When the vertical stile 3 is pushed inward, it engages with the guide rod 42, and in both engaged states, the foot portions 45A, 45A' of the interlocking body 45,
and the foot portion 43B of the operation camera 43 are configured to engage with each other, so that the interlocking body 45 moves up and down in conjunction with the vertical movement of the operation camera 43 in the direction of the guide rod 42, and the locking means 25 is guided along a rail member 32 provided on the lower frame 9, and the locking portion 45C is connected to the neck of the vertical movement element 28 of the locking means 25 in a connected state around its axis. This is what I did.

[Effect]

In the present invention, when the locking means is moved up and down to engage and disengage, the operating head of the operating device is provided to protrude from the interior surface of the stile. Therefore, the operation can be performed on the indoor surface without touching the locking means. As a result, unlike the conventional example, there is no danger of the shoji being blown by the wind and fingers getting caught between the shoji and the window frame.

In addition, in order to transmit the motion of the operation camera to the locking means, the camera is moved up and down along the guide rod,
Furthermore, since the interlocking body that interlocks with this is also moved up and down along the guide rod, photographing and movement of the interlocking body are extremely smooth.

Furthermore, since the guide rod is provided inside the vertical stile to effectively utilize space, the movement mechanism is not exposed to the outside, resulting in an excellent appearance.

Moreover, the operating lever, the interlocking body, and the actuator are separate bodies, and the foot of the operating lever penetrates the indoor surface of the vertical stile and engages with the guide rod by pushing from the indoor side to the indoor side, The foot of the interlocking body also engages with the guide rod by pushing inward into the vertical frame, and in both engaged states, the foot of the interlocking body and the foot of the operation camera engage with each other, and the foot of the operation camera engages with the foot of the operation camera. Since the interlocking body is configured to move up and down in conjunction with the vertical movement of the guide rod, the operation camera and the interlocking body can be retrofitted, and the assembly workability is extremely high. Furthermore, the interlocking mechanism can be disposed within a small space, and the cross-sectional area of the vertical stile can be small.

On the other hand, the present invention is directed to a casement window. Therefore, if the locking means and the interlocking body are rigidly connected, the rigid connecting means will be damaged when the door is opened. However, since the locking portion is loosely fitted around the axis of the neck of the vertical movement element of the locking means, it is possible to slide the locking portion open.

〔Example〕

The present invention will be explained in more detail below with reference to embodiments shown in the drawings.

First, the entire casement window will be explained with reference to FIGS. 4 and 5.
Shoji 6 with glass 5 fitted inside 2, 3, 4
is housed within the window frame 7, and when moving from closing to opening, the shoji 6 slides open while moving its axis (toward the right in the illustrated example). window frame 7

Since the shoji 6 is restricted by the connecting arm 24, the left side of the shoji 6 slides to the right. At this time,
The door roller 30 slides along the rail member 32. At the same time, as the shoji 6 is pushed open, the mounting body 26 and the rotating shaft 27 also rotate toward the outside.
However, since the actuator 28 is loosely fitted to the rotating shaft 27 and the lock plate 29 is engaged with a support shaft 33 attached to a holder 31 that is regulated by a rail member 32, the actuator 28 does not rotate.

Eventually, when the desired degree of opening of the shoji 6 is reached, the actuator 28 is pushed down, and the lock plate 29 is pushed down accordingly.
When the lower end thereof is fitted into and engaged with the corresponding engagement receiving hole 34, the locking means 25 is fixed in position, so that the shoji 6 is also fixed in position and maintained in its open state. If it is desired to release the lock, all that is required is to lift the actuator 28, and then the shoji 6 can be opened and closed freely again. The illustrated example has a maximum opening degree of 90 degrees, and a stopper 35 is provided on one side edge of the lock plate 29 to determine the maximum opening degree. Note that the locking ball 39 is connected to the spring 38.
Since the narrowed portions 36A, 3 are pressed by
Engagement and disengagement from 6B is performed smoothly.

In order to operate the locking means 25, the following operating device is installed.
