Hereinafter, the present invention will be described in detail with reference to the drawings.

The fitting 20 according to the present invention includes a bolt 100 and a bumper 200, as shown in FIGS. The fitting 20 of the present invention may further include a weight increasing member 300. The coupling 20 of the present invention is built in the billiard cage 10 to couple the billiard cue 10 with the extension 30 as described below. The fitting 20 of the present invention also acts as a weight.

In the coupling 20 of the present invention, the bolt 100 is composed of a head 110 and a body 120.

The body portion 120 of the bolt 100 has a hollow cylindrical shape. That is, the body portion 120 has a hollow cylindrical shape 121 inside thereof.

On the outer surface of the body part 120, a billet cage coupling screw 123 is formed. The billet cage coupling screw 123 may be formed over the entire outer surface of the body part 120 and may be formed in a part of a predetermined length from the end opposite to the head part 110, . When the body part 120 has the latter shape, it can be divided into a first body part 120-1 and a second body part 120-2. At this time, no screw is formed on the outer surface of the first body part 120-1, and a screw is formed on the outer surface of the second body part 120-2. The outer diameter of the first body part 120-1 is preferably slightly larger than the outer diameter of the second body part 120-2.

An extension engagement screw 125 is formed on the inner surface of the body part 120. [ The screw 125 for connecting the extension may be formed over the entire area of the inner surface of the body portion 120 and may include a portion of a predetermined length from the end that engages the head portion 110, Or may be formed in the first body part 120-1.

On the other hand, the weight increasing member engaging screw 127 may be formed on the inner surface of the body portion 120. The weight increasing member engaging screw 127 is screwed on the inner surface of the body part 120 at the distal end of the body part 120 of the bolt 100 facing the head part 110 of the bolt 100, And is formed on the inner surface of the second body portion 120-2. When the extension coupling screw 125 is formed on the inner surface of the body portion 120 over the entire inner surface area of the body portion 120 such an extension coupling screw 125 is inserted into the head portion of the bolt 100 At the end portion of the body portion 120 of the bolt 100 facing the first body portion 120-1 and the second body portion 120-2, for example, the weight increase member engagement screw 127 substantially becomes the inner surface of the second body portion 120-2. On the inner surface of the body part 120, a screw 125 for coupling an extension may be formed on a part of the inner surface of the body part 120, for example, the first body part 120- 1, the bolt 100 may be provided at the distal end portion of the body portion 120 of the bolt 100 facing the head portion 110 of the bolt 100, for example, at the inner surface of the second body portion 120-2, A weight increasing member engaging screw 127 is formed separately from the engaging screw 125.

Although the head 110 of the bolt 100 may have a different shape, it is preferable that the head 110 has a circular or cylindrical shape having a larger diameter than the body 120. The through hole 111 of the bolt 100 is formed to have the same or larger than the inner diameter of the body 120 and coincide with the inner hollow 121 of the body 120. Preferably, the through-hole 111 is formed of a polygonal wrench hole, particularly a hexagonal wrench hole, which is larger than the inner diameter of the body portion 120 but smaller than the outer diameter of the body portion 120. When the through hole 111 is formed by the hexagonal wrench hole 111, a part of the upper surface 128 of the body part 120 is exposed through the hexagonal wrench hole 111. As described below, It is possible to use a wrench since the wrench is supported by the upper surface 128 of the body portion 120 when the bolt 100 is coupled to the billet cage 10. [

In the present invention, the head 110 of the bolt 100 is fitted to the bumper 200. That is, since the bolt 100 is surrounded by the bumper 200, when the coupling hole 20 of the present invention is embedded in the billiard cage 10, the bolt 100 is not exposed to the outside. The bumper 200 is made of a rubber material and protects the billiard cage 10 from being damaged when the billiard cage 10 is placed on the floor of the billiard room. The bumper 200 is formed with a circular or polygonal hole 212 that is coincident with or larger than the through hole 111 formed in the head 110. It is convenient that the shape of the hole 212 is generally circular, but it is not excluded that the hole 212 has a polygonal shape in some cases.

The head 110 of the bolt 100 is provided with a lower surface 115 of the bolt 100 so that the head 110 of the bolt 100 is embedded more stably in the billet cage 10 after the head 110 of the bolt 100 is inserted into the bumper 200. [ A step 119 is formed at the periphery of the stepped portion. Correspondingly, the bumper 200 comprises a top surface 210 having a central or rounded or polygonal hole 212, a side 220 extending from the top surface 210, and a side 220 extending inwardly, (230), which is open except for the above. In the interior of the bumper 200, the fitting groove 240 is formed by the upper surface 210, the side surface 220 and the rim bottom surface 230. The head portion 110 of the bolt 100 is fitted into such an inside of the bumper 200, that is, the fitting groove 240. The head portion 110 of the bolt 100 is more stably engaged with the bumper 200 by engaging the bottom surface 119 of the head portion 110 with the bottom surface 230 of the bumper 200. [ The lower surface 115 of the head 110 except for the step 119 is leveled at the same height as the rim 230 of the bumper 200. When the coupling part 20 of the present invention is embedded in the billiard cage 10 after the head part 110 of the bolt 100 is inserted into the bumper 200, And the bottom surface 230 of the bumper 200 are brought into contact with the lower end surface 15 of the billiard cue unit 10 so that the coupling hole 20 of the present invention is stably installed inside the billiard cue base.

In the fitting 20 of the present invention, the weight increasing member 300 includes a body portion 310 and a threaded portion 320. The body portion 310 may be formed in a different shape, but is preferably formed in a cylindrical shape. The screw part 320 is formed to extend from the body part 310 in a cylindrical shape. The diameter of the threaded portion 320 is preferably smaller than the diameter of the body 310. Screws are formed on the outer surface of the threaded portion 320. The screw portion 320 of the weight increasing member 300 engages with the weight increase member engaging screw 127 formed on the inner surface of the second body portion 120-2 of the bolt 100. [ The diameter of the body portion 320 of the weight increasing member 300 is preferably smaller than the outer diameter of the second body portion 120-2 of the bolt 100. [ It is preferable that a polygonal wrench groove, particularly a hexagonal wrench groove 312, is formed on the lower surface of the body portion 320 of the weight increasing member 300.

As shown in Fig. 5, the coupling member 20 of the present invention having the above-described configuration is mounted inside the body portion 11 of the billiard cage 10. [ The bolt 100, the bumper 200, and the weight increasing member 300 are assembled before the coupling unit 20 of the present invention is mounted inside the billiard cue unit 10. [ The weight increasing member 300 is engaged with the bolt 100 by screwing the screw portion 320 to the weight increase member engaging screw 127 formed inside the second body portion 120-2 of the bolt 100. [ The weight increasing member 300 is screwed to the bolt 100 and then the wrench 300 is inserted into the wrench groove 312 of the weight increasing member 300 to tighten the weight increasing member 300 with the bolts 100 ). ≪ / RTI > The head 110 of the bolt 100 is inserted into the fitting groove 240 formed in the bumper 200 to complete the coupling between the bolt 100 and the bumper 200 as described above.

In the coupling 20 of the present invention, since the bolt 100 itself acts as a weight, the weight increasing member 300 may be omitted when a light weight is required. The fitting 20 of the present invention includes a bolt 100 made of a relatively light metal material such as aluminum and a bolt 100 made of a relatively heavy metal material such as stainless steel as a weight, It is desirable for the user to select the weight of the bolt 100 in accordance with his / her preference. In addition, the fitting 20 of the present invention includes both the relatively heavy weight-increasing member 300 and the relatively light weight-increasing member 300 so that the billiard game player (user) 300) to be selected.

5, the conventional coupling 20 of the present invention includes a conventional billiard cage 10 having a small diameter weight fitting groove 12 and a large diameter enlarging groove 14 therein And can be mounted inside. The weight increasing member 300 and the second body 120-2 are inserted into the small diameter weight fitting groove 12 provided inside the billiard cage 10. [ Since the diameter of the body portion 320 of the weight-increasing member 300 is smaller than the outer diameter of the second body portion 120-2 of the bolt 100, the weight-increasing member 300 can be easily inserted into the small- 12, the billet cage coupling screw 123 is provided on the outer surface of the second body portion 120-2, so that even if no screw is formed on the inner surface of the small-diameter weight fitting groove 12 The second body portion 120-2 can not be inserted into the small-diameter-weight fitting groove 12 only by pushing in the second body portion 120-2. That is, the second body portion 120-2 provided on the outer surface of the billet cage coupling screw 123 can be inserted into the small-diameter-weight fitting groove 12 by pushing the second body portion 120-2 while rotating. At this time, the inner diameter of the small diameter weight fitting groove 12 and the outer diameter of the billet cage coupling screw 123 coincide with each other.

The operation of inserting the second body portion 120-2 into the small diameter weight fitting groove 12 while holding the bumper 200 by hand is performed by the lower surface 115 of the head 110 of the bolt 100, And continues until the rim bottom 230 of the bumper 200 comes into contact with the lower end surface 15 of the billiard cue 10. At this time, the length of the first body portion 120-1 of the bolt 100 is substantially coincident with the length of the large-diameter enlarged groove portion 14. In this state, it is possible to complete the joining between the joining hole 20 and the billiard cue 10 in the present invention. However, in order to further secure the joining, the joining hole 20 of the present invention is further tightened . At this time, the wrench is inserted into the wrench hole 111 provided in the head 110 of the bolt 100 through the hole 212 provided in the bumper 200. Then, the wrench is hooked on the upper surface 128 of the first body part 120-1 of the bolt 100 and is not moved forward any more. Accordingly, the wrench can be supported by the upper surface 128 of the first body part 120-1 while being inserted into the wrench hole 111. [ Then, the wrench can be rotated, and the coupling hole 20 of the present invention is further tightened by the rotation of the wrench.

Although it is possible to provide the coupling port 20 of the present invention in the billiard cage 10 without the wrench hole 111, the coupling port 20 of the present invention is not firmly coupled to the billet cage 10 The coupling may become looser during use, resulting in inconvenience in use. Even if the wrench hole 111 is not provided, the coupling hole 20 of the present invention can be securely coupled to the billiard cage 10. However, since a strong coupling force is required for such a reliable coupling, There is a limit to securely mounting the sphere 20. Further, when the joining tool 20 of the present invention is strongly and firmly coupled to the billet cage 10, it is very difficult to release such a coupling with the bare hand. Therefore, it is preferable that the coupling hole 20 of the present invention has a wrench hole 111 in the head 110 of the bolt 100.

The outer diameter of the rim bottom surface 230 of the bumper 200 is smaller than the outer diameter of the lower end surface 15 of the billiard cue 10 in the state where the joining hole 20 of the present invention is installed on the billiard cage 10. [ That is, the edge portion of the lower end surface 15 of the billiard cage 10 is exposed even in the state where the coupling hole 20 in the present invention is installed in the billiard cage 10. [ The edge portion of the lower end face 15 of the exposed billiard cue 10 comes into contact with the edge extension portion 36 of the extension 30 as described below so that the billiard cue stand 10 and the extension 30 ) To be more stable.

As described above, the billiard cage (10) incorporating the coupling hole (20) of the present invention is in a state in which it can be used for the billiard game itself by having the coupling hole (20) as a weight. In addition, such a billiard cage 10 is itself ready to be coupled with the extension. Therefore, the joining opening 20 of the present invention plays a role of expanding the function of the conventional billiard cue 10. [

FIG. 6 is a perspective view of an extension according to an embodiment of the present invention, and FIG. 7 is a perspective view illustrating a state where a billiard cage equipped with a coupling hole according to an embodiment of the present invention is combined with an extension .

6, the extension 30 includes a cylindrical body portion 32 and a threaded portion 34 extending in a cylindrical shape from the body portion 32 and having a screw on the outer surface thereof. The diameter of the threaded portion 34 is sufficiently smaller than the diameter of the body portion 32. The length of the body portion 32 of the extension 30 can be appropriately selected depending on the degree to which the extension effect can be sufficiently obtained. The length of the threaded portion 24 is stably coupled to the hollow 121 and the threading screw 125 provided in the first body portion 120-1 of the bolt 100 in the coupling hole 20 of the present invention And can be appropriately selected depending on the degree of acceptability. The frame extension part 36 may be formed at the distal end of the body part 32 of the extension 30 to which the screw part 34 is coupled. This frame extension 36 allows the extension 30 to perform its engagement more reliably when coupled to the billiard cage 10 by the coupling 20 of the present invention.

7, the threaded portion 32 of the extension 30 passes through the hole 212 provided in the bumper 200 and the through hole 111 provided in the head 110 of the bolt 100, The coupling 20 of the present invention engages with the extension 30 by engaging with an extension coupling screw 125 formed in the first body part 120-1 of the body 100 of the present invention. At this time, the extension portion 36 of the extension 30 surrounds the bumper 200 and comes into contact with the lower end surface 15 of the billiard cue 10. In addition, in addition, the end surface of the extension 30 can contact the upper surface 210 of the bumper 200. So that the extension 30 is firmly coupled to the billiard cue 10.
