Description

Technisches GebietTechnical area

Die Erfindung bezieht sich auf einen elektromagnetisch gesteuerten Verschluss für eine Maschinentür, vorzugsweise eine Waschmaschinentür, nach dem Oberbegriff des Anspruchs 1. Dieser Verschluss weist ein Grundlager auf, das eine verschwenkbar angeordnete Handhabe trägt, die über einen Sperrhebel mit einer auf dem Grundlager angeordneten Schwenkfalle verbunden ist, wobei der an der Handhabe gelagerte Sperrhebel einen mit einer schrägen Steuerfläche versehenen Haken aufweist, der in der Verriegelungsposition einen Bolzen des Grundlagers festhält, wobei das Grundlager an der Maschinentür befestigbar ist, wobei der Verschluss eine Klobengrundplatte aufweist, die mit dem Maschinengehäuse verbindbar ist und wobei in der Klobengrundplatte ein Verriegelungsstift liegt.The invention relates to an electromagnetically controlled closure for a machine door, preferably a washing machine door, according to the preamble of claim 1. This closure has a base bearing, which carries a pivotally arranged handle, which is connected via a locking lever with a pivot bearing arranged on the base camp is, wherein the locking lever mounted on the handle having a provided with a sloping control surface hook which holds a bolt of the base in the locking position, the base bearing is fastened to the machine door, the closure having a Klobengrundplatte which is connectable to the machine housing and wherein in the Klobengrundplatte a locking pin is located.

Stand der TechnikState of the art

Bekannt ist ein Verschluss mit den oben genannten Merkmale ( DE 17 82 224 U ), dessen Handhabe einen Auslöseknopf aufweist, der den Sperrhebel löst. Der Bedienende muss zunächst den Auslöseknopf gegen Federdruck drücken. Hierdurch wird die Sperre zwischen dem Grundlager und der Handhabe aufgehoben, sodass die Handhabe um einen bestimmten Winkel von der Türebene abklappt und die Schwenkfalle ebenfalls unter Federkraft gegenüber dem Grundlager verschwenkt wird. 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.A closure with the above features is known ( DE 17 82 224 U ), the handle of which has a release button that releases the locking lever. The operator must first press the release button against spring pressure. As a result, the lock between the base and the handle is released, so that the handle folds down by a certain angle from the door level and the pivot latch is also pivoted by spring force relative to the base camp. In the described closure, there may be problems when the operator overlooks the release button in the handle and pulls directly with great force on the handle. Also could arise in the often inexperienced operators the impression that you have to raise the door after pressing the trigger button and the popping of the handle now by force.

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. Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass in der Klobengrundplatte ein elektromagnetisch bewegter Verriegelungshebel geführt ist und dass der Sperrhebel gegen das obere Ende eines zweiarmigen Umlenkhebels drückt, dessen unteres Ende von dem gehäuseseitigen, elektrisch gesteuerten Verriegelungshebel festgehalten ist, sodass durch Ziehen an der Handhabe der Umlenkhebel bei Freigabe ausweichen, der Sperrhebel den Bolzen passieren und die einen Anschlag für den Verriegelungshebel aufweisende Schwenkfalle sich von dem gehäuseseitigen Verriegelungsstift lösen kann.It is an object of the invention to reshape the closure so that you can do without loss of security on the release button. The closure should be foolproof in a sense that either nothing can be moved or the door can be fully opened with the handle. The object is achieved in that in the Klobengrundplatte an electromagnetically moved locking lever is guided and that the locking lever presses against the upper end of a two-armed reversing lever, the lower end of which is held by the housing side, electrically controlled locking lever, so by pulling the handle of the Disengage lever when released, the locking lever pass the bolt and a stop for the locking lever having pivot latch can be detached from the housing-side locking pin.

In Figur 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 is a handle which is open in the left third of the bottom to accommodate the individual parts of the closure. In this cavity rests a base camp 2, which is connected via a pin 13 with the handle 1.

Eine Schwenkfalle 3 ist über einen Ansatzbolzen 9 in dem Grundlager 2 begrenzt schwenkbar angeordnet. Hinter der Schwenkfalle 3 ist ein Umlenkhebel 4 gelagert, dessen Form aus Figur 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 Schwenkfallenfeder 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 pivotal latch 3 is arranged pivotally limited by a shoulder bolt 9 in the base camp 2. Behind the pivot latch 3, a lever 4 is mounted, the shape of FIG. 2 is better to see. The upper, right end of the reversing lever 4 rests on a locking lever 5, which is mounted with a pin 14 in the handle 1. The lever 5 has a hook provided with a slightly inclined control surface, which holds a bolt 6 of the base camp 2. The reversing lever 4 is held by a return spring 7 in the rest position. A pivotal latch spring 8 holds the pivoting latch 3 in the desired position. At the upper end of the pivot latch 3, a roller 18 is mounted, which rolls on a curved piece in the handle 1.

In der Öffnung der Schwenkfalle liegt ein Verriegelungsstift 12, der entsprechend Figur 2 über eine Klobengrundplatte 10 mit dem nicht dargestellten Maschinengehäuse verbunden ist. In der Klobengrundplatte 10 ist ein abgewinkelter Verriegelungshebel 11 geführt, der in Figur 2 das untere Ende des Umlenkhebels 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 pivot latch is a locking pin 12, which accordingly FIG. 2 is connected via a Klobengrundplatte 10 with the machine housing, not shown. In the Klobengrundplatte 10 an angled locking lever 11 is guided in FIG. 2 blocked the lower end of the bell crank. As long as the lever 4 is held, the locking lever 5 can not move. The handle 1 thus remains blocked.

Figur 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. FIG. 3 represents the transition to the opening: When the locking lever 11 is actuated electromagnetically and dives back into the plane to the rear, can be brought about by lifting the handle 1 an opening: The locking lever 5 is pressed by the slightly inclined control surface and the bolt 6 to the left , the deflection lever 4 moves against the Clockwise and the pivot latch 3 device in an inclined position in which it can be detached from the locking pin 12.

Die Schnitte nach Figur 4 bis 7 dienen der weiteren Erläuterung:

  • Figur 4 zeigt den Schnitt in der Ebene A-A nach Figur 1. In der Handhabe 1 ruht das Grundlager 2. In diesem sind die Schwenkfalle 3 und der Umlenkhebel 4 gelagert. Die Schwenkfalle 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.
  • Figur 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.
  • In Figur 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 Schwenkfalle gelagerte Rolle 18, die sich auf einem Kurvenstück 15 (Figur 10) bewegt.
  • In Figur 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.
  • Figur 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.
  • Figur 9 zeigt eine ähnliche Ansicht wie Figur 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.
  • Figur 10 stellt perspektivisch die Einzelteile vor: Unter der Handhabe 1 liegt das Grundlager 2, darunter die Schwenkfalle 3 mit dem Anschlag 3a. Daneben ist der Umlenkhebel 4 zu sehen. Der Bolzen 14 verbindet den Sperrhebel 5 mit der Handhabe 1. Der Ansatzbolzen 9 dient der Lagerung von Schwenkfalle 3 und Umlenkhebel 4 in dem Grundlager 2.
    Der Bolzen 6 wird in das Grundlager 2 eingesetzt und dient als Anschlag für den Haken des Sperrhebels 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 Schwenkfalle 3.
    Ein weiterer Ansatzstift 20 wird ebenfalls in die Schwenkfalle 3 eingepresst und hält dort die in Figur 1 dargestellte Rückstellfeder 7 des Umlenkhebels 4 fest. Mit Hilfe des Bolzens 13 wird die Handhabe 1 auf dem Grundlager 2 schwenkbar befestigt.
  • Figur 11 zeigt in den Umrisslinien die Handhabe 1, das Grundlager 2, die Schwenkfalle 3 mit dem Anschlag 3a, den Umlenkhebel 4 und den Sperrhebel 5, der gerade den Bolzen 6 überwindet. Der Hebel 4 ist bereits im Uhrzeigersinn verschwenkt, die Schwenkfalle 3 befindet sich aber noch - obwohl entriegelt - in der Ruhestellung. Dies ändert sich aber durch weiteres Anheben der Handhabe 1. Die Steuerfläche des Sperrhebels 5, über die der Bolzen 6 gleitet, weist gegenüber der Längsachse D-D des Hebels einen Winkel von etwa 95° auf.
The cuts after FIGS. 4 to 7 serve for further explanation:
  • FIG. 4 shows the section in the plane AA FIG. 1 , In the handle 1, the base camp rests 2. In this, the pivotal latch 3 and the lever 4 are stored. The pivotal latch 3 holds the locking pin 12, which rests in the Klobengrundplatte 10. The locking lever 11 is in front of the lower end of the reversing lever 4 and holds it firmly.
  • FIG. 5 shows that the locking lever 11 is moved to the left in the release position. The lever 4 can thus yield when the handle 1 is pulled up.
  • In FIG. 6 the section in the plane BB shows the handle 1, the basic bearing 2, the pivoting latch 3, the reversing lever 4, the locking lever 5, the latch spring 8, the shoulder bolt 9 and a roller 18 mounted in the pivoting latch and resting on a curved piece 15 (FIG. FIG. 10 ) emotional.
  • In FIG. 7 the section CC is guided by the locking lever 5. It is mounted on the bolt 14 in the handle 1 and holds on the bolt 6, the base camp 2 firmly.
  • FIG. 8 shows - partially cut open - the handle 1, the basic bearing 2, the pivotal latch 3, and the bolts 6, 13 and 14. The bolt 13 connects the handle and base camp. At the lower, left end of the pivot latch 3, a stop 3a is provided, which rests in the locked state on the locking lever 11. The handle 1 carries the curved piece 15, which has 18 contact with the roller.
  • FIG. 9 shows a similar view as FIG. 8 , but without the pivot latch 3. It recognizes the lever 4, the upper half is covered by the base 2. On the lower surface of the base camp 2 threaded bushes 2a and 2b are incorporated, which serve to attach the closure on the door leaf.
  • FIG. 10 represents in perspective the items: Under the handle 1 is the base camp 2, including the pivot latch 3 with the stop 3a. In addition, the lever 4 can be seen. The bolt 14 connects the locking lever 5 with the handle 1. The shoulder bolt 9 is used to support the pivoting latch 3 and lever 4 in the base camp. 2
    The bolt 6 is inserted into the base bearing 2 and serves as a stop for the hook of the locking lever. 5
    15 is a curved piece of abrasion resistant material, which is fastened by means of screws 16, 17 in the handle 1. A roller 18, which is mounted by means of a neck pin 19 in the pivot case 3, rolls on the curved piece 15 from. The shape of the curve piece 15 controls the pivoting movement of the pivoting latch 3.
    Another approach pin 20 is also pressed into the pivot case 3 and holds there in the FIG. 1 shown return spring 7 of the reversing lever 4 fixed. With the help of the bolt 13, the handle 1 is pivotally mounted on the base 2.
  • FIG. 11 shows in the contours of the handle 1, the base 2, the pivotal latch 3 with the stopper 3a, the lever 4 and the locking lever 5, which just overcomes the bolt 6. The lever 4 is already pivoted in the clockwise direction, the pivotal latch 3 is still - although unlocked - in the rest position. This changes but by further raising the handle 1. The control surface of the locking lever 5, over which the bolt 6 slides, has with respect to the longitudinal axis DD of the lever at an angle of about 95 °.

Im rechten Teil der Handhabe 1 erkennt man das Kurvenstück 15, das mit Hilfe der Schrauben 16, 17 befestigt ist. Das Kurvenstück 15 ist zum Teil durch den Umlenkhebel 4 verdeckt, sodass man die Rolle 18 der Schwenkfalle 3 nicht sehen kann.In the right part of the handle 1 can be seen the curved piece 15, which is fastened by means of the screws 16, 17. The curve piece 15 is partially covered by the lever 4, so you can not see the roller 18 of the pivot latch 3.

Gewerbliche VerwertbarkeitCommercial usability

Der neuartige elektromagnetisch gesteuerte Verschluss ist vorwiegend für eine Tür geeignet, die den Innenraum einer Maschine vom Außenraum abtrennt. Die elektrische Verriegelung soll dabei sicherstellen, dass das Bedienungspersonal nicht in bewegte Medien der Maschine hineingreifen kann.
Die Erfindung ist geeignet, die Fertigung derartiger Verschlüsse zu verbilligen und die Bedienung der damit ausgerüsteten Maschinen durch wechselndes oder ungeübtes Personal sicher zu machen.The novel electromagnetically controlled shutter is primarily suitable for a door that separates the interior of a machine from the outside. The electrical interlock should thereby ensure that the operating personnel can not reach into moving media of the machine.
The invention is suitable for reducing the production of such closures and to make the operation of the machines equipped with them safe by changing or inexperienced personnel.
