Document Type and Number:
Japanese Patent JP2003519554
Kind Code:
A
Abstract:
A wheelchair lift having a foldable platform including a first platform portion foldably coupled to a second platform portion, a lifting frame, at least one lifting arm with one end pivotally coupled to the lifting frame and the other end connected to the second platform portion and adapted to pivot the lifting arm between a substantially vertical stowed position and a substantially horizontal deployed position. A post extends from the lifting arm and a locking assembly is pivotably coupled to the lifting frame. The locking assembly includes a lever arm pivotably coupled to the lifting frame, a gas spring extending between the lever arm and the lifting frame which operates to resist pivoting of the lever arm, and a mechanical spring extending between the lever arm and the lifting frame which exerts a biasing force operating to pivot the lever arm to engage the post. Pivoting the lifting arm to the deployed position actuates unfolding the platform, while pivoting the lifting arm to the stowed position actuates folding the platform and engages the post with the lever arm.
