DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawer structure capable of handling a drawer lightly and a slide plate used for the drawer structure.

[0002]

2. Description of the Related Art For example, drawers are often provided in furniture such as a chest of drawers, storage shelves, desks, tables and the like in order to efficiently store small items in a small space. Usually, in this drawer, a structure is employed in which the drawer body is inserted inward from a drawer frame on the front of furniture and the load of the drawer body is received by a sliding bar or a bottom plate extending inward from the drawer frame.

[0003] By the way, in the past, such furniture was manually manufactured by craftsmen based on their experience and feeling, and could be used for many generations. However, recently, there is a shortage of skilled craftsmen. Therefore, daily furniture other than high-end furniture tends to be mass-produced by machining in factories and the like.

[0004]

However, when furniture is manufactured by machining as described above, each part of the furniture tends to be distorted, deformed, warped, or the like. Particularly, the drawer is pulled by a large force. I couldn't open it without it.

[0005] In view of the above problems, it is an object of the present invention to provide a drawer structure which can be opened and closed lightly even when used for many years.

[0006]

As a result of various studies on the structure of a machined drawer, the present inventor has taken into account distortion, deformation, warpage and the like in the case of machining, and has considered the upper end face of the drawer body and the drawer frame. A gap is formed between the inner surface of the upper end of the
The present invention has been completed, noting that a slide plate can be provided below the drawer main body by using such a gap.

[0007] That is, in the furniture drawer structure according to the present invention, the drawer main body is provided between the upper end surface of the drawer main body and the upper end inner surface of the drawer frame portion from the drawer frame portion provided on the front surface of the furniture. While being inserted with a gap, a sliding bar is provided in the back from both ends of the lower end of the drawer frame, or a bottom plate is provided in the back from the lower end of the drawer frame, and the drawer body is provided by the sliding bar or the bottom plate. In a drawer structure for furniture that receives a load, a sliding plate is fixed to an upper surface of the sliding bar, an upper surface of at least a portion of the bottom plate corresponding to the sliding bar, or a bottom surface on both sides of the drawer main body. Is manufactured using a synthetic resin material to be a flat plate having a width substantially equal to the lateral width of the slide bar and having a length substantially equal to the length of the drawer body, and a bottom surface of the drawer body and the slide bar or the upper surface. Characterized in that the high sliding property between the upper surface of the bottom plate has no possible ensured.

The present invention relates to a chest, storage shelf, desk, table, etc.
Applicable to all furniture with drawers.

The material of the sliding plate is not particularly limited as long as it is a synthetic resin material. The thickness of the slide plate is set to a dimension equal to or smaller than the gap between the upper end edge of the drawer main body and the upper end inner surface of the drawer frame portion, and specifically, is preferably about 0.5 mm to 1.5 mm. The width of the sliding plate is set to be approximately equal to the width of the assumed sliding bar. However, considering the size of the sliding bar of the drawer in ordinary furniture, 10 mm to 20 mm is optimal. Further, it is preferable that the length of the slide plate is substantially equal to the length of the drawer body so that the drawer body can be smoothly drawn over the entire length thereof.

The surface of the sliding plate may be a smooth surface, but it is preferable that at least a part thereof has a small uneven shape in cross section. This allows
This is because the contact with the bottom surface of the drawer main body, the slide bar, or the upper surface of the bottom plate becomes a point contact, the frictional resistance is reduced, and a high sliding property can be secured. In addition, paraffin, wax, or the like is applied to the concave portion having a small uneven shape in cross section, so that higher slipperiness and antistatic property can be secured.

The small irregularities in cross section may be scattered on the surface of the sliding plate, or may be formed on almost the entire surface of the sliding plate. Further, it may be formed in a tint block shape by extending in a meandering manner in the longitudinal direction, or may be formed in a protruding streak shape by extending substantially straight in the longitudinal direction. In particular, when formed in a tint block shape, when unevenness extending in the longitudinal direction is formed on the bottom surface of the drawer main body, the sliding bar, or the upper surface of the bottom plate, it is possible to prevent the tint block from interfering with these unevenness and to guarantee high slipperiness. .

The method for fixing the sliding plate is not particularly limited. For example, the sliding plate can be fixed using a double-sided adhesive tape or an adhesive. Therefore, the back surface of the sliding plate may be a smooth surface, but can be pressed by a woodworking press or the like at the time of manufacturing furniture. Therefore, when at least a part of the back surface of the sliding plate is formed to have a small uneven shape in cross section, the sliding plate is bitten into the top surface of the sliding bar, the top surface of the bottom plate, or the bottom surface of the drawer main body by pressure, so that the fixing strength can be increased.
In addition, in the case of forming a tint block or a streak pattern on the surface of the slide plate, there is a concern that the slide plate may be warped due to the tint block or the streak pattern. , The stress can be balanced and warpage can be prevented.

According to the present invention, the drawer body is inserted from the drawer frame on the front of the furniture with a predetermined gap between the upper end edge and the inner surface of the upper end of the drawer frame. In a drawer structure for furniture in which the load of the drawer body is received by a sliding bar extending from the bottom or a bottom plate extending backward from the drawer frame portion, the upper surface of the sliding bar corresponds to at least the sliding bar of the bottom plate. A sliding plate fixed to a top surface of a portion or a bottom surface on both sides of the drawer main body, having a width substantially equal to a lateral width of the sliding bar using a synthetic resin material, and having a length substantially equal to a length of the drawer main body. Provided is a sliding plate which is manufactured in a flat plate shape and is used for a furniture drawer structure capable of securing a high sliding property between a bottom surface of the drawer main body and an upper surface of the sliding bar or an upper surface of the bottom plate. Door can be.

[0014]

According to the present invention, the sliding plate is provided below the drawer main body by utilizing the gap between the upper end surface of the drawer main body and the upper inner surface of the drawer frame. Thus, even if the furniture is distorted, deformed, warped, or the like, the drawer main body can always be lightly opened and closed.

Further, when the surface of the sliding plate is formed with small irregularities in cross section, the contact area is reduced, and high sliding property can be secured.
The sliding noise of the shoe shoe is hardly generated. In particular, when paraffin, wax, or the like is applied to and left in the small concave portions having the small uneven shape in cross section, the slipperiness can be further improved, and the drawer body can be opened and closed more gently and lightly.

Further, the contact area of the sliding plate can be reduced and the sliding property can be improved. As a result, the generation of static electricity on the sliding plate can be reduced, and there is no sticking of cotton dust and the like.
