Definitions

  • the present invention relates to an elevator installation, which comprises a plurality of stacked shaft doors with horizontally displaceable shaft door wings, and an elevator car with a car door, which has at least one horizontally displaceable car door leaf.
  • Stationarily arranged in the elevator shaft stop means cooperate with a mounted on the car door sash stop means to limit an opening movement of the car door sash with certain deviations of the stationary position of the elevator car from the target stop position.
  • the target stop position is to be understood below as the position of the elevator car in which the level of its cabin floor coincides exactly with the level of the floor in whose area the elevator car is currently located.
  • An elevator installation which comprises a safety device with the aforementioned features.
  • a coupling element protruding in the direction of the door-side wall of the elevator shaft is provided on the cabin door panel, which couples the cabin door panel with an opposing shaft door panel if the elevator cage is sufficiently accurate at a shaft door level or floor level.
  • a vertically oriented stop plate is attached to the door-side inner wall of the elevator shaft. This limits an opening movement of the shaft door fixed to the coupling element, and thus the shaft door itself, when the elevator car has stopped so far below the target stop position associated with a shaft door that the horizontal projections of the coupling element and the stop plate overlap one another.
  • Purpose of the safety device according to JP04080191A is to make the big and expensive safety aprons unnecessary, which are installed below the threshold of each shaft door. Such safety aprons prevent a passenger from falling into the space between the elevator car and the door-side shaft wall after having opened the car door of the car which is stationary below the desired stopping position.
  • the invention has for its object to provide an elevator system with a safety device of the type described above, which does not have the disadvantages mentioned.
  • an elevator system is to be created in which the safety of the passengers is ensured even if the elevator car has stopped too far above the desired stopping position.
  • a high safety apron mounted underneath the car door sill shall be dispensed with.
  • the proposed solution should be feasible with less material and installation effort, with different floor distances should not require different components of the safety device.
  • an elevator system which comprises an elevator shaft, a plurality of shaft doors arranged one above the other, each with at least one horizontally displaceable shaft door leaf and one Elevator cabin comprising a car door having at least one horizontally displaceable car door leaf, wherein a vertically extending barrier ruler is attached as a stop means and two vertically spaced, stationary stop cams are mounted on a height lying between the door leaves vertically adjacent each shaft doors, each one the stop cam limits the horizontal opening movement of the ratchet and thus of the car door leaf when the position of the elevator car deviates in a positive or negative vertical direction, ie in the upward direction or in the downward direction, by a defined minimum distance from the target stop position.
  • the stationary stop cams are fixed to stationary elements of the shaft doors, for example on the shaft door sills, on the door fenders or on covering elements. This ensures that the slings must not be attached during assembly to the shaft wall, the position of which can vary greatly with respect to the shaft doors and the car door. Elaborate drilling and alignment during assembly can be avoided.
  • the stop cams are placed so that a hoistway door, in front of which the elevator car assumes a position in which a stop cam prevents the full opening movement of the ruler and the car door leaf, can be fully opened by the maintenance staff, on the condition that the elevator car so far removed from the target stopping position is that the driver device between the car door leaf and shaft door leaves is no longer engaged.
  • the maintenance personnel for example, have access to the car door drive, to the car roof or to elevator components present under the elevator car, when the elevator car and the car door are blocked.
  • the above-mentioned entrainment device is to be understood as a coupling device by means of which, in the case of a floor stop of the elevator car, the shaft door leaf is unlocked from the cabin door leaf and opened or closed, but its function (engagement) only within a limited zone in the region of the desired stop position given is.
  • the height of the stationary stop cam is at most 50 mm. This minimizes alignment during assembly as well as material costs and transport weight.
  • the length of the barrier ruler can be determined very simply. This always corresponds to the height of the landing door wings, reduced by the sum of the upward and downward permissible deviations of the actual position of the elevator car from its desired stop position.
  • a designed according to this rule barrier ruler has the minimum length at which the intended functions of the safety device are still feasible.
  • the stationary stop cams are fixed so - for example, on stationary elements of the shaft door - that they are vertically displaceable under the action of a certain vertical force.
  • barrier ruler and / or the stop cam are already mounted on the cabin door leaf or on elements of the shaft doors upon delivery of the elevator system.
  • Fig. 1 shows schematically a vertical section through an elevator system according to the aforementioned prior art. Shown are a door-side shaft wall 102 of a hoistway 101 with three shaft doors 103.1-103.3 arranged one above the other and an elevator car 105 in two positions which deviate greatly from the setpoint stop position assigned to the middle hoistway door 103.2.
  • the elevator car 105 comprises a car door 106 with a car door leaf 107, to which an engagement element 108 is attached, which, when opening the door during normal operation, couples the car door leaf 107 with one of the shaft door leaves 109.1-109.3.
  • vertically aligned stop plates 110 are mounted so as to prevent or at least limit an opening movement of the engaging member 108 and thus of the car door leaf 107 when the elevator car 105 too far below a shaft door 103.1-103.3 associated target stop position is positioned, as is the case in the lower of the positions of the elevator car 105 shown in FIG. 1.
  • the purpose of the described device is to prevent a passenger from falling into the open space between the elevator car 105 and the door-side shaft wall 102 when the elevator car 105 is below a target stop position associated with a hoistway door and the passenger opens the car door.
  • the disclosed device can not prevent a passenger, for example, when attempting to leave the elevator car 105 standing relatively far above the target stopping position associated with the shaft door 103.2, rushes through the opened car door 106 and the opened shaft door 103.2 into the elevator shaft.
  • the arrow P assigned to the upper position of the elevator car 105 shown in FIG. 1 shows the possible path of such a fall. Although this risk of falling could be eliminated by a particularly high, attached below the car door sill 116 safety skirt 117, but this would be associated with the serious disadvantage that the shaft pit of the elevator shaft would be carried out correspondingly deep.
  • FIG. 2 schematically shows a vertical section through the door-side shaft wall 202 of an elevator system according to the invention with two elevator doors 203.1, 203.2 vertically adjacent and through an elevator car 205 shown in two different vertical positions.
  • the shaft doors 203.1, 203.2 each comprise at least one shaft door leaf 209.1, 209.2 a shaft door frame 213 comprising a shaft door sill 214 is guided horizontally displaceable.
  • the car door 206 includes at least one car door leaf 207, which is at a car door sill 216 comprehensive cabin door frame 215 is guided horizontally displaceable.
  • the car door leaf 207 is opened or closed by a door drive, not shown.
  • a driver device 208 likewise not shown in this view, is fixed, by means of which, in the case of a floor stop of the elevator car, the shaft door leaf is unlocked from the car door leaf and opened or closed.
  • the elevator car 205 is shown in the upper part of FIG. 2 in a stop position, which is below a target stop position associated with the upper shaft door 203.1.
  • the elevator car 205 is shown in a stop position, which lies above the desired stop position associated with the lower shaft door 203.2. In both of the stop positions shown, their distance from the desired stop position is so great that an opening of the cabin door leaf 207 is to be limited for the safety reasons explained above, which is achieved in the elevator installation according to the invention with the aid of the safety device described below.
  • These stationary stop cams 210 are preferably placed so that they lie as close as possible below the lower edge of each upper shaft door leaf 209.1 or above at the upper edge of each lower shaft door leaf 209.2, that their common vertical projection in the opening direction of the cabin door leaf with a defined distance next to that the ruler 208 is located.
  • the stop cams 210 protrude just so far beyond the cabin door-side surface of the shaft door leaf 209.1, 209.2, that they do not reach the shaft door-side surface of the cabin door leaf 207 (see also FIG. 3).
  • the stop cams 210 are able to stop the barrier ruler 208 and thus the car door leaf 207, if the elevator car 205 is so far above or below the target stop position that the barrier ruler 208 after a limited opening movement of the car door leaf 207 with one of the stationary stop cam 210 collided.
  • the length of the limited opening movement is determined by the above-mentioned distance, which is present in the opening direction of the cabin door leaf between the locking ruler 208 and the stationary stop cam 210. This distance is preferably chosen so that the opening path of the car door leaf - or the car door leaf - is limited only at a car door gap of at least 30 mm when the elevator car is positioned too far away from the target stopping position.
  • the stationary stop cams are preferably on stationary elements of the shaft doors 203.1, 203.2, for example on the landing door sills 214, on elements of the hoistway door frame 213 or on cladding elements 204 of the shaft doors.
  • the stationary stop cams 210 are placed outside the space occupied by the landing door wings 209.1, 209.2, so that they can be fully opened, although the elevator car 205 occupies a position in front of a shaft door in which a stop cam 210, the opening movement of the barrier rule 208 and thus the Cab door leaf 207 limited.
  • the prerequisite for the complete opening of the landing door wings in this situation is that the entrainment device 220 (see FIG. 3), which in the region of the desired stopping position of the elevator car couples the cabin door leaf with the shaft door leaf, does not fail due to a relatively large deviation of the cabin position from its desired stopping position more engaged.
  • Fig. 2 also shows that - in contrast to the stop plates according to the cited prior art - the stationary stop cam 210 always have unchanged dimensions even at different floor or door heights.
  • the height of the stop cam is advantageously at most 50 mm. Cost of materials and assembly costs are reduced, and the required material logistics is simplified accordingly.
  • the determination of the minimum required length of the barrier ruler 210 can be derived very easily. This always corresponds at least to the height of the landing door wings 209.1, 209.2, reduced by the sum of the upward and downward permissible deviations of the actual position of the Elevator car from its desired stop position. With the application of this rule for determining the length of the barrier ruler 210 ensures that with the smallest possible length of the barrier ruler, the intended functions of the security device can be realized.
  • Fig. 3 shows schematically a horizontal cross-section III-III through the upper car door / shaft door arrangement of the elevator system shown in Fig. 2.
  • the door-side shaft wall 202 two horizontal sliding shaft door 209.1 with the underlying shaft door sill 214, two corresponding with the landing door panels cabin door sash 207 with the underlying cabin door sill 216 and a portion of the elevator car 205.
  • With 208 are two vertically - ie perpendicular to Drawing surface - extending barrier rulers, each of which is attached to one of the car door wings 207.
  • the locking rulers 208 are arranged offset by a certain distance in the opening direction of the door two stationary landing cam 210 fixed to the shaft door sill 214, through which the opening path of the locking rulers 208 and thus the car door leaves 207 is limited if the elevator car too far below the Shaft door associated target stop position is located.
  • the still executable in this situation opening path leads to a door gap width, which is still narrow enough to prevent the fall of passengers in the elevator shaft, however, allows the communication between the maintenance personnel and trapped passengers and, for example, the catering of passengers.
  • Shown schematically in FIG. 3 are also two mentioned in connection with FIG. 2, between corresponding car door panels and landing door panels arranged entrainment devices 218, which transmit the door movements of the motor-driven cabin door panels 207 on the shaft door leaves 209.1.
  • FIG. 4 and 5 an advantageous embodiment of the attachment of a stop cam 210 on a shaft door sash 209 leading shaft door sill 214 is shown.
  • a block-shaped stop cam 210 is guided in a vertical groove 220 approximately 1 mm deep in the front wall 214.1 of the shaft door sill 214.
  • the stop cam 210 is provided with a vertically continuous T-shaped T-groove 221.
  • a special screw 222 is inserted with a T-groove adapted screw head of the lowest possible height, the screw shaft is inserted through a hole 223 in the front wall 214.1 of the shaft door sill 214.
  • the special screw 222 and with it the stop cam 210 is fixed to the shaft door sill 214.
  • the stop cam 210 is due to the guide in the vertical groove 220 in the horizontal direction, ie in the direction in which the locking bar 208 normally acts on him, strong loads.
  • the stop cam 210 can be pressed out of its fixation along the vertical groove, the required vertical force being dependent on the biasing force of the leaf spring 225.
  • This attachment of the stop cams can be of great advantage if the barrier ruler 208 due to a malfunction of the elevator control with vertically moving elevator car 205 and at least partially open cabin door leaves 207 on one or several of the stop cam 210 hits. Greater damage to the elevator installation can be avoided thanks to the illustrated embodiment of the stop cam attachment.
  • a correspondingly adapted fastening of the stop cams to elements of the shaft door 203.1, 203.2, for example on the door striker of the shaft door frame 213 or on covering elements 204 of the shaft door, can of course also be realized.
