Description

[Detailed description of the invention] The present invention is designed to connect a sliding door flush with or close to an adjacent sliding door or a fixed wall in the closed state, so that the sliding door can be connected flush with or close to the sliding door adjacent to it in its closed state. The present invention relates to a sliding door device that is suspended and supported to move in a direction perpendicular to .

Although the above device is a sliding door, it is useful in that it is possible to position the door in a flush state with a beautiful appearance in the closed state. As shown in Publication No. 55-51985, guide grooves are formed not only on the upper side of the sliding door but also on the fixed part on the lower side to ensure smooth opening and closing operations of the sliding door. However, there are disadvantages in that the guide groove located below the sliding door becomes clogged with dirt, making it difficult to clean, and the complicated structure makes manufacturing and assembly difficult. The drawback was that it was not possible to ensure that adjacent sliding doors were kept flush with each other.

The present invention eliminates the need to form a guide groove in the fixed part below the sliding door, and without complicating the structure.
The purpose is to maintain the sliding door closing device stably, to ensure that it remains flush with the adjacent sliding door or fixed wall, and to facilitate the sliding door opening/closing operation.

The feature of the present invention to achieve the above object is that the rail member that suspends and guides the sliding door is provided with a linear guide groove for guiding the hanging tool of the sliding door along the longitudinal direction of the rail member. , which is connected to the linear guide groove at the end and the center of the rail member to form a retracting guide groove for guiding the hanging tool along the width direction of the rail member, and a guide groove for guiding the hanging tool along the width direction of the rail member. A long groove is formed on the end face side along the surface direction of the sliding door, and further, at a lower fixing position opposite to the lower end face of the sliding door at a position corresponding to the lower part of the guide groove for retraction formed in the center part of the rail member, It is pivotally attached to the lower fixed position,
and a swinging member having a guide element on its swinging end side that engages with the long groove, and an urging force that urges the swinging member to maintain its posture in two opposing positions with a dead point in between. a sliding door position changing device comprising a sliding door position changing device, and two positions of the swinging member facing each other across the dead point are a sliding door closing position where the hanging tool of the sliding door is deep in the retracting guide groove. , the hanging device is set in two positions corresponding to the sliding door opening/closing movement position in the linear guide groove, and the posture of the swinging member is configured to be freely switchable between the two positions as the sliding door is opened/closed; , the portion corresponding to the retraction guide groove formed at the end of the rail member is bent so that the center portion thereof enters into the locus of movement of the hanging tool passing through the retraction guide groove formed at the end. A linear or plate-shaped spring is positioned so that the hanging tool that has moved beyond the spring existing position to the back of the retraction guide groove at the end is biased to the back of the retraction guide groove. This configuration provides the following effects.

In other words, as the sliding door opens and closes, the lower end of the lower end of the sliding door, which is located away from the end of the sliding door in the direction of movement that is artificially pushed and pulled, is moved in the front-rear direction of the door. By installing a sliding door position change device, the only guide groove needed to open and close the sliding door by sliding it laterally is to form a linear guide groove or a retracting guide groove on the rail member that suspends and supports the sliding door. Therefore, even if a guide groove is not formed in the fixed part on the lower end side of the sliding door, the lower end of the sliding door is difficult to move in the front-rear direction of the door surface, resulting in the inconvenience that smooth movement is hindered. do not have. Therefore, compared to the conventional structure in which a guide groove is formed in the fixed part on the lower end side to ensure smooth opening and closing operation of the sliding door, the guide groove formed in the fixed part on the lower end side is more likely to be clogged with dirt. There are no drawbacks such as making it difficult to clean or complicating the manufacturing process and assembly work as a sliding door device.

In the closed state, one end of both ends of the sliding door in the moving direction stably positions the sliding door toward the back of the retracting guide groove by a biasing action on one side of the dead point of the sliding door position changing device; This is one of the features of this type of sliding door device because the other end is stably positioned toward the back of another retraction guide groove by the biasing action of the spring. The closed position of the sliding door surface can be stably maintained so that it is flush with the adjacent sliding door or fixed wall.
