Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of request GB2502798.8 filed Feb. 26, 2025, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION1. Field of the Invention

[0002] The present invention relates generally to billiard and snooker training and practice devices. More particularly, the present invention relates to an automated billiard ball launching device that is capable of storing, feeding, and launching billiard balls onto a playing surface at controlled distances and angles, thereby enabling repetitive shot practice without requiring the player to manually reposition balls.BACKGROUND OF THE INVENTION

[0003] The game of billiards, including pool and snooker, requires considerable skill development through repetitive practice. Skilled players and instructors must practice specific shots repeatedly to develop muscle memory, refine cue ball control, and master various spin techniques. Effective practice requires the consistent placement of object balls in precisely the same location for each repetition.

[0004] Current billiard training aids primarily focus on alignment and stroke mechanics through passive devices such as mirrors, laser alignment systems, and stroke guides. While these tools help with certain aspects of technique, they fundamentally lack the capability to consistently recreate specific shot scenarios for repeated practice. Existing practice aids, such as alignment templates and specialized practice balls, require manual ball placement by the player, which introduces variability in ball positioning and significantly reduces practice efficiency.

[0005] Furthermore, on a standard 9-foot billiard table, a player who wishes to repeatedly practice a single shot must walk around the table to retrieve and reposition the object ball after each attempt. This manual process is not only physically tiring but also breaks the concentration and rhythm essential to developing consistent muscle memory. For billiard instructors working with students, this inefficiency is compounded, as the instructor must repeatedly place balls while simultaneously providing coaching.

[0006] Prior art solutions for ball delivery in billiard-related applications have taken various approaches. U.S. Pat. No. 884,699 discloses a billiard ball transport apparatus employing a vertical support with horizontal ramps to convey balls toward a table surface. While this patent addresses the general concept of ball transport, it relies on a purely gravity-driven passive system that does not provide controlled launching with adjustable distance or repeatable ball placement at a predetermined position on the playing surface.

[0007] U.S. Pat. No. 4,422,637 describes an apparatus for positioning billiard balls on a table using a tower structure with circular and straight rods for storing and guiding balls onto the playing surface. However, this device similarly relies on gravity feed without electronic control, offers no capability for adjusting launch parameters, and does not incorporate any form of remote operation.

[0008] U.S. Pat. No. 11,439,891, assigned to the Rock-It Launcher product, describes an apparatus that receives and positions billiard balls on a table using an inclined rail with a pivoting rod to release balls one at a time. While this represents a more recent attempt at solving the problem, it still operates as a gravity-based release mechanism without powered propulsion, and thus cannot provide the controlled, repeatable ball placement at a consistent distance that is necessary for effective repetitive practice.

[0009] In adjacent technical fields, powered ball delivery systems have been employed. U.S. Pat. No. 3,003,770 discloses a golf ball dispenser utilizing a wheel with vanes for ball distribution. U.S. Pat. No. 4,360,204 describes a golf ball dispensing apparatus featuring remote activation capability. However, these golf-related devices are designed for dispensing balls at a fixed point and are not adapted for the unique requirements of billiard ball launching, which demands precise distance control and gentle placement on a felt playing surface without damaging the table.

[0010] None of the existing solutions in the art provide a compact, battery-powered device that combines electronic impeller-based ball propulsion with an integrated multi-ball storage and feeding system, interchangeable angle-adjustable off-ramps, microprocessor-controlled launch parameters, and wireless remote operation. There remains a significant unmet need in the art for a billiard ball launching device that can automatically and repeatably deliver balls to a consistent position on a playing surface, enabling efficient repetitive practice sessions.BRIEF SUMMARY OF THE INVENTION

[0011] The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key / critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description that is presented later.

[0012] It is a main object of the present disclosure to provide a a billiard ball launching device that overcomes the limitations of the prior art and enables efficient, repetitive billiard practice.

[0013] It is a main advantage of the present invention that it provides a housing with a ball cradle extending integrally from a casing thereof and an electronically controlled impeller mechanism extending integrally from said housing, capable of consistently launching billiard balls onto a playing surface at predetermined angles and distances for practice purposes. Unlike prior art gravity-fed systems, the electronically controlled impeller of the present invention provides powered, adjustable propulsion that ensures repeatable ball placement.

[0014] It is a further advantage of the present invention that it provides a multi-component ramp system for ball feeding and guidance, comprising a lower ramp component, an upper ramp component, and a curved ramp connecting the upper and lower ramp components, enabling the storage of multiple billiard balls that are automatically and sequentially fed to the launching position. This automated feeding capability allows a player to practice multiple shots in succession without interruption.

[0015] It is yet another advantage of the present invention that it provides a remote control system for wireless operation, allowing a player to remain in a shooting position and trigger ball launches without having to walk to the device. This feature is particularly valuable for maintaining concentration and muscle memory during repetitive practice.

[0016] It is still another advantage of the present invention that the impeller system is driven by a servo-motor and controlled by an internal microprocessor, enabling precise calibration of launch distance and ensuring that each ball is delivered to substantially the same position on the playing surface.

[0017] It is a further advantage of the present invention that it includes a set of interchangeable ball off-ramps with varying exit angles, including straight, 15-degree, and 25-degree configurations, allowing the player to direct balls to different areas of the table without repositioning the device itself.

[0018] It is yet a further advantage of the present invention that the device is battery-powered using a removable rechargeable lithium battery, making the device fully portable and eliminating the need for external power connections that could interfere with play around the table. The battery is removable and rechargeable externally using a charging cable provided with the device, thereby simplifying the construction of the device and eliminating the need for integrated charging circuitry within the casing.

[0019] It is another advantage of the present invention that the compact, rectangular housing is designed to sit at the edge of or on the rail of a billiard table, occupying minimal space while providing full functionality including ball storage, feeding, launching, and angle adjustment capabilities.

[0020] According to a first broad aspect of the present invention, there is provided a billiard ball launching device comprising: a housing defining a rectangular casing; a ball cradle extending integrally from the casing and dimensioned to receive and hold a single billiard ball prior to launch; an electronically controlled impeller mechanism extending integrally from the housing and operatively positioned to engage a billiard ball held in the ball cradle, the impeller mechanism being operable to propel the billiard ball from the ball cradle and onto a playing surface at a controlled distance; a multi-component ramp system connected to the housing for storing a plurality of billiard balls and sequentially feeding the billiard balls to the ball cradle, the ramp system comprising a lower ramp component secured to the ball cradle, an upper ramp component attached to the housing, and a curved ramp connecting the upper ramp component to the lower ramp component; and a remote control unit in wireless communication with the housing for remotely activating the impeller mechanism.

[0021] In certain embodiments, the impeller mechanism comprises a servo-motor and an impeller wheel with vanes, the servo-motor being controlled by an internal microprocessor to regulate the rotational speed of the impeller wheel and thereby control the launch distance of the billiard ball.

[0022] In certain embodiments, the device further comprises at least one interchangeable ball off-ramp selectively attachable to an output end of the housing, each off-ramp defining a different exit angle selected from the group consisting of a straight configuration, a 15-degree angle, and a 25-degree angle.

[0023] In certain embodiments, the device further comprises a removable rechargeable lithium battery housed within the casing, and a battery holder for receiving the battery, the battery being removable from the casing for external charging.

[0024] In certain embodiments, the housing further comprises a ball-launching switch in the form of a lever disposed on a top surface of the casing for manual activation of the impeller mechanism, and an impeller calibrating switch disposed proximal to the ball-launching switch for adjusting the launch parameters of the impeller mechanism.

[0025] The foregoing has outlined rather broadly the more pertinent and important features of the present disclosure so that the detailed description of the invention that follows may be better understood and so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter which form the subject of the claims of the invention.

[0032] The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the general principles of the present invention have been defined herein.

[0033] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. The terms “a” or “an,” as used herein, are defined as to mean “at least one”. The term “plurality,” as used herein, is defined as two or more. The term “another,” as used herein, is defined as at least a second or more. The terms “including” and / or “having,” as used herein, are defined as comprising (i.e., open language). The term “coupled,” as used herein, is defined as connected, although not necessarily directly, not necessarily mechanically, and not permanent. The term “providing” is defined herein in its broadest sense, e.g., bringing / coming into physical existence, making available, and / or supplying to someone or something, in whole or in multiple parts at once or over a period of time. As used herein, the terms “about”, “generally”, or “approximately” apply to all numeric values, whether or not explicitly indicated. These terms generally refer to a range of numbers that one of skill in the art would consider near the stated amount by about 0%, 5%, or 10%, including increments therein. In many instances these terms may include numbers that are rounded to the nearest significant figure.

[0034] Referring now to the drawings, and more particularly to FIG. 1, there is shown a billiard ball launching device, generally designated by reference numeral 11, according to a preferred embodiment of the present invention. The device 11 is designed to be positioned at the edge of a billiard table and is operative to automatically store, feed, and launch billiard balls 14 onto the playing surface at controlled distances and angles.

[0035] The device 11 comprises a rectangular casing 11 which serves as the main housing unit. The casing 11 is preferably constructed from a durable, lightweight material such as high-impact plastic or aluminum, and is dimensioned to sit stably on or adjacent to a billiard table rail. The casing 11 is inscribed with the trade designation “O.B. Spotter” in the illustrated embodiment.

[0036] A ball cradle 12 extends integrally from the casing 11 and is dimensioned and configured to receive and hold a single billiard ball 14 in a launch-ready position. The ball cradle 12 is connectable to the casing 11 by a snap-fit engagement, as best seen in the exploded view of FIG. 1. The ball cradle 12 is shaped to conform to the curvature of a standard billiard ball (approximately 2.25 inches in diameter for pool, or 2.0625 inches for snooker) and securely holds the ball 14 in alignment with the impeller mechanism 24 prior to launch. As best seen in FIG. 4B, the ball cradle 12 positions the ball 14 at the correct height and orientation for consistent launching.

[0037] The device 11 is powered by a removable rechargeable lithium battery 18 which is received in a battery holder 19 within the casing 11. As shown in FIG. 2, the battery 18 and battery holder 19 are accessible for battery replacement or removal. The battery 18 is rechargeable externally using a charging cable provided with the device, and no charging circuitry is integrated into the casing 11. An on / off switch (not shown) is disposed on a side of the casing 11 for powering the device on and off.

[0038] An internal microprocessor (not shown) is housed within the casing 11 and controls all electronic operations of the device 11. The microprocessor manages the impeller speed, processes signals from the remote control unit 26, and coordinates the launch sequence. The microprocessor is programmed to store and recall calibration settings, enabling the device 11 to deliver balls to a consistent position on the playing surface.

[0039] Referring still to FIG. 1, a ball-launching switch 22 is provided in the form of a lever located on the top surface of the casing 11. The ball-launching switch 22 allows manual activation of the impeller mechanism 24 when the player is positioned near the device 11. An impeller calibrating switch 23 is located proximal to the ball-launching switch 22 and allows the user to adjust the rotational speed of the impeller mechanism 24, thereby controlling the launch distance. The calibrating switch 23 enables fine-tuning of the ball delivery distance so that the ball 14 consistently arrives at a desired position on the playing surface.

[0040] The impeller mechanism 24, best seen in the exploded view of FIG. 1, is the core propulsion system of the device 11. The impeller mechanism 24 extends integrally from the housing and comprises a servo-motor and an impeller wheel having a plurality of vanes. The servo-motor is electronically controlled by the microprocessor to rotate the impeller wheel at a calibrated speed. When a billiard ball 14 is held in the ball cradle 12 and the launch is activated, the impeller wheel engages the ball 14 and propels it outward from the device11 along the off-ramp 28 and onto the playing surface. The use of an electronically controlled impeller mechanism 24, as opposed to gravity-fed systems found in the prior art, provides precise and repeatable ball propulsion that can be calibrated to deliver balls at consistent distances.

[0041] A remote control unit 26 is provided for wireless operation of the device 11. The remote control unit 26 includes an activation button and communicates with the microprocessor within the casing 11 via a wireless protocol such as, in non-limiting examples, infrared, Bluetooth, or radio frequency. The remote control unit 26 enables the player to trigger ball launches from their shooting position at the table, eliminating the need to walk to the device 11 between shots. This feature is particularly advantageous during repetitive practice sessions, as it allows the player to maintain their stance, grip, and focus between consecutive shots.

[0042] Referring now to FIGS. 1, 3A, 3B, 4A, and 4B, the multi-component ramp system of the device 11 will be described in detail. The ramp system is designed to store a plurality of billiard balls (up to approximately twelve balls in the illustrated embodiment) and to feed them sequentially and automatically to the ball cradle 12 for launching.

[0043] The ramp system comprises three principal components: a lower ramp component 30, an upper ramp component 32, and a curved ramp 34 connecting the upper and lower ramp components. The lower ramp component 30 is secured to the ball cradle 12 and provides a guided pathway for balls to travel from the ramp system into the launch position. The upper ramp component 32 is attached to the casing 11 and extends upward at an incline, providing a storage area where multiple balls can be lined up in a queue under the influence of gravity. As best seen in FIG. 4B, the billiard balls 14 are arranged in a single-file line along the upper ramp 32, with each ball resting against the next.

[0044] The curved ramp 34 connects the upper ramp component 32 to the lower ramp component 30, providing a smooth transition path that directs the balls from the storage area down to the ball cradle 12. The curved ramp 34 is configured with a sufficient radius to prevent ball jamming while maintaining a controlled feed rate. After each ball 14 is launched from the ball cradle 12, the next ball in the queue automatically gravitates down through the curved ramp 34 and into the vacated ball cradle 12, positioning itself for the next launch. This automated feeding eliminates the need for the player to manually reload the device between shots.

[0045] FIGS. 3A and 3B illustrate different configurations of the ramp system. FIG. 3A shows an extended ramp assembly suitable for storing a greater number of balls, while FIG. 3B shows a more compact configuration. The modular nature of the ramp components allows the user to select the configuration best suited to their practice needs and the available space.

[0046] Referring now to FIG. 5, there are shown multiple interchangeable ball off-ramps 28 having varying exit angles. In the preferred embodiment, at least three different off-ramp configurations are provided: a straight (0-degree) off-ramp, a 15-degree angled off-ramp, and a 25-degree angled off-ramp. Each off-ramp 28 is selectively and removably attachable to the output end of the ball cradle 12. The off-ramps 28 feature a curved upper surface that smoothly guides the launched ball as it exits the ball cradle 12 and transitions onto the playing surface.

[0047] The provision of interchangeable off-ramps 28 allows the user to direct launched balls to different areas of the billiard table without physically repositioning the device 11. For example, a straight off-ramp directs the ball in a line directly away from the device 11, while the 15-degree and 25-degree off-ramps deflect the ball to the left or right, enabling practice of shots from various angles. The off-ramps 28 are designed to provide a gentle transition that places the ball onto the felt playing surface without bouncing or damaging the table cloth.

[0048] In operation, the device 11 is used as follows. The user first ensures the battery 18 is fully charged and activates the device using the on / off switch. The user then positions the device 11 at a desired location on the billiard table and selects and attaches the appropriate off-ramp 28 for the desired ball trajectory. A plurality of billiard balls 14 is loaded onto the upper ramp 32, where they queue under gravity. The first ball gravitates through the curved ramp 34 and into the ball cradle 12.

[0049] The user may then calibrate the launch distance using the impeller calibrating switch 23, making test launches and adjusting until the ball 14 consistently arrives at the desired position on the table. Once calibrated, the user takes their shooting position and uses either the ball-launching switch 22 on the casing 11 or the remote control unit 26 to launch the ball 14. After practicing the shot, the player uses the remote control unit 26 to launch the next ball 14, which has automatically fed into the ball cradle 12 from the ramp system. This process is repeated for as many shots as desired, with the player able to maintain their position and focus throughout the entire practice session.

[0050] The combination of electronically controlled impeller-based propulsion, automated multi-ball feeding, interchangeable angled off-ramps, microprocessor-controlled calibration, and wireless remote operation represents a significant advancement over the prior art. Unlike the gravity-fed, manually operated devices of the prior art, the present invention provides a fully automated, precisely controllable practice tool that maximizes the efficiency and effectiveness of billiard practice sessions.

[0051] It should be understood that the present invention is not limited to the specific embodiments described herein. Modifications and variations are possible without departing from the spirit and scope of the invention. For example, the device may be adapted for use with different sizes of billiard balls, including standard pool balls, snooker balls, and carom billiard balls. The wireless communication protocol between the remote control and the device may employ any suitable technology. Additional off-ramp angles may be provided beyond those specifically described. The ramp system may be configured to store different numbers of balls depending on the embodiment.

[0052] Although the invention has been described in considerable detail in language specific to structural features, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific features described. Rather, the specific features are disclosed as exemplary preferred forms of implementing the claimed invention. Stated otherwise, it is to be understood that the phraseology and terminology employed herein, as well as the abstract, are for the purpose of description and should not be regarded as limiting. Therefore, while exemplary illustrative embodiments of the invention have been described, numerous variations and alternative embodiments will occur to those skilled in the art. Such variations and alternate embodiments are contemplated, and can be made without departing from the spirit and scope of the invention.

[0053] It should further be noted that throughout the entire disclosure, the labels such as left, right, front, back, top, bottom, forward, reverse, clockwise, counter clockwise, up, down, or other similar terms such as upper, lower, aft, fore, vertical, horizontal, oblique, proximal, distal, parallel, perpendicular, transverse, longitudinal, etc. have been used for convenience purposes only and are not intended to imply any particular fixed direction or orientation. Instead, they are used to reflect relative locations and / or directions / orientations between various portions of an object.

[0054] In addition, reference to “first,”“second,”“third,” and etc. members throughout the disclosure (and in particular, claims) are not used to show a serial or numerical limitation but instead are used to distinguish or identify the various members of the group.

[0019] It is another advantage of the present invention that the compact, rectangular housing is designed to sit at the edge of or on the rail of a billiard table, occupying minimal space while providing full functionality including ball storage, feeding, launching, and angle adjustment capabilities.

[0020] According to a first broad aspect of the present invention, there is provided a billiard ball launching device comprising: a housing defining a rectangular casing; a ball cradle extending integrally from the casing and dimensioned to receive and hold a single billiard ball prior to launch; an electronically controlled impeller mechanism extending integrally from the housing and operatively positioned to engage a billiard ball held in the ball cradle, the impeller mechanism being operable to propel the billiard ball from the ball cradle and onto a playing surface at a controlled distance; a multi-component ramp system connected to the housing for storing a plurality of billiard balls and sequentially feeding the billiard balls to the ball cradle, the ramp system comprising a lower ramp component secured to the ball cradle, an upper ramp component attached to the housing, and a curved ramp connecting the upper ramp component to the lower ramp component; and a remote control unit in wireless communication with the housing for remotely activating the impeller mechanism.

[0032] The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the general principles of the present invention have been defined herein.

[0033] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. The terms “a” or “an,” as used herein, are defined as to mean “at least one”. The term “plurality,” as used herein, is defined as two or more. The term “another,” as used herein, is defined as at least a second or more. The terms “including” and / or “having,” as used herein, are defined as comprising (i.e., open language). The term “coupled,” as used herein, is defined as connected, although not necessarily directly, not necessarily mechanically, and not permanent. The term “providing” is defined herein in its broadest sense, e.g., bringing / coming into physical existence, making available, and / or supplying to someone or something, in whole or in multiple parts at once or over a period of time. As used herein, the terms “about”, “generally”, or “approximately” apply to all numeric values, whether or not explicitly indicated. These terms generally refer to a range of numbers that one of skill in the art would consider near the stated amount by about 0%, 5%, or 10%, including increments therein. In many instances these terms may include numbers that are rounded to the nearest significant figure.

[0034] Referring now to the drawings, and more particularly to FIG. 1, there is shown a billiard ball launching device, generally designated by reference numeral 11, according to a preferred embodiment of the present invention. The device 11 is designed to be positioned at the edge of a billiard table and is operative to automatically store, feed, and launch billiard balls 14 onto the playing surface at controlled distances and angles.

[0035] The device 11 comprises a rectangular casing 11 which serves as the main housing unit. The casing 11 is preferably constructed from a durable, lightweight material such as high-impact plastic or aluminum, and is dimensioned to sit stably on or adjacent to a billiard table rail. The casing 11 is inscribed with the trade designation “O.B. Spotter” in the illustrated embodiment.

[0036] A ball cradle 12 extends integrally from the casing 11 and is dimensioned and configured to receive and hold a single billiard ball 14 in a launch-ready position. The ball cradle 12 is connectable to the casing 11 by a snap-fit engagement, as best seen in the exploded view of FIG. 1. The ball cradle 12 is shaped to conform to the curvature of a standard billiard ball (approximately 2.25 inches in diameter for pool, or 2.0625 inches for snooker) and securely holds the ball 14 in alignment with the impeller mechanism 24 prior to launch. As best seen in FIG. 4B, the ball cradle 12 positions the ball 14 at the correct height and orientation for consistent launching.

[0037] The device 11 is powered by a removable rechargeable lithium battery 18 which is received in a battery holder 19 within the casing 11. As shown in FIG. 2, the battery 18 and battery holder 19 are accessible for battery replacement or removal. The battery 18 is rechargeable externally using a charging cable provided with the device, and no charging circuitry is integrated into the casing 11. An on / off switch (not shown) is disposed on a side of the casing 11 for powering the device on and off.

[0038] An internal microprocessor (not shown) is housed within the casing 11 and controls all electronic operations of the device 11. The microprocessor manages the impeller speed, processes signals from the remote control unit 26, and coordinates the launch sequence. The microprocessor is programmed to store and recall calibration settings, enabling the device 11 to deliver balls to a consistent position on the playing surface.

[0039] Referring still to FIG. 1, a ball-launching switch 22 is provided in the form of a lever located on the top surface of the casing 11. The ball-launching switch 22 allows manual activation of the impeller mechanism 24 when the player is positioned near the device 11. An impeller calibrating switch 23 is located proximal to the ball-launching switch 22 and allows the user to adjust the rotational speed of the impeller mechanism 24, thereby controlling the launch distance. The calibrating switch 23 enables fine-tuning of the ball delivery distance so that the ball 14 consistently arrives at a desired position on the playing surface.

[0040] The impeller mechanism 24, best seen in the exploded view of FIG. 1, is the core propulsion system of the device 11. The impeller mechanism 24 extends integrally from the housing and comprises a servo-motor and an impeller wheel having a plurality of vanes. The servo-motor is electronically controlled by the microprocessor to rotate the impeller wheel at a calibrated speed. When a billiard ball 14 is held in the ball cradle 12 and the launch is activated, the impeller wheel engages the ball 14 and propels it outward from the device11 along the off-ramp 28 and onto the playing surface. The use of an electronically controlled impeller mechanism 24, as opposed to gravity-fed systems found in the prior art, provides precise and repeatable ball propulsion that can be calibrated to deliver balls at consistent distances.

[0041] A remote control unit 26 is provided for wireless operation of the device 11. The remote control unit 26 includes an activation button and communicates with the microprocessor within the casing 11 via a wireless protocol such as, in non-limiting examples, infrared, Bluetooth, or radio frequency. The remote control unit 26 enables the player to trigger ball launches from their shooting position at the table, eliminating the need to walk to the device 11 between shots. This feature is particularly advantageous during repetitive practice sessions, as it allows the player to maintain their stance, grip, and focus between consecutive shots.

[0042] Referring now to FIGS. 1, 3A, 3B, 4A, and 4B, the multi-component ramp system of the device 11 will be described in detail. The ramp system is designed to store a plurality of billiard balls (up to approximately twelve balls in the illustrated embodiment) and to feed them sequentially and automatically to the ball cradle 12 for launching.

[0043] The ramp system comprises three principal components: a lower ramp component 30, an upper ramp component 32, and a curved ramp 34 connecting the upper and lower ramp components. The lower ramp component 30 is secured to the ball cradle 12 and provides a guided pathway for balls to travel from the ramp system into the launch position. The upper ramp component 32 is attached to the casing 11 and extends upward at an incline, providing a storage area where multiple balls can be lined up in a queue under the influence of gravity. As best seen in FIG. 4B, the billiard balls 14 are arranged in a single-file line along the upper ramp 32, with each ball resting against the next.

[0044] The curved ramp 34 connects the upper ramp component 32 to the lower ramp component 30, providing a smooth transition path that directs the balls from the storage area down to the ball cradle 12. The curved ramp 34 is configured with a sufficient radius to prevent ball jamming while maintaining a controlled feed rate. After each ball 14 is launched from the ball cradle 12, the next ball in the queue automatically gravitates down through the curved ramp 34 and into the vacated ball cradle 12, positioning itself for the next launch. This automated feeding eliminates the need for the player to manually reload the device between shots.

[0045] FIGS. 3A and 3B illustrate different configurations of the ramp system. FIG. 3A shows an extended ramp assembly suitable for storing a greater number of balls, while FIG. 3B shows a more compact configuration. The modular nature of the ramp components allows the user to select the configuration best suited to their practice needs and the available space.

[0046] Referring now to FIG. 5, there are shown multiple interchangeable ball off-ramps 28 having varying exit angles. In the preferred embodiment, at least three different off-ramp configurations are provided: a straight (0-degree) off-ramp, a 15-degree angled off-ramp, and a 25-degree angled off-ramp. Each off-ramp 28 is selectively and removably attachable to the output end of the ball cradle 12. The off-ramps 28 feature a curved upper surface that smoothly guides the launched ball as it exits the ball cradle 12 and transitions onto the playing surface.

[0047] The provision of interchangeable off-ramps 28 allows the user to direct launched balls to different areas of the billiard table without physically repositioning the device 11. For example, a straight off-ramp directs the ball in a line directly away from the device 11, while the 15-degree and 25-degree off-ramps deflect the ball to the left or right, enabling practice of shots from various angles. The off-ramps 28 are designed to provide a gentle transition that places the ball onto the felt playing surface without bouncing or damaging the table cloth.

[0048] In operation, the device 11 is used as follows. The user first ensures the battery 18 is fully charged and activates the device using the on / off switch. The user then positions the device 11 at a desired location on the billiard table and selects and attaches the appropriate off-ramp 28 for the desired ball trajectory. A plurality of billiard balls 14 is loaded onto the upper ramp 32, where they queue under gravity. The first ball gravitates through the curved ramp 34 and into the ball cradle 12.

[0049] The user may then calibrate the launch distance using the impeller calibrating switch 23, making test launches and adjusting until the ball 14 consistently arrives at the desired position on the table. Once calibrated, the user takes their shooting position and uses either the ball-launching switch 22 on the casing 11 or the remote control unit 26 to launch the ball 14. After practicing the shot, the player uses the remote control unit 26 to launch the next ball 14, which has automatically fed into the ball cradle 12 from the ramp system. This process is repeated for as many shots as desired, with the player able to maintain their position and focus throughout the entire practice session.

[0050] The combination of electronically controlled impeller-based propulsion, automated multi-ball feeding, interchangeable angled off-ramps, microprocessor-controlled calibration, and wireless remote operation represents a significant advancement over the prior art. Unlike the gravity-fed, manually operated devices of the prior art, the present invention provides a fully automated, precisely controllable practice tool that maximizes the efficiency and effectiveness of billiard practice sessions.

[0051] It should be understood that the present invention is not limited to the specific embodiments described herein. Modifications and variations are possible without departing from the spirit and scope of the invention. For example, the device may be adapted for use with different sizes of billiard balls, including standard pool balls, snooker balls, and carom billiard balls. The wireless communication protocol between the remote control and the device may employ any suitable technology. Additional off-ramp angles may be provided beyond those specifically described. The ramp system may be configured to store different numbers of balls depending on the embodiment.

[0052] Although the invention has been described in considerable detail in language specific to structural features, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific features described. Rather, the specific features are disclosed as exemplary preferred forms of implementing the claimed invention. Stated otherwise, it is to be understood that the phraseology and terminology employed herein, as well as the abstract, are for the purpose of description and should not be regarded as limiting. Therefore, while exemplary illustrative embodiments of the invention have been described, numerous variations and alternative embodiments will occur to those skilled in the art. Such variations and alternate embodiments are contemplated, and can be made without departing from the spirit and scope of the invention.
