BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a screen door detachment preventer for preventing the screen doors to be detached between the upper and lower screen door rails provided on the upper and lower frames of the sash, and more particularly for screen doors suspended from the sash upper frame. While the upper rail is sandwiched between the indoor and outdoor upper projecting members projecting parallel to the longitudinal direction above the screen doorway, the screen door is attached, and the movement allowance of the screen door upward is restricted. The present invention relates to an integrally formed screen door stopper for preventing the screen door from coming off.
[0002]
[Prior art]
Conventionally, a screen door is provided for insect control on the outermost side of the shoji that opens and closes the windows and doors of the building. This screen door is not always used like a glass shoji, but is used only during periods when insects are likely to occur, such as in summer, so it is required to be inexpensive and lightweight so that it can be easily removed. Often it can easily fall off the sash frame.
[0003]
In general, the screen door is installed between the upper and lower screen door rails provided on the sash frame by the “Kendon method”, that is, the upper screen door rail hanging from the sash upper frame is projected in parallel above the screen door ridge. The door cart mounted in the lower arm of the screen door is placed on the lower rail for the screen door protruding from the sash lower frame after being lifted so as to be sandwiched between the indoor and outdoor upper protruding members. After installing, the horizontal door upper surface between the base part of the indoor and outdoor upper projecting members and the lower end of the upper door rail for the screen door suspended from the sash upper frame There is a considerable gap between them. Because of the presence of this gap, the screen door can be attached and detached quickly, but this also causes the screen door to come off.
[0004]
For example, as shown in the sectional view of the sash with the screen door of FIG. 9 attached, the screen door 7 has the screen door upper rail 3 suspended from the sash upper frame 1 in the longitudinal direction over the screen door ridge 9. A lower part for a screen door in which a door wheel 17 mounted in a screen door sill 16 is projected to the sash lower frame 2 after being lifted so as to be sandwiched between the indoor-side and outdoor-side upper projecting members 12, 13. Mounted on the rail 4 by “Kendon type”. In this state, there is a gap between the upper surface of the horizontal member 10 between the base portions of the indoor and outdoor upper projecting members 12 and 13 in the screen door ridge 9 and the lower end of the screen door upper rail 3 suspended from the sash upper frame 1. Since the screen door 7 can be moved upward, the door wheel 17 is completely dropped from the screen door lower rail 4 protruding from the sash lower frame 2 due to a slight vibration or the like while the screen door 7 is running. The door wheel 17 may come off and the screen door 7 may be distorted and cannot move.
[0005]
Therefore, in order to prevent such a phenomenon from occurring, a plate-shaped screen door stopper that has a long hole in the vertical direction in order to regulate the upward movement allowance of the screen door ridge is conventionally used. Is a screw threaded at a predetermined position on an indoor upper projecting member that is projected above the screen door ridge, and is arranged so that is positioned slightly below the lower surface of the horizontal portion of the sash upper frame. A method of fixing to a sash upper frame by screwing and fixing to a sash upper frame has been adopted.
[0006]
However, this method not only requires a screwdriver to rotate the screw when adjusting the installation height position of the screen door stopper, but also the position of the screen door stopper is at the top of the screen door ridge. Therefore, when adjusting the installation height position of the screen door stopper, you must prepare a stepladder, and if the screws are weak, the screen door stopper will drop downward due to gravity. There was a disadvantage that the screen door detachment was damaged when the screw was not tightened and the screws were tightened strongly.
[0007]
[Problems to be solved by the invention]
