Abstract:
Die Erfindung betrifft eine Vorrichtung zum Schwenken drehbar gelagerter Flügelelemente, insbesondere drehbar gelagerte Fensterläden, die mittels Bänder an einem festen Bauteil, beispielsweise eine Wand, angebracht sind. In einer erfindungsgemäßen Vorrichtung zum Schwenken drehbar gelagerter Flügelelemente (1), die mittels Bänder (2) an einem festen Bauteil (3) angebracht sind, wird eine Antriebskraft zum Schwenken eines Flügelelements (1) auf ein Schwenkelement (4) übertragen, das drehfest mit einem Band (2) verbunden ist. Eine Antriebseinheit (5) zum Erzeugen der Antriebskraft ist in dem Flügelelement (1) angeordnet und dort vor Witterungseinflüssen und Manipulationsversuchen geschützt.
Abstract:
Bei einer Vorrichtung zum Öffnen und Schließen einer an einer Fahrzeugkarosserie (1) angelenkten Heckklappe (2) oder eines Heckdeckels ist die Heckklappe (2) oder der Heckdeckel mit Unterstützung einer an der Heckklappe (2) oder am Heckdeckel und an der Fahrzeugkarosserie (1) abgestützten Teleskopfedereinrichtung (3) verschwenkbar, wobei Teleskopfedereinrichtung (3) ortsveränderlich an der Fahrzeugkarosserie (1) und/oder an der Heckklappe (2) bzw. dem Heckdeckel abgestützt ist. Dadurch ist der Kraftangriffspunkt (4) in Richtung des Pfeiles C so verschiebbar, dass das von der Teleskopfedereinrichtung (3) in Bezug auf die Anlenkung (10) der Heckklappe (2) an der Fahrzeugkarosserie (1) ausgeübte Drehmoment (Federkraftmoment) beim Schließen der Heckklappe (2) um einen vorgebbaren Betrag kleiner und zum Öffnen der Heckklappe (2) um einen vorgebbaren Betrag größer ist als das von der Heckklappe (2) in Bezug auf deren Anlenkung (10) an der Fahrzeugkarosserie (1) ausgeübte Gewichtskraftmoment.
Abstract:
Die Erfindung richtet sich auf einen hydraulischen Drehflügelantrieb mit einem Türschlieβer (1) mit einem exzentrisch gelagerten, eine kreisrunde Wälzkurve aufweisenden Ritzel (6), welches mti einer am Kolben (4) angeordneten Zahnstange (5) kämmt, wobei eine besondere Ausgestaltung der Wälzkurve und der Zähne (9) der Zahnstange (5) in Anpassung an eine Evolventenverzahnung des Ritzels (6) erfolgt. Zur Erzielung eines optimalen Bewegungsablaufes des Kolbens (4) im Gehäuse (2) des Türschliesssers (1) ist eine verbessernde Ausgestaltung der Schliessverzögerung vorgesehen.
Abstract:
A liftgate force control assembly (20) adjusts the force required to move a liftgate (12) that is pivotally secured to a motor vehicle (10) using a hinge (14). The liftgate force control assembly includes a track (42) that is fixedly secured to the motor vehicle. A follower (46) is movably secured to the track. A strut (34, 36) has a movable end (26, 28) and a secured end (30, 32). The secured end (30, 32) is pivotally secured to the liftgate (12) and the movable end (26, 28) is pivotally secured to the follower (46). The strut (34, 36) defines a moment with respect to the hinge that secures the liftgate to the motor vehicle. A motor (50) is connected to the follower (46) to move the follower (46) along the track (42) changing the moment of the strut such that the force required to move the liftgate (12) changes as the moment changes.
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 drive device for a flap of a piece of furniture including at least one actuating arm which is activated by a spring device and is intended for moving the flap. A pushing-out device can move the flap from the closed position the opening direction toward the open position over a first opening-angle range (M1). The spring device exerts substantially no force on the flap in the first opening-angle range (M1), and the spring device moves the flap in the opening direction only in a second opening-angle range (M2), wherein the second opening-angle range (M2) adjoins the first opening-angle range (M1) or, at most, slightly overlaps the first opening-angle range.
Abstract:
The invention relates to a drive mechanism having a drive motor and a drive element drivable by the drive motor. A first worm gear, which has a first worm gear shaft and a first worm wheel, and a second worm gear, which has a second worm gear shaft and a second worm wheel, are connected between the drive motor and the drive element.
Abstract:
An actuator device for automatically activating the vehicle door of a motor vehicle, in particular the tailgate, is disclosed. The actuator device includes an electromotive drive and a radially extending arm attached either to the vehicle door or to a vehicle bodywork, and set in motion by the electromotive drive, the electromotive drive having an electrical motor and a gearbox driven by the motor, characterized in that, the gearbox has a wobble mechanism.
Abstract:
An actuator for a flap on an item of furniture includes at least one actuating arm that is mounted to pivot between a closed position and an open position in order to move the flap, a spring device for acting on the actuating arm, and a transmission mechanism for transmitting the force of the spring device onto the actuating arm. An adjustment device allows the transmission mechanism to be shifted between at least two operating positions. In a first operating position, the spring device applies a closing force, in the direction of the closed position, onto the actuating arm which is in an opening position immediately upstream of said closed position. In a second operating position, when said actuating arm is in the aforementioned, immediately-upstream opening position, the spring device exerts a force which acts in the direction of the open position.
Abstract:
A spring winding device, a counterbalancing force adjustment device for a counterbalancing mechanism, and a method of adjusting an amount of force stored in a spring of a counterbalancing mechanism are provided. The spring winding device includes a support bracket, a worm gear, and a drive gear. The worm gear is rotatably coupled to the support bracket and includes a mount portion for coupling a first end cone thereto. The drive gear is rotatably disposed adjacent the support bracket and is drivingly engaged with the worm gear. A rotation of the drive gear causes the worm gear to rotate within the support bracket. The spring winding device does not require pretensioning using winding rods, maintains rigidity and alignment when a counterbalancing force is applied, and decreases a cost and a complexity of the counterbalancing mechanism.
