Aiming Device For Billiard Cue

Abstract

An aiming device for a billiard cue is disclosed herein, which includes a fixing member, an extending member coupled with the fixing member at one end thereof, a parallel light source coupled with the other end of the extending member and having a projection hole for passing a parallel light beam emitted from the parallel light source, and a cylindrical lens mounted on one end of the parallel light source in front of the projection hole, whereby the parallel light beam becomes a fanned light beam after it passes through the cylindrical lens. The aiming device of the present invention can provide a high precise aiming in billiards.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an aiming device for a billiard cue, and in particular to an aiming device that can provide a high precise aiming in billiards.[0003]2. The Prior Arts[0004]Generally, when striking a cue ball, people use naked eyes to aim at the ball. Due to the inaccuracy of the viewing angle and the difficulty of long-distance aiming, the way of aiming at the ball by naked eyes is not precise enough. It can only help a little to adjust the striking strength and direction of the cue. Hence, ordinary people except for those skilled billiard players are hard to aim at the ball precisely by naked eyes.[0005]Currently, aiming reference points are located at a periphery of a conventional billiard table. If these points are located at the other side of the table, it is inevitable to have a deviation of aiming by naked eyes. Later a laser light aiming device was produced, which could project a light point onto...

AI Technical Summary

Benefits of technology

[0008]According to the present invention, the parallel light source may be a laser light source or other light sources. The fixing member may be a fixing clamp or a clamp that is sleeved on the billiard cue and fastened with screws. There is no limitation to the structure of the fixing member as long as it can fix the aiming device with the billiard cue. The extending member may be, but not limited to, a curved rigid member. Any flexible or bendable extending members such as a flexible member in accordance with the present invention or a multiple rod linkage with ball pivot mechanisms are applicable, so as to be capable of adjusting a desired angle and a range of the projection light emitted from the parallel light source. The cylindrical lens may be a circular, biconvex, biconcave, plano-convex, or plano-concave cylindrical lens.

[0009]The parallel light beam can be refracted by the cylindrical lens to produce a fanned light beam. The fanned light beam is projected to form a projection line when it radiates on a surface of an object. Along the projection line, the billiard cue is in alignment with the cue ball and the object ball so that the cue ball can be hit to impact onto the object ball precisely. Travel trajectories of the cue ball and the object ball can be controlled through the help of the projection line.

Problems solved by technology

Due to the inaccuracy of the viewing angle and the difficulty of long-distance aiming, the way of aiming at the ball by naked eyes is not precise enough.

It can only help a little to adjust the striking strength and direction of the cue.

Hence, ordinary people except for those skilled billiard players are hard to aim at the ball precisely by naked eyes.

Later a laser light aiming device was produced, which could project a light point onto an object ball to be struck, but there is not a baseline between the projection point and the billiard cue, thereby players still cannot aim at the ball precisely.
