Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an end metal structure of a building shutter slat.

[Problems to be Solved by Prior Art and Invention] In general, a plurality of slats composing a shutter curtain are interlocked with each other so as to be rotatable with each other. In this case, the slats are prevented from slipping laterally. Metal fittings are attached to both ends of the connecting part to prevent lateral displacement. By the way, in the case of a so-called weight shutter used for a relatively large opening, the weight of the shutter curtain is large, so that a suitable number of slats such as two or four slats are interlocked to connect the slatt unit. Are brought in to the site, and they are hung at the site and sequentially assembled by interlocking. Also in this case, it is necessary to prevent the lateral slippage with a metal scrap, but conventionally, as shown in FIGS. 6 and 7, the end portion of the metal scrap B previously attached is bent by an appropriate tool such as a monkey wrench to insert the thrust S. In this state, the slat S is inserted to interlock with the interlock, and then the bent end is bent back to prevent lateral displacement. Therefore, when the workability is remarkably poor and the end metal B has a large thickness, a great amount of labor may be spent on bending work using a tool, and due to material fatigue caused by bending work, the function and quality may be reduced. Problems such as deterioration occurred, and in any case, workability and quality credibility were not satisfactory.

[Means for Solving the Problems] The present invention was conceived with the object of providing a scrap metal tool for a building shutter shutter capable of eliminating these drawbacks in view of the above circumstances. , In a shutter curtain in which a plurality of slats are rotatably connected to each other by interlocking, a base fixed to the end part of the slats has its both ends blocking the outer side of the upper and lower connection parts of the slats, and the slats of the slats slid together. It is characterized in that a locking rod for preventing is slidably provided so that one of the closed upper and lower connecting portions can be opened.

Further, the present invention enables the assembling of the slatt unit on site without any bending work of the scrap metal.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, S is a general slat having interlock couplings 12 and 13 above and below a surface portion 11 which is slightly bulged outward, and a plurality of image slats S are rotated by the coupling portions 12 and 13. A shutter curtain is constructed by movably connecting them. A is a metal scrap made of a strong material, which is attached to both edges of every other one of the slats S, on which the present invention is applied. Reference numeral 1 denotes a plate-shaped base of the metal scrap A, and a pair of projecting portions 2 are formed at both ends of the base 1 so as to face each other, and a space 3 is provided therebetween. A through hole 4 through which a locking rod 5 slidably passes is formed in each of the projecting portions 2. Further, 6 is an ammunition machine which is located between both projecting portions 2 and which is fitted onto the locking rod 5, and 7 is a substantially U-shaped support body 7,
The supporting body 7 is integrally fixed to the locking rod 5 by a screw 8, one end of the bullet 6 is locked in a locking hole 7a formed in one side of the supporting body 7, and the other end is fixed. Is locked to the projecting portion 2, and the locking rod 5 is biased by the biasing force of the ammunition machine 6 so that the support body 7 is elastically pressed against the one projecting portion 2 side. The scrap metal A is assembled by fixing the base 1 to the end of the slats S. At this time, the locking rod 5
Both ends protruding from the protruding portion 2 of the
It is located at the lateral shift restriction position that blocks 2 and 13 from the side, but if the support 7 is slid against the ammunition 6 in this state, the outside of one of the connecting portions 13 is opened and the lateral shift restriction is released. Then, the connecting portion 12 of the next slat S is inserted thereinto to be incorporated into the slide, and when the slide is completed, the locking rod 5 is returned to the original state by the urging force of the ammunition 6, The outside of the connecting portion 13 is closed. The reference numeral 9 is a cover for covering a part of the space 3, and the movable range for sliding the support 7 is opened.

In the embodiment of the present invention constructed as above, first,
The assembly of the scrap metal A is performed by the through hole 4, the bullet 6,
The locking rod 5 is inserted in the order of the other through hole 4, and in this state, one end of the bullet 6 is locked in the locking hole 7a of the support 7 to fix the support 7. In this case, The support rods 7 are fixed with screws 8 while the locking rods 5 are positioned so that both projecting amounts from the base 1 are substantially equal and the bullet 6 is compressed. In this state, as shown in FIG. 2, both of the protruding amounts of the locking rod 5 are equal, and the locking rod 5 can move rightward but is restricted in movement leftward by the support 7. Then, the cover 9 is fixed by appropriate means, and the assembly of the end piece A as a single unit is completed. In this way, the bill A is stored in advance as an inventory.

Next, in order to assemble the slat unit, first, the base 1 of the end piece A is placed on both ends of the front surface 11 of the slat S so that the locking rod 5 moves in the direction of the upper coupling portion 12 of the slat S. Further, the locking rod 5 is positioned so as to contact both end faces of the slat S, and welded to half the slat S. Then, each unit is assembled into an even number of sheets (2 sheets, 4 sheets, etc.) that are easy to handle to form a slat unit, which is then carried on site.

On the other hand, at the site, the slatting unit is hung from above to be connected sequentially, but at the time of this connection, if the support 7 is slid upward, the outside of the lower connecting portion 13 is opened, so Insert the upper connecting part 12 of the slatt unit. In this case, once the next slats S are inserted, the locking rods 5 are pressed by the upper connecting portions 12 of the lower slats S, so that the support 7 can be released, and the upper and lower slats S can be released. When the insertion movement is completed to the state where the outer side surfaces of the rods coincide with each other, the locking rod 5 automatically returns to the original position by the urging force of the bullet 6 and the outer sides of the interlock connecting portions 12 and 13 of the slat S are closed. Will be.

As described above, according to the present invention, it is possible to carry out the on-site assembly by bringing in the previously assembled slatt unit, but at this time, the locking rod 5 is slid to open the outside of the connecting portion 13, In this state, the connecting portion 12 of the next slat S may be inserted, and accordingly, there is no trouble of bending the end metal A as in the conventional case, and not only the work is simplified but also the fatigue of the members is not caused. , Does not deteriorate the function.

[Effects] In summary, since the present invention is configured as described above, the locking rod is slid to move the outside of one of the connecting portions when the next slatt is assembled into the slats to which the end pieces are attached. The next slat can be inserted and connected just by opening it.
As in the past, the troublesome and complicated work of bending each end of a metal piece with a tool is completely unnecessary, which makes it extremely easy to install on site and at the same time prevents fatigue of members and reduces the shutter function. There is no.
