A door closer assembly for an entryway device having a position sensor that assists in determining the location of the door closer assembly, and thus the location of the associated entryway device, relative to at least an entryway. The position sensor can be coupled to, and/or part of, the door closer assembly. Information obtained by the position sensor may be used by one or processing devices of an access control system to determine whether the door closer assembly and/or the entryway device is at the closed location, among other locations, as well as the direction(s) of displacement of the entryway device. Such information may be utilized in calibrating other devices, as well as determining the occurrence of a number of events, including unauthorized displacement or holding of the entryway device. A timer may also be utilized to further evaluate the nature of the displacement of the entryway device.

A door closer system having a door closer that includes at least one sensor configured to sense an operating characteristic or condition relating to the door closer including a position or speed of displacement of at least a portion of the door closer or an associated entryway device. The sensor(s) can also provide information relating to the performance or condition of one or more components of the door closer, such as the operation of a backcheck mechanism, as well as tracking the number of door cycles. Information obtained by the sensor(s) of the door closer system can be communicated to a lockset device of an entryway control system. The lockset device can be configured to communicate information received from the door closer system to an access control system, which can in turn provide the communicated information to a management system.

A device for at least partially automatically actuating a door leaf, includes a drive having a drive axis of rotation for driving the door leaf at least partially during a movement between an opening position and a closing position, a casing element having a casing axis of rotation for assisting a movement of the door leaf, lever kinematics having at least one lever arm for establishing an operative connection between the drive and the casing element. The lever arm includes a drive-sided connection section, which is supported to be rotationally movable around the drive axis of rotation. The lever kinematics includes at least one transmission component for transferring electric energy and/or data between at least one casing-sided energy source and a drive-sided energy recipient. The connection section has a cranked course, wherein a multi-layered functional compartment for mechanically connecting the lever arm and for electrically connecting the transmission component to the drive is configured along the cranked course of the connection section.

The present disclosure describes various embodiments of a concealed or hidden door closer that is installed in a rail of a door assembly. In some embodiments, the door frame and door closer components are configured to allow the door assembly to be readily installed as either a left or a right hand hinged door.

A drive device for moving a leaf, in particular a door leaf or a window leaf, with an electric machine including an, in particular single, stator and an, in particular single, rotor, which can be rotated about a machine axis, and with a gear coupled to the electric machine. The gear has a first gear element, which can be rotated coaxially with the machine axis, with the first gear element being connected to the rotor in a rotationally-fixed manner.

A system for fixing and/or emergency opening of a leaf of a door, a window or other closure comprises a drive having at least one mechanical energy storage device, at least one electric motor having a motor shaft operatively connected to the leaf, and control electronics for controlling the electric motor. The electric motor can be actuated by the control electronics both for damping of the leaf movements and for fixing of the leaf against a force of the mechanical storage device and/or for electric motor-driven emergency opening of the leaf.

The aim of the invention is to achieve a door closer arrangement (1) where the force needed for opening the door (2) is not so substantial. The invention comprises a door closer (6), a slide rail (7), and an arm (8) that connects the door closer with the slide rail. The arrangement comprises also a second rail (9), which is arranged to form a slide slope for the door closer (6).

An automatic door operator operating on standard 120V/240V AC power utilizes a servomotor for operation, and thus no separate transformer is required for the operator. The servomotor incorporates programming to limit torque, and thus no slip clutch is required in order to allow manual operation of the door. Furthermore, because the servomotor has built-in control logic, no separate digital control logic is required. Because the position of the servomotor is continuously maintained, the relative position of the door with respect to a fully opened or fully closed position is always known, and no separate external signal is required in order to monitor the door position.

A guiding rail for guiding a door leaf between an opening position and a closing position in relation to a door opening in a wall includes: at least one guiding section with a guiding compartment, in which a sliding element is accommodated to be movable, wherein the guiding section includes a guiding opening, through which a bearing axis of the sliding element exits at least partially from the guiding compartment, at which axis a lever element is supportable to be rotationally movable, in order to establish an operative connection between the sliding element and the door leaf. The guiding rail further includes at least one functional section with a functional compartment, in which a transmission means is receivable, which serves for transferring electrical energy and/or data between at least a wall-sided energy source and a door leaf-sided energy recipient and a labyrinth guide between the guiding and functional compartments.
