[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter for winding a shutter curtain into an n-sided shape, and more particularly, to a shutter provided at both ends in the longitudinal direction of a slat of a polygonal winding shutter. It is related to wind resistant hooks.

[0002]

2. Description of the Related Art When a slat is curved due to surface pressure applied to a shutter curtain, a guide rail is provided at an end of the slat.
Windproof hooks may be provided at the longitudinal end of the slat to prevent it from slipping out of the slat. However, if the shape of the hook provided on each slat is the same,
When winding the shutter, the hooks interfere with each other, so that the shutter curtain cannot be wound.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been conceived to improve the problem, and does not hinder the winding of the shutter curtain. It is an object of the present invention to provide a wind-resistant hook for a polygon winding shutter.

[0004]

In order to achieve the above object, a technical means adopted in the present invention is a shutter car constructed by connecting a plurality of slats in a vertical series.
A windproof hook integrally formed with end fittings provided at both ends in the longitudinal direction of a slat of a winding shutter for winding a ten in a polygonal shape. The hook engages with a groove formed in a side wall of a guide rail. The hooks provided on the adjacent slats do not interfere with each other by having different shapes of the hooks provided on the slats adjacent to each other in a wound state. Is what you do.

[0005]

According to the present invention, the shapes of the hooks provided on the slats adjacent to each other in the wound state are made different, so that when the polygonal wind-up shutter having the wind-resistant hook is wound up, the shutter is opened. It does not hinder the winding of the curtain.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a first embodiment of the present invention; FIG. 1 is a view showing a wind-resistant hook 1 integrally formed with end pieces provided at both ends in the longitudinal direction of a slat 9. The hook 1 is composed of a hook portion 2 and a base 3 having a role as an end piece. Become. The base 3 is mainly composed of a vertically long metal plate having a height substantially equal to the height of the slat 9, and L-shaped bent portions 3 a and 3 b formed at both upper and lower ends in the height direction by bending vertically to the plate surface. A bent portion 3d is formed by bending a part of the side end vertically at a side end located on the slat side, and a hook portion 2 is formed to extend at a central portion of the other side end. At the same time, a bent portion 3c is formed by vertically bending the side end portions located above and below the hook portion 2. As shown in FIG. 4, the hook portion 2 is formed in an L-shape in plan view, and the groove portion 6 formed in the side wall portion of the guide rail 6 is formed.
a. The hook 1 composed of the hook 2 and the base 3 is integrally formed by pressing a steel plate.

The L-shaped bent portions 3a and 3b are composed of a tongue-shaped bent portion 3a in the height direction and a bent portion 3 in the longitudinal direction of the slat.
The bent portion 3b in the longitudinal direction of the slat is an engaging portion with the connecting piece 4. After engaging the engagement portion with an engagement groove (not shown) provided in the connection piece 4, the tongue-shaped bent portions 3 a located at the upper and lower ends of the base 3, and the connection piece 4
By inserting the screw 13 into the insertion holes 3e and 4b formed in the horizontal frame and screwing into the screw holes 10b provided in the horizontal frame 10, the hook 1, the connection piece 4 and the horizontal frame 10 are integrated. You.

Reference numeral 5 denotes a connecting member for connecting the hook 1 and the slat 9. The connecting member 5 is provided with a groove 5 a for fitting with the base 3, and the depth of the groove 5 a is equal to the width of the base 3. The bent portion 3d is in contact with the bottom 5b of the fitting groove 5a in the fitted state. The slat connecting member 5 is provided with a groove 5c that opens in the opposite manner to the fitting groove 5a, and the slat 9 is loosely fitted by the groove 5c. The hook 1 and the slat connecting member 8 are integrated by fitting them together, and then passing a spring pin (not shown) through the insertion holes 3f and 5d provided respectively.

FIG. 5 is a view showing a state in which the shutter curtain 8 having the slats 9 provided with the hooks 1 of the present invention is wound, and the shutter curtain 8 of the winding shutter is shown.
Is wound on the wheel 7 in a hexagonal shape. Shutter
The curtain 8 is provided with an interlock connecting portion 10a provided on a horizontal frame 10 which is integrally attached to upper and lower ends of the slat 9 via a horizontal frame connecting member 11 and a horizontal frame connecting member. Interlock connection receiving part 1 provided in 11
They are connected in series by the engagement of 1a. In the embodiment, the slat 9 is a transparent resin panel, and the shutter curtain 8 has a horizontal frame connecting member 11 provided on the outer peripheral surface of the wheel 7 in contact portions 7a, 7b,. . . Since the slats 9 are wound in a hexagonal shape by being supported in contact with 7f, contact between the slats 9 is prevented. In the embodiment, the contact portions 7a, 7b,. . . Is set so as to gradually increase from the contact portion 7a located on the winding start side, in increments of six equal divisions of the winding diameter difference between the first and second turns of the shutter curtain 8. . As a result, the six slats 9 forming each winding layer can have the same height dimension, and the winding end slats of each winding layer have special dimensions to absorb changes in the winding diameter between the winding layers. Becomes unnecessary.

Here, the windproof hook 1 of the present invention will be described with reference to FIG. 5 shows slats 9a, 9b and 9c provided with hooks in order from the wheel 7 side. The slat 9a has a hook having two chevron hooks 2a, and the slat 9b has a chevron hook. Part 2b
A hook having two chevron-shaped hook portions 2c is attached to the hook and slat 9c. Slats 9a and 9b, 9b and 9c adjacent to each other in a wound state
Have different shapes from each other,
This prevents the hook portions of the hooks provided on the adjacent slats from interfering with each other in the wound state. In the present embodiment, a hook having one angled hook portion and a hook having two angled hook portions have been described. However, the shape and the number and positions of the hook portions are not limited thereto. In short, any shape may be used as long as the shape of the hook is changed so that the hook provided on the adjacent slat does not interfere with the wound state. The hook is
It is formed integrally with the base corresponding to the metal end by pressing a steel plate. Further, in the polygonal winding shutter, the size of the metal end is set to the height of the slat constituting each winding layer. In addition, since it is necessary to change the shape for each winding layer, there is no problem by changing the shape of the hook for each winding layer. 2, 4 and 5, reference numeral 12 denotes an end cap provided at the end of the hook. When the end surface of the end cap 12 is processed, the shutter curtain 8 may swing right and left. To
The guide rail 6 and the hook 1 are prevented from colliding and being damaged.

[0011]

In summary, the present invention is directed to a winding shutter having a plurality of slats connected in series in the vertical direction to wind a shutter curtain in a polygonal shape. A wind-resistant hook integrally formed with an end fitting provided on the guide rail, wherein the hook has a hook for engaging with a groove formed on a side wall of the guide rail, and is adjacent to each other in a wound state. By making the hooks provided on the slats different in shape so that the hooks provided on the adjacent slats do not interfere with each other, even if the shutter is a polygonal wind-up shutter having a windproof hook, the shutter car can be used. There is no hindrance to winding the ten. Further, since the hook is formed integrally with the end piece, the hook having a different shape may be formed simultaneously with the formation of the end piece having different dimensions, and there is no problem due to the change in the shape of the hook.
