Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for attaching a decorative front plate for a drawer, and mainly provides a mounting structure for a decorative front plate, which improves the mounting strength and also has a good appearance.

[0002]

2. Description of the Related Art In general, drawers for kitchens, furniture, office equipment, etc. are often constructed by attaching a cosmetic front plate to the front surface of a box-shaped drawer body. By the way, as a conventional manner of attaching the cosmetic front plate, a method of fixing with a screw from the inner surface of the front plate portion of the box-shaped drawer body is adopted.

FIG. 5 is a perspective view showing such a conventional typical mounting mode, and FIG. 6 is an end view of DD in FIG. As shown in FIGS. 5 and 6, screw holes 1a are previously provided at appropriate positions on the front plate 1 of the box-shaped drawer body 100.
However, the cosmetic front plate 200 is screwed by using the screw hole 1a. The position of the screw hole 1a is such that a pulling load in the forward direction is applied to the center of the cosmetic front plate 200 through the handle 7 in order to provide a handle 7 for pulling in and out the drawer in the center of the cosmetic front plate 200. There is also a relationship between the load and the properties of synthetic resins that are generally used, and due to the warp of the front plate for makeup 200 and the front plate portion 1 of the box-shaped drawer body 100, a gap is formed between them. The front plate portion of the box-shaped drawer main body 100 is generally used in order to prevent a phenomenon that occurs and a considerable degree of dispersion is observed particularly in the central portion (hereinafter, also simply referred to as “discrete phenomenon due to warpage of the front panel for makeup”). Screw holes 1a are provided together with the reinforcing ribs 6 at positions of about ½ to ⅔ from the center of the 1 toward the left and right ends.

However, in general, the cosmetic front plate 200 has various designs depending on the purpose of use, the variety of designs, and the requirements of the delivery destination. On the other hand, in recent years, the box-shaped drawer body 100 is often integrally formed by injection molding using a synthetic resin, and the position of the screw hole portion 1a is a reinforcing rib at the design stage of a mold used for injection molding. 6
Is defined as a predetermined position together with the position of. Therefore, it is technically difficult and costly to change the position of the screw hole 1a depending on the type of various designs of the decorative front plate 200.

Therefore, depending on the design of the cosmetic front plate 200, the part of the cosmetic front plate 200 corresponding to the position of the screw hole 1a pre-drilled in the front plate part 1 of the box-shaped drawer body 100. In some cases, the wall thickness is too small to prevent good screwing. For example, a cosmetic front plate (see FIGS. 1 and 2) having a frame-shaped design, which is often used as the cosmetic front plate 200, has a large peripheral thickness, but the other parts have a thicker wall thickness. It often happens that it is difficult to fix small screws.

When the strength of attachment of the cosmetic front plate 200 to the box-shaped drawer main body 100 is not sufficient, and when the drawer 7 is repeatedly taken in and out by the handle 7 attached to the cosmetic front plate, the cosmetic front plate 200 is a box-shaped drawer body 1
The phenomenon of leaving from 00 was also seen. This is because the conventional screw hole 1a is provided vertically to the front plate of the box-shaped drawer body 100, and when the cosmetic front plate 200 is pulled vertically vertically, the cosmetic front plate is box-shaped. The cause is that the strength that does not separate from the drawer body, that is, the vertical tensile strength is weak. Furthermore, the conventional manner of attaching the cosmetic front plate 200 has an external problem that the screw head is exposed on the inner surface of the box-shaped drawer body 100. For this reason, in some cases, a step of covering the screw head from the surface while providing a recess for blinding the screw head on the inner surface of the front plate portion of the box-shaped drawer body may be adopted.

[0007]

SUMMARY OF THE INVENTION In view of the above situation, the present invention was made with the intention of first improving the attachment strength of the cosmetic front plate. That is, when the cosmetic front plate is attached to the box-shaped drawer body, the cosmetic front plate can be easily attached while ensuring sufficient strength even if the cosmetic front plate is in the form of a frame or in other forms. It is an object of the present invention to provide a mounting mode in which the vertical tensile strength of is significantly improved as compared with the conventional mounting method. Furthermore, it is another object of the present invention to provide a novel attachment mode in which the screw head for attaching the cosmetic front plate is not exposed on the inner side surface of the box-shaped drawer body and is excellent in appearance.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention fundamentally revises the conventional mounting mode in which a screw for mounting a cosmetic front plate is fixed from the inner surface of a box-shaped drawer body. , It was made by changing the idea of screwing the outside of the box-shaped drawer body. That is, according to the present invention, a collar portion extending left and right is attached to both ends of the front plate portion of the box-shaped drawer body, and a makeup having a length extending from the back surface of the collar portion to the left and right collar portions by means of screw fixing means. This is a structure for attaching a cosmetic front plate for a drawer, characterized in that the front plate for use is fixed to the front surface of the box-shaped drawer body.

Further, it is particularly recommended that the direction of the screw hole formed in the flange is such that the screw hole is inclined outward from the front surface to the back surface of the flange portion. Furthermore, in order to prevent misalignment as well as positioning between the box-shaped drawer body and the cosmetic front plate when fixing with screws, the front surface of the box-shaped drawer body including the collar and the back surface of the cosmetic front plate are included. It is preferable that a protrusion-shaped or concave-shaped locking portion for preventing displacement is provided on the surface. Furthermore, in order to prevent the discrete phenomenon due to the warp of the cosmetic front plate or the like, a warp preventing screw hole portion of the cosmetic front plate or the like is provided in the substantially central portion of the front plate portion of the box-shaped drawer body, if necessary. There is also provided a mode in which the inner surface of the front plate portion is formed in a non-penetrating state. Also,
There is also provided a mounting structure for a cosmetic front plate of a drawer, in which a substantially central portion of the cosmetic front plate is screwed to the box-shaped drawer body through the warp preventing screw hole.

[0010]

In the present invention, at the positions of the brim portions extending left and right at both ends of the front plate portion of the box-shaped drawer body, the cosmetic front plate having a length extending over the left and right brim portions is screwed. Therefore, even if the front face plate for makeup is frame-shaped, the portion with a large thickness is located in the collar portion and is screwed in the portion with a large thickness, so sufficient mounting strength is ensured and A face plate can be attached.

In general, the vicinity of the left and right end portions of the cosmetic front plate is usually not so thin that it can be applied to various designs of the cosmetic front plate. It can be mounted on the box-shaped drawer body with sufficient mounting strength.

Further, the screw head may be exposed on the inner side surface of the box-shaped drawer body as in the conventional case in order to fix the screws from the back surfaces of the flanges attached to both outer sides of the front plate of the box-shaped drawer body. Absent.

Further, in a mode in which the direction of the screw holes formed in the flange is inclined outward from the front surface to the back surface of the flange portion, the screw fixing direction in the left and right flange portions is set. However, since the front ends of the cosmetics are clamped from both sides in such a manner that the tips of the screws are close to each other and converge, in contrast to the conventional case where screws are vertically fixed to the cosmetic front plate. The vertical tensile strength of the cosmetic front plate is remarkably improved. Furthermore, by providing a convex or concave misalignment preventing engagement portion that engages with each other on the front surface of the box-shaped drawer body including the collar portion and the rear surface of the cosmetic front plate, It is possible to effectively prevent the positional deviation between the box-shaped drawer main body and the cosmetic front plate when the screwing is performed by inclining the direction of the stopper.

When the cosmetic front plate is screwed at the positions of the flanges at the left and right ends, and when the above-mentioned discrete phenomenon due to the warpage of the cosmetic front plate occurs, the front of the box-shaped drawer body Correcting the warp of the cosmetic front plate, etc. by screwing the approximately central part of the cosmetic front plate to the box-shaped drawer body through the warp prevention screw hole formed in the substantially central part of the plate part. The discrete phenomenon can be prevented.

The present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a typical embodiment of the present invention,
2 and 3 are an AA end view and a BB end view in FIG. 1, respectively. As shown in these drawings, a collar part 110 extending left and right at both ends of the front plate part 1 of the box-shaped drawer body 100.
Generally, a plate-shaped brim is attached.

The present inventor has previously proposed a device relating to a drawer guide mechanism as a utility model registration application No. 92140 in 1991, in which the upper ends of the left and right side plates 2 of the box-shaped drawer body are folded back. An embodiment is used in which the roller is mounted in the downward groove formed. In the case of the drawer body of this aspect, the collar portion 11 according to the present invention
It is better in terms of handling that 0 is formed as a flange portion that is extended to the left and right by a length that is approximately the same as the width of the groove portion, because only the flange portion does not project. Also, the collar part 1
The attachment of 10 may be performed in a separate step after the box-shaped drawer body 100 is formed. However, when the box-shaped drawer body is molded using a synthetic resin, the collar portion is attached by an injection molding method or the like. It is desirable that the box-shaped drawer body is integrally molded.

In the present invention, the cosmetic front plate 200 having a length extending over the left and right flanges is positioned on the front surface of the box-shaped drawer body 100 and fixed from the back surface of the flange 110 by the screw fastening means. As described above, by fixing the cosmetic front plate with screws at the positions of the brim portions that extend to the left and right at both ends of the front plate portion of the box-shaped drawer body,
Even a frame-shaped cosmetic front plate having a small thickness other than the periphery as shown in FIG. 2 can be attached to the box-shaped drawer body with sufficient strength.

The term "screw stop" in the present specification refers to not only the wood screw including the screw 5 but also the case of fixing using a dowel, etc. Preferably used.

The collar 110 is usually provided with a screw hole 110a for facilitating screw fixing work.
The direction of the screw hole 110a is as shown in FIG.
As shown in B end view), it is particularly preferable and recommended that the flange 110 is provided so as to be inclined outward from the front surface to the back surface. The degree of inclination is determined by the front plate 200 for makeup.
The vertical tensile strength of the cosmetic front plate can be sufficiently improved by inclining it in the range of 5 to 45 degrees with respect to the vertical direction, and usually in the range of 10 to 30 degrees. Further, by providing such an inclination, it is possible to operate the grip portion of the driver at a position apart from the side plate 2 of the box-shaped drawer body to some extent during screw fastening work, which is also advantageous in terms of workability. .

The screw hole 110a may be inclined in the vertical direction together with the horizontal direction. In particular, a mode in which the collar 110 is inclined downward from the front surface to the back surface is a driver. It is possible to operate the grip portion at a position apart from the folded-back portion of the upper end of the side plate of the box-shaped drawer body to some extent, which has the advantage of further facilitating the screw fastening work. Further, when the screw holes 110a are provided so as to be inclined, the collar portion 110 is positioned to prevent the positional deviation as well as the positioning between the box-shaped drawer body 100 and the cosmetic front plate 200 during the screw fastening work. It is recommended that a convex or concave locking portion for preventing misalignment is provided on the front surface of the box-shaped drawer body 100 and the back surface of the cosmetic front plate 200 including the above.

As shown in FIG. 1, the locking portion for preventing displacement is generally provided with a dowel 3a on the front surface of the box-shaped drawer body including the collar portion, and the dowel 3a is provided on the rear surface of the front plate for makeup. A mode in which a recessed portion 3b that engages with the dowel is provided, or
On the contrary, a mode in which a dowel is provided on the surface of the rear surface of the front plate for makeup and a corresponding recess is provided on the surface of the flange or the like is preferably adopted.

Further, the cosmetic front plate 200 is fixed with screws at the positions of the collar portions 110 at the left and right ends,
If there is a possibility that the above-mentioned makeup front plate or the like causes a discrete phenomenon due to the warpage, a warp prevention screw such as the cosmetic front plate 200 may be provided at substantially the central portion of the front plate portion 1 of the box-shaped drawer body, if necessary. It is advisable to provide the holes 4. FIG. 4 is a C-C end view in FIG. 1. As shown in FIGS. 1 and 4, the warp prevention screw holes 4 are usually formed in the front plate portion 1 of the box-shaped drawer body.
It is recommended that the inner side surface of the front plate portion be perforated without being penetrated because the opening portion of the warp preventing screw hole portion is not seen on the inner side surface of the front plate portion and the appearance is not spoiled. The warp prevention screw holes 4 are generally not used in ordinary cases, but when the cosmetic front plate 200 is attached to the box-shaped drawer main body 100 with screws via the flanges 110 at the left and right ends, it accidentally happens. If a discrete phenomenon occurs due to the warpage of the front panel for makeup,
The hole 4 for the warp prevention screw is penetrated through the whole, and the inner surface of the front plate portion 1 of the box-shaped drawer body is screwed to the substantially central portion of the front plate 200 for cosmetics to correct the warp and prevent the discrete phenomenon. It is intended.

By adopting the attachment structure for the decorative front plate of the drawer of the present invention as described above, the attachment strength of the decorative front plate is significantly improved. That is, even if the cosmetic front plate has a frame shape or other form, it can be easily attached while ensuring sufficient strength, and the vertical tensile strength of the attached cosmetic front plate is compared with conventional attachment methods. improves. In particular, the vertical tensile strength of the cosmetic front plate is remarkably improved by providing the screw holes in an inclined direction. The improvement of the vertical tensile strength has a great practical significance because it also affects the service life of the article stored in the drawer when the article has a considerable weight or a large drawer. Further, in the present invention, the screw head, which was conventionally exposed on the inner surface of the box-shaped drawer body, is not exposed at all and is excellent in appearance, and the drawer was conventionally used to prevent the screw head from protruding. There is no need to make a recess on the inner surface of the body. Further, by providing the locking portion for preventing the positional deviation, the positional deviation during the screw fixing work can be effectively prevented, and by tilting the direction of the screw hole portion, the driver's operation can be facilitated, which has many advantages. . Furthermore, in the aspect in which the warp-preventing screw holes of the cosmetic front plate etc. are provided, it is possible to easily correct the warp and prevent the discrete phenomenon even when the discrete phenomenon occurs, which is significant in quality control.
