Technical Field
[0001] 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.
Background Art
[0002] A hiking stick is generally configured to decrease the consumption of physical strength
in such a way to absorb about 30% of the total weight applied to user's legs, while
providing a stable hiking by maintaining balanced hiking postures when the user climbs
up or down mountain. When the user climbs down mountains, the hiking stick may effectively
absorb the impacts applied to the user's knees, so such a hiking stick is widely used
by men and women of all ages because it is regarded as one of the key hiking equipment.
[0003] The above-described hiking stick is configured in such a way that the length thereof
may be adjusted for easier carrying. More specifically, the lengths of the multistage
support pipes may be elastically adjusted by tightening or loosening the multistage
support pipes in such a way to rotate a nut type tightening member.
[0004] Since the related length adjustable hiking stick is configured to elastically adjust
the length by tightening or loosening the multistage support pipes in such a way to
rotate a thread-engaged tightening member, it takes relatively longer time to strongly
tighten or loosen the tightening member while causing complicated work. If the tightening
member is not tightly engaged, the hiking stick may not withstand strong impacts when
touching on the ground, so the support pipes may unintentionally slide into the other
support pipes, thus breaking the parts.
[0005] The hiking stick is generally made from a predetermined material and is configured
to have high durability, which are strong and high enough to prevent the hiking stick
from bending or breaking when a user touches on the ground. When the force of about
41 kg is applied for 15 seconds to a portion about 10mm away from the center of the
hiking stick, it should not be bent or broken or deformed; however many of the related
hiking sticks fail to pass the resistance test based on the materials of the hiking
sticks.
[0006] Due to the above-described problems, if the support pipes slide into the other support
pipes or the hiking stick is bent or deformed, the user may lose the center of gravity
when climbing down mountains, which results in critical accidents.

Technical Problem
[0007] Accordingly, the present invention is made in an effort to improve the above-mentioned
problems. It is an object of the present invention to provide a high quality and good
function hiking stick characterized in that the length of a hiking stick may be quickly
and easily adjusted through simple procedures, and the hiking stick may be prevented
from bending in such a way to elastically support the weight.
Solution to Problem
[0008] To achieve the above object, there is provided a hiking stick 10 wherein support
pipes 11, 12 and 13 each having different diameters are engaged to each other, and
the length is elastically adjusted by means of an adjusting unit 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 unit 30 which includes a fixing pipe 31 engaged to bottom
of the first support pipe 11, and an operation pipe 32 which is 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
12a 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 12a 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 32a at bottom of the
operation pipe 32, the ball 31 a disengages from the engaging groove 12a 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.
Advantageous effects
[0009] In the present invention, the length of the second support pipe 12 may be quickly
and easily adjusted through simple procedures of pulling the operation pie 32 of the
adjusting unit 30. When releasing the pulled operation pipe 32, the length-adjusted
first and second support pies 11 and 12 are reliably fixed, so the length adjusting
work may be simply finished while obtaining enhanced convenience when in use, which
leads to the provision of a high quality and good function hiking stick. Also, a pair
of springs formed of first and second springs 44a and 44b of the support unit 40 are
provided so as to distribute and support weight, thus stably supporting the weight
thanks to a synergic operation of the support force which balances a user's body and
the buffer power, so the center of gravity may be stably maintained, while effectively
absorbing impacts and preventing any deformation of the hiking stick, whereby safe
mountain hiking may be obtained.

Best modes for carrying out the invention
[0012] In order to accomplish the object, the preferred embodiments of the present invention
will be described with reference to the accompanying drawings.
[0013] As illustrated in Figures 1 to 4, the length of the hiking stick may be adjusted
in such a way that support pipes 11, 12 and 13 each having different diameters are
engaged, and the support pipes 11, 12 and 13 are inserted into the interiors of the
neighboring support pipes, thus contracting the length, and when they are withdrawn,
the length extends.
[0014] The support pipes 11, 12 and 13 are configured for their lengths to be adjusted by
an adjusting unit 30. A handle 20 and a prop 40 are engaged to the tops and bottoms
of the support pipes 11, 12 and 13.
[0015] The construction of the thusly constituted hiking stick 10 is a known art. The most
important feature of the present invention lies in the construction of an adjusting
unit 30 which is configured to facilitate the lengths of the support pipes to be quickly
and easily adjusted when the operation pipe 32 is simply touched.
[0016] More specifically, the adjusting unit 30 comprises a fixing pipe 31 engaged to bottom
of the first support pipe 11, and an operation pipe 32 which is engaged to the fixing
pipe 31 and is elastically supported by the spring 33.
[0017] The second support pipe 12 is inserted into the interior of the first support pipe
11 and may ascend and descend therein. A plurality of engaging grooves 12a are formed
at regular intervals on an outer circumferential surface of the second support pipe
12.
[0018] At the bottom of the fixing pipe 31, there is formed an engaging hole31b which passes
through its side surface. A stopper ball 31 a is inserted in the engaging groove 31
b.
[0019] In a state that the stopper ball 31 a is inserted in the engaging hole 31 b, when
the ball 31 a is pressed against the inner diameter of the operation pipe 32, it protrudes
in an inward direction in the engaging hole 31, so the ball 31 a is caught by the
engaging groove 12a of the second support pipe12, and the second support pipe 12 is
fixedly inserted in the interior of the first support pipe 11.
[0020] When the ball 31 a ascends in the fixing pipe 31 by pulling the operation pipe 32,
the ball 31 a is positioned in the wider expansion groove 32a at the bottom of the
operation pipe 32 and remains free, so the ball 31 a separates from the engaging groove
12a of the second support pipe 12, and the second support pipe 12 may freely ascend
or descend in the interior of the first support pipe 11.
[0021] A snap ring is engaged to the bottom of the fixing pipe 31, thus preventing the operation
pipe 32 separating and moving toward the bottom of the fixing pipe 31, and a shoulder
31 c is formed at top of the fixing pipe 31, so the operation pipe 32 may move between
the shoulder 31 c and the snap ring 34 in a state that the operation pipe 32 is elastically
supported by the spring 33.
[0022] As illustrated in Figure 3a, in the present invention, the stopper ball 31 a is engaged
to the engaging groove 12a of the second support pipe 12. In a state that the second
support pipe 12 is fixedly inserted in the interior of the first support pipe 11,
when the operation pipe 32 is pulled in an upward direction, as illustrated in Figure
3b, the ball 31 a is positioned in the wider expansion groove 32a at bottom of the
operation pipe 32 and remains free. When the operation pipe 32 is released at a predetermined
length while freely moving the second support pipe 12, the operation pipe 32 descends
by recovery force of the spring 33, and the stopper ball 31 a is pressed against the
inner diameter of the operation pipe 32 and is caught by the engaging groove 12a of
the second support pipe 12, so the length of the second support pipe 12 is adjusted
and fixed.
[0023] The length of the second support pipe 12 can be quickly and easily adjusted by a
simple procedure of pulling the operation pipe 32. When the pulled operation pipe
32 is released, the first and second support pipes 11 and 12 whose lengths have been
already adjusted may be stably fixed, so it is possible to provide a high quality
and good function hiking stick whose length may be easily adjusted, while enhancing
convenience when in use.
[0024] Also, the stopper ball 31 a, the fixing pipe 31, the operation pipe 32 and the first
and second support pipes 11 and 12 are all made from stainless steel, so once the
stopper ball 31 a is caught by the engaging groove 12a of the second support pipe
12, it is stably fixed and won't easily separate from the engaging groove 12a, which
makes sure that requirements of the resistance test may be met while substantially
supporting the weight. So, the present invention may provide a hiking stick having
a high competitiveness and good function by improving the problems encountered in
the conventional art wherein the hiking stick is inserted into the interior of the
support pipes and is bent or deformed, which causes critical accident when a user
climbs down mountains and then loses the center of gravity.
[0025] The adjusting unit 30 may be also 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. The engaging groove 13a is also formed at the third support pipe 13, so the
ball 31 a of the adjusting unit 30 may be engaged thereto.
[0026] At this time, the lengths of the second support pipe 12 and the third support pipe
13 may be together adjusted by means of two adjusting units 30 for thereby more greatly
adjusting the length of the hiking stick 10. The length of the hiking stick may be
adjusted much shorter, thus enhancing convenience when carrying the hiking stick.
[0027] The prop 40 comprises a first guide pipe 41 fixedly 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 44a
and 44b which are 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. To bottom of the third guide pipe 43, a cemented carbide
support member 45 is engaged.
[0028] To bottom of the first guide pipe 41, a snap ring 46 is engaged for thereby preventing
the second guide pipe 42 from disengaging and moving toward bottom of the first guide
pipe 41.
[0029] In the above-described construction, since the first guide pipe 41 fixedly against
the third support pipe 13 is elastically supported by means of the first and second
springs 44a and 44b, the weight applied when the hiking stick 10 is touched may be
elastically absorbed, by means of which it is possible to prevent the hiking stick
10 from bending or breaking or deforming, which results in safe hiking.
[0030] Since the two springs consisting of the first and second springs 44a and 44b are
configured to support weight in such a way to distribute the weight, the support force
maintaining a balance of a user's body and the buffer powder absorbing the impacts
synergically operate, thus implementing a good function hiking stick, so the present
invention may absorb impacts while maintaining the center of gravity by stably supporting
the weight and prevent any deformation of the hiking stick, which leads to safe hiking.

illustrative purposes and should understood in such a way that the above-described
examples are not limited by any of the details of the foregoing description, unless
otherwise specified, but rather should be construed broadly within its spirit and
