Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a foldable chair. More
particularly, the present invention relates to a foldable chair
which has a light weight.
[0002] A conventional foldable chair is made of metal. However, the
metal chair is very heavy. Another conventional foldable chair is
made of plastics. However, the plastics chair is not durable.
SUMMARY OF THE INVENTION
[0003] An object of the present invention is to provide a foldable
chair which has a plastics seat pad and a plastics backrest to
reduce a weight of the foldable chair.
[0004] Another object of the present invention is to provide a
foldable chair which is durable after a long period of usage.
[0005] Accordingly, a foldable chair comprises a plastics seat pad,
a plastics backrest, and a chair frame having a pair of metal front
leg tubes and a pair of metal rear leg tubes. Each of the metal
front leg tubes and the corresponding metal rear leg tube are
connected together. The plastics backrest has two lateral posts
inserted in the metal front leg tubes. Two L-shaped frames are
disposed on two sides of the plastics seat pad. Each of the
L-shaped frames is connected to the corresponding metal front leg
tube and the corresponding metal rear leg tube. A plurality of
rivets fasten each of the L-shaped frames on the corresponding
metal rear leg tube and the corresponding metal front leg tube.
Each of the metal front leg tubes has a blocking bar to block the
plastics backrest.
