Description

[0001] The present invention relates to a method for producing a stick knob,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for manufacturing a stick handle and a stick handle manufactured by the method, and more particularly to a method for manufacturing a stick handle, To a stick grip.

Generally, the mountain climbing stick is composed of a pipe portion whose lower portion is in close contact with the ground and a handle which is mounted on the upper portion of the pipe portion. The pipe section is composed of a multi-stage pipe which can be expanded and shrunk to facilitate storage.

In addition, the climbing stick constructed in this manner has a remarkable difference in feeling depending on the performance of the handle.

Hereinafter, an example of a conventional stick handle is described in Korean Patent Registration No. 880151 filed by the present applicant for a patent and registered as "a cane handle manufacturing method and a cane handle manufactured thereby".

First, a conventional method for manufacturing a cane handle includes: machining a shape forming groove in a direction orthogonal to a length of a foamed molded EVA foam synthetic resin disk; (EVA) foamable synthetic resin plate (10), which has a width corresponding to the width of the shape molding groove, is assembled by sandwiching and stabilizing the EVA foamable synthetic resin sheet; (EN) A method of manufacturing an EVA foamed synthetic resin sheet, comprising: (a) cutting an EVA foamed synthetic resin disk having a foamed synthetic resin plate assembled with an EVA foil for longitudinal shaping into a unit handle material; A step of machining the outer shape of the handle by polishing the outer surface of the rotating unit knob material by rotating both ends of the cut knife material formed by the cutting with the processing machine; And a step of drilling a fastening hole so that the handle having the outer shape formed by polishing can be mounted on the stick.

And the cane handle manufactured by the above method is a can handle having an outer surface processed so as to feel a comfortable grip feeling when gripped by a hand, and it is easy to shape the handle formed by EVA foam synthetic resin disk The EVA foam synthetic resin plate is assembled in the shape forming groove to be shaped so as to be expressed.

However, in the case of manufacturing the handle through the conventional knob manufacturing method, the shape molding groove machined on the original EVA foam synthetic resin plate is molded, and then the EVA foam synthetic resin plate for shaping is assembled (EVA) foaming synthetic resin sheet is thin, the EVA foaming synthetic resin sheet tends to be easily torn easily in the process of forming the handle. I had a problem.

In addition, in the case of manufacturing the handle through the conventional knob manufacturing method, when the space between the shape forming grooves is small in the process of forming the shape molding grooves on the EVA foam synthetic resin disk, So that there is a problem that the material is lost in manufacturing the handle.

Further, in manufacturing the handle through the conventional handle manufacturing method, it is necessary to further carry out a process of drilling a fastening hole for mounting the stick inside the handle after the outer shape of the handle is processed, thereby lowering the productivity of the stick handle I also had a problem.
