Abstract:
An actuating mechanism (3) for a pivotably mounted actuating arm (9), in particular for driving a flap (4) of an item of furniture (1), wherein the actuating arm (9) is acted upon by a spring device (5), and wherein an electric drive (16) acts on the actuating arm (9) via a transmission mechanism (13), and wherein the transmission ratio of angle of rotation (α) of the motor to angle of rotation (ß) of the actuating arm is varied over the angle of rotation range of the actuating arm by the transmission mechanism (13).
Abstract:
The invention relates to a device for pivoting rotatably mounted sash elements, especially rotatably mounted window shutters, that are applied to a fixed component, for example a wall, by means of strips. According to the invention, a driving force for pivoting a sash element (1) is transmitted to a pivoting element (4) that is connected to a strip (2) in a rotationally fixed manner. A drive unit (5) for generating the driving force is arranged in the sash element (1) where it is protected from atmospheric exposure and handling.
Abstract:
The invention relates to a force supporting device (10) for providing a load-dependent supporting force, particularly for a lowerable overhead luggage compartment (12) in an aircraft. The device (10) comprises a bracket (20) whose one end is attached to a supporting structure in a manner that enables it to pivot about an axis (P) and whose other end is designed for being connected to an object to which the supporting force should be applied. In addition, a gas-filled spring device (22) is provided whose one end is pivotally coupled to the bracket (20) and whose other end is pivotally coupled to one end of an oscillating lever (24) whose other end is pivotally attached to a bearing plate (18) and which can pivot relative to the bearing plate (18) between a first final position and a second final position. The oscillating lever (24) can be arrested at a number of positions in the area extending from its first final position to the second final position by means of an arresting device. A displacing device (46) serves to pivot the oscillating lever (24) according to a load determining device, which interacts with the adjusting device (46), between its first final position and its second final position.
Abstract:
The invention relates to a sliding rail door-closing device (1) having an eccentrically positioned pinion (6) comprising a circular working curve. Said pinion intermeshes with a toothed rack (5) arranged on a piston (4). The aim of the invention is to design the working curve and the teeth (9) of the toothed rack (5) in such a way that they are adapted to a toothing of the pinion (6). In order to optimise the movement sequence of the piston (4) in the housing (2) of the sliding rail door-closing device (1), the invention further relates to an improved embodiment of the closing delay.
Abstract:
Die Erfindung betrifft einen Drehtürantrieb mit einer elektromechanischen Vorrichtung, die das für das Öffnen und Schließen der Tür notwendige Schließmoment liefert, dabei wird das sich über den Öffnungswinkel der Tür in seinem Übersetzungsverhältnis ändernde Getriebe eine mit einer Abtriebswelle verbundene Führung und eine relativ zu der Führung und in dieser translatorisch bewegbare Mitnehmerrolle umfaßt, die mit einem in eine mit der Federanordnung in Verbindung stehende Zahnstange eingreifenden Ritzel verbunden ist, wobei die Drehachse der Abtriebswelle zu der Drehachse des Ritzels und die Drehachse der Mitnehmerrolle zu der Drehachse des Ritzels in vorbestimmten Abständen voneinander angeordnet sind, derart, daß beim Verdrehen von Abtriebswelle und Ritzel infolge des sich dabei ändernden Achsabstandes zwischen Abtriebswelle und Mitnehmerrolle sich das Übersetzungsverhältnis ändert.
Abstract:
Die Erfindung betrifft einen Drehtürantrieb mit einer elektromechanischen oder elektrohydraulischen Antriebsvorrichtung, die für das Öffnen und Schließen eines angeschlossenen Drehflügels das nötige Öffnungs- und Schließmoment liefert, wobei eine elektronische Regelung/Steuerung mit mindestens einem Speicher und mindestens einem Mikroprozessor aufgrund von Sensorsignalen das Öffnungs- bzw.- Schließmoment über ein auf einer Abtriebswelle angeordnetes Zahnrad abgibt, die über ein Gestänge und einen Betätigungsarm mit dem Drehflügel verbunden ist, wobei zwischen der Abtriebswelle des Drehflügelantriebes und dem Gestänge bzw. dem Betätigungsarm eine Vorrichtung 2 vorhanden ist, die einer Veränderung des Öffnungs- und Schließmomentes über den Drehwinkel des Drehflügels bewirkt.
Abstract:
A counterbalance system (10) for an upwardly acting door (D) movable on tracks (T, T) between a closed position and an open position having, a drive tube (31) adapted to be mounted above the door in the closed position, a cable drum assembly (30) mounted proximate each end of the drive tube, a cable connecting each cable drum assembly and the door, a cylindrical member (40) on the cable drum assembly, a cable receiving surface (42) on the cylindrical member extending laterally between the door and the tracks and receiving multiple layers (F, S) of the cable during movement of the door from the closed position to the open position, whereby the cable avoids engagement with the door during movement between the closed position and the open position.
Abstract:
A drive apparatus, in particular for the automatic actuation of a sliding door of a motor vehicle, comprising a fast running motor (1), the motor shaft (2) of which is connected to a transmission (3) with a large step-down ratio, the transmission having a first gear wheel (4) which can be secured against rotation, via a releasable blocking device (6), and a second rotatable gear wheel (8) which is rotationally fixedly connected to an output drive shaft and which is rotatable relative to the first gear wheel by the rotation of the motor when the first gear wheel is blocked, with the number of teeth of the first gear wheel only differing by a few teeth from the number of teeth of the second gear wheel and with the large step-down ratio being determined by this difference of the tooth numbers. By releasing the blocking device, the step-down ratio of the transmission changes. In particular a step-down ratio of 1:1 results. The transmission is thereby capable of being driven in reverse, so that a manual actuation of the sliding door of a motor vehicle is possible, without the requirement for a releasable clutch device between the sliding door and the drive apparatus.
