Abstract

The present invention relates to a connector capable of an increase in weight. According to the present invention, the connector capable of an increase in weight can reduce attachment and detachment time as a weight is mounted in the connector and the weight is able to detached. Moreover, the connector makes center of gravity stable by increasing weight by inserting the connector with the weight into a cue and moving the center of gravity toward the center of the cue. In addition, the connector blocks the shake of the cue by increasing a binding force between the cue and an extension as an elastic bumper is tightly coupled between the cue and the extension, thereby allowing more precise operation.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting material capable of weight deposition,

The present invention relates to a connecting member capable of weight deposition.

Generally, when playing a billiard game, you may not be able to set a normal bridge due to the distance between yourself and the water polo.

In the case described above, an auxiliary bridge (also known as a 'rest' or 'flippers') is traditionally used.

Recently, a method of excluding an auxiliary bridge and combining an extension for extending the length of the billiard cue to the end of the handle of the billiard cue has been used.

In this connection, JP-A-10-2012-0020729 discloses a billiard-stand extension.

The above-mentioned patent discloses a golf club comprising a coupling portion having an insertion hole into which a billiard cue is inserted, and an extension portion extending from the coupling portion along the insertion direction of the billiQ cage, wherein a friction member is provided on the inner wall of the insertion hole, A billiard cue substitution extension is disclosed.

However, in the billiard-cue substitute extension having the above-described structure, when the vent hole formed in the coupling part is blocked by the inflow of foreign matter, there is a problem in that separation between the extension and the billiard cue is difficult due to the pressure increase.

In addition, since the elastic force of the elastic member and the frictional force of the friction member act eccentrically, the conventional billi cue substitute extension has a problem in that a cue is generated as well as a cue in a desired direction can not be transmitted.

In addition, since the conventional billiard-cue substitute extension has a structure in which a friction member and an elastic member are provided in the insertion hole, there is a problem that the billiard cue is damaged by the elastic member and the friction member.

Further, there is a problem that additional weight deposition is difficult in addition to the weight of the extension that is coupled to the billiard cue.

In order to solve the above problem, a billiard cue substitution extension 20-2015-0007822 has been proposed.

The utility model includes a hollow cylindrical coupler; A collet inserted into one side of the coupler, the collet being hollow; A grip portion inserted into the other side of the coupler and having a hollow cylindrical shape and filled with sand or other packing material for holding the weight in the pipe portion of the grip portion.

However, when a filling material such as sand is fitted in the extension (grip portion), the center is easily biased downward by the gravity and it is easy to move in the inside of the extension fluidly. Therefore, when the cue operation is performed, This is a difficult problem.

In addition, since the weight can be deposited only in the inside of the extension, there is a problem that the overall center of gravity of the billiard cube does not fit.

Also, the process of attaching and detaching the filler material such as sand from the inside of the extension is complicated, which is troublesome and takes a long time.
