[Industrial applications]

 The present invention relates to a building pipe shutter to be installed in an opening of a building or a house.

[Problems to be Solved by Prior Art and Invention]

 Generally, pipe shutters for this type of construction have been put to practical use for a long time for reasons that allow the inside and outside to be seen.However, conventional pipe shutters use small pipes in the through holes formed at the link ends. The pipes were connected by passing them through, and a large pipe was fitted between the left and right links so that these links would not move along the small pipes.

However, in this device, the pipe is bent by penetrating the link through hole and sliding directly around the axis, so that the pipe is inevitably scraped off by the link, and it is inevitable for long-term use. Therefore, there is a problem that the pipe is worn. To solve this problem, it has been proposed to make the pipe thicker or to make it completely solid, but doing so poses the problem of increasing the weight of the entire pipe shutter. Since it cannot be used at all, it is not possible to make the material of the pipe material highly hard, and there is a problem that it is difficult to add a decorative function as a pipe shutter.

[0004]

[Means for Solving the Problems]

 The present invention was made in view of the above circumstances to provide a building pipe shutter capable of eliminating these drawbacks, and has pin through holes formed at both ends thereof. A link member, a through hole corresponding portion that rotatably penetrates the pin through hole, a support groove formed adjacently on the left and right outer sides of the through hole corresponding portion, and a mounting formed further on the left and right outer sides of the support groove. Connection pin having a portion, a main pipe having a diameter larger than that of the connection pin, a pipe through hole through which the main pipe penetrates, a support plate having a hole into which the support groove is prevented from being fitted, and the connection plate It is characterized by being configured by an auxiliary pipe whose end is press-fitted into the pin mounting portion.

According to the present invention, the present invention makes it possible to easily install the pipe, prevent the pipe from being worn down by the link, and easily add the decoration function when necessary. .

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a shutter curtain which constitutes a pipe shutter, and the shutter curtain 1 is wound around a winding drum 2 and is guided by guide rails 3 provided on the left and right sides of the opening to perform vertical movement. All of the above are the same as conventional ones.

The shutter curtain 1 is basically assembled by using a pipe material and a link material. In the present invention, however, the link material 4, the connecting pin 5, the support plate 6, and the auxiliary pipe are used. 7 and the main pipe 8 are used, and it is as follows. That is, the pin through holes 4a are formed at both ends of the link member 4, and the connecting pin 5 is rotatably attached to the pin through holes 4a. A through hole corresponding portion 5a corresponding to the pin through hole 4a is formed in the portion, support grooves 5b for supporting a support plate 6 to be described later are formed on the left and right end portions of the portion, and auxiliary grooves are formed on the left and right end portions thereof. A mounting portion 5c is formed for press-fitting the pipe 7 and fixing it 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 in the central portion thereof, and is set to have a width that just engages with the support groove 5b so as to continue from the pipe through hole 6a. Elongated holes 6b of different sizes are respectively extended in the vertical direction. Then, through the pipe through holes 6a of the support plate 6 from both ends of the connecting pin 5 penetrating the link member 4, the connecting pin 5 and the supporting plate 6 are relatively moved so that the supporting groove 5b reaches the elongated hole 6b. After that, the end portion of the auxiliary pipe 7 is press-fitted into the connecting pin attachment portion 5c. This is done for both upper and lower elongated holes 6b, and finally the main pipe 8 is inserted into the pipe through hole 6a so that it can be assembled.

In the embodiment of the present invention configured as described above, the shutter curtain 1 is assembled by mounting the support plate with the connecting pin 5 penetrating the link material pin through hole 4a as described above. The support plate 6 is set so that the support groove 5b is located in the long hole 6b, and in this state, the end of the auxiliary pipe 7 is press-fitted into the connecting pin attachment portion 5c, and the main pipe 8 is passed through the pipe through hole 6a. The shutter curtain 1 thus assembled can be wound around the take-up drum 2 by being bent when the connecting pin 5 rotates with respect to the link member 4. Become.

As described above, the shutter curtain 1 is formed by incorporating a pipe material, but the one rotatably supported by the link material 4 is the connecting pin 5, which is the same as the conventional one. It is the connecting pin 5 that is not a pipe material and is therefore cut away by the link material 4 based on long-term use. Therefore, only the connecting pin 5 of high rigidity should be used, or it should be solid or thick. If it is formed with a pipe, it can withstand long-term use. Even in this case, since the weight of the connecting pin 5 is substantially increased, the proportion of the increase in the weight of the entire shutter curtain 1 must be thick for all pipe materials as in the conventional case. It can be suppressed to an extremely small amount compared to that, and it will not cause any problems in practical use.

Moreover, in this structure, since the auxiliary pipe 7 is retrofitted into the connecting pin 5, the auxiliary pins 7 are simultaneously fitted to the connecting pins 5 on the opposite sides of the upper and lower support plates 6, 6 as shown in FIG. Decorate the pipe shutter by, for example, making it into a casting that can create a luxurious atmosphere (of course, it does not have to be a casting and can be made of a synthetic resin material). It will also be possible to add functions, and it will have excellent marketability.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and if the support plate is adapted to be fitted in the support groove of the connecting pin in a retaining manner, it is inevitable. However, the support plate may be a simple fitting hole instead of a long hole.

[0012]

[Operation effect]

 In short, since the present invention is configured as described above, the support plate is set so that the support groove is located in the hole with the connecting pin penetrating the pin through hole, and the auxiliary pipe is set in this state. The end is press-fitted into the attachment part of the connecting pin, and the main pipe is passed through the pipe through-hole to be assembled.In the shutter curtain assembled in this way, the connecting pin is attached to the link material. It becomes a structure that bends when it is rotated. Therefore, the one that is rotatably supported by the link material is the connecting pin, which is not the pipe material as in the past, but the one that is scraped by the link material due to long-term use. Therefore, if only the connecting pin with high rigidity is used, or if it is formed with a solid or thick pipe, it will be sufficiently durable for long-term use. Even in this case, if the weight of the connecting pin is substantially increased and the weight is increased in the entire shutter curtain, all the pipe materials must be thick as in the conventional case. Compared with the above, it can be suppressed to a very small amount, and the cost up can be suppressed, so that there is no practical problem.

Moreover, the auxiliary pipe can be integrally fitted to the connecting pins on the opposite sides of the upper and lower support plates at the same time, and the decorated pipe can be used there, The decoration function can be easily added to the shutter, which makes it more marketable.
