Claims:
What is claimed is:

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 tubular end, the coupling member includes first inner threads 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

1. Field of the Invention

The present invention relates to a climbing crutch that can absorb climber's weight and vibration during climbing.

2. Description of the Prior Art

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.

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.

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.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a climbing crutch that can absorb climber's weight and vibration during climbing.

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.

Another object of the present invention is to provide a climbing crutch that can be stored easily.

A climbing crutch in accordance with the present invention comprises:

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 tubular end, the coupling member includes first inner threads 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, 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

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.

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

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;

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;

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.

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.

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).

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.
