Description

Die Erfindung bezieht sich auf eine Klemmeinrichtung zum selbstsichernden Verspannen und Verkürzen von Gurten mit einem festen und einem freien Gurtende und dgl. mit einem Halteteil und einem zu diesem verschiebbar gelagerten Klemmteil, welches bei Zugbeanspruchung eine Verklemmung des freien Gurtendes bewirkt.The invention relates to a clamping device for self-locking tensioning and shortening of belts with a fixed and a free end of the belt and the like. With a holding part and a displaceably mounted clamping part, which causes the free end of the belt to jam under tensile stress.

Derartige Klemmeinrichtungen sind in unterschiedlichen Ausführungsformen bekannt. Sie bestehen im allgemeinen aus mindestens zwei einzelnen Klemmteilen, die durch die Gurtumschlingung als Einheit verbunden werden. Dabei bauen die als Klemmteile vorgesehenen Bauelemente relativ hoch, so daß insbesondere bei im Stapel ver­wendeten verspannten Gegenständen die eigentliche Klemm­einrichtung den Umfang dieses Stapels übermäßig über­ragt und zu Beschädigungen der benachbarten eingestapel­ten Gegenstände führt. Andererseits sind die Spannteile auch in Richtung des zu verspannenden Gurtes relativ groß ausgelegt, so daß auch auf der zu verspannenden Umfangsfläche Beschädigungen erwartet werden müssen.Such clamping devices are known in different embodiments. They generally consist of at least two individual clamping parts which are connected as a unit by the belt wrap. The components provided as clamping parts build relatively high, so that, in particular in the case of clamped objects used in the stack, the actual clamping device projects excessively beyond the circumference of this stack and leads to damage to the adjacent stacked objects. On the other hand, the tensioning parts are also designed to be relatively large in the direction of the belt to be tensioned, so that damage must also be expected on the circumferential surface to be tensioned.

Aus der US-A-3,277,543 ist eine Klemmeinrichtung be­kanntgeworden, die aus einem Halteteil und einem Klemm­teil gebildet ist und einen Quersteg aufweist, an welchem das freie Gurtende umlegbar ist. Eine Klem­mung im Sinne der vorliegenden Erfindung findet jedoch mit diesem Quersteg und dem zugeordneten Steg des Halte­teils nicht statt. In Arbeits-, also Klemmposition, be­steht ein deutlicher Abstand zwischen dem Steg und dem Halteteil. Dabei liegt das freie, nicht vom Gurt um­schlossene Ende des Klemmteils mit dem durch die Öffnung gezogenen Gurt auf der Oberfläche des Gurtendes auf und ist demzufoïge in dieser Spannposition nicht weiter nach unten bewegbar, so daß auch bei einer weiteren Spann­möglichkeit, also ein weiteres Anziehen des Gurtendes, immer ein Abstand zwischen dem Steg und dem Halteteil ver­bleibt. Die Folge ist, daß der Gurt in allen Berührungs­punkten mit dem Klemmteil und dem Halteteil sowie der aufliegenden Schlaufe des Gurtes lediglich unter Haft­reibung gehalten wird, die je nach Ausbildung solcher Gurte relativ schnell in eine Gleitreibung übergehen kann. Hier ist insbesondere der rauhe Alltagsbetrieb bei Verwendung solcher Gurte zu berücksichtigen, bei welchem häufig durch Schmierfette und dgl. behaftete Band- bzw. Gurtoberflächen nicht ausgeschlossen werden können. Insbesondere bei dem Umsetzen und Spannen von Stahlteilen, die häufig einen Korrossionsschutzfilm bzw. durch die Herstellung bedingte Oberflächenrück­stände aufweisen, sind derartige Gurtoberflächen in äußerst kurzer Zeit entsprechend ebenfalls mit einem Schmierfilm belegt, der die vorgenannte Gleitreibung entsprechend beschleunigt und derartige Gurte praktisch unbrauchbar macht.From US-A-3,277,543 a clamping device has become known which is formed from a holding part and a clamping part and has a crosspiece on which the free end of the belt can be folded down. A clamping in the sense of the present invention, however, does not take place with this crossbar and the associated web of the holding part. In the working position, i.e. the clamping position, there is a clear distance between the web and the holding part. The free, not enclosed by the belt end of the clamping part with the belt pulled through the opening rests on the surface of the belt end and is accordingly not movable downwards in this tensioning position, so that even with a further tensioning option, that is, a further tightening of the Belting, there is always a distance between the web and the holding part. The result is that the belt is held at all points of contact with the clamping part and the holding part and the overlying loop of the belt only under static friction, which can change into sliding friction relatively quickly depending on the design of such belts. In particular, the rough everyday operation when using such belts must be taken into account here, in which belt or belt surfaces frequently affected by lubricating greases and the like cannot be excluded. Belt surfaces of this type are particularly popular when moving and tensioning steel parts, which often have a corrosion protection film or surface residues caused by the production extremely short time also covered with a lubricating film, which accelerates the aforementioned sliding friction accordingly and makes such belts practically unusable.

Die bekannte Klemmeinrichtung weist ferner an dem Klemm­teil eine Abwinkelung als Kante auf, die bei geschlos­sener position die gesamten Bauteile der Klemmeinrichtung überragt, also als äußere Begrenzung eine metallische Anschlagfläche aufweist, die gemäß der vorliegenden Erfindung ausgeschaltet werden soll. Darüber hinaus ist ein Nachteil der bekannten Klemmeinrichtung in der spitz­winkligen Anlage beider Teile (Halteteil und Klemmteil) im Bereich des festen Gurtendes zu sehen. Sobald durch Ziehen an der Schlaufe ein Öffnen der Klemmeinrichtung bewirkt werden soll, gleitet die vordere Stirnseite des Klemmteils an der Oberfläche des Halteteils ab und trifft ungehindert auf den Innenmantel bzw. die Ober­fläche des Gurtendes. Hierbei verlagern sich die zur Öffnung erforderlichen Abstützkräfte direkt auf die Oberfläche des Gurtendes. Dieses führt in relativ kurzer Zeit zu entsprechenden Beschädigungen des Gurtes, so daß dieser unbrauchbar wird.The known clamping device also has an angled edge on the clamping part, which projects beyond the entire components of the clamping device in the closed position, that is to say has a metallic stop surface as an outer boundary, which is to be switched off according to the present invention. In addition, a disadvantage of the known clamping device can be seen in the acute-angled contact of both parts (holding part and clamping part) in the area of the fixed belt end. As soon as the clamping device is to be opened by pulling on the loop, the front end of the clamping part slides off the surface of the holding part and hits the inner jacket or the surface of the belt end unhindered. The supporting forces required for opening are shifted directly onto the surface of the belt end. This leads to corresponding damage to the belt in a relatively short time, so that it becomes unusable.

Die Erfindung hat sich nun die Aufgabe gestellt, hier eine besonders flach bauende Klemmeinrichtung auszu­bilden, die vorzugsweise mindestens auf der festen Klemmseite und in einem weiteren Bereich als äußere Begrenzung den Gurt selbst aufweist und damit eine metal­lische Beschädigungsfläche ausschließt.The invention has now set itself the task of forming a particularly flat-shaped clamping device, which preferably has the belt itself at least on the fixed clamping side and in a further region as an outer boundary and thus excludes a metallic damage surface.

Zur Lösung dieser Aufgabe wird bei einer Klemmeinrich­tung der eingangs genannten Art vorgeschlagen, daß Halteteil und Klemmteil als lose aufeinander verschieb­bare Rahmen mit Querstegen ausgebildet sind und das feste Gurtende beide Rahmen umfaßt, wobei der vom festen Gurtende umschlossene Quersteg des Klemmteiles breiter als der Quersteg des Halteteils ausgebildet und diesem ersten Quersteg des Klemmteils ein zweiter Quersteg als eigentlicher Klemmsteg zugeordnet ist, welcher mit seiner Stirnseite zu dem Quersteg des Halteteils auf Abstand angeordnet und dieser Abstand geringer als der entgegen der Zugrichtung verbleibende Überstand des umschlossenen ersten Quersteges ausgelegt ist.To solve this problem, it is proposed in a clamping device of the type mentioned that the holding part and the clamping part are designed as loosely slidable frames with crossbars and the fixed belt end comprises both frames, the transverse web of the clamping part enclosed by the fixed belt end being wider than the crossbar of the holding part formed and this first transverse web of the clamping part is assigned a second transverse web as the actual clamping web, which is arranged at a distance from its end face to the transverse web of the holding part and this distance is designed to be less than the protrusion of the enclosed first transverse web remaining against the pulling direction.

Ferner wird vorgeschlagen, daß der Halteteil an seinem freien, nicht vom Gurt umschlossenen Ende mit einer Zug­einrichtung ausgestattet ist.It is also proposed that the holding part is equipped with a pulling device at its free end, which is not enclosed by the belt.

Weitere Merkmale der Erfindung ergehen aus der Be­schreibung und den verbleibenden Unteransprüchen.Further features of the invention emerge from the description and the remaining subclaims.

Mit der erfindungsgemäß vorgeschlagenen Ausgestaltung werden die eingangs geschilderten Probleme ausgeschaltet und eine äußerst flach bauende Klemmeinrichtung geschaf­fen, die zudem schnell lösbar und praktisch als wieder­verwendbare Spanneinrichtung eingesetzt werden kann.With the configuration proposed according to the invention, the problems described at the outset are eliminated and an extremely flat-shaped clamping device is created which, moreover, can be quickly and practically used as a reusable clamping device.

Im nachfolgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In dieser Zeichnung ist die Klemm­einrichtung vereinfacht in einer Seitenansicht darge­stellt, aus der die wesentlichen Merkmale hervorgehen.The invention is explained in more detail below with reference to an embodiment shown in the drawing. In this drawing, the clamping device is shown in simplified form in a side view, from which the essential features emerge.

Wie aus dieser Ansicht ersichtlich, besteht die Klemm­einrichtung aus einem Halteteil 1 und einem Klemmteil 2, die als lose aufeinander verschiebbare Rahmen mit Quer­stegen 3-7 ausgebildet sind. Auf der in Zeichnungsebene linken Seite umfaßt das feste Gurtende 8 beide Rahmen, so daß sie als geschlossene Einheit zur Verfügung steht. Wie aus der Zeichnung ersichtlich, ist der umschlos­sene erste Quersteg 5 des Klemmteils 2 breiter als der Quersteg 3 des Halteteils 1 ausgebildet. Dem ersten Quersteg 5 ist ein zweiter Quersteg 6 am Klemmteil 2 als eigentliche Klemmeinrichtung bzw. als eigentlicher Klemmsteg zugeordnet, welcher mit seiner Stirnseite 9 auf Abstand zur Stirnseite 10 des Quersteges 4 angeord­net ist. Dabei ist dieser Abstand im geöffneten Zustand geringer als der entgegen der Zugrichtung 11 verbleiben­de Überstand 12 zwischen dem umschlossenen Quersteg 3 des Halteteils 3 und dem ebenfalls vom Gurtende 8 um­schlossenen Quersteg 5 des Klemmteils 2.As can be seen from this view, the clamping device consists of a holding part 1 and a clamping part 2, which are designed as loosely displaceable frames with crossbars 3-7. On the left in the plane of the drawing, the fixed belt end 8 comprises both frames, so that it is available as a closed unit. As can be seen from the drawing, the enclosed first cross bar 5 of the clamping part 2 is wider than the cross bar 3 of the holding part 1. The first cross piece 5 is assigned a second cross piece 6 on the clamping part 2 as the actual clamping device or as the actual clamping piece, which is arranged with its end face 9 at a distance from the end face 10 of the cross piece 4. In the open state, this distance is less than the protrusion 12 remaining against the pulling direction 11 between the enclosed crosspiece 3 of the holding part 3 and the crosspiece 5 of the clamping part 2, likewise enclosed by the belt end 8.

Wie bereits ausgeführt, sind die Querstege 3 und 5 von dem aneinander befestigten Gurtende 8 und 18 umschlungen. Das verbleibende freie Gurtende 13 verläuft um den Quer­ steg 4 des Halteteils 1 und anschließend zwischen der Abstandfläche der Querstege 4 und 6, um schließlich unterhalb des Quersteges 6 als freies Ende außerhalb des eigentlichen Bereichs der Klemmeinrichtung als Zugende weggeführt zu werden.As already stated, the transverse webs 3 and 5 are looped around by the belt ends 8 and 18 fastened to one another. The remaining free belt end 13 runs around the cross web 4 of the holding part 1 and then between the spacing surface of the crosspieces 4 and 6, in order to be finally led away below the crosspiece 6 as a free end outside the actual area of the clamping device as a pull end.

Sobald nun eine Zugkraft auf dieses Ende ausgeführt wird, verschiebt sich das Klemmteil 2 automatisch in Rich­tung des Pfeiles 14 und verspannt das zwischen den Stirn­seiten 9 und 10 der Querstege 4 und 6 verbleibende Ende. Wie ersichtlich, wird die Verspannungskraft umso stärker, je größer die Zugeinwirkung auf die jeweiligen Enden des Gurtes wirkt. Zum schnellen Öffnen der Klemmeinrichtung kann an dem freien Ende 15 des Halteteils 1 eine Zug­einrichtung als Quersteg 7 vorgesehen sein, welche beispielsweise mit einer Lasche als Zuggurt ausgestattet ist, die bei aufeinanderliegenden, beispielsweise gestapelten Materialien zudem einen Schutz hinsichtlich der unmittelbaren Klemmteilberührung mit dem zu stapeln­den oder zu verspannenden Material bewirkt. Um ein möglichst schnelles Öffnen mittels der Zugeinrichtung zu bewirken, weist der umschlossene Quersteg 5 des Klemm­teils 2 auf seinem zum Halteteil 1 weisenden Ende eine Anschrägung 16 auf, die zum Abrollen des korrespondieren­den Quersteges 3 des Halteteils 1 beim Öffnungsvorgang dient. Zur besseren Verspannung sind die zueinanderwei­senden Klemmflächen 9 und 10 der Querstege 4 und 6 unter einem spitzen Winkel zur Zugrichtung 11 des Spanngurtes 13 ausgelegt.As soon as a tensile force is now exerted on this end, the clamping part 2 automatically moves in the direction of the arrow 14 and braces the end remaining between the end faces 9 and 10 of the transverse webs 4 and 6. As can be seen, the greater the tensile force acting on the respective ends of the belt, the greater the tension force. To quickly open the clamping device, a pulling device can be provided as a crosspiece 7 at the free end 15 of the holding part 1, which is equipped, for example, with a tab as a pulling strap, which, in the case of materials lying on top of one another, for example stacked, also provides protection with regard to the direct contact of the clamping part with the material to be stacked or material to be braced. In order to achieve the quickest possible opening by means of the pulling device, the enclosed cross bar 5 of the clamping part 2 has a bevel 16 on its end facing the holding part 1, which is used to unroll the corresponding cross bar 3 of the holding part 1 during the opening process. For better bracing, the mutually facing clamping surfaces 9 and 10 of the crossbars 4 and 6 are designed at an acute angle to the direction of tension 11 of the tension belt 13.
