Rolling pool bridge

Abstract

A rolling bridge is provided that includes a single wheel having a length greater than its diameter. The rolling bridge includes a chassis positioned to cover at least a portion of the single wheel and having at least two forks that extend along opposite ends of the wheel. An axle secures the wheel to the forks of the chassis and allows rotation of the wheel with respect to the chassis. The chassis includes one or more clip extensions that extend upward to define at least a portion of a substantially cylindrical channel having two open ends and an axis that is orthogonal to the axis of rotation of the wheel. The cylindrical channel is configured to secure the rolling bridge to a pool cue.

What is claimed is: 
     
         1 . A rolling bridge for a pool cue comprising:
 a single wheel having a length and a maximum diameter, wherein the length is greater than the maximum diameter;   a chassis positioned to overlie at least a portion of the single wheel, the chassis comprising at least two forks that extend along opposite ends of the wheel, each of the at least two forks having a portion aligned with an axis of rotation of the wheel, the chassis further comprising one or more clip extensions that define at least a portion of a channel having first and second open ends, wherein the channel is configured to secure the rolling bridge to a pool cue; and   an axle securing the single wheel to the chassis, the axle configured to allow rotation of the wheel with respect to the chassis.   
     
     
         2 . The rolling bridge of  claim 1 , wherein the single wheel has a substantially constant diameter. 
     
     
         3 . The rolling bridge of  claim 1 , wherein the channel is substantially cylindrical. 
     
     
         4 . The rolling bridge of  claim 1 , wherein the channel has a central axis that is orthogonal to the axis of rotation of the wheel. 
     
     
         5 . The rolling bridge of  claim 4 , wherein the one or more clip extensions are configured to flex around the central axis of the channel to secure variable diameter pool cues to the rolling bridge. 
     
     
         6 . The rolling bridge of  claim 2 , wherein the maximum diameter of the single wheel is about one inch. 
     
     
         7 . The rolling bridge of  claim 1 , wherein the length of the single wheel is greater than one inch and smaller than two inches. 
     
     
         8 . The rolling bridge of  claim 1 , wherein the channel is tapered from the first open end to the second open end. 
     
     
         9 . The rolling bridge of  claim 3 , wherein the substantially cylindrical channel has a maximum diameter along its length and the length of the single wheel is at least double the maximum diameter of the substantially cylindrical channel. 
     
     
         10 . The rolling bridge of  claim 3 , wherein the single wheel has a substantially constant diameter, and wherein the substantially cylindrical channel has a diameter that is substantially equal to the maximum diameter of the single wheel. 
     
     
         11 . The rolling bridge of  claim 1 , wherein the chassis comprises two clip extensions and each of the two clip extensions is positioned equidistant from a center point between the two forks of the chassis. 
     
     
         12 . The rolling bridge of  claim 1 , wherein the axle comprises a first portion that secures a first end of the wheel to a first fork and a second portion that secures a second end of the wheel to a second fork. 
     
     
         13 . The rolling bridge of  claim 12 , wherein the first portion of the axle is secured to the first fork with a first pin and the second portion of the axle is secured to the second fork with a second pin. 
     
     
         14 . The rolling bridge of  claim 1 , wherein the portion of each fork that is aligned with an axis of rotation of the wheel comprises a through hole. 
     
     
         15 . The rolling bridge of  claim 1 , wherein the portion of each fork that is aligned with an axis of rotation of the wheel comprises a recess. 
     
     
         16 . The rolling bridge of  claim 1 , wherein the single wheel has a variable diameter. 
     
     
         17 . The rolling bridge of  claim 16 , wherein the single wheel has a first end portion, a second end portion, and a central portion positioned between the first end portion and the second end portion, each of the first end portion, the second end portion, and the central portion having respective diameters, wherein the diameter of the first end portion and the diameter of the second end portion are equal to each other, and wherein the diameter of the central portion varies to define a recess. 
     
     
         18 . The rolling bridge of  claim 17 , wherein the channel is substantially cylindrical. 
     
     
         19 . The rolling bridge of  claim 18 , wherein the substantially cylindrical channel has a maximum diameter along its length and the length of the single wheel is at least double the maximum diameter of the substantially cylindrical channel. 
     
     
         20 . The rolling bridge of  claim 17 , wherein the single wheel has a minimum diameter, and wherein the substantially cylindrical channel has a diameter that is substantially equal to the minimum diameter of the single wheel.
