A staircase mobility system is disclosed. The system includes a docking assembly that is configured to dock or undock with a dockable seat assembly. The docking assembly includes support rods configured to engage or disengage with the dockable seat assembly when docked or undocked, respectively. Further, the docking assembly includes dock connecters are disposed along the support rods. The dock connecters are configured to communicatively connect or disconnect with the dockable seat assembly when docked or undocked, respectively. Further, the system includes a drive assembly coupled to the docking assembly. The drive assembly includes a motor that is configured to drive the docking assembly along a guide rail in a forward or reverse direction, and to operate the docking assembly to dock or undock with the dockable seat assembly.

Systems, apparatuses, and methods are described for a stairlift overspeed safety system are disclosed. The overspeed safety system may include a centripetal cam assembly, a trigger assembly, and a jammer assembly. The centripetal cam assembly may include a spring-loaded plate and a plurality of centripetal cams connected to the spring-loaded plate, configured to move to an extended position when the rail speed exceeds the speed threshold. The trigger assembly may include a trigger plate configured to be pushed by at least one of the centripetal cams when moved to the extended position. Pushing the trigger plate may cause a switch to open to shut off power to the motorized stairlift. The jammer assembly may include a jammer configured to wedge between teeth of a rack and pinion of the motorized stairlift to initiate a deceleration to stop movement of the motorized stairlift.

A compact screw drive stairlift has the drive screw retained in a cavity within the rail and engages drive transfer elements extending along an inner surface of the cavity. The combined configurations of the screw and the rail ensure that the stairlift carriage is retained on the rail.

A footrest safety pad arrangement is incorporated in a stairlift carriage in which movement of a safety pad relative to the carriage is sensed by an electromagnetic sensor and a control signal applied to the stairlift drive motor.

A friction drive stairlift has a single drive wheel mounted to rotate in a plane passing through the centreline of the stairlift rail. The rail is preferably formed from two parallel tubes and a facility to maintain the chair level as the stairlift passes through a transition bend is preferably mounted on the same axis as the friction drive wheel.

A foldable stairlift includes a rail, a carrier that drives along the rail and a chair supported by the carrier. The chair and carrier define a stairlift unit. The chair includes a base body coupled to the carrier, a foldable seat body coupled to the base body, a foldable leg body coupled to the seat body, a foldable footrest body coupled to the leg body, a back rest body coupled to the base body, and a foldable armrest body coupled to the backrest body. Each of the seat body, leg body, and footrest body have their own respective folding system that controls the folding and unfolding of their respective seat body, leg body, and footrest body. And each folding system is controlled by an assigned motor that operates according to a variable speed profile. A method of controlling the folding and unfolding action of the foldable stairlift includes operating the motors according to one or more speed profiles.

A personal stair lift device transports a handicapped or immobile individual of higher than average weight capacity up and down a stairway on a chair assembly supported on a dual rail mount assembly. The stair lift device is used on a stairway on a dual track system aligned on both sides of the stairwell, connected to dual metal pipes, and is further connected to a plurality of metal brackets, containing steel braided cables. Braided cables are connected to guide wheels that can lift heavier weight capacity individuals.

The invention provides a method and apparatus for continuously adjusting the speed of a stairlift in response to a number of operating parameters such as battery voltage and motor current draw. The method preferably further includes monitoring the speed of a reference point on a stairlift chair and comparing this with a maximum permissible speed.
