Definitions

  • the invention relates to a drive for a goods lift guided on at least one support bar, in particular for a stair lift for the disabled, which is in positive engagement with a motor-driven drive wheel with a drive bar attached to the support bar.
  • a drive of the generic type is already known, in which the drive bar attached to the support bar is designed as a rack.
  • a rack-and-pinion gear equipped with a pin engages in the toothed rack equipped with strongly rounded teeth arranged in the same pitch.
  • the pins of the rack wheel have a barrel-shaped shape, in order to ensure trouble-free running of the rack wheel on the rounded teeth of the rack, especially in curved path areas of the support spar.
  • the teeth of the rack have a small width, so that their engagement takes place only over the central region of the pins of the pinion wheels. In curved path areas, the teeth only have a point contact with the pins of the rack-and-pinion wheels, which has the disadvantage of rapid wear of the drive means.
  • DE-A-255 65 34 describes a stair lift with a running rail on which the rollers of a transport carriage are guided, which is supported on a transverse force support rail arranged at a distance below it.
  • the car is also driven by a rack-and-pinion wheel, which works together with a rack arranged on the underside of the running rail, which is bent in the form of a rack and pinion from a sheet of steel.
  • This rack and pinion version requires the use of a square tube for the running rail, since otherwise a careful fastening of the steel sheet strip to the running rail is not possible.
  • the use of the known drive with a square tube is therefore limited to straight-line support bars and is not suitable for curved path areas.
  • the drive bar 1 can be bent in the plane of its wide flat side in a wide range of the radius of curvature if cuts are made at right angles to the centers of the bores 6 in the flat iron on the edge opposite the outer edge 2, hereinafter referred to as the inner edge 8.
  • These incisions 10 are of course only made in the area that requires a bend in the drive bar in order to allow a perfect contact with the support tube 12. With a concave bend of the drive bar 1 according to FIG. 1b, the incisions 10 would widen towards the inner edge 8, as shown. It is therefore necessary that the incisions 10 in the areas of the drive bar 1, which require a convex curvature, as shown in Fig.1a, must be sufficiently V-shaped before the bend.
  • the attachment of the drive bar 1 to the support tube 12 after the bend is advantageously carried out by welding.
  • FIGS. 1a and 1b show an embodiment with the drive principle explained in connection with FIGS. 1a and 1b, which allows two different speeds for the movement of the load suspension device along the support tubes 12 and 13 of a stair lift, e.g. a faster speed along the straight path and a slower one around a curve of the path.
  • the design of the drive bar can be simplified and modified, as can be derived from the schematic side view of Figure 4.
  • Crucial for a trouble-free and smooth running of the drive described is the exact observance of the division A according to Fig.1a and 1b is required, to which the division of the roller bearing of the drive wheel 14 must be adjusted.
  • the drive strips 1 and 30 (Fig. 2 to Fig. 4) can be replaced by cuboid blocks 38 and 39, which must be aligned very precisely and must be arranged with constant division directly on the guide tube 12 or a support strip 31.
