In an active guide roller and an elevator device according to the present invention, one of an actuator movable portion and an actuator fixed portion includes: a yoke, and a pair of magnets, which are configured to generate a magnetic field intersecting a pivot plane of the guide lever, and another one of the actuator movable portion and the actuator fixed portion includes: a bobbin; and a coil. Contact between the coil and the magnet is avoidable by allowing the bobbin and the magnet to be brought into contact with each other or allowing the bobbin and the yoke to be brought into contact with each other when the actuator movable portion is displaced in a direction perpendicular to the pivot plane.

A passenger/goods conveyor includes at least one transport entity connected with at least one mover, which co-acts together with at least one stator beam defining a movement trajectory for the transport entity. The at least one mover and the stator beam form a linear motor, the stator beam carrying on at least two opposite sides stator faces with stator poles which again co-act with corresponding mover counter faces including mover units facing the stator poles. The mover units are arranged successively in a running direction of the mover, whereby between the two stator faces and the corresponding mover counter faces air gaps are formed, whereby each mover unit includes electro-magnetic components configured to co-act with the stator poles to provide a propulsion force to accelerate and move the mover along the stator beam as well as an attraction force between the stator faces and counter faces to adjust both air gaps. In connection with at least one of the counter faces of the mover, at least one magnetic sensor is positioned facing the stator poles. Thus, the torque angle can always be calculated even after replacement of sensor or drive components.

An elevator is disclosed. The elevator comprises a first upright U-channel guide rail parallel to and opposing a second upright U-channel guide rail. The elevator also comprises a slider with a first side and an opposing second side, wherein a first wheel is attached to the first side and a second wheel is attached to the second side. Some embodiments may comprise additional wheels. The first wheel rolls up and down within the first guide rail, and the second wheel rolls up and down within the second guide rail. A platform extends from the slider. The elevator also comprises a hoist mechanism and a closed loop lifting cable attached to the slider. The hoist mechanism is configured to move the lifting cable and thereby, in cooperation with pulleys, to lift and lower the platform. Preferred embodiments also include a centrifugal brake system and walls and a ceiling on the platform.

A frictionless electronic safety actuator (100) for use in an elevator system, which includes at least one electromagnet (110), and a magnetic plate (120) attached to a connection arrangement (190). The connection arrangement (190) is configured to connect the magnetic plate (120; 220) to a linkage (80) that is actuatable so as to move a safety brake (24) into frictional engagement with an elevator guide rail (20). The at least one electromagnet (110) is operable to selectively produce a magnetic force which acts upon the magnetic plate (120) to displace the magnetic plate (120) and thereby move the connection arrangement (190) to actuate the linkage (80) without the magnetic plate (120) coming into frictional engagement with the elevator guide rail (20).

The invention refers to an electric linear motor comprising at least one linear stator designed to be located in a fixed correlation to an environment, particularly building, and at least one mover designed for connection with an element to be moved and co-acting with the stator, which motor comprises a stator beam supporting said at least one stator, which stator beam has at least one side face carrying ferromagnetic poles of said stator spaced apart by a pitch, and which mover comprises at least one counter-face facing said side face(s) of the stator beam, in which counter-face electro-magnetic components of the mover are located.

A roller guide for guiding a car of an elevator system along a guide rail may include a roller carrier that can be attached to the car and several rollers disposed on the roller carrier. The roller may be configured to roll by their respective running surface on a rolling surface of the guide rail. The rollers may each be mounted movably in the roller carrier with a direction component perpendicular to the rolling surface of the guide rail. The rollers may be mounted in operative connection with one another at least in part by way of hydraulic fluid such that a movement of one of the rollers perpendicular to the rolling surface of the guide rail causes a directionally-opposite movement of at least a second of the rollers. The present disclosure also concerns a car and an elevator system that employ such roller guides.

A roller guide assembly for an elevator device, the roller guide assembly comprising a base member having a mounting means for mounting to the elevator device, the base member comprising a shaft support member; a roller wheel for engaging a guide rail to be rolled on the guide rail; a shaft on which the roller wheel is bearing-mounted, the shaft being straight and non-rotatably supported by the shaft support member, and a vibration dampening element, the vibration dampening element comprising an elastomer body arranged between the shaft and the shaft support member for dampening vibration of the roller wheel and for isolating the vibration from the base member. The shaft is attached to the shaft support member by the vibration dampening element forming a single attachment point for the shaft. The elastomer body is configured to form an elastically spring-loaded universal joint for the attachment of the shaft to provide a universal degree of freedom of an angular movement of the shaft and the roller wheel in relation to the base member.

The invention refers to an electric linear motor comprising a longitudinal stator beam; at least one mover adapted to move along the stator beam; which stator beam comprises at least two side faces located at opposite sides of the stator beam, each of the side faces carrying ferromagnetic poles spaced apart by a pitch, and which mover comprises at least two counter-faces facing the respective side faces of the stator beam, wherein the at least two side faces, as well as the at least two counter-faces facing the respective side faces, are inclined or offset with respect to each other.

An elevator guide having a base attached to an elevator component, a guide riding along a portion of a rail and a spring biasing the guide in contact with the rail. The guide includes one or more of the following: (i) a guide support member operably associated with the guide for movably supporting the guide so that the guide can move toward and away from a corresponding surface of the rail member wherein the guide support member has a plurality of spring engagement sections configured to vary a system effective spring rate; (ii) a roller including a non-metallic rim molded about a bearing; (iii) two independently adjustable stops and, (iv) an opening adjustment member mounted about a notch in the base to vary the distance between the base and the rail. The opening adjustment member has a width and/or depth greater than a width and/or depth of the notch.

An apparatus for displacing an elevator car from its pathway includes a rotational vehicle configured to rotate around an axis of rotation and at least one guide rail section mounted with the rotational vehicle along, which at least one guide rail section the at least one elevator car is arranged to travel. The at least one guide rail section is mounted substantially parallel to the axis of rotation of the rotational vehicle. The rotational vehicle is configured to rotate 90 degrees. An elevator system is also disclosed.
