Abstract

A snap-on hinged cover for equipment ranges has the advantage of being quickly and easily snapped onto the equipment only after complete installation of the equipment so that the required freedom for mounting the equipment is ensured and access to the connecting screws is not prematurely blocked. The snapping point of the hinged cover on the equipment is clearly determined by contours on the inner side of the cover which are laid on complementary bearing faces on the base body of the equipment. Movable elastic tongues formed on the hinged cover and provided with bearing pins allow the latter to be quickly and easily snapped into recesses on the housing bearing face.

Description

"Aufrastbarer Klappdeckel" "Snap-on hinged lid"
BESCHREIBUNGDESCRIPTION
Die vorliegende Erfindung betrifft einen aufrastbaren Klapp¬ deckel für Installationsgeräte nach dem Oberbegriff des Pa¬ tentanspruchs 1.The present invention relates to a snap-on hinged cover for installation devices according to the preamble of claim 1.
Klappdeckel finden vielfältige Verwendung in den verschieden¬ sten Installationsgerätesortimenten. So werden Gerätesorti¬ mente mit schließbarem Klappdeckel beispielsweise für Instal¬ lationen in feuchten Räumen, für Installationen, deren Geräte¬ sortimente vor Staub bzw. Schlag geschützt werden sollen oder bei denen Klappdeckel der Zugriffssicherung' durch nichtbefugte Personen, hier sei insbesondere an den Zugriff durch Kinder¬ hände gedacht, dienen sollen. Diese Installationsgerätesorti¬ mente sehen nicht nur Einfach-, sondern auch Zwei- und Mehr¬ fachkombinationen von Installationsgeräten mit schließbaren Klappdeckeln vor.Hinged covers are used in a wide variety of different installation device ranges. Thus, device ranges with closable hinged covers are used, for example, for installations in damp rooms, for installations whose device ranges are to be protected against dust or shock or for which hinged covers are used to prevent access by unauthorized persons, in particular here by access Children's hands thought to serve. These installation device ranges provide not only single, but also double and multiple combinations of installation devices with closable hinged covers.
Installationsgeräte mit Klappdeckeln werden üblicherweise so montiert, daß der Einsatz, also das Gehäuseoberteil, verdrahtet wird und anschließend in verdrahteter Form in das Gehäuseunterteil eingesetzt und mit diesem verschraubt wird. Da üblicherweise die Klappdeckel an den zu verdrahtenden Geräteoberteilen vormontiert sind, ist es notwendig, beim Aufschrauben des verdrahteten Geräteoberteiles auf das Gerätunterteil den jeweiligen Klappdeckel geöffnet zu halten, um die in den Bohrungen des Geräteoberteiles eingelassenen Schrauben zum Verbinden mit dem Geräteunterteil frei zugänglich zu gestalten und um Montagefreiheit zu r gewährleisten. Da es eine Voraussetzung des Technischen Uberwachungsvereines ist, daß bei ausgewählten Geräte¬ sortimenten die Klappdeckel so f derbelastet sein müssen, daß sie selbsttätig schließen, isτ es für den Monteur recht aufwendig, gleichzeitig die Schraubverbindung des verdrahteten Geräteoberteiles herzustellen und den Klappdeckel geöffnet zu halten. Umständlich und zeitraubend auch deshalb, da Installa¬ tionsgeräte ja nicht ausschließlich an leicht zugänglichen und montagefreundlichen Stellen befestigt werden müssen.Installation devices with hinged lids are usually installed in such a way that the insert, i.e. the upper part of the housing, is wired and then inserted in wired form into the lower part of the housing and screwed to it. Since the hinged covers are usually preassembled on the upper parts of the device to be wired, it is necessary to keep the respective hinged covers open when screwing the wired upper part of the device onto the lower part of the device in order to make the screws in the holes in the upper part of the device freely accessible for connection to the lower part of the device and to ensure freedom of assembly r ensure. Since it is a prerequisite of the Technical Surveillance Association that the hinged covers of selected device ranges must be so loaded that they close automatically, it is quite expensive for the fitter to simultaneously produce the screw connection of the wired upper part of the device and to keep the hinged cover open. It is also cumbersome and time-consuming, since installation devices do not have to be attached exclusively to easily accessible and assembly-friendly locations.
Ausgehend von diesem Stand der Technik ist es die Aufgabe der vorliegenden Erfindung, Klappdeckel für Installationsgeräte¬ sortimente zu schaffen, die ungehinderte Montagefreiheit beim Verbinden des verdrahteten Gehäuseoberteiles mit dem Gehäuse¬ unterteil gewährleisten, deren Verbindungsschrauben frei zu- gänglich sind und die trotzdem den Anforderungen, die an durch Klappdeckel verschlossene Installationsgeräte gestellt werden, genügen .Based on this prior art, it is the object of the present invention to provide hinged covers for installation device ranges which ensure unhindered freedom of assembly when connecting the wired upper housing part to the lower housing part, the connecting screws of which are freely accessible and which nevertheless meet the requirements, which are placed on installation devices closed by hinged covers are sufficient.
Diese Aufgabe wird durch einen aufrastbaren Klappdeckel nach der Lehre des Patentanspruchs 1 gelöst. Weitere Ausgestaltun- gen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a snap-on hinged lid according to the teaching of claim 1. Further embodiments of the invention are the subject of the dependent claims.
Der aufrastbare Klappdeckel gemäß der vorliegenden Erfindung weist am Klappdeckel angeformte federnde Zungen auf, die ih¬ rerseits Lagerzapfen tragen, die in Bohrungen am Gerätege¬ häuse, also am Gehäuseoberteil einrastbar sind.The snap-on hinged lid according to the present invention has resilient tongues formed on the hinged lid, which in turn carry bearing pins which can be snapped into bores in the device housing, that is to say on the upper housing part.
Im einfachsten Fall weist der aufrastbare Klappdeckel an sei¬ ner Deckelinnenseite, der durch die Lagerzapfen definierten Klappachse paralell gegenüberliegend, vom Deckelrand leicht beabstandet eine durchgängige Kontur in Form einer Querrippe au .In the simplest case, the snap-on hinged lid has a continuous contour in the form of a transverse rib on its inside, parallel to the hinged axis defined by the bearing pins, slightly spaced from the lid edge.
Diese Kontur des Klappdeckels ist im einfachsten Fall an eine Querrippe des Gehäuseoberteiles, welches hier1 als Gegenlager fungiert , anlegbar und fixiert so den Einrastpunkt des Klapp¬ deckels auf dem Gehäuse. Zum Einrasten des Klappdeckels wird die Kontur, Querrippe des Deckels an ein Gegenlager am Gehäuse, eine Querrippe des Ge¬ häuses angelegt, so daß der Klappdeckel genau auf dem Einrast¬ punkt fixiert ist und ein umständliches Suchen des Einrast- punktes vermieden wird. Der derart fixierte Klappdeckel ist nun einfach einrastbar. Es ist lediglich ein leichter Druck auf die die Lagerzapfen tragenden Deckelecken notwendig, um die Lagerzapfen in die vorgesehenen Bohrungen im Gehäuseober¬ teil einrasten zu lassen. Vorraussetzung für ein leichtes Ein- rasten des Deckels sind die beweglich, insbesondere an federn¬ den Zungen angeformten Lagerzapfen. Diese neigen sich beim Druck auf den Klappdeckel leicht in Richtung Deckelinnenseite und geben dabei den benötigten Einrastweg frei. Die federnden Zungen sind im wesentlichen rechtwinklig zur Klappdeckelober- fläche, seitlich am Klappdeckel angeformt und erstrecken sich im wesentlichen über die äußere Klappdeckelstruktur hinaus.This contour of the hinged lid is in the simplest case a transverse rib of the upper housing portion which acts as a counter bearing 1 herein, can be applied and fixed to the locking point of the Klapp¬ lid on the housing. To lock the hinged cover, the contour, transverse rib of the cover is placed on a counter bearing on the housing, a transverse rib of the housing, so that the hinged cover is fixed exactly on the latching point and a laborious search for the latching point is avoided. The hinged lid fixed in this way can now easily be snapped into place. All that is necessary is a slight pressure on the corners of the cover carrying the journal to snap the journal into the holes provided in the upper part of the housing. A prerequisite for the cover to snap in easily is the movable bearing pins, in particular molded onto spring-loaded tongues. When the hinged lid is pressed, these incline slightly towards the inside of the lid, thereby releasing the required snap-in travel. The resilient tongues are formed essentially at right angles to the surface of the hinged cover, laterally on the hinged cover, and extend essentially beyond the outer structure of the hinged cover.
Die federnden Zungen können verschieden ausgeführt sein, ins¬ besondere erstrecken sie sich nach Art eines Rechteckes mit abgerundeten Ecken, seitlich am Klappdeckel in Richtung Gerä- tegehäuse. Zur Unterstützung der federnden Biegsamkeit sind die federnden Zungen nach einer bevorzugten Ausführungsform durch verschieden tiefe Ausnehmungen von den den Klappdeckel umlaufenden, abgewinkelten Außenkonturen abgeschnürt.The resilient tongues can be designed differently, in particular they extend in the manner of a rectangle with rounded corners, on the side of the hinged cover, in the direction of the device housing. To support the resilient flexibility, the resilient tongues are pinched off according to a preferred embodiment by recesses of different depths from the angled outer contours surrounding the hinged cover.
Der aufrastbare Klappdeckel weist an seiner Deckelinnenseite Konturen in Form von Zapfen, Nasen, Rippen auf, die sich in Richtung Gerätegehäuse, mit unterschiedlicher Ausdehnung, er¬ strecken, wobei sie mit mindestens einem auf dem Gerätegehäuse an oder eingeformten Gegenlager in Anlage kommen. Die sich aus der Deckelinnenseite heraus erstreckenden Konturen sind im we- sentlichen parallel zu der durch die Lagerzapfen des Klapp¬ deckels definierten Klappachse angeordnet. Die Konturen können dabei durchgängig einstückig ausgeführt sein oder mehrstückig voneinander beabstandet ausgebildet und an der Deckelseite in¬ nen angeordnet sein. Wesentlich ist jedoch, daß mindestens eine Kontur an der Deckelseite innen so angeordnet ist, daß sie mit mindestens einem Gegenlager am Gerätegehäuse in Anlage kommt, um einen stabilen Einrastpunkt des Klappdeckels zu de- finieren. Am Gerätegehäuse selbst sind Gegenlager ein- oαer mehrstückig, senkrecht vom Gerätegehäuse hervorspringend ange¬ ordnet, die in Verbindung mit den Konturen des Deckels die Lage des Klappdeckels so genau definieren, daß ein Einrasten der Lagerzapfen in die dafür vorgesehene Bohrung durch Druck auf den Klappdeckel mit Sicherheit bewirkt wird.The snap-on hinged lid has contours in the form of pegs, lugs, ribs on the inside of the lid, which extend in the direction of the device housing with different dimensions, whereby they come into contact with at least one counter bearing that is molded onto the device housing. The contours extending from the inside of the cover are arranged essentially parallel to the folding axis defined by the bearing pins of the folding cover. The contours can be made in one piece or spaced apart from one another and can be arranged on the inside of the cover. It is essential, however, that at least one contour on the inside of the cover is arranged in such a way that it comes into contact with at least one counter bearing on the device housing in order to determine a stable engagement point of the hinged cover. finish. On the device housing itself, counter bearings are arranged in one piece, projecting vertically from the device housing, which, in conjunction with the contours of the cover, define the position of the hinged lid so precisely that the bearing pins snap into the bore provided for this purpose by pressing on the hinged lid Security is effected.
Die Gegenlager am Gerätegehäuse können neben den senkrecht vom Gerätegehäuse hervorspringenden Rippen, Nasen oder Zapfen auch durch im Gerätegehäuse eingeformte Ausnehmungen gebildet wer- den.In addition to the ribs, lugs or pins protruding vertically from the device housing, the counter bearings on the device housing can also be formed by recesses formed in the device housing.
Voraussetzung für ein sicheres Einrasten des Klappdeckels mit Gegenlagern in Form von Ausnehmungen ist selbstverständlich, daß die zugehörige Deckelkontur entsprechend weiter von der Deckelinnenseite in Richtung Gerätegehäuse hervorspringt, so daß ein Eingreifen der Deckelkontur in die Gerätegehäuseaus- nehmung gewährleistet wird und damit eine genaue Lagedefini¬ tion des einzurastenden Deckels sichergestellt ist.A prerequisite for a secure latching of the hinged lid with counter bearings in the form of recesses is of course that the associated lid contour protrudes correspondingly further from the inside of the lid towards the device housing, so that an engagement of the lid contour in the device housing exception is ensured and thus an exact position definition of the lid to be locked is ensured.
Als Gegenlager des Gerätegehäuses kann in ebenfalls einer ein¬ fachsten Ausführung die Kontur der Deckelinnenseite an ein vorhandenes Formelement des Gerätegehäuses anschlagen. Möglich wäre hier, und besonders vorteilhaft, das Anschlagen der Deckelinnenkontur an die die Schutzkontaktezungen aufnehmenden Formteile der Steckereinstecksöffnung .As a counter bearing of the device housing, the contour of the inside of the cover can also strike a given shaped element of the device housing in a simplest embodiment. It would be possible, and particularly advantageous, to strike the inner contour of the cover against the molded parts of the plug insertion opening that receive the protective contact tongues.
Der aufrastbare Klappdeckel wird ebenfalls durch die federnden Zungen, die beidseitig am Klappdeckel angeordnet sind und die Lagerzapfen tragen, im Gerätegehäuse geführt. Die Führung des Klappdeckels erfolgt insbesondere durch vom Gehäuse aufstrebende, die Gehäuseoberfläche zumindest teilweise überragende Deckelaufnahmelager. In diesen Deckelaufnahme- lagern sind Ausnehmungen zur Aufnahme der an den federnden Zungen angeformten Lagerzapfen.The snap-on hinged cover is also guided in the device housing by the resilient tongues which are arranged on both sides of the hinged cover and which support the bearing pins. The hinged cover is guided, in particular, by cover receiving bearings which emerge from the housing and at least partially project beyond the housing surface. In these cover receiving bearings there are recesses for receiving the bearing pins formed on the resilient tongues.
Das Aufrasten des Klappdeckels erfolgt nunmehr nach der ferti¬ gen Montage des Gehäuses, also nach dem Aufschrauben des ver¬ drahteten Gehäuseoberteiles auf das Gehäuseunterteil. Der auf- rastbare Deckel bietet insofern den Vorteil, daß die Gehäuse- Oberteile nicht vormontiert werden müssen. Mit anderen Worten. Gerätegehäuse und Klappdeckel werden getrennt voneinander ge¬ liefert. Nach der vollständigen Montage, die den großen Vorteil der freien Zugänglichkeit der Verbindungselemente, insbesondere also der freien Zugänglichkeit zu den Schrauben gewährleistet, erfolgt ein Aufrasten des Klappdeckels. Dazu wird in auf der Deckelinnenseite angeformte Aufnahmeform¬ elemente, die auf der durch die Lagerzapfen definierten Klappachse liegen, ein Federelement eingebracht. Anschließend wird der Klappdeckel mit einer seiner Konturen gegen ein auf der Gehäuseoberfläche angeformtes Gegenlager angeschlagen und so der Einrastpunkt des Klappdeckels, insbesondere der Lagerzapfen zu den in den Gehäuselagern befindlichen Ausnehmungen fixiert. Eine seitliche Führung des Klappdeckels erfolgt insbesondere durch federnde Zungen, die am Deckel angeformt sind und mit den Aufnahmelagern für die Lagerzapfen, die an der Gehäuseoberfläche ang'eformt sind, in Anlage kommen. Eine seitliche Führung des Klappdeckels zur weiteren Fixierung des Einrastpunktes kann ebenfalls durch winklig an die parallel zur Klappachse verlaufenden Konturen angeordneteThe hinged cover is now snapped on after the finished assembly of the housing, that is to say after the wired upper housing part has been screwed onto the lower housing part. The snap-on cover offers the advantage that the housing Upper parts do not have to be pre-assembled. In other words. Device housing and hinged cover are delivered separately from each other. After the complete assembly, which ensures the great advantage of the free accessibility of the connecting elements, in particular thus the free accessibility to the screws, the hinged cover is snapped on. For this purpose, a spring element is introduced into the molded receptacle elements formed on the inside of the lid, which lie on the folding axis defined by the bearing pins. The hinged cover is then struck with one of its contours against a counter bearing formed on the housing surface, and thus the snap-in point of the hinged cover, in particular the bearing pin, is fixed to the recesses in the housing bearings. Lateral guidance of the hinged cover is carried out in particular by resilient tongues which are formed on the cover and come into contact with the receiving bearings for the bearing journals which are integrally formed on the housing surface. Lateral guidance of the hinged cover for further fixing of the snap-in point can also be arranged at an angle to the contours running parallel to the hinged axis
Führungselemente , die mit Formelementen des Gerätegehäuses in Eingriff gelangen, fixiert werden. Möglich ist auch eine seitliche Deckelführung durch nach oben gezogene, die Gehäuseoberfläche überragende Gehäuseseitenteile oder durch Verlängerung der die Lagerzapfen aufnehmenden Gehäuselager in Richtung der Seitenflächen des Gehäuseoberteiles. Der nach dieser Art auf dem Gerätegehäuse genau über dem Einrastpunkt der Lagerzapfen fixierte Lagerdeckel ist nunmehr durch leichten Druck auf den Deckel, im Bereich der durch die Lagerzapfen definierten Klappachse, insbesondere an beiden Deckelseiten auf einfache und schnelle Art im Gerätegehäuse einrastbar.Guide elements that come into engagement with molded elements of the device housing are fixed. It is also possible for the cover to be guided laterally by upwardly drawn housing side parts projecting above the housing surface or by extending the housing bearings receiving the bearing journals in the direction of the side surfaces of the upper housing part. The bearing cover fixed in this way on the device housing exactly above the snap-in point of the bearing journal can now be snapped into the device housing in a simple and quick manner by light pressure on the cover, in the region of the folding axis defined by the bearing journal, in particular on both cover sides.
Im folgenden wird die Erfindung anhand eines Ausführungsbei¬ spiels in Verbindung mit den beiliegenden Zeichnungen näher erläutert.The invention is explained in more detail below with the aid of an exemplary embodiment in conjunction with the accompanying drawings.

This snap-on hinged cover has 1 pivot pin 6 on both sides of the hinged cover for locking the bearing cover on the device housing. Contours 2, 3, 4 extend on the inside of the bearing cover in the direction of the device housing. The contours 3 and 4 extend in wesentli hen parallel to the folding axis defined by the bearing pin 6. The contour 4 has the shape of a continuous rib which extends over the entire inside of the cover. The contours 3 are formed by two spaced apart ribs. The contour 2 also runs essentially parallel to the folding axis defined by the bearing pins, but has angularly shaped side contours, so that the contour 2 extends essentially U-shaped from the inside of the cover towards the device housing.

Zum Einrasten des Klappdeckels werden nach Fixierung des Klappdeckels auf dem Gerätegehäuse durch Anlegen von Kontur 4 an Gegenlager 4' unter leichtem Druck auf den Gehäusedeckel im Bereich der durch die Lagerzapfen 6 definierten Klappachse die Lagerzapfen 6 in die Ausnehmungen 8 der Gehäuselager 7 gedrückt. Durch Andrücken des Klappdeckels 1 werden die federnden Zungen 9 aus ihrer im wesentlichen rechtwinkligen Lage zum Klappdeckel in Richtung Deckel abgewinkelt und ermöglichen so den nötigen Freiraum, um die Lagerzapfen 6 am Gehäuselager 7 in die Ausnehmungen 8 im Gehäuselager einschnappen zu lassen. Hinged cover is struck against the counter bearing 4 ', which according to this preferred embodiment is formed by the transverse rib of the housing 5 which is present anyway. The contours 3 are placed against counter bearings 3 ', which are formed by two lugs protruding from the surface of the device housing. The contour 2 is placed against the counter bearing 2 ', which is formed by the molded part which in any case protrudes from the housing surface and receives the protective contact. According to this preferred embodiment, the lateral guidance of the snap-on hinged cover is fixed by the housing bearings 7 which extend over the entire device housing 5. Fig. 3 shows a snap-on hinged cover 1 with resilient tongues 9, on which the bearing pins 6 are integrally formed. The hinged lid in Fig. 3 has a contour 4 which is designed as a continuous transverse rib slightly spaced from the lid edge. To snap on the hinged lid, the lid 1 is placed with its contour 4 on the counter bearing 4 '. The counter bearing 4 'is formed by the front transverse rib of the device housing 5. To lock the hinged cover in place, after fixing the hinged cover to the device housing by applying contour 4 to counter bearing 4 ', with slight pressure on the housing cover in the area of the folding axis defined by the journals 6, the journals 6 are pressed into the recesses 8 of the housing bearings 7. By pressing the hinged cover 1, the resilient tongues 9 are angled out of their essentially rectangular position relative to the hinged cover in the direction of the cover and thus allow the necessary clearance to snap the bearing pins 6 on the housing bearing 7 into the recesses 8 in the housing bearing.
