Description

Technisches GebietTechnical field

Die Erfindung betrifft einen Verschluß für Türen von Geräten, in denen Waren oder Lebensmittel erhöhter Temperatur und/oder Druck ausgesetzt sein können, bestehend aus einem Schließzapfen, der quer zu seiner Längsachse mindestens eine Rastvertiefung aufweist, und einem Riegelelement, das unter Federkraft in die genannte Rastvertiefung eintauchen kann.The invention relates to a closure for doors of devices in which goods or Foods may be exposed to increased temperature and / or pressure, consisting of a locking pin which is transverse to its longitudinal axis at least one locking recess has, and a locking element which under spring force in the said recess can immerse.

Stand der TechnikState of the art

Aus der DB 42 08 216 A1 ist ein Türverschluß, vorzugsweise für Heißgerätetüren, bekannt geworden, der folgenden Aufbau aufweist: In die Tür ist ein Schließzapfen eingesetzt, der unverschieblich drehbar gelagert ist und außenseitig einen Handgriff aufweist. Der Schließzapfen ist mit einer Rückholfeder gekoppelt und weist eine Riegelnut auf, die in einem bestimmten Umfangsabschnitt angeordnet ist. Eine Wand der Riegelnut ist der Türfläche zugewandt, verläuft also parallel zur Türfläche.A door lock, preferably for hot appliance doors, is known from DB 42 08 216 A1 has the following structure: A locking pin is inserted into the door, which is immovably rotatably mounted and has a handle on the outside. The Locking pin is coupled to a return spring and has a locking groove that in a certain circumferential section is arranged. One wall of the locking groove is that Facing the door surface runs parallel to the door surface.

Am Gerätegehäuse ist ein Schloßkasten vorgesehen, der eine Öffnung für das Einführen des Schließzapfens aufweist. In dem Schloßkasten ist ein quer zur Bewegungsbahn des Schließzapfens verschiebbares Riegelglied gelagert, das unter Federkraft steht und gegen den Schließzapfen gepreßt wird.A lock case is provided on the device housing and has an opening for insertion of the locking pin. In the lock case is a cross to the trajectory of the Locking pin slidable locking member mounted, which is under spring force and against the locking pin is pressed.

Das Riegelglied ist als Riegelschieber ausgebildet, der in zwei unterschiedliche Nuten des Schließzapfens eingreifen kann. Wenn die Tür fest verschlossen ist, ruht der Riegelschieber in der inneren, dem Türblatt benachbarten Nut. Die Rückholfeder stellt den Schließzapfen auf diejenige Drehstellung ein, in der die Axialebene der ersten Nut mit der Bewegungsbahn des Riegelschiebers fluchtet.The locking member is designed as a locking slide, which in two different grooves Can engage locking pin. When the door is closed securely, the bolt slide stops in the inner groove adjacent to the door leaf. The return spring provides the locking pin to the rotational position in which the axial plane of the first groove with the The trajectory of the bolt slide is aligned.

Beim Schließen der Tür wird der Schließzapfen so weit in die Aufnahmeöffnung des Schloßkastens gedrückt, bis der Riegelschieber in die erste Nut einrastet. Dabei ist die Türdichtung zusammengepreßt.When the door is closed, the locking pin is pushed so far into the receiving opening of the Lock case pressed until the bolt slide engages in the first groove. Here is the Door seal pressed together.

Zum Öffnen der Tür wird der Schließzapfen um seine Längsachse gedreht, bis der Riegelschieber aus der ersten Nut herausgedrückt ist, der Schieber also auf der Grundfläche der zweiten Nut gleiten kann. Die Rückfederkraft der Türdichtung drückt das Türblatt um einige mm oder cm auf, bis die Bewegung durch die Anschlagfläche der zweiten Nut begrenzt wird. In dieser Stellung wird das Türblatt so lange festgehalten, bis der Handgriff erneut, aber jetzt um einen größeren Winkel, verdreht wird. Der Riegelschieber wird dann so weit hochgedrückt, bis seine Kante über den zylindrischen Teil des Schließzapfens gleiten kann, so daß die Tür voll zu öffnen ist.To open the door, the locking pin is rotated about its longitudinal axis until the Latch slide is pushed out of the first groove, i.e. the slide on the base the second groove can slide. The spring force of the door seal pushes the door leaf over a few mm or cm until the movement through the stop surface of the second groove is limited. The door leaf is held in this position until the handle again, but now by a larger angle, is rotated. The bolt slide will then pushed so far until its edge over the cylindrical part of the locking pin can slide so that the door can be opened fully.

Zwischen Türblatt und Schließzapfen ist eine Rückstellfeder vorgesehen, die versucht, den ausgelenkten Handgriff in die Mittelstellung zu drücken. Eine weitere Rückstellfeder bewegt den Riegelschieber in die eine oder andere Nut des Schließzapfens. Diese Feder muß aber - zumindest bei einer Ausführungsform - so stark sein, daß sie in der Zwischenstellung den Riegelschieber auf dem Grund der zugehörigen Nut hält, daß also der Handgriff nicht selbsttätig in die Mittelstellung geht. Dann nämlich würde der Verschluß ohne Berührung des Handgriffes ganz öffnen.A return spring is provided between the door leaf and the locking pin, which tries the to push the deflected handle into the middle position. Another return spring moves the bolt slide into one or the other groove of the locking pin. That feather but must - at least in one embodiment - be so strong that it is in the Intermediate position holds the bolt slide on the bottom of the associated groove, that is the handle does not automatically go into the middle position. Then namely Open the lock fully without touching the handle.

Der beschriebene Türverschluß ist relativ aufwendig, weil er außer dem in der Tür zu lagernden Schließzapfen mit unterschiedlich ausgefrästen Nuten und einer Rückstellfeder einen teuren Schloßkasten benötigt, in dem der Riegelschieber leicht beweglich gegen die Kraft der genannten Feder verschiebbar gelagert werden muß.The door lock described is relatively expensive because it is in addition to that in the door stored locking pin with differently milled grooves and a return spring an expensive lock case needed, in which the bolt slide easily movable against the Force of the spring mentioned must be slidably mounted.

Der Verschluß ist aber auch störanfällig, weil sich der Schließzapfen und der Riegelschieber durch Reibung abnutzt. Falls die Scharniere oder sonstige Teile nachgeben, besteht die Gefahr des Verklemmens.The closure is also prone to failure, because the locking pin and the Latch slide worn due to friction. If the hinges or other parts give way, there is a risk of jamming.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, auf Dauer eine Reduzierung der Schließsicherheit zu vermeiden und einen besonders zuverlässigen und preiswerten ein- oder zweistufigen Türverschluß zu schaffen, der von seiner Konstruktion her größere Toleranzen an Tür und Gehäuse zuläßt.The invention has for its object a reduction in the long term Avoid locking security and a particularly reliable and inexpensive or to create two-stage door lock, the larger of its construction Allows tolerances on the door and housing.

Es ist weiterhin Aufgabe der Erfindung, die Montageschritte sehr einfach zu gestalten und die Einbauzeiten zu minimieren.It is also an object of the invention to make the assembly steps very simple and to minimize installation times.

Erfindungsgemäß gelingt dies dadurch, daß der Schließzapfen am Gerätegehäuse befestigt ist, daß das Riegelelement aus einem U-förmigen, federnden Bügel besteht, der so auf der im Türblatt gelagerten Welle eines Betätigungsgriffes aufgebaut ist, daß sein Quersteg federnd senkrecht zur Drehachse auslenkbar ist, und daß der Betätigungsgriff durch eine Feder in der Mittelstellung gehalten ist, aus der er so weit auslenkbar ist, daß der Quersteg des federnden Bügels auf eine achsparallele Fläche des Schließzapfens angehoben wird, wodurch sich die Tür öffnen läßt.According to the invention, this is achieved in that the locking pin is attached to the device housing is that the locking element consists of a U-shaped, resilient bracket, so on the built in the door leaf shaft of an operating handle that its crossbar is deflectable resiliently perpendicular to the axis of rotation, and that the actuating handle by a Spring is held in the central position, from which it can be deflected so far that the crossbar the resilient bracket is lifted onto an axially parallel surface of the locking pin, whereby the door can be opened.

Bei einem bevorzugten Ausführungsbeispiel ist der Schließzapfen so ausgebildet, daß sich zwei Schließstellungen ergeben. Die Tür kann mit einer Bewegung zugedrückt oder zugeschlagen werden, während die Öffnung zwangsläufig in zwei Stufen erfolgt. Bei Bewegung des Betätigungsgriffes im Uhrzeigersinn erfolgt eine Voröffnung, in der heiße Schwaden aus dem Gehäuse abziehen können. Der Griff bewegt sich sofort in die Mittelstellung zurück. Lenkt man ihn jetzt entgegen dem Uhrzeigersinn aus, wird der federnde Riegel ganz freigegeben und die Tür kann voll geöffnet werden.In a preferred embodiment, the locking pin is designed so that result in two closed positions. The door can be closed with one movement or be slammed, while the opening inevitably takes place in two stages. At Moving the operating handle clockwise results in a pre-opening in which hot Can pull vapors out of the housing. The handle immediately moves into the Middle position back. If you now deflect it counterclockwise, it becomes spring latch fully released and the door can be opened fully.

The right boundary of the locking recess 14d is an inclined surface 14d2.

Wenn die Tür zugedrückt wird, was ohne Benutzung des Betätigungsgriffes 1 stattfinden kann, bewegt sich die Rolle 8 unter Auslenkung des Federbügels 7 über die Fläche des Kegels 14a, bis sie in der Vertiefung 14d einrastet.If the door is closed, what will take place without using the operating handle 1 can, the roller 8 moves under deflection of the spring clip 7 over the surface of the Cone 14a until it snaps into the recess 14d.

Die Tür könnte in dieser Voröffnungsstufe stehen bleiben. In aller Regel drückt man jedoch so fest, daß die Rolle 8 über die schräge Fläche 14d2 läuft, um bei maximaler Pressung der Dichtung in die Rastvertiefung 14e zu gelangen.The door could stay in this pre-opening stage. As a rule, however, you press so tight that the roller 8 runs over the inclined surface 14d2 to at maximum pressure Seal to get into the recess 14e.

Für die Öffnung der Tür in zwei Stufen ist es ganz wichtig, daß der Schließzapfen 14 zwischen der ersten Rastvertiefung 14c und der zweiten Rastvertiefung 14d eine Zusatzausfräsung 14e erhält, die es als äquidistante Fläche auf versetztem Umfangswinkel ermöglicht, daß die Rolle 8 bei einer 45°-Drehung im Uhrzeigersinn von der ersten Sperrfläche 14c1 freikommt und von der zweiten Sperrfläche 14d1 aufgehalten wird. Anschließend bewegt sich der Betätigungsgriff 1 unter Kraft der Schenkelfeder 9 in die neutrale Mittelstellung, und die Rolle 8 liegt voll in der Rastvertiefung 14d. In dieser Phase kann das Gerät ablüften, d.h., Schwaden, Dampf oder Rauch können entweichen. Um die Tür ganz zu öffnen, muß jetzt der Betätigungsgriff entgegen dem Uhrzeigersinn bewegt werden.To open the door in two stages, it is very important that the locking pin 14 between the first locking recess 14c and the second locking recess 14d Additional milling 14e receives it as an equidistant surface on an offset circumferential angle Allows roller 8 to rotate clockwise 45 ° from the first Blocked area 14c1 is released and is held up by the second blocked area 14d1. Then the operating handle 1 moves under the force of the leg spring 9 in the neutral center position, and the roller 8 is fully in the locking recess 14d. In this phase can vent the device, i.e. swaths, steam or smoke can escape. To the To open the door fully, the operating handle must now be moved counterclockwise become.

Fig. 6b zeigt den Schließzapfen 14 von oben. Außer den Rastvertiefungen 14c und 14d sowie der Zusatzausfräsung 14e erkennt man eine weitere Zusatzausfräsung 14f, die es der Rolle 8 ermöglicht, bei entsprechender Verdrehung entgegen dem Uhrzeigersinn die Sperrfläche 14d1 zu überwinden.6b shows the locking pin 14 from above. Except the locking recesses 14c and 14d as well as the additional cutout 14e, one can see a further additional cutout 14f, which it is the Roll 8 allows, with a corresponding rotation counterclockwise To overcome the restricted area 14d1.

Fig. 6c stellt den Schließzapfen 14 in der Rückansicht dar. Man erkennt eine weitere Zusatzausfräsung 14g, die so gestaltet ist, daß die Rolle 8 nicht angehoben wird, wenn man zur Erzielung der Voröffnung den Betätigungsgriff entgegen dem Uhrzeigersinn, also in die falsche Richtung bewegt.Fig. 6c shows the locking pin 14 in the rear view. Another can be seen Additional milling 14g, which is designed so that the roller 8 is not raised when one to achieve the pre-opening the operating handle counterclockwise, i.e. in moving in the wrong direction.

Sowohl in der ersten als auch in der zweiten Öffnungsstufe bleibt eine Fehlbedienung ohne Folgen: Der Benutzer registriert den Fehlgriff und bewegt den Griff in die Gegenrichtung.In both the first and the second opening stage, incorrect operation remains without Consequences: The user registers the wrong grip and moves the grip in the opposite direction.

Das ganze System ist somit absolut narrensicher. Man kann die Tür zudrücken oder zuwerfen. Zur Türöffnung kann eine zusätzliche Feder vorgesehen sein, so daß die Öffnungsbewegung nach der vollständigen Entriegelung von selbst erfolgt.The whole system is absolutely foolproof. You can close the door or throwing. To open the door, an additional spring can be provided so that the Opening movement takes place automatically after complete unlocking.

Es ist auch nicht erforderlich, daß man den Betätigungsgriff 1 wirklich anfaßt. Er kann auch - wenn der Benutzer die Hände nicht frei hat - mit dem Ellenbogen bewegt werden.It is also not necessary to really touch the operating handle 1. He can also - if the user does not have his hands free - be moved with the elbow.

Fig. 7a zeigt den Federbügel 7 mit dem Quersteg 7a und der Rolle 8 von oben. Man erkennt, daß der im Grunde U-förmige Bügel aus Federdraht am rechten Ende in unterschiedlichen Abständen abgekantet ist. Die abgebogenen Enden 7b und 7c legen sich bei der Montage in die Aussparungen 4b und 4c (in Fig. 3 und 4). In dieser Position werden sie durch eine angedeutete Scheibe 15 und eine Schraube 16 gesichert.Fig. 7a shows the spring clip 7 with the cross bar 7a and the roller 8 from above. Man recognizes that the basically U-shaped spring wire bracket at the right end in bevelled at different distances. The bent ends 7b and 7c settle when mounting in the recesses 4b and 4c (in Fig. 3 and 4). Be in this position it secured by an indicated disc 15 and a screw 16.

Fig. 7b zeigt die Teile 7 und 8 von der Seite. Der kürzere Federschenkel 7d wird bei der Montage unter Vorspannung gesetzt. Die entspannte Stellung 8 (dünnere Linie) trägt das Zeichen 7d'.7b shows parts 7 and 8 from the side. The shorter spring leg 7d is used in the Assembly set under tension. The relaxed position 8 (thinner line) carries that Characters 7d '.

Fig. 7c zeigt den Federbügel 7 und die Rolle 8 von hinten gesehen in der vorgespannten Lage.Fig. 7c shows the spring clip 7 and the roller 8 seen from behind in the prestressed Location.

Gewerbliche VerwertbarkeitCommercial usability

Das beschriebene neuartige System zur ein- oder zweistufigen Verriegelung einer Tür ist außerordentlich einfach, schnell von einer Bauart in die andere umzurüsten und vor allem störunempfindlich. Da das Riegelelement aus einem einfachen Federbügel besteht, gibt es keine Gleitflächen, die durch Fettspuren oder dergl. verkleben könnten. Auch Toleranzen zwischen Tür und Gehäuse, die durch Abnutzung der Scharniere, Temperaturunterschiede oder Verkrustungen auftreten können, haben auf die Funktion nur wenig Einfluß. Falls die Türdichtungen altern und in ihrer Rückfedereigenschaft nachlassen sollte, kann der Schließzapfen mit Hilfe seiner Gewindestange leicht nachjustiert werden.The described novel system for one- or two-stage locking of a door is extremely easy, quick to change from one design to another and above all insensitive to interference. Since the locking element consists of a simple spring clip, there is no sliding surfaces that could stick due to traces of grease or the like. Tolerances too between door and housing caused by wear of the hinges, temperature differences or incrustations can have little effect on the function. if the Door seals should age and their springback properties should deteriorate The locking pin can be easily readjusted using its threaded rod.

Um eine Verdrehung des Schließzapfens bei der Montage oder Nachjustierung auszuschließen, kann es zweckmäßig sein, an der Gehäusezarge eine Anschlagfläche vorzusehen, die die Winkelstellung des Schließzapfens auf der den Rastvertiefüngen abgewandten Seite festlegtBy turning the locking pin during assembly or readjustment exclude, it may be appropriate to have a stop surface on the housing frame provide the angular position of the locking pin on the locking recesses side facing away

Der beschriebene Gerätetürverschluß ist hervorragend geeignet, vor allem in gewerblich genutzten Heißgeräten eingesetzt zu werden. The device door lock described is extremely suitable, especially in commercial used hot devices.
