Description

The present invention includes a fully closed state in which the entire opening of the window frame is closed by a window screen, an inward state in which the window screen rotates inwardly about the horizontal axis of the lower frame of the window frame, and the left and right sides of the window frame. Drive control that performs opening / closing start operation and position holding operation of window shoji in an open / close state selection type window structure that can selectively open the window shoji in the indoor side around the vertical axis of one side frame The present invention relates to a handle device used as an input means for a mechanism.

The window structure of a building is centered on a sliding-open type window structure in which the window shoji moves linearly within the window frame opening along the rails of the upper and lower frame parts of the window frame, or on the hinges of the left and right frame parts of the window frame. There is an open / close state selection type window structure as a different type from the rotary opening type window structure in which the window shoji rotates.

This open / closed state selection type window structure includes a fully closed state in which the entire opening of the window frame is closed by a window screen, and an inward state in which the window screen is rotated indoors around the horizontal axis of the lower frame portion of the window frame. It is possible to selectively select an inwardly open state in which the window shoji is rotated indoors around the vertical axis of the left and right side frame portions of the window frame (Patent Documents 1 and 2).

The open / closed state selection type window structure is often used for a guest room window of a hotel as a general application, and the fully closed state is used when a guest sleeps at night or shuts off external noise during the daytime or prevents rain. Used when you want to prevent blowing. In this fully closed state, the interlocking relationship between the input handle device and the drive control mechanism is disconnected, and the drive control mechanism cannot be operated even if the operation handle of the input handle device is turned.

The inside-down state is used when a guest wants to ventilate indoor air with external air. In order to shift to this state, it is necessary to establish an interlocking relationship between the input handle device and the drive control mechanism and to turn the operation handle of the input handle device to a predetermined angle. In the inwardly tilted state, the window shoji is not only held on the window frame by the horizontal axis of the lower frame part, but also in a locked state in which the tilt angle is limited to be constant by other members.

The inwardly open state is used when the cleaner wants to clean the window shoji without risk of falling from the window. In order to shift to the inwardly open state, it is necessary to establish an interlocking relationship between the input handle device and the drive control mechanism, and further rotate the operation handle of the input handle device to the required angle.
In the inwardly open state, the window shoji is only held by the window frame by the vertical axis of the side frame, and in other places it is in an unlocked state in which movement is not constrained by the window frame. The opening angle can be changed freely.
