Definitions

  • the invention relates to an armchair for a chairlift cable car with a weather protection hood and with an actuating and locking mechanism for this weather protection hood, which are pivoted to the armchair and between a first one and a second stop from a closed position on the stop is pivotable into an open position at the stop, wherein the actuation and locking mechanism when driving around the Station tracks of control rails can be operated using a cable and the pivot between the weather protection hood and the Armchair locked in the closed position at the stop.
  • the task is therefore to be solved, one with the lowest possible actuation force controllable, i.e. So low-friction locking with such a hood actuation and locking mechanism to create.
  • the Hood actuation and locking mechanism thus consists of a quadrilateral joint with four low-friction swivel joints, which is between the three Stops is kept limited mobility.
  • the weather protection cover is firmly attached one wing of the four-bar linkage.
  • the two levers of the two stroke are in hers
  • the length is dimensioned so that the two-stroke in manual operation of the weather protection hood in in the closed position, a pre-dead center position on the associated armchair-fixed stop occupies.
  • the weather protection hood Because 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.
  • a wind force acting on the weather protection hood can therefore they no longer open because they continue the two stroke against the third stop presses and penetration of the dead center position of the four-bar linkage when force is applied is not possible from the weather protection hood.
  • the first two chair-fixed stops are preferably elastically deformable as Rubber buffer executed. So the first stop can give a little when the Two stroke goes through the dead center position; in the locked overdead position Biased against the third attack.
  • the third stop is preferred armchair-fixed, i.e. a lever-fixed stop part strikes an associated chair-fixed part Stop part on; alternatively there is a limit stop between the two movable levers for the over-center position in question.
  • the cable pull preferably engages the lever near the hood with favorable leverage of the two-stroke, expediently with an approximately perpendicular to the dead center position aligned attack lever.
  • an unlocking lever is provided in the invention, which with the lever of Two strikes is firmly connected, on which the cable pull also attacks.
  • the weather protection hood can be, for example, in one Unlock the emergency outside of the holding stations regardless of the cable.
  • the transmission angle on the extended levers is then 180 °.
  • the same effect is also given in the top position of the two levers, in which the transmission angle is 0 °; also in this pre-deadlock position stands as Wing of the four-bar linkage on the armchair hinged weather protection hood shortly before hers Reversal of movement and cannot push the two-stroke through its dead center position.
  • FIG. 1 there is a chair, designated overall by 1, of a chairlift cable car essentially from a hanging frame; such armchairs can, depending on their width, usually accommodate up to six people.
  • a weather protection hood 2 On the hanging frame is behind the seat a weather protection hood 2 in a swivel designated 1-2 pivoted upwards.
  • a bracket 9 is also on the hanging frame Armrests and footrests can also be pivoted upwards.
  • Weather protection hood 2 and bracket 9 are in terms of their pivot points by means of spring balancers weight-balanced stored, so can be from those in the armchair Handle passengers comfortably.
  • the on a conveyor rope using rope clamps Coupled chairs are attached to the dome stations in the cable car stops from Conveyor rope uncoupled and then coupled again, while holding the stop on one Track track cf. Drive slowly around to get on and off passengers.
  • armchair 1 has an automatic one Hood-bracket actuation with locking in the closed position for onward travel, those attached to the stops of the station track at the entrance and exit Control rails 10 can be actuated via a cable 3.
  • Getting on or off Passengers can be sensed, for example, with light barriers to 1 on unoccupied armchairs close and lock the weather protection hood 2 before leaving the station or at the entrance to the station with the weather protection hood 2 closed
  • the control rails 10 controlled and brought into their functional position.
  • the hood is actuated usually via the cable lever 3.
  • the actuation 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 terms and systematics)
  • the suspension frame of the Armchair 1 can be seen as a frame-fixed reference system.
  • the hood swivel is back designated with its pivot point 1-2; there the weather protection cover 2 is fixed to the frame as Swing arm articulated.
  • Two stroke 4.5 arranged, the two at the pivot point 4-5 articulated with each other connected levers 4 and 5, one end at the pivot point 1-5 on frame 1 and is articulated at the pivot point 2-4 on the rocker arm 2.
  • Frame 1, swing arm 2 and the two levers 4 and 5 thus form an inevitable mechanism, the one Quadrilateral joint 1-2-4-5 with four swivel joints 1-2, 2-4, 4-5 and 1-5.
  • One lever 4 of the two-stroke 4.5 is a coupling of the quadrilateral 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 hereby on the Coupling 4 acting force is shown schematically with the arrow S. That is further Weather protection hood can be opened or closed by hand; this on the swing arm Torque introduced in the quadrilateral 1-2-4-5 is with the Bow arrow H shown schematically.
  • the two-stroke 4.5 is dimensioned so that it is in this position shortly before it Dead center position T is located, which is the extended position between the two levers 4 and 5.
  • the Swing arm 2 is therefore just before its reversal position; hence one is on the swing arm pivot 1-2 initiated torque is no longer able to double stroke 4.5 by pressing its dead center position T, because the transmission angle at the pivot point 4-5 between the two levers 4 and 5 in this end position is almost 180 ° and over the swivel 2-4 between rocker 2 and coupling 4 no torque can be transmitted.
  • the cable pull that acts on the coupling 4 at the pivot point 3-4 with the cable force S transmits a torque corresponding to the lever 3-4 - 2-4 via the coupling-fixed swivel joint 2-4, whereby the two-stroke 4.5 due to its dead center position against another (not shown) frame-fixed stop is pressed into a locked position from which it can only be released with rope force S; because a (e.g. through on the weather protection hood wind forces) on the swing arm 1-2 in the quadrilateral 1-2-3-4 The torque introduced pushes the two-stroke 4.5 further against its armchair-fixed Attack.
  • the locked weather protection cover can only be unlocked with the cable; the The unlocked weather protection hood can be opened either by hand or with the cable possible.
  • The are fixed when opening the associated (not shown) chair
  • the end position of the quadrilateral joint 1-2-3-4 is shown in Fig. 2-V.
  • the Rope force S introduced in coupling point 3-4 or that introduced in swing arm pivot 1-2 Torque H each return during the closing or opening movement Direction of action around.
  • 3 to 5 is a preferred constructive embodiment of the hood actuation and locking mechanism according to detail X in Figure 1 in its three Limit-limited end positions according to the schematic sketches III to V the 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.
  • 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, with a certain elastic deformation, secures the locked position on the third stop 8.
  • the lever 2-4 - 3-4 is for the cable 3 which acts on the lever 4 at the pivot point 3-4 further extended and passes into a release lever 4 ', with which the Weather protection hood 2 can be unlocked independently of the cable 3; for example in an emergency the mechanism 1-2-4-5 can be unlocked by hand even when the armchair is is located outside of the stops on the conveyor line.
  • This release lever 4 ' is only accessible from the outside and can the two-stroke 4,5 in the same way as the Push cable 3 through its dead center position because it is fixed with the same lever 4 connected.
