In a disassembled state of the chair, the seat surface member forms a first flat member, the back surface member forms a second flat member, and the first side face leg member combined with the second side face member forms a third flat plate, with storing made possible by laminating the first, second, and third flat members. Also, the seat surface member is fastened by rotating the same for the seat surface receiving part of the first side face leg member and for the second side face leg member. The back surface member is fastened by rotating the same for the back surface receiving part of the first side face leg member and for the second side face leg member.SELECTED DRAWING: Figure 2

Description

本発明は、平板状のパーツ（部材）から組み立てられる平板組立椅子に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat plate assembly chair assembled from flat plate parts (members).

従来より、携帯性や収納面を考慮した組立式の椅子がある。例えば、特許文献１に記載の組立椅子は、金属フレームや金具を使用することなく、木製の４枚の平板をスライド式に組合せてなる組立椅子が提案されていた。 Conventionally, there have been collapsible chairs in consideration of portability and storage space. For example, Patent Literature 1 proposes an assembly chair in which four wooden flat plates are combined in a sliding manner without using a metal frame or metal fittings.

特開２００２－１７４６３号公報JP-A-2002-17463

しかし、特許文献１に記載の組立椅子は、各パーツが１枚のプレートを構成し、収納時に４枚の平板（プレート）を重ねるもので、収納時の厚さが厚くなってしまうという課題があった。また、スライドのみにより組み立てられているため、椅子の状態で移動させようとするとき部材が簡単に外れてしまうという課題があった。 However, in the assembly chair described in Patent Document 1, each part constitutes one plate, and four flat plates (plates) are stacked when stored, so there is a problem that the thickness of the assembled chair increases when stored. there were. In addition, since it is assembled only by sliding, there is a problem that the members can easily come off when trying to move it in the state of a chair.

上述のような課題を解決すべく本発明の発明者は鋭意検討したところ、本発明に係る平板組立椅子は以下の構成を有する。 As a result of intensive studies by the inventors of the present invention in order to solve the above problems, the flat plate assembly chair according to the present invention has the following configuration.

（１）本発明に係る平板組立椅子は、平板状の部材からなる平板組立椅子であって、平板状の第１の側面脚部材と、平板状の第２の側面脚部材と、平板状の座面部材と、平板状の背面部材とを含み、椅子に組み立てられた状態で、前記第１の側面脚部材と前記第２の側脚部材とは椅子の脚となり、前記座面部材は、椅子の座面となり、前記背面部材は、椅子の背もたれとなり、椅子を分解した状態で、前記座面部材が第１の平面部材を形成し、前記背面部材が第２の平面部材を形成し、第１の側面脚部材と第２の側面脚部材とを組み合わせて第３の平板を形成し、第１の平面部材と第２の平面部材と第３の平面部材とを積層して収納できる。これにより、平板組立椅子は、収納時に３枚の平板（プレート）を重ねるもので、収納時の厚さを薄くできる。 (1) A flat-plate assembly chair according to the present invention is a flat-plate assembly chair made up of flat-plate-like members, comprising a flat-plate-like first side leg member, a flat-plate-like second side leg member, and a flat-plate-like a seat surface member and a flat plate-like back surface member, and when the chair is assembled, the first side leg member and the second side leg member serve as legs of the chair, and the seat surface member comprises: forming a seat surface of a chair, the back member forming a backrest of the chair, the seat member forming a first planar member and the back member forming a second planar member when the chair is disassembled; A third flat plate is formed by combining the first side leg member and the second side leg member, and the first plane member, the second plane member and the third plane member can be stacked and stored. As a result, the flat plate assembly chair is made by stacking three flat plates (plates) when stored, so that the thickness when stored can be reduced.

（２）本発明に係る他の平板組立椅子は、平板状の部材からなる平板組立椅子であって、第１の側面脚部材と、第２の側面脚部材と、座面部材と、背面部材とを含み、前記第１の側面脚部材および第２の側面脚部材とは、それぞれ、前記座面部材の一部を受け入れる座面受部と、前記背面部材の一部を受け入れる背面受部とを有し、前記座面部材は前記第１の側面脚部材の前記座面受部および前記第２の側面脚部材の前記座面受部に受け入れられたのち、前記座面部材を回転させることにより固定され、前記背面部材は前記第１の側面脚部材の前記背面受部および前記第２の側面脚部材の前記背面受部に受け入れられたのち、前記背面部材を回転させることにより固定される。これにより、椅子が回転により固定されるため、椅子の状態で移動させようとするときも部材が簡単に外れてしまうことを防止できる。 (2) Another flat assembly chair according to the present invention is a flat assembly chair made up of flat plate-like members, comprising a first side leg member, a second side leg member, a seat member, and a back member. and wherein the first side leg member and the second side leg member are respectively a seat surface receiving portion that receives a portion of the seat surface member and a back surface receiving portion that receives a portion of the back surface member. wherein the seat surface member is received in the seat surface receiving portion of the first side leg member and the seat surface receiving portion of the second side leg member, and then the seat surface member is rotated After the back member is received in the back receiving portion of the first side leg member and the back receiving portion of the second side leg member, the back member is fixed by rotating the back member. . As a result, since the chair is fixed by rotation, it is possible to prevent the member from easily coming off even when the chair is moved.

本発明によれば、収納時の厚さが薄い組立式の椅子、または椅子の状態で移動させようとするとき部材が簡単に外れてしまわない組立式の椅子を提供できる。 According to the present invention, it is possible to provide an assembly type chair which is thin when stored, or an assembly type chair whose members do not easily come off when it is moved in the state of the chair.
