Claims
1. A climbing crutch comprising: an upper flexibly hollow tubular
section, a lower flexibly hollow tubular section, and an outer rod
with a predetermined diameter, wherein the upper tubular section
includes a first upper tubular end with a predetermined length
having outer threads formed on the first upper tubular end, and
further includes a second upper tubular end with a predetermined
length having a coupling member disposed on the second upper

formed therein; the lower tubular section includes a first lower
tubular end having a screwing segment extending from the first
lower tubular end to be screwed with the first inner threads of the
coupling member of the upper tubular section, and the lower tubular
section further includes an anti-slip portion mounted thereon; the
outer rod includes a first rod end having second inner threads
formed therein.
2. The climbing crutch as claimed in claim 1, wherein the outer rod
further includes a second rod end having a tying belt capable of
being adjusted its length mounted thereon so that a climber's hand
can hold the tying belt to prevent a climbing crutch from
slipping.
3. The climbing crutch as claimed in claim 1, wherein during the
storage of the climbing crutch, the outer threads of the upper
tubular section is rotatably removed from the second inner threads
of the outer rod, and the upper tubular section is disengaged from
the lower tubular section; thereafter, the screwing segment of the
lower tubular section is fitted into the upper tubular section, the
outer threads of the upper tubular section is screwed with the
second inner threads of the outer rod so that the lower tubular
section is limited, thereby storing the upper and the lower tubular
sections and the outer rod into a shorter crutch.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a climbing crutch that can
absorb climber's weight and vibration during climbing.
[0003] 2. Description of the Prior Art
[0004] The length of conventional climbing crutch is limited within
climber's height that can not provide enough flexibility to absorb
climber's weight and vibration during climbing.
[0005] Furthermore, the conventional climbing crutch is easy to
slip from a climber's hand because a tying belt is not to be fixed
on the climbing crutch.
[0006] Because a plurality of tubular section has to be positioned
by using fastening elements, the conventional climbing crutch can
not be stored easily, having poor support strength.
[0007] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages.
SUMMARY OF THE INVENTION
[0008] The primary object of the present invention is to provide a
climbing crutch that can absorb climber's weight and vibration
during climbing.
[0009] A Further object of the present invention is to provide a
climbing crutch that can prevent from slipping from a climber's
hand by using a tying belt.
[0010] Another object of the present invention is to provide a
climbing crutch that can be stored easily.
[0011] A climbing crutch in accordance with the present invention
comprises:
[0012] an upper flexibly hollow tubular section, a lower flexibly
hollow tubular section, and an outer rod with a predetermined
diameter, wherein
[0013] the upper tubular section includes a first upper tubular end
with a predetermined length having outer threads formed on the
first upper tubular end, and further includes a second upper
tubular end with a predetermined length having a coupling member
disposed on the second upper tubular end, the coupling member
includes first inner threads formed therein;
[0014] the lower tubular section includes a first lower tubular end
having a screwing segment extending from the first lower tubular
end to be screwed with the first inner threads of the coupling
member of the upper tubular section, and the lower tubular section
further includes an anti-slip portion mounted thereon;
[0015] the outer rod includes a first rod end having second inner
threads formed therein, and further includes a second rod end
having a tying belt capable of being adjusted its length mounted
thereon.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0023] The present invention will be clearer from the following
description when viewed together with the accompanying drawings,
which show, for purpose of illustrations only, the preferred
embodiment in accordance with the present invention.
[0024] Referring to FIGS. 1-2, a climbing crutch in accordance with
a first embodiment of the present invention comprises: an upper
flexibly hollow tubular section 1, a lower flexibly hollow tubular
section 2, and an outer rod 3 with a predetermined diameter,
wherein
[0025] the upper tubular section 1 includes a first upper tubular
end with a predetermined length having outer threads 11 formed on
the first upper tubular end, and further includes a second upper
tubular end with a predetermined length having a coupling member 12
disposed on the second upper tubular end, the coupling member 12
includes first inner threads 13 formed therein;
[0026] the lower tubular section 2 includes a first lower tubular
end having a screwing segment 21 extending from the first lower
tubular end to be screwed with the first inner threads 13 of the
coupling member 12 of the upper tubular section 1, and the lower
tubular section 2 further includes an anti-slip portion 22 mounted
thereon;
[0027] the outer rod 3 includes a first rod end having second inner
threads 31 formed therein, and further includes a second rod end
having a tying belt 32 capable of being adjusted its length mounted
thereon.
[0028] In assembly as illustrated in FIG. 3, the screwing segment
21 of the lower tubular section 2 is screwed with the first inner
threads 13 of the coupling member 12. Thereafter, the outer threads
11 of the upper tubular section 1 is screwed with the second inner
threads 31 of the outer rod 3, such that a flexible climbing crutch
4 (as shown in FIG. 4) is assembled to be used by a climber as
climbing mountain or walking on the steep road (as illustrated in
FIG. 1). It is to be noted that a climber's hand can hold the tying
belt 32 to prevent the climbing crutch 4 from slipping, and the
climbing crutch 4 can also be used to absorb climber's weight and
vibration as climbing.
[0029] Furthermore, during the storage of the climbing crutch 4 (as
shown in FIGS. 5 and 6), the outer threads 11 of the upper tubular
section 1 is rotatably removed from the second inner threads 31 of
the outer rod 3, and the upper tubular section 1 is disengaged from
the lower tubular section 2. Thereafter, the screwing segment 21 of
the lower tubular section 2 is fitted into the upper tubular
section 1. The outer threads 11 of the upper tubular section 1 is
screwed with the second inner threads 31 of the outer rod 3 so that
the lower tubular section 2 is limited, thereby storing the upper
and the lower tubular sections 1, 2 and the outer rod 3 into a
shorter crutch (as illustrated in FIG. 7).
[0030] While we have shown and described various embodiments in
accordance with the present invention, it is clear to those skilled
in the art that further embodiments may be made without departing
from the scope of the present invention.
