[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawer fall prevention device for preventing a slide rail fixed to a furniture main body from falling due to lifting of the drawer.

[0002]

2. Description of the Related Art Conventionally, a slide rail fixed to a furniture body.
In a drawer in which both sides of the drawer are placed so that they cannot move back and forth with respect to the moving rail of the ruler, as a means for preventing the drawer from falling off due to lifting, there is the one described in JP 62-11480. Are known.

In this fall-out preventing means, an elastic member is projected on a moving rail of a slide rail fixed to a furniture main body, and the elastic member is attached to a mounting rail fixed to a side portion of a drawer main body. Was provided with an engaging hole for engaging with.

[0004]

However, in the above-mentioned conventional fall-out preventing means, the slide rail itself has to be processed so as to attach the elastic member, so that the slide rail itself becomes expensive. Therefore, there is a problem that a commercially available inexpensive slide rail cannot be used.

Further, the mounting means for the slide rail of the drawer is limited to a structure in which the mounting rail fixed to the side surface of the drawer main body is mounted on the upper surface of the moving rail of the slide rail. However, this drop-out preventing means lacks versatility and has a problem that the drawer structure is complicated as a whole.

In view of the above problems of the prior art, the present invention aims to provide a drawer dropout prevention device which is inexpensive, versatile and has a simple structure as a whole.

[0007]

In order to achieve the above-mentioned object, the drawer fall-out prevention device of the present invention is arranged such that both sides of the drawer are moved forward and backward with respect to the moving rail of the slide rail fixed to the furniture body. In a drawer that is immovably placed, it is necessary to attach an engaging member provided with an elastic projection piece that can be engaged and disengaged inside the upper surface of the front end opening of the moving rail to both sides of the rear surface of the front plate of the drawer. It has a feature.

The engaging member is preferably arranged so as to abut the inner surface of the furniture body side plate when the drawer is pushed into the furniture body.

[0009]

Operation: The drawer is placed on the moving rail of the slide rail so that it cannot move forward and backward, and the elastic projections of the engaging members attached to both sides of the rear surface of the front plate of the drawer are attached to the front end of the moving rail. It engages with the inside of the upper surface of the opening to prevent the drawer from rising and prevent the drawer from falling off.

As a result, it is not necessary to process the slide rail itself, and various commercially available slide rails can be used, so that the drawer fall-out preventing device can be manufactured at low cost, and moreover, it is general-purpose. A highly productive product can be obtained (Claim 1).

Further, when the engaging member is arranged so as to contact the inner surface of the side plate of the furniture main body when the drawer is pushed into the furniture main body, the engaging member also has the function of preventing lateral shake of the drawer. As a result, the drawer structure is simplified as a whole (Claim 2).

In FIG. 2, as an example of the inside of the furniture body (1) and a drawer, the drawer (2) at the bottom of the furniture body (1)
About the details. The drawer (2) includes a box-shaped drawer body (3), a front plate (4) attached to the front surface of the drawer body (3), and a mount attached to both outer sides of the drawer body (3). It is composed of a mounting rail (5).

The mounting rail (5) is composed of a band-shaped metal plate which is usually commercially available, and the bent pieces are provided at appropriate positions in the front and rear.
(6) is formed, and an inner rail (9) described later is formed on the bent piece (6).
An engaging hole (7) for engaging with the locking piece (10) is provided.

(8) shows an outer rail, (9) shows an inner rail, and the outer rail (8) is a furniture body side fixed to the inner surface of the side plate (10) of the furniture body (1). It is attached to a rail (not shown) so as to be movable back and forth.

Here, the outer rail (8) and the inner rail
(9) The furniture main body side rail corresponds to the slide rail of the present invention, and the inner rail (9) corresponds to the moving rail of the present invention. Further, the inner rail (9) is inserted into the outer rail (8), and the outer rail (8) and the inner rail (8) are inserted.
Between the (9), a ball member (not shown) is appropriately provided so that the inner rail (9) can move smoothly inside the outer rail (8).
Is provided.

The outer rail (8) and the inner rail (9) have a substantially C-shaped cross section, and like the mounting rail (5), they are made of commercially available strip metal plates. ing. The outer rail (8) is used for pulling out the drawer (2) from the furniture main body (1) in the front-rear direction, and is not always necessary. The inner rail (9) is directly connected to the furniture main body side. It may be attached to the rail.

On the inner rail (9), at appropriate front and rear positions,
A locking piece (11) that engages with the engaging hole (7) of the mounting rail (5) is formed. Therefore, the engaging hole (7) and the locking piece (1
Due to the engagement with 1), the drawer (2) is placed on the inner rail (9) immovably back and forth.

Engaging members (14) having elastic projections (12) are provided on both sides of the back surface of the front plate (4) of the drawer (2). In this embodiment, the elastic projection (12) is, as shown in FIG.
It is composed of a substantially V-shaped leaf spring having a tip portion (13).

The elastic projection (12) is, as shown in FIG.
Alternatively, the fulcrum portion may be formed of a substantially V-shaped leaf spring having a tip end portion (13) wound in a coil shape. Engagement member (14)
Is a hollow member having an opening (15) on the front surface through which the tip (13) of the elastic projection (12) comes in and out.

As shown in FIG. 3, the distal end portion (13) of the elastic projection piece (12) has the engaging hole (7) of the mounting rail (5) and the locking piece of the inner rail (9). When engaged with (11), it is constantly urged from the opening (15) of the engaging member (14) so as to engage with the inner surface (16) of the front end opening of the inner rail (9). Is protruding.
