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 assembly includes a door closer without a powered drive for closing a door. The door closer includes an energy accumulator, wherein the energy accumulator is chargeable by manually opening the door and wherein the energy accumulator discharges for closing the door. A sensor unit is also included for detecting an angle information with regard to the opening angle of the door.

A combination door operator assembly and door, wherein the door operator assembly includes an operator unit mounted to the door on the pulling side or the pushing side thereof, an arm linkage having a driving arm and a driven arm, a mounting bracket preferably mounted on the frame to which the door is hinged, a rechargeable power storage pack having at least one of a rechargeable battery and one or more capacitors, and a controller, for monitoring a speed and a position of the door, wherein when the door moves faster than a predetermined speed, the motor is used as a generator to charge the rechargeable power storage pack and the speed of the door is reduced.

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.

A hinge device for a rotary door is mounted to a door that is rotating to open and close the door while being rotated in various manners. The hinge device can be rotated in a free stop type in a predetermined section after it is rotated by an external force, and is automatically reversely rotated in a section in which it is reversely rotated after the free stop rotation.

An exemplary door control assembly includes a door control and an armature assembly. The door control includes a body and a pinion rotatably mounted to the body for rotation about a rotational axis. The pinion has a radially-outer periphery and a recess is formed in the radially-outer periphery. The armature assembly comprises an armature and a coupler. The armature is rotationally coupled with the pinion, and includes an opening in which the pinion is received. The coupler is movably mounted to the armature for movement between a coupling position and a decoupling position. With the coupler in the coupling position, the coupler projects into the recess and axially couples the armature and the pinion to prevent removal of the armature from the pinion. With the coupler in the decoupling position, the coupler axially decouples the armature and the pinion to permit removal of the armature from the pinion.

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.

An exemplary armature assembly is configured for use with a door control mounted to one of a door or a doorframe. The door control includes a rotatable pinion, and the armature assembly includes an armature, a shoe, and an elastic component. The armature has a first end and an opposite second end, and the first end includes an opening sized and shaped to receive the pinion at a first interface. The shoe is configured for mounting to the other of the door or the doorframe, and the second end of the armature is pivotally connected to the shoe at a second interface. In certain forms, the elastic component coupled with the armature and configured to absorb mechanical shocks at one of the first interface or the second interface. In certain forms, the elastic component is configured to absorb mechanical shocks along the length of the armature.

The invention comprises a door closer (1), a slide rail (3) and an arm (2). The arm is connected to the door closer (1) and to the slide rail (3). The slide rail is provided with a hold open device (4) in order to keep a door open. The arm (2) comprises an outer arm (8A, 9A) and an inner arm (8B, 9B). The inner is situated partly inside the outer arm in a sliding manner. The arm (2) also comprises a spring arrangement (11) in order to hold the inner arm (8B, 9B) in a normal position in the outer arm (8A, 9A), and a release device (10A, 10B). The release device is arranged to release the inner arm (8B, 9B) from its normal position when an external force being strong enough to active a release of the release device (10A, 10B) drives the inner arm (8B, 9B) out from the outer arm (8A, 9A).
