Abstract: A braking retardation apparatus for doors, windows or the like has a piston pressable into a cylinder against the force of an expelling spring, with the element to be braked acting on the piston rod of said piston. To provide such a braking retardation apparatus with a reduced effort, a grease with high viscosity is applied to the wall of the cylinder.

Abstract: A door closer comprising at the end of one of two pivotally interconnected arms a closing device whose housing encloses a cylindrical piston driven by the arm through a rack-and-pinion system. On each side of this piston a return spring and a bag, filled with an incompressible but deformable viscous gum placed in a hollow piston biased elastically toward the cylindrical piston are placed on each side of the first-mentioned piston. The hollow piston has a diameter distinctly larger than the diameter of the first-mentioned piston, and the combined actions of this difference in diameters and of the viscosity of the gum ensure an effective braking of the return of the first-mentioned piston.

Abstract: This disclosure relates to an electrically actuated door holder and release for the multi-point holding of a pivoted door at selected door opening angles, and for the release of a held door either electrically or in response to manual override. The door holder and release includes a rotatable spindle adapted to be connected to a pivoted door which is either push or pull-side mounted. The holder and release comprises a spindle gear assembly having a pair of male spline gears with each gear having a circular ring of splineways forming a series of male projecting keys. A pair of cams, each having cam lobes defining detent segments with each cam having a circular hole internally grooved to mate with the projecting keys of spline gear, is mounted on the shaft. A pair of springs yieldingly hold the cams into mating positions with associated spline gears to rotate therewith. A double lever having a common pivot or fulcrum carries a roller which follows the cams. The lever may be electromagnetically actuated and released to effect a door hold and release, or alternatively, the lever may be manually overridden. The selected hold-open angles may be set and altered, without removal of the holder and release or the associated door closer from their fixed positions on a header frame and door, respectively. This function is attained by the arrangement of the cams on the spline gears in association with depressible springs which enable the cams to be manually adjusted without removal of any component except the housing cover.

Abstract: A normally pressure-free, failsafe, emergency door closer for use in hospitals, nursing homes or other locations where handicapped persons are housed, comprising an actuating mechanism triggered by a sensing device such as a smoke detector, a spring-loaded arm with a bumper on one end to engage the door and the other end of the arm rotatably attached to the wall adjacent to and above the door and free to rotate in a horizontal plane. The spring-loaded arm is retained in an open position by a vertical pin engaging the horizontal closer arm. The pin is mechanically linked to the armature of an electromagnet opposed by a coil spring. On signal from the sensing device the electromagnet releases the armature and the coil spring urges the pin upwards releasing the closer arm, the end of which engages the door and closes it.

Abstract: A door frame having a head member defining the top of a door opening with the head member optionally supporting an electrically actuated door holder-closer. A module having a frame shell section and a detector for the particulate products of combustion supported on the interior of the frame shell section with access openings being formed in the shell section to enable particulate products of combustion to pass through the shell to the detector. A socket formed in the head member receives the module so that any particulate products of combustion flowing through the door opening pass through the module access openings to actuate the detector. The detector is electrically connected to the door holder-closer to effect closing of an otherwise open door in response to the detection of the products of combustion. The detector may be either an ionization or photocell type detector.

Abstract: A surface-mounted door holder-closer responsive to the particulate products of combustion passing through multiple passageways formed in a holder-closer housing cover, a holdercloser assembly frame, and a dark chamber which is an integral part of a photocell particle detector module. The particle detector module is insertable into the holder-closer frame with the frame and dark chamber walls not only defining the passageways, but also isolating the chamber from spurious light entering the chamber which would render a false alarm or false emergency door release. The frame also houses the principal components of the holder-closer, namely, a closer spring, a dashpot, a latching lever assembly, and an electromagnet responsive to modulated output current flow from the dark chamber to effect alarm or emergency release of the latching lever to close an otherwise open door. The integrated detector-holdercloser is advantageously and simply mounted on the lintel or header of a door frame.
