DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a drawer mounting structure widely applicable to wagons, cabinets, desks and the like.

[0002]

2. Description of the Related Art For example, as one of the structures of a wagon, a suspension rail mechanism is provided on inner surfaces of left and right side walls of a wagon body, and a drawer is attached to a tip rail of the suspension rail mechanism. 2. Description of the Related Art There is known a wagon that can be pulled out from a storage position in a wagon body forward by using an operation of a rail mechanism.

[0003]

By the way, as a structure for mounting the drawer to the wagon main body, a first bracket is mounted on an inner surface of a side wall of the wagon main body, and a main body rail is mounted on an inner end side of the first bracket. While supporting
Usually, a drawer rail is engaged with the inside of the main body rail so as to be movable back and forth, and the drawer is attached to the drawer rail via a second bracket.

However, with such a structure, when the drawer is pulled out, the drawer rail or the like is exposed on the side wall of the drawer, and not only the appearance is impaired, but also the drawer rail and the main body are mixed by dust. Inconveniences may occur, such as sliding resistance between the rails, accidental collision of articles and damage to the rail mechanism components. Therefore, in some conventional drawers, a cover is attached to the side wall, and the cover conceals the drawer rail and the like. However, in this case, not only the cover but also a component for attaching the cover are separately required, which inevitably leads to an increase in man-hour and cost.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a drawer mounting method capable of concealing a drawer rail or the like with a small number of parts without deteriorating the mounting strength of the drawer. It seeks to provide structure.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS For this purpose, a drawer mounting structure according to the present invention is a main body rail in which a drawer is engaged with a furniture body so that upper edges and lower edges of upright walls of each other can be moved back and forth. And when mounting via the drawer rail, a first bracket is attached to the inner surface of the side wall of the furniture main body, and the upright piece formed on the inner end side of the first bracket supports the upright wall of the main body rail, The drawer rail is engaged with the outside of the main body rail, and the upright piece of the second bracket is raised at a position where at least the drawer rail can be covered while being supported by the upright wall of the drawer rail. The drawer is attached to the upper end of the upright piece of the second bracket.

With this configuration, the drawer rail always moves back and forth with the drawer while being concealed by the second bracket, so that at least the drawer rail is exposed,
It is possible to effectively prevent the drawer from deteriorating in appearance and causing malfunctions and failures. In addition, the second bracket is originally used to support the drawer on the drawer rail, and since the second bracket also serves as a cover, it is not necessary to use a separate cover. In addition to this, the mounting state as a cover can be ensured.

According to the present invention having such an operation and effect, the upright walls of the main body rail and the drawer rail are supported by both the upper edge and the lower edge so that the upright walls can properly receive the vertical load. Since the first and second brackets effectively support the vertical load mainly by the compressive strength of the member of the upright piece attached to the upright wall, the first and second brackets have a flexural rigidity with respect to the overload. The structure can be high. In addition, the shape of the bracket for supporting one of the standing pieces on the side wall of the furniture main body and supporting the other on the drawer can be a simple one that does not require another member to be interposed in the middle. It can be made of a single member to eliminate the need for welding and the like, and to improve the coverage of the coating. In particular, since the second bracket plays a role as a cover, the merit of good painting is great.

In order to more effectively increase the bending rigidity with respect to the second bracket, a part of the side wall of the drawer is formed in the second bracket.
It is desirable that the bracket be placed near the upper end of the upright piece. When the lower end of the upright piece of the first bracket is configured to be attached to the inner surface of the side wall of the furniture body via the horizontal piece, in order to more effectively increase the bending rigidity with respect to the first bracket, these upright pieces and It is preferable that a bent reinforcing portion for maintaining the angle between the upright piece and the horizontal piece at a substantially right angle is formed at the intersection with the horizontal piece.

That is, according to the present invention, the main body rail is cantilevered at the inner end of the first bracket, and the main body rail is disposed inside the drawer rail, that is, on the drawer side, contrary to the conventional case. Since the inner end of the first bracket is extended to a position relatively protruding from the side wall of the furniture main body, the overload normally acts as a larger bending moment. However, the present invention
The first bracket is composed of a horizontal piece and an upright piece that rises from the inner end of the horizontal piece to the mounting position of the main body rail, and a crossing angle between the horizontal piece and the upright piece is maintained. At the same time as forming a reinforced part that contributes to
Since the substantial extension of the horizontal piece is shortened by the bent reinforcing portion, the deformation of the first bracket can be prevented beforehand, and the proper mounting strength of the drawer can be maintained.

A preferred embodiment of the present invention is one in which the bending reinforcing portion has a shape bent at an angle. In order to obtain a simple structure, it is desirable that the standing piece, the horizontal piece, and the bending reinforcing portion are integrally formed by bending a sheet metal material. In order to more effectively increase the support strength, it is preferable that a lower edge of the main body rail is provided on the upper surface of the bent reinforcing portion.

In a preferred embodiment of the present invention, the drawer rail is a tip rail constituting a suspension rail mechanism. In that case, it is effective to configure the main body rail as a base rail constituting the suspension rail mechanism and to allow the second bracket to cover the intermediate rail interposed between the base rail and the front rail. Become.

The first and second brackets 5 and 4 mainly include the upright wall 3.
Since the vertical load is supported by the compressive strength of the members of the upright pieces 51 and 41 attached to the 2c and 31c, a structure having high bending rigidity with respect to the overlaid load is realized, and the proper function of the drawer is ensured. Can be. In addition, the bracket shape of the present embodiment for supporting one of the standing pieces 51 and 41 on the side wall 11 of the wagon main body 1 and supporting the other on the drawer 2B is a simple shape that does not require another member to be interposed in the middle. Therefore, it can be made of a single member to eliminate the need for welding and the like, and to improve the coverage of the coating. In particular, since the second bracket 4 serves as a cover,
According to the present embodiment, the function can be effectively secured.

In particular, in this embodiment, the side wall 21 of the drawer 2B is
And the drawer 2B is connected to the horizontal piece 42 of the second bracket 4 through the reinforcing frame 23.
And the reinforcing frame 2
3 is set near the upper end of the upright piece 41 and
1 as much as possible from the vertical direction, so that the end of the horizontal piece 42 extends to the side wall 21 of the drawer 2 </ b> B and is attached to the second bracket 4.
Can be more effectively increased.

In this embodiment, the lower end of the upright piece 51 of the first bracket 5 is attached to the inner surface 1a of the side wall 11 of the wagon body 1 via the horizontal piece 52. A bent reinforcing portion 54 for maintaining the angle between them at a substantially right angle is formed at the intersection of the horizontal piece 52 and the horizontal piece 52, so that the bending rigidity with respect to the first bracket 5 can be more effectively increased. . That is, in this embodiment,
The inner end of the first bracket 5 supports the base rail 32 in a cantilever manner, and in the present embodiment, the base rail 32
Is disposed on the inner side of the tip rail 31, that is, on the side of the drawer 2 </ b> B, and the inner end of the first bracket 5 extends to a position protruding from the side wall 11 of the wagon body 1 relatively greatly. Therefore, the overload normally acts as a larger bending moment. However, in the present embodiment, the first bracket 5 is
An upright piece 51 that rises from the inner end of the horizontal piece 52 toward a predetermined mounting position of the base rail 32 is provided. The intersection between the horizontal piece 52 and the upright piece 51 contributes to maintaining the crossing angle. Is formed, and at the same time, the substantial extension distance of the horizontal piece 52 is suppressed short by the bending reinforcing portion 54, so that the inner end of the first bracket 5 is moved to the predetermined extension position. , The deformation of the bracket 5 can be prevented beforehand, and the proper mounting strength of the drawer 2B can be secured.

In particular, since the bending reinforcing portion 54 has a shape bent at an angle, the reinforcing structure can be configured very simply. That is, as in the present embodiment, the upright piece 51, the horizontal piece 52, and the bending reinforcing portion 54 can be integrally formed by bending a sheet metal material, so that manufacturing can be extremely simplified. further,
Since the lower edge 32b of the base rail 32 is provided directly above the bending reinforcing portion 54, the support strength for the rail 32 can be more effectively increased.

As described above, the present invention can be extremely useful when applied to the case where the draw-out rail is the tip rail 31 constituting the suspension rail mechanism 3. The above is exactly the same for the drawers 2A and 2C. The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, when the suspension rail mechanism has an intermediate rail between the distal rail and the proximal rail, it is effective to configure the second bracket so as to cover the intermediate rail together with the distal rail. .

[0030]

The present invention is embodied in the above-described embodiment, and has the following effects. That is,
The drawer mounting structure according to the present invention attaches the drawer to the furniture main body so as to be movable back and forth through a main body rail and a drawer rail which are engaged at both upper and lower edges. The first bracket is attached to the inner surface of the side wall of the main body, the erecting piece supports the erecting wall of the main body rail, and the drawer rail is engaged with the outer side of the main body rail to be supported by the erecting wall of the drawer rail. Then, the upright piece of the second bracket is raised at a position where at least the drawer rail can be covered, and the drawer is attached to the upper end side of the upright piece.

For this reason, the second moving back and forth with the drawer
The bracket of the present invention suitably hides the drawer rail, thereby ensuring a good appearance of the drawer and proper operation. In addition, since the second bracket can also serve the same role without using a separate cover member,
The man-hour and cost can be reduced, and the function as a cover can be enhanced. Further, since the load of the drawer is supported mainly by the compressive strength of the members on the upright pieces of both brackets and the upright walls of both rails, the entire mounting structure of the drawer can be made strong in bending rigidity. In addition, since a complicated shape is not required for the bracket, it is possible to effectively improve the convenience of manufacture and the convenience of painting by simplification.

Further, if a part of the side wall of the drawer is mounted near the upper end of the upright piece of the second bracket,
A load can be applied to the bracket from the direction in which bending is unlikely to occur. In addition, when the lower end of the upright piece of the first bracket is attached to the inner surface of the side wall of the furniture main body via the horizontal piece, a bent reinforcing piece is formed at the intersection of the upright piece and the horizontal piece. Even if the inner end of the first bracket is disposed at the predetermined extended position, deformation of the horizontal piece or the upright piece of the bracket can be prevented beforehand, and appropriate mounting strength of the drawer can be secured.

Further, if the bent reinforcing portion is formed in a shape bent at an angle, the reinforcing structure becomes extremely simple. In particular, the standing piece, the horizontal piece and the bent reinforcing portion are integrated by bending a sheet metal material. Molding can reduce the manufacturing cost. Further, if the lower edge of the main body rail is additionally provided on the upper surface of the horizontal portion of the bending reinforcing portion, the supporting strength for the main body rail can be more effectively increased.

Since the present invention has the above-described configuration,
This can be extremely useful when applied to a drawer rail that is a tip rail constituting a suspension rail mechanism. Further, when the suspension rail mechanism has an intermediate rail between the distal rail and the proximal rail,
It is also effective that the main body rail is the base end rail of the present invention and the second bracket can cover the intermediate rail together with the front end rail.
