Abstract

The second jaw (4) has an associated clamp plate (7a). This is located in an aperture in the jaw. The guide bar (2) passes through the aperture in the jaw and through an aperture in the plate. The plate is clamped against the guide-bar by a spring element. It is movable against the element, to release it from the bar. The jaw can only be moved when the clamp plate is released, and can then be locked in place. A second clamp plate (7b) is also located in the aperture in the jaw, and engages on the first plate. A lever pivots the clamp plates against the spring element. <IMAGE>

Description

Die Erfindung betrifft eine Zwinge, insbesondere Schraubzwinge, mit einem an einer Führungsstange starr befestigten ersten Backen und einem auf der Führungsstange verschiebbar geführten, ein bewegliches Spannelement tragenden zweiten Backen, der von der Führungsstange in einer Durchbrechung durchsetzt ist.The invention relates to a clamp, in particular a screw clamp, with a first jaw rigidly fastened to a guide rod and a second jaw movably guided on the guide rod and carrying a movable clamping element and penetrated by the guide rod in an opening.

Bei derartigen bekannten Zwingen besteht das Problem, daß inbesondere dann, wenn der zu spannende Gegenstand eine im wesentlichen senkrechte Anbringung der Zwinge erfordert, der bewegliche Backen allein bei Ansetzen der Zwinge infolge der Schwerkraft entlang der Führungsstange nach unten rutscht. Dies ist gleichermaßen der Fall, wenn der zweite Backen bereits in Position geschoben ist, jedoch noch nicht an der Führungsstange verspannt ist, was beispielsweise dann der Fall ist, wenn nach Positionierung des zweiten Backens zum Verklemmen desselben an das Spannelement umgegriffen wird. Diese Probleme bereiten um so mehr Schwierigkeiten, wenn Arbeiten über Kopf durchzuführen sind.In such known clamps there is the problem that, in particular when the object to be clamped requires the clamp to be mounted essentially vertically, the movable jaws slide downward along the guide rod only when the clamp is attached due to the force of gravity. This is equally the case if the second jaw has already been pushed into position, but is not yet clamped to the guide rod, which is the case, for example, if after positioning the second jaw the clamp is gripped to clamp the clamping element. These problems are all the more difficult when work has to be carried out overhead.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Zwinge zu schaffen, bei welcher ein unbeabsichtigtes Verrutschen des beweglichen Backens bei jeder Handhabungsweise der Zwinge unterbunden ist.The invention is therefore based on the object of creating a clamp in which inadvertent slipping of the movable jaw is prevented with every handling of the clamp.

Zur Lösung dieser Aufgabe ist bei einer Zwinge mit den eingangs genannten Merkmalen erfindungsgemäß vorgesehen, daß dem zweiten Backen eine in einer von der Führungsstange durchsetzten Ausnehmung des Backens angeordnete Klemmplatte zugeordnet ist, die von der Führungsstange in einer Plattendurchbrechung durchsetzt ist und die mittels eines Federelementes an der Führungsstange verklemmbar und gegen das Federelement, die Verklemmung lösend, beweglich ist, so daß der nur bei gelöster Klemmplatte verschiebbare Backen in der jeweiligen Stellung arretierbar ist.To solve this problem it is provided according to the invention in a clamp with the features mentioned at the outset that the second jaw is assigned a clamping plate arranged in a recess in the jaw which is penetrated by the guide rod and which is penetrated by the guide rod in a plate opening and which is by means of a spring element clampable on the guide rod and movable against the spring element, releasing the jamming, so that the jaws, which can only be moved when the clamping plate is released, can be locked in the respective position.

Durch diese erfindungsgemäße Arretierbarkeit des zweiten Backens mittels der Klemmplatte ist es somit vorteilhaft gewährleistet, daß der zweite Backen stets in seiner jeweiligen Momentanstellung bleibt, ein unbeabsichtigtes Verrutschen ist nicht mehr möglich. Dies gilt sowohl beim Ansetzen der Zwinge als auch nach Positionierung des zweiten Backens, so daß insbesondere Arbeiten über Kopf, die bisher nur äußerst umständlich durchzuführen waren, einfachst bewerkstelligt werden können. Darüber hinaus läßt sich, da der zweite Backen optimal positionierbar ist, dieser bereits bei der Positionierung mit leichtem Andruck des Spannelementes an den zu spannenden Gegenstand anlegen, so daß vorteilhaft nur eine minimale Verspannbewegung des Spannelementes zur Erzielung einer ausreichenden Kraft erforderlich ist.This lockability of the second jaw according to the invention by means of the clamping plate thus advantageously ensures that the second jaw always remains in its respective instantaneous position, and unintentional slipping is no longer possible. This applies both when attaching the clamp and after positioning the second jaw, so that, in particular, overhead work, which previously had to be carried out only with great difficulty, can be carried out very simply. In addition, since the second jaw can be optimally positioned, it can already be placed on the object to be clamped with slight pressure when the clamping element is positioned, so that advantageously only a minimal clamping movement of the clamping element is required to achieve a sufficient force.

Um eine sichere Verklemmung und damit Arretierung des zweiten Backens auf der Führungsstange gewährleisten zu können, kann in weiterer Ausgestaltung der Erfindung ferner vorgesehen sein, daß der Klemmplatte eine ebenfalls in der Ausnehmung angeordnete zweite Klemmplatte direkt anliegend nachgeschaltet ist. Durch diese zweite Klemmplatte, die wie die erste ausgebildet ist, läßt sich somit vorteilhaft die doppelte Klemmwirkung erzielen, da der zweite Backen durch die beiden Klemmplatten an mehreren Punkten an der Führungsstange verklemmt wird, was insbesondere bei großdimensionierten Zwingen mit entsprechend schwerem zweitem Backen vorteilhaft ist. Darüber hinaus können die beim Positionieren bereits von Hand aufgebrachten Klemmkräfte noch weiter erhöht werden.In order to be able to ensure a secure jamming and thus locking of the second jaw on the guide rod, it can further be provided in a further embodiment of the invention that the clamping plate is followed by a second clamping plate also arranged in the recess. This second clamping plate, which is designed like the first, can thus advantageously achieve the double clamping effect, since the second jaw is clamped at several points on the guide rod by the two clamping plates, which is particularly advantageous in the case of large-sized clamps with a correspondingly heavy second jaw . In addition, when positioning Clamping forces already applied by hand can be increased even further.

Um eine einfache Lösung der Verklemmung zwecks Verschieben des zweiten Backens in oder aus der Klemmposition zu gewährleisten, kann im Rahmen der Erfindung ferner vorgesehen sein, daß in Verlängerung der Klemmplatte und ggf. der zweiten Klemmplatte ein Hebel zum Verschwenken der Klemmplatte gegen das Federelement angeordnet ist. Als Federelement kann erfindungsgemäß eine Feder, insbesondere eine Drahtfeder, eingesetzt werden, alternativ dazu kann das Federelement auch aus Gummi sein.In order to ensure a simple solution to the jamming for the purpose of moving the second jaw into or out of the clamping position, it can further be provided within the scope of the invention that a lever for pivoting the clamping plate against the spring element is arranged in the extension of the clamping plate and possibly the second clamping plate . According to the invention, a spring, in particular a wire spring, can be used as the spring element; alternatively, the spring element can also be made of rubber.

Zur Erhöhung der Funktionalität der Zwinge kann im Rahmen der Erfindung ferner vorgesehen sein, daß der an der Führungsstange starr befestigte Backen lösbar angeordnet ist und in beiden endständigen Positionen an der Führungsstange anbringbar ist, wodurch die Zwinge auch als Spreizwerkzeug verwendbar ist.To increase the functionality of the clamp can also be provided in the context of the invention that the jaw rigidly attached to the guide rod is detachably arranged and can be attached to the guide rod in both end positions, whereby the clamp can also be used as an expanding tool.

Fig. 1 zeigt eine Zwinge 1, bestehend aus einer Führungsstange 2, an deren oberem Ende ein starrer, erster Backen 3 angeordnet ist. Auf der Führungsstange 2 ist ein zweiter, beweglicher Backen 4 verschiebbar geführt. Der Backen 4 trägt ein Spannelement 5, im gezeigten Beispiel eine Griffspindel, jedoch können gleichermaßen andere Spannelemente, wie beispielsweise ein Exzenterspanner, angeordnet sein. In einer Ausnehmung 6 des Backens 4 (vgl. Fig. 2) sind zwei Klemmplatten 7a und 7b angeordnet, wobei die erfindungsgemäße Wirkungsweise der Zwinge auch mittels lediglich einer Klemmplatte realisierbar ist. Die Klemmplatten 7a, 7b sind von der Führungsstange in entsprechend bemessenen Durchbrechungen 8a, 8b durchsetzt, die mit einer am zweiten Backen 4 ausgebildeten, von der Führungsstange 2 durchsetzten Durchbrechung 9 fluchten.1 shows a clamp 1 consisting of a guide rod 2, at the upper end of which a rigid, first jaw 3 is arranged. On the guide rod 2, a second, movable jaw 4 is slidably guided. The jaw 4 carries a clamping element 5, in the example shown a grip spindle, but other clamping elements, such as an eccentric clamp, can be arranged in the same way. Two clamping plates 7a and 7b are arranged in a recess 6 of the jaw 4 (cf. FIG. 2), the mode of operation of the clamp according to the invention also being able to be implemented by means of only one clamping plate. The clamping plates 7a, 7b are penetrated by the guide rod in correspondingly dimensioned openings 8a, 8b which are aligned with an opening 9 formed on the second jaw 4 and penetrated by the guide rod 2.

Fig. 2 zeigt die Stellung der Klemmplatten 7a, 7b in ihrer den Backen 4 arretierenden Klemmstellung. Dabei werden die Klemmplatten 7a, 7b von einem Federelement 10, im gezeigten Beispiel einer Drahtfeder, die von der Führungsstange 2 durchsetzt ist, und die derart angeordnet ist, daß ihre Federkraft nur einseitig an den Klemmplatten 7a, 7b angreift, derart verklemmt und in Anlage an einen am Backen 4 ausgebildeten Schrägabschnitt 11 angelegt, daß die Durchbrechungsränder 12a, 12b der Durchbrechungen 8a, 8b an der Führungsstange 2 verklemmt werden. Durch diese Verklemmung kann der Backen 4 nicht entlang der Führungsstange 2 verschoben werden, sondern wird in seiner jeweiligen Stellung arretiert.Fig. 2 shows the position of the clamping plates 7a, 7b in their clamping position locking the jaws 4. Here, the clamping plates 7a, 7b by a spring element 10, in the example shown a wire spring, which is penetrated by the guide rod 2, and which is arranged such that its spring force acts only on one side on the clamping plates 7a, 7b, so clamped and in contact applied to an inclined portion 11 formed on the jaw 4 such that the opening edges 12a, 12b of the openings 8a, 8b are clamped on the guide rod 2. Because of this jamming, the jaw 4 cannot be moved along the guide rod 2, but is locked in its respective position.

Soll nun die Verklemmung zwecks Verschieben des Backens 4 in oder aus seiner Klemmposition gelöst werden, so werden die Klemmplatten 7a, 7b mittels der an ihnen ausgebildeten Hebel 13a, 13b um einen Auflagerpunkt am Schrägabschnitt 11 durch Verschwenken der Hebel 13a, 13b in Richtung des Pfeiles A aus ihrer Klemmstellung (Fig. 2) in Richtung des Pfeiles B verschwenkt. Nach Verschwenken der Klemmplatten 7a, 7b nehmen diese die in Fig. 3 gezeigte Stellung ein, in welcher die Durchbrechungsränder 12a, 12b aus ihrer Verklemmung an der Führungsstange 2 gelöst sind, so daß der Backen 4 auf der Führungsstange 2 verschiebbar ist (Pfeil C. Mit der Lösung der Klemmplatten 7a, 7b geht eine leichte Verschiebung der Klemmplatte 7a bezüglich der Klemmplatte 7b einher. Nach Positionieren des zweiten Backens 4 wird die Verschwenkung der Klemmplatten 7a, 7b wieder gelöst, so daß diese durch die komprimierte Feder 10 um den Anlagepunkt am Schrägabschnitt 11 wieder in die in Fig. 2 gezeigte Klemmstellung verschwenkt werden.If the jamming for the purpose of moving the jaw 4 into or out of its clamping position is to be released, the clamping plates 7a, 7b are moved by means of the levers 13a, 13b formed on them around a support point on the inclined section 11 by pivoting the levers 13a, 13b in the direction of the arrow A from its clamping position (Fig. 2) in the direction of Arrow B pivoted. After pivoting the clamping plates 7a, 7b, they assume the position shown in FIG. 3, in which the perforated edges 12a, 12b are released from their jamming on the guide rod 2, so that the jaw 4 can be displaced on the guide rod 2 (arrow C. The release of the clamping plates 7a, 7b is accompanied by a slight displacement of the clamping plate 7a with respect to the clamping plate 7b. After positioning the second jaw 4, the pivoting of the clamping plates 7a, 7b is released again, so that the compressed spring 10 on the contact point on the Inclined portion 11 can be pivoted back into the clamping position shown in Fig. 2.

Ferner ist Fig. 1 die lösbare Befestigung des Backens 3 an der Führungsstange 2 zu entnehmen. Dieser ist mittels einer Schraube 14, die in einer nicht sichtbaren Gewindebohrung am Stangenende eingreift, fest verschraubt. Der Backen kann aber je nach Bedarf aus der in Fig. 1 gezeigten Anordnung gelöst und mittels der Schraube 14 in einer am anderen Stangenende angebrachten Gewindebohrung 15 in um 180° gedrehter Stellung - d.h. die ebene Backenfläche 16 weist in die entgegengesetzte Richtung - befestigt werden, was die Verwendung der Zwinge als Spreizwerkzeug ermöglicht.1 shows the releasable fastening of the jaw 3 to the guide rod 2. This is firmly screwed by means of a screw 14, which engages in a non-visible threaded hole at the end of the rod. The jaw can, however, be detached from the arrangement shown in FIG. 1 as required and by means of the screw 14 in a threaded bore 15 provided on the other rod end in a position rotated by 180 ° - i.e. the flat jaw surface 16 faces in the opposite direction - to be fastened, which enables the use of the clamp as an expanding tool.
