Description

Vorreiberverschluß cam lock
B e s c h r e i b u n gDescription
Die Erfindung betrifft einen Vorreiberverschluß, insbesondere zum Einsatz an einer dünnwandigen Tür insbesondere von Schaltschränken, mit einem die Tür in einer zugeordneten Öffnung durchgreifenden und an der Tür mittels eines sich daran abstützenden Gehäusekopfes festlegbaren Gehäuse, einer im Inneren des Gehäuses drehbar angeordneten Betätigung sowie einer mit der Betätigung verbundenen Verriegelungszunge, wobei dem Vorreiberverschluß eine bei der Montage an der Tür zwischen dem Gehäusekopf und der Tür einzulegende Außendichtung zur radialen Abdichtung des Türdurchbruches zugeordnet und im Inneren des Gehäuses eine Innendichtung zur Abdichtung der Betätigung gegen das Gehäuse angeordnet ist. Ein derartiger Vorreiberverschluß ist in der DE-C2-33 16 834 beschrieben. Bei dem bekannten Vorreiberverschluß ist die Betätigung in das Gehäuse von dem auf der Türaußenseite anzuordnenden Gehäusekopf des Gehäuses her eingesetzt und stützt sich im Inneren des Gehäuses über eine entsprechend ausgebildete Schulter gegen eine weitere axiale Verschiebung im Gehäuse ab; auf einen über das Gehäuse innenseitig überragenden Ansatz der Betätigung ist in formschlüssiger Verbindung damit eine Verriegelungszunge aufgesetzt und an der Betätigung durch eine axial in die Betätigung eingeschraubte Schraube befestigt. Zusätzlich ist zwischen Gehäuse und Betätigung noch eine Wellscheibe unter anderem zum Toleranzausgleich angeordnet. Zur Abdichtung des Vorreibergehäuses ist zunächst eine an der Unterseite des Gehäusekopfes bei der Montage anzubringende und damit die radiale Abdichtung des Türdurchbruchs gegen den Vorreiberverschluß übernehmende Äußendichtung erforderlich^ wobei im Inneren des Gehäuses zusätzlich zur Abdichtung des Gehäuses gegen die darin drehbare Betätigung eine Innendichtung eingelegt ist.The invention relates to a cam lock, in particular for use on a thin-walled door, in particular of control cabinets, with a housing which penetrates the door in an associated opening and can be fixed on the door by means of a housing head which is supported thereon, an actuation which is rotatably arranged in the interior of the housing and also with the actuation connected locking tongue, the cam lock is assigned an outer seal to be inserted during assembly on the door between the housing head and the door for radial sealing of the door opening and an inner seal for sealing the actuation against the housing is arranged inside the housing. Such a cam lock is described in DE-C2-33 16 834. In the known cam lock, the actuation is inserted into the housing from the housing head of the housing to be arranged on the outside of the door and is supported in the interior of the housing against a further axial displacement in the housing via a suitably designed shoulder; a locking tongue is thus placed in a positive connection on a projection of the actuation projecting over the inside of the housing and fastened to the actuation by a screw axially screwed into the actuation. In addition, a corrugated washer is arranged between housing and actuation, among other things, for tolerance compensation. To seal the sash housing, an outer seal that is to be attached to the underside of the housing head during assembly and thus takes over the radial sealing of the door opening against the sash lock is required ^ whereby an inner seal is inserted in the interior of the housing in addition to the sealing of the housing against the actuation that can be rotated therein.
Mit dem bekannten Vorreiberverschluß ist der Nachteil verbunden, daß die einzelnen Bauteile des Vorreiberverschlusses wie Gehäuse. Betätigung, Verriegelungszunge, Befestigungsschraube sowie Innendichtung und Außendichtung in jeweils eigenständigen Produktionsschritten hergestellt und vorrätig gehalten werden müssen, und daß es zur Herstellung eines einzelnen Vorreiberverschlusses einer gesonderten Montage der mehreren Einzelteile miteinander bedarf. Der Erfindung liegt daher die Aufgabe zugrunde, einen Vorreiberverschluß mit den eingangs genannten Merkmalen zur Verfügung zu stellen, der einfach und damit zu geringen Kosten herstellbar ist.The disadvantage of the known cam lock is that the individual components of the cam lock, such as the housing. Actuation, locking tongue, fastening screw and inner seal and outer seal each have to be produced in separate production steps and kept in stock, and that a separate assembly of the several individual parts is required to produce a single sash lock. The invention is therefore based on the object of providing a cam lock with the features mentioned at the outset, which can be produced simply and therefore at low cost.
Die Lösung dieser Aufgabe ergibt sich einschließlich vorteilhafter Ausgestaltungen und Weiterbildungen der Erfindung aus dem Inhalt der Schutzansprüche, welche dieser Beschreibung nachgestellt sind.This object is achieved, including advantageous refinements and developments of the invention, from the content of the claims for protection which are set out in this description.
Die Erfindung sieht in ihrem Grundgedanken vor, daß Verriegelungszunge und Betätigung einstückig miteinander ausgebildet sind und die zwischen Gehäuse und Betätigung befindliche Innendichtung durch Anspritzen an das Gehäuse gebildet ist und daß die Betätigung und das die Betätigung umschließende Gehäuse unverlierbar miteinander verbunden sind, wobei die Innendichtung in wenigstens einem an der Betätigung ausgebildeten Freiraum zu liegen kommt. Mit der Erfindung ist der Vorteil verbunden, daß aufgrund der einstückigen Ausbildung von Betätigung und Verriegelungszunge neben dem so gebildeten Bauteil nur noch das Gehäuse herzustellen ist, wobei insbesondere die Innendichtung im sogenannten Zwei-K-Verfahren an das Gehäuse angespritzt und damit integraler Bestandteil des Vorreiberverschlusses wird. Durch die erfindungsgemäß vorgesehene unverlierbare Verbindung von Gehäuse und dem aus Betätigung und Verriegelungszunge bestehenden Bauteil ist in vorteilhafter Weise sichergestellt, daß die Verriegelungszunge nicht von der Betätigung gelöst werden kann, so daß im Zusammenwirken mit dem Gehäuse die Verschlußfunktion des Vorreiberverschlusses ständig gegeben ist.The basic idea of the invention is that the locking tongue and actuation are formed in one piece with one another and that the inner seal between the housing and the actuation is formed by injection molding onto the housing and that the actuation and the housing enclosing the actuation are captively connected to one another, the inner seal in at least one free space formed on the actuation comes to rest. The invention has the advantage that, due to the one-piece design of the actuation and locking tongue, in addition to the component thus formed, only the housing has to be produced, in particular the inner seal being molded onto the housing in the so-called two-component process and thus an integral part of the cam lock becomes. The captive connection provided according to the invention between the housing and the component consisting of actuation and locking tongue advantageously ensures that the locking tongue does not become detached from the actuation can be solved, so that in cooperation with the housing the locking function of the cam lock is always given.
Soweit nach einem Ausführungsbeispiel der Erfindung vorgesehen ist, daß die der Abdichtung des Gehäuses gegen die Betätigung dienende Innendichtung einstückig mit der der Abdichtung des Gehäuses gegen die Tür dienenden, an der Unterseite des Gehäusekopfes angeordneten Außendichtung ausgebildet ist und zur Verbindung von Außendichtung und Innendichtung an dem Gehäuse sich in dessen Längsrichtung erstreckende Kanäle zur Aufnahme von angespritzten Verbindungssträngen ausgebildet sind, ergibt sich daraus der besondere Vorteil, daß neben der Herstellung der Innendichtung auch die Außendichtung in den Vorreiberverschluß integriert ist, so daß eine hohe Schutzart beim Einsatz des erfindungsgemäß ausgestalteten Vorreiberverschlusses gewährleistet ist.Insofar as it is provided according to an embodiment of the invention that the sealing of the housing against actuation, the inner seal is formed in one piece with the sealing of the housing against the door, is arranged on the underside of the housing head and is used to connect the outer seal and the inner seal to the Housing extending in the longitudinal direction of channels for receiving molded connecting strands, this results in the particular advantage that in addition to the manufacture of the inner seal, the outer seal is integrated in the cam lock, so that a high degree of protection is guaranteed when using the cam lock designed according to the invention ,
Nach einem zweckmäßigen Ausführungsbeispiel der Erfindung ist vorgesehen, daß die unverlierbare Verbindung von Gehäuse und Betätigung bei gleichzeitiger Herstellung des Gehäuses durch Umspritzen der Betätigung hergestellt ist. Hierbei ergibt sich der besondere Vorteil der Einsparung eines weiteren Fertigungs- bzw. Montageschrittes.According to an expedient embodiment of the invention, it is provided that the captive connection of the housing and the actuation is produced by overmolding the actuation while the housing is being manufactured. This has the particular advantage of saving a further manufacturing or assembly step.
Nach einem Ausführungsbeispiel der Erfindung ist dabei vorgesehen, daß Betätigung und Gehäuse formschlüssig miteinander verbunden sind und die Betätigung in ihrem von dem Gehäuse umschlossenen Abschnitt eine radiale Einschnürung und das Gehäuse einen in die Einschnürung der Betätigung eingreifenden Absatz aufweisen und daß zur Ausbildung des Freiraumes die Längserstreckung der Einschnürung der Betätigung größer bemessen ist als die Längserstreckung des Absatzes des Gehäuses, wobei die Innendichtung zwischen Betätigung und Gehäuse in den jeweils durch den dem Gehäusekopf zugewandten Rand von Einschnürung und Absatz begrenzten Freiraum eingespritzt sein kann.According to an embodiment of the invention it is provided that the actuation and housing are positively connected to one another and the actuation in its section enclosed by the housing has a radial constriction and the housing has a shoulder engaging in the constriction of the actuation and that to form the free space, the longitudinal extent of the constriction of the actuation is larger than the longitudinal extent of the shoulder of the housing, wherein the inner seal between the actuator and the housing can be injected into the free space delimited by the edge of the constriction and heel facing the housing head.
Alternativ kann die unverlierbare Verbindung von Gehäuse und Betätigung aber auch durch Kleben, Nieten und Klipsen oder Verschweißen der beiden zu verbindenden Bauteile hergestellt sein.Alternatively, the captive connection of housing and actuation can also be produced by gluing, riveting and clipping or welding the two components to be connected.
Nach einem Ausführungsbeispiel der Erfindung ist vorgesehen, daß der zum Angriff eines Werkzeuges eingerichtete Kopf der Betätigung aus Zinkdruckguß besteht; durch diese Maßnahme wird die Widerstandsfähigkeit der Betätigung beim Zusammenwirken mit einem Öffnungswerkzeug erhöht, wobei der weitere Grundkörper der Betätigung gemeinsam mit der Verriegelungszunge einstückig ausgebildet und an den aus Zinkdruckguß bestehenden Kopf der Betätigung angespritzt ist.According to one embodiment of the invention, it is provided that the head of the actuation set up for attacking a tool consists of die-cast zinc; This measure increases the resilience of the actuation when interacting with an opening tool, the further main body of the actuation being formed in one piece together with the locking tongue and being injection molded onto the die-cast zinc head of the actuation.
Zur Ausbildung einer Schnellbefestigung ist nach einem Ausführungsbeispiel der Erfindung vorgesehen, daß das Gehäuse auf seiner an dem Gehäusekopf anschließenden Außenseite mit einem in zwei Gewindeabschnitte aufgeteilten Außengewinde versehen ist und die einander gegenüberliegend angeordneten Außengewindeabschnitte durch zwei jeweils plane Flächen voneinander getrennt sind und daß eine mit einer entsprechenden angepaßten Formgebung ausgebildete Überwurfmutter mit ihren planen Abschnitten bis zur Anlage an der Türrückseite auf das Gehäuse aufsteckbar und danach um einen Winkelbetrag drehbar ist, wobei die an den planen Flächen der Überwurfmutter ausgebildeten Innengewindeabschnitte mit den Außengewindeabschnitten des Gehäuses in Eingriff kommen.To form a quick attachment, it is provided according to an embodiment of the invention that the housing is provided on its outside adjoining the housing head with an external thread divided into two threaded sections and the mutually opposing external thread sections are separated from one another by two flat surfaces and that one with a Appropriate adapted shape trained union nut with its flat sections to the system The rear of the door can be plugged onto the housing and can then be rotated by an angular amount, the internal thread sections formed on the flat surfaces of the union nut coming into engagement with the external thread sections of the housing.
Soweit die unverlierbare Verbindung von Gehäuse und Betätigung durch Klipsen vorgesehen ist, ist nach einem Ausführungsbeispiel der Erfindung vorgesehen, daß an der dem Gehäusekopf gegenüberliegenden Stirnseite des Gehäuses zwei axial vorstehende Klipsarme mit in einer an der Betätigung ausgebildeten hinteren Nut eingreifenden Klipsvorsprüngen angeordnet sind, wobei die Klipsarme durch die aufgeschraubte Überwurfmutter in Eingriff mit der Betätigung gehalten sein können.Insofar as the captive connection of the housing and actuation by means of clips is provided, according to one embodiment of the invention it is provided that two axially projecting clip arms are arranged on the end face of the housing opposite the housing head with clip projections engaging in a rear groove formed on the actuation, the Clip arms can be held in engagement with the actuation by the screwed union nut.

Zustand.Status.
Wie sich zunächst aus Figur 1 ergibt, sind Betätigung 10 und Verriegelungszunge 11 als ein einstückiges Bauteil ausgebildet, wobei dieses Bauteil aus einem beliebigen Material hergestellt sein kann. Dabei kann es sich als zweckmäßig erweisen, wenn der Kopf 30 der Betätigung 10 aus Zinkdruckguß besteht, während der übrige Körper der Betätigung 10 einschließlich der Verriegelungszunge 11 aus Kunststoff besteht und an den Kopf 30 der Betätigung angespritzt ist. Die Betätigung 10 ist mit einer umlaufenden Einschnürung 12 versehen, die oberhalb der angeschlossenen Verriegelungszunge 1 1 eine geringere axiale Längserstreckung aufweist als auf dem übrigen Umfang der Betätigung 10.As can be seen initially from FIG. 1, actuation 10 and locking tongue 11 are formed as a one-piece component, this component being made from any material can. It may prove expedient if the head 30 of the actuator 10 consists of die-cast zinc, while the rest of the body of the actuator 10, including the locking tongue 11, is made of plastic and is molded onto the head 30 of the actuator. The actuator 10 is provided with a circumferential constriction 12, which has a smaller axial longitudinal extent above the connected locking tongue 11 than on the rest of the actuator 10.
Das in Figur 2 dargestellte Gehäuse 13 hat an seinem oberen Ende einen flanschartigen Gehäusekopf 14, mit welchem das Gehäuse 13 bei der Montage an einer Tür in Anlage an dem Türblatt kommt. Das Gehäuse 13 hat eine Innenbohrung 15 zur Aufnahme der Betätigung, und am unteren Ende des Gehäuses 13 weist das Gehäuse 13 einen umlaufenden Absatz 16 auf, der zum Zusammenwirken mit der Einschnürung 12 der Betätigung 10 (Figur 1) bestimmt ist und insoweit in Übereinstimmung mit der Gestalt der Einschnürung 12 jeweils eine entsprechende axiale Erstreckung aufweist.The housing 13 shown in Figure 2 has at its upper end a flange-like housing head 14, with which the housing 13 comes into contact with the door leaf when mounted on a door. The housing 13 has an inner bore 15 for receiving the actuation, and at the lower end of the housing 13 the housing 13 has a circumferential shoulder 16 which is intended to cooperate with the constriction 12 of the actuation 10 (FIG. 1) and in this respect in accordance with the shape of the constriction 12 in each case has a corresponding axial extent.
Dem in den Figuren 3 und 4 dargestellten Ausführungsbeispiel der unverlierbaren Verbindung des in Figur 1 dargestellten Bauteils mit dem in Figur 2 dargestellten Gehäuse 13 liegt ein Herstellungsverfahren zugrunde, bei welchem die Herstellung des die Betätigung 10 umschließenden Gehäuses 13 durch Umspritzen der Betätigung 10 mit einem geeigneten, spritzfähigen Material, vorzugsweise einem geeigneten Kunststoff, erfolgt. Bei diesem in Figur 3 dargestellten Spritzvorgang wird die axiale Längserstreckung des Absatzes 16 im Verhältnis zur Abmessung der Einschnürung 12 der Betätigung 10 derart bemessen, daß ein Freiraum 17 zwischen dem unteren Ende des Absatzes 16 und der benachbarten Begrenzungskante der Einschnürung 12 verbleibt. Wie aus Figur 4 ersichtlich ist, werden anschließend das Gehäuse 13 und die Betätigung 10 gegeneinander gedrückt, so daß sich das Gehäuse 13 gegenüber der Betätigung 10 axial verschiebt und der Freiraum 17 an das dem Gehäusekopf 14 zugewandte obere Ende der Einschnürung zu liegen kommt. In dieser Stellung wird der so verlagerte Freiraum mit einer Dichtungsmasse ausgespritzt, so daß sich in diesem Bereich die Innendichtung 18 ergibt. Da auf dem äußeren Umfang des Gehäuses 13 Kanäle 19 ausgebildet sind, die sich von der Innendichtung 18 bis an die Unterseite des Gehäusekopfes 14 erstrecken, fließt das in den Freiraum 17 eingespritzte Dichtungsmaterial über die Kanäle 19 in den Bereich des Gehäusekopfes 14 und bildet hier bei entsprechender Formgebung der zugeordneten Form gleichzeitig die Außendichtung 20 aus.The exemplary embodiment shown in FIGS. 3 and 4 of the captive connection of the component shown in FIG. 1 to the housing 13 shown in FIG. 2 is based on a manufacturing method in which the housing 13 surrounding the actuator 10 is manufactured by overmolding the actuator 10 with a suitable one , sprayable material, preferably a suitable plastic. In this injection molding process shown in FIG. 3, the axial longitudinal extent of the shoulder 16 is in relation to the dimension of the constriction 12 the actuation 10 dimensioned such that a free space 17 remains between the lower end of the shoulder 16 and the adjacent boundary edge of the constriction 12. As can be seen from Figure 4, the housing 13 and the actuator 10 are then pressed against each other, so that the housing 13 moves axially relative to the actuator 10 and the free space 17 comes to rest on the upper end of the constriction facing the housing head 14. In this position, the space displaced in this way is sprayed with a sealing compound, so that the inner seal 18 results in this area. Since channels 19 are formed on the outer circumference of the housing and extend from the inner seal 18 to the underside of the housing head 14, the sealing material injected into the free space 17 flows through the channels 19 into the area of the housing head 14 and forms here corresponding shape of the assigned shape, the outer seal 20 at the same time.
Aus Figur 5 ist die Konfiguration der insoweit in einem Bearbeitungsgang hergestellten Innendichtung 18 und Außendichtung 20 zu erkennen.The configuration of the inner seal 18 and outer seal 20 produced in one processing step can be seen from FIG.
Im Rahmen eines solchen Herstellungsvorganges kann es zweckmäßig sein, das Dichtungsmaterial mit einer anderen Farbgebung als Gehäuse und/oder Betätigung zu versehen, weil auf diese Weise durch Inaugenscheinnahme geprüft werden kann, daß insbesondere die Außendichtung 20 in ausreichender Form verwirktlicht ist. In den Figuren 6 und 7 ist ein anderes Ausführungsbeispiel des Vorreiberverschlusses dargestellt, welches eine Schnellbefestigung des Vorreiberverschlusses an einem nicht dargestellten Türblatt einschließt und weiterhin - im Unterschied zu dem zu Figuren 1 bis 5 beschriebenen Ausführungsbeispiel - von einer unverlierbaren Klipsverbindung zwischen Betätigung mit Verriegelungszunge und Gehäuse ausgeht.In the course of such a manufacturing process, it may be expedient to provide the sealing material with a different coloring than the housing and / or actuation, because it can be checked by visual inspection in this way that in particular the outer seal 20 has been effectively provided. FIGS. 6 and 7 show another exemplary embodiment of the sash lock, which includes a quick attachment of the sash lock to a door leaf, not shown, and further - in contrast to the exemplary embodiment described in FIGS. 1 to 5 - of a captive clip connection between actuation with the locking tongue and housing emanates.
Wie zunächst aus Figur 6 zu entnehmen ist, ist auf der Außenseite des Gehäuses 13 ein Außengewinde aufgebracht, welches in zwei einander gegenüberliegend angeordnete Außengewindeabschnitte 21 unterteilt ist, wobei diese Außengewindeabschnitte 21 durch zwei jeweils plane Flächen 22 voneinander getrennt sind. In einer entsprechenden Formgebung weist die auf das Gehäuse 13 aufschiebbare und zur Befestigung dienende Überwurfmutter 23 ein Innengewinde auf, welches ebenfalls zwei Innengewindeabschnitte 25 aufweist, die nunmehr an den an der Überwurfmutter 23 vorhandenen planen Flächen 24 ausgebildet sind; die planen Flächen 24 mit den daran ausgebildeten Innengewindeabschnitten 25 sind durch Kreisbogenabschnitte 26 miteinander verbunden. Die jeweils planen Flächen dienen zum axialen Aufschub der Überwurfmutter 23 bis zur Anlage an der rückwärtigen Fläche des (nicht dargestellten) Türbleches. Durch eine Teildrehung der Überwurfmutter 23 gegenüber dem Gehäuse 13 wird aufgrund einer entsprechend eingerichteten Gewindesteigung der Vorreiberverschluß an dem Gehäuse befestigt. Soweit zur unverlierbaren Verbindung von Gehäuse 13 und Betätigung 10 eine Klipsverbindung vorgesehen ist, sind an der dem Gehäusekopf 14 gegenüberliegenden Stirnseite des Gehäuses 13 zwei axial vorstehende Klipsarme 28 mit davon radial einwärts vorstehenden Klipsvorsprüngen 29 angeordnet, wobei die Klipsvorsprünge 29 in eine an der Betätigung 10 ausgebildete hintere, der Verriegelungszunge 1 1 benachbarte Nut 27 eingreifen. Zur besseren Montage können dabei die Klipsvorsprünge 29 mit einer entsprechenden Anschrägung ausgebildet sein. In montiertem Zustand (Figur 7) werden die Klipsarme 29 durch die aufgeschraubte Überwurfmutter 23 in Eingriff mit der Betätigung 10 gehalten.As can be seen initially from FIG. 6, an external thread is applied to the outside of the housing 13, which is divided into two external thread sections 21 arranged opposite one another, these external thread sections 21 being separated from one another by two flat surfaces 22 in each case. In a corresponding shape, the union nut 23, which can be pushed onto the housing 13 and is used for fastening, has an internal thread which likewise has two internal thread sections 25, which are now formed on the flat surfaces 24 present on the union nut 23; the flat surfaces 24 with the internal thread sections 25 formed thereon are connected to one another by circular arc sections 26. The respective flat surfaces serve to axially slide the union nut 23 until it rests against the rear surface of the door plate (not shown). By a partial rotation of the union nut 23 relative to the housing 13, the cam lock is fastened to the housing due to a correspondingly configured thread pitch. Insofar as a clip connection is provided for the captive connection of housing 13 and actuation 10, two axially projecting clip arms 28 with radially inward projecting clip projections 29 are arranged on the front side of the housing 13 opposite the housing head 14, the clip projections 29 in one on the actuation 10 trained rear, the locking tongue 1 1 adjacent groove 27 engage. For better assembly, the clip projections 29 can be designed with a corresponding bevel. In the assembled state (FIG. 7), the clip arms 29 are held in engagement with the actuation 10 by the screwed-on union nut 23.
Auf der Außenseite der Überwurfmutter 23 ist bei dem dargestellten Ausführungsbeispiel eine Außenverzahnung 31 vorgesehen, an der ein geeignetes Werkzeug zum Montieren der Überwurfmutter 23In the illustrated embodiment, an external toothing 31 is provided on the outside of the union nut 23, on which a suitable tool for mounting the union nut 23
#angesetzt werden kann.# can be applied.
