Patent number: 10252449Abstract: A method of incorporating a preformed shape into a rotational molded product by a method that comprises the steps of a) forming a first resin into an uncured preformed shape having perimeter edges; b) positioning the uncured preformed shape having perimeter edges against an inside wall of a rotational mold; c) adding a second resin into the rotational mold; heating and rotating the rotational mold to form the rotational molded product, wherein said second resin binds to the perimeter edges of the preformed shape and the preformed shape becomes cured. The invention also relates to a rotationally molded product that has a preformed shape made of a first resin incorporated into an object or vessel made of a second resin, wherein the preformed shape is integral with the object or vessel.Type: GrantFiled: January 20, 2016Date of Patent: April 9, 2019Assignee: Centro, Inc.Inventors: David G. Surridge, Daniel D. Grimes

Patent number: 8939490Abstract: An off-road utility vehicle with a reconfigurable cargo bed with fore and aft sections joined to the vehicle. Each section has three walls and a floor. The fore section pivots with respect to the aft section between an open position and a closed position with the fore section on top of the aft section. In the closed position, the reconfigurable cargo bed is a container with an opening in the foremost side of the container. A movable bulkhead is provided that is adapted to close the opening of the foremost side of the container, as well as being repositionable to serve as an extended surface for hauling cargo, a work bench that extends from a side of the cargo bed, or as a divider in the center of the cargo bed.Type: GrantFiled: June 28, 2012Date of Patent: January 27, 2015Assignee: Centro, Inc.Inventor: David G. Surridge

Patent number: 8911842Abstract: A multiple walled enclosure with low permeation properties and rugged impact resistance useful as a fuel tank or chemical container. The enclosure is made by rotomolding a first charge of thermosetting polymer into an outer layer, then rotomolding a charge of EVOH or other low permeation thermoplastic into a second layer, then rotomolding a second charge of thermosetting polymer into a third layer so that the low permeation thermoplastic layer is fully enclosed by layers of thermoset polymer. The preferred thermosetting polymer is crosslinkable polyethylene and the preferred low permeation thermoplastic is EVOH.Type: GrantFiled: October 18, 2013Date of Patent: December 16, 2014Assignee: Centro, Inc.Inventors: Alvin G. Spence, Jeremy R. Knepper, Daniel D. Grimes
