Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to improve the degree of closing of the rack when the rack is stored in furniture or the like having a rack that can be freely drawn out.

Conventionally, furniture has been equipped with racks that can be freely drawn out, but when these racks are put in and stopped inside the cabinet, the inertia of the rack applies a shock to the cabinet, causing a large impact. There were problems such as vibration and noise being generated and the strength of each part of the furniture being affected. In addition, the impact when stopped becomes a repulsive force that causes the rack body to open in the opposite direction, resulting in the problem that the rank body cannot be completely closed.

The present invention aims to solve such problems, and one embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In FIGS. 1 and 2, reference numeral 1 denotes a cabinet constituting the outer shell of the furniture, and a rack body 3 is attached to it via a slide rail 2 attached to its side wall.

Next, a spring part 4 is attached to the ceiling surface of the cabinet 1, and a roller part 5 is attached to the upper side of the rank body 3.

It is attached to the ceiling surface of the cabinet 1 with screws A7, and an inverted mountain-shaped leaf spring 8 is attached to the base plate 6 with one fixed end using screws B9. Further, 10 is a plywood holder, one of which is attached to the ceiling surface of the cabinet 1 with screws C11. This base plate receiver 10 is provided with an elongated hole A12, and an adjustment screw A13 is tightened to the other end bent portion 14 of the plywood through the elongated hole A12.

Next, a roller 16 is attached to the upper side of the rack body 3, and a long hole B17 is provided in the bottom of the pedestal 16 that supports the roller 16, and is fixed to the rank body 3 by an adjustment screw B18.

Further, 19 is a door attached to the front of the rack body 3,
20 is a totte, and 21 is a rack basket.

In such a configuration, when the rank body 3 is slid from the open state to close it, the roller 15 hits the front inclined portion 22 of the leaf spring, and when the next time the upside-down mountain-shaped leaf spring 8 is pushed up, the leaf spring 8 is pushed up. The free end 23 of the spring slides in the direction of arrow A24 while being pressed against the base plate 6. Next, when the roller 16 passes through the top of the leaf spring 26 and reaches the rear inclined portion 26, the door 19ρ hits the cabinet 1 and the rack body 3 is closed.

Further, by loosening the adjustment screw A13 and moving the base plate 6 in the direction of arrow B27, the amount of spring pushing up of the roller 16 can be varied. Furthermore, by loosening the adjustment screw B18 and shifting the base 16 in the direction of arrow C28, the stopping position of the rear inclined portion 26 of the roller 16 when the shell body is closed can be changed.

With such a configuration, the roller 16 is attached to the front inclined portion 22.
While pushing up the leaf spring from 1 to the apex 25, the inertia of the rack body a is gradually weakened by a reaction force opposite to the inertia of the rack body 3 received from the leaf spring 8, and the inertia becomes smaller 519. The roller 16 passes the apex point 25 just before closing, and a force is applied to close the door 19 in the opposite direction.

In this way, the inertial force when closing the rack body 3 is reduced just before the door 19 closes, thereby preventing the inertial force of the rack body 3 from being instantaneously applied to the cabinet 1 and causing shock or noise. Additionally, the door 19 may open due to the reaction that the door 19 receives from the cabinet 1, but this can also be prevented by the spring force acting in the direction of closing n19 from just before the door 19 closes.

Here, in particular, the leaf spring 8 is fixed at one end and moves freely while being pressed against the plywood at the other end, so when the leaf spring 8 is pushed up by the roller 16, the entire leaf spring bends as an elastic body, so a strong repulsive force of the spring is generated. At the same time, the stress concentration and fatigue of the spring are reduced. As shown in Fig. 4, this is compared to the conventional spring 29, which has one end fixed and the other end completely free during operation.
When pushed by roller 30, the spring becomes like 31,
In this case, stress is concentrated particularly on the spring root portion 32, so
The spring has a lot of wear and its strength is weak.

It also has weak repulsive force.

Compared to such a leaf spring, the leaf spring of the present invention has greater repulsion force, strength, and reliability against fatigue etc. even with the same size spring.In addition, in the conventional example, when the rack is opened, the roller 30 is spring 31
In some cases, when the spring 31 is released, the spring 31 vibrates, causing a chattering sound. If the end 23 is kept in pressure contact with or in contact with the base plate 6, the vibration of the leaf spring 8 will be canceled by the base plate 6 in the above case, and the generation of chattering noise can be prevented. .

As described above, according to the present invention, it is possible to suppress the shock when the rack body is stored, to obtain a reliable door catching effect, and to obtain high reliability for the spring. . In addition, the closing strength and shock absorption capacity of the rack body can be adjusted using a position adjustment mechanism of rollers and springs. In addition, in the example, a spring is attached to the inner wall of the furniture, and a roller is attached to the rack body.
