Abstract:
A system (1) is disclosed for detecting and signalling in air a failure of balancing systems for closing members comprising at least one local system (3) for detecting a failure of at least one of the balancing systems, equipped with means for transmitting in air at least one failure signal (4) representing the failure of the balancing system; and at least one remote system (5) for receiving the failure signals (4) equipped with means for displaying an alarm indication of such balancing system failure. A remote signalling process which uses the system (1) is further disclosed.
Abstract:
A door (10) positioning mechanism (12) with a movable carriage (40) driven by a motor (28) through a lead screw (42), wherein the movable carriage (40) is connected to open and close the door (10) by movement of the door (10) rectilinearly along a track (14) through the expedient of a drive train utilizing a multiple sheave and cable connection between the door (10) and the movable carriage (40). A hand disconnect (32) is provided to disable the positioning mechanism (12) and allow manual movement of the door (10). A thermal (fire switch) dead weight control (38) is also provided to override the positioning mechanism (12) and automatically shut the door (10).
Abstract:
PURPOSE: An actuating device is provided to easily apply to other door size or door weight without exchanging elements, to enable the control of door operating way. CONSTITUTION: An actuating device is composed of: a flap(110) of a door guided in a moving way at a guide unit(120) equipped at a side panel(118) by a guide member(116) having a roller(112,114); a cable(122) fixed at the guide member(116) going from the end of fixed return pulley(124) and a rocking lever(128) through a pulley(126) supported to a supporting parts(130); a gear established to control the length of the cable; other end of the rocking lever(128) pivoted along the rim of a bolt(138) in a rotary type; a groove(181,182) and a bore hole(183) at the rear recess.
Abstract:
The invention relates to an actuating device for a closing element movable in a vertical direction within openings which are guided in lateral guides, with the door weight being taken up by a spring-loaded tension element or being compensated by a counterweight.
Abstract:
A drive device for a wing of a door, window or the like, comprises a drive member for driving the wing. The drive member is rotatable about a rotation axis between two positions which corresponds to two positions of the wing. A drive motor is connected to the drive member for driving the drive member from the first position to the second position. A spring device is connected to the drive member for driving the drive member from the second position to the first position. The spring device comprises a spring means which is arranged between a stop and a spring seat. The stop has a fixed position relative to the rotation axis of the drive member. The spring seat is arranged on a slidable body so as to move the spring seat relative to the stop. A flexible connecting element is attached to the drive member and to the slidable body of the spring device for allowing a displacement of the slidable body along the elongate guide member so as to prestress the spring means when the drive member is driven from the first position to the second position. The flexible connecting element is arranged adjacent to and outside of the spring means and extends from the drive member substantially parallel with respect to the longitudinal axis of the spring means, is guided over a reversing guide member of the slidable body, and from there extends in a direction opposite to the first part.
Abstract:
Die Erfindung betrifft eine Betätigungsvorrichtung für ein in vertikaler Richtung verschiebliches Verschlußelement (10) für Öffnungen aller Art, vorzugweise Möbel, z.B. Schränke, die in seitlichen Führungen (20) geführt sind, wobei das Türgewicht durch ein federbelastetes Zugelement (22) aufgenommen oder über ein Gegenwicht ausgeglichen wird.
Abstract:
A door has a door leaf (10) which can be moved overhead between a closed and an open position and a weight-balancing device connected at one end to the door leaf and fixed at the other end. The weight-balancing device has one or several helical spring units space-savingly designed in such a way that the helical spring unit or units (16) are made of at least two driven helical springs loaded in parallel, of which the inner one has a helix with an outer diameter which is smaller than the inner diameter of the helix of the outer spring. The helical springs are coaxially arranged or nested one inside the other. Seen in the same longitudinal axial direction, one spring is wound clockwise and the adjacent spring is wound anti-clockwise, so that the helices of adjacent springs cross each other.

Abstract:
A door has a door leaf (10) which may be moved overhead between an open and closed position and which is connected by means of a traction cable system to a weight-balancing device, driving motor or another similar power source. The traction cable system has at least one cable unit (21) secured at one end to the door leaf and fixed at the other end. In order to dispense with catching means and ensure a longer service life, at least one of the cable units (21) has two cables (21', 21'') loaded approximately in parallel and combined by their associated ends each to a building element. At least one of said building elements is designed as a cable tension compensating device.
