DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fall prevention device for preventing furniture such as a closet and a bookshelf from falling due to an earthquake or the like.

[0002]

2. Description of the Related Art In general, a fall prevention device of this type has mounting members disposed at both ends, one of which is fixed to a wall or a pillar, and the other of which is fixed to furniture. By doing so, the furniture is prevented from falling over.

By the way, a pair of mounting members cannot always be mounted in a fixed positional relationship, and it is necessary to change their positions in the horizontal direction or the vertical direction depending on the installation position of the furniture. For example, when the pillar and the furniture are displaced in the horizontal direction, it is necessary to displace the pair of mounting members in the horizontal direction accordingly.

[0004] Accordingly, in Japanese Utility Model Publication No. 3-47548, a plurality of members are arranged between a pair of mounting members.
By connecting each member and each member and the mounting member so as to be rotatable about different axes, the horizontal and vertical positions of the pair of mounting members can be appropriately changed. Further, in the overturn prevention device described in Japanese Utility Model Publication No. Sho 60-17146, the position of the pair of mounting members can be changed in the horizontal direction and the vertical direction by connecting the pair of mounting members with a chain.

[0005]

In the former publication, each member including the mounting member is irremovably connected to each other, which is inconvenient for transportation and storage. On the other hand, in the case of the latter publication, the attachment member and the chain are connected by an openable / closable connection tool, and the chain is detachable from the attachment member. Therefore, it is convenient for transportation and storage. However, since the connecting tool has an opening / closing function and its structure is complicated, there is a problem that the strength is low, and as a result, the strength of the entire fall prevention device is reduced.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has a pair of mounting members having an insertion hole at a central portion, and a substantially semicircular curved portion at a central portion. A pair of connecting members having a curved portion penetrating the insertion hole so as to be able to be inserted and removed, and a connection hole through which the connecting member is inserted so as to be able to be inserted and removed at both ends in the longitudinal direction; A removable intermediate member, and in a state where the curved portion of the connecting member penetrates the insertion hole of the mounting member, both ends of the connecting member insert the curved portion into the mounting member with respect to the insertion hole.
The connecting member is detachably connected in a detaching direction, and the curved portion of the connecting member is inserted into the connecting hole of the intermediate member so as to be rotatable and relatively movable in the extending direction of the curved portion. In this case, it is desirable that both ends of the connecting member be rotatably connected to the mounting member about an axis extending in a direction connecting the both ends, for a reason described later. Preferably, the connecting hole is formed larger than the curved portion of the connecting member so that the intermediate member can rotate about the longitudinal axis of the connecting member in a range of approximately 45 ° with respect to the connecting member. Furthermore, it is desirable that an operation hole penetrating in the same direction as the connection hole is formed in the intermediate member at a central portion near the connection hole.

[0007]

According to the first aspect of the present invention, one of the mounting members is fixed to a pillar or a wall. The other mounting member is fixed to furniture such as a closet. Thus, the furniture can be connected to a wall or the like to prevent the furniture from falling. After releasing the engagement between the one connecting member and the mounting member, the one connecting member is removed from the connecting hole of the intermediate member. Thereafter, the intermediate member is pulled out from one of the mounting portions. Thereby, one attachment member, one connection member, and the intermediate member can be disassembled. Similarly, the other mounting member, the other connecting member, and the intermediate member can be disassembled. According to the second aspect of the present invention, by rotating the connecting member, the end of the connecting member and the distal end of the curved portion are aligned in the direction in which the force acts. In the invention according to claim 3, by rotating one connecting member by 45 ° in one direction and rotating the other connecting member by 45 ° in the other direction with respect to the intermediate member, the orientation of the pair of mounting members can be changed. Various changes can be made from the same direction to the orthogonal direction. In the invention according to claim 4, when the mounting member is fixed with a bolt or the like, even if the bolt is covered by the intermediate member, the driver can be inserted from the operation hole and the bolt can be tightened.
