Definitions

  • the invention relates to an actuating and locking mechanism for weather protection hoods of a chairlift cable car that can be coupled to a chairlift cable car with a pivotable articulated on the chair between a first and a second chair-fixed stop from a closed position to an open position pivotable weather protection hood, which by means of control rails or the like when bypassing the station track a cable or the like. Can be actuated and locks the swivel between the weather protection hood and the armchair in the closed position.
  • Detachable armchairs from recirculating chairlifts are increasingly being equipped with weather protection hoods that can be swiveled upwards to compensate for the load.
  • the weather protection hoods According to international regulations, for safety reasons the weather protection hoods must be closed and locked while driving when there is no passenger in the armchair.
  • the weather protection hoods are actuated by control cables in the station track when bypassing the holding stations; i.e. At the entrance to the station, all closed hoods are unlocked and opened first. Passengers boarding are sensed with light barriers to close and lock the open hood of unoccupied chairs before leaving the station. For the rest, it is up to the passengers traveling with them to leave the weather protection hood open after the station exit or to close it by hand and open it again before the next station entry;
  • the closed weather protection cover of the armchair occupied may of course not be locked.
  • a two-stroke is pivotally articulated at one end on the weather protection hood and at the other end on the armchair, that the cable acts on one of the two levers of the two-stroke, and that the two-stroke with manual actuation of the weather protection hood in the closed position has a pre-deadlock position on assumes the associated first stop and when the weather protection hood is actuated with the cable in the closed position, it is pulled against a third stop through its dead center position or is pushed away from it.
  • a two-stroke arrangement is arranged between the armchair and the weather protection hood which can be pivoted between two fixed stops, which can be pressed against the third stop by the cable pull due to its dead center position.
  • the hood actuation and locking mechanism according to the invention thus consists of a four-bar linkage with four low-friction pivots, which is kept movable between the three stops.
  • the weather protection hood is firmly attached to the one swing arm of the four-bar linkage.
  • the length of the two levers of the two-stroke mechanism is such that the two-stroke mechanism assumes a pre-dead position on the associated armchair-fixed stop when the weather protection hood is manually operated in the closed position.
  • the weather protection hood Since the weather protection hood is firmly connected to the swing arm of the four-bar linkage, it cannot push the two-stroke through its dead center position.
  • the cable engages directly on one of the two levers of the two-stroke arranged between the weather protection hood and the armchair, i.e. either on the coupling or on the other swing arm of the four-bar linkage, and is able to force the two-stroke against the third armchair with little effort due to its dead center position Pull stop to lock the hood.
  • a wind force acting on the weather protection hood can therefore no longer open it because it presses the two-stroke further against the third stop and it is not possible to break through the dead center position of the four-bar linkage when force is exerted by the weather protection hood.
  • the first two fixed stops are preferably elastically deformable as a rubber buffer. So the first stop can give a little when the two-stroke goes through the dead center position; in the locked over-center position, the two-stroke is biased against the third stop.
  • the third stop is preferably fixed to the chair, ie a lever-fixed stop part strikes an associated chair-fixed stop part; alternatively, a limit stop between the two movable levers for the over-center position is also possible.
  • the cable pull preferably engages the lever of the two-stroke mechanism near the hood, with a favorable lever action, expediently with an attack lever oriented approximately perpendicular to the dead center position.
  • an unlocking lever is provided in the invention, which is firmly connected to the lever of the double stroke, on which the cable pull also engages.
  • this unlocking lever which can only be reached from the outside, the weather protection hood can also be unlocked outside the holding stations, for example in an emergency, regardless of the cable pull.
  • the transmission angle on the extended levers is then 180 °.
  • a chair, designated overall by 1, of a chairlift cable car essentially consists of a hanging frame; such armchairs can, depending on their width, usually accommodate up to six people.
  • a weather protection hood 2 is pivoted upwards in a swivel joint designated 1-2.
  • a bracket 9 with armrests and footrests is also pivoted upwards on the hanging frame.
  • Weather protection hood 2 and bracket 9 are mounted with their balancing points balanced by means of spring balancers, so they can be comfortably handled by the passengers in the armchair.
  • the armchairs coupled to a conveyor cable by means of cable clamps are uncoupled from the conveyor cable at coupling points in the cable car's stopping stations and then recoupled while they are holding the station on a track track cf. Drive slowly around to get on and off passengers.
  • the chairs 1 In order to protect the chair 1, which is mostly passenger-free during the descent, from weather influences during the ski run, the chairs 1 have an automatic hood-bracket actuation with locking in the closed position for the onward journey, which at the stops of the station track at the entrance and Exit attached control rails 10 can be actuated via a cable 3. Passengers boarding or alighting can be sensed, for example, with light barriers in order to close and lock the weather protection hood 2 on vacant armchairs 1 before the station exit or to open the armchairs 1 entering the station with the weather protection hood 2 closed for passengers ready to board, the control rails 10 are driven and brought into their functional position.
  • the hood is usually operated via the roller lever-operated cable 3.
  • the actuating and locking mechanism for the weather protection hood 2 is identified as detail X in FIG. 1 and is first explained in more detail below with reference to FIG. 2 with the aid of schematic sketches in its kinematic mode of action: (In this respect, reference is made to, among other things, the definitions of the construction guidelines VDI 2127 " Fundamentals of transmission technology - Definitions of the transmissions” and VDI 2145 " Level four-layer transmissions with rotary and thrust joints - Explanations of the concept and systematics)
  • the hanging frame of the chair 1 is to be seen as a frame-fixed reference system.
  • the hood swivel is again identified with its pivot point 1-2; there the weather protection hood 2 is articulated as a rocker arm.
  • a two-stroke mechanism 4.5 is arranged, which consists of two levers 4 and 5 articulated to one another at the pivot point 4-5, one end at the pivot point 1-5 on the frame 1 and the other end at the pivot point 2-4 is articulated on the rocker 2.
  • Frame 1, swing arm 2 and the two levers 4 and 5 thus form an inevitable mechanism, which is a quadrangle 1-2-4-5 with four pivot joints 1-2, 2-4, 4-5 and 1-5.
  • One lever 4 of the two-stroke 4.5 is guided as a coupling of the quadrangle 1-2-4-5, the other lever 5 is a second rocker.
  • the cable of the cable pull acts on the coupling 4 at the pivot point 3-4; the force acting thereby on the coupling 4 is shown schematically by the arrow S.
  • the weather protection hood can also be opened or closed by hand; the torque thus introduced on the swing hinge 1-2 into the quadrilateral 1-2-4-5 is shown schematically with the arrow H arrow.
  • Fig. 2-III shows the end position of the quadrilateral 1-2-4-5 on the associated chair-fixed stop when the weather protection hood is closed by hand:
  • the two-stroke 4.5 is dimensioned so that it is in this position just before its dead center position T, which is the extended position between the two levers 4 and 5.
  • the rocker 2 is therefore just before its reversal position; consequently, a torque introduced at the swing joint 1-2 is no longer able to push the two-stroke 4.5 through its dead center position T, because the transmission angle at the pivot point 4-5 between the two levers 4 and 5 is almost 180 ° in this end position and no torque can be transmitted via the swivel joint 2-4 between rocker arm 2 and coupling 4.
  • the locked weather protection cover can only be unlocked with the cable;
  • the unlocked weather protection hood can be opened both by hand and with the cable.
  • the end position of the quadrilateral 1-2-3-4 that results when opening the associated (not shown) armchair-fixed stop is shown in Fig. 2-V.
  • the rope force S introduced in the coupling point 3-4 or the torque H introduced in the swing joint 1-2 reverse their direction of action during the closing or opening movement.
  • FIG. 3 to 5 show a preferred constructive embodiment of the hood actuation and locking mechanism according to detail X in FIG. 1 in its three stop-limited end positions corresponding to the schematic sketches III to V of FIG. 2 with the associated three chair-fixed stops:
  • the lower rear corner of the weather protection hood 2 is accommodated in the swivel joint 1-2 fixed to the chair.
  • the hood 2 is pivotable between two chair-fixed rubber buffers 6 1 and 7 1 from its closed position according to FIGS. 3 or 4, in which the hood-fixed stop part 6 2 rests against the chair-fixed stop part 6 1 , into its open position according to FIG. 5, in which the hood-fixed stop part 7 2 rests against the chair-fixed stop part 7 1 .
  • FIG. 3 shows the pre-dead center position of the two-stroke 4, 5 with the weather protection hood 2 closed by hand.
  • FIG. 4 shows the locked over-dead center position, which can only be assumed when the cable 3 is actuated.
  • the cable of the cable pull 3 engages the lever 4 with a favorable lever transmission, that is to say with a lever 2-4 - 3-4 oriented approximately perpendicular to the dead center position T at the pivot point 3-4.
  • the third stop 8 consists of a lever-fixed stop part 8 4 , which strikes the chair-fixed stop part 8 1 ; the first stop 6 remains in engagement and secures the locked position on the third stop 8 with a certain elastic deformation.
  • the lever 2-4 - 3-4 for the cable 3 acting on the lever 4 at the fulcrum 3-4 is further extended and passes into an unlocking lever 4 'with which the weather protection hood 2 can be unlocked independently of the cable 3;
  • the mechanism 1-2-4-5 can also be unlocked by hand if the chair is outside the stop stations on the conveyor line.
  • This unlocking lever 4 ' can only be reached from the outside and can push the two-stroke 4, 5 in the same way as the cable 3 through its dead center position, because it is firmly connected to the same lever 4.
