Description

本発明は、スタッキング椅子に係わり、更に詳しくは上下に多数積み重ねて収納することが可能なスタッキング椅子に関するものである。   The present invention relates to a stacking chair, and more particularly to a stacking chair that can be stacked and stored in a large number in the vertical direction.

従来から金属パイプ製のフレームに座部と背凭れ部を取付けるとともに、上下に積み重ねることができるようにフレームの形状を下方へ広がった形状としたスタッキング椅子は各種提供されている。この種のスタッキング椅子では、フレームの形状は勿論のこと、座部や背凭れ部の厚さが、積み重ねることができる最大の脚数を規定する。   Conventionally, various stacking chairs have been provided in which a seat portion and a backrest portion are attached to a metal pipe frame, and the shape of the frame is expanded downward so that the frame can be stacked up and down. In this type of stacking chair, not only the shape of the frame but also the thickness of the seat and backrest defines the maximum number of legs that can be stacked.

特許文献１には、脚フレームと背フレームと一体的に形成した金属材料製（ステンレス鋼製パイプ、ハイテンションパイプ等）のフレームに、座部と背凭れ部とを着脱可能に取付けた構造のスタッキング椅子が開示されている。具体的には、左右一対の脚フレームの上端間に溶接した座フレームに、座部をネジ止めして取付けるとともに、背フレームに背凭れ部を取付ける。ここで、前記背凭れ部は、合成樹脂製の背凭れ板とクッション材を含む上張り部材とからなり、背凭れ板は表板と裏板から構成され、前記背フレームの両側背凭れ支持杆の内側に固定した支持片に、前方から表板を当てて後方からネジ止めするとともに、裏板を表板に嵌着する構造が開示されている。   Patent Document 1 describes a structure in which a seat portion and a backrest portion are detachably attached to a frame made of a metal material (stainless steel pipe, high tension pipe, etc.) integrally formed with a leg frame and a back frame. A stacking chair is disclosed. Specifically, the seat is screwed and attached to a seat frame welded between the upper ends of the pair of left and right leg frames, and the backrest is attached to the back frame. Here, the backrest portion is composed of a synthetic resin backrest plate and an upper member including a cushion material, and the backrest plate is constituted by a front plate and a back plate, and both side backrest support ridges of the back frame are provided. A structure is disclosed in which a front plate is applied to a support piece fixed to the inside of the front plate and is screwed from the rear, and the back plate is fitted to the front plate.

しかし、前記背凭れ板は、合成樹脂で成形したものであるので、強度を保つために薄くするのにも限界があり、しかも表板と裏板には、布や合成樹脂製のクロス又はレザーなどの張り地を裏面側に巻き込んでタッカーで固定し、特に表板には更にクッション材を介在させているので、その分だけ更に背凭れ部の厚さは厚くなる。そのため、上下に積み重ねることができる椅子の脚数は比較的少なくなると推測される。
特開２０００−１３９号公報（図６） However, since the back plate is made of synthetic resin, there is a limit to reducing the thickness in order to maintain strength, and cloth and synthetic resin cloth or leather are used for the front and back plates. Such a tension is wound around the back side and fixed with a tacker, and in particular, since a cushion material is further interposed on the front plate, the thickness of the backrest portion is further increased accordingly. Therefore, it is estimated that the number of chairs that can be stacked up and down is relatively small.
