Abstract

(57) [Abstract] [Problem] To provide a mountain climbing stick in which a mountaineer can adjust the length so that the mountaineer can easily use it. SOLUTION: A stick main body 1 is composed of an upper pipe 2 and a lower pipe 3 which are separated from each other and are inserted into the inside of the other in a vertically movable manner, and a stick main body 1 is formed on an outer peripheral portion of the upper pipe 2 or the lower pipe 3. The adjusting screw 4 is screwed on and is attached to the outer peripheral portion of the pipe having a taper shape and having a smaller outer diameter so as to be vertically movable, and is housed inside the adjusting screw 4 so that the adjusting screw 4 is tightened. From the end on the smaller outer diameter side, it moves in the direction of press fitting between the upper pipe 2 and the lower pipe 3 to fix them, and conversely, by loosening the adjusting screw 4, the upper pipe 2 and the lower pipe 3 are The connector 5 is characterized in that it is provided with a connector 5 that moves in the direction of coming out of the space and makes both of them free.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a climbing stick.

[0002]

[Prior art]

 In recent years, the number of middle-aged and elderly people who climb for health is increasing, and these climbers often carry walking sticks. However, it was difficult for the mountaineer to obtain a stick having a suitable length that suits his or her height.

[0003]

[Problems to be solved by the invention]

 Therefore, an object of the present invention is to provide a mountain climbing stick in which a mountaineer can adjust the length to be easy to use.

[0004]

[Means for Solving the Problems]

 The above object is according to the present invention, that is, the stick main body 1 is constituted by the upper pipe 2 and the lower pipe 3 which are separated from each other and inserted into the inside of the other in a vertically movable manner. An adjusting screw 4 is screwed onto the outer peripheral portion of the lower pipe 3, and is attached to the outer peripheral portion of the pipe having a taper shape and a smaller outer diameter so as to be vertically movable and is housed inside the adjusting screw 4. Tighten the adjusting screw 4 to move it from the end with the smaller outer diameter to the direction of press fitting between the upper pipe 2 and the lower pipe 3 to fix them, and loosen the adjusting screw 4 conversely. This can be achieved by a mountain climbing stick that is provided with a connector 5 which is moved between the upper pipe 2 and the lower pipe 3 by an operation so as to be free from each other.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, in FIG. 1, reference numeral 1 is a stick main body, and the stick main body 1 is composed of an upper pipe 2 and a lower pipe 3, and the upper pipe 2 and the lower pipe 3 are just connected inside the adjusting screw 4. It

As shown in FIG. 2, the outer diameter of the upper pipe 2 is larger than that of the lower pipe 3, the outer diameter of the lower pipe 3 is smaller than the inner diameter of the upper pipe 2, and the upper end portion of the lower pipe 3 is the upper pipe 2. Inserted inside. The adjusting screw 4 has a female screw 6 on its inner surface, and the female screw 6 is screwed to a male screw 7 formed on the outer surface of the lower end of the upper pipe 2. A connector 5 is housed inside the adjusting screw 4. The connector 5 is a tapered pipe body having a small outer diameter on the upper end side and a large outer diameter on the lower end side. The connector 5 is attached to the outer peripheral portion of the lower pipe 3, and its upper end side is inserted into the upper pipe 2. Further, the lower end portion thereof is supported by the inner shoulder portion 8 of the adjusting screw 4. It should be noted that the connector 5 is provided with vertical cuts 9 at a plurality of positions in the circumferential direction of the lower half portion so that the lower half portion has a spring property and is elastically deformable in the radial direction.

As shown in FIG. 3, when the adjusting screw 4 is tightened to raise the adjusting screw 4 relative to the upper pipe 2, the connector 5 is pushed up by the inner shoulder 8 of the adjusting screw 4. The connector 5 is press-fitted deeply between the upper pipe 2 and the lower pipe 3 like a wedge to fix the upper pipe 2 and the lower pipe 3 by friction.

Next, when the adjusting screw 4 is loosened and the adjusting screw 4 is lowered with respect to the upper pipe 2, the connector 5 is also lowered accordingly and the state shown in FIG. Therefore, the fixed state of the upper pipe 2 and the lower pipe 3 is released, and the two become free from each other. Therefore, by moving the lower pipe 3 in the vertical direction with respect to the upper pipe 2 in this state, the entire length of the stick main body 1 can be expanded and contracted and adjusted to an appropriate length. Then, when the adjusting screw 4 is tightened again, the state can be fixed as described above.

[0009]

[Effect of the invention]

 The mountain climbing stick of the present invention is as described above, and the entire length of the walking stick main body can be expanded and contracted by a simple operation of tightening or loosening the adjusting screw 4, so that the mountain climber can adjust the length to a comfortable one. The effect is that you can do it. Moreover, since only the adjusting pipe 4 and the connector are required in addition to the upper pipe and the lower pipe that form the main body of the stick, it is possible to minimize the increase in the number of parts and avoid the cost increase.

Claims (1)

[Utility model registration claims] 1. A stick main body 1 is composed of an upper pipe 2 and a lower pipe 3 which are separated from each other and are inserted into the inside of the other so as to be vertically movable, and an outer peripheral portion of the upper pipe 2 or the lower pipe 3. The adjusting screw 4 is screwed onto the pipe, and is attached to the outer peripheral portion of the pipe having a smaller outer diameter so as to be vertically movable, and is housed inside the adjusting screw 4 to tighten the adjusting screw 4. To move between the ends on the smaller outer diameter side in a direction of press fitting between the upper pipe 2 and the lower pipe 3 to fix them, and conversely, by loosening the adjusting screw 4, the upper pipe 2 and the lower pipe 3 A mountain climbing stick, which is provided with a connector 5 which moves in a direction of coming out of the space and makes the both free.
