Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawer guide device, and more particularly to a drawer guide device capable of pulling out an entire drawer housing from a fixture body such as a cabinet, a desk or a counter.

[0002]

2. Description of the Related Art Conventionally, various types of drawers which are supported by a pair of left and right guide rails so as to be able to be pulled out are provided in a storage portion of a furniture main body such as a cabinet, a desk and a counter. Normally, in consideration of the maximum space efficiency of the drawer accommodating section with respect to the storage section of the main body, the total length of the guide rail and the depth dimension of the drawer accommodating section are set to be substantially the same, and the Designed to reduce space. So, with a low cost simple thing,
As the guide rail, a single-type guide rail comprising a fixed rail attached to the main body side and a movable rail attached to the drawer side is used. In this case, since the stroke is shorter than the entire length of the guide rail, the entire accommodation portion of the drawer from the main body is used. It is impossible to draw out. In other words, the inner part of the drawer receiving portion cannot be pulled out from the main body to the front, and it is very troublesome to put articles in and out of this portion.

[0003] Japanese Patent Publication No. 49-44830 discloses a movable guide that slides on a fixed rail attached to a desk as a device in which the entire storage portion of the drawer can be pulled out from the main body using a single guide rail. Provide a long groove on the rail,
A slider attached to the lower surface of the drawer is slidably fitted in this long groove, and the slider is slid along the long groove of the movable rail and pulled out. A drawer sliding device is disclosed in which the side plate at the rear of the drawer can be drawn forward from the front surface of the desk by pulling the side plate as far as possible.

[0004] However, when a normal single guide rail is used, the movable rail is stable because the movable rail is fixed to both sides of the lower surface of the drawer. Is very unstable, because it merely slides on the fixed rail and the slider mounted on the lower surface of the drawer is slidably fitted in the long groove provided in the movable rail. It is expected that the movable rail oscillates left and right with the sliding operation of, and that the movable rail comes into contact with the fixed rail and the side surface of the drawer, causing damage or generating a metallic sound.

[0005] In the case of a relatively high-cost one, a so-called suspension rail comprising a fixed rail, a movable rail and an intermediate rail is used as the guide rail, and the entire drawer housing can be pulled out from the main body. Those are known.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned situation, the present invention is to solve the problem by a low-cost single unit consisting of a fixed rail attached to a furniture body such as a cabinet and a movable rail attached to a drawer side. Despite the use of the guide rail, the drawer can be pulled out from the main body while setting the maximum depth of the drawer with respect to the main body and ensuring high space efficiency of the drawer storage section. It is in providing a guidance device.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention uses a simple guide rail consisting of a fixed rail attached to the fixture main body and a movable rail attached to the drawer side, which is pulled out to the main body. A drawer guide device that is supported so that it can be pulled out front and back, and fixed rails are attached to both sides of the drawer storage space on the main body side, and movable rails slidably mounted on each fixed rail so that it can slide back and forth. Respectively, and a drawer is slidably mounted on the connecting member so that the drawer can be slid forward and backward. A drawer guide device comprising guide means for allowing the drawer to move forward with respect to the connecting member and preventing the rear portion of the drawer from rising. It was.

Here, the connecting member is plate-shaped, the movable rails are fixed to both sides of the board, and the lower surfaces on both sides of the drawer can be slid back and forth on supporting edges rising on both sides of the board. A guide groove extending in the depth direction is cut or opened in the rear part of the substrate as the guide means, and a cross section substantially L is provided on the lower surface of the rear part of the drawer.
