Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for connecting shutter curtains in a pipe shutter installed in an opening of a building.

[Problems to be solved by the prior art and invention] Generally, the shutter curtain of this type of pipe shutter has a through hole drilled at the lower end of the upper connecting link and a through hole bored at the upper end of the lower connecting plate. A link connection structure was adopted in which the pipe material was passed through and assembled into the provided through hole, and the pipe penetration part swung. However, when assembling the shutter curtain with this product, it is necessary to penetrate the pipes sequentially from the end of the already assembled semi-finished pipe shutter, and for this reason, in the factory, at least the shutter curtain There is a problem that the assembly work area is required to be twice as large as the width of the assembly, making it impossible to assemble in a narrow space.

Therefore, as shown in Publication No. 44-30380,
A pipe material is inserted through the middle part of the connecting links that are linked together so that they can swing freely, so that the link swinging part does not become the pipe insertion part position and becomes a direct pivot point for the connecting links. There are products that can be constructed and assembled in narrow spaces that cannot be doubled. And in this one,
A pipe shutter can be assembled by previously inserting a pipe material through the connecting link material to form a pipe assembly unit, and by connecting the connecting link materials of these assembled units. However, in this case, each connecting link is connected by a pin, and the assembly work using these pins is troublesome and complicated due to the large number of pins, and the work efficiency is greatly reduced. The problem is that it is inferior to

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was created with the aim of providing a connecting structure for shutter curtains in a pipe shutter that can eliminate these drawbacks. Pipe assembly is carried out by inserting the pipe material into the pipe insertion hole formed in the middle part of the left and right wide cylindrical connecting link material, in which upper and lower connecting parts, which serve as mutually swingable link coupling means, are formed at the upper and lower ends, respectively. In addition to forming a unit, the connecting link member has a shape that is open in the left and right directions, including the upper and lower connecting parts, and extends to the upper and lower edges so that the upper and lower connecting parts can swingably engage with each other from indoor and outdoor directions. The pipe assembly unit is constructed so that the pipe assembly units can be linked together by slidingly fitting the upper and lower connecting parts, which are molded in a mold to the left and right by the width of the link, to the left and right. It is characterized by:

With this configuration, the present invention makes it possible to assemble the pipe shutter extremely easily and reliably.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a shutter curtain of a pipe shutter, and the shutter curtain 1 is wound around a winding drum 3 housed in a shutter case 2, and the winding drum 3 rotates forward and backward. Therefore, the shutter curtain 1 is designed to move up and down while being guided by the guide rail 4 to open and close the opening. There is.

That is, in this embodiment, the link material 5 is formed by cutting an extruded aluminum alloy material to an appropriate length, and is a cylindrical member that is open in the left-right direction and has an appropriate width in the left-right direction. However, this width depends on the width of the opening where the pipe shutter is used, the number of pipes,
This is arbitrarily set depending on the weight, etc. Connecting portions 7 and 8 are formed at both upper and lower end edges of the link member 5 and serve as connecting means that can swing freely by interlocking with each other. That is, the upper connecting portion 7
extends from the upper end edge of the link member 5 so as to form a curved engagement portion 7a with an opening on the indoor side in side view, and the lower connecting portion 8 is connected to the curved side extending toward the outdoor side. An engagement enlarged part 8a is formed at the tip, and the engagement part 7a is rotatably fitted into the enlarged part 8a, so that it is swingably linked from the outside of the room. The lower connecting portion 8 has an arcuate cover side 5a extending toward the outdoor side. This cover side 5a has a hanging wall shape so that the engaging portions of the upper and lower engaging portions 7a and 8a cannot be seen from the front, and also serves to prevent rainwater from entering the connecting portion. ing. moreover,
A plurality of (three in this embodiment) insertion holes 9 are provided between the upper and lower connecting portions 7 and 8 of the link material 5, through which the pipe material 6 is inserted, and a blind rivet or the like is inserted as appropriate. It is designed to be fixed by means. The link material 5 and the pipe material 6 assembled in advance in this manner constitute a pipe assembly unit, and these assembled units are connected together by connecting the link materials 5 of adjacent units together as shown in FIG. The links are arranged so as to be shifted left and right by the link width, and in this state, the upper and lower assembly units are moved relatively to the left and right, and the upper and lower connecting parts 7 and 8 are slidably fitted together to perform link connection. In the pipe assembly units connected in this way, the outer edges of the upper and lower engaging portions 7a and 8a of the link members 5 on both sides are properly cut with a tool to prevent the connected link members 5 from sliding sideways. You can take precautions to prevent it from slipping laterally, such as by caulking it.

In the embodiment of the present invention constructed as described above, the opening of the building is opened and closed by raising and lowering the shutter curtain 1 as the winding drum 3 rotates forward and backward. 1, it is sufficient to form an assembled unit in advance by inserting the pipe material 6 into the link material 5, and then connect these assembled units by linking the link materials 5. The shutter curtain 1 can be assembled even in a place where there is not a large working area twice the width of the curtain.

Moreover, the link connection between the upper and lower connecting parts 7 and 8 is
As mentioned above, the lower connecting part 8 and the upper connecting part 7 of the link material 5 of the vertically assembled unit are disposed opposite each other by being shifted left and right by the link width, and the vertically assembled unit is moved horizontally and vertically. Since the connecting parts 7 and 8 can be slidably fitted together, there is no need to use pins to link them each time as in the past, and work efficiency can be greatly improved. The shutter curtain 1 can be assembled as a completed product by simply performing crimping or the like, which is normally done in architectural shutters, to prevent the shutter curtain 1 from shifting laterally.

Furthermore, in this case, up to three pipes 6 can be inserted into the link material 5, so the number of pipes can be selected as needed. can be adjusted arbitrarily by changing the number of pipes, so that shutter curtains 1 corresponding to various opening widths can be linked with pipe materials 6 of a common diameter by simply changing the number of pipes. 5, it is possible to improve component management, greatly simplify productivity, and reduce costs. Furthermore, since the number and color of the pipes can be changed freely, the external design can be changed as desired, and the market can be expanded by changing the specifications.

In addition, since the surface of the link material 5 has an arcuate uneven shape, the contact surface between adjacent link materials 5 during winding becomes small, and therefore the link material 5 is less likely to be damaged. This can reduce the visibility of scars.

[Operations and Effects] In summary, the present invention is constructed as described above, and therefore, the shutter curtain is constructed in such a way that an assembled unit is formed in advance by inserting the pipe material into the link material, and the assembled units are connected by connecting links. It is only necessary to connect the upper and lower connecting parts of the materials by a link connection, and therefore, the shutter curtain can be assembled even in a place where there is not a large working area twice the curtain width of the shutter curtain.

Moreover, the upper and lower connecting parts of the connecting link material are open in the left and right directions, and extend to the upper and lower edges so as to swingably engage with each other from indoor and outdoor directions. Connection can be achieved by shifting the connecting link materials left and right by the link width and then sliding the upper and lower connecting parts from this state to the left and right. There is no need to link the upper and lower connecting parts together, and work efficiency can be greatly improved.
