[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a rewindable screen door that opens and closes in a double-sided manner along upper and lower horizontal frames of a screen frame, and more specifically, a movable frame for opening and closing, a spring, and a driving source for winding a net. Holding the upper and lower ends of the winding shaft, and attaching the base ends of the nets to the left and right vertical frames of the screen frame, respectively, while guiding the upper and lower sliding members of the movable frame to the upper and lower horizontal frames of the screen frame. The present invention relates to a double-sided rewindable screen door that opens and closes the net.
[0002]
[Prior art]
In the case of installing a rewindable screen door that shields the left and right openings in the sliding door that opens and closes in a sliding manner, as shown in FIGS. It is conceivable to install winding screen doors that are linked to the opening and closing operations of the sliding doors. The net length of these wind-up screen doors is generally set to a length corresponding to the width of each sliding door opening, although there is some allowance.
[0003]
However, in the above retractable screen door, since the horizontal frames of the left and right screen doors are shared in order to make the installation space of the screen door outside the sliding door as compact as possible, the net length of the screen door is erroneously set. It may be considered that the screen door is operated to a position exceeding the position, and the net or a connecting portion between the net and the winding shaft may be damaged.
[0004]
As means for dealing with such a problem, it is also conceivable to provide a stopper fixedly at the center of the horizontal frame of the screen door frame to limit the moving range of the movable frame for opening and closing operation in each screen door. The position of the movable frame in the fully stretched state of the net of the screen does not always coincide with the center of the horizontal frame, and the position of the movable frame slightly exceeds the center (see FIG. 5). If a stopper is fixedly provided at the center, there arises a problem that any screen door cannot be completely extended.
[0005]
[Problems to be solved by the invention]
In view of the above, a technical problem of the present invention is to provide a rewind screen door that can set an appropriate moving range of a movable frame for opening and closing in a revolving screen door that is open to the left and right. .
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a net using a spring as a drive source for winding along a horizontal frame above and below a screen frame so that the net can be opened and closed in a double-sided manner, and a movable frame for opening and closing the net. In the rewind type screen door which opens and closes the net while guiding the upper and lower sliding members to the upper and lower horizontal frames of the screen door frame, each movable frame is moved to the center of the upper horizontal frame of the screen door frame. Left and right movable stoppers are provided to allow the range to a position slightly beyond the center of the horizontal frame.
[0007]
In a more specific configuration of the winding screen door, the stopper is provided on a side frame of a stopper body provided on a horizontal frame on which a sliding member on an upper portion of a movable frame slides. And a movable member in which the sliding member on the upper part of the movable frame comes into contact with the elongated hole so as to be freely movable along the elongated hole. The upper and lower ends of the winding shaft, which uses a spring as a drive source for winding the net, are held at the upper and lower ends, and the base ends of the net are attached to the left and right vertical frames of the screen frame, respectively.
[0008]
In the winding screen door, when the movable frame is operated to stretch the net, the net or the connecting portion between the net and the winding shaft is damaged due to the excessive withdrawal of the net due to the presence of the movable stopper. Not only can be prevented, but also the movable frame can be operated to a desired position slightly beyond the center of the horizontal frame of the screen door frame (at least a position overlapping with the vertical frame of the sliding door in the fully opened state or the fully opened state), so that there is enough room in the net. Can be pulled out to a completely stretched state.
