Definitions

  • This invention relates to a hand-operated releasing and displacing apparatus for a staircase lift or similar transport apparatus, comprising a carrier portion movable along a rail by means of a wheel driven by an electric motor and a reduction gearbox, and in which, a brake is actuated automatically in the event of motor standstill or power failure, said hand-operated releasing and displacing apparatus comprising a drive means in the form of a spindle rotatably mounted and slidable longitudinally against spring bias to a hand-operation position, and being adapted on the one hand to be coupled to the wheel drive mechanism and on the other hand to an actuation member, which drive member, upon longitudinal sliding movement to the operable hand-operation position, operates a current break contact and a mechanical brake releasing device.
  • the user can displace himself to a stopping-place by means of the hand-operated releasing and displacing apparatus.
  • the user of the apparatus known from GB-A-2 083 292 should depress the drive member via the actuation member against spring bias into the hand-operation position, after which the staircase lift can be displaced by turning the actuation member.
  • the user mostly an aged or partly disabled person, may have substantial problems in simultaneously keeping the actuation member in its depressed position and turning it.
  • both the retention of said spindle in the hand-operation position and of the brake releasing device in the releasing position can be realized in a simple, advantageous manner when in accordance with a preferred embodiment of the present invention, one end of the L-shaped lever is pivotally secured and is coupled to the brake and the other end is arranged in such a manner that it is displaceable by said radial projection for the release of the brake by pivoting movement of the lever during longitudinal sliding movement of the drive spindle, said radial projection being in the form of a conical face terminating in a receding slot capable of receiving the other end of said L-shaped lever to maintain the brake release.
  • the brake releasing apparatus is used for locking said drive spindle in the hand-operation position, while the retention of said spindle in that position at the same time maintains the brake release.
  • this combined operating position can be realized by merely displacing said spindle longitudinally by means of said actuation member. It is thus possible to realize the hand-operation position by depressing the actuation member, while subsequently said actuation member need only be turned to displace the staircase lift.
  • the motor spindle of the staircase lift will mostly extend vertically.
  • a convenient hand operation of the staircase lift preferably has an actuation member having a horizontal spindle.
  • the drive spindle carries a gear wheel which, upon longitudinal sliding movement of said drive spindle into the hand-operation position, proceeds to coact with a gear wheel coupled to the wheel drive, the shafts of the two gears being perpendicular to one another, said gear transmission thereby providing for an effective construction insensitive to play and wear.
  • the actuation member is mounted on the drive spindle in disengageable fashion, in which case the only visible feature of the hand-operation facility needs to be an encasing with an insertion opening for the actuation member.
  • the drive mechanism shown in Figs. 1 and 2 is provided with an electric motor 1 driving via a reduction gearbox 2 a spindle 3 whereon is mounted a wheel construction 4.
  • Wheel construction 4 runs along a rail, not shown, whereby a slip-free displacement is obtained by coaction of a gear 5 with a rack mounted on the rail.
  • the drive mechanism is secured through a base plate 6 on a frame, not shown, which may further include a carrier construction, such as a platform or a seat.
  • a carrier construction such as a platform or a seat.
  • brake 7 which becomes operative in the event of motor standstill or power failure.
  • brake 7 can be released mechanically by means of a lever 8. The operation of said lever will be further discussed hereinafter with reference to Fig. 3, and so will the operation of the releasing and displacing apparatus 9 mounted contiguous with brake 7 and operable by means of a turning wheel 10.
  • the apparatus 9 shown in Fig. 3 comprises a housing 11 accommodating a spindle 12 for turning and sliding movement.
  • a conical gear wheel 13 adapted to coact with a conical gear wheel 14 mounted on spindle 15 of electric motor 1.
  • Gear wheel 13 is urged out of engagement with gear wheel 14 by means of a spring 16, which position is indicated by a dashed line.
  • Spring 16 ensures at the same time that a portion 17 of a current break contact mounted on the left end of spindle 12 is kept out of coaction with the other portion 18 of said contact.
  • spindle 12 Adjacent the other end, spindle 12 is provided with a cross pin 19 adapted to coact with a transverse slot 20 in a bush 21 slidable on spindle 12.
  • Bush 21 is provided with a conical face 22 which, when bush 21 is pushed on spindle 12, comes into contact with the free end of the upright leg of the L-shaped lever 8, the end of the other leg being pivotally mounted in brake 7.
  • Conical face 22 terminates in a peripheral groove 23 adapted to receive the end of the upright leg of lever 8.
  • apparatus 9 The operation of apparatus 9 is as follows. When the lift has come to a standstill betweentwo stopping- places as a result of power failure or other disturbance it can be displaced manually by placing bush 21 on turning wheel 10 on spindle 12 until cross pin 19 abuts with the end of transverse slot 20. Further displacement results in sliding movement of spindle 12 in its bearing in housing 11. This has a triple effect. First, gear wheel 13 is brought into engagement with gear wheel 14. Second, the break contact is closed by contact of portions 17 and 18, so that any current supply to the entire driving mechanism is prevented. Third, due to the sliding movement of the free end of the upright leg, lever 8 is tilted, so that brake 7 is released. The ⁇ lift will then not be displaced automatically, as a result of a self-braking effect in the reduction gearbox 2.
  • spindle 12, bush 21 and turning wheel 10 may be integral or be mutually slidable otherwise. It is also possible to arrange spindle 12 parallel to and adjacent shaft 15, in which case straight gear wheels can be used and lever 8 is operated by moving spindle 12 vertically downwards, just as the current break contact. In that case, also bush 21 could be mounted in housing 11, within which spindle 12 telescopes and is securable in its active position by means of bayonet-like transverse slot 20. Besides, it may be preferable in practice to place the apparatus 9 in an entirely enveloping encasing containing only an opening for inserting bush 21. Another possibility is to fixedly connect the portion of bush 21 with the conical face 22 and the adjoining peripheral groove 23 to spindle 12, when an entirely enveloping encasing, if any, need only contain an opening for the passage of the spindle of turning wheel 10.
