The frame has main bars, curved rear legs, curved front legs, sleeves, armrests, front scissored bars, rear scissored bars, and supporters. The chair can be folded and expanded smoothly with fewer slidable means. The technical effects of the invention are a compact and durable foldable beach chair that is easy to store and use."

Problems solved by technology

A drawback of these foldable chairs is that their legs are not strong enough since the straight structure.
Furthermore, the aforementioned foldable chair has too many slidable means which is made up of a sleeve and a tube contained therein.
The slidable means makes an operation of folding and expanding of the chair not smooth enough.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a foldable beach chair, and more particularly, to a foldable beach chair which has a small storage volume but strong structure, and which has few slidable means thus being able to be folded and expanded smoothly.[0003]2. Description of the Prior Art[0004]A foldable chair is disclosed in a U.S. patent application Ser. No. 12,007,612. As most of the conventional foldable chairs, the chair has straight legs. A drawback of these foldable chairs is that their legs are not strong enough since the straight structure. Furthermore, the aforementioned foldable chair has too many slidable means which is made up of a sleeve and a tube contained therein. The slidable means makes an operation of folding and expanding of the chair not smooth enough.BRIEF SUMMARY OF THE INVENTION[0005]The main object of the invention is to provide a foldable beach chair which is able to be folded into a small storage volume and...
