Description

[Detailed description of the invention] [Industrial field of application] The invention is such that the horizontally rotating opening/closing door of the cabinet is pushed in along the outer surface of the side plate of the cabinet body from the 90-degree open state. It is related to the device.

[Conventional technology]

As a storage device for an opening/closing door of this type, Japanese Utility Model Publication No. 33-13403 as a prior art discloses that a vertically longitudinal guide body is provided along the outer surface of the side plate of the cabinet body so as to be movable back and forth, and the front end of the guide body By pivoting the opening/closing door so that it can rotate horizontally, when the opening/closing door is opened 90 degrees, the opening/closing door can be pushed in along the outer surface of the side plate of the cabinet main body, and can be accommodated. Two vertically elongated interlocking rods are vertically slidably pivoted adjacent to each other in the vertical direction, and the interlocking rod located closer to the front end of the guide body and the side plate of the cabinet body are connected to each other. The interlocking rod located near the front end and the rear end of the guide body and the rear end of the side plate of the cabinet body are connected by a pair of upper and lower equal-length link mechanisms, thereby facilitating the storage operation of the opening/closing door. A device that does this has been disclosed.

[The problem that the idea aims to solve]

However, in this prior art, two interlocking rods are attached to the guide body, and each of these two interlocking rods is connected to the side plate of the cabinet body using two equal-length links, upper and lower. However, the manufacturing cost increases due to the large number of parts, and furthermore, when the guide body is moved to the front side of the cabinet body and the door is closed, the link connected to the rear end of the side plate of the cabinet body is exposed to the outside. Therefore, there was a problem that the appearance when the door was closed deteriorated.

In addition, in this prior art, the side plate of the cabinet body and each interlocking rod are only connected by two parallel links, so when the guide body moves back and forth, the interlocking rods may rub against the guide body. However, the guide body has to slide up and down, which increases the sliding resistance of the interlocking rod, making it difficult to move the guide body back and forth, and also increasing the squeak noise.

Furthermore, in this prior art, since the interlocking rod is mounted at a position approximately midway between the front and rear of the guide body, there is a problem in that the guide body is likely to be distorted when the guide body is pushed into the guide body.

In other words, the opening/closing door is pivotally attached to the front end of the guide, and when the guide is pulled out toward the front of the cabinet, the guide is pulled from its front end, so the guide is narrow. Even if
It can be pulled out smoothly, but when pushing in the guide, you have to push the front and back of the guide with the rear end of the opening/closing door. Due to the fact that the link does not hold the guide body parallel to the side plate of the cabinet body, the rear end of the guide body swings from side to side when the guide body is pushed into the back of the cabinet body. hand,
It was easy to get strained.

The present invention aims to solve these problems.

[Means to solve the problem]

In order to achieve this objective, the present invention provides a guide body made of a thin metal plate along the outer surface of the side plate of the front-open cabinet body so as to be movable back and forth in the depth direction of the cabinet body, and at the front end of the guide body. , in a cabinet in which a base end of an opening/closing door is pivotally connected to the cabinet main body so as to be horizontally rotatable, a reinforcing slat piece protruding toward a side plate of the cabinet main body is provided on a rear end edge of the guide body; The guide body is bent over approximately the entire length thereof, and a vertically elongated bracket is provided at a portion of the inner surface of the guide body where the stile is off-centered, and one side of the bracket is connected to the slant piece of the guide body. A longitudinal groove is formed between the two, and a longitudinal interlocking rod is vertically slidably inserted into the longitudinal groove, and the interlocking rod and the front end of the side plate of the cabinet body are connected by a pair of upper and lower links of equal length to form a parallel link mechanism, and the intermediate portions of each link are connected to the bracket by an auxiliary link.

[Functions and effects of the idea]

With this configuration, when the opening/closing door is opened 90 degrees and stored on the side of the cabinet body,
The pair of upper and lower links and the auxiliary link are covered by the guide body and the opening/closing door. However, when the guide body is moved toward the front of the cabinet body and the opening/closing door is closed, both the upper and lower links and the auxiliary link are covered. Both are covered by the guide body, and in any case, there is no deterioration in appearance due to the link and the auxiliary link being exposed to the outside.

In addition, since the upper and lower links and the guide body are connected by auxiliary links, when the guide body moves back and forth, the links are moved up and down by the auxiliary links, and the interlocking rod rubs against the guide body. Since this phenomenon is reduced, the resistance and squeak when the interlocking rod slides up and down can be reduced.

Furthermore, since the interlocking rod is attached to the rear end of the guide body and the interlocking rod and the side plate of the cabinet body are connected by a link, the gap between the rear end of the guide body and the side plate of the cabinet body is reduced. The spacing is kept constant, and when pushing the guide toward the back of the cabinet body, the phenomenon in which the rear end of the guide swings in the left-right direction of the cabinet body is prevented. This makes it possible to prevent twisting caused by swinging, and this, combined with the ability to reduce the resistance when the interlocking rod slides up and down, makes it possible to reduce the amount of resistance caused by the vertical sliding of the interlocking rod, even though only one interlocking rod is provided. ,
The operation of moving the guide body back and forth, in other words, the operation of storing and pulling out the opening/closing door can be performed with light force.

The interlocking rod is attached to a vertical groove between a reinforcing stile bent at the rear end of the guide and a bracket fixed to the inner surface of the guide. The piece is also used as the attachment member for the interlocking rod, and the bracket for attaching the interlocking rod is also used as the member for attaching the auxiliary link. This, combined with the fact that only one interlocking rod is required, greatly simplifies the overall structure of the storage device compared to the prior art, and reduces manufacturing costs. This will result in a significant reduction.

Therefore, according to the present invention, it is possible to manufacture at low cost a storage device for an opening/closing door that allows storing and pulling out the opening/closing door to be performed with light force and quietly, and prevents deterioration of the appearance. have

At the front ends of both guide bodies 5, there is a double door opening/closing door 17 for the front opening of the cabinet body 1.
If the base ends of the door 17 are pivoted horizontally through a pair of upper and lower hinges 18, and the opening/closing door 17 is opened 90 degrees,
The cabinet body 1 can be freely stored along the outer surfaces of both left and right side plates 2.

Then, on the rear end edge of the guide body 5, a reinforcing stile 5a extending toward the side plate 2 of the cabinet body is bent over the entire length of the guide body 5. A hollow bracket 27 having a rectangular cross section and elongated in the vertical direction is provided at a portion near the stile 5a.
A longitudinal groove 19 extending in the vertical direction is formed between one side surface 27a of the 7 and the stile piece 5a, and a longitudinal interlocking rod 20 is installed in the longitudinal groove 19. 2 of the same length are inserted into the interlocking rod 20 and the front end portion of the side plate 2 in the cabinet body 2.
The book links 21 are arranged in parallel, and one end and the other end of both links 21 are connected to the cabinet 1, respectively.
Pins 22 and 23 are attached to the side plate 2 and the interlocking rod 20 in
