As shown, the rolling pool bridge 100 can comprise a single wheel 70 and a chassis 10 having two forks 50 that extend down along each end of the wheel 70. A bolt axle 110 can extend through a through hole on each fork and through a through hole and extend along an axis of rotation 90 of the wheel 70. The bolt axle 110 couple or secure the wheel 70 to the chassis 10 to form the rolling pool bridge 100. The chassis 10 can also have two clip extensions 30 extending upward from its base 20 to form a cylindrical or substantially cylindrical channel 40. The cylindrical channel 40 is configured to receive a pool cue 200 as shown. In operation, the length of the wheel 70 provides a sturdy base upon which to support the weight of the pool cue 200. The rotation of the wheel 70 in combination with the clip extensions 30 that couple or secure the pool cue 200 to the rolling bridge 100 and position the pool cue 200 above the surface of the pool table facilitates one handed operation of the pool cue 200 during billiards.
Although described herein as having a cylindrical (or substantially cylindrical) channel, it is contemplated that the channel can have any three-dimensional profile (triangular, substantially triangular, rectangular, substantially rectangular, and the like) that is capable of receiving and supporting a portion of a pool cue as disclosed herein. For example, it is contemplated that interior surfaces of the channel can define a cylindrical or substantially cylindrical shape, while exterior surfaces can have rectangular or substantially rectangular profile.
In exemplary aspects, it is contemplated that the wheels of the disclosed rolling pool bridges can comprise a low-friction outer (contact) surface that is configured to promote free movement of the wheel on the playing surface of a billiards table. For example, in these aspects, it is contemplated that nylon can be used to form the wheels or define the outer surface of the wheels. In other exemplary aspects, it is contemplated that the wheel of a rolling pool bridge can comprise an outer (contact) surface (e.g., a tacky surface) that is configured to promote adhesive and/or frictional engagement with the playing surface or side walls of a billiards table. For example, in these aspects, it is contemplated that silicon rubber (e.g., silicon rubber Shore A 45-80) can be used to form the wheels or define the outer surface of the wheels. In some optional aspects, it is contemplated that a kit can comprise a chassis 10 as disclosed herein and a plurality of wheels having different surface engagement materials and/or properties, with each of the wheels being configured for selective engagement with the chassis to permit selective adjustment of the type of wheel used with the chassis.
Optionally, it is contemplated that a plurality of rolling pool bridges as disclosed herein can be available for use by a billiards player. In exemplary aspects, a kit comprising a plurality of rolling pool bridges having a variety of operative heights and or wheel surface properties can be provided. For example, in some aspects, the kit can comprise first and second rolling pool bridges having respective operative heights measured vertically from a bottom (contact) surface of the wheel to a base portion of the channel. In these aspects, it is contemplated that the operative heights of the first and second rolling pool bridges can be different. In exemplary aspects, it is contemplated that an operative height ranging from about 0.5 inch to about 1 inch can be useful for positioning against a side rail of a billiards table (for example, when the cue ball is near the side edge). In further exemplary aspects, it is contemplated that an operative height ranging from about 1 inch to about 2.25 inches can be useful for normal shots, with the rolling pool bridge spaced away from the side rails and the arrangement of balls providing for unobstructed contact between the pool cue and the cue ball. In still further exemplary aspects, it is contemplated that an operative height of equal or greater than 2.25 inches (the standard ball diameter) or ranging from about 2.25 inches to about 3.5 inches can be useful for shots in which it is necessary to pass the pool cue over another ball before contacting the cue ball. As can be appreciated, this increased height can elevate the position of the pool cue and allow the player to avoid contact between the pool cue and the ball that is preventing a conventional shot of the cue ball. Thus, it is contemplated that the disclosed kits can include pool bridges having operative heights falling within two or more of the above-identified ranges. For example, in some aspects, the first rolling pool bridge can have an operative height ranging from about 0.75 inch to about 2.25 inches, and the second rolling pool bridge can have an operative height ranging from about 0.5 inch to about 1 inch. In other aspects, the first rolling pool bridge can have an operative height ranging from about 0.75 inch to about 2.25 inches, and the second rolling pool bridge can have an operative height ranging from about 2.25 inches to about 3.5 inches. In still other aspects, the kit can comprise at least three rolling pool bridges, with the first rolling pool bridge can have an operative height ranging from about 0.75 inch to about 2.25 inches, the second rolling pool bridge having an operative height ranging from about 0.5 inch to about 1 inch, and the third rolling pool bridge having an operative height ranging from about 2.25 inches to about 3.5 inches, thereby providing flexibility in addressing all types of shots that a player may need to complete during a billiards game.
Optionally, in still further aspects, it is contemplated that the rolling bridge chassis 10 can have an adjustable profile. For example, in some aspects, it is contemplated that an operative distance between the interior surfaces of the forks 50, measured along axis of rotation 90, can be selectively adjustable. In these aspects, it is contemplated that one or more of the forks can be coupled to the base such that said one or more forks can selectively translate (in either direction along axis 90) relative to base 20 and/or the channel 40. It is further contemplated that the chassis 10 can comprise a lock or engagement structure that can be selectively opened/disengaged and closed/engaged to selectively adjust or secure the position of said one or more forks. In use, it is contemplated that the adjustable chassis 10 can be used with a plurality of wheels 70 that have different lengths (measured relative to axis 90). For example, following removal of an axle or dowel pin, a first wheel can be disengaged from and then removed from a chassis. After removal of the first wheel, the operative distance between the forks can be adjusted (lengthened or shortened) as described above. With the operative distance properly adjusted, a second wheel having a different (longer or shorter) length than the first wheel can be rotationally coupled to the chassis 10 through an axle or dowel pin as further disclosed herein.
Similarly, in additional aspects, it is contemplated that an operative height of the base 20 and/or the channel 40 can be selectively adjustable. For example, in some aspects, it is contemplated that the base 20 (and the clip extensions 30 and channel 40) can be coupled to the forks 50 such that the base 20 can selectively translate (in either direction along a vertical axis) relative to the forks. It is further contemplated that the chassis can comprise a lock or engagement structure that can be selectively opened/disengaged and closed/engaged to selectively adjust or secure the position of the base 20. In use, it is contemplated that the adjustable chassis 10 can be used with a plurality of wheels 70 that have different heights (measured relative to a vertical axis). For example, following removal of an axle or dowel pin, a first wheel can be disengaged from and then removed from a chassis. After removal of the first wheel, the operative height of the base of the chassis can be adjusted (higher or lower) as described above. With the operative height properly adjusted, a second wheel having a different (taller or shorter) height than the first wheel can be rotationally coupled to the chassis 10 through an axle or dowel pin as further disclosed herein. Alternatively, rather than replacing the wheels and adjusting the height of the base 20 of the chassis, it is contemplated that an operative height of the channel 40 relative to the base 20 can be selectively adjustable. In these aspects, it is contemplated that the size of the wheel can remain consistent while the height of the clip extensions 30 relative to the base 20 can be increased or decreased to provide a desired angle for contacting a cue ball with a pool cue passing through the channel. It is further contemplated that the chassis can comprise a lock or engagement structure that can be selectively opened/disengaged and closed/engaged to selectively adjust or secure the vertical position of the clip extensions 30 and/or the channel 40 relative to the base 20.
