BACKGROUND OF THE INVENTION

The present invention relates generally to billiard games, and more particularly, to a uniquely configured pool instructional device and methodology specifically adapted for illuminating a strike point of an object ball and illuminating a projected path of the object ball to a target pocket.
Pocket billiards is a recreational game enjoyed by many people of various ages, interests, and skill levels. As is well known, the object of pocket billiards is to sink a certain number of object balls into various pockets of a pool table using of a cue ball and a cue stick. In the course of sinking an object ball, a pool player must understand how to properly aim the cue ball so that it strikes the object ball and causes the object ball to follow a path towards the target pocket. As many may testify, the skill of aiming is often a difficult one to hone.
In developing the skill of aiming the cue ball, a player should visualize the geometric linear relationship between the cue ball, the object ball and the target hole. Most players understand that when struck by the cue ball, the path along which the object ball travels is dependent upon the position on which the object ball is struck. For example, a player may know that striking an object ball from the left causes the object ball to move to the right, and vice versa. Nevertheless, despite the simplicity of the geometric linear relationship, the player may realize that the object ball must be struck precisely in order to achieve a desired result. More specifically, the object ball will travel along a straight line originating at where the cue ball contacts the object ball and extending through a center of the object ball.
Applying this principle generally, where the object ball need not rebound from an edge of the pool table to enter the target pocket, the player may visualize the straight line passing from the target pocket and through the center of the object ball to a strike point on the surface of the object ball. It is this strike point that a player must hit when contacting the object ball with the cue ball in order to cause the object ball to enter the target pocket. Thus, according to this methodology, in order to strike the object ball for a precise result, the player must visualize not only the straight line originating from the target pocket through the center of the object ball, but the player must also visualize the strike point of the object ball.
Included in the prior art are several devices and methods directed towards aiding a pool player in refining the skill of aiming a cue ball. For example, some prior art devices attach a laser sighting device to a cue stick in order to aid the player in visualizing the path of a cue ball. Similar inventions place the laser guide inside of the cue stick. Yet other inventions utilize optical mirrors spaced along the edges of a pool table in conjunction with the aforementioned laser sighting device. However, applicant is unaware of any device which displays the aforementioned straight line that the object ball must travel in addition to displaying the strike point of the object ball.
As can be seen, there exists a need in the art for a pool instructional device that accurately indicates the location of the strike point on an object ball as well as the projected path of the object ball toward the target pocket once hit at the strike point. Furthermore, there exists a need in the art for a pool instructional device configured to provide a visual display of an approach path of the object ball as it approaches the edge of the pool table and the reflection path of the object ball.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings wherein the showings are for purposes of illustrating preferred embodiments of the present invention only and not for purposes of limiting the same, FIG. 1 is a perspective view of a pocket billiards instructional device 10 including a stand 12, a target optical head 14, and an object optical head 20. The target optical head 14 may define a principal axis 16 and may be selectively rotatable thereabout. The target optical head 14 may also be operative to emit a target optical beam 18 and may be attachable to the stand 12. The object optical head 20 may be operative to emit an object optical beam 22 and may be selectively rotatable about the principal axis 16 relative to the target optical head 14.
As shown in FIG. 1, the object optical head 20 may be attachable to the stand 12. It is contemplated that the principal axis 16 may be coincident with the stand 12 as shown in FIG. 1. However it is also contemplated that the principal axis 16 may be located distally from the stand 12 in other embodiments. In this regard, it is contemplated that the object optical head 20 may be independently rotatable about the principal axis 16. Nevertheless, according to one aspect of the present invention, the object optical head 20 may rotate about the principal axis 16 relative only to the target optical head 14. Thus, according to an embodiment of the present invention, the principal axis 16 may be coincident with the stand 12. In this regard, the object optical head 20 and the target optical head 14 may be attached to the stand 12 such that the target optical head 14 and the object optical head 20 rotate about the stand 12 and the principal axis 16 with the object optical head 20 rotating relative to the target optical head 14.

It is contemplated that the laser line 34 may be a preferred configuration of the object optical beam 22 when the object optical beam 22 is utilized to illuminate an approach path 44 on the pocket billiards table 32. Additionally, when the object optical beam 22 illuminates a strike point 42 on the object ball 40, it is contemplated that a laser point 46 may be a preferred configuration of the object optical beam 22. Nevertheless, it is also contemplated that when illuminating the strike point 42 on the object ball 40, the object optical beam 22 may similarly be configured in the shape of a cross or other geometric configuration to indicate the strike point 42 on the object ball 40.
Referring again to FIG. 1, in accordance with another aspect of the present invention, the target optical head 14 may define a transverse target axis 48. The transverse target axis 48 may be oriented orthogonally relative to the target plane 24. The target optical head 14 may be selectively rotatable about the transverse target axis 48. Additionally, the object optical head 20 may define a transverse object axis 50. The transverse object axis 50 may be oriented orthogonally relative to the object plane 36.

However, the transverse target axis 48 may be located distally from the principal axis 16. In the same regard, it is contemplated that the transverse object axis 50 may intersect with the principal axis 16. However, it is also contemplated that the transverse object axis 50 may be located distally from the principal axis 16. In this regard, it is also contemplated that the target optical head 14 and the object optical head 20 may be configured with the principal axis 16 intersecting with the transverse target axis 48 and the transverse object axis 50.

However, it is also contemplated that the stand 12 may be of any configuration such that the pocket billiards instructional device 10 may be suitably supported and balanced on a pocket billiards table 32 or an edge 54 of a pocket billiards table 32. However, it is contemplated that the stand 12 may be attached to a structure located remotely from the pool table. For example, it is contemplated that the stand 12 may be attached to a ceiling above the pool table, and the stand 12 may be configured to provide movement of the object optical head 20 and the target optical head 14 with a respect to the pool table such that the pocket billiards instructional device 10 may be utilized as disclosed herein. Additionally, it is contemplated that the stand 12 may also permit the pocket billiards instructional device 10 to be positioned adjacent the pool table on the ground and likewise permit the pocket billiards device to be utilized as disclosed herein. The stand 12 may also be removably attachable to the edge of the pocket billiards table 32. It is contemplated that the stand 12 may connect with a track placed about the periphery of the pocket billiards table 32 to facilitate the removal and attachment of the stand 12 to the edge of the pocket billiards table 32. It is also contemplated that other configurations may be utilized to further facilitate the removal and attachment of the stand 12 to the edge of the pocket billiards table 32.
Referring now to FIGS. 1 and 3, according to a further aspect of the present invention, the target optical head 14 may include a target angle measuring tool 56.

The reference line 60 is an imaginary line that emanates from the edge at the point where the object ball 40 strikes the edge in order to rebound toward the target pocket 28. It is contemplated that the exact location of the reference line 60 may be found through adjusting the position of the pocket billiards instructional device 10 along the edge of the pocket billiards table 32. Additionally, the object optical head 20 may include an object angle measuring tool 62. The object angle measuring tool 62 may be operative to indicate an angle of reflection 64 of the object path relative to the reference line 60. It is contemplated that the target angle measuring tool 56 and the object angle measuring tool 62, as shown in FIG. 1, may be a physical measurement of the rotation of the respective ones of the target optical head 14 and the object optical head 20 about the principal axis 16.

Such an embodiment may be utilized if the object optical head 20 is rotatable about the principal axis 16 relative to the target optical head 14 and the target optical head 14 is rotatable about the principal axis 16. In this regard, the target angle measuring tool 56 and the object angle measuring tool 62 may also be integrally formed.
It is further contemplated that the angle of reflection 64 should equal the angle of incidence 58 in order to approximate the geometric behavior of the object ball 40 as it approaches the edge of the pool table and bounces off the edge of the pool table. As mentioned above, the exact point of the reference line 60 may be found by adjusting the position of the pool instructional device along the edge of the pocket billiards table 32. When the angle of incidence 58 is equal to the angle of reflection 64, as shown through geometry, the object ball 40 may reflect off of the edge and rebound toward the target pocket 28. It is contemplated that the target angle measuring tool 56 and the object angle measuring tool 62 may be configured to properly indicate the angle of incidence 58 of the target path 30 relative to the reference line 60.
