Description

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a foldable chair, and more particularly to a foldable chair comprising a fabric made chair seat and a foldable frame adapted for folding and unfolding the chair seat, wherein the foldable chair provides a rigid and strong support while it is easy for hand carrying, storage and usage.

2. Description of Related Arts

Foldable chairs are easy to be carried and used both indoor and outdoor. A typical foldable chair comprises a foldable frame and a seat member foldably supported by the foldable frame in such a manner that the chair is capable of folding between a folded condition and an unfolded condition, wherein in the unfolded condition, the foldable frame stands on a ground surface and supports the seat member in a substantially horizontal position for a user to set, and that in the folded condition, the foldable frame can be pivotally and collipsibly folded to form a compact structure for ease of carry and storage.

The conventional foldable chair is usually made of metal or wood, especially when the seat member is made of rigid material, the foldable chair will be relatively heavy and bulky. Furthermore, the rigid chair cannot provide a comfortable and enjoyable seating for a user. In other words, a foldable chair should be employed to provide a relaxing and peaceful seating experience. In addition, the conventional foldable chair often fails to provide a stable support which is prone to flip over when a heavy user sits on the soft pliable seat and is easy to be damaged when a relatively heavy downward force is applied thereo.

In addition, a conventional foldable chair employs armrests for the user to rest his hands, referring to FIG. 1A of the drawing, a foldable chair comprises a rear frame 100, a front frame 200 extended from the rear frame 100, a seat frame 300 for mounting a chair seat 400, wherein the front frame 200 comprises an armrest portion 210 extended from the rear frame 100 and a leg portion 220 inclinedly extended from the armrest portion 210 for standing on a ground surface. Referring to FIG. 1B of the drawing, another foldable chair comprises a seat frame 100′, two leg frames 200′, and two armrests 300′ mounted to the seat frame 100′ and the two leg frames 200′, wherein the two armrests 300′ are supported by the two leg frames 200′. Accordingly, these kinds of foldable chair provide a stable support for the armrest, but a main disadvantage of the conventional foldable chair is that the design of the armrest cannot make the foldable chair be folded to a compact structure.

Therefore, a portable and flexible foldable chair which has a light weight for hand carrying or storing in a trunk of a vehicle when being folded to a compact size as well as enhanced structural strength and stability for using is highly desired. And a pair of armrests is a desired structure for the foldable chair which is preferred to be also constructed foldable to reduce its size in folded condition while providing a rigid and steady support of the user's forearms in unfolded condition.
