| 20100051412 | Roller For Attaching to an Axle of a Conveying or Storage Device to Aid in the Transport of an Object - A roller for positioning on a member of a conveying or transportation device where the member acts as a stationary axle for the roller includes an outer shell typically constructed from a compressible thermoplastic, rubber or polymeric material and a hollow inner core typically constructed from a rigid thermoplastic or polymeric material. The roller includes a through bore defined by axle engaging ribs where the ribs engage a circumference of the axle substantially perpendicular to an axis of the member such that the roller is rotatable about an axis of the axle. The outer shell is typically molded over the inner rigid shell where the outer shell is of a selected thickness that does not compress over time due to the weight of the boat or watercraft. | 03-04-2010 |
