ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a portable, foldable chair. More specifically, the present invention relates to a portable, foldable chair which has a pair of arm rests with cup holders, a leg rest adjustably assembled to the frame, and a head rest adjustably assembled to the frame.
BACKGROUND OF THE INVENTION
A portable, foldable chair is very useful in a garden of a house, or outdoors. In this specification, a portable, foldable chair is called “a foldable chair” hereinafter. A foldable chair is usually assembled with a chair frame made of hollow steel pipes and a seat cloth assembled thereon. Of course, the chair frame can be made of various materials such as hollow plastic pipes or hollow aluminium pipes as well as hollow steel pipes. The seat cloth is a woven fabric of a sufficient strength. The Oxford cloth woven with nylon 6 filament yarn is preferably used for the seat cloth.
Conventional foldable chairs are not comfortable because they consist of a foldable frame and a seat cloth assembled thereon. In other words, conventional foldable chairs are not equipped with a pair of arm rests which would make the user comfortable when seated. Although arm rests are very popular components in regular chairs. In particular, as a foldable chair is used when taking a rest in a garden or outdoors, it is important to equip the foldable chair with a pair of arm rests.
Accordingly, a need exists for a portable, foldable chair which can be used comfortably and conveniently and, which can overcome the drawbacks of conventional foldable chairs.
OBJECTS OF THE INVENTION
An object of the present invention is to provide a foldable chair having a pair of arm rests with a cup holder, which is comfortable and useful.
Another object of the present invention is to provide a foldable chair adjustably assembled with a leg rest which can make the user comfortable by stretching the user's legs when taking a rest.
A further object of the present invention is to provide a foldable chair adjustably assembled with a leg rest which can be easily disassembled from and assembled to the frame of the foldable chair, and is not easily disassembled from the frame during use, in other words, when the foldable chair is unfolded.
A further object of the present invention is to provide a foldable chair further comprising a head rest which is adjustable.
The above and other objects of this invention may be accomplished by the following description of this invention.
