Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a drawer for office furniture such as a desk or a cabinet, and as a decorative board or the like for decorating the front of a furniture through a back plate integrally provided on the front of the drawer body. The present invention relates to a device for mounting a front plate in a drawer, for stacking and mounting a functioning front plate on a back plate thereof.

[0002]

2. Description of the Related Art Conventionally, a drawer in which a front plate is attached via a back plate fixed to the front of a drawer body,
As seen in Japanese Utility Model Application Laid-Open No. 3-2168, an upper piece is formed at the upper end of the back plate so as to protrude forward so as to abut against the back surface of the front plate of the front plate, and has an upward step. Means has been used in which an inward stepped flange protruding rearward from the upper end of the surface plate is fitted from above into the upward step portion of the piece, so that the front plate is drawn out and overlapped with the main body back plate.

[0003]

However, according to this means, not only the separation of the front plate from above at this part cannot be restricted, but also the inner dimensions of the inward step of the front plate flange and the upper piece of the back plate. The dimensional error between the front and rear widths of the upward step has a disadvantage in that tolerance is extremely small, such that looseness of the fitting dimension causes looseness between the two, and rigidity in the worst case prevents polymerization.

[0004] Further, since the front end of the fitting portion of the upper piece of the back plate is brought into contact with the back surface of the front plate (decorative plate) of the front plate, the steel front plate is frequently pulled out and put in. When the face plate is subjected to a collision load at the time of drawer storage, the tip of the fitting portion of the upper piece of the back plate strongly presses the back surface of the front plate by the collision load, and the distortion swelling to the front side of the front plate forming the decorative plate is reduced. May occur.

[0005] Further, when a wooden front plate is attached to a drawer body having a steel back plate, the thickness of the wooden surface plate for decoration is such that the strength of the wooden front plate can be sufficiently maintained. Since the thickness of the drawer front plate must be increased, the thickness of the drawer front plate differs between the steel front plate and the wooden front plate, and there is also a manufacturing defect that the drawer body cannot be standardized.

SUMMARY OF THE INVENTION The present invention solves the drawbacks of the prior art and ensures that the position of the front plate overlapping the back plate of the drawer body is determined, and that the drawer body can be used in common regardless of the material of the front plate. It is an object of the present invention to provide a standardized front plate mounting device in a drawer.

[0007]

SUMMARY OF THE INVENTION The present invention is directed to a vertical piece which is formed at one of the upper and lower ends of a back plate erected on the front surface of a drawer main body and which is bent at a right angle from a front end of the horizontal piece. Forming a step portion consisting of a single piece portion, forming an appropriate number of engagement holes in left and right key portions of the bent portion, and attaching the vertical piece portion to the step corresponding portion on the back surface of the front plate with the inner surface. The vertical tongue and the horizontal tongue that can be inserted into the engagement hole are formed at key points at the ends of the vertical tongue. After being inserted into the engaging hole of the drawer body, the front plate is rotated to overlap the back plate of the drawer body, and the other end of the front plate is fastened to the drawer body by appropriate means. The above-mentioned problem is solved by attaching the front plate to the drawer body.

[0008]

The horizontal tongue formed on the front plate is inserted into the engagement hole of the back plate to determine the left and right position of the front plate, and the end of the vertical surface of the front plate comes into contact with the bent portion of the back plate. The front plate is rotated about the fulcrum. When the front plate and the back plate are superposed in this way, the upper surface of the horizontal tongue piece contacts the lower surface of the horizontal plate portion of the back plate, and the vertical surface portion of the front plate contacts the vertical piece of the back plate. The end of the front plate is fixed in any of the front, rear, left, right, up, and down directions.

It is provided with a recessed portion (23) cut out and a horizontal groove (24) cut out slightly deeper than the recessed portion (23) on the upper portion.

The horizontal groove (24) has a channel-shaped metal fitting (25) having a horizontal surface on the upper surface having a width corresponding to the depth of the groove (24).
However, it is fitted. The bracket (25) is provided with a vertical piece (26) slightly longer than the rear on the front face plate (22) side.
(26) is fixed to the front plate (22) with an appropriate number of set screws (27).

A horizontal tongue piece (29) similar to the horizontal tongue piece (15) of the front plate (12) is provided on a vertical piece (28) behind the metal fitting (25). The wooden front plate (22) in which the metal fitting (25) is attached to the horizontal groove (24) has the same outer dimensions and the like as the steel front plate (12). The mounting procedure is exactly the same as shown in FIG. In addition,
As shown in FIG. 4, the lower end of the front plate (22) is fixed to the back plate (2) with a set screw (30) from behind the back plate (2).

FIGS. 6 and 7 show a third embodiment. The drawer body (1 ') of this embodiment comprises first and second drawers.
The back plate (2) of the drawer main body (1) in this embodiment is turned upside down and fitted and fixed to the front opening of the article storage section (3). The structure of the back plate (2) itself is the same as that of the first and second embodiments, and the same reference numerals indicate the same parts.

The front plate (31) is made of wood, and on the rear surface,

Is fixed. In this embodiment, the handle portion (35) of the front plate (31)
This is an example in which the fitting (34) is attached to the lower end when the fitting (25) cannot be attached to the upper end because it is located at the upper part.

[0030]

The present invention has the following effects. (a) Since the front edge of the back plate does not need to be brought into contact with the back surface of the front plate of the front plate, there is no adverse effect on the front plate surface of the steel front plate.

(B) Even on a front panel of a thick decorative board made of wood or resin, the front panel can be superimposed on the back panel without changing the external dimensions by the same means as that of steel.

(C) Regardless of the material of the front plate, the drawer body can be formed in a fixed shape, so that a standardized drawer body can be adopted for the front plate (decorative plate) corresponding to various designs. Reduce prices and facilitate inventory management.

(D) Since the connecting structure is composed of a portion having a shape such that the horizontal tongue and the engaging hole can easily be processed with sufficient accuracy, a margin of dimensional error can be sufficiently obtained in a fitting portion where the processing accuracy is low. Therefore, processing becomes easy, and it is difficult to produce defective products.
