Description

Die vorliegende Erfindung betrifft ein Trägerelement für eine Schraubzwinge und eine Schraubzwinge, die besser an verschiedenste Einsatzzwecke angepasst werden können und ein Werkstück zuverlässiger fixieren.The present invention relates to a support element for a screw clamp and a screw clamp, which can be better adapted to a wide variety of uses and fix a workpiece more reliably.

Es sind Schraubzwingen bekannt, die insbesondere für den Einsatz auf sogenannten Spanntischen- bzw. Schweißtischen bestimmt sind und die jeweils eine Vertikal- und Querstrebe aufweisen. Die beiden Streben sind in einem Winkel von 90° zueinander angeordnet. An einem freien Ende der Querstrebe wird eine Gewindespindel gehalten, mit der Werkstücke auf dem Schweißtisch fixierbar sind. Nachteilig ist, dass diese bekannten Schraubzwingen im Hinblick auf die Flexibilität der Verwendung und Einstellbarkeit begrenzt sind. Ferner können Drehmomente auf die bekannten Schraubzwingen wirken, die dazu führen, dass ein Werkstück nicht zuverlässig fixiert werden kann.Screw clamps are known which are intended in particular for use on so-called clamping tables or welding tables and each have a vertical and cross strut. The two struts are arranged at an angle of 90 ° to each other. A threaded spindle is held at a free end of the cross strut, with which workpieces can be fixed on the welding table. The disadvantage is that these known screw clamps are limited in terms of flexibility of use and adjustability. Furthermore, torques can act on the known screw clamps, which lead to the fact that a workpiece cannot be reliably fixed.

Die DE 10 2008 045975 A1 beschreibt eine Spannvorrichtung zur Lagerung und Fixierung eines Werkstückes auf einem Werktisch mit einer Spannsäule und mit einem Spannarm, an dem ein Spindelkopf mit einer Gewindeführung zur Führung einer Druckspindel angeordnet ist, wobei die Spannsäule und der Spannarm mittels einer Steckverbindung in Wirkverbindung stehen.The DE 10 2008 045975 A1 describes a clamping device for storing and fixing a workpiece on a work table with a clamping column and with a clamping arm, on which a spindle head with a thread guide for guiding a pressure spindle is arranged, the clamping column and the clamping arm being operatively connected by means of a plug connection.

Aus der DE 296 17 791 U1 ist ebenfalls eine Schraubzwinge bekannt, die auf Zuricht- oder Schweißtischen zum Einsatz kommt und der Fixierung eines Werkstücks auf diesen dient.From the DE 296 17 791 U1 a screw clamp is also known, which is used on dressing or welding tables and serves to fix a workpiece on it.

Es ist eine Aufgabe der vorliegenden Erfindung ein Trägerelement für eine Schraubzwinge und eine Schraubzwinge anzubieten, die flexibel auf die beabsichtigte Verwendung angepasst und eingestellt werden können und die zudem das Auftreten von unerwünschten Drehmomenten verringern.It is an object of the present invention to provide a support element for a screw clamp and a screw clamp which can be flexibly adapted and set to the intended use and which also reduce the occurrence of undesirable torques.

Die Aufgabe wird von dem Trägerelement gemäß dem unabhängigen Anspruch 1 gelöst. Weitere bevorzugte Weiterentwicklungen der Erfindung sind in den abhängigen Patentansprüchen beschrieben.The object is achieved by the carrier element according to independent claim 1. Further preferred developments of the invention are described in the dependent claims.

Es ist zu beachten, dass die Längsachse des ersten Elementes durch den Mittelpunkt des im Wesentlichen kreisförmigen oder ringförmigen Querschnittes verläuft. Die Längsachse des Aufnahmeelementes verläuft durch einen Mittelpunkt des Bereiches, in den das Befestigungsmittel eingeschoben bzw. eingesteckt wird. Die Längsachse des Befestigungsmittels, wenn dieses im Aufnahmeelement angeordnet ist, ist kongruent mit der Längsachse des Aufnahmeelementes.It should be noted that the longitudinal axis of the first element runs through the center of the essentially circular or ring-shaped cross section. The longitudinal axis of the receiving element runs through a center of the area into which the fastening means is inserted or inserted. The longitudinal axis of the fastening means, when it is arranged in the receiving element, is congruent with the longitudinal axis of the receiving element.

Der Schnittpunkt beider Längsachsen, d.h. des ersten Elementes und des Aufnahmeelementes muss nicht innerhalb der beiden Elemente positioniert sein. Konkret und bevorzugt liegt der Schnittpunkt zumindest außerhalb des ersten Elementes, so dass der Schnittpunkt auf einer gedachten Verlängerungsgeraden der Längsachse des ersten Elementes liegt.The intersection of both longitudinal axes, i.e. the first element and the receiving element need not be positioned within the two elements. Specifically and preferably, the intersection lies at least outside the first element, so that the intersection lies on an imaginary extension line of the longitudinal axis of the first element.

Im Wesentlichen ringförmig bezieht sich bei dem Aufnahmeelement bevorzugt darauf, dass ein Innenabschnitt kein Material aufweist und dieser Innenabschnitt im Wesentlichen kreisförmig ist. Die Form der Außenwand des Aufnahmeelementes muss nicht notwendigerweise kreisrund sein.In the case of the receiving element, essentially an annular shape preferably refers to the fact that an inner section has no material and this inner section is essentially circular. The shape of the outer wall of the receiving element does not necessarily have to be circular.

Geeignet zur Aufnahme des Befestigungsmittels ist das Aufnahmeelement bevorzugt dadurch, dass es ein Gewinde aufweist, in das das Befestigungsmittel oder ein Adapter eingeschraubt werden kann. Es sind aber auch Steckverbindungen oder reibschlüssige Verbindungen möglich.The receiving element is preferably suitable for receiving the fastening means in that it has a thread into which the fastening means or an adapter can be screwed. But plug connections or frictional connections are also possible.

Die Längsachse des ersten Elementes, die Längsachse des Aufnahmeelementes und die Drehachse des Aufnahmeelementes verlaufen erfindungsgemäß bevorzugt entlang eines gedachten dreidimensionalen kartesischen Koordinatensystems, wenn die beiden oben genannten Längsachsen in einem 90°-Winkel zueinander angeordnet sind.According to the invention, the longitudinal axis of the first element, the longitudinal axis of the receiving element and the axis of rotation of the receiving element preferably run along an imaginary three-dimensional Cartesian coordinate system if the two above-mentioned longitudinal axes are arranged at a 90 ° angle to one another.

Das erfindungsgemäße Trägerelement erlaubt somit, dass es insbesondere im Zusammenwirken mit einem Schweißtisch oder anderen Bauteilen, z.B. einem Winkelelement oder einem weiteren Trägerelement, flexibel eingestellt werden kann. Die Flexibilität wird insbesondere dadurch erreicht, dass das Aufnahmeelement das Befestigungsmittel dreh- bzw. schwenkbar hält, so dass insbesondere auch Werkstücke fixiert werden können, die beispielsweise gekrümmte Oberflächen aufweisen. Ferner kann das erste Element, insbesondere bei einer Verwendung in Kombination mit Schweißtischen und/oder Zubehör dafür, in eine passende Aufnahmeöffnung eingesteckt werden, so dass in Kombination mit dem Schweißtisch und/oder dem Zubehör Fixierungsanordnungen nach einem jeweiligen Anwendungszweck zusammengestellt werden können.The support element according to the invention thus allows it to be flexibly adjusted, in particular in cooperation with a welding table or other components, for example an angle element or a further support element. The flexibility is achieved in particular in that the receiving element Holds fasteners rotatable or pivotable, so that in particular workpieces can be fixed, for example, which have curved surfaces. Furthermore, the first element, in particular when used in combination with welding tables and / or accessories therefor, can be inserted into a suitable receiving opening, so that in combination with the welding table and / or the accessories, fixing arrangements can be put together according to a particular application.

Ferner ist gleichzeitig ein Vorteil des erfindungsgemäßen Trägerelementes, dass das erste Element, der Drehpunkt/Schnittpunkt und die Längsachse des Aufnahmeelementes bzw. des Befestigungsmittels in einer selben gedachten Ebene angeordnet sind. Dies bewirkt, dass die Entstehung von unerwünschten Drehmomenten reduziert bzw. verringert werden kann. Diese werden insbesondere bei bekannten Schraubzwingen erzeugt, bei denen z.B. die Längsachse eines Befestigungsmittels nicht in derselben Ebene liegt, wie die Längs- und Querstreben der bekannten Schraubzwingen.At the same time, it is also an advantage of the carrier element according to the invention that the first element, the fulcrum / intersection and the longitudinal axis of the receiving element or of the fastening means are arranged in the same imaginary plane. This means that the generation of undesired torques can be reduced or reduced. These are generated in particular with known screw clamps, in which e.g. the longitudinal axis of a fastener is not in the same plane as the longitudinal and transverse struts of the known screw clamps.

Aufgrund der kreisrunden Form des ersten Elementes wird die Einsatz-Flexibilität des ersten Trägerelementes noch weiter erhöht, da dieses, wenn es in eine gegenförmige Aufnahme eingesteckt bzw. eingeschoben ist, eine Drehbewegung um die Längsachse des ersten Elementes erlaubt. Somit bietet das erste Trägerelement zwei Drehachsen an, die die Freiheitsgrade beim Einstellen bzw. Anpassen auf ein Werkstück bzw. auf einen Einsatzzweck enorm erhöhen.Due to the circular shape of the first element, the flexibility of use of the first carrier element is increased even further, since, when it is inserted or inserted into a counter-shaped receptacle, it can rotate about the longitudinal axis of the first element. Thus, the first carrier element offers two axes of rotation, which enormously increase the degrees of freedom when adjusting or adapting to a workpiece or to an application.

Ferner kann das Halterelement zumindest zwei Schenkel aufweisen. Die beiden Schenkel sind im Wesentlichen L-förmig zueinander angeordnet. Das Aufnahmeelement ist an einer Innenwand eines der beiden Schenkel zumindest um die Drehachse herum drehbar angeordnet Der andere Schenkel ist mit einer Außenwand an einer Endfläche eines der beiden freien Enden des ersten Elementes verbunden.Furthermore, the holder element can have at least two legs. The two legs are arranged essentially L-shaped to each other. The receiving element is arranged on an inner wall of one of the two legs so that it can rotate at least around the axis of rotation. The other leg is connected to an outer wall on an end face of one of the two free ends of the first element.

Die Schenkel sind bevorzugt flache Profile, deren Höhe im Wesentlichen dem Durchmesser des ersten Elementes entspricht. Bei flachen Profilen wird eine vorteilhafte Gewichtsreduktion ermöglicht, so dass das Halterelement sehr leicht und gleichzeitig mechanisch fest und steif ausgeführt ist.The legs are preferably flat profiles, the height of which essentially corresponds to the diameter of the first element. In the case of flat profiles, an advantageous weight reduction is made possible, so that the holder element is made very light and at the same time mechanically strong and rigid.

Besonders bevorzugt ist ein kürzerer Schenkel vorgesehen, dessen Außenseite mit der Endfläche des ersten Elementes planflächig und fest verbunden ist. Dazu eignen sich besonders eine Schweiß- oder Lötverbindung, wenn die einzelnen Elemente metallisch sind, eine Klebeverbindung, bevorzugt bei Kunststoffelementen, und/oder eine Schraubverbindung.A shorter leg is particularly preferably provided, the outside of which is connected flat and firmly to the end face of the first element. A welded or soldered connection is particularly suitable for this purpose if the individual elements are metallic, an adhesive connection, preferably in the case of plastic elements, and / or a screw connection.

Weiterhin ist bevorzugt ein zweiter, längerer Schenkel vorgesehen, der L-förmig zu dem kürzeren Schenkel angeordnet ist, wobei der längere Schenkel bevorzugt parallel zur Längsachse des ersten Elementes angeordnet ist. Die parallele Anordnung des längeren Schenkels erlaubt eine genaue Ausrichtung des Aufnahmeelementes zu dem ersten Element.Furthermore, a second, longer leg is preferably provided, which is arranged in an L-shape to the shorter leg, the longer leg preferably being arranged parallel to the longitudinal axis of the first element. The parallel arrangement of the longer leg allows the receiving element to be precisely aligned with the first element.

Die beiden Schenkel können direkt miteinander, auch einstückig, verbunden sein. Es kann jedoch auch ein Zwischenabschnitt vorgesehen sein, der z.B. einen radiusförmigen Übergang zwischen den beiden - Schenkeln ausbildet. Der Radius erhöht die Formsteifigkeit des Halterelementes zusätzlich.The two legs can be connected directly to one another, also in one piece. However, an intermediate section can also be provided, which e.g. forms a radius-shaped transition between the two legs. The radius additionally increases the stiffness of the holder element.

Der kürzere Schenkel kann an einem Ende abgerundet sein, so dass die Abrundung im Wesentlichen mit einer Außenkontur des ersten Elementes übereinstimmt. Dies ermöglicht eine optimale Gewichtsersparnis und eine kompakte, ergonomische Bauform. Zusätzlich oder alternativ kann der längere Schenkel an einem Ende abgerundet sein, so dass die Abrundung im Wesentlichen mit einer Außenkontur des ersten Elementes übereinstimmt. Dies ermöglicht eine optimale Gewichtsersparnis und eine ergonomische Bauform.The shorter leg can be rounded at one end so that the rounding essentially corresponds to an outer contour of the first element. This enables optimal weight savings and a compact, ergonomic design. Additionally or alternatively, the longer leg can be rounded at one end, so that the rounding essentially corresponds to an outer contour of the first element. This enables optimal weight savings and an ergonomic design.

Der Begriff Außenwand der Schenkel soll sich auf das Halterelement beziehen, so dass die jeweiligen Außenwände der Schenkel diejenigen sind, die auf der konvexen Seite der L-Form angeordnet sind. Die Innenwände der Schenkel liegen dann entsprechend auf der konkaven Seite. Die Wandflächen der Schenkel sind bevorzugt plan gestaltet, um eine möglichst wenig komplexe Formgebung zu ermöglichen.The term outer wall of the legs is intended to refer to the holder element, so that the respective outer walls of the legs are those which are arranged on the convex side of the L-shape. The inner walls of the legs are then correspondingly on the concave side. The wall surfaces of the legs are preferably designed to be flat in order to allow the least complex shape possible.

Das L-förmige Halterelement kann das Aufnahmeelement bevorzugt einseitig lagern. Diese einseitige Lagerung, z.B. dadurch ermöglicht, dass das Aufnahmeelement nur an dem längeren Schenkel angeordnet und dort drehbar befestigt ist, bewirkt eine weitere Materialeinsparung und somit Gewichtsreduktion gegenüber einer zweiseitigen Lagerung. Die L-Form des Halterelementes gewährleistet auch bei der einseitigen Lagerung eine mechanische Steifigkeit und Formtreue des Halterelementes.The L-shaped holder element can preferably support the receiving element on one side. This one-sided mounting, for example in that the receiving element is arranged only on the longer leg and is rotatably fastened there, brings about another Material savings and thus weight reduction compared to double-sided storage. The L-shape of the holder element ensures mechanical rigidity and shape retention of the holder element even with one-sided storage.

Diese Anordnung und Lagerung des Aufnahmeelementes ist konstruktiv vorteilhaft, da keine komplex gestalteten Halterungen vorgesehen sein müssen und gleichzeitig ermöglicht wird, dass sich die Längsachsen des Aufnahmeelementes und des ersten Elementes schneiden und sich das Aufnahmeelement möglichst ungehindert drehen kann.This arrangement and mounting of the receiving element is structurally advantageous since no complexly designed brackets have to be provided and at the same time it is made possible that the longitudinal axes of the receiving element and the first element intersect and the receiving element can rotate as freely as possible.

Ferner kann das Aufnahmeelement eine teiloffene oder geschlossene Ringform mit einem Gewinde im Bereich der Innenwand aufweisen. Das Gewinde kann derart ausgebildet sein, ein Gewinde des Befestigungsmittels aufzunehmen.Furthermore, the receiving element can have a partially open or closed ring shape with a thread in the region of the inner wall. The thread can be designed to receive a thread of the fastener.

Eine teiloffene Ringform ist beispielsweise möglich, wenn ein Teil des Ringumfanges ausgelassen ist, z.B. auf einer Breite, die dem Durchmesser eines Befestigungsmittels entspricht. Bevorzugt wird die vollständige Ringform. Diese erlaubt ein Einstecken bzw. Einführen eines Befestigungsmittels von oben oder unten. Aufgrund des Gewindes und der stabilen Ringform kann das Befestigungsmittel sicher von dem Aufnahmeelement gehalten werden. Die Länge in der Längsachse des Befestigungsmittels, die jeweils seitlich zu dem Aufnahmeelement angeordnet ist, kann aufgrund des Gewindes mittels einer Dreh- bzw. Schraubbewegung verändert bzw. eingestellt werden.A partially open ring shape is possible, for example, if part of the ring circumference is left out, e.g. on a width that corresponds to the diameter of a fastener. The complete ring shape is preferred. This allows a fastener to be inserted or inserted from above or below. Due to the thread and the stable ring shape, the fastener can be held securely by the receiving element. The length in the longitudinal axis of the fastener, which is arranged laterally to the receiving element, can be changed or set due to the thread by means of a turning or screwing movement.

Ferner kann das Aufnahmeelement an einer Außenwand zumindest eine Welle angeordnet haben, die in einer Nabe des Schenkels des Halterelementes anordenbar sein kann.Furthermore, the receiving element can have at least one shaft arranged on an outer wall, which can be arranged in a hub of the leg of the holder element.

Selbstverständlich kann die Anordnung auch umgekehrt ausgeführt sein, d.h. es ist eine Welle an dem Schenkel vorgesehen und eine Aufnahme bzw. Nabe an dem Aufnahmeelement. Die Welle-Nabe-Verbindung erlaubt die Ausbildung einer Drehachse, um die sich das Aufnahmeelement herum drehen kann. Die Verbindung kann z.B. mittels einer Schraube oder dgl. gesichert sein. Eine solche Konstruktion ist mit wenig Aufwand herstellbar, erlaubt aber eine sehr zuverlässige und präzise Funktion.Of course, the arrangement can also be reversed, i.e. there is a shaft on the leg and a receptacle or hub on the receiving element. The shaft-hub connection allows the formation of an axis of rotation about which the receiving element can rotate. The connection can e.g. be secured by means of a screw or the like. Such a construction can be produced with little effort, but allows a very reliable and precise function.

Ferner kann auch eine Schraubverbindung vorgesehen sein, die das Aufnahmeelement an dem Halterelement drehbar lagert. So kann eine plan gestaltete Fläche an der Außenwand des Aufnahmeelementes vorgesehen sein, die flächig in Kontakt mit der Innenwand des längeren Schenkels des Halterelementes steht und von einer Schraubverbindung an die Innenwand gezogen wird. Dies ist eine weitere wenig komplexe und sichere Verbindungs-/Lagerungsoption des Aufnahmeelementes.Furthermore, a screw connection can also be provided, which Receiving element rotatably mounted on the holder element. Thus, a planar surface can be provided on the outer wall of the receiving element, which is in flat contact with the inner wall of the longer leg of the holder element and is pulled by a screw connection to the inner wall. This is another less complex and secure connection / storage option of the receiving element.

Ferner kann das erste Trägerelement eine Dreheinrichtung aufweisen, die die Welle und die Nabe zur drehbaren Lagerung des Aufnahmeelementes an dem Halterelement umfassen kann und einen Kontaktabschnitt, in dem ein Abschnitt einer Außenwand des Aufnahmeelementes und ein Abschnitt einer Innenwand des Halterelementes miteinander in Kontakt stehen können, wenn das Aufnahmeelement an dem Halterelement drehbar gelagert ist.Furthermore, the first carrier element can have a rotating device which can comprise the shaft and the hub for rotatably mounting the receiving element on the holder element and a contact section in which a section of an outer wall of the receiving element and a section of an inner wall of the holder element can be in contact with one another, if the receiving element is rotatably mounted on the holder element.

Der Kontaktabschnitt ist der Abschnitt, an dem sich ein Abschnitt des Halterelementes bzw. dessen Schenkel und ein Teil des Aufnahmeelementes zumindest leicht berühren. Dieser zumindest leichte Kontakt ist Ursprung für eine Reibkraft, die ein zu leichtes bzw. selbsttätiges Verdrehen des Aufnahmeelementes verhindern kann, wenn dies erforderlich sein sollte. Weiterhin kann der Reibkontakt durch einen engeren Kontakt der beiden Abschnitte auch so eingestellt werden, dass die Verdrehung des Aufnahmeelementes mit einer vorbestimmten z.B. von Hand aufbringbaren Kraft erfolgen kann. Selbstverständlich ist dies optional: Es kann auch kein Kontaktabschnitt vorgesehen sein.The contact section is the section at which a section of the holder element or its leg and part of the receiving element touch at least slightly. This at least slight contact is the origin of a frictional force which can prevent the receiving element from being turned too easily or automatically if this should be necessary. Furthermore, the frictional contact can be adjusted by a closer contact of the two sections so that the rotation of the receiving element with a predetermined e.g. force that can be applied by hand. Of course, this is optional: there can also be no contact section.

Ferner kann der Kontaktabschnitt eine Gleitfläche darstellen. Alternativ können an dem Kontaktabschnitt Rastnuten und Vorstehungen der Innenwand des Halterelementes und der Außenwand des Aufnahmeelementes miteinander in Kontakt stehen.Furthermore, the contact section can represent a sliding surface. Alternatively, latching grooves and projections of the inner wall of the holder element and the outer wall of the receiving element can be in contact with one another on the contact section.

Diese weiteren Elemente ermöglichen, dass ein Rastmechanismus ein selbsttätiges oder zu leichtes Verdrehen des Aufnahmeelementes verhindert. Die Rastnuten und Vorstehungen können z.B. zumindest teilweise ineinandergreifen, so dass ein Bediener ein vorbestimmtes Drehmoment aufbringen muss, um eine Drehung zu bewirken. Weiter kann die Dreheinrichtung auch ein elastisches Element aufweisen, z.B. eine Feder, die axial in Richtung der Drehachse wirkt und die Vertiefungen und Vorstehungen zueinander zieht. Eine Drehung kann der Bediener dann z.B. dadurch auslösen, dass er in axialer Richtung der Drehachse an dem Aufnahmeelement, d.h. entgegen der Federkraft, zieht und gleichzeitig dieses um die Drehachse dreht. Beim Loslassen des Aufnahmeelementes zieht die Feder die Vertiefungen und Vorstehungen wieder zusammen, so dass eine weitere Drehung wieder blockiert oder erschwert wird.These further elements enable a latching mechanism to prevent the receiving element from rotating automatically or too easily. The locking grooves and projections can, for example, at least partially interlock, so that an operator must apply a predetermined torque in order to bring about a rotation. Furthermore, the rotating device can also have an elastic element, for example a spring, which acts axially in the direction of the axis of rotation and pulls the depressions and projections towards one another. The operator can then trigger a rotation, for example, by pulling on the receiving element in the axial direction of the axis of rotation, ie counter to the spring force and at the same time it rotates around the axis of rotation. When the receiving element is released, the spring pulls the depressions and projections back together, so that a further rotation is blocked again or made more difficult.

Ferner kann ein Abstand zwischen einer Innenwand des Schenkels des Halterelementes, der an dem freien Ende des ersten Elementes angeordnet sein kann, und einer Außenwand des Aufnahmeelementes zumindest gleich groß oder größer sein wie/als der Abstand zwischen dem Schnittpunkt der Längsachse des ersten Elementes mit der Längsachse des Aufnahmeelementes und einem Punkt an einer Außenkante des Aufnahmeelementes.Furthermore, a distance between an inner wall of the leg of the holder element, which can be arranged at the free end of the first element, and an outer wall of the receiving element can be at least as large or larger than / as the distance between the intersection of the longitudinal axis of the first element with the Longitudinal axis of the receiving element and a point on an outer edge of the receiving element.

Die Außenkante ist eine Kante des Aufnahmeelementes, die einen äußeren Umfang des Aufnahmeelementes und gleichzeitig eine axiale Länge dessen begrenzt. Ein Punkt auf der Außenkante sollte für eine möglichst 360° Drehbarkeit des Aufnahmeelemente ohne das Befestigungsmittel so weit von der Innenwand des gegenüberliegenden Schenkels entfernt sein wie der Abstand zum Drehpunkt des Aufnahmeelementes beträgt. Dieser Abstand kann mittels der Länge des längeren Schenkels, der das Aufnahmeelement hält, festgelegt werden. Weiterhin wird der Abstand am bevorzugtesten derart gewählt, dass ein Befestigungsmittel zumindest 90° im und gegen den Uhrzeigersinn aus einer vertikalen Position heraus verschwenkbar ist. Ist der Abstand so gewählt, dass er etwas größer als die Länge des Befestigungsmittels ist, so kann eine 360°-Drehung auch bei montiertem Befestigungsmittel erreichbar sein.The outer edge is an edge of the receiving element, which delimits an outer circumference of the receiving element and at the same time an axial length thereof. A point on the outer edge should be as far from the inner wall of the opposite leg as the distance to the pivot point of the receiving element for the 360 ° rotatability of the receiving element without the fastening means. This distance can be determined by means of the length of the longer leg that holds the receiving element. Furthermore, the distance is most preferably chosen such that a fastening means can be pivoted at least 90 ° clockwise and counterclockwise from a vertical position. If the distance is chosen so that it is somewhat larger than the length of the fastener, a 360 ° rotation can also be achieved when the fastener is installed.

Ferner kann der Radius der Außenwand des Aufnahmeelementes gleich groß oder größer sein wie/als ein Radius des ersten Elementes. Optional kann die Länge des Aufnahmeelementes mindestens so lang sein wie der Durchmesser des ersten Elementes sein. Dies ermöglicht, dass das Trägerelement möglichst kompakt baut.Furthermore, the radius of the outer wall of the receiving element can be the same size or larger than / as a radius of the first element. Optionally, the length of the receiving element can be at least as long as the diameter of the first element. This enables the carrier element to be as compact as possible.

Ferner kann das Befestigungsmittel eine Gewindespindel oder ein Schnellspanner sein. Das Befestigungsmittel kann in einem Gewindeadapter anordenbar sein, dessen Innengewinde mit einem Außengewinde des Befestigungsmittels im Wesentlichen übereinstimmen kann und dessen Außengewinde im Wesentlichen mit dem Gewinde des Aufnahmeelementes übereinstimmen kann. Gewindespindeln weisen unterschiedliche Gewindedurchmesser auf. Damit eine flexible Auswahl von Gewindespindeln, aber auch anderen Bauteilen wie einem Schnellspanner, möglich ist, können Adapterhülsen vorgesehen sein, die ein auf die Gewindespindel angepasstes Innengewinde aufweisen und ein Außengewinde, das zu dem Gewinde des Aufnahmeelementes passt. Die Adapterhülsen haben den Vorteil, dass eine sehr flexible Verwendung von unterschiedlichen Befestigungsmitteln ermöglicht wird, die mit geringem (Wechsel-)Aufwand an/in dem Aufnahmeelement montierbar sind.Furthermore, the fastening means can be a threaded spindle or a quick release. The fastening means can be arranged in a thread adapter, the internal thread of which can essentially match an external thread of the fastening means and the external thread of which can essentially match the thread of the receiving element. Threaded spindles have different thread diameters. Adapter sleeves can be used to allow a flexible selection of threaded spindles, but also other components such as a quick release be provided which have an internal thread adapted to the threaded spindle and an external thread which matches the thread of the receiving element. The adapter sleeves have the advantage that a very flexible use of different fastening means is made possible, which can be mounted on / in the receiving element with little (change) effort.

Wenn das Befestigungsmittel in dem Aufnahmeelement montiert ist, so fallen die beiden Längsachsen der beiden Teile im Wesentlichen zusammen, d.h. sie sind kongruent. Dies verhindert das Erzeugen von unerwünschten Drehmomenten, da somit das erste Element, der Drehpunkt des Aufnahmeelementes und die Längsachse des Befestigungselementes in einer selben Ebene liegen.When the fastening means is mounted in the receiving element, the two longitudinal axes of the two parts essentially coincide, i.e. they are congruent. This prevents the generation of undesired torques, since the first element, the pivot point of the receiving element and the longitudinal axis of the fastening element are in the same plane.

Eine erfindungsgemäße Schraubzwinge kann ein erstes erfindungsgemäßes Trägerelement aufweisen und ein zweites Trägerelement. Das zweite Trägerelement kann ein zweites Element haben und einen im Wesentlichen kreisförmigen Querschnitt. Das zweite Element kann zwei freie Enden haben. Ein im Wesentlichen kreisringförmiges Element kann an einem der beiden freien Enden des zweiten Elementes angeordnet sein. Das kreisringförmige Element kann dazu geeignet sein, das erste Element des ersten Trägerelementes beweglich zu lagern.A screw clamp according to the invention can have a first support element according to the invention and a second support element. The second carrier element can have a second element and a substantially circular cross section. The second element can have two free ends. A substantially circular element can be arranged on one of the two free ends of the second element. The annular element can be suitable for movably supporting the first element of the first carrier element.

Insbesondere die bewegliche Lagerung des ersten Elementes bzw. des ersten Trägerelementes in Relation zu dem zweiten Trägerelement verbessert die Anpassbarkeit der Schraubzwinge an eine große Vielzahl von Einsatzzwecken.In particular, the movable mounting of the first element or of the first carrier element in relation to the second carrier element improves the adaptability of the screw clamp to a large number of purposes.

Bevorzugt sind die Längsachsen des ersten und zweiten Elementes in einer selben Ebene angeordnet.The longitudinal axes of the first and second elements are preferably arranged in the same plane.

Ferner kann das kreisringförmige Element einen Kreisringabschnitt aufweisen, der derart ausgebildet ist, das erste Element um seine Längsachse drehbar und entlang seiner Längsachse verschiebbar zu halten. Ein Verschieben entlang der Längsachse ermöglicht, dass viele unterschiedliche Spannbereiche einstellbar sind. Die Verdrehbarkeit ermöglicht insbesondere in Kombination mit der weiteren Verdrehbarkeit des Aufnahmeelementes eine optimale Anpassung auf z.B. die Form eines zu fixierenden Bauteils.Furthermore, the annular element can have a circular ring section which is designed to hold the first element rotatable about its longitudinal axis and displaceable along its longitudinal axis. Moving along the longitudinal axis enables many different clamping ranges to be set. The rotatability enables, in particular in combination with the further rotatability of the receiving element, an optimal adaptation to, for example, the shape of a component to be fixed.

Ferner kann zwischen einem Durchmesser des Kreisringabschnittes und einem Durchmesser des ersten Elementes eine vorbestimmte Spiel- oder Übergangspassung vorgesehen sein. Bevorzugt sind dabei solche Passungen, die ein Verschieben und/oder Verdrehen des ersten Elementes in dem Kreisringabschnitt von Hand erlauben. Andere Passungen sind selbstverständlich auch möglich.Furthermore, a predetermined clearance or transition fit can be provided between a diameter of the circular ring section and a diameter of the first element. Preference is given to fits that allow the first element to be moved and / or rotated in the circular ring section by hand. Other fits are of course also possible.

Ferner kann das zweite Trägerelement das erste Trägerelement derart halten, dass die Längsachsen des ersten und zweiten Elementes in einer gemeinsamen gedachten Ebene liegen können, und ein Schnittpunkt der Längsachse des ersten Elementes mit einer Längsachse des Aufnahmeelementes in der selben gemeinsamen gedachten Ebene angeordnet sein kann. Dies ermöglicht ein weitestgehende Reduktion von Drehmomenten und somit eine sehr zuverlässige Fixierung von Werkstücken mittels der Schraubzwinge.Furthermore, the second support element can hold the first support element such that the longitudinal axes of the first and second elements can lie in a common imaginary plane, and an intersection of the longitudinal axis of the first element with a longitudinal axis of the receiving element can be arranged in the same common imaginary plane. This enables the greatest possible reduction in torque and thus a very reliable fixation of workpieces using the screw clamp.

Ferner können das erste und zweite Element jeweils im Wesentlichen den Querschnitt eines Rundrohres aufweisen und beide Elemente im Wesentlichen den gleichen Radius aufweisen. Dies ermöglicht, dass die beiden Elemente mechanisch sehr belastbar sind. Aufgrund des gleichen Radius' kann eine variable Kombination verschiedener erster und zweiter Elemente ermöglicht werden.Furthermore, the first and second elements can each have essentially the cross section of a round tube and both elements can have essentially the same radius. This enables the two elements to be mechanically very resilient. Due to the same radius, a variable combination of different first and second elements can be made possible.

Ferner kann die Länge des kreisringförmigen Elementes mindestens so lang sein wie der Durchmesser des zweiten Elementes. Dies reduziert die Baugröße der Schraubzwinge auf ein Minimum.Furthermore, the length of the annular element can be at least as long as the diameter of the second element. This reduces the size of the screw clamp to a minimum.

Zusammenfassend ermöglicht die Erfindung somit, dass das Trägerelement und die Schraubzwinge sehr flexibel angepasst werden können und u.a. auch komplex geformte Werkstücke sicher fixiert werden können.In summary, the invention thus enables the carrier element and the screw clamp to be adapted very flexibly and, inter alia, even complex shaped workpieces can be securely fixed.

Im Folgenden werden verschiedene Beispiele der vorliegenden Erfindung detailliert unter Bezugnahme auf die Figuren beschrieben. Gleiche bzw.. ähnliche Elemente in den Figuren werden hierbei mit gleichen Bezugszeichen bezeichnet. Die vorliegende Erfindung ist jedoch nicht auf die beschriebenen Ausführungsmerkmale begrenzt, sondern umfasst weiterhin Modifikationen von Merkmalen der beschriebenen Beispiele und Kombination von Merkmalen verschiedener Beispiele im Rahmen des Schutzumfangs der Ansprüche.Various examples of the present invention are described in detail below with reference to the figures. The same or similar elements in the figures are denoted by the same reference numerals. However, the present invention is not limited to the described design features, but further includes modifications of features of the described examples and combination of features of different examples within the scope of the claims.

Figur 1 zeigt das erste Trägerelement 1, das von dem Kreisringabschnitt 11a des zweiten Trägerelementes 9 gehalten wird. Konkret ist ein erstes Element 3 in ein kreisringförmiges Element 11 eingeschoben, so dass es darin drehbar und verschiebbar gehalten wird. Die Längsachse L3 des ersten Elementes 3 verläuft mittig durch das erste Element 3 und wird von der Längsachse L10 eines zweiten Elementes 10 des zweiten Trägerelementes 9, die mittig durch das zweite Element 10 verläuft, geschnitten. Das erste und zweite Element 3, 10 sind kreisrundförmig und besonders bevorzugt sind es Rundrohre. Figure 1 shows the first carrier element 1 which is held by the circular ring section 11a of the second carrier element 9. Specifically, a first element 3 is inserted into an annular element 11 so that it is rotatably and displaceably held therein. The longitudinal axis L3 of the first element 3 runs centrally through the first element 3 and is cut by the longitudinal axis L10 of a second element 10 of the second carrier element 9, which runs centrally through the second element 10. The first and second elements 3, 10 are circular in shape and particularly preferably they are round tubes.

Ein freies Ende 3a des ersten Elementes 3 ist dazu geeignet, in den Kreisringabschnitt 11a eingeführt zu werden. An dem anderen freien Ende 3b des ersten Elementes 3 ist ein Halterelement 4 befestigt. An einem freien Ende 10a des zweiten Elementes 10 ist das kreisringförmige Element 11 fest angeordnet. Dazu ist das freie Ende 10a.im Bereich einer Endfläche konkav geformt, so dass eine passgenaue Aufnahme des kreisringförmigen Elementes 11 daran ermöglicht wird.A free end 3a of the first element 3 is suitable for being inserted into the circular ring section 11a. A holder element 4 is fastened to the other free end 3b of the first element 3. The annular element 11 is fixedly arranged at a free end 10a of the second element 10. For this purpose, the free end 10a. Is concavely shaped in the region of an end face, so that the annular element 11 can be held there with a precise fit.

Das Halterelement 4 weist zwei gezeigte Schenkel 4a, 4b auf. Der kürzere gezeigte Schenkel 4a ist an einem Ende abgerundet, so dass die Abrundung im Wesentlichen mit einer Außenkontur des ersten Elementes 3 übereinstimmt. Eine Endfläche des freien Endes 3b des ersten Elementes 3 ist plan geformt, so dass eine flächige Verbindung mit einer Außenseite 4d des kürzeren Schenkels 4a bildbar ist. Der längere Schenkel 4b ist parallel zu der Längsachse L3 des ersten Elementes 3 angeordnet. Ein Übergangselement 4e verbindet die beiden Schenkel 4a, 4b im Wesentlichen radiusförmig einstückig miteinander.The holder element 4 has two legs 4a, 4b shown. The shorter leg 4a shown is rounded at one end, so that the rounding essentially corresponds to an outer contour of the first element 3. An end face of the free The end 3b of the first element 3 is shaped flat so that a flat connection with an outside 4d of the shorter leg 4a can be formed. The longer leg 4b is arranged parallel to the longitudinal axis L3 of the first element 3. A transition element 4e connects the two legs 4a, 4b to one another in a substantially radius-like manner.

Ein Aufnahmeelement 5 zur Aufnahme und zum Halten eines Befestigungselementes 6, das neben der Schraubzwinge 2 als Gewindespindel 6a gezeigt ist, ist an dem längeren Schenkel 4b einseitig gelagert angeordnet.A receiving element 5 for receiving and holding a fastening element 6, which is shown next to the screw clamp 2 as a threaded spindle 6a, is arranged on one side on the longer leg 4b.

Eine Dreheinrichtung 7 umfasst eine nicht gezeigte Welle und Nut, die ineinandergreifen, so dass das Aufnahmeelement 5 drehbar an dem Schenkel 4b gelagert ist. Ein Kontaktabschnitt 7a ist weiterhin gezeigt, an dem eine Innenwand 4c des Halterelementes 4 und eine Außenwand 5b des Aufnahmeelementes 5 bevorzugt miteinander in Kontakt stehen. Eine Innenseite 5c des Aufnahmeelementes 5, das ringförmig gezeigt ist, weist ein Gewinde auf. Das Gewinde passt zu einem Außengewinde eines Adapterelementes 8 und/oder einem nicht gezeigten Außengewinde des Befestigungsmittels 6. Eine Längsachse L5 des Aufnahmeelementes 5 verläuft mittig entlang der Ringachse. Die Längsachse L5 schneidet sich mit der gedachten Verlängerung der Längsachse L3 an einem Schnittpunkt S, den Figur 3 zeigt. Der Schnittpunkt S, die Längsachsen L3, L5 und L10 liegen alle in einer selben gedachten Ebene. Dies vermeidet das Auftreten von unerwünschten Drehmomenten beim Fixieren von Werkstücken.A rotating device 7 comprises a shaft and groove, not shown, which engage in one another, so that the receiving element 5 is rotatably mounted on the leg 4b. A contact section 7a is also shown, on which an inner wall 4c of the holder element 4 and an outer wall 5b of the receiving element 5 are preferably in contact with one another. An inner side 5c of the receiving element 5, which is shown in a ring, has a thread. The thread fits an external thread of an adapter element 8 and / or an external thread, not shown, of the fastening means 6. A longitudinal axis L5 of the receiving element 5 runs centrally along the ring axis. The longitudinal axis L5 intersects with the imaginary extension of the longitudinal axis L3 at an intersection S Figure 3 shows. The intersection S, the longitudinal axes L3, L5 and L10 all lie in the same imaginary plane. This avoids the occurrence of undesirable torques when fixing workpieces.

Figur 2 zeigt die Schraubzwinge 2, die eine Gewindespindel 6a in einer um ca. 5° entgegen dem Uhrzeigersinn verdrehten Position hält. Die Gewindespindel 6a wird bevorzugt in die Aufnahme des Aufnahmeelementes 5 eingeführt, indem ein Druckteller 12 von der Gewindespindel 6a gelöst wird, so dass eine Spitze der Gewindespindel 6a in das Aufnahmeelement 5 eingebracht werden kann. Danach kann der Druckteller 12 wieder mit der Gewindespindel 6a verbunden werden. Das Halterelement 4 kann das Befestigungsmittel 6 in einer verdrehten Position bevorzugt aufgrund der Reibkraft halten, die an dem Kontaktabschnitt 7a der Dreheinrichtung 7 vorliegt. Das erste Element 3 kann in dem kreisringförmigen Element 11 weiterhin gedreht und/oder verschoben werden. Dies erfolgt bevorzugt von Hand. Eine Spielpassung oder Übergangspassung zwischen dem ersten Element 3 und dem kreisringförmigen Element 11 kann derart eingestellt sein, dass das Verschieben und/oder Verdrehen sehr leicht von Hand möglich sein kann oder mittels Werkzeugen. Figure 2 shows the screw clamp 2, which holds a threaded spindle 6a in a position rotated counterclockwise by approximately 5 °. The threaded spindle 6a is preferably inserted into the receptacle of the receiving element 5 by loosening a pressure plate 12 from the threaded spindle 6a so that a tip of the threaded spindle 6a can be introduced into the receiving element 5. Then the pressure plate 12 can be connected again to the threaded spindle 6a. The holder element 4 can hold the fastening means 6 in a rotated position, preferably due to the frictional force that is present on the contact section 7 a of the rotating device 7. The first element 3 can continue to be rotated and / or displaced in the annular element 11. This is preferably done by hand. A clearance fit or transition fit between the first element 3 and the annular element 11 can be set in such a way that the displacement and / or rotation can be done very easily by hand or by means of tools.

Die Seitenansicht der Figur 3 zeigt eine Vertikalposition des Längsachse L5 des Aufnahmeelementes 5, die mit der Längsachse des Befestigungsmittels 6 zusammenfällt. Die Längsachse L3 des ersten Elementes 3 schneidet die Längsachse L5 des Aufnahmeelementes 5 im Schnittpunkt S, dessen Position bzw. Lage sich nicht verändert, wenn das Aufnahmeelement 5 mit dem Befestigungsmittel 6 um die Drehachse des Aufnahmeelementes 5 gedreht wird. Beispielhaft ist eine Drehbewegung des Aufnahmeelementes 5 mit dem Befestigungsmittel 6 jeweils um 90° in und entgegen dem Uhrzeigersinn mittels der gestrichelten Kantenlinien und dem Doppelpfeil dargestellt. Korrespondierend zeigt die kleinere Perspektivansicht in Figur 3 die in der Seitenansicht dargestellte Drehung. Daraus wird ersichtlich, dass die Verdrehbarkeit eine bessere Einstellung des Befestigungsmittels 6 ermöglicht, wenn das Befestigungsmittel 6 in angestellter, winkliger Lage zu der Schraubzwinge angeordnet werden soll.The side view of the Figure 3 shows a vertical position of the longitudinal axis L5 of the receiving element 5, which coincides with the longitudinal axis of the fastening means 6. The longitudinal axis L3 of the first element 3 intersects the longitudinal axis L5 of the receiving element 5 at the intersection S, the position or position of which does not change when the receiving element 5 is rotated with the fastening means 6 about the axis of rotation of the receiving element 5. As an example, a rotary movement of the receiving element 5 with the fastening means 6 is shown in each case through 90 ° and counterclockwise by means of the dashed edge lines and the double arrow. Correspondingly, the smaller perspective view shows in Figure 3 the rotation shown in the side view. It can be seen from this that the rotatability enables a better adjustment of the fastening means 6 if the fastening means 6 is to be arranged in an angled position relative to the screw clamp.

Figur 4 zeigt, vergleichbar zu der Figur 3, eine große Frontansicht des ersten Trägerelementes 1 mit dem montierten Befestigungsmittel 6 und eine kleinere Perspektivansicht, die die Drehbewegung der Frontansicht in der Perspektive zeigt. Die gezeigte Drehbewegung in Figur 4 ist eine Drehbewegung um die Längsachse L3 des ersten Elementes 3. Erfindungsgemäß ist eine 360°-Drehung möglich. Das erste Element 3 kann drehbar in dem zweiten Trägerelement 9 oder in einem Loch eines Schweißtisches oder einem Loch eines anderen Bauteils gehalten werden. Somit ergibt sich aus der Kombination der zwei möglichen Drehbewegungen, die in den Figuren 3 und 4 gezeigt sind, eine sehr flexible Zweiachsenanpassbarkeit der Schraubzwinge 2 oder des ersten Trägerelementes 1. Figure 4 shows comparable to that Figure 3 , a large front view of the first support element 1 with the mounted fastener 6 and a smaller perspective view showing the rotational movement of the front view in perspective. The rotation shown in Figure 4 is a rotary movement about the longitudinal axis L3 of the first element 3. According to the invention, a 360 ° rotation is possible. The first element 3 can be rotatably held in the second carrier element 9 or in a hole in a welding table or a hole in another component. This results from the combination of the two possible rotary movements, which in the Figures 3 and 4th are shown, a very flexible two-axis adaptability of the screw clamp 2 or the first carrier element 1.

Figur 5 zeigt in Figur 5a einen Schweißtisch, der eine Arbeitsplatte mit einem vorgegebenen Lochmuster hat. Die Löcher sind insbesondere dazu geeignet, die ersten und/oder zweiten Trägerelemente aufzunehmen. So ist in der Vergrößerung X jeweils ein Beispiel der Schraubzwinge 2 mit einem unterschiedlichen Befestigungsmittel 6 gezeigt. Die links oben gezeigte Gewindespindel 6a hat einen langen Körper, die mittlere Schraubzwinge 2 hält eine kurze Gewindespindel 6a. Die untere Schraubzwinge 2 hält einen Schnellspanner 6b. Mittels des Hebels kann der Schnellspanner 6b mit einem Handgriff von einer fixierenden Stellung in eine gelöste Stellung und umgekehrt gebracht werden. Das zweite Element 10 der Schraubzwingen 2 ist jeweils mit dem unteren freien Ende 10b in die Löcher des Tisches eingesteckt. Die Länge des freien Endes 10b des zweiten Elementes 10, die in das Loch eingesteckt ist, kann mittels nicht gezeigter Klemmringe einstellbar sein. Figure 5 shows in Figure 5a a welding table that has a worktop with a predetermined hole pattern. The holes are particularly suitable for receiving the first and / or second carrier elements. An enlargement X shows an example of the screw clamp 2 with a different fastening means 6. The threaded spindle 6a shown at the top left has a long body, the middle screw clamp 2 holds a short threaded spindle 6a. The lower clamp 2 holds a quick release 6b. By means of the lever, the quick release 6b can be moved from a fixing position into a released position and vice versa in one movement will. The second element 10 of the screw clamps 2 is inserted with the lower free end 10b into the holes in the table. The length of the free end 10b of the second element 10, which is inserted into the hole, can be adjustable by means of clamping rings, not shown.

Weiter zeigt die Figur 5a, dass das erste Trägerelement 1 auch ohne das zweite Trägerelement 9 eingesetzt werden kann. So ist im Bereich der oberen rechten Tischkante ein erstes Trägerelement 1 direkt in eines der Löcher eingesteckt. Links oben ist die Drehbarkeit des Aufnahmeelementes 5 und ein möglicher Einsatzzweck dargestellt, wobei ein zylindrischer Körper gegen einen Winkel auf dem Tisch festgeklemmt ist. Das mittige Beispiel zeigt, dass das erste Trägerelement 1 auch direkt in einen Winkel eingesteckt sein kann und so ein gebogenes Element auf der Tischplatte fixiert werden kann.The shows further Figure 5a that the first carrier element 1 can also be used without the second carrier element 9. In the area of the upper right edge of the table, a first carrier element 1 is inserted directly into one of the holes. Above left, the rotatability of the receiving element 5 and a possible application is shown, a cylindrical body being clamped against the table at an angle. The example in the middle shows that the first carrier element 1 can also be inserted directly at an angle and thus a curved element can be fixed on the table top.

Figur 5b zeigt links die Schraubzwinge 2 in einer Anordnung mit einem minimalen Spannabstand zu einem möglichen Werkstück. Dabei ist das erste Element 3 so weit wie möglich in das kreisringförmige Element 11 eingeschoben und das zweite Element 10 so weit wie möglich in den Tisch. Umgekehrt zeigt die rechte Darstellung einen maximalen Spannabstand mit jeweils weit ausgezogenem ersten und zweiten Element 3, 10. Figure 5b shows the screw clamp 2 on the left in an arrangement with a minimum clamping distance to a possible workpiece. The first element 3 is pushed as far as possible into the annular element 11 and the second element 10 as far as possible into the table. Conversely, the illustration on the right shows a maximum clamping distance, each with the first and second elements 3, 10 extended widely.

Figur 6 zeigt zudem eine Perspektive der ersten Trägerelementes 1 mit einer in dem Aufnahmeelement 5 angeordneten Gewindespindel 6a. Die Darstellung zeigt insbesondere die Dreheinrichtung 7 in einer bevorzugten Ausgestaltung, bei der eine Schraube 7b das Aufnahmeelement 5 sichert, das drehbar an dem Halterelement 4 angeordnet ist. Eine plan geformte, im Wesentlichen runde Fläche 5d der Außenwand 5b des Aufnahmeelementes 5 steht in flächigem Kontakt mit der Innenwand 4c des Halterelementes 4. Das Halterelement 4 weist in der gezeigten Ausführung zwei Schenkel 4a, 4b auf, die beide an einem Ende eine Abrundung 4f aufweisen, die im Wesentlichen mit einer Außenform des ersten Elementes 3 übereinstimmt. Figure 6 also shows a perspective of the first carrier element 1 with a threaded spindle 6a arranged in the receiving element 5. The illustration shows in particular the rotary device 7 in a preferred embodiment, in which a screw 7b secures the receiving element 5, which is rotatably arranged on the holder element 4. A flat-shaped, essentially round surface 5d of the outer wall 5b of the receiving element 5 is in surface contact with the inner wall 4c of the holder element 4. In the embodiment shown, the holder element 4 has two legs 4a, 4b, both of which have a rounded portion 4f at one end have, which essentially corresponds to an outer shape of the first element 3.

Zusammenfassend ist festzuhalten, dass sowohl das erste Trägerelement 1 als auch die Schraubzwinge 2 flexibel u.a. mittels der zwei Drehachsen angepasst werden können. Zudem kann die Länge des ersten Elementes 3 und/oder zweiten Elementes 10 durch Einschieben des jeweiligen Elementes in ein Loch eines Schweißtisches oder dgl. eingestellt werden, so dass eine zusätzliche Anpassungsoption vorhanden ist. Die Reduktion von unerwünschten Drehmomenten wird durch die in einer Ebene angeordneten Achsen ermöglicht. Weiterhin ermöglicht die bevorzugte L-Form des Halterelementes 4, dass eine einseitige Lagerung des Aufnahmeelementes 5 ermöglicht wird, die gewichtsreduzierend wirkt und gleichzeitig eine hohe Formsteifigkeit und mechanische Festigkeit gewährleistet.In summary, it should be noted that both the first carrier element 1 and the screw clamp 2 can be flexibly adapted, inter alia, by means of the two axes of rotation. In addition, the length of the first element 3 and / or second element 10 can be adjusted by inserting the respective element into a hole in a welding table or the like, so that an additional adjustment option is available. The Reduction of unwanted torques is made possible by the axes arranged in one plane. Furthermore, the preferred L-shape of the holder element 4 enables the receiving element 5 to be supported on one side, which has a weight-reducing effect and at the same time ensures a high degree of dimensional stability and mechanical strength.
