Patent number: 5007794Abstract: A load-carrying attachment for a vehicle to unload cargo from or load cargo onto the vehicle. The attachment includes a pair of spaced horizontal support beam assemblies having first and second ends. A cross beam connects the first ends of the beam assemblies to form a fixed frame with the beam assemblies. The cross beam is attachable to the vehicle such that the assembly is movable along the periphery of the vehicle. The attachment includes a pair of leg members, one of the leg members being attached to one of the support beam assemblies. The leg members include hydraulic cylinders for raising and lowering the support beam assemblies and wheel assemblies which can be employed as wheels when moving the attachment or as bases when the attachment is being employed to load or unload cargo. The attachment further includes a mast which is slidably attached to the beam assemblies such that it is movable along the beam assemblies. The mast is positioned between the beam assemblies.Type: GrantFiled: April 27, 1989Date of Patent: April 16, 1991Assignee: Luis A. FigueroaInventor: Jose O. Lombard

Patent number: 4978271Abstract: The invention relates to a vehicular apparatus for use in handling recycleable material which includes a pair of end-to-end first containers supported on each side of the vehicle and each having a side opening into which such material may be loaded at a place of connection, and a pair of second and larger containers supported on the vehicle above and intermediate the pairs of first containers and each having a top opening to receive material from a first container. Each pair of first containers are adapted to be moved together between their loading positions and unloading positions in which the side opening in each is arranged to dump material therefrom into the top opening in a second container, and each of the second containers is adapted to be moved independently of the other between its loading position and an unloading position in which its top opening is arranged to dump material therefrom onto a place of disposal at the side of the vehicle.Type: GrantFiled: July 6, 1989Date of Patent: December 18, 1990Assignee: Western Disposal, Inc.Inventor: Jack G. Seader

Patent number: 4958979Abstract: Arrangement for a lift adapted to a motor vehicle, comprising a lifting platform capable of moving between the vehicle and a floor. The invention provides a simple device for achieving a reliable and efficient lift arrangement, for example, for use by individuals in wheelchairs who wish to move between the inside and the outside of a vehicle without the help of an assistant, and without additional ramp or lift arrangements. The platform is attached via a scissor mechanism to a source of power for the platform, so that the platform, upon actuation of the power source, moves between a lower and an upper position, one of which at least is situated at a different level with respect to that of the attachment of the scissor mechanism to the source of power.Type: GrantFiled: April 19, 1989Date of Patent: September 25, 1990Inventor: Ingemar Svensson

Patent number: 4909700Abstract: The lift is installed under the cargo floor proximate to the side door of the van. In the retracted position it is entirely concealed and does not obstruct the normal van usage. Stationary track members are attached to the van. Slidably mounted within the track members are frame members which may be extended or retracted from the van by use of a pair of worm gears. A pair of hydraulic cylinders interconnect the platform and the frame using four links which raise and lower the platform equalangularly. The equalangular motion of the links maintains the platform in a substantially horizontal position as it is lowered from its raised position level with the floor of the van to its lower position with the street or sidewalk.Type: GrantFiled: February 3, 1989Date of Patent: March 20, 1990Assignee: Invercan, Inc.Inventors: Bruce E. Fontecchio, Adolf Spiegelhalter

Patent number: 4836736Abstract: A main frame pivotally supports the forward ends of a laterally spaced apart pair of parallelogram linkage systems. Each linkage system comprises an upper link and a two section lower link, rear ends of which are pivotally interconnected to a rear shackle, the lower end of which has a ground engageable roller. A load platform is pivotally connected along its forward edge to the rear ends of the upper links. The rear sections of the lower links are rigidly interconnected by a lift frame that is fitted at its opposite ends with upstanding crank members. A hydraulic piston cylinder mechanism is mounted adjacent each linkage system with its butt end pivotally connected to the main frame and the piston rod of each cylinder is pivotally connected to one of the upstanding crank members. The forward and rear sections of each lower link are pivotally interconnected by a knuckle pin and each lower link includes stops to bidirectionally limit relative angular displacement of the two sections.Type: GrantFiled: June 9, 1987Date of Patent: June 6, 1989Assignee: Maxon Industries, Inc.Inventor: Alexandru Neagu

Patent number: 4763487Abstract: A refrigerated mobile cargo container having side and rear platforms for loading and unloading cargo and hydraulic control valves for regulating the raising and lowering of the platforms. Fluid to the control valves can be supplied from either a primary pump system powered by the refrigeration unit prime mover or by a secondary pump system powered by a twelve volt power supply. Each pump system has its own fluid reservoir. Check valves are provided which prevent the fluid from one pump system from being passed into the other pump system.Type: GrantFiled: May 4, 1987Date of Patent: August 16, 1988Assignee: Ralph W. Earl Company, Inc.Inventor: Robert G. Wicks

Patent number: 4741658Abstract: A lifter for emptying a container into a cavity of a vehicle. The lifter has a first plate pivotally connected to the vehicle, and a second plate extending at an angle from the first plate. The lifter has a third plate slidably mounted on the second plate, with the third plate having a pair of hooks to grasp bars on the container. The lifter moves between a first lower position beneath the truck to a second upper position with the container located above the cavity to empty the container into the cavity.Type: GrantFiled: May 12, 1986Date of Patent: May 3, 1988Assignee: Perkins Manufacturing CompanyInventors: Robert F. Zelinka, John W. Redding

Patent number: 4722651Abstract: A device for attachment to the rear of a pickup truck as a replacement for the rear bumper includes a transverse frame member which is pivotally mounted on brackets carried on the chassis. The frame member carries a pair of arms each of which is pivoted at an outer end of the frame member and extends across the frame member in a folded position with an outer stub portion extending outwardly and around the end of the frame member to define ends of the bumper. Hydraulic rams can pivot the frame member about a horizontal axis and can pivot the arms about vertical axes at the outer ends of the frame member. Flanges extending from the rear face of the frame member confine and receive the arms and define a compartment for a hitch pin.Type: GrantFiled: June 24, 1987Date of Patent: February 2, 1988Inventor: Dean L. Antal

Patent number: 4711613Abstract: A vehicle lift device comprises structure 23 which is fixed to the chassis beneath the vehicle floor 11, a parallel linkage 21 carrying a platform 50 and connected to the structure 23 for movement at a level beneath floor 11 about vertical axis 22 so that the linkage and platform can be moved between an operative position extending from the vehicle and a stowed position beneath the vehicle floor 11. A single ram 40 can move the linkage up and down for raising and lowering a load, for example a wheel-chair, to permit the load to be moved on to the floor through a doorway which is not obstructed by the lift device. The platform can be collapsed for storage and the linkage has nesting members 35a, 37 for resisting possible injury.Type: GrantFiled: April 23, 1984Date of Patent: December 8, 1987Assignee: Henderson Doors LimitedInventor: Percy Fretwell
