portion (15) which is held in position by the first and second upright members (34). Each of the first and second upright members (34) is attached to one of first and second angled members (32) by reversible joints (39), so that the reclining chair (10) is movable from an upright position (12) when the reversible joints (39) are in a first position, to a reclining position (14) when the reversible joints (39) have been reversed to a second position.

Also a collapsible reclining chair (100).

15. The portable reclining chair as in claim 13, further comprising armrests.

16. The portable reclining chair as in claim 13, wherein said chair is collapsible.

18. The portable reclining chair as in claim 17, wherein each of said reversible joints comprise:

an extension member having first and second ends;

a sleeve housing having a sleeve pivot, said sleeve housing being attached to one of said angled members;

a pivot housing having first and second pivots; and

said lower end of one of said upright members being pivotally attached to said first pivot of said pivot housing, said first end of said extension member being pivotally attached to said second pivot of said pivot housing, said second end of said extension member being pivotally attached to said sleeve pivot of said sleeve housing.

19. The portable reclining chair as in claim 17, wherein each of said reversible joints comprise:

a pivot housing having first and second pivots; and

said lower end of one of said upright members being pivotally attached to said first pivot of said pivot housing, said second pivot of said pivot housing being pivotally attached to one of said angled members.

20. The portable reclining chair as in claim 17, further comprising a footrest.

21. The portable reclining chair as in claim 17, further comprising armrests.

22. The portable reclining chair as in claim 21, wherein:

said armrests are pivotally attached to said upright members and which pivot when said chair is moved from said upright position to said reclining position so that they remain roughly horizontal.

23. The portable reclining chair as in claim 17, further comprising:

upper angled members which are pivotally attached to said upright members, and which pivot when said chair is moved from said upright position to said reclining position.

24. The portable reclining chair as in claim 17, wherein said chair is collapsible.

26. The collapsible reclining chair as in claim 25, wherein each of said reversible joints comprise:

an extension member having first and second ends;
