The opening/closing device 16 formed in this manner has a screw thread 24 attached to the outdoor end of the right wall plate 17D of the container body 17 on the indoor side in the middle of the mullion 9 vertically installed in the window frame body. The opening/closing device 16 is integrally attached to the vertical axis 9, and the opening/closing device 16 is attached so as to be rotatable within a predetermined angular range α around the shaft pin 24A of the hinge 24.
In addition, the screen door mounting piece 9M of the mullion 9 has an opening/closing device 16.
The notch hole 9P is opened over a range into which the protruding member 22 can be inserted and allows rotation of the protruding member 22 when the opening/closing device 16 rotates. The protruding member 2 is inserted into the notch hole 9P opened in this way.
2 is inserted, and the tip of the protruding member 22 is connected to the vertical stile 14A on the rotating end side of the hinged door 14 via the hinge 25, so that the hinged door 14 is connected to the protruding member 2.
The opening/closing operation is performed over a predetermined angular range β by the forward/backward movement of the device 2 and the rotation of the container body 17. The casement window S equipped with the opening/closing device 16 in this way has the window opening frame 3
It is integrally installed on the outdoor side of the

In addition, in the figure, 26 is a screen door attached to the indoor side of the opening/closing part S _B.

Next, the operation and effects of this embodiment configured as described above will be explained.

Now, the opening/closing device 16 of this example has a hinged door 14 attached to the window frame body.
The opening/closing device 16 is pivotally connected via a hinge 15 so as to be rotatable in a single-opening manner, and is interposed between the window frame body and the hinged door 14. The main body is a protruding member 22 that is supported through the front and rear walls 17A and 17B so as to be movable and retractable. The tip of the protruding member 22 is pivotally attached to the vertical stile 14A on the rotating end side of the hinged door 14 via a hinge 25, and the container body 17 is attached to the mullion 9 of the window frame body.
It is pivotally connected via a hinge 24 to the main body. Therefore, as shown in FIGS. 2 and 7, when the casement window S is a tall window and the casement door 14 is opened or closed, the chain 20 attached to the chain wheel 19 attached to the worm 18 is moved downward. When the opening operation is performed, the protruding member 22 is moved forward by the worm 18 and the worm gear 21 in the direction of the solid arrow. As this protruding member 22 moves forward, the hinged door 1
4 is rotated toward the outdoors around the hinge 15, and at the same time, the container body 17 is rotated around the hinge 24 in the direction of the solid line arrow. Furthermore, when the ring chain 20 is opened and the protruding member 22 is extended by a predetermined length, the container body 17 is rotated within a predetermined angular range α and reaches a position perpendicular to the plane of the opening/closing part S _B. The hinged door 14 is opened at a predetermined opening angle β. In addition, when closing the opening/closing part S _B , by reversing the above ring chain operation, the protruding member 22 is retreated in the direction of the double-dot chain arrow, and the container body 17 is rotated in the direction of the double-dot chain arrow. The hinged door 14 can then close the opening/closing part _SB . In this way, the container body 17 of the opening/closing device 16 is pivotally attached 2 to the window frame body.
4. Furthermore, since the tip of the protruding member 22 is pivotally attached 25 to the rotating end side of the hinged door 14 which is pivoted 15 to the protruding frame, the opening and closing operation of the hinged door 14 can be performed extremely smoothly. Since the protruding member 22 is accommodated in the container body 17 which is pivotally attached 24 to the window frame body and expands and contracts, the load of the container body 17 and the moment applied during operation are applied to the pivot member 24, so that the protruding member 22 is expanded and contracted. Since no external force is applied to the protruding member 22, troubles due to distortion of the protruding member 22 can be prevented. In particular, there is no need to use an elastic material to avoid distortion, so the opening/closing device 16 has excellent long-term durability. Obtainable. Also,
The above configuration has many features such as being suitable for remote control.

The present invention is a casement window opening/closing device in which a hinged door is rotatably attached to a frame body in a single-sided manner, and is interposed between the frame body and the hinged door. The main body is a protruding member that is supported through the container so that it can move forward and backward, and a gear that moves the projecting member back and forth and a worm that rotates the gear are housed in the container, and the tip of the projecting member is connected to the casement window. A chain wheel is provided on the rotating end side of the vessel body, one end side of the container body is rotatably pivotally connected to the frame body, and the chain wheel is provided on the rotating end side of the vessel body for rotating the worm. When the gear is rotated, the body is rotated about its pivot point by the forward and backward movement of the protruding member, and the hinged door is opened and closed. In addition to being able to have a compact structure, the protruding member is housed in a body that is pivotally connected to the window frame body and moves forward and backward, so the load of the body and the moment applied during operation are applied to this pivot part. Therefore, since no external force is applied to the protruding member, troubles due to distortion of the protruding member can be prevented and the opening/closing operation of the hinged door can be performed smoothly. Since there is no need to use any members, it has excellent long-term durability and is suitable for remote control.
