Abstract: A ramp assembly includes a ramp portion configured for reciprocating motion between a stowed position, a deployed position, and a neutral position. A counterbalance comprises a shaft and a crank fixedly coupled to the shaft. A rod is rotatably coupled to the crank with an end fitting, and an end stop is slidably coupled to the rod. A compression spring is disposed between the end fitting and the end stop, wherein the compression spring provides a force to bias the ramp portion toward the stowed position when the ramp portion is between the deployed position and the neutral position, and toward the deployed position when the ramp portion is between the stowed position and the neutral position.

Abstract: A platform-type wheelchair lift for mounting in the stairwell of a vehicle, such as a bus or train. The wheelchair lift includes a platform frame that is movable from a retracted position in which it is stowed underneath the vehicle to an extended position in which it extends out from the side or back of the vehicle. A wheelchair platform is movably coupled to the platform frame by a parallelogram linkage that allows the wheelchair platform to move between a lowered and a raised position. The wheelchair platform includes foldable outer, side, and inner wheelchair barriers that prevent a wheelchair from moving off of the wheelchair platform during operation of the wheelchair lift. The outer and inner wheelchair barriers are capable of absorbing part of the energy of an impact between a wheelchair and the barriers and in ways cause barriers to fold out.

Abstract: A ramp assembly has a ramp portion configured for reciprocating movement between a stowed position, a deployed position, and a neutral position, and a counterbalance. The counterbalance includes a compression spring and an engagement fitting associated with a first end of the spring. A first bearing element is operably coupled to the ramp portion so that movement of the ramp portion from the neutral position toward the stowed position engages the first bearing element with the engagement fitting to move the first end of the spring toward a second end of the spring. A second bearing element is operably coupled to the ramp portions of that movement of the ramp portion from the neutral position toward the deployed position engages the second bearing element with the engagement fitting to move the first end of the spring toward the second end of the spring.

Abstract: A ramp assembly includes a ramp portion configured for reciprocating motion between a stowed position, a deployed position, and a neutral position. The ramp assembly further includes a counterbalance that provides a force to bias the ramp portion toward the stowed position when the ramp portion is between the deployed position and the neutral position, and toward the deployed position when the ramp portion is between the stowed position and the neutral position. A shaft rotates in a first direction when the ramp portion moves toward the stowed position, and in a second direction opposite the first direction when the ramp portion moves toward the deployed position. A crank is fixedly coupled to the shaft. A rod is rotatably coupled at a first end to the crank about a first axis and at a second end to a cylinder. The cylinder is coupled for rotational movement about a second axis.

Abstract: A ramp assembly has a ramp portion configured for reciprocating motion between a stowed position, a deployed position, and a neutral position. A counterbalance is associated with the ramp portion and includes a drive element with a spring fitting. The drive element is rotatably coupled about a first axis of rotation that moves along an arcuate path. A restraint is slidably coupled to the drive element and is also rotatably coupled about a fixed axis of rotation. An end stop is associated with the restraint. A compression spring is disposed between the spring fitting and a portion of the restraint so that the compression spring provides a force to bias the ramp portion toward the neutral position.

Abstract: A drive assembly (100) for a wheelchair lift is provided. The drive assembly (100) includes an actuating assembly (104) in communication with a component of the wheelchair lift. The actuating assembly (104) is configured to selectively apply a driving force to move the component between at least first and second positions. The drive assembly (100) also includes an overload assembly (102) coupled to the actuating assembly (104). The overload assembly (102) is configured to redirect application of the driving force from the component to the overload assembly (102) when a force applied to the component exceeds a predetermined limit.
