Description

[Detailed explanation of the idea] This invention relates to a screen door that is attached to a window frame.

This type of screen door will be explained with reference to FIG. 1. A groove 3 is formed on the inner periphery of one side of a rectangular edge frame 1, and a net 2 is stretched over the entire side of this edge frame 1. The elastic material 4 is fitted into the groove 3 with the periphery of the net 2 interposed therebetween, and the net 2 is fixed to the edge frame 1 by this fitting.

However, this screen door is usually installed with the side where the screen 2 is stretched facing the outside, but one side of the screen door, that is, the side where the elastic material 4 is fitted (hereinafter, this side will be referred to as the facing side). has a structure in which the mesh surface and the frame surface are almost flush with each other, or the mesh surface is slightly tilted backwards, and there is no part on this surface for the fingertips to rest on. For this reason, when this screen door is slidably attached to a window frame, it is extremely difficult to slide the screen door without knowing the front surface, and there is a problem that the screen may be deformed or damaged during this operation.

The purpose of this invention is to provide a screen door that can be opened and closed smoothly from the outside, keeping the above points in mind.

In order to achieve this purpose, in the screen door of this invention, in the conventional screen door, a horizontal bar along the back side of the screen is spanned between the opposing vertical bars of the edge frame, and both ends of the horizontal bar are fixed to the vertical bars. Then, a suitable part of the net facing the horizontal bar is cut so that a dish-shaped pull tool can be inserted into the cut part, and a recess into which the pull tool is fitted into the horizontal bar is made to correspond to the cut part. formed by
A pull tool is inserted into the recess from the surface of the net through the cut point, the net around the cut point is held between the pull tool and the horizontal rail, and the pull tool is fixed to the horizontal rail.

If the screen door is configured in this way, since there is a pull tool on the front surface of the screen door, the screen door can be slid by hooking the tip of the finger on the pull tool.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the screen door according to this invention consists of a rectangular edge frame 1 and a net 2 attached to one side of the edge frame 1, and the edge frame 1 has a groove on the inner periphery of one side. 3, the outer periphery of the net 2 is fitted into the groove 3, and is held down by a string-like elastic material 4 fitted into the groove 3.

A horizontal bar 6 is provided along the back surface of the net 2 at an intermediate position between the opposing vertical bars 5, 5 of the edge frame 1. This horizontal bar 6 has a cylindrical part 7 on the upper and lower side edges, and is passed between the vertical bars 5, so that the groove 8 formed between the cylindrical parts faces the net 2, and the end part is the vertical bar. Supported by 5.

As this support means, as shown in Fig. 2,
A notch 9 is formed on the side edge of the inner wall 5' of the vertical bar 5, and an engagement protrusion 10 that can be engaged with the notch 9 is provided at the end of the horizontal bar 6. Alternatively, screw insertion holes may be formed at the ends of the horizontal beams 6, and the screws may be installed by screwing into the screw insertion holes from the vertical beams.

As shown in FIG. 3, the net 2 is cut into an X-shape at a portion facing the end of the horizontal beam 6, and a puller 12 is fitted into the cut portion 11 by widening the cut line.

The pull tool 12 includes an engagement recess 13 for placing a fingertip,
A flange 1 formed around the opening of this recess 13
4, and the peripheral wall of the engagement recess 13 can be fitted into the groove 8 of the horizontal beam 6. This pull tool 12 is inserted into the groove 8 of the horizontal crosspiece 6 through the cutting part 11.
and by tightening the screw 15, the horizontal bar 6
Fixed.

As shown in FIG. 4, the screws 15 may be screwed into the peripheral wall of the engagement recess 13 and pressed against the inner surface of the cylindrical portion 7 of the horizontal crosspiece 6, or screw insertion holes may be provided in the flange 14. It is also possible to form a tube, insert it into this insertion hole, and screw it into a screw hole formed in the cylindrical portion 7.

By attaching the pull tool 12 as described above, the net around the edge of the cut section 11 can be held between the pull tool 12 and the horizontal crosspiece 6, as shown in FIG.
It is possible to prevent the mesh 2 from tearing along the cutting line.

Note that an opening into which the pull tool 12 can be inserted is formed in the net 2, and the flange 1 of the pull tool 12 is placed around this opening.
4 and the cylindrical portion 7 of the horizontal crosspiece 6.

In this embodiment, the groove 8 constitutes the "recess" described in the "Claims of Utility Model Registration."

This invention is constructed as described above, and since a pull tool is provided on the front surface of the screen door that can be hooked with one's fingers, opening and closing operations can be easily performed even if the front surface is unknown.

In addition, since the periphery of the cut area of the net that was cut to install the handle is held between the pull and the crosspiece, it is possible to prevent the net from tearing at that point, and there is no hindrance to the operation of the screen main body. do not have.
