Definitions

  • the invention relates to an apparatus for transporting a load from a first to a second level, in particular a stairlift, comprising a frame which is displaceable along a rail and on which a load carrier is mounted and which is provided with support and guide means engaging round at least a part of the rail and with drive means co-acting with a propelling part of the rail.
  • a stairlift is described in EP 125 882 , and is furthermore generally known, for instance from EP 0 560 433 , EP 0 738 232 or EP 1 119 513 .
  • stairlifts use is made of a frame from which is suspended a load carrier such as a chair.
  • the chair is pivotable here about a horizontal axis so as to be able to keep the seat part thereof horizontal under all circumstances.
  • the frame itself is suspended via support or guide rollers or wheels from a rail which follows the course of the staircase.
  • the guide rollers or wheels run along the upper and/or lower side of the rail.
  • the known stairlifts are provided with a drive, generally a motor which drives a toothed wheel which engages in a gear rack along the rail.
  • the known stairlifts have the drawback that, when the rail goes through a bend in the vertical and/or horizontal plane, the guide rollers or wheels and the toothed wheel of the drive will not follow the same path because they engage at different positions on the rail and the gear rack respectively. There is therefore the risk of the toothed wheel moving out of engagement with the gear rack, whereby without special measures driving becomes impossible.
  • the differences in the path followed by the separate parts of the stairlift moreover make a stable control of the position of the seat part of the chair using an electronic control practically impossible.
  • the invention therefore has for its object to provide a transporting apparatus of the above described type wherein these drawbacks do not occur, or at least do so to a lesser extent.
  • this is achieved in such an apparatus in that the drive means are arranged in the frame for movement relative to the support and guide means substantially transversely of the direction of displacement of the frame.
  • the drive means can remain in contact with the propelling part, for instance the gear rack of the rail, even in bends, while the support and guide means continue to follow the rail precisely. Differences in distance from the centre line of the rail can thus be compensated in inside and outside bends.
  • Such a movement can be obtained in simple manner when the drive means are connected to the support and guide means for pivoting on at least one axis running substantially in the direction of displacement of the frame.
  • the drive means can for instance be connected to the frame via a member pivotable on two sides or a linkage.
  • the drive means is connected to the support and guide means for sliding in at least one direction.
  • the drive means are in this case preferably slidable along at least two guides enclosing a mutual angle.
  • the transporting apparatus preferably has movable means arranged between the drive means and the frame for transmitting drive forces generated by co-action of the drive means with the propelling part of the rail.
  • the force-transmitting means comprise at least two co-acting pushing members freely movable transversely of the direction of displacement of the frame.
  • the force-transmitting means may comprise at least one elongate pulling and pushing element.
  • a compact drive is obtained when the drive means comprise at least one motor and an output shaft which is connected thereto and on which is arranged a rotatable drive member co-acting with the propelling part of the rail.
  • the drive member is a toothed wheel and the propelling part of the rail comprises a gear rack.
  • this latter is preferably arranged on the side of the rail remote from the frame, and the output shaft of the drive means extends beyond the rail transversely of the direction of displacement of the frame.
  • the drive means are preferably adapted for this purpose to absorb a moment directed round the direction of displacement of the frame, while the support and guide means are adapted to absorb moments directed transversely of the direction of displacement of the frame.
  • the transporting apparatus is preferably provided with at least one support wheel which is mounted on the output shaft of the drive means and which engages on a protruding part of the rail. This shaft is thus used for driving as well as for transmitting the moment.
  • the support and guide means preferably comprise at least two guide rollers arranged with interspacing in the direction of displacement of the frame and engaging on the rail.
  • the support and guide means advantageously further comprise a number of pairs of guide rollers arranged distributed in peripheral direction of the rail.
  • the guide rollers are here preferably mounted in at least one roller carrier tiltable transversely of the direction of displacement of the frame. Bends in the rail can thus be easily followed.
  • the roller carrier takes the form of a ring segment with at least partly spherical outer surface, it can be readily received in the frame with the desired mobility.
  • roller carrier comprises two forks together forming a cardan suspension.
  • a stable guiding of the vertical transporting apparatus along the rail is achieved when there are at least two roller carriers which are arranged with interspacing in the direction of displacement of the frame and between which the drive means are arranged.
  • the transporting apparatus is preferably provided with means for maintaining the load carrier in a determined position, which position-maintaining means comprise at least one adjusting motor connected to the load carrier, a system for controlling the adjusting motor and sensors connected for signal generation to the control system for sensing the position of the load carrier.
  • the position-maintaining means are preferably adapted to place the load carrier in a desired position prior to the transporting and to adjust the position thereof at a bend in the rail. Control is thus simplified, since no intervention will after all be necessary during transport along straight parts of the rail.
  • the sensors are advantageously adapted herein to sense the position of the support and guide means relative to the frame and/or to sense the position of the drive means relative to the support and guide means. In this manner movements in the stairlift itself can be used to determine the position of the load carrier, and the sensing is therefore wholly independent of the rail.
  • the sensors are preferably contactlessly operating sensors, such as for instance optical or electronic sensors. Wear of the sensors is hereby avoided and settings can be modified using software instead of manually.
  • the invention further relates to an installation for transporting a load from a first to second level, in particular a stairlift installation, comprising at least one rail with a propelling part enclosing an angle with the horizontal and a transporting apparatus as described above displaceable therealong.
  • the propelling part of the rail can advantageously comprise a gear rack which preferably has a substantially round cross-section.
  • An optimum engagement of the driving toothed wheel in the gear rack is hereby ensured under all conditions, irrespective of the position of the drive means relative to the rail.
  • a strong, rigid but nevertheless relatively light rail is obtained when this latter likewise has a substantially round cross-section. Furthermore, an optimal contact between the support and guide means and the rail is then also ensured in bends.
  • the rail is preferably provided with a protruding part running therealong for co-action with the support wheel.
  • An installation 1 for transporting a load from a first to a second level in the shown embodiment a stairlift installation, comprises a rail 3 which is placed along a staircase 2 and which encloses an angle ⁇ with the horizontal H, and an apparatus 4 movable along rail 3 for transporting the load between the different levels, here therefore a stairlift.
  • Rail 3, which in the shown embodiment has a round cross-section, is supported by a number of posts 5 which are arranged distributed along staircase 2 and which are fixed to a protruding part 6 extending along rail 3 ( fig. 2 ). The function of this protruding part 6 is elucidated hereinbelow.
  • Rail 3 is further provided with a propelling part 7, here in the form of a gear rack 8, which has a round cross-section.
  • Stairlift 4 comprises a frame 9 which is displaceable along rail 3 and on which a load carrier 10 is mounted, here in the form of a chair with a seat 11, back rest 12, armrests 13 and a footrest 14.
  • Chair 10 is connected to frame 9 for pivoting on a horizontal shaft 45 ( fig. 3 ), and arranged in frame 9 is a maintaining mechanism 70 to be elucidated further hereinbelow and consisting of, among other parts, of an adjusting motor 71 connected to shaft 45 so that the position of chair 10 can be kept constant at all times irrespective of the inclination of rail 3.
  • Frame 9 of stairlift 4 is further provided with support and guide means 15 which engage round a part of the periphery of rail 3.
  • the frame 9 is given a substantially L-shaped form with an upright back 38 and two feet 26 engaging under rail 3.
  • the support and guide means 15 are adapted to absorb moments directed transversely of the direction of displacement of stairlift 4.
  • the support and guide means 15 comprise a number of guide rollers 17 which are arranged with interspacing in the direction of displacement and which engage on rail 3.
  • Guide rollers 17 are each rotatable on a shaft 18 and received per pair in a recess in a roller carrier 20.
  • the outer recesses are covered with a closing plate 19.
  • roller carrier 20 takes the form of a ring segment open to one side and having a spherical outer surface 21. The open side serves to allow the ring segment to engage round the protruding part 6 of rail 3.
  • roller carrier 20 there are two roller carriers 20 present, in each of which three pairs of roller 17 are arranged with a mutual spacing of 120° in peripheral direction.
  • Each roller carrier 20 is mounted at two diametrically opposite points in bowl-shaped dishes 24 connected to frame 9 such that it is in principle movable in all directions. Dishes 24 are fixed with a number of screws 25 to the foot 26 protruding under rail 3 and to a part 27 of frame 9 engaging over rail 3.
  • An imaginary line connecting the roller carriers 20 encloses a small angle ⁇ with the vertical V.
  • roller carrier 20 In order to limit the mobility of roller carrier 20 to two mutually perpendicular directions transversely of the direction of displacement of the stairlift, thus a tilting movement transversely of rail 3, there are formed in the outer surface 21 thereof two grooves 22 which run practically in the direction of displacement and in which a pin 23 engages in each case. This pin 23 protrudes out the bowl-shaped dish 24 in the middle. Through sliding of pins 23 in grooves 22 a rotating movement of roller carrier 20 about a practically horizontal axis is thus allowed, while a rotation of roller carrier 20 on pins 23 is also possible. On the other hand, the pins 23 prevent a tilting movement on the longitudinal axis of rail 3. In this manner bends in staircase 2, and thus also in rail 3, which generally cause rotations in both the horizontal and vertical plane ( fig. 4 ), can be followed extremely well.
  • Stairlift 4 is also provided with drive means 16 which co-act with the propelling part 8 of rail 3.
  • These drive means 16 are accommodated in a sub-frame 28 which here has a reverse L-shape and which is formed between the feet 26 of frame 9.
  • a roller 29 is mounted in sub-frame 28 for rotation on a shaft 30, whereby sub-frame 28 supports on rail 3.
  • Drive means 16 comprise a motor 31 with an output shaft 32 on which a rotatable drive member 33 is arranged which engages on the propelling part 8 of rail 3.
  • two batteries 34 are arranged at the top of sub-frame 28 in the shown embodiment.
  • the propelling part 8 is a gear rack and drive member 33 is thus embodied as a toothed wheel. Since gear rack 8 is arranged on the side of the rail 3 remote from frame 9, an output shaft 32 driven by motor 31 extends transversely of the direction of displacement under rail 3.
  • the output shaft 32 even extends beyond gear rack 8 and toothed wheel 33 as far as the protruding part 6 of rail 3.
  • a support wheel 35 which engages on the protruding part or strip 6 of rail 3.
  • a further closing roller 36 is mounted rotatably on a shaft 37 opposite support wheel 35.
  • the reverse L-shaped sub-frame 28 with the closing roller 36 mounted therein and the protruding shaft 32 with support wheel 35 thus form a unit almost wholly enclosing rail 3.
  • the sub-frame 28 with drive means 16 therein is movable relative to frame 9 substantially transversely of the direction of displacement of stairlift 4, whereby differences in distance from the centre line of rail 3 can be compensated in inside and outside bends.
  • Sub-frame 28 is connected for this purpose to the back 38 of frame 9 via a member 39 which has a pivot shaft 40 respectively 41 on either side.
  • the pivot shafts 40, 41 are herein oriented substantially in the direction of displacement of stairlift 4. Making use of two parallel pivot shafts 40, 41 achieves that sub-frame 28 is movable transversely of rail 3 in two mutually perpendicular directions.
  • force-transmitting means 42 are arranged in the shown embodiment between the sub-frame 28 of drive means 16 and the frame 9. These force-transmitting means 42 must be movable to be able to follow the movements between sub-frame 28 and frame 9.
  • the force-transmitting means 42 comprise for this purpose two co-acting pushing members or slide bearings 43, 44, one on sub-frame 28 and one on frame 9, which are freely movable transversely of the direction of displacement of stairlift 4.
  • these pushing members 43, 44 slide along each other, roughly in the manner of buffer stops on mutually coupled railway carriages. The drive forces can thus be transmitted at all times from rail 3 to stairlift 4, irrespective of the relative position of sub-frame 28 and frame 9.
  • the sub-frame 128 in which drive means 116 are arranged is movable relative to frame 109 by means of two linkages 150 on either side thereof.
  • Each linkage 150 comprises a substantially vertically directed bar 139 which is pivotally connected at the top and bottom via shafts 140, 141 to in each case two pivoting bars 151, 152 directed toward and away from rail 103 and oriented obliquely upward.
  • the bars 151 directed toward rail 3 are herein pivotally connected at their other end to sub-frame 128 via a shaft 153, while the bars 152 directed away from rail 103 are connected to frame 109 via a pivot shaft 154. Achieved once again in this manner is that relative to frame 109 the sub-frame 128 is movable transversely of rail 3 in two mutually perpendicular directions.
  • force-transmitting means 142 in the form of two pull and push rods or Panhard rods 155, an end 156 of which is connected to sub-frame 128 via for instance a hinge 157, while the other end 158 can likewise be connected via a hinge 159 to a spacer bar 160 of frame 109.
  • the support and guide means 115 otherwise comprise two relatively large guide rollers 117 on either side of rail 103 which are mounted directly in frame 109.
  • stairlift 4, 104 comprises a position-maintaining means 70, 170 which consists of an adjusting motor 71, 171 which is connected drivingly to pivot shaft 45, 145 of chair 10.
  • the construction and operation of this mechanism 70 is elucidated on the basis of the first embodiment of stairlift 4 and with reference to fig. 6 and 7 .
  • the operation of adjusting motor 71 is controlled by an electronic control system 72 which receives signals from a number of, in the shown embodiment six, motion sensors 73L, 73R, 74L, 74R, 75R.
  • control system 72 receives a further signal 76 from a sensor which senses the position of chair 10 when stairlift 4 is at rest, thus at the beginning or end of rail 3.
  • Control system 72 can optionally further receive a number of secondary signals, such as a signal from an acceleration sensor or electronic spirit level 77 connected to chair 10, and a signal 78 from sensors which sense a great resistance, an indication that something or someone is impeding the operation of stairlift 4. Finally, a further signal 79 indicating the speed of adjusting motor 71 is fed back to the control system. All these signals are processed in control system 71 and on the basis thereof a control signal 80 is generated to adjusting motor 71. The rotation of this adjusting motor 71 is transmitted to shaft 45 by a transmission 72 which is preferably self-locking, such as for instance a worm wheel transmission.
  • a transmission 72 which is preferably self-locking, such as for instance a worm wheel transmission.
  • the motion sensors 73, 74, 75 are embodied as contactlessly operating sensors. It is possible here to envisage optical sensors, such as CCD elements, or electronic sensors such as inductive elements. In both cases sensors 73, 74, 75 co-act with target members 81, 82, 83 arranged opposite. In the case of optical sensors the target members can be sensed optically, for instance in the form of a pattern of marks, while use can be made in inductive sensors of target members in the form of metal plates.
  • the sensors 73, 74 are fixed to frame 9, while the associated target members 81, 82 are arranged on the outer surface of roller carrier 20. Sensor 75 is here also fixed to frame 9, while its associated target member 83 is arranged on sub-frame 28.
  • the drive means could therefore also be slidable, for instance along two guides enclosing a mutual angle.
  • the drive means could therefore also be slidable, for instance along two guides enclosing a mutual angle.
  • the guide rollers could also be mounted in the frame in a different way, for instance by means of a cardan suspension or a linkage, while the force-transmitting means could also take another form. It is possible here to envisage balls or flexible elements rotatable in all directions, such as pulling cables, springs and the like.
  • connection between the drive means and the support and guide means is rigid enough.
  • the form and location of the drive could of course also be varied, for instance by applying a straight gear rack or a worm wheel.
  • the support wheel have to be combined with the drive, but it could be mounted separately on the frame or sub-frame.
  • the position-maintaining mechanism could also be embodied differently. More or fewer sensors could be used, and the sensors used could also be of electromechanical nature, for instance in the form of encoders which convert a mechanical movement into an electric signal.
  • the position-maintaining mechanism as described here could also be applied in combination with another type of stairlift.
