Abstract

A rapid acting clamp, for clamping a workpiece to a workbench, has a pair of parallel operating levers topped by a handgrip and linked to a clamping element by a linkage. The clamp includes a ratchet and a spring loaded locking lever which automatically locks the ratchet in the clamp locking setting. The ratchet is released by a simple radial pull on the handgrip. This provides a single handed operation of the clamp. The ratchet arm is pivot mounted between the two operating arms with one end and is connected to the clamping element with the other end.

Description

Die Erfindung betrifft einen Schnellspanner mit einem Grundkörper und mit einer mit dem Grundkörper ei-nenends schwenkbar verbundenen Spannbacke, die durch einen mit dem Grundkörper ebenfalls schwenkbar verbundenen Spannbügel verspannbar ist, wobei der Spannbügel an seinem freien Ende einen Betätigungsgriff aufweist und zum Feststellen der Spannbacke in der Spannstellung ein Verriegelungselement vorgesehen ist.The invention relates to a quick release with a base body and with a clamping jaw which is pivotally connected to the base body and which can be clamped by a clamping bracket which is also pivotally connected to the base body, the clamping bracket having an actuating handle at its free end and for fixing the clamping jaw in the locking position a locking element is provided.

Bei bekannten Schnellspannern wird der Grundkörper an einem ersten Gegenstand befestigt. Mit der Spannbacke lässt sich entweder ein zweiter Gegenstand zwischen dem ersten Gegenstand und der Spannbacke einspannen oder ein zweiter Gegenstand gegenüber dem ersten Gegenstand verspannen. Das Spannen erfolgt mittels eines Spannbügels, der mittelbar oder unmittelbar auf die Spannbacke drückt. Der Spannbügel kann in der Spannstellung verriegelt werden. Da häufig der Spannbügel mit einer Hand bedient werden muss und der einzuspannende zweite Gegenstand mit der anderen Hand gehalten werden muss, ist das Verriegeln in der Spannstellung und das Entriegeln schwer durchzuführen.In known quick releases, the base body is attached to a first object. The clamping jaw can either clamp a second object between the first object and the clamping jaw or clamp a second object relative to the first object. The clamping is carried out by means of a clamping bracket that presses directly or indirectly onto the clamping jaw. The clamping bracket can be locked in the clamping position. Since the clamping bracket must often be operated with one hand and the second object to be clamped must be held with the other hand, locking in the clamping position and unlocking is difficult to carry out.

Aufgabe der vorliegenden Erfindung ist es, daher den eingangs genannten Schnellverschluss so weiter zu entwickeln, dass einfach Ver- und Entriegelt werden kann.The object of the present invention is therefore to develop the quick-release fastener mentioned at the outset in such a way that it can be easily locked and unlocked.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass das Verriegelungselement während des Spannvorgangs gegen eine Rückstellkraft bewegbar ist und in der Spannstellung selbsttätig eine Verriegelungsstellung einnimmt, wobei die Verriegelung durch den Betätigungsgriff, insbesondere durch axiales Betätigen des Betätigungsgriffs, lösbar ist. Durch diese Maßnahme ist der Schnellspanner einhändig bedienbar. Die Verriegelung in der Spannstellung geschieht automatisch. Zum Entriegeln muss nur der Betätigungsgriff betätigt werden. Besonders vorteilhaft ist es, wenn der Betätigungsgriff zum Entriegeln nur in axialer Richtung des Verriegelungselements bewegt werden muss.According to the invention, this object is achieved in that the locking element can be moved against a restoring force during the tensioning process and automatically assumes a locking position in the tensioning position, the locking being releasable by the actuating handle, in particular by axially actuating the actuating handle. This measure enables the quick release to be operated with one hand. The locking in the clamping position happens automatically. Only the operating handle has to be actuated to unlock. It is particularly advantageous if the actuating handle for unlocking only has to be moved in the axial direction of the locking element.

Bei einer besonders bevorzugten Ausführungsform ist ein Spannelement vorgesehen, das einenends an dem Spannbügel und anderenends an der Spannbacke schwenkbar gelagert ist. Durch diese Maßnahme lässt sich zum einen ein wirksames Spannen erreichen und zum anderen ein selbsttätiger Verriegelungsmechanismus einfach realisieren.In a particularly preferred embodiment, a clamping element is provided which is pivotably mounted on one end on the clamping bracket and on the other end on the clamping jaw. This measure enables effective clamping to be achieved on the one hand and an automatic locking mechanism to be easily implemented on the other.

Wenn das Spannelement an seinem mit dem Spannbügel schwenkbar verbundenen Ende eine Aufnahme für das Verriegelungselement aufweist, können durch Zusammenwirken des Spannteils mit dem Verriegelungselement sowohl das Spannelement als auch der Spannbügel in der Spannstellung verriegelt werden. Ein ungewolltes Öffnen des Schnellspanners wird vermieden.If the tensioning element has a receptacle for the locking element at its end pivotably connected to the tensioning bracket, both the tensioning element and the tensioning bracket can be locked in the tensioning position by the tensioning part cooperating with the locking element. Unintentional opening of the quick release is avoided.

Vorteilhafterweise ist am Spannbügel eine Gleitfläche vorgesehen, entlang der das Verriegelungselement während des Spannvorgangs in die Verriegelungsstellung gleiten kann. Durch das Gleiten entlang der Gleitfläche wird das Verriegelungselement aus seiner Rückstellposition bzw. Verriegelungsposition verfahren und in die Aufnahme des Spannelements geführt.Advantageously, a sliding surface is provided on the tensioning bracket, along which the locking element can slide into the locking position during the tensioning process. By sliding along the sliding surface, the locking element is moved out of its reset position or locking position and is guided into the receptacle of the tensioning element.

Ist das Verriegelungselement eine Verriegelungsachse, die im Spannbügel gegen eine Rückstellkraft axial beweglich gelagert ist, kann die selbsttätige Verriegelung und die Entriegelung durch Betätigen des Betätigungsgriffs in axialer Richtung der Verriegelungsachse besonders einfach realisiert werden.If the locking element is a locking axis which is axially movably mounted in the clamping bracket against a restoring force, the automatic locking and unlocking can be implemented particularly simply by actuating the actuating handle in the axial direction of the locking axis.

Wenn das Verriegelungselement einenends mit dem Betätigungsgriff verbunden ist, muss zum Entriegeln der Betätigungsgriff nur von dem Grundkörper weg bewegt werden.If the locking element is connected at one end to the actuating handle, the actuating handle only has to be moved away from the base body to unlock.

Bei einer Ausführungsform ist das Verriegelungselement an seinem freien Ende an die Aufnahme des Spannelements angepasst. Dadurch wird eine besonders sichere und spielfreie Verriegelung sicher gestellt.In one embodiment, the locking element is adapted at its free end to the receptacle of the tensioning element. This ensures a particularly secure and play-free locking.

Besonders bevorzugt ist es, wenn die Rückstellkraft durch ein Rückstellelement, wie z.B. ein Federelement erzeugt wird und das Rückstellelement sowie eine Lagerung des Verriegelungselements im Betätigungsgriff angeordnet sind. Die die selbsttätige Verriegelung bewirkenden und das einfache Entriegeln ermöglichenden Bauteile sind dadurch vor Verschmutzung und Beschädigung geschützt.It is particularly preferred if the restoring force is provided by a restoring element, e.g. a spring element is generated and the restoring element and a mounting of the locking element are arranged in the actuating handle. The components that effect the automatic locking and enable easy unlocking are thereby protected against dirt and damage.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels der Erfindung, anhand den Figuren der Zeichnung, die erfindungswesentliche Einzelheiten zeigen, und aus den Ansprüchen. Die einzelnen Merkmale können je einzeln für sich oder zu mehreren in beliebiger Kombination bei einer Variante der Erfindung verwirklicht sein.Further features and advantages of the invention result from the following description of an embodiment of the invention, with reference to the figures of the drawing, which show details essential to the invention, and from the claims. The individual characteristics can each be implemented individually or in any combination in a variant of the invention.

Fig. 1 zeigt einen Schnellspanner 1, der einen Grundkörper 2 und eine mit dem Grundkörper 2 schwenkbar verbundene Spannbacke 3 aufweist. Der Grundkörper 2 weist Durchgangslöcher 4 auf, über die er an einem nicht dargestellten Gegenstand, wie z.B. einer Werkbank, befestigbar ist. Zwischen dem nicht gezeigten Gegenstand und der Spannbacke 3 kann ein einzuspannendes Teil eingespannt werden. Am Grundkörper 2 ist ferner ein Spannbügel 5 an einem Ende um eine Schwenkachse 6 schwenkbar gelagert. Der Spannbügel 5 weist am entgegengesetzten Ende einen Betätigungsgriff 7 auf. Der Spannbügel 5 steht mit der Spannbacke 3 über ein Spannelement 8 in Verbindung, wobei das Spannelement 8 mit seinem einen Ende an der Spannbacke 3 um eine Schwenkachse 9, die zwischen den Enden der Spannbacke 3 angeordnet ist, und mit seinem anderen Ende an dem Spannbügel 5 um eine Schwenkachse 10, die zwischen den Enden des Spannbügels 5 angeordnet ist, schwenkbar gelagert ist. Das Spannelement 8 weist an seinem mit dem Spannbügel 5 schwenkbar verbundenen Ende eine gekrümmte Gleitfläche 11 auf, an der das freie Ende 12 eines als Verriegelungsachse ausgebildeten Verriegelungselements 13 während des Spannvorgangs entlang gleitet, ehe es in eine Aufnahme 14 des Spannelements 8 einrastet. Das freie Ende 12 des Verriegelungselements 13 ist dabei abgeflacht und somit an die Aufnahme 14 angepasst. Beim Spannen wird der Betätigungsgriff 7 in Pfeilrichtung 15 bewegt. Dabei wird die Klemmbacke 3 über das Spannelement 8 zwangsgeführt und bewegt sich in Richtung auf ein einzuspannendes Teil. Das Verriegelungselement 13 gleitet entlang der Gleitfläche 11 und wird dabei gegen eine Rückstellkraft axial in Richtung des Betätigungsgriffs 7 verschoben.Fig. 1 shows a quick release 1, which has a base body 2 and a jaw 3 pivotally connected to the base body 2. The base body 2 has through holes 4, via which it can be attached to an object, not shown, such as a workbench. A part to be clamped can be clamped between the object (not shown) and the clamping jaw 3. On the base body 2, a clamping bracket 5 is also pivotally mounted at one end about a pivot axis 6. The clamping bracket 5 has an operating handle 7 at the opposite end on. The clamping bracket 5 is connected to the clamping jaw 3 via a clamping element 8, the clamping element 8 having one end on the clamping jaw 3 about a pivot axis 9, which is arranged between the ends of the clamping jaw 3, and the other end on the clamping bracket 5 is pivotally mounted about a pivot axis 10, which is arranged between the ends of the clamping bracket 5. The clamping element 8 has at its end pivotally connected to the clamping bracket 5 a curved sliding surface 11, on which the free end 12 of a locking element 13 designed as a locking axis slides during the clamping process before it engages in a receptacle 14 of the clamping element 8. The free end 12 of the locking element 13 is flattened and thus adapted to the receptacle 14. When tensioning, the operating handle 7 is moved in the direction of arrow 15. The jaw 3 is positively guided over the clamping element 8 and moves in the direction of a part to be clamped. The locking element 13 slides along the sliding surface 11 and is axially displaced in the direction of the actuating handle 7 against a restoring force.

Fig. 2 zeigt den Schnellspanner 1 in seiner verriegelten Spannstellung. In der Spannstellung steht das Spannelement 8 nahezu rechtwinklig zu der Spannbacke 3 und übt die maximale Spannkraft aus. Das Verriegelungselement 13 wurde aufgrund der darauf wirkenden Rückstellkraft automatisch in die Aufnahme 14 bewegt. Dadurch steht der Spannbügel 5 in der Spannstellung fest. Der Eingriff des Verriegelungselements 13 in die Aufnahme 14 des Spannelements 8 verhindert ein Verschwenken des Spannelements um die Schwenkachsen 9, 10 und somit ein Öffnen des Schnellspanners 1. Vor dem Einrasten gleitet das Verriegelungselement 13 entlang einer ebenen Fläche 16, wodurch eine feste Verspannung sicher gestellt wird. Zum Lösen der Spannstellung muss der Verriegelungsmechanismus gelöst werden. Dazu wird der Betätigungsgriff 7 in Pfeilrichtung 17 bewegt. Das damit verbundene Verriegelungselement 13 wird dadurch aus der Aufnahme 14 gezogen und die Verriegelung aufgehoben. Der Schnellspanner kann geöffnet werden.Fig. 2 shows the quick release 1 in its locked clamping position. In the clamping position, the clamping element 8 is almost at right angles to the clamping jaw 3 and exerts the maximum clamping force. The locking element 13 was automatically moved into the receptacle 14 due to the restoring force acting thereon. As a result, the clamping bracket 5 is fixed in the clamping position. The engagement of the locking element 13 in the receptacle 14 of the tensioning element 8 prevents the tensioning element from pivoting about the pivot axes 9, 10 and thus opening of the quick release 1. Before locking, the locking element 13 slides along a flat surface 16, thereby ensuring a firm tension. The locking mechanism must be released to release the clamping position. For this purpose, the operating handle 7 is moved in the direction of arrow 17. The associated locking element 13 is thereby pulled out of the receptacle 14 and the lock is released. The quick release can be opened.

Fig. 3 zeigt eine Explosionsdarstellung des Spannbügels 5 und Betätigungsgriffs 7 des Schnellspanners, wobei den in den Figuren 1 und 2 entsprechende Teile mit gleichen Bezugsziffern bezeichnet sind. Der Spannbügel 5 weist zwei im Wesentlichen parallele Bügelarme 21, 22 auf, die über einen Steg 23 miteinander verbunden sind. Die Bügelarme 21, 22 weisen Rastnasenaufnahmen 24 auf, in die eine Führung 25 des Verriegelungselements 13 mit Rastnasen 26 einclipsbar ist. In der Führung 25 ist das Verriegelungselement 13 axial verschieblich gelagert, wobei das Verriegelungselement 13 durch ein als Schraubenfeder ausgebildetes Federelement 27 geführt ist, das sich einenends an einer mit dem Verriegelungselement 13 verbundenen Sicherungsscheibe 29 und anderenends an der Führung 25 abstützt. Das Federelement 27 übt eine Rückstellkraft auf das Verriegelungselement 13 aus und ist bestrebt, dieses in Pfeilrichtung 28 zu drücken. Die Montage des Verriegelungselements 13 in der Führung 25 erfolgt durch Eindrücken in die V-förmigen Montageführungen 30. An dem Ende 31 des Verriegelungselements 13 ist ein Verriegelungsgriff 32 befestigt, der zusammen mit der Oberschale 33 und der Unterschale 34 den Betätigungsgriff 7 darstellt. Der Verriegelungsgriff 32 kann mit seiner Halterung 35 auf das Verriegelungselement 13 aufgesteckt, aufgeschraubt oder auf andere Art und Weise befestigt sein. Die Ober- und Unterschale 33, 34 werden gegen den Verriegelungsgriff 32 gedrückt und formschlüssig an diesem gehalten. Die Ober- und Unterschale 33, 34 bilden einen Hohlraum, in dem die Führung 25, das Federelement 27 und abschnittsweise das Verriegelungselement 13 angeordnet sind. Bei Zusammengebautem Verriegelungsmechanismus können der Betätigungsgriff und das Verriegelungselement 13 relativ zu der Führung 25 und dem Spannbügel 5 in axialer Richtung des Verriegelungselements 13 entgegen der Rückstellkraft des Federelements 27 bewegt werden. Durch eine Bewegung des Betätigungsgriffs entgegen der Pfeilrichtung 28 kann also das Verriegelungselement 13 aus seiner Verriegelungsposition bewegt werden.Fig. 3 shows an exploded view of the clamping bracket 5 and actuating handle 7 of the quick release, the corresponding parts in Figures 1 and 2 are designated by the same reference numerals. The clamping bracket 5 has two substantially parallel bracket arms 21, 22, which are connected to one another via a web 23. The bracket arms 21, 22 have locking nose receptacles 24 into which a guide 25 of the locking element 13 with locking lugs 26 can be clipped. The locking element 13 is axially displaceably mounted in the guide 25, the locking element 13 being guided by a spring element 27 designed as a helical spring, which is supported at one end on a locking washer 29 connected to the locking element 13 and at the other end on the guide 25. The spring element 27 exerts a restoring force on the locking element 13 and endeavors to press it in the direction of the arrow 28. The assembly of the locking element 13 in the guide 25 is done by pressing into the V-shaped mounting guides 30. At the end 31 of the locking element 13, a locking handle 32 is attached, which together with the upper shell 33 and the lower shell 34 represents the operating handle 7. The locking handle 32 can be attached with its holder 35 to the locking element 13, screwed on or fastened in some other way. The upper and lower shells 33, 34 are pressed against the locking handle 32 and positively held on the latter. The upper and lower shells 33, 34 form a cavity in which the guide 25, the spring element 27 and, in sections, the locking element 13 are arranged. When the locking mechanism is assembled, the actuating handle and the locking element 13 can be moved relative to the guide 25 and the clamping bracket 5 in the axial direction of the locking element 13 against the restoring force of the spring element 27. The locking element 13 can thus be moved out of its locking position by moving the operating handle in the opposite direction of the arrow 28.
