Description

[Detailed explanation of the invention] [Field of industrial application] This invention consists of a fixed shoji and a movable shoji arranged in the same plane in a frame, and a state in which the movable shoji moves in parallel toward the indoor side. The present invention relates to a guide device for a movable shoji, which is a sash that is opened and closed in the sliding direction, and is adapted to this sash.

[Conventional technology]

This type of sash is disclosed, for example, in Japanese Patent Laid-Open No. 57-209377. The guide device for guiding the parallel movement of the movable shoji described in the publication consists of a lock lever receiver provided on the frame and a lock lever provided on the movable shoji, and the guide device for guiding the parallel movement of the movable shoji is made up of a lock lever receiver provided on the frame and a lock lever provided on the movable shoji. The movable shoji can be moved toward the indoor side parallel to the rails, and when opening in a direction overlapping the fixed shoji, that is, in a sliding manner, the lock lever release button is pressed to remove the lock lever from the lock lever receiver.

[Problem that the invention attempts to solve]

By the way, when closing a movable shoji in the sliding direction, if the shoji happens to be closed forcefully, stress will be applied to the shoji to open it slightly due to the reaction, but with the conventional guide device, the lock lever will close at the same time. Since it engages with the lock lever receiver, unreasonable force is applied to the lock lever and the lock lever receiver, and there is a high risk of damage. Furthermore, when opening in the sliding direction, it takes time and effort to press the lock lever release button each time and remove the lock lever from the lock lever receiver. On the other hand, without the conventional guide mentioned above,
Due to the reaction, the shoji opened in the sliding direction and at the same time moved toward the fixed shoji, causing a problem of collision with the fixed shoji.

The aim of this idea is to solve the above-mentioned problems.It is possible to stably move the movable shoji when it is moved parallel to the indoor side, and also to prevent the reaction even if it receives reaction when the movable shoji is closed by sliding. To provide a movable sliding sash guide device for sliding sashes, which allows the movable sash to move toward the fixed sash and prevents the movable sash from moving toward the fixed sash, and provides reliable function over a long period of time.

[Means for solving problems]

The gist of this solution is that when moving the movable shoji indoors or returning to its original position, a guide member protruding from the movable shoji is guided by a regulating plate provided on the lower frame of the frame. When the movable shoji moves toward the indoor side and slides toward the open side, the handle of the movable shoji is controlled by a locking lever provided in the movable shoji that interlocks with the handle. Furthermore, when the movable shoji is closed at a shifted position and the guide plate faces the regulation plate, the lock lever is removed from the operating rod and the movable shoji is closed. It is constructed with a lock device that allows the handle to be operated.

[Effect]

When the movable shoji moves from the closed state in parallel with the fixed shoji to the indoor side, the guide member moves in parallel while being guided by the regulating plate, and when the movable shoji is opened in parallel, the starting At this time, the outdoor side end surface of the guide member comes into contact with the indoor side end surface of the regulating plate, and the lock lever is engaged with the operating rod to disable the handle operation, and the movable shoji is opened while maintaining the shifted state. Conversely, even if the movable shoji slides forcefully in the closing direction and collides with the doorstop, and the movable shoji opens slightly due to the reaction, the outdoor end surface of the guide member contacts the indoor end surface of the regulating plate, and at the same time the lock lever is locked to the operating rod, making it impossible to operate the handle, allowing for reaction but preventing the movable shoji from returning to the fixed shoji side.
