Abstract

See full text

The convertible stairs for wheelchair accessibility combine a tiltable staircase with a vertically movable platform. The tiltable staircase includes rotating stairs which can be angularly adjusted between a stepped configuration and a planar, ramp-like configuration. Proximal ends of first and second staircase frames are pivotally secured to the platform such that selective raising and lowering of the platform causes the tiltable staircase to tilt up and down. When the stairs of the staircase are rotated into the planar, ramp-like configuration, the platform may be fully raised to tilt the staircase upward, creating a horizontal surface for the wheelchair to cross from the platform to an upper floor or level. To exit the upper floor or level, the wheelchair user reverses the process, returning to the platform which is lowered to the lower floor or level, also lowering the staircase. The stairs may then be rotated back to a stepped configuration.
