Abstract: A retractable guide for loading and unloading snowmobiles, ATVs and other equipment from a trailer or truck bed includes a first portion that is movable relative to a second portion that is fixedly attached to the truck or trailer bed such that the first portion pivotally moves relative to the second portion. The first portion is of a sufficient length such that when the first portion guide is in an extended position a distal edge of the first portion contacts the ground surface to provide a ramp for loading and unloading the ATV, snowmobile or other equipment. The ramp provides a smooth transition from the ground to the bed of the truck or trailer. Once the ATV, snowmobile or other equipment is loaded onto the bed of the trailer or truck, the first portion of the guide is pivotally positioned into a stowed position such that an end gate or other retaining wall can be positioned into a secured vertical position with the ATV, snowmobile or other equipment being positioned on the bed of the trailer or truck.

Abstract: 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.
