Abstract: An emergency door closing device that can be installed upon existing doors and hinges to automatically close doors in the response to smoke and fire. The improvements incorporated therein include a hinge cam pivot member that attaches to an existing hinge member of a door and produces a moment force about the existing hinge member allowing a reduced force necessary to pivot the door into a closed position. Further, a novel spring, cam, and lever system is incorporated to activate the moment force to close the door.

Abstract: A hinge arrangement having a first hinge part and having a second hinge part, which are connected to one another such that they can pivot, a first hinge pin being formed on the first hinge part, on which a first hinge sleeve is pivotably mounted, which forms a first sliding bearing with the first hinge pin, a dimensionally stable support part being connected to the first hinge sleeve. A first axial protrusion is formed on a first axial end face of the first hinge pin, which engages in an arcuate first groove of the first hinge sleeve, wherein a circumferential first side wall of the first groove together with the first axial end face and an inner side of an end cover fixed at the end of the first hinge sleeve delimits a working space which is filled with a damping fluid for damping a relative movement of the first axial protrusion with respect to the first groove.

Abstract: A door closer including: a body defining a chamber therein; a piston slidably supported within the chamber, and dividing the chamber into first and second cavities either side of the piston, which in use receive liquid; a biasing device for biasing the piston towards the first cavity; a passageway connecting the first cavity to the second cavity for permitting the flow of fluid therebetween; a blocking member for controlling the flow of liquid through the passageway between the cavities; a moveable member moveable between first and second positions, wherein when the moveable member is in its first position the moveable member causes or permits the blocking member to assume a blocking position, thus preventing or at least inhibiting the flow of liquid from the first to the second cavity, and wherein when the moveable member is in its second position the moveable member causes or permits the blocking member to assume a non-blocking position, thus permitting the flow of liquid from the first to the second cavity; and a permanent magnet positioned adjacent or close to the moveable member for holding the moveable member in its first position; wherein the door closer includes a pole switching device that can produce a magnetic field that is in opposition to the magnetic field of the permanent magnet to effectively cancel out or overcome the magnetic field of the permanent magnet and produce a net magnetic field that is either zero or in the opposite direction to the magnetic field of the permanent magnet so as to effect movement of the moveable member between its first and second positions.

Abstract: An apparatus for adjusting the force in a door operator or closer comprises an elongated housing and a spring therein connected to the door operator or closer. A spring collar is non-rotatable about the longitudinal axis of the housing and adapted to move linearly within the housing. A fixed adjusting screw extends along a longitudinal axis of the housing and the spring collar is slidable linearly along an outer surface of the adjusting screw. A nut is threadably engaged at a distal end of the adjusting screw and is rotatable about the longitudinal axis of the screw, the nut bearing on the spring collar during rotation. The spring collar bears on a distal end of the spring to vary the spring compression and thereby vary force applied by the door operator or closer. The housing has an opening in a sidewall through which the spring is visible, and the housing exterior surface includes markings indicating the degree of spring compression. An indicator is moveable along and visible from the exterior of the housing to indicate the compression of the spring.
