Description
Deckelverschluß für Druckkochtöpfe-und ähnliche Behälter Die Erfindung betrifft einen Deckelverschluß für Druckkochtöpfe und ähnliche Behälter, bei welchem in bekannter Weise ein Druckbügel unter Zwischenschaltung einer oder mehrerer Federn, vorzugsweise Schraubenfedern, auf den Deckel derart wirkt, daß er ihn entgegen dem Öffnungsbestreben des Innendruckes des Behälters so lange geschlossen hält, bis dieser Druck auf einen die Federkraft überwindenden Wert gestiegen ist, bei dem ein Anheben des Deckels und ein Entweichen des Lberschußdampfes stattfindet. Es sind auch schon Verschlüsse bekannt geworden, bei denen der Druckbügel selbst federnd ausgebildet ist.Lid closure for pressure cookers and similar containers The invention relates to a lid closure for pressure cookers and similar containers in which in a known way a pressure bracket with the interposition of one or more springs, preferably coil springs, acts on the cover in such a way that it counteracts it Efforts to open the internal pressure of the container keeps closed until this pressure has risen to a value which overcomes the spring force, at which the lid is raised and the excess steam escapes. It closures have also become known in which the pressure bracket itself is resilient is trained.
Erfindungsgemäß wird bei einem solchen Deckelverschluß zum Festhalten des Dekkels in der Schließlage eine aus gegeneinander beweglichen, durch Federn zusammengehaltenen Teilen bestehende Querstange verwendet, bei der die dem Innendruck des Behälters entgegenwirkende Federkraft eine den Deckel geschlossen haltende gegenseitige Stellung der Stangenteile bewirkt, ein diese Federkraft überschreitender Behälterinnendruck dagegen ein Anheben des Deckels und damit ein Durchknicken der Querstange durchüberführen der Stangenteile in eine andere gegenseitige Stellung hervorruft.According to the invention, such a lid lock is used to hold on of the cover in the closed position one made of mutually movable by springs parts held together using existing crossbars, in which the internal pressure of the container counteracting spring force a mutual holding the lid closed Position of the rod parts causes an internal pressure in the container that exceeds this spring force on the other hand, carry out a lifting of the cover and thus a buckling of the crossbar the rod parts in a different mutual position.
Die Zeichnung zeigt den Deckelverschluß nach der Erfindung in einem Ausführungsbeispiel. Der Deckel z des Druckkochtopfes i wird durch eine Querstange 4. geschlossen gehalten, deren eines Ende in das Loch einer am Topf befestigten Öse 5 eingeführt ist, während das andere Querstangenende in das Auge eines um den Zapfen 7 schwenkbaren Bolzens 6 eingreift, der eine Druckschraube 8 trägt. Die Querstange 4. setzt sich aus zwei Teilen 4' und 4" zusammen, die sich mit ebenen Endflächen aneinanderlegen und mit den unteren Vorsprüngen 9 in einer Höhlung g' des Deckels ruhen. An der Oberseite gehen die Stangenteile 4', 4" in zwei hochstehende Arme i o über, welche ein Bolzen i i durchsetzt, den zwei geeichte Schraubenfedern 12 umschließen. Die Arme i o werden durch die Federn 12, deren Achsen mit der Deckelkante praktisch gleichlaufen, fest gegeneinandergedrückt, so daß die Stangenteile ¢', 4" ein starres Ganzes bilden und im Zusammenwirken mit der Druckschraube 6 den Dekkel 2 geschlossen halten.The drawing shows the lid closure according to the invention in one Embodiment. The lid z of the pressure cooker i is held by a cross bar 4. kept closed, one end of which is attached to the hole in the pot Eyelet 5 is inserted, while the other end of the crossbar in the eye of one around the Pin 7 pivotable bolt 6 engages, which carries a pressure screw 8. The crossbar 4. is made up of two parts 4 'and 4 ", which have flat end faces put together and with the lower projections 9 in a cavity g 'of the lid rest. At the top, the rod parts 4 ', 4 "go into two upright arms i o over which a bolt i i penetrates, the two calibrated coil springs 12 enclose. The arms i o are supported by the springs 12, the axes of which are connected to the edge of the cover run practically the same, pressed firmly against each other so that the rod parts ¢ ', 4 "form a rigid whole and, in cooperation with the pressure screw 6, the lid Keep 2 closed.
Wird im Topf i ein Druck erzeugt, der den Deckel emporzuheben strebt, so verhindert die Querstange 4 dieses Emporheben, solange die Dampfwirkung von den einer Lagenänderung der Teile der Querstange 1. entgegenwirkenden Federn 12 überwunden wird. Erreicht dagegen der Dampfdruck einen die Federkraft übersteigenden Wert, so hebt sich der Deckel, wobei der von ihm auf die Vorsprünge 9 ausgeübte Druck die Stangenteile 4', ¢" um einen bestimmten Winkel um ihre Stützpunkte in den öffnungen der öse 5 und des Bolzens G .schwenkt und die Arme i o entgegen der Wirkung der Federn 12 auseinanderbewegt. Der Decke12 kann infolge dieser Formänderung der Querstange 4 als Sicherheitsventil wirken, während beim Aufhören des Überdruckes im Topf die Federn 12 die Arme i o wieder aneinanderdrücken und dadurch den Deckel wieder von neuem schließen.If a pressure is generated in the pot i, which tends to lift the lid, so the crossbar 4 prevents this uplifting, as long as the steam effect of the a change in position of the parts of the crossbar 1. counteracting springs 12 overcome will. If, on the other hand, the steam pressure reaches a value that exceeds the spring force, so the lid rises, with that of it on the projections 9 exerted pressure on the rod parts 4 ', ¢ "at a certain angle around their support points swivels in the openings of the eyelet 5 and of the bolt G and the arms i o in the opposite direction the action of the springs 12 moved apart. The ceiling 12 can as a result of this change in shape the cross rod 4 act as a safety valve, while when the overpressure ceases in the pot the springs 12 press the arms together again and thereby the lid close again.
Die auf die Querstange wirkenden Federn können statt mit praktisch zum Deckel gleichlaufender Achse auch mit einer anderen Achsrichtung angeordnet sein. Ferner kann die Querstange statt zweiteilig auch mehrteilig ausgeführt werden.The springs acting on the crossbar can be practical instead of using also arranged with a different axis direction to the cover of the co-rotating axis be. Furthermore, the crossbar can also be made in several parts instead of in two parts.
