Description

Fixing device of sports stick [0001]

The present invention relates to a sports stick fixing apparatus, and more particularly, to a sports stick fixing apparatus that minimizes friction between a tapered member and a pressing member, thereby improving wear resistance and improving assembling performance. .

Commonly used sports sticks are used as climbing, fishing and skiing sticks. It is designed to be able to adjust the length of the stick, which is designed in the form of a cane, which can be used for balancing the snowy mountain or general mountain climbing, reducing the physical power consumption and making the walk more quickly and easily.

The stick is composed of two-stage or multi-stage so that it can freely adjust the length according to the user's body shape.

As a conventional technique for such a stick, it can be found in Patent Registration No. 10-0982703 entitled " Fixing Device for Variable Length Sports Stick ".

FIG. 1 is an exploded perspective view of a conventional sports stick fixing apparatus, and FIG. 2 is a cross-sectional view of a conventional sports stick fixing apparatus.

1 and 2, a conventional sports stick fixing apparatus includes an upper pipe 1 to which a handle is connected, a lower pipe 2 to be pulled out into the upper pipe 1, A sports stick comprising a fixing means (3) for fixing a lower tube (2), wherein the fixing means (3) is provided inside the lower tube (2) and has a first outer circumferential surface flat portion (3a) formed on the upper tube (1), in which the outer peripheral surface thread portion (3a-1), the outer peripheral thread portion (3a-2) and the second outer peripheral surface flat portion (3a-3) are sequentially formed; A tapered member 3b fixed to the second outer circumferential surface flat portion 3a-3 of the rod 3a and having a tapered outer surface; A support member (3c) installed inside the lower tube (2) by inserting the rod (3a) through insert injection; And a pressing member 3d mounted to surround the tapered member 3b on the outer peripheral thread portion 3a-2 of the rod 3a.

A moving nut 3e which is moved up and down along the outer peripheral surface thread portion 3a-2 of the rod 3a is provided through the insert injection in the pressing member 3d, A release preventing member 3f is provided to prevent the release of the pressing member 3d.

In the conventional sports stick fixing apparatus having the above configuration, when the length of the stick is adjusted, the upper tube 1 is held and the lower tube 2 is rotated to operate the fixing means 3, 3a of the pressing member 3d and the pressing member 3d is moved along the tapered surface of the tapered member 3b while being moved downward along the outer peripheral threaded portion 3a-2 of the pressing member 3d, The tapered member 3b and the lower tube 2 are tightly adhered to each other with the diameter of the pressing member 3d being widened by the pressing members 3d-1, 3d-1 and 3d-2.

However, the conventional fastening device for sticks for spoof is deteriorated in abrasion resistance due to abrasion due to friction between the outer surface of the tapered member 3b and the inner surface of the pressing member 3d due to long-term use and the tapered member 3b, It is not possible to reliably press the pressing portions formed in the first and second slots 3d-1 and 3d-2 of the first and second slots 3d, and thus the fixed fastening device can not withstand a strong load applied in the stick down direction.

Patent Registration No. 10-0982703 "Fixing Device of Sports Stick with Variable Length"

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 3 is an exploded perspective view of a sports stick fixing apparatus according to the present invention, FIG. 4 is a sectional view of a sports stick fixing apparatus according to the present invention, FIG. 6 is a bottom view of a pressing member of a fastening device for a sports stick according to the present invention. FIG.

2 to 6, a sports stick fixing apparatus 100 according to the present invention includes an upper tube 10, a lower tube 20 which is inserted into the upper tube 10 so as to be pulled out, And fixing means (30) for fixing the lower tube (20) to the upper tube (10).

The fixing means 30 includes a hook body 31, a tapered member 32, a pressing member 33, an escape prevention member 34 and an elastic member 35.

The tubular body 31 includes an engaging portion 31a which is coupled to the inside of the lower tube 20 by a support member 36 and a cylindrical portion 31b extending from the engaging portion 31a, The threaded portion 31c is formed.
