The present invention relates to a fastening device for the aluminum shutter connecting portion of the rolled shutter made of lightweight aluminum to connect the fixing tube to the outer side connecting to each other so that the shutter plate is not moved or separated from each other during use.

As a device for fastening the conventional aluminum shutter plate so as not to move from side to side or to be separated, as known in Utility Model Publication No. 80-1419, Publication No. 80-1519 and Publication No. 80-2255, made of aluminum The upper and lower ends of the shutter slats each have a tubular insertion part and a fitting part having different diameters, and the upper part of which has a protrusion formed at the upper part of the fitting part having the same diameter as the insertion part. It is possible to connect and assemble with a female connecting piece, protruding the anchorage on the inner side of the curved part and forming a round bar on the opposite side of the curved part, but drilling the long hole under the rounded bar corresponding to the demand for the curved part. There is a shutter plate to be fixed in the long hole, and the left and right flow prevention device of the shutter plate material that the concave groove side is formed as a round bar portion so that the inner wall surface of the concave groove is curved. Back light is known in the prior art, but all of these are interlocked in the periphery of the fastening device to prevent the detachment of the shutter plate by cutting off a part of the sliding portion that receives the most force when lifting up the shutter or lowering the wound shutter. The device is designed to prevent the friction and impact during long-term use as it weakens the rigidity and forms projections on the "c" shaped connecting pieces and pushes them into the fitting and fixing parts so that the shutter plate is not released. It is not possible to remove the closed end from which the connecting piece is separated.

In order to remove these various closed ends, the present application does not form any cutouts at the connection part of the shutter plate, and inserts the insertion plate hollow inside the tubular insertion part to insert the wedge into the wedge formed with wedges. As it is closely attached to the inner wall of the insert, it can stably support both short sides to which the shutter plate is connected, and there is no cutout at the connection part of the shutter plate, so there is no risk of damage even when used for a long time. The metal noise is not generated even during the operation. The structure is described in detail by the accompanying drawings as follows.

A cylindrical cladding part 2 is formed at one end of the shutter plate 1 formed in a wavy shape, and a cylindrical insert tube 2 'having a narrower and hollower side than the cladding part 2 is formed on the tartan.

Insert the fitting (5) in which the wedge (3) is protruded and the notch groove (4) is inserted into the insertion tube (6) in which the supporting jaw (6 ') is protruded, and the end of the mounting (5) is supported in the supporting jaw (6'). Protrude outward and the wedge (3) is hung on the end of the insertion tube (6) and then insert the insertion tube (6) in the hollow portion of the insertion tube (2 ').

Insertion tube (6) is inserted into the insertion tube (2 ') through the insertion section (2) to consistently match both ends of the insertion tube (2') and the inclusion section (2), the insertion tube (6) The insertion tube (2 ') on the opposite side is inserted into the insertion tube (6), which is inserted into the insertion tube (2') and draws the extension (5) protruding out of the support jaw (6 ') with forceps, etc. ) Is pulled separately so as not to be separated from the inside of the insertion tube (2 ') and draw the binding (5), the wedge (3) is forcibly drawn into the insertion tube (6) to secure the bend of the insertion tube (6) And thus the insertion tube 2 'is also expanded, so that the insertion tube 6 is held by the wedge 3 so as not to be detached from the insertion tube 2' and protrudes out of the supporting jaw 6 '. The long rod 5 is a structure that is removed by diffraction or drawing with a strong force to cut in the notched groove 4.

The present invention configured as described above inserts the insertion tube (2 ') by holding the insertion tube (6) through which the wedge (3) protrudes into the insertion tube (2') so as to hold the wedge (3). Can be used firmly and longly because the cutouts that weaken the) can be used and the support jaw 6 'is inserted through the insertion tube 6 into which the rod 5 is inserted at the outer end where the shutter plate 1 is connected to each other. It is designed to prevent separation of the catcher 2 so that the outer side is not only beautiful but also easy to fasten, and there is no uneven part on the inner wall of the catcher 2 and the outer side of the insertion tube 2 'so that the shutter plate 1 is wound up. It is a useful design that can be used stably and safely because it rotates smoothly when it rises or falls while it does not generate metal noise.

Claims (1)

As shown in the drawing, the fittings 5 in which the wedges 3 are protruded and the notch grooves 4 are recessed are inserted into the insertion tube 6 in which the support jaw 6 'is protruded into the ordinary catching part 2. Insert the insertion tube (6) into the inserted insertion tube (2 '), but the drawing (5) draws the wedge (3) into the insertion tube (6) as the insertion tube (6) bent and insertion tube (2') Fixing device for the aluminum shutter, which is made by expanding a part of).
