Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a plurality of panels.

[0002]

2. Description of the Related Art Conventionally, for example, a panel used for partitioning a booth such as an exhibition hall has a plurality of side frame members forming left and right side end surfaces of the panel and a plurality of side frame members connecting the side frame members. There are those in which a structural frame body is formed by the horizontal frame member and the panel elements are packed on the front and back surfaces of this structural frame body, and those in which the panel elements are attached to the front and back surfaces of the internal core to form an integrated structure. To do. Further, in this type of panel, it is customary to attach a plurality of panels in the adjoining direction and use them as movable partitions.A nut member is provided on a side frame member of one panel and a bolt is attached from the other side frame member. By inserting a member and engaging with the nut member, adjacent panels can be connected to form a wall surface of a desired size. Further, by previously providing the nut member on either the left or right side frame member of the panel by welding or the like, it is possible to eliminate the trouble of manually holding the nut member at the mounting location, and to lose the nut member. It is also considered that the two panels can be easily connected by preventing the above.

[0003]

However, as described above, when the nut members are attached only to one of the left and right side frame members of the panel, the horizontal direction of the panels should be taken into consideration when connecting the panels. Therefore, it becomes necessary to connect them. That is, for example, if the side parts that are not provided with a nut member on both panels that are adjacent to each other for connection are adjacent to each other, they cannot be connected. The direction in which the members are attached must be determined, and one must be adjacent to the other with the nut member facing and the other without the nut member.

Therefore, the present invention has been made in view of the above-mentioned problems, and even in a movable partition in which a nut member is previously attached to enable easy connection, the connection can be made quickly without worrying about the directionality of the panel. The purpose is to do so.

[0005]

SUMMARY OF THE INVENTION In view of the above problems, according to the present invention, a nut member is attached to both ends of a panel in advance, and a retracting portion that does not engage with the nut member is provided at the base end of the bolt member. Also, by retracting one of the nut members along with the insertion of the bolt member, the bolt member is retracted from the engagement with the nut member provided on the one panel, and engaged with the nut member of the adjacent panel. It is configured to be connected. Accordingly, even in a panel structure in which a nut member is provided in advance and can be easily connected, it is possible to easily connect the panel structure without the need to consider the directionality of the panel.

Further, by rotating the nut member in the bolt insertion direction and retracting it, the nut member can be retracted simply and reliably by only inserting the bolt.
