Description

Cane handle manufacturing method and the cane handle manufactured thereby {MANUFACTURING METHOD AND KNOB STICK}

The present invention relates to a handle for more comfortable grip of the cane, and more particularly, the shape expressed on the handle of the cane is defined in the EVA foaming synthetic water support plate foamed for processing the handle with a specific color The present invention relates to a cane handle manufacturing method and a cane handle manufactured by forming a shape-shaped groove having a pattern and expressing a shape by EVA foaming synthetic resin of different colors to be inserted into the shape-shaped groove.

In general, the cane is formed in the form of a handle formed on the upper portion of the support pipe (stick), and mainly consists of a multi-stage pipe in which another small diameter pipe enters inside the support pipe for convenience of storage.

Cane composed of a multi-stage pipe as described above is used to adjust the length of the pipe (stick) according to the user's physical condition (height size).

After adjusting the length of the pipe (stick) as described above will be walking or climbing while relying on the cane along with the portable while holding the handle.

As described above, the cane that has been used for a long time varies considerably depending on the performance of the handle.

That is, when the handle is made of a hard material, the impact force generated when the stick (pipe) hits the ground is transmitted to the wrist and the shoulder through the handle as it is, so that the wrist may feel tired or stiff. It has a disadvantage.

As the grip handle that solves the problem caused by the handle is hard as described above, the grip conveyed by the hand is soft, as well as close to the palm, allowing a stable grip. To meet the requirements, a representative handle is an EVA (Ethylene Vinyl Acetate Copolymer) synthetic resin (hereinafter referred to as "EVA foaming synthetic resin") which is a copolymer resin of ethylene and vinyl acetate.

The EVA foam synthetic resin was able to meet the needs of consumers by solving the above problems at a glance because of its soft material.

While the handle using the EVA foam synthetic resin meets the needs of consumers, the design is differentiated for the purpose of differentiating from other companies' products.

The differentiation of the design is to use a variety of pigments on the surface of the handle to express a log that symbolizes the company or to express a shape that can induce a feeling to consumers, EVA foam synthetic resin The texture is not so dense that the colored color is not clearly expressed, and the colored pigment (ink) is easily peeled off by friction with the hand, making it impossible to recognize the shape of the engraved log or shape, as well as discoloration. This causes a problem of lowering the product value of the product.

In order to solve the above problems, the handle surface of the EVA foaming synthetic resin is coated to express a log or shape, but when the surface is coated, the inherent performance of the EVA foaming synthetic resin is lost. Problem is caused.

The present invention was developed in order to solve the disadvantages of the conventional cane handle as described above, the object is to make a predetermined pattern on the foam molding handle processing EVE foam molding synthetic resin support plate Eve of different colors After evacuating the EVA foam synthetic resin support plate with the EVA foamed synthetic resin plate inserted in the longitudinal direction, polishing the outer surface of the unit handle material obtained by cutting, and inserting the EVA 3 foamed product into the shape molding groove. As the handle is expressed by a synthetic resin board, not only has the work-related trouble of having to express the shape through post-work in the state where the handle is polished as in the prior art has been solved, but the shape is not a pigment. When the pigment is used, it is expressed by the color of EVA) foamable synthetic resin. It not only solves the discoloration phenomenon caused by the peeling of the pigment, but also improves consumer's confidence in the product by preventing the discoloration and improves the quality of the product, and also secures market competitiveness by differentiating it from other products. There is provided a cane handle manufacturing method and a cane handle manufactured thereby.

The manufacturing method of the present invention for achieving the above object comprises the steps of: processing the shaping groove 20 in a direction orthogonal to the length of the foam-molded EVA foamed synthetic water support plate (10);
