20130048435 | ELEVATOR INSTALLATION ACCESS SECURITY METHOD WITH POSITION DETECTION - A method of operating an elevator installation for transporting elevator users in a building area, including the steps of: detecting the position of elevator users in the building area, granting of an access authorization of the elevator users to building regions, triggering of a destination call by a detected elevator user, allocation of an elevator car serving the destination call or elevator call, boarding of an elevator car by at least one detected elevator user, if an elevator call was triggered triggering a car call by a detected elevator user, comparing whether the position of the elevator user that has boarded the elevator car corresponds with the position of the elevator user that has triggered the destination call, and determining whether the elevator user that has boarded the elevator car has an access authorization for a destination location corresponding with the destination call or elevator call. | 02-28-2013 |
20130081906 | MONITORING SHAFT DOORS - An elevator installation has at least one shaft door and a monitoring device for monitoring movements for opening the shaft door, the monitoring device comprising a first, energy-autonomous counting device for counting the movements, which independently of an intact power supply increments a first count value in the case of one of these movements, and a second counting device for counting the movements, which when the power supply is intact increments a second count value in the case of one of these movements, and a comparison circuit which calls up and compares the first and second count values and can generate a signal based on the comparison of the count values. | 04-04-2013 |
20130092479 | ELEVATOR - A car for an elevator, which is movable in an elevator shaft, has a car roof projecting at least partly beyond a drive unit. Arranged on the car roof in the region of the side facing the drive unit is a balustrade which has a handrail interrupted centrally in a drive receiving region. The balustrade has in the drive receiving region a bar which is arranged to be offset downwardly and inwardly relative to the handrail. | 04-18-2013 |
20130098714 | SLIDING GUIDE SHOE FOR AN ELEVATOR - A sliding guide shoe for an elevator for conveying persons or goods includes a guide shoe housing and a two-part insert, which insert is inserted in the guide shoe housing for guiding an elevator car along a guide rail extending in a longitudinal direction. The insert includes a slide element connected with a support element and removable laterally from the sliding guide shoe in the longitudinal direction. The slide element is insertable into or removable from the support element only from one longitudinal side. | 04-25-2013 |
20130118836 | ELEVATOR WITH SAFETY DEVICE - An elevator includes an elevator cage, a drive arrangement, a first safety controller and a second safety controller, wherein the first and the second safety controllers monitor a state of the elevator respectively by means of at least one first or second sensor and on detection of an unsafe state institute a measure in order to bring the elevator into a safe state. The first safety controller is arranged on the elevator cage and the second safety controller is arranged in the region of the drive arrangement. | 05-16-2013 |
20130133984 | SAFETY BRAKE WITH RESETTING - In an elevator installation an elevator cage is arranged to be movable along guide rails and the elevator cage is equipped with a brake system possibly with two safety brakes. The safety device is activated by way of control devices which can trigger the safety device from critical or non-critical events. The control devices further include a function for automatic resetting of the safety brake when an event, which is evaluated as non-critical, is indicated as a reason for triggering the safety brake. Resetting of the safety brake takes place through execution of pre-defined resetting steps of the elevator cage. | 05-30-2013 |
20130153340 | CHECKING STATES IN AN ELEVATOR INSTALLATION - An elevator installation includes a cage, a counterweight, a drive and at least one support element. The cage and the counterweight are supported by the support element, which is driven by the drive to move the cage and the counterweight in opposite directions. The support element includes at least one test element, wherein the test element is contacted by at least one contacting device and connected with a measuring device so that an electrical resistance of the test element is determinable by the measuring device, wherein the electrical resistance of the test element changes due to stretching of the test element so that through measurement of the electrical resistance of the test element at least one of the following states of the elevator installation is ascertainable: loading of the cage, a slack support element, a tension difference between at least two support elements and damage of the support element. | 06-20-2013 |
20130157497 | ELECTRICAL CONTACTING OF TENSILE CARRIERS IN SUPPORT COMPONENTS - A system for electrical contacting of tensile carriers in support means includes a support means and a contacting device. The support means has a casing and at least four tensile carriers. The tensile carriers are arranged parallel to one another in the casing and lie substantially in one plane. The contacting device has a contact element. The contact element has a cutting side for penetration of the casing, wherein the cutting side of the contact element is so guided through the casing that the contact element contacts the at least four tensile carriers at least by the cutting side. | 06-20-2013 |
20130161131 | SAFETY DEVICE FOR AN ELEVATOR WITH A PLURALITY OF CAGES - An elevator has a first and a second cage, which are movable along a common travel path. In addition, the elevator includes a safety device, by which the two cages can be monitored, and a shaft information system, which is connected with the safety device and by which the speed and the position of the two cages can be determined. If the two cages fall below a safety spacing, a first braking measure can be initiated for at least a first cage by means of the safety device. A retardation plot for the at least first cage is predeterminable by the safety device on initiation of the first braking measure. In that case, a second braking measure can be initiated for the at least first cage by means of the safety device if the retardation plot is exceeded. | 06-27-2013 |
