Description

[Detailed description of the invention] This invention relates to a folding chair that can freely adjust the height of the seat of the chair.

Until now, there have been various chairs that can be folded or seats that can be adjusted freely in height, but there is one chair that has the above two effects, namely:
There was no chair that could adjust the height of the seat and fold the chair freely.

The purpose of this invention is to provide a folding chair in which the height of the seat can be adjusted and the seat can be folded.

That is, this invention forms a gap part 1 extending in the vertical direction in a plate body, and a base body 2 serving as a front leg at the bottom;
a rotatable rear leg 3 attached to an appropriate position on the back surface of the base body 2; a seat part 5 having a stopper 4 fixed on the surface of the base body 2 and engaging in the gap 1 for raising and lowering; This relates to a folding chair with a seat that can be raised or lowered.

The configuration of this invention will be explained with reference to the drawings.

Fig. 1 is a perspective view showing an embodiment of this invention, Fig. 2 is a sectional view taken along line A-A in Fig. 1, Fig. 3 is an exploded perspective view of Fig. 1, and Fig. 4 is a side view of the folded state. It is a diagram.

The base body 2 is formed by connecting the upper, lower, and middle parts of the three plates that make up the base body 2 in the horizontal direction with a connecting rod 9.
A thick metal ring 10 inserted into a connecting rod 9 is provided adjacent to each plate, and two gap portions 1 are formed in the base body 2 extending in the vertical direction. The upper part of the base body 2 has a grip part 11 for carrying, and below the grip part 11 is a horizontal rod 6 of a stopper 4, which will be described later.
A hole 8 is formed in which the material can be hooked and removed. The hole 8 and the gap 1 communicate with each other. Attached to the back of the base body 2 are rear legs 3 that can rotate to keep the legs open, and the base body 2 below this attachment position acts as a front leg. The length of the rear legs 3 is approximately the same as the length of the front legs, and is made of angle material. A pair of angle members are attached symmetrically so that one piece of the angle member can be inserted into the gap 1.

12 is a horizontal rod attached to the lower end of the angle member.

The seat portion 5 is formed by joining three plates together through a pair of guide rods 7, 7 that penetrate through each of the gap portions 1 and are movable up and down, and is fixed to the guide rods 7, 7. are doing. One ends of the pair of guide rods 7, 7 protruding from the seat portion 5, that is, the portions penetrating the gap portions 1, 1, are bent upward, and the tips protrude toward the back side of the base body 2. ing. This tip comrade or seat 5
A transverse rod 6' or 6, which is to bridge adjacent parts of the guide rods 7, 7, passes through each guide rod 7,7. The horizontal rods 6, 6' can come into contact with the front and back surfaces of the inclined base body 2 when the rear legs 3 are fully opened. Further, the outer peripheries of the horizontal rods 6, 6' are covered with synthetic rubber.

As is clear, the fixation of the seat 5 to the base body 2 is made possible by means of a stopper 4 consisting of transverse rods 6, 6' and guide rods 7, 7.

This invention consists of the above-mentioned structure, and the operation and effect will be explained next.

As shown in FIG. 1, when the rear legs 3 are in an open state, the base body 2 is tilted, and the horizontal rods 6, 6' are in contact with the front and back surfaces of this base body, as well as in the upper and lower positions, so that the seat part 5 is prevented from descending. It's getting old.

In addition, when sitting on the seat 5, simply press the horizontal lever 6,
6' abuts the base body 2, but each transverse rod 6,
6' presses in a different direction, so it does not descend.
In particular, the horizontal bars 6 and 6' of this invention are coated with synthetic rubber, so they have good adhesion to the base 2, and the seat 5
is stable.

Next, in order to move the position of the seat 5, the seat is lifted in the direction of the arrow shown in FIG. 2, thereby releasing the contact between the cross members 6 and 6' and allowing the seat to move up and down freely. By releasing the seat 5 at an arbitrary position, the transverse rods 6, 6' come into contact with the base body 2 again.

Therefore, the range of vertical movement of the seat 5 relative to the base 2 is above the point where the rear legs 3 are fixed to the base 2 (range B), and within this range, the height of the seat 5 is freely adjustable. It is extremely easy to set the height, and anyone can easily set the height. Moreover, once the position of the seat part 5 is set, the seat part 5 relative to the base body 2
Since the adhesion is good, there is no fear of falling during use, and it is extremely stable.

In order to fold the chair of this invention, not only do the rear legs 3 close, but also the horizontal rods 6' are removed from the holes 8.
After removal, by reversing the seat 5, the horizontal rod 6' can be hooked into the hole as shown in FIG.
It has a compact shape that is low in bulk and easy to organize.

As stated above, this idea is an extremely practical and innovative idea because it combines the two effects of being able to freely set the height of the seat and being foldable into a single chair.
