Description

Die Erfindung betrifft einen Abstandshalter für die Lamellenträger einer Vertikallamellenjalousie, bestehend aus einem länglichen, streifenförmigen Abschnitt, der an seinem Ende ein Verbindungselement zum formschlüssigen Eingriff mit einem Lamellenträger sowie einem an seinem freien anderen Ende einen Anschlag aufweist, welcher in Anlage mit dem benachbarten Lamellenträger führbar ist, wobei das Verbindungselement auf seiner dem Lamellenträger abgewandten Seite mit zwei einander gegenüberliegenden Nuten versehen ist, deren Abstand und Breite im wesentlichen den Dimensionen des streifenförmigen Abschnittes entspricht, wie er aus der DE-A-25 11 000 bekannt ist.The invention relates to a spacer for the slat carrier of a vertical slat blind, consisting of an elongated, strip-shaped section which has at its end a connecting element for positive engagement with a slat carrier and a stop at its free other end, which can be guided in contact with the adjacent slat carrier is, the connecting element is provided on its side facing away from the disk carrier with two mutually opposite grooves, the spacing and width essentially corresponds to the dimensions of the strip-shaped section, as is known from DE-A-25 11 000.

Vertikaljalousien dienen allgemein als Sonnen- und/oder Sichtschutz, sowie etwa als Raumteiler zur temporären Unter- oder Abteilung größerer Räume. Die im allgemeinen aus Textilmaterial bestehenden, streifenförmig ausgebildeten, vertikal angeordneten Lamellen sind jeweils an ihrem oberen Ende an einem Lamellenträger befestigt und im allgemeinen um eine mittlere Längsachse schwenkbar, wobei üblicherweise ein gleichzeitiges gemeinsames Verschwenken sämtlicher Lamellen einer Vertikaljalousie mittels eines Antriebes erfolgen kann. Die Lamellenträger sind in einer Tragschiene gehalten und mittels eines manuellen oder motorischen Antriebes entlang der Tragschiene verfahrbar. Das Verschwenken und das Verfahren kann durch zwei verschiedene Antriebe oder aber auch mittels eines Antriebes erfolgen.Vertical blinds generally serve as sun and / or privacy protection, as well as a room divider for temporary sub or division of larger rooms. The generally strip-shaped, vertically arranged slats, which are generally made of textile material, are each fastened at their upper end to a slat carrier and can generally be pivoted about a central longitudinal axis, with a common pivoting of all slats of a vertical blind by means of a drive usually being possible. The plate carriers are held in a mounting rail and can be moved along the mounting rail by means of a manual or motor drive. The pivoting and the movement can be carried out by two different drives or else by means of a drive.

In der Öffnungsstellung, in welcher das Fenster od. dgl. von den Lamellen nicht abgedeckt ist, sind die Lamellen an einer Seite zu einem Paket zusammengefahren, wobei die Lamellen zueinander parallel verlaufen. Soll das Fenster od. dgl. vollständig oder teilweise von den Lamellen der Vertikaljalousie abgedeckt werden, so wird der Verfahrantrieb betätigt. Dabei wird zunächst die vorn befindliche erste Lamelle in Bewegung gesetzt. Hat die erste Lamelle den vorgegebenen Abstand zu der ihr benachbarten zweiten Lamelle erreicht, so setzt sich die zweite Lamelle in Bewegung, bis schließlich sämtliche Lamellen verfahren worden sind und das Fenster entsprechend abgedeckt ist. Gleichzeitig oder anschließend lassen sich die Lamellen mittels des Schwenkantriebes um ihre Längsachsen verschwenken. der gegenseitige Abstand zwischen zwei einander benachbarten Lamellen im ausgefahrenen Zustand ist so bemessen, daß sich die Lamellen in der Schließstellung mit ihren einander benachbarten Randabschnitten überlappen, um einen Lichteinfall bzw. eine Einsicht von außen zu verhindern. Dieser gegenseitige Abstand zwischen jeweils zwei einander benachbarten Lamellen wird durch die eingangs genannten Abstandshalter sichergestellt, die jeweils zwischen einander benachbarten Lamellenträger angeordnet sind.In the open position, in which the window or the like is not covered by the slats, the slats are moved together on one side to form a package, the slats running parallel to one another. If the window or the like is to be completely or partially covered by the slats of the vertical blind, the traversing drive is actuated. First, the first slat in front is set in motion. When the first lamella has reached the predetermined distance from the adjacent second lamella, the second lamella starts to move until all the lamellae have been moved and the window is covered accordingly. At the same time or subsequently, the slats can be pivoted about their longitudinal axes by means of the swivel drive. the mutual distance between two adjacent slats in the extended state is dimensioned such that the slats overlap with their adjacent edge sections in the closed position in order to prevent incidence of light or insight from outside. This mutual distance between two mutually adjacent slats is ensured by the spacers mentioned at the outset, which are each arranged between mutually adjacent slat carriers.

Bei einem bekannten Abstandshalter der eingangs genannten Art ist das Verbindungselement am Ende des streifenförmigen Abschnittes auf der dem Lamellenträger zugewandten Seite mit einem Ansatz versehen, der in ein korrespondierendes Profil des Lamellenträgers eingreift. Auf der gegenüberliegenden Seite ist das Verbindungselement an seinen Rändern jeweils mit einem hochstehenden Flansch versehen, der in montiertem Zustand unter entsprechend vorstehende Flansche des Lamellenträgers greift, so daß eine feste formschlüssige Verbindung zwischen dem Abstandshalter und dem Lamellenträger bewirkt wird. Der Abstandshalter des benachbarten Lamellenträgers untergreift mit seinem streifenförmigen Abschnitt die vorerwähnten Flansche des Lamellenträgers und wird zwischen den Seitenflanschen des Verbindungselementes des ersten Abstandshalters geführt.In a known spacer of the type mentioned, the connecting element is provided at the end of the strip-shaped section on the side facing the disk carrier with a projection which engages in a corresponding profile of the disk carrier. On the opposite side, the connecting element is provided at its edges with an upstanding flange which, in the assembled state, engages under correspondingly projecting flanges of the disk carrier, so that a firm, form-fitting connection between the spacer and the disk carrier is effected. With its strip-shaped section, the spacer of the adjacent lamellar carrier engages under the aforementioned flanges of the lamellar carrier and is guided between the side flanges of the connecting element of the first spacer.

Beim Ausfahren des ersten Lamellenträgers gleitet der streifenförmige Abschnitt des Abstandshalters des zweiten Lamellenträgers unter den vorerwähnten Flanschen des ersten Lamellenträgers hindurch, bis der Anschlag am freien Ende des Abstandshalters mit den Flanschen zur Anlage kommt. Durch diesen kraftschlüssigen Eingriff wird in der durch den Abstandshalter bestimmten Distanz der zweite Lamellenträger mit dem ersten geführt, wobei nunmehr der streifenförmige Abschnitt des dritten Lamellenträgers unter den Flanschen des zweiten Lamellenträgers hindurchgleitet, bis dessen Endanschlag mit den Flanschen zur Anlage kommt usw. Hierdurch wird mit einfachen Mitteln die Einhaltung eines gleichmäßiogen Abstandes gewährleistet.When the first lamellar carrier is extended, the strip-shaped section of the spacer of the second lamellar carrier slides under the aforementioned flanges of the first lamellar carrier until the stop at the free end of the spacer comes into contact with the flanges. As a result of this non-positive engagement, the second disk carrier is guided with the first at the distance determined by the spacer, with the now strip-shaped section of the third disk carrier slides under the flanges of the second disk carrier until its end stop comes into contact with the flanges, etc. This ensures that a uniform distance is maintained with simple means.

Beim Öffnen vollziehen sich die Vorgänge in umgekehrter Reihenfolge. Nachdem der erste Lamellenträger unter Einschieben des streifenförmigen Abschnittes des Abstandshalters des zweiten Lamellenträgers unter den Flanschen des ersten Lamellenträgers zur Anlage gekommen ist, wird nunmehr der zweite Lamellenträger in Richtung auf den dritten verfahren, wobei sich dessen Abstandshalter nunmehr über die Flansche des zweiten Lamellenträgers schiebt. Hier zeigt sich ein gravierender Nachteil dieser bekannten Abstandshalter. Durch die Flansche der vorangehenden Lamellenträger, auf welche sich der streifenförmige Abschnitt des jeweils nachfolgenden Abstandshalters aufschiebt, wird dieser nach außen abgespreizt. Nach dem Zusammenführen bilden dementsprechend die Abstandshalter ein hahnenkammähnliches Bild, wobei sie an dem Innenprofil der Tragschiene anliegen und hier eine nachteilig bremsende Wirkung ausüben. Ein weiterer Nachteil der bekannten Abstandshalter liegt darin, daß jeweils das Verbindungselement eines einzelnen Abstandshalters in jeweils einen Lamellenträger eingeklinkt werden muß, worauf die Einzelelemente zu einer Lamellenträgergruppe zusammenzufügen sind. Hierdurch bedingt ist eine umständliche, zeit- und kostenaufwendige Montage.When opening, the processes take place in reverse order. After the first disc carrier has come into contact with the strip-shaped section of the spacer of the second disc carrier under the flanges of the first disc carrier, the second disc carrier is now moved in the direction of the third, the spacer now being pushed over the flanges of the second disc carrier. This shows a serious disadvantage of these known spacers. The flanges of the preceding lamellar carriers, onto which the strip-shaped section of the following spacer is pushed, spread this outwards. After the merging, the spacers accordingly form a cockscomb-like image, in which they rest on the inner profile of the mounting rail and exert a disadvantageously braking effect here. Another disadvantage of the known spacers is that the connecting element of an individual spacer must be latched into a respective plate carrier, whereupon the individual elements are to be assembled into a plate carrier group. This results in complicated, time-consuming and costly assembly.

Der Abstandshalter gemäß der DE-A-25 11 000 der hier in Rede stehenden Gattung ist an seinem Halterungsende lösbar mittels eines Knebels- bzw. Kreuzverschlusses an einem Lamellenträger festlegbar und gegenüber anderen vorbekannten Abstandshaltern deswegen einfacher montierbar bzw. auswechselbar, ohne daß die Gefahr einer Zerstörung bzw. Beschädigung des Abstandshalters gegeben ist, weil er nicht am Lamellenträger selbst sondern im vorhergehenden Abstandshalter geführt ist, wobei sein am anderen Ende angeordneter Anschlag hakenförmig ausgebildet ist, und zwar in der Ebene des Abstandshalters verlaufend etwa rechtwinklig abgebogen, so daß er bei maximal auseinander gezogenen Abstandshaltern als Anschlag mit einer dem hakenförmigen Anschlagabschnitt zugekehrten Stirnkante einer Führungsnut zusammenwirken kann. Auch bei diesem vorbekannten Abstandshalter kommt es indes zu einer vergleichbaren Problematik, wenn die Lamellen und damit ihre Lamellenträger bei ganz oder teilweise geöffneter Jalousie zu einem Paket zusammengeschoben sind, da die obere Abschlußfläche des Verbindungselementes wie bei anderen vorbekannten Abstandshaltern parallel zu dem streifenförmigen Abschnitt bzw. dessen Längsachse verläuft, so daß sich auch hier nach dem zusammenfahren ein hahnenkammähnliches Bild der freien Endabschnitte der Abstandshalter mit den bereits zuvor beschriebenen Wirkungen ergibt.The spacer according to DE-A-25 11 000 of the type in question is releasably fixable at its holder end by means of a toggle or cross lock on a lamellar carrier and therefore easier to assemble compared to other known spacers or replaceable, without the risk of destruction or damage to the spacer because it is not guided on the disk carrier itself but in the preceding spacer, its stop arranged at the other end being hook-shaped, namely in the plane of the spacer bent approximately at a right angle, so that it can interact as a stop with a spacer that is maximally pulled apart as a stop with an end edge of a guide groove facing the hook-shaped stop section. In this known spacer, too, there is a comparable problem if the slats and thus their slat carriers are pushed together to form a package when the blind is fully or partially open, since the upper end face of the connecting element, as in other known spacers, is parallel to the strip-shaped section or the longitudinal axis of which extends so that here, after moving together, a cockscomb-like image of the free end sections of the spacers results with the effects already described.

Angesichts dieser Problematik liegt der Erfindung die Aufgabe zugrunde, den Abstandshalter der eingangs genannten Art so auszugestalten, daß eine bremsende Wirkung durch abgespreizte streifenförmige Abschnitte der Abstandshalter innerhalb des Tragschienenprofils nicht zu befürchten ist, während sich andererseits die Montage wesentlich vereinfachen soll.In view of this problem, the invention has for its object to design the spacer of the type mentioned in such a way that a braking effect by spreading strip-shaped sections of the spacers within the mounting rail profile is not to be feared, while on the other hand the assembly is to be simplified considerably.

Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Kennzeichen des Hauptanspruches angegebenen Merkmale, wobei hinsichtlich bevorzugter Ausgestaltungen des erfindungsgemäßen Abstandshalters auf die Merkmale der Unteransprüche verwiesen wird.This object is achieved according to the invention by the features specified in the characterizing part of the main claim, reference being made to the features of the subclaims with regard to preferred configurations of the spacer according to the invention.

Bevorzugt ist das Verbindungselement des Abstandshalters in an sich bekannter Weise auf seiner dem Lamellenträger abgewandten Seite mit zwei aufeinander zugerichteten bzw. einander gegenüberliegenden Nuten versehen, deren Abstand und Breite im wesentlichen in Dimensionen des streifenförmigen Abschnittes des Abstandshalters entspricht. Damit kann der streifenförmige Abschnitt des jeweils nachfolgenden Abstandshalters in den Nuten des vorangehenden geführt werden. Diese Wirkung wird optimiert durch die dahingehende bevorzugte Ausgestaltung, daß die im Lamellenträger anliegende Grundfläche des Verbindungselementes zur Längsachse des streifenförmigen Abschnitts geneigt ist. Durch diese vorbestimmte Neigung legen sich beim Zusammenfahren der Lamellenträger die streifenförmigen Abschnitte zu einem kompakten Paket aufeinander. Eine zweckmäßige Neigung zwischen der Grundfläche und des streifenförmigen Abschnittes liegt zwischen etwa 5° und etwa 10°, wobei sich 6° als besonders zweckmäßig herausgestellt haben.The connecting element of the spacer is preferred Provide in a manner known per se on its side facing away from the disk carrier with two mutually facing or opposing grooves, the spacing and width of which corresponds essentially to the dimensions of the strip-shaped section of the spacer. The strip-shaped section of the following spacer can thus be guided in the grooves of the preceding one. This effect is optimized by the preferred embodiment in that the base surface of the connecting element lying in the plate carrier is inclined to the longitudinal axis of the strip-shaped section. As a result of this predetermined inclination, the strip-shaped sections lie one on top of the other to form a compact package when the lamella carriers move together. A suitable inclination between the base area and the strip-shaped section is between approximately 5 ° and approximately 10 °, 6 ° having proven to be particularly suitable.

Ein weiterer großer Vorteil der erfindungsgemäßen Ausgestaltung liegt darin, daß nunmehr etwa werksseitig eine beliebig lange Reihe von Abstandshaltern miteinander verbunden werden können. Die für eine bestimmte Fensterbreite erforderliche Anzahl wird nun einfach aus dieser Reihe ausgeklinkt und in zeitsparender Weise auf die entsprechende Anzahl von Lamellenträgern aufgeklipst.Another great advantage of the configuration according to the invention is that any number of spacers of any length can now be connected to one another at the factory. The number required for a certain window width is now simply released from this row and clipped onto the corresponding number of lamella supports in a time-saving manner.

Die Nuten erstrecken sich bevorzugt nur über einen Teilbereich des Verbindungselementes und zwar zweckmäßig nur über das vordere Drittel. Sie sind der Neigung der streifenförmigen Abschnitte angepaßt.The grooves preferably extend only over a partial area of the connecting element and expediently only over the front third. They are adapted to the inclination of the strip-shaped sections.

Die seitlichen Längslaschen des Verbindungselementes laufen bevorzugt zu dessen rückwärtigen Ende hinaus. Seitliche Vorsprünge im Bereich des Verbindungselementes greifen in korrespondierende Schlitze des Lamellenträgers ein.The lateral longitudinal tabs of the connecting element preferably run out to the rear end thereof. Lateral projections in the area of the connecting element engage in corresponding slots in the plate carrier.

Auf der dem Lamellenträger zugewandten Seite des Verbindungselementes sind, gemäß einer vorteilhaften Ausgestaltung, Rastnasen vorgesehen, zum formschlüssigen Eingriff mit dem Lamellenträger. Mindestens eine der Rastnasen ist zweckmäßig außen durch eine Schrägfläche begrenzt, wodurch der Einklinkvorgang erleichert wird. Am rückwärtigen Ende des Verbindungselementes ist vorteilhaft ein Queranschlag vorgesehen, der sich über die gesamte Breite des Verbindungselementes erstrecken kann. Der Queranschlag greift in eine entsprechende Aussparung des Lamellenträgers ein, so daß auch bei einem erhöhten Zug auf den Abstandshalter ein Ausgleiten nicht zu befürchten ist. Als besonders vorteilhaft hat sich erwiesen, die Abstandshalter in einer Profilnische auf der Unterseite des Lamellenträgers zu halten. Es ergibt sich damit eine verbesserte Raumausnutzung des Innenprofils der Tragschiene.According to an advantageous embodiment, locking lugs are provided on the side of the connecting element facing the plate carrier for positive engagement with the plate carrier. At least one of the locking lugs is expediently delimited on the outside by an inclined surface, which makes the latching process easier. At the rear end of the connecting element, a transverse stop is advantageously provided, which can extend over the entire width of the connecting element. The transverse stop engages in a corresponding recess in the lamellar carrier, so that there is no fear of slipping even when there is an increased pull on the spacer. It has proven to be particularly advantageous to hold the spacers in a profile niche on the underside of the disk carrier. This results in an improved Utilization of the inner profile of the mounting rail.

Eine über eine Welle manuell oder motorisch angetriebene Schnecke 16 steht mit dem Ritzel 14 in Eingriff. Über eine Drehung der Schnecke 16 läßt sich die Winkelposition der Lamellenhalterung 15 und dementsprechend der hieran befestigten, im einzelnen nicht dargestellten Vertikallamelle einstellen. Hakenförmige Gleitvorsprünge 17, 18 und 19 greifen an entsprechend profilierten Gleitflächen im Querschnittsbereich der Tragschiene an. Ein über einen Steg 20 axial versetzter Querriegel 21 gleitet in einer Profilnische der Tragschiene und hält das Gehäuse in einer Ebene senkrecht zur Längsachse der Tragschiene und verhindert somit ein Verkanten.The spacer shown in FIG. 1 and shown in its entirety with the reference number 10 is latched in the manner shown in a profile niche of a plate carrier generally designated 11. The function of the slat carrier will be briefly explained below. A vertical axis 13 is mounted in the housing 12, which carries a pinion 14, which is hereby made of the same material, in the middle region, while down a lamella bracket 15 protrudes beyond the housing 12. A worm 16 which is driven manually or by a motor via a shaft is in engagement with the pinion 14. By rotating the worm 16, the angular position of the lamella holder 15 and, accordingly, the vertical lamella, not shown, can be adjusted. Hook-shaped sliding projections 17, 18 and 19 engage correspondingly profiled sliding surfaces in the cross-sectional area of the mounting rail. A cross bar 21 axially offset via a web 20 slides in a profile niche of the mounting rail and holds the housing in a plane perpendicular to the longitudinal axis of the mounting rail and thus prevents tilting.

Der in Fig. 2 wiedergegebene Abstandshalter 11 umfaßt einen länglichen streifenförmigen Abschnitt 22, einen vorderern Anschlag 23, sowie ein Befestigungselement 24, das nachfolgend anhand der Figuren 3 bis 5 noch näher erläutert werden soll. Obwohl der Abstandshalter auch aus Metall bestehen kann, ist er bevorzugt aus Kunststoff gefertigt, da dieser leicht, kostengünstig und flexibel ist, während er sich außerdem in relativ einfacher Weise der gewünschten Formgebung unterziehen läßt.The spacer 11 shown in FIG. 2 comprises an elongated strip-shaped section 22, a front stop 23, and a fastening element 24, which will be explained in more detail below with reference to FIGS. 3 to 5. Although the spacer can also consist of metal, it is preferably made of plastic, since this is light, inexpensive and flexible, while it can also be subjected to the desired shape in a relatively simple manner.

Das Querschnittsprofil des Befestigungselementes 24 ergibt sich aus der Darstellung gemäß Figur 3. Der streifenförmige Abschnitt 22 besitzt entlang seiner Längskanten doppelseitige Anfasungen 25. Der Abschnitt 22 ist materialeinheitlich mit dem Anschlag 23 sowie dem Befestigungselement 24 gefertigt. Von der unteren Fläche des Befestigungselementes 24 ragen seitliche Längsflansche 26 und 27 vor, die entlang ihrer Außenkante nach innen gerichtete, im Querschnitt im wesentlichen dreieckförmige Vorsprünge 28 und 29 tragen. Die Vorsprünge 28 und 29 erstrecken sich, wie aus Fig. 5 deutlich wird, lediglich etwa über das erste Drittel der Längsflansche 26 und 27,vom Abschnitt 22 ausgehend. Die Längsflansche 26 und 27 laufen zum rückwärtigen Ende des Verbindungselementes 24 hin aus.The cross-sectional profile of the fastening element 24 results from the illustration according to FIG. 3. The strip-shaped section 22 has double-sided bevels 25 along its longitudinal edges. The section 22 is made of the same material as the stop 23 and the fastening element 24. Lateral longitudinal flanges 26 and 27 protrude from the lower surface of the fastening element 24 and carry projections 28 and 29 which are directed inward along their outer edge and are essentially triangular in cross section. As is clear from FIG. 5, the projections 28 and 29 only extend over approximately the first third of the longitudinal flanges 26 and 27, starting from the section 22. The longitudinal flanges 26 and 27 run to rear end of the connecting element 24 out.

Aus Fig. 3 wird weiterhin deutlich, daß das Verbindungselement 24 seitliche Längsvorsprünge 30 und 31 trägt, die in entsprechende Nuten des Gehäuseprofils des Lamellenträgers 11 eingreifen, um eine sichere Verbindung zwischen dem Gehäuse 12 des Lamellenträgers 11 und dem Abstandshalter 10 herzustellen. Hierzu tragen außerdem Rastnasen 32 und 33 bei, die aus der oberen Abschlußfläche 34 des Verbindungselementes 24 vorragen. Die vordere Rastnase 32 besitzt eine schräge obere Abschlußfläche, die zur Abschlußfläche 34 hin ausläuft.From Fig. 3 it is also clear that the connecting element 24 carries lateral longitudinal projections 30 and 31 which engage in corresponding grooves of the housing profile of the disk carrier 11 in order to produce a secure connection between the housing 12 of the disk carrier 11 and the spacer 10. Also contribute to this locking lugs 32 and 33, which protrude from the upper end surface 34 of the connecting element 24. The front locking lug 32 has an oblique upper end surface which tapers towards the end surface 34.

Entlang der rückwärtigen Kante des Befestigungselementes ist auf der oberen Abschlußfläche 34 ein rückwärtiger Queranschlag 35 vorgesehen, der sich über die gesamte Breite des Verbindungselementes 24 erstreckt. Die Rastnasen 32 und 33 sowie der rückwärtige Queranschlag 35 sind materialeinheitlich mit dem gesamten Abstandshalter 10 gefertigt.Along the rear edge of the fastening element, a rear transverse stop 35 is provided on the upper end face 34, which extends over the entire width of the connecting element 24. The detents 32 and 33 and the rear cross stop 35 are made of the same material with the entire spacer 10.

Beim Anklipsen des Abstandshalters 10 an dem Lamellenträger 11 wird, wie dies die Fig. 1 zeigt, entsprechend der Richtung des Pfeiles 36 der streifenförmige Abschnitt 22 des Abstandshalters 10 von hinten in die Profilnische des Lamellenträgers 11 eingeführt. Die seitlichen Längsvorsprünge 30 und 31 des Verbindungselementes 24 greifen in seitliche Nuten der Profilnische des Lamellenträgers 11 ein. Bei stärkerem Zug gleitet die vordere Rastnase 32, die infolge der Elastizität des Materials zusammen mit dem Verbindungselement 24 federnd nachgibt, über einen Vorsprung der Profilnische des Lamellenträgers und hintergreift diesen, wobei der Queranschlag 35 mit einem entsprechenden Anschlag der Profilnische zur Anlage kommt.When the spacer 10 is clipped onto the disk carrier 11, as shown in FIG. 1, the strip-shaped section 22 of the spacer 10 is inserted into the profile niche of the disk carrier 11 from behind in accordance with the direction of the arrow 36. The lateral longitudinal projections 30 and 31 of the connecting element 24 engage in lateral grooves in the profile niche of the plate carrier 11. In the event of a stronger pull, the front detent 32, which yields resiliently together with the connecting element 24 as a result of the elasticity of the material, slides over a projection of the profile recess of the disk carrier and engages behind it, the transverse stop 35 coming into contact with a corresponding stop of the profile recess.

Die obere Abschlußfläche 34 des Verbindungselementes 24 schließt mit der Längsachse des streifenförmigen Abschnittes 22 einen Winkel α von etwa 6° ein, wie dies in Fig. 5 angedeutet ist. Dementsprechend liegen die streifenförmigen Abschnitte aller Abstandshalter bei zu einem Paket zusammengefahrenen Lamellenträgern schuppenförmig dicht aufeinander. Dabei gleitet bzw. liegt der streifenförmige Abschnitt des jeweils nachfolgenden Abstandshalters in den durch die Längsvorsprünge 28 und 29 gebildeten Nuten 37 und 38 des Verbindungselementes.The upper end face 34 of the connecting element 24 encloses an angle α of approximately 6 ° with the longitudinal axis of the strip-shaped section 22, as is indicated in FIG. 5. Correspondingly, the strip-shaped sections of all spacers lie in a lamellar manner, one above the other, in the case of lamellar carriers brought together in a package. The strip-shaped section of the following spacer slides or lies in the grooves 37 and 38 of the connecting element formed by the longitudinal projections 28 and 29.

Es sei noch nachgetragen, daß der Abstandshalter 10 zur besseren Paketierung vor dem Einbau und vor dem Ausklinken aus dem Abstandshalter-"Paket" so ausgebildet ist, daß die einzelnen Abstandshalter durch ein leichtes Anbiegen des Verbindungselementes 24 besonders einfach zu verbinden sind. Aus diesen Grunde ist die Anordnung so getroffen, daß die Hauptebene des Verbindungselementes 24 unter einem spitzen Winkel von wenigen Grad zur Ebene des streifenförmigen Abschnittes 22 verläuft.It should be added that the spacer 10 for better packaging before installation and before releasing from the spacer "package" is designed so that the individual spacers are particularly easy to connect by slightly bending the connecting element 24. For this reason, the arrangement is such that the main plane of the connecting element 24 extends at an acute angle of a few degrees to the plane of the strip-shaped section 22.

Weiterhin sei nachgetragen, daß der streifenförmige Abschnitt 22 an seinem das Verbindungselement 24 tragenden Endabschnitt mit Abstand von seinem dortigen Ende an seinen beiden Längsrändern mit Aussparungen 39 versehen ist.It should also be added that the strip-shaped section 22 is provided with recesses 39 on its end section carrying the connecting element 24 at a distance from its end there on its two longitudinal edges.

Es soll an dieser Stelle noch einmal ausdrücklich hervorgehoben werden, daß es sich bei der vorangehenden Beschreibung lediglich um eine solche beispielhaften Charakters handelt, und daß verschiedene Modifikationen und Abänderungen möglich sind, ohne dabei den Rahmen der Erfindung gemäß der Ansprüche zu verlassen. So läßt sich im besonderen die Profilierung der Rastnasen 32 und 33 sowie des rückwärtigen Queranschlages 35 anders ausgestalten, wobei sich die gleiche Wirkung erzielen läßt.At this point, it should again be expressly emphasized that the foregoing description is merely of an exemplary character and that various modifications and changes are possible without leaving the scope of the invention according to the claims. In particular, the profiling of the locking lugs 32 and 33 and the rear transverse stop 35 can be designed differently, the same effect being able to be achieved.
