Multi-stage choke case {CHALK CASE}

The present invention is to safely protect the choke used for billiards, to keep it convenient, and to conveniently use it completely up to the rim of the choke, the main body having a receiving part into which the choke is fitted; and a cover detachable to open and close the upper opening of the accommodating part; wherein the main body includes a base having a choke fixing part made of a bottom part and side wall parts, and is stacked and detachable on the top of the base and is detachable and made of side wall parts It relates to a multi-stage choke case that includes one or more powders having a choke fitting part, and can separate and use the powder according to the amount of choke used.

Billiards, one of hitting sports, has a tip of a predetermined material attached to the tip of a cue for billiards, so that when hitting a billiard ball, it is struck or touched with appropriate friction and cushion to transmit a desired direction, force, and rotational force to the billiard ball.

At this time, when the tip of the cue is struck or touched by the billiard ball, the tip is coated with chalk to prevent a miss, while maintaining proper friction and cushioning.

These chalks are made of a natural or synthetic material such as chalk in the form of a rectangular block in cross section.

If the block-type raw material for chalk is directly painted and used, the chalk can easily get on the back of the hand. Conventional chalk is packed with packaging materials such as paper or plastic on the side and bottom of the chalk, and chalk is applied only through the top opening. made it possible

The choke packaged in this way is a case to prevent the choke from getting on your hands, but since the side slopes and the bottom are blocked with the case, if you continue to paint the choke, only the central part of the choke will wear out, and the outer rim of the choke cannot be used completely. Since it is difficult to paint the chalk even when the remaining amount is left enough for use, the chalk must be discarded and replaced with a new one, so there is a problem of severe waste compared to the material used.

In this regard, there is disclosed Patent No. 10-2097892,

Including one or more powders (10B) stacked on top of the base (10A) and detachable, and having a choke block fitting portion (10a) made of side wall portions,

It is characterized in that the powder 10B can be separated and used according to the amount of the choke block (C) used.

The multi-stage choke case of the present invention has a hexahedral shape and can be protected by covering the front, rear, left, right, and upper and lower surfaces of the choke,

The main body 10S is fitted with a choke block (C) having a height at which an upper portion of the choke block (C) protrudes to be exposed. It is configured to protect the choke block (C) that is exposed as a choke and, when in use, remove the cover (20) to hold the main body (10S) and paint the choke on the cue for use.

The main body 10S may introduce a light-transmitting color by using a known plasma coating method.

In particular, as the main body 10S of the present invention is composed of the base 10A and one or more powders 10B, when the choke block C is used close to the uppermost height of the body 10S, the powder 10B By separating the choke block (C) inside the main body (10S) to be exposed again, there is an advantage that, unlike the existing multi-stage choke case, even the outer edge of the choke block (C) can be completely used.

In the drawings of the present specification, the two-stage body 10S of the form in which one powder 10B is assembled on one base 10A is representatively shown, but by lowering the height of the powder 10B, two to three It goes without saying that the powder 10B may be configured as a multi-stage body 10S of 3 to 4 stages to which the powder 10B is assembled.

First, the base 10A includes a hexahedral bottom part with an open top and first sidewall parts, and the inside of the base 10A is pushed inside the first sidewall part to grab the outer surface of the choke block C. The main gripper is provided, so that the choke block C is not easily removed from the main body 10S.

In particular, the gripper includes a connection part fixed across the upper surface of the bottom part, and a pressing part 31 bent upwardly and elastically supported inward at both ends of the connection part, and a pair of grippers 30A and 30B It is assembled to be cross-arranged in a '+' shape at the bottom of the base 10A.
