Claims

[Scope of utility model registration request]

(1) A window opening/closing body whose one side edge is rotatably supported at the opening end of a window formed on a wall, and one end of which is rotatably supported by the inner surface of the window opening/closing body and whose other end is rotatably supported. The first formed at the free end
a second opening/closing arm having one end rotatably supported on the opposite opening/closing body support side of the wall surface and the other end rotatably connected to the first opening/closing arm; A window opening/closing device comprising: a stopper device that restricts mutual rotation of the first and second opening/closing arms when the window opening/closing body is closed and opened at a predetermined angle.

(2) The stopper device is a lock provided at the free end of the first opening/closing arm when the window opening/closing body is closed or opened at a predetermined angle and the first and second opening/closing arms are in a bent relationship. When the opening/closing arm is selectively locked in a plurality of locking grooves formed in a stopper receiver fixed to the wall side, and the first and second opening/closing arms are in a linearly extending relationship. The window opening/closing device according to claim 1, wherein the locking pin is inserted into a locking hole formed in the overlapped portion of the window opening/closing device.

(3) The window opening/closing device according to claim 1 or 2, characterized in that an operating handle is provided at the free end of the first opening/closing arm.

(4) The locking part provided at the free end of the first opening/closing arm is
It is a locking pin provided on a slide body that is slidably assembled to an operating handle provided at the free end, and the plurality of locking grooves formed in the stopper receiver are locking holes into which the locking pins are inserted. A window opening/closing device according to claim 2 or 3, wherein the sliding body is always elastically biased in a direction in which the locking pin is inserted into the locking hole.
