187336000 | WITH CLOSURE MEANS FOR SHAFT OPENING THROUGH LANDING | 11 |
20120305337 | ELEVATOR SHAFT CLOSURE DOOR FRAME - A door frame of an elevator shaft closure has a chamber in which an elevator control arrangement is arranged. The elevator shaft closure separates an elevator shaft of a building from a story of the building. The elevator control arrangement includes an elevator control unit and at least one electronic power unit, which is connectible with an elevator motor. | 12-06-2012 |
20130075202 | VISUAL WARNING BARRIER FOR DOOR ASSEMBLY USED IN A VERTICAL LIFTING SYSTEM - A vertical reciprocating conveyor has a carriage mounted for movement in a support frame between different designated vertical levels, a door assembly mounted on the support frame for gaining access to the carriage when the carriage is at the one designated level. A visual warning barrier is movably mounted between a raised, inoperative position and a lowered, operative position across a doorway formed in the support frame at the one designated level. The visual warning barrier is automatically moved from the raised, inoperative position to the lowered, operative position upon movement of the door assembly to the open position when the carriage is located away from the one designated level. | 03-28-2013 |
20140246276 | INSULATED LANDING DOOR OF AN ELEVATOR - The object of the invention is an insulated landing door of an elevator, which door comprises at least one door panel that opens and closes in the lateral direction and is provided with a glass surface plate, which door panel comprises a frame structure supporting the door panel and an edge beading on the front edge of the door panel and an insulation element. The insulation element is composed of one or more glass plates, and that there is an air gap between the glass surface plate and the glass insulation element. | 09-04-2014 |
20150060211 | FALL PREVENTION DEVICE FOR AN ELEVATOR - A fall prevention device includes a shaft extending vertically through a multi-story building. A door is provided on each floor of the multi-story building. A cab is movably mounted in the shaft and includes a cab door. A movement device includes a power mechanism and first and second grid structures directly or indirectly connected to the power mechanism. The first and second grid structures are respectively fixed to top and bottom sides of the cab at locations adjacent to the cab door. Each of the first and second grid structure includes a plurality of rails spaced from each other in a width direction perpendicular to the vertical direction. The movement device further includes a first support device in a top end of the shaft and a second support device in a bottom end of the shaft. The first and second support devices respectively support the first and second grid structures. | 03-05-2015 |
20150321882 | ELEVATOR AND MEANS FOR FORMING A SAFETY SPACE - An elevator includes at least an elevator car arranged to move reciprocally in an elevator hoistway and fitted on guide rails, a plurality of landing doors having landing door locks openable e.g. with a service key, and a safety arrangement arranged to form a safe space, preferably a working space, in the elevator hoistway below the elevator car, access to which safe space is enabled via at least one landing door in the proximity of the base of the elevator hoistway, and/or a safe space, preferably a working space, above the elevator car, to which access is enabled via at least one landing door leading to the roof of the elevator car, and in which elevator the aforementioned safe space has a minimum height. The formation of each safe space is arranged to be implemented as a consequence of the opening occurring, e.g. with a service key, from a floor level of a landing door enabling access into the elevator hoistway. | 11-12-2015 |

187337000 | Including pivoted closure | 1 |
20150096842 | MINING ELEVATOR CARRYING PLATFORM AND CARRYING METHOD - A mining elevator carrying platform and carrying method, the platform comprises a power system ( | 04-09-2015 |
187340000 | Including transversely sliding closure | 3 |
20110147132 | ELEVATOR DOOR SYSTEM - An elevator door system includes a door drive and a door wherein the door drive has a horizontally movable, vertically aligned beam and the door has a fast panel and one or more successively slower panels and a first synchronous linkage mechanism including a series of links extending alternatively upwards and downwards between a first pivot point mounted to a door frame and a further pivot point mounted to the fast panel. A drive lever is connected to the first synchronous linkage mechanism and engages with the vertically aligned beam so that horizontal movement of the beam is translated by the drive lever into rotation of the first synchronous linkage mechanism about its pivot points. | 06-23-2011 |
20110155513 | ELEVATOR DOOR - An elevator door includes a fast panel and one or more successively slower panels, wherein each panel has a front surface, a parallel rear surface and a lagging surface interconnecting the front surface and rear surface. The lagging surface of a successively faster panel is accommodated between the front surface and the rear surface of a successively slower panel when the door is in its fully open position. With this arrangement, the panels can be accommodated one inside the other when the door is in its fully open position and consequently the depth of the telescopic door can be reduced significantly. | 06-30-2011 |
20110266098 | Elevator Hoistway Door Closer - Elevator hoistway door closer device that increases the closing force on the door as the door approaches the door closed position. A elevator hoistway door closer includes a reel having a groove in its side that terminates in a flat edge beyond a breakover angle. The groove may have a first portion of essentially constant diameter and a second portion having a conical helix shape. The third portion includes the breakover angle and may terminate in a flat edge. There may be an elongate tensile element received by the first and second portions and the third portion defined by the breakover angle flat edge, and that has a free end for attachment to a fixed point. There may be a spring for rotating the reel and attracting the elongate tensile element by wrapping the elongate tensile element around the first and second portions of the channel and over the breakover angle and flat edge of the third portion. | 11-03-2011 |
187342000 | Including closure bodily carried along shaft by load support | 1 |
20120205197 | ELEVATOR LIFE SAFETY GATE - A gate below an elevator car which prevents access to an elevator hoistway. The gate slidably mounts behind a toe guard and retracts upwardly if the bottom of the gate encounters a person, object or the floor of the elevator pit during downward travel of the elevator. The gate latches when fully retracted so that it may be out of the way during maintenance. A microswitch is wired into the emergency stop circuit that engages when the gate is latched. A trip wire defining the bottom edge of the gate is also wired into the emergency stop circuit, so that the elevator will stop its downward travel if it encounters an obstruction. Rubber bumpers on the bottom edge of the gate cushion impact to people or objects who happen to be below the elevator car and are struck by the gate during downward elevator movement. | 08-16-2012 |
