Description

The present invention relates to a screen door in which an insect repellent net can be attached to and detached from the indoor side of the screen door frame, and a kit for a modified screen door for assembling a repaired screen door in which the net can be attached and detached from the indoor side using an existing screen door frame. It is a thing.

In the conventional method of attaching a net to a screen door frame, a string-shaped rubber (holding beat) or a string-shaped rubber (holding beat) is used for the net fixing groove provided on the inner circumference of the frame on the outdoor side of the screen door frame. It is customary to push it together with a resin ridge. It is necessary to fix the net to the screen door frame in order to clean the net or replace it due to damage. Then, to attach / detach the net to those screen door frames, remove the screen door frame from the sash of the building, remove the net, place the screen door frame on the floor surface of a large area indoors, and use it for a new net or replacement. It is necessary to reattach the washed net to the screen door frame, and it is not easy to perform such work efficiently unless the person is particularly experienced. In addition, if the screen door is installed on the outer wall surface of a high-rise floor, there is a danger in the work of attaching and detaching the screen door.

Furthermore, in recent years, in order to prevent the screen doors installed on the outer walls of the middle and upper floors from falling, consideration has been given to installing the screen doors fixedly on the opening frame of the building or on the indoor side of the sash. Therefore, it is required to remove or stretch the net from the indoor side to the screen door frame, and a means to do so has been proposed. Therefore, the net is applied to the outdoor surface of the screen door frame that has been generally used in the past. It is desired that the screen door frame can be attached to and detached from and replaced by the work from the indoor side even for the ones to be stretched.

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

However, in the mounting structure of the insect repellent net in Patent Document 1, it is necessary to replace the insect repellent net with respect to the net fixing groove provided on the inner circumference of the frame on the outdoor side of the screen door frame, and the installation location of the screen door is high. It is difficult to take measures to prevent the screen door from falling when it is the outer wall surface of the floor. That is, the net fixing groove in the existing screen door stile is not only a narrow groove that opens to the outdoor side of the screen door frame, but also the screen door frames of the existing companies are not manufactured with the same dimensions. Therefore, it is clear that if at least the groove itself is used for fixing the net, the member corresponding to the attachment may fall together with the insect screen.

Further, as described above, in recent years, it has been requested to remove or stretch the net from the indoor side to the screen door frame, but it seems that the net has been replaced with the screen door frame in the past. The work, that is, pushing the net into the net fixing groove provided on the inner circumference of the screen door frame together with the string-shaped rubber (holding beat) or the resin ridge is troublesome. It is generally not desired because the net is easily broken near the mounting part, so the development of a screen door structure that allows the net to be easily replaced by other simple means has been developed. It is strongly desired.
