A counterbalance for a ramp assembly includes a chain assembly and a spring assembly. The spring assembly includes a spring and first and second spring fittings. The first spring fitting restrains a first end of the spring when the ramp portion is between a neutral position and the stowed position and moves the first end of the spring toward a second end of the spring when the ramp portion moves from the neutral position toward the deployed position. The second spring fitting is spaced from the first spring fitting and restrains the second end of the spring when the ramp portion is between the neutral position and the deployed position. The second spring fitting moves the second end of the spring toward the first end of the spring when the ramp portion moves from the neutral position toward the stowed position.
A ramp assembly includes a ramp disposed within a vehicle. The ramp assembly further includes a movable floor hingedly coupled at a first end to the ramp. A reciprocating mechanism reciprocates a second end of the movable floor between a lowered position when the ramp is in the stowed position, and a raised position when the ramp is in the deployed position.
A ramp assembly for a vehicle having a floor includes a movable floor at least partially disposed within the vehicle. A ramp support element is rotatably coupled within the vehicle. A ramp portion is coupled at a first end to the ramp support element so that the ramp portion reciprocates between a stowed position a deployed position when the ramp support element rotates. A reciprocating mechanism reciprocates the second end of the movable floor between a lowered position when the ramp is in the stowed position, and a raised position when the ramp is in the deployed position.
A closeout assembly is suitable for use with a ramp assembly disposed within a vehicle having a floor. The ramp assembly includes a ramp portion rotatably coupled at a first end for reciprocating movement between a stowed position and a deployed position. A panel assembly is hingedly coupled to the first end of the ramp portion. The close out assembly includes an end cap hingedly coupled at a first end to the first end of the ramp portion. A link is hingedly coupled at a first end to a second end of the end cap. A second end of the link is hingedly coupled to the panel assembly. When the ramp portion reciprocates between the stowed position and the deployed position, the hinged coupling of the end cap to the ramp portion moves along an arcuate path .
A counterbalance for a ramp assembly includes a chain assembly and a spring assembly. The spring assembly includes a spring and first and second spring fittings. The first spring fitting restrains a first end of the spring when the ramp portion is between a neutral position and the stowed position and moves the first end of the spring toward a second end of the spring when the ramp portion moves from the neutral position toward the deployed position. The second spring fitting is spaced from the first spring fitting and restrains the second end of the spring when the ramp portion is between the neutral position and the deployed position. The second spring fitting moves the second end of the spring toward the first end of the spring when the ramp portion moves from the neutral position toward the stowed position.
A61G 3/06 - Transfer using ramps, lifts or the like

A ramp assembly includes but is not limited to a frame, a ramp platform functionally associated with the frame, a stow/deploy mechanism for deploying and stowing the ramp platform, and a drive assembly operatively connected to the stow/deploy mechanism for conditionally actuating the stow/deploy mechanism, which in turn, articulates the ramp platform between the stowed and deployed positions.
A barrier assembly for a wheelchair lift assembly is provided. The wheelchair lift assembly includes a lift frame and a platform reciprocally coupled to the lift frame. The barrier assembly includes a frame having a first side rail and a second side rail. The frame is coupled to at least one of the lift frame or a structural frame. The barrier assembly also includes a barrier slidably disposed between the first and second side rails. A drive assembly is operably coupled to the barrier for selectively moving the barrier between at least a stowed position and a deployed position.
B66B 9/08 - Kinds or types of lifts in, or associated with, buildings or other structures inclined, e.g. serving blast furnaces associated with stairways, e.g. for transporting disabled persons
A wheelchair lift assembly is provided. The wheelchair lift assembly includes a frame, a platform, and a lift mechanism associated with the frame. The lift mechanism includes a stabilizing arm and at least one lift arm member having a first end connected to the platform. The first end of the lift arm member pivots and translates relative to the platform as the platform is reciprocated between raised and lowered positions. The wheelchair lift assembly also includes a drive assembly. The drive assembly selectively provides a driving force to the lift mechanism without directly providing the driving force to the stabilizing arm.

E06B 9/26 - Lamellar or like blinds, e.g. venetian blinds
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 (1.02) when a force applied to the component exceeds a predetermined limit.
