Abstract: An elevator door system includes a motor rotating a vertical reel, and an elevator door. The door can be formed of a plurality of vertically aligned rigid panels or can be a sheet of material which is rigid or reinforced in the vertical direction or can have any other appropriate form making it suitable for being wound upon and unwound from the reel. The door is mounted to a flexible force transmission member provided along an entire width of the door and interconnected to the reel. Accordingly, the forces generated by the motor for opening and closing the door are substantially transmitted through the transmission member rather than being imparted onto the door itself Hence, in use the strain on the door is greatly reduced and therefore the quantity of material used for the door and consequently its cost and mass can be reduced without deteriorating performance.

Abstract: An elevator door system includes a motor, a vertical reel, and a door attached at a first end to the vertical reel for winding and unwinding thereupon. A force transmission device interconnects a second end of the door and a compensation device whereby the motor simultaneously drives the vertical reel and the compensation device having a variable diameter. In use, as the door is unwound from the vertical reel, the force transmission device is simultaneously wound upon the compensation device. Hence, not only is a thrust exerted on the door by the vertical reel, but a drag is exerted thereupon by the force transmission device. Furthermore, the compensation device has a variable diameter to compensate for, amongst other things, the changes in the diameter the door wound on the vertical reel. Hence, the tension in the force transmission device and the door can be kept substantially constant during operation.

Abstract: A door system includes a reel, a door interconnect at a first end to the reel for winding and unwinding thereupon and one or more guide channels. The reel is rotatably mounted on a lever which is pivotally mounted to a pivot axis. Thus, the reel can pivot about the pivot axis to ensure that, during operation, a point at which an outer layer of the door engages/disengages with the penultimate door layer remains in the same general location with respect to the guide channels and accordingly, an angle (if any) at which the door enters the guide channels remains constant throughout operation of the door system.

Also, the power transmission and the suspension member or respectively hoisting member are physically separated from each other. The power transmission and the suspension member or respectively hoisting member are stretched against at least one supporting body.

Abstract: A device moves a door seal for a displaceable door panel of an elevator car in an elevator installation with an elevator shaft having shaft doors. The movable door seal is arranged so that the door panel in a closed state is sealed off. The device includes an entrainer unit connected with the door panel and upon stopping of the elevator car at a floor executes a part movement. The device also includes a coupling mechanism mechanically connecting the entrainer unit with the door seal to bring the door seal out of a sealing position into an open position when the entrainer unit executes the part movement.

Abstract: An elevator installation has a sealing element that is movable by an electromagnetic actuator from a first position to a second position. The sealing element includes a seal carrier that is movably arranged at a door leaf of a door of the elevator installation. An electromagnetic actuator is fastened in the region of the door and upon actuation acts on the seal carrier to move it from the first position to the second position. An electrical circuit triggers the actuation before the door leaf executes an opening movement.

Abstract: An elevator having deflecting rollers integrated in the cage floor or in the counterweight. The support and drive element is guided in the cage floor through a floor channel. By comparison with a conventional cage floor with deflecting rollers (bottom blocks) arranged underneath the cage floor, the cage floor is constructed to be very small in height overall, which has a direct effect on the shaft pit depth. The height gained by the cage floor can be saved in the shaft pit depth.

Abstract: Method and device for stopping of an elevator cage due to a deviation of the elevator position, acceleration, or speed from a travel curve in excess of a certain predetermined safety margin. Travel parameters, computed by the elevator control, may be passed on to a drive control of a cage drive for moving and positioning of the elevator cage, and may also be passed on to a drive control of a reference drive for moving and positioning a trigger part. Accordingly, each of the elevator cage and the trigger part may be driven by individual discrete drivers, but, due to each driver receiving the same travel parameters, the elevator cage and the trigger part move in synchronization. The trigger part may be coupled to the elevator cage to be movable when the elevator cage deviates from the computed travel curve. When the deviation from the travel curve exceeds a predetermined safety margin, the trigger part may actuate a safety switch to stop the cage or reference drivers or to arrest movement of the elevator cage.

Abstract: A roller for use in a roller guide for sliding elevator doors may include a resilient element for effecting quieter elevator operation. The resilient element may form a roller body with a bowl shaped annular casing of sheet steel to run along a carrier section including a preferably greased rail running surface. The roller body may be dimensioned such that the spring effect of the resilient element is stressed only within the elastic range or limit of the sheet steel. To obtain optimum spring effect, a radius of the rail running surface may be slightly greater than a radius of the roller body. Also, the roller body may include an open side.

Abstract: A roller guide for use with sliding elevator doors may include elements for effecting quieter sliding door running by reducing noise associated with the rollers running along the roller guide. The roller guide may by formed by a convex running surface made from a hose-like covering of sheet metal producing a spring effect. The hose-like covering may be dimensioned to utilize the spring effect within an elastic range or limit of the sheet metal, with the optimum spring effect occurring when a radius of the rail running surface is slightly less than a radius of a running surface. An elastic material, to dampen running noise, may be inserted between the hose-like covering and a carrier section. The carrier section may also include spaces for clamping respective ends of the hose-like covering.

Abstract: A door safety circuit for monitoring of story doors in lift installations. The door safety circuit includes a transmitter that produces a non-electrical signal which is guided by a series of conductor portions. The non-electrical signal may be transmitted through a first conductor partial portion to a latching device of a first story door, depending upon the latched state of the first story door, the signal may be either transmitted to a second conductor partial portion, which may be included within the latching device, or no longer transmitted. If the signal is similarly transmitted through a plurality of conductor partial portions and serially connected story door latching devices, the circuit may indicate that each story door is properly latched. The circuit may also include a plurality of sensors coupled to a failure recognition circuit for monitoring each conductor partial portion.
