    Abstract: The invention consists of a lifting apparatus. It is designed to enable a user and their mobility assistance device, such as a wheelchair or power scooter, to enter or exit a facility, i.e. residential or commercial, that has at least one step at the en trance. While the invention is in the “lowered” position. the user can move their MAD atop the platform contained in the present invention. While atop the platform, the user can activate the controls and cause the platform to be moved into the “raised” position. The “raised” position moves the user and their MAD upwards and towards the top step of entrance of the facility. The user can then mobilize their MAD and egress off the platform into the facility. If the user desires to exit the facility, the user then reverses the process and enters onto the platform when it is in the “raised” position. The user, while atop the platform, then lowers the platform to its “lowered” position and is able to egress off of the platform.

  • Patent number: 7721850
    Abstract: A height control mechanism for a lift device includes an elongated rail and an actuator slidingly mounted thereto. The actuator is biased toward a first end of the rail, and a proximity sensor is mounted proximate the second end of the rail. A cable pulls the actuator toward the second end of the rail as the lift device is elevated. When the proximity sensor detects the presence of the actuator, a signal is generated to halt further elevation. The position of the proximity sensor along the rail can be adjusted to set the maximum height of the lift device. A second proximity sensor, responsive to the presence of the actuator, can also be secured to the rail to generate a signal indicating that the lift device has been elevated off of the ground by a short distance.

  • Patent number: 7618223
    Abstract: A personal transfer device for transferring a boater from a dock to a boat moored in a boat lift adjacent the dock, and back again. A cantilevered support is secured to an upper part of the boat lift frame, the support's free end extending out over the dock at a height that does not interfere with normal use of the dock. A hoist carriage, for example a monorail trolley hoist, is movably secured on the cantilever support, and is connected to a transport chair that can be located over the dock at a convenient height for a handicapped boater to seat and/or secure himself. A controller is accessible to the boater seated in the transport chair to raise himself off the dock to a height sufficient to clear any intervening boat lift structures or frame members, and to then transport himself horizontally along the support through the boat lift structure to the boat, where he then lowers himself onto the boat using the controller.

  • Patent number: 7600611
    Abstract: The invention provides a stairlift having a rail which terminates, at its lower end, on or closely adjacent the lower step of a staircase. This rail is combined with a carriage and footrest which allows the footrest to be positioned below the level of the first step. The arrangement obviates the need for a hinge in the rail.

  • Publication number: 20080308358
    Abstract: A wheel chair lift device includes a lift car selectively elevated above a base, along with protective skirting covering the region below the lift car. Exposed portions of the protective skirting subject to lateral inward deformation are provided with skirt deformation sensors for detecting abnormal inward deformation of such skirt portions. The skirt deformation sensors include a spring or other elongated deformable member that extends generally parallel and proximate to the portion of the skirt being sensed. A sensor detects that the elongated member has been laterally displaced from its usual longitudinal axis and generates an electrical signal. In response to such electrical signal, the lift device stops further movement of the lift car.
