Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suitable mounting structure for an optional member applied to a temporary stand used in various events and the like.

[0002]

2. Description of the Related Art At event venues such as golf tournaments and outdoor concerts, temporary stands that are assembled and dismantled on the spot are used. In such a temporary stand, it may be necessary to provide an optional member such as an armrest, a cup holder, or a memo table, depending on the characteristics of the event, the number of required seats, and the like. Conventionally, as such an optional member, a member in which the optional member is formed integrally with the chair, and a member in which the optional member is screwed to the chair are known.

[0003]

However, when the optional member is integrally formed with the chair, it becomes large as a whole, and in a temporary stand in which installation, removal, transportation, storage, etc., must be repeatedly performed, such a member is not suitable. Handling is extremely inconvenient. Further, since it is necessary to prepare in advance a chair integrally provided with optional members corresponding to the characteristics of the event and the like, there is a problem that the selection range of the optional members becomes narrow. Conversely, if a chair provided with other types of optional members is prepared, there is a problem that the cost increases accordingly. On the other hand, in the case where the optional member is screwed to the chair, it is necessary to screw a large number of places or the mounting position of the optional member is limited, so that it is difficult to quickly respond as needed. Further, when the optional member is not attached to the chair, there is a problem that a screw hole or the like is exposed on the surface of the chair and the appearance is impaired. That is, none of the conventional ones allows quick and appropriate attachment and detachment of optional members according to the purpose.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention makes effective use of a leg structure to which a chair is to be attached in a temporary stand, and easily attaches and detaches the object as required.
