ABSTRACT:
BACKGROUND OF THE PRESENT INVENTION
1. Field of Invention
The present invention relates to a foldable chair, and more particularly to a foldable chair equipped with a utility side desk which is foldably and outwardly extended from the foldable chair and serves as an extra side surface, wherein the foldable chair can be quickly and easily folded into a compact unit for carriage and storage and unfolded for use.
2. Description of Related Arts
Referring to
FIG. 1
of the drawings, a conventional portable chair comprises a foldable chair frame constructed by metal tubes and a chair seat B
1
made of durable fabric. The foldable chair frame A
1
comprises a plurality of construction tubes A
11
to construct a back frame A
2
and a seat frame A
3
for supporting the chair seat B
1
. The seat frame A
1
comprises a front pair, a back pair and two side pairs of the construction tubes, wherein each pair of the construction tubes are pivotally connected together where they cross so that the chair frame A
1
can be easily unfolded to provide a rigid cross-support for use and be folded up for storage.
Since such a conventional foldable chair can be easily and quickly unfolded for use and folded into a compact for carriage, a user can carry the foldable chair to everywhere such as campground or beach. However, the user may merely carry an extra foldable table in such a manner that the user can put his or her accessories such as drinks or magazines on the foldable table.

a pair of first and second back frame legs pivotally connected with each other in cross manner to form a “X” structure;
two pairs of side frame legs, each pair comprising a first side crossed leg and a second side crossed leg pivotally connected with each other in a cross manner to form a pivotal “X” structure;
a pair of front lower frame joints for pivotally connecting two lower ends of the two front frame legs with two lower front ends of the side frame legs respectively;
a pair of back lower frame joints for pivotally connecting two lower ends of the two back frame legs with two lower back ends of the side frame legs respectively;
a pair of front frame joints for pivotally connecting two upper ends of the two front frame legs with two upper front ends of the side frame legs respectively;
a pair of back upper frame joints for pivotally connecting two upper ends of the two back frame legs with two upper back ends of the side frame legs respectively; and
the side desk frame comprising a pair of foldable supporting arms pivotally connecting with the second front and back frame legs respectively, a pair of slider joints for pivotally coupling two inner ends of the two supporting arms with the first front and back frame legs, and a pair of pivot arms which are extending outwardly from the seat frame pivotally coupling with two outer ends of the two supporting arms respectively.
