    Abstract: A double glazing arrangement has at least one pane mounted between two opposed vertical channels and arranged for both vertical sliding movement within the confines of the channels without the provision of a counterbalancing system and movement in at least one lateral direction for removal of the pane without any initial dismantling of the arrangement. Releasable catches are provided which are for both holding the pane in a plurality of raised positions and preventing lateral movement of the pane. The arrangement is particularly advantageous for a pane of transparent acrylic material.

    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: The present invention relates to a door operator device and sectional overhead door system with anti-pressure and anti-theft functions, principally having a small-tooth-difference reduction gear and a ratchet-locking device. An input end of the small-tooth-difference reduction gear is kinematically connected to an input shaft; an output end of the small-tooth-difference reduction gear is kinematically connected to a shaft; the small-tooth-difference reduction gear includes a ratchet on its outer circumference; the ratchet-locking device is controlled to selectively lock or unlock the ratchet. When the ratchet-locking device locks the ratchet, it can realize the anti-theft function; when the ratchet-locking device unlocks the ratchet, and the shaft is driven by the input shaft through the small-tooth-difference reduction gear, but the shaft decelerates, stops, or even reverses due to an obstacle encountered or other factors, the input shaft and the small-tooth-difference reduction gear will idle automatically.

    Abstract: The electric strike can have a housing having an internal face receivable against a receiving face of a door frame, an external strike face, a socket recessed into the strike face along a socket axis normal to the receiving face of the door frame, for receiving a male locking member retractably mounted to a door, the male locking member also being moveable transversally to the socket axis, along a horizontal escape path, by opening the door, the electric strike further having a keeper pivotally mounted around a pivot axis between a closed configuration and an open configuration, the pivot axis parallel to the socket axis and offset from the escape path on a first side of the socket, inside the housing, the keeper having a gate member forming a restraining wall of the socket blocking the escape path when in the closed configuration, and a distal end.

    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.
