BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen door device installed on a window frame.

[0002]

2. Description of the Related Art Conventionally, a frame screen door or a roll screen door is generally adopted as a screen door installed in a window frame. However, in the case of the frame screen door, since the screen screen is always attached, there is a drawback that the screen screen obstructs the view and becomes dirty.
In addition, in the winter when the screen door is not needed, the screen door must be removed and stored separately. On the other hand, in the case of a conventional roll screen door, there is a problem that the window frame needs a storage space for the net body and a guide groove for the net body, which complicates the shape of the window frame and impairs the appearance. It was
Further, in the roll screen door, there is a defect that the insect repellent effect is insufficient because a gap is formed between the screen body and the guide groove. In order to solve such a problem, the present applicant provides a door frame of a screen door on the window frame so as to be movable in the left-right direction, and fixes one end of the mesh body to a winding shaft provided in the door frame,
The other end is fixed to the vertical frame of the window frame, and the net body is unwound and wound up with the movement of the door frame, and the upper and lower end edges of the net body and the upper and lower frames of the window frame, A screen door has been developed in which articulators that can be occluded to each other are provided, and a fastener slider that engages and disengages the articulators is provided on the door frame. But,
At the beginning of development, the door frame of the screen door was moved by suspending it from the upper frame.Therefore, when moving the door frame, the door frame may collapse depending on the place where force is applied. There was a fear that I could not move it smoothly. Further, since the winding spring is built in the winding shaft, there is a possibility that problems such as slack of the net body and excessive opening / closing force may occur due to an insufficient number of windings of the spring.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above situation and does not have a winding spring built in the winding shaft, and at the same time, pushes anywhere on the front end frame. Even if it does not fall down, the net is smoothly unwound,
An object of the present invention is to provide a retractable screen door device that can be wound up.

[0004]

In order to solve the above-mentioned problems, the technical means adopted by the present invention is to install a door frame of a screen door on a window frame so as to be movable in the left-right direction, and to attach one end of the mesh body to the door frame. The winding shaft is fixed to the inside of the window frame, and the other end is fixed to the vertical frame of the window frame. The upper and lower edges of the net body and the upper and lower frames of the window frame are provided with articulators that can be occluded to each other, and a fastener slider that engages and disengages the articulator is provided on the door frame. In the upper and lower frames of the window frame, guide rails having sides that are substantially parallel to the found surfaces of the upper and lower frames are provided in the left-right direction, and the upper and lower sides of a center shaft inserted into a hollow winding shaft. A main roller that rolls on one side of the above side is pivotally attached to both ends, and the upper and lower end portions of the doorframe are raised. An auxiliary roller that rolls on the other side of the side is provided to sandwich the side between the main roller and the auxiliary roller, and the center shaft has one end on the center shaft and the other end on the other side. It is characterized in that a rotation adjusting spring fixed to the winding shaft is wound.

[0005]

According to the present invention, since the main roller and the sub-rollers located at the upper and lower ends of the door end frame hold one side of the guide rail from both sides, when the door end frame is moved. The doorframe will not fall. At the time of unwinding and winding the net body, the rotation force of the main roller is transmitted to the winding shaft via the rotation adjusting spring.
The net body is wound or unwound while adjusting the error between the length of the net body to be unwound and the distance traveled by the main roller in one rotation.
