Description

The length adjustment structure of the multistage climbing stick {THE LENGTH CONTROL STRUCTURE OF MULTIPLE STICK FOR MOUNTAINEERING}

The present invention relates to a length-adjusting structure of a multi-stage cane for mountaineering, and more specifically, to a screw rod installed in a lower connection pipe, while combining a support having an inclined surface with a screw rod, the paper rod is associated with the support and can be expanded and contracted. When the upper and lower connecting pipes are turned in one direction while the pressure-sensitive body is fitted to the upper connecting pipe, the support is raised and the respective connecting pieces of the pressing body are pushed outward so that the lower connecting pipe is connected to the upper-side through the frictional force of the paper. In order to be firmly fixed to the inner surface of the pipe, the blotter body is fastened to the threaded rod through the nut body, but the blotter body and the nut body are combined to be able to flow only in the longitudinal direction. When the body load is excessively applied to the length control structure, the tack body is individually Slip flow in the sieve allows the wedge to function between the upper connector and the support so that a stronger friction force is applied to prevent the lower connector from slipping and immersing in the upper connector. It would be to pursue the reliability of.

Typically, the climbing stick has a structure in which a plurality of pipes of different diameters are interpolated so that the length can be adjusted for convenience of carrying and storage. The end of each of the connecting pipes inserted into each of the connecting pipes is rotated. An example configuration is shown in FIG. 1, in which a length adjusting structure capable of adjusting a length through a function of selectively restraining or releasing internal and external connectors is provided.

When the upper or lower connecting pipe (1) (2) is rotated in one direction while the pressure-sensitive body (4) is fitted in the state of being frictionally supported on the inner surface of the upper connecting pipe (1), the screw rod (3) through the translational movement of the screw As the upper end of the upper surface of the upper connecting pipe 1 moves through the upper side of the pressing piece 4 ', each of the pressing pieces 4' is pushed outwards, so that the lower connecting pipe 2 passes through the friction force of the holding paper 4. It is a structure that is fixed to the support but it is a closed end exposed the following problems in use.

The holding body 4 is directly connected to the screw rod 3, that is, the bearing body 4 is supported by the friction force of only two objects of the holding body 4 and the upper connecting pipe 1, and the upper and lower connecting pipes 1, 2 In the state of restraining), the friction force fluctuation of the tack member 4 is not made. Slip is generated between the outer surface of (4) and the inner surface of the upper connector (1) due to the problem that the lower connector (2) is immersed into the upper connector (1), the body supported by the stick leaned forward The balance of the body was to cause serious mountaineering accidents.

The present invention has been made in order to correct such a conventional problem,

An object of the present invention is to provide a stronger friction force by exerting the pressure-sensitive body is a wedge between the upper connection pipe and the support while the body is individually slip flow in the nut body when the body load is excessively applied to the length adjustment structure It is to provide a length control structure that can ensure the safety of the quality by enhancing the safety of use by preventing the lower connector is immersed in the upper connector so as to be immersed,

In order to achieve the above object, the present invention is to connect the support body having an inclined surface to the screw rod installed in the lower connecting pipe and at the same time to the screw rod coupled to the support body to expand and contract with the support body connected to the upper body When the upper or lower connecting pipe is rotated in one direction while being fitted to the pipe, the support is raised to push each of the tack pieces outwardly so that the lower connecting pipe is firmly fixed to the inner surface of the upper connecting pipe by the friction force of the paper. But the fastener is fastened to the screw rod through the nut body, but the tack body and the nut body is coupled to each other in such a way that it is impossible to flow independently of each other in the transverse direction, only flow in the longitudinal direction, It will be more clearly understood if it is explained in more detail based on this.

In constructing a length adjusting structure for adjusting the length by restraining or releasing each other in a state in which the upper connecting pipe 10 and the lower connecting pipe 11 are combined, the upper end of the screw rod 12 installed in the lower connecting pipe 11 A paper holding body 13 'having an inclined surface 13' at the same time, and the screw rod 12 having a plurality of paper holding pieces 14 'capable of expanding and contracting while being associated with the support 13; In a known configuration including (14);

The fastener 14 is fastened to the screw rod 12 through the nut body 20, but the tacker 14 and the nut body 20 cannot be mutually independent in the transverse direction and flow only in the longitudinal direction. It is characterized in that it is combined to enable.

※ Unexplained code in the drawing ※

(S) shows the buffer spring.

Referring to the operation of the present invention as described above is as follows.

First, in order to adjust the length of the wand, the upper or lower connecting pipe 11 is rotated so that the support 13 is moved toward the nut body 20 of the tack piece 13 ′ so that the support 13 is tacked piece 13. ') Is not pressed, that is, the upper and lower connection pipes 10, 11 is maintained so that the state of FIG.

In this state, the tack body 14 is fitted in a state having a proper friction force in the upper connecting pipe 10, the friction force is the tack body body 14 does not rotate together when the screw rod 12 rotates 14 remains intact and only the support 13 can be elevated.

In the above state, the lower connecting pipe 11 is pulled out or immersed in the upper connecting pipe 10 as appropriate, and the upper or lower connecting pipe 11 is rotated in one direction as shown in FIG. 14 is inserted into the upper connecting pipe 10 without friction by the friction force and only the screw rod 12 is moved upward through the translational movement with the nut body 20 to which the inclined surface 13 'of the support 13 is moved. Pressing each of the tack pieces 14 'outwardly as shown by the arrow so that a large friction force is generated between the outer surface of the tack piece 14' and the inner surface of the upper connecting pipe 10, the upper and lower connecting pipe 10 ( 11) is firmly bound to each other to set the length adjustment state.

Meanwhile, the cane is used in a state in which the length adjustment is completed and the upper and lower connecting pipes 10 and 11 are restrained by a constant frictional force. When an excessive force exceeding the frictional force is applied to the upper connecting pipe 10, that is, when downward movement force, that is, slip force is generated, the downward movement force of the upper connecting pipe 10 is in contact with the strong frictional force. The same downward movement force is given to 14.

Therefore, when downward movement force is applied to the tack body 14 sandwiched between the upper connecting pipe 10 and the support 13, the tack body 14 is minutely ejected from the nut body 20 and at the same time, the tack piece 14 ′. ) Is pushed outwards while contacting the inclined surface 13 'of the support piece 13 to function as a wedge, and the upper connection is made by pressing the inner surface of the upper connecting pipe 10 more strongly to generate a greater friction force. The pipe 10 is to prevent the slip.

The nut body 20 coupled to the tack member 14 is configured by forming the outer surface of the polygon or combined with the tack member 14 by forming a separate coupling projection, and mutually independent flow in the transverse direction is impossible. It can only be possible to flow in the longitudinal direction.

On the other hand, Figure 4 is to explain the principle of operation of the tack body 14 having a wedge function when the slip force is applied to the upper connecting pipe 10 as described above, the tack body 14 has a large width as shown in the figure It is not intended to flow in, but is operated as a fine movement that is difficult to grasp only with the naked eye, the drawings are intended to facilitate the understanding of the description.

In addition, the length adjustment structure of the present invention can exhibit a very excellent effect even if applied to the length adjustment structure of various articles such as a pole pole or ski pole as well as a multi-stage cane.

The present invention as described above is a structure that can be slip flow in the nut body individually, so that if the body load is excessively applied to the wand to the wedge body to exert the function of the wedge between the upper connector and the support By doing so, the lower connection pipe is not immersed into the upper connection pipe through a stronger friction force, so that the safety of use is strengthened and the quality of the reliability can be pursued.
