DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting and lowering mechanism used for storing various items in a kitchen or the like, and more particularly to a stopper for a lifting and lowering storage device.

[0002]

2. Description of the Related Art Conventionally, this type of storage device has been disclosed in, for example, Japanese Patent Application Laid-Open Nos. Sho 60-7808 and 61-154.
No. 610, etc., the storage rack is supported between the free ends of the parallel links on both sides pivotally supported on the inner surfaces on both sides of the storage cabinet, and the storage rack is pulled out to the storage position in the storage cabinet and below the front of the storage cabinet. It was designed to be able to move up and down with the taken-out position.

Further, the parallel link mechanism is provided with a tension spring acting in the direction of lifting the storage rack so as to suspend the storage rack against the load of the storage article and reduce the force required when the storage rack is pushed up from the lowered position to the storage position and stored. There was something that was.

[0004]

However, such a storage rack apparatus with an elevating function has a large shock to the stop mechanism and the elevating link mechanism due to the inertia of the storage load when the storage rack is lowered and stopped. Is added.

[0005] Even in the case of an ascending / descending storage device having a suspension mechanism in which a reaction force spring is disposed against a storage load, the descent speed is suddenly increased by inertia force as in the case where a load exceeding a set load is applied. When the storage rack is stopped, a large shock is applied, causing problems such as noise generation due to vibration and storage items falling due to recoil, and durability such as damage and failure of the lifting mechanism and storage rack part due to impact. There was a problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide an ascending and descending storage device which can be quietly raised and lowered, is easy to use, and has excellent reliability.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a lifting storage device of the present invention supports a storage rack between free ends of parallel links pivotally supported in both side surfaces of a storage cabinet. in lifting accommodating apparatus capable of lifting between a storage position within the storage cabinet and pulled out position drawn out forwardly downward from the storage position, metal
And made to adhere to the surface of the bent-up piece
A rubber-like shock absorber and, furthermore, this shock absorber
A metal press plate that covers almost the entire surface is fixed.
With a stopper to stop the vertical movement of the storage rack
There is a configuration.

[0008]

According to the above construction, the lifting and lowering storage device of the present invention can
Since the link abuts against the pressing plate that covers the upper surface of the shock absorber of the stopper, and the entire surface of the pressing plate compresses and stops the shock absorber over the entire surface, the shock absorbing effect is extremely large.

Accordingly, noise and shock when the storage rack is lowered and stopped are reduced, which greatly contributes to improvement of usability and prevention of damage to the lifting mechanism.

[0010] When the parallel links is gradually compress the shock absorber in contact with the pressing plate, the parallel link and the pressing plate becomes to produce a slight misalignment, the parallel link and the pressing plate between metals Because of the contact, it is easy to slip against displacement and the parallel link does not directly contact the shock absorber, so it is possible to protect the shock absorber, which is generally susceptible to wear and deformation, and to improve durability. it can be a good thing.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 denotes a storage cabinet, which is a door 2 which can be opened and closed on the front side, and pins 5a, 5
A parallel link 6 pivotally supported by b is attached, and front rotating arms 7a facing each other on both sides are integrally connected by a pivot 8 so as to rotate together.

The parallel link 6 includes front and rear rotating arms 7a,
The free ends of 7b are connected by a mounting seat 9 to form a link mechanism.

Numeral 10 denotes a storage rack, which is composed of both side plates 11, a net cage 12 made of a wire connected from the bottom to the back, a net shelf 13 made of the same wire, and a handle 14 attached to the lower front part. Both side plates 11 are fixed to the mounting seat 9 of the parallel link 6.

Here, the articles are stored in a net basket 12 and a net shelf 13, and the handle 14 is used to move the storage rack 10 in and out.

A rear rotating arm 7b is provided inside the base 4.
Plate 15 and torsion spring 16 which are connected to
One end of the torsion spring 16 is a fixing bracket 17 and the other is a receiving pin 1 attached to a rotating plate.
When the storage rack 10 is pulled out and descends, the torsion spring 16 winds up the torsion spring 16 and the reaction force allows the storage rack 10 to be taken in and out with a light operation.

Reference numeral 19 denotes a stopper attached to the upper surface of the base 4, and the stopper 19 is provided at a position where the rear rotating arm 7b of the parallel link 6 is inclined slightly backward from the vertical position.
The storage rack is brought into contact with the storage position stopper at one end and stopped, and the storage rack is in the storage state shown by the two-dot chain line in FIG. At this time, the tip of the rear rotating arm 7b comes into contact with the pull-out position stopper at the other end of the stopper 19 and stops.

FIG. 2 is a detailed view showing a state in which the storage rack 10 is pulled out, lowered and stopped by the stopper 19.
The stopper 19 is formed by bending the metal plate in two directions.
0b, and shock absorbers 21a and 21b made of butyl rubber or the like are bonded and fixed to the upper surface, and a metal pressing plate 2 almost covering the shock absorbers 21a and 21b is further formed on the upper surface.
2a and 22b are bonded and fixed by a method such as in-mold molding.

The shock absorber 21a of the stopper 19
The shape of the pin 5 serving as the rotation axis of the rear rotation arm 7b is
The thickness increases as the distance from a increases.

In the above configuration, the stopper 19 of the lifting / lowering storage device includes the pressing plate 22a, the rear rotating arm 7b for covering the upper surfaces of the shock absorbers 21a, 21b of the stopper 19.
2b, the entire surfaces of the impact plates 21a, 21b are compressed and stopped on the wide surfaces of the pressing plates 22a, 22b, so that the impact absorbing effect is extremely large.

Further, the rear rotating arm 7b is connected to the pressing plate 22.
When the shock absorbers 21a and 21b are compressed in contact with the rear rotating arm 7b and the pressing plates 22a and 22b,
Causes slight displacement, but since the rear rotating arm 7b and the pressing plates 22a and 22b are in contact with each other, the rear rotating arm 7b is easily slipped against the displacement, and the rear rotating arm 7a directly absorbs the shock. Since it does not come into contact with the bodies 21a and 21b, it is possible to protect the shock absorber, which is generally liable to be damaged due to abrasion or deformation, and to form the stopper 19 having excellent durability.

In particular, in this embodiment, as shown in FIG.
The thickness of the shock absorber 21a is increased as the distance from the axis of the rear rotating arm 7b increases. This is because the compression allowance of the shock absorber 21a increases as the distance from the axis increases. This is because the compression ratio at the time when 21a is compressed is substantially uniform at each position, and stable durability can be secured. If the shock absorbers 21a have the same thickness, the compression ratio becomes higher on the side farther from the axis, and there may be a problem such as one side slipping at this portion.

[0023]

As is apparent from the above, according to the present invention, the lifting operation of the storage rack in the lifting storage device is quiet and easy to use, and the durability of the lifting mechanism is excellent in durability and reliability. Can be provided .
