Definitions

  • the invention relates to a device for locking individual telescopic sections of an inclined lift, preferably a furniture lift, to one another, the guide rails of the telescopic sections being guided into one another having an upper single flange and a lower double flange, this double flange having a lower and an upper flange and the locking elements by means of the upper one At the end of the respective telescopic section arranged pivotable body guided ropes are brought into the operative position.
  • the German patent 30 01 410 is a goods lift has become known, which consists of a plurality of telescopic sections that are guided with their associated guide rails to each other or into each other. During the extension movement, ie during telescoping, all telescopic sections (possibly down to the last one) travel the same distances in the same times, ie they are together in a simultaneous relative movement to one another. When a sufficient extension length is reached, the telescopic sections are locked against each other.
  • Inclined lifts which are used in particular as furniture lifts, must, however, be able to be driven relatively precisely in order to be able to spend the platform of the furniture platform that can be moved on the guide rails of the inclined elevator as precisely as possible up to the height of a window opening.
  • the known locking mechanism is not sufficient for this.
  • the locking device consists of an eccentric that is constantly pressed against the extending guide rail during the extension movement of the telescopic sections by means of a low spring force, the eccentric bearing being made such that after the extension movement of the eccentric is completed, a swivel movement is carried out is pressed under the telescopic rail due to the sliding back of the telescopic rail and thus prevents the telescopic rail from further sliding back.
  • all telescopic rails In order for the locking to take effect, all telescopic rails must slide back a little. This does not allow the individual telescopic sections to be extended precisely.
  • Another disadvantage of the known solution is that the release of the lock can not be done regardless of the position of the load handler; rather, all of the interlocks that are effective between the individual telescopic sections must be run over for the purpose of detaching them from the load suspension device.
  • the known solution is extremely complex to construct.
  • a locking element which is displaceable in the longitudinal direction of the guide rail is provided and which "dives” in the course of its displacement process through a passage opening in the upper flange of the double flange. and presses frictionally and non-positively against the lower flange of the next (smaller) guide rail profile.
  • the locking elements are actuated using the rope technology essentially known from German patent specification 30 01 410, which are designed according to claim 2 as wedges, which have a toothing on their top with which they are supported on the underside of the next smaller guide rail.
  • the wedge forming the locking element slides on a non-displaceably connected mating wedge to the lower flange of the double flange and clasps the mating wedge with lateral guide surfaces.
  • the required thrust movement is forced on the wedge according to claim 5 by means of a sliding push rod.
  • the push rod (claim 6) is etched away from the end of the guide rail by means of a return spring, i.e. when the telescopic rope is actuated in the sense of "extending the rails", the wedge automatically releases from its clamping position and remains in the position ineffective for locking as a result of the return spring.
  • Claims 7 and 8 characterize details of the arrangement for the locking ropes.
  • the invention achieves a possibility for the stepless locking of the guide rails of the telescopic sections guided against one another; on the other hand, this stepless locking can be released again by simply actuating the telescopic rope (extending rails).
  • the inclined elevator 5 has a plurality of telescopic sections 1-4 and is supported in the area of the floor by a chassis 6.
  • a furniture platform 7 can be moved so far that the platform floor is as precisely as possible at the lower limit of a window opening 9 of a building 8.
  • the guide rails 10 are extended by actuating so-called telescopic ropes 33 (see FIGS. 9 and 10); After reaching the extended position shown in FIG. 1, actuating cables 34 and 35 are tensioned in a manner known per se via levers 36 and 37, (see FIG. 11) using the actuating cable 34 for direct locking between the telescopic sections 4 and 3 and by means of the actuating cable 35, pivotable bodies 13 are moved, which in turn tension additional cable sections 38 due to the pivoting movement, which in turn cause downstream pivoting bodies 13 to pivot and thus bring the locking into the operative position.
  • the guide rails 10 have an upper single flange and a lower double flange, which consists of the lower flange 12 and the upper flange 12 ', between which a web 39 is switched on.
  • a locking element 14 acting wedge 20 slidably mounted in the direction of arrow 16.
  • the wedge 20 has a toothing 19 on its surface and is made of a harder material - for example steel - than the guide rails.
  • a passage opening 17 is provided in the upper flange 12 '. The movement in the direction of the arrow 16 is forced on the wedge 20 by a push rod 26 which is connected to the wedge 20 in a joint 40.
  • a counter wedge 21 is fastened by means of a screw connection 22, which is supported in addition to the screw connection 22 with a support lug 23 on the upper flange 12 'of the double flange.
  • the wedge 20 slides on the counter wedge 21 and in the process encompasses it laterally with guide flanges 24. From FIG. 7 it can be seen that during the movement in the direction of the arrow 16 the wedge 20 passes through the passage opening 17 and with its toothing opposes it the bottom 18 of the next following smaller guide rail 10.
  • the push rod is supported on the end boundary 27 of the guide rails 10. This support takes place via a return spring 28, so that the wedge 20 is held in the unlocked position as a result of the return spring 28 as soon as the frictional connection is released by actuating the telescopic ropes 33 in the sense of "extending the guide rails".
  • actuating cable 35 has tensioned the cable sections 38 so that the pivotable body 13 in the image plane to the left in Arrow direction 41 swings out and automatically tensions the next cable section 38.
  • the compensating element 32, on which the locking cables 30 and 30 'associated springs 42 are articulated are also moved in the image plane to the left, so that the locking cables 30 and 30' connected to the stop 29 are obtained and the locking takes effect.
  • the locking is released - as mentioned above - by simply extending the guide rails by means of the telescopic ropes 33.
