Walking stick

Abstract

Provided is a walking stick having a pole configured by a plurality of connecting pipes. The walking stick includes: an upper connecting pipe; and a lower connecting pipe inserted into the upper connecting pipe, wherein first and second through-holes are provided in both sides of the lower connecting pipe at opposing positions to each other, first and second button members are slidably inserted into the first and the second through-holes, respectively, a spring for elastically supporting the first and the second button members in a radial direction is provided inside the first and the second button members, and third and fourth through-holes are provided in the upper connecting pipe at positions corresponding to the first and the second through-holes of the lower connecting pipe so that the first and the second button members are moved in and out through the first to the fourth through-holes.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Korean Utility Model Application No. 20-2008-0015410, filed on Nov. 19, 2008, and all the benefits accruing therefrom under 35 U.S.C. §119, the contents of which in its entirety are herein incorporated by reference.BACKGROUND[0002]1. Field[0003]This disclosure relates to a walking stick having a pole configured by connecting a plurality of connecting pipes, and more particularly, to a walking stick capable of actively managing a malfunction of a locking device and minimizing deformation of connecting pipes and the locking device by distributing impacts.[0004]2. Description of the Related Art[0005]In general, a walking stick is used by many people for climbing and sports activities or by patients for walking. The walking stick includes a pole and a handle provided to an end portion of the pole. The pole is generally configured by connecting a plurality of connection pipes so as to be folded in a longitudi...

AI Technical Summary

Benefits of technology

[0022]This disclosure provide a walking stick capable of preventing damage and deformation of connecting pipes and locking devices by increasing areas receiving impacts and distributing the impacts, and preparing for malfunctions and deformation of the locking device by compensating for a problem in which a single locking device does not operate for a single connecting portion.

[0027]In the walking stick according to the embodiment, since the two button members are provided in the opposite direction and are connected to the lower connecting pipe and the upper connecting pipe at the same time during locking, the impact is distributed and the surface pressures applied to each button member and each through hole are decreased so that the deformations of the button member and the through-hole (connecting pipe) can be minimized.

[0028]In addition, as the two locking devices (button members) complement with each other, in the case where one of them is damaged, the walking stick can be used continuously using the other one so that an emergency situation may be prevented from taking place or a user can deal with the emergency situation.

Problems solved by technology

During the use of the walking stick, there may be a case where the walking stick cannot be used anymore due to various problems.

The impact is directly transmitted to the locking device or to the connecting pipe through the locking device, and due to the impacts, many portions between the locking devices and the connecting pipes are damaged as the walking stick is used.

In addition, due to unexpected situations such as a case where a foreign material penetrates into the button or a case where the hole into which the button is inserted is deformed by a sharp impact, the operations of the spring 42 and the button 41 may be problematic, and the walking stick itself may not be used anymore.

If such a situation occurs during mountain climbing or sports activities or when a patient walks with the help of the walking stick without a carer, the user may be confronted with a dangerous situation because he / she cannot use the walking stick.

It is thought that the damage of the connecting pipe and the locking device due to the impacts is caused by the concentration of all impacts onto the single button as the single button is provided for the single connecting portion.

In addition, a problem in that the walking stick cannot be used because the locking device malfunctions and does not operate is caused by the configuration in which only the single locking device is provided for the single connecting portion.

Therefore, when a problem occurs in the locking device, there is no replacement, and the walking stick itself cannot be used.
