| 20100078268 | ELECTRIC SAFETY SWITCH RESETTING DEVICE FOR A CAR SAFETY DEVICE OF ELEVATORS - The invention pertains to an electric safety switch ( | 04-01-2010 |
| 20100155181 | ELEVATOR INSTALLATION WITH REDUCED HOISTWAY DIMENSIONS - An elevator system comprises a hoistway ( | 06-24-2010 |
| 20100155184 | ELEVATOR HAVING A SHALLOW PIT AND/OR A LOW OVERHEAD - The elevator has a car movable vertically within a shaft between lower and upper end positions and a drive system coupled to a traction system for controlling movement of the car. A limit switch which is open when the car is in a selected distance range from one of the end positions. The limit switch forms part of a power line supplying power to the drive system for controlling movement of the car in a direction towards that end position in an inspection operation. Thus movement of the car is prevented only in that direction when the car is in the selected distance range in an inspection operation. | 06-24-2010 |
| 20100163346 | SAFETY DEVICE FOR SECURING MINIMUM SPACES AT THE TOP OR BOTTOM OF AN ELEVATOR SHAFT BEING INSPECTED, AND ELEVATOR HAVING SUCH SAFETY DEVICES - The safety device for an elevator system comprises a retractable element mounted on a support. The retractable element has a stopping position in which a catch portion of the retractable element projects from the support to engage a triggering member of a safety brake associated with an elevator car as the elevator car traveling in a selected direction approaches a selected vertical position, and a retracted position. An actuator selectively controls the position of the retractable element. A position sensor is responsive to the position of the retractable element to make sure that it is in its stopping position when needed. | 07-01-2010 |
| 20110061978 | VIBRATION ISOLATION ASSEMBLY FOR AN ELEVATOR SYSTEM - An exemplary vibration isolation assembly for use with elevators includes a first rigid member having an outer wall at least partially surrounding a central opening. A second rigid member is at least partially received within the central opening of the first rigid member. A resilient layer between the first and second members substantially isolates the first member from vibrations of the second member. | 03-17-2011 |
