摘要： An operable ramp is moveable between a stowed position and a deployed position to provide a sloped transition surface between upper and lower surfaces of an architectural setting. The operable ramp includes a housing disposed on the lower surface of the architectural setting and having a selectively adjustable height. A first ramp panel has a support element extending from a first end. The operable ramp also includes a drive assembly located within the housing. The drive assembly includes an endless loop coupled to an end of the support element to move the operable ramp between the stowed position and the deployed position. The endless loop has a linear portion located between first and second arcuate portions. The endless loop raises the end of the support element to deploy first ramp panel. The distance between the first and second arcuate portions is selectively adjustable.

摘要： An operable ramp is moveable between a raised position, in which the ramp forms a pair of steps, and a lowered position, in which the operable ramp provides an inclined surface. The operable ramp includes a first panel rotatably coupled about a first axis that moves back and forth when the operable ramp moves between the lowered position and the raised position. A link is rotatably coupled to the first panel about a second axis and is itself rotatable about a fixed third axis. A second panel is rotatably coupled to the link between the second axis and the third axis, and a third panel is rotatably coupled to the second panel about a fourth axis. When the ramp moves between the raised and lowered positions, the fourth axis rotates about a fixed fifth axis. A linkage selectively rotates the first panel about the first axis.

摘要： A ramp assembly for providing a transition surface between a vehicle floor and an alighting surface is disclosed. The ramp assembly includes a ramp portion that is rotatable between a stowed position and a deployed position. A sensor senses an angle of the ramp portion relative to a horizontal plane and provides a sensor output that corresponds to the angle of the ramp portion relative to the horizontal plane. The ramp assembly further includes a controller that receives the sensor output and an alert device. The controller controls the alert device to provide an alert when the angle of the ramp portion relative to the horizontal plane reaches a predetermined value.

摘要： A ramp assembly includes a ramp portion coupled for rotational movement between a stowed position and a deployed position. A first panel is rotatably coupled to the ramp portion about a first axis so that movement of the ramp portion between the stowed position and the deployed position moves the axis along an arcuate path. The ramp assembly further includes a guide that maintains a fixed position relative to the stowed position of the ramp portion. A second panel is slidably associated with the guide and is rotatably coupled to the first panel about a second axis.

摘要： 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.
