ABSTRACT:
FIELD OF THE INVENTION
The present invention generally relates to a chair, and in particular to a collapsible chair.
BACKGROUND OF THE INVENTION
A chair usually comprises four legs, including two front legs and two rear legs, supporting a seat. Some of the chairs have stiles extending from the rear legs to form a back. No matter a chair has a back or not, the conventional chair is fixed and cannot be collapsed or folded. Thus, the conventional chairs take a great amount of space and are difficult to move. A folding chair comprises legs hinged to each other and the seat thereby allowing partial collapse thereof. However, the collapsed folding chair still occupies a substantial amount of space and the problems discussed above remain.
Thus, it is desired to provide a collapsible chair that overcomes the above problems.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a collapsible chair that may be collapsed when not in use for saving space.
Another object of the present invention is to provide a collapsible chair that is capable of complete collapse for occupying a minimum amount of space.
A further object of the present invention is to provide a collapsible chair that is fully collapsible for facilitating movement thereof.
To achieve the above object, in accordance with the present invention, there is provided a collapsible chair comprising two front legs and two rear legs. Two stiles telescopically received in the rear legs and may be moved to an extended position to form a back of the chair. A collar is movably fit over each leg. A pair of pivoted links is connected between every two adjacent legs. Each link has a first end pivotally attached to one of the two legs and a second end pivotally attached to the collar of the other one of the two legs whereby the chair is collapsed by moving the collars along the legs and the legs converge together. A flexible sheet is releasably fixed to top ends of the legs for serving as a seat. The flexible sheet may be removed from the chair when the chair is collapsed and the collapsed chair may be wrapped by the removed sheet thereby significantly reducing the space occupied by the collapsed chair.
