JPS6022833Y2 - Device to prevent drawers from tilting forward in filing cabinets - Google Patents

Description

[Detailed description of the invention] The present invention relates to a device for preventing the drawer from tipping forward and preventing the drawer from tipping forward or the cabinet from falling due to this when the drawer is pulled out in a filing cabinet. When the drawer is closed, the wheels attached to the bottom of the drawer are folded into the lower surface of the bottom plate, and when the drawer is pulled out, the wheels are raised so that they can touch the ground.

Next, the details will be explained with reference to the illustrated embodiment. 1 is the cabinet body, 2 is a drawer, and the bottom plate 3 of the lower drawer 2
A rotary rod 4 is provided in the front-rear direction on the lower surface and is supported on a shaft support 4', and a wheel 5 is attached to the bottom plate 3 through a fixture 6 at its front end.
It is installed in a folded state along the lower surface, and an actuating arm 7 is protruded from the rear end of the rotating rod 4, and the position of the front end and rear end of the operating arm 7 is adjusted in the front-rear direction of the bottom plate 1' of the cabinet body 1. is laterally shifted at the bent portion 8' and engaged with the rear portion of a substantially I-shaped guide rail 8 provided opposite to the rotating rod 4, thereby holding the wheel 5 in that position.

When pulling out the drawer 2 from this state, when the wheels 5 are pulled out from the main body 1, the actuating arm 7 rotates at a nearly right angle in the direction of arrow A in FIG. 4, the wheel 5 rotates around the rotary rod 4 and lifts up. At this time, the base 6' of the fixture 6 comes into contact with the seat 9 provided on the drawer bottom plate 3, so that the wheel 5 and the guide rail 8 The operating arm 7 that engages with the front portion of the wheel 5 firmly holds the wheel 5 in a state where it can touch the floor B, thereby reliably preventing the drawer 2 from tilting forward.

When the drawer 2 is closed, the operating arm 7 rotates in the opposite direction at the bent portion 8' of the guide rail 8, so that the wheels 5 are folded along the bottom plate 3 of the drawer 2 and stored in the main body 1 again.

The drawer forward tilt prevention device of the present invention has the above-described structure, and as described above, the wheels 5 are forcibly rotated by the actuating arm 7 at the bent portion 8' of the guide rail 8, so that the drawer is reliably folded or raised. It can be held in the upper position, and while the drawer is closed, the wheels 5 are folded and stored inside the cabinet body 1, so the appearance is no different from that of a normal cabinet, and it does not get in the way when moving the cabinet. This is very convenient, and when the drawer is pulled out, the wheels 5 rise up and are firmly held by the fixture 6 and the operating arm 7 as described above, and the drawer does not tilt forward or backward, so it is possible to prevent the drawer from tilting forward. It can reliably prevent the problem and improve the safety of the cabinet, and has practical effects such as a simple structure and extremely easy manufacture.

This forward tilt prevention device can also be provided in the upper drawer.
