Abstract

The tensioning device on a stand (2) for tensioning a rod-form component (3), especially a Christmas tree, includes a force transmission element (4) which by one end is wound on a rotatable tensioning component (5), wherein for operating the rotatable tensioning component, a drive wheel (7) is provided, the diameter of which is a multiple of the diameter of the rotatable tensioning component. The drive wheel shares with the rotatable tensioning component a common axis (18) and is connected to it in a torsionally fixed manner. An independent claim is included for a stand for tensioning a rod-form element, especially a Christmas tree, equipped with the proposed tensioning device.

Description

Die Erfindung betrifft einen Ständer zum Aufspannen eines stabförmigen Teiles, insbesondere eines Christbaumes, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a stand for mounting a rod-shaped part, in particular a Christmas tree, according to the preamble of claim 1.

Insbesondere zum Aufspannen von Christbäumen sind zahlreiche Ständer bekannt, bei denen schwenkbare Halteelemente durch ein oder mehrere auf Zug belastbare, flexible Kraftübertragungselemente verschwenkt werden und dadurch den Christbaum einspannend umgreifen. Das flexible Kraftübertragungselement ist in der Regel ein Stahlseil, oder es besteht aus mehreren Stahlseilen. Es wird durch Führungsöffnungen hindurch geführt, die sich in den Halteelementen meist oberhalb von deren Schwenkachsen befinden. Das mindestens eine Stahlseil wird durch die an dem Ständer befindliche Spanneinrichtung in seiner Wirklänge verkürzt, wodurch die Halteelemente einwärts im Sinne eines Anlegens an das stabförmige Teil verschwenkt werden.In particular, for mounting of Christmas trees, numerous stands are known in which pivotable holding elements are pivoted by one or more resilient to train, flexible power transmission elements and thereby encompass the Christmas tree chucking. The flexible power transmission element is usually a steel cable, or it consists of several steel cables. It is guided through guide openings, which are located in the holding elements usually above their pivot axes. The at least one steel cable is shortened by the clamping device located on the stand in its effective length, whereby the holding elements are pivoted inwardly in the sense of applying to the rod-shaped part.

Beispiele hierfür zeigen DE 39 32 473 C2 , DE 102 20 879 A1 , DE 39 32 432 C2 und DE 201 05 005 U1 . Hier wird ein einziges Stahlseil in Form einer geschlossenen Schlaufe durch alle Halteelemente hindurchgeführt und der Wickelwalze der Spanneinrichtung zugeführt. Die schwenkbaren Halteelemente sind dabei kreis- oder kranzförmig um eine Symmetrieachse des Ständers angeordnet, die zugleich die Längsachse des einzuspannenden stabförmigen Teiles bildet. In Bezug auf diese Symmetrieachse ist die Wickelwalze der Spanneinrichtung tangential gerichtet; sie verläuft also quer zu einer radialen Richtung in Bezug auf die Symmetrieachse.Show examples of this DE 39 32 473 C2 . DE 102 20 879 A1 . DE 39 32 432 C2 and DE 201 05 005 U1 , Here, a single steel cable is passed in the form of a closed loop through all holding elements and fed to the winding roller of the clamping device. The pivotable holding elements are arranged in a circle or ring around an axis of symmetry of the stator, which also forms the longitudinal axis of the rod-shaped part to be clamped. With respect to this axis of symmetry, the winding roller of the clamping device is directed tangentially; it thus extends transversely to a radial direction with respect to the axis of symmetry.

Die genannten bekannten Ständer haben sich in der Praxis bewährt. Es besteht aber der Wunsch, die Bauhöhe dieser Ständer gering zu halten. Hierbei ist die Spanneinrichtung ein gewisses Problem. Sie umfasst neben der Wickelwalze einen beweglichen Spannhebel, der die Wickelwalze nach Art einer Ratsche schrittweise dreht. Das an der Wickelwalze befindliche Seil wird beim Betätigen der Ratsche zunehmend aufgewickelt und gespannt. Ferner bringt die Betätigung durch einen besonderen, zusätzlichen beweglichen Hebel den Nachteil einer verhältnismäßig komplizierten Mechanik mit sich; das gilt gleicherweise für die Herstellung und die Montage.The mentioned known stand have proven themselves in practice. However, there is a desire to keep the overall height of these stands low. Here, the clamping device is a certain problem. It includes in addition to the winding roller a movable clamping lever, which rotates the winding roller in the manner of a ratchet stepwise. The rope located on the winding roller is increasingly wound and tensioned when the ratchet is actuated. Furthermore, the operation by a special, additional movable lever brings the disadvantage of a relatively complicated mechanism with it; this applies equally to the manufacture and assembly.

Aus der DE 203 20 092 U1 ist ein anderer Ständer zum Aufspannen von Christbäumen bekannt, bei dem ein Spannhebel drehfest an den Wickel- oder Spannkörper angesetzt, zum Beispiel eingesteckt wird. Der Spannkörper wird somit durch den Spannhebel direkt verdreht. Hierbei hat der Spannkörper einen größeren Durchmesser als bei Spanneinrichtungen mit einer Wickelwalze, die nach Art einer Ratsche betätigt werden. Zum Arretieren der erreichten Spannstellung ist bei der Spanneinrichtung gemäß der DE 203 20 092 U1 ein nicht näher beschriebenes axiales Rastgesperre zwischen dem Spannkörper und einer Gehäusewand vorgesehen. Es dient dazu, eine einmal erreichte Spannstellung auch nach Loslassen des Spannhebels aufrecht zu erhalten. Derartige axiale Rastgesperre beruhen darauf, dass das zu verdrehende Teil, in diesem Fall der Spannkörper, gegenüber einem feststehenden Rastteil axial verschieblich sein muss, zumindest um die Zahnhöhe der das Rastgesperre bildenden axialen Verzahnung.From the DE 203 20 092 U1 is another stand for mounting Christmas trees known in which a clamping lever rotatably attached to the winding or clamping body, for example, is inserted. The clamping body is thus directly rotated by the clamping lever. Here, the clamping body has a larger diameter than in clamping devices with a winding roller, which are operated in the manner of a ratchet. To lock the reached clamping position is in the clamping device according to the DE 203 20 092 U1 an unspecified axial locking mechanism between the clamping body and a housing wall provided. It serves to maintain a once reached clamping position even after releasing the clamping lever. Such axial locking mechanism based on the fact that the part to be twisted, in this case the clamping body, must be axially displaceable relative to a fixed locking part, at least the tooth height of the locking mechanism forming axial toothing.

Dem Ständer gemäß der DE 203 20 092 U1 lag das Bestreben zugrunde, sämtliche Bauelemente des Ständers unterhalb des oberen Randes seines Aufnahmebereiches anzuordnen, so dass der gesamte Ständer von einem Gehäuse geschlossen abgedeckt werden kann und gegebenenfalls nur die oberen Enden der Halteelemente hervorstehen. Das die Halteelemente betätigende Stahlseil ist deshalb möglichst tief unten in dem Ständer verlegt und greift nach einer ersten Ausführung an den Halteelementen unterhalb von deren Schwenkachse an. Hierzu muss eine komplizierte und reibungsbehaftete Seilumlenkung gewählt werden, oder es sind - nach einer zweiten Ausführungsform - Zwischenhebel erforderlich, die auf die Halteelemente einwirken und erst dadurch die gewünschte Einwärtsbewegung der Halteelemente beim Einspannen des stabförmigen Teiles ermöglichen. Wegen der besonderen Aufgabenstellung ist im Übrigen die Spanneinrichtung bei dem Ständer gemäß der DE 203 20 092 U1 mit in Bezug auf die gemeinsame Symmetrieachse der Halteelemente radial verlaufender Achsrichtung des Wickel- oder Spannkörpers eingebaut. Dieser Ständer baut zwar entsprechend kompakter, als die zuvor genannten Lösungen, insbesondere weil sich die Spanneinrichtung besser in den Außenumfang des Ständers integriert. Er nimmt dafür aber eine recht komplexe, aufwendige und störanfällige Konstruktion in Kauf.The stand according to the DE 203 20 092 U1 was based on the desire to arrange all the components of the stand below the upper edge of its receiving area, so that the entire stand can be covered by a housing closed and possibly only the upper ends of the holding elements protrude. The steel cable which actuates the holding elements is therefore laid as low as possible in the lower part of the stand and, according to a first embodiment, engages the holding elements below its pivot axis. This must be a complicated and frictional cable deflection are selected, or there are - according to a second embodiment - intermediate lever required to act on the holding elements and only thereby allow the desired inward movement of the holding elements when clamping the rod-shaped part. Due to the special task, moreover, the clamping device in the stand according to the DE 203 20 092 U1 installed with respect to the common axis of symmetry of the holding elements radially extending axial direction of the winding or clamping body. Although this stand builds correspondingly more compact than the solutions mentioned above, in particular because the clamping device integrates better in the outer circumference of the stator. But he takes for a rather complex, complex and fault-prone construction in purchasing.

Allen diesen Spanneinrichtungen bzw. Ständern mit Spanneinrichtung ist im Übrigen gemeinsam, dass sie mit dem Spannhebel, sei er nun nach Art einer Ratsche oder anders ausgebildet und im Ständer fest integriert oder wie bei der DE 203 20 092 U1 im Bedarfsfalle aufsteckbar, und mit den komplexen Sperrvorrichtungen eine recht aufwendige und dementsprechend kostspielige, darüber hinaus aber auch - durch Verschleiß, vor allem auch bei Verschmutzung - nicht ganz störungsfreie Konstruktion gewählt haben.All these clamping devices or stands with clamping device is otherwise common that they are with the clamping lever, be it now like a ratchet or otherwise designed and firmly integrated in the stand or as in the DE 203 20 092 U1 plugged in case of need, and with the complex locking devices a rather complex and therefore costly, but also - have chosen not quite trouble-free construction - by wear, especially in case of pollution.

Der Erfindung liegt dementsprechend die Aufgabe zugrunde, einen Ständer mit einer Spanneinrichtung derart auszubilden, dass sie bei leichter Bedienbarkeit und zuverlässiger Betriebsweise insbesondere hinsichtlich des Spannens kostengünstig hergestellt und montiert werden kann.The invention is therefore based on the object, a stand with a clamping device in such a way that it can be inexpensively manufactured and mounted with ease of use and reliable operation, in particular with regard to the clamping.

Diese Aufgabe wird durch einen Ständer mit den Merkmalen gemäß Anspruch 1 gelöst. Zweckmäßige Weiterbildungen sind in den jeweiligen abhängigen Ansprüchen definiert.This object is achieved by a stand having the features according to claim 1. Advantageous developments are defined in the respective dependent claims.

Die Spanneinrichtung hebt sich nach Anspruch 1 vom Stand der Technik darin ab, dass sie auf einen Spannhebel gänzlich verzichtet.The clamping device stands out according to claim 1 from the prior art in that it dispenses entirely with a clamping lever.

Stattdessen ist unmittelbar an dem am Ständer gelagerten verdrehbaren Spannkörper, auf dem das flexible Kraftübertragungselement zum Festspannen des stabförmigen Teils aufwickelbar ist, ein Treibrad vorgesehen.Instead, a drive wheel is provided directly on the rotatable clamping body mounted on the stator, on which the flexible force transmission element can be wound for clamping the rod-shaped part.

Dieses Treibrad hat die gleiche Drehachse wie der verdrehbare Spannkörper. Es kann vorzugsweise mit dem verdrehbaren Spannkörper drehfest verbunden, gegebenenfalls auch mit ihm einstückig ausgebildet sein.This drive wheel has the same axis of rotation as the rotatable clamping body. It may preferably be non-rotatably connected to the rotatable clamping body, optionally also formed integrally with it.

Das Treibrad hat einen Durchmesser, der ein Vielfaches des Durchmessers des verdrehbaren Spannkörpers beträgt. Beispielsweise kann der verdrehbare Spannkörper einen Durchmesser von vorzugsweise 10 mm bis 25 mm und das Treibrad einen solchen von vorzugsweise 75 mm bis 100 mm aufweisen. Dadurch ergibt sich ein Übersetzungsverhältnis, das trotz der erheblichen für das Spannen des flexiblen Kraftübertragungselements erforderlichen Kräfte eine leichte Bedienung der Spanneinrichtung gewährleistet.The drive wheel has a diameter which is a multiple of the diameter of the rotatable clamping body. For example, the rotatable clamping body may have a diameter of preferably 10 mm to 25 mm and the driving wheel one of preferably 75 mm to 100 mm. This results in a gear ratio that ensures easy operation of the clamping device despite the considerable forces required for the tensioning of the flexible power transmission element.

Das Spannen kann dann beispielsweise mit dem Fuße erfolgen, insbesondere wenn das Treibrad, wie nach Anspruch 7 oder 8 vorgesehen, vorzugsweise im Bereich seines Außenumfangs, insbesondere an dem Außenumfang selbst, gleithemmend ausgebildet, insbesondere gezahnt ist. Dabei kann es für die Bedienung von Vorteil sein, wenn der Außenumfang des Treibrades in Richtung seiner Achse konvex gewölbt ausgebildet ist. Denn dann ist das Rad vor allem für eine Bedienung mit dem Fuße besser zugänglich.The clamping can then take place, for example, with the foot, in particular when the drive wheel, as provided according to claim 7 or 8, preferably in the region of its outer periphery, in particular on the outer circumference itself, designed to be slip-resistant, in particular toothed. It may be advantageous for the operation when the outer circumference of the drive wheel is convexly curved in the direction of its axis. Because then the wheel is more accessible, especially for an operation with the foot.

Die Spanneinrichtung verfügt über ein Rastgesperre. Dieses ist so ausgelegt, dass es ein selbsttätiges Zurückdrehen des Spannkörpers beim Spannen des Kraftübertragungselements in einer ersten Stellung, der Raststellung, verhindert, den Spannkörper jedoch in einer zweiten, der Freigabestellung, freigibt, d. h. im Sinne seines Abwickelns sich zurückdreht bzw. zurückdrehen lässt. Bei dieser Freigabestellung ist das Rastgesperre also völlig entkoppelt.The clamping device has a locking mechanism. This is designed so that it prevents an automatic turning back of the clamping body when clamping the power transmission element in a first position, the detent position, the clamping body, however, in a second, the release position releases, d. H. in the sense of its unwinding can be turned back or turned back. In this release position the locking mechanism is thus completely decoupled.

Das Rastgesperre greift vorzugsweise an dem Treibrad an. Es kann vorzugsweise in Form einer Hirth-Verzahnung ausgebildet sein. Jedoch entspricht es der Zielsetzung der Erfindung, eine einfache, kostengünstige und gegen Störungen unanfällige Lösung zur Verfügung zu stellen, besser, wenn das Rastgesperre vorzugsweise am Außenumfang des Treibrades oder in dessen Nähe angreift. Denn dann kann die gleithemmende Ausbildung dieses Außenumfangs zugleich für ein leichtes, bequemes Spannen und für die Sperre des Zurückdrehens beim Spannen nutzbar gemacht werden.The locking mechanism preferably engages the drive wheel. It may preferably be in the form of a Hirth toothing. however It is the object of the invention to provide a simple, inexpensive and against interference prone to solution available, better if the locking mechanism preferably engages the outer periphery of the drive wheel or in the vicinity. Because then the anti-slip training of this outer circumference can be harnessed at the same time for easy, comfortable clamping and for the lock of turning back when clamping.

Dies ergibt nicht nur eine besonders einfache Bauweise. Diese Ausbildung hat zugleich den Vorteil, dass beim Angreifen des Rastgesperres im Bereich des Außenumfangs des Treibrades zugleich das an dieser Stelle vorliegende günstige Übersetzungsverhältnis auch für das Sperren nutzbar gemacht wird. Daraus ergibt sich der weitere Vorteil, dass die auf das Rastgesperre wirkenden Rückstellkräfte der Spanneinrichtung gering sind, die Sperre deshalb insbesondere auch leicht und verschleißarm lösbar ist und das Rastgesperre dementsprechend Material und Kosten sparend leicht ausgelegt werden kann.This not only gives a particularly simple design. This design also has the advantage that when attacking the locking mechanism in the region of the outer periphery of the drive wheel at the same time present at this point favorable gear ratio is also made available for the lock. This results in the further advantage that the forces acting on the locking restoring forces of the clamping device are low, the lock is therefore particularly easy and low-wear solvable and the locking mechanism accordingly material and cost saving can be easily designed.

Dies gilt in besonderem Maße, wenn das Treibrad an seinem Außenumfang - wie in Anspruch 8 vorgesehen - vorzugsweise gezahnt ist, insbesondere, wenn es sich um eine relativ große Zahnung handelt. Denn sie kann insbesondere die bequemere Fußbedienung erheblich erleichtern.This is particularly true when the drive wheel is preferably toothed on its outer periphery - as provided in claim 8, in particular, if it is a relatively large teeth. In particular, it can greatly facilitate the more comfortable foot operation.

Dabei ist es sowohl für das Spannen als auch für das Sperren von besonderem Vorteil, wenn das Treibrad an seinem Außenumfang nach Art eines Hemmrades vorzugsweise eine Zahnung mit Sperrflanken und Gleitflanken aufweist. Denn dann hat die Zahnung eine besonders gute Griffigkeit für den Sperrvorgang.It is for both the clamping and for the locking of particular advantage, if the drive wheel on its outer periphery in the manner of a Hemmrades preferably has a toothing with locking edges and sliding edges. Because then the teeth have a particularly good grip for the locking process.

Besonders vorteilhaft ist dabei eine Ausbildung, bei der die Fläche der Sperrflanke radial ausgerichtet ist. Denn dann ist die Sperrwirkung einerseits gesichert, andererseits wirken der Freigabe die geringstmöglichen Kräfte entgegen.Particularly advantageous is an embodiment in which the surface of the blocking edge is radially aligned. Because then the blocking effect is on the one hand secured, on the other hand, the release counteract the lowest possible forces.

Das Rastgesperre kann grundsätzlich an dem Treibrad vorzugsweise mittels Reibschlusses angreifen. Dies ist besonders dann denkbar, wenn der Angriff am Außenumfang oder in seiner Nähe erfolgt, wo die zum Sperren nötigen Kräfte gering sind. Dies kommt insbesondere in Betracht, wenn das Treibrad dort oder auch das Rastgesperre oder beide gleithemmend ausgebildet sind.The locking mechanism can in principle attack on the drive wheel preferably by means of frictional engagement. This is especially conceivable when the attack takes place on the outer circumference or in its vicinity, where the forces necessary for locking are small. This is particularly considered when the drive wheel there or the locking mechanism or both are designed to prevent sliding.

Eine verlässlichere Gestaltung ergibt sich aber, wenn das Treibrad vorzugsweise als Hemmrad ausgebildet ist und das Rastgesperre eine Sperrklinke ist, die in der Raststellung an mindestens einer der Sperrflanken angreift.A more reliable design, however, results when the drive wheel is preferably designed as an escape wheel and the locking mechanism is a pawl which engages in the locking position on at least one of the locking flanks.

Um das Zurückdrehen des Spannkörpers in jeder Phase des Spannvorganges zu verhindern, ist das Rastgesperre sinnvollerweise in Richtung auf den Außenumfang des Treibrades federnd vorgespannt.To prevent the turning back of the clamping body in each phase of the clamping operation, the locking mechanism is usefully resiliently biased in the direction of the outer circumference of the drive wheel.

Die einfachste, kostengünstigste Gestaltung ergibt sich dabei, wenn das Rastgesperre selbst vorzugsweise als in Richtung auf den Außenumfang des Treibrades vorgespannte federnde Sperrklinke gestaltet ist.The simplest, most cost-effective design results when the locking mechanism itself is preferably designed as biased toward the outer periphery of the drive wheel resilient pawl.

Wenn das Treibrad dann nach Art eines Hemmrades an seinem Außenumfang eine Zahnung mit Sperr- und mit Gleitflanken aufweist, gleitet die Sperrklinke (bei entsprechender Ausrichtung der Flanken) beim Spannen gegen die Federkraft selbsttätig über die Gleitflanken nach Art einer Ratsche in die jeweilige Raststellung. Sie hindert also nicht das Spannen, wohl aber das Zurückdrehen des Spannkörpers in jeder Phase des Spannvorganges.If the traction wheel then has a toothing with locking and with sliding edges in the manner of a Hemmrades on its outer circumference, slides the pawl (with appropriate orientation of the flanks) during clamping against the spring force automatically on the sliding edges in the manner of a ratchet in the respective detent position. So it does not hinder the clamping, but probably the turning back of the clamping body in each phase of the clamping process.

Soll das stabförmige Teil freigegeben werden, so genügt hierfür ein weitgehend kraftfreies Ausrücken der Sperrklinke in die Freigabestellung.If the rod-shaped part to be released, it is sufficient for this purpose a largely force-free disengagement of the pawl in the release position.

Um die Freigabe der Sperrklinke auf einfache Weise, beispielsweise auch mit dem Fuße, zu ermöglichen, ist sie vorzugsweise mit einem Bedienungselement versehen, das in seiner einfachsten Ausführungsform vorzugsweise als einfache, nach außen überstehende und so für die Bedienung zugängliche Verlängerung der Sperrklinke, dieser angeformt, ausgebildet ist.In order to enable the release of the pawl in a simple manner, for example, with the foot, it is preferably provided with a control element, which in its simplest embodiment preferably as a simple, outwardly projecting and accessible to the operator extension of the pawl, this formed , is trained.

Wichtig ist in diesem Falle jedoch, dass die versehentliche Freigabe verhindert wird, was bei der patentgemäßen Vorrichtung besonders leicht möglich wäre, weil sie - wie ausgeführt - auf besondere Leichtgängigkeit ausgelegt ist. Hierfür sind einerseits Verrieglungsvorrichtungen jeglicher Art denkbar. Einfacher, sicherer und zugleich kostengünstiger ist es jedoch, das Bedienungselement vorzugsweise aufsteckbar oder sonst lösbar an der Sperrklinke zu befestigen. Dann kann es auch gesondert z. B. gegen spielende Kinder geschützt, verwahrt und nur für das Auslösen der Freigabestellung angebracht werden.It is important in this case, however, that the accidental release is prevented, which would be particularly easy in the patent device, because - as stated - is designed for particular smoothness. For this purpose, on the one hand Verrieglungsvorrichtungen of any kind are conceivable. However, it is simpler, safer and at the same time cheaper to attach the operating element to the pawl, preferably in a plug-in manner or otherwise detachable. Then it can also separately z. B. protected against playing children, stored and attached only for triggering the release position.

Vorzugsweise ist das Treibrad der Spanneinrichtung in einem Gehäuse so angeordnet, dass es mit seinem Außenumfang, insbesondere seines Profils bzw. seiner Zahnung, aus dessen Oberseite herausragt. Bevorzugt ragt das Treibrad aus der Gehäuseoberseite in einem Quadranten von vorzugsweise 45° bis 60° mit seinem Außenumfang heraus, d. h. ist in diesem Bereich insbesondere für eine Fußbetätigung frei zugänglich.Preferably, the drive wheel of the clamping device is arranged in a housing so that it protrudes with its outer periphery, in particular its profile or its toothing, from the top thereof. Preferably, the drive wheel protrudes from the housing top in a quadrant of preferably 45 ° to 60 ° with its outer circumference, d. H. is freely accessible in this area, in particular for foot operation.

Der Ständer ist weiter ausgestattet mit einem Fußteil, mit einem an dem Fußteil befindlichen Aufnahmebereich für das untere Ende des stabförmigen Teils, mit mehreren um eine Symmetrieachse angeordneten Halteelementen, die jeweils zwischen einer Offenstellung und einer Haltestellung in einer Ebene schwenkbar sind, wobei sich die Ebenen annähernd in der Symmetrieachse schneiden, und mit mindestens einem auf Zug belastbaren flexiblen Kraftübertragungselement, das durch Führungsöffnungen in den Halteelementen vorzugsweise oberhalb von deren Schwenkachsen hindurchgeführt ist, wobei durch Spannen des flexiblen Verbindungsteils mittels der Spanneinrichtung die Halteelemente einwärts im Sinne eines Anlegens an das stabförmige Teil verschwenkt werden. Es können vorzugsweise zwei, drei oder vier Kraftübertragungselemente vorgesehen sein, wobei jedes Kraftübertragungselement ein Halteelement oder eine Gruppe von Halteelementen beaufschlagt. Als Halteelemente sind einfache Halteelemente oder solche mit sogenannter Doppelklaue, wie sie beispielsweise in PCT/EP 01/10039 beschrieben sind, einsetzbar.The stand is further equipped with a foot part, with a located on the foot part receiving portion for the lower end of the rod-shaped part, with a plurality of arranged around an axis of symmetry holding elements which are each pivotable between an open position and a holding position in a plane, wherein the planes cutting approximately in the axis of symmetry, and with at least one loadable on train flexible power transmission element, which is guided through guide openings in the holding elements preferably above the pivot axes, wherein by clamping the flexible connection part by means of the clamping device, the holding elements inwardly in the sense of applying to the rod-shaped part be pivoted. It may preferably be provided two, three or four power transmission elements, wherein each force transmission element acts on a holding element or a group of holding elements. As holding elements are simple holding elements or those with so-called double claw, as they are for example in PCT / EP 01/10039 described, can be used.

Die Spanneinrichtung ist , mit in Bezug auf die Symmetrieachse des Ständers tangential verlaufender Drehachse eingebaut.The clamping device is installed, with respect to the symmetry axis of the stator tangentially extending axis of rotation.

Die Erfindung wird im Folgenden anhand in den Zeichnungen dargestellter Ausführungsbeispiele weiter erläutert. Dabei zeigen:

Figur 1:
einen Ständer mit erfindungsgemäßer Spanneinrichtung; und
Figur 2:
ein Treibrad mit gezahntem Außenumfang in unterschiedlichen Ansichten.
The invention will be explained below with reference to exemplary embodiments illustrated in the drawings. Showing:
FIG. 1 :
a stand with inventive clamping device; and
FIG. 2:
a drive wheel with toothed outer circumference in different views.

Figur 1 zeigt den Ständer 2 zum Aufspannen eines stabförmigen Teils 3 mit Fußteil 12, Aufnahmebereich 13 und Halteelementen 14, die zum Festspannen des stabförmigen Teils - gegebenenfalls gegen die Kraft von Rückholfedern - um Schwenkachsen 16 auf die Symmetrieachse 17 des Ständers zu bewegbar sind. Die Halteelemente 14 sind mit Hilfe des flexiblen Kraftübertragungselements 4, vorzugsweise eines Stahlseils, bewegbar, das in Führungsöffnungen 15 alle Halteelemente 14 gleitend durchsetzt. FIG. 1 shows the stand 2 for mounting a rod-shaped part 3 with foot 12, receiving portion 13 and holding elements 14 which are for clamping the rod-shaped part - possibly against the force of return springs - about pivot axes 16 on the axis of symmetry 17 of the stator to be moved. The holding elements 14 are movable by means of the flexible force transmission element 4, preferably a steel cable, which passes through all the holding elements 14 in guide openings 15 in a sliding manner.

Zum Einspannen des stabförmigen Teils 3 wird das flexible Kraftübertragungselement 4 in der Spanneinrichtung 1 gespannt, die an dem Ständer 2 gelagert ist. Die Spanneinrichtung 1 besteht aus einem verdrehbaren Spannkörper 5, auf dem das flexible Kraftübertragungselement 4 zum Spannen der Halteelemente 14 aufgewickelt wird. Zur Betätigung des Spannkörpers ist ein Treibrad 7 vorgesehen, das an dem Spannkörper 5 mit gleicher Drehachse 18 drehfest verbunden, u. U. auch an ihm angeformt ist. Das Treibrad 7 hat einen Durchmesser, der ein Vielfaches, beispielsweise das Zehnfache, des Durchmessers des Spannkörpers 5 beträgt. Die dadurch erreichte Übersetzung ermöglicht ein - trotz der erforderlichen hohen Spannkräfte - leichtes Spannen und Sperren.For clamping the rod-shaped part 3, the flexible power transmission element 4 is tensioned in the clamping device 1, which is mounted on the stator 2. The clamping device 1 consists of a rotatable clamping body 5, on which the flexible power transmission element 4 is wound to tension the holding elements 14. To actuate the clamping body, a drive wheel 7 is provided, which rotatably connected to the clamping body 5 with the same axis of rotation 18, u. U. is also formed on it. The drive wheel 7 has a diameter which is a multiple, for example, ten times the diameter of the clamping body 5. The result achieved translation allows - despite the required high clamping forces - easy clamping and locking.

Ein Rastgesperre 6 greift im Bereich des Außenumfangs des Treibrades 7 an diesem, vorzugsweise - wie gezeigt - von unten, an. Es ist in Richtung auf das Treibrad 7 federnd vorgespannt oder selbst federnd mit Vorspannung in Richtung auf das Treibrad 7 ausgebildet.A locking mechanism 6 engages in the region of the outer circumference of the drive wheel 7 at this, preferably - as shown - from below to. It is resiliently biased in the direction of the drive wheel 7 or even resiliently formed with bias in the direction of the drive wheel 7.

Das Treibrad 7 ist gezahnt ausgebildet, und zwar nach Art eines Hemmrades mit Sperrflanken 9 und mit Gleitflanken 10. Diese sind so gerichtet, dass die als Sperrklinke 11 ausgebildete Rastsperre 6 beim Spannen des flexiblen Kraftübertragungselements 4 über die Gleitflanken 9 zu den Sperrflanken 10 gleitet und so nach Art einer Ratsche das selbsttätige Zurückdrehen des Spannkörpers 5 in jeder Lage verhindert.The drive wheel 7 is formed toothed, in the manner of a Hemmrades with locking edges 9 and with sliding edges 10. These are directed so that the pawl 11 formed as a locking catch 6 during clamping of the flexible power transmission element 4 via the sliding flanks 9 to the locking flanks 10 slides and so in the manner of a ratchet prevents the automatic turning back of the clamping body 5 in any position.

Die Rastsperre 6, die hier unterhalb des Treibrades 7 gelagert ist, hat ein Bedienungselement 19, das in der einfachsten Form als die Sperrklinke verlängernder, nach außen überstehender Bereich ausgebildet ist, mit dem die Sperrklinke - beispielsweise mit dem Fuß - aus der Raststellung heraus und in die Freigabestellung gedrückt, in der gezeigten Ausführung also nach unten heruntergedrückt werden kann, in welchem Falle die Sperrklinke das Treibrad 7 und mit ihm den Spannkörper, das Kraftübertragungselement und damit letztlich den Stamm freigibt.The locking catch 6, which is mounted here below the drive wheel 7, has a control element 19 which is formed in the simplest form as the pawl extending, outwardly projecting area with which the pawl - for example, with the foot - out of the detent position and pressed in the release position, in the embodiment shown so can be pressed down, in which case the pawl the drive wheel 7 and with him the clamping body, the power transmission element and thus ultimately releases the trunk.

Damit das Rastgesperre nicht versehentlich, beispielsweise durch spielende Kinder, ausgelöst werden kann, kann das Bedienungselement abnehmbar gestaltet sein. Es kann dann nach Art eines Schlüssels solange sicher verwahrt bleiben, bis es zur Auslösung der Freigabestellung benötigt wird. Wie ein Schlüssel kann es dann, ebenso wie die zugehörige Aufnahme an der Sperrklinke oder an der Spanneinrichtung selbst, sogar so gestaltet sein, dass die Bedienung nur mit diesem Bedienungselement möglich ist, wodurch die Sicherung besonders verlässlich wird.So that the locking mechanism can not accidentally, for example, by playing children, triggered, the control element can be made removable. It can then safely kept in the manner of a key until it is needed to trigger the release position. Like a key, it can then, as well as the associated receptacle on the pawl or on the clamping device itself, even be designed so that the operation is possible only with this control element, whereby the fuse is particularly reliable.

Figur 2 zeigt das Treibrad 7 mit seiner Zahnung, insbesondere mit seinen Sperrflanken 9 und Gleitflanken 10 und der konvexen Wölbung seines Außenumfanges im Detail in verschiedenen Ansichten. Im Innern des Treibrades 7 sind nicht bezeichnete Stege beidseitig eines durchgehenden Trägers der Zahnung des Treibrades 7 vorgesehen, welche für das Einsetzen und Festlegen der jeweiligen Enden des Kraftübertragungselementes dienen. FIG. 2 shows the drive wheel 7 with its teeth, in particular with its locking flanks 9 and sliding flanks 10 and the convex curvature of his Exterior in detail in different views. In the interior of the drive wheel 7 are not designated webs on both sides of a continuous carrier of the toothing of the drive wheel 7 is provided, which serve for the insertion and setting of the respective ends of the power transmission element.
