Abstract: A retractable safety platform system for use between a train and a station platform, to thereby ensure a passenger will not fall or be pushed onto a path of the train, includes a rigid barricade platform adapted to be anchored to an outwardly facing side of the station platform registered along a vertical plane, and a mechanism for automatically reciprocating the barricade platform along a vertical linear travel path upon detecting first and second triggering events respectively. The linear travel path is defined along the vertical plane extending above and below a top surface of the station platform. In this manner, the barricade platform is displaced from a lowered retracted position to a raised extended position when the first triggering event is detected. The barricade platform is displaced from the raised extended position to the lowered retracted position when the second triggering event is detected.

Abstract: An operable ramp is moveable between a raised (step) position and a lowered (ramp) position. The operable ramp includes a first panel rotatably coupled about a first axis, the first axis that moves back and forth as the operable ramp reciprocates between the raised and lowered positions. A second panel is rotatably coupled to the first panel and extends downward from the first panel in the raised position. The second panel also rotates about a fixed second axis. The first and second panels cooperate to provide an inclined surface when the operable ramp is in the lowered position. A linkage selectively rotates the first panel about the first axis. The operable ramp further includes a third panel rotatable about a fixed third axis. The third provides a surface between the first panel and a fixed panel when the operable ramp is in the raised position.

Abstract: 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.

Abstract: A pivotable fold-down step system mounted to a vehicle, such as a fire truck or rescue truck, and synchronized to extend and retract by vehicle door motion. The step system is designed to easily achieve ingress and egress requirements stated within the National Fire Protection Agency (NFPA) guidelines. The step remains sealed and contoured to the vehicle profile when in the upright stowed position when the vehicle door is closed. The fold down step is operated by means of a pressurized fluid system which is integral to the vehicle. As the vehicle door opens the step is extended downward, under pressurized control, to allow for rapid and safe egress from the vehicle. As the vehicle door closes, the step is again operated by the pressurized integral fluid system and the step rises and folds into a stowed position within the vehicle body prior to transport of the vehicle.

Abstract: A stair assembly for a passenger vehicle, especially an omnibus, in which the stair assembly is arranged in a lateral access area of the vehicle. The stair assembly comprises a horizontally extendable first stair member connected by links to a second stair member to form a parallelogram linkage in which the second stair member can be pivotally moved towards the ground and laterally outwards from the first stair member. In order to bridge a lateral gap between the vehicle and the edge of a boarding platform, the first stair member whose upper surface is at the level of the platform, is extended towards the edge of the platform and the second stair member is carried along in a parallel position beneath the first stair member. When the bus is to be boarded and unboarded from the ground, the first stair member is fully extended, together with the second stair member beneath it whereafter the second stair member is pivoted into lowered position.

Abstract: A movable step displaceable by means of an operating mechanism between a withdrawn position and a service position has an extension in the form of two transverse arms associated with two pairs of link-arms which are pivotally mounted on four shafts having horizontal and parallel axes. Two shafts are stationarily fixed on the floor of the railway car, the second shaft being set back from the first with respect to the car wall. The other two shafts are movable and attached respectively to the transverse arms near the point of connection of these arms to the step, and to the transverse arms at the ends which are pivotally attached to the rear link-arms. Stable immobilization of the step is achieved in the service position as a result of abutting application of the articulations of the transverse arms and of the rear link-arms against a stop.
