Description

  The present invention relates to a screen door having an insectproof net removable from the room side with respect to a screen door frame, and a kit for a repair screen door for assembling a repair screen door having a net detachable from the room side using an existing screen door frame. It is a thing.

  In the conventional practice of stretching the net on the screen door frame, the net is made of rubber (pressing beat) or the like with respect to the net fixing groove provided on the inner periphery of the frame on the outdoor side of the screen door frame. It is common practice to press with the resin push rim. It is necessary to fix the net to the screen door frame in order to clean the net and replace it as it is damaged. And the net is attached to and removed from the screen frame by removing the screen frame from the sash of the building, etc., removing the net, placing the screen frame on the floor surface of a large area indoors, and for new net or repainting It is necessary to carry out the work of re-installing the cleaned net on the screen frame, and it is not easy to carry out such work efficiently unless it is particularly experienced. In addition, when the installation place of the screen door is an outer wall surface of a high floor, the attaching and detaching work and the like are accompanied by danger.

  Furthermore, in recent years, in order to prevent the screen door installed on the outer wall of the middle and high floors from falling, consideration is given to such screen door being fixedly installed on the frame of the building opening or installed on the indoor side of the sash. Therefore, there is a demand for removing or stretching the net from the indoor side to the screen door frame, and a means for doing this is also proposed, so the net to the outdoor side of the screen door frame conventionally used conventionally It is also desired that the screen door frame be able to attach and detach the net by work from the indoor side, even for those that are stretched.

  In order to cope with such a problem, Patent Document 1 proposes a system in which the attachment and detachment of the net to the existing screen door frame can be simplified. In the previously proposed one, an attachment having a substantially Z-shaped cross section is incorporated into a net fixing groove provided on the outdoor side surface of the screen door, fixed to the net attachment portion by bonding or screwing. An insect repellent net on which the other surface fastener fixed to the four circumferences of the net member is fixed to one surface fastener attached to the indoor side surface of the hanging piece is removable from the indoor side.

  However, in the insect-repellent net attachment structure in Patent Document 1 described above, it is necessary to replace the insect-repellent net with respect to the net fixing groove provided on the frame inner periphery of the outdoor side face of the screen door frame. It is difficult to cope with the fall prevention measures of the screen door when it is an outer wall surface of a floor. That is, the net fixing groove in the above-mentioned existing screen door is not only a narrow groove that opens to the outside of the screen door frame until it gets tired, but the screen door frames of existing companies are not manufactured with the same size. Therefore, it is clear that the member corresponding to the attachment may fall along with the insect net if at least the groove itself is used for fixing the net.

  Also, as described above, in recent years there has been a demand for removing and stretching the net from the indoor side in the screen door frame, but it has been conventionally practiced to replace the net on the screen door frame. The work, that is, pushing the net together with the string-like rubber (presser beat) or the resin-made pressing edge against the net fixing groove provided on the inner circumference of the screen frame is troublesome. Generally, it is generally not desired because the net is likely to be broken near the mounting portion, and so the development of a screen door structure that allows easy replacement of the net by other simple means is available. It is strongly desired.
