A tower elevating assembly generally includes a platform assembly configured to move between a first elevation position and a second elevation position, a tower having a track assembly, wherein the track assembly includes first and second track portions, each being a single continuous structure, and a carriage assembly for providing support to the platform and moving within the track. A kit for a tower elevating assembly includes a platform assembly, a tower having a track assembly, and a carriage assembly configured for coupling with the platform assembly and the tower.

The invention describes a footrest for a stairlift chair in which the safety mechanisms included in the footrest are enveloped in a flexible cover that allows the safety mechanisms to function in the intended manner yet prevents the intrusion of dirt and objects that might interfere with the operation of the safety mechanisms. Various further features are described to enhance the aesthetics of the chair.

A folding mechanism for a chair and, in particular, to a stairlift chair, has a seat base, backrest and armrests. The folding mechanism ensures that all parts of the chair remain in a swivel arc whether the chair is in an in-use configuration or folded configuration. Various additional features are described including armrests formed in part by flexible straps.

A stairlift chair has a hand control displaceable in a fore/aft direction. Other aspects include a hand control which is mounted at a point beneath the armrest and a fabric covering which is applied to the armrests and the backrest support.

The present invention refers to a stairlift (1) comprising a first armrest (10) and a second armrest (10), wherein each armrest (10) is adapted to comprise at least one module (11, 12), and wherein said at least one module (11, 12) is adapted to provide at least one user control function; characterized in that the at least one module (11, 12) is adapted to be interchangeable between the first and second armrests (10).

A stair lift eliminates a hindrance to the normal use of a staircase. The stair lift comprises two rails disposed along the staircase in parallel to the width of the staircase, a self-propelled gantry-shape carriage having a gantry-shaped structure, traveling on the rails with a restriction to prevent a derailment, and a lift step (1) disposed between left and right leg structures of the gantry-shape carriage and supported by a lifting mechanism provided in the leg structure. When the gantry-shape carriage stands by at a lower floor or a upper floor of the staircase, the lift step (1) lands on the floor adjacent to the staircase or a step of the staircase, and when the gantry-shape carriage travels on the rails, the lift step is held at a position preventing an interference with steps of the staircase. A user gets on the lift step (1) while standing.

An apartment staircase automatic lift, comprising a combined structure of a carrying guiding-rail, a transmission-set main-body and a driving module; wherein the transmission-set main-body is set with a carrying wheel-seat and a transmission-set carrying-shelf; wherein the transmission-set carrying-shelf is set with a foot-pedal; when a person stands on the foot-pedal, the driving module can be controlled to drive the transmission-set main-body and the foot-pedal to move back and forth along the carrying guiding-rail between the upper and lower ends of the carrying guiding-rail; thereby helping the person to go up and down the staircase. The overall structure has the advantages of low cost, easy installation and operation, and compact structure; which can improve the defects of the conventional staircase-lift seat including the large volume size, occupying large staircase space, and being inconvenient to be arranged in a general apartment staircase.
