Abstract: A stairlift for moving along a staircase having: a curved rail having a centre line, a load bearing surface, and a carriage including a first and a second guiding unit connected to each other by a connecting unit. The second guiding unit is connected to the connecting unit via a third rotation joint about a third axis and a fourth joint about a fourth axis, the connection unit includes a fifth rotation joint about a fifth axis. The fifth axis extending from outside the rail to an area close to or on the centre line of the rail in a first plane close to or on the third and the fourth axis.

Abstract: A stairlift with an elongated rail includes a first side running surface and a second side running surface; and a carriage movable along the rail. The carriage having a first roller including a first roller friction surface which is in frictional engagement with the first side running surface for guiding the first roller; and a second roller including a second roller friction surface which is in frictional engagement with the second side running surface for guiding the second roller; and a first bridge. The first roller being rotatable around a first axis at a first end of the first bridge and the second roller is being rotatable around a second axis at a second end of the first bridge.

Abstract: A stairlift for conveying a load along a staircase rail includes a rail, a carriage carried by the rail and moveable along the rail, a carriage drive to drive the carriage along the rail, a load carrier support supporting a load carrier, such as a chair or wheelchair platform, which load carrier support is rotatably connected to the carriage to rotate about a horizontal axis, a rotation device to rotate the load carrier support relative to the carriage about the horizontal axis, and a control unit to control the rotation device such that the load carrier support is positioned in a desired orientation relative to a horizontal plane. The rotation device includes a motor and a rotator, where the motor is operatively connected to the load carrier support via the rotator to cause rotation of the load carrier support relative to the carriage about the horizontal axis.

Abstract: A stair lift for transporting a load includes a longitudinal guide having a first side running surface and a second side running surface opposing the first side running surface; and a carriage which is transportable along the guide and provided with rollers for guiding the carriage along the guide. The rollers include a first roller having a first roller peripheral friction surface which is in frictional engagement with the first side running surface for guiding the carriage along the guide and a second roller having a second roller peripheral friction surface which is in frictional engagement with the second side running surface for guiding the carriage along the guide. The first roller friction surface is provided with a first roller member, and the first side running surface is provided with a longitudinal first side running surface member which fits complementary with the first roller member.

Abstract: Transport unit 1 for climbing or descending a slope or stairs along a rail provided with a strip, the transport unit comprises a main frame 3 and a guide mechanism 5. The guide mechanism 5 may have at least two guides 13 which guide the transport unit along the rail and a drive mechanism with a drive wheel for driving the transport unit along the rail by engaging the strip at an engagement point. The main frame 3 may be suspended from the guide mechanism 5 in a position around, substantially equal and/or lower than the engagement point.
