Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawer rail mounting structure for slidably guiding and supporting a drawer that is put in and out of a cabinet on both sides of the drawer.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 8 to 10, a drawer rail 4 is fixed to the inner surface of a side plate 2 of a cabinet 1 by screws 6, and the drawer rails 4 are arranged on both sides to form drawer rails 4 on both sides. A structure in which the drawer 10 is slidably supported so as to be drawn from the cabinet 1 is generally known. In this case, the drawer rail 4 is made of a metal having a U-shaped cross section made of metal, and is fixedly attached to the inner surface of the side plate 2 of the cabinet 1 by a screw 6 inserted into a round hole 19 formed in the bottom thereof.

The drawer 10 is a wooden box opening upward.
11 and a wooden front plate 12 attached to the front surface of the box 11. Here, a through hole 20 is formed in the front wall of the box 11,
The front plate 12 is attached to the front surface of the front wall of the box 11 by screws 6 inserted into the through holes 20. And box 11
The drawer rails 13 formed on the outer wall surface are slidably engaged with the drawer rails 4 so that the drawer 10 is supported on both sides by the drawer rails 4, and the drawer 10 is attached to the cabinet 1. The upper and lower stages are arranged.

[0004]

However, in the above-mentioned prior art, it is necessary to accurately determine the mounting height position of the draw-out rail 4 on the inner surface of the side plate 2 of the cabinet 1. Otherwise, the height position of the drawer rail 4 will be different on both sides. If this happens, as shown in FIG. 9, the front plate 12 is tilted, and the gap generated around the front plate 12 when viewed from the front is not uniform,
The appearance of the cabinet 1 was hindered. For this reason, conventionally, the drawer rails 4 on both sides are used.
Are aligned with each other, and the drawer rails 4 are held in the same position and held by hand, and the screws 6 are inserted into the round holes 19 while holding the drawer rails 4 by the hands, and the drawer rails 4 are Was fixed.

[0005] In this case, it is necessary to perform the fixing work with the screw 6 while positioning and holding the drawer rail 4 by hand, and there is a problem that the work is troublesome. or,
When the drawer 10 is attached at an angle, the slide engagement with the drawer rail 4 is not smooth, which causes not only a problem in appearance but also a problem in that the drawer 10 is disturbed. Had occurred. In addition, in order to change and adjust the fixing position after the draw-out rail 4 has been fixed, the draw-out rail 4 has to be removed together with the screw 6, so that there is a problem that a difficult operation is required.

SUMMARY OF THE INVENTION The present invention has been made in order to solve all the problems in the prior art described above, and an object thereof is to accurately position a drawer rail at a predetermined height position and to easily attach and fix it. It is an object of the present invention to provide a drawer rail mounting structure that is most suitable for solving the above-mentioned various problems associated with the drawer inclination.

A dowel hole 3 is provided before and after the side plate 2, and a dowel projection 5 is provided before and after the draw-out rail 4. Further, an elongated hole 7 is formed vertically in the drawer rail 4, and the drawer rail 4 is fixed to the inner surface of the side plate 2 by a screw 6 inserted into the elongated hole 7.

As shown in FIG. 2, the cabinet 1 is a wash basin having a wash basin 8 at its upper end. A storage space is formed below the wash basin 8, and the storage space is divided into left and right sides. I have. An openable and closable door plate 9 is attached to a front opening of one of the divided storage spaces, and drawers 10 are arranged in a plurality of upper and lower stages in the other storage space. Drawer 10 is a wooden box 11 that opens upward
And a wooden front plate 12 attached to the front surface of the box 11. Then, a ridge rail 13 formed on the outer wall surface of the box 11
Are slidably engaged with the drawer rail 4 so that the drawer 10 supports the drawer 10 on both sides thereof.

The draw-out rail 4 is made of synthetic resin and is integrally injection-molded, and has a hollow rail main body portion opened to the back.
And a back plate piece 15 protruding from the upper edge on the back side of the rail main body 14. The ridge rail 13 is slidably engaged along a substantially L-shaped corner formed by the rail main body portion 14 and the back plate piece 15 of the drawer rail 4. At this time, the stopper 16 projecting from the front end portion of the draw-out rail 4 prevents the protruding rail 13 from slipping forward.

The rail body 14 of the drawer rail 4 is
It is reinforced by horizontal ribs 17 provided integrally in the hollow interior and a plurality of vertical ribs 18 provided in the same body. A dowel projection 5 and a long hole 7 are formed at a portion where the horizontal rib 17 and the vertical rib 18 intersect. Each of the dowel projections 5 and the long holes 7 is disposed at appropriate intervals in the front-rear direction of the draw-out rail 4 by three each. The drawer rail 4 is lightweight and manufactured at low cost. The rail main body 14 is hollow but strong, and the dowel projection 5 and the long hole 7 are formed at the intersection of the horizontal rib 17 and the vertical rib 18. Are formed, and the mounting strength through these is also ensured.

The dowel holes 3 formed in the inner surface of the side plate 2 of the cabinet 1 are circular, and three dowel holes 3 are provided in the front-rear direction of the same side plate 2. are doing. Further, the dowel projection 5 is formed in a substantially cross shape in a vertical section, and the upper and lower edges of the vertical piece (the upper and lower portions indicated by a two-dot chain line in FIG. 6) can be easily cut and removed with a cutter or a file. In this case, both upper and lower edges of the vertical piece may be cut, or only one of the upper and lower edges may be cut. The dowel projection 5 is formed in a size suitable for the dowel hole 3 in an uncut state, and when the upper and lower edges of the vertical piece portion are cut, a gap between the upper and lower edges and the inner peripheral surface of the dowel hole 3 is formed. As a result, there is an extra gap that can move up and down. that time,
The horizontal portion of the dowel projection 5 is elastically deformed and curved, and both side edges thereof are slidably contacted with the inner peripheral surface of the dowel hole 3, so that the dowel projection 5 is vertically moved without any trouble.

Therefore, in the drawer rail mounting structure of the present embodiment, the dowel projection 5 is inserted and fitted into the dowel hole 3 so that the drawer rail 4 is accurately and easily positioned at a predetermined height. It is temporarily held. Moreover,
With the drawer rail 4 positioned without being held by hand, a screw 6 can be screwed into the inner surface of the side plate 2 of the cabinet 1 to easily and firmly attach and fix it.
As a result, the drawer 10 is prevented from tilting, the appearance of the cabinet 1 is improved, and the slide operation for putting the drawer 10 in and out is not hindered. or,
Here, the front plate 12 of the drawer 10 is also prevented from tilting,
Gap around the front plate 12 as viewed from the front (upper and lower front plates
12 and a gap between the door plate 9 and the side door plate 9).

Further, in the drawer rail mounting structure of this embodiment, by cutting the outer peripheral portion of the dowel projection 5 at the construction site, the vertical dimension of the dowel projection 5 is changed and adjusted. There is room to move vertically between the dowel hole 5 and the dowel hole 3. Thus, the positioning and holding position of the dowel projection 5 and the dowel hole 3 can be changed and adjusted in the vertical direction, and the mounting height position of the drawer rail 4 can be finely adjusted.
