  • Publication number: 20040096304
    Abstract: A wheelchair ramp assembly (20) is disclosed. The wheelchair ramp assembly includes a frame attachable to a vehicle having a floor, a platform coupled to a portion of the frame, a ramp having a weight, and a reciprocating mechanism disposed between the ramp and the platform coupled to a portion of the frame, a ramp having a weight, and a reciprocating mechanism disposed between the ramp and the platform for reciprocating the ramp between a deployed position and a stowed position in response to a force. The reciprocating mechanism counterbalancing the weight of the ramp during actuation of the ramp between the deployed and stowed positions to reduce the force required to reciprocate the ramp between the deployed and stowed positions.

  • Publication number: 20030007853
    Abstract: A ramp assembly (20) for mounting in a low floor bus (22) or other vehicle. The ramp assembly (20) includes a rectangular enclosure (24) that fits underneath the chassis of the low floor bus (22). The ramp assembly (20) includes a reciprocating mechanism (26) for moving a ramp platform (28) between a fully deployed position and a fully stowed position. During this movement, the reciprocating mechanism (26) raises the trailing end of the ramp platform (28) in one translational movement with the extension of the ramp platform, such that the trailing end of the ramp platform, when deployed, is raised to the floor level of the low floor bus (22).

  • Patent number: 6238168
    Abstract: A ramp assembly is provided. The ramp assembly includes a frame, a ramp platform, and first and second locking mechanisms. The ramp platform is mounted in the frame defining forward and trailing ends, and is extendible and retractable along a length of the frame between a stowed and a deployed position. The ramp platform is arranged such that when deployed the forward end extends down towards the ground. The first locking mechanism locks the ramp platform into a fully deployed position, and the second lock mechanism locks the ramp platform into a fully stowed position. The ramp assembly also includes a manual release mechanism, the actuation of which releases the first locking mechanism when the ramp assembly is in the fully deployed position. The actuation of the manual release mechanism also releases the second locking mechanism when the ramp platform is in the fully stowed position.

  • Patent number: 6203265
    Abstract: A ramp assembly is provided. The ramp assembly includes a frame, a ramp platform, a reciprocating mechanism and first and second levers. The ramp platform is mounted in the frame and defines trailing and forward ends. The reciprocating mechanism extends and retracts the ramp platform along a length of the frame between stowed and deployed positions. The ramp platform is arranged when deployed such that the forward end extends down toward the ground. The first lever has a distal end attached to a first side of the trailing end of the ramp platform. The first lever is configured to rotate as the ramp platform is extended, thereby lifting the first side of the trailing end upward. The second lever includes a distal end attached to a second side of the trailing end of the ramp platform. The second lever is configured to rotate as the ramp platform is extended, thereby lifting the second side of the trailing end upward.
