BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective screen connecting device for connecting protective screens such as a protective net and a protective sheet to each other.

[0002]

2. Description of the Related Art Generally, at a construction site, a scaffolding frame is assembled and a protective curtain is stretched over the outside of the scaffolding frame to prevent falling objects from scattering around the site to enhance safety. .

Since the protective curtain has a predetermined size, it is necessary to connect the protective curtain to each other when the protective curtain is stretched.

In connection with the protection curtain, conventionally, as shown in FIG. 6, a plurality of eyelet fittings 12 are attached to the outer peripheral portion of the protection curtain 11, and a string 13 is inserted into the eyelet fittings 12 to protect the protection curtain 11.
It connects each other.

[0005]

By the way, the connection of the protective screen 11 using the string 13 requires the string 13 to be sequentially inserted into each of the plurality of eyelet fittings 12 arranged in one direction, which is very troublesome for the connection. There is a problem that takes.

An object of the present invention is to solve the above problems and to provide a connecting device which can connect protective screens very easily.

[0007]

In order to solve the above problems, the present invention comprises a connecting frame having a pair of flanges provided on both sides of a plate body and a protective curtain connected by the connecting frame. A plurality of engaging pieces that face inward from the side edges of the flanges of the connecting frame are formed at equal intervals along the side edges of the flanges, and end portions of the protective curtain on the side connected by the connecting frames. Is folded back, and the side edges of the folded back piece are sewn at an interval corresponding to the width dimension of the engaging piece to form an insertion hole for the engaging piece between the sewn portions.

[0008] Here, in order to connect the connecting frame and the protective curtain more reliably, it is preferable to provide a notch capable of engaging with the end of the sewn portion at the base of the engaging piece.

[0009]

In the connecting device having the above structure, the engaging pieces provided on the pair of flanges of the connecting frame are inserted into the insertion holes of the pair of protective curtains to be connected to connect the pair of protective curtains.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, the connecting frame 1 has a U-shape in which a pair of flanges 3 and 3 are provided on both sides of a plate body 2.
A plurality of engaging pieces 4 facing inward are formed at equal intervals on the side edges of the flanges 3, 3. The width of the engagement piece 4 gradually increases from the tip to the root, and a pair of notches 5 are provided on both sides of the root.

The outer peripheral four sides of the pair of protective curtains 6 connected by the connecting frame 1 are folded back inward, and each folded piece 7 is folded.
The side edge of is sewn to the protective screen 6. As shown in FIG. 4, the sewing of the folding piece 7 of each folding piece 7 on the side connected by the coupling frame 1 is performed at intervals corresponding to the maximum width dimension of the engaging piece 4 of the coupling frame 1. An insertion hole 9 into which the engaging piece 4 is inserted is provided between the sewn portions 8 which are sewn.

The insertion hole 9 as described above is formed in each folded piece 7
It may be provided in each sewn part.

In the connecting device having the above-mentioned structure, when connecting the pair of protective curtains 6, the engaging pieces 4 provided on each flange 3 of the connecting frame 1 are inserted into the insertion holes 9 formed in the protective curtain 6. . By the insertion, the pair of protective curtains 6 are prevented from moving in a direction in which they are relatively separated from each other, and the pair of protective curtains 6 can be held in a connected state.

In the connection of the connecting frame 1 and the protective screen 6 as described above, when the connecting frame 1 and the protective screen 6 are relatively moved in the longitudinal direction of the connecting frame 6, as shown in FIG. 5
Engages with the end of the sewn portion 8, and the pair of protective curtains 6 can be connected more reliably by the engagement.

As shown in FIG. 5, by forming the hole 10 in the plate body 2 of the connecting frame 1, the connecting frame 1 can be connected to the scaffolding frame by the string inserted into the hole 10. It is possible to stabilize the attachment of the protective curtain that is stretched around the scaffold frame.

[0017]

As described above, in the connecting device according to the present invention, the protective curtain can be connected by inserting the engaging piece of the connecting frame into the insertion hole formed in the protective curtain. The two can be connected very easily.

Further, by providing a notch at the base of the insertion piece, the end of the sewn portion can be engaged with the notch, so that the connecting frame and the protective screen can be connected more reliably. .
