Abstract:
A magnetic field based mechanical apparatus is disclosed. The apparatus is based on coupled attracting or opposing magnets in conjunction with the insertion or removal of a magnetic field modifier. In the preferred embodiment, two repelling magnets (11, 12) are drawn together with the insertion of a magnetic field modifier (13). The field modifier may be another magnet having an opposing pole. Removal of the field modifier returns the forces to their original states. This oscillating motion may be driven with a low energy and/or small power supply. The resulting motion of the opposing magnets can drive mechanical system such as a linear, gear, ratchet, or reciprocating drive.
Abstract:
The invention relates to a piece of furniture (1) comprising a furniture body (2), a furniture part (3) that is mounted so as to be mobile relative to the furniture body (2) and a drive device (5) for moving the furniture part, which drive device can be triggered via a switch element (4) and comprises at least one motor. The switch element (4) is covered by the furniture part (3) in or on the furniture body (2) when the furniture part (3) is closed and an indirect actuation of the switch element (4) via a force exerted by a user and impacting the mobile furniture part (3) triggers the drive unit. The switch element (4) triggering the drive device (5) is accessible for the user and can be directly actuated when the furniture part (3) is moved out of the closed position.
Abstract:
Device for transmitting rotary motion in a diverter switch comprising a motion-transmitting member for transforming an alternating rotary motion of a drive shaft (1a) into a unidirected rotary motion of a driven body (2) driven about driven shaft (2a). The motion-transmitting member comprises an intermediate body (3) rotatable about an intermediate shaft (3a). A mechanical energy accumulation member (17) is connected to the driven body. The motion-transmitting member for transforming the alternating rotary motion of the drive shaft (1a) into a unidirected rotary motion of the driven shaft (2a) comprises an intermediate motion member connected to a crank mechanism (100). The motion member is provided with engagement means (102) for transforming the linear mo- tion into a unidirected rotary motion of the intermediate shaft (3a) via drive members (103).

Abstract:
The invention relates to a mechanism for opening and closing a circuit breaker having an operating rod for moving the contacts of the circuit breaker between an open position and a closed position, which mechanism comprises: - a frame - a freewheel mechanism with a driveshaft and a driven shaft, wherein the freewheel mechanism is arranged rotatably in the frame; - spring means coupling the driveshaft of the freewheel mechanism with the frame; - locking means for locking the driven shaft of the freewheel mechanism; - a cam wheel arranged on the driven shaft, wherein the cam wheel comprises at least two cam lobes for actuating the operating rod of a circuit breaker.
Abstract:
Le dispositif de commande possède une pièce principale rigide rassemblant une grande partie des éléments fonctionnels de ce type de commande. Elle est constituée des deux parties (7A, 7B) d'un arbre tournant, entre lesquelles sont placés une came (4) et un bras support (6) reliés par un pivot (5) qui est décalé par rapport à l'axe de rotation. Une roue dentée, possédant une denture intérieure, est placée autour du bras support (6) qui est doté d'un système à cliquets (8). La roue dentée (1) est entraînée par sa denture extérieure (3) par un moteur, au moyen d'un pignon intermédiaire. Le pivot (5) commande la compression du ressort d' actionnement par la rotation de l'ensemble. Application aux disjoncteurs et interrupteurs de haute et moyenne tensions.
Abstract:
Ein Kontakte (4) tragender Schieber (3) des Schalters ist mit einer sich in der Schieberichtung erstreckenden sägeartigen Antriebsverzahnung (7) versehen, die in der Schieberichtung zum einem Betätiger (2) hin ansteigenden Antriebsschrägen (9) aufweist. Der senkrecht zur Verschieberichtung bewegbare Betätiger (2) ist mit einem entlang der Antriebsschrägen (9) gleitbaren Antriebsnocken (10) versehen, der beim Eindrücken den Schieber (3) um den Gleitweg einer Antriebsschräge (9) weiter schiebt. Eine am Schieber (3) ausgebildete, sich in der Schieberichtung erstreckende Rastverzahnung (11) und ein stationäres federnd auslenkbares nockenartiges Rastelement (13) ziehen durch ihre Schnappwirkung den Schieber (3) um einen Resthub in eine definierte Rastlage, in der die Kontakte (4) mit stationären Gegenkontakten (6) des Schalters kontaktiert sind. Dadurch wird die Handhabung und Herstellung eines solchen Schalters verbessert.
Abstract:
Eine Schaltgeräteantriebseinrichtung weist ein Getriebe mit einer Welle (1) auf. Koaxial zur Welle (1) ist ein Getrieberad (3) angeordnet. Die Welle (1) und das Getrieberad (3) sind insbesondere relativbewegungsabhängig schaltbar über eine Kuppeleinrichtung miteinander verbunden. Die Kuppeleinrichtung ist insbesondere unabhängig von einer Relativbewegung zwischen Getrieberad (3) und Welle (1) zumindest teilweise innerhalb einer Hüllkontur des Getrieberades (3) angeordnet.
