[Problems to be solved by the device]

 However, according to the above-described mounting structure, there is no means for fixing the storage device on the upper surface of the shelf plate, and the lateral displacement of the storage device is prevented by the frictional resistance between the shelf plate and the foot of the storage device. However, there is a problem that there is a possibility that the mounted storage equipment may move sideways and fall from the shelf board and be damaged due to vibrations such as an earthquake because the equipment does not have any seismic resistance.

In view of the above problems, it is an object of the present invention to provide a rack seismic resistant storage structure in which a storage device placed on a shelf does not move due to vibration.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, in the seismic resistant storage structure for a rack of the present invention, a storage device mounted on at least one shelf plate constituting a rack and having a foot, and a rack for moving in the front-rear direction. A rear end regulating member that is capable of abutting against the rear end of the storage device and is fixed to the shelf plate, and a foot that is movable in the left-right direction of the rack and that holds the foot of the storage device and is fixed to the shelf plate It is composed of a holding member and a holding member that presses the storage device to the side of the shelf to fix it to the shelf.

[0007]

[Action]

 The rear-end restricting member contacts the rear end of the storage device, and the foot support member holds the foot so that the back-and-forth and left-right movements of the storage device can be restricted. It is possible to suppress the floating of the storage device by pressing it to the shelf board and fixing it to the shelf board.

[0008]

【Example】

 Hereinafter, the gist of the present invention will be described in detail with reference to the embodiments shown in the drawings. 1 is a front view of the rack, FIG. 2 is a side view of FIG. 1, and FIG. 3 is a perspective view of the shelf board of FIG.

As shown in FIG. 1 and FIG. 2, the seismic resistant storage structure of the rack has a frame-shaped frame 1 as in the conventional case, and a front and rear, left and right side walls formed by bending the four edges of a square sheet metal into a frame shape. It is composed of a flat shelf plate 2 on which a storage device 7 indicated by a chain double-dashed line is placed by partitioning the internal space of the frame 1 into upper and lower stages by welding to the front and rear left and right columns 1a of the frame 1. The shelf board 2 is further different in that it has a seismic resistant storage structure including a rear end regulating member 3, a pair of left and right foot supporting members 4 and a pressing member 5 as shown in FIG.

The rear end regulating member 3 is formed by bending a strip-shaped sheet metal having the same length as the width of the shelf plate 2 in the left-right direction into a right angle L shape, and has screwing means 10 at both ends, that is, a mounting hole. With 3a. The rear end restricting member 3 has a mounting screw 6 inserted through a screwing means 10 formed in the left and right edges of the upper surface of the shelf plate 2, that is, a long hole 2c-1 in the front-rear direction with a nut (not shown).

In the case of screwing, the pair of left and right foot support members 4 are fixed in advance, and the rear end regulating member 3 is moved and adjusted in the front-back (depth) direction to be indicated by a two-dot chain line. Abut on the rear end of 7 and screw in the storage device 7 without play in the front-back direction. Thereby, the movement of the storage device 7 in the front-rear direction is restricted.

Next, the foot support members 4 have the same shape by using a pair of left and right feet. The pedestal holding member 4 is formed by bending a strip-shaped metal plate into a right angle L shape, and holding one end of the bent piece in a circular shape in which the pedestals 7a on the front and left sides can be inserted among the pedestals provided at the four corners of the bottom surface of the storage device 7. A hole (through hole) 4a is provided.

Immediately after the holding hole 4a, a Z-shape is formed so that the holding hole 4a can be inserted into a left-right elongated hole 2c-2 formed at the front edge of the upper surface of the shelf plate 2. The Z-shaped bent portion is inserted into the long hole 2c-2 so that the other bent piece is brought into contact with the inner surface of the front side wall 2a of the shelf board 2 so as to follow the back surface of the shelf board 2.

The screwing means 10 formed in this bent piece, that is, a screw hole (not shown) is formed in the front side wall 2a of the shelf 2 in the screwing means 10, that is, a long hole 2c-3 in the left-right direction. Correspond. The left and right foot supporting members 4 are inserted into the holding holes 4a in the front left and right feet 7a of the storage device 7 and further inserted into the long holes 2c-2 on the upper surface of the shelf board 2. After positioning 7 in the approximate center of the shelf plate 2, insert the mounting screw 8 through the long holes 2c-3 on the left and right of the front side wall 2a of the shelf plate 2 and screw it into the screw hole (not shown) of the bent piece on the back side. To do. As a result, the lateral movement of the storage device 7 is restricted via the foot 7a.

Next, the pressing member 5 is a flexible strip-shaped spring plate that presses the storage device 7 from above, and is provided with screwing means 10, that is, an elongated hole 5a at both ends thereof. The long hole 5a has such a length that the storage device 7 can be adjusted to various heights.

In the holding member 5, the mounting screw 9 is passed through the long hole 5a in a state where the storage device 7 is pressed down from above, and the screwing means 10, that is, the screw hole ( (Not shown). This prevents the storage device 7 from rising due to vibration.

As described above, the front-rear direction of the storage device is regulated by the rear end regulation member, the left-right direction is regulated by the foot support member, and the lifting of the storage device is regulated by the pressing member, so that the rack It is possible to prevent the storage devices placed on the shelf from falling from the shelf due to vibration such as an earthquake. Further, the screwing means for the rear end regulating member, the foot supporting member, and the shelf plate of the pressing member are formed as long holes so that they can be adjusted in the regulating direction, so that they can be screwed to accommodate storage devices of various sizes. can do.

[0018]

[Effect of device]

 As described above in detail, according to the present invention, since the storage equipment can be securely fixed to the rack shelf by using the foot of the storage equipment, it contributes to the improvement of earthquake resistance and is extremely useful in practice. Demonstrate.
