Die DE-U-90 11 896 beschreibt Lagerkörper für eine Wickelwelle mit als Drehsicherung ausgebildeten Lagerzapfen.DE-U-90 11 896 describes bearing bodies for a winding shaft with bearing pins designed as anti-rotation devices.

Der Erfindung liegt die Aufgabe zugrunde, ein System dieser Gattung durch einfachen Aufbau und dennoch sicherer Positionierung in der Einbau- bzw. Montagelage trotz einfacher Montage und Demontage und geringem Raumbedarf zu verbessern und auch ästhetischen Gesichtpunkten Rechnung zu tragen, um auch den nachträglichen Anbau an Fensterflügeln, Türflügeln oder dergleichen Bauteilen so zu ermöglichen, daß das äußere Design der Gesamtanordnung nicht beeinträchtigt wird, und die Handhabung ohne wesentliche Verminderung der lichten Höhe der Fenster- oder Türscheibe möglich ist.The invention has for its object a system of these Genre through simple construction and nevertheless safe positioning in the installation or assembly position despite simple To improve assembly and disassembly and small space requirements and also to take aesthetic aspects into account in order to also retrofitting on window sashes, door sashes or the like components so that the outer Design of the overall arrangement is not affected, and the Handling without significantly reducing the clear height of the Window or door pane is possible.

Die Erfindung ist im Anspruch 1 gekennzeichnet und besonders bevorzugte Ausbildungen sind in den Ansprüchen 5 und 8 beansprucht. Weitere Ausbildungen der Erfindung sind in anderen Unteransprüchen beansprucht und werden anhand der Zeichnung durch die nachfolgende Beschreibung noch beschrieben.The invention is characterized in claim 1 and is special preferred designs are claimed in claims 5 and 8. Further embodiments of the invention are in others Subclaims are claimed and are based on the drawing described by the following description.

Bei dem erfindungsgemäßen System wird eine Einheit bestehend aus dem Gehäuse, dem Aufwickelorgan - sowie dem darauf aufzuwickelnden Wickelgut - und Lagerkörpern an beiden Stirnseiten des Gehäuses gebildet. Bei der Erfindung rastet ein im Querschnitt im wesentlichen T-förmiger Vorsprung, der vom Gehäuse absteht, als Sperrmittel in mindestens eine Aussparung an mindestens einem Schenkel am Halteorgan ein. Die Rastwirkung wird begünstigt durch eine federelastische Ausbildung des Halteorgans. Die obengenannte Einheit kann so in den vom Halteorgan gebildeten Raum eingeschoben oder insbesondere nach Einhaken an einem Ende eingeschwenkt oder eingesteckt werden, daß der Vorsprung am Gehäuse oder ggf. auch am Lagerkörper in den Bereich der Aussparung am Halteorganschenkel gelangt, worauf die Spreizwikrung desselben aufgehoben wird und der Vorsprung als Sperrmittel in die Aussparung einrastet.In the system according to the invention there is one unit from the housing, the winding member - and the one to be wound onto it Wrapped goods and bearings on both faces of the housing formed. In the invention, one snaps in cross section essentially T-shaped projection from the housing protrudes as a blocking means in at least one recess at least one leg on the holding member. The locking effect is favored by a resilient design of the holding member. The above-mentioned unit can thus in the of the holding member formed space inserted or especially after hooking be swung in or plugged in at one end that the protrusion on the housing or possibly also on the bearing body in the Area of the recess on the holding organ leg, whereupon the spreading movement of the same is canceled and the projection snaps into the recess as a locking means.

Das Ausmaß des federelastischen Aufspreizens wird dann gering gehalten, wenn sich Aussparungen im Bereich der freien Schenkelenden des Halteorgans befinden.The extent of the elastic expansion is then low held when there are recesses in the free area Leg ends of the holding member are.

Der Vorsprung steht von einer Außenfläche des Gehäuses bzw. Lagerkörpers ab; auch Ecken des Lagerkörpers können als solcher Vorsprung verwendet werden.The projection protrudes from an outer surface of the housing or Bearing body from; corners of the bearing body can as such Projection can be used.

Es empfiehlt sich, wenn ein freies Schenkelende des Halteorgans als Schwenklager für die obengenannte Baueinheit dient, während der andere davon abstehende Schenkel den Vorsprung mindestens teilweise an einer vom Schwenklager angewandten Seite übergreift und dort die Rasteinrichtung aufweist, die zwischen dem betreffenden Schenkel und dem Gehäuse bzw. Lagerkörper wirksam ist. Dabei kann es sich zur Einsparung von Material empfehlen, das Gehäuse nur an denjenigen Seiten des Aufwickelorgans und der Lagerkörper anzuordnen, die nicht von Schenkeln des Halteorgans abgedeckt sind.It is recommended if there is a free leg end of the holding member serves as a pivot bearing for the above-mentioned structural unit, while the other protruding leg the projection at least partially on one used by the swivel bearing Reaches over and there has the locking device that between the relevant leg and the housing or bearing body is effective. It can save Recommend material, the housing only on those sides of the To arrange the winding member and the bearing body, which are not of Legs of the holding member are covered.

Die Rastverbindung stellt eine federelastische Verankerung der wannenartigen Baueinheit in der Einbaulage dar. Durch Aufwenden eines gewissen Druckes wird dafür gesorgt, daß die Baueinheit in der Einbaulage in die Raststellung einschnappt. Durch Aufwenden eines gewissen Drucks kann die Raststellung auch wieder verlassen werden, um die Baueinheit um das Schwenklager zurückzuschwenken und Zutritt zum Aufwickelorgan und Wickelgut im Inneren der Baueinheit zu erlangen. The snap connection provides a spring-elastic anchorage of the tub-like unit in the installation position. By spending a certain pressure ensures that the The unit snaps into the locked position in the installed position. By applying a certain pressure, the locking position also be left again to the unit around that Swivel the swivel bearing back and access to the rewinder and to obtain winding material inside the unit.

Der Vorsprung ist insbesondere als von der Außenseite des Gehäuses abragender Befestigungssteg ausgebildet. Dabei greifen Aussparungen an Schenkelenden des Halteorgans an den freien Schenkelenden des Querbalkens des T-förmigen Befestigungsstegs derart an, daß auch hier eine Rastverbindung durch vorübergehendes Auseinanderspreizen der freien Schenkelenden des T-förmigen Befestigungsstegs in dafür vorgesehene Ausnehmungen im Halteorgan zustande kommt. Der Vorteil dieser Ausbildung besteht darin, daß auch im Querschnitt kreisförmige Gehäuse anwendbar sind, die insbesondere aus zwei halbschalenförmigen Mantelteilen zusammengesetzt sind. Beide Mantelteile werden durch die Lagerkörper an den Stirnenden des Gehäuses zusammengehalten.The protrusion is particularly as from the outside of the housing protruding fastening web is formed. Grab it Recesses on the leg ends of the holding member on the free Leg ends of the crossbar of the T-shaped fastening web in such a way that here also a snap-in connection by temporary Spreading apart the free leg ends of the T-shaped Fastening web in recesses provided for this comes about in the holding organ. The advantage of this training is that even in cross-section circular housing are applicable, in particular from two half-shell-shaped Sheath parts are composed. Both coat parts will held together by the bearing body at the front ends of the housing.

Hierzu empfehlen sich auch für andere Gehäuse anwendbare Lagerkörper, die nach einer besonderen Ausbildung der Erfindung eine Reihe von Stützstegen aufweisen, die von einem Basisteil des Lagerkörpers in Axialrichtung des Aufwickelorgans ein Stück weit abstehen und derart angeordnet sind, daß deren radial äußere Abstützflächen zur Abstützung der radial innen liegenden Mantelfläche des Gehäuses dienen. Mit anderen Worten: Die Stützstege sind längs eines Kreises angeordnet, dessen Radius etwas geringer ist als der Innenradius des hohlzylindrischen Gehäuses.Bearings that can be used for other housings are also recommended, the after a special training of the invention have a series of support webs by a base part of the bearing body in the axial direction of the winding member Stand out piece and are arranged so that their radial outer support surfaces to support the radially inside lying lateral surface of the housing. With others Words: The support webs are arranged along a circle, whose radius is slightly less than the inner radius of the hollow cylindrical housing.

Bei einer anderen Ausbildung des Lagerkörpers, der vor allem für solche Rollokassetten als Baueinheit bestimmt ist, bei denen der vom Gehäuse und Halteorgan umschriebene Wickelraum im wesentlichen rechteckförmig ist, dient wie schon oben ausgeführt mindestens einer der Lagerkörper, besser beide Lagerkörper an den Stirnseiten des Gehäuses nicht nur zum drehbaren Lager des Aufwickelorgans und zum Befestigen des Gehäuses, sondern zusätzlich in einer Mehrfachfunktion auch zum Befestigen der Einheit am Halteorgan und/oder an dem betreffenden Bauteil, an dem der Vorhang anzutreffen ist. Die Lagerkörper sind dann Verbindungsmittel für alle anderen Teile der Baueinheit. Die Rastverbindung wird durch den vom Lagerkörper insbesondere seitlich abstehenden Vorsprung hergestellt, welche in eine entsprechende Ausnehmung an der Innenseite des Halteorgans eingreift. Damit die Rast- bzw. Schnappverbindung zustande kommt, wird das entsprechende "Gegenlager" zweckmäßigerweise an einer solchen Stelle des Lagerkörpers und/oder des Gehäuses angeordnet, die sich in vergleichsweise großem Abstand zum Vorsprung befindet, so daß die federelastische Abspreizbarkeit des die Ausnehmung aufweisenden Schenkels des Halteorgans zu dem in das Gegenlager eingreifenden Schenkelteil des Halteorgans dieses Einschnappen begünstigt. Hierzu empfiehlt es sich nach einer besonderen Ausbildung der Erfindung, als Schwenklager für das Halteorgan einen entsprechenden Steg oder Ansatz an der Außenseite des Gehäuses oder Lagerkörper anzuordnen. In diesem Fall ist es überflüssig, daß die Bauteile miteinander verschraubt werden müssen, wodurch sich nicht nur ein ansprechenderes ästhetisches äußeres Erscheinungsbild mit vor allem glatten Flächen ergibt, sondern auch die Montage und Demontage wesentlich erleichtert und beschleunigt wird.With a different design of the bearing body, the one above all intended for such roller blind cassettes as a structural unit is in which the circumscribed by the housing and holding member Changing room is essentially rectangular, serves as before above at least one of the bearing bodies, better not only both bearing bodies on the front sides of the housing to the rotatable bearing of the rewinder and for fastening of the housing, but also in a multiple function also for fastening the unit to the holding member and / or to the concerned component on which the curtain can be found. The Bearing bodies are then connecting means for all other parts the unit. The locking connection is made by the bearing body especially protruding laterally manufactured, which in a corresponding Recess engages on the inside of the holding member. In order to the snap or snap connection is established, the corresponding "Counter bearing" expediently at such a point the bearing body and / or the housing arranged, which in comparatively large distance from the projection, so that the resilient spreadability of the recess having leg of the holding member to the in the counter bearing engaging leg part of the holding member this snap favored. It is recommended to do this after a special one Training of the invention, as a pivot bearing for that Holding member a corresponding web or approach on the outside to arrange the housing or bearing body. In this case it is unnecessary that the components are screwed together must be, which is not only a more appealing aesthetic outer appearance with above all smooth Surfaces results, but also the assembly and disassembly is significantly facilitated and accelerated.

Die federelastische Verankerung an der Rasteinrichtung wird durch entsprechende Dimensionierung und sich zu einem gewissen Grade federelastisch verhaltendes Material, beispielsweise Aluminium, für die Profilteile realisiert. Bei der Version von Figur 1 übernimmt der oben vom oberen Gehäuseschenkel 1c nach oben abstehende Steg 17 in Verbindung mit dem eine Auflauffläche bildenden und vom oberen Schenkel 2a des Halteorgans 2 nach unten abstehenden Steg 18 die Stützfunktion. The spring-elastic anchoring on the locking device is by appropriate sizing and to a certain extent resilient material, e.g. aluminum, realized for the profile parts. In the version of Figure 1 takes over the top of the upper housing leg 1c upwards projecting web 17 in connection with the one ramp surface forming and from the upper leg 2a of the holding member 2 web 18 projecting below the supporting function.

Gemäß Figur 2 ist eine bevorzugte Ausbildung im Querschnitt gezeigt. Danach ist der Innenraum des Gehäuses 1 im Querschnitt kreisförmig mit dem Radius R, das Gehaüse 1 weist also eine innere Mantelfläche 1 [mit im wesentlichen kreisformigen Querschnitt auf]. Die Wandstärke der beiden Mantelteile 1m und 1n nehmen jedoch von den schmalen Enden im Bereich der Durchtrittsöffnung 12 zu den breiteren Enden 1ml und 1nl im Bereich der Verbindungsstelle 1p zu. An dieser Verbindungsstelle 1p wird eine Art "Feder-Nut-Verbindung" 10 zwischen den beiden Mantelteilen 1a, 1b gebildet. Hierdurch wird beim Montieren ein Verrutschen bzw. radiales Verlagern der beiden Mantelteile 1m, 1n in Bezug zueinander verhindert, ehe eine genügende Verankerung am Lagerkörper 3 erzielt ist.According to Figure 2 is a preferred embodiment in cross section shown. Thereafter, the interior of the housing 1 is in cross section circular with the radius R, the housing 1 thus has an inner lateral surface 1 [with an essentially circular cross section]. The wall thickness of the two jacket parts However, 1m and 1n take from the narrow ends in the area the passage opening 12 to the wider ends 1ml and 1nl in the area of the junction 1p. At this junction 1p is a kind of "tongue and groove connection" 10 between the two jacket parts 1a, 1b formed. This will result in assembly a slipping or radial displacement of the two shell parts 1m, 1n in relation to each other prevented before a sufficient Anchoring to the bearing body 3 is achieved.

Bei der Ausbildung von Figur 2 weist der obere horizontale Schenkel 2a des Halteorgans 2 im Bereich des ein Schwenklager bildenden Lagersitzes an der Innenseite eine nasenförmige Erhebung 14a auf, wodurch beim Einführen des Vorsprungs 16b des freien Schenkelendes des T-förmigen Befestigungsstegs 16 in die Ausnehmung 15 am Fußpunkt des oberen Sperrsteges 14 eine bessere Führung im Lagersitz gewährleistet werden kann, wenn das Gehäuse 1 um dieses Schwenklager des Lagersitzes herum in den Zwischenraum zwischen die beiden horizontalen Schenkel 2a und 2c bis in den Lagersitz hineingeschwenkt und dort verrastet wird, der vom Sperrsteg 14 und der betreffenden Ausnehmung 15 am freien unteren Schenkelende gebildet wird, in die der Vorsprung 16a eingeschnappt wird. In the formation of Figure 2, the upper horizontal Leg 2a of the holding member 2 in the area of a pivot bearing bearing seat on the inside a nose-shaped elevation 14a, whereby when the projection 16b of the free Leg end of the T-shaped fastening web 16 into the recess 15 at the foot of the upper barrier 14 a better one Guidance in the bearing seat can be ensured if the housing 1 around this pivot bearing of the bearing seat in the space between the two horizontal legs 2a and 2c to in the bearing seat swung in and locked there, the from the barrier web 14 and the relevant recess 15 on the free lower leg end is formed, in which the projection 16a is snapped.

Das Halteorgan 2 und das Gehäuse 1 werden beispielsweise aus Aluminium hergestellt. Die Erfindung ist hierauf aber nicht beschränkt. Auch Kunststoffmaterialien sind hierfür geeignet.The holding member 2 and the housing 1 are made, for example Made of aluminum. However, the invention is not based on this limited. Plastic materials are also suitable for this.

Der Verbindungsschenkel 2b des Halteorgans 2 ist mittels der Befestigungsschraube 25 an der Wand W' angeschraubt, ehe die Rollokassette in die Montagestellung gebracht wird. Alternativ kann das Halteorgan 2 auch mittels des in unterbrochenen Linien angedeuteten Befestigungsorgans 26 oben angeschraubt werden, wodurch zusätzlich die Spannung auf die Lagersitze verstärkt wird. Zum Demontieren ist es lediglich erforderlich, die Rollokassette, d.h. das Gehäuse 1 ein Stück weit in Pfeilrichtung um das durch den Lagersitz bei 14a gebildete Schwenklager zu schwenken und den Druck der beiden Lagersitze auf den Befestigungssteg 16 zu überwinden, wodurch der untere Vorsprung 16a von seinem Lagersitz freikommt und dann die Rollokassette aus dem Halteorgan 2 herausgenommen werden kann.The connecting leg 2b of the holding member 2 is by means of Fixing screw 25 screwed to the wall W 'before the Rollo cassette is brought into the assembly position. Alternatively can the holding member 2 by means of the broken lines indicated attachment member 26 are screwed on top which additionally increases the tension on the bearing seats becomes. To dismantle it is only necessary to remove the roller cassette, i.e. the housing 1 a bit in the direction of the arrow around the pivot bearing formed by the bearing seat at 14a swivel and the pressure of the two bearing seats on the mounting web 16 to overcome, creating the lower projection 16a comes out of his camp seat and then the roller blind cassette can be removed from the holding member 2.

Gemäß Figur 3 ist das im Querschnitt im wesentlichen hohlzylindrische Gehäuse 1 über den Befestigungssteg - den Vorsprung 16 - ,der von einer Außenfläche des Gehäuses 1 absteht, im Halteorgan 2 gelagert, das entweder an der oberen Wand W oder alternativ an der Seitenwand W' einer Fensternische befestigt sein kann. Vom vertikalen Schenkel 2b stehen zwei Schenkel 2a, 2c gabelartig ab, so daß sich im Querschnitt im wesentlichen ein U-Profil ergibt mit einem längeren oberen Schenkel 2a und einem kürzeren unteren Schenkel 2c. An den Schenkelenden befinden sich als Lagersitze die Ausnehmungen 15.According to FIG. 3, the cross section is essentially hollow cylindrical Housing 1 over the fastening web - the projection 16 -, which protrudes from an outer surface of the housing 1, in the holding member 2 stored, either on the upper wall W or alternatively be attached to the side wall W 'of a window recess can. From the vertical leg 2b are two legs 2a, 2c fork-like, so that there is essentially a cross-section U-profile results with a longer upper leg 2a and one shorter lower leg 2c. Are located at the ends of the legs the recesses 15 as bearing seats.

In die obere rinnenförmige Ausnehmung 15 ist der Vorsprung 16b des T-förmigen Befestigungsstegs bzw. Vorsprung 16 des Gehäuses 1 eingesetzt. Da beide Schenkel 2a, 2c federelastisch sind, kann durch Druck der Vorsprung 16a des unteren freien Schenkelendes des Befestigungsstegs in die untere Ausnehmung 15 eingeschnappt werden. Durch die Durchtrittsöffnung 12 insbesondere in Form eines sich axial hinziehenden Schlitzes kann der Vorhang 4 mit Hilfe einer unteren Abschlußleiste 11 oder eines Gewichtes am unteren Ende des Vorhangs 4 aus dem Innenraum des Gehäuses 1 herausgezogen werden.In the upper groove-shaped recess 15 is the projection 16b of the T-shaped fastening web or projection 16 of the Housing 1 used. Since both legs 2a, 2c are resilient can by pressing the projection 16a of the lower free Leg end of the fastening web in the lower recess 15 are snapped. Through the passage opening 12 in particular in the form of an axially extending slot the curtain 4 with the help of a lower end strip 11 or a weight at the lower end of the curtain 4 from the interior the housing 1 are pulled out.

Ein bevorzugter Lagerkörper 3 ist schematisch in Figuren 4 und 5 gezeigt. Er schließt eine Stirnseite des im wesentlichen hohlzylindrischen Mantels des Gehäuses 1 ab. Ebenso wie sich der Haltezapfen 3b in Axialrichtung erstreckt, sind auch um jeweils 90° versetzt an der Innenseite des Lagerkörpers 3 angeordnete Stützsegmente bzw. Stützstege 3c ausgerichtet, an deren radial äußeren Abstützflächen 3c2 sich die radial innere Mantelfläche li mit dem Radius R abstützt. Die Gewindebohrungen 3cl dienen zum Festschrauben der beiden im wesentlichen im Querschnitt halbkreisförmigen Mantelteile 1m, 1n (Figur 2), die an einem Ende an der Verbindungsstelle 1p zusamenstoßen, sich am anderen Ende aber im Abstand voneinander befinden, um die Durchtrittsöffnung 12 für den Durchtritt des Vorhangs 4 zu formen. Jeder der beiden Mantelteile 1m, 1n wird durch eine Halteschraube X am Stützsteg 3c festgeschraubt, wodurch einerseits der Lagerkörper 3 mit dem Gehäuse 1 verbunden ist und die beiden Mantelteile lm, In andererseits durch den Lagerkörper 3 zusammengehalten werden. Auch hier befindet sich im Zentrum des im wesentlichen zylindrischen Aufnahmeraums 3d ein als Drehsicherung dienender Haltezapfen 3b und auch hier dienen im wesentlichen radial zur Achse des Haltezapfens 3b verlaufende Durchführungskanäle 3e zum Hindurchführen einer Zugschnur oder dergleichen.A preferred bearing body 3 is shown schematically in FIGS. 4 and 5 shown. It essentially closes one end of the from the hollow cylindrical shell of the housing 1. Just like the Retaining pins 3b extending in the axial direction are also around each 90 ° offset on the inside of the bearing body 3 arranged Support segments or support webs 3c aligned on the radial outer support surfaces 3c2 the radially inner lateral surface left with the radius R. The threaded holes 3cl serve to screw the two essentially in cross section semicircular shell parts 1m, 1n (Figure 2), on one Collide at junction 1p, at the other But end at a distance from each other to the passage opening 12 to form for the passage of the curtain 4. Everyone of the two jacket parts 1m, 1n is held by a retaining screw X screwed to the support web 3c, whereby on the one hand the bearing body 3 is connected to the housing 1 and the two jacket parts 1m, On the other hand, are held together by the bearing body 3. Here too is the center of the essentially cylindrical Recording room 3d a holding pin serving as a rotation lock 3b and also serve essentially radially to the axis of the retaining pin 3b extending through channels 3e Passing a pull cord or the like.

Die Gesamteinheit, bestehend aus beiden Mantelteilen 1m, 1n sowie zwei Lagerkörpern 3 an den Stirnseiten des Gehäuses 1 und dem im Inneren axial gelagerten Aufwickelorgan 5, bilden eine kassettenartige Baueinheit.The entire unit, consisting of two jacket parts 1m, 1n and two bearing bodies 3 on the end faces of the housing 1 and the winding member 5 axially mounted inside a cassette-like unit.

Mittels eines Körners ist gemäß Figur 6 eine Vertiefung an der Unterseite des mittleren Steges 3g zwischen den nach unten führenden Durchführungskanälen 3e aus dem zylindrischen Aufnahmeraum 3d angeordnet. Diese Vertiefung ist eine im wesentlichen kegelige Aussparung 3k. In die kegelige Aussparung 3k ist ein Vorsprung 1k des Gehäuses 1 eingedrückt, nachdem das Stirnende des Gehäuses 1 bis an den Basisteil 3f herangeführt ist. Der Vorsprung 1k wird beispielsweise mittels eines außen an der betreffenden Stelle auf das Gehäuse 1 aufgesetzten Preßdorns durch Eindrücken von Gehäusematerial in die vertiefte Aussparung 3k hergestellt. Die dabei entstehende dornartige Ausbeulung des Gehäusematerials, beispielsweise Aluminium, füllt die kegelige Aussparung 3k praktisch aus und stellt eine auf Abscherung beanspruchbare Verbindung zwischen dem Gehäuse 1 und dem Lagerkörper 3 her. Hierdurch wird ein Festschrauben des Gehäuses 1 auf beispielsweise den Stützstegen 3c überflüssig. Dennoch sitzt das Gehäuse 1 fest auf dem Lagerkörper 3, so daß eine feste Baueinheit hergestellt ist. Die Dicke des Lagerkörpers 3 kann auf beispielsweise die Hälfte vermindert werden, so daß die Durchführungskanäle 3e nach außen offen sind und sich durch diesen Verzicht auf geschlossene Durchführungskanäle einfacherere Druckgußformen für die Herstellung des Lagerkörpers 3 ergeben. Außerdem werden störende Schraubenköpfe an der Außenseite des Gehäuses 1 bzw. Lagerkörpers 3 vermieden. Es empfiehlt sich daher, die Durchführungskanäle 3e an der vom Basisteil 3f abgewandten Seite des Lagerkörpers 3 offen zu lassen. Der Haltezapfen 3b mit quadratischem Querschnitt dient als Drehsicherung, weist aber im Zentrum eine zylindrische Bohrung 3b1 auf.A recess on the underside of the middle web 3g between the lead-through channels leading downwards 3e arranged from the cylindrical receiving space 3d. This depression is essentially conical Recess 3k. A projection 1k of the housing is in the conical recess 3k 1 pressed in after the front end of the housing 1 to the Base part 3f is introduced. The protrusion 1k becomes, for example by means of an outside at the relevant point on the Housing 1 press mandrel by pressing in housing material made in the recessed recess 3k. The one there resulting thorn-like bulge of the housing material, for example Aluminum, practically fills the tapered recess 3k and provides a shearable connection between the housing 1 and the bearing body 3 ago. Hereby is a screwing of the housing 1 on, for example Support bars 3c unnecessary. Nevertheless, the housing 1 is firmly seated on the bearing body 3, so that a solid structural unit is produced is. The thickness of the bearing body 3 can be, for example, that Half be reduced so that the feed-through channels 3e are open to the outside and by not using closed feed-through channels easier die casting molds for the manufacture of the Bearing body 3 result. In addition, annoying screw heads on the outside of the housing 1 or bearing body 3 avoided. It is therefore recommended to use the feed-through channels 3e on the side of the bearing body facing away from the base part 3f 3 leave open. The holding pin 3b with a square cross section serves as a rotation lock, but has one in the center cylindrical bore 3b1.
