Abstract

The door has an outer door leaf (1), an inner door surface (7), designed as a sheet-metal lining, and a foam insulation (6). The outer door leaf (1) and the inner door surface (7) are connected by narrow sides (2), the aluminium profiles of which engage around the edges of the outer door leaf and, together with a connecting profile of plastic (4), hold sealing profiles (5). In the case of known doors, the plastic profiles of the narrow sides also form the inner door edges, the flat sheet of the inner door surface (7) being pushed into a slit in the plastic profile. Problems are presented by the sensitivity of the inner door edge to rough treatment and the difficulty in securely sealing off the connecting point of the metal sheet with the plastic profile during foam filling. A door which is not sensitive in the inner edge region and is easy to manufacture can be realised by making the metal sheet of the inner door surface flanged where it goes over into the narrow sides (2), by welding respectively abutting metal sheets of the narrow sides of the door, forming an edge, to create an inner door shell (7), and by the door shell (7) being connected at the narrow sides (2) of the door to the connecting profile (4). <IMAGE>

Description

Die Erfindung betrifft eine Tür für einen Kühlcontainer mit einem sta­bilen, äußeren Türblatt, einer inneren, als Blechauskleidung ausgebil­deten Türfläche, mit das äußere Türblatt und die innere Türfläche ver­bindenden Schmalseiten, die als Profile die Kanten des äußeren Türblat­tes umgreifen und ein Anschlußprofil aus Kunststoff aufweisen und mit einer zwischen dem äußeren Türblatt und der inneren Türfläche befindli­chen Schaumstoffisolierung. Die Profile, die die Kanten des äußeren Türblatts umgreifen, werden wegen der Widerstandsfähigkeit im allgemei­nen aus Aluminium hergestellt. An diese schließt sich das der Verhinde­rung von Wärmebrücken dienende Anschlußprofil aus Kunststoff an. Es ist natürlich auch möglich, auch das die Kanten des äußeren Türblatts um­greifende Profil aus Kunststoff herzustellen, wobei dann dieses Profil und das Anschlußprofil zweckmäßig als einziges Kunststoffprofil ausge­bildet werden. Bei den bekannten Türen bilden die Kunststoffprofile der Schmalseiten auch die Innentürkante. Das Blech der inneren Tür­fläche ist dann als ebenes Blech in einen Schlitz in dem Kunststoff­profil eingeschoben. Diese Ausführungsart der Containertür ist nach­teilig, da bei rauher Handhabung die Kunststoffprofile häufig insbe­sondere in den Ecken beschädigt und aufgerissen werden. Außerdem sind die bekannten Türen beim Ausschäumen des Zwischenraumes zwischen dem äußeren Türblatt und der inneren Auskleidung schwer zuverlässig abzu­dichten. Die in die Schlitze in den Kunststoffprofilen eingeschobenen Bleche müssen vor allem im Eckbereich durch innen eingelegte Winkel­ vernieten gehalten und verstärkt werden. Trotzdem läßt sich bei den bekannten Türen nicht vermeiden, daß der Schaum immer wieder aus ir­gendwelchen Löchern austritt. Das Entfernen und Säubern der Außenflä­chen von Schaumresten ist eine aufwendige Arbeit.The invention relates to a door for a refrigerated container with a stable, outer door leaf, an inner door surface designed as sheet metal lining, with narrow sides connecting the outer door leaf and the inner door surface, which encompass the edges of the outer door leaf as profiles and have a connecting profile made of plastic and with a foam insulation located between the outer door leaf and the inner door surface. The profiles that surround the edges of the outer door panel are generally made of aluminum because of their resistance. This is followed by the plastic connecting profile used to prevent thermal bridges. It is of course also possible to also produce the profile from plastic encompassing the edges of the outer door leaf, in which case this profile and the connecting profile are expediently formed as the only plastic profile. In the known doors, the plastic profiles of the narrow sides also form the inside edge of the door. The sheet of the inner door surface is then inserted as a flat sheet in a slot in the plastic profile. This type of construction of the container door is disadvantageous, since the plastic profiles are often damaged and torn open, particularly in the corners, in the case of rough handling. In addition, the known doors are difficult to reliably seal when foaming the space between the outer door leaf and the inner lining. The metal sheets inserted into the slots in the plastic profiles must be inserted in the corner area, in particular through angles riveted and reinforced. Nevertheless, it cannot be avoided with the known doors that the foam always comes out of any holes. Removing and cleaning the outer surfaces of foam residues is a complex task.

Die Aufgabe der Erfindung wird darin gesehen, eine Tür für einen Kühl­container zu entwickeln, die im Eckbereich der Innenseiten der Tür unempfindlich und die fertigungsfreundlich ist.The object of the invention is seen in developing a door for a refrigerated container which is insensitive in the corner region of the inside of the door and which is easy to manufacture.

Erfindungsgemäß wird diese Aufgabe bei einer Tür für einen Kühlcon tainer der eingangs genannten Gattung dadurch gelöst, daß das Blech der inneren Türfläche abgekantet in die Schmalseiten übergeht, jeweils aneinanderstoßende, eine Kante bildende Bleche der Schmalseiten der Tür zu einer inneren Türschale verschweißt sind und daß die Türschale an den Schmalseiten der Tür mit dem Anschlußprofil umlaufend verbun­den ist. Dadurch, daß die Bleche abgekantet und verschweißt werden, entstehen vollkommen dichte und stoßunempfindliche Ecken und Kanten, welche Formstabilität haben und bei starker Stoßbelastung höchstens eingedrückt, jedoch nicht aufgerissen werden, so daß die Tür selbst im Falle der Beschädigung hinsichtlich der Gebrauchsfähigkeit unbe­einträchtigt bleibt. Das Austreten von Schaum beim Ausschäumen im Eckenbereich ist zuverlässig vermieden. Auch die Verbindungsstelle des Blechs mit dem Kunststoffprofil an den Schmalseiten der Tür ist gut abzudichten, da es sich hier um eine einzige, glatt umlaufende, lineare Dichtungsstelle handelt.According to the invention this object is achieved in a door for a Kühlcon tainer of the type mentioned in that the sheet of the inner door surface is folded into the narrow sides, each abutting, edge-forming sheets of the narrow sides of the door are welded to an inner door shell and that Door shell on the narrow sides of the door with the connection profile is connected all round. The fact that the sheets are folded and welded creates completely tight and shock-resistant corners and edges, which have dimensional stability and at most are pushed in under heavy impact loads, but are not torn open, so that the door remains unaffected in terms of usability in the event of damage. Leakage of foam when foaming in the corner area is reliably avoided. The connection point of the sheet with the plastic profile on the narrow sides of the door must also be sealed well, since this is a single, smooth, linear sealing point.

Im einzelnen kann die Erfindung wie folgt vorteilhaft ausgestaltet sein.In particular, the invention can be advantageously configured as follows.

Eine gut wirksame Abdichtung bei einfacher Verbindungsmöglichkeit der abgekanteten Schmalseiten des Bleches mit den Kunststoffprofilen kann dadurch erreicht werden, daß das Kunststoffprofil an der Verbindungs­stelle die Form einer Tasche mit einer auf der Innenseite vorsprin­genden Kante hat (Hinterschneidung) und das Blech an seiner Verbin­dungsstelle als Spreizfeder nach innen umgebogen ist und daß sich die Spreizfeder mit der Kante gegen den Grund der vorspringenden Kante der Tasche abstützt und das Blech mit seiner Außenfläche gegen die dem Vorsprung gegenüber liegenden Fläche der Tasche drückt. Durch ein­faches Eindrücken der Feder in die Tasche wird die Verbindung herge­stellt. Die Federkraft hält zu Beginn des Ausschäumens die Außenfläche dicht gegen die Tasche. Bei Druckerhöhung beim Schäumen wirkt der Innen­druck zusätzlich abdichtend und die Feder wirkt einem Ausweichen des Bleches durch die stabilisierende Wirkung entgegen.A good effective seal with a simple possibility of connecting the folded narrow sides of the sheet with the plastic profiles can be achieved in that the plastic profile at the connection point has the shape of a pocket with a protruding edge on the inside (undercut) and the plate at its connection point as an expansion spring is bent inside and that the spreading spring with the edge against the bottom of the projecting edge supports the bag and presses the outer surface of the sheet against the surface of the bag opposite the projection. The connection is made by simply pressing the spring into the pocket. The spring force holds the outer surface tight against the pocket at the beginning of the foaming process. If the pressure increases during foaming, the internal pressure also has a sealing effect and the spring counteracts the sheet from evading due to the stabilizing effect.

Die Kanten zwischen den Schmalseiten und der Innenseite der Tür sind zur Vermeidung von Stoßbeanspruchung vorteilhaft abgeschrägt.The edges between the narrow sides and the inside of the door are advantageously chamfered to avoid shock loads.

Im folgenden wird anhand einer Zeichnung ein Ausführungsbeispiel der Erfindung erläutert.An exemplary embodiment of the invention is explained below with reference to a drawing.

Die Figur zeigt einen Ausschnitt einer häufig eingesetzten Tür für einen Kühlcontainer im Schnitt.The figure shows a section of a frequently used door for a refrigerated container in section.

Die zweiflügelige, stirnseitig angeordnete Tür für einen Kühlcontainer hat ein äußeres stabiles Türblatt aus mehrschichtig verleimtem Sperr­holz 1 und eine innere, als Blechauskleidung ausgebildete Türfläche. Das äußere Türblatt 1 und die innere Türfläche sind durch Schmalseiten 2 verbunden, die als Aluminiumstrangpreßprofile 3 die Kanten des äuße­ren Türblatts 1 umgreifen und zusammen mit einem Anschlußprofil 4 aus PVC Dichtungsprofile 5 halten. Das Innere der Tür ist mit einer Schaum­stoffisolierung 6 ausgeschäumt. Das Blech der inneren Türfläche geht durch Abbiegen in die Schmalseiten 2 über. Jeweils aneinanderstoßende, zusammen mit der inneren Türfläche eine Ecke bildende schmale Seiten des Blechs sind miteinander verschweißt (nicht dargestellt). Die so entstandene innere Türschale 7 aus Blech ist an den Schmalseiten 2 der Tür mit dem Kunststoffprofil 4 verbunden. An der Verbindungsstelle hat das Kunststoffprofil 4 die Form einer Tasche 8. Diese hat eine vorspringende Kante 9, gegen die sich das Blech, dessen Rand als Spreiz­feder 10 nach innen umgebogen ist, abstützt. Die Spreizfeder drückt das Blech mit seiner Außenfläche gegen die dem Vorsprung gegenüberlie­gende Fläche 11 der Tasche 8. Die Kanten der inneren Türschale 7 zwi­schen den Schmalseiten 2 und der inneren Türfläche sind abgeschrägt 12. Die beiden Türflügel sind mit je vier an dem äußeren Türblatt 1 verschraubten Scharnieren 13 um einen Zapfen 14 schwenkbar am Container befestigt.The double-leaf door arranged on the front side for a refrigerated container has an outer stable door leaf made of multilayer glued plywood 1 and an inner door surface designed as sheet metal lining. The outer door leaf 1 and the inner door surface are connected by narrow sides 2 which, as aluminum extrusion profiles 3, grip around the edges of the outer door leaf 1 and hold them together with a connecting profile 4 made of PVC sealing profiles 5. The inside of the door is foamed with foam insulation 6. The sheet of the inner door surface turns into the narrow sides 2 by bending. Each of the narrow sides of the sheet metal that abut one another, together with the inner door surface, are welded to one another (not shown). The resulting inner door shell 7 made of sheet metal is connected to the plastic profile 4 on the narrow sides 2 of the door. At the connection point, the plastic profile 4 has the shape of a pocket 8. This has a projecting edge 9, against which the sheet metal, the edge of which is bent inwards as a spreading spring 10, is supported. The spreading spring presses the sheet metal with its outer surface against the surface 11 of the pocket 8 opposite the projection. The edges of the inner door shell 7 between the narrow sides 2 and the inner door surface are beveled 12. The two door leaves are each fastened to the container with four hinges 13 screwed to the outer door leaf 1 about a pin 14.

Dadurch, daß die Verbindungsstelle zwischen der inneren Türschale 7 und dem Anschlußprofil 4 auf den Schmalseiten 2 der Tür liegt, erhält man eine umlaufende Verbindungsstelle, die durch die federförmige Aus­gestaltung des Blechrandes und der Tasche 8 im Anschlußprofil 4 mon­tagefreundlich und gegen das Austreten von Schaum dicht ist. Die ver­schweißten Ecken der inneren Türschale 7 sind dicht und stoßunempfind­lich. Durch Oberschleifen sind sie an der Oberfläche glatt ausgeführt.Characterized in that the connection point between the inner door shell 7 and the connection profile 4 lies on the narrow sides 2 of the door, a circumferential connection point is obtained which, due to the spring-like design of the sheet metal edge and the pocket 8 in the connection profile 4, is easy to assemble and tight against the escape of foam is. The welded corners of the inner door shell 7 are tight and insensitive to impact. They are smooth on the surface by grinding.
