Hiking Stick

Abstract

The present invention relates to a hiking stick, which enables the lengths of multi-stage support pipes to be quickly and simply adjusted by a simple touch and elastically supports the weight of a user when walking with the stick. The present invention provides a hiking stick ( 10 ) in which support pipes ( 11, 12, 13 ) having different diameters are combined such that the lengths of the support pipes are adjusted by adjusting means ( 30 ) and a handle ( 20 ) and a support ( 40 ) are combined to the support pipes ( 11, 12, 13 ), wherein the adjusting means ( 30 ) are configured such that: a fixing pipe ( 31 ) is coupled to the lower part of the first support pipe ( 11 ), and an operating pipe ( 32 ) is elastically supported by a spring ( 33 ) in connection with the fixing pipe ( 31 ); the second support pipe ( 12 ) having locking grooves ( 12 a ) formed on the outer surface thereof is elevated by being inserted into the first support pipe ( 11 ); a connection hole ( 31 b ) that penetrates the side of the fixing pipe ( 31 ) is perforated such that a stopper ball ( 31 a ) is inserted thereinto; when the ball ( 31 a ) is pressed on the inner diameter of the operating pipe ( 32 ), the ball ( 31 a ) is locked in the locking grooves ( 12 a ) of the second support pipe ( 12 ) whereby the second support pipe ( 12 ) is fixed to the first support pipe ( 11 ); when the operating pipe ( 32 ) is raised and the ball ( 31 a ) is located in a wide extensive groove ( 32 a ) of the operating pipe ( 32 ), the ball ( 31 a ) is separated from the locking grooves ( 12 a ) of the second support pipe ( 12 ) whereby the second support pipe ( 12 ) is elevated in the first support pipe ( 11 ); and a snap ring ( 34 ) is coupled to the fixing pipe ( 31 ), thereby preventing the separation of the operating pipe ( 32 ).

We claim: 
     
         1 . A hiking stick  10  wherein support pipes  11 ,  12  and  13  each having different diameters are engaged to each other, and the length thereof is elastically adjusted by means of an adjusting means  30 , and a handle  20  and a prop  40  are engaged to the tops and bottoms of the support pipes  11 ,  12  and  13 , comprising:
 the adjusting means  30  which includes a fixing pipe  31  engaged to bottom of the first support pipe  11 , and an operation pipe  32  engaged to the fixing pipe  31  and is elastically supported by means of a spring  33 , wherein a second support pipe  12  on an outer circumferential surface of which a plurality of engaging grooves  12   a  are formed at regular intervals, is inserted in the interior of the first support pipe  11  and ascends and descends therein, and an engaging hole  31   b  passing through its side surface is formed at bottom of the fixing pipe  31 , and a stopper ball  31   a  is inserted in the engaging hole  31   b,  and when the ball  31   a  is pressed against the inner diameter of the operation pipe  32 , the ball  31   a  is caught by the engaging groove  12   a  of the second support pipe  12 , and the second support pipe  12  is fixed in the interior of the first support pipe  11 , and the operation pipe  32  ascends, and when the ball  31   a  is positioned in a wider expansion groove  32   a  at bottom of the operation pipe  32 , the ball  31   a  disengages from the engaging groove  12   a  of the second support pipe  12 , and the second support pipe  12  freely ascends or descends in the interior of the first support pipe  11 , and a snap ring  34  is engaged to bottom of the fixing pipe  31  so as to prevent the operation pipe  32  from disengaging. 
 
     
     
         2 . The stick of  claim 1 , wherein the adjusting means  30  is engaged to bottom of the second support pipe  12 , thus adjusting the length of the third support pipe  13  inserted in the second support pipe  12 . 
     
     
         3 . The stick of  claim 1 , wherein the prop  40  comprises a first guide pipe  41  engaged to bottom of the third support pipe  13 , a second guide pipe  42  engaged to the first guide pipe  41 , a third guide pipe  43  engaged to the second guide pipe  42 , and first and second springs  44   a  and  44   b  inserted between the first and second guide pipes  41  and  42  and between the second and third guide pipes  42  and  43  for thereby elastically supporting the first guide pipe  41 , and to bottom of the third guide pipe  43 , a cemented carbide support member  45  is engaged.
