Wheelchair lift with slidable support arm
View Patent ↗A wheelchair lift for use in conjunction with a vehicle having a floor. The lift includes a power actuating system, a platform assembly having first and second platform sections, and a linking assembly connecting the power actuating system to the platform assembly. The linking assembly includes first and second vertical arms connected to the platform assembly. The platform assembly is movable between a fully extended configuration, a pre-stowed position and a stowed position. The first and second vertical arms are a first distance apart when the platform assembly is in the fully extended configuration and the pre-stowed position and a second distance apart when the platform assembly is in the stowed position. The second distance is less than the first distance.
1. A wheelchair lift for use in conjunction with a vehicle having a floor, the lift comprising:
a power actuating system,
a platform assembly having first and second platform sections joined by a hinge,
wherein the platform assembly is movable between a fully extended configuration, a pre-stowed position, and a stowed position,
a linking assembly connecting the power actuating system to the platform assembly, the linking assembly having first and second vertical arms connected to the first and second platform sections, respectively, each vertical arm spaced from the other and from the hinge therebetween in the fully extended and pre-stowed positions, said vertical arms arranged for raising the platform assembly between the fully extended configuration and the pre-stowed position,
wherein, when the platform assembly is in the extended position the arms are spaced apart with the platform assembly therebetween and after the lift has been raised to the pre-stowed position, at least one of the vertical arms is movable toward the other vertical arm to the stowed position.
2. The wheelchair lift of claim 1 wherein the second vertical arm is movable toward the first vertical arm along a horizontal path.
3. The wheelchair lift of claim 1 , wherein the first and second platform sections are co-planar and lie in a substantially horizontal position when the platform assembly is in the fully extended configuration, and wherein the first and second platform sections are substantially parallel and lie in a substantially vertical position when the platform assembly is in the stowed position.
4. The wheelchair lift of claim 3 wherein the first and second platform sections are adjacent to one another when the platform assembly is in the stowed position.
5. The wheelchair lift of claim 4 wherein the second vertical arm is movable toward the first vertical arm along a horizontal path.
6. The wheelchair lift of claim 3 wherein the first and second platform sections lie in a substantially vertical position and are co-planar when in the pre-stowed position.
