BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a windproof hook for an architectural shutter installed on an opening of a building.

[0002]

2. Description of the Related Art
In this type of architectural shutter, guide rails are provided on both sides of the opening to guide both side edges of the shutter curtain, and the shutter curtain is wound and unwound on a winding drum provided above the opening. In some cases, the opening is opened and closed. However, in a configuration in which both side edges of the closed shutter curtain are merely loosely fitted to the guide rail, when a strong wind such as a typhoon blows, the shutter curtain receives a large wind pressure. May be bent in the front-rear direction and come off the guide rail. In order to prevent the shutter curtain from coming off the guide rail due to strong wind pressure, a wind-resistant hook is provided on both sides of the slat constituting the shutter curtain so as to protrude beyond the thickness of the slat in the front-rear direction. Attempts have been made to lock onto the guide rail when the tar curtain is bent to prevent it from coming off. By the way, it is more effective to increase the amount of projection of the windproof hook to prevent the removal.However, when a shutter curtain provided with such a large amount of windproof hook is wound on a winding drum, ,
Since the wind-resistant hooks interfere with each other between adjacent winding layers, smooth winding cannot be performed, and the winding posture is destroyed. Conventionally, windproof hooks have to sacrifice windproof performance by using small protrusions, and as a result, windproof hooks are limited to being attached to all or at most every other strap. Therefore, there is a problem that the number of parts is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has been made in order to provide a wind-resistant hook in an architectural shutter capable of eliminating these disadvantages. In a building shutter in which a shutter curtain whose both side edges are guided by guide rails provided in a section is spirally wound around a take-up drum, a slat constituting the shutter curtain includes:
In providing a windproof hook that locks to the guide rail and prevents the shutter curtain from coming off the guide rail, the shutter curtain shall be provided with a windproof hook with intermittent slats, and with the windproof hook. The slat is provided at a position where the slat of the adjacent winding layer does not have a windproof hook in a spiral state in which the shutter curtain is wound on the winding drum.
In addition, the slat with windproof hook has no windproof hook
It is characterized in that it is stronger than the slat .

According to the present invention, this structure ensures that the shutter curtain does not come off from the guide rail, but does not interfere with the windproof hook when the shutter curtain is wound. is there.

EXAMPLES The following will describe a real施例of the present invention in the drawings. In the drawings, reference numeral 1 denotes a shutter curtain of an architectural shutter built at an opening of a building, and the shutter curtain 1 is wound inside a shutter case 2 provided above the opening. The opening and closing of the shutter curtain 1 is lifted up and down by being wound and unwound by the drum 3. Both sides of the shutter curtain 1 are loosely engaged with guide rails 4 erected on the left and right sides of the opening. Thus, the up and down movement of the shutter curtain 1 is guided, all of which are conventional.

Reference numeral 5 denotes a wind-resistant hook which is integrally attached to both sides of a slat 1a constituting the shutter curtain 1. The wind-resistant hook 5 is formed of a plate material bent substantially at right angles. One side is a mounting side 5a that is integrally provided on the side face plate of the slat 1a, and the other side is a locking side 5b that projects rearward beyond the thickness of the slat. Then, the shutter curtain 1 is loosely engaged with the guide rail 4 and guided.
In this case, the engagement side 5b of the windproof hook 5 is guided by being located at the guide portion 4b on the deep side of the groove formed with a wider groove than the guide surface 4a of the shutter curtain 1. When the shutter curtain 1 is deflected by the wind pressure due to a strong wind or the like and tries to come off the guide rail 4,
b is configured to engage with the guide surface 4a of the guide rail. Incidentally, the windproof hook 5 is provided not intermittently on all the slats 1a of the shutter curtain 1 but intermittently. That is, as shown in FIG. 1, the shutter curtain 1 is composed of a group of a single or a suitable number of wind-resistant hooks 5 and a group of slats A with wind-resistant hooks provided on both sides, and a slat without the wind-resistant hook 5. It is composed of a group B and as shown in FIG.
When the shutter curtain 1 is spirally wound on the winding drum 3, the slacks 1 a of the adjacent winding layers are provided with the wind-resistant hook 5 and the wind-resistant hook 5. The wind-resistant hook 5 is positioned adjacent to the one without the wind-resistant hook 5, that is, the wind-resistant hook 5 is positioned so as not to overlap in the radial direction.

In the embodiment of the present invention constructed as described above, when the shutter curtain 1 is spirally wound around the winding drum 3, a slat group A with a windproof hook is provided intermittently. As a result, the wind-resistant hook 5 is set so as not to overlap in the radial direction.
The shutter curtain 1 is reliably prevented from coming off the guide rail 4 even if the windproof hook 5 is provided intermittently. Can be.

Further, when this is implemented, FIG.
5, as in the embodiment shown in FIGS. 6, the wind hook with Suratsuto group A wind hooks 5 are provided, it may be formed in a thick plate material thickness than without hook Suratsuto group B, Suratsuto front and back direction as the (longitudinal direction) or by increasing the thickness of, or Fuoro type, it the wind hook
The strength up is measured compared to the slatted
This is convenient because wind resistance can be further improved.

[0009]

[Effects] In summary, since the present invention is configured as described above, when the shutter curtain is spirally wound around the winding drum, a slat with a windproof hook is provided intermittently. As a result, the wind-resistant hook does not overlap in the radial direction, and as a result, the wind-resistant hook can be made to have a large protrusion amount that can be securely locked to the guide rail.
It is possible to reliably prevent the shutter curtain from coming off the guide rail. And this one is wind resistant
The hook with hook is stronger than the one without hook.
Wind resistance can be further improved
It is convenient that you can do it.
