In the first embodiment, two diaphragm plates 63 are attached, but the number of diaphragm plates 63 may be one or three or more.

When suspending the cabinet 50 from the ceiling 100, it is common to use a wire. However, since the suspended cabinet 50 constantly sways, it is necessary to stretch the wire diagonally in order to suppress the sway. In this case, since it is necessary to secure a space for extending the wire diagonally, the hanging position of the cabinet 50 is limited to a position where the space for extending the wire diagonally can be secured.

On the other hand, when the cabinet 50 is suspended from the ceiling 100 via the displacement restraint member 60 as in the first embodiment, the lateral displacement of the cabinet 50 is constrained by the displacement restraint member 60, so that the suspension member 10 Can be hung at any position as long as it is placed. That is, by regularly arranging the hanging members 10 over the entire surface of the ceiling 100, the cabinet 50 is not restricted in the hanging position.

Further, in a state where the wires are stretched diagonally and the cabinet 50 is hung, when an earthquake occurs, the tension difference between the wires becomes large due to the rolling motion of the earthquake. Therefore, the cabinet 50 sways greatly.

On the other hand, when the cabinet 50 is suspended from the ceiling 100 via the displacement restraint member 60, the displacement restraint member 60 is deformed by the seismic force, and the cabinet 50 tends to be deformed accordingly. However, when a seismic force is generated, each of the side plate 62 and the diaphragm plate 63 is deformed diagonally to cooperate with each other to resist the seismic force. Since flat plates such as the side plate 62 and the diaphragm plate 63 have a large shear rigidity, the displacement restraint member 60 is slightly deformed to the side. Further, with respect to pitching, the anti-vibration rubber 20 cushions the impact and does not cause a large shaking.

In the first embodiment, the plurality of cabinets 50 can be suspended from the suspension member 10 directly or via the displacement restraint member 60. It may also be hung along a wall or in the center of the room. That is, by appropriately selecting the number, size, position, and hanging method of the hanging cabinets 50, it is possible to construct a highly convenient ceiling storage system.

When cleaning a room with the storage furniture installed on the floor, the gap between the storage furniture and the floor may hinder the legs to which the storage furniture is attached, resulting in an area that cannot be cleaned sufficiently. However, when the ceiling storage system is constructed using the cabinet 50 illustrated in the first embodiment, a predetermined gap can be provided between the cabinet 50 and the floor, so that the entire room is left by the cleaning robot. Can be cleaned without.

In addition, since all items that hinder indoor movement when placed directly on the floor, such as magazines, newspapers, documents, and hobby tools, can be stored in the ceiling storage system, children can be accommodated in families with small children. , Can be played safely indoors.

The second embodiment will be described with reference to FIGS. 6 and 7. Since there are many parts having substantially the same configuration in the first embodiment and the second embodiment, different configurations will be mainly described. The same components as those in the first embodiment are designated by the same reference numerals, and different configurations are designated by reference numerals in the 200 series.

The hanging device 201 has a hanging member 210 and a hanger rail 270. As shown in FIG. 6, the five hanger rails 270 are mounted on the ceiling 100 in a state parallel to the wall surface 151 at regular intervals. The number of hanger rails 270, the distance between the hanger rails 270, and the position may be appropriately determined in consideration of the storage furniture to be hung.

As shown in FIG. 7, a roller 271 that rolls in the internal space of the hanger rail 270 is pivotally supported by the hanging rod 213. As a result, the hanging member 210 can move in the direction in which the hanger rail 270 extends.

A male screw 213a is cut on the hanging rod 213. The upper end of the accommodating housing 21 has an adjusting nut 22 that is screwed into the male screw 213a. By rotating the adjusting nut 22, the housing housing 21 moves in the vertical direction while rolling along the male screw 213a. By moving the accommodating housing 21 upward toward the hanger rail 270, the accommodating housing 21 and the hanger rail 270 come into contact with each other in a state where a compressive force is applied. Due to the frictional force generated at this time, the roller 271 is in a braked state, and rolling is restricted. This limits the movement of the hanging member 210. Further, by rotating the adjusting nut 22 to release the contact state between the housing housing 21 and the hanger rail 270, the roller 271 can roll along the hanger rail 270, and the roller 271 moves along the hanger rail 270. can.

This embodiment is an example, and it goes without saying that it can be modified without departing from the technical idea of the present invention. For example, the cabinet 50 may have a structure that can be assembled and disassembled by using the same material as the displacement restraint member.

Since the hanging device of the present invention does not need to place an obstacle that hinders walking on the floor, it is possible to reduce the burden of movement for people with disabilities, for example, people who are forced to move in a wheelchair. In addition, it enables efficient use of space, and in particular, it can be differentiated from other rental apartments by applying it to rental apartments, so it has great industrial applicability.
