| 20080236954 | METHOD OF PREVENTING COLLISION OF TWO ELEVATOR CARS MOVABLE IN THE SAME SHAFT OF AN ELEVATOR INSTALLATION, AND CORRESPONDING ELEVATOR INSTALLATION - A method of preventing a collision of two elevator cars of an elevator installation, which cars move substantially independently of one another in a common shaft, and an elevator installation includes a collision protection system that produces a retardation of each moved elevator car by a stopping brake as soon as the effective distance between the elevator cars falls below a critical minimum distance. After retardation of the cars by the stopping brakes, an emergency stop system comes into function. A control system of this emergency stop system ascertains the instantaneous movement state of the elevator cars. With the help of the car brakes, which are associated with the elevator cars, an additional retardation of each moved elevator car is triggered when the movement state thereof fulfils definable emergency stop criteria. | 10-02-2008 |
| 20080302610 | ELEVATOR WITH TWO ELEVATOR CARS WHICH ARE DISPOSED ONE ABOVE THE OTHER IN A SHAFT - An elevator has at least two elevator cars, which are disposed one above the other in a shaft, which cars are vertically movable and which each have a drive, a counterweight and a traction device, wherein one drive is fixed at a first shaft wall and a second drive is fixed at an opposite second shaft wall and each drive has at least one drive pulley. At least one first deflecting roller is associated with each drive and is positioned the shaft wall that is opposite the drive and above the counterweight associated with the drive. The traction device is led from the counterweight over the deflecting roller to the drive pulley and from there to the elevator car. | 12-11-2008 |
| 20100089705 | APPARATUS AND METHOD FOR HOLDING AND BRAKING AN ELEVATOR CAR - An elevator car with brake equipment, which is arranged in the region of the elevator car, for holding and braking the same, which brake equipment includes: a brake unit which can co-operate with a brake rail, an actuating device which can produce an actuator force F | 04-15-2010 |
| 20100133046 | ELEVATOR SYSTEM, SUSPENSION ELEMENT FOR AN ELEVATOR SYSTEM, AND DEVICE FOR MANUFACTURING A SUSPENSION ELEMENT - An elevator system with a car or platform to transport passengers and/or goods as well as with a counterweight, which are arranged as traversable or movable along a travel path, and which are coupled and/or with a drive by a suspension element interrelating their motion. The suspension element is guided and/or driven by a traction sheave and/or a drive shaft and/or a deflecting pulley. The suspension element is sheathed and/or belt-type, with a first layer made of a first plasticizable and/or elastomeric material, containing a first exterior surface, and with at least one tension member—rope-type, tissue-type, or comprising a multitude of partial elements—that is embedded in the first layer of the suspension element. A manufacturing procedure for one of the suspension elements is provided. | 06-03-2010 |
| 20110005867 | ELEVATOR SYSTEM WITH TWO ELEVATOR CARS - An elevator system has two elevator cars arranged one over the other, but that can travel independently of each other. Both elevator cars are suspended on suspension and traction mechanisms and each is coupled to a separate counterweight. Both elevator cars have a lower cable, wherein the two lower cables are tensioned by separate tension devices. The lower cable of the first, lower elevator car is fastened to the first elevator car and the first counterweight, The lower cable of the second, upper elevator car is guided at the second elevator car and at least one of the two lower cable ends thereof is secured by a weighted body secured in place with play and/or free-floating. | 01-13-2011 |
| 20110024239 | OPERATING METHOD FOR AN ELEVATOR WITH TWO ELEVATOR CARS AND A COUNTERWEIGHT - Evacuation method for a lift with at least three lift bodies which are moved along at least one travel path and are connected together by way of support and traction means, wherein the first and the second lift bodies are suspended 1:1 by means of the support and traction means and the third lift body is suspended 2:1 by means of the support and traction means. The three lift bodies can each be blocked by way of a respective controllable blocking device. If passengers are present in a first one of the three lift bodies a further second or third lift body is blocked. In the case of presence of an imbalance between the weight masses of the two remaining unblocked lift bodies the first lift body is moved to an evacuation storey. | 02-03-2011 |

| 20110120809 | COLLISION BRAKE FOR TWO ELEVATOR BODIES MOVING INDEPENDENTLY OF ONE ANOTHER - A collision brake for two elevator bodies, which move independently of one another, includes a first locking mechanism, which is disposed between the two elevator bodies and is fastened on a first of the two elevator bodies, and which has a brake body arrangement having at least one first brake body, which is movably mounted in the first locking mechanism toward a guide structure. The first locking mechanism has a positive guide, which converts a relative movement of the brake body arrangement in an ascension direction by the second of the two elevator bodies into a relative movement of the brake body arrangement on the guide structure. | 05-26-2011 |
