Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door structure in which a deadbolt protrudes and locks when a trigger is operated.

Buildings such as collective housing and commercial facilities have traditionally adopted a sliding door structure in which the door slides within a frame provided at the edge of the opening and is locked by providing a key at the contact point between the door tip and the vertical frame. rice field. As for the type of key, a sickle-shaped tip (hereinafter also referred to as "dead bolt") rotated by the rotation of the lock bolt provided on the door side is provided on the frame and is a receiving seat (hereinafter also referred to as "strike"). ) had something to hook on. However, depending on the type of building and the purpose of each room, it was sometimes difficult to manually lock the doors, or the doors were sometimes forgotten to be locked.

In view of such circumstances, a structure of a key that automatically locks the door when it comes into contact with the frame has been disclosed (see, for example, Patent Document 1). In detail, a trigger that transmits power to the bolt of the lock is provided, and by dividing the trigger into contact with the frame and pushing it into the door in two steps, the deadbolt rotates step by step and protrudes from the door. Therefore, collision with the frame is avoided, and the door is locked at the desired timing.

However, Japanese Patent Laid-Open No. 2002-100000 cannot counteract unintentional deadbolt protrusion. In other words, if the trigger is fully pushed in before the door closes, the deadbolt will protrude, not only inevitably colliding with the frame, but there is also the risk of the user being caught in the deadbolt and injured. be. In addition, since there is a possibility that the trigger may be pressed unexpectedly by means other than contact with the frame, locking safety is lacking.

The inventors have arrived at the conclusion that a structure in which the trigger cannot be easily pressed is suitable for avoiding the user's unexpected pressing of the trigger due to the structure of the sliding door. That is, the trigger should be prevented from being subjected to an external force other than the frame, and the deadbolt should protrude and fit into the strike as long as the pressure from the frame is applied. Also, in order to adopt such a structure, it should be possible to easily add it without removing the conventional sliding door structure. In addition, from the viewpoint of improving safety, the deadbolt should not be visible through the gap between the door tip and the frame.

SUMMARY OF THE INVENTION Accordingly, it is a first object of the present invention to provide a sliding door structure that avoids accidental pressing of a trigger and can be reliably locked regardless of whether the door is opened or closed by a user. A second object of the present invention is to provide a sliding door structure that is highly compatible with conventional sliding doors and vertical frames. A third object of the present invention is to provide a sliding door structure that resists unauthorized unlocking and enhances safety after locking.

That is, the present invention is a sliding door structure for locking a door tip portion corresponding to an end face of a sliding door body and a vertical frame, wherein the sliding door body includes a trigger protruding from the door tip portion in an open state and a closing door. a deadbolt that protrudes from the door tip portion and locks the vertical frame in a closed state; It has a hollow strike for hooking a deadbolt, and has a convex portion narrower than the inner width of the barrier so as to press the trigger in the closed state.

Further, the barrier portion has a thickness substantially equal to that of the sliding door body, and is attached to the door tip portion so that the outer side is flush with the side surface of the sliding door body. and the barrier channel material has a through hole for inserting the trigger and the deadbolt.

The barrier portion protrudes to a position substantially equal to the tip portion of the trigger, the convex portion protrudes from the vertical frame by a length substantially equal to that of the barrier portion, and the vertical frame is It is desirable to have a pair of vertical frame wall portions arranged so as to sandwich both sides of the barrier portion in the closed state.

Moreover, it is preferable that the vertical frame further includes cushioning portions provided on both sides of the convex portion so as to be in contact with tip portions of the side portions of the barrier in a closed state.

Moreover, it is desirable that the strike has a reinforcing portion on the back surface of the portion that contacts the trigger in the closed state.

According to the sliding door structure of the present invention, it is possible to avoid unexpected pressing of the trigger regardless of the situation such as the traffic of users and the opening/closing of the door, and to achieve reliable locking.
