[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural pipe shutter to be installed in an opening of a building or a house.

[0002]

2. Description of the Related Art
This type of pipe shutter for construction has been in practical use for a long time, partly because the inside and outside can be seen.However, the conventional pipe shutter allows a small pipe to pass through a through hole drilled at the link end. Thus, the large pipe is externally fitted between the left and right links so that these links do not move along the small pipe.

However, in this case, since the pipe penetrates the link through hole and slides directly around the axis to bend, the pipe is inevitably cut off by the link, resulting in long-term use. Therefore, there is a problem that the pipe is worn. In order to solve this problem, it is suggested that the pipe be made thicker or completely solid, but doing so would increase the weight of the entire pipe shutter. Therefore, there is a problem that it is difficult to provide a decorative function as a pipe shutter, because the material of the pipe material must not be hardened.

[0004]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of providing an architectural pipe shutter capable of eliminating these disadvantages in view of the above-mentioned circumstances. A link material having a pin through hole formed therein, a through hole corresponding portion rotatably penetrating the pin through hole, a support groove formed adjacent to the left and right outer sides of the through hole corresponding portion, and Further, a connecting pin having a mounting portion formed on the left and right outer sides, a main pipe having a larger diameter than the connecting pin, a pipe through hole through which the main pipe penetrates, and a hole into which the support groove is fitted and prevented. A supporting plate and an auxiliary pipe whose end is press-fitted into the connecting pin mounting portion.

According to the present invention, with this structure, it is easy to assemble, and it is possible to prevent the pipe from being worn by the link, and it is possible to easily provide a decorative function when necessary.

[0006]

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a shutter curtain constituting a pipe shutter. The shutter curtain 1 is wound around a winding drum 2 and guided by guide rails 3 provided on the left and right sides of an opening to move up and down. Are the same as before.

The shutter curtain 1 is basically assembled by using a pipe material and a link material. In the present invention, the link material 4, the connecting pin 5, the support plate 6, the auxiliary pipe 7, It is assembled using the main pipe 8, which is as follows. That is, a pin through hole 4a is formed at both ends of the link member 4, and the connecting pin 5 is rotatably inserted into the pin through hole 4a. In addition, a through hole corresponding portion 5a corresponding to the pin through hole 4a is formed, a support groove 5b for supporting a support plate 6 described later is formed on the left and right end portions thereof, and an auxiliary pipe 7 is formed on the left and right end portion thereof. Is formed to press-fit and secure in a retaining shape. On the other hand, the support plate 6 is provided with a pipe through hole 6a for penetrating the main pipe 8 at the center, and is set to have a width just engaged with the support groove 5b so as to continue from the pipe through hole 6a. Long hole 6b of size
Extend in the vertical direction, respectively. Then, the connecting pin 5 and the supporting plate 6 are relatively moved so that the supporting groove 5b reaches the elongated hole 6b through the pipe through holes 6a of the supporting plate 6 from both ends of the connecting pin 5 penetrated through the link material 4, respectively. Thereafter, the end of the auxiliary pipe 7 is press-fitted into the connecting pin mounting portion 5c. This is performed for the upper and lower long holes 6b, and finally, the main pipe 8 can be incorporated by being penetrated through the pipe through hole 6a.

In the embodiment of the present invention constructed as described above, in order to incorporate the shutter curtain 1, as described above, the length of the support plate is set with the connecting pin 5 penetrating the link material pin through hole 4a. The support plate 6 is set so that the support groove 5b is positioned in the hole 6b. In this state, the end of the auxiliary pipe 7 is press-fitted into the connecting pin mounting portion 5c, and the main pipe 8 is assembled by passing through the pipe through hole 6a. However, the shutter curtain 1 incorporated in this way can be bent and wound around the winding drum 2 when the connecting pin 5 rotates with respect to the link member 4.

As described above, the shutter curtain 1 is formed by assembling a pipe material, but the one that is rotatably supported by the link material 4 is the connecting pin 5 as in the prior art. What is cut by the link material 4 based on long-term use, not the pipe material, is the connecting pin 5,
Therefore, if only the connecting pin 5 is made of a material having high rigidity or is made of a solid or thick pipe, it will be able to withstand long-term use. Even in this case, since the weight of the connecting pin 5 is substantially increased, the rate of increase in the weight of the entire shutter curtain 1 must be such that the entire pipe material is thick as in the related art. It can be suppressed to an extremely small amount as compared with the one, and there is no practical problem.

In this embodiment, the auxiliary pipe 7 is
Since it is to be retrofitted to the connecting pin 5, it is to be fitted simultaneously to the connecting pins 5 on the opposite sides of the upper and lower support plates 6, 6, as shown in FIG. By making it into a castable shape (of course, it is not necessary to actually make it into a cast, it can be made of a synthetic resin material), it is possible to give a decorative function to the pipe shutter, and it has excellent marketability. Become something.

It should be noted that the present invention is not limited to the above embodiment, and the support plate is not necessarily supported if the support plate is fitted in the support groove of the connecting pin in a retaining shape. Instead of the plate having a long hole, it may be a simple fitting hole.

[0012]

In summary, since the present invention is constructed as described above, the support plate is set so that the support groove is located in the hole, with the connecting pin passing through the pin through hole, and in this state, The end of the auxiliary pipe is press-fitted into the mounting portion of the connecting pin, and the main pipe is inserted through the pipe through hole. By turning with respect to the material, it is configured to be bent. Therefore, what is rotatably supported by the link material is a connecting pin,
What is cut by the link material based on long-term use, rather than pipe material as in the past, is the connecting pin.Therefore, use only high-rigidity connecting pins or solid For example, if it is formed by a thick pipe or a thick pipe, it can withstand long-term use. And even in this case, the weight of the connecting pin is increased substantially, and the rate of increase in the weight of the entire shutter curtain is reduced to the case where all pipe materials must be made thick as in the conventional case. It can be suppressed to a very small amount as compared with the above, cost increase can be suppressed, and there is no practical problem.

In addition, the auxiliary pipe can be integrally formed with the connecting pins of the upper and lower support plates at the same time on opposite sides, and a decorative one can be used therefor. The decorative function can be easily given to the shutter, and the marketability is excellent.
