Abstract
(DE)
Die Erfindung betrifft eine Vorrichtung, umfassend: eine Lochplatte (4) mit einer Vielzahl von Bohrungen; mindestens einen Stift (5, 15, 25, 25, 35, 45, 55, 65, 75, 85), der durch eine Bohrung der Lochplatte (4) ragt und der in Axialrichtung beweglich ist; eine elektromagnetische Betätigungsvorrichtung (6, 16, 66, 116) zum Bewegen des Stiftes (5, 15, 25, 25, 35, 45, 55, 65, 75, 85). Ein vereinfachter Aufbau wird dadurch erreicht, daß der Stift (5, 15, 25, 25, 35, 45, 55, 65, 75, 85) mindestens zwei stabile Stellungen aufweist, in denen er durch die Kraft eines Permanentmagnets (5e, 5g, 5j, 8, 55c, 67) gehalten wird, wobei der Stift (5, 15, 25, 25, 35, 45, 55, 65, 75, 85) in einer stabilen Stellung aus der zugehörigen Bohrung der Lochplatte (4) nicht hervorragt.
(EN)
The invention relates to a device comprising: a perforated plate (4) with a plurality of drillings; at least one pin (5, 15, 25, 25, 35, 45, 55, 65, 75, 85) projecting through a drilling in the perforated plate (4) and axially movable; an electromagnetic actuator (6, 16, 66, 116) to move the pin (5, 15, 25, 25, 35, 45, 55, 65, 75, 85). A simplified structure is obtained by the fact that the pin (5, 15, 25, 25, 35, 45, 55, 65, 75, 85) has at least two stable positions in which it is held by the force of a permanent magnet (5e, 5g, 5j, 8, 55c, 67). The pin (5, 15, 25, 25, 35, 45, 55, 65, 75, 85) does not project from the corresponding drilling in the perforated plate (4) when in a stable position.
(FR)
La présente invention concerne un dispositif comportant: une plaque (4) percée de trous multiples; au moins une broche (5, 15, 25, 25, 35, 45, 55, 65, 75, 85) qui fait saillie à travers un trou de la plaque à trous (4) et est mobile dans le sens axial; un dispositif d'actionnement électromagnétique (6, 16, 66, 116) qui sert à déplacer la broche (5, 15, 25, 25, 35, 45, 55, 65, 75, 85). La construction est simplifiée grâce au fait que la broche (5, 15, 25, 25, 35, 45, 55, 65, 75, 85) présente au moins deux positions stables dans lesquelles elle est retenue par la force d'un aimant permanent (5e, 5g, 5j, 8, 55c, 67). En position stable, la broche (5, 15, 25, 25, 35, 45, 55, 65, 75, 85) ne fait pas saillie à travers le trou qui lui correspond dans la plaque (4).
