Description

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

Conventionally, some furniture has a rack body that can be freely drawn out, but when such a rack body stops inside the cabinet during storage,
The inertia of the rack body applies shock to the cabinet, causing problems such as generating large vibrations and noise and affecting the strength of various parts of the furniture. In addition, the impact when stopped becomes a repulsive force, causing the rack to open in the opposite direction, resulting in the problem that the rack does not close completely.

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 that constitutes the outer shell of the furniture, and a rack body 3 is connected via a slide rail 2 attached to the side wall of the cabinet.
is installed. Next, a spring section 4 is attached to the ceiling surface of the cabinet 1, and a roller section 5 is attached to the upper side of the rack body 3.

In the detailed view of FIG. 3, a base plate 6 has one end attached to the ceiling surface of the cabinet 1 with screws A7, and an inverted mountain-shaped leaf spring 8 is attached to this base plate 6 with one fixed end fixed by screws B9. installed. Also, 10 is a base plate holder, and one is screw C1
1 is attached to the ceiling surface of the cabinet 1. This bed plate receiver 10 is provided with an elongated hole A12, and an adjustment screw A13 is fastened to the bent portion 14 at the other end of the bed plate through the elongated hole A12.

Next, a roller 15 is attached to the upper side of the rack body 3, and a pedestal 16 that supports the roller 15 is attached.
A long hole B17 is provided in the bottom of the rack body 3, and the rack body 3 is fixed to the rack body 3 with an adjustment screw B18.

Further, 19 is a door attached to the front of the rack body 3, 20 is a tote, and 21 is a rack basket. In such a configuration, when the rack body 3 is slid from the open state to the closed state, the roller 15 hits the front inclined portion 22 of the leaf spring, and when the next time the inverted mountain-shaped leaf spring 8 is pushed up, the leaf spring 8 is pushed up. While the free end 23 of the spring is in pressure contact with the base plate 6, the arrow A2
Slide in the direction of. Next, when the roller 15 passes through the leaf spring apex 25 and reaches the rear inclined portion 26, the door 19 hits the cabinet 1 and the rack body 3 is closed.

Also, loosen the adjustment screw A13 and move the base plate 6 to the arrow B2.
By moving in seven directions, the amount of spring pushing up of the roller 15 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 15 when the rack body is closed can be changed.

With this configuration, while the roller 15 pushes up the leaf spring from the front inclined portion 22 to the apex 25, the inertia force of the rack body 3 is reduced by a reaction force opposite to the inertia force of the rack body 3 received from the leaf spring 8. The door 19 is gradually weakened and its inertial force becomes smaller.
The roller 15 passes the apex 25 just before the door 19 closes, 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, so that the inertial force of the rack body 3 is instantaneously applied to the cabinet 1, thereby preventing the generation of 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 the door 19 from just before the door 19 closes.

Here, in particular, the leaf spring 8 is fixed at one end and moves freely while the other end is in pressure contact with the base plate, so when the leaf spring 8 is pushed up by the roller 15, the entire leaf spring flexes as an elastic body, so that it is not a strong spring. In addition to providing repulsive force, stress concentration and fatigue in 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 pressed by the roller 30, the spring becomes as shown in 31, but in this case, stress is concentrated particularly at the spring root 32, so the spring has a large degree of fatigue and is weak in strength. It also has weak repulsive force.

Compared to such springs, the leaf spring of the present invention provides greater repulsion force, strength, and reliability against set, etc., even with springs of the same size.

Further, in the conventional example, when the rack is opened and the roller 30 releases the spring 31, the spring 31 generates vibration.
However, in the present invention, the floating end 23 of the leaf spring is already in pressure or contact with the base plate 6 at the time of initial installation, when the load from the roller 15 has not yet been applied to the leaf spring 8. If it is, in the above case, the vibration of the leaf spring 8 will be
Since it is muffled by the base plate 6, it is possible to prevent the chattering sound from occurring.

As described above, according to the present invention, it is possible to suppress the shock when the rack body is stored, and to obtain a reliable door catching effect.

Moreover, high reliability can be obtained 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 the embodiment, the spring is attached to the inner wall of the furniture and the roller is attached to the rack, but the reverse is also possible.
