Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Anschlußvorrichtung für ein Wandheizgerät nach der Gattung des Hauptanspruchs. Bei Anschlußvorrichtungen dieser Gattung ist wegen des Freiraums zwischen Montageplatte und Installationswand eine verhältnismäßig freizügige Anordnung der bauseitigen Anschlußstutzen an der Montageplatte möglich. Dagegen muß die Lage der geräteseitigen Anschlußstützen der Montageplatte eng toleriert auf die Anordnung der entsprechenden Anschlüsse an dem zu installierenden Heizgerät abgestimmt sein. Das bedingt in vielen Fällen eine versetzte Anordnung der geräteseitigen Anschlußstutzen gegenüber den Durchflußöffnungen, die bei bekannten Anordnungen durch die Zwischenschaltung von Fittings und dergleichen Rohrstücke erreicht wird. Das erhöht den Fertigungsaufwand und erschwert unter Umständen eine Anpassung der Montageplatte an unterschiedliche Heizgerätetypen, wenn eine vorgegebene Anordnung der bauseitigen Anschlußstutzen und der Durchflußöffnungen in der Montageplatte beibehalten werden soll. The invention relates to a connection device for Wall heater according to the genus of the main claim. At Connection devices of this type is because of the free space between mounting plate and installation wall relatively permissive arrangement of the on-site Connection piece possible on the mounting plate. Against that the location of the device side connection supports Mounting plate closely tolerated on the arrangement of the corresponding connections on the to be installed Heater must be matched. In many cases, this requires one staggered arrangement of the device-side connection piece compared to the flow openings that in known Arrangements through the interposition of fittings and the same pipe pieces is reached. That increases the Manufacturing effort and may make it difficult Adaptation of the mounting plate to different Heater types if a given arrangement of on-site connecting piece and the flow openings in the mounting plate should be retained.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Anordnung mit den Merkmalen des Hauptanspruchs ergibt eine platzsparende und kostengünstige Ausführung, bei welcher die geräteseitigen Anschlußstutzen ohne Platz beanspruchende Verbindungselemente in weiten Grenzen freizügig gegenüber den korrespondierenden Durchflußöffnungen der Montageplatte angeordnet werden können.The arrangement according to the invention with the features of The main claim results in a space-saving and inexpensive Version in which the device-side connection piece without connecting elements that take up space Boundaries open to the corresponding ones Flow openings of the mounting plate are arranged can.

Durch die in den Unteransprüchen aufgeführten Merkmale sind vorteilhafte Ausgestaltungen und Weiterbildungen der Anordnung nach dem Hauptanspruch möglich.By the features listed in the subclaims advantageous refinements and developments of Arrangement possible according to the main claim.

Bei Anschlußvorrichtungen, die mit Ventilen zum Öffnen und Schließen der Wasserdurchführungen versehen sind, ergibt sich eine einfache Ausführung, wenn das oder die schalenartig ausgebildeten Formteile koaxial zu der von ihr überdeckten Durchgangsöffnung einen Anschlußstutzen für das Oberteil eines die Durchflußöffnung überwachenden Ventils tragen. Dadurch entfallen besondere Ventilgehäuse und die allein benötigten Ventil-Oberteile können für alle Wasserdurchführungen einheitlich ausgebildet sein.For connecting devices with valves for opening and Closing the water ducts are provided a simple run if that or that shell-like molded parts coaxial to that of her covered through opening a connecting piece for the Upper part of a valve monitoring the flow opening carry. This eliminates special valve housings and Valve tops alone required can be used by everyone Water feedthroughs should be uniform.

Bei Anschlußvorrichtungen, die eine die Kaltwasserleitung mit einer der Leitungen des Heizungsnetzes korrespondierende Verbindungsleitung haben, welche über eine Ventilanordnung (disconnecteur) führt, wird vorgeschlagen, daß auch die bauseitigen Anschlußstutzen für Kaltwasser und für die eine der Leitungen des Heizungsnetzes an einem schalenförmig ausgebildeten Formteil befestigt sind, der sich sowohl über die dem Anschlußstutzen zugeordnete Durchflußöffnung als auch über eine daneben vorgesehene, in die Verbindungsleitung führende Öffnung in der Montageplatte erstreckt. In connection devices, the one the cold water pipe corresponding to one of the lines of the heating network Have connecting line, which via a valve arrangement (disconnecteur), it is proposed that the on-site connecting piece for cold water and for one the cables of the heating network on a bowl trained molded part are attached, which both over the flow opening assigned to the connecting piece as also via an adjacent, in the Connection line leading opening in the mounting plate extends.

Wenn auch der Eingang und/oder der Ausgang der Verbindungsleitung durch ein Ventil überwacht sein soll, ergibt sich eine kostengünstige Ausführung, wenn die entsprechende, in die Verbindungsleitung führende Öffnung in der Montageplatte auf deren Geräteseite von einem schalenartig ausgebildeten Formteil überdeckt ist, das einen koaxial zur Öffnung angeordneten Anschlußstutzen für das Oberteil eines die Öffnung überwachenden Ventils und daneben einen Anschlußstutzen für die Verbindungsleitung trägt.If also the entrance and / or the exit of the Connecting line should be monitored by a valve, the result is an inexpensive version if the corresponding opening in the connecting line in the mounting plate on the device side of one shell-like molded part is covered, the one Coaxial to the opening connector for the Upper part of a valve monitoring the opening and next to it carries a connecting piece for the connecting line.

Die auf einer Seite der Montageplatte angeordneten, die Anschlußstutzen tragenden Formteile können einstückig miteinander zu einer Platte mit einer der Anzahl der Anschlußstutzen entsprechenden Zahl von schalenartigen Vertiefungen vereinigt sein. Bei eng nebeneinanderliegenden Durchflußöffnungen kann es aber auch zweckmäßig sein, jedes Formteil für sich als Einzelteil auszubilden und an der Montageplatte zu befestigen.The arranged on one side of the mounting plate, the Connection pieces supporting molded parts can be in one piece with each other into a plate with one of the number of Connection piece corresponding number of shell-like Be deepened. With close to each other Flow openings, but it can also be appropriate, each Form part for itself as a single part and on the Fix mounting plate.
