DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention stores the door body such as roll-up or lateral pulling shutter is used in the opening of such a building, but about the shutter case.

[0002]

2. Description of the Related Art In this type of shutter case, a shutter winding portion is blindfolded to prevent rainwater and dust.
A metal plate molded into a box shape has been used, but when the opening of the building becomes large, the size of the metal plate is limited, so the metal plate must be connected at the middle part and used. However, the construction required a great deal of time and labor, and was accompanied by a remarkable decrease in aesthetic appearance. The applicant for the patent is:
In view of such circumstances, using a plurality of slats made of aluminum molded material having a male joint and a female joint already formed at the side end, a female joint of one adjacent slat and a male joint of the other slat are used. A shutter case fitted and fixed in a box shape was proposed (Japanese Utility Model Publication No. 63-46627).

[0003]

However, in such a box-shaped shutter case in which a male joint and a female joint of adjacent slats are fitted, as shown in FIGS. Using a plurality of slats made of aluminum molded material forming a mold joint and a female joint,
Simply, the female joint of one adjacent slat and the male joint of the other slat are fitted and fixed in a box shape, and a gap is created between the male and female joints. There is a problem that occurs, after fitting the male and female joints of the slat on site,
It has been necessary to caulk the fitting position between the male joint and the female joint.

[0004]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies in order to solve such problems, and as a result, have been made of an aluminum molded material having a male joint and a female joint formed at the side end. a plurality of slats, fitted male joint female fitting and the other slats of the adjacent one of the slats
When constructing a shutter case with a box shape,
The male joint is formed with a curved convex part and an engagement ridge, and the female joint is formed.
Form a curved concave part and bent tip on the hand,
A concave groove is formed in the concave part, and a part of the string-like elastic body is curved
Into the concave groove so that it protrudes into
Press the curved convex part against the string-like elastic body to form the curved concave part of the female joint.
To the male part, bending the engaging ridge of the male joint into the female joint
It has been found that the occurrence of rain leakage can be completely prevented by an extremely simple assembling operation by locking to the shape-like tip , and the present invention has been completed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1, 2 and 3 show an example of a slat 3, 3,... Made of an aluminum molded material of the present invention and a connection structure thereof. A concave groove 6 is formed in the curved concave portion 4 of the female joint 1 in which the convex portion 5 is fitted, and a part of the string-like elastic body 7 is projected from the concave concave groove 4 in the concave groove 6 of the female joint 1. The string-like elastic body 7 is pressed between the curved convex portion 5 of the male joint 2 and the curved concave portion 4 of the female joint 1 over the entire length of the slat. An engagement ridge 8 is formed on the inner side of the male joint 2. When the male joint and the female joint of the adjacent slats are fitted, the engagement ridge 8 of the male joint 2 is formed. Abuts on the bent end of the female joint 1 and is locked.

As a string-like elastic body suitable for carrying out the present invention, a waterproof rubber is typically given. FIGS. 4 and 5 show an example of a shutter device suitable for carrying out the present invention, in which a female joint 1 and a male joint 2 are provided at side end portions.
Are fitted with a plurality of slats 3, 3,... Made of an aluminum molding material having an L shape and fixed in a box shape along fixed frames 10, 10,. is there. In the figure, 11 is a side panel made of an aluminum molding material, 12 is a fixed support, and 13 is a shutter door.

When fixing the slats 3, 3,... To the fixed frame 10, the female joint 1 of the slat 3 is screwed to the fixed frame, and the string-shaped elastic body 7 is fully inserted into the concave groove 6 of the female joint. Insert over. At this time, knots should be formed at both ends of the string-like elastic body 7 to restrict the movement of the recessed groove 6 in the longitudinal direction, and then the string-like elastic body 7 is inserted into the recessed groove 6 with a slight tension in the longitudinal direction. The male joint 2 of the slat adjacent thereto is inserted obliquely from above, and both slats to be connected while pressing the string-like elastic body 7 are arranged on the same surface. Such operations are repeated, and the slat 3 and the corner molding material 9 are combined in the corner portion to form a box.

[0008]

According to the present invention, there is provided a shutter case using a slat made of an aluminum molded material having a male joint and a female joint, wherein the curved convex portion of the male joint fits into the curved concave portion of the female joint. And a string-like elastic body is inserted into the concave groove formed in the curved concave portion of the female joint, and the curved convex portion of the male joint and the female joint are interposed between the curved concave portions. Even when long slats are used, the fittings between the female and male joints of the slats maintain a perfect watertight structure and prevent rain leakage for a long time even when long slats are used. can do. In addition, in the assembly of these slats, a string-like elastic body is used and inserted into the concave groove formed in the curved concave portion of the female joint, so that the on-site assembling work is greatly simplified. Is enormous.
