- b) als Fahrzeugboden dient ein wärmedurchlässiger Belag, undb) serves as the vehicle floor a heat-permeable covering, and
- c) der untere Bodenteil ist mit in Richtung der Unterseite der Rinnen hochragenden Absätzen, z. B. in Form herausgedrückter Warzen versehen, über die nur eine örtliche Verbindung mit den Rinnen zu deren Abstützung erfolgt.c) the lower bottom part is in the direction of the bottom of the Gutters towering heels, e.g. B. pressed out in the form Warts provided only with a local connection the gutters are used to support them.
Eine große Tragfähigkeit und damit die Möglichkeit zum Einsatz einer vor montierten Baugruppe ist gegeben, wenn der Isolierstoff aus Polyurethan-Schaum besteht, der auch die seitlich durch die Absätze begrenzten Zwischenräume unterhalb der Unterseite der Rinnen ausfüllt.A large load capacity and thus the possibility of using a front Assembled assembly is given when the insulating material is made Polyurethane foam is made, which is also through the side Paragraphs delimited spaces below the bottom of the Fills in gutters.
Beim Einsatz der erfindungsgemäßen Fahrgastraumheizung in einem Großraumfahrzeug, insbesondere Omnibus ist eine Anhebung der Heizleistung auf einfache Weise dadurch möglich, daß auch in senkrecht verlaufenden Abschnitten des Fahrzeugbodens und/oder der Seitenwand Rinnen mit darin eingelassenen Rohren zu Heiz zwecken angeordnet sind.When using the passenger compartment heater according to the invention in one Large vehicle, especially omnibus, is an increase in Heating power possible in a simple manner that also in vertical sections of the vehicle floor and / or the side wall gutters with pipes embedded in them for heating are arranged for purposes.
Der Gegenstand der Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigtThe subject matter of the invention is described in the following in the drawing illustrated embodiment explained in more detail. In the drawing shows
Fig. 1 einen Querschnitt eines Bodenbereiches eines Omnibusses, Fig. 1 shows a cross section of a bottom portion of a bus,
Fig. 2 einen Schnitt nach der Linie II-II in Fig. 1 und Fig. 2 shows a section along the line II-II in Fig. 1 and
Fig. 3 einen Schnitt durch einen fensternahen Seitenwand bereich des gleichen Fahrzeuges. Fig. 3 shows a section through a window near the side wall area of the same vehicle.
Ein in Fig. 1 im Schnitt dargestellter Fahrzeugboden 1 eines nicht näher dargestellten Omnibusses weist einen etwa waage recht verlaufenden Abschnitt 2 auf, an den sich ein etwa senkrecht verlaufender Abschnitt 3 anschließt, der unter Bildung einer Stufe in einen weiteren, wiederum etwa waage recht verlaufenden Abschnitt 4 übergeht. Der Abschnitt 2 stellt dabei einen Teil des Mittelganges dar, während der stufenförmig abgesetzte Abschnitt 4 die Bestuhlung aufnimmt, wobei in nicht näher dargestellter Weise der dem Abschnitt 2 zugekehrte Fuß 5 des Stuhles durch Klammern 6 an einer Profilschiene 7 gehalten wird.A a bus not shown in Fig. 1 shown in the sectional vehicle floor 1 has a right extending approximately horizontally extending section 2, to which an approximately vertically extending portion 3 adjoins the horizontal to form a stage in a further turn about Section 4 merges. The section 2 represents part of the central aisle, while the stepped section 4 accommodates the seating, the foot 5 of the chair facing the section 2 being held in a manner not shown by clips 6 on a profile rail 7 .
In den verschiedenen Abschnitten des Fahrzeugbodens 1 sind Rinnen 8 eingelassen, deren schellenartig auslaufende Flansche 9 von unten her am Fahrzeugboden 1 anliegen und mit diesem verbunden sind. Die Unterseite 10 der Rinnen 8 liegt auf Absätzen 11 auf, die in Form von Warzen im Abstand vonein ander aus einem unteren Bodenteil 12 herausgeformt sind, wie dies insbesondere der Fig. 2 zu entnehmen ist. Ein aus Poly urethan-Schaum bestehender Isolierstoff 13 füllt sowohl den Hohlraum 14 zwischen den Rinnen 8, als auch die Zwischenräume 15 (Fig. 2) zwischen den Ansätzen 11 aus, so daß sich eine Art Sandwich-Struktur mit guter Trageigenschaft ergibt. In the different sections of the vehicle floor 1 there are recesses 8 , the flanges 9 of which extend in a clamp-like manner from below and are connected to the vehicle floor 1 . The underside 10 of the channels 8 rests on shoulders 11 , which are formed in the form of warts at a distance from one another from a lower base part 12 , as can be seen in particular in FIG. 2. A poly urethane foam insulating material 13 fills both the cavity 14 between the channels 8 , as well as the spaces 15 ( Fig. 2) between the lugs 11 , so that there is a kind of sandwich structure with good wearing properties.
Von den Rinnen 8 werden Rohre 16 aus einem elastischen Material aufgenommen, die mit mindestens der Hälfte ihres Umfanges an der Rinnenwandung 17 anliegen, wodurch ein guter Wärmeübergang erreicht wird. Ein wärmedurchlässiger Belag 18, z. B. Teppichboden, deckt die Rinnen 8 nach oben hin ab und bildet auch gleichzeitig die übrige Außen schicht des Fahrzeugbodens 1.Tubes 16 made of an elastic material are accommodated by the channels 8 , which bear against the channel wall 17 with at least half their circumference, as a result of which good heat transfer is achieved. A heat-permeable covering 18 , e.g. B. carpet, covers the channels 8 towards the top and also forms the remaining outer layer of the vehicle floor 1 .
Wie aus Fig. 3 ersichtlich, sind zur Erhöhung des Komforts auch in einer Seitenwand 19 unterhalb eines Seitenfensters 20 Rinnen 8 angeordnet, die in bereits beschriebener Weise abgestützt sind und Rohre 16 aufnehmen. Diese Rinnen 8 sind durch einen wärmedurchlässigen, auch den angrenzenden Wand bereich bedeckenden, als Verkleidungsteil ausgebildeten Be lag 18 abgedeckt.As can be seen from FIG. 3, 20 channels 8 are arranged in a side wall 19 below a side window in order to increase comfort, which are supported in the manner already described and accommodate tubes 16 . These channels 8 are covered by a heat-permeable, also covering the adjacent wall area, designed as a covering part 18 .
Die in nicht dargestellter Weise untereinander verbundenen Rohre 16 gemäß der Anordnung nach Fig. 1 und 2, sowie nach Fig. 3 werden nach dem Einfügen der vorzugsweise als vormontierte Baueinheit gefertigten Abschnitte in den Fahr zeugaufbau lediglich an den Heizmittelkreislauf angeschlossen.The pipes 16, which are not interconnected in accordance with the arrangement according to FIGS. 1 and 2, and also according to FIG. 3, are only connected to the heating medium circuit after the insertion of the sections, which are preferably manufactured as a pre-assembled unit, into the vehicle.
