Description

Technisches GebietTechnical field

Die Erfindung bezieht sich auf einen elektromagnetisch gesteuerten Verschluss für eine Maschinentür, vorzugsweise eine Waschmaschinentür. Dieser Verschluss weist ein Grundlager auf, das eine schwenkbar angeordnete Handhabe trägt, die über einen Sperrhebel mit einer auf dem Grundlager angeordneten Schwenkfalle verbunden ist. Die Schwenkfalle trägt eine Nut, in die ein elektromagnetisch bewegter Verriegelungshebel eintauchen kann.The invention relates to an electromagnetically controlled Lock for a machine door, preferably a washing machine door. This closure has a base bearing which is pivotally arranged Handle carries a locking lever with one on the base bearing arranged pivot trap is connected. The swivel latch has a groove, into which an electromagnetically moved locking lever can be inserted.

Stand der TechnikState of the art

Bekannt ist ein Verschluss mit den obengenannten Merkmalen, dessen Handhabe einen Auslöseknopf aufweist, der den Sperrhebel löst.A closure with the above-mentioned features is known Handle has a release button that releases the locking lever.

Der Bedienende muss zunächst den Auslöseknopf drücken. Hierdurch wird die Sperre zwischen dem Grundlager und der Handhabe aufgehoben, so dass die Handhabe unter Federkraft um einen bestimmten Winkel von der Türebene abklappt und die Falle ebenfalls unter Federkraft gegenüber dem Grundlager verschwenkt wird. Solange aber die Falle elektromagnetisch verriegelt ist, kann diese nicht aus einem im Gehäuse fixierten Verriegelungsstift heraustreten. Die Tür lässt sich also erst dann aufziehen, wenn elektrisch entriegelt ist.The operator must first press the release button. This will the lock between the base camp and the handle lifted so that the handle under spring force by a certain angle from the Door level folds down and the latch also under spring force compared to the Base camp is pivoted. But as long as the trap is electromagnetic is locked, it cannot be fixed in the housing Step out of the locking pin. So the door can only be opened when electrically unlocked.

Bei dem beschriebenen Verschluss kann es Probleme geben, wenn das Bedienungspersonal den Auslöseknopf in der Handhabe übersieht und direkt mit großer Kraft an der Handhabe zieht. Auch könnte bei dem oft unerfahrenen Bedienungspersonal der Eindruck entstehen, dass man die Tür nach dem Betätigen des Auslöseknopfes und dem Aufspringen der Handhabe nun mit Gewalt aufziehen müsse. There may be problems with the closure described if this Operating personnel overlooked the trigger button in the handle and directly pulls the handle with great force. Also often could Inexperienced operators get the impression that you can open the door after pressing the release button and opening the handle now have to wind up with violence.

Darstellung der ErfindungPresentation of the invention

Es ist Aufgabe der Erfindung, den Verschluss so umzugestalten, dass man ohne Einbuße an Sicherheit auf den Auslöseknopf verzichten kann. Der Verschluss soll gewissermaßen narrensicher werden in dem Sinne, dass sich entweder gar nichts bewegen lässt oder die Tür mit der Handhabe voll geöffnet werden kann.It is an object of the invention to redesign the closure so that one can do without the release button without sacrificing safety. The Closure is supposed to become foolproof in the sense that either doesn't move anything or the door is full with the handle can be opened.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass der an der Handhabe gelagerte Sperrhebel, dessen Haken einen Bolzen des Grundlagers hält, eine schräge Steuerfläche aufweist und dass der Sperrhebel gegen das obere Ende eines zweiarmigen Umlenkhebels drückt, dessen unteres Ende von einem gehäuseseitigen, elektrisch gesteuerten Verriegelungshebel festgehalten ist, so dass durch Ziehen an der Handhabe der Umlenkhebel bei Freigabe ausweichen kann, der Sperrhebel den Bolzen passieren kann und die Schwenkfalle sich von einem gehäuseseitigen Verriegelungsstift lösen kann.The object is achieved in that the handle stored locking lever, the hook of which holds a bolt of the base bearing, one has sloping control surface and that the locking lever against the upper end of a two-armed bell crank presses, the lower end of one housing-side, electrically controlled locking lever is held, so that by pulling the handle of the bell crank when released can dodge, the locking lever can pass the bolt and the Swivel latch can come loose from a locking pin on the housing.

In Fig. 1 ist mit 1 eine Handhabe bezeichnet, die im linken Drittel von unten her offen ist, um die Einzelteile des Verschlusses aufzunehmen. In diesem Hohlraum ruht ein Grundlager 2, das über einen Bolzen 13 mit der Handhabe 1 verbunden ist.In Fig. 1, 1 denotes a handle, which is in the left third from below is open to accommodate the individual parts of the closure. In this Cavity rests in a base bearing 2, which is connected to the handle via a bolt 13 1 is connected.

Eine Schwenkfalle 3 ist über einen Ansatzbolzen 9 in dem Grundlager 2 begrenzt schwenkbar angeordnet. Hinter der Falle 3 ist ein Umlenkhebel 4 gelagert, dessen Form aus Fig. 2 besser zu ersehen ist. Das obere, rechte Ende des Umlenkhebels 4 ruht an einem Sperrhebel 5, der mit einem Bolzen 14 in der Handhabe 1 gelagert ist. Der Hebel 5 weist einen mit leicht geneigter Steuerfläche versehenen Haken auf, der einen Bolzen 6 des Grundlagers 2 festhält. Der Umlenkhebel 4 wird durch eine Rückstellfeder 7 in der Ruheposition gehalten. Eine Fallenfeder 8 hält die Schwenkfalle 3 in der Sollposition. Am oberen Ende der Schwenkfalle 3 ist eine Rolle 18 gelagert, die auf einem Kurvenstück in der Handhabe 1 abrollt.A pivot trap 3 is in the base bearing 2 via a shoulder bolt 9 limited pivoting. Behind the trap 3 is a bell crank 4 stored, the shape of Fig. 2 can be seen better. The top right end of the lever 4 rests on a locking lever 5 which with a bolt 14 in the handle 1 is stored. The lever 5 has a slightly inclined one Control surface provided hook on a bolt 6 of the base bearing 2 holds. The bell crank 4 is by a return spring 7 in the Rest position held. A latch spring 8 holds the swivel latch 3 in the Target position. At the upper end of the swivel latch 3, a roller 18 is mounted, that rolls on a curve in the handle 1.

In der Öffnung der Falle liegt ein Verriegelungsstift 12, der entsprechend Fig. 2 über eine Klobengrundplatte 10 mit dem nicht dargestellten Maschinengehäuse verbunden ist. In der Klobengrundplatte 10 ist ein abgewinkelter Verriegelungshebel 11 geführt, der in Fig. 2 das untere Ende des Unlenkhebels blockiert. Solange der Hebel 4 festgehalten ist, kann sich auch der Sperrhebel 5 nicht bewegen. Die Handhabe 1 bleibt somit blockiert.In the opening of the trap there is a locking pin 12 which corresponds to FIG. 2 via a block base plate 10 with the not shown Machine housing is connected. In the block base plate 10 is a angled locking lever 11 performed, the lower end in Fig. 2 of the steering lever blocked. As long as the lever 4 is held, can also do not move the locking lever 5. The handle 1 thus remains blocked.

Fig. 3 stellt den Übergang zur Öffnung dar: Wenn der Verriegelungshebel 11 elektromagnetisch betätigt wird und in die Zeichenebene hinein nach hinten wegtaucht, kann durch Anheben der Handhabe 1 eine Öffnung herbeigeführt werden: Der Sperrhebel 5 wird durch die leicht schräge Steuerfläche und den Bolzen 6 nach links gedrückt, der Umlenkhebel 4 bewegt sich entgegen dem Uhrzeigersinn und die Schwenkfalle 3 gerät in Schräglage, in der sie sich von dem Verriegelungsstift 12 lösen kann.3 shows the transition to the opening: when the locking lever 11 is actuated electromagnetically and into the drawing plane towards the rear dives away, an opening can be made by lifting the handle 1 be: The locking lever 5 is due to the slightly oblique control surface and Bolt 6 pressed to the left, the bellcrank 4 moves against Clockwise and the swivel latch 3 gets into an inclined position in which it moves away from can release the locking pin 12.

Die Schnitte nach Fig. 4 - 7 dienen der weiteren Erläuterung:
Fig. 4 zeigt den Schnitt in der Ebene A-A nach Fig. 1. In der Handhabe 1 ruht das Grundlager 2. In diesem sind die Schwenkfalle 3 und der Umlenkhebel 4 gelagert. Die Falle 3 hält den Verriegelungsstift 12 fest, der in der Klobengrundplatte 10 ruht. Der Verriegelungshebel 11 steht vor dem unteren Ende des Umlenkhebels 4 und hält diesen fest.The sections according to FIGS. 4-7 serve for further explanation:
FIG. 4 shows the section in the plane AA according to FIG. 1. The base bearing 2 rests in the handle 1. The pivot latch 3 and the deflection lever 4 are mounted in this. The trap 3 holds the locking pin 12, which rests in the block base plate 10. The locking lever 11 stands in front of the lower end of the bell crank 4 and holds it in place.

Fig. 5 zeigt, dass der Verriegelungshebel 11 nach links in die Freigabestellung gerückt ist. Der Umlenkhebel 4 kann somit nachgeben, wenn die Handhabe 1 hochgezogen wird.Fig. 5 shows that the locking lever 11 to the left in the release position has moved. The bell crank 4 can therefore yield when the handle 1 is pulled up.

In Fig. 6 zeigt der Schnitt in der Ebene B-B die Handhabe 1, das Grundlager 2, die Schwenkfalle 3, den Umlenkhebel 4, den Sperrhebel 5, die Fallenfeder 8, den Ansatzbolzen 9 und eine in der Falle gelagerte Rolle 18, die sich auf einem Kurvenstück 15 (Fig. 10) bewegt.In Fig. 6 the section in the plane B-B shows the handle 1, the base bearing 2, the swivel latch 3, the bell crank 4, the locking lever 5, the latch spring 8, the shoulder bolt 9 and a roller 18 mounted in the trap, which is on a curve piece 15 (Fig. 10) moves.

In Fig. 7 ist der Schnitt C-C durch den Sperrhebel 5 geführt. Er ist auf dem Bolzen 14 in der Handhabe 1 gelagert und hält über den Bolzen 6 das Grundlager 2 fest.In Fig. 7, the section C-C is performed by the locking lever 5. He is on the Bolt 14 stored in the handle 1 and holds on the bolt 6 Base camp 2 fixed.

Fig. 8 zeigt - teilweise aufgeschnitten - die Handhabe 1, das Grundlager 2, die Schwenkfalle 3, sowie die Bolzen 6, 13 und 14.Der Bolzen 13 verbindet Handhabe und Grundlager. Am unteren, linken Ende der Schwenkfalle 3 ist ein Anschlag 3a vorgesehen, der im Sperrzustand auf dem Verriegelungshebel 11 ruht. Die Handhabe 1 trägt das Kurvenstück 15, das mit der Rolle 18 Kontakt hat.8 shows - partially cut away - the handle 1, the base bearing 2, the swivel latch 3, as well as the bolts 6, 13 and 14. The bolt 13 connects Handle and base camp. At the lower, left end of the swivel latch 3 is a stop 3a is provided in the locked state on the locking lever 11 rests. The handle 1 carries the curve piece 15, which with the roller 18th Has contact.

Fig. 9 zeigt eine ähnliche Ansicht wie Fig. 8, allerdings ohne die Schwenkfalle 3. Man erkennt den Umlenkhebel 4, dessen obere Hälfte von dem Grundlager 2 verdeckt wird. An der unteren Fläche des Grundlagers 2 sind Gewindebuchsen 2a und 2b eingearbeitet, die der Befestigung des Verschlusses am Türblatt dienen.Fig. 9 shows a view similar to Fig. 8, but without the Swivel trap 3.

Der Ansatzbolzen 9 dient der Lagerung von Schwenkfalle 3 und Umlenkhebel 4 in dem Grundlager 2.10 shows the individual parts in perspective: under the handle 1 the base bearing 2, including the swivel latch 3 with the stop 3a. In addition, the bell crank 4 can be seen. The bolt 14 connects the Locking lever 5 with the handle 1. The shoulder bolt 9 is used for the storage of Swivel latch 3 and reversing lever 4 in the base bearing 2.

Der Bolzen 6 wird in das Grundlager 2 eingesetzt und dient als Anschlag für den Haken des Sperrhebels 5.The bolt 6 is inserted into the base bearing 2 and serves as a stop for the hook of the locking lever 5.

Mit 15 ist ein Kurvenstück aus abriebfestem Material bezeichnet, das mit Hilfe der Schrauben 16, 17 in der Handhabe 1 befestigt wird. Eine Rolle 18, die mittels eines Ansatzstiftes 19 in der Schwenkfalle 3 gelagert wird, rollt auf dem Kurvenstück 15 ab. Die Form des Kurvenstückes 15 steuert die Schwenkbewegung der Falle 3.15 with a curve piece made of abrasion-resistant material is referred to With the help of screws 16, 17 is fastened in the handle 1. A roll 18, which is stored in the swivel latch 3 by means of a shoulder pin 19, rolls on the curve piece 15. The shape of the curve piece 15 controls the Swiveling movement of the trap 3.

Ein weiterer Ansatzstift 20 wird ebenfalls in die Schwenkfalle 3 eingepresst und hält dort die in Fig. 1 dargestellte Rückstellfeder 7 des Umlenkhebels 4 fest. Mit Hilfe des Bolzens 13 wird die Handhabe 1 auf dem Grundlager 2 schwenkbar befestigt.Another shoulder pin 20 is also pressed into the swivel latch 3 and holds there the return spring 7 of the bell crank 4 shown in FIG. 1 firmly. With the help of the bolt 13, the handle 1 is on the base bearing 2 pivotally attached.
