Description

[Detailed Description of the Invention] The present invention relates to an overturn prevention device for furniture, particularly horizontal filing cabinets that have a wider width than depth.

This type of cabinet may tip forward or fall over when a drawer containing a heavy object is pulled out. In the present invention, these types of cabinets are placed side by side on an underframe and their lower ends are locked to the underframe, thereby preventing the danger of them falling over.

Next, the details will be explained with reference to the illustrated embodiment. 1 is a horizontally mounted filing cabinet body;
2 is a drawer, 3 is an underframe on which the cabinet body 1 is placed side by side, and the underframe 3 is made up of front and rear and both side frame plates 3a, 3b, 3c, and 3c, each having a substantially inward U-shaped cross section; front and rear frame plates 3a, 3b
A reinforcing plate 4 having a substantially U-shaped cross section is installed between them, and height adjustment bolts 5, 5, . . . are provided at appropriate locations on the reinforcing plate 4. Further, the inner edge of the upper plate portion 3c of the side frame plate 3c is further bent upward to provide a stopper piece 6 for positioning when the cabinet main body 1 is placed. A similar positioning stopper piece 7 is also provided in the middle part of 3b. As shown in FIGS. 3 and 4, on this underframe side frame plate 3c, a locking plate 8 having a hook 8a facing outward at its upper end is pivotally supported 10 via a mounting plate 9. is urged outward by a spring 11 provided between the lower end of the locking plate 8 and the mounting plate 9, and is locked to the stopper piece 6.

When placing the cabinet body 1 on the underframe 3 by gradually lowering it from above and placing the U-shaped bent portion 1' at the lower end of the body 1 along the stopper piece 6 of the side frame plate 3c, first The U-shaped bent portion 1' engages with the inclined upper surface 8a' of the hook 8a to rotate the locking plate 8 inward against the spring 11, and the U-shaped bent portion 1' engages with the inclined upper surface 8a' of the hook 8a. 3, the hook 8a also disengages and returns to its original position by the spring 11, automatically locking the bent edge 1'' of the U-shaped bent portion 1' of the main body 1. do.
Further, the main body 1 is positioned by stopper pieces 6 and 7. Although not shown, the other cabinet body to be juxtaposed can also be secured onto the underframe 3 very easily in the same manner.

When removing the main body 1 from the underframe 3, remove the side frame plate 3c.
Insert a push rod 13 (Fig. 3) such as a screwdriver into the through hole 12 provided on the side of the
The main body 1 can be easily removed from the underframe 3 by rotating inward against the force and releasing the hook 8a.

Therefore, one of the main bodies 1 placed side by side on the underframe 3,
For example, even if the main body 1 does not tilt forward when a drawer 2 containing a heavy item is pulled out, the main body 1 is connected to the other cabinet main body via the underframe 3, so the weight of the other cabinet main body will cause the drawer 2 to tilt forward. Since the overturn prevention device of the present invention has the above-described structure, it is possible to prevent the furniture main body 1 from tilting or overturning. It can be locked to the frame 3, and the fall of the furniture main body 1 can be reliably prevented by the other furniture main bodies 1, 1, etc. placed in parallel on the underframe 3 in the same way. The push rod 13 is inserted through the through hole 12 provided on the side of the frame plate 3.
By inserting and pressing the hook 8a, the hook 8a can be released and the furniture body 1 can be removed from the underframe 3 very easily, which has practical effects such as being extremely convenient for changing the arrangement of the furniture body, etc. have.

When three or more furniture bodies 1 are placed side by side on the underframe 3, the locking plates 8 are attached to the frame plates 3a before and after the middle part,
3b etc., and the intermediate furniture main body 1 may be locked thereto.

Claims (1)

[Scope of utility model registration request] A locking plate 8 having a hook 8a having an inclined upper surface 8a' at the upper end is rotatably supported on a frame plate at a position corresponding to each body of the underframe 3 on which a plurality of furniture bodies 1 are to be arranged side by side. The locking plate 8 is springed with a spring 11 to lock the upward stopper piece formed on the inner edge of the frame plate, and the bent part 1' of the lower end of the furniture main body 1 is placed on the underframe 3 by the stopper piece. By placing the bent portion 1' along the frame plate, the bent portion 1' is locked to the hook 8a, and the locking plate 8 is pressed against the side surface of the frame plate to lock the hook 8a. A fall prevention device for furniture, which is provided with a through hole 12 for a push rod 13 to be released.
