Description

  The present invention relates to a window opening / closing device used for an opening / closing window that is opened outward by a shoji, and more particularly to a window opening / closing device suitable for a horizontally long window or a vertically long window.

Windows provided on the walls of the building are one of the important factors that determine the exterior design of the building.
As the shape of such a window, a horizontal window and a vertical window are often employed from the viewpoint of not only design but also efficient lighting and ensuring privacy.
The horizontally long window has a feature that it is easy to obtain light from a high position by being arranged at a high position, and it is horizontally long so that it can be lighted for a long time and at a lower cost than the skylight. In addition, a vertically long window is more suitable for protecting privacy because light enters better than a horizontally long window if the area is the same, and a range that can be seen from the outside is narrower than a horizontally long window at a similar height position.

As an example of the arrangement of the windows, for example, a horizontally long window that can be opened and closed near the ceiling surface of the wall and a horizontally long window that can be opened and closed near the floor surface of the opposite wall are opened to open the hot window at a high position. Air can be released and cold air can be taken in by opening a low horizontal window.
In order to open a window for ventilation or ventilation, it is necessary to provide a manual or electric window opening / closing device.
As a window opening / closing device used for an opening / closing window that opens outwardly, a first arm (auxiliary arm, auxiliary arm, auxiliary base, pivotally supported by a casing (auxiliary arm side fixture, base body) fixed to the window frame. Some have a first swing arm) and a second arm (main arm, second swing arm) connected to a window frame and a shoji (see, for example, Patent Documents 1 to 3). In such window opening and closing devices, the tip of the first arm is pivotally connected to the intermediate portion in the length direction of the second arm, and the rotational force of the operation handle (operation unit, operator handle) attached to the casing is reduced. The shoji is opened and closed by transmitting directly to the base end portion of the first arm by the gear transmission mechanism and swinging the first arm.
