Definitions

  • the invention relates to an elevator device with a drivable load-carrying device designed along a staircase platform or seat.
  • Such elevator or lift devices are used for example as disabled lifts and can be retrofitted in stairwells.
  • Disabled lifts are known, in which chains, racks or ropes with support members are used as the support and traction means.
  • the guide rails along which the seat of such an elevator rolls are installed in a box or channel, which must be permanently installed in the stairwell.
  • Such a box takes up part of the width of the stairs and may block the passage to landing doors on landing.
  • such an elevator must have a safety device or a special brake. This can result in a double number of cables or chains.
  • the known elevators also have the disadvantage of a very complex construction technology.
  • the invention has for its object to provide a simply constructed elevator device which meets the safety requirements and which does not reduce any significant space requirement only for the load-carrying device and, moreover, the free stair width and the platform room.
  • a drive spindle which can be moved up and down on the load-bearing device and which can be displaced up and down, and which is fixedly arranged along the stairs, the threads (thread turns) of which are in the thread (thread turns) of a bearing mounted on the support bars and which determine the guide path of the load-bearing device Border the guide device.
  • this guide device consists of a spindle nut which is mounted on the load suspension device and comprises the drive spindle and an additional guide bar arranged along the stairs and guiding the spindle nut is formed, which is arranged inclined with respect to the support bars.
  • the drive spindle is preferably equipped with a worm, the thread (threads) of which are in engagement with the thread (threads) of an associated worm wheel, the thread of which is unwound and arranged on a plurality of the same, fixed along the stairs and parallel to the support bars Segment plates is divided as a guide device.
  • Such an embodiment is particularly for long stairs Suitable, as any number of segment plates can be arranged at suitable intervals to the side of the stairs. Continuous pipes or the like running along the stairs as separate guide rails can be omitted. The support bars can replace the banister.
  • the pitch angle of the threads of the drive spindle as well as the angled threads (partial thread) of the worm wheel as a guide device can be varied.
  • a low overall height of the elevator device can be maintained.
  • the drive spindle can also be slidably arranged in a horizontal position.
  • An elevator device is installed in a staircase along a straight staircase 10 or along a helically curved staircase 11.
  • the elevator unit is supported in each case on an upper support bar 12 or 13 and a lower support bar 14 or 15.
  • a guide bar 16 runs between the upper support bar 12 or 13 and the lower support bar 14 or 15 according to FIG. 1 of the drawing and a guide bar 17 according to FIG. 2 of the drawing. All bars 12, 14 and 16 or 13, 15 and 17 are arranged vertically one above the other and held by a lower support 18 or 19 on the lower landing and by an upper support 20 or 21 on the upper landing. These supports run vertically from floor to ceiling on one floor.
  • the guide bar 16 or 17 determines the position of the elevator unit along the stairs. It runs in each case at the lower end of the stairs lo or 11 from the beginning of the lower support bar 14 or 15 to the end of the upper support bar 12 or 13 at the upper end of the stairs.
  • the support bars 12 and 15 and the guide bars 16 and 17 can be made of tubes.
  • the elevator unit contains a horizontal platform 22 with a vertical wall 23 on which a bracket 24 is attached is arranged.
  • An approximately C-shaped guide profile 25 is fastened to the rear of the wall 23 with the aid of screw bolts 26.
  • the guide profile 25 is arranged vertically, there is a lower bracket 27 at its lower end and an upper bracket 28 is attached to its upper end.
  • These cantilevers run parallel to the support bars 12 to 15 and are provided at their free ends with support rollers, by means of which the elevator unit is supported on the support bars 12 and 14 or 13 and 15.
  • a lower support roller 29 and an upper support roller 3 0 opposite this in relation to the lower support bar 14 or 15.
  • a lower support roller 31 and an upper support roller 32 are arranged at the free end of the upper arm 28, which bear against the upper support beam 12 or 13 on two opposite sides.
  • the upper support roller 3o is mounted with its horizontal pivot axis in each case in a pivot bearing with a vertical axis on the associated boom, while the lower support roller 29 is mounted on a pivot lever which can be rotated about the pivot axis of the support roller; 5 of the drawing, the upper support roller 3o is located with its pivot axis 33 on a bearing body 34 which is articulated on the boom 27 via a pivot bearing 35 with a vertical axis.
  • the pivot lever 36 is rotatably supported about the pivot axis 33, and the lower support roller 29 is rotatably supported at its free end.
  • the elevator unit thus hangs on its support rollers 29 to 32 on the support bars 12 and 14 or 13 and 15, along which it can travel.
  • the drive of the elevator device is located on the mobile elevator unit and is in engagement with the guide bar 16 or 17. It consists of a drive motor 37 arranged at the upper end of the guide profile 25, a downstream gear 38 and a vertical drive spindle 39 which is arranged within the guide profile 25 and is supported there with its ends. It is connected to the guide bar 16 and 17 via a support frame 40, a lower support roller 41 and an upper support roller 42.
  • a spindle nut 43 is screwed onto the drive spindle 39 as a guide device for the platform 22 and carries a bearing block 44 surrounding the drive spindle 39.
  • the axis 45 of the lower support roller 41 and a pivot lever 46 is inserted, at the free end of the upper support roller 42 is mounted with a horizontal axis 47.
  • the 'lower support roller 41 and the upper support roller 42 lie outside the guide profile 25 on two opposite sides of the guide bar 16 and 17 on this.
  • the bearing block 44 is located within the support frame 4o, on which it is supported at its upper end and at its lower end, so that it has to move with it.
  • the support frame 4o is displaceable in the vertical direction within the guide profile 25.
  • it has sliding shoes 48 on two vertical outer sides, which are fastened to the supporting frame 4o with the aid of screw bolts 49.
  • the bearing block 44 surrounding the drive spindle 39 is held in the radial direction on its underside by the spindle nut 43 and on its top by a second spindle nut 50. It has vertical bores which rest with their inner circular cylindrical surface on the outer surfaces of the spindle nut 43 and the second spindle nut 50. However, the bearing block 44 maintains a small distance from the second spindle nut 5o in the vertical direction.
  • the elevator device according to the invention works as follows:
  • the platform 22 is located on the lower landing.
  • the drive motor 37 is switched on and gives the drive spindle 39 a rotation about its axis via the gear 38.
  • the spindle nut 43 is held on the support frame 4o in the circumferential direction, so that it is not can rotate about its axis.
  • the spindle nut 43 must therefore move upward. It takes the bearing block 44 and the support frame 4o, which move upwards within the guide profile 25. Since the bearing block 44 and with it the support frame 4o is also held by the guide bar 16 or 17 via the support rollers 41 and 42, the upward movement within the guide profile 25 can only take place if the guide bar 16 or 17 permits this movement.
  • the inclination of the upper support beam 12 and the lower support beam 14 is at the beginning and changeable at the end of the carriageway, with the support spars initially going from bottom to top in a transition area from the horizontal to a constantly inclined direction, which they adhere to along the stairs and then at the upper end in a transition area from the inclined to the horizontal direction pass over. Since the inclination of the guide bar 16 is essentially constant, the support bars 12 and 14, which end at a different angle, result in a delayed travel speed of the elevator unit to the stops.
  • the use of the C-shaped guide profile provides further options for the way the lift is operated. If e.g. 1 is pivoted so that the spars 12 and 14 are vertical so that the lift can travel in the vertical direction.
  • the C-shaped guide profile 25 and the drive spindle 39 keep their angular position to the support bars 12 and 14, while the platform 22 is arranged relative to the guide profile 25 so that it is horizontal again. In a corresponding manner, a horizontal direction of movement of the elevator unit can be provided.
  • an elevator device is suspended from a guide which can simultaneously serve as a banister.
  • This guide consists of a lower guide bar 52 (support bar) which extends along the stairs 10 and a for this purpose, parallel upper guide bar 53 (support bar).
  • These guide or support bars are supported and fastened to vertical supports 54 above the stairs 10 and on one side of these stairs. Between two successive supports 54, a plurality of vertical rungs 55 are attached to the guide rails 52 and 53 at equal intervals.
  • the load receiving means of the elevator device on which a seat 56 is laterally fastened in the region of the stairs 1 is 0, so on the two guide rails 52 and 53 are suspended so that it can travel along it.
  • the guide rails 52 and 53 are formed from tubes with a circular cross section, so that 65, 66 can roll on their support rollers.
  • the load suspension device is designed as a frame with two vertical side struts 57, a lower cross strut 58, an upper cross strut 59, a lower connecting strut 6o and an upper connecting strut 61.
  • the suspension of the frame on the guide bars 52 and 53 is carried out via the connecting struts 60 and 61, and these each carry a plurality of idlers which can roll on the guide bars.
  • a vertical roller support plate 63 is pivotably mounted on each connecting strut 6o and 61 in a bearing 62 fixed there with a horizontal axis.
  • Two lower support rollers 65 and an upper support roller 66 are rotatably mounted on fixed bearing journals 64 protruding horizontally from this roller support plate 63.
  • the upper one is supported Carrier roller 66 above its guide rail 52 or 53 on this, while the two lower support rollers 65 are supported one behind the other in the direction of travel of the elevator device below their guide rail 52 or 53.
  • the load-bearing device of the elevator device can adjust itself to slight deviations from their parallelism while traveling along the guide rails 52 and 53, because the support rollers 65 and 66 are each pivotably mounted on a pivotable roller support plate 63.
  • a motor 68 with a belt drive 69 is arranged in a motor housing 67 above the frame for driving the elevator device. This drives a vertical drive spindle 7o, which is rotatably mounted in a lower spindle bearing 71 fastened to the lower cross strut 59 and in a spindle bearing 72 fastened to the upper cross strut 59.
  • a worm gear or the like is used to transmit the drive torque. Therefore, a worm 73 is arranged on the drive spindle 7o.
  • the toothing (the threads) of the worm 73 does not engage in a conventional worm wheel, but the counter toothing is unwound and thus the threads are divided into several segment plates 74 as a guide device, with each support 54 and rung 55 approximately in the middle between a segment plate 74, for example with screws 75, is fastened to the two guide rails 52 and 53.
  • the elevator device hangs on the guide bars 52 and 53 (support bars). Since the worm 73 is in engagement with the toothing (thread turns) of at least one segment plate 74 as a guiding device, the load-bearing device is held via the worm drive. Depending on the situation with a worm drive, there is self-locking. It is therefore not possible for the load-bearing device to set the worm 73 in rotation due to its weight. However, as soon as the drive spindle 7o and with it the worm 73 are set in rotation, its engagement with the toothings (of the thread turns) of the segment plates 74 causes the Load carrying device forced to move along the guide rails 52 and 53 via their support rollers 65 and 66.
  • the operating mode of the motor 68 can control the person to be seated on the seat 56 and supported on the footrest 76 on a control panel 77.
  • the seat 56 can be dismantled in a simple manner and the footrest 76 and the control panel 77 can be easily folded up if the full width of the stairs is exceptionally required for the entire length for other transports.
  • the drive spindle 7o is arranged vertically with the worm 73.
  • the drive spindle is in any other direction, such as inclined or horizontal.
  • the guide rails 52 and 53 as Support bars can be arranged in any direction, for example also inclined vertically or horizontally.
  • the elevator device according to the invention can also be designed as a tractor which pulls a plurality of load-bearing devices, such as platforms or seats, arranged one behind the other along the guide rails 52 and 53, so that several people and / or objects can be transported simultaneously.
  • load-bearing devices such as platforms or seats
