187343000 | HAVING MEANS CUSHIONING CONTACT OF LOAD SUPPORT WITH TERMINUS OF SHAFT | 8 |
20080230324 | Frangible Buffer For An Elevator System With Multiple Cars In A Hoistway - An elevator system ( | 09-25-2008 |
20080289909 | Elevator Shock Absorber - A car shock absorber is positioned on a pit floor car between a car guide rail and the pit floor and/or between the car or counterweight and the pit floor. The car shock absorber has a shock absorbing body made of a deformable material in which a recess is formed. A pressing body is continuously engaged in the recess. When a shock load is input to a top part of the pressing body, the load is distributed in a direction perpendicular to inclined pressure and pressure-receiving surfaces, which are the contact surfaces between the pressing body and the shock absorbing body, thereby reducing the shock stress produced in the pit floor. | 11-27-2008 |
20100243379 | BUFFER ARRANGEMENT AND BUFFER STOP OF AN ELEVATOR - The object of the invention is a buffer arrangement of an elevator, which comprises at least the buffer ( | 09-30-2010 |
20110240413 | Safety Devices for Elevators with Reduced Clearances - In an elevator shaft ( | 10-06-2011 |
20120255811 | FLOOR FOR AN ELEVATOR CAGE - A floor for an elevator cage has a base plate, a top plate and a support structure arranged therebetween. The support structure comprises a grating arrangement including a plurality of intersecting profile members standing on edge. For local reinforcement, the support structure additionally includes a second grating arrangement superimposed on the first arrangement. | 10-11-2012 |
20140360818 | ELEVATOR SYSTEM INCLUDING A CAR STOP FOR MAINTAINING OVERHEAD CLEARANCE - An exemplary elevator system includes an elevator car. At least one guiderail is situated for guiding movement of the elevator car. A machine mount is supported by the guiderail near a top of the guiderail. A car stop is supported on the elevator car. The car stop is selectively moveable between a first position and a second position. In the first position the car stop allows the elevator car to travel to a maximum vertical position. In the second position the car stop is situated to contact the machine mount to prevent the elevator car from reaching the maximum vertical position. | 12-11-2014 |
187344000 | Fluid resistance or shock absorber-type means | 2 |
20080302612 | Elevator Car with Fold-Away Shock Absorbing Legs, and the Corresponding Elevator - The invention pertains to an Elevator car with a lower chassis ( | 12-11-2008 |
20100307871 | OIL BUFFER FOR AN ELEVATOR - In an oil buffer for an elevator, at least one cylindrical intermediate plunger is inserted into a base cylinder. An upper-stage plunger is inserted into the intermediate plunger. An orifice is provided in a bottom surface portion of the upper-stage plunger. A pin rod is provided upright in the base cylinder. The pin rod is inserted into the orifice in a middle of a stroke of the upper-stage plunger. A return spring causes the intermediate plunger and the upper-stage plunger to return to positions in an unloaded state. | 12-09-2010 |
