摘要： 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.

摘要： A counterbalanced ramp assembly includes a ramp portion coupled for reciprocating motion between a stowed position, a deployed position, and a neutral position. First and second elements are operatively coupled to the ramp portion. When the ramp portion moves from the neutral position toward the deployed position, the first element moves a first end of a spring toward a second end of the spring as the second end of the spring maintains a fixed position. When the ramp portion moves from the neutral position toward the stowed position, the second element moves the second end of the spring toward the first end of the spring as the first end of the spring maintains a fixed position.

摘要： A wheelchair lift assembly is provided. The wheelchair lift assembly is adapted to be disposed in a cavity located below a lower surface when in a stowed position. The wheelchair lift assembly includes a lift platform and a lifting mechanism coupled to the lift platform for reciprocating the lift platform between a lowered position, wherein the lift platform is substantially coplanar with the lower surface, and a raised position, wherein the lift platform is substantially coplanar with an upper surface. The wheelchair lift assembly also includes a lift platform barrier coupled to one end of the lift platform and a lift platform barrier actuating assembly coupled to the lift platform barrier. The lift platform barrier actuating assembly actuates the lift platform barrier between a retracted position, wherein the lift platform barrier is disposed substantially flush or below the lift platform to permit access to the lift platform, and an extended position, wherein at least a portion of the lift platform barrier extends above the lift platform to impede access to the lift platform.

摘要： A latch assembly is suitable for a ramp assembly, the ramp assembly having a ramp portion coupled to a fixed portion so that the ramp portion reciprocates between a stowed position and a deployed position. The latch assembly includes a latch pin attached to the ramp portion. The latch assembly further includes a latch fitting coupled to the fixed portion of the ramp assembly. The latch fitting has a hook portion and a tang. The latch fitting selectively reciprocates between a first position, a second position, and a third position.

摘要： A counterbalanced ramp assembly includes a ramp portion coupled for reciprocating motion between a stowed position, a deployed position, and a neutral position. A first biasing element is coupled to a first endless loop and compresses a first spring when the ramp portion moves from the neutral position toward the deployed position. The first biasing element is disengaged from the first spring when the ramp portion is located between the neutral position and the stowed position. A second biasing element is coupled to the second endless loop and compresses a second spring when the ramp portion moves from the neutral position toward the stowed position. The second biasing element is disengaged from the second spring when the ramp portion is located between the neutral position and the deployed 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.
