Description
Erfindungsgemäß wird es dadurch erreicht, daß im Zusammenwirken mit einem im Gehäuse angeordneten ferromagnetische!! Zwischenglied durch ein weiteres zwischen dem Verriegelungsgestänge und dem Programmzeitschalter drehbar angeordnetes Zwischenglied einerseits die Schaltbarkeit des Programmzeitschalters in Abhängigkeit von der Verschlußstellung des mit einem Permanentmagneten versehenen Gehäusedeckels und anderseits die Öffnung des Gehäusedeckels in Abhängigkeit von der Schaltstellung des Programmzeitschalters über eine in der Drehachse des Programmzeitschalters axial verschiebbar angeordnete Scheibe gesteuert wird.According to the invention it is achieved in that in cooperation with a ferromagnetic arranged in the housing !! Intermediate member by another between the locking linkage and the program timer rotatably arranged intermediate member on the one hand, the switchability of the program timer in response to the closed position of the housing provided with a permanent magnet cover and on the other hand, the opening of the housing cover in response to the switching position of the program timer via a in the axis of rotation of the program time switch axially slidably arranged disc is controlled.
Ein weiteres Erfindungsmerkmal besteht darin, daß das im Gehäuse drehbar angeordnete Zwischenglied mit einer Scheibe versehen und mit einem außerhalb des Gehäuses liegenden Bedienelement gekoppelt ist.Another feature of the invention is that the rotatably disposed in the housing intermediate member provided with a disc and is coupled to a control element located outside of the housing.
Erfinderisch ist ferner die Anordnung des Zwischengliedes gegenüber dem Programmzeitschalter mit einem kleineren Drehachsenabstand als die Hälfte der Summe der Außendurchmesser beider Scheiben, welche je eine Aussparung in Größe und Form des Überlappungsbereiches aufweisen. Die Lage des ferromagnetischen Zwischengliedes nach der Verriegelungsstelle bezogen auf die Verriegelungsrichtung und eine Verlängerung am Verriegelungssteg sind ebenfalls Erfindungsmerkmale.Inventive is also the arrangement of the intermediate member relative to the program timer with a smaller axis of rotation distance than half the sum of the outer diameter of both discs, which each have a recess in size and shape of the overlap region. The position of the ferromagnetic pontic to the locking point with respect to the locking direction and an extension of the locking bar are also features of the invention.
Die Erfindung soll nachstehend an einem Ausführungsbeispiel erläutert werden. Dabei zeigen:The invention will be explained below using an exemplary embodiment. Showing:
Fig. 1: die Draufsicht der erfindungsgemäßen Sicherheitseinrichtung in Einschalt- und VerriegelungsstellungFig. 1: the top view of the safety device according to the invention in switch-on and locking position
Fig. 2: die Vorderansicht in VerriegelungsstellungFig. 2: the front view in the locked position
Fig.3: die Seitenansicht in Verriegelungsstellung3: the side view in the locked position
Fig.4: die Draufsicht in Ausschalt- und VerriegelungsstellungFig.4: the top view in off and locking position
Fig. 5: die Draufsicht in Ausschalt- und EntriegelungsstellungFig. 5: the plan view in off and unlocked position
Fig. 6: die Vorderansicht in EntriegelungsstellungFig. 6: the front view in unlocked position
Die Scheiben (1) und (2) sind so gestaltet und zusammen mit dem Verriegelungsgestänge (4) verkettet, daß einerseits bei Ausschaltstellung des Programmzeitschalters (3), d. h. bei einer bestimmten Stellung von Scheibe (1), eine Drehbewegung von Scheibe (2) und damit eine Bewegung des Verriegelungsgestänges (4) möglich ist und andererseits nur bei Verriegelungsstellung des Gehäusedeckels (5), d. h. bei einer bestimmten Stellung von Scheibe (2), eine Drehbewegung von Scheibe (1) und damit die Programmwahl und das Einschalten des Programmzeitschalters (3) möglich ist. Bei offenem Gehäusedeckel (5) blockiert die Drehbewegung von Scheibe (2) vor Freigabe der Drehbeweglichkeit der Scheibe (1) über das Verriegelungsgestänge (4) ein ferromagnetisches Zwischenglied (6), welches bei geschlossenem Gehäusedeckel (5) durch den daran befestigten Permanentmagneten (7) aus der Bewegungsrichtung des Verriegelungsgestänges (4) gezogen wird, womit dann die Programmwahl und das Einschalten erfolgen kann. Die am Verriegelungssteg (8) angeordnete Verlängerung (9) sperrt den Weg des Verriegelungsgestänges (4) in Verriegelungsrichtung solange, bis das ferromagnetische Zwischenglied (6) in Folge des Deckelöffnens außerhalb des Anzugbereiches des Permanentmagneten (7) in Blockierstellung liegt.The discs (1) and (2) are designed and concatenated together with the locking linkage (4), that on the one hand in off position of the program timer (3), d. H. at a certain position of disc (1), a rotational movement of disc (2) and thus a movement of the locking linkage (4) is possible and on the other hand only in locking position of the housing cover (5), d. H. at a certain position of disc (2), a rotational movement of disc (1) and thus the program selection and switching on the program timer (3) is possible. When the housing cover (5) is open, the rotational movement of the disc (2) before releasing the rotational mobility of the disc (1) via the locking linkage (4) blocks a ferromagnetic intermediate member (6) which, when the housing cover (5) is closed, is secured by the permanent magnet (7 ) is pulled out of the direction of movement of the locking linkage (4), which then the program selection and switching can be done. The extension (9) arranged on the locking web (8) blocks the path of the locking linkage (4) in the locking direction until the ferromagnetic intermediate link (6) lies outside the tightening region of the permanent magnet (7) in blocking position as a result of the lid opening.
