Wheels are mounted to the bottom of the bin at the four corner regions thereof, the wheels being positioned for enabling the roll-off box to be rolled in a longitudinal direction. First and second rollers, which are smaller in diameter than the wheels, are mounted to bottom regions of the bin adjacent to one of its ends, each of the rollers being positioned outboard of a corresponding wheel and directly beneath an associated one of the bin sides. The rollers are mounted so that their peripheries are above the peripheries of the wheels. Plates are fixed to each side of the bin outboard of the rollers, the plates extending downwardly below lower regions of the rollers. An upwardly-opening roller-receiving recess is provided in upper regions of each of the bin sides above the rollers, the recesses being ramp shaped at one end.Type: GrantFiled: June 13, 1990Date of Patent: February 4, 1992Inventor: Don B.

Patent number: 5020814Abstract: A collapsible bicycle trailer includes a rigid chassis frame, hinged side rails, a side rail locking bar, a hinged tongue, and quick release wheels. The chassis frame has a generally rectangular-shaped outer frame member, and inner frame members spaced inwardly from and parallel to, the sides of the outer frame member, with wheels rotating between the outer and inner frame members. On each side of the chassis frame are positioned a pair of side rail hinge members to which are attached the lower ends of the side rails which rotate between an extended, vertical position and a folded horizontal position. The side rail hinge members also are designed to provide the connecting means between the outer and inner frame members. A side rail locking bar is pivotally attached to the top of one side rail and unfolds to securely connect to the top of the other side rail, forming a roll bar assembly.Type: GrantFiled: June 11, 1990Date of Patent: June 4, 1991Assignee: Burley Design CooperativeInventors: Donald A. George, Peter B. Berry, Bruce W. Creps, Geraldine C. Roles

Patent number: 4946332Abstract: A trailer capable of carrying a boat and vehicle in a dual load mode of operation wherein the boat is mounted rearwardly of the vehicle in an inclined position with the bow of the boat above portions of the vehicle being carried. The trailer is also convertible into a single load mode of operation wherein the boat is carried low in a conventional orientation by lowering a supporting boat carriage into a collapsed position near the frame of the trailer. The trailer is provided with a boat carriage which is connected to the frame of the trailer and supported by a lifting mechanism which causes the boat carriage and any supported boat to shift rearwardly when they are moved from the collapsed position into the extended raised position. This rearward movement automatically shifts the weight of the boat carriage and any supported boat rearwardly to counteract the loading associated with a vehicle on forward portions of the trailer.Type: GrantFiled: September 20, 1988Date of Patent: August 7, 1990Inventor: Lewis D. Daniels

Patent number: 4772038Abstract: Trailer of the type which can be widened out or retracted when required, made of a frame on which there is mounted a wheel assembly. The frame comprises a traction bar, a rear transverse member fixedly mounted at one end of the traction bar, a front traction member which is parallel to the rear traction member and is also fixedly mounted on the traction bar, along the latter, short of its opposed end. The portion of the traction bar between the front transverse member and the opposed end thereof constitutes a traction rod. A movable framework is disposed on both sides of the traction bar between the rear and front transverse members. The wheels of the trailer are mounted on the movable frameworks, which can laterally extend thereby widening out the trailer, or they can be retracted in the narrow position of the trailer. This trailer can easily be attached to a four- or three-wheeler of the sporting type and, when it is widened out, it can be used to carry the four- or three-wheelers.Type: GrantFiled: June 17, 1987Date of Patent: September 20, 1988Inventor: Nelson MacDonald

Patent number: 4763914Abstract: A trailer is provided including an elongated longitudinally extending frame incorporating longitudinally aligned and extending front and rear frame sections pivotally secured together at adjacent ends for free relative angular displacement about a horizontal transverse axis. The front end of the front frame section includes coupling structure for coupling the frame to a towing vehicle and the rear frame section includes a transverse axle assembly mounted from the rear frame section centrally intermediate its opposite ends and having a pair of opposite side ground engaging support wheels journalled therefrom. Further, the rear frame section includes structure for support and cradling the lower periphery of the rear wheel of a motorcycle in position rearward of the axle assembly and the front frame section of the trailer includes motorcycle front wheel supporting and cradling structure supported therefrom for adjustable shifting longitudinally of the front frame section.Type: GrantFiled: June 25, 1987Date of Patent: August 16, 1988Inventor: Albert G. Lemmons

Patent number: 4611962Abstract: A container chassis bundling system uses permanently affixed clamps 14, 14a, 40, 42, 42a, or 42b, for example, placed on a container chassis 10 to interconnect container chassis into an integral stack of chassis. Usually, chassis are interconnected with corresponding twist-lock bayonets 18 and twist-lock receivers 12 between corresponding top surfaces of the chassis and either rail 42, 42a, or 42b or landing gear interconnections 14 or 14a between the rails on the bottom flanges of the other chassis. An axle clamp 40 may connect the axle of one chassis to the kingpin of another chassis. Rail clamps 42, 42a, or 42b may also be used to connect corresponding top surfaces.Type: GrantFiled: March 22, 1984Date of Patent: September 16, 1986Inventors: John L. Braly, Randall W. Matthewson

Patent number: 4602399Abstract: A bridge carrying and launching trailer includes a tilt frame mounted to a trailer frame. The tilt frame includes a foot portion which rests upon the ground when launching a bridge. The trailer relies upon the weight of another vehicle to counter the moment caused by launching an unfolding type military bridge. One or more control cables extend from the trailer to the other vehicle, preferably an armored vehicle such as a tank, to allow remote control of the bridge launching sequence. The trailer includes a redundant hydraulic system and mechanical components such that a bridge may be launched even if one of the two hydraulic systems is damaged. The bridge launching trailer is especially adapted to fit in compact places such as an airplane cargo bay.Type: GrantFiled: May 24, 1984Date of Patent: July 29, 1986Assignee: Harsco CorporationInventor: Arthur B.
