Title:
GRAVITY CONVEYOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/138682
Kind Code:
A3
Abstract:
A gravity conveyor assembly includes first and second track assemblies positioned parallel to each other. Each of the track assemblies includes a body, having a slot in a first surface. A track member includes a frictional engagement portion received and frictionally engaged within the slot. A track extending portion freely extends above the first surface of the body. The track extending portion is oriented at an angle with respect to an axis oriented transverse to a ground surface such that the track extending portion has a continuous slope with respect to the ground surface. A cassette supported on the first and second track members is adapted for gravity induced rolling motion by the continuous slope. Wheels mounted to opposed sides of the cassette each have a concave perimeter surface aligned for rolling contact with the track extending portion of the track assemblies.
