Abstract
The laser billiard ball positioning apparatus is an invention that provides continuous real time visual positioning feedback to assist in properly positioning a billiard ball. The laser billiard ball positioning apparatus provides positioning information without causing any interference with the rolling trajectory of a billiard ball. The laser billiard ball positioning apparatus further provides for a positioning target that is never covered up by a billiard ball. The laser billiard ball positioning apparatus is primarily intended for use by billiard players in properly positioning billiard balls prior to the initiation of a game of billiards.
Description
- The present invention relates to laser billiard ball positioning and alignment devices. The invention in particular is useful in positioning a billiard ball without the assistance of a patch or target being physically located on the billiard table playing surface.
- It is common practice when playing the game of billiards or pool or the like to first position the non-cue balls. Such positioning is typically performed by placing the non-cue balls in a triangular shaped rack which is moveably located on a billiard table or the like playing surface. The lead ball, often the number “1” ball, is then moved such that the lead ball is positioned immediately over a patch type target. Once positioned, a game of billiards or the like is ready to be initiated. It is common for the lead ball target to consist of a colored circular patch affixed to the target location of the billiard table or like playing surface. A problem with such a target patch is that during play of a billiard or like game, due to the thickness of the target patch which causes the target patch to extend above the playing surface, if a billiard or like ball rolls over such target patch, the target patch can and often does alter the trajectory the billiard or like ball would otherwise travel. Yet a further problem with the conventional target patch is that if the lead ball is positioned on or near the target patch, then the target patch is covered by one or more of the billiard or like balls and the rack.
- It is well known that laser indicators or “pointers” have existed for some time and have enjoyed substantial use in a variety of applications. Specifically, with regards to the game of billiards and pool, a laser light emitting device has been mounted to a billiard cue stick to assist the user of the cue stick in aligning the billiard cue stick. See for instance U.S. Pat. Nos. 6,155,929 and 5,554,075. Furthermore, the use of laser light in combination with a complex system of mirrors and computer processing to assist in the rating of shots and the display of optimal paths is taught in U.S. Pat. No. 4,882,676. Additionally, the use of a simple laser emitting device to provide real time continuous positioning feedback has been used to position things such as a vehicle in a garage. See for instance U.S. Pat. Nos. 6,218,962 and 6,154,150. U.S. Pat. Nos. 6,218,962, 6,155,929, 6,154,150, 5,554,075 and 4,882,676 are incorporated herein by reference and form a portion of this specification.
- However, none of the prior art has taught a simple real time continuous feedback laser assisted lead ball positioning device.
- The present invention relates to a billiard ball or like locating apparatus having a light emitting device that emits a light beam of a predetermined pattern on a predetermined location of a billiard table or like surface. The invention further includes at least one billiard or like ball that is positionable so as to be able to be positioned at the predetermined position of the billiard table or like surface. In practice, when the ball is so positioned, the predetermined light pattern is displayed on the surface of the ball, indicating that the ball is properly positioned. Such positioning is performed without the assistance of a physical target such as a patch being located on the playing surface.
- The preferred embodiment of the invention comprises a laser light emitting device, a billiard or like table having a playing surface, and at least one billiard or like ball. While a light other than a laser light may be used in the invention, a laser light is preferred due to the reduced scatter of the laser beam. The laser light emitting device includes a lens which causes the projected laser light pattern to form a pattern of a cross or “cross hairs”. Other patterns such as concentric circles with a center dot may also be used. The length of each of the two cross hairs are preferably substantially equal to the diameter of the billiard or like ball such that when the entire length of each cross hair is projected on the billiard or like ball, such projection indicates that the billiard or like ball is properly positioned.
- The laser light emitting device further includes a suction cup or like suitable member so as to enable mounting of the light emitting device in a position above the table playing surface such as by mounting the light emitting device to a ceiling by pressing the suction cup member to the ceiling. The laser light emitting device is preferably battery powered and includes an on/off switch. However, the light emitting device may alternatively be adapted to receive electrical power from a standard wall power outlet and the light emitting device may have a remote control device to selectively turn the light emitting device on and off.
- In practice, the light emitting device is mounted to the ceiling by pressing the suction cup member against the ceiling such that the light emitting device becomes mounted to a ceiling above a billiard table playing surface. The location on the ceiling to which the light emitting device is mounted is selected such that when the light pattern from the light emitting device is focused on the playing surface, the light pattern is at the location on the playing surface where the lead billiard ball is to be positioned. Billiard balls are then placed in a billiard ball positioning rack on the billiard table playing surface. With the positioning rack in place around the billiard balls, the billiard balls are then rolled on the playing surface into proper position. Thus when the cross hairs of the laser light emitting device are projected substantially completely on the lead billiard ball surface, it is readily understood by the user that the lead billiard ball is positioned correctly. Alternatively, when the cross hairs of the laser light emitting device are not projected substantially completely on the lead billiard ball surface, it is readily understood by the user that the lead billiard ball is not positioned correctly.
- Accordingly, in the preferred embodiment it is an object of the present invention to provide a simple positioning assistance device that provides real time continuous position feedback information. It is a further object of the present invention to provide a positioning device having a target pattern that is never covered by a billiard ball or like object that is to be positioned. It is still a further object of the present invention to provide a positioning device that does not interfere with the trajectory of a billiard or like ball.
- The objects and many attendant advantages of this invention will be readily appreciated and become readily apparent as the same becomes better understood by reference to the following detailed description, when considered in conjunction with the accompanying drawings and in which like reference numerals designate like parts throughout the figures thereof and wherein:
- FIG. 1 is an isometric view of the billiard ball positioning apparatus. The front portion of the billiard table and the table legs are not shown.
- FIG. 2 is a close up plan view of the view of the billiard ball positioning apparatus taken at the location indicated by
view indication arrows 2 as shown in FIG. 1. The laser light emitting device and the majority of the billiard table are not shown. The lead billiard ball is shown positioned correctly. - FIG. 3 is substantially identical to FIG. 2 except that FIG. 3 displays the lead billiard ball positioned incorrectly.
- In order to facilitate the understanding of the present invention in reviewing the drawings accompanying the specification, a feature list is provided below. It is noted that like features are like numbered throughout all of the figures.
