Definitions

  • the invention relates to a stair lift with a load-bearing device designed as a platform or as a seat, which is displaceably mounted on lower and upper support bars arranged along the stairs and is equipped with a motor-driven transmission.
  • European patent specification 00 19 014 has already disclosed a stair lift for use as a handicapped elevator of the generic type which, in addition to an upper and a lower support bar for supporting a load suspension device, uses a guide bar on which two idler rollers in one by means of a spindle nut on a drive spindle attack the guided bearing block.
  • the elevator can be moved along the support bars by adjusting the height of the idlers using the spindle nut.
  • vertical rungs are provided at equal intervals between the support bars, to which a segment plate is fastened approximately in the middle between the support bars.
  • a vertical drive spindle with a worm is arranged on the elevator, which works together with horizontal ribs on the segment plates.
  • the ribs on the segment plates effectively represent an unwound worm wheel and, when the drive spindle rotates, cause the elevator to be adjusted in height and thus inevitably move along the support bars.
  • the object of the invention is therefore to develop a new drive system that has greater rigidity with less effort and enables space-saving installation in existing stairwells.
  • a particular advantage is that the desired speed of the elevator is only determined by the inclination of the support rods and that design interventions in the transmission and the speed of the drive motor are not necessary.
  • Another important factor is that the higher speed of the known stair lifts in the curve area can not only be avoided, but can also be greatly reduced in a desirable manner.
  • the stair lift (Fig. 1) consists essentially of an upper support bar 1, which can also serve as a handrail of a banister, a lower support bar 2, which is guided close above the stairs at the ends facing the stair eye, between the two support bars 1 and 2 arranged vertical rods 4, in the central region of the vertical rods 4 attached and inclined support rods 6 and a load suspension device 8 (elevator not shown) with a motor-driven gear and an upper and lower roller cage (10, 11), each with two pairs of guide rollers 12 for Guidance of the load suspension device on the support bars 1 and 2.
  • the support bars 1 and 2 have the same dimensions and are parallel, perpendicular Pipes arranged one above the other, the diameter of which is dimensioned according to the load-bearing capacity of the stair lift.
  • the vertical bars 4 fastened between the support bars 1 and 2 are arranged at regular intervals and are bent uniformly over the major part of their length towards the stair lift, thereby creating space for driving the load-carrying device.
  • the inclined support rods 6 normally extend in the area of the steps (not shown) between three vertical bars 4, as shown in the right part of FIG. 1.
  • the direction of inclination of the support rods 6 is chosen steeper, whereby the support rods extend, for example, only over a field between two vertical rods 4 or only over part of a field, as in the left part of the Fig. 1 is indicated.
  • additional support rods 14 to 16 are provided which run parallel to the support bars.
  • the gearbox accommodated in a gearbox housing 18 consists of two guide plates 19 and 20, for example 2 cm thick, in each of which an endless groove 22 (FIG. 3) in the form of a slender "0" with a depth of approximately 1.5 cm is incorporated.
  • the groove 22 is semicircular in the upper and lower area and is rectilinear on both sides.
  • the two guide plates 19 and 20 are formed uniformly and arranged in the gear housing 18 (Fig. 1) at a distance of, for example, 3 cm so that the grooves on the inside lie exactly opposite one another.
  • guide sleeves 24 rotatably mounted on bolts 23 are guided in a closed, endless sequence, the length of which is precisely adapted to the distance between the guide plates 19 and 20.
  • the diameter of the bolts 23 corresponds to the width of the grooves 22.
  • the endless sequence of the guide sleeves 24 mounted on the bolts 23 is driven via a gearwheel pair 34 which is mounted in the upper part of the gear housing 18 and is composed of the gearwheels 34a and 34b, the tooth design of which is adapted to the diameter of the bolts 23 (FIGS. 1 and 3).
  • the pair of gears 34 is fixedly connected to a drive shaft 35 of the reduction gear 36 mounted in the gear housing 18 or in the guide plates 19 and 20.
  • the reduction gear 36 is attached to the side of the gear housing 18 with a motor 38.
  • the gear housing 18 is screwed on its top and bottom with an angle bracket 40 and 41, respectively.
  • the upper angle bracket 40 and the lower angle bracket 41 each have a roller cage 10 and 11 at their free ends.
  • the upper roller cage 10 is pivotably mounted on a pivot axis 43 and the lower roller cage 11 is pivotably mounted on a pivot axis 44.
  • the guide rollers 12 and 13 With the guide rollers 12 and 13 rotatably mounted in these roller cages 10 and 11, the load-bearing device 8 can be moved up or down on the support bars 1 and 2. Due to the pivotable mounting of the roller cages 10 and 11, the roller guide can continuously adapt to a variable slope of the support bars 1 and 2.
  • In the roller cages 10 and 11 there are four guide rollers 12 and 13 respectively arranged that two guide rollers 12 and 13 are mounted opposite each other on both sides of the support bars.
  • the inclined support rods 6 are arranged so as to overlap one another in such a way that in each area between the vertical rods there are two inclined support rods 6 one above the other. In this way it is ensured that when the load-bearing device 8 runs along the path formed by the support bars 1 and 2, at least two support rollers 26 are always in operative connection with the inclined support rods 6.
