Description

Die Erfindung bezieht sich auf ein Spannband, insbesondere zum Binden langgestreckter Gegenstände wie Kabelbäume, bestehend aus einer beiderseits gezahnten Bandzunge, aus einem Klemm­keil, der an seinem dünneren Ende mit einem Ende der Bandzunge verbunden und an beiden Keilflächen gezahnt ist, und aus einem Klemmkopf, der zur Aufnahme des Klemmkeils und des zu klemmen­den, freien Endes der Bandzunge eine Klemmöffnung enthält, die auf gegenüberliegenden Seiten von konvergierenden Öffnungs­flächen begrenzt ist, von denen jeweils eine zur Abstützung des Klemmkeils an einer seiner Keilflächen und die andere gemeinsam mit der anderen Keilfläche zur Bildung eines Klemm­spalts für die Bandzunge bestimmt ist.The invention relates to a tension band, in particular for binding elongated objects such as cable harnesses, consisting of a band tongue serrated on both sides, a clamping wedge which is connected at its thinner end to one end of the band tongue and serrated on both wedge surfaces, and a clamping head, which for receiving the clamping wedge and the free end of the band tongue to be clamped contains a clamping opening which is delimited on opposite sides by converging opening surfaces, one of which is used to support the clamping wedge on one of its wedge surfaces and the other together with the other wedge surface for formation a clamping gap is intended for the band tongue.

Bei Spannbändern, deren Bandzunge mittels eines Klemmkeils in der konvergierenden Klemmöffnung des Klemmkopfs gehalten ist, beruht die Klemmwirkung darauf, daß der Klemmkeil mit wachsen­der Bandspannung zunehmend in die Klemmöffnung hineingezogen und dadurch die Klemmkraft verstärkt wird. bei einem bekannten Spannband der eingangs genannten Art (DE-GM 82 31 443) wird die Bandspannung einerseits durch die unmittelbare Verbindung mit dem einen Ende der Bandzunge auf den Klemmkeil übertragen. Andererseits findet auch eine Kraftübertragung von dem freien, geklemmten Ende der Bandzunge auf den Klemmkeil statt, weil dieser gezahnt ist. Bei der Montage des Spannbands findet die anfängliche Klemmung dadurch statt, daß der Klemmteil infolge seiner unmittelbaren Verbindung mit einem Ende der Bandzunge in die Klemmöffnung hineingezogen wird und dadurch die Zahnungen des Klemmteils und der Bandzunge im Klemmspalt miteinander in Eingriff kommen. Wenn aber nach der Montage das Spannband lose bleibt, was auf einem Versehen oder in manchen Fällen auch auf Absicht beruhen kann, besteht die Gefahr, daß der Klemmkeil nicht in die Klemmöffnung hineingezogen ist und dadurch die Zahnungen von Klemmkeil und Bandzunge außer Eingriff bleiben, so daß die Bandzunge aus dem Klemmspalt herausgezogen werden kann. Zwar ist es bekannt, den Klemmkopf und das Spannband nahe dem Klemmkeil mit zusammenwirkenden Anschlägen zu versehen (US-A-3 654 669); jedoch sind die Anschläge so weit von dem Klemmkeil entfernt, daß dieser nicht daran gehindert wird, eine Stellung vollständiger Lösung einzunehmen.In the case of tensioning straps, the strap tongue of which is held in the converging clamping opening of the clamping head by means of a clamping wedge, The clamping effect is based on the fact that the clamping wedge is increasingly drawn into the clamping opening with increasing belt tension and the clamping force is thereby increased. in a known strap of the type mentioned (DE-GM 82 31 443), the strap tension is transmitted on the one hand by the direct connection to one end of the tongue on the clamping wedge. On the other hand, there is also a power transmission from the free, clamped end of the band tongue to the clamping wedge because it is toothed. When the tensioning strap is assembled, the initial clamping takes place in that the clamping part is drawn into the clamping opening as a result of its direct connection to one end of the band tongue, and the teeth of the clamping part and the band tongue come into engagement with one another in the clamping gap. If, however, the strap remains loose after assembly, which can be due to an accident or in some cases also on purpose, there is a risk that the clamping wedge is not drawn into the clamping opening and the teeth of the clamping wedge and the strap tongue remain disengaged, so that the band tongue can be pulled out of the clamping gap. It is known to provide the clamping head and the clamping band near the clamping wedge with cooperating stops (US Pat. No. 3,654,669); however, the stops are so far from the wedge that it is not prevented from assuming a full solution position.

Der Erfindung liegt die Aufgabe zugrunde, ein Spannband der eingangs genannten Art zu schaffen, bei dem der Zahneingriff auch dann gewährleistet ist, wenn nach der Montage nicht die volle Bandspannung wirkt. Die erfindungsgemäße Lösung besteht darin, daß die Öffnungsflächen des Klemmkopfs eine Federzunge aufweisen, die nachgiebig in die Klemmöffnung vortritt und von denen jeweils eine Kante des Klemmkeils hintergreift.The invention has for its object to provide a strap of the type mentioned, in which the tooth engagement is guaranteed even if the full strap tension does not act after assembly. The solution according to the invention is that the opening surfaces of the clamping head have a spring tongue, which resiliently protrudes into the clamping opening and each of which engages behind an edge of the clamping wedge.

Zweckmäßigerweise ist dabei die Öffnungsfläche der Federzunge oder diese mit der sich anschließenden Öffnungsfläche des Klemmkopfs im wesentlich konkav, so daß der Klemmkeil, wenn er in den Klemmkopf hineingezogen aber doch nicht unter voller Spannung steht, von den vom Klemmkopf einschließlich der Federzungen gebildeten Öffnungsflächen in einer Art Höhlung gehalten ist, die sich hinter dem Klemmkopf (oder wenigstens einer Kante des Klemmkopfs) verengt.Appropriately, the opening area of the spring tongue or this is essentially concave with the subsequent opening area of the clamping head, so that the clamping wedge, when it is drawn into the clamping head but is not under full tension, of the opening areas formed by the clamping head including the spring tongues in one Type of cavity is kept, which narrows behind the clamping head (or at least one edge of the clamping head).

Die Rückhaltewirkung der Federzungen kann dadurch noch weiter verbessert werden, daß sie wenigstens am Ende einen mit der Zahnung des Klemmkeils zusammenwirkenden Zahn aufweisen, vorzugsweise sogar auf ihrer gesamten Öffnungsfläche gezahnt sind. Darüber hinaus sollen die Öffungsflächen des Klemmkopfs auch in demjenigen Bereich gezahnt sein, der nicht in Gestalt der Federzungen federnd ausgebildet ist, wobei der Klemmkeil im gespannten Zustand sich zu einem wesentlichen Teil wenn nicht sogar vollständig in diesem nicht federnden Bereich der Öffnungsfläche abstützt. Dadurch wird erzielt, daß die Feder­zungen durch die am Klemmkeil aufzubringende Stützkraft nicht oder nur wenig beaufschlagt werden und sich daher im gespannten Zustand auch nicht wesentlich bleibend verformen, um auch dann noch im Falle einer zufälligen Lockerung des Bandes ihre Rückhaltewirkung ausüben zu können. Statt dessen kann auch vorgesehen sein, daß die Federzungen und der hinter ihnen liegende Teil des Klemmkopfs mit zusammenwirkenden Abstützflächen ausgerüstet sind, die dafür sorgen, daß die Federzungen unter der Klemmkraft nur so weit zurückgedrückt werden können, daß ihre Zahnung noch in wirksamen Rückhalte­eingriff mit dem Klemmkeil gelangen können.The retention effect of the spring tongues can be further improved in that at least at the end they have a tooth which interacts with the toothing of the clamping wedge, preferably even being serrated over their entire opening area. In addition, the opening surfaces of the clamping head should also be serrated in the area which is not designed to be resilient in the form of the spring tongues, the clamping wedge in the tensioned state being supported to a substantial extent, if not completely, in this non-resilient area of the opening area. This ensures that the spring tongues are not or only slightly acted upon by the supporting force to be applied to the clamping wedge and therefore do not deform significantly in the tensioned state, so that they can still exert their restraining effect in the event of an accidental loosening of the band. Instead, it can also be provided that the spring tongues and the part of the clamping head behind them are equipped with cooperating support surfaces which ensure that the spring tongues can only be pushed back under the clamping force to such an extent that their teeth are still in effective retention engagement with the Wedge can get.

Die Erfindung wird im folgenden näher unter Bezugnahme auf die Zeichnung erläutert, die in

  • Fig.1 einen Längsschnitt durch die Verschlußteile des Spannbands in lockerem und in
  • Fig.2 im gespannten Zustand darstellt.
The invention is explained in more detail below with reference to the drawing which in
  • 1 shows a longitudinal section through the closure parts of the strap in a loose and in
  • Fig.2 shows in the tensioned state.

Das Spannband, das - soweit hier nicht anders erläutert - zweckmäßigerweise von der Art ist, wie sie in der EP-A 0 125 637 erläutert ist, umfaßt eine Bandzunge 1, an deren einem Ende der Klemmkeil 2 einstückig angeordnet ist, während das andere, freie Ende durch den Klemmspalt 3 geführt ist, der in dem Klemmkopf 4 in dessen Klemmöffnung 5 gebildet wird. Die Klemmöffnung wird auf gegenüberliegenden Seiten begrenzt durch nach (in der Zeichnung) unten konvergierende, gezahnte Öffnungsflächen 6 und 7. Diesen stehen auf seiten des Klemmkeils 2 gezahnte Keilflächen 8 bzw. 9 gegenüber. Die Keilfläche 8 des Klemmkeils stützt sich an der Öffnungsfläche 6 des Klemmkopfs ab, während die Keilflächen 7 und die Öffnungsflächen 9 den Klemmspalt 3 und darin das freie Ende der Bandzunge 1 einschließen. Dabei ist es gleichgültig, ob das freie Ende der Bandzunge 1 zwischen den Klemmflächen 7 und 9 oder zwischen den Klemmflächen 6 und 8 eingeschoben wird, was eine beträchtliche Montage-Erleichterung bedeutet, weil das Spannband blind montiert werden kann.The tensioning strap, which - unless otherwise stated here - is expediently of the type described in EP-A 0 125 637, comprises a strap tongue 1, at one end of which the clamping wedge 2 is arranged in one piece, while the other, free end is guided through the clamping gap 3, which is formed in the clamping head 4 in the clamping opening 5. The clamping opening is delimited on opposite sides by toothed opening surfaces 6 and 7 converging downwards (in the drawing). These are opposed by toothed wedge surfaces 8 and 9 on the side of the clamping wedge 2. The wedge surface 8 of the clamping wedge is supported on the opening surface 6 of the clamping head, while the wedge surfaces 7 and the opening surfaces 9 enclose the clamping gap 3 and therein the free end of the band tongue 1. It does not matter whether the free end of the strap tongue 1 is inserted between the clamping surfaces 7 and 9 or between the clamping surfaces 6 and 8, which means a considerable ease of assembly, because the tensioning strap can be installed blind.

Im Bereich der Öffnungsflächen 6 und 7 sind Federzungen 10, 11 vorgesehen, die im dargestellten Beispiel den oberen Teil der Öffnungsflächen 6 und 7 bilden. Im entspannten Zustand (Fig.1) stehen die Federzungen ein wenig in die Klemmöffnung 5 vor, und zwar so weit, daß der neben dem Klemmkeil 2 verbleibende Klemmspalt 3 selbst dann nicht weiter ist, als die Dicke der Bandzunge 1, wenn die Anordnung entspannt ist und der Klemm­keil 2 ein wenig nach oben im Klemmkopf 4 verschoben ist. Es kann am unteren Ende des Klemmkeils oder am Spannband ein Anschlag vorgesehen sein, der mit der Unterfläche des Klemm­kopfs 4 derart zusammenwirkt, daß der Klemmkeil nur so weit aus dem Klemmkopf heraustreten kann, daß die Wirkung der Klemmzungen noch gewährleistet ist.In the area of the opening surfaces 6 and 7, spring tongues 10, 11 are provided, which form the upper part of the opening surfaces 6 and 7 in the example shown. In the relaxed state (FIG. 1), the spring tongues protrude a little into the clamping opening 5, to the extent that the clamping gap 3 remaining next to the clamping wedge 2 is no further than the thickness of the strip tongue 1 when the arrangement relaxes and the clamping wedge 2 is shifted a little upwards in the clamping head 4. It can be on the lower end of the wedge or on the strap Stop is provided, which cooperates with the lower surface of the clamping head 4 such that the clamping wedge can only come out of the clamping head so far that the effect of the clamping tongues is still guaranteed.

Die Rückhaltewirkung der Klemmzungen wird dadurch intensiviert, daß sie in dem gezeigten Länggschnitt konkav sind, was insbesondere bei der in Fig.1 rechten Klemmzunge erkennbar ist. Infolge der Konkavität wird der Klemmkeil ganz oder wenigstens bis der durch den Zahn 12 bebildeten, nach hinten gewendeten Kante von der Federzunge unfaßt, wobei der Endzahn 13 der Federzunge hinter den Zahn 12 faßt.The retention effect of the clamping tongues is intensified by the fact that they are concave in the longitudinal section shown, which can be seen in particular in the clamping tongue on the right in FIG. As a result of the concavity, the clamping wedge is completely or at least up to the edge turned by the tooth 12 and turned backwards by the spring tongue, the end tooth 13 of the spring tongue reaching behind the tooth 12.

Wird aus diesem Zustand heraus die freie Bandzunge nach unten (in der Zeichnung) gezogen, so wird durch ihren Eingriff mit den Zähnen des Klemmkeils 2 sichergestellt, daß dieser der Bewegung folgt, bis schließlich vollständige Klemmung eintritt, wie in Fig.2 dargestellt. In der Klemmstellung stützt sich der Klemmkeil 2 einerseits auf der dem Klemmspalt abgewandten Seite an der Öffnungsfläche 6 ab und wird andererseits Keilkraft aus das freie Ende der Bandzunge 1 ausgeübt, die von der Öffnungsfläche 7 aufgenommen wird. Die Abstützung des Klemmkeils bzw. des Spannbands durch die Öffnungsflächen 6,7 findet dabei hauptsächlich nahe oder unterhalb der Wurzel 14 der Federzungen statt, so daß diese nicht oder nur wenig verformt werden und daher selbst dann, wenn sie aus einem Kunststoff mit nachlassender Rückstellkraft bestehen, im Falle einer zufälligen Lockerung des Bandes für die Zurückhaltung des Klemmkeils wirksam sind. Wichtig ist somit in diesem Zusammenhang, daß sich nur ein Teil der Zähne des Klemmkopfs an der Federzunge befindet, während die unteren Zähne außerhalb des Federzungenbereichs starr am Klemmkopf angeordnet sind. Verbindet man die Spitzen sämtlicher Zähne miteinander, so ergibt sich zumindest im ungespannten, vorzugsweise auch im gespannten Zustand, eine gekrümmte Linie, die von unten nach oben mehr und mehr in die Klemmöffnung vordringt.If the free band tongue is pulled down (in the drawing) from this state, its engagement with the teeth of the clamping wedge 2 ensures that it follows the movement until complete clamping occurs, as shown in FIG. In the clamping position, the clamping wedge 2 is supported on the one hand on the side facing away from the clamping gap on the opening surface 6 and, on the other hand, wedge force is exerted from the free end of the band tongue 1, which is received by the opening surface 7. The support of the clamping wedge or the tensioning band by the opening surfaces 6, 7 takes place mainly near or below the root 14 of the spring tongues, so that these are not or only slightly deformed and therefore even if they consist of a plastic with a decreasing restoring force , are effective in the event of accidental loosening of the band for the retention of the clamping wedge. It is therefore important in this context that only a part of the teeth of the clamping head is located on the spring tongue, while the lower teeth are arranged rigidly on the clamping head outside the spring tongue area. If you connect the tips of all the teeth together, at least in the untensioned, preferably also in the tensioned state, a curved line that penetrates more and more into the clamping opening from bottom to top.
