2. Description of the Related Art Conventionally, as a drawer, a synthetic resin rail attached to the inner surface of a main body side of furniture or the like in the front-rear direction has a substantially U-shaped cross section from upper and lower surfaces and a mounting surface, and a lower surface has an upper surface. A notch is formed in the front-rear direction shorter than the front portion, a notch is formed in front of the front end portion, a bulging portion is formed on the lower surface of the front end portion, and is close to the lower wall of the concave groove. While the protrusion is formed, a drawer stopper that collides with the rear end of the stopper protrusion is formed on the outer surface of the drawer or the like, and when the drawer is stored, the back surface of the front plate of the drawer collides with the front end surface of the rail. And stopped. (For example, the actual fair 5-452
No. 56)

On the other hand, as a drawer which is generally easy and inexpensive to manufacture, a flexible film sheet is laminated on the surface of a substrate, and a part of the flexible film sheet is left on the substrate.
There is provided a body in which a front plate is dowel-joined to a body formed by forming a V-shaped groove, bending the V-shaped groove, and bonding both inclined surface parts together.

[0004]

When such a drawer is used together with the above-mentioned rail, when the drawer is vigorously stored, for example, when a heavy object is stored inside the drawer, the drawer front plate is attached to the front end of the rail. If the drawer stops suddenly due to the collision of the back surface of the body, the stored items may move rearward due to inertia and collide with the rear plate of the body. Then, due to the impact at this time, there are problems such as the dowel joint between the body and the front plate being detached, the abutting portion of the body being detached, the flexible film sheet being torn, and the rear plate of the body being detached. Was.

The present invention provides a drawer device which has a simple structure, is manufactured at a low cost, and does not cause the front plate to come off or damage the trunk portion of the drawer even if the drawer is conventional. Make things an issue.

[0006]

Therefore, the present invention is configured as a first means in that an inner surface of a main body side of furniture or the like is provided with:
In a drawer comprising a synthetic resin rail mounted in the front-rear direction and a front-rear groove formed on a side surface of a side plate such as a drawer fitted to the rail, a height of the groove is provided at a rear end of the rail. The present invention is characterized in that the rear stopper is formed integrally with the rail, having a size larger than the height, protruding in the vertical direction of the rail, and contacting the rear surface of the body of the drawer when the drawer is stored.

Further, the present invention is configured as a second means in that the rail is formed to have a substantially U-shaped cross section from the upper and lower surfaces and the mounting surface, and is positioned in front of the rear stopper so that the groove is not formed when the drawer is stored. The point is that a brake projection elastically contacting the bottom surface is formed integrally with the rear end of the mounting surface.

Further, the present invention is configured as a third means in that the upper and lower surfaces and the mounting surface have a substantially U-shaped cross section, the lower surface is shorter in the front-rear direction than the upper surface, and a notch is formed in front of the front end. A bulge is formed on the lower surface of the front end near the lower wall of the concave groove, and a stopper protrusion is formed on the front end of the upper surface, and a stopper protrusion is formed on a side surface of the side plate of the drawer. In that a draw-out stopper colliding with the rear end of the portion is formed.

[0009]

According to the first feature of the present invention, when the drawer is stored, the rear surface of the body collides with the front end of the rear stopper, and the movement of the drawer stops.

According to a second feature of the present invention,
When the drawer is stored, before the rear surface of the body collides with the front end of the rear stopper, the brake projection elastically contacts the bottom surface of the concave groove, and the storage speed of the drawer is reduced.

According to a third feature of the present invention,
With the drawer pulled out most forward, the upper wall of the groove contacts the upper surface of the rail, and the rear end of the lower wall of the groove contacts the lower surface of the bulge.

Embodiments will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a synthetic resin rail attached to the inner surface of the main body 10 of furniture or the like, and in FIG. 2, reference numeral 2 denotes a drawer.

The rail 1 has a substantially U-shaped cross section including upper and lower surfaces 11, 12 and a mounting surface 13, and a lower surface 12 is formed shorter in the front-rear direction than the upper surface 11.

A cutout portion 14 for extracting the drawer 2 is formed in front of the front end of the lower surface portion 12, and the rear of the cutout portion 14 is inclined upward and forward at the rear of the cutout portion 2.
Guide wall 1 that projects to the side and serves as a guide when the drawer 2 is mounted
5 is connected to the front end of the lower surface portion 12.

A bulging portion 16 protruding downward is formed on the lower surface of the front end of the lower surface portion 12 in the vicinity of a lower wall 25 of a groove 22 formed in the body 20 of the drawer 2 described later.

A stopper projection 17 is formed at the front end of the upper surface 11 so as to be located above the main body 10 of furniture or the like and project upward.

A groove 2 is provided at the rear end of the upper and lower surfaces 11, 12.
The rear stopper 3 has a height dimension larger than the height dimension of the drawer 2 and abuts against the rear surface of the body 20 when the drawer 2 is stored.

Further, at the rear end of the mounting surface portion 13 and in front of the rear stopper 3, when the drawer 2 is stored,
Are formed integrally with the bottom portion 221 of the base member.

Reference numeral 18 denotes a front end reinforcing portion of the upper surface portion 12, and reference numeral 19 denotes a front reinforcing portion of the mounting surface portion 13. Then, the rail 1 is fixed to the inner surface of the main body side 10 of the furniture or the like by attaching the mounting surface portion 13 with a tucker or the like.

The drawer 2 is formed by a body 20 and a front plate 5, and the body 20 and the front plate are connected by a dowel joint. The body 20 has a V-shaped groove formed on a substrate having a flexible film sheet laminated on a surface thereof, leaving a part of the flexible film sheet, and bending the V-shaped groove to form an inclined surface. A rear plate 201, left and right side plates 202, which are bonded to each other with an adhesive, and a rear plate 201, and a bottom plate 203 fixed to the left and right side plates 202 are formed. A plurality of dowels project from the front ends of the left and right side plates 202 and are joined to the front plate 5.

The side plate 202 is formed with a groove 22 extending in the front-rear direction, and a pull-out stopper 23 projecting outward at a rear end of the side plate 202 above the groove 22.

On the other hand, the interval between the upper wall 24 and the lower wall 25 of the groove 22 is slightly larger than the interval between the upper and lower portions 11 and 12 of the rail 1, and is substantially equal to the interval between the upper portion 11 and the bulging portion 16. ing.

That is, when the dimension between the upper and lower surfaces 11 and 12 is set to the dimension between the upper and lower surfaces 11 and the bulging portion 16, the rail 1 is caused by warping in the front-rear direction of the rail 1 generated during molding.
However, there is a problem that the groove 2 cannot be fitted into the groove, and smooth sliding cannot be obtained.

On the other hand, if the dimension between the upper and lower surfaces 11 and 12 is set smaller than the dimension of the groove 22 in anticipation of the warpage at the time of molding, smooth sliding can be obtained, but the groove 22 and the rail 1 cannot be moved.
Vertical play is caused by the gap, and further, the drawer 2 is extremely lowered forward in a state where the drawer 2 is pulled out most (a state in which the drawer stopper 23 collides with the stopper projection 17).

The present invention is constructed as described above,
When the groove 22 is fitted on the rail 1, it slides in the front-rear direction, and when it is pulled out most, the pull-out stopper 23 collides with the stopper projection 17 and stops.

Then, in this state, the upper wall 24 of the groove 22 is formed.
Is in contact with the upper surface 11 of the rail 1, the rear end of the lower wall 25 contacts the lower surface of the bulging portion 16, and the drawer 2 hardly falls forward.

When pulling out the drawer 2, the front end of the drawer 2 is lifted and the stopper 23 is moved to the stopper projection 1.
7 while pulling it out.

At this time, the lower surface 12 of the rail 1 is moved to the upper surface 11
Since the cutout portion 14 is formed to be shorter, the upward inclination of the drawer 2 is smoothly performed.

On the other hand, when the drawer 2 is mounted and stored, the groove 22 and the rail 1 are fitted by the reverse operation.
At this time, the guide wall 15 guides the rear end surface of the lower wall 25 of the concave groove 22. When the drawer 2 is stored, the brake projection 4 elastically contacts the bottom surface 221 of the concave groove 22 just before the drawer 2 is completely stored, and the storage speed is reduced.

When the drawer 2 is completely stored, the rear surface of the body 20 of the drawer 2 (the rear surface of the left and right ends of the rear plate 201) collides and stops, and the drawer 2 is in the stored state.

【The invention's effect】

(1) According to the present invention, since the rear stopper 3 is formed integrally with the rail 1 by a synthetic resin,
It is very easy to manufacture, and as in the conventional case, there is no new work other than the work of attaching the rail 1, so that it can be manufactured at low cost.

The rear stopper 3 is larger than the height of the groove 22 and is formed at the rear end of the rail 1 so as to protrude in the vertical direction. When a heavy object is stored inside the drawer 2 and the heavy object moves and collides with the rear plate 201 due to the stop of the drawer 2, the impact is applied to the rails through the rear plate 201. Since it can be received by the stopper 3 after 1
Since the rear plate 201 or the torso 20 does not move backward, the abutting portion of the rear plate 201 and the side plate 202 of the torso 20 is disbonded, the flexible film sheet is torn, and the rear plate 201 comes off. Or front panel 5 and torso 2
The dowel joint of 0 does not come off.

(2) According to the second aspect of the present invention,
In addition to the effect of the above (1), by making the upper and lower surfaces 11, 12 and the mounting surface 13 substantially U-shaped in cross section, a space for forming the elastically provided brake projection 4 can be formed between the upper and lower surfaces 11, 12. Thus, the brake projection 4 can be formed integrally with the rail 1 from synthetic resin. In addition, brake projection 4
Is formed on the front side of the rear stopper 3 and elastically contacts the bottom surface 221 of the concave groove 22 when the drawer 2 is stored. Therefore, even if the drawer 2 is stored vigorously, the speed is appropriately reduced. Extremely low collision noise during storage. When the drawer 2 is stored, the brake projection 4 is
, The stability in the left-right direction at the storage position of the drawer 2 is improved.

(3) According to the third aspect of the present invention,
In addition to the effects of the above (1) and (2), since only the bulging portion 16 is close to the lower wall 25 of the concave groove 22, the warpage of the rail 1 generated at the time of molding can be absorbed, and the smoothness can be obtained. Sliding can be obtained, and rattling of the drawer 2 up and down, and forward fall of the drawer 2 in the most extended state can be prevented.
