Grip for billiard cue

The present invention relates to a grip for a billiard cue.

In detail, the present invention prevents the cue from being pushed backward in the hand holding the grip by the repulsive force generated when the cue and the billiard ball collide when hitting the ball with the cue in a billiard game, and is mounted on the hand holding the grip and the cue It relates to a grip for billiard cues designed to improve the player's performance by proposing the shape of the protruding pattern on the grip surface so that the cross-sectional shape of the grip is matched as much as possible to provide a stable grip.

In addition, the present invention optimizes the composition of rubber and additives for manufacturing the grip to provide ideal elasticity when holding the grip strongly with the hand during the act of shooting, and when the billiard ball is hit by the billiard cue, the cue moves backward from the hand. It relates to a grip for a billiard cue which can further improve the player's performance by improving the frictional force to prevent it from being pushed.

The game of billiards is to score a score by hitting a billiard ball with a cue on a standardized rectangular table and putting a specific billiard ball into a pocket formed on the table, or by hitting several billiard balls with the hit billiard ball. As is well known, there are several game methods such as , 3-cushion, and balk lines.

In such a billiard game, the cue for hitting the ball is based on a rod of considerable length, and maintains a tapered shape that becomes thinner toward the end in order to facilitate transmission of the force to strike the ball. and the lower end is configured to be coupled.

In particular, most players use a grip made of rubber or synthetic resin mixed with rubber on the handle to hold the cue. This is used to prevent the cue from being pushed backwards from the hand holding the cue due to the repulsive force, which weakens the force transmission.

Republic of Korea Patent Registration No. 10-2010792 (Grip for Billiard Cue, hereinafter referred to as Prior Invention) describes that a grip is mounted on the handle of the cue, and when a player takes a shot while holding the grip and hitting the cue with a billiard ball, the grip is A configuration to prevent slipping from the player's hand as much as possible is suggested.

The grip for billiard cues of the prior invention is "a body made of rubber or soft synthetic resin formed in a cylindrical shape into which the handle of the cue is inserted, and the outer circumferential surface of the body is fixedly installed by an adhesive printing method and a three-dimensional pattern is formed. , in a state where the patterned silkscreen transfer paper is attached to the outer circumferential surface of the main body, liquid or gel silicone is repeatedly applied several times to a certain thickness, then the silkscreen transfer paper is removed and dried to form a form that is fixed to the main body and a non-slip layer made of a silicone material.

In the grip for billiard cue of the prior invention, three-dimensional patterns to prevent slipping in the hand are formed in various patterns. In particular, when three-dimensional patterns are specified, it is suggested that they are formed in a grid shape in which horizontal and vertical lines intersect.

At this time, the formation of various patterns of unspecified three-dimensional patterns is mainly considered in terms of design giving an aesthetic feeling. When a shot is made, the player's hand is pushed in the oblique direction where the horizontal and vertical lines intersect, which exposes a problem in that the hitting force that must be transmitted from the cue to the billiard ball is reduced.

The present invention was invented to solve the above problems.

Accordingly, the present invention prevents the cue from being pushed backwards in the hand holding the grip by the repulsive force generated when the cue and the billiard ball collide when hitting the ball with the cue in a billiard game, and the hand holding the grip and the cue mounted on the cue The purpose of this is to provide a grip for billiard cues that can improve the player's performance by proposing the shape of the protruding pattern on the grip surface so that the cross-sectional shape of the grip matches as much as possible to provide a stable grip.

In addition, the present invention optimizes the composition of rubber and additives for manufacturing the grip to provide ideal elasticity when holding the grip strongly with the hand during the act of shooting, and when the billiard ball is hit by the billiard cue, the cue moves backward from the hand. It is another object of the present invention to provide a grip for a billiard cue so as to further improve a player's performance by improving friction to prevent it from being pushed.

In order to achieve the above object, the present invention has the following configuration.

The present invention relates to a grip for billiard cues coupled to a handle of a billiard cue and having a protruding pattern formed on an outer surface thereof to provide frictional force with a player's hand holding the billiard cue, wherein the protruding pattern is a grip body coupled to the handle. A vertical pattern protruding from the surface of the , formed protruding from a plurality of points divided at equal radial angles and formed long in the longitudinal direction, and a horizontal pattern protruding between the vertical patterns and arranged at equal intervals along the longitudinal direction A grip for billiard cues comprising a.

Here, the vertical pattern is formed to protrude from 6 to 8 points in the radial direction so that at least one vertical pattern is in contact with the bent point of the finger and the palm inside the hand rolled up to grab the grip.

In addition, the protruding pattern has a "-"-shaped horizontal pattern in which both sides do not interfere with the vertical pattern between the vertical patterns, and the vertical pattern and the horizontal pattern are formed by connecting both ends of the horizontal pattern to the vertical pattern. +" form, the vertical pattern and the horizontal pattern are formed in a "+" form, and the vertical pattern is formed on both sides of the "+" so that the ends of the horizontal pattern are not interfered. do.

In particular, in the protruding pattern, the vertical and horizontal patterns are formed to protrude to a height of 0.2 to 1 mm, and the horizontal patterns are formed by setting the distance between each other to be between 10 and 20 mm corresponding to the distance between the fingers of the player.

In order to achieve the above other object, the present invention has the following configuration.

In the present invention, the grip is natural rubber (NR) 74 to 76% by weight, NBR (Nitrile-Butadiene Rubber; nitrile-butadiene rubber) 14 to 16% by weight, vulcanizing agent 2 to 4% by weight, filler 3 to 5% by weight %, and 2 to 4% by weight of additives are mixed.

As described above, the present invention prevents the billiard cue from being pushed out of the player's hand when the billiard cue hits the billiard ball by the horizontal pattern, so that the striking force transmitted to the billiard ball through the billiard cue is transmitted with high efficiency. .

In addition, the present invention allows the hand holding the grip by the vertical pattern to be in contact with the grip as much as possible to obtain a stable grip, and at the same time to prevent a phenomenon such as the billiard cue from spinning in the hand to deliver striking force with greater efficiency This has the effect of improving the performance of billiard players.

On the other hand, the present invention has the effect of further improving the player's performance by optimizing the mixing composition ratio of natural rubber and synthetic rubber to have excellent elasticity for shooting and excellent friction with the hand when hitting a billiard ball. .

An embodiment of the present invention as described above will be described in detail with reference to the accompanying drawings.

1 is an exemplary view of a grip mounted on a billiard cue, FIG. 2 is a front view of the grip for a billiard cue according to the present invention, FIG. 3 is a plan view of a grip for a billiard cue according to the present invention, and FIGS. 4A to 4C are the present invention It is an exemplary diagram of the protrusion pattern of the grip for billiard cue by

Referring to the drawings, the grip for a billiard cue (hereinafter, the grip) according to the present invention includes a grip body 11 that is fitted into the handle 2 of the billiard cue 1 to provide frictional force with the hand, and the grip body 11 ), a protrusion pattern 20 is formed on the outer surface of the billiard cue 1 to prevent the player's hand from coming in contact with the billiard ball from being pushed when hitting the billiard ball.

The grip body 11 maintains considerable elasticity and strength by mixing NR (Natural Rubber) and NBR (Nitrile-Butadiene Rubber) to be described later, and basically has a circular cross section by extrusion or injection. It is manufactured in the form of a pipe with

The protrusion pattern (20) is formed of a vertical pattern (21) formed in the longitudinal direction of the grip body (11) and a horizontal pattern (22) formed to be perpendicular to the vertical pattern (21), and the vertical pattern (21) and the horizontal pattern 22 are formed integrally protruding from the grip body 11 .

The vertical pattern 21 is formed to protrude at a plurality of points divided at radial equal angles based on the cross section of the grip body 11 . Here, the vertical pattern 21 is formed to protrude at 6 to 8 radial points (60° to 45° equal intervals) (in the figure, 8 points to protrude), which is the inside of the hand rolled to hold the grip 10 . It is a configuration of a shape corresponding to the bent point of the finger and the palm (about a hexagonal shape by the joint of the hand).

That is, the vertical pattern 21 formed at the 6 to 8 points maintains the cross-sectional shape of the grip to approximately 6 to 8 angles, so that the grip 10 is placed on the outer surface of the grip 10 by the fingers of the hand and the skin of the palm. In particular, the minimum condition for maximally contacting the skin of the fingers and palms with the outer surface of the grip 10 is at least one vertical pattern ( 21) is to be in contact with each other.

For reference, the act of contacting as if at least one vertical pattern 21 is inserted at the bent joint point of the finger and palm is any one of the bent points of the finger or palm joint by the player due to the player's habit of gripping. The vertical pattern 21 may be brought into contact with the point.

The horizontal patterns 22 are formed to protrude between the intervals of the vertical patterns 21 and are arranged in a plurality at equal intervals along the longitudinal direction. Here, the horizontal pattern 22 is set such that the distance between each other is such that the player's fingers can contact the outer surface of the grip body 11 as a whole between the gaps, which is 10 to 20 considering the thickness of an average person's finger. It is preferable to set it to keep the spacing between mm.

At this time, the interval between the horizontal patterns 22 is formed in a form in which the fingers of the players holding the grip 10 are gathered, and it is preferable to set it so as not to exceed a maximum of 20 mm. It is possible to manufacture products of various specifications according to the spacing of

On the other hand, the protrusion pattern 20 may be formed in various forms as in FIGS. 4A to 4B within the configuration in which the vertical pattern 21 and the horizontal pattern 22 are described above.

In FIG. 4A , the horizontal fringes 22 are formed in a “-” shape in which both sides of the vertical fringes 21 do not interfere with the vertical fringes 21 . This provides convenience when designing a mold for extrusion or injection since the vertical pattern 21 and the horizontal pattern 22 are formed in the simplest form.

In FIG. 4B , both ends of the horizontal pattern 22 are connected to the vertical pattern 21 so that the vertical pattern 21 and the horizontal pattern 22 are formed in a “+” shape, respectively. This causes the protrusion pattern 20 to be formed even between the gap between the vertical pattern 21 and the horizontal pattern 22 in the configuration of FIG. 4A. At this time, the intersection point of the vertical pattern 21 and the horizontal pattern 22 is By forming a round, it provides a softer grip feeling when the protruding pattern 20 is in contact.

4C shows the vertical pattern 21 and the horizontal pattern 22 are formed in a “+” shape, and the vertical pattern 21 is formed on both sides of the “+” so that the ends of the horizontal pattern 22 do not interfere with each other. l" shape. This is so that when the player touches the bent joint point of the finger and palm as if at least one vertical pattern 21 is fitted, select a more convenient point to hold the grip 10 when gripping the grip 10. did it

In the configuration of the vertical pattern 21 and the horizontal pattern 22, these protruding patterns 20 are formed to protrude from the outer surface of the grip body 11 to a height of 0.2 to 1 mm. This is, when the protruding pattern 20 is formed to be less than 0.2 mm, a phenomenon occurs that the billiard cue 1 is slightly pushed from the hand when hitting the billiard ball, and when the protruding pattern 20 is formed in excess of 1 mm, the protruding pattern 20 is formed. The height is excessively high, and the hand pain of the player is generated due to waste of raw materials and excessive protrusion height when manufacturing the grip 10 .

In addition, the vertical pattern 21 and the horizontal pattern 22 have a basic cross-sectional shape of a semicircle, and may be formed in an elliptical or triangular or more polygonal shape to provide a variety of gripping sensations.

In particular, in the drawings of this embodiment, the vertical pattern 21 is exemplified in a form that protrudes higher than the horizontal pattern 22, but the height of the vertical pattern 21 and the horizontal pattern 22 is the same or the horizontal pattern 22 is vertical. It may be formed to protrude higher than the pattern 21 .

On the other hand, in the present invention, the grip 10 is manufactured by mixing natural rubber and NBR as described above. As described above, a vulcanizing agent that causes a chemical reaction in the compounding rubber for mixing of natural rubber and NBR to change into elastic rubber. It is formulated by adding additives such as anti-aging/reinforcing/extending filler, mixing accelerator/rubber oil/colorant/pigment.

Specifically, the grip 10 includes 74 to 76% by weight of natural rubber (NR), 14 to 16% by weight of NBR (Nitrile-Butadiene Rubber; nitrile-butadiene rubber), 2 to 4% by weight of vulcanizing agent, and 3% by weight of filler. ~ 5% by weight, and 2 to 4% by weight of the additive composition is mixed.

Here, the natural rubber can obtain high elasticity and friction, while the player holds the grip for a considerable amount of time and plays a billiard game, so it has low thermal deformation due to body temperature and low corrosion resistance due to sweat. will do

In the composition of the grip 10, when the natural rubber is less than 74% by weight and the NBR is relatively more than 16% by weight, it is difficult to obtain the desired elastic force and frictional force of the grip 10, and the natural rubber exceeds 76% by weight, and Relatively, when the NBR is less than 14% by weight, the grip 10 has excellent elasticity and friction, but a phenomenon such as easily deformed or faded by the player's body temperature and sweat, natural air and ultraviolet rays, etc. occurs.

Therefore, the grip 10 for billiard cues manufactured by the composition as described above maintains excellent elasticity and friction, and has excellent physical/chemical properties to maintain a stable grip and high friction with the hand, and has an excellent service life.
