Definitions

  • the invention relates to a drive device for stair lifts with one on one first (lower) and a second (upper) guide rail movably mounted Load suspension device and drive means interacting with a drive rail.
  • a generic drive device is known from DE 42 11 870 C1, at the driving force via drive rollers on a drive beam of rectangular cross-section is transmitted. This drive is only non-positive. Around Here to achieve the required driving force at permissible contact pressures is four Drive rollers required. A problem arises in that the roles squeeze if the drive spar is curved.
  • the invention has for its object a generic drive device for stair lifts to improve that no excessive contact pressure of drive rollers occur on guide tubes that are also used as a handrail.
  • a drive device for stair lifts with one on a first (lower) and a second (upper) guide rail movably mounted load suspension device and interacting with a drive rail Drive means solved, which is characterized in that the drive rail has regularly spaced engagement openings, and that the drive means two gear-like, arranged opposite one another and the drive rail with a radial contact force between them Have drive pulleys with radially projecting drive projections, wherein the drive protrusions with the engaging holes and the drive surfaces interact with the running surfaces in a positive and non-positive drive connection.
  • the invention further relates to a stair lift with a drive device according to the invention.
  • Fig. 1 shows an elevator according to the invention at the foot of a staircase in a Travel position, wherein a load-bearing device shown as a substantially frame-shaped 1 with paired lower guide rollers 2 on one first, lower guide rail 3 and upper, paired guide rollers 4 is movably supported and guided on a second, upper guide rail 5.
  • the guide rails 3, 5 form together with vertical rods 6 a banister, both guide rails and the upper guide rail 5 serves as a handrail.
  • FIGS. 1 and 2 one is closed on the load suspension device 1 carrying load-bearing support frame 8 vertically displaceably mounted, the support frame 8 in the present case with vertical guide bars 9 and Trusses 10 is provided, on which a drive motor 11 and others to be explained Drive elements are held.
  • a perforated rod 13 made from a flat steel strip by punching holes is made, is in an area between the guide rails 3 and 5 to the vertical rods 6 attached and extends substantially at a constant distance or parallel to the guide rails 3, 5 while they are in the initial area of the elevator before the bottom step 15 of the stairs down towards the first guide rail 3 is guided and in its lower end region approximately or completely runs vertically.
  • a gear 40 is flanged to the drive motor 11 which a pair of gear-like drive disks 17, 18 are pivotally held, wherein the drive discs receive the perforated rod 13 between them.
  • the perforated rod 13 consists of a Flat iron (Fig. 5), which at regular intervals with essentially double cone and reinforcing profile 21 is provided, e.g. by welding.
  • the perforated bar 13 is then on each vertical rod 6 with appropriate fasteners 22 (e.g. adjustment clamp) height and incline adjustable.
  • the perforated rod 13 has on an upper and lower side, in each case adjacent on both sides to the engagement openings 20, opposite running surfaces 23, 24, with which the drive pulleys 17, 18 (additionally) cooperate in a frictional or non-positive manner.
  • the engagement openings 20 can also be cylindrical (punched or lasered), in which case the truncated cone shape only trained in operation after a running-in period.
  • the drive disks 17, 18 are on shafts 30, 31 wedged against rotation, on which coupling gearwheels 32, 33 also wedged against rotation are so that the drive pulleys at the same speed in the opposite direction are coupled to one another in terms of drive.
  • the shafts 30, 31 are mounted in a housing 35, the shaft 31 by means of a by plate springs 36 spring-loaded bearing sleeve 37 transversely to their axial direction (in the region of the end section carrying the drive pulley 18) slightly is movable so that an adjusting screw 38 acting on the plate springs 36 an effective setting of the radial contact pressure with which the drive surfaces 27, 28 pressed against the treads 23, 24 is possible.
  • the contact pressure can be so can be set that e.g. 30% or even 50% of the total driving force to be transmitted are transferred frictionally, while the rest of the part is positive transmitted by the interaction of the bolts 25 with the engagement openings 20 becomes.
  • the housing 35 is with the shaft 30 pivotally held on a gear 40, the drive of the drive pulleys 17, 18 via the drive motor 11, the transmission 40 and the coupling gears 32, 33.
  • the shaft 30 is thus relative to the transmission 40 in terms of its axial position stationary, while the housing 35 and the shaft 31 pivotal movement around the Execute the longitudinal axis of the shaft 30 and thus a predetermined course of the Perforated rod 13 can follow.
  • the elevator or the load suspension device is located at the lower end point of its movement 1 and the support frame 8 each in a lower end position, which in 2 and 3 is shown, in particular the support frame 8 together with the drive motor 11, gear 40 and drive pulleys 17, 18 along the load suspension device and move down along the vertical area of the perforated rod 13 are.
  • the support frame 8 In an area in front of the lowest step 15 one with the elevator Overcoming stairs is thus the support frame 8 in a position that a easy loading or rolling of a wheelchair or similar on a horizontal platform of the support frame.
  • the support frame 8 To start up the elevator along the stairs, the support frame 8 must first overcome vertical height difference, the height of a level or the lowest level 15 corresponds to the stairs, since it is otherwise not in one of the guide rails 3, 5 parallel direction can be moved. For this, in a first movement section the support frame 8 moves vertically upwards, for which purpose only the drive motor 11 must be moved, since the perforated rod 13 is guided vertically is. As soon as the drive disks 17, 18 deviate from the vertical direction, reach curved transition section of the perforated rod 13, the support frame 8 reached a sufficient height so that its lower front edge no longer can collide with a stair step, and the elevator or the load suspension device 1 receives a forward component in accordance with the perforated rod 13 Direction of the guide rails 3, 5. After passing through the transition section 1, wherein the drive pulleys 17 and 18 holding housing 35 automatically according to the local inclination or curvature the perforated rod 13 has pivoted.
  • the perforated rod 13 bend as a flat iron with simple means and can twist, due to the flexible attachment to the vertical bars 6 A readjustment or fine adjustment is still possible during assembly. Allow further the holes in the perforated rod allow the drive surfaces to roll off without any problems the drive pulleys and also the bolts, especially in curves and transition areas.
  • the support frame Before the first stage, the support frame can be raised by up to 400 mm, see above that the guide rails or the handrail relative to the support frame by a corresponding Be lowered.
  • a load suspension device 101 is on a second, upper guide rail 105 by means of guide rollers 104 movably supported and guided, the guide rollers 104 on one Cross strut 104a of the load suspension device 101 are attached.
  • Load suspension device 101 by means of drive disks 117, 118 on a perforated rod 113 guided and driven, the perforated rod and drive pulley arrangement corresponds to the previous embodiment.
  • the perforated disks 117 and 118 are on a further cross strut 117a of the load suspension device 101 rotatable and opposite the perforated rod 113 is preferably preloaded by means of spring force.
  • the load suspension device 101 a support frame 108, which can carry a load, is vertically displaceable stored.
  • a platform frame 108a is indicated, to which, for example, a floor holding a wheelchair can be attached can.
  • the support frame 108 (and thus also the load suspension device 101) is by means of a along a cross strut 102a of the support frame mounted guide roller 102 a first, lower guide rail 103, the vertical position of the Support frame 108 relative to the load suspension device 101 from the respective local vertical distance between the guide rails 103 and 105 results as from 6 and 7 can be seen.
  • the upper guide rail 105 is a handrail of a staircase, it follows that a wheelchair standing on the support frame 108 in the area of the platform frame 108a or similar first raised from the lowered position shown in FIG. 6 before there is a substantial (forward) movement in the longitudinal direction of the stairs, so that the initial described in connection with the first embodiment Overcoming a bottom step of a stair section in this way is easy is possible.
  • a drive motor 111 is attached to an upper cross strut 111a of the support frame 108 and acts via a drive sprocket 150 and an endless chain 152 on a sprocket 154 fixedly connected to the drive pulley 117. Then to the drive sprocket 150 and the sprocket 154 is the drive chain 152 guided over a first deflection wheel 156, which on the upper cross strut 104a of the load suspension device 101 is rotatably mounted, and via a second deflection wheel 158, which is rotatably mounted on the lower cross strut 102a of the support frame 108.
  • a resulting lifting force acting on the support frame 108 results from that via the deflection wheel 158, which is connected to the support frame 108 via the strut 102a is two upward, approximately equal chain tensile forces act, while only one downward chain tensile force acts, namely that of Chain section that runs between drive sprocket 150 and sprocket 154.
  • the Lifting force thus corresponds to the chain tensile force in a first approximation.
  • drive pulleys 217, 218 with drive projections 225 and substantially frustoconical Grooves 226 in cooperation with a corresponding grooved rod 213 are used.
  • Such drive pulleys can be manufactured more cost-effectively as drive pulleys with bolts.
  • a grooved rod can also be used can be produced more cheaply, for example by whirling or hitting as with threaded spindles or screws.
  • the drive rod 213 can also have a helical groove be provided, resulting in a screw shape.
