Description

Description: TECHNICAL FIELD The present invention relates to a drawer in which a rail is attached to a drawer box.

2. Description of the Related Art As shown in FIG. 9, a conventional drawer of this type engages a pair of rails 2 fixed to both sides of the bottom of a drawer 1 with a pair of guides 4 arranged on the cabinet 3 side. By doing so, the drawer 1 is inserted into and pulled out of the cabinet 3.

As shown in FIG. 10, the pull-out member 1 and the rail 2 are attached by inserting the locking piece 5 and the stopper 6 into the locking hole 7 of the rail 2 and then sliding the rail 2 in the forward direction of the pull-out. The rail 2 was fitted and fixed in the gap between the piece 5 and the bottom of the drawer box.

Problems to be Solved by the Invention In such a conventional configuration, when a slight shift occurs in the mounting position of the guide 4 to the cabinet 3, the engagement between the rail 2 of the drawer 1 and the guide 4 does not work well. Or the drawer body 1 swings to the left or right due to this, or the friction between the rail 2 and the guide 4 increases, so that the drawer body 1 cannot be smoothly inserted or removed.
There has been a problem that the rail 2 and the guide 4 may be damaged.

The present invention solves such a problem, and can easily adjust even if the drawer is rattled.

Means for Solving the Problems The drawer of the present invention is configured such that a guide is fixed to an inner wall of a cabinet, the guide is engaged with a rail fixed to the drawer, and the drawer is configured to be able to be pulled out from the cabinet, and the rail is provided. And a substantially L-shaped portion of a substantially L-shaped locking piece provided at the bottom of the drawer box of the drawer is fitted to a hole edge of the locking hole, and the rail is provided on the inner wall of the cabinet. The width of the locking piece of the rail is smaller than the width of the locking hole so as to be able to approach and separate from the guide. Also, a fitting piece having a fitting groove is provided on the rail, and a fitting projection is provided at a position of the bottom of the drawer box opposite to the fitting groove, and the fitting piece is provided at the bottom of the drawer box. It is bent toward.

In the drawer of the present invention, the substantially L-shaped portion of the substantially L-shaped locking piece provided at the bottom of the drawer box of the drawer is fitted into the hole edge of the locking hole, and the rail is formed on the inner wall of the cabinet. The width of the locking piece of the rail is made smaller than the width of the locking hole so that the rail can be moved close to and away from the guide. Within the range of the width dimension difference between the guides. In addition, since the locking piece is formed in a substantially L-shape and bent forward, the rail is pulled out from the front of the box body and slid rearward, and then the front plate is mounted on the front part of the drawer box. It can be reliably prevented from slipping back and forth from the drawer box, and safe use can be achieved.

Further, the rail is provided with a fitting piece having a fitting groove, and a fitting projection is provided at a position opposite to the fitting groove at the bottom of the drawer box, so that the mounting state is strong against a lateral force. Therefore, it is possible to reliably prevent the rail from shifting during the normal pull-out operation. Further, since the fitting piece is bent toward the bottom of the drawer box, it is possible to realize an engagement state in which the bottom of the drawer box is pressed down, and the rail can be more reliably prevented from being displaced.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIGS. 1 to 6 show an embodiment of the present invention. In the drawer, a drawer 11 is attached to a cabinet 10 so as to be freely inserted and removed.

A pair of guides 12 are provided on both inner sides of the cabinet 10, and the drawer 11 includes a drawer box 13, a front plate 14, and a pair of metal rails 15.

On both sides of the bottom of the drawer box 13, locking pieces 19 each having a substantially L-shaped side surface are formed so that the hooked portions extend in the front plate 14 direction.

The rail 15 has a locking hole 16 for engaging with the locking piece 19 and a fitting piece 21a bent toward the bottom of the drawer box 13.

A mounting hole 18 is formed in the front of the drawer box 13 to fix the front plate 14 with screws 17. 22 is a pulley.

In the above configuration, the drawer box 13 bottom locking piece 19 is
After being inserted into the locking hole 16 of the rail 15, the rail 15 was slid backward of the drawer box 13, and the locking hole edge of the rail 15 was fitted and fixed in the gap between the locking piece 19 and the bottom of the drawer box 13. Thereafter, the drawer 11 is completed by attaching the front plate 14 to the drawer box 13 with the screws 17.

The horizontal movement of the rail 15 is achieved by inserting a flathead screwdriver or the like into the gap A shown in FIG. To adjust.

When the fitting piece 21a is bent toward the bottom of the drawer box 13 as shown in FIGS. 5 and 6, the rail 15 can be further pressed against the bottom of the drawer box 13,
15 can be more reliably prevented from shifting.

7 and 8, the fitting piece 21a is provided with a fitting groove 21b, and the fitting protrusion 20 is provided at a position corresponding to the fitting groove 21b on the bottom of the drawer box 13. Since the fitting groove 21b and the fitting projection 20 are fitted in a state where the rail 15 is mounted on the bottom of the box 13, the mounting state becomes strong against a lateral force, and the rail 15 is pulled during a normal pull-out operation.
Can reliably be prevented from shifting in the lateral direction.

As is clear from the description of the embodiments, according to the present invention, the substantially L-shaped portion of the substantially L-shaped locking piece provided at the bottom of the drawer box of the drawer body has the edge of the locking hole. The width of the locking piece of the rail is made smaller than the width of the locking hole so that the rail can freely move close to and away from the guide on the inner wall of the cabinet. In addition, the rail can be moved toward and away from the guide within the range of the difference between the width of the locking hole and the width of the locking piece,
Even if a slight misalignment occurs in the mounting position of the guide mounted on the cabinet, the misalignment can be absorbed by moving the rail mounting position to the drawer body in the horizontal direction, and the rail of the drawer body and the guide can be absorbed. And the pull-out body swings to the right and left due to this, and the friction between the rail and the guide increases, and the pull-out body is not smoothly inserted and removed, which is caused by that. This has the effect of reliably preventing damage to the rails and guides.

Further, in the present invention, the fitting piece having the fitting groove is provided on the rail, and the fitting protrusion is provided at a position corresponding to the fitting groove on the bottom of the drawer box. , And can reliably prevent the rail from shifting during a normal pull-out operation.

Further, since the fitting piece is bent toward the bottom of the drawer box, it is possible to realize an engagement state in which the bottom of the drawer box is pressed, so that the rail can be more securely prevented from being displaced. Things.
