摘要： 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.

摘要： 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.

摘要： 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 restraint slidably coupled to a driving element having a spring fitting. The drive element includes a first engagement surface for engaging a first bearing surface associated with the ramp portion and a second engagement surface for engaging a second bearing surface associated with the ramp portion. A compression spring is disposed between a portion of the restraint and the spring fitting so that 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.

摘要： 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.

摘要： A method is disclosed for deploying a ramp assembly. The ramp assembly includes a ramp portion rotatable between a stowed position and a deployed position. The ramp assembly further includes a panel rotatable about a first end, wherein the ramp portion supportingly engages a second end of the panel to elevate the second end of the panel as the ramp portion moves toward the deployed position. The method includes the step of rotating the ramp portion until the ramp portion contacts an alighting surface. The method further includes the step of rotating the ramp portion until one of a first condition and second condition occurs. The first condition is that the ramp portion has reached a maximum slope. The second condition is that the second end of the panel has reached a predetermined elevation.

摘要： An operable ramp is moveable between a stowed position, a neutral position, and a deployed position. The operable ramp includes a ramp panel rotatably coupled at a first end about a first axis and a support that is rotatable in a first direction and a second direction about a second axis. A cam follower is coupled to the support and supportingly engages a second end of the ramp panel. Rotation of the support moves the cam follower along an arcuate path. The weight of the ramp panel biases the support in the second direction when the operable ramp is between the stowed position and the neutral position. A drive assembly selectively rotates the support in the first and second direction, and a stop limits rotation of the support in the second direction when the operable ramp is in the stowed position.
