Abstract

PURPOSE: To eliminate the requirement of a troublesome work such as screw setting, maintain the appearance of a chair without any deterioration, and allow chairs to be joined to each other via a simple work, under an application to a foldable chair or the like having no link hardware. CONSTITUTION: Chairs 100 with front frames 1 made of a pipe are laterally joined to each other at adjacent positions. For this purpose, a set of coupling members 8 and 9 is provided at the corresponding positions of each front frame 1 of the adjacent chairs 100, so as to be detachable via elastic deformation. In addition, engagement recesses 83 and 93 are formed on the members 8 and 9 for preventing the turning motion thereof via engagement with the stays 10 of the chairs 100. Also, engagement sections 84 and 94 are formed on the members 8 and 9 to prevent the motion of the chairs 100 in a parting direction via detachable engagement with each other.

By the way, recently, for the purpose of reducing the number of parts and the number of manufacturing steps, the use of such a link fitting is stopped, and the front frame and the rear frame are moved to the open position by other means. A chair with a fixed structure has been considered. However, when adopting such a structure,
The art of connecting chairs will be lost, and it will be indispensable to apply a new connection structure between chairs instead of the conventional one.

In such a case, as shown in FIG.
It is conceivable to attach a pair of connecting fittings g and h that detachably engage with each other to the outer side surface of each frame f using screws i. In addition, the work of forming the screw holes j in the frame f becomes indispensable, and a heavy burden is imposed on the user. Moreover,
If the connection fittings g and h become unnecessary and are removed, the screw hole j opens in an unsightly state on the outer side surface of the frame f, so that the appearance of the chair is impaired.

The connecting member used in the present invention is elastically attached / detached to / from the frame. The connecting member is attached to the frame by applying a slight operation force, and is held in an appropriate connecting posture by the rotation preventing portion. The frames are connected to each other via the engaging portions, and the chairs are connected to each other. Also, by performing the reverse operation, it is possible to easily remove the frame. As described above, as long as the chair has only the frame, the link metal fitting is unnecessary and other structures are not particularly required, so that the application range is wide. In addition, since the work only needs to be performed in and out of the work, the workability is extremely high, and a complicated work for opening a screw hole or the like becomes unnecessary. Moreover, since no screw holes or the like are formed in the frame, even if the connecting member is removed, unsightly holes do not open, and the appearance of the chair can be effectively improved.

Then, the connecting members 8 and 9 are relatively moved in the directions shown by the arrows in FIGS. 11 and 12, and the tongue pieces 84a and 94a of the connecting members 8 and 9 are respectively connected to the connecting members 9 and 8 of the mating piece.
By inserting into the openings 94b, 84b, the connecting members 8, 9 are engaged with each other at the position where the ridges 84c, 94c are over each other, and the behavior that the chairs 100 are separated from each other in the lateral direction is effectively prevented. Like that.

With such a connecting structure, the connecting members 8 and 9 can be elastically attached to and detached from the front frame 1 by applying only a slight operating force, and are not rotated by the engaging recesses 83 and 93. It is possible to maintain the proper connection posture. In addition, if the reverse operation is performed, it is possible to easily remove the front frame 1. As described above, this connection structure can realize the connection without using the link fitting as long as the chair 100 has the front frame 1 or a similar frame, and requires a special structure. Therefore, the present invention can be applied not only to the illustrated chair 100 but also to other chairs over a wide range. In addition, since only the work of attachment and detachment is required, the workability is extremely high, and the work is much simpler than the mounting structure for opening a screw hole or the like. In addition, since it is not necessary to drill a screw hole or the like in the front frame 1, even if the connecting members 8, 9 are removed, an unsightly hole does not open in the front frame 1,
It is possible to effectively improve the appearance of the chair when used alone.

In particular, in the present embodiment, the engaging recesses 83 and 93 as the detent portions are engaged with the support shaft 10 for pivotally connecting the front frame 1 and the seat 3, so that the detent is prevented. It is not necessary to form a scaffold especially for the chair, so that the number of parts can be reduced and the structure can be simplified.

The specific configuration of each part is not limited to the illustrated embodiment. For example, the specific shape of the engaging portion provided on the connecting member may be any known structure as long as it is engaged and disengaged by utilizing elasticity. In the above-described embodiment, the connecting member is mounted on the front frame. However, the connecting member can be mounted on the pivotal connection between the rear frame and the seat if there is sufficient space. Other configurations can be variously modified without departing from the spirit of the present invention.

Since the present invention has the connecting structure as described above, in the case of a chair having a frame, the connecting members can be detachably attached by elasticity to complete the connection between the chairs. . For this reason, even when the necessity or non-necessity of connection arises afterwards, the work of mounting or removing the member can be performed extremely easily, and the workability can be improved. Moreover, since no screws or the like are used, there are no problems such as making holes in the frame and opening unsightly holes in the frame, which simplifies the above work and effectively improves the appearance of the chair. It will be possible. Such an effect can be further enhanced especially by using the detent portion as the engagement recess described, or by making the connecting member slidable along the longitudinal direction of the frame.
