[0017]

The present invention will be described in detail below with reference to the accompanying drawings. The chair according to the present invention has a backrest (1
0) and the seat plate (20) are connected and installed, and in a chair in which the front and rear support legs (30) (40) are provided on both sides of the seat plate (20), the front and rear directions are located below the seat plate (20). It is configured by providing an auxiliary seat plate (50) that can be moved to the inside.

As shown in FIGS. 2 and 3, the auxiliary seat plate (50) is constructed by stretching a seat (53) on an outer frame (51) and a horizontal rod (52). The outer frame (51) is in the form of a hollow pipe, and has openings at both ends (51).
a) is open. Guide bars (54) separated by spacers (22) are arranged on both sides of the rear end of the outer frame (21) of the seat plate (20) to open the outer frame (51) of the auxiliary seat plate (50). By slidably inserting the guide bar (54) from the (51a) side,
An auxiliary seat plate (50) is installed so as to be movable in the front-rear direction. A guider (23) is attached to both sides of the outer frame (21) of the seat plate (20) to support the auxiliary seat plate (5).
The outer frame (51) of (0) is movable in the front-rear direction inside the guider (23).

The diameter of the guide bar (54) is made larger than the diameter of the outer frame (51) so that the guide bar (5)
The outer frame (51) may be configured to be slidable inside 1). Further, the outer lower part of the outer frame (11) of the backrest (10) is rotatably connected to both sides of the outer frame (21) of the seat plate (20) around the hinge fixing parts (12), respectively. 30) and the upper tips of the rear supporting legs (40) are hinged so as to be expanded or folded around the hinge fixing portion (31), and the middle portion of the front supporting legs (30) is connected to the frame (21) of the seat plate (20). )
Is hinged so that it can rotate about the middle part of the hinge and the hinge fixing part (32).

At this time, at the middle portion of the outer frame (11), as shown in FIGS. 1, 10, 13 and 14, one side end of the armrests (60) (60) has hinge portions (6).
1) A hinged connection centered on (61), armrest (60)
An angle adjusting plate (70) having a plurality of lock grooves (71) and a moving opening (72) communicating with each other at the bottom of the (60).
The spacer (33) provided inside the upper hinge fixing part (31) of the front support leg (30) and the rear support leg (40) is inserted and coupled to the movement opening port (72) of the angle adjusting plate (70). Are arranged in a closed state.

Therefore, with the armrests (60) (60) slightly raised around the hinges (61) (61) and the spacer (33) positioned at the movement opening (72), the backrest (10 ) By adjusting the front-rear angle about the hinge portion (12) so that the spacer (33) is positioned at the proper position in the movement opening (72) and is inserted at the proper position in the many lock grooves (71). When the armrests (60) and (60) are placed so as to be installed, the spacer (33) is engaged with the lock groove (71) at the proper position and the backrest (10) is set at the proper angular position.

Further, as shown in FIGS. 4 and 5, the hinge portion (12) of the outer frame (11) is provided with a stopper (80) having a supporting bent step portion (81) on one side and on the other side. Is axially installed together with the hinge part (41) via the rear supporting leg (40) and the reinforcing plate (82), and the outer frame (11) of the backrest (10) is armrested (50) around the hinge part (12). )
Even when the angle is adjusted by the (50) and the angle adjusting plates (70), (70), one side of the rear supporting leg (40) is stably supported by the supporting bent portion (81) and the backrest (10). And the rear supporting leg (40) play a supporting and reinforcing role.

Incidentally, the hinge portions (12) (32) to which a load force is mainly applied when being deployed and used.
(41) is reinforced by fixing the reinforcing plate (82) to the outer peripheral edge of the outer frame (11) (21) or the front and rear supporting legs (30) (40) by welding. As shown in the drawing, the reinforcing plate (82) is simultaneously passed on both sides, or as shown in FIG. 7, only one side is passed through the reinforcing plate (82) for reinforcement.

The outer frames (11) (21) (5)
1) and the front and rear support legs (30) (40) are made of a light and relatively strong material such as aluminum alloy, but at these bent parts, as shown in FIG. The strength is improved by forcibly forming the recesses (83) and (84) respectively. Further, the outer frame (11) (21) (51) and the end portion of the guide bar (54) form a contracted end portion (85) in the form of a reduced tube by firing as shown in FIG. This frees the user from the trouble of inserting and fixing a separate material (for example, a plastic injection material) as in the conventional case. Also, FIG.
The outer frames (21) face each other as shown in FIG.

Next, seats (13) and (53) used for the backrest (10), seat plate (20) and auxiliary seat plate (50) will be described with reference to FIGS. The outer shape of the sheets (13) (53) is a normal form, but the hooks (13a) (13b) (13c) (53) are provided at both ends and the center.
a) and (53c) are respectively bent and formed, and hook portions (13a) (1
3c) (53a) is bent at both ends (86a) (86
A through hole (11a) formed in the outer frames (11), (21) and (51) by inserting the support member (8b) having a).
(21a) (51a) bent end (86a) (86a)
Is inserted and connected, and a support rod (87) is inserted into the hook portions (13b) (53b), and the connecting hole (88) formed in the hook portions (13b) (53b) and the outer frame (21) or A large number of springs (89) are suspended between the through holes (21b) (52a) formed in the horizontal rod (52) and the seat (1
3) Extend (53) in parallel.

Also, the outer frame (1) of the backrest (10)
In 1), as shown in FIGS. 14 and 15, a parasol hook (90) is provided, and a parasol (91) is inserted when necessary. When the chair is folded and stored, the parasol (91) is extracted from the parasol rack (90) and folded and stored in a usual manner as shown in FIG.

[0027]

As described above in detail, the chair according to the present invention is provided with an auxiliary seating plate which can be moved forward and backward in the lower part of the seating plate of the chair, and can be easily used by the user when necessary. You can rest more comfortably. In addition, the angle adjustment plate installed at the bottom of the armrest allows the inclination angle of the backrest to be adjusted as desired, which simplifies the seat connection structure and facilitates assembly work, and improves the comfort of the spring. be able to.

Further, by providing a reinforcing structure to the frame frame, it is possible to improve the strength and secure the easiness of finishing treatment.
