Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cabinet, particularly a multi-stage cabinet with fall prevention, in which a vertical multi-section cabinet that is long in the opening direction is provided with a fall prevention device.

Since the drawer of this type of cabinet is long in the frontage direction and short in the depth direction, it has the disadvantage that if multiple stages are pulled out at the same time, the cabinet will tip over forward due to the load of the drawer and its contents.

In view of these points, the present invention improves these drawbacks in multi-stage cabinets.

That is, in the present invention, a vertical rod 3 on which a roller 5 is pivotally supported is provided inside one side wall 2 of the cabinet 1 so as to be slidable up and down, and the side of the drawer 4 accommodated in the cabinet 1 faces the vertical rod 3. An interlocking rod holder 21 having a downwardly sloping portion 8 formed thereon is fixed to the outside of the side plate 9, and the interlocking rod 6 having an upwardly facing locking protrusion 7 at the end thereof is slidably attached to the interlocking rod holder 21. This is a multi-stage cabinet with a fall prevention device, which is movably held and is characterized in that a locking member 10 is provided above the inclined portion 8.

The configuration of the device of the present invention will be explained in detail below with reference to illustrated embodiments.

A suspension 11 is installed horizontally on the outside of the left and right side plates of a drawer 4 housed in the cabinet 1, and a suspension receiver 12 into which the suspension 11 is slidably inserted is installed inside the side wall 2 forming the cabinet 1. and cabinet 1
The drawer 4 is made to be freely slidable inside.

A recess 14 is formed inside one side wall 2 of the cabinet 1, a vertical rod 3 is vertically slidably provided in the recess 14, and a roller 5 is rotatably supported on the vertical rod 3.

The side plate 9 on the side facing the vertical rod 3 of the drawer 4 is formed into a U-shaped cross section above the suspension 11, and the shaft 13 is fixed to the vertical piece at the rear, and the front part is tilted by bending. The interlocking lever holder 21 having the portion 8 formed thereon is fixed.

A stepped portion 16 is formed at the front on the door 15 side upper part of the interlocking rod holder 21 on the side plate 9, and an inward diagonal portion 17 is formed at the rear.
The locking member 10 with the formed shape is fixed. An interlocking rod 6, which will be described later, is placed on the interlocking rod receiver 21, with the shaft 13 inserted into the elongated hole 18, and held by a retaining ring 19 so as to be slidable back and forth. The interlocking rod 6 is formed to have a U-shaped cross section, and a locking protrusion 7 is formed by bending a stepped portion at the rear, and a slide piece 22 is fixed to the upper and lower horizontal pieces of the front portion of the U-shape. A long hole 18 is bored in the vertical piece.

The overturn prevention device for a multi-stage cabinet according to the present invention has the above-described structure, and is formed at the front part of the interlocking lever holder 21 provided on the upper part of the suspension 11 of the drawer 4 which is slidably inserted into the suspension holder 12. The vertical rod 3 is attached to the cabinet 1 so that the roller 5, which is pivotally supported by the vertical rod 3 by the inclined portion 8, is placed on the interlocking rod receiver 21 and the interlocking rod 6.

Therefore, for example, as shown in FIG.
When the drawer 4a is pulled out, the shaft 13 of the interlocking rod 6a comes into contact with the rear end of the elongated hole 18, and is pulled out together with the drawer 4a. At this time, as the interlocking rod support 21 moves forward, the roller 5a pivotally supported by the vertical rod 3 moves from the inclined part 8 formed at the front of the interlocking rod support 21 to the U-shaped cross section of the interlocking rod support 21. When the drawer 4a is moved upward to the upper side and is fully pulled out, it comes into contact with the locking protrusion 7 of the interlocking rod 6a, and the drawer 4a
prevent the movement of

At this time, by moving the drawer 4a forward and lifting the roller 5a, the vertical rod 3 on which the roller 5a is pivotally supported is lifted upward. If an attempt is made to pull out the other drawer 4b in this state, the roller 5b will hit the stepped portion 16 of the locking member 10b and the drawer 4b will not be able to be pulled out because the vertical rod 3 is lifted upward.

At this time, if you want to pull out another drawer 4b, push the drawer 4a that is currently being pulled out into the cabinet 1, and the roller 5a will roll on the interlocking rod 6a and the interlocking rod holder 21, and the drawer 4a will be pushed into the side plate 9 of the drawer 4a. As a result of being brought into contact with the oblique side portion 17 of the fixed locking member 10a and being pushed down on the inclined portion 8, the vertical rod 3 on which the roller 5a is pivotally supported is also pushed down. At this time, the lower roller 5b supported by the vertical rod 3 is also lowered, so the lower drawer 4b
When the roller 5b is pulled out, the locking member 1
You can withdraw without hitting 0h.

As described above, according to the present invention, when the drawer of one stage is pulled out, it is impossible to draw out the other drawers, and the user unconsciously pulls out multiple drawers from the cabinet at the same time. I can't. This prevents extreme shifts in the center of gravity, which causes the cabinet to fall, and there is no worry that the cabinet will fall forward, allowing you to use the drawer to view documents with peace of mind. This will fully achieve the objectives of the period.

In addition, when the drawer is inserted or removed, the roller rolls on the interlocking rod holder with a U-shaped cross section, which not only allows the vertical rod to move up and down smoothly, but also prevents wear of the roller and the interlocking rod holder. A durable cabinet can be provided.
