Description

[Detailed description of the invention] [Field of industrial application] This invention involves fitting an outer shoji and an inner shoji into a window frame, and pulling the inner and outer shoji together using a locking device provided on the joining frame of the inner shoji. This invention relates to a shoji fixing device for sliding windows.

[Conventional technology]

Conventionally, to secure the inner and outer shoji of a sliding window, a locking device called a crescent lock was installed on one side of the inner and outer sliding stile, and this locking device was used to lock the other of the inner and outer sills. By moving them together, the inner and outer frames were fixed at the midpoint in the vertical direction.

Conventionally, as shown in Japanese Utility Model Publication No. 51-51748, a locking device is provided on the outer frame of the outer shoji, and upper and lower fixing members housed in the upper and lower ends of the outer frame are provided with a locking device. An operating mechanism interlocked with the locking device is connected, and the operating mechanism is housed within the outer frame;
When the locking device is locked, the upper and lower cams provided on the upper and lower fixing members are rotated via the operating mechanism, and these cams are pressed from the inside only against the top of the window frame and the bottom rail, thereby locking the top of the outside window frame. The inner and outer shoji are secured by pulling the lower ends inward, fixing these ends to the upper and lower rails, and then using the locking device to draw the inner and outer frames to the outer frames. Some were designed to be fixed to .

[Problem that the invention attempts to solve]

However, if only a locking device such as the above-mentioned crescent lock is used to pull the inner and outer sashes together, the inner and outer sills will become unstable in their positions in the inner and outer directions relative to the window frame when locked. , it is difficult to properly apply the pressure contact force of the sealing material that is interposed between the inner surface of the outer shoji frame and the outer surface of the window frame, and is held on one side and pressed against the other. There have been problems in that if the sealing material becomes too large, the sealing material becomes easily damaged, or conversely, the pressure contact force disappears or becomes too small, making it impossible to obtain sufficient airtightness or watertightness by the sealing material.

In addition, when locking, the conventional method of pulling the upper and lower ends of the outer stile inward and fixing it to the top of the window frame and the lower outer rail, The sealing material is strongly compressed and easily ages, and when the locking device is locked, the inner side stile is pulled towards the outer side, causing the inner shoji to move outward, causing damage to the inner side of the stile and the window frame. There has been a problem in that the sealing, that is, the airtightness and watertightness of the sealing material interposed between the outer surface and the outer surface of the container, tends to be uncertain.

This invention solves the above-mentioned problems, and when the locking device is locked, the sealing material interposed between the inner and outer stile and between the inside of the stile of the inner shoji and the outside of the window frame is To provide a shoji fixing device for a sliding window which presses against a mating member with pressure contact force, prevents the sealing material from being damaged or aged, and ensures reliable and stable sealing with the sealing material. This is the purpose.

[Means for solving problems]

With this idea, the shoji fixing device for sliding windows is installed on the window frame at the top and bottom ends of the inner stile of the inner shoji and presses the top and bottom rails equally from both the inside and outside sides to fix the top and bottom. These fixing members are connected to an actuating mechanism that interlocks with the locking device, and the actuating mechanism is housed in the inner fitting stile, and when the locking device is locked, the upper and lower fixing members are connected to the upper and lower inner sections. The upper and lower ends of the inner stile are fixed to the upper and lower inner rails at the inner and outer positions when unlocked, and the upper and lower ends of the inner frame are fixed to the upper and lower inner rails when unlocked.
The lower fixing member releases the upper and lower rails.

[Effect]

The shoji fixing device for sliding windows based on this invention has the upper and lower fixing members installed on the inner stile when the locking device is locked. By pressing, the upper and lower ends of the inner sliding stile can be fixed to the upper and lower inner rails in the same position as they are when unlocked. The sealing material interposed therebetween can be maintained at the same appropriate pressure contact force when the lock is locked as when the lock is unlocked. In addition, even if the outer stile is pulled toward the inner stile due to the locking device, the inner shoji is in the same position in the lateral direction as when the lock is unlocked. A large force is not applied to the sealing material interposed between the inner surface of the stile and the outer surface of the window frame, and the sealing material is securely and stably sealed without applying excessive force to the sealing material. can.
