Description

[Detailed Description of the Invention] The present invention has a pair of sliding doors connected flush with or close to the sliding door or a fixed wall located between them in the closed state, and facing forward in the open state. The present invention relates to a sliding door device supported to move in a direction perpendicular to the door face between a fully closed position and a position just before fully closed.

Such a sliding door device is normally used by opening a pair of sliding doors one side at a time; for example, when one sliding door is fully opened or partially opened, the other sliding door may also be opened. , a pair of sliding doors may both be operated to the open side. To open a sliding door, it is usually done by supporting the handle or by supporting the closing end of the sliding door, but depending on the user,
This may be done by supporting the closing end of the sliding door and the opening end of the sliding door at the same time, or by supporting only the opening end of the sliding door. When the sliding door is operated, there is a risk that the fingers supporting the opening side end of the sliding door may be caught between the opposing ends of the pair of sliding doors, and there is room for improvement.

The present invention has been developed with the above-mentioned circumstances in mind, and its purpose is to provide a sliding door device that can be easily modified to improve the appearance of the sliding door without impairing the advantages of the sliding door device. The point is to avoid the risk of being caught.

The characteristic configuration of the sliding door device according to the present invention is that, in order to separate the opposing ends of the pair of sliding doors by a predetermined distance when both of the sliding doors are operated to the open side, a stopper is provided to restrict the movement range of the sliding doors toward the approach side. It is attached to the top or bottom end of the sliding door.

Next, the effects of the characteristic configuration of the present invention will be described.

In other words, even if a pair of sliding doors are both operated to the open side by the action of the stopper,
To ensure that there is a gap between opposing ends of a pair of sliding doors that allows the presence of fingers, and furthermore, the stopper is located on the upper end surface or the lower end surface of the sliding door, so that the stopper is in the closed state of the sliding door. It is made so that it is difficult for the user to see.

Therefore, even if other sliding doors are being operated to the opening side when the sliding door is pulled by supporting the opening side end of the sliding door, there is no danger of fingers being caught between the sliding doors. In this way, the sliding door can be opened safely, and the stopper provided for this purpose can suppress the damage to the appearance of the sliding door, thereby fully utilizing the advantages of the sliding door device, which can be closed with a beautiful appearance. As a result, we have achieved a sliding door device that can be used even better overall.
