DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hook fixed to a slat end of a shutter curtain so that the shutter curtain does not come off from a rail when a strong wind acts, and more particularly to a hook mounting structure.

[0002]

2. Description of the Related Art Referring to FIGS. 13 and 14, a structure for attaching a windproof hook of a conventional building shutter will be described.

[0003] In the figure, reference numeral 1 denotes a slat constituting a shutter curtain. The slat 1 is a drawn aluminum material, and the hollow interior is filled with a foamed resin. In the figure, reference numeral 2 denotes a hook. The hook 2 includes a flange 3 and a tongue 4 extending from the flange 3.

When attaching the hook 2 to the slat 1, the foamed resin at the end of the slat 1 is scraped out, the tongue 4 is inserted, and the tongue 4 and the end of the slat 1 are stapled. 5 was fixed.

The end of the slat 1 to which the hook 2 is fixed is slidably fitted on a rail (not shown). The width of the opening of the rail groove is smaller than the width of the flange 3, and when the flange 3 is engaged with the rail when the slat 1 is pulled out, the slat 1 can be removed from the rail. That is, removal of the shutter curtain from the rail is prevented.

[0006]

In the above-mentioned conventional structure for mounting a wind-resistant hook, it is necessary to scrape out the foamed resin, and this requires work for a large number of slats, which is troublesome. Further, since the scraping is performed from the end of the slat 1, it is necessary to work according to the shape of the end of the slat 1, and when the tongue 4 of the hook 2 is inserted, the work of the end of the slat 1 is required. Work must be performed according to the shape, automation is difficult and it has to rely on manual work, efficiency is poor, and the means of fixing the hook to the slat is by stapler, so mechanical strength is insufficient and hook There was a problem such as that it might come off.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a structure for mounting a windproof hook of a shutter for a building, in which the hook can be easily mounted and which has high working efficiency.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a windproof hook mounting structure for a building shutter in which a slat end is crushed by a press and a hook is fixed to the crushed end.
Further, the hook has a flange portion and a fixing portion, and the fixing portion is brought into contact with one side surface of the crushed end portion, and the end portion and the hook are fixed by eyelets to a windproof hook mounting structure of a building shutter. In addition, the hook has a flange portion and a bifurcated fixing portion, the crushed end is inserted into the fixing portion, and the end and the fixing portion are fixed to each other by eyelets. This is related to the mounting structure, and the work of attaching the hook is crushing of the end of the slat by pressing and fixation by eyelets, and no cumbersome work such as scraping of the foamed resin is required.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

A first embodiment will be described with reference to FIGS.

The hooks 11 are fixed by eyelets 12 at intervals of the slats 10, 10,... The inside of the slat 10 is filled with a foamed resin 13 for heat insulation.

The hook 11 will be described with reference to FIGS.

The hook 11 has a flange portion 15 perpendicular to the slat 10, a flat intermediate portion 16 parallel to the slat 10, and a fixing portion 17 curved substantially in the same manner as the slat. The fixing portion 17 is provided with a fixing hole 18 through which the eyelet 12 penetrates.

When the hook 11 is fixed to the slat 10, the end 19 of the slat 10 is
Press into the same shape as the 0 curve. The foamed resin 13 in the slat 10 is crushed, and the slat 10 itself is pressed. This press work is performed at a factory before shipping the shutter curtain. The fixing portion 17 of the hook 11 is applied from one side of the end portion 19, and a hole for eyelet is formed in the slat 10, and at the same time, the eyelet 12 is inserted and caulked. The hook 11 is firmly fixed to the end 19 of the slat 10 by caulking. Thus, the foamed resin 1 at the end of the slat 10
The hook 11 can be fixed to the end of the slat 10 without having to scrape out 3. Further, the eyelet position is in the fixing hole 1.
8, the eyelet work can be mechanized by using the fixing holes 18.

The rail groove 20 has an opening narrower than the flange 3, and the ends of the hook 11 and the slat 10 are housed in a rail (not shown), and extend along the rail. The shutter curtain moves up and down.

When the shutter curtain bends due to an external force such as wind pressure, the hook 11 is engaged with the rail to prevent the end of the shutter curtain from coming off the rail.

A second embodiment will be described with reference to FIGS.

First, in FIG. 11 and FIG.
Will be described.

The hook 21 has substantially the same outer shape as that of the hook 11, and has a flange portion 15 perpendicular to the slat 10, a flat intermediate portion 16 parallel to the slat 10, and a bifurcated shape. The fixing portion 22 is sequentially provided, and the fixing portion 22 is provided with a fixing hole 18 through which the eyelet 12 penetrates.

When the hook 21 is fixed to the slat 10, the end 19 of the slat 10 is pressed into a flat plate so as to substantially coincide with the center of the thickness of the shutter curtain (see FIG. 9). The foamed resin 13 in the slat 10 is crushed, and the slat 10 itself is pressed.

At the fixing portion 22 of the hook 21, the end 1
9 is inserted into the end 19 so as to hold the eyelet 9, a hole for eyelet is formed in the slat 10, and
Insert 2 and caulk. The hook 21 is firmly fixed to the end 19 of the slat 10 by caulking. Thus, there is no need to scrape out the foamed resin 13 at the end of the slat 10, and the hook 21 can be fixed to the end of the slat 10.

[0022]

As described above, according to the present invention, the work of fixing the hook to the slat can be performed by pressing the end of the slat and the eyelet of the hook. In addition, the hook can be mechanically fixed to the end of the slat, so that the work efficiency can be greatly improved. Further, since the means for fixing the hook to the end of the slat is formed by eyelets, it has an excellent effect of being secure and strong.
