BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a structure of a slat of a light shutter, and more particularly to an improvement of an outer surface structure relating to noise generated from the slat.

[0002]

2. Description of the Related Art An ordinary lightweight shutter forms a shutter curtain by connecting a large number of slats up and down to open and close an opening of a building, but the shutter curtain is wound around a winding shaft. Since it is based on the basic operation of rewinding from there, the structure of the slat forms an interlock part on the upper and lower edges, and from the strength of itself,
The main body is formed by bending the main body in the vertical direction. However, in order to open and close the opening, it is necessary to form a part of the outer surface of the building, particularly at the time of closing, so that the outer surface of each slat is also required to be flat.
Therefore, a slat forming a shutter curtain having a flat outer surface or a panel shutter has been provided.
It is a relatively heavy structure equipped with an electric drive device, and flattening of the outer surface is not yet widespread in the light-weight shutter of the wind-up type that mainly uses manual operation because of its strength. .

[0003]

In the conventional lightweight shutter, noise from various parts generated when the shutter is opened and closed has become a problem. Among them, noise due to vibration of the slat itself and mutual noise in the engagement part of the interlock part have been problematic. Various measures have been taken to reduce the noise caused by the abutment noise, the friction caused by the relative rotation, and the friction generated between the guide rail during vertical movement. The noise that comes into contact with the slats around the shaft is amplified by the reverberation, especially in the shutter case, and the squeak noise is added.
In particular, when the slats are flattened, the slats are wound in a polygonal shape on the winding shaft, and the impact sound between the interlock portion and the main portion becomes a problem. Are to compete. In addition, the generation of noise is at the same time caused by the abutment between members, and is a matter directly related to minor damage to each part and peeling of paint, etc.It is also a defect related to the aesthetic problem on the outer surface of the building. there were.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The slat structure of the lightweight shutter of the present invention is as follows.
A detailed description will be given based on the drawings showing the embodiments. FIG.
It is a front view and a vertical cross-sectional view of a shutter curtain, 1 is a shutter curtain, 2 is a number of slats, 3, 3
Is a known interlock portion formed on the slat. Each slat 2 engages with an interlock portion 3 formed on the upper and lower edges to constitute the shutter curtain 1. In the present invention, the slat 2 is indicated by “10” and includes a main body 20 and an exterior material 30.

FIG. 2 is a sectional view of the slat according to the structure of the present invention exploded into main parts. A slat according to the present invention is indicated generally by the reference numeral 10,
The slat 10 includes a main body 20 that is a structural main part, and an exterior member 30 mounted on the outer surface thereof. First,
The main body 20 is made of aluminum and has a plate-shaped main body 2.
1 and the interlock portions 22 on both side edges thereof are integrally molded, and an engaging ridge 23 having a T-shaped cross section is formed on the outer surface of the main portion 21 on the upper and lower end sides near the interlock 22.
There are two protruding. In the present embodiment, the plate-shaped main portion 21
Is formed flat.

On the other hand, the exterior material 30 is formed into a plate shape using a rubber-based, synthetic resin or wood-based material, and upper and lower edges 31 and 32 are provided with the exterior material 30 of the adjacent slat 10. A convex and concave semicircular fitting surface is formed so as to connect in series. Therefore, the upper and lower widths of the exterior material 30 correspond to the substantial working width of the slats 10 connected by the interlock 22, and the horizontal length is equal to the length of the slats 10. The thickness of the exterior material 30 is equal in the vertical direction, the outer surface 33 is flattened, and the main body 2 of the slat 10 is formed.
The inner surface 34 that is in contact with 0 is in close contact with the main body 21 of the slat 10. On the inner surface 34 of the exterior material 30, the engaging ridges 23 are provided.
Are formed at two positions corresponding to.
When the exterior material 30 is formed of a rubber-based material or a synthetic resin, the engagement concave groove 35 may be integrally formed. When a wood-based panel is used, as shown in FIG. A concave groove 35 is formed in the aluminum profile 36 and is embedded in a groove 37 formed in the inner surface 34 of the exterior material 30.

FIG. 4 shows another embodiment of the slat 10. In this example, the plate-shaped main part 21 of the main body 20 of the slat 10 is curved up and down and is formed to project outward as is well known, so that the inner surface 34 of the exterior material 30 is correspondingly formed. It has a concave shape. In this case, no special processing is required for molding the main body 20, but a concave curved surface is required for molding the exterior material.

The configuration of the slat 10 of the present invention is not limited to the above embodiment. For example, the upper and lower edges 31 and 32 of the exterior material are not limited to convex and concave circles.
If they can be connected to each other, the fitting surface may be formed by a corresponding curved surface as shown in FIG. Further, the cross-sectional shape of the engaging ridge 23 formed on the main body 20 may be formed in an L-shape, and the engaging concave groove 35 may correspond to the same shape.
