Description

Length control of climbing stick

The present invention is an improvement of the applicant's pre-registration design registration No. 1,526, which is designed to freely adjust the length of the multi-stage climbing cane, in which the support pipes having different diameters enter and exit, and maintain the adjusted state firmly. In particular, the present invention relates to a climbing handle of a climbing stick, which not only raises the bearing capacity by improving the length adjusting mechanism, but also prevents the lower pipe from flowing down from the upper pipe even when the pressing tool is not operated (opened).

Generally, the climbing stick has a handle formed on the upper part of the support pipe (stick), and is mainly composed of a multi-stage pipe in which another small diameter pipe enters and exits the support pipe for convenience of storage. .

Climbing cane consisting of a multi-stage pipe as described above is used by adjusting the length of the pipe (stick) according to the user's physical condition (height size), it is possible to use by adjusting the length of the pipe as the upper pipe It is made by the length adjustment opening installed in the upper portion of the lower pipe to be inserted.

As described above, the climbing cane length adjusting device adapted to adjust the length of the pipe (stick) has been conceived in various ways, among which, for example, the "climbing cane" registered as the applicant No. 183526 is as follows.

Registration No. 183526 of the first registration of the lower pipe fitted with the handle is equipped with a handle on the top of the lower pipe is fitted with a continuous operation of the tapered bolt and the tapered inclined bar is mounted, the inside of the pressure port is coupled to the tapered nut Grooves and tapered inclined grooves are continuously formed, and the outer four sides are formed with cutting grooves 40a extending from the top to the bottom and the bottom to the top, respectively.

The pre-registered design configured as described above simply rotates the lower pipe fitted to the upper pipe, and the upper and lower operating pipes are screwed into the pressure port, so that the tapered bolt groove and the inclined bar of the operating port are tapered nut grooves inside the pressure port. The cutting grooves are inserted into the inclined grooves at the same time, and the cutting grooves formed at the upper and lower portions of the pressing holes are opened at the same time, so that the entire pressing holes are in close contact with the inner wall of the upper pipe. More than doubled the bearing capacity, the lower pipe is inserted into the upper pipe to prevent accidents that occur.

The control mechanism in the sentence having the above advantages has a drawback that the lower pipe easily flows out of the upper pipe when there is a tolerance between the pressurizing port and the upper pipe when the pressurizing port is not operated by the operating port, thereby shortening the length. Even when storing, there is an inconvenience to set the adjusted state by operating the pressure port.

The present invention complements and improves the deficiency of the pre-registered registration No. 183526. The lower part of the cutting groove of the pressing hole extends to the cut groove, and its surface protrudes from the surface of the pressing hole so that the surface always contacts the inner surface of the upper pipe. Not only does it prevent the lower pipe from flowing down from the upper pipe even when the pressure port is not in operation, and the lower pipe can be supported more firmly with respect to the upper pipe. The purpose of the present invention is to provide a length adjusting tool for the climbing cane, which is formed to be extended to the operating tool, which simplifies the parts and improves the productivity according to the assembly production.

As shown, the length adjustment opening of the climbing cane of the present invention, the handle 11 is formed on the upper end of the upper pipe 10 of the climbing cane, the lower pipe 20 is a little smaller in diameter below the upper pipe (10) Is to be fitted.

The upper end of the lower pipe 20 is equipped with an operating port 30 is screwed into the pressure port 40, the operation 30 is tapered type inclined in the upper and lower light (上 狹 下 廣) type A tapered shoulder portion 32 is formed on the upper portion of the bolt 31 in the form of upper and lower light, and a piece 33 having a latching ring 34 is formed in succession with the shoulder portion 32.

The tapered shoulder of the inclined tapered nut 41 and the actuating tool 30 is fastened to the tapered bolt 31 of the actuating tool 30 at the center of the pressurizing tool 40 coupled to the actuating tool 30. On the tapered inclined surface 42 and the piece 33 on which the part 32 is located, a fixed annular jaw 43 is formed, in which the locking annular projection 34 is locked.

On the outside of the tapered nut 41, an upper cutoff groove 44 and a lower cutoff groove 45 are formed at right angles, respectively.

The cutting grooves 44 and 45 are evenly spread by the operation hole 30 so that the entire outer surface of the pressing hole 40 is in close contact with the inner surface of the upper pipe 10.

In addition, the pressing protrusion 46 formed to extend with the cutting groove 45 cut down is configured to be in close contact with the inner surface of the upper pipe 10 while interlocking together when the cutting groove 45 is opened.

According to the present invention configured as described above, as shown in FIG. 5a, the lower pipe 20 having the pressure port 40 installed therein is inserted into the upper pipe 10.

When the lower pipe 20 is inserted into the upper pipe 10 as described above, the pressing protrusion 46 extending from the cutting groove 45 of the pressing hole 40 is in close contact with the inner surface of the upper pipe 10. Is achieved.

As described above, the lower pipe 20 fitted to the upper pipe 10 is rotated to adjust and use the pipe (stick) length of the climbing stick.

When adjusting the length of the climbing cane, the lower pipe 20 is rotated so that the upper operating hole 30 is rotated, the tapered bolt 31 of the operating hole 30 is formed in the center of the pressing hole 40 It is rotated while being screwed to the tapered nut 41.

As described above, the tapered bolt 31 is inserted deeply into the tapered nut 41 of the pressing hole 40 and the tapered nut 41 is pressed to press the tapered nut 41 to open to the outside.
