The installed cover is unable to rotate relative to the equipment. If the equipment is mounted on a base surface, the cover may also be supported against this. The springs may support the cover under tension, and if the equipment is cylindrical, they may each have a tongue which engages with the cylindrical surface at separate points around its circumference.

Description

Die Erfindung betrifft einen Haubenhalter an Abdeckhauben für Türschließergehäuse, welcher in Einbaulage an der Abdeckhaube sowie an dem Türschließergehäuse gehalten ist und wenigstens eine Haltefeder zum Abstützen der Abdeckhaube an dem Türschließergehäuse aufweist.The invention relates to a hood holder on covers for door closer housing, which is held in the installed position on the cover and on the door closer housing and has at least one retaining spring for supporting the cover on the door closer housing.

Derartige Haubenhalter werden zum insbesondere lösbaren Befestigen von Abdeckhauben an Türschließergehäusen verwendet, wobei die Abdeckhauben ihrerseits das Türschließergehäuse und das darin enthaltene Türschließergetriebe gegen Umwelteinflüsse bzw. Verschmutzung schützen und der Türschließer-Anlage ein ansprechendes Aussehen geben.Such hood holders are used for releasably attaching covers to door closer housings, the covers in turn protecting the door closer housing and the door closer transmission contained therein against environmental influences or contamination and giving the door closer system an attractive appearance.

Bekanntermaßen werden gattungsgemäße Haubenhalter mit einem ringartigen Grundkörper und daran diametral verlaufenden und in axialer Richtung elastischen Kunststoff-Blattfedern verwendet. Im Querschnittsmittelpunkt des ringförmigen Grundkörpers ist im Kreuzungsbereich der diametralen Blattfedern ein in axialer Richtung vorstehender Lagerzapfen angebracht. Zur Montage der Abdeckhaube wird der bekannte Haubenhalter mit dem ringförmigen Grundkörper auf einen Vorsprung an der Stirnfläche des betreffenden Türschließergehäuses aufgesteckt. Von der gegenüberliegenden Stirnfläche des Türschließergehäuses steht ebenfalls ein Lagerzapfen axial vor. Die Abdeckhaube ist an ihren den Stirnflächen des Türschließergehäuses zugeordneten Flächen mit Aufnahmeöffnungen für die beiden beschriebenen Lagerzapfen versehen. Nach dem Aufstecken des vorbekannten Haubenhalters auf das Türschließergehäuse wird die Abdeckhaube an der gegenüberliegenden Gehäuse-Stirnfläche unter einem Winkel gegen die Montageebene des Türschließergehäuses geneigt angesetzt und anschließend so weit in Längsrichtung des Türschließergehäuses verschoben, bis der von dieser Stirnfläche vorstehende Lagerzapfen in die Aufnahmebohrung der zugeordneten Abdeckhaubenfläche eingreift. Anschließend wird das freie Ende der Abdeckhaube gegen die Montageebene des Türschließergehäuses geschwenkt und gleichzeitig der Lagerzapfen des Haubenhalters mittels eines Montagehilfsmittels, beispielsweise eines Schraubendrehers, gegen die Wirkung der Blattfedern in Richtung auf die Stirnfläche des Türschließergehäuses gedrückt. Da infolgedessen der Lagerzapfen des Haubenhalters gegenüber der Schwenkbahn der Stirnfläche der Abdeckhaube zurückversetzt ist, kann die Abdeckhaube gegen die Montageebene des Türschließergehäuses bis in ihre Endstellung verschwenkt werden. In der Schwenk-Endstellung der Abdeckhaube rastet der Lagerzapfen des Haubenhalters in die hierfür vorgesehene Aufnahmeöffnung an der zugeordneten Stirnfläche der Abdeckhaube ein. In der Einbaulage wird die Abdeckhaube durch die beiden von dem Türschließergehäuse axial vorstehenden Lagerzapfen gehalten.As is known, generic hood holders with a ring-like base body and diametrically extending and axially elastic plastic leaf springs are used. At the cross-sectional center of the ring-shaped base body, a bearing journal projecting in the axial direction is attached in the area of intersection of the diametrical leaf springs. To mount the cover, the known hood holder with the ring-shaped base body is pushed onto a projection on the end face of the door closer housing in question. A bearing journal also projects axially from the opposite end face of the door closer housing. The cover is provided on its faces assigned to the end faces of the door closer housing with receiving openings for the two bearing journals described. After the known hood holder has been plugged onto the door closer housing, the cover hood is placed on the opposite front face of the housing at an angle to the mounting plane of the door closer housing and then moved so far in the longitudinal direction of the door closer housing until the bearing pin protruding from this end face into the mounting hole of the assigned one Cover surface engages. The free end of the cover hood is then pivoted against the mounting plane of the door closer housing and at the same time the bearing journal of the hood holder is pressed against the action of the leaf springs in the direction of the end face of the door closer housing by means of an assembly aid, for example a screwdriver. As a result, since the bearing pin of the hood holder is set back with respect to the swivel path of the end face of the cover hood, the cover hood can be against the mounting plane of the door closer housing be pivoted into their end position. In the swivel end position of the cover, the bearing pin of the cover holder engages in the receiving opening provided for this purpose on the associated end face of the cover. In the installed position, the cover is held by the two bearing pins projecting axially from the door closer housing.

Die Ausbildung des bekannten Haubenhalters bedingt zum einen den vorstehend beschriebenen Montageablauf und zum anderen eine lediglich punktuelle Lagerung der montierten Abdeckhaube an deren Stirnflächen. Im Falle von Fertigungstoleranzen kann sich die Abdeckhaube um die eine Drehachse bildenden Lagerzapfen des Haubenhalters bzw. der gegenüberliegenden Stirnfläche des Türschließergehäuses relativ zu diesem drehen. Aufgrund des in diesen Fällen bestehenden Spiels kann es insbesondere bei Erschütterungen der Türschließer-Anlage, wie sie beispielsweise auftreten, wenn die betreffende Tür ins Schloß fällt, zu unerwünschten Klappergeräuschen kommen.The design of the known hood holder requires, on the one hand, the assembly process described above and, on the other hand, only a selective mounting of the mounted cover hood on its end faces. In the case of manufacturing tolerances, the cover hood can rotate relative to the door closer housing about the bearing journal of the hood holder or the opposite end face of the door closer housing which forms an axis of rotation. Because of the play in these cases, undesirable rattling noises can occur, in particular when the door closer system is shaken, as occurs, for example, when the door in question locks.

Nach alledem besteht im Falle der bekannten Haubenhalter ein Verbesserungspotential sowohl hinsichtlich der durch den Haubenhalter bedingten Montagefreundlichkeit der Abdeckhaube als auch hinsichtlich deren mit dem Haubenhalter erzielten Lagefixierung.After all, in the case of the known hood holder, there is potential for improvement both with regard to the ease of installation of the cover hood due to the hood holder and with regard to the positional fixation achieved with the hood holder.

In einer entsprechenden Weiterbildung der bekannten Haubenhalter besteht die Aufgabe der Erfindung.The object of the invention is a corresponding development of the known hood holder.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an einem Haubenhalter der eingangs genannten Art die Abdeckhaube an dem Türschließergehäuse drehfest gelagert und die Haltefeder(n) in Einbaulage an dem Türschließergehäuse lösbar verrastet ist (sind). Durch die drehfeste Lagerung der Abdeckhaube an dem Türschließergehäuse werden unerwünschte Relativ-Drehbewegungen der beiden Bauteile ebenso vermieden wie damit gegebenenfalls verbundene Klappergeräusche. Da das Türschließergehäuse selbst fest angebracht ist, ist durch die drehfeste Lagerung der Abdeckhaube an dem Türschließergehäuse eine spiel freie Lagerung der Abdeckhaube gegenüber dessen Umgebung gewährleistet. Die Verrastbarkeit der Haltefeder an dem Türschließergehäuse erlaubt eine einfache Montage und bei entsprechender Ausgestaltung der Rastverbindung eine ebenso einfache Demontage der Abdeckhaube. So läßt sich die Abdeckhaube einhändig auf das Türschließergehäuse aufschieben und selbsttätig in ihrer Einbaulage fixieren.This object is achieved in that on a hood holder of the type mentioned, the cover on the door closer housing is rotatably mounted and the retaining spring (s) is (are) releasably locked in the installed position on the door closer housing. Due to the rotationally fixed mounting of the cover on the door closer housing, undesired relative rotational movements of the two components as well as any rattling noises associated therewith are avoided. Since the door closer housing itself is firmly attached, play-free storage of the cover relative to its surroundings is ensured by the non-rotatable mounting of the cover on the door closer housing. The latching ability of the retaining spring on the door closer housing permits simple assembly and, with a corresponding design of the latching connection, also simple disassembly of the cover hood. The cover can thus be pushed onto the door closer housing with one hand and automatically fixed in its installed position.

Im Falle von erfindungsgemäßen Haubenhaltern an Abdeckhauben für auf einer Grundfläche angeordnete Türschließergehäuse ist in Weiterbildung der Erfindung vorgesehen, daß die Haltefeder(n) die Abdeckhaube gegen die Grundfläche des Türschließergehäuses abstützt (abstützen) . Derartige Haubenhalter sorgen dafür, daß die Abdeckhaube an ihrer öffnungsseitig umlaufenden Kante an der Grundfläche des Türschließergehäuses anliegt. Die drehfeste Lagerung der Abdeckhaube an dem Türschließergehäuse wird demnach durch die Haltefeder(n) selbst bewirkt. Damit zweckmäßigerweise verbunden ist eine stabile und gegen unerwünschtes Schlackern gesicherte Abstützung der Abdeckhaube.In the case of hood holders according to the invention on cover hoods for door closer housings arranged on a base surface, in a further development of the invention it is provided that the retaining spring (s) supports the cover hood against the base surface of the door closer housing. Such hood holders ensure that the cover abuts the base surface of the door closer housing at its edge encircling the opening. The rotatable mounting of the cover on the door closer housing is therefore effected by the retaining spring (s) themselves. This is expediently associated with a stable support of the covering hood which is secured against undesired slagging.

Eine bevorzugte Ausführungsform des erfindungsgemäßen Haubenhalters zeichnet sich dadurch aus, daß die Haltefeder(n) die Abdeckhaube unter Vorspannung abstützt (abstützen). Aufgrund ihrer Vorspannung ist die Haltefeder bzw. sind die Haltefedern eines derartigen Haubenhalters in der Lage, Fertigungstoleranzen an den aneinander abzustützenden Bauteilen auszugleichen.A preferred embodiment of the hood holder according to the invention is characterized in that the retaining spring (s) supports the cover hood under pretension. Because of their pretension, the retaining spring or the retaining springs of such a hood holder are able to compensate for manufacturing tolerances on the components to be supported against one another.

Ein erfindungsgemäßer Haubenhalter an Abdeckhauben für zylindrische Türschließergehäuse weist vorteilhafterweise als Haltefedern wenigstens zwei federnde Rastzungen auf, welche sich in Einbaulage an der Mantelfläche des Türschließergehäuses mit Abstand voneinander in Umfangsrichtung der Mantelfläche abstützen. Die Verwendung zweier Haltefedern bedingt eine stabilisierende und einem Schlackerspiel entgegenwirkende Zweipunktabstützung der Abdeckhaube an dem Türschließergehäuse. Kommt die Abdeckhaube darüber hinaus noch an weiteren Punkten, beispielsweise des Türschließergehäuses und/oder einer etwa vorhandenen Grundfläche des Türschließergehäuses, zur Anlage, so ist eine spiel freie Lagerung der Abdeckhaube gewährleistet. Darüber hinaus unterstützen die federnden Rastzungen bei entsprechender Ausbildung die Montage der Abdeckhaube. So ist es konstruktiv möglich, die Rastzungen derart auszurichten, daß sie ab einem gewissen Stadium der Bewegung, mit der die Abdeckhaube auf das Türschließergehäuse aufgeschoben wird, die Abdeckhaube in Aufschubrichtung kraftbeaufschlagen.A hood holder according to the invention on cover hoods for cylindrical door closer housings advantageously has at least two resilient locking tongues as retaining springs, which are supported in the installed position on the outer surface of the door closer housing at a distance from one another in the circumferential direction of the outer surface. The use of two retaining springs requires a stabilizing two-point support of the cover hood on the door closer housing which counteracts a slag play. If the cover also comes into contact at other points, for example the door closer housing and / or an existing base area of the door closer housing, play-free storage of the cover is guaranteed. In addition, the resilient latching tongues support the assembly of the cover hood with appropriate training. Thus, it is structurally possible to align the locking tongues in such a way that, after a certain stage of the movement with which the cover is pushed onto the door closer housing, they force the cover in the push-on direction.

Dem Einrasten der Haltefedern an dem jeweils zugehörigen Türschließergehäuse geht eine Gleitbewegung des dem Türschließergehäuse zugewandten Endes der jeweiligen Haltefeder entlang der Gehäuseoberfläche voraus. Ein entsprechender schleifender Kontakt zwischen Haltefedern und Türschließergehäuse ergibt sich bei der Demontage von Abdeckhauben. Damit sich nun die bei den beschriebenen Gleitbewegungen an der Berührungsfläche von Haltefeder und Türschließergehäuse auftretende Reibung auf ein Minimum reduziert, ist in weiterer Ausgestaltung der Erfindung vorgesehen, daß die Haltefeder(n) an dem das Türschließergehäuse beaufschlagenden Ende abgerundet, vorzugsweise mit zylindrischem Querschnitt, ausgebildet ist (sind). An sphärisch gekrümmten Federenden ergibt sich eine Punktberührung, an zylindrischen Federenden eine linienförmige Berührung mit der Gegenfläche des Türschließergehäuses.The latching of the retaining springs on the respectively associated door closer housing is preceded by a sliding movement of the end of the respective retaining spring facing the door closer housing along the housing surface. A corresponding sliding contact between the retaining springs and the door closer housing results when the cover hoods are removed. So that the friction occurring in the described sliding movements on the contact surface of the retaining spring and the door closer housing is reduced to a minimum, it is provided in a further embodiment of the invention that the retaining spring (s) is rounded at the end acting on the door closer housing, preferably with a cylindrical cross section is (are). There is a point contact on spherically curved spring ends, and a linear contact on the cylindrical spring ends with the counter surface of the door closer housing.

Erfindungsgemäß kann eine spielfreie Lagerung der Abdeckhaube an dem Türschließergehäuse dadurch erreicht werden, daß zwischen dem Haubenhalter und dem Türschließergehäuse und gleichzeitig zwischen dem Haubenhalter und der Abdeckhaube eine gegen unerwünschte Relativbewegungen gesicherte Abstützung vorgesehen ist.According to the invention, a play-free mounting of the cover on the door closer housing can be achieved in that a support secured against undesired relative movements is provided between the hood holder and the door closer housing and at the same time between the hood holder and the cover.

Der Festlegung des Haubenhalters an dem Türschließergehäuse dient es, daß - wie in weiterer Ausgestaltung der Erfindung vorgesehen - der Haubenhalter in Einbaulage an einer Anlagefläche formschlüssig an einer Gegenfläche des Türschließergehäuses abgestützt ist. Im Sinne einer spiel freien Lagerung des Haubenhalters an der Abdeckhaube ist erfindungsgemäß vorgesehen, daß der Haubenhalter an der Abdeckhaube flächig und/oder über federnde Positionierarme abgestützt ist. Zudem erleichtern die Abstützflächen der erfindungsgemäßen Haubenhalter ebenso wie deren federnde Positionierarme die Montage der Abdeckhaube, indem sie beispielsweise bei der Vormontage des Haubenhalters für eine Zwangsführung von Haubenhalter und Abdeckhaube in ihre Sollstellung relativ zueinander sorgen.The fixing of the hood holder on the door closer housing serves that - as provided in a further embodiment of the invention - the hood holder is positively supported in the installed position on a contact surface on a counter surface of the door closer housing. In the sense of a play-free storage of the hood holder on the cover it is provided according to the invention that the hood holder is supported flat on the cover and / or via resilient positioning arms. In addition, the support surfaces of the hood holder according to the invention, as well as their resilient positioning arms, facilitate the assembly of the cover hood, for example by forcing the hood holder and cover hood into their desired position relative to one another during the pre-assembly of the hood holder.

Die Montagearbeiten werden des weiteren dadurch erleichtert, daß der Haubenhalter klemmend an der Abdeckhaube gehalten ist. Die Klemmverbindung von Haubenhalter und Abdeckhaube erlaubt es außerdem, die Abdeckhaube jederzeit ohne Einsatz von Montagehilfsmitteln zu demontieren.The assembly work is further facilitated in that the hood holder is held clamped to the cover. The clamp connection of the hood holder and cover hood also allows the cover hood to be removed at any time without the use of assembly aids.

In Einzelfällen kann es jedoch zweckmäßig sein, die Demontage der Abdeckhaube zu erschweren, ohne jedoch die Handhabungsfreundlichkeit bei der Montage zu beeinträchtigen. So sollen sich etwa Abdeckhauben auch an Türschließer-Anlagen in öffentlichen Gebäuden möglichst einfach anbringen lassen. Gleichzeitig soll das Abnehmen der Abdeckhauben aber, beispielsweise zum Schutz gegen Vandalismus, nur unter erschwerten Bedingungen möglich sein. Insbesondere für derartige Einsatzfälle ist eine Ausführungsform des erfindungsgemäßen Haubenhalters bestimmt, bei der der Haubenhalter einen in Längsrichtung des Türschließergehäuses über dieses vorstehenden und in dieser Richtung federnden Rastvorsprung aufweist und an diesem über eine an der zugeordneten Stirnfläche der Abdeckhaube vorgesehene Rastaufnahme mit der Abdeckhaube lösbar verrastet ist und welche sich dadurch auszeichnet, daß der Haubenhalter die mit ihm verrastete Abdeckhaube über die Haltefeder(n), gegen Abziehen von dem Türschließergehäuse gesperrt, an letzterem abstützt. Unter Verwendung eines derartigen Haubenhalters läßt sich die Abdeckhaube, wie bereits vorstehend beschrieben, auf einfachste Art und Weise, beispielsweise durch einhändiges Aufschieben auf das Türschließergehäuse, anbringen. Ein entsprechendes Abziehen der aus dem Haubenhalter und der Abdeckhaube bestehenden Baueinheit von dem Türschließergehäuse wird jedoch durch die Haltefeder(n) verhindert. Statt dessen bedarf es zum Abnehmen der Abdeckhaube eines Montagehilfsmittels, etwa eines Schraubendrehers, mit dem sich der in die Stirnfläche der Abdeckhaube eingreifende Rastvorsprung des Haubenhalters in das Innere der Abdeckhaube eindrücken und dadurch die zwischen dem Haubenhalter und der Abdeckhaube bestehende Verriegelung lösen läßt. Erst danach kann die Abdeckhaube von dem nach wie vor in Einbaulage gehaltenen Haubenhalter getrennt werden.In individual cases, however, it may be expedient to make it more difficult to dismantle the cover hood, without, however, impairing the ease of use during assembly. For example, cover hoods should also be as easy as possible to attach to door closer systems in public buildings. At the same time, it should only be possible to remove the covers, for example to protect against vandalism, under difficult conditions. In particular for such applications, an embodiment of the hood holder according to the invention is intended, in which the hood holder has a locking projection projecting in the longitudinal direction of the door closer housing and projecting in this direction and is detachably locked to the cover hood by a locking receptacle provided on the associated end face of the cover hood and which is characterized in that the hood holder supports the cover, which is locked with it, via the retaining spring (s), locked against being pulled off the door closer housing, on the latter. Using such a hood holder, the cover hood can be attached in the simplest way, as already described above, for example by pushing it onto the door closer housing with one hand. A corresponding removal of the structural unit consisting of the hood holder and the cover hood from the door closer housing is prevented by the retaining spring (s). Instead, it is necessary to remove the cover of an assembly aid, such as a screwdriver, with which the latching projection of the hood holder which engages in the end face of the cover can be pressed into the interior of the cover and thereby release the locking existing between the cover holder and the cover. Only then can the cover hood be separated from the hood holder that is still in the installed position.

Eine zweckmäßige und konstruktiv einfach gestaltete Ausführungsform der Erfindung, mit der sich vorstehend beschriebene Funktionen realisieren lassen, ist dadurch gekennzeichnet, daß der Haubenhalter im Querschnitt im wesentlichen U-förmig ausgebildet ist, wobei die Stegfläche des Haubenhalters einer Stirnfläche der Abdeckhaube sowie der entsprechenden Stirnfläche des Türschließergehäuses zugeordnet ist, eine an der der Abdeckhaube zugewandten Seite mit dem Rastvorsprung versehene federnde Riegelzunge und an der dem Türschließergehäuse zugewandten Seite eine U-förmig geöffnete und die Anlagefläche zur Formschlußverbindung mit dem Türschließergehäuse bildende Anschlagrippe aufweist und wobei die Schenkelflächen des Haubenhalters in Längsrichtung des Türschließergehäuses mit diesem überlappen, an der dem Türschließergehäuse zugewandten Seite jeweils eine der federnden Rastzungen, an der der Abdeckhaube zugewandten Seite unter Bildung der flächigen Abstützung der Abdeckhaube jeweils eine Klemmfeder zur Herstellung der Klemmverbindung mit der Abdeckhaube und jeweils einen gegen die Abdeckhaube vorstehenden federnden Positionierarm aufweisen.An expedient and structurally simple embodiment of the invention, with which the functions described above can be realized, is characterized in that the hood holder is essentially U-shaped in cross section, the web surface of the hood holder being an end face of the cover hood and the corresponding end face of the Door closer housing is assigned, a resilient locking tongue provided on the side facing the cover with the locking projection and on the side facing the door closer housing has a U-shaped opening and forms the abutment rib for form-fitting connection with the door closer housing, and wherein the leg surfaces of the hood holder in the longitudinal direction of the door closer housing overlap with this, on the side facing the door closer housing one of the resilient latching tongues, on the side facing the cover hood, each with a clamping spring for producing the clamping connection with the cover hood and one each have a resilient positioning arm protruding from the cover.

Ist der Haubenhalter - wie dies erfindungsgemäß außerdem vorgesehen ist - bezüglich einer längs des Türschließergehäuses senkrecht zu dessen Montageebene verlaufenden Mittelebene symmetrisch ausgebildet, so läßt er sich wahlweise an jeder der beiden Stirnflächen des Türschließergehäuses verwenden.If the hood holder - as is also provided according to the invention - is symmetrical with respect to a central plane running along the door closer housing perpendicular to its mounting plane, it can be used optionally on each of the two end faces of the door closer housing.

Insbesondere aus Kostengründen ist es zweckmäßig, daß erfindungsgemäße Haubenhalter als Kunststoff-Spritzgußteile ausgebildet sind.Particularly for reasons of cost, it is expedient that hood holders according to the invention are designed as plastic injection molded parts.

In den Fign. 1a bis 1d dargestellt ist ein im Querschnitt im wesentlichen U-förmiger Haubenhalter 1 mit einer Stegfläche 2 sowie dazu senkrecht verlaufenden Schenkelflächen 3, 4. In der Stegfläche 2 des als Spritzgußteil gefertigten Haubenhalters 1 sind eine schlüssellochartige Öffnung 5 sowie dieser benachbarte fensterartige Aussparungen 6, 7 vorgesehen. In das Innere der schlüssellochartigen Öffnung 5 ragt eine senkrecht zu der Zeichenebene der Fig. 1a federnde Riegelzunge 8 mit einem mittigen Rastvorsprung in Form eines Rastzapfens 9. Zur Gewährleistung der elastischen Beweglichkeit ist die Riegelzunge 8 mit einer Dünnstelle 10 an den benachbarten Bereich der Stegfläche 2 angespritzt. An ihrer insbesondere in Fig. 1d gezeigten Rückseite weist die Stegfläche 2 eine U-förmige Anschlagrippe 11 mit einer senkrecht von der Stegfläche 2 vorstehenden Anlagefläche 12 auf.In Figs. 1a to 1d, a cross-sectionally substantially U-shaped hood holder 1 is shown with a web surface 2 and leg surfaces 3, 4 running perpendicularly thereto. In the web surface 2 of the hood holder 1 manufactured as an injection molded part, there is a keyhole-like opening 5 and adjacent window-like recesses 6, 7 provided. In the interior of the keyhole-like opening 5, a locking tongue 8 protrudes perpendicular to the plane of the drawing in FIG. 1a with a central locking projection in the form of a locking pin 9. To ensure the elastic mobility, the locking tongue 8 with a thin point 10 is at the adjacent area of the web surface 2 molded. On its rear side, which is shown in particular in FIG. 1d, the web surface 2 has a U-shaped stop rib 11 with a contact surface 12 projecting perpendicularly from the web surface 2.

Die Schenkelflächen 3, 4 sind mit Haltefedern in Form von gegeneinander gerichteten elastischen Rastzungen 13, 14 und federnden Positionierarmen 15, 16 versehen. In fensterartige Aussparungen der Schenkelflächen 3, 4 ragen Klemmfedern 17, 18, die in Ausgangslage über die Schenkelflächen 3, 4 ebenso vorstehen wie die Riegelzunge 8 mit dem Rastzapfen 9 über die Stegfläche 2. Die freien Enden der Rastzungen 13, 14 sowie der Positionierarme 15, 16 sind mit einem zylindrischen Querschnitt ausgebildet. Die wahlweise Rechts-/Linksverwendbarkeit des Haubenhalters 1 resultiert aus seiner symmetrischen Ausbildung bezüglich der in der Schnittlinie I-I der Fig. 1a senkrecht zu der Zeichenebene verlaufenden Mittelebene.The leg surfaces 3, 4 are provided with retaining springs in the form of mutually directed elastic locking tongues 13, 14 and resilient positioning arms 15, 16. In window-like recesses of the leg surfaces 3, 4 protrude clamping springs 17, 18, which in the starting position project over the leg surfaces 3, 4 as well as the locking tongue 8 with the locking pin 9 over the web surface 2. The free ends of the locking tongues 13, 14 and the positioning arms 15 , 16 are formed with a cylindrical cross section. The optional right / left usability of the hood holder 1 results from its symmetrical design with respect to the central plane running perpendicular to the plane of the drawing in the section line I-I of FIG. 1a.

Wie aus den Fign. 2a und 2b hervorgeht, wird bei der Montage einer Abdeckhaube 19 an dieser zunächst der Haubenhalter 1 vormontiert. An Stirnflächen 20, 21 ist die Abdeckhaube 19 mit Rastaufnahmen 22, 23 versehen. In einer Längsfläche 24 ist ein randoffener Ausschnitt 25 ausgespart.As shown in Figs. 2a and 2b, the hood holder 1 is first preassembled when a cover hood 19 is mounted thereon. The cover hood 19 is provided with snap-in receptacles 22, 23 on end faces 20, 21. A cutout 25 open at the edge is left out in a longitudinal surface 24.

Zur Vormontage wird nun der Haubenhalter 1 mit den Positionierarmen 15, 16 zuvorderst in das Innere der Abdeckhaube 19 eingesetzt. Dabei wird der Haubenhalter 1 derart ausgerichtet, daß der Rastzapfen 9 in die Rastaufnahme 22 an der Stirnfläche 20 der Abdeckhaube 19 eingreift. Die Schenkelflächen 3, 4 des Haubenhalters 1 sorgen für dessen flächige Abstützung im Innern der Abdeckhaube 19. Eine klemmende Verbindung zwischen beiden Bauteilen wird hergestellt mit Hilfe der Klemmfedern 17, 18, die im Zusammenwirken mit der Formschlußverbindung zwischen dem Rastzapfen 9 und der Rastaufnahme 22 den Haubenhalter 1 an der Abdeckhaube 19 in Vormontagelage fixieren.For pre-assembly, the hood holder 1 with the positioning arms 15, 16 is first inserted into the interior of the cover hood 19. The hood holder 1 is aligned such that the locking pin 9 engages in the locking receptacle 22 on the end face 20 of the cover 19. The leg surfaces 3, 4 of the hood holder 1 ensure its flat support inside the cover hood 19. A clamping connection between the two components is established with the aid of the clamping springs 17, 18, which in cooperation with the positive connection between the locking pin 9 and the snap-in receptacle 22 fix the hood holder 1 to the cover hood 19 in the preassembly position.

Gemäß Fig. 3 wird im Laufe der Endmontage zunächst die aus der Abdeckhaube 19 sowie dem Haubenhalter 1 bestehende Baueinheit mit ihrem dem Haubenhalter 1 abgewandten Ende an die Montagefläche eines Türschließergehäuses 26 angesetzt. Dabei ist das mit dem vormontierten Haubenhalter 1 versehene Ende der Abdeckhaube 19 unter einem spitzen Winkel gegen die Montageebene des Türschließergehäuses 26 verschwenkt ausgerichtet. Ausgehend von der in Fig. 3 gezeigten Stellung wird die Abdeckhaube 19 durch Verschieben in Längsrichtung über die Rastaufnahme 23 an ihrer Stirnfläche 21 mit einem in Fig. 3 nicht erkennbaren Lagerzapfen an der zugeordneten Stirnfläche des Türschließergehäuses 26 zum Eingriff gebracht. Anschließend wird das freie Ende der Abdeckhaube 19 mit dem daran vormontierten Haubenhalter 1 in Richtung des Pfeiles 27 in Fig. 3 gegen die Montagefläche des Türschließergehäuses 26 geschwenkt. Bei dieser Schwenkbewegung laufen die Rastzungen 13, 14 zunächst auf die Mantelfläche des zylindrischen Türschließergehäuses 26 auf. Bei fortgesetzter Schwenkbewegung gleiten sie mit ihren im Querschnitt zylindrischen Enden an der Mantelfläche des Türschließergehäuses 26 entlang. Da zwischen den im Querschnitt zylindrischen Enden der Rastzungen 13, 14 und der Mantelfläche des Türschließergehäuses 26 eine lediglich linienförmige Berührung stattfindet, wird dieser Gleitbewegung ein relativ geringer Reibungswiderstand entgegengesetzt. Mit der Gleitbewegung verbunden ist eine gegen Federkraft ausgeführte Schwenkbewegung der Rastzungen 13, 14 in Richtung auf die jeweils zugeordnete Schenkelfläche 3, 4 des Haubenhalters 1. Sobald nun die freien Enden der Rastzungen 13, 14 jeweils den "höchsten" Punkt des zylindrischen Türschließergehäuses 26 passiert haben, schwenken sie aufgrund der wirksamen Federkraft selbsttätig in ihre beispielsweise in Fig. 1a gezeigte Ausgangslage zurück. Dabei stützen sich die Rastzungen 13, 14 an dem zu der Montagefläche weisenden Teil der Mantelfläche des Türschließergehäuses 26 ab. Das Abdeckgehäuse 19 erfährt infolge des Rückfederns der Rastzungen 13, 14 eine Kraftbeaufschlagung in Richtung auf die Montagefläche des Türschließergehäuses 26, wodurch das Aufschieben der Abdeckhaube 19 unterstützt wird. Diese kommt schließlich über die Rastzungen 13, 14 beaufschlagt mit ihrem Öffnungsrand an der Montagefläche des Türschließergehäuses 26 zur Anlage. Die beschriebenen montageunterstützenden Effekte ergeben sich im übrigen an allen Bauformen von Türschließergehäusen mit sich in Montagerichtung verjüngender Gehäusekontur.According to FIG. 3, in the course of the final assembly, the assembly consisting of the cover hood 19 and the hood holder 1 is first attached to the mounting surface of a door closer housing 26 with its end facing away from the hood holder 1. The end of the cover 19 provided with the preassembled hood holder 1 is pivoted at an acute angle against the mounting plane of the door closer housing 26. Starting from the position shown in FIG. 3, the covering hood 19 is brought into engagement by sliding in the longitudinal direction via the latching receptacle 23 on its end face 21 with a bearing journal (not recognizable in FIG. 3) on the associated end face of the door closer housing 26. Subsequently, the free end of the cover hood 19 with the hood holder 1 pre-mounted thereon is pivoted in the direction of arrow 27 in FIG. 3 against the mounting surface of the door closer housing 26. During this pivoting movement, the latching tongues 13, 14 initially run onto the lateral surface of the cylindrical door closer housing 26. With continued pivoting movement they slide with their ends which are cylindrical in cross section along the outer surface of the door closer housing 26. Since there is only a linear contact between the ends of the latching tongues 13, 14, which are cylindrical in cross section, and the lateral surface of the door closer housing 26, this sliding movement is opposed to a relatively low frictional resistance. Connected to the sliding movement is a pivoting movement of the latching tongues 13, 14 in the direction of the respectively assigned leg surface against spring force 3, 4 of the hood holder 1. As soon as the free ends of the locking tongues 13, 14 each have passed the "highest" point of the cylindrical door closer housing 26, they automatically pivot back into their starting position, for example shown in FIG. 1a, due to the effective spring force. The latching tongues 13, 14 are supported on the part of the outer surface of the door closer housing 26 which faces the mounting surface. As a result of the springbacks of the latching tongues 13, 14, the cover housing 19 is subjected to a force in the direction of the mounting surface of the door closer housing 26, which supports the pushing on of the cover hood 19. This finally comes to rest on the latching tongues 13, 14 with their opening edge on the mounting surface of the door closer housing 26. The described assembly-supporting effects also result from all designs of door closer housings with a housing contour that tapers in the mounting direction.

In der Endmontagestellung, in der die Abdeckhaube (19) spielfrei abgestützt gehalten ist, umschließt der randoffene Ausschnitt 25 die in Fig. 3 andeutungsweise erkennbare und aus der Abdeckhaube 19 nach oben austretende Welle der gezeigten Türschließer-Anlage. Die U-förmige Anschlagrippe 11 umgreift einen an der in Fig. 3 sichtbaren Stirnfläche des Türschließerghäuses 26 vorgesehenen Vorsprung und schafft dadurch eine formschlüssige Verbindung zwischen dem Haubenhalter 1 und dem Türschließergehäuse 26.In the final assembly position, in which the cover (19) is supported without play, the edge-open cutout 25 encloses the shaft of the door closer system shown, which is indicated in FIG. 3 and emerges from the cover 19 upwards. The U-shaped stop rib 11 engages around a projection provided on the end face of the door closer housing 26 which is visible in FIG. 3 and thereby creates a form-fitting connection between the hood holder 1 and the door closer housing 26.

Wie insbesondere aus Fig. 4 hervorgeht, sorgen nicht zuletzt die Positionierarme 15, 16 für eine sichere Abstützung der Abdeckhaube 19 an dem Haubenhalter 1. Darüber hinaus bewirken die Positionierarme 15, 16 eine Selbstzentrierung von Abdeckhaube 19 und Haubenhalter 1 relativ zueinander. Gleichwohl läßt sich auch ohne die Positionierarme 15, 16 ein funktionstüchtiger Haubenhalter realisieren.As can be seen in particular from FIG. 4, the positioning arms 15, 16 not least ensure that the covering hood 19 is securely supported on the hood holder 1. In addition, the positioning arms 15, 16 cause the covering hood 19 and the hood holder 1 to self-center relative to one another. Nevertheless, a functional hood holder can also be implemented without the positioning arms 15, 16.

Zur Demontage läßt sich die in Einbaulage gehaltene Abdeckhaube 19 gemeinsam mit dem daran formschlüssig befestigten Haubenhalter 1 in Richtung des Pfeiles B gemäß Fig. 4 von dem Türschließergehäuse 26 abziehen. Auch bei dieser Gelegenheit wirken die im Querschnitt zylindrischen Enden der Rastzungen 13, 14 reibungsvermindernd.For disassembly, the cover 19, which is held in the installed position, can be pulled off from the door closer housing 26 together with the hood holder 1 which is positively attached thereto in the direction of arrow B according to FIG. 4. On this occasion too, the ends of the latching tongues 13, 14, which are cylindrical in cross section, have a friction-reducing effect.

Als Haltefedern dienende Rastzungen 13a, 14a einer Haubenhalter-Bauform, die beim Abnehmen der Abdeckhaube 19 zusätzliche Demontagemaßnahmen erforderlich machen, sind in Fig. 4 gestrichelt angedeutet. Die Rastzungen 13a, 14a sind verglichen mit den Rastzungen 13, 14 unter einem größeren Winkel gegen die Horizontale gegeneinander geneigt. Infolgedessen sperren die Rastzungen 13a, 14a den betreffenden Haubenhalter und somit auch die damit über den an der Riegelzunge vorgesehenen Rastzapfen formschlüssig verbundene Abdeckhaube 19 gegen ein Abziehen in Richtung des Pfeiles B. Zur Demontage der Abdeckhaube 19 ist daher zunächst mit Hilfe eines Hilfsmittels, beispielsweise eines Schraubendrehers, die Formschlußverbindung zwischen der Abdeckhaube 19 und dem Haubenhalter zu lösen. Zu diesem Zweck läßt sich der in die Rastaufnahme 22 der Abdeckhaube 19 eingreifende Rastzapfen so weit in das Haubeninnere zurückdrücken, bis er die Abdeckhaube 19 freigibt. Nunmehr kann die Abdeckhaube 19 in Richtung des Pfeiles B abgezogen werden. Der Haubenhalter verbleibt, an dem Türschließergehäuse 26 über die Rastzungen 13a, 14a abgestützt, in seiner Einbaulage und läßt sich nach dem Entfernen der Abdeckhaube 19 von dem Türschließergehäuse 26 in dessen Längsrichtung abziehen. Eine unbefugte Demontage der Abdeckhaube 19 etwa an Türschließer-Anlagen in öffentlichen Gebäuden, wird zum Schutze der Anlage gegen Vandalismus durch die beschriebene Ausführungsform des Haubenhalters erheblich erschwert.Locking tongues 13a, 14a of a hood holder design, which serve as retaining springs and which make additional dismantling measures necessary when the cover hood 19 is removed, are indicated by dashed lines in FIG. 4. The latching tongues 13a, 14a are inclined relative to the latching tongues 13, 14 at a larger angle with respect to the horizontal. As a result, the locking tongues 13a, 14a lock the hood holder in question and thus also the cover 19 connected in a form-fitting manner via the locking pin provided on the locking tongue against pulling in the direction of the arrow B. To remove the cover 19, therefore, first of all with the aid of an aid, for example one Screwdriver to release the positive connection between the cover 19 and the hood holder. For this purpose, it can be inserted into the catch 22 of the cover 19 pushing the locking pin back into the interior of the cover until it releases the cover 19. Now the cover 19 can be removed in the direction of arrow B. The hood holder, supported on the door closer housing 26 via the latching tongues 13a, 14a, remains in its installed position and can be pulled off the door closer housing 26 in its longitudinal direction after the cover hood 19 has been removed. Unauthorized dismantling of the cover hood 19, for example on door closer systems in public buildings, is made considerably more difficult by the described embodiment of the hood holder in order to protect the system against vandalism.
