Abstract

(57) [Summary] [Purpose] To enable folding chairs to be stacked in a stable state. [Structure] A front leg (2) and a rear leg (3) made of a pipe material are foldably connected. A concave portion (10) is formed on the rear side surface of the rear leg (3) along the outer shape of the front leg (2). When stacked in a folded state, the side surface of the front leg (2) of the upper chair fits along the recessed portion (10) of the rear leg (3) of the lower chair to prevent skidding.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a folding chair, and more particularly to a folding chair that can be stacked in a stable state in a folded state.

[0002]

[Prior art]

 The folding chair, in which the front and rear legs are made of pipe material and connected in a foldable manner, has an arc-shaped surface because the pipe material is composed of round pipes, etc. It is easy to do and it cannot be laminated in a stable state. For this reason, it has been proposed to form the rear leg larger than the front leg so that the front leg fits between the rear legs, or to form the leg material from a rod with a hexagonal cross section. However, the structure is not easily applicable to the conventional folding chair made of pipe material.

[0003]

[Problems to be solved]

 An object of the present invention is to form a front leg and a rear leg of a pipe material, and in a folding chair in which the rear leg is attached to the back side of the front leg so as to be foldable, it is possible to stably stack in a folded state. It is to provide a folding chair.

[0004]

[Means for solving problems]

 According to the present invention, in the folding chair in which the front leg and the rear leg made of the pipe material are foldably connected, when the sheets are stacked in the folded state, the side surfaces of the overlapping legs of one chair become the side surfaces of the other leg. A folding chair having recesses formed on the overlapping surfaces of the legs for fitting is provided to achieve the above object.

[0005]

[Action]

 When the other chairs are placed on the folded chair in line with each other, the lower chair and the upper chair are separated from each other by the recessed portion of the one chair formed on the stacking surface and the side of the leg of the other chair. The faces are mated and the chairs are stably stacked.

[0006]

【Example】

 A description will be given below with examples. In the figure, the front leg (2) and the rear leg (3) of the folding chair (1) are made of a pipe material having a circular cross section, but they can be made of an appropriate elliptical cross section or other appropriate pipe material. , The front end of the rear leg (3) is pivotally attached (4) to the front leg so as to follow the back side of the front leg (2), and the seat portion (6) and the rear leg (5) pivotally attached (5) between the front leg (2). 3) is connected by a link (7), and the whole is foldable as shown in FIG. 2, and a backrest (9) is provided on a back frame (8) connected above the front leg (2). There is. The folding chair can be formed into various known structures other than the one shown in the drawing.

The folding chair is folded and laminated as shown in FIG. 2. When the laminated chairs are stacked, the side surfaces of the legs of one chair which overlap each other fit into the side surfaces of the legs of the other chair. A recess (10) is formed along the overlapping surface. In the embodiment shown in FIG. 3, the rear leg (3) is provided with a recessed portion (10) along the contour of the pipe material forming the front leg (2) from the upper end to the lower end on the back side. The concave portion (10) can be formed in various shapes, but as shown in the figure, it is preferable to form a large curvature of the outer side surface with respect to the inner side surface of the rear leg and to form an outer edge ( Forming 11) so that it is located above the inner edge (12) facilitates stacking and has a great effect of preventing skidding. The inner surface of the rear leg (3) is formed with a fitting portion (13) having substantially the same shape as the recessed portion (10) so that the front leg (2) abuts in a fitted state when folded. However, the fitting portion (13) may not be provided as shown in FIG.

In the above embodiment, the rear leg (3) is formed with the concave portion (10) and the fitting portion (13), but these should be provided on the front leg (2) side instead of the rear leg. Alternatively, as shown in FIG. 5, the rear leg (3) may be formed with a recess (10) and the front leg (2) may be formed with a fitting portion (13) so that they are engaged with each other. Alternatively, contrary to the embodiment shown in FIG. 5, the rear leg (3) may be provided with the fitting portion (13) and the front leg (2) may be provided with the concave portion (10) downward (not shown).

[0009]

[Effect of device]

 The present invention is configured as described above, and the side of the rear leg of one chair and the side of the front leg of the other chair are fitted in the recess when they are stacked directly on top of each other, so that they can be stacked stably without slipping. In addition, since it is only necessary to change the shape of a part of the leg of the conventional chair, the other parts constituting the chair can be conventional and can be obtained economically. is there.
