Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a window stay that supports a shoji incorporated in a window frame so as to be freely opened and closed.
[0002]
[Prior art]
When supporting the shoji that opens and closes the opening of the window frame, if it is supported to open and close using a hinge, the end of the swinging center side cannot be brought into close contact with the window frame in the closed state of the shoji, and a good sealing is achieved. I can't get sex. In addition, since the shoji is opened and closed around the hinge fixed to one of the vertical frames of the window frame, only a small gap is formed between the vertical frame and the open window frame. However, it is impossible to insert a hand outdoors through the gap, and it is impossible to wipe and clean both sides of the shoji from the indoor side.
[0003]
In order to eliminate such inconvenience, when the shoji is closed, the suspension side of the shoji can be pulled toward the window frame side to improve the sealing performance, and in the open state of the shoji, openings are formed on both sides thereof. There has been proposed a window stay that can open the shoji.
[0004]
[Problems to be solved by the invention]
By the way, in the conventionally known window stay, when the shoji is in the closed state, the structure of the pulling mechanism that draws the shoji toward the window frame is complicated, and it takes time to manufacture and process the parts. The window stay has a large number of parts and is difficult to assemble.
[0005]
An object of the present invention is to provide a window stay that can be easily assembled with a small number of parts.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, in the present invention, a belt-like frame plate attached to the window frame side, a shoji plate attached to the shoji side, and one end portion of the frame plate are rotatably connected. The other end is pivotally connected to the shoji plate and a slider whose one end is pivotally connected to the shoji plate, and the frame plate is provided with a guide rail extending in both end directions. The guide rail is provided with a guide groove for guiding the movement of the other end of the slider, and an end opening of the guide groove is formed at the end of the flange formed inward from the opening edge of the guide groove. A closing guide piece is provided, and the other end portion of the slider slides along the guide groove, and the shoji plate starts to come into contact with the guide piece from a close position where the shoji plate is substantially parallel to the frame plate vertically. A guide projection that changes the orientation of the slider by movement along the inner surface of the guide piece, and a guide surface that is opposed to the guide projection with a gap between which the flange is inserted are provided on the guide surface. Adopts a configuration in which a notch portion into which the coupling portion of the flange and the guide piece can be fitted is formed at a position facing the guide protrusion.
[0007]
If comprised as mentioned above, the guide protrusion formed in the slider will begin to contact the inner surface of a guide piece immediately before the shoji plate is parallel to the frame plate. When the shoji plate is further pulled to the closed state where it overlaps the upper surface of the frame plate, the guide protrusion slides along the inner surface of the guide piece, and the slider has the end on the connection side to the shoji plate facing the window frame. The shoji, to which the shoji plate is attached, can be drawn toward the window frame by the jogging in the moving direction.
[0008]
In this way, by providing a guide piece at the end of the guide rail and forming a guide projection on the slider, when the shoji is closed, the shoji can be drawn toward the window frame, so the window stay can be placed on the frame plate, shoji. It can be formed of four parts, a plate, an arm, and a slider, and the number of parts of the window stay can be reduced.
[0009]
Here, the guide piece may be an inclined shape having an inclination with respect to the length direction of the guide rail, or may be an arc shape having a flange of the guide rail as a tangent. When the guide piece is inclined, the guide piece may be linear or arcuate.
[0010]
On the other hand, the guide protrusion may be a pin that moves along the inner surface of the flange of the guide rail, or may be a diamond having a rounded corner.
[0011]
