Description

Choke case for increased lift adjustment and size compatibility {Chalk case for increased lift adjustment and size compatibility}

The present invention relates to a choke case with increased lifting/lowering control and standard compatibility, and more particularly, an inner body that pressurizes and accommodates a choke, and an external that selectively applies a pressing force to the inner body as it ascends and descends through screw coupling with the inner body As it is composed of a body, it is possible to select the desired height for the height of the choke accommodated in the inner body and at the same time pressurize the outer surface of various chokes. is about

Billiards (撞球) is a sport in which the player who reaches a predetermined scoring goal first by releasing multiple billiard balls on a horizontally installed square billiard table and hitting the billiard balls in sequence using a long stick-shaped cue wins. It's a game.

It is known that billiards started out as an outdoor sport similar to cricket in Europe around the 14th and 15th centuries, and then developed into an indoor game as it is today with the development of a tip and chalk made of compressed leather attached to the end of the cue.

The choke is rubbed on the tip attached to the end of the cue to prevent the cue from slipping when hitting the billiard ball with the cue and to accurately hit the point desired by the player. Usually, ceramic powder is compressed into a cube shape together with pigments and adhesives. It is manufactured by molding. These tip chokes are sometimes priced at tens of thousands of won for professionals, so they are stored in a choke-only case to prevent damage to the choke itself, prevent choke powder from getting on the player's hand, and increase the grip when in use. use it as

However, as the number of times the tip is rubbed increases, the size of the tip choke wears out and becomes smaller. Therefore, choke cases have been proposed in which the choke, which has been reduced in size by use, is pushed up on the case so that the choke can be used more conveniently to the bottom.

For example, in Utility Model Registration No. 20-0463152 (October 12, 2012), as shown in FIG. 1 , a rectangular parallelepiped-shaped case 2 in which a choke is inserted into an open upper portion, and the case 2 ) A choke case for billiards made of a disk-shaped lifting plate 3 installed inside is introduced. The case (2) has a circular through hole (not shown) formed on the bottom surface, has a radius greater than the shortest distance from the inner center point to the adjacent side and smaller than the shortest distance to the adjacent edge, and the thread is formed on the inner peripheral surface. (2a) has a structure in which depressions are formed on four surfaces.

In addition, the disc-shaped lifting plate 3 has a screw thread 2b coupled to the screw portion 2a on the outer diameter surface, and an insertion protrusion 3a inserted corresponding to the through hole in the center of the bottom surface. is formed, and has a structure in which a straight groove 3b is formed on the bottom surface of the insertion protrusion 3a so as to be rotated with a screwdriver or other tool.

Therefore, when the elevating plate 3 is rotated by inserting a screwdriver into the groove 3b, the elevating plate 3 rises while the screw thread 3c rotates along the screw portion 2a, and at the same time the case 2 ), the choke inserted inside will rise. However, the choke case of this structure has the inconvenience of using a tool such as a screwdriver to push up the choke.

In addition, in Patent Registration No. 10-1722355 (March 27, 2017), a choke case for billiards is introduced in which the height of the choke can be easily adjusted and fixed. The choke case, as shown in FIG. 2, provides a space for accommodating a portion of the body of the tip choke 10, and includes a lower housing 110 having a screw hole 119 formed on one side thereof, and the tip An upper housing 120 coupled to the lower housing to cover the rest of the body of the choke 10 , and a stopper 130 screwed to the screw hole 119 to fix the choke 10 so that it does not flow ) is included.

In the case of the choke case, in order to push up the reduced choke 10, first push up the choke 10 in a state in which the stopper 130 is released, and then tighten the stopper 130 again. have. And, when the stopper 130 is tightened, the choke 10 itself is inevitably damaged because the end of the stopper 130 digs into the choke 10, and thus the choke 10 is worn out and has a smaller size. ) has a problem that it cannot be used.

Therefore, there is a need for a choke case that can be used by easily lifting and lowering the choke in response to the height drop due to long-time use of the choke.

In addition, although most of the chokes have a hexahedral shape, various types of chokes are being distributed.

For example, various shapes are being used, such as cylindrical (horizontal cross-section is a circle), octahedron (horizontal cross-section is hexagonal), or decahedron (horizontal cross-section is octagonal).

In addition, not only the various shapes but also the horizontal and vertical sizes in the horizontal section are also slightly different for each choke being sold.

Therefore, in the case of the choke case according to FIG. 1 described above, a choke larger than the inner size of the case 2 cannot be accommodated and thus cannot be used.

Of course, in the case of the choke case according to FIG. 2, it can be prevented from being separated by tightening through the stopper 130, but as described above, the stopper has a problem in that the choke is damaged.

Therefore, it is required to improve the choke case so that it can be fixed in the choke case regardless of the height adjustment according to the long-time use of the choke and the specifications of various chokes.
