Abstract

The cover section is for bridging the distance between the two shells of the chest wall. It has locking elements for securing the angled shell edges and the space between the two outer shells of the chest wall, bridged by the cover section, is filled with foam. It is regarded as the characterising feature of the invention that the locking element (12) has a flexible rest (124) for the shell edge (21). A head part (125), extending to points (1251, 1252), is formed on at the free end of the flexible rest (124), approximately at right angles to the axis of the rest (124). In the locking state, this head part (125) on the one hand enters into effective connection with a longitudinally extending engaging groove (16), shaped in assigned bottom regions of the cover section (1). On the other hand, the head part (125) bears in a sealing manner against the outer wall (211) of the angled shell edge (21).

Description

Die Meuerung betrifft ein Aodeckprofil für Kunltruhen zur Überbrükkung des Abstandes der beiden Schelen der Trunenwand, wobei das Audeckprotil wastelemante zur Malterung der abgewinkelten Scnalenrander aufweist und wobei der von dem Abdeckprofil überbrückte Kaum zwischen den Schalen der Truhenwend ausgeschaumt ist.The control relates to an Aodeckprofil for artificial chests to bridge the distance between the two trenches of the Trune wall, the Audeckprotil having wastelemante for painting the angled scale edges and the bar bridged by the cover profile between the trays of the chest truss is foamed.

Kühltruhen bestehen in der Regel aus zwei Blechrahman, die is Abstand veneinander angeordnet sind. Der Zwischenraum zwischen diesen beiden Blacnrahmen wird mit einer isolierenden Schaummasse gefullt. Proulematisch hierbei ist die Abdeckung des Zwischenraus der Blechranmen vor und wahreng der Ausschaumung. Zur uberbruckung des Zwischenraumes dient nacn dem Stand der Technik ein Abdecxprofil aus Kunststoff, welches einen Funktionssteg aufweist, der wenigstens in Teilbereichen flexibel genalten ist. Der abgewinkelte Rand der Blechschale ubergreift einen abgewinkelten Rand des Funktionssteges und dieser wird infolge der teilweisen Flexibilltst von Wanduerelctren auf die Innenwand des Abdeckprofils zu verschoben. Von der Innenwand des Abdeckprofils stent nach dem unbekannten Stand der Techmik ein nockenartiger Ansatz auf, der in der Höhe der Dicke des asgewinkelten Wandbereiches as Abdeckprofil entspricht. Wenn der abgewinkelte Kand der Blechschale das freie Ende des von der Innenwandung des Abdeckprofils aufragenden Aostandnockens berührt, liegt gleichzeitig das freie Ende des abgweinkelten Schalenrandes auf dem abgewinkelten frelen Ende des Funktionssteges auf. Der Einschubvorgang der Schale in das Abdeckprofil ist damit beendet.Freezers usually consist of two sheet metal frames that are spaced apart. The space between these two frame frames is filled with an insulating foam compound. Proulematic here is the covering of the space between the sheet metal frames before and during the expansion. In order to bridge the gap, the prior art uses a plastic cover sheet that has a functional web that is flexible, at least in some areas. The angled edge of the sheet metal shell overlaps an angled edge of the functional web and this is moved towards the inner wall of the cover profile due to the partial flexibility of wall heating. From the inner wall of the cover profile stent according to the unknown state of the art a cam-like approach, which corresponds in height to the thickness of the angled wall area as the cover profile. When the angled edge of the sheet metal shell touches the free end of the aostand cam protruding from the inner wall of the cover profile, the free end of the angled edge of the shell rests on the angled free end of the functional web. The process of inserting the shell into the cover profile is now complete.

Zur Bildung des Moniraumes zwischen zwel Schalen ist dieser Einschubrorgung am anderen Ende des Abduckprofils in der guschilderten oder einer annlichen Weise zu wiederholen. Uamit ist ein gaschlossener Hohiraum geschaffen, der nummehr umlaufend mit dem isolierenden Schaumstoffwaterial gefullt werden kann. Hierbei hat sich als nachteilig erwiesen, daß die Verrasterung der abgewinkelten Schalenrander in aen dafur vorgesenenen Außenbereichen des Abdeckprofils nicht ausreichend ist.To form the moni space between two shells, this insertion procedure must be repeated at the other end of the impression profile in the manner described or in a similar manner. This creates a gas-enclosed cavity, which can be filled all the way with the insulating foam material. It has proven to be disadvantageous here that the locking of the angled shell edges in aen provided outside areas of the cover profile is not sufficient.

Es hat sich insbesondere als nachteilig herausgestellt, daß infolge des Schaumdrucks im Innenraum zwischen den beiden Schalen im Verbindungsbereich zwischen den Schalenrandern und dem Abdeckprofil infolge mangeinder mechanischer Verbindung Schaumantelle zwischen dem Abdeckprofil und den abgewinkelten Schalenrandern ausgetreten sind, die durch spatere Macharpeit in arueitsaufwendiger und damit kostspieliger Weise entfernt werden mußten.It has been found to be particularly disadvantageous that, due to the foam pressure in the interior between the two shells in the connection area between the shell edges and the cover profile due to inadequate mechanical connection, foam layers between the cover profile and the angled shell edges have escaped, which due to later macharpeit are labor-intensive and therefore more expensive Way had to be removed.

Mier setzt die Meuerung ein, die as sich zur Aufgabe gestellt hat, ein Abdeckprofil für Kunltrunen zur überbrückung des Abstandes der beiden Schalen der Truhenwand zu schaffen, bei dem die mechanische Varbindung zwischen Abdeckprofil und abgewinkelten Schalenrandern optimal ist und bei dem leichte Toleranzen in den Abuessungen der abgewinkelten Schalenrander ausgaglichen warden können. Meuerungsgewas wird dazu vorgeschlagen, daß das Rastelesent eine flexible Auflage fur den Schalenrand aufweist, an deren freien Ende annahernd rechtwinkelig zur Achse der Auflage ein in Spitzen verlaufendes Kopfteil angeformt ist, weichas im Verrasterungszussand einerseits mit einer in zugeordneten Bodenbereichen des Abdeckprofils ausgeformien, langsverlaufenaen Einrastrille in Verbindung tritt und andererseits an der AuBenwand des abgewinkelten Schalenrandes dichtend anliegt.Mier uses the control system, which has set itself the task of creating a cover profile for artificial runes to bridge the distance between the two shells of the chest wall, in which the mechanical bond between the cover profile and angled shell edges is optimal and with the slight tolerances in the dimensions the angled edge of the bowl can be Meuerungsgewas is proposed that the locking element has a flexible support for the shell edge, at the free end of which a tip-shaped head part is formed approximately at right angles to the axis of the support, which, on the one hand, is formed in the interlocking condition with a slow-moving engagement groove formed in the assigned base areas of the cover profile Connection occurs and, on the other hand, lies sealingly against the outer wall of the angled edge of the shell.

Das Abdeckprofil besitzt also für die Aufnahae der abgewinkelten Schaienrander einen Rastbereich, weicher einerseits von der rechtwinkelig abgewinkelten Außenwand des Abdeckprofils und andererseits von einem Raststeg begrenzt ist, welcher gelenkig bewegbar ist und an seinem freien Ende eine flexible Auflage für den Schalenrand aufweist. Am freien Ende dieser flexiblen Auflage ist das Kopfteil angeformt, weiches annanernd rechwinkelig zur Achse der Auflage verlauft. Vieses Kopftell lauft nach oben und unten in Spitzen aus, wobei die untere Spitze mit einer im Boden des Abdeckprofils ausgeformten langsverlaufenden Einrastrille im Verrasterungszustand kommunizaiert. In diesem Zustand liegt die gegenüberliegende Spitze des Kopfteils an der Außenwand des abgewinkelten Schalenrandes dichtend an, Vorteilhaft sind in den zugeordneten Bodenbereichen des Abdeckprorils menrere langsverlaufende Einrastrillen hintereinander ausgeformt. Auf diese Weise konnen Toleranzen in der Abwinkelung des Schalenrandes ohne weiteres ausgeglichen werden, so daß bei langerer Abwinkelung des Schalenrandes eine weiter von der außeren Abwinkelung des Abdeckprofils entfernt liegende Einrastrille gewählt wird und umgekehrt.The cover profile therefore has a latching area for receiving the angled shell edges, which is delimited on the one hand by the right-angled outer wall of the cover profile and on the other hand by a latching web which is articulated and has a flexible support for the shell edge at its free end. At the free end of this flexible support, the head part is molded on, softly running perpendicular to the axis of the support. Vieses head plate runs up and down in tips, the lower tip communicates with a slow-running snap-in groove formed in the bottom of the cover profile in the locked state. In this state, the opposite tip of the head part lies sealingly against the outer wall of the angled shell edge, Advantageously, menrere slow-running snap-in grooves are formed one behind the other in the assigned floor areas of the covering profile. In this way, tolerances in the angle of the shell edge can be easily compensated for, so that if the edge of the shell is bent for a longer time, a snap-in groove which is further away from the outer angle of the cover profile is selected, and vice versa.

Es erscheint ferner zweckmaßig. daß im Anschluß an die Einrastrillen zum adgewinkelten Kand des Abdeckprofils hin verlagert wenigstens eine langsverlaufende Hippe in den Bodenbereichen des Abdeckprofils angeformt ist, weiche in der Mohe den Abessungen des in die Einrastrille eingesetzten Kopfteils der flexiblen Auflage entspricht. Die kippen sind vorteilhaft spitz gehalten und liegen im verrasteten Zustand der abgewinkelten Schalenrander wie die Spitze das Kopfteils an der Außenwand des Scnalenrandas dichtend an.It also seems appropriate. that at least one slow-running hipper is formed in the bottom regions of the cover profile, which corresponds in height to the dimensions of the head part inserted into the engagement groove of the flexible support. The tips are advantageously kept pointed and are in the locked state of the angled shell edges like the tip of the head part sealingly against the outer wall of the scala edge.

Auf die geschilderte weise laßt sich eine optimale Abdichtung des Innenraumes zwischen den beiden Außenschaien erzieien, so daß sich bei der Ausschaumung dieses Innenraumes der nachteilige Austritt des Isolierschaumes wegne undichter Stellen zwischen den beiden Schalenhalften nicht mehr ergibt. in der Zeichnung ist ein Ausfuhrungsbeispiel des neuerungsgemaßen Abdeckprofils schematisch dargestellt; es zeigt:

  • Fig. 1 den Einrastbereich des Abdeckprofils und des zugeordneten abgewinkelten Schalenrandes im Schnitt.
  • Fig. 2 den geschnittenen Teilbereich einer Kuhltruhenwand unter Verwendung des neuerungsgemaßen Abdeckprofils.
In the manner described, an optimal sealing of the interior between the two outer shells can be achieved, so that when this interior is filled with foam, the disadvantageous leakage of the insulating foam away between the two halves of the shell no longer results. in the drawing, an exemplary embodiment of the new covering profile is shown schematically; it shows:
  • Fig. 1 shows the locking area of the cover profile and the associated angled shell edge in section.
  • Fig. 2 shows the cut portion of a freezer wall using the new cover profile.

In Fig. 1 ist das Ende des Abdeckprofils 1 mit des abgewinkeltenkslten kandereich 11 zu senen. Das Rastelement 12 besteht aus einem sich konisch nach oben verjungenden Rastfuß 121, welcher in seiner hochsten Erhebung 122 den Bereich seines geringsten Querschnitts aufweist. Mach diesem Bereich der höchsten Erhedung 122 verläuft das Rastelement 12 mit seinem Fußteil 123 annahernd in Richtung zum abgewinkelten Schalenrand 11 auf die Innenwandbereiche das Abddeckprofils 1 zu. Am freien Ende des Fußteils 123 ist eine fiächige, flexible Aufiage 124 engeformt, welche an ihrem freien Ende annähernd rechtwinkelig zu Ihrer Achse das in Spitzen verlaufende Kopfteil 125 tragt. Die flexible Auflage 124 ist an das freie Ende des Fußteils 123 derart angeformt, daß dort durch einen Überstehenden Bereich 1231 des Fußeils 123 in Verbindung mit Innenwandbereichen der flexiblen Aufiage 124 eine Aufnahwenut 126 für das freie Ende 22 des Scnalenrandes 21 im Kastszustand geschaffen wird.In Fig. 1, the end of the cover profile 1 with the angled corner area 11 can be seen. The locking element 12 consists of a conically tapering upward locking foot 121, which in its highest elevation 122 has the area of its smallest cross-section. Because of this area of the highest elevation 122, the latching element 12 runs with its foot part 123 approximately in the direction of the angled shell edge 11 towards the inner wall areas of the covering profile 1. At the free end of the foot part 123, a flat, flexible overlay 124 is narrowly formed, which carries the tip part 125 running at points at its free end approximately at right angles to your axis. The flexible support 124 is molded onto the free end of the foot part 123 in such a way that a receiving groove 126 for the free end 22 of the scanning edge 21 in the box state is created there by a protruding area 1231 of the foot part 123 in connection with inner wall areas of the flexible support 124.

Durch den konisch nach oben verlaufenden Rastfuß 121 und den abgewinkeiten Rand 11 das Abdeckproils 1 wird damit ein U-förmiger Aufnahmeraum 13 geschaffen. in den der abgewinkelte Schalenrand 21 der Schaie 2 einbringbar und dort verrastbar ist. Das Einbringen des Schalenrandes 21 in den U-formigen Aufnahmeraum 13 erfolgt in Pfeilrichtung, wobei das freie Ende 22 des abgewinkelten Schalenrandes 21 mit den Außenwanbdereichen des Fußteiles 123 in Beruhrung tritt, in diesem Augenblick beruhrt auch die zugeordnete Außenwand 23 der Schale 2 den zugeordneten Innenwandbereich 14 des abgewinkelten Teils 11 des Abdeckprofils 1. beils weiteren Verschieben der Schile 2 in Richtung auf den boden des ü-formigen Aufnahmeraumes 13 wird des Fußteil 123 in Richtung auf den konisch nach oben verlaufenden Rastfuß 121 verschoben. Hierbei tritt der Sereich 122 in seiner Scharnierfunktion vorteilhaft in Erscheinung. Bei dieser Verschiebung Wandert das Kopfteil 125 in kichtung auf die zugeordnete Einrastrille 15, 10, 17 und rastet in eine dieser Rillen in dem Augenblick ein, in dem das freie Ende 22 des abgewinkelten Schalenrandes 21 in die Hut 126 einschnappt. in diesem Endzustand liegt die Spitze 1251 des Kopfteils 125 in einer der zugeordneten Einrastrillen 15, 16, 17 und die Spitze 1252 des Kopfteils 125 liegt am zugeordnaten Außenwandbereich 211 des abgewinkelten Schalenrandes 21 dichtend an. Ferner liegen an diesem Außenbereich 211 des abgewinkelten Schalenrandes 21 die Spitzen 18, 19 ebenfalls dichtend an. Die Abdichtung gegenüber dem Innenraum zwischen zwei derart verrasteten Schalen 1,2 erfolgt aiso in der gezeigten Darstellung an vier einzelnen Punkten:

  • Erstmals im bereich der Aufnahmenut 126 durch Anliegen des freien Endes 22 des aogewinkelten Schalenrandes 21 an den dortigen Wandbereichen am Boden der Aufnahmenut 126; danach durch Eingriff der Spitzu 1251 des Kopfteils 12b in eine der zugeordneten Einrastrillen 15, 1u, 17 und anliegende Spitze 1252 des Kopfteils 125 an der Aussenwand 211 des abgewinkelten Schalenrandes 21; zum dritten durch Anliegen der Dichtspitzen 1d, 19 an den zugeordneten Außenwandbereichen 211 des abgewinkelten Schalenrandes 21; schließlich durch Andruck der Außenwand 23 der Scnaie 2 an die Innenwand 14 des Abdeckprofils 1. Der entsprechende Verbindungsdruck wird durhc den Rastdruck des Fußteils 123 erzeugt, der beim Einschieben des abgewinkelten Schalenrandes 21 in den U-förmigen Aufnahmeraum 13 nach hinten zum konischen kastfuß 121 hin verdrückt wird und nach Einrasten das treien Endes 22 des abgewinkiten Schalenrandes 21 in die Aufnamenut 126 aufgrund der dem Kunststoff innewohnenden Elastizität den Anpressdruck der Außenwand 23 der Schale 2 an die innenwand 14 des Abdeckprofils 1 bewirkt.
A U-shaped receiving space 13 is thus created by the conical upward locking foot 121 and the angled edge 11 of the covering profile 1. into which the angled edge of the shell 21 of the shades 2 can be inserted and locked there. The shell edge 21 is introduced into the U-shaped receiving space 13 in the direction of the arrow, the free end 22 of the angled shell edge 21 coming into contact with the outer wall areas of the foot part 123, at this moment the associated outer wall 23 of the shell 2 also touches the assigned inner wall area 14 of the angled part 11 of the cover profile 1. as the plates 2 are moved further in the direction of the bottom of the U-shaped receiving space 13, the foot part 123 is moved in the direction of the conically upwardly extending latching foot 121. Here, the area 122 advantageously appears in its hinge function. During this displacement, the head part 125 moves towards the associated snap-in groove 15, 10, 17 and engages in one of these grooves at the moment when the free end 22 of the angled shell edge 21 snaps into the hat 126. in this final state, the tip 1251 of the head part 125 lies in one of the associated snap-in grooves 15, 16, 17 and the tip 1252 of the head part 125 lies sealingly on the associated outer wall area 211 of the angled shell edge 21. Furthermore, the tips 18, 19 also lie sealingly on this outer region 211 of the angled shell edge 21. The seal with respect to the interior between two shells 1, 2 locked in this way takes place aiso in the illustration shown at four individual points:
  • For the first time in the area of the receiving groove 126 by contacting the free end 22 of the angled shell edge 21 with the wall areas there at the bottom of the receiving groove 126; thereafter by engagement of the tip 1251 of the head part 12b in one of the associated snap-in grooves 15, 1u, 17 and the tip 1252 of the head part 125 resting against the outer wall 211 of the angled shell edge 21; thirdly, by the sealing tips 1d, 19 resting on the assigned outer wall regions 211 of the angled shell edge 21; finally by pressing the outer wall 23 of the scnaie 2 against the inner wall 14 of the cover profile 1. The corresponding connection pressure is generated by the latching pressure of the foot part 123 which, when the angled shell edge 21 is inserted into the U-shaped receiving space 13, towards the rear towards the conical box base 121 is pressed and, after latching in, the free end 22 of the angled shell edge 21 into the receiving groove 126, due to the elasticity inherent in the plastic, causes the contact pressure of the outer wall 23 of the shell 2 against the inner wall 14 of the cover profile 1.

Der in Fig. 2 dargestellte Teilbereich einer Kühltruhenwand unter Verwendung des neuerungsgemaßen Abdeckprofils 1 im Schnitt zeigt die Rastverbindung zwischen dem abgewinkelten Schalenrand 21 einerseits und den inneren Wandbereichen des Abeckprofils 1 in der bereits geschliderten Weise. In der Darstellung ist deutlich zu sehen, wie das freie Ende 22 des abgewinkelten Schalenrandes 21 am Grund der Aufnanmenut 126 anliegt. Aufgrund der in der Zeichnung gewanlten Länge das abgewinkelten Schalenrandes 21 ist das Kopfteil 125 in eine Position gebracht. in der die Spitze 1251 in der Rille 16 eingreift und die Spiltze 1252 des Kopfteils 125 an dem entsprechend zugeordneten Außenwandbereich des Schalenrandes 21 anliegt. Es ist in der Darstellung deutlich zu senen, daß die Dichtspitzen 18, 19 in gleicher Höhe liegen wie die Spitze 1252, so daß sich auf diese Weise drei hintereinduder angeordnete Dicntspitzen in Form einer Laby- rinthdichtung gegen den Austritt des lsollerschauwes gebildet haben. Solostverstandlich liegt es im Rahwen der Erfindung, die Dichtspit- zen 18, 19 belleblg zu verarehren. sowie an die flexible Auflage 124 im Bedartsfall nintereinander geschaltete Kapfteile anzuordnen, die dann mit wehreren Spitzen nach oben und unten ausgestattet und auf diese Weise die Abdichtungsmoglichkelten verwehren konnen.The section of a freezer wall shown in FIG. 2 using the cover profile 1 according to the innovation shows in section the latching connection between the angled shell edge 21 on the one hand and the inner wall regions of the cover profile 1 in the manner already outlined. The illustration clearly shows how the free end 22 of the angled shell edge 21 lies against the base of the receiving groove 126. Due to the length of the angled shell edge 21 chosen in the drawing, the head part 125 is brought into a position. in which the tip 1251 engages in the groove 16 and the tip 1252 of the head part 125 bears against the correspondingly assigned outer wall region of the shell edge 21. It is in the To see clearly that the sealing tips 18, 19 are at the same height as the tip 1252, so that in this way three rear-facing sealing tips in the form of a labyrinth seal have formed against the outlet of the oil shoulder. From a solo standpoint it is within the scope of the invention to adore the sealing tips 18, 19 belleblg. and, if necessary, to arrange cap parts connected to one another on the flexible support 124, which are then equipped with stronger tips upwards and downwards and in this way can prevent the sealing possibilities.

Das Audeckprofil 1 ist in der gezeigten Darstellung an sainem anderen freien Ende lediglich mit der Abwinkelung 11' versenen. Die Schale 2' ist lediglich hinter die Abwinkelung 11' eingebracht und wird durch mechanische, in der Zelchnung nicht gezeigte Eleuente in dieser Stillung gehalten.The outer cover profile 1 is only provided with the bend 11 'in the illustration shown at its other free end. The shell 2 'is only inserted behind the bend 11' and is held in this breastfeeding by mechanical elements, not shown in the drawing.

Der dadurch geschaffene Aufnahmeraum zwischen den beiden Schalen 2, 2' wird dann mit einem Scnauwstoff 3 dusgefullt. wobei das Verfahren der Ausfüllung zum Stand der Technik zahlt. Der Schaumstoff 3 drückt den abgewinkelten Schalenrand 21 der Schale 2 in seinen Sitz, wobei das Kopfteil 125 durch die Einrastung der Spitze 1251 in die Einrastrille 16 bei zunehwendem Andruck durch den Schaum nicht wehr entrastet werden kann. Damit ist der optimale Dichtabschluß zwischen dem Abdeckprofil 1 und der Schale 2 geschaffen.The receiving space created thereby between the two shells 2, 2 'is then filled with a plastic 3. the method of completion pays to the state of the art.
