Definitions

  • stair lifts in general comprise a rail, which forms the track along a stair, which rail may in numerous situations be curved.
  • the seat of the stair lift follows the curved rail, which may lead to some rocking or inclement of the seat during movement.
  • the seat may therewith incline too, which causes the risk of a person sliding off the seat.
  • a provision may be present for balancing the seat.
  • Such provision may be an automated balancing system, with electr(on)ic actuators.
  • actuators may unexpectedly refuse or fail, which leads to dangerous situations.
  • the risk of failing is quite high in systems comprising a worm drive for leveling the seat. After years of operation the worm drive may be worn out, so that the worm may suddenly disengage the gear of the worm drive.
  • GB 2 322 450 A describes an annular ring inclinometer which can be implemented for use in a stairlift, wherein for safety reasons, a safety circuit actuating a brake depending on a preset amount of inclination may be implemented.
  • GB 2 322 450 A discloses a stairlift according to the preamble of claim 1.
  • the object involves provision of a breaking mechanism allowing for advantageous interaction with a stairlift's worm drive.
  • the invention thereto proposes a stair lift, comprising at least one rail extending along a track, a frame, suspended on the at least one rail, and comprising a drive, for moving the frame along the rail, a support for a seat, movable, in particular pivotable with respect to the support, a balancing system, for keeping the seat in a predetermined orientation with respect to a fixed world and a lock for locking the movement of the seat with respect to the frame.
  • the locking system prevents the seat to get in undesired angles with respect to the frame, and thus indirectly with respect to the fixed world. It is to be understood that the lock may be a separate part of the stair lift, and not - for instance - just a software routine in the balancing system.
  • the lock is configured to lock the movement of the seat with respect to the frame when the seat is moved more than a predetermined angle.
  • the lock may comprise detection means for detecting that the predetermined angle was reached. In particular these may be mechanical detection means, such as a hole or protrusion.
  • the predetermined angle may be defined with respect to the frame, or with respect to the fixed world, and may for instance be 5 or in particular 10 degrees.
  • the lock comprises a brake, which is in particular a drum brake or a disk brake.
  • the lock may further be configured for disabling the balancing system when it is locked, or initiate an immediate correction of the balancing system when the predetermined angle was reached, in order to prevent a person positioned in the locked angle for a long time.
  • the lock may further be configured for disabling a drive, for moving the frame part along the rail when it is locked, so that no person is moved with the lift while sitting under an angle.
  • the balancing system comprises a worm drive, having a worm spindle and a worm gear engaging each other.
  • the worm spindle is mounted at the support and driven by a motor.
  • the worm gear is mounted to the seat.
  • Figure 1 shows a stair lift in a desired uninclined position.
  • the stair lift comprises a rail 1 extending along a track, a frame 2, suspended on the rail 1, and a drive (not visible), for moving the frame 2 along the rail; a support 7 for a seat 3, which is movable, in particular pivotable with respect to the frame 2.
  • the stair lift 1 comprises a balancing system 4, for keeping the seat in a predetermined uninclined orientation with respect to a fixed world, provided with a lock for locking the movement of the seat with respect to the frame 2. Embodiments of the lock are depicted in figures 3 to 4 .
  • Figure 2 shows a the stair lift from figure 1 in an undesired inclined position
  • Figure 3 shows a first embodiment of a brake for the stair lift from figures 1 and 2 , wherein the brake comprises a drum brake 5.
  • Figure 4 shows a second embodiment of a brake for the stair lift from figure 1 and 2 , wherein the brake comprises a disk brake 6.

Claims (5)

  1. Treppenlift, aufweisend:
    - mindestens eine sich entlang einer Bahn erstreckende Schiene (1);
    - einen Rahmen (2), der an der mindestens einen Schiene aufgehängt ist, und aufweist:
    - einen Antrieb zum Bewegen des Rahmens entlang der Schiene;
    - einen Träger (7) für einen Sitz (3), drehbar montiert auf dem Rahmen;
    - einen Sitz (3), der in Bezug auf den Rahmen (2) beweglich, insbesondere schwenkbar ist;
    - ein Ausgleichssystem, das dazu geeignet ist, den Sitz (3) in einer vorgegebenen Ausrichtung in Bezug auf eine feste Umgebung zu halten,
    wobei
    - das Ausgleichssystem mit einer Blockiervorrichtung (5, 6) ausgebildet ist zum Blockieren der Bewegung des Sitzes (3) in Bezug auf den Rahmen (2); und
    wobei die Blockiervorrichtung eine Bremse aufweist,
    dadurch gekennzeichnet, dass
    die Bremse eine Trommelbremse (5) oder eine Scheibenbremse (6) ist; und
    dadurch, dass
    die Blockiervorrichtung dafür konfiguriert ist, den Antrieb zu deaktivieren.
  2. Treppenlift nach Anspruch 1,
    wobei die Blockiervorrichtung (5, 6) dafür konfiguriert ist, die Bewegung des Sitzes (3) in Bezug auf den Rahmen (2) zu blockieren, wenn der Sitz um mehr als einen vorgegebenen Winkel bewegt wird.
  3. Treppenlift nach Anspruch 2,
    wobei der vorgegebene Winkel in Bezug auf den Rahmen definiert ist, oder wobei der vorgegebene Winkel in Bezug auf die feste Umgebung definiert ist, oder wobei der vorgegebene Winkel 5 Grad, insbesondere 10 Grad, beträgt.
  4. Treppenlift nach einem der vorhergehenden Ansprüche, wobei die Blockiervorrichtung dafür konfiguriert ist, das Ausgleichssystem zu deaktivieren, wenn sie blockiert ist.
  5. Treppenlift nach Anspruch 2,
    wobei die Blockiervorrichtung mechanische Detektionsmittel aufweist, um zu erfassen, dass ein vorgegebener Winkel/der vorgegebene Winkel erreicht wurde.
