Claims

[Claims for Utility Model Registration] A winding drum to which the wires of a window are connected between a window frame such as a smoke evacuation window and a shoji that is biased in the window opening direction, and the winding drum is connected to the box body. A handle supported inside the box body and exposed on the front side of the box body is rotated in one direction to rotationally drive the winding drum to wind up the wire and close the window, and the rotational operating force of the handle is By releasing the lock, the rotation of the winding drum in the unwinding direction is locked to maintain the closed window state, and by the operation of releasing the lock of the winding drum, the winding drum is biased in the window opening direction. In the window opening/closing handle box, which opens the window by letting out the wire while rotating the drum, the handle box is provided with a rotating shaft integrally formed on the box body and protruding into the box body. , supports the rotary shaft so that it can freely rotate around the axis and move in the axial direction, and is biased and supported in a protruding direction away from the front of the box body, and interlocks with the rotary shaft and the winding drum. The drive body is rotatably supported by the box body, and is connected to the drive body so as to be able to rotate integrally with the drive body when the handle is moved in the protruding direction, and the connection is released when the handle is moved in the opposite direction. a storage groove that is aligned with the handle is formed in the front face of the box main body, a fixed engaging body is protruded from one of the storage groove and the handle, and the other side is
A movable engaging body that holds the handle housed in the storage groove by engaging with the fixed engaging body is attached, and the movable engaging body is moved to remove the movable engaging body from the fixed engaging piece by a release operation. A handle box for opening/closing a window, characterized in that the handle is removed from the storage groove as the handle is biased in the projecting direction.
