Abstract

(57) [Summary] [Purpose] The conventional slide cone bar requires time and labor for processing, and is therefore expensive. Further, long pipes, metal pipes, and those having both ends machined have not been possible with conventional techniques. Therefore, a new type of slide cone bar that solves these problems has been desired. [Structure] This is a completely new type of slide cone bar that solves all of the above problems by simply making holes in the ends of a thick pipe and a thin pipe and attaching a string as shown in FIG. [Effect] You can use pipes of any material such as plastic, metal, etc. The slide cone bar of the present invention can easily be 3 m or 4 m compared to the conventional extended length of about 2 m regardless of the length of the pipe. I can. Also, the attached string is completely invisible from the outside, does not spoil the aesthetic sense, and does not break. It is also convenient to carry, easy to carry and cheap. The cost is also very low and is indispensable for public works projects.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The slide cone bar is mainly used for organizing and securing people and vehicles for various road works by attaching yellow reflective tape to a black plastic pipe and attaching it to a red triangular color cone with a suspension ring. Since the length of the slide cone bar is short when it is contracted, it is convenient to transport to the road construction site, and because it slides, it can be freely attached to the color cone according to short and long distances. Therefore, it is used in many fields.

[0002]

[Prior Art]

 A conventional slide cone bar is one in which two pipes, that is, thick pipes, are gradually thinned so that two pies do not come out, like a hanging rod, or the plastic pipe is heat-processed, and in principle Like the hanging rod, the end of the thick pipe is thin and the end of the thin pipe is thick so that it will not come out.

[0003]

[Problems to be solved by the device]

 The conventional slide cone bar requires time and effort at the processing stage, resulting in higher cost, more space, and delayed delivery. Therefore, a simpler slide cone bar is required. Unlike plastic, metal pipes are not used because they do not heat-process. In addition, the length is limited, and the extended length is about 2 m, which is the limit of processing, so a longer slide cone bar is required.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has devised a slide cone bar that can easily expand and contract a plastic or metal pipe by making a hole in the end of the pipe and attaching a string. As shown in Fig. 1, by making holes in the ends of the thick and thin pipes and attaching a string, when the pipe contracted, the string was folded and when stretched, the string was stretched so that the pipe did not come out. In other words, it is a slide cone bar that allows the pipe to slide for the length of the string. Also, because the hanging ring is attached, the string cannot be seen from outside.

[0005]

[Action]

 If you have a thick pipe and a thin pipe to put in it, you can make a slide cone bar that can easily expand and contract any pipe by simply making a hole and attaching a string. Even a bar with a length of 4 m will be less than 2 m in length like the slide cone bar in Fig. 8 and can be easily transported and transported. When the pipe is contracted as shown in Fig. 1, the pimp is automatically folded, and when it is extended as shown in Fig. 2, the pimp is automatically pulled, and the slide cone bar can be freely expanded and contracted by the length of the pimp. Becomes As shown in Fig. 11, the thick pipe in the center can freely rotate and move.

【Example】

 As shown in FIG. 1, holes are formed at the positions of 3 at the ends of the thick pipe 1 and the thin pipe 2, and a string 4 is attached. As shown in Fig. 3, it is hung on the color cone by pushing the so-called hanging ring 5 into the pipe. Therefore, the string is completely invisible from the outside. Figure 1 is a figure when it is shrunk, and the string is woven. Fig. 2 shows the image when stretched to the maximum. Therefore, the string is maximally growing. As shown in FIG. 4, the thin pipe 2 is attached to the outside of the thick pipe 1, and the string 4 is attached by making a hole 3 at the end of each pipe. FIG. 5 is a view when the product is extended. Therefore, the length of the two thick pipes 1 combined is approximately equal to the length of the thin pipe 2. FIG. 6 shows an example of the construction site in which the hanging ring of 5 is attached and hooked on the color cone. Figure 7 uses a thick pipe 1, a thin pipe 2, and the thinnest pipe 6, and inserts 2 pipes from each side of 6 and 1 on both sides of the pipe 2 from both sides. 4 is attached, and FIG. 8 is a view when sliding for the longest time. Basically, it is a slide cone bar similar to that shown in FIG. FIG. 10 is a drawing when a hole is made in the end of the thin pipe 2 and a string 4 is attached, and when the thick pipe 1 is inserted from the outside, it is contracted, and FIG.

[Effects of the Invention] Regardless of the material, length and thickness of the pipe, you can easily make a slide cone bar by making a hole in the pipe and attaching a string. Since it does not require complicated processing, the cost is low and the length of the bar can be freely set up to 3m, 4m or more. In addition, even with metal pipes that could not be made up until now, it is possible to easily make slide bars by drilling holes. 1 and 2 show the most basic slide cone bar. It's about half the length of an ordinary non-stretching corn bar, so it's cheap, easy to carry, and space-saving. 4 and 5, the pipe can be extended from both sides. 7 and 8 have a short length when contracted, but since there are 3 slides, the length when expanded is about 3 times. 10 and 11, the center thick pipe can be freely moved and rotated even though it is a slide cone bar.
