Abstract: A progressive safety device for an elevator includes a brake unit and an actuating unit. The brake unit has a first brake shoe with first spring assemblies and a triangular rotatable support with second and third brake shoes. The actuating unit has an electromagnetic actuator with a locking bolt, a guide bolt with a coaxial compression spring and an actuating arm. On actuation, the compression spring moves the actuating arm against a guide rail whereby grooves on the actuating arm create a frictional engagement with the guide rail turning the actuating arm about a swivel bearing and through a follower turning the support. With the turning motion and the engagement of one of the second and third brake shoes with the guide rail, the first brake shoe is guided against the guide rail and generates the necessary braking force on the guide rail.
Abstract: A wheel for driving a flexible handrail of an escalator or moving walk. The wheel has a power transmission element that can be turned about an axis of rotation and that has, on its circumference a contact surface through which an outwardly acting radial force can be exerted. The wheel also has two base sheaves that are arranged coaxially to the power transmission element. Each base sheave has a plurality of slits that are arranged in the outer edge area of the base sheave and extend toward the axis of rotation. The slits of one base sheave form, with the slits of the other base sheave, slit pairs. The wheel has a circumferential cover with an inside surface against which the contact surface of the power transmission element rests. A plurality of pins is arranged in the circumferential cover, each pin engaging a separate respective slit pair.
Abstract: The invention concerns a control and/or monitoring device comprising pairs (P, P?) of interactive members (1, 2; 1?, 2?) each of which includes an electronic label (1, 1?) identified by a specific identification code (KID1, KID1?) communicating with said label (1, 1?). For each pair (P) of interactive members, the inventive device also comprises a state encoder at least partially borne by the label (1), said encoder producing a state signal which is accessible to the reader (2) and representing a logic or analog state affecting the label (1) or a relationship between the label (1) and the reader (2).
Abstract: A cable brake has an electromagnet releasably retaining a mass that falls down guide rods under the effect of gravity and impacts a first arm of a trigger lever. Upon impact by the mass, the trigger lever rotates a second arm with a pawl to release a crossbar, whereupon pressure springs press a moveable brake plate against a cable strand to halt the cable strand. A return mechanism utilizes a screw and cooperating nut or a coupler to return the moveable brake plate and pre-stress the pressure springs.

Abstract: A device provides an elevator installation with a shortened car travel path to establish a temporary protective space below and/or above the car upon activation of the car safety brake device. The speed limiter cable is limited, independently of the speed limiter, in a travel path by a switchable stop device. This limitation causes an actuation of the car safety brake device in the corresponding travel direction.
Abstract: A method and apparatus for mucosal biopsy including a stationary base clevis component, upon which an open frame jaw is actuated rotationally to engage tissue and retract samples. A rack and pinion mechanism drives the jaw motion, which can be controlled axially by the physician. A metal retriever component captures tissue from the open frame jaw, and advances the samples proximally into the collection chamber, where they are maintained as the retriever is returned to its most distal position. Furthermore, the open frame design employs a reliable and compact means for actuation that can be decoupled from sample transfer and storage functions.
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: A method, a system and a computer program product presents multimedia contents in elevator installations. At least one individual user profile with multimedia contents is stored for each elevator user. When a user is identified, the multimedia contents in the associated user profile are presented. Dining a group transport, the individual user profiles associated with the users in the group are linked in a collective travelling profile for presentation of selected multimedia contents.
Abstract: An escalator has steps has steps that have a step-tread surface with a step-tread edge. Step brushes are arranged on the step-tread edge perpendicularly or vertically. Step brushes may also be arranged on the edge of the step's step-riser edge. The brushes provide a barrier against the entry of objects into the gap between a moving step and the stationery skirt-panel of the escalator.
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: A multi-stage elevator car has equipment for fine positioning of the cars wherein the car thresholds are positionable at the level of the floor thresholds. The fine positioning adjusting equipment operates on the principle of a double lever and moves a car frame along a path (?z).

Abstract: A deflecting module has deflecting elements that are displaceable relative to one another. The deflecting elements are mutually supported, wherein at each side the outermost deflecting element is carried by a bearing plate. Each deflecting element has a housing which carries an axle and, for the mutual displaceability, has on one side a groove and on the other side a cog. A deflecting roller is rotatably arranged on the axle for guiding and deflecting elevator car and counterweight support elements, for example a flat belt, and producing a change of direction of the support elements.
Abstract: An elevator, particularly for transporting passengers, has an elevator car guided in an elevator shaft a direct drive motor. The drive motor includes an active primary part at the elevator car and a passive secondary part that is fixed in the elevator shaft and is spaced from the primary part by an air gap. In order to achieve a high power capability, the drive motor is configured as a transverse flux motor that moves the primary part linearly relative to the secondary part under the influence of an electromagnetic propulsive force. The secondary part has at least one rail made of a soft magnetic material and subdivided into a plurality of segments having a predetermined length. The segments are fixed to a wall of the elevator shaft by intermediate elements.

Abstract: The invention provides an elevator having a car movable along guide rails mounted in a shaft. The elevator comprises an inspection control station mounted on top of the car and accessible via a movable control station cover, blocking means for selectively preventing movement of the car into a safety space within the shaft and actuation means for actuating the blocking means. The actuation means is configured for concurrent movement with the control station cover. Accordingly, a temporary safety space is automatically created within the shaft as the maintenance technician opens the control station cover to move the car using the inspection control station.
Abstract: A guide device guides a load carrier of an elevator installation along a guide surface and comprises a guide element contacting the guide surface and connected by a connecting element with the load carrier such that the guide element is movable relative to the load carrier in a first and/or a second positional range. The connecting element comprises first and second resilient elements in a serial arrangement, wherein movement of the guide element in the first range deforms both resilient elements and movement of the guide element in the second range exclusively deforms the second resilient element. The overall stiffness of the connecting element is a function of the respective position of the guide element. Stiffness of the second resilient element increases during compression in the second range, wherein the overall stiffness is substantially constant at a transition between the first and the second ranges.
Abstract: A clutch couples a car door of an elevator car with a landing door of an elevator system, wherein the car door is movable with respect to the elevator car by a first actuator. The clutch includes at least one coupling element and a second actuator. The coupling element is movable with respect to the car door between a first position and a second position by the second actuator such that the coupling element engages with the landing door when the elevator car is within a landing zone and the coupling element is moved towards the second position, thereby establishing the coupling of the car door with the landing door. The second actuator is a linear motor.
Abstract: A wheel for driving a flexible handrail of an escalator or moving walk turns about an axis of rotation, and has a tire with a tire cover that may be filled with pressurized gas and a contact surface that is intended to rest against the handrail. The contact surface is formed on a power transmission element that has a reinforcing insert and is accommodated in a peripheral recess of the tire cover.
Abstract: An apparatus for moving elevator equipment, particularly an elevator car when stuck in a shaft, comprises a suspension point which is connected to the elevator equipment by an adjustable-height connection. Contrary to the prior art, the suspension point includes a length-adjustable assembly configured for engagement with opposing walls of the shaft or opposing guide rails within the shaft at any chosen location along the shaft. The invention thus provides a localized solution that can be used conveniently at any position within the shaft and is therefore independent of the position, and indeed the presence, of any lifting hooks within the shaft.
