Hereinafter, the present invention will be described with reference to the accompanying drawings.

As mentioned above, the multi-stage cane, such as all canes, climbing or skiing, is manufactured in the same manner without distinguishing between left hand and right hand.

All of the conventional multi-stage cane is inserted into the bottom of the upper connector to the bottom of the upper connector on the basis of facing the handle portion of the cane to the sky, while rotating by rotating in a counterclockwise direction and fixed by rotating clockwise ( It is composed of a structure that acts to release and engage).

Therefore, as described above, when the user uses all the conventional multi-stage canes by rotating the counterclockwise to fix the cane, the upper connector and the lower connector are loosened from each other.

That is, for example, in the case of the climbing stick, when the walking stick user uses the walking stick with his right hand, the lower connector is supported on the ground when the climbing stick is applied to the ground while climbing or descending. It acts to fix the upper tube is applied to the rotational force in the counterclockwise direction due to the characteristics of the human body.

And if the above action is repeated, the upper connector is continuously applied to the counterclockwise rotation, and as a result, the lower connector acts the same as the clockwise rotational force acts to loosen the upper connector and the lower connector It will work.

Therefore, the present invention recognizes the above problems and in the case of the right hand cane, even if a rotational force is applied to the upper connector in a counterclockwise direction, the tightening of the top connector and the lower connector is strengthened, thereby providing a multi-stage cane that acts as a stronger binding force. It is conceived that a problem can be solved if the structure is solved.

That is, the present invention was invented from the recognition of the above-mentioned problems, and all multi-stage canes, including conventional sportswear, are manufactured separately for right-handed or left-handed use as they are not intended for right-handed or left-handed use. Since it was manufactured and provided only in one kind, it was solved by using a special connector connection structure that differs in the structure of the connector of the multi-stage cane for left-handed and right-handed ones, since it was not possible to solve the problem that is frequently solved when using the multi-stage wand. Providing a preventive staff.

The present invention relates to a detachable multi-stage wand which is easily fixed and coupled to each other by rotation and is connected to and released from the connector. Provides a multistage staple cane.

In addition, the meaning of rotating the upper connector or the lower connector in the present invention means to fix any one of the upper connector or the lower connector and to rotate the other.

The biggest technical feature of the present invention is located in the upper portion of the lower connection tube is inserted as shown in Figure 1 expansion member moving means for moving the expansion member for the function of expanding or contracting the fixed member by rotation 20 ).

Expansion member moving means in the present invention means any device or means for connecting the lower connecting pipe to the upper connecting pipe, the upper member is fixed and the linear movement of the expansion member when the lower connecting pipe is rotated.

Therefore, in the example of FIG. 1, the expansion member moving means can be seen that it is made of a screw, but is not limited to this, and includes any other device or means for converting the expansion member into a linear reciprocating motion.

That is, when the upper connector is erected and the upper part of the lower connector is inserted into the lower part of the upper connector (bottom), the expansion member is fixed when the upper connector is fixed with a hand or another tool and the lower connector is rotated. It means that the structure can move up and down which is a linear movement.

Therefore, when the lower connection tube is rotated due to the structure as described above, the expansion member moving means is rotated and thereby the expansion member is moved up and down in a linear motion. At this time, the technical feature is that the expansion member is moved when the lower tube is rotated in the clockwise or counterclockwise direction, the fixed member is expanded and contracted by the moving expansion member.

Expansion member 30 of the present invention means any device or means that is a linear reciprocating motion by the rotary motion of the expansion member moving means.

The expansion member of the present invention illustrated in FIG. 1 is a conical or upper and lower beam of upper and lower beams with a female screw-type moving inlet 31 interlocked with and engaged with an expansion member moving means of a screw type because the expansion member moving means is made of screws. Means the apparatus or means which consist of the main body 32, such as polygonal pyramid of light.

Therefore, the example of FIG. 1 described above is for explaining one extension member, and does not limit the scope of the present invention. That is, the expansion member of the present invention refers to any means or device that is interlocked with the rotational movement of the expansion member moving means to perform a linear reciprocating motion and expand or contract the fixing means by the expansion member performing the linear reciprocating motion. do.

In the present invention, the fixing member 40 supports the inner surface 12 of the upper connecting pipe 11 by pressing and supporting the upper connecting pipe and the lower connecting pipe when the volume is expanded by the linear reciprocating motion of the expansion member. When the volume of the fixing member is contracted by the linear reciprocating motion of the expansion member again, to release the pressure supporting the inner side of the upper connection part to release the upper connector and the lower connector (releasing) Means any means or device that functions.

As one example thereof, as shown in FIG. 1, the fixing member of the present invention is formed in such a manner as to surround the expansion member, and the expansion member can be inserted into the fixing member by a linear reciprocating motion. Consists of a structure in which the degree of expansion varies depending on the degree of expansion member is inserted into the fixing member.

In other words, the fixing member of the present invention means any device or means that surrounds the expansion member and the degree of expansion varies depending on the degree of expansion of the expansion member is inserted into the fixing means.

In the example of FIG. 1, the fixing member includes a contraction extension part 41 and a fixed support part 42.

The contraction extension part consists of a plurality of wings and expands when the expansion member is inserted and corresponds to a part that contracts when the extension member is pulled out, and the fixed support means a part that supports the contraction extension and can be mounted to the expansion member moving means. .

In addition, the separation preventing member 50 of the present invention serves to prevent the separation of the expansion member.

When the user of the multi-stage wand of the present invention continuously rotates the lower connection pipe in only one direction, the expansion member moving means continuously rotates in one direction, and thus the expansion member is expanded. It is possible to leave the vehicle.

Therefore, the separation preventing member has a diameter larger than the diameter of the moving member of the expansion member or larger than the diameter of the fixing support of the fixing member not to be separated from the expansion member moving means in order to prevent the expansion member from being separated. It can be achieved by adopting a configuration that can be fixed to the end 21 of the expansion member moving means by employing a fixing means such as a nut, a fixing member having.

In addition, the separation preventing member will be described in detail again, but in addition to preventing the separation of the expansion member, the fixing member is positioned at the end of the expansion member moving means to prevent the fixing member from being separated from the expansion member moving means and to fix the fixing member. It also works as a function.

In addition, the separation preventing member corresponds to a component that can be selectively employed in the present invention, and can be made in any configuration according to the user's convenience.

The biggest technical feature of this invention is demonstrated as follows.

The intermediate connector is defined as a connector that is connected to each other in the middle of the uppermost connector and the lowermost connector, as well as the lower connector for the connector located at the top and the lower connector. It is defined as the top connector.

When the right hand cane of the present invention connects the lower connector to the upper connector, it is assumed that the upper connector is set to the sky as described above to insert the lower connector into the lower upper connector as described above. When the lower connector is rotated while the connector is fixed by hand or other means, the upper connector and the lower connector will be described on the basis of the setting to allow the fixing and unwinding action of each other.

The right hand cane of the present invention has a function that the upper connector and the lower connector is coupled and fixed when the lower connector is rotated in the clockwise direction in the above standard, while the upper connector and the lower connector are connected in the counterclockwise direction. It is a big technical feature that the tube acts to loosen (disengage).

As an example of the right hand stick of the present invention, Figure 1 shows the configuration of the connection of the lower connector.

The connection part of the lower connection pipe consists of an expansion member moving means, an expansion member, and a fixing member. In particular, the expansion member moving means has a male screw shape, and has a structure that is interlocked with the female screw portion of the movement mechanism of the expansion member.

At this time, as shown in Figure 1, the expansion member moving means, the expansion member, the fixing member of the present invention is configured in the upper portion of the lower connecting tube, when the lower connecting tube rotates in the clockwise direction, the expansion member is the upper end of the lower connecting tube (10- 1) is moved in the direction, whereby the fixing member is inflated while being supported by the inner wall of the upper connecting pipe to secure the coupling of the lower connecting pipe to the upper connecting pipe.

On the contrary, when the lower connector is rotated counterclockwise, the expansion member moves in the opposite direction to the upper end of the lower connector. Accordingly, the fixing member contracts and the contact support force of the inner wall of the upper connector disappears and is released. Accordingly, the lower connector is released from the upper connector.

Therefore, this is the biggest technical feature of the present invention in order to make the above-described action, the screw direction of the expansion member moving means is made of a left-handed screw-shaped structure in which Nanasan is wound to the left as a male screw as shown in FIG.

Since the expansion member moving means is made of a left screw shape, when the lower connector is rotated in the clockwise direction, it is fixed to the upper connector, and when the lower connector is rotated in the counterclockwise direction, the upper connector is released from the connector. will be.

The expansion member moving means has a male screw shape, and has a structure in which the expansion member moving means is interlocked with the female screw portion of the moving mechanism of the expansion member.

At this time, as shown in Figure 9a, the connecting portion of the lower connecting pipe, the expansion member moving means, the expansion member, the fixing member is configured in the upper portion of the lower connecting pipe, and when the lower connecting pipe rotates in the clockwise direction, the expansion member is the top of the lower connecting pipe It moves in the opposite direction of (10-1), whereby the fixing member is inflated by the pressure input of the expansion member to be in contact with the inner wall of the upper connecting pipe and thereby to secure the coupling of the lower connecting pipe.

On the contrary, when the lower connector is rotated in the counterclockwise direction, the expansion member moves in the upper direction of the lower connector tube. Accordingly, the fixing member is contracted by the press-in release action of the expansion member, and the contact support force of the inner wall of the upper connector disappears. While the upper connector is released.

Therefore, this is the biggest technical feature of the present invention, when the above-described action, the screw direction of the expansion member moving means is made of a right-handed thread structure in which the Nanasan is wound to the right as a male screw as shown in Figure 9a.

At this time, as the expansion member is moved in the opposite direction of the upper end of the lower connection tube to expand the fixing member, the separation prevention member is a function of holding the fixing member so that the fixing member is not separated from the expansion member moving means Will be able to perform

As described above, the technical feature of the right hand multi-stage cane of the present invention is that it is made of a structure that acts to be tightened when the lower connecting portion is turned clockwise and to be released when turned counterclockwise.

Therefore, when a user using a multi-stage cane uses the right hand cane of the present invention with his right hand, the lower connector is supported on the ground and the upper connector is applied counterclockwise by the action of the user's right hand force. This action is to have the same effect as the action of fixing the upper connector and the lower connector is rotated clockwise as described above.

As a result, as the user continues to use the multi-stage wand for the right hand of the present invention, the upper and lower connectors are further tightened (combined and fixed), thereby completely preventing the upper and lower connectors from being loosened. You will see the effect.

In this way, the multi-stage cane, which is determined for use in the right hand of the present invention, becomes a functional multi-stage cane that completely prevents loosening by the aforementioned structure.

On the contrary, when the lower connector is rotated in the clockwise direction, the expansion member moves in the upper direction of the lower connector tube. Accordingly, the fixing member is contracted by releasing the pressurized member of the expansion member, and the contact bearing force of the inner wall of the upper connector is dissipated. The lower connector will loosen as it acts.

Therefore, this is the biggest technical feature of the present invention, when the operation as described above, the screw direction of the expansion member moving means is made of a left-threaded structure in which the thread is wound to the left as a male screw as shown in Figure 10a.

At this time, as the expansion member is moved in the opposite direction of the upper end of the lower connection tube to expand the fixing member, the separation prevention member is a function of holding the fixing member so that the fixing member is not separated from the expansion member moving means Will be able to perform

As described above, the left hand multi-stage cane of the present invention is that the technical features are made of a structure that is tightened when turning the bottom connection in the counterclockwise direction and released when turned clockwise.

When the user using the multi-stage cane uses the left hand cane of the present invention with the left hand, the lower connector is supported on the ground and the upper connector is applied in the clockwise direction by the action of the user's left hand force. This result shows the same effect as the action of fixing the upper connector and rotating the lower connector counterclockwise as described above.

Therefore, the left hand multi-stage cane of the present invention acts to tighten (combine and fix) the upper and lower connectors as the user continues to use them, thereby completely preventing the upper and lower connectors from being loosened. You will see the effect.
