Abstract: A method and device for safety braking an elevator having an upright guide rail wherein the device includes a housing having braking elements on both sides of and being movable along the guide rail, a safety restraint on both sides between the housing and the braking elements, and a clampable and lockable actuating device that unlocks and unclamps in response to a triggering event and brings the braking elements into braking engagement with the guide rail. The actuating device, when unclamped, develops a feed force and movement transverse to the guide rail longitudinal axis engaging the braking elements with the guide rail from a laterally distanced initial position, wherein the braking elements are entrained by frictional contact on the guide rail and enter the safety restraint, and wherein the actuating device is moved back into the initial position, clamped and locked by the braking elements located in the safety restraint.

Abstract: A system for determining a position of a user in a building includes a control device, a plurality of stationary radio signal transmission devices, a radio signal receiving device, and a signal processing device. The signal processing device determines primary channel impulse responses based on the radio signals received by the receiving device. The signal processing device also determines a secondary channel impulse response based on a secondary radio signal received by the receiving device from a mobile device of a user. The channel impulse responses are evaluated to determine degrees of similarity that indicate how similar a first primary channel impulse response and the secondary channel impulse response are to one another. For each degree of similarity, a distance of the mobile device from the transmission device corresponding to the degree of similarity is determined. A position of the mobile device is determined based on the distances.

Abstract: A safety brake includes a first brake element, a first guide element, and an actuating element. The first brake element is mounted in a displaceable manner in a linear bearing on the first guide element. The first guide element can be moved between a rest position and a braking initial position. The actuating element is designed to move the first guide element from the rest position into the braking initial position, more particularly to activate the safety brake. The first brake element can carry out a braking movement from the braking initial position into a braking position. The braking movement returns the first guide element to the rest position. The first guide element is guided on a first parallelogram guide.

The system can include a stationary access region, a transport belt made up of a plurality of tread units, a transition region in which combing structures of the transport belt adjoin static comb structures of the access region, and an illuminating device having at least one light source for emitting light in the visible spectrum. The illuminating device can be configured such that at least a first portion of the light emitted is focused to predominantly illuminate an elongate transition surface which includes the transition region.

Abstract: An elevator system includes a car and/or a counterweight connected to a belt having a plurality of ribs. The elevator system further has at least two deflecting elements over which the belt is guided and which each have a plurality of grooves. The grooves of at least one of the deflecting elements are configured with geometries that differ from the grooves of another of the deflecting elements. The belt has longitudinal ribs that cooperate with the grooves.

Abstract: A yoke assembly for suspending an elevator car or a counterweight in a shaft of an elevator has a yoke adapted to be mechanically coupled to the elevator car or the counterweight. The yoke has a height with respect to a height axis and a length with respect to a longitudinal axis orthogonal to the height axis; a pulley for suspending the yoke, wherein the pulley has a diameter equal to or less than the height of the yoke and is attached to the yoke so as to be rotatable about an axis of rotation whose position with respect to the height axis is such that the pulley does not protrude beyond the yoke in either direction of the height axis; wherein, when the yoke is suspended in the shaft, the height axis is a vertical axis and the axis of rotation is a horizontal axis.

Abstract: A counterweight for an elevator system has an asymmetrical cross section in a horizontal sectional plane. The asymmetrical cross section results in an improved connection of the counterweight to a guide rail, a reduction in a number of components, in particular guide rails, for the elevator system, and a reduction in an installation space for the elevator system thereby simplifying installation of the elevator system.

Abstract: An elevator system includes an elevator car movable in an elevator shaft, a suspension means extending in the elevator shaft, a drive machine associated with the suspension means and a controllable coupling device arranged on the elevator car. The suspension means has a coupling element that the coupling device can be coupled to and uncoupled from, as a result of which a drive connection between the elevator car and the suspension means can be established and released. The elevator system has a guide system guiding the coupling element during a movement in the elevator shaft. The guide system has a guide that is stationary relative to the elevator shaft and a runner that is connected to the coupling element via a connection and is guided along the guide. The connection between the coupling element and the runner enables a relative movement between the runner and coupling element.

The retaining units are connected to the traveling body such that each of the retaining units and the traveling body can be slid relative to each other within a limited sliding displacement. A first sliding displacement of a first of the retaining units is longer than a second sliding displacement of a second of the retaining units.

Each of the guide elements is fixedly attached to an upper holding point and a lower holding point in the elevator shaft and is tensioned between the upper holding point and the lower holding point. The measuring platform has guide apparatuses that laterally support the measuring platform on the guide elements and guide the measuring platform parallel to the guide elements during a displacement movement in a displacement direction. The measuring platform has a distance measuring apparatus to measure lateral distances to the lateral walls of the elevator shaft. The lifting apparatus moves the measuring platform in the displacement direction.
