Description

Non-slip golf gloves having high elasticity and high air permeability}

The present invention manufactures a golf glove body with high elasticity and high breathability material, and increases friction between golf clubs and golf gloves and between golf gloves and palms, thereby minimizing or preventing problems due to slip of golf clubs occurring during a golf game. Thus, it relates to a non-slip golf glove capable of improving golf performance.

Conventional golf gloves used to enjoy golf, a kind of sport, are worn on one hand holding the handle in order for the user to stably hold the handle of the golf club and swing, and the moment the user hits the golf ball, the golf club It is worn to protect the hand or wrist from ringing and to prevent slipping of the golf club during gripping due to friction and moisture between the hand and the golf club.

In general, golf gloves are manufactured using leather (natural or artificial) or fabrics. In order to prevent slipping, golf gloves to which various anti-slip materials are applied have been developed and sold.

For example, to form a bottom protrusion (dumbbell-shaped cross-section) protruding from both sides of the bottom surface of the thumb part of a golf glove that grips the grip of a golf club (dumbbell-shaped cross section) to form a concave round surface with the convex surface of the thumb. So, it is positioned on the midline of the golf club of the thumb and correctly grips the golf club without applying excessive force to the thumb while caulking the wrist in the backswing stage (meaning the wrist is bent, but the wrist is properly bent according to the timing of the moment in the swing) There are known golf gloves that prevent overswing by accurately releasing or loosening or loosening and helping to achieve a powerful and accurate swing, and which enhances adhesion by attaching an elastic body having elasticity to one or two places on the bottom of the finger part.

In addition, a friction material is coated on the palm of the middle and ring fingers, and the knuckles and small parts in a hexagonal shape, and the friction material is mixed with silicon and germanium and silver powder to reduce the slippage of the golf club and the friction of the hand, Techniques are known to achieve a sterilizing effect.

Due to the thickness of the glove member, golf gloves have an insensitive grip unlike when holding a golf club with bare hands, so if you change golf gloves, you have to adapt until you get used to the grip or fit of the glove, making golf popular. Along with this, there is an increasing demand for golf gloves that are comfortable to wear and have an excellent anti-slip function while also having an excellent fit.

Republic of Korea Patent No. 10-0965695 (Announcement Date: 2010. 06. 15) Republic of Korea Patent Publication No. 10-2013-0074971 (published date: 2013. 07. 05)

The present invention has been devised to solve the above-described problems, and prevents the decrease in elasticity of the glove deteriorated due to frequent wearing of the golf glove, and the breathability that the sweat generated from the hand is easily radiated to the outside after wearing An excellent, non-slip pad made of a specific material is applied to the golf glove to increase the grip of the golf club when the handle is gripped and to provide a functional golf glove that can prevent slip.

A golf glove of the present invention for solving the above problems includes a palm portion surrounding the palm and a back portion of the hand covering the back of the hand, and the thumb, index finger, middle finger, ring finger, and small finger each extending to the palm portion and the back of the hand to wrap the fingers The part is integrally formed and sewn in an overlapping state, but on the opposite side of the finger part, an opening is integrally formed so that a golfer's hand can be inserted, and the palm part has a plurality of non-slip pads.

The golf glove of the present invention has excellent elasticity and breathability, and a non-slip pad is formed to prevent slip occurring during golf club swinging, and even though the non-slip pad is formed, the grip and fit are excellent. In addition, when an antifouling and waterproofing function is provided to the golf glove, it is possible to prevent deterioration of the fit due to external rainwater while maintaining excellent breathability.

At this time, each of the palm part and the back part of the hand is extended to have a finger part consisting of a thumb, index finger, middle finger, ring finger, and small finger.

Then, the oval non-slip pad prepared in Example 1-1 was attached to the inner surface and the outer surface of the palm part with an adhesive to be integrated.

Next, a non-slip golf glove was manufactured as shown in FIG. 5 by sewing and post-processing the palm part on which the non-slip pad is formed and the back part of the hand, and FIG. 6 is a photograph taken inside the palm part of the manufactured non-slip golf glove.

Preparation 2

A non-slip golf glove was manufactured in the same manner as in Preparation Example 1, but as the fabric for the palm and back of the hand, a mesh fabric formed by spray coating with the waterproof antifouling agent prepared in Example 2 to form a coating layer of the waterproof antifouling layer was used.

The evaluation of fit, air permeability and non-slip property was scored on a scale of 1 to 5, and the average values of the evaluation results are shown in Table 3 below (1 point: very bad, 2 point range: bad, 3 point range: normal, 4 point range: good, 5 Point: Very good).

In addition, the waterproof antifouling property is measured by dropping 3 drops of water droplets on the surface of the golf glove without a non-slip pad, and then measuring the time until the water droplet is absorbed and the water droplet shape disappears. Table 3 shows the average value measured 10 times. will be.
