【Example】

 1 is an exploded perspective view showing an embodiment of the structure of the shutter according to the present invention, and FIG. 2 is a plan view of the structure of the shutter according to the embodiment. First, as shown in FIG. 1, the slat 2 constituting the slat curtain 1 according to the present invention has one surface 2a, which is a front surface, formed to be substantially smooth, and the other surface 2b, which is a back surface, is curved and recessed. It is formed in a concave shape and has a hollow portion 2c filled with a sound deadening material, a hook-shaped upper engaging connection portion 3 is formed at the upper edge, and an opening is narrowed at the lower edge. The lower engaging connecting portion 4 of is formed. Then, the slat 2 is constituted by connecting the plurality of slats 2 by engaging the upper and lower engaging connecting portions 3 and 4 with each other and connecting them.

Next, as shown in FIG. 1, the retaining piece 5 attached to the slat 2 is roughly composed of a base portion 6 and an extending portion 7 which are integrally formed. The base 6 of the retaining piece 5 has a block-like shape formed slightly smaller than the inner diameter of the hollow portion 2c of the slat 2, and is fitted into the hollow portion 2c from the end portion 2d. , Stitch processing 8 etc. are performed and fixed.

The extending portion 7 of the retaining piece 5 has the same shape as the outer shape of the slat 2, that is, the same shape as the vertical cross section of the slat 2, and one surface 7a is formed smooth and the other surface 7b is concave. The slat 2 is formed in a shape similar to that of the slat 2, and as shown in FIG. 1, the width of the slat 2, that is, the length between the upper and lower edges of the engaging connecting portions 3 and 4 is substantially the same. It is formed so as to extend vertically with respect to the base portion 6 so as to be equivalent.

Further, a concave groove 9 continuous in the vertical direction is formed on one smooth surface 7a of the extending portion 7 which is continuous with one surface 2a which is the surface of the slat 2. The upper edge and the lower edge of the extending portion 7 of the retaining piece 5 serve as restriction pieces 10 that close the end surfaces of the upper and lower engaging connecting portions 3 and 4 of the slat 2. The retaining pieces 5 are not attached to all the end portions 2d of each slat 2 constituting the slat curtain 1, but are attached every other stage as shown in FIG.

Next, as shown in FIG. 1, the pair of guide rails 11 provided upright on both the left and right sides of the building opening are formed in a substantially U-shaped cross-section with one side facing each other being open. Mounting grooves 12 are formed on the surfaces of the left and right vertical edges 11a of the openings of the guide rails 11 which are opposed to each other, and are provided with mohairs and the like for preventing rubbing when the slat curtain 1 moves up and down, and soundproofing. (Not shown).

Further, at the inner side of the guide rail 11, a ridge 13 is formed to continuously project in the vertical direction on one inner side surface 11b. A support strip 14 is formed so as to project on the other inner side surface 11c facing the one inner side surface 11b so as to face the convex strip 13. The gap between the convex strip 13 and the support strip 14 is set shorter than the thickness of the slat 2.

Therefore, in the structure of the shutter configured as described above, the side edge 1a of the slat curtain 1 composed of the slats 2 is inserted into the guide rail 11, but is provided at the end 2d of each slat 2. The removed retaining piece 5 is located deep inside the guide rail 11, and the recessed groove 9 formed in the extending portion 7 of the retaining piece 5 has an inner surface 11b on one side of the guide rail 11 as shown in FIG. The ridge 13 formed so as to project is slidably engaged in the same direction as the slat curtain 1 moves up and down.

As a result, as shown in FIG. 3, when the slat curtain 1 in the closed state bends due to an external force such as a strong wind, the side portion of the recessed groove 9 of the retaining piece 5 protrudes from the guide rail 11. This prevents the slat curtain 1 from being easily pulled out from the guide rail 11 by being caught by the strip 13.

Further, according to the structure of this shutter, since the retaining piece 5 fixed to the end portion 2d of the slat 2 has the same thickness shape that does not project with respect to the thickness of the slat 2, When the slat curtain 1 composed of the slats 2 is wound up to be stored, the winding diameter does not increase, and the winding operation is smooth.

Further, since the retaining piece 5 is formed to have the same thickness as the slats 2, the shape of the guide rail 11 is only slightly larger in the depth width, and the thickness is similar to that of a general guide rail. And, it fits well in the building.

Further, since the slat 2 and the guide rail 11 are in contact with each other between the groove 9 of the retaining piece 5 in the guide rail 11 and the ridge 13 in the guide rail 11. The slat 2 itself is not scratched by lifting and lowering, and the design of the slat 2 is not impaired.

Further, according to the retaining piece 5, since the restricting piece 10 is formed so as to be extended, the sliding movement between the slats 2 can be reliably prevented, and the restricting piece 10 is formed on both upper and lower edges. Since the slat 2 is formed, it is possible to block all the ends of the engaging and connecting portions of each slat 2 with a structure in which the slat 2 is attached to every other stage.

[0022]

[Effect of device]

To meet. As a result, when the slat curtain in the closed state bends due to an external force such as a strong wind, the groove of the retaining piece is caught by the ridge of the guide rail, and the slat curtain does not easily come out of the guide rail. is there.

Further, according to the structure of this shutter, since the retaining piece fixed to the end of the slat is formed in the same outer shape as the slat that does not project with respect to the thickness of the slat, the slat is stored. Therefore, when it is wound up, there is an effect that the winding diameter does not increase and it can be wound up smoothly together with the slats.

Further, according to the retaining piece having this shutter structure, since the restricting piece is formed to be extended, it is possible to reliably prevent the sliding movement between the slats in the engaging connection portion of the slats, and Since the restricting pieces are formed on both upper and lower edges, it is possible to block all the ends of the engaging and connecting portions of each slat by connecting the slats to the slats alternately. . That is, the number of parts can be reduced, and the number of man-hours for assembling work can be reduced.

Further, since the slat and the guide rail are in contact with each other between the concave groove of the retaining piece in the guide rail and the convex line in the guide rail, the slat itself can be moved up and down. It has the effects of not being scratched, not impairing the design of the slats, and of not being corroded by these scratches.
