Description

The present invention relates to furniture, and more particularly to an elastic chair that has excellent elasticity because it is made of a combination of bamboo materials, and that is compatible with human body engineering.

For any chair of any kind, the structure includes a bottom, a support, and a seat. The bottom is in contact with the ground and the seat is used to place the user's buttocks on it. The support part is connected between the bottom part and the seat part, and is used to support the seat part. There are few types of chairs made of bamboo. However, they are all knitted, and the bamboo chair after molding is poor in elasticity, and uncomfortable feeling is likely to occur when sitting for a long time.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a bamboo elastic chair that conforms to human body engineering and has excellent elasticity, so that it does not get tired even when sitting for a long time.

The bamboo elastic chair according to the present invention comprises a plurality of long rod-shaped outer bamboo materials and a plurality of long rod-shaped inner bamboo materials. The outer bamboo material and the inner bamboo material have a U shape, the outer periphery size of the inner bamboo material is smaller than the inner periphery size of the outer bamboo material, and both opposite sides of the outer bamboo material and the inner bamboo material in the U shape protrude outwardly. The upper side forming the sides and connecting the both sides forms a concave arc surface that is recessed in the inner direction, and the inner bamboo material and the outer bamboo material are stacked on each other to form a chair unit, and the chair units are arranged in parallel. A plurality of long bar-shaped first reinforcing members and a plurality of long bar-shaped second reinforcing members are provided between the inner bamboo material and the outer bamboo material.

It is the perspective view which showed Example 1 of this invention. It is the top view which showed Example 1 of this invention from the side. It is explanatory drawing which showed the state which the outer side bamboo material of Example 1 of this invention exhibits elasticity. It is the perspective view which showed the bamboo elastic chair which added the backrest of Example 2 of this invention. It is the top view which showed the bamboo elastic chair which provided the four legs of Example 3 of this invention.

Example 1
First, FIG. 1 and FIG. 2 will be referred to. The bamboo elastic chair according to the first embodiment of the present invention is composed of a combination of long stick-shaped bamboo materials, and a plurality of outer bamboo materials 1 bent into a U shape and a plurality of inner bamboo materials 2 bent into a U shape. With. The outer periphery size of the inner bamboo material 2 is smaller than the inner periphery size of the outer bamboo material 1. The opposite sides of the U-shaped outer bamboo material 1 and the inner bamboo material 2 facing each other form an arc-shaped side projecting outward, and the upper side connected to both sides forms a concave arc surface 1A recessed in the inner direction, A chair unit is formed by overlapping the inner bamboo material 2 and the outer bamboo material 1 with each other. A plurality of chair units are arranged in parallel, and a plurality of long bar-shaped first reinforcing members 4A and a plurality of long bar-shaped second reinforcing members 4B are formed between the inner bamboo material 2 and the outer bamboo material 1 of each chair unit. Then, the sandwiched space 3 is formed between the outer bamboo material 1 and the inner bamboo material 2 of the chair unit by the first reinforcing member 4A and the second reinforcing member 4B. Among them, the first reinforcing member 4A is provided at a location near the upper side of the inner bamboo material 2 and the outer bamboo material 1 and not exceeding the bent position, and is bonded using an adhesive, or The first reinforcing member 4 </ b> A is fixed to the outer bamboo material 1 and the inner bamboo material 2 using a fixing member such as a tenon or a nail. The second reinforcing member 4B is provided at the lower end position of the side of the inner bamboo material 2 and the outer bamboo material 1, and is bonded with an adhesive or using a fixing member such as a tenon or a nail, and the second reinforcing member 4B is an outer bamboo material. 1 and the inner bamboo 2 are fixed. As a result, the inner bamboo material 2 and the outer bamboo material 1 are separated by the first reinforcing member 4A and the second reinforcing member 4B, and a sandwiched space 3 having the same width is formed. Since the first reinforcing member 4A of the present invention is provided at a location that does not exceed the bent position above the chair unit, the sandwiched space 3 between the two concave arc surfaces 1A of the outer bamboo material 1 and the inner bamboo material 2, The outer bamboo 1 is provided with a vertical elastic space (shown in FIG. 3).

In the bamboo elastic chair structure described above, since the concave arc surface 1A of the outer bamboo material 1 corresponds to the degree of arc of the human buttock, when the user sits on the concave arc surface 1A, it is possible to obtain a perfect fit effect. In addition, since the upper and lower elastic spaces are provided by the sandwich space 3 between the concave arc surface 1A of the outer bamboo material 1 and the concave arc surface of the inner bamboo material 2, the outer bamboo material 1 is elasticized after receiving the weight of the human body. You can get a soft feel when you descend and sit down. Moreover, since the both sides of the support leg of the chair are arc-shaped sides protruding outward, the cushioning action of the chair is also provided. Further, when the chair suddenly receives an impact force from top to bottom, the sides of the concave arc surface 1 </ b> A have elastic buffering spaces, and both sides of the chair have the effect of elastically expanding outward, thus vibrating. This can improve the comfort of the elastic chair.

(Example 2)
FIG. 4 is a perspective view showing a second embodiment of the bamboo elastic chair of the present invention. In the second embodiment, in addition to the above-described structure of the U-shaped elastic chair, a backrest 5 is provided on one side of the chair. The backrest 5 is formed by arranging a plurality of vertical bamboo members 51 in parallel, and further combining a horizontal bamboo material 52 at the upper end of the vertical bamboo members 51. In the second embodiment, in addition to the advantages of the first embodiment, the chair itself allows the user sitting on the chair to lean his back against the backrest 5, and the superior elasticity of the bamboo material itself makes the back feel comfortable. There is an effect that can be made.

(Example 3)
FIG. 5 is a perspective view showing a third embodiment of the bamboo elastic chair of the present invention. In the third embodiment, in addition to the structure of the U-shaped elastic chair of the first embodiment, an air-permeable space 6 whose edges are arcuate is provided on both opposite sides of the chair. A long rod-shaped third reinforcing member 4C corresponding to the shape of the edge of the air-permeable space 6 is formed between the outer bamboo material and the inner bamboo material of the two air-permeable space 6 edges, and the two third reinforcing members 4C are formed. One end extends to the back of the chair and becomes two back support legs B of the chair. The pair of outer bamboo material and inner bamboo material on both front sides of the chair form two front support legs A of the chair. Thus, a chair having four legs is formed. The third reinforcing member 4 </ b> C extends upward to form an arc-shaped backrest 5 </ b> A, and the user's back when sitting can obtain a comfortable feel.
