Abstract
A ramp assembly for providing passenger access to a passenger vehicle. The ramp assembly includes a ramp having a first ramp plate, a second ramp plate rotatably coupled to the first ramp plate, and a ramp assist assembly. A ramp fold arm is coupled to the ramp assist assembly and to the first ramp plate, wherein the ramp assist assembly directs deployment and retraction of the ramp plate. The link system is connected to the ramp fold arm and to the second ramp plate, wherein the link system includes a slide mechanism coupled to an underside of the first ramp plate. The slide mechanism maintains tension for the link system when deploying and retracting the ramp from the vehicle.
Claims16
A ramp assembly being moveable between a retracted position and a deployed position, wherein in the deployed position the ramp assembly is configured to provide rolling access to a passenger vehicle, the ramp assembly comprising:
- a first ramp plate;
- a second ramp plate rotatably coupled to the first ramp plate;
- a ramp assist assembly;
- a ramp fold arm coupled to the ramp assist assembly and to the first ramp plate, wherein the ramp assist assembly is configured to assist in moving the ramp assembly from the deployed position to the retracted position;
- and
- a link system connected to the ramp fold arm and to the second ramp plate, wherein the link system includes a slide mechanism coupled to an underside of the first ramp plate, wherein the underside faces a ground when the ramp assembly is in the deployed position, and wherein the slide mechanism and ramp fold arm are collectively configured to slide relative to the first ramp plate as the first ramp plate is moved between the retracted position and the deployed position;
- wherein the slide mechanism includes a slide bar slidably connected to the underside of the first ramp plate;
- wherein the slide bar includes a generally planar portion connected to the underside of the first ramp plate, a first bend extending from the planar portion, and a second bend extending from the planar portion, wherein the first bend is coupled to the second ramp plate and the second bend is coupled to the ramp fold arm.
A passenger vehicle to transport a passenger confined to a wheelchair, the passenger vehicle comprising:
- an entry to enable the passenger confined to the wheelchair to exit and to enter an interior of the vehicle;
- and
- a ramp assembly located at the entry, the ramp assembly being moveable between a retracted position and a deployed position, wherein in the deployed position the ramp assembly is configured to provide rolling access to the entry, the ramp assembly including a first ramp plate, a second ramp plate rotatably coupled to the first ramp plate, a ramp assist assembly, a ramp fold arm assembly coupled to the ramp assist assembly and to the first ramp plate, wherein the ramp assist assembly is configured to assist in moving the ramp assembly from the deployed position to the retracted position, and a link system connected to the ramp fold arm assembly and to the second ramp plate, wherein the link system includes a slide mechanism coupled to an underside of the first ramp plate, wherein the underside faces a ground when the ramp assembly is in the deployed position, and wherein the slide mechanism and ramp fold arm are collectively configured to slide relative to the first ramp plate as the first ramp plate is moved between the retracted position and the deployed position when the ramp assembly is in the deployed position;
- wherein the slide mechanism includes a slide bar slidably connected to the underside of the first ramp plate;
- wherein the slide bar includes a generally planar portion slidably connected to the underside of the first ramp plate, a first bend extending from the planar portion, and a second bend extending from the planar portion, wherein the first bend is coupled to the second ramp plate and the second bend is coupled to the ramp fold arm.
