Abstract: An overspeed governor for a stairlift includes a governor frame mountable to a carriage of a stairlift. A wheel is engageable with a rail of the stairlift along which the carriage is moveable. Translation of the carriage along the rail is transformed into rotation of the wheel or vice versa. A safety braking device has a braking surface movable between a first position and a third position. In the first position the braking surface is not allowed to engage the rail. A braking member is coupled to the wheel such that when said wheel rotates at a speed at or above a predetermined threshold, the braking member is moved from the first position to the third position. In the third position the braking surface engages said rail with a braking force to stop movement of the carriage along the rail. A soft landing means gradually slows movement of the carriage.

Abstract: A knockdown, portable lift is relatively compact and lightweight for transport and use where there is no existing means for lifting a load between a lower surface and an upper surface or where the existing means cannot be used. Components of the lift are stored in a base portion of the lift and are assembled on site for forming a lift frame extending between the upper and lower surfaces. A platform and drive assembly are supported on the lift frame and are driven together up and down tracks on each side of the lift frame using a rotary drive, such as a hand crank or electric motor, to power the drive assembly. The drive assembly is operable by a person on or off the platform from either the upper or lower surface or traversing stairs over which the platform is moving. The drive assembly incorporates a unique overspeed braking system and a unique clutch arrangement.

Abstract: Systems and methods for lifting a wheelchair in non-residential indoor facilities. Guide rails extend from a wheeled-base and include a bearing and transmission system for raising and lowering a platform on which a wheelchair occupant travels. The bearing system is powered by a hydraulic cylinder with a cable or chain connected to the bearing system. The chain or cable traverses over idler pulleys at various positions about the guide rails and connects to the bearing system at one end and to one of the guide rails at another end. As the hydraulic cylinder is operated, the lifting cable translates the bearing system linearly through the guide rails, which in turn lifts the platform to a desired level. The platform may be adjusted to maintain a generally level orientation even as the guide rails are tilted to accommodate inclinations. Additional outriggers and/or supports may be provided to increase balance and stability of the lift.

Abstract: A stair lift for lifting and lowering at least one person on a rail on a stairway. There is a carriage mountable to the rail, the carriage having a track engaging drive, and a motor to power the drive, the powered drive causing the carriage to move along the rail. There is a central support post mounted on the carriage and an offset arm connected to the seat support post. The offset arm is mounted to the carriage in one of a left side or a right side position. A seat is mounted on the offset arm, and a notched plate secures the seat in position on the offset arm in either the left side or right side position and permits the seat to swivel between a sideways facing position and an upward facing position to facilitate the person getting into and out of the seat.

Abstract: The present invention discloses an electromechanical traversing step system for transporting elderly users 12, infirm and others between floors of a building. A single moveable step 14 ascends or descends on a set of tracks 16 secured to the wall of the stairway 18 or the staircase structure above the flight of stairs 20. Travel is initiated by the user 12 positioning themselves on the movable step 14, selecting the ascension 22 or descension 24 switch and then gripping the handrails. Motion of the step commences and continues when a pressure sensor 26 responds to a force on the step 14 and the omic resistance of the user 12 is detected by sensors 28 in each of the handrails. Ascending motion continues until the tread of the movable step 14 is flush with the upper floor 30. The movable step 14 automatically returns to the docked position 32 at the bottom 34 of the staircase 18 once the user 12 departs from the step to the upper floor 30.
