Description

Die Erfindung betrifft eine Türverriegelungsvorrichtung mit den im Oberbegriff des Anspruches 1 genannten Merkmalen.The invention relates to a door locking device with the features mentioned in the preamble of claim 1.

Bei einer aus DE-OS 27 08 086 bekannten Türverriegelungsvorrichtung der eingangs genannten Art bildet in Zusammenbaustellung der Schloßplatfenrahmen eine Seitenwand des Gehäuses des Verriegelungsgerätes. Dabei ist die Schloßplatte weitgehend auf der Außenseite des Schloßplattenrahmens bzw. der Einheit zwischen Schloßplattenrahmen und Verriegelungsgerät geführt. Daher kann leicht Tropfwasser in das Innere des Verriegelungsgerätes gelangen, was gerade bei für Waschmaschinen bestimmten Türverriegelungsvorrichtungen zu befürchten ist. Außerdem ist bei der zusammengefügten Einheit von Schloßplattenrahmen und Verriegelungsgerät in deren Anlieferungszustand ein wichtiges Funktionsteil, nämlich der Riegelschieber, von außen zugänglich und beeinflußbar. Dadurch kann die bei der Herstellung vorgenommene Justierung der für die Funktion der Verriegelung wesentlichen Teile des Verriegelungsgerätes vor dessen Einbau in das Elektrogerät im Sinne einer Verstellung oder Beschädigung beeinflußt werden.In a door locking device known from DE-OS 27 08 086 of the type mentioned in the assembled position, the lock plate frame forms a side wall of the housing of the locking device. The lock plate is largely guided on the outside of the lock plate frame or the unit between the lock plate frame and locking device. Therefore, dripping water can easily get into the interior of the locking device, which is particularly to be feared with door locking devices intended for washing machines. In addition, an important functional part, namely the bolt slide, is accessible and can be influenced from the outside in the assembled unit of the lock plate frame and locking device in the condition in which they are delivered. As a result, the adjustment made during manufacture of the parts of the locking device that are essential for the function of the locking device can be influenced prior to its installation in the electrical device in the sense of adjustment or damage.

Der Erfindung liegt die Aufgabe zugrunde, eine Türverriegelungsvorrichtung der eingangs genannten Art so auszubilden, daß sie in einfacher Weise, jedoch definitiv justierbar und einbaufertig montierbar ist. Diese Aufgabe wird durch die Kennzeichnungsmerkmale des Anspruches 1 gelöst.The invention has for its object to provide a door locking device of the type mentioned so that it is simple, but definitely adjustable and ready to install. This object is achieved by the characterizing features of claim 1.

Durch die Erfindung sind alle für die Verriegelung der Schloßplatte in Schloßplattensperrstellung erforderlichen Funktionsteile in einem funktionsfähig fertigmontier- und einjustierbaren Verriegelungsgerät zusammengefaßt, welches in seine Funktionsstellung innerhalb des Schloßplattengehäuses lediglich nach Art einer Schublade eingeschoben zu werden braucht, wo es in seiner Sollstellung selbsttätig und ohne Spezialwerkzeuge unlösbar verrastet. Im Reparaturfalle läßt sich diese Verrastung jedoch einfach lösen. Ein defektes Verriegelungsgerät kann einfach durch ein Neues ausgetauscht werden. Schraubverbindungen sind zwischen Verriegelungsgerät und Schloßplattengehäuse nicht mehr erforderlich. Sowohl die schubladenartige Führung als auch die Verrastung halten das Verriegelungsgerät fest in seiner Sollstellung gegenüber der Schloßplatte. Das Schloßplattengehäuse und die Schloßplatte sind verhältnismäßig einfach gestaltbare Teile. Sie können hinsichtlich ihrer Ausgestaltung speziellen Kundenwünschen unschwer angepaßt werden, ohne daß die Gestaltung des Verriegelungsgerätes eine Abänderung erfahren muß. Dies ermöglicht einen hohen Standardisierungsgrad ohne Einbuße an Gestaltungsfreiheit für die Türverriegelungsvorrichtung. Bei der Anordnung der Schloßplatte zwischen einer Schloßplattengehäusewand und einer Seitenwand des Verriegelungsgerätes erfährt die Schloßplatte durch beide Wände zusätzlich eine Führung gegebenenfalls durch unmittelbare Anlage an diesen Wänden oder durch Anlage an aus den Wänden vorstehenden Anlagevorsprüngen. Besonders vorteilhaft ist dabei die Lösung nach dem Kennzeichnungsmerkmal des Anspruches 2.By the invention, all the functional parts required for locking the lock plate in the lock plate locking position are combined in a functional, fully assembled and adjustable locking device, which only needs to be inserted into its functional position within the lock plate housing in the manner of a drawer, where it is in its desired position automatically and without special tools permanently locked. In the event of repairs, however, this latching can easily be released. A defective locking device can easily be replaced by a new one. Screw connections between the locking device and the lock plate housing are no longer required. Both the drawer-like guide and the latching hold the locking device firmly in its target position in relation to the lock plate. The lock plate housing and the lock plate are relatively easy to design parts. With regard to their design, they can easily be adapted to special customer requirements without the locking device having to be modified. This enables a high degree of standardization without sacrificing design freedom for the door locking device. When the lock plate is arranged between a lock plate housing wall and a side wall of the locking device, the lock plate is additionally guided through both walls, possibly by direct contact with these walls or by contact with projecting projections projecting from the walls. The solution according to the characterizing feature of claim 2 is particularly advantageous.

Durch das Kennzeichnungsmerkmal des Anspruches 3, insbesondere in der Ausführungsform des Kennzeichnungsmerkmals des Anspruches 4 ist ein Tropfwasserschutz des Verriegelungsgerätes gegeben, ohne daß es einer zusätzlichen Abdichtung der Teilfuge zwischen der außenliegenden Wand des Verriegelungsgerätes und den Schloßplattengehäusewänden bedarf.The characterizing feature of claim 3, in particular in the embodiment of the characterizing feature of claim 4, provides drip protection of the locking device without requiring an additional sealing of the parting line between the outer wall of the locking device and the lock plate housing walls.

Durch das Kennzeichnungsmerkmal des Anspruches 5 nimmt die Schloßplatte innerhalb des Schloßplattengehäuses jeweils eine vorbestimmte Verschiebestellung ein. Dies sind eine mittlere Stellung, in der der Türschließhaken zum Schließen und Öffnen der Tür des Elektrogerätes ungehindert durch die Schließöffnung der Schloßplatte hindurchgeführt werden kann, sowie beidseitig von dieser Mittelstellung eine Verriegelungsstellung der Schloßplatte, in der eine Aussparung in der Schloßplatte in Überdeckung mit dem Riegelschieber des Verriegelungsgerätes steht, der nach dem Einschalten des Gerätestroms aufgrund der Auslenkung eines im Verriegelungsgerät angeordneten Bimetalls in die Schloßplattenaussparung eintaucht und damit deren Längsverschiebung sperrt. Die Anordnung jeweils einer beidseitig von der Öffnungsstellung vorgesehenen Verriegelungsstellung der Schloßplatte sowie die Anordnung je einer Schloßplattenaussparung für diese beiden Verriegelungsstellungen ermöglichen es, die Türverriegelungsvorrichtung in gleicher Weise ohne konstruktive Änderungen sowohl für einen nach links als auch für einen nach rechts in seine Schließstellung überführbaren Türschließhaken verwenden zu können, wie dies auch bei der eingangs genannten, bekannten Türverriegelungsvorrichtung vorgesehen und in der angegebenen Literaturstelle beschrieben ist.Due to the characterizing feature of claim 5, the lock plate takes a predetermined displacement position within the lock plate housing. These are a middle position in which the door locking hook for closing and opening the door of the electrical device can be passed unhindered through the locking opening of the lock plate, as well as a locking position of the lock plate on both sides of this middle position, in which a recess in the lock plate overlaps with the locking slide of the locking device, which, after switching on the device current, dips into the lock plate recess due to the deflection of a bimetal arranged in the locking device and thus blocks its longitudinal displacement. The arrangement of a locking position of the lock plate provided on both sides of the open position as well as the arrangement of a lock plate recess for these two locking positions make it possible to use the door locking device in the same way, without design changes, both for a door locking hook that can be moved into its closed position to the left and to the right to be able, as is also provided in the known door locking device mentioned at the outset and is described in the cited literature reference.

Eine konstruktiv besonders vorteilhafte Ausführungsform des Federrastgesperres ist in den Kennzeichnungsmerkmalen des Anspruches 6 niedergelegt. Durch das Kennzeichnungsmerkmal des Anspruches 7 wird eine besonders exakte Positionierung der Schloßplatte entweder in ihrer Öffnungsstellung oder in einer ihrer beiden Verriegelungsstellungen gewährleistet, womit in der Verriegelungsstellung auch für eine exakte Überdeckung des Riegelschiebers mit der Schloßplattenaussparung gesorgt ist. Eine gesonderte, auf die Schloßplatte einwirkende Rückstellfeder - wie beim eingangs geschilderten Stand der Technik - ist nicht erforderlich. Die wesentliche Verschiebebewegung der Schloßplatte aus ihrer Öffnungs- in die Verriegelungsstellung wird allein durch den Türschließhaken bewirkt, während ihre FeinPositionierung in einer der beiden Funktionsstellungen im Bedarfsfall durch das bzw. die Federrastgesperre vorgenommen wird. Die Kennzeichnungsmerkmale des Anspruches 8 betreffen eine besonders einfache und wirksame konstruktive Ausbildung des Federrastgesperres zwischen Schloßplatte und Schloßplattengehäuse.A structurally particularly advantageous embodiment of the spring catch is set out in the characterizing features of claim 6. The characterizing feature of claim 7 ensures a particularly exact positioning of the lock plate either in its open position or in one of its two locking positions, which in the locking position also ensures an exact overlap of the bolt slide with the lock plate recess. A separate return spring acting on the lock plate - as in the prior art described at the outset - is not required. The main movement of the lock plate from its opening in the The locking position is effected solely by the door locking hook, while its fine positioning in one of the two functional positions is carried out by the spring catch or locks if necessary. The characterizing features of claim 8 relate to a particularly simple and effective design of the spring catch between the lock plate and lock plate housing.

Durch das Kennzeichnungsmerkmal des Anspruches 9 sind die Funktionsteile des Verriegelungsgerätes zwischen seinem Boden und der Leiterplatte gegen mechanische Einflüsse von außen geschützt angeordnet, wobei gegen seitlichen Eingriff in den Zwischenraum zwischen diesen beiden Abdeckungen zusätzlich die Außenwand des Verriegelungsgerätes einen Schutz darstellt.By the characterizing feature of claim 9, the functional parts of the locking device between its bottom and the circuit board are arranged protected against mechanical influences from the outside, the outer wall of the locking device also providing protection against lateral engagement in the space between these two covers.

Das Kennzeichnungsmerkmal des Anspruches 10 dient zur Sicherstellung der genauen Positionierung des Verriegelungsgerätes in Einschubstellung innerhalb des Schloßplattengehäuses gemeinsam mit den Verrastungsmitteln. Die Verrastungsmittel halten dabei die Verriegelungsvorrichtung lediglich in Einschubstellung, während die sonstige Positionierung des Verriegelungsgerätes innerhalb des Schloßplattengehäuses durch die schubladenartigen Führungsmittel gewährleistet wird.The characteristic of claim 10 serves to ensure the exact positioning of the locking device in the inserted position within the lock plate housing together with the locking means. The locking means keep the locking device only in the inserted position, while the other positioning of the locking device within the lock plate housing is ensured by the drawer-like guide means.

Durch das Kennzeichnungsmerkmal des Anspruches 11 kann die gesamte Türverriegelungsvorrichtung in einfacher Weise an Elektrogeräten befestigt werden.Due to the characterizing feature of claim 11, the entire door locking device can be attached to electrical appliances in a simple manner.

Der Gegenstand der Erfindung wird anhand der Figuren beispielsweise erläutert. Es zeigen:

  • Fig. 1 eine Draufsicht auf eine erfindungsgemäß ausgebildete, fertigmontierte Türverriegelungsvorrichtung.
  • Fig. 2 eine Draufsicht analog Fig. 1 auf das in das Schloßplattengehäuse der Türverriegelungsvorrichtung einzusetzende Verriegelungsgerät.
  • Fig. 3 und 4 in logischer Zuordnung zueinander eine perspektivische Ansicht des mit der eingesetzten Schloßplatte versehenen Schloßplattengehäuses und des Verriegelungsgerätes in gegenüber dem Schloßplattengehäuse einschubbereiter Ausgangsstellung, wobei das Schloßplattengehäuse teilweise herausgebrochen gezeichnet ist.

The object of the invention is explained for example with reference to the figures. Show it:
  • Fig. 1 is a plan view of a fully assembled door locking device designed according to the invention.
  • Fig. 2 is a plan view analogous to FIG. 1 of the locking device to be inserted into the lock plate housing of the door locking device.
  • 3 and 4 in logical correspondence to one another a perspective view of the lock plate housing provided with the inserted lock plate and of the locking device in a position ready for insertion relative to the lock plate housing, the lock plate housing being shown partly broken away.
  • Fig. 5 is a plan view of the locking device with the circuit board removed.
  • Fig. 6 is a side view of the locking device in the direction of arrow VI in Fig. 2 and Fig. 5 with attached circuit board.

Die Türverriegelungsvorrichtung wird auch zur Verriegelung von Verschlüssen und Abdeckungen, insbesondere aber für Waschmaschinentüren verwendet. Sie soll sicherstellen, daß das Elektrogerät erst und nur dann in Betrieb gesetzt werden kann, wenn eine vorschriftsmäßige Türverriegelung vorliegt. Dabei wird für die Dauer des Betriebes die Tür verriegelt gehalten. Es ist also eine Türöffnung bei aufrechterhaltener Einschaltung des Elektrogerätes nicht möglich.The door locking device is also used for locking locks and covers, but especially for washing machine doors. It is intended to ensure that the electrical device can only be put into operation if the door lock is in accordance with regulations. The door is kept locked for the duration of operation. It is therefore not possible to open the door while the electrical device is switched on.

Die Türverriegelungsvorrichtung enthält eine Schloßplatte 1, die innerhalb des Schloßplattengehäuses 2 in Pfeilrichtung 3 längsverschiebbar gelagert ist. Die Längsverschiebebewegung der Schloßplatte 1 ist durch einen nicht dargestellten, mit der zu verriegelnden Tür verbundenen, die am Schloßplattenende 4 angeordnete Schließöffnung 5 durchgreifenden Türschließhaken steuerbar, wie dies prinzipiell in DE-OS 27 08 086 beschrieben ist.The door locking device contains a lock plate 1, which is mounted within the lock plate housing 2 in the direction of arrow 3 to be longitudinally displaceable. The longitudinal displacement movement of the lock plate 1 can be controlled by a door lock hook, not shown, connected to the door to be locked and penetrating through the lock opening 5 arranged at the lock plate end 4, as described in principle in DE-OS 27 08 086.

Weiterhin enthält die Türverriegelungsvorrichtung ein Verriegelungsgerät 6, das einen in Schloßplattensperrstellung in eine der beiden Schloßplattenaussparungen 7 bewegungssperrend einführbaren Riegelschieber 8 aufweist. Es sind zwei voneinander beabstandete Schloßplattenaussparungen 7 vorhanden, um die Türverriegelungsvorrichtung in gleicher Weise für links- oder rechtsschließende Türschließhaken verwenden zu können, wie dies in DE-OS 27 08 086 insbesondere anhand von dort Fig. 1 im einzelnen erläutert ist. Die Einführbewegung des Riegelschiebers 8 ist durch den Einschaltstrom des Elektrogerätes gesteuert, wie dies weiter unten im einzelnen noch erläutert wird.Furthermore, the door locking device contains a locking device 6, which has a locking slide 8 which can be inserted in a locking manner in one of the two locking plate recesses 7 in the locking position of the locking plate. There are two spaced-apart lock plate recesses 7 in order to be able to use the door locking device in the same way for left- or right-closing door locking hooks, as is explained in detail in DE-OS 27 08 086, in particular with reference to FIG. 1 there. The insertion movement of the locking slide 8 is controlled by the inrush current of the electrical device, as will be explained in more detail below.

Die Führung der Schloßplatte 1 außerhalb des Verschiebebereiches der Schließöffnung 5 der Schloßplatte 1 erfolgt in einem lediglich nach einer Seite (öffnung 9) offenen Schloßplattengehäuse 2. Das Verriegelungsgerät 6 ist schubladenartig in die Öffnung 9 des Gehäuses 1 einschiebbar und dort in Einschubstellung verrastbar. Zur Verrastung weist die Außenwand 10 des Verriegelungsgerätes 6 an ihrer Ober- und Unterseite Verriegelungsvorsprünge 11 auf, die in Einschubendstellung in Verriegelungsausnehmungen 12 einfallen, die in die entsprechenden Seitenwände des Schloßplattengehäuses 2 eingebracht sind. In verrasteter Einschubendstellung und entsprechender Verschiebestellung der Schloßplatte 1 in Pfeilrichtung 3 fluchtet der Riegelschieber 8 mit einer der Schloßplattenaussparungen 7. Zur Gewährleistung der schubladenartigen Führung des Verriegelungsgerätes 6 ist dessen Bodenplatte 13 an ihren Seiten mit jeweils einer Führungsrippe 14 oder einer Führungsnut versehen, die mit entsprechenden, an die Innenseiten der Gehäuseseitenwände 15,16 angeformten Führungsrippen 17 bzw. einer Führungsnut 18 zusammenwirken. Die Schloßplatte 1 liegt zwischen der den Gehäuseboden bildenden Schloßplattengehäusewand 19 und der Bodenplatte 13 des Verriegelungsgerätes 6. Die vorzugsweise als Flachstecker 20-22 ausgebildeten Stromanschlüsse des Verriegelungsgerätes 6 sind aus dessen in Einschubstellung die Offenseite (Öffnung 9) des Schloßplattengehäuses 2 verschließender Außenwand 10 herausgeführt. Das Verriegelungsgerät 6 ist in Einschubstellung mit seiner vom Riegelschieber 8 durchsetzten Bodenplatte 13 der Schloßplatte 1 zugewandt und dabei parallel zur Schloßplattenebene ausgerichtet. Die Offenseite (Öffnung 9) des Schloßplattengehäuses 2 verläuft etwa rechtwinklig zur Schloßplattenebene und weist in Einbaustellung nach unten. Dadurch ist das in Einbaustellung befindliche Verriegelungsgerät 6 ohne weitere Abdichtmaßnahmen tropfwassergeschützt. Dieser Tropfwasserschutz ist besonders dadurch wirksam, wenn die Außenwand 10 des Verriegelungsgerätes 6 in die Öffnung 9 des Schloßplattengehäuses 2 eingelassen bzw. in dieser versenkt angeordnet ist.The lock plate 1 is guided outside the sliding area of the lock opening 5 of the lock plate 1 in a lock plate housing 2 which is only open to one side (opening 9). The locking device 6 can be inserted like a drawer into the opening 9 of the housing 1 and locked there in the inserted position. For latching, the outer wall 10 of the locking device 6 has on its upper and lower side locking projections 11 which, in the inserted end position, engage in locking recesses 12 which are introduced into the corresponding side walls of the lock plate housing 2. In the latched insertion end position and corresponding displacement position of the lock plate 1 in the direction of the arrow 3, the locking slide 8 is aligned with one of the lock plate recesses 7. To ensure the drawer-like guidance of the locking device 6, the bottom plate 13 is provided on its sides with a guide rib 14 or a guide groove, which with corresponding , on the inside of the housing side walls 15, 16 integrally formed guide ribs 17 or a guide groove 18. The lock plate 1 lies between the lock plate housing wall 19 forming the housing base and the base plate 13 of the locking device 6. The power connections of the Locking device 6 are led out of the outer wall 10 closing the open side (opening 9) of the lock plate housing 2 in the inserted position. In the inserted position, the locking device 6 faces the lock plate 1 with its bottom plate 13 penetrated by the locking slide 8 and is aligned parallel to the lock plate level. The open side (opening 9) of the lock plate housing 2 extends approximately at right angles to the lock plate level and points downward in the installed position. As a result, the locking device 6 in the installed position is protected against dripping water without further sealing measures. This drip water protection is particularly effective when the outer wall 10 of the locking device 6 is inserted into the opening 9 of the lock plate housing 2 or is sunk therein.

Der innerhalb des Schloßplattengehäuses 2 liegende Teil der Schloßplatte 1, d.h. das gehäuseseitige Schloßplattenende 23, ist U-förmig ausgebildet. Die Außenflanken 24, 25 des gehäuseseitigen Schloßplattenendes 23 sind Teil jeweils eines Schenkels 26 bzw. 27. Dadurch sind die Schenkel 26, 27 in der Schloßplattenebene rechtwinklig zur Pfeilrichtung 3 einfederbar. Die beiden Flanken 24, 25 sind jeweils mit drei Rastausnehmun-gen 28-30 versehen, die jeweils mit einem einstückig mit dem aus Kunststoff gefertigten Schloßplattengehäuse 2 gespritzten Gehäusevorsprung 31 bzw. 32 zusammenwirken. Die Gehäusevorsprünge 31, 32 stehen aus der parallel zur Schloßplatte 1 verlaufenden Schloßplattengehäusewand 19 vor. Ihre Form stellt ein Negativ zu den spitzwinkligen, einander gegenüberliegenden Rastausnehmungen 28-30 dar.The part of the lock plate 1 lying within the lock plate housing 2, i.e. the lock plate end 23 on the housing is U-shaped. The outer flanks 24, 25 of the lock plate end 23 on the housing side are part of a leg 26 and 27, respectively. As a result, the legs 26, 27 can be deflected in the lock plate plane at right angles to the direction of the arrow 3. The two flanks 24, 25 are each provided with three locking recesses 28-30, each of which cooperate with a housing projection 31 or 32 which is injection-molded in one piece with the lock plate housing 2 made of plastic. The housing projections 31, 32 protrude from the lock plate housing wall 19 running parallel to the lock plate 1. Their shape is a negative for the acute-angled, opposite recesses 28-30.

Bei in den einander gegenüberliegenden Rastausnehmungen 29 einliegenden Gehäusevorsprüngen 31 bzw. 32 befindet sich die Schloßplatte 1 in ihrer Öffnungsstellung, in der der Türschließhaken unbehindert betätigt, d.h. in die Schließöffnung 5 ein- und ausgeführt werden kann (Fig. 3). Wird zur Türschließung ein - mit Bezug auf Fig. 3 - linksschließender Türschließhaken verwendet und dieser in seine Türschließstellung überführt, so wird die Schloßplatte 1 in Pfeilrichtung 3 nach links verschoben. Dabei federn die U-Schenkel 26, 27 der Schloßplatte 1 nach innen. Die Gehäusevorsprünge 31, 32 gleiten dabei aus den Rastausnehmungen 29 hinaus und fallen in die Rastausnehmungen 28 ein. Durch den Spreizdruck der U-Schenkel 26, 27 wird dafür gesorgt, daß die Gehäusevorsprünge 31, 32 satt in den Rastausnehmungen 28 einliegen, so daß in jedem Falle die Schloßplatte 1 eine Stellung einnimmt, in der ihre rechte Schloßplattenaussparung 7 in Überdeckungsstellung mit dem Riegelschieber 8 des Verriegelungsgerätes steht. Bei Verwendung eines - bezogen auf Fig. 3 - rechtsschließenden Türhakens fallen mit der Schließbewegung der Schloßplatte 1 die Gehäusevorsprünge 31, 32 in die Rastausnehmungen 30 der Schloßplatte 1 ein und bringen dadurch selbsttätig die linke Schloßplattenaussparung 7 in Überdeckungsstellung mit dem Riegelschieber 8.With the housing projections 31 and 32 lying in the mutually opposite latching recesses 29, the lock plate 1 is in its open position, in which the door locking hook is operated without hindrance, i.e. can be inserted and executed in the closing opening 5 (FIG. 3). If a door locking hook which closes to the left is used for the door closure and is transferred to its door closing position, the lock plate 1 is shifted to the left in the direction of the arrow 3. The U-legs 26, 27 of the lock plate 1 spring inwards. The housing projections 31, 32 slide out of the locking recesses 29 and fall into the locking recesses 28. The spreading pressure of the U-legs 26, 27 ensures that the housing projections 31, 32 lie snugly in the latching recesses 28, so that in each case the lock plate 1 assumes a position in which its right lock plate recess 7 is in the overlapping position with the locking slide 8 of the locking device is. When using a door hook which closes to the right in relation to FIG. 3, with the closing movement of the lock plate 1, the housing projections 31, 32 fall into the locking recesses 30 of the lock plate 1 and thereby automatically bring the left lock plate recess 7 into overlap position with the locking slide 8.

Die Einzelteile des Steuermechanismus für den Riegelschieber 8 sind insbesondere in Fig. 7 deutlich dargestellt. Auf die aus Kunststoff gespritzte Bodenplatte 13 sind die Einzelteile der Steuereinrichtung aufmontiert. Der Bimetallanschluß 38 wird mit seinem Flachstecker 22 durch den Schlitz 40 der mit der Bodenplatte 13 einstückig gespritzten Außenwand 10 hindurchgesteckt und mittels einer Rohrniete 41 mit der Bodenplatte 13 vernietet. In den Zwischenraum zwischen den Schenkeln des U-förmigen Lappens 42 des Bimetallanschlusses 38 ist das Bimetall 43 eingelegt und verschweißt. Die Justierschraube 44 steckt in der Gewindebohrung 45 des Bimetallanschlusses 38. Ihr Kegel 46 drückt gegen die Nase 47 des Bimetalls 43 und beeinflußt damit dessen Vorspannung. Die Beheizung des Bimetalls 43 erfolgt durch den PTC Widerstand 48, der rund oder eckig ausgebildet sei kann. Der PTC-Widerstand 48 wird durch die Feder 49 an das Bimetall 43 gepreßt. Für die Aufnahme des PTC-Widerstandes 48 ist die Feder 49 speziell ausgemuldet (Ausmuldung 39). Das zur Ausmuldung 39 entgegengesetzte Ende 37 der Feder 49 ist an den elektrischen Heizungsanschluß 50 angeschweißt, der unmittelbar mit dem Flachstecker 21 verbunden ist. Der Flachstecker 21 ist durch den Schlitz 51 in der Außenwand 10 des Verriegelungsgerätes 6 hindurchgesteckt. Der Winkel 53 ist nach dem Einbau unter den aus der Bodenplatte 13 vorstehenden Haken 54 geschoben, der die Bewegung des Heizungs-Anschlusses 15 nach oben verhindert. Der endgültige Festsitz des Heizungsanschlusses 50 im Verriegelungsgerät 6 wird in nachstehend noch näher erläuterter Weise durch die Leiterplatte 55 sichergestellt.The individual parts of the control mechanism for the locking slide 8 are clearly shown in particular in FIG. 7. The individual parts of the control device are mounted on the base plate 13 molded from plastic. The bimetallic connector 38 is inserted with its flat plug 22 through the slot 40 of the outer wall 10 molded integrally with the base plate 13 and riveted to the base plate 13 by means of a tubular rivet 41. The bimetal 43 is inserted and welded into the space between the legs of the U-shaped tab 42 of the bimetal connector 38. The adjusting screw 44 is in the threaded bore 45 of the bimetal connection 38. Its cone 46 presses against the nose 47 of the bimetal 43 and thus influences its pretension. The bimetal 43 is heated by the PTC resistor 48, which can be round or angular. The PTC resistor 48 is pressed against the bimetal 43 by the spring 49. The spring 49 is specially hollowed out to accommodate the PTC resistor 48 (hollow 39). The end 37 of the spring 49 opposite the hollow 39 is welded to the electrical heating connection 50, which is connected directly to the flat plug 21. The tab 21 is inserted through the slot 51 in the outer wall 10 of the locking device 6. After installation, the angle 53 is pushed under the hook 54 protruding from the base plate 13, which prevents the heating connection 15 from moving upward. The final tight fit of the heating connection 50 in the locking device 6 is ensured in the manner explained in more detail below by the printed circuit board 55.

Die Kontaktfeder 56 ist mit ihren Schultern 57 in die Schlitze 58 des Bimetallanschlusses 38 eingehängt und durch die Kippfeder 59 auf Spannung gebracht. Die Kippfeder 59 stützt sich an der Nase 60 des Bimetalls 43 und dem Ansatz 61 der Kontaktfeder 56 ab.The contact spring 56 is suspended with its shoulders 57 in the slots 58 of the bimetallic connection 38 and brought into tension by the toggle spring 59. The tilt spring 59 is supported on the nose 60 of the bimetal 43 and the shoulder 61 of the contact spring 56.

In die Bohrung 62 der Kontaktfeder 56 ist der Kontaktniet 63 eingenietet, der mit dem ebenfalls durch einen Kontaktniet gebildeten Festkontakt 64 zusammenwirkt. Der Festkontakt 64 ist auf den Kontaktanschluß 65 aufgenietet, der mit dem Flachstecker 20 verbunden ist. Der Flachstecker 20 ist zu seiner Befestigung durch den Schlitz 67 in der Außenwand 10 hindurchgesteckt. Dabei liegt sein Winkel 68 unter dem Haken 69 der Bodenplatte 13. Der endgültige Festsitz des Kontaktanschlusses 65 wird ebenfalls durch die Leiterplatte 55 bewirkt.The contact rivet 63 is riveted into the bore 62 of the contact spring 56 and interacts with the fixed contact 64, which is also formed by a contact rivet. The fixed contact 64 is riveted onto the contact terminal 65, which is connected to the flat plug 20. The flat plug 20 is inserted through the slot 67 in the outer wall 10 for its attachment. Its angle 68 is below the hook 69 of the base plate 13. The final tight fit of the contact terminal 65 is also effected by the circuit board 55.

Der Riegelschieber 8 ist auf die Nase 70 der Kontaktfeder 56 aufgeschoben. Die hierzu die schlitzartige Ausnehmung 71 des Riegelschiebers 8 durchsetzende Nase 70 der Kontaktfeder 56 ist an deren Freiende angeordnet. Die Führung des Riegelschiebers 8 in der Bodenplatte 13 wird durch die Ausnehmung 72 der Bodenplatte 13 besorgt.The locking slide 8 is pushed onto the nose 70 of the contact spring 56. The nose 70 of the contact spring 56 penetrating the slot-like recess 71 of the locking slide 8 is arranged at the free end thereof. The guidance of the locking slide 8 in the base plate 13 is worried by the recess 72 of the bottom plate 13.

Von dem Bimetallanschluß 38, dem Heizungsanschluß 50 und dem Kontaktanschluß 65 stehen jeweils Anschlußnasen 73 nach oben, die entsprechende Ausnehmungen 74 der Leiterplatte 55 durchsetzen. Auf der Leiterplatte 55 sind gedruckte Verbindungen 76 aufgebracht, die mit den entsprechenden Anschlußnasen 73 verlötet sind. Hierdurch werden zunächst die Anschlüsse 38, 50 und 65 festgelegt. Die Verbindungen 76 laufen in eine Lasche 77 der Leiterplatte 55 aus, die als Kompakt-Steckverbinder wie die Flachstecker 20-22 über die Außenwand 10 des Verriegelungsgerätes 6 vorsteht.From the bimetallic connection 38, the heating connection 50 and the contact connection 65, there are connection lugs 73 which pass through corresponding recesses 74 in the printed circuit board 55. Printed connections 76 are applied to the circuit board 55 and are soldered to the corresponding connection lugs 73. In this way, the connections 38, 50 and 65 are initially defined. The connections 76 run into a tab 77 of the printed circuit board 55, which projects as a compact connector like the flat plug 20-22 over the outer wall 10 of the locking device 6.

An das Schloßplattengehäuse 2 ist eine in Richtung auf das Schließende der Schloßplatte 1 vorstehende Führungsplatte 78 angeformt. Die Führungsplatte 78 trägt beidseitig der Schloßplattenführung Befestigungsbohrungen 79 für die Türverriegelungsvorrichtung.A guide plate 78 protruding toward the closing end of the lock plate 1 is molded onto the lock plate housing 2. The guide plate 78 carries mounting holes 79 for the door locking device on both sides of the lock plate guide.

Die Türverriegelungsvorrichtung arbeitet wie folgt: Mit der Verriegelungsbewegung des Türschließhakens wird die Schloßplatte 1 in ihre Schließstellung überführt. Nunmehr wird an die Flachstecker 21 und 22 die Betriebsspannung des Elektrogerätes von z.B. 220 V angelegt. Daraufhin erhitzt sich der PTC-Widerstand und das Bimetall 43 wird nach oben ausgedehnt (Fig. 6). Nach Überwindung der Totpunktlage der Kippfeder 59 schnappt die Kontaktfeder 56 nach unten, schließt die Kontakte 63, 64 und bewegt gleichzeitig den Riegelschieber 8 sperrend in die mit ihm in Überdeckungsstellung befindliche Schloßplattenaussparung 7. Erst dadurch wird das Elektrogerät an die Betriebsspannung gelegt.The door locking device works as follows: With the locking movement of the door locking hook, the lock plate 1 is transferred into its closed position. Now the operating voltage of the electrical device of e.g. 220 V applied. The PTC resistor then heats up and the bimetal 43 is expanded upward (FIG. 6). After overcoming the dead center position of the toggle spring 59, the contact spring 56 snaps down, closes the contacts 63, 64 and at the same time moves the locking slide 8 into the locking plate recess 7 which is in the overlapping position with it. Only then is the electrical device connected to the operating voltage.
