Description

  The present invention relates to a window screen opening / closing device that opens and closes a window screen by rotating an input shaft of an operator main body.

Conventionally, for example, in open / close windows such as a louver window, an awning window, a vertical window, and a horizontal window, a handle with a lock is often attached to the door of a window shoji. Therefore, when operating the handle with lock, in the case of a bay window, the arm must be extended or stretched, and if there is a screen door inside the window shoji, the screen door must be opened. The window shoji could not be opened and closed, which was inconvenient. Further, in the case of the window shoji opening / closing device that opens and closes the window shoji by rotating the manual handle provided on the operator main body, the manual handle has to be rotated a plurality of times, and the opening / closing operability is poor. A window shoji opening / closing device is also known in which an electric motor is directly connected to the input shaft instead of a manual handle and the motor is supported by a bracket (see, for example, Patent Document 1). In addition, as many electric motors as the number of windows to be installed must be prepared, which is not economically obtained. In addition, when the electric motor is configured separately from the bracket, the load is applied to the electric motor when the window shoji is fully opened or closed, and there is a risk that it will be operated from the outside if the operating part is exposed. There were also security concerns.
