20150321883 | SAFETY BRAKE FOR AN ELEVATOR INSTALLATION - In an elevator installation an elevator car is movable along at least two guide rails and the car is equipped with a pair of safety brakes and an actuator for actuating the safety brakes. Each safety brake includes at least one brake eccentric with a cylindrical bearing bore and a brake housing with a bearing axle for mounting the brake eccentric. The bearing axle is arranged in the brake housing together with the brake eccentric to be pivotable or displaceable so that the brake eccentric, which is arranged on the bearing axle, in a first position can be kept at a spacing from a brake web of the guide rail and in a second position can be brought into contact with the brake web. | 11-12-2015 |

20080296098 | Brake Shoe for Elevator Emergency Stop - The present invention prevents cracking of a brake shoe even when the sliding surface of the brake shoe is heated to a high temperature and provides high reliability. The present invention provides a brake shoe for elevator emergency stop which generates a braking force by pressing brake shoes against a guide rail and making the brake shoes | 12-04-2008 |
20090020371 | Elevator evacuation apparatus - An elevator evacuation apparatus is disclosed. The apparatus is adapted to enable person(s) trapped in a stopped elevator car to pull a cable outside a car window to activate a cam based pulley and gear mechanism which in turn intermittently releases and actuates a brake, thereby slowly lowering the stopped car until arriving a correct floor. A number of embodiments are possible. | 01-22-2009 |
20120175194 | ELEVATOR TENSIONING SHEAVE APPARATUS - A tensioning sheave apparatus main body has a tensioning sheave around which the speed governor rope is wound. The tensioning sheave apparatus main body is suspended on the speed governor rope to apply tension. Vertical displacement of the tensioning sheave apparatus main body is guided by a tensioning sheave rail. A braking force generating apparatus suppresses upward displacement of the tensioning sheave apparatus main body by a braking force that is generated by gripping the tensioning sheave rail. The braking force generating apparatus allows the upward displacement of the tensioning sheave apparatus main body when the magnitude of an upward force that acts on the tensioning sheave apparatus main body is greater than or equal to a fixed value. | 07-12-2012 |
