BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen door retaining device for preventing a screen door from falling off a sash frame.

[0002]

2. Description of the Related Art Generally, a screen door is slidable along an upper rail of an upper frame forming a sash frame and a lower rail of a lower frame forming a sash frame. The doors are detached and installed in the sash frame during use in summer or the like, so that ordinary users can easily install the screen door in the sash frame and remove it. For example, screen doors are erected between the upper and lower rails of the sash frame so that they can be removed. In this way, if the screen door is erected between the upper and lower rails in such a way that it can be detached and removed, not only will the vertical overlap between the lower part of the screen door and the lower rail be reduced, but also the overlap between the lower part of the screen door and the lower rail is expected. A gap may occur in the direction, and the screen door may come off from the sash frame due to bending of the sash frame, rattling when opening and closing the screen door, and the like. Also, as shown in Japanese Utility Model Application Laid-Open No. 61-32475, a sliding piece is provided on the lower frame of the door so as to be vertically movable, and when the door is erected, the sliding piece is moved upward to form a sash frame. There has been known a door stopper device that does not interfere with the lower rail of the frame, and that the sliding piece is moved downward after the erection and is fitted to the lower rail so that the lower part of the door does not come off from the lower rail. I have.

[0003]

In the above-mentioned device for preventing the door from coming off, the sliding piece is urged downward by a spring, and the pulling rod provided on the sliding piece is fixed to the indoor side wall of the lower frame with screws. Since it is a structure that holds it at the upper position, when installing and removing the door, loosen the screw and lift the sliding piece against the spring, and then tighten the screw again while holding the sliding piece at that position. An operation is required, and the operation is not only troublesome, but the screw is visible from the indoor side, so that the design is poor.

Accordingly, an object of the present invention is to provide a screen door retaining device which can solve the above-mentioned problem.
