It is being appreciated.

[0004]

[Problems to be solved by the device]

 By the way, in the conventional structure in which the pop-out prevention structure with an inclined surface is added to the main body rail and the drawer rail, a pair of rails is required on both sides of the drawer, so that not only the assembly work is troublesome, but also the rail manufacturing This has led to a sharp rise in die costs, resulting in an increase in the cost of the drawer.

[0005] Therefore, an object of the present invention is to provide a drawer device that can be easily assembled and at a low cost to manufacture rails, thereby reducing the manufacturing cost.

[0006]

[Means for Solving the Problems]

 This invention was devised to achieve the above-mentioned object, and is characterized in that main body rails are attached to both side plates of the main body of the drawer in which the drawers are stored, and a guide roller is provided at the front end of each main body rail. Wheels running on the main body rail are provided on both sides of the rear end of the drawer, and folding parts supported by the guide rollers are formed on both sides of the drawer by integral molding with the drawer main body. At the front end of each folded-back portion, there is formed a pop-out restricting portion that engages with the guide roller and restricts the pop-out during storage.

Further, according to this invention, a rear stopper portion that engages with the guide roller and regulates the storage amount of the drawer with respect to the storage main body can be formed at the front end portion of the folding portion. .

Further, according to this invention, a front stopper portion that engages with the guide roller and regulates the withdrawal amount of the drawer is formed at the rear end portion of the folding back portion and engages with the guide roller. Then, a pull-in restricting portion that restricts the pull-in of the drawer in the depth direction can be formed.

[0009]

[Action]

 According to this invention, since the folded-back portion is integrally formed by resin molding or the like in the drawer, the rail structure for inserting and removing the drawer is formed only by attaching the main body rail to the side plate of the storage main body. When the drawer is stored in the storage body, the pop-out control section engages with the guide roller, which prevents the drawer from popping out.

Further, according to the present invention, when the drawer is stored in the storage body, the rear stopper portion is engaged with the guide roller, thereby preventing the front plate of the drawer from striking hard against the storage body.

Further, according to this invention, when the drawer is pulled out, the guide roller engages with the front stopper to determine the maximum amount of pulling out, and the pulling-in restricting portion restricts the return in the depth direction. .

【Example】

 1 to 6 show an embodiment of the present invention. The kitchen furniture 2 is provided with a sink 4 and a faucet 6, and a lower storage body 8 is provided with an opening door 10 and a plurality of drawers 12. ． Is provided.

Main body rails 16 and 18 are attached to the side plates 14 and 14 of the storage main body 8, respectively, and a drawer 12 formed integrally by resin molding or the like is provided via these main body rails 16 and 18 so as to be freely inserted and removed. Has been. On one body rail 16, a guide plate having a fixed plate 16a fixed to the side plate 14, a rail plate 16b on which the wheels 32 of the drawer 12 run, and a guide groove 16c engaging with the upper ends of the wheels 32. 16d is provided, and the rail plate 16b and the guide plate 16d are formed by bending from the fixed plate 16a, for example. A guide roller 20 having flanges 20a at both ends is rotatably attached to the front end 16d of the main body rail 16 via a shaft pin 22.

On the other hand, on the other main body rail 18, there are provided a fixed plate 18a fixed to the side plate 14, a rail plate 18b on which the wheels 32 of the drawer 12 travel, and a horizontal plate 18c for restricting upward movement of the wheels 32. A guide roller 24 having a flange portion 24a only on the free end side is rotatably attached to the front end portion 18d via a shaft pin 26.

Folded portions 30, 30 are formed on both sides of the drawer 12 by integral molding with the drawer body 28, and wheels 32, 32 running on the body rails 16, 18 are mounted on both sides of the rear end portion. ing. Further, a mounting convex portion 34 such as a female screw portion is formed on the front surface of the drawer 12 together with the rib 35 so that the front plate 36 can be mounted.

As shown in FIG. 4, each of the folded-back portions 30 is formed with a pop-out restricting portion 38 for restricting pop-out at the time of storage at the front end side, and the storage amount, that is, the storage amount with respect to the storage main body 8, that is, A rear stopper portion 40 that regulates the end of the storage is formed, and a front stopper portion 42 that regulates the amount of pulling out at the time of pulling out is formed on the rear end side, and a retracting regulation portion 44 that regulates the return in the depth direction. Are formed. The front stopper part 42 is formed as an inclined surface convex portion having a height that does not get over the guide rollers 20, 24, and the retracting restricting portion 44 is an inclined surface convex portion having a size that easily surpasses the guide rollers 20, 24 with a light pressing force. Is formed as a part.

In the pop-out restricting portion 38, a pop-out restricting inclined surface 38 a is formed with an inclination toward the rear end side of the drawer 12, and a braking inclined surface 38 b is formed with an inclination toward the front end part of the drawer 12. Has been formed. The inclination angle θ ₂ of the braking inclined surface 38b is set to be slightly smaller than the inclination angle θ _{1 of the} protrusion restricting inclined surface 38a so as not to disturb the smooth guide of the drawer 12 by the guide rollers 20 and 24 as much as possible.

When the drawer 12 is stored from the pulled-out state, the storage speed is reduced in the braking slope 38b region L ₁ , and the centers of the guide rollers 20 and 24 cross the boundary point P and fly-out control slope 38a region L. _When reaching ₂ , the drawer 12 is subjected to the retracting action. Finally, it abuts the rear stopper portion 40 and stops. Even if the drawer 12 tries to pop out due to a reaction when it is stored, the pop-out restricting inclined surface 38a receives a resistance force, so that the pop-out is prevented. Further, since the rear stopper portion 40 has the inclined surface 40a that abuts against the guide rollers 20 and 24, the front plate 36 is prevented from violently colliding with the storage body 8.

The drawer device shown in this example has a function of preventing the drawer 12 from slipping off. That is, one of the folded-back portions 30 is restricted from swinging by the guide groove 16c of the main body rail 16 and the guide roller 20 having the flange portions 20a at both ends. Further, by the flange portion 24a of the other guide roller 24, the other end is folded back from the guide roller 24 by the vibration amplification of the drawer 12 in the pulled-out state, that is, in the state where the wheel 32 and the guide rollers 20, 24 are close to each other. The runout of the portion 30 is regulated, which prevents wheel loss. Further, since the guide roller 24 has the flange portion 24a only on one end side, the assembling tolerance is secured.

As described above, the folded portion 30 is integrally formed with the drawer body 28 by resin molding or the like, and at the same time, the protrusion restricting portion 38 and the like are integrally formed, so that the rail mounting work can be performed only by the storage body 8. In addition, the manufacturing cost can be reduced as compared with the case where the pop-out restricting portion is provided on the rail as a single component.

Although a specific shape is shown in the structure of the folded-back portion 30 in the above example, the invention is not limited to this, and the design can be changed as appropriate within the range in which the above function can be satisfied.

[0022]

[Effect of device]
