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.
Abstract:
The device comprises a driver (11), which is designed for movement from a passive position to an opening position, thus moving the window (5) from a closed to an open position, a spring (27) for actuating the driver (11) in a direction towards the opening position, and a coupling device (10) for retaining the driver (11) in the passive position, which coupling device may be activated and inactivated, and a guide rail system (12, 13) for controlling the movement of the driver (11) from the passive position to the opening position.

Abstract:
A device (1) for vertically driving furniture piece wings (3), characterized in that said device comprises a multiple hoist structure associated with a body of a furniture piece including at least a vertically movable wing (3), said structure comprising a gas spring (4) associated, at a top portion thereof, with a fixed wheel bearing plate (20), integral with a holding body and, at a bottom portion thereof, with a movable wheel bearing plate (16) for entraining a driving cable thereon, said driving cable (21) having an end portion integral with said wing (3) and another portion thereof integral with the fixed wheel bearing plate (20), said fixed and movable wheel hearing plates having each at least two coaxial pulleys for entraining said cable thereon.
Abstract:
Die Erfindung bezieht sich auf einen Türöffner mit einem Antrieb und einem durch den Antrieb angetriebenes, mit der zu öffnenden Tür verbindbaren Kraftübertragungselement, wobei ein zwischen Antrieb und Kraftübertragungselement angeordnetes Verbindungselement vorgesehen ist, das aus einem zueinander beweglich ausgebildeten antriebsseitigen Verbindungskörper und einem türseitigen Verbindungskörper besteht, wobei diese beiden Verbindungskörper bei einem Betrieb des Antriebes miteinander gekoppelt sind zugunsten eines Kraftflusses vom Antrieb zum Kraftübertragungselement, und wobei diese beiden Verbindungskörper von einem Kraftfluß vom Kraftübertragungselement zum Antrieb hin in eine zueinander entkoppelte Position verbringbar sind.
