Abstract

A folding chair has a seat 2, a backrest 2, a pair of armrest plates 3, a pair of front joints 31, a pair of hollow connectors 5, a pair of cantilever arms 4, a pair of end blocks 6, a pair of rear rods 13, a pair of front rods 12, a pair of lower rods 17, four connecting disks 16, and four pedestal mounts 14. Each hollow connector 5 engages with the cantilever arm 4. Each armrest plate 3 passes through the corresponding hollow connector 5. Each cantilever arm 4 has a proximal collar 40. Two ends of each armrest plate 3 are connected to the corresponding front joint 31 and the corresponding end block 6. The connecting disks 16 are disposed on a bottom of the seat 1.
Each rear rod 13 passes through the corresponding con-necting disk 16 and the corresponding proximal collar 40.
Each rear rod 13 is disposed on the corresponding pedestal mount 14. Each front rod 12 passes through the correspond-ing connecting disk 16 and the seat 1 to engage with the corresponding front joint 31. Each lower rod 17 is inserted in the corresponding front rod 12 and disposed on the corresponding pedestal mount 14.

Description

TITLE: FOLDING CRAIR
The present invention relates to a folding chair.
More particularly, the present invention relates to a folding chair which is operated easily.
A conventional folding chair has two fixed armrests.
05 Since the fixed armrests cannot be folded, the conven tional folding chair will occupy a large room while folding.
An object of the present invention is to provide a folding chair which is operated easily.
FIG. 1 is a perspective exploded view of a folding chair of a preferred embodiment in accordance with the present invention;
FIG. 2 is a perspective assembly view of a folding chair of a preferred embodiment in accordance with the present invention;
FIG. 3 is a schematic view illustrating an armrest plate, a front rod, and a rear rod are extended;
FIG. 4 is a schematic view illustrating a folding operation of a foiding chair while folding;
FIG. 5 is a schematic view illustrating a hollow connector and a cantilever arm are detached;
FIG. 6 is a schematic view illustrating a folding chair is folded;
FIG. 6A is a partially enlarged view of FIG. 6; and FIG. 7 is a partially sectional view of FIG. 6.

Referring to FIGS. 1 to 7, a folding chair comprises a seat 1, a backrest 2 connected to the seat 1, a pair of armrest plates 3, a pair of front joints 31, a pair of hollow connectors 5, a pair of cantilever arms 4, a 05 pair of end blocks 6, a pair of rear rods 13, a pair of front rods 12, a pair of lower rods 17, a pair of rings 18, four connecting disks 16, four pedestal mounts 14, a male joint 71, a female joint 72, and a plurality of crossing rods 11.
Each hollow connector 5 has a protruded block 51.
Each armrest plate 3 passes through the corresponding hollow connector 5.
Each cantilever arm 4 has a proximal collar 40 and two downward lugs 41 to engage with the protruded block 51. A rivet 15 fastens the downward lugs 41 and the protruded block 51 together.
Two ends of each armrest plate 3 are connected to the corresponding front joint 31 and the corresponding end block 6.
2Q The connecting disks 16 are disposed on a bottom of the seat 1.
Each rear rod 13 passes through the corresponding connecting disk 16 and the corresponding proximal collar 40.
Each rear rod 13 is disposed on the corresponding pedestal mount 14. A rivet 15 fastens the rear rod 13 and the corresponding pedestal mount 14 together.
Each front rod 12 passes through the corresponding connecting disk 16 and the seat 1 to engage with the 05 corresponding front joint 31. A rivet 15 fastens the front rod 12 and the corresponding front joint 31 together.
Each lower rod 17 is inserted in the corresponding front rod 12.
Each lower rod 17 is disposed on the corresponding pedestal mount 14. A rivet 15 fastens the lower rod 17 and the corresponding pedestal mount 14 together.
One crossing rod 11 passes through the male joint 71 and is connected to the corresponding connecting disk 16 and the corresponding pedestal mount 14.
The other crossing rods 11 passes through the female joint 72 and is connected to the corresponding connecting disk 16 and the corresponding pedestal mount 14.
The male joint 71 engages with the female joint 72.
A rivat 15 faster_s the male joint 71 and the female joint 72 together.
Two rings 18 each is disposed orl a bottom of the corresponding front rod 12 to confine the corresponding lower rod '7.
Each end block 6 has a distal clamp 61.

When the folding chair is folded, each lower rod 17 is extended (as shown in FIG. 6).
When the armrest plates 3 are folded, the folding chair is folded into a compact configuration (as shown 05 in FIG. 6).
