Description

The present invention relates to a chair.

Many conventional chairs with a flexible function of the backrest realize a flexible function by a complicated metal mechanism. In this case, although it becomes the front-back direction, there is nothing corresponding to the back when the body is twisted with respect to the left-right direction.

A chair with a function of bending the backrest has realized a bending function in the front-rear direction by a complicated metal mechanism, there is no bending function in the left-right direction, and it did not fit perfectly with human movement. . The present invention is intended to solve this problem by coming up with a backrest mechanism that extends not only in the front-rear direction but also in the left-right direction.

The present invention uses a member obtained by connecting a plurality of square pillars (bamboo or flexible wood, resin and the like) with cloth on the back portion of the chair. Since the plate material to be formed is bent along the body, the problem is solved because the plate material is movable including twists in the front-rear direction and the left-right direction. Moreover, since sufficient strength cannot be obtained simply by bundling a plurality of plate materials, it is possible to freely move forward, backward, left and right by connecting with a cloth. Further, it was possible to realize sufficient strength by connecting the plate materials with cloth. The chair of the present invention also includes a sofa.

As mentioned above, the chair using the “spinning” by connecting a plurality of square pillars of the present invention (bamboo materials or plastics, plastics and the like) with cloth, Each plate material moves independently, and in addition to the bending function in the front-rear direction, the bending function in the left-right direction works, it fits on the back and can adjust the natural and appropriate backrest and seat angle, A chair that fits more closely with the person's back.

FIG. 3 is a three-sided view of a chair having a backrest that exactly fits the body using “bends” by connecting the cut board members of the present invention with cloth. It is explanatory drawing of the backrest of this chair. The lower part is a cross-sectional view with the upper part wrapped in cloth. This is a member in which a plurality of plate materials made of square pillars are arranged and wrapped with cloth. It is a side view which shows the actual example of this chair. A state of the function to bend in the front-rear direction. It is a top view which shows the actual example of this chair. The state of the function to bend in the left-right direction.

Hereinafter, embodiments will be described with reference to the accompanying drawings. The inside of the cloth bag 6 is in the form of a plurality of vertically long bags, and a plurality of rectangular pillar-shaped (flexible) plate material 5 (bamboo material or flexible wood, resin and the like) is used as the bag. A backrest 1 is formed by being inserted into the shape. By inserting the backrest 1 into the chair body 3, the lower portion of the backrest 1 is fixed and does not move from the seat 2, and the upper portion of the backrest 1 remains bent. By making each flexible plate move independently, not only the front / rear bending function but also the right / left bending function has been realized.

A practical example will be described below with reference to the accompanying drawings. FIG. 3 is a side view showing a practical example of this chair. It is a state of the bending function with respect to the front-rear direction by the bending of the plate material 5 formed of a quadrangular prism inside the backrest 1. FIG. 4 is a top view showing a practical example of this chair. The inside of the cloth bag 6 (shown in FIG. 2) is in the form of a plurality of vertically long bags (bag-like portions) , and a plurality of square plate-like plate materials 5 (bamboo material or flexible wood, resin and the like) The like) is inserted into the bag shape (bag-like portion) to form a backrest 1. By the independent movement of the rectangular plate 5 in the backrest 1, the bending function for the left and right direction works, while it fits on the back, and the natural and appropriate backrest and seat angle can be adjusted. A chair that fits more closely on each person's back.
