Definitions

  • the invention relates to an elevator, in particular inclined elevator, with a first and a second fixed roadway profile, in particular roadway tube, in which guide rollers run on both roadway profiles, which are rotatably mounted on roller carriers and rest on the roadway profiles from different sides, at least one guide roller of the
  • the first roller carrier assigned to the first roadway profile is designed as a drive wheel, and the circumference of the drive wheel is pressed by spring force to the associated engagement area of the first roadway profile in such a way that the drive force of the drive wheel is transmitted at least essentially non-positively to the first roadway profile.
  • a known elevator of this type (GB-A-778 091) is designed as a chair system.
  • the entire driving force is transmitted non-positively to only one lane profile.
  • a second lane profile serves only as a guide profile on which guide rollers run, which are intended to keep the seat in a horizontal position at all times.
  • the known drive has not become established in practice. It can only be used for relatively low drive power.
  • the carriageway profiles serve exclusively as guide profiles on which associated guide rollers run.
  • the elevator is driven with additional drive elements.
  • a pull rope is provided which runs endlessly in the guide tubes and in which the connection between the pull rope and the load-carrying means takes place via a slot in the upper guide tube.
  • overhead conveyors are also already known, in which only a single carriageway tube is provided, on which a drive device runs, to which the load suspension device is attached with a bracket, as in a chair lift (EU 0 088 061 A2).
  • the drive force of the drive wheel is transmitted essentially non-positively to the roadway profile.
  • Such constructions developed from overhead conveyor conveyors have the serious disadvantage that they have no reliable guidance for the load suspension means. In most cases, they are therefore not permitted as passenger lifts, especially as handicapped lifts.
  • the invention has for its object to design an elevator of the type presupposed as known so that it can be manufactured inexpensively and still function perfectly with simple means and also permits high drive powers.
  • the elevator according to the invention has the advantage that the load suspension device is guided securely in any desired direction and change of direction.
  • the elevator according to the invention can run safely on both straight and curved lane profiles.
  • the roadway profiles can be arranged both horizontally and vertically, both ascending and descending.
  • the roadway profiles can also be curved in a top view and form tight curves, as is necessary, for example, for use in stairwells.
  • the construction according to the invention allows any desired travel path.
  • the driving force is generated by means of a guided compression spring.
  • a guided compression spring has the result that even in the event of a spring break, the remaining spring forces maintain a sufficient contact pressure of the drive wheels on the guide profiles.
  • the guided compression spring prefferably tensioned between the two roller supports pivotably mounted about horizontal axes and to engage at a distance from their pivot axes.
  • a staircase designated as 70 in total two parallel roadway profiles 1 and 2, which are designed as roadway tubes, are arranged on a side wall.
  • the roadway profiles 1 and 2, which run parallel to one another, have a constant pitch, ie a constant, perpendicularly measured distance from one another.
  • an upper drive which has a motor 3 and a transmission 4.
  • the transmission drives a drive wheel 7, which is rotatably mounted about an axis 14 on a roller carrier 5, which forms a pivotable area of a chassis 6.
  • the drive wheel 7 is coated with a plastic pad 7a made of polyurethane to increase the coefficient of friction.
  • the drive wheel 7 is firmly connected to a coaxial gear area 11.
  • the gearwheel region 11 is in engagement with a gearwheel region 12, which in turn is firmly connected to a counter wheel and is rotatable about an axis 15.
  • the drive wheel 7 and the mating wheel 8 clamply grip the roadway profile 1 provided between the two.
  • the roadway profile 1 has an engagement region 1a which is roughened. The circumference of the drive wheel 7 runs from this engagement region 1a.
  • Drive wheel 7 and engagement area 1a are thus in a frictional engagement with one another.
  • roller carrier 5 of the chassis 6 there are also two guide rollers 9 and 10 which are rotatably mounted thereon.
  • the distance between the axis of rotation 14 and the axis of rotation 15 can be changed in that the axis of rotation 15 is formed by an eccentrically mounted bolt, not shown.
  • a lever arm 16 is fixedly connected to the eccentric area of the bolt.
  • a spring element 17 engages. This attack takes place in such a way that the direction of attack tends to reduce the center distance between the axes of rotation 14 and 15. According to the spring force, the contact pressure between the drive wheel 7, the counter wheel 8 and the track tube 1 can be selected in this way.
  • a chain sprocket 18 is seated on the drive wheel 7, mounted coaxially with the latter.
  • a chain drive 13 runs over the chain sprocket 18 to the lower drive shown in FIG.
  • the lower drive corresponds in its basic structure to the upper drive with the proviso that the drive movement is not initiated via a motor and a transmission, but via a lower chain sprocket and the drive chain 13 into a lower drive wheel 27.
  • the drive wheel 27 is in positive engagement with the counter wheel 28 via corresponding gear areas.
  • Guide rollers 29 and 30 are seated on the pivotably mounted lower roller carrier 25.
  • the drive by means of a motor 3 takes place via a gear 4 to a double sprocket 35.
  • the driving force is transmitted to a further double sprocket 34 by means of the double chain 33.
  • the axis of rotation of the double chain wheel 34 is also the pivot axis for the roller carrier 5 ', which is pivotally attached to the chassis 6'.
  • a central sprocket 38 is driven via a sprocket 37 driven coaxially with the double sprocket 34, which in turn is in engagement with a gearwheel region mounted on the drive wheel 7 'and on the counter wheel 8' in a rotationally fixed manner.
  • a sprocket 39 and a chain 36 drive a sprocket 39, which transmits its rotational movement in an analogous manner to the drive wheel 27 ′ and the counter wheel 28 ′ on the lower pivotable roller carrier 25 ′, as does the sprocket 37 in the upper roller carrier 5 ′ does.
  • the upper roller carrier 5 ' has a lever arm 31.
  • the lower roller carrier 25' has a lever arm 32.
  • a variable-length lever 40 is arranged at the free ends of the two lever arms 31 and 32.

  • FIGS. 6 to 8 show a further embodiment as a so-called chair system.
  • the drive takes place via a motor 3 and a gear 4 drives a drive wheel 7 ′′, which is firmly connected to a gearwheel region 11 ′′.
  • the gear area 11 ′′ meshes with a gear area 12 ′′, which is fixedly connected to a counter gear 8 ′′.
  • the rotational movement of the drive wheel 7 ′′ is transmitted to a sprocket 42 and from there via a chain 43 to a lower sprocket 44.
  • This lower sprocket 44 is non-rotatably connected to the lower drive wheel 27 ′′, through the center of which the pivot axis for a lower roller carrier 45 is running.
  • the lower roller carrier 45 has a relatively small counter roller 28 ′′.
