Description

Shock Absorber for Mountaineering Multistage Cane {MULTIPLE STICK}

The present invention relates to a multi-stage cane for climbing, and in particular, to form a support tube on the lower side of the handle frame and insert a pin indentation into one of the indentation hole of the support tube after inserting the support tube formed on both sides of the moving hole inside the support tube. It penetrates the moving hole of the main pipe for easy flow, and then press-fits and secures it with the other indentation hole. It is made by attaching and attaching. It can protect the wrist joint or arm joint when the cane is placed on the ground when climbing or walking. The simpler configuration of multiple connectors that are interpolated into the underside of the prop As it can be manufactured in a variety of ways, it is possible to obtain cost savings due to the simplicity of production and the simplification of the assembly procedure. It relates to a shock absorber of the climbing multi-stage cane can be obtained by assembling the characteristic handle covers.

In general, the climbing multi-stage cane is supported by the user holding the handle by hand and holding the cane, the tip coupled to the end of the connector is in contact with the ground while supporting some of the user's weight.

However, the wand is transmitted to the handle along the respective connection tube and the impact occurs when the contact with the ground is delivered to the hand or arm of the user holding the handle.

Therefore, when the mountain climbing for a long time, the impact is accumulated on the wrist or arm, so that the wrist joint or the arm joint has a problem.

Conventional climbing multi-stage cane buffer device for solving the above problems is the pressure-sensitive body of the lowermost connector that the lower part of the upper body of the upper end of the connector is inserted into the holding tube of the plurality of connectors interpolated into the holding tube or the lowermost connector An elastic member is installed in the lower part to cushion the shock transmitted from the connecting pipe.

However, as described above, the elastic member coupled to the lower side of the pressure-sensitive body of the connecting tube wears out the outer circumferential surface of the pressure-sensitive body because it adds considerable pressure to the pressure-sensitive body being pressed by the force that opens the inner surface of the connecting tube when the load transmitted is exhausted. There was a problem that the degree is getting worse.

As described above, when the outer circumferential surface of the tack body is worn out, the inner surface of the connecting pipe cannot be squeezed, and thus the function of the stick is lost. Therefore, it has a cumbersome and inconvenient problem of frequent exchange of the tack.

In addition, the handle of the conventional climbing multi-stage cane was produced as a single body without the distinction between the handle body and the handle cover bar, if any one of the manufacturing work is defective, the disposal of the handle as a whole could not be very inefficient work. And there was also a serious problem of waste of manufacturing costs.

SUMMARY OF THE INVENTION An object of the present invention is to solve such conventional problems,

When walking the cane on the ground during climbing or walking, the load transferred to the holding tube can be buffered inside the handle to protect the wrist joint or the arm joint, and by installing a shock absorber inside the handle of the can, the lower inside of the holding tube As it is possible to manufacture a plurality of connectors inserted into the furnace with a simpler structure, it is possible to obtain cost savings due to the simplicity of production and the simplification of the assembly procedure. The handle cover can be combined and attached to provide a purpose to obtain a variety of distinctive handle covers by assembly.

The present invention to achieve the above object,

The support tube is formed under the handle frame, and the support tube is inserted into the support tube, and the support tube is inserted into the support tube. Then, the press pin is inserted into one of the support tubes. The press-fit fixed by the side indentation hole and the support between the support cap coupled to the upper portion of the holding tube and the support protrusion projected inside the handle frame, the elastic member is assembled, and attaching the handle cover to the outer peripheral surface of the support tube to achieve the object of the present invention. Can be.

In the present invention as described above, the load transmitted to the holding tube when the walking stick on the ground when climbing or walking can be buffered inside the handle has the effect of protecting the wrist joint or arm joint.

The present invention as described above, by installing a shock absorber in the handle of the cane can be manufactured in a simpler structure of a plurality of connecting pipes to be inserted into the lower side of the holding pipe because the simplicity of production and cost reduction due to the simplified assembly procedure The effect can be obtained.

The present invention as described above, the outer circumferential surface of the support tube is designed in a variety of colors or shapes can be attached by attaching the handle cover produced separately to produce a useful effect that can be obtained by assembling a variety of distinctive handle covers Have

Hereinafter, the operation of the present invention will be described.

When walking on the ground with a walking stick when climbing or walking, the impact load generated when the tip contacts the ground is transmitted to the support pipe 121 along a plurality of connecting pipes.

The support cap 113 coupled to the upper support of the support tube 121 and the support tube 121 is moved upward by the impact load transmitted to the support tube 121.

That is, the moving hole 122 formed on both sides of the support pipe 121 is guided by the pressing pins 111 press-fitted into the both side indentation holes 103 of the support tube 102, as shown in FIGS. 2 to 3. It will move upward to the position as shown.

When the support cap 113 is also moved upward by the upper movement of the support pipe 121 as described above, the elastic member 112 is supported by the support cap 113 and the handle skeleton when the shock load is transmitted to the elastic member 112. The shock load transmitted while being compressed between the support protrusions 105 of 101 is absorbed and exhausted.

Therefore, the impact load transmitted to the handle frame 101 can be minimized, thereby protecting the wrist joint or the arm joint from the impact load.

Then, when the tip falls from the ground, the support member 113 and the support member 105 of the support frame 105 of the handle frame 101 is compressed while the elastic member 112 is relaxed, and the support tube 121 in the opposite direction as described above. As shown in Fig. 3 to 2 it can be lowered to the original position.

Therefore, unlike the conventional technology in which the elastic member is attached to the connecting pipe, a shock absorber is installed inside the support pipe 102 of the handle frame 101 to minimize the wear phenomenon of the tack body and to minimize the wear of the holding pipe 121. Since a plurality of connectors inserted into the lower side can be manufactured in a simpler structure without mounting the elastic member, the cost can be reduced due to the simplicity of manufacturing and the simplification of the assembly procedure.

On the other hand, the handle cover 131 is coupled to the outer circumferential surface of the support tube 102 is attached to the handle cover 131 is produced in a separate process, such as a variety of colors or shapes, so as to be assembled can be defective during manufacturing. If only the handle cover 131 in question is to be discarded, very efficient work can be expected and manufacturing cost can be reduced and it is suitable for mass production.
