Definitions
- the invention relates to an elevator installation with a shaft in which at least two cars are arranged one above the other and can be moved vertically upwards and downwards, whereby each car has one
- Drive device is assigned to the process of the car and a brake device is arranged on each car, and with a safety device for monitoring the driving behavior of the car, and with at least one Fahrwegbegrenzungs announced, the at least one arranged on a car stop element and cooperating with this, arranged in the shaft Holding element, for limiting the travel of the car.
- people and loads can be moved.
- Each car is associated with a drive means for moving the car vertically upwards and vertically downwards.
- the drive device comprises a drive motor and a drive brake.
- the elevator systems In order to avoid an unchecked collision of two cars in the event of a malfunction, the elevator systems have a safety device with which the driving behavior of the cars monitored and, if necessary, an emergency stop can be triggered. In an emergency stop, the drive motor of the car is switched off and the drive brake is activated.
- a braking device is arranged on each car, such as a safety gear, with which the car can be mechanically braked when falling below a safety distance to an adjacent car.
- a track limiting device is usually used for the lowest car with at least one stop element, which is arranged on the lowest car, and with a arranged at the lower end of the shaft in the so-called shaft pit holding element.
- the holding device is in this case usually designed in the form of a buffer element, which is arranged within the vertical projection of the lowermost car in the shaft pit.
- the brake device arranged on the car in particular a safety gear, is usually triggered in the event that the car falls below a predetermined safety distance to a second car arranged in front of the car in the direction of travel.
- the safety distance is selected such that the car can be braked safely after triggering the braking device without colliding with the arranged in front of him second car. A collision can be reliably prevented.
- the required safety distance between two adjacent cars is often greater than the distance between two immediately adjacent floors of a building in which the elevator system is installed. This has the consequence that two cars can not be positioned simultaneously in immediately adjacent stops and limits the transport capacity of the elevator system.
- Object of the present invention is to develop an elevator system of the generic type such that their transport capacity can be increased.
- At least one stop element is arranged on a first car, which protrudes laterally in a stop position from the vertical projection of the first car and together with a certain, this stop element associated holding element together.
- Menwirkt which is arranged outside the vertical projection of all movable in the slot car and is freely passable from all other moving in the slot cars, and that the respective car arranged braking device or its braking effect can be deactivated when the car falls below a predetermined speed limit, the Car at speeds up to the maximum limit speed by means of the stop and the holding element can be braked to a stop.
- a vertical projection of a car is understood to mean a projection of a car in the vertical direction onto a horizontal plane, for example onto the shaft bottom.
- a holding element is arranged on at least one car which can assume a stop position in which it protrudes laterally from the vertical projection of the first car.
- the stop member cooperates to limit the travel of this car with a particular holding element, which is arranged in the shaft outside the vertical projection of all cars. Approaches the car with less
- the associated holding element that is at a speed which is less than the predetermined limit speed
- the associated holding element, the brake device arranged on the car or its braking effect can be deactivated and the limitation of the travel can be carried out in case of malfunction by the stop element and the associated holding element.
- the stop and the holding element are for this purpose designed such that they can decelerate the car to a stop by the stopper member impinges on the associated holding element.
- the stop element projects laterally out of the vertical projection of the car so that it can contact the associated holding element.
- the associated retaining element limits this only the track of this one car, whereas the remaining cars from this holding element in their ride not be affected.
- the function of the brake device arranged on the car can thus be taken over at low speeds, ie at speeds less than the limit speed, from the stop and the associated holding element. If a second car is arranged in the region of the holding element assigned to a first car, then the first car can approach the second car very closely at low speed.
- the safety distance which is decisive for the triggering of the braking device, can be undershot, without the braking device is active. This or their braking effect can be deactivated and in the event of a fault, the car can be brought to a halt by means of the stop and the retaining element.
- the limit speed below which the braking device is deactivated for example, may be smaller than the achievable in conventional deceleration control devices known elevator systems reduced impact speed of the buffer elements of such elevator systems, this reduced impact speed may be dependent on the rated speed of the elevator systems.

For the other cars, this holding element is no harm.
- the first car is arranged above a second car. If, for example, the second car occupies a position at the lowermost stop of the elevator installation, then the first car can enter the stop directly above it, even if the stops have only a relatively small vertical distance from one another. A collision of the first car with the second car can be reliably prevented in the event of malfunction of the elevator system by providing the projecting in the stop position laterally from the vertical projection of the first car stop element and its associated holding element without the braking device of the first car must be activated.
- the second car may be assigned a buffer element arranged below the second car within the vertical projection of the second car, with the aid of which a collision of the second car with underlying parts of the elevator system or the pit may be damped.

It can also be provided that in the area between the shaft pit and the shaft head a retaining element outside the vertical projection of all Riders rather baskets is arranged in the shaft, which cooperates to limit the travel of one of the cars with a particular stop element of a car that protrudes in a stop position outside the vertical projection of this car. This gives, for example, the possibility of dividing the shaft into an upper and a lower shaft area, wherein an upper car can be moved in the upper shaft area and a lower car can be moved in the lower shaft area.
- Shaft areas can adjoin one another directly even at small intervals of the stops provided in the individual floors.
- the lower stop of the upper shaft area can be approached by the upper car and at the same time, the uppermost stop of the lower shaft area can be approached by the lower car.

- the possibility of positioning at immediately adjacent stops leads to an increase in the transport capacity of the elevator system.
- the cars are usually connected via support means each with a counterweight.
- a support means for example, carrying ropes or straps can be used.
- the counterweights perform a movement opposite to the respective associated car as the car moves up or down. In order to limit the travel path of a car, the movement of its counterweight can also be limited, without affecting the movement of the other counterweights. is pregnant.

- the first car can be arranged, for example, above the second car and a downward travel of the first car can be limited by means of the projecting in a stop position laterally from the vertical projection of the first car stop element and this stop element associated holding element.
- the upward movement of the second car can be limited.
- At least one arranged on a car or on a counterweight stop element is held in an advantageous embodiment of the invention immovably on the car or on the counterweight. This allows a structurally particularly simple and inexpensive to produce embodiment of the elevator system. It can also be provided that at least one retaining element is held immovably in the shaft.
- the travel of the respective car by means of the stop and the associated holding element, without the braking device must be used.

- a collision of two cars can be reduced, for example, in the event that the cars retract into each other directly adjacent stops of the elevator system by means of cooperating stop and support elements. In this state, the cars no longer have their rated speed, but a significantly reduced speed, otherwise the safety device of the elevator system would already respond when entering the stop. If the stop or holding elements have a buffer element, it is therefore not absolutely necessary to design the buffer element to the nominal speeds of the cars.

- the first stop element 54 is immovably fixed to the first car 14 and projects laterally toward the shaft side wall 44 from the vertical Projection of the first car 14 forth.
- the second stop element 56 is movably held on the first car 14, in the illustrated embodiment it is pivotable about a first pivot axis 58 between a release position shown obliquely in FIG. 1 and a horizontally oriented stop position shown in FIG.
- first holding element 60 which is arranged in the shaft 12 outside the vertical projection of both cars 14, 16 and which is fastened to the shaft side wall 44 in the exemplary embodiment shown.
- the second stop element 56 is associated with a shaft 12 outside the vertical projection of all the cars 14, 16 arranged second support member 64 which is fixed in the illustrated embodiment, the shaft bottom 68 of the shaft 12.
- the first holding element 60 has, just like the second holding element 64, a buffer element 70 which is fastened outside the projection of all the cars 14, 16 in the shaft 12.
- the buffer element 70 may, for example, in Form of a hydraulic buffer or be designed in the form of an elastomeric buffer.
- the first stop element 54 When traveling downwards, the first stop element 54 hits the first holding element 60 when a lower end position of the first car 14 is reached, thereby limiting the travel path of the first car 14 vertically downwards.
- the second stop element 56 insofar as it assumes its horizontally oriented stop position, hits the second holding element 64 when the first car 14 reaches a lower end position when the first car 14 reaches a lower end position and thus also limits the travel path of the first car 14 vertically below.
- the second car 16 is associated with a third stop element 72 which is fixed immovably on the second car 16 and protrudes laterally from the vertical projection of the second car 16.
- the third stop element 72 faces the shaft side wall 44.
- a fourth stop element 74 is movably held on the second car 16.
- the fourth stop member 74 is movable about a second pivot axis 76 between an obliquely upwardly directed, shown in Figure 1 release position and a horizontally oriented, shown in Figure 2 stop position back and forth.
- the third stop element 72 is associated with a third holding element 78, which is arranged in the shaft 12 outside the vertical projection of all the cars 14, 16.
- the third retaining element 78 is fixed to the shaft side wall 44.
- the fourth stop element 74 is associated with a fourth holding element 82 arranged in the shaft 12 outside the vertical projection of all the cars 14, 16 and held on the shaft ceiling 86 of the shaft 12.
- the third stop element 72 strikes upon reaching an upper end position of the second car 16 on the third holding element 78. As a result, the travel of the second car 16 is limited vertically upwards.
- the fourth stop element 74 if this assumes its horizontally oriented stop position, reaches the fourth holding element 82 when an upper end position of the second car 16 is reached, as a result of which the travel path of the second car 16 is also vertically upwards is limited.
- the third holding element 78 has, just like the fourth holding element 82, a buffer element 70 which absorbs at least part of the impact energy when the stop elements 72, 74 strike the holding elements 78, 82 and thereby dampens the impact.
- the holding elements 60, 64, 78 and 82 are arranged outside the vertical projection of the cars 14 and 16 and of course also outside the vertical projection of the counterweights 20 and 30.
- the holding elements 60, 64, 78 and 82 each act only with a very specific stop element of the cars 14 and 16 together, if this stop element assumes its stop position. The interaction takes place in such a way that in each case a specific stop element can impinge on a particular holding element, provided that the stop element assumes its stop position in which it protrudes laterally from the vertical projection of the respective car 14 and 16 respectively. This makes it possible to selectively limit the travel path of a particular car 14 or 16 with the aid of at least one stop element and a holding element associated with this stop element.
- the travel path of the respective car 14 or 16 can be temporarily reduced by the respective stop element 56 and 74 is pivoted into its stop position, in which there is a particular holding element 64 and 82 for limiting the driveway can interact. If the route is not limited, the respective stop element 56 or 74 can be pivoted into its release position shown in FIG. 1, in which it can not interact with any of the holding elements arranged in the shaft.
- the holding elements could be movably mounted so that they can temporarily limit the travel of a car in a holding position in cooperation with the respective associated stop element, whereas they do not limit the travel in a release position.
- the braking device 55 or 57 arranged on the respective car 14, 16 or its braking effect 55 or 57 is deactivated.
- the provision of the first stop element 54 and the second stop element 56 and the stop elements respectively associated holding elements 60 and 64 are in combination with the speed-dependent deactivation of the braking devices 55, 57 the ability to position the first car 14 at a stop, which is a lowermost Stop of the elevator system 10 is immediately adjacent, wherein in the lowest station, the second car 16 is positioned and wherein the distance between the cars 14 and 16 is smaller than the safety distance.
- the first car 14 can approach the second car 16 very strongly at a speed that is less than the predetermined limit speed without the brake device 55 being released when the safety distance is undershot.
- the provision of the stop and retaining elements 54, 56 and 60, 64 rather ensures that the first car 14 can not collide with the second car 16 arranged thereunder.
- the stop members 54 and 56 hit the holding members 60 and 64 and thereby block a further downward movement of the first car 14th
- the stop elements 72 and 74 arranged on the second car 16 ensure, in combination with the holding elements 78 and 72 associated with these stop elements, that the second car 16 can assume a position in a stop which directly follows an uppermost stop of the elevator system 10 is adjacent, wherein in the uppermost stop of the first car 14 is arranged.
- the second car 16 can approach the first car 14 at a speed that is less than the predetermined limit speed without causing the brake device 57 to fall below the safety distance.
- a collision of the second car 16 with the first car 14 is reliably prevented by the stop elements 72, 74 in combination with the holding elements 78 and 82.
- Buffer 70 of the holding elements 60, 64, 78, 82 designed for a maximum impact speed, which corresponds to the predetermined limit speed. This may for example be 3 m / s or 2 m / s or only 1 m / s.
- the required buffer path can thus be kept relatively low. If the speed of a car 14, 16 falls below the limit speed when approaching the associated holding elements, then the braking device 55 or 57 can be deactivated and the car 14, 16 reliably stopped in the event of a malfunction by means of the buffer elements 70.
- FIG. 3 shows a second embodiment of an elevator installation according to the invention which is designated overall by the reference numeral 100.
- This is designed substantially identical to the elevator system 10 explained above with reference to FIGS. 1 and 2, for identical components Therefore, the same reference numerals are used in Figure 3 as in Figures 1 and 2 and with respect to these components reference is made to avoid repetition to the above explanations.
- the elevator system 100 differs from the elevator system 10 in that the buffer elements 70 are not arranged on the holding elements 60, 64, 78 and 82, but the buffer elements 70 are on the stop elements 54, 56 and 72 in the elevator installation 100 shown in FIG , 74 held. Again, by means of the buffer elements 70 upon impact of the stop members 54, 56 on the support members 60 and 64 and the impact of the stop members 72 and 74 on the support members 78 and 82, the impact energy can be absorbed after the braking devices 55, 57 at a slow approach to the retaining elements 60, 64, 78, 82 have been deactivated.
- the travel path of the cars 14 and 16 can be temporarily reduced by the use of only the movable stop elements 56 and 74 by these stop elements 56, 74 are pivoted in their horizontally oriented stop position. If a temporary reduction of the travel path is not required, the stop elements 56, 74 can be pivoted into their release position.
- FIGS. 4 and 5 show a third embodiment of an elevator installation 110 according to the invention, which is designed substantially identical to the elevator installations 10 and 100 explained above.
- the elevator installation 110 shown in FIGS In the following, the elevator installation 130 illustrated in FIG. 6 uses identical reference symbols as in FIGS. 1, 2 and 3 and with respect to these components reference is made to the above explanations in order to avoid repetition.
- the elevator installations 110 and 130 are shown in sectional views in FIGS. 4 and 6, which extend perpendicular to the shaft rear wall 42 and thereby the arrangement of the counterweights 20, 30 laterally side by side and the area between the counterweights 20, 30 and the shaft rear wall 42 make clearer.
- stop elements are not arranged on the cars 14, 16 but on the respective counterweights 20 and 30. These stop elements also each act with a specific holding element arranged in the shaft 12 together to limit the travel of the respective counterweight 20 and 30 and thus also the travel of the respective associated car 14 and 16 respectively.
- a fifth stop member 114 is held on the rear wall 112 of the first counterweight 20 facing the rear wall 42 projecting laterally from the vertical projection of the first counterweight 20 and that during a downward travel of the first car 14, that is at a movement of the first counterweight 20 vertically upward, upon reaching a lower end position of the first car 14 with a fixed to the shaft rear wall 42 fifth support member 116 which has a buffer member 70, as already described above with reference to Figures 1, 2 and 3 was explained.
- the fifth stop element 114 is movably held on the first counterweight 20 and can be moved back and forth between an obliquely upwardly directed release position shown in FIG. 4 and a horizontally aligned stop position facing the shaft rear wall 42 as shown in FIG.
- the fifth stop member 114 is pivotally mounted about a third pivot axis 118 on the first counterweight 20.
- the fifth stop element 114 can be pivoted into its stop position. If the travel path of the first counterweight 20 and thus also the travel path of the first car 14 are not limited, then the fifth stop element 114 can assume its release position.
- the braking device 55 can be deactivated. If the speed of the first car 14 is less than the limit speed, then the braking device 55 can be deactivated. If the second car 16 is located in the lowermost stop of the elevator installation 110, the first car 14 can approach the second car at low speed, ie a speed which is less than the limit speed, without the brake device 55 being released. In the case of a malfunction of the elevator installation 110, the first car 14 is braked by the fifth stop element 114 impacting the buffer 70 of the fifth retaining element 116. This limits the travel path of the counterweight 20 and thus also the travel path of the first car 14.
- the second counterweight 30 of the elevator installation 110 shown in FIG. 4 carries a sixth stop element 122 on its rear wall 120 facing the shaft rear wall 42, which moves vertically upward when the second elevator car 16 ascends, ie when the second counterweight 30 moves upper end position of the second car 16 cooperates with a sixth holding element 124, the
- the elevator system 110 is fixed and has a buffer element 70.
- the sixth stop element 122 strikes the buffer element 70 of the sixth retaining element 124 upon reaching an end position predetermined by the positioning of the sixth retaining element 124 and thereby limits the travel path of the second counterweight 30 and thus also the travel path of the second car 16 ,
- the braking device 57 can be deactivated. If the speed of the second car 16 is less than the limit speed, then the braking device 57 can be deactivated. If the first car 14 is located in the uppermost stop of the elevator installation 110, the second car 16 can approach the first car 14 at a speed which is less than the limit speed without the braking device 57 being triggered. In the event of a malfunction of the elevator system 110, the second car 16 is braked by the sixth Stop element 122 impacts the buffer 70 of the sixth support member 124. This limits the travel path of the counterweight 30 and thus also the travel path of the second car 16.
- the sixth stop element 122 interacts only with the sixth holding element 124, so that the travel path of the second counterweight 30 and thus also the travel path of the second car 16 can be specifically limited by means of these two components.
- the fifth stop element 114 cooperates only with the fifth holding element 116, so that only the travel path of the first counterweight 20 and thus also the travel path of the first car 14 can be limited by means of these two components.
- the elevator installation 130 shown in FIG. 6 is substantially identical to the elevator installation 110 shown in FIG. 4.
- the elevator installation 110 differs from the elevator installation 110 merely in that the buffer elements 70 are not arranged on the fifth and sixth holding elements 116 and 124, respectively at the respectively associated stop elements 114 and 122.
- the travel paths of the counterweights and cars can be limited by means arranged on the counterweights stop elements and their respective associated holding elements.
- the stop elements protrude laterally from the vertical projection of the counterweights and the holding elements are positioned outside the vertical projection of all counterweights in the shaft 12.
