Abstract

A bar clamp has a straight and stiff metal bar having an straight inner face, a straight and stiff fixed metal arm extending from an end of the bar and having a straight inner face substantially perpendicular to the bar inner face, and a metal corner unitarily formed with the bar and arm and joining the bar to the arm. A longitudinally facing abutment pad is carried on an outer end of the fixed arm. The corner has a circularly arcuate inner face joining the bar and arm inner faces, offset outward from planes lying on the bar and arm inner faces, and having a center of curvature substantially at a point where the planes meet. A movable arm can slide longitudinally along the bar and carries a tightening mechanism in turn carrying an abutment confronting the fixed-arm abutment and longitudinally displaceable relative to the movable arm toward and away from the fixed-arm abutment.

Description

Die Erfindung betrifft eine Spannzwinge wie Schraub- oder Hebelzwinge mit den Merkmalen des Oberbegriffs des Anpsruchs 1.The invention relates to a clamp such as screw or Lever clamp with the features of the preamble of claim 1.

Spannzwingen dieser Art sind in zahlreichen Ausführungen der Praxis, z.B. aus der DE 197 48 130 A1, bekannt. Die Erfindung betrifft Spannzwingen, bei denen die Schiene, längs der der den Spannmechanismus tragende Gleitbügel gleitverstellbar ist, und der etwa rechtwinklig zur Schiene angeordnete Festbügel mit Druckplatte einstückig, z.B. aus einem Ganzstahl-Profil geformt sind. Durch Umbiegen oder Umlenken eines Schienenabschnitts relativ zum Festbügel ist ein Bogen oder Knie mit einem relativ engen Umlenkradius ausgebildet. Was den Spannmechanismus betrifft, besteht dieser aus einer Schraubspindel oder einem Exzenter- bzw. Ratschenmechanismus mit einer Gegen-Druckplatte.Clamps of this type are available in numerous designs Practice, e.g. known from DE 197 48 130 A1. The invention relates Clamps in which the rail, along that of the Clamping mechanism carrying slide bracket is adjustable, and the fixed bracket with pressure plate arranged approximately at right angles to the rail in one piece, e.g. are formed from an all-steel profile. By Bending or redirecting a rail section relative to Fixed arm is a bow or knee with a relatively tight Deflection radius formed. As for the tensioning mechanism it consists of a screw spindle or an eccentric or Ratchet mechanism with a counter pressure plate.

Ein wesentlicher Vorteil der einstückig-stoffschlüssigen Ausbildung von Schiene und Festbügel z.B. aus kaltgezogenem Profilstahl besteht vornehmlich in einer Verringerung des Fertigungsaufwandes gegenüber einer mehrteiligen Gestaltung. Das Knie mit seinem engen Umlenkradius ist jedoch aufgrund der beim Spannen von Werkstücken auftretenden Hebelkräfte großen Belastungen ausgesetzt. So besteht insbesondere nach längerem Gebrauch unter großen Spannkräften die Gefahr von durch Kerbspannungen hervorgerufenen Spannungsrissen.A major advantage of the one-piece, cohesive Formation of rails and fixed brackets e.g. from cold drawn Profile steel consists primarily in a reduction in Manufacturing effort compared to a multi-part design. The Knee with its narrow turning radius is due to the Large clamping of workpieces occurring leverage Exposed to stress. So especially after a long time Use under high tension forces the risk of through Notch stresses caused stress cracks.

Aufgrund der Umlenkung im Kniebereich ist der Winkel relativ elastisch, so dass - will man die Elastizität auch bei großen Spannkräften begrenzen - man den Querschnitt des Stahlprofils entsprechend groß dimensionieren muß. Due to the deflection in the knee area, the angle is relative elastic so that - if you want elasticity even with large ones Limit clamping forces - one the cross section of the steel profile must be dimensioned accordingly large.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Spannzwinge der als bekannt vorausgesetzten Art gemäß DE 197 48 130 A1 zu verbessern.Proceeding from this, the object of the invention is a clamp of the type known as known DE 197 48 130 A1 to improve.

Die Erfindung löst diese Aufgabe mit den Merkmalen des Anspruchs 1, insbesondere denen des Kennzeichenteils, also dadurch, dass das Knie eine Überhöhung aufweist, an die sich, zum freien Ende von Schiene und Festbügel hin, jeweils eine entgegen der Soll-Umlenkrichtung orientierte Gegenumlenkung anschließt, die den betreffenden Profilschenkel (Schiene und Festbügel) in seine Solllage zurückführt, wobei das Knie im wesentlichen in Richtung der Winkelhalbierenden der Profilschenkel nach außen ausgeformt ist.The invention solves this problem with the features of Claim 1, in particular those of the identification part, that is in that the knee has an elevation against which, for free end of rail and fixed bracket, one against each Target deflection-oriented counter-deflection connects the relevant profile leg (rail and fixed bracket) in its target position leads back, with the knee essentially in the direction of the Bisecting the profile leg is formed outwards.

Mit den Mitteln der Erfindung wird eine besondere Gestaltung des Kniebereichs erreicht, die sich insbesondere dadurch auszeichnet, dass das Knie weiter geschwungen ausgeführt ist, der Krümmungsradius der Kniekehle also relativ groß wird. Dadurch ist der Kniebereich höher belastbar bzw. es kann zur Beherrschung vergleichbarer Spannkräfte der Profilquerschnitt verringert werden und dadurch auch der Materialeinsatz verringert werden.With the means of the invention a special design of the knee area, which is particularly characterized by that the knee is still swinging, the Radius of curvature of the hollow of the knee becomes relatively large. This is the The knee area is more resilient or it can be mastered comparable clamping forces of the profile cross section can be reduced and this also reduces the use of materials.

Mit der Erfindung geht ein weiterer erheblicher Vorteil einher, der darin besteht, dass aufgrund der Knie-Überhöhung an der Innenseite des Winkels zwischen Schiene und Festbügel ein sich in einer Hinterschneidung ausdrückender Freiraum geschaffen wird, der es gestattet, die Spannzwinge so weit auf ein Werkstück zu schieben, dass seine Flächen sowohl an der Schiene als auch am Festbügel anliegen können. Mit anderen Worten: Der Freiraum schafft Platz für eine Werkstückkante oder -ecke. Beim Stand der Technik wird dieses vergleichsweise unvollkommen dadurch angestrebt, dass die Druckplatte gegenüber dem Festbügel nach innen hin vorsteht. Dies ist bei der erfindungsgemäßen Spannzwinge nicht erforderlich. Another significant advantage is associated with the invention, which is that due to the knee elevation on the Inside of the angle between the rail and the fixed bracket creating an undercutting space that allows the clamp to be pushed onto a workpiece so far that its surfaces on both the rail and the fixed bracket can concern. In other words: the free space creates space for a workpiece edge or corner. In the prior art, this is comparatively imperfect that the Pressure plate protrudes inwards from the fixed bracket. This is not required in the clamp according to the invention.

Eine nicht gattungsgemäße Spannzwinge ist aus der DE 42 36 049 A1 bekannt. Schiene und Festbügel sind hier über ein gebogenes Knie miteinander verbunden, stehen jedoch nicht im wesentlichen unter einem rechten Winkel zueinander. Hieraus ist bereits eine Überhöhung des Knies bekannt, wobei diese jedoch nicht im wesentlichen in Richtung der Winkelhalbierenden der Profilschenkel nach außen ausgeformt ist.A non-generic clamp is from the DE 42 36 049 A1 known. The rail and fixed bracket are over one here bent knee joined together, but are not in the essentially at right angles to each other. From this is a knee elevation is already known, but this is not essentially in the direction of the bisector of the profile legs is shaped outwards.

Eine weitere nicht gattungsgemäße Spannzwinge ist aus der US 4 336 927 bekannt. Es handelt sich hierbei um eine Schnellspannzwinge, die mittels eines separaten, von der Spannzwinge lösbaren Spannelements betätigbar ist. Hier ist kein Gleitbügel vorgesehen, der einen Spannmechanismus trägt, sondern lediglich ein Schenkel, an dem ein Druckelement anliegt, wobei der Spannmechanismus nach Art einer Spannzange ein separates, von der Spannzwinge lösbares Element ist, welches nicht von dem Gleitbügel getragen wird. Bei dieser Schnellspannzwinge ist eine Überhöhung eines Knies vorgesehen, die der Aufnahme eines Betätigungszapfens der Spannzange zur Abstützung an der Spannzwinge dient.Another non-generic clamp is from the US 4,336,927. It is a Quick clamp, which uses a separate, from the Clamp releasable clamping element is actuated. There is no one here Sliding bracket provided that carries a tensioning mechanism, but only one leg on which a pressure element rests, the Clamping mechanism like a collet, a separate, from the clamp is detachable element, which is not of the Slide bracket is worn. This quick release clamp is one Elevation of a knee provided for the inclusion of a Actuating pin of the collet for support on the Clamp serves.

a clamp clamped on the back of her knee in the design corresponding to FIGS. 1 and 2.

Eine insgesamt mit 10 bezeichnete Spannzwinge umfaßt zunächst eine Schiene 11 und einen Festbügel 12. Schiene 11 und Festbügel 12 sind einstückig-stoffschlüssig miteinander verbunden; sie bestehen aus einem umgebogenen Abschnitt eines Walzprofils bzw. gekrümmten Abschnitt eines Schmiedeprofils. Beim Ausführungsbeispiel weist das Profil einen Doppel-T-Querschnitt auf. Der Bereich der Umlenkung wird im Rahmen dieser Anmeldung als Knie 13 bezeichnet, dessen Innenseite als Kniekehle 14.Includes a clamp designated as a whole with 10 first a rail 11 and a fixed bracket 12. Rail 11 and Fixed brackets 12 are integrally connected to one another; she consist of a bent section of a rolled section or curved section of a forged profile. At the In the exemplary embodiment, the profile has a double-T cross section. The area of the redirection is within the scope of this application as Designated knee 13, the inside of which is called the hollow of the knee 14.

Entlang dem geraden Abschnitt der Schiene 11 ist auf dieser ein Gleitbügel 15 gleitverstellbar angeordnet. An seinem freien Ende lagert dieser schraubverstellbar eine Gewindespindel 16 mit einer Betätigungshandhabe 17 und einer Druckplatte 18, die einer Druckplatte 19 am Ende des Festbügels 12 gegenüber steht.Along the straight section of the rail 11 is on this a slide bracket 15 is slidably arranged. At its free end this screw-adjustable supports a threaded spindle 16 with a Actuating handle 17 and a pressure plate 18, the one Pressure plate 19 faces at the end of the fixed bracket 12.

Eine erfindungsgemäße Besonderheit besteht darin, dass das Knie 13 jeweils eine Überhöhung 20 bzw. 21 aufweist, an die sich, zum freien Ende von Schiene 11 und Festbügel 12 hin, wenigstens eine entgegen der Soll-Umlenkrichtung orientierte Gegenumlenkung 22 bzw. 23 anschließt, die den betreffenden Profilschenkel (Schiene 11 und Festbügel 12) in seine Solllage zurückführt.A special feature of the invention is that Knee 13 each has an elevation 20 or 21, to which towards the free end of rail 11 and fixed bracket 12, at least a counter-deflection oriented against the target deflection direction 22 or 23 which connects the relevant profile leg (rail 11 and fixed bracket 12) returns to its target position.

Bei der Ausführungsform entsprechend den Fig. 1 bis 3 ist im Schienenbereich eine Überhöhung 21 mit nachfolgender Rückumlenkung 22 angeordnet. Daraus ergibt sich in Ansicht auf die Zeichenebene der Figuren eine etwa mit großzügig gerundeter Kniekehle 14. Deren Krümmungsradius 24 ist etwa 0,75 mal so groß wie die in derselben Ebene bzw. Richtung gemessene Werkstoffstärke 29 des Schienenprofils, die prinzipiell überall gleich ist. Die Ω-förmige Gestaltung des Knies 13 ist so ausgerichtet, dass das Knie 13 im wesentlichen in Richtung der Winkelhalbierenden der Profilschenkel 11, 12 nach außen ausgeformt ist. Die Kniekehle 14 erstreckt sich, wie aus den Fig. 1 bis 3 gut zu erkennen ist, einschließlich der kleinen rückführenden Endbögen über einen Winkelbereich von 270°.In the embodiment according to FIGS. 1 to 3 is in Rail area an elevation 21 with subsequent Return deflection 22 arranged. This results in a view of the The drawing level of the figures is roughly rounded The hollow of the knee 14. Its radius of curvature 24 is approximately 0.75 times as large as the material thickness measured in the same plane or direction 29 of the rail profile, which is basically the same everywhere. The Ω-shaped Design of the knee 13 is oriented so that the knee 13 in essentially in the direction of the bisector of the profile legs 11, 12 is formed on the outside. The hollow of the knee 14 extends as 1 to 3 can be clearly seen, including the small ones returning end bends over an angular range of 270 °.

Infolge des überhöhten Knies 13 schließen bei beiden Ausführungen Schiene 11 und Festbügel 12 über einen Bogen mit großem Krümmungsradius aneinander an. Dadurch verhält sich die Spannzwinge resistenter gegen einen Übergang vom elastischen Verhalten in den Bereich der Kaltverformung, die ein Nachlassen der Spannkräfte zur Folge haben würde. Anders ausgedrückt ist die erfindungsgemäße Spannzwinge höher belastbar, bevor die Gefahr einer Kaltverformung im Kniebereich eintritt.As a result of the inflated knee 13 close in both Designs rail 11 and fixed bracket 12 with an arch large radius of curvature. This is how the behaves Clamp more resistant to a transition from elastic Behavior in the area of cold deformation, which is a decrease in the Tension forces would result. In other words, it is Clamp according to the invention can withstand higher loads before the danger cold deformation occurs in the knee area.

Fig. 2 zeigt anschaulich, dass die erfindungsgemäß geschaffene und wie dargestellt ausgebildete Kniekehle 14 einen großzügigen Raum 25 schafft, in dem auch Ecken oder Kanten 26 eines Werkstücks 27 Platz finden, und zwar selbst dann, wenn sich im Kantenbereich des Werkstücks noch ein Grat befinden sollte.Fig. 2 shows clearly that the invention created and trained as shown knee 14 a creates a generous space 25 in which corners or edges 26 of a workpiece 27 find space, even if in the Edge area of the workpiece should still have a burr.

Andererseits kann die Kniekehle 14 zum Aufhängen der Spannzwinge 10 an einer in Fig. 3 angedeuteten und mit 28 bezeichneten Stange od. dgl. dienen. Zwar werden Spannzwingen üblicherweise an ihrer Kniekehle aufgehängt. Deren erfindungsgemäße Ausgestaltungen mit Hinterschneidungsraum hat jedoch den besonderen Vorteil, dass die Spannzwinge 10 nicht so leicht von ihrer Aufhängung 28 fallen kann, wenn sie beispielsweise einen Stoß gegen das freie Ende ihres Festbügels erfährt.On the other hand, the hollow of the knee 14 can be used to hang the Clamping clamp 10 on one indicated in FIG. 3 and with 28 designated rod or the like. Serve. There are clamps usually hung from the back of her knee. Their has inventive configurations with undercut space however, the particular advantage that the clamp 10 is not so can easily fall from its suspension 28 if, for example is knocked against the free end of its fixed bracket.
