Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a chair, seat, cushion, backrest, pillow, etc. that utilizes the elasticity of wood or bamboo.

[Conventional technology]

In the past, benches, chairs, pillows, etc. made of wood or bamboo existed, but they were all made from a single, fairly thick board and were hard and inelastic.
Of course, it was unthinkable to make cushions and backrests out of wood or bamboo.

[Problem that the invention attempts to solve]

In view of the current situation, the present invention is to create new comfortable chairs, benches, backrests, cushions, pillows, bags, etc. that are made of wood or bamboo but have elasticity.

[Means to solve the problem]

In the present invention, as a result of various experimental studies, wood or bamboo is made with a thickness of about 3 mm to 8 mm, formed into a long rectangular parallelepiped, horizontally elongated holes are bored on the left and right sides of the rectangular parallelepiped, and this is made into a unit plate. It was found that when used in layers, they flexed better, unlike a single thick board. A pair of separate left and right support stands are provided with long through holes that slope downward toward the center between the support stands. A structure was adopted in which several pillars were placed in parallel one after the other, and a support column was inserted and fixed from the upper surface of the support table through the horizontally elongated hole of the unit plate to reach the support table.

Further, if necessary, a holding frame is provided below the through hole of the support base to restrict the downward limit of the central portion of the unit plate.

[Effect]

Although the structure of the present application is as described above, it can be adapted to various uses by changing the thickness and width of the unit plates and the number of stacked plates depending on the use.

When in use, when a person sits down and puts weight on the center of the unit plate, the horizontally long holes in the thin unit plate slide toward the center through the inclined through-holes in the support base, and the thin unit plate is closed. The overlap of the unit plates helps in bending, making it possible to create a chair with comfortable elasticity instead of the conventional stiffness. will not break.

In addition, when the through-hole of the support base is at a low position, the sliding of the unit plate is controlled only by the support, and when the through-hole is at a high position, a holding frame is installed at the bottom of the through-hole to limit the downward movement of the unit plate. to prevent the unit plate from breaking. When the weight is no longer applied, the unit plate returns to its original state due to its restoring force.

〔Example〕

An example will be described with reference to the figures. FIG. 1 shows the structure of a cushion, a chair, or a seat part of a seat. A is a diagram showing the whole, 1 is a unit plate, and 2 is a pair of left and right support stands. Unit plate 1 is approximately 3mm~
It is formed into an elongated rectangular parallelepiped with a thickness of about 8 mm, and horizontally elongated holes 1a are bored at both left and right ends, respectively. The pair of left and right support stands 2 are each formed to have the required length, height, and appropriate width, and the interval is determined by the use of the holding frame 2a.
defined by. The support stand 2 is provided with a longitudinally long through hole 2b that slopes downward toward the center between the support stands 2. This through hole 2b may be a horizontal hole instead of an inclined hole, but when the unit plate 1 shifts to the center, it hits the lower corner of the through hole 2b, producing unnecessary friction noise. Further, in the embodiment, the through holes 2b of the support base 2 are long holes in the front and back, but a plurality of through holes 2b may be arranged in parallel so that the unit plates 1 can be inserted into each unit individually.

The unit plate 1 is inserted into the through hole 2b, and the metal or wooden support 3 is inserted from the upper end of the unit plate 1.
pass through the horizontally long grooves 1a at both ends of the unit plate 1 and are further fitted into the support base 2. Of course, it may also be screwed on.

FIG. 2 shows an embodiment of a chair with a drawer, in which the side panels 2, 2 of the drawer serve as a support base, and the top plate of the drawer serves as a holding frame 2a.

As another embodiment, FIG. 3 shows a cushion, and the support base 1 is provided with through grooves 2b on the top and bottom, left and right sides,
Holding frames 2a are also provided at the four corners of the support base 1, and a reinforcing frame is further provided at the center (see FIG. 3B).

As further examples, FIG. 4 shows a pillow, FIG. 5 shows a basket, and FIG. 6 shows an overall view of a chair.

〔effect〕

As shown above, the present invention provides horizontal grooves on both sides of a thin and long piece of wood or bamboo, overlaps the pieces as appropriate, and inserts the pieces into the inclined through-hole of the support stand that defines the distance between the left and right pairs. However, when a human uses it and force is applied to the center of the unit plate, the unit plate bends, but the horizontally long hole in the unit plate slides through the through hole in the inclined support base, and the elasticity of the unit plate is reduced. more emphasis on
This creates elastic chairs and other products that have not existed until now.
