Description

[Technical field] The present invention relates to a mounting structure for a winding door that can be smoothly opened and closed by preventing finger jamming.

[Background Art] Conventionally, as shown in FIG. 8, a winding door 3 is slidably inserted into a guide groove 11 extending from a front portion of the storage body 1 to an upper portion thereof and then to a rear portion thereof so that the front opening 2 of the storage body 1 is opened. Although a storage body 1 that is designed to be opened and closed has been proposed, the opening and closing of the winding door 3 is performed by simply utilizing the dead weight of the winding door 3, and although the structure is certainly simple, the winding door 3 is closed. Sometimes I stuff my fingers
In addition, when the door is opened, the winding door 3 is pulled up too much, the impact upon opening and closing is great, smooth opening and closing cannot be performed, and noise is generated. In addition, a means for locking the housing 3 with the winding door 3 opened and closed is also required.

[Purpose of Invention] The present invention has been made in view of the above circumstances. The purpose of the present invention is to smoothly open and close the winding door by utilizing the weight of the winding door, and to provide a housing for the winding door. It is an object of the present invention to provide a structure for attaching a winding door, which does not require the locking means.

DISCLOSURE OF THE INVENTION In the winding door mounting structure of the present invention, the winding door 3 that opens and closes the front opening of the housing 1 is slidably mounted from the front part to the upper part of the housing 1, and then to the rear part. A hollow body balancer 5 having a spiral spring 4 housed therein is rotatably attached to the rear portion of the container 1 at a substantially central position in the height direction of the container 1, and the spiral derived from the balancer 5 is rotated. One end of the spring 4 is connected to the winding door 3, and the above object is achieved by this configuration. That is, when closing the winding door 3, the spiral spring 4 of the balancer 5 supports the own weight of the winding door 3 and
When the winding door 3 is opened, the weight of the winding door 3 is balanced when the connecting portion of the winding door 3 with the spiral spring 4 is close to the winding door 3. When the door 3 is further opened, the balancer 5 is reversed and the falling speed of the winding door 3 is regulated by the spiral spring 4 so that the door 3 can be smoothly fully opened.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

The storage body 1 is box-shaped and has front and bottom surfaces opened, and is arranged along a wall surface of a kitchen or the like. The inside of the storage body 1 is divided into left and right by a partition plate 7, and three shelf plates 8 are attached to the left and right storage spaces, respectively.
The front ends of the partition plate 7 and the shelf plate 8 are set to be less than the front ends of the side plates 9 of the storage body 1, and a space is provided between the uppermost shelf plate 8 and the top plate 10 of the storage body 1 for storage. A guide groove 11 is formed from the front part of the body 1 to the upper part and then the rear part. The winding door 3 is formed by rotatably connecting a plurality of slats, and is slidably inserted into the guide groove 11 to open and close the front opening 2 of the storage body 1. . On the back plate 6 of the storage body 1, a vertical bar 1 is provided at a substantially central portion of the outer surface thereof.
2 is attached, and the balancer 5 is rotatably attached to the side surface of the vertical bar 12 via a fixing metal fitting 13 at a substantially central portion. The balancer 5 is a hollow body, the spiral spring 4 is housed inside, and one end of the spiral spring 4 is led out from a lead-out hole 14 thereof. One end of the spiral spring 4 is substantially the rear end of the winding door 3. It is connected to the central part.

Thus, when the winding door 3 is closed, the self-weight of the winding door 3 is supported by the biasing force of the spiral spring as shown in FIGS. Is regulated. Also, when the closed winding door 3 is opened, as shown in FIGS. 6 (b) and 7 (b), the rear end of the winding door 3 is close to the balancer 5, as shown in FIGS. Weight is balanced. When the winding door 3 is further pulled up, the balancer 5 is reversed as shown in FIG. 6 (c) and FIG. 7 (c), and the falling speed of the winding door 3 is regulated by the urging force of the spiral spring 4 to smoothly fully open. It is possible and does not generate impact noise. In this way, the dead weight of the winding door 3 is determined by the spiral spring 4
Since it is supported by, it is not necessary to lock the winding door 3 to the storage body 1 at the time of opening and closing, and a separate locking means is not required.

[Advantage of the Invention] According to the present invention, the winding door for opening and closing the front opening of the storage body is slidably attached from the front part to the upper part and then to the rear part of the storage part, and at the rear part of the storage part. A hollow body balancer having a spiral spring housed therein is rotatably mounted at a substantially central position in the height direction of the storage body, and one end of the spiral spring derived from the balancer is connected to the winding door. Therefore, when closing the winding door, the biasing force of the spiral spring derived from the balancer can support the weight of the winding door to control the falling speed of the winding door and prevent finger jamming, etc. The weight of the winding door is balanced when the door is close to the spiral spring, and the balancer is inverted when the winding door is opened further, and the falling speed of the winding door is regulated by the spiral spring. It can be fully opened in a mood, and it does not generate impact noise,
Further, since the weight of the winding door is thus supported by the spiral spring, it is not necessary to lock the winding door to the storage body in the opened / closed state, and a separate locking means is not required.
