Description

Die Erfindung betrifft einen StƤnder zum Aufspannen eines stabfƶrmigen Teiles, insbesondere eines Christbaumes, gemƤƟ 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.

StƤnder zum Aufspannen von stabfƶrmigen Teilen, insbesondere zum Aufspannen von ChristbƤumen, sind in unterschiedlichen AusfĆ¼hrungen bekannt. Bekannt sind insbesondere auch StƤnder, bei denen schwenkbare Halteelemente durch ein oder mehrere auf Zug belastbare, flexible KraftĆ¼bertragungselemente verschwenkt werden und dadurch den Christbaum einspannend umgreifen. Das flexible KraftĆ¼bertragungselement ist in der Regel ein Stahlseil, oder es besteht aus mehreren Stahlseilen. Es wird durch FĆ¼hrungsƶffnungen, die sich in den Halteelementen meist oberhalb von deren Schwenkachsen befinden, gleitend hindurch gefĆ¼hrt. Das mindestens eine Stahlseil wird durch eine an dem StƤnder befindliche Spanneinrichtung in seiner WirklƤnge verkĆ¼rzt, wodurch die Halteelemente einwƤrts im Sinne eines Anlegens an das stabfƶrmige Teil verschwenkt werden.Stands for mounting rod-shaped parts, in particular for mounting Christmas trees, are known in different designs. In particular, stands are also known in which pivotable holding elements are pivoted by one or more train-loadable, flexible power transmission elements, thereby embracing the Christmas tree. 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, slidably. The at least one steel cable is shortened by a 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 hierfĆ¼r zeigen DE 39 32 473 C2 , DE 102 20 879 A1 , und DE 201 05 005 U1 . Hier wird ein einziges Stahlseil in Form einer geschlossenen Schlaufe durch alle Halteelemente hindurchgefĆ¼hrt und der Wickelwalze der Spanneinrichtung zugefĆ¼hrt. Die schwenkbaren Halteelemente sind dabei kreis- oder kranzfƶrmig um eine Symmetrieachse des StƤnders angeordnet, die zugleich die LƤngsachse des einzuspannenden stabfƶrmigen Teiles bildet.Show examples of this DE 39 32 473 C2 . DE 102 20 879 A1 , 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.

Die genannten bekannten StƤnder haben sich in der Praxis bewƤhrt. Allerdings ist ihre Herstellung verhƤltnismƤƟig aufwendig, weil sie aus einer Vielzahl von teilweise recht komplexen Bauteilen, zudem aus unterschiedlichen Materialien, zusammengesetzt sind, wie beispielsweise Kunststoffbauteile fĆ¼r FuƟteil, Aufnahmebereich und etwa auch eine Abdeckung einerseits und stƤhlerne Bauteile wie Schwenkachsen, Schwenkhebel, Halteplatten, Halteklauen, Federn, Niete, Schrauben, Ratschen, Stahlseile usw. andererseits. Dabei sind diese Einzelteile nur zum Teil Standardprodukte, zu einem anderen Teil aber Sonderanfertigungen fĆ¼r den speziellen StƤnder, die noch dazu nur in sehr begrenzter StĆ¼ckzahl benƶtigt werden, was sich nachteilig auf die Herstellungskosten der StƤnder auswirkt. Die KomplexitƤt der Bauweise macht diese StƤnder im Ć¼brigen auch fĆ¼r Stƶrungen , z.B. durch Verschmutzung oder durch VerschleiƟ, anfƤllig.The mentioned known stand have proven themselves in practice. However, their production is relatively expensive because they are composed of a variety of sometimes quite complex components, also made of different materials, such as plastic components for footboard, receiving area and about a cover on the one hand and steel components such as swivel axes, pivoting lever, retaining plates, retaining claws , Springs, rivets, screws, ratchets, steel cables, etc. on the other hand. These items are only partially standard products, to another part but custom-made for the special stand, which are still required only in very limited quantities, which adversely affects the cost of manufacturing the stand. Incidentally, the complexity of the design also makes these stands susceptible to interference, e.g. due to contamination or wear, prone.

Die genannten Nachteile vermeiden baulich einfachere, robustere und preiswertere StƤnder wie beispielsweise der StƤnder gemƤƟ DE 39 32 473 C2 Figur 4, bei dem die Halteelemente und das Aufnahmeteil einstĆ¼ckig aus einem federnden Material wie Federstahl oder - gegebenenfalls verstƤrkten - Kunststoffen geformt sind. Die einzelnen, als federnde BĆ¼gel oder Laschen ausgebildeten Halteelemente lassen sich ebenfalls unter der Kraft des KraftĆ¼bertragungselementes an den einzuspannenden Stamm anlegen und kehren bei Wegnahme der Kraft auf Grund ihrer EigenelastizitƤt wieder in die Lƶsestellung zurĆ¼ck. Dabei lƤsst sich die Federwirkung der Halteelemente dadurch verbessern, dass das Material im Ɯbergangsbereich zwischen den Halteelementen und dem Aufnahmeteil durch geeignete Fertigungsschritte, beispielsweise durch Ausbildung von EinschnĆ¼rungen, eine SchwƤchung erfƤhrt.The disadvantages mentioned avoid structurally simpler, more robust and cheaper stands such as the stand according to DE 39 32 473 C2 Figure 4, in which the holding elements and the receiving part are integrally formed from a resilient material such as spring steel or - optionally reinforced - plastics. The individual, designed as a resilient strap or tabs holding elements can also create under the force of the power transmission element to be clamped trunk and return when removing the force due to their inherent elasticity back to the release position. In this case, the spring action of the retaining elements can be improved by the fact that the material undergoes weakening in the transition region between the retaining elements and the receiving part by suitable manufacturing steps, for example by the formation of constrictions.

Diese sehr einfache Bauweise hat freilich den Nachteil, dass die ElastizitƤt der Halteelemente, die in keiner Richtung ausreichend gefĆ¼hrt sind, auch in der Haltestellung in unerwĆ¼nschter Weise erhalten bleibt, so dass der Stamm nicht wirklich fest eingespannt werden kann.Of course, this very simple design has the disadvantage that the elasticity of the holding elements, which are sufficiently guided in any direction, is retained in the holding position in an undesirable manner, so that the strain can not really be clamped firmly.

Hieraus ergibt sich die Aufgabe, einen StƤnder der eingangs genannten Art so zu verbessern, dass er ohne Verlust an StabilitƤt preiswerter herstellbar ist, indem die Zahl der fĆ¼r seine Herstellung benƶtigten Bauteile verringert wird, wobei zugleich nach Mƶglichkeit teure Stahlbauteile durch preiswerteren Kunststoff ersetzt werden und gleichzeitig der Arbeitsaufwand fĆ¼r den Zusammenbau verringert und eine etwa nƶtige Reparatur erleichtert wird.This results in the task to improve a stand of the type mentioned so that it can be produced less expensive without loss of stability, by reducing the number of components needed for its manufacture, while at the same time replacing expensive steel components with cheaper plastic as far as possible while at the same time reducing the labor required for assembly and facilitating any necessary repair.

Diese Aufgabe wird durch einen StƤnder mit den Merkmalen gemƤƟ Anspruch 1 gelƶst. ZweckmƤƟige Weiterbildungen sind in den UnteransprĆ¼chen definiert.This object is achieved by a stand having the features according to claim 1. Advantageous developments are defined in the subclaims.

Der erfindungsgemƤƟe StƤnder besteht aus einem FuƟteil mit einem daran befindlichen Aufnahmebereich fĆ¼r das Befestigungsende eines stabfƶrmigen Teiles, etwa eines Christbaumes, mit mehreren um seine Symmetrieachse angeordneten Halteelementen.The stand according to the invention consists of a foot part with a receiving area located thereon for the attachment end of a rod-shaped part, such as a Christmas tree, with a plurality of holding elements arranged about its axis of symmetry.

Diese Halteelemente sind in Lagerbƶcken gehalten, die auf dem FuƟteil angeordnet bzw. als integraler Bestandteil des als FuƟteil verwendeten Formteils oder eines vorzugsweise daran befestigten Aufsatzteils ausgebildet sind.
Die Halteelemente sind gegen Federkraft aus einer Offenstellung in eine Haltestellung jeweils in einer Schwenkebene schwenkbar, wobei sich die Schwenkebenen annƤhernd in der Symmetrieachse des StƤnders schneiden.These holding elements are held in bearing blocks, which are arranged on the foot part or formed as an integral part of the molded part used as a foot part or a preferably attached thereto attachment part.
The retaining elements are pivotable against spring force from an open position to a holding position in each case in a pivot plane, wherein the pivot planes intersect approximately in the axis of symmetry of the stator.

Die Halteelemente werden von mindestens einem mittels einer Spanneinrichtung betƤtigbaren, auf Zug belastbaren flexiblen KraftĆ¼bertragungselement, etwa einem oder auch mehreren Stahlseilen, aus der Offenstellung in die Haltestellung gebracht, wobei bei der sogenannten Mehrseiltechnik jedes KraftĆ¼bertragungselement zumindest an einem Halteelement angreift. Dies geschieht dadurch, dass das KraftĆ¼bertragungselement die Halteelemente oberhalb ihrer Schwenkachsen in FĆ¼hrungsƶffnungen der Halteelemente querverschieblich gleitend gefĆ¼hrt umgreift, so dass die Halteelemente bei dem verkĆ¼rzenden Spannen des KraftĆ¼bertragungselement (Seils) in Richtung auf die Symmetrieachse in die Haltestellung verschwenkt werden.The holding elements are brought from the open position to the holding position by at least one actuatable by train, tensile loadable flexible power transmission element, such as one or more steel cables, wherein in the so-called multi-cable technology engages each force transmission element at least on a holding element. This happens because the force transmission element, the holding elements above its pivot axes in guide openings of the holding elements slidably guided slidingly engages, so that the holding elements are pivoted in the shortening clamping of the power transmission element (rope) in the direction of the axis of symmetry in the holding position.

Die Halteelemente bestehen in ihrem oberen Bereich, in dem die SpannkrƤfte des Seiles und die HaltekrƤfte angreifen, aus einem formsteifen Haltebereich, der beim Spannen zur Anlage und zum Halten an das stabfƶrmige Teil kommt. Unterhalb dieses Haltebereichs schlieƟt sich ein sich nach unten erstreckendes elastisches Element an, das am Haltebereich befestigt oder vorzugsweise mit dem Haltebereich einstĆ¼ckig ausgeformt sein kann, und mittels dessen das jeweilige Halteelement in dem jeweiligen Lagerbock lagerbar ist.The holding elements consist in their upper region, in which attack the clamping forces of the rope and the holding forces, from a dimensionally stable holding area, which comes when clamping to the plant and to hold the rod-shaped part. Below this holding region, a downwardly extending elastic element adjoins, which may be fastened to the holding region or preferably integrally formed with the holding region, and by means of which the respective holding element can be stored in the respective bearing block.

Vorzugsweise ist das elastische Element so ausgebildet und so im Lagerbock gelagert, dass das Halteelement um keine feste Schwenkachse schwenkbar ist, d.h. das es eine gedachte, wandernde Schwenkachse hat. Der Weg, um den die Schwenkachse wandert, hƤngt dabei vom Winkel ab, um den das Halteelement verschwenkt wird.Preferably, the elastic member is formed and supported in the bearing block so that the holding member is pivotable about no fixed pivot axis, i. that it has an imaginary, wandering pivot axis. The path by which the pivot axis travels depends on the angle at which the holding element is pivoted.

Das elastische Element kann nicht nur als einfaches sich nach unten erstreckendes Bauteil ausgebildet sein, sondern kann insbesondere als eine V-fƶrmig nach oben offene Blattfeder ausgebildet sein, deren einer Schenkel am Haltebereich des Halteelements angebracht bzw. vorzugsweise angeformt ist und dessen anderer, freier Schenkel in Richtung auf die Symmetrieachse des StƤnders nach oben weist. Durch diese Bauweise lƤsst sich - bei entsprechender Gestaltung der Aufnahmen fĆ¼r die Halteelemente eien besonders gute FĆ¼hrung zwischen dem jeweiligen Halteelement und seiner Aufnahme und Lagerung in seiner Aufnahme realisieren.The elastic element can not only be formed as a simple downwardly extending component, but can in particular be designed as a V-shaped upwardly open leaf spring, one leg of which is attached to the holding region of the holding element or preferably formed and the other, free leg facing upward in the direction of the symmetry axis of the stator. This design allows - with appropriate design of the recordings for the holding elements eien particularly good leadership between the respective holding element and its recording and storage in its recording realize.

Insbesondere bei der einstĆ¼ckigen Ausbildung von Halteelement und elastischem Element ergibt sich der weitere wesentliche Vorteil, dass die Halteelemente als einfache Spritzgussteile, beispielsweise aus einem geeigneten Kunststoff hinreichender Festigkeit, hergestellt werden kƶnnen.In particular, in the one-piece design of retaining element and elastic element, there is the further significant advantage that the retaining elements can be produced as a simple injection-molded parts, for example, from a suitable plastic of sufficient strength.

Der Querschnitt des elastischen Elements ist vorzugsweise in dessen LƤngsrichtung sich so Ƥndernd ausgebildet, dass das elastische Element bzw. die Feder ein TrƤger mit im Wesentlichen konstanter Biegespannung ist.The cross section of the elastic element is preferably designed to change in its longitudinal direction so that the elastic element or the spring is a carrier with a substantially constant bending stress.

Die Halteelemente kƶnnen durch bloƟes Einstecken in dafĆ¼r im jeweiligen Lagerbock vorgesehene und entsprechend geformte Ausnehmungen bzw. Aufnahmen gelagert sein. In diesem Falle werden sie vorzugsweise durch das sie umgreifende Seil, u.U. auch durch eine einen Formschluss gewƤhrende Formgebung in ihrem Sitz gehalten. ZusƤtzlich kann aber auch, vorzugsweise am freien Ende der elastischen Elemente, eine Verrastung vorzugsweise mit einem Endnocken vorgesehen sein.The holding elements can be stored by simply plugging it into provided in the respective bearing block and correspondingly shaped recesses or recordings. In this case, they are preferably by the embracing rope, u.U. also held by a form-fitting shaping in their seat. In addition, however, preferably also be provided with an end cam, preferably at the free end of the elastic elements, a latching.

Die Halteelemente und ihre Aufnahmen im jeweiligen Lagerbock sind so ausgebildet, dass die Halteelemente im Lagerbock beim Spannen des Seils aus der Offenstellung in die Haltestellung schwenken kƶnnen. Dazu sind die Halteelemente mit ihren elastischen Elementen in den Aufnahmen schwenkbeweglich um die wandernde Schwenkachse gelagert.The holding elements and their recordings in the respective bearing block are designed so that the holding elements in the bearing block during the tensioning of the rope from the open position can pivot into the holding position. For this purpose, the holding elements are mounted with their elastic elements in the receptacles pivotally about the migratory pivot axis.

Dies kann beispielsweise bei einem sich nur nach unten in die Aufnahme hinein erstreckenden elastischen Element in der Weise erfolgen, dass es mit seinem unteren Ende im Grund der Aufnahme gehaltert, eventuell auch verrastet ist, wƤhrend es oberhalb dieser Halterung in Richtung auf die Symmetrieachse frei beweglich ist.This can be done, for example, in a downwardly into the receptacle extending into the elastic element in such a way that it is held with its lower end in the bottom of the receptacle, possibly also locked, while it is freely movable above this support in the direction of the axis of symmetry is.

Bei der Ausbildung des elastischen Elements als nach oben offenes V bedarf es nicht einmal einer solchen besonderen Halterung am Boden der Aufnahme. Das V schmiegt sich bei entsprechender Ausformung der Aufnahme vollflƤchig an deren WƤnde an, ohne dass deshalb die Schwenkbeweglichkeit in radialer Richtung, d.h. in Richtung auf die Symmetrieachse, verloren geht.In the formation of the elastic member as an open-top V, it does not even require such a special holder on the bottom of the recording. The V nestles with appropriate shape of the recording over its entire surface on the walls, without therefore the pivoting movement in the radial direction, i. in the direction of the axis of symmetry, is lost.

In jedem Falle verzichtet diese Konstruktion in Abwendung von dem diesbezĆ¼glichen Stand der Technik auf eine den Zusammenbau komplizierende physische Schwenkachse fĆ¼r die Halteelemente. Die Schwenkachse 12 der Halteelemente ist also nur als ideelle Achse zu verstehen, die zudem nicht lagefest ist.In any case, this construction avoids, in contrast to the related art, an assembly-complicating physical pivot axis for the support members. The pivot axis 12 of the holding elements is therefore to be understood only as an ideal axis, which is also not stable in position.

Um trotz des Fehlens der FĆ¼hrung durch eine physische Schwenkachse eine hinreichende seitliche FĆ¼hrung der Halteelemente in ihrer Schwenkbewegung beim Spannen zu gewƤhrleisten und die Haltebereiche zugleich in ihrer Haltefunktion in der Haltestellung zu unterstĆ¼tzen, sind an den Halteelementen und an den Lagerbƶcken einander entsprechende, zur Schwenkebene des jeweiligen Halteelements parallele FĆ¼hrungsflƤchen zur FĆ¼hrung der Schwenkbewegung ausgebildet. Diese FĆ¼hrungsflƤchen erstrecken sich zur GewƤhrleistung einer bestmƶglichen FĆ¼hrung Ć¼ber die gesamte LƤnge und Breite der Halteelemente einschlieƟlich der elastischen Bereiche und des formsteifen Haltebereichs, soweit letzterer nicht aus der Aufnahme herausragt.In spite of the lack of guidance by a physical pivot axis to ensure sufficient lateral guidance of the holding elements in their pivotal movement during clamping and the holding areas at the same time in their To support holding function in the holding position, are on the holding elements and on the bearing blocks each other, parallel to the pivot plane of the respective holding element guide surfaces for guiding the pivoting movement formed. These guide surfaces extend to ensure the best possible guidance over the entire length and width of the holding elements including the elastic regions and the dimensionally stable holding region, as far as the latter does not protrude from the receptacle.

Das so gestaltete Halteelement hebt sich vom dargestellten Stand der Technik des weiteren dadurch vorteilhaft ab, dass es zugleich die der Schwenkbewegung entgegenwirkende Federkraft bereitstellt, ohne dass hierfĆ¼r eigene Bauteile, etwa eine Zugfeder je Halteelement, bereitgestellt und beim Zusammenbau montiert werden mĆ¼ssten.The retaining element designed in this way also stands out from the illustrated prior art advantageously in that at the same time it provides the spring force counteracting the pivotal movement without having to provide its own components, such as a tension spring per retaining element, and to mount it during assembly.

Die so ausgebildeten Halteelemente kƶnnen zur Verbesserung der Funktion des StƤnders noch dadurch optimiert werden, dass oberhalb ihrer formsteifen Haltebereiche in Richtung der Symmetrieachse des StƤnders abwƤrts geneigte FĆ¼hrungsflƤchen zur Erleichterung des EinfĆ¼hrens des stabfƶrmigen Teiles angeformt werden.The holding elements formed in this way can be further optimized to improve the function of the stand, that above their dimensionally stable holding areas in the direction of the axis of symmetry of the stand downwardly inclined guide surfaces are formed to facilitate the insertion of the rod-shaped part.

Insgesamt ergibt sich so ein StƤnder, der mit einer stark verringerten Zahl einfach strukturierter Bauteile auskommt, die zudem leicht herstellbar sind, insbesondere ohne weiteres in einem preiswerten Spritzgussverfahren hergestellt werden kƶnnen und ebenso leicht montierbar bzw. demontierbar und damit leicht auswechselbar sind.Overall, this results in a stand that manages with a greatly reduced number of simple structured components, which are also easy to produce, in particular can be easily produced in a low-cost injection molding and also easy to assemble or disassemble and thus easily replaceable.

Als Spanneinrichtung fĆ¼r das zumindest eine KraftĆ¼bertragungselement dient vorzugsweise ein fuƟbetƤtigtes Treibrad, das mittels eines Rastgesperres ein Spannen in einer Haltestellung und ein selbsttƤtiges ZurĆ¼ckdrehen in eine Freigabestellung ermƶglicht.As a tensioning device for the at least one force transmission element is preferably a foot-operated drive wheel, which allows by means of a Rastgesperres a clamping in a holding position and an automatic turning back into a release position.

Die Erfindung wird im Folgenden anhand eines in den Zeichnungen dargestellten AusfĆ¼hrungsbeispiels weiter erlƤutert. Dabei zeigen:

Figur 1 zeigt den StƤnder 1 zum Aufspannen eines stabfƶrmigen Teils 2 mit einem FuƟteil 3, dem Aufnahmebereich 4 fĆ¼r das Befestigungsende 5 des stabfƶrmigen Teiles 2 und mit Halteelementen 8. Die Halteelemente 8 sind in Lagerbƶcken 7 gelagert und sind in Schwenkebenen 9 (vgl hierzu Figur 8), die sich annƤhernd in der Symmetrieachse 6 schneiden, zum Festspannen des stabfƶrmigen Teils 2 gegen ihre eigene Federkraft um ideelle Schwenkachsen 12 auf die Symmetrieachse 6 des StƤnders zu bewegbar. Die Halteelemente 8 sind mittels des durch die Spanneinrichtung 10 gespannten, flexiblen KraftĆ¼bertragungselements 11 in Form eines Stahlseils bewegbar, das in FĆ¼hrungsƶffnungen 13 alle Halteelemente 8 gleitend umfasst oder durchsetzt. Figure 1 shows the stand 1 for mounting a rod-shaped part 2 with a foot part 3, the receiving area 4 for the attachment end 5 of the rod-shaped part 2 and with holding elements 8. The holding elements 8 are mounted in bearing blocks 7 and are in pivoting planes 9 (see FIG 8), which intersect approximately in the axis of symmetry 6, for clamping the rod-shaped part 2 against its own spring force to non-ideal pivot axes 12 on the axis of symmetry 6 of the stator to be moved. The holding elements 8 are movable by means of the stretched by the tensioning device 10, flexible power transmission element 11 in the form of a steel cable, which comprises in guide openings 13, all holding elements 8 slidably or passes through.

Zum Einspannen des stabfƶrmigen Teils 2 wird das flexible KraftĆ¼bertragungselement 11 in der Spanneinrichtung 10 gespannt, die an dem StƤnder 1 gelagert ist. Die Spanneinrichtung kann unterschiedlich ausgebildet sein. Hier wird nur andeutungsweise eine Wickelwalzenkonstruktion gezeigt, die - beispielsweise' in FuƟbedienung - durch ein Treibrad angetrieben wird, das einen vielfach grĆ¶ĆŸeren Durchmesser als die Wickelwalze hat und das durch einen Sperrklinkenmechanismus bzw. ein Rastgesperre am unbeabsichtigten Freigeben der Spannung gehindert wird.For clamping the rod-shaped part 2, the flexible force transmission element 11 is tensioned in the tensioning device 10, which is mounted on the stator 1. The clamping device can be designed differently. Here, only a hint of a winding roller construction is shown, which - for example, in foot control - is driven by a drive wheel, which has a diameter much larger than the winding roller and by a Pawl mechanism or a locking mechanism is prevented from unintentional release of the voltage.

Die Figur zeigt Halteelemente 8 die in Aufnahmen 17 in Lagerbƶcken 7 gehalten sind, wobei die Lagerbƶcke hier nicht mit dem FuƟteil 3 verbunden oder mit ihm einstĆ¼ckig ausgebildet sind, sondern mit einem Aufsatzteil 19 verbunden bzw. mit ihm einstĆ¼ckig ausgeformt sind, welches seinerseits mit dem FuƟteil 3 fest verbundenen ist.The figure shows holding elements 8 which are held in receptacles 17 in bearing blocks 7, wherein the bearing blocks are not connected here with the foot part 3 or formed integrally with it, but connected to an attachment 19 and integrally formed with him, which in turn with the Foot part 3 is firmly connected.

Die Figur 1 zeigt weiter zwei der Halteelemente 8 mit ihren formsteifen Haltebereichen 14, den darin eingeformten FĆ¼hrungsƶffnungen 13 fĆ¼r das KraftĆ¼bertragungselement 11, den oberhalb angeformten FĆ¼hrungsflƤchen 18 zur Erleichterung des EinfĆ¼hrens des stabfƶrmigen Teiles 2 sowie - andeutungsweise - das jeweils unterhalb des formsteifen Haltebereichs angesetzte bzw. angeformte elastische Element 15 als V-fƶrmig nach oben offene Blattfeder, an deren freiem Ende Rastelemente 16 zur Verrastung an der Aufnahme 17 und Nasen 20 zum Lƶsen der Verrastung erkennbar sind.FIG. 1 further shows two of the holding elements 8 with their dimensionally stable holding regions 14, the guide openings 13 for the force transmission element 11 formed therein, the guide surfaces 18 formed above for facilitating the insertion of the rod-shaped part 2 and - hinted at - the respectively below the dimensionally stable holding region formed elastic element 15 as V-shaped upwardly open leaf spring, at the free end locking elements 16 for locking on the receptacle 17 and lugs 20 for releasing the locking can be seen.

Figur 2 zeigt denselben StƤnder in einem anderen Schnitt, der die Form und den Sitz der Halteelemente 8 in ihrer jeweiligen Aufnahme 17 deutlich zeigt. Sie zeigt die kompakten formsteifen Haltebereiche 14 mit FĆ¼hrungsƶffnungen 13, FĆ¼hrungsflƤchen 18 zur Erleichterung des EinfĆ¼hrens des stabfƶrmigen Teiles 2 sowie das an den formsteifen Haltebereich 14 angeformte elastische Element 15 als V-fƶrmige, nach oben offene Blattfeder, deren freier Schenkel zur Symmetrieachse 6 weist und der an seinem freien Ende die Rastelemente 16 zur Verrastung in der Aufnahme 17 und eine daran angeformte Nase 20 trƤgt, mittels derer die Verrastung aufgehoben werden kann, wenn das Halteelement, beispielsweise zur Reinigung des StƤnders oder zum Zwecke des Auswechselns herausgenommen bzw. ausgetauscht werden muss. Diese Zeichnung veranschaulicht besonders, wie der erfindungsgemƤƟe StƤnder die nƶtige StabilitƤt ohne eine physische Achslagerung des Halteelements herstellt, nƤmlich insbesondere dadurch, dass radial wirkende KrƤfte durch das elastische Element und axial wirkende KrƤfte durch seitlich die Halteelemente fĆ¼hrende FĆ¼hrungsflƤchen in der Aufnahme 17 aufgenommen werden. Figure 2 shows the same stand in a different section, which clearly shows the shape and the seat of the holding elements 8 in their respective receptacle 17. It shows the compact dimensionally stable holding portions 14 with guide openings 13, guide surfaces 18 to facilitate insertion of the rod-shaped part 2 and molded onto the dimensionally stable holding portion 14 elastic element 15 as a V-shaped, upwardly open leaf spring whose free leg to the axis of symmetry 6 and which at its free end, the locking elements 16 for locking in the receptacle 17 and a molded-on nose 20 carries, by means of which the latching can be canceled when the holding element, for example, to remove the stand or for the purpose of replacement taken out or replaced , This drawing illustrates in particular how the stand according to the invention produces the necessary stability without a physical axial bearing of the holding element, namely in that radially acting forces are absorbed by the elastic element and axially acting forces by guide surfaces leading laterally in the receptacle 17.

Figuren 3 und 4 zeigen das erfindungsgemƤƟe Halteelement 8 in seiner AusfĆ¼hrung mit dem elastischen Element 15 als V - fƶrmig nach oben offene Blattfeder im Detail einschlieƟlich des formsteifen Haltebereichs 14, der oberhalb angeordneten FĆ¼hrungsflƤche 18, der FĆ¼hrungsƶffnung 13, des an den formsteifen Haltebereich 14 angeformten elastischen Elements 15 mit Rastelement 16, Nase 20 und der ideellen beim Verschwenken wandernden Schwenkachse 12. Figures 3 and 4 show the holding element 8 according to the invention in its execution with the elastic element 15 as a V-shaped upwardly open leaf spring in detail including the dimensionally stable holding portion 14, the above guide surface 18, the guide opening 13, integrally formed on the dimensionally stable holding portion 14 elastic element 15 with locking element 16, nose 20 and the ideal pivotal pivoting pivot axis 12th

Die Figuren veranschaulichen die Vorteile der vorliegenden Erfindung in besonderem MaƟe, und zwar insbesondere dadurch, dass dieses Bauteil, das die Funktionen mehrerer Bauteile des Standes der Technik, nƤmlich die von Schwenkhebeln, Halteklauen, Schwenkachsen, RĆ¼ckholfedern und verschiedenen FĆ¼hrungsflƤchen in sich vereinigt und so bereits einen erheblichen konstruktiven und Montageaufwand erspart, zudem noch auƟerordentlich gĆ¼nstig als einfaches Formteil, beispielsweise als KunststoffguƟ, hergestellt werden kann.The figures illustrate the advantages of the present invention to a particular extent, and in particular by the fact that this component, which combines the functions of several prior art components, namely the pivoting levers, retaining claws, pivot axes, return springs and various guide surfaces and so already saves a considerable amount of design and assembly effort, also still extremely low as a simple molding, for example, as a plastic molding, can be produced.

Dies gilt besonders, wenn berĆ¼cksichtigt wird, dass dieses Formteil nur an bestimmten Stellen besonders steif ausgebildet sein muss, dort nƤmlich, wo die Spann- und HaltekrƤfte zu Ć¼bertragen und aufzunehmen sind, und dass selbst dort, also beispielsweise im Haltebereich 14, eine materialsparende Verarbeitung mit Ausnehmungen und Aussteifungen bzw. Hinterschnitten mƶglich ist. Dies gilt vor allem fĆ¼r die stĆ¼tzende seitliche FĆ¼hrung der Halteelemente durch die parallelen FĆ¼hrungsflƤchen an ihnen und an den InnenflƤchen der Aufnahmen 17 der zugeordneten Lagerbƶcke. Auch die oberhalb des formsteifen Haltebereichs angeordneten FĆ¼hrungsflƤchen 18 kƶnnen im Ć¼brigen an dem Haltebereich mit einem materialsparenden Hinterschnitt und etwa mit einer VerstƤrkungsrippe ausgebildet sein.This is especially true when it is taken into account that this molded part only has to be designed to be particularly rigid at certain points, namely where the clamping and holding forces are to be transmitted and received, and that even there, ie, for example in the holding area 14, a material-saving processing with recesses and stiffeners or undercuts is possible. This is especially true for the supporting lateral guidance of the holding elements by the parallel guide surfaces on them and on the inner surfaces of the receptacles 17 of the associated bearing blocks. The guide surfaces 18 arranged above the dimensionally stable holding region can also be formed on the holding region with a material-saving undercut and, for example, with a reinforcing rib.
