Fig. 12 einen Schnitt durch ein Ausführungsbeispiel ähnlich Fig. 10, bei welchem ein Längskanal aufgrund der Form des klammerartigen Verbindungselementes und einer Aussparung der Gehäuseteile gebildet worden ist. Fig. 12 is a section through an embodiment similar to Fig. 10, in which a longitudinal channel has been formed due to the shape of the bracket-like connecting element and a recess in the housing parts.
Das in Fig. 1 dargestellte Gehäuse besteht aus zwei Teilen 10, 11, die eine Aufnahme 12 für ein Gebläserad eines Venti lators und eine Aufnahme 13 für einen Filter oder für einen Heizungswärmetauscher oder einen Verdampfer einer Klimaanlage bilden. Die beiden Teile sind aus Partikelschaum aus thermo plastischem Kunststoff hergestellt, wie dies beispielsweise in der nicht vorveröffentlichten deutschen Patentanmeldung 197 47 645.7 offenbart ist. Die beiden Teile 10, 11 des Ge häuses werden an einer umlaufenden Trennfuge zusammengefügt. Um dabei eine möglichst feste und auch gleichzeitig weitge hend dichte Verbindung zu erhalten, sind die umlaufenden Rän der mit einer nutartigen Aussparung 14 versehen, die in der Zeichnung nur bei dem Teil 10 sichtbar ist. In diese nutarti gen Aussparungen greift ein schienenartiges Verbindungsele ment 15 ein, das die Form einer Leiste hat. Auf die Ausge staltung dieses Verbindungselementes 15 wird in Verbindung mit Fig. 2 bis 6 noch näher eingegangen. Das schienenartige Verbindungselement 15 erfüllt mehrere Funktionen. Das Verbin dungselement stellt einerseits eine kraftschlüssige Verbin dung zwischen den Teilen 10, 11 des Gehäuses her. Anderer seits erhöht es die Dichtheit zwischen den beiden Gehäusetei len 10, 11 in dem Bereich der Fuge während es darüber hinaus die Steifigkeit des gesamten Gehäuses erhöht. Das Verbindung selement 15 besteht aus einem massiven Werkstoff, d. h. nicht aus einem Schaumstoff. Es kann aus Kunststoff, Stahl, Alumi nium oder Verbundwerkstoffen bestehen. Das Verbindungselement kann auch in eines der Teile 10 oder 11 des Gehäuses bereits bei dessen Herstellung eingelegt werden, d. h. eingeschäumt werden. In diesem Fall benötigt nur das andere Teil eine um laufende Nut. In diesem Fall ist es auch zweckmäßig, wenn das Verbindungselement aus einem Kunststoff besteht, der mit dem Kunststoff des Partikelschaums des Teiles 10 oder 11 des Ge häuses in einfacher Weise recycelt werden kann.The housing shown in Fig. 1 consists of two parts 10 , 11 , which form a receptacle 12 for a fan of a venti lator and a receptacle 13 for a filter or for a heating heat exchanger or an evaporator of an air conditioning system. The two parts are made of particle foam made of thermoplastic, as is disclosed, for example, in the unpublished German patent application 197 47 645.7. The two parts 10 , 11 of the housing are joined together at a circumferential joint. In order to obtain a connection that is as firm as possible and at the same time largely tight, the peripheral edges are provided with a groove-like recess 14 , which is only visible in part 10 in the drawing. In these nutarti conditions recesses a rail-like element 15 element 15 , which has the shape of a bar. On the design of this connecting element 15 will be discussed in more detail in connection with FIGS. 2 to 6. The rail-like connecting element 15 fulfills several functions. The connec tion element on the one hand produces a non-positive connec tion between the parts 10 , 11 of the housing. On the other hand, it increases the tightness between the two housing parts len 10 , 11 in the region of the joint while it also increases the rigidity of the entire housing. The connection element 15 consists of a solid material, ie not of a foam. It can consist of plastic, steel, aluminum or composite materials. The connecting element can also be inserted into one of the parts 10 or 11 of the housing during its manufacture, ie it can be foamed. In this case, only the other part needs a running groove. In this case, it is also useful if the connecting element consists of a plastic that can be easily recycled with the plastic of the particle foam of part 10 or 11 of the housing.
Ein leistenförmiges Verbindungselement kann in einfacher Wei se durch Walzen oder Strangpressen hergestellt werden. Dar über hinaus ist es in einfacher Weise durch Biegen derart verformbar, daß es der Kontur der Fuge zwischen den beiden Teilen 10, 11 des Gehäuses ohne weiteres angepaßt werden kann.A strip-shaped connecting element can be produced in a simple manner by rolling or extrusion. In addition, it is deformable in a simple manner by bending such that it can be easily adapted to the contour of the joint between the two parts 10 , 11 of the housing.
In Fig. 2 bis 5 sind Beispiele für die Gestaltung von lei stenförmigen Verbindungselementen 15 dargestellt, wobei die Darstellung gegenüber der natürlichen Größe etwa um das 5- fache vergrößert ist. Im einfachsten Fall hat das Verbin dungselement 15 einen rechteckigen Querschnitt (Fig. 2), des sen Kanten angefast oder abgerundet sind. Die Breite des lei stenförmigen Verbindungselementes 15 ist breiter als die Breite der nutartigen Aussparung 14, so daß das Verbindungs element 15 unter plastischer Verformung der Seitenwände der nutartigen Aussparung 14 eingesetzt wird.In Fig. Examples 2 to 5 for the design of lei stenförmigen connecting members 15 are illustrated, the view being enlarged with respect to the natural size of about fold by 5X. In the simplest case, the connec tion element 15 has a rectangular cross section ( FIG. 2), the edges of which are chamfered or rounded. The width of the lei-shaped connecting element 15 is wider than the width of the groove-like recess 14 , so that the connecting element 15 is inserted with plastic deformation of the side walls of the groove-like recess 14 .
Aufgrund der plastischen Verformung ergibt sich eine kraft schlüssige Verbindung zwischen dem Verbindungselement 15 und den beiden Teilen 10, 11 des Gehäuses. Wenn die beiden Teile 10, 11 jeweils eine geschlossen umlaufende nutartige Ausspa rung 14 aufweisen, so ist es zweckmäßig, wenn die Tiefe der nutartigen Aussparung größer als die Höhe des Verbindungsele mentes ist, so daß die in der nutartigen Aussparung vorhande ne Luft in den Endbereichen komprimiert werden kann. Außerdem lassen sich Toleranzen leicht ausgleichen. Ferner ist es vor teilhaft, die eingeschlossene Luft an einer geeigneten Stelle abzuleiten, z. B. im Bereich einer Gebläsespirale.Due to the plastic deformation there is a positive connection between the connecting element 15 and the two parts 10 , 11 of the housing. If the two parts 10 , 11 each have a closed circumferential groove-like recess 14 , it is expedient if the depth of the groove-like recess is greater than the height of the connecting element, so that the air present in the groove-like recess in the end regions can be compressed. Tolerances can also be easily compensated. Furthermore, it is geous before deriving the trapped air at a suitable location, for. B. in the area of a fan coil.
Um zu der kraftschlüssigen Verbindung zwischen den Teilen 10 und 11 des Gehäuses und dem leistenartigen Verbindungselement eine gewisse formschlüssige Verbindung zusätzlich zu erhal ten, wird das Verbindungselement 15 im Bereich seiner Längs wände mit einer oder mehreren Profilierungen in Form von Rip pen und Vertiefungen versehen, wie dies in Fig. 3 und 4 dar gestellt ist. Diese Profilierungen verlaufen im wesentlichen in Längsrichtung des leistenförmigen Verbindungselementes, wobei sie nicht gradlinig verlaufen müssen, sondern bei spielsweise auch mäanderförmig verlaufen können. Eine derart profilierte Leiste 15' oder 15'' eignet sich insbesondere auch dafür, daß diese in eines der beiden Teile 10 oder 11 des Gehäuses eingeschäumt wird.In order to get a certain positive connection to the positive connection between the parts 10 and 11 of the housing and the strip-like connecting element in addition, the connecting element 15 is provided in the region of its longitudinal walls with one or more profiles in the form of ribs and depressions, such as this is shown in FIGS. 3 and 4. These profiles run essentially in the longitudinal direction of the strip-shaped connecting element, whereby they do not have to run in a straight line, but can also run in a meandering manner for example. A bar 15 'or 15 ''profiled in this way is also particularly suitable for being foamed into one of the two parts 10 or 11 of the housing.
Bei dem Ausführungsbeispiel nach Fig. 5 ist ein leistenförmi ges Verbindungselement 15''' vorgesehen, dessen in die nuten artigen Aussparungen 14 eindringenden Bereiche sich keilför mig zu dem Ende hin verjüngen. In dem mittleren Bereich ist das leistenförmige Verbindungselement 15''' auf beiden Seiten mit Längsrippen 16 versehen. Bei einer nicht dargestellten Ausführungsform ist nur auf einer Seite eine Längsrippe vor gesehen.In the embodiment according to FIG. 5, a strip-shaped connecting element 15 '''is provided, the areas penetrating into the groove-like recesses 14 tapering wedge-shaped towards the end. In the central area, the strip-shaped connecting element 15 '''is provided with longitudinal ribs 16 on both sides. In an embodiment, not shown, a longitudinal rib is seen only on one side.
Wie aus Fig. 6 zu ersehen ist, sind die keilförmigen Bereiche des Verbindungselementes 15' breiter als die nutartigen Aus sparungen 14 der Gehäuseteile 10 und 11. Sie dringen daher unter elastischer Verformung der Wandungen der Aussparung in diese Aussparungen ein. Wie weiter dargestellt ist, sind die nutartigen Aussparungen 14 tiefer als die Höhe der jeweils in sie eindringenden Abschnitte des Verbindungselementes 15''', so daß jeweils ein Raum belassen ist, in den beim Einschieben des Verbindungselementes 15''' in die nutartigen Aussparungen 14 die vorher darin vorhandene Luft verdrängt werden kann. As can be seen from Fig. 6, the wedge-shaped areas of the connecting element 15 'are wider than the groove-like savings 14 from the housing parts 10 and 11th They therefore penetrate into these recesses with elastic deformation of the walls of the recess. As is further shown, the groove-like recesses 14 are deeper than the height of the sections of the connecting element 15 '''penetrating into them, so that a space is left in each case in which when the connecting element 15 ''' is inserted into the groove-like recesses 14 the air previously present in it can be displaced.
Die Stege 16 begrenzen dabei jeweils die Eindringtiefe in die nutartigen Aussparungen 14.The webs 16 each limit the depth of penetration into the groove-like recesses 14 .
Wie ferner in Fig. 6 dargestellt ist, sind in dem Gehäuseteil
10 Aussparungen 17 vorgesehen, in die ein Werkzeug einführbar
ist, das dann an die Stege 16 des Verbindungselementes 15'
angreifen kann, so daß dieses von dem Gehäuseteil 10 lösbar
ist, ohne die Gehäuseteile 10, 11 zu beschädigen. Bei dieser
Ausführungsform kann das Verbindungselement 15''' auch in das
Teil 11 eingeschäumt werden.As is also shown in FIG. 6, recesses 17 are provided in the housing part 10 , into which a tool can be inserted, which is then attached to the webs 16 of the connecting element 15 '.
can attack so that it can be detached from the housing part 10 without damaging the housing parts 10 , 11 . In this embodiment, the connecting element 15 '''can also be foamed into the part 11 .
Wie Fig. 4 zeigt, können derartige Stege 16 auch an den ande ren Formen der Verbindungselemente 15' und 15 vorgesehen wer den.As shown in FIG. 4, webs 16 of this type can also be provided on the other forms of connecting elements 15 'and 15 who.
Fig. 2 bis 5 stellen nur Gestaltungsmöglichkeiten dar, wobei ohne weiteres Abwandlungen möglich sind. Beispielsweise ist es auch möglich, die Ausführungsbeispiele nach Fig. 2 bis 5 miteinander zu kombinieren, insbesondere in der Weise, daß eine Hälfte der Verbindungselemente 15, 15', 15'', 15''' eine andere Gestalt aufweist, d. h. die Gestalt eines der anderen Verbindungselemente. Beispielsweise ist es dadurch möglich, das Verbindungselement so zu profilieren, daß es in einem der Teile 10, 11 fester gehalten ist. Bei einer Demontage bleibt das Verbindungselement dann stets in dem gleichen Teil 10 oder 11 des Gehäuses. Fig. 2 to 5 represent only design possibilities, being possible without further modifications. For example, it is also possible to combine the exemplary embodiments according to FIGS. 2 to 5 with one another, in particular in such a way that one half of the connecting elements 15 , 15 ', 15 '', 15 ''' has a different shape, ie the shape of a of the other fasteners. For example, it is thereby possible to profile the connecting element in such a way that it is held more firmly in one of the parts 10 , 11 . When dismantling, the connecting element then always remains in the same part 10 or 11 of the housing.
In Fig. 7 und 8 ist eine weitere Ausführungsform von Verbin dungselementen 18, 19 dargestellt. Diese Verbindungselemente 18, 19 weisen jeweils Längsnuten 20, 21 auf, in die Längsrip pen der Gehäuseteile 10, 11 eingesteckt sind, wie dies in Fig. 7 strichpunktiert angedeutet ist. Die Längsnuten 20, 21 sind hinterschnitten. Die Längsrippen der Gehäuseteile 10, 11 besitzen eine schwalbenschwanzförmige Gestalt, und sind in der Breite etwas größer als die Längsnuten 20, 21. Die Ränder der die Längsnuten 20, 21 begrenzenden Stege sind nach außen abgewinkelt. Dadurch ist es möglich, beispielsweise in dem Teil 11 des Gehäuses eine Aussparung 22 vorzusehen, so daß ein Trennen der beiden Gehäuseteile 10, 11 möglich ist, indem mit einem Werkzeug an das Verbindungselement 18 oder 19 ange griffen wird, das ohnehin gut zugänglich ist, da es außen liegt.In Figs. 7 and 8 is another embodiment of Verbin-making elements 18 shown 19th These connecting elements 18 , 19 each have longitudinal grooves 20 , 21 , into which longitudinal ribs of the housing parts 10 , 11 are inserted, as is indicated by dash-dotted lines in FIG. 7. The longitudinal grooves 20 , 21 are undercut. The longitudinal ribs of the housing parts 10 , 11 have a dovetail shape and are somewhat larger in width than the longitudinal grooves 20 , 21 . The edges of the webs delimiting the longitudinal grooves 20 , 21 are angled outwards. This makes it possible, for example, to provide a recess 22 in the part 11 of the housing, so that a separation of the two housing parts 10 , 11 is possible by gripping the connecting element 18 or 19 with a tool, which is easily accessible anyway, because it's on the outside.
Das Verbindungselement 18 weist zwischen den beiden Längsnu ten eine Hohlkammer 23 auf, so daß es mit einer erheblichen Formsteifigkeit gestaltet werden kann. Wenn diese Formstei figkeit nicht erforderlich ist, so können die Längsnuten 20, 21 unmittelbar aneinander anschließen, d. h. es kann nur ein Quersteg zwischen den beiden Längsnuten 20, 21 vorhanden sein.The connecting element 18 has a hollow chamber 23 between the two Längennu th, so that it can be designed with a considerable rigidity. If this stiffness is not required, the longitudinal grooves 20 , 21 can directly adjoin one another, ie there can be only one crosspiece between the two longitudinal grooves 20 , 21 .
Bei dem Ausführungsbeispiel nach Fig. 8 besitzt das Verbin dungselement 19 einen mittleren Längssteg 24, von welchem zur Aussteifung Querstege abragen können. Während das Verbin dungselement 18 im wesentlichen nur durch Extrudieren her stellbar ist, läßt sich das Längsprofil 19 auch auf andere Weise herstellen. Wie eingangs schon erwähnt worden ist, kann an den Verbindungselementen 18, 19 die Befestigung von Zu satzbauteilen erfolgen. Darüber hinaus ist es möglich, die Hohlkammer 23 des Verbindungselementes 18 beispielsweise zum Verlegen elektrischer Leitungen oder zum Führen von Betäti gungselementen wie Bowdenzügen o. dgl. auszunutzen.In the embodiment of FIG. 8, the connec tion element 19 has a central longitudinal web 24 , from which transverse webs can protrude for stiffening. While the connec tion element 18 can be made essentially only by extrusion, the longitudinal profile 19 can also be produced in other ways. As has already been mentioned at the beginning, the fastening of structural components can take place on the connecting elements 18 , 19 . In addition, it is possible to use the hollow chamber 23 of the connecting element 18, for example for laying electrical lines or for guiding actuating elements such as Bowden cables or the like.
In Fig. 9 bis 12 ist eine weitere Ausführungsform von schie nenartigen Verbindungselementen 25, 25' dargestellt, die ebenfalls in Längsrichtung von Trennfugen zwischen Teilen 10 und 11 eines Gehäuses verlaufen und die die beiden Teile im wesentlichen kraftschlüssig miteinander verbinden. Diese schienenartigen Verbindungselemente 25, 25' haben eine im we sentlichen U-förmige Gestalt, mit in Längsrichtung der Fuge verlaufenden Schenkeln. Die Verbindungselemente halten die beiden Teile 10, 11 des Gehäuses klammerartig zusammen. Die Teile 10, 11 des Gehäuses sind mit parallel zu der Fuge ver laufenden Flanschen versehen, die die Schenkel der Verbin dungselemente 25, 25' umgreifen. Es ist jedoch auch möglich, auf derartige Flansche zu verzichten, und die Schenkel in nutartige Aussparungen der Teile 10, 11 einzustecken, die parallel zu der Trennfuge verlaufen. Die außen an dem Gehäuse angebrachten Verbindungselemente 25, 25' können dazu ausge nutzt werden, einen in Längsrichtung der Trennfuge verlaufen den Kanal zu bilden. Wie Fig. 11 zeigt, können hierzu beide Teile 10, 11 des Gehäuses entsprechend ausgespart sein. Na türlich genügt es, auch nur ein Teil 10 oder 11 auszusparen. Bei einer abgewandelten Form wird vorgesehen, daß das Verbin dungselement 25' so geformt ist, daß es alleine den Längska nal bildet. Wie Fig. 12 zeigt, können beide Maßnahmen mitein ander kombiniert werden, d. h. ein Teil des Längskanals kann von dem Verbindungselement 25' und ein Teil des Längskanals durch eine Aussparung in einem oder beiden Teilen 10, 11 des Gehäuses gebildet werden.In Fig. 9 to 12 a further embodiment of rail-like connecting elements 25 , 25 'is shown, which also extend in the longitudinal direction of joints between parts 10 and 11 of a housing and which connect the two parts essentially non-positively. These rail-like connecting elements 25 , 25 'have a substantially U-shaped shape, with legs extending in the longitudinal direction of the joint. The connecting elements hold the two parts 10 , 11 of the housing together like a clamp. The parts 10 , 11 of the housing are provided with flanges running parallel to the joint and encompassing the limbs of the connecting elements 25 , 25 '. However, it is also possible to dispense with such flanges and to insert the legs into groove-like recesses in the parts 10 , 11 which run parallel to the parting line. The connecting elements 25 , 25 'attached to the outside of the housing can be used to form a channel running in the longitudinal direction of the parting line. As Fig. 11 shows, this may be omitted in accordance with both parts 10, 11 of the housing. Of course, it is enough to leave out only part 10 or 11 . In a modified form it is provided that the connec tion element 25 'is shaped such that it alone forms the Längska channel. As Fig. 12 shows, both measures can mitein other combined, ie, a part of the longitudinal channel of the housing can be formed from the connecting element 25 'and a portion of the longitudinal channel by a recess in one or both parts 10, 11.
Abhängig von der Form und der Dimensionierung, insbesondere der Verbindungselemente 18, 19 und 25, 25' kann eine erhebli che Aussteifung erhalten werden. Dabei ist es möglich, die Verbindungselemente so anzuordnen, daß sie sich im Bereich einer Armaturentafel über die gesamte Breite des Fahrzeuges erstrecken und die beiden A-Säulen verbinden. In diesem Falle ist es möglich, an diesen Elementen die gesamte Armaturenta fel zu befestigen. In diesem Fall können beispielsweise die von den Profilen 18, 25, 25' gebildeten Kanäle als Luftver teilkanäle im Bereich der Armaturentafel ausgenutzt werden.Depending on the shape and the dimensions, in particular the connecting elements 18 , 19 and 25 , 25 ', a considerable stiffening can be obtained. It is possible to arrange the connecting elements so that they extend in the area of a dashboard across the entire width of the vehicle and connect the two A-pillars. In this case, it is possible to attach the entire dashboard to these elements. In this case, for example, the channels formed by the profiles 18 , 25 , 25 'can be used as air channels in the area of the dashboard.
