Guide assemblies are provided which include a translation guide, a door leaf for a lift, movable along the guide and comprising at least one support element placed at one end of the door leaf, at least one runner housed slidably in the translation guide and defining one or more connection seats to the support element, wherein the connection seat/s and the support element can be coupled with at least two different orientations of the runner with respect to the door leaf. For each orientation, the runner delimits at least a different friction surface with respect to the translation guide, the friction surfaces being non-equidistant from the support element so that the relative position between the door leaf and the translation guide can be changed by different orientations of the runner. The invention further relates to runners usable in a guide assembly.

A landing floor door access system for an elevator system includes a door lock operably connected to a landing floor door, and a door lock controller operably connected to the door lock. The door lock controller is configured for non-contact communication with an access device such that communication between the access device and the door lock controller initiates a signal from the door lock controller to the door lock to deactivate the door lock. A method of accessing a hoistway of an elevator system, includes approaching a landing floor door of the elevator system, the landing floor door positioned at the hoistway, and initiating communication between an access device and a door lock of the landing floor door via non-contact interaction between the access device and the door lock. The door lock is deactivated via the non-contact interaction between the access device and the door lock.

A permanent magnet linear motor. The permanent magnet linear motor including a primary comprising a magnetically permeable core having a first face surface on a first side of the core a plurality of teeth forming a plurality of slots on the first side, and a plurality of multi-phase windings wound to have segments thereof in the slots forming a plurality of magnetic poles at each of the first face surfaces; a permanent magnet pair of opposing polarity configured to produce magnetic flux and cause the primary to exert a force on the secondary when the plurality of multiphase windings are excited by a multiphase source; and a passive ferromagnetic secondary adjacent to but spaced from the first face surface, the passive ferromagnetic secondary being moveable with respect to the primary.

A fire-rated sliding elevator glass door is provided. The door includes a face panel, a liner, a fire-rated glass panel, and a retainer that retains the glass panel in the door frame. The elevator door is configured to pass a 90-minute fire rating test. The elevator door can be implemented as a single-speed side open elevator door, a single-speed center open elevator door, a two-speed side opening sliding elevator door, or a two-speed center opening sliding elevator door. A method of constructing the fire-rated elevator door is provided.

A device for unlocking a landing door includes a door leaf that can be moved between an open position and a closed position, a bar arranged on the door leaf to lock the door leaf in the closed position, and an energy accumulator coupled to the door leaf to provide the energy for moving the door leaf into the closed position in the event that the energy supply needed to drive the door leaf fails. The energy accumulator is coupled to the door leaf by an elastic element such that through a displacement of the energy accumulator when the door leaf is in the closed position, the bar is moved to an unlocked position.

A sill (1, 1) for a lift door is manufactured with a method that includes the steps of providing at least one support element (2) and an upper profile (4) that defines at least a boundary surface (6) of a first groove longitudinal (8) for slidingly receiving a lift door. The support element (2) and the upper profile (4) are joined, placing a first demarcation profile (10, 10) alongside the upper profile (4), so that a boundary surface (12) of the first demarcation profile delimits part of the first longitudinal groove (8). A sliding transversal cross-section of the first longitudinal groove (8) is adjusted by approaching/distancing the boundary surfaces (6, 12) and, having obtained a desired sliding transversal cross-section, constraining the mutual position of the first demarcation profile (10, 10) and of the upper profile (4).

A light grid for mounting on an elevator car door for object detection and for determining periodic door movements, including transmitter elements that emits radiation with a specific intensity, receiver elements for receiving the radiation from an assigned transmitter element, and a control device for evaluating the receiver elements in regard to interruption of the radiation coming from an assigned transmitter element and for outputting a signal for object recognition upon interruption. At least one receiver element is configured to output an intensity value for the received radiation. The control device evaluates the intensity value and distinguishes separate high, medium and low intensity value ranges with high, medium and low intensity values, and performs an alternation phase with at least one alternating from the low via the medium to the low intensity value range and to output a signal in the event of an alternation phase having been recognized.

A fire-rated sliding elevator glass door is provided. The door includes a face panel, a liner, a fire-rated glass panel, and a retainer that retains the glass panel in the door frame. The elevator door is configured to pass a 90-minute fire rating test. The elevator door can be implemented as a single-speed side open elevator door, a single-speed center open elevator door, a two-speed side opening sliding elevator door, or a two-speed center opening sliding elevator door. A method of constructing the fire-rated elevator door is provided.

A pressure sensitive mat is provided. The pressure sensitive mat includes a nanocomposite film, a first conductive foil, an oxide layer interposed between a first side of the nanocomposite film and the first conductive foil, a second conductive foil and a nanotube film interposed between a second side of the nanocomposite film, which is opposite the first side, and the second conductive foil.

A zone object detection system including a passenger compartment. Also included is a door moveable between an opened position and a closed position. Further included is a first sensor monitoring a first zone outside of a plane of the door. Yet further included is a second sensor monitoring a second zone comprising at least one of the plane of the door and outside of the plane of the door. Also included is a controller in operative communication with the first sensor and the second sensor, the controller commanding a first modification of a door closing movement of the door if an object is detected in the first zone, the controller commanding a second modification of the door closing movement of the door if an object is detected in the second zone.
