DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retaining device for preventing a fitting mounted on a sash frame, such as a sliding sash, a sliding sash, and a screen door, from coming off the sash frame.

[0002]

2. Description of the Related Art To prevent a shoji (shoji) mounted on a sash frame from coming off the sash frame, see, for example, Japanese Utility Model Publication No. Sho 63-2.
As shown in Japanese Patent No. 4219, a stopper is attached to a lower frame of a shoji so as to be vertically movable by a screw, and the stopper is moved upward to approach a flange of a lower frame forming a sash frame, thereby moving the shoji upward. To make it smaller,
It is known that a stopper is moved downward to be separated from a flange of a lower frame so as to increase the amount of vertical movement of a shoji so that it can be mounted on or removed from a sash frame.

As a device for preventing the screen door from coming off, as disclosed in Japanese Patent Publication No. 6-84703, a main body, a stopper,
The operating body is provided with an elastic material, and the stopper moves to the upper position by moving the operating body to one side with the elastic material, and the stopper moves to the lower position by moving the operating body to the other side against the elastic material. In addition, there is known an operation body in which the operating body is engaged with an elastic locking piece of the main body and held at that position, and when the stopper is pressed down, the operating body and the elastic locking piece come off.

[0004]

In the former stopper, the stopper is moved up and down by a screw, so that the operation is troublesome.

In the latter device, the stopper is moved to the upper position by pushing down the stopper to remove the operating body and the elastic locking piece. Therefore, when the screen door is mounted on the sash frame, the screen door is lifted and the stopper is moved. Because the stopper is pushed down on the rail and the stopper is pushed down, the force to lift the screen door is greater than the force corresponding to the weight of the screen door, and it is very difficult to install the screen door.

Accordingly, an object of the present invention is to provide a fixture for preventing the fitting from coming off, which can solve the above-mentioned problems.

[0007]
