Definitions
- the invention relates to a stand for mounting mast or rod-shaped parts, in particular for mounting Christmas trees, according to the preamble of claim 1.
- a generic stand for mounting mast or trunk-shaped parts, especially for mounting Christmas trees is, for example, from DE 10 2007 025 227 A1 known.
- a known stand of this type comprises, for example, a base plate on which supporting devices are provided, for example for holding a Christmas tree.
- these support devices comprise a plurality of levers or holding elements which are arranged spaced apart around a vertical central axis and can be pivoted around horizontal axes and which can essentially be clamped towards the central axis. The clamping forces are applied via a clamping device.
- a generic stand can have a central receiving space for inserting the lower end of a Christmas tree to be fixed, with the entire arrangement next to the base plate comprising a housing rising above the base plate, specifically with the mentioned central receptacle for inserting a tree trunk to be fixed.
- the levers already mentioned and which can be pivoted onto the tree trunk protrude through a corresponding opening on the top of the housing cover.
- the forces to be applied by the clamping device are introduced into a wall structure or into a wall contour.
- Another generic stand for mounting mast or trunk-shaped parts, in particular for mounting Christmas trees according to the preamble of claim 1 is, for example, from DE 20 2011 100 103 U1 known.
- the object of the present invention is to provide an improved stand for mounting mast or rod-shaped parts, in particular Christmas trees, which has greater stability and is also simple and inexpensive to manufacture.
- the stand according to the invention has increased stability, since a counterforce transmitted from the holding elements to the tensioning device via the force transmission device is absorbed by the stabilizing component. Consequently, the recording space defining and this enclosing wall structure can be made less stable and can be made, for example, from a thinner and possibly more cost-effective material. Due to the fact that the stabilizing component is attached to the base plate by means of the guide device, the stand can be produced easily and inexpensively. For example, the base plate can be produced together with the wall structure using an injection molding process. The clamping device is in direct contact with the stabilizing component.
- the reaction force corresponding to the clamping force of the clamping device is transmitted to the base plate of the stand via the stabilizing component.
- the feature according to which the second material has greater strength than the first material is to be understood in such a way that in the case of workpieces of the same geometry that are subjected to the same stress (tension, pressure, bending, shearing), a workpiece made of the second material is formed has greater strength than a workpiece formed from the first material.
- the pivot axes about which the holding elements can be pivoted between their release position and their fixing position are preferably designed as horizontal pivot axes or pivot axes with a horizontal component to the central axis.
- the tensioning device can, for example, comprise a carriage guided in the base plate, which has a smaller distance to the central axis of the stand in the secured position than in its unlocked position. The force transmission device is thus pulled in the direction of the carriage when the carriage is transferred from the unlocked position into the safety position.
- the tensioning device can be designed as a tensioning ratchet known to those skilled in the art. According to the invention, there are no restrictions with regard to the design of the tensioning device.
- the power transmission device leads to all holding elements.
- the power transmission device can, for example, only comprise a tensioning cable which, starting from the tensioning device, leads to all the holding elements.
- one tensioning cable leads to one half of the holding elements, whereas the other tensioning cable leads to the other half of the holding elements.
- the force transmission device it is also conceivable for the force transmission device to have a number of force transmission elements corresponding to the number of retaining elements, for example in the form of tensioning cables, with each tensioning cable then leading to only a single retaining element.

- the stand is designed in such a way that the first plastic is polypropylene or acrylonitrile-butadiene-styrene copolymer and the second plastic is polyamide.
- the correspondingly designed stand is simple and inexpensive to manufacture and still has excellent stability. This is because the base plate can be produced together with the wall structure defining the receiving space, for example by means of injection molding, with the stabilizing component, which due to its material not being materially connectable to the wall structure and the base plate, being non-positively connected to the base plate by means of the guide device.
- the stand is preferably designed in such a way that the guide device is made of a metal, preferably made of steel.

- the guide device can be fastened to the base plate in that the part of the shank that has the external thread protrudes through an opening in the base plate and is fastened to the base plate by means of a fastening nut.
- the correspondingly designed stand has an even higher stability, since twisting of the guide device relative to the base plate and thus twisting of the stabilizing component relative to the base plate is avoided.
- the stand is designed in such a way that the guide device has a second eyelet in addition to the first eyelet includes, through which another end of the power transmission device is guided to the tensioning device.
- the stand is preferably designed in such a way that the eyelet of the guide device is a double eyelet, through which two ends of the force transmission device are guided to the tensioning device.
- the clamping device can be easily installed and removed in the stand and is nevertheless reliably connected to the stand.
- the force is transmitted from the clamping device directly to the stabilizing component of the stand.
- the correspondingly designed stand has an even higher stability, since the clamping device is prevented from being lifted out due to the counteracting force transmitted by the force transmission device.
- the stand is designed in such a way that only one force transmission element, preferably in the form of a tensioning cable, emanates from the tensioning device and leads to several, preferably all, holding elements, so that these can be placed on the outer circumference of a trunk or mast to be fixed, generating a uniform distribution of force.

Die Erfindung betrifft einen Ständer zum Aufspannen von mastoder stabförmigen Teilen, insbesondere zum Aufspannen von Christbäumen nach dem Oberbegriff des Anspruches 1.The invention relates to a stand for mounting mast or rod-shaped parts, in particular for mounting Christmas trees, according to the preamble of claim 1.
Ein gattungsbildender Ständer zum Aufspannen von mast- oder stammförmigen Teilen, insbesondere zum Aufspannen von Christbäumen ist beispielsweise aus der
Ein derartiger bekannter Ständer umfasst beispielsweise eine Bodenplatte, auf der Abstützeinrichtungen beispielsweise zum Halten eines Christbaumes vorgesehen sind. Diese Abstützeinrichtungen umfassen in der Regel mehrere um eine vertikale Zentralachse herum beabstandet angeordnete und um horizontale Achsen verschwenkbare Hebel oder Halteelemente, die im Wesentlichen auf die Zentralachse zu spannbar sind. Dabei werden die Spannkräfte über eine Spanneinrichtung aufgebracht.A known stand of this type comprises, for example, a base plate on which supporting devices are provided, for example for holding a Christmas tree. As a rule, these support devices comprise a plurality of levers or holding elements which are arranged spaced apart around a vertical central axis and can be pivoted around horizontal axes and which can essentially be clamped towards the central axis. The clamping forces are applied via a clamping device.
Dazu kann ein gattungsbildender Ständer einen zentralen Aufnahmeraum zum Einbringen des unteren Endes eines zu fixierenden Christbaumes aufweisen, wobei die gesamte Anordnung neben der Bodenplatte ein sich oberhalb der Bodenplatte erhebendes Gehäuse umfasst, und zwar mit der erwähnten zentralen Aufnahme zur Einführung eines zu fixierenden Baumstammes. Die bereits erwähnten und auf den Baumstamm zu verschwenkbaren Hebel ragen durch eine entsprechende Öffnung an der Oberseite der Gehäuseabdeckung heraus. Die von der Spanneinrichtung aufzubringenden Kräfte werden in eine Wandstruktur bzw. in eine Wandkontur eingeleitet.For this purpose, a generic stand can have a central receiving space for inserting the lower end of a Christmas tree to be fixed, with the entire arrangement next to the base plate comprising a housing rising above the base plate, specifically with the mentioned central receptacle for inserting a tree trunk to be fixed. The levers already mentioned and which can be pivoted onto the tree trunk protrude through a corresponding opening on the top of the housing cover. The forces to be applied by the clamping device are introduced into a wall structure or into a wall contour.

- einer Spanneinrichtung und einer flexiblen Kraftübertragungseinrichtung, die von der Spanneinrichtung zu den Halteelementen führt, wobei die Halteelemente mit der Spanneinrichtung mittels der Kraftübertragungseinrichtung bewegungsgekoppelt sind, wobei durch Überführen der Spanneinrichtung von einer Entsicherungsstellung in Richtung einer Sicherungsstellung die Kraftübertragungseinrichtung in einer Zugrichtung zu der Spanneinrichtung gezogen und/oder kraftbeaufschlagt wird, sodass die Spanneinrichtung mittels der Kraftübertragungseinrichtung einer Verschwenkung der Halteelement in Richtung Freigabestellung entgegenwirkt oder diese verhindert; und
- einer Führungseinrichtung, durch die mindestens ein Ende der Kraftübertragungseinrichtung zur Spanneinrichtung geführt ist, gelöst,
- der Ständer weist ein Stabilisierungsbauteil auf, das aus einem zweiten Werkstoff gebildet ist, der eine größere Festigkeit als der erste Werkstoff aufweist;
- das Stabilisierungsbauteil weist zumindest eine Durchgangsöffnung auf, durch die die Führungseinrichtung hindurchgeführt ist;
- die Führungseinrichtung ist mit der Bodenplatte verbunden, sodass das Stabilisierungsbauteil mit der Bodenplatte mittels der Führungseinrichtung unverrückbar verbunden ist; und
- die Spanneinrichtung steht mit dem Stabilisierungsbauteil in unmittelbaren Kontakt.
- a floor panel;
- an accommodation space which is arranged on the floor panel and is designed to accommodate a mast or rod-shaped part and which is formed by a wall structure formed from a first material;
- at least two holding elements adjoining the receiving space, which are arranged angularly offset around a central axis of the receiving space and can each be pivoted about a pivot axis away from the central axis in the direction of a release position and towards the central axis in the direction of a fixing position;
- a tensioning device and a flexible force transmission device, which leads from the tensioning device to the holding elements, the holding elements being movably coupled to the tensioning device by means of the force transmission device, the force transmission device being pulled in a pulling direction towards the tensioning device by transferring the tensioning device from an unlocking position in the direction of a securing position and /or force is applied, so that the tensioning device counteracts or prevents pivoting of the holding element in the direction of the release position by means of the force transmission device; and
- a guide device through which at least one end of the force transmission device is guided to the tensioning device,
- the stand has a stabilizing member formed of a second material having greater strength than the first material;
- the stabilizing component has at least one through-opening through which the guide device is guided;
- the guide device is connected to the base plate, so that the stabilizing component is immovably connected to the base plate by means of the guide device; and
- the clamping device is in direct contact with the stabilizing component.
Der erfindungsgemäße Ständer weist gegenüber bekannten Ständern eine erhöhte Stabilität auf, da eine von den Halteelementen über die Kraftübertragungseinrichtung auf die Spanneinrichtung übertragene Gegenkraft von dem Stabilisierungsbauteil aufgenommen wird. Folglich kann die den Aufnahmeraum definierende und diese umschließende Wandstruktur weniger stabil ausgebildet sein und beispielsweise aus einem dünneren und gegebenenfalls kostengünstigeren Material gefertigt sein. Aufgrund der Befestigung des Stabilisierungsbauteils an der Bodenplatte mittels der Führungseinrichtung ist der Ständer einfach und günstig herzustellen. So kann die Bodenplatte zusammen mit der Wandstruktur beispielsweise über ein Spritzgussverfahren hergestellt werden. Die Spanneinrichtung steht dabei in unmittelbarem Kontakt mit dem Stabilisierungsbauteil.Compared to known stands, the stand according to the invention has increased stability, since a counterforce transmitted from the holding elements to the tensioning device via the force transmission device is absorbed by the stabilizing component. Consequently, the recording space defining and this enclosing wall structure can be made less stable and can be made, for example, from a thinner and possibly more cost-effective material. Due to the fact that the stabilizing component is attached to the base plate by means of the guide device, the stand can be produced easily and inexpensively. For example, the base plate can be produced together with the wall structure using an injection molding process. The clamping device is in direct contact with the stabilizing component.
Über das Stabilisierungsbauteil wird die der Spannkraft der Spanneinrichtung entsprechende Reaktionskraft auf die Bodenplatte des Ständers übertragen.The reaction force corresponding to the clamping force of the clamping device is transmitted to the base plate of the stand via the stabilizing component.
Das Merkmal, gemäß dem der zweite Werkstoff eine größere Festigkeit als der erste Werkstoff aufweist ist so zu verstehen, dass bei gleichgeometrischen Werkstücken, die der gleichen Beanspruchung (Zug, Druck, Biegung, Scherung) ausgesetzt werden, ein Werkstück, das aus dem zweiten Werkstoff gebildet ist, eine größere Festigkeit aufweist als ein Werkstück, das aus dem ersten Werkstoff gebildet ist.The feature according to which the second material has greater strength than the first material is to be understood in such a way that in the case of workpieces of the same geometry that are subjected to the same stress (tension, pressure, bending, shearing), a workpiece made of the second material is formed has greater strength than a workpiece formed from the first material.
Die Schwenkachsen, um die die Halteelemente zwischen deren Freigabestellung und Fixierstellung verschwenkbar sind, sind vorzugsweise als horizontale Schwenkachsen oder Schwenkachsen mit einer horizontalen Komponente zur Zentralachse ausgebildet.The pivot axes about which the holding elements can be pivoted between their release position and their fixing position are preferably designed as horizontal pivot axes or pivot axes with a horizontal component to the central axis.
Die Spanneinrichtung kann beispielsweise einen in der Bodenplatte geführten Schlitten umfassen, der in der Sicherungsstellung einen kleineren Abstand zur Zentralachse des Ständers aufweist als in dessen Entsicherungsstellung. Somit wird die Kraftübertragungseinrichtung bei einem Überführen des Schlittens von der Entsicherungsstellung in die Sicherungsstellung in Richtung des Schlittens gezogen.The tensioning device can, for example, comprise a carriage guided in the base plate, which has a smaller distance to the central axis of the stand in the secured position than in its unlocked position. The force transmission device is thus pulled in the direction of the carriage when the carriage is transferred from the unlocked position into the safety position.
Anstelle des Schlittens kann aber beispielsweise auch eine vorgespannte Rolle zum Auf- und Abrollen der Kraftübertragungseinrichtung vorgesehen sein. Somit kann die Spanneinrichtung als dem Fachmann bekannte Spannratsche ausgebildet sein. Beschränkungen hinsichtlich der Ausgestaltung der Spanneinrichtung bestehen erfindungsgemäß keine.Instead of the carriage, however, a prestressed roller for winding and unwinding the force transmission device can also be provided, for example. Thus, the tensioning device can be designed as a tensioning ratchet known to those skilled in the art. According to the invention, there are no restrictions with regard to the design of the tensioning device.
Die Kraftübertragungseinrichtung führt zu allen Halteelementen. Je nach Ausführung kann die Kraftübertragungseinrichtung beispielsweise lediglich ein Spannseil umfassen, das ausgehend von der Spanneinrichtung zu sämtlichen Halteelementen führt. Bei einer Ausgestaltung der Kraftübertragungseinrichtung mit zwei Spannseilen führt das eine Spannseil zu der einen Hälfte der Halteelemente, wohingegen das andere Spannseil zu der anderen Hälfte der Halteelemente führt. Es ist jedoch auch denkbar, dass die Kraftübertragungseinrichtung eine der Anzahl der Haltelemente entsprechende Anzahl von Kraftübertragungselementen beispielsweise in Form von Spannseilen aufweist, wobei dann jedes Spannseil jeweils zu lediglich einem einzigen Halteelement führt.The power transmission device leads to all holding elements. Depending on the design, the power transmission device can, for example, only comprise a tensioning cable which, starting from the tensioning device, leads to all the holding elements. In an embodiment of the power transmission device with two tensioning cables, one tensioning cable leads to one half of the holding elements, whereas the other tensioning cable leads to the other half of the holding elements. However, it is also conceivable for the force transmission device to have a number of force transmission elements corresponding to the number of retaining elements, for example in the form of tensioning cables, with each tensioning cable then leading to only a single retaining element.
Die Verbindung der Führungseinrichtung mit der Bodenplatte erfolgt vorzugsweise durch eine Verschraubung, indem zumindest ein endseitiger und aus der Bodenplatte herausragender Gewindeabschnitt der Führungseirichtung mittels einer Befestigungsschraube an der Bodenplatte verbunden ist.The guide device is preferably connected to the base plate by means of a screw connection, in that at least one threaded section of the guide device at the end and protruding from the base plate is connected to the base plate by means of a fastening screw.
Vorzugsweise ist der Ständer derart ausgebildet, dass das Stabilisierungsbauteil mit der Wandstruktur und/oder mit der Bodenplatte formschlüssig verbunden ist.The stand is preferably designed in such a way that the stabilizing component is positively connected to the wall structure and/or to the base plate.
Der entsprechend ausgebildete Ständer weist eine nochmals größere Stabilität auf. Vorzugsweise ist das Stabilisierungsbauteil von der Wandstruktur und/oder der Bodenplatte umspritzt. Vorzugsweise ist der Ständer derart ausgebildet, dass das Stabilisierungsbauteil mit der den Aufnahmeraum bildenden Wandstruktur in unmittelbaren Kontakt steht.The correspondingly designed stand has even greater stability. Preferably, the wall structure and/or the base plate is injection-molded around the stabilizing component. The stand is preferably designed in such a way that the stabilizing component is in direct contact with the wall structure forming the receiving space.
Weiter vorzugsweise ist der Ständer derart ausgebildet, dass der erste Werkstoff ein erster Kunststoff und der zweite Werkstoff ein zweiter Kunststoff ist.More preferably, the stand is designed in such a way that the first material is a first plastic and the second material is a second plastic.

Aus den
Aus den Figuren ist ersichtlich, dass der Ständer 1 eine Bodenplatte 10 und eine mit der Bodenplatte 10 integral ausgebildete Wandstruktur 20 aufweist. Die Wandstruktur 20 umschließt dabei einen Aufnahmeraum 30, in den das zu fixierende mast- oder stabförmige Teil eingesetzt werden kann. Aus den Figuren ist ferner ersichtlich, dass der in dem Ausführungsbeispiel dargestellte Ständer 1 vier Halteelemente 40 aufweist, die um eine Zentralachse des Aufnahmeraumes 30 herum winkelversetzt angeordnet sind. Jedes der Halteelemente 40 ist dabei um eine Schwenkachse von der Zentralachse weg in Richtung einer Freigabestellung und auf die Zentralachse zu in Richtung einer Fixierstellung verschwenkbar. In dem dargestellten Zustand des Ständers befinden sich die Halteelemente 40 jeweils in ihrer Fixierstellung.It can be seen from the figures that the stand 1 has a
Der Ständer 1 weist ferner eine Spanneinrichtung 60 und eine in den Figuren nicht dargestellte Kraftübertragungseinrichtung auf. Bei der Spanneinrichtung 60 handelt es sich um eine fußbetätigbare Spanneinrichtung 60, die einen Ratschenmechanismus verwendet, wobei auf einer Spannwelle der Spanneinrichtung 60 die Kraftübertragungseinrichtung, die üblicherweise in Form eines Spannseils ausgebildet ist, aufwickelbar ist.The stand 1 also has a
Die Spanneinrichtung in Form des Spannseils führt von der Spanneinrichtung 60 zu den jeweiligen Halteelementen 40, sodass die Halteelemente 40 mit der Spanneinrichtung 60 mittels des Spannseils bewegungsgekoppelt sind. Hierzu weisen die Halteelemente 40 jeweils Durchgangsöffnungen 41 auf, durch die das Spannseil hindurchgeführt ist. Durch Überführen der Spanneinrichtung 60, im Genaueren des Spannhebels 61 der Spanneinrichtung 60, von einer Entsicherungsstellung in Richtung einer Sicherungsstellung wird das Spannseil in einer Zugrichtung zu der Spanneinrichtung 60 gezogen bzw. kraftbeaufschlagt, sodass die Spanneinrichtung 60 mittels der Spannseils einer Verschwenkung der Halteelemente 40 in Richtung deren Freigabestellung entgegenwirkt oder diese gar verhindert. Aus den Figuren ist weiter ersichtlich, dass der erfindungsgemäße Ständer eine Führungseinrichtung 70 aufweist, durch die die jeweiligen Enden des Spannseils zu der Spanneinrichtung 60 geführt sind.The tensioning device in the form of the tensioning cable leads from the
Mit Bezug auf die

Wie insbesondere aus
Folglich ermöglicht der erfindungsgemäße Ständer, dass beispielsweise die Wandstruktur 20 und auch die Bodenplatte 10 aus einem ersten Material, beispielsweise einem ersten Kunststoff gebildet ist, der eine verhältnismäßig niedrigere Festigkeit aufweist als der zweite Werkstoff, insbesondere der zweite Kunststoff, aus dem das Stabilisierungsbauteil 80 gebildet ist.Consequently, the stand according to the invention makes it possible for example for the
Auch die Niederhalteeinrichtung 90 weist eine erste Durchgangsöffnung 91 und eine zweite Durchgangsöffnung 92 auf, durch die der erste Schaft 71 bzw. der zweite Schaft 72 der Führungseinrichtung 70 hindurchgeführt sind.The hold-down
Wie insbesondere aus
Die Reaktionskraft, die der durch die Spanneinrichtung 60 erzeugten Spannkraft entspricht, weist sowohl eine horizontale Kraftkomponente als auch eine vertikale Kraftkomponente auf. Die horizontale Kraftkomponente drückt die Spanneinrichtung 60 in Richtung des Stabilisierungsbauteils 80 und die vertikale Kraftkomponente drückt die Spanneinrichtung 60 vertikal nach oben aus der Aufnahme 83 heraus. Um ein heraushebender Spanneinrichtung 60 aus der Aufnahme 83 zu verhindern, ist zwischen der Führungseinrichtung 70 und dem Stabilisierungsbauteil 80 die Niederhalteeinrichtung 90 in Form einer Platte 90 vorgesehen.The reaction force, which corresponds to the clamping force generated by the clamping
Ein Haltesteg 93 der Niederhalteeinrichtung 90 ragt in die Aufnahme 83 des Stabilisierungsbauteils 80 hinein bzw. ragt über die Flanschabschnitte 63 der Spanneinrichtung 60 hinaus. Die Niederhalteeinrichtung 90 steht dabei mit den Flanschabschnitten 63 der Spanneinrichtung 60 in direktem Kontakt, sodass die Niederhalteeinrichtung 90 ein Herausheben der Spanneinrichtung 460 aus der Aufnahme 83 des Stabilisierungsbauteils 80 verhindert. Die Niederhalteeinrichtung 90 wird von oben durch die Öse 73, 74 gehalten und ist von den Schäften 71, 72 durchsetzt. Die Schäfte 71, 72 sind wie bereits oben erwähnt an der Bodenplatte 10 des Ständers 1 befestigt, sodass ein Herausheben der Niederhalteeinrichtung 90 nicht möglich ist.A holding
