Abstract

The present invention relates to a rear frame for folding chair using a piston rod.

That is, a piston rod that slides up and down is inherent in the hollow of the rear frame, and the piston rod is connected to a chair alignment member connected to the front frame, so that the piston rod slides when the chair is folded or extended. There is a characteristic.

Description

Rear frame for folding chair using piston rod {A FOLDING REAR CHAIR THE REAG FRAME GUDE A PISTON}

The present invention relates to a rear frame for a folding chair using a piston rod that slides on the upper end of the folding chair.

In general, folding chairs are lightweight and can be folded, so they are easy to carry and can be called chairs that are frequently used in classrooms or in places where many people gather.

A conventional folding chair can be largely divided into a front frame 101 having a backrest 100 and a front support means and a rear frame 103 having a seat plate 102 and a rear support means as shown in FIG. The front frame 101 and the rear frame 103 are connected by a hinge 104.

However, when folding the chair as described above, the front frame 101 is moved to the rear centering around the hinge 104, and overlapped in contact with the rear frame 103, the width of the folding to carry the chair in large quantities Not only does it occupy a lot of volume, but even when several chairs are stacked after folding, they are not level and always remain insecure. In particular, the hinge 104 has a drawback that the damage caused by long-term use is concerned.

The present invention has been made in order to solve the above problems, the purpose is to include a piston rod which slides in the upper end of the rear frame and the upper end of the piston rod is connected to the chair alignment member protruding toward the front frame side, When folding, the front frame is folded inside the rear frame, which greatly reduces the width of the folding and can carry more when transporting.In comparison with the hinged as in the prior art, the piston rod provides that it will not be damaged even if used for a long time. The purpose is to.

Inside the rear frame upper end of the folding chair of the present invention for achieving the above object, and a piston rod fitted into the chair alignment member coupled to both sides of the front frame, between the rear frame and the seat plate frame when the front frame is folded back It has a feature that is coupled 'a' type connecting member to be placed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A backrest 3 is coupled to an upper side of the front frame 2 of the folding chair 1, and a seat plate 5 is placed on an upper surface of the seat frame 4, both sides of the seat plate frame 4 and the front frame 2. Is connected to the hinge rivet (6), and the chair alignment member (7) is coupled to the front frame (2) and rivet (8) above the position of the hinge rivet (6),

Inside the chair alignment member (7) is fitted a piston rod (10) which slides in the rear frame (9), the hinge rivet in the direction of the seat plate frame (4) between the rear frame (9) and the seat plate frame (4) (A) and the 'a' type connecting member 12 welded in the direction of the rear frame 9 is coupled, the closing cap (13 ') in the hole (12') behind the 'a' type connecting member (12) ) Projection 13 'is composed of interference fit.

And the upper end of the piston rod 10 is a rivet hole (10 ') is configured to be drilled to be coupled to the chair alignment member 7 and the rivet (8).

The operation of the present invention configured as described above is as follows.

First, when the folding chair (1) is folded, the piston rod (10) exposed to the outside of the rear frame (9) is inclined between the chair alignment member (7) and the front frame (2) connected to the front frame (2). By being inserted into the rear frame 9 by the rear frame 9 is also inclined backward so that the folding chair 1 is unfolded. In this case, the front frame 2 is rotated about the hinge rivet 6 connected to the seat frame 4, and the seat frame 4 is rotated about the hinge rivet 11 connected to the rear frame 9. .

On the contrary, when the folding chair 1 is folded, the inclination angle of the front frame 2 is reduced so that the piston rod 10 connected to the chair alignment member 7 is exposed to the outside of the rear frame 9 and the front of the rear frame 9 is forward. When the frame 2 is folded, the seat plate frame 4 is placed inside the 'a' type connecting member 12 connected to the rear frame 9.

As described above, the present invention incorporates a piston rod that slides on the upper end of the rear frame of the chair, and the upper end of the piston rod is connected to a chair alignment member protruding toward the side of the front frame. It is folded to greatly reduce the width of the folding can carry a larger amount when transporting, the piston rod acting when folding the chair has an effect such as not broken even if used for a long time.

Claims (2)

In the normal folding chair (1), Inside the upper end of the rear frame (9) of the folding chair (1) and the piston rod (11) fitted into the chair alignment member (7) coupled to both sides of the front frame (2): Piston, characterized in that the 'b' type connecting member 12 is coupled between the rear frame 9 and the seat plate frame 4 so that the rear of the front frame 2 can be placed when the front frame 2 is folded. Rear frame for folding chair using rod. The method of claim 1, The rear frame for the folding chair using a piston rod, characterized in that the rivet hole (10 ') is perforated to be coupled to the chair alignment member (7) and the rivet (8) on the upper end of the piston rod (10).
