Description

Die Erfindung betrifft einen Ständer gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a stand according to the preamble of patent claim 1.

Bei einem derartigen, in der DE 195 14 899 A1 beschriebenen Ständer, insbesondere Christbaumständer, ist die Verstelleinrichtung als Scheibe ausgebildet, die auf ihrer Oberseite mit einer Spiralnut versehen ist, in die die an der Unterseite von Klemmbacken angebrachten Zahnstangen eingreifen. Der rotatorische Antrieb der Spiralnutscheibe erfolgt mittels eines von Hand antreibbaren Zahnritzels, das in eine am Außenumfang der Scheibe angebrachte Verzahnung eingreift. Wenn die Spiralnutscheibe in Drehung versetzt wird, werden die Klemmbacken mittels ihrer in die Spiralnut eingreifenden Zahnstangen entweder nach innen zum Festklemmen des zylindrischen Profils oder nach außen zum Freigeben dieses Profils verschoben. Die Spiralscheibe und die Klemmbacken mit den daran angebrachten Zahnstangen sind in einem im Fußteil allseitig schwenkbar gelagerten Einbau gelagert, der mittels einer einen Metallspannring umfassenden Spannvorrichtung innerhalb einer Umfangswand des Fußteils festklemmbar ist. Dieser bekannte Ständer besteht in nachteiliger Weise aus einer Vielzahl von Einzelteilen. Dadurch, daß die Klemmbacken oberhalb der Spiralnutscheibe angeordnet sind, ergibt sich auch eine relativ große Bauhöhe des Ständers. Obwohl eine Befüllung des Ständers mit Wasser zur Versorgung eines Christbaums vorgesehen ist, ist es weiterhin nachteilig, daß der oberhalb der Spiralnutscheibe abgestützte Christbaumstamm nur dann mit Wasser versorgt wird, wenn die Wasserfüllung ein relativ hohes Füllniveau hat.With such a stand, described in DE 195 14 899 A1, in particular Christmas tree stand, the adjustment device is designed as a disc on its top is provided with a spiral groove into which those attached to the underside of clamping jaws Engage the racks. The spiral grooved disc is driven in rotation by means of a toothed pinion which can be driven by hand and which is located on the outer circumference of the disk attached toothing engages. When the spiral grooved disc is rotated, the jaws either by means of their toothed racks engaging in the spiral groove inwards for clamping the cylindrical profile or outwards for releasing moved this profile. The spiral washer and the jaws with the attached ones Racks are installed in a swivel-mounted installation in the foot section stored within a clamping device comprising a metal clamping ring a peripheral wall of the foot part can be clamped. This known stand consists of disadvantageously from a variety of items. Because the jaws Are arranged above the spiral grooved disc, there is also a relatively large height of the stand. Although filling the stand with water to supply a Christmas tree is provided, it is also disadvantageous that the above the spiral grooved washer supported tree trunk is only supplied with water if the Water filling has a relatively high level.

Der Erfindung liegt die Aufgabe zugrunde, einen mit weniger Einzelteilen ausgerüsteten Ständer zu schaffen, der neben einer geringeren Bauhöhe auch dann eine Versorgung des Christbaumes mit Wasser gewährleistet, wenn dieses in dem Ständer nur eine sehr geringe Füllhöhe hat.The invention has for its object a one equipped with fewer items To create stands that, in addition to a lower overall height, then also supply the Christmas tree guaranteed with water if this in the stand only a very small Level.

Durch die Anordnung der mit Zahnstangen versehehenen Klemmbacken unterhalb der mit der Spiralnut versehenen Verstelleinrichtung angeordnet sind, verringert sich die Bauhöhe des Ständers. Da die Verstelleinrichtung ein Stellring ist, kann das zylindrische Profil, insbesondere ein Christbaumstamm, durch diesen Stellring bis zum Boden des Fußteils hindurch gesteckt werden, so daß auch bei einem sehr niedrigen Wasserstand in dem Fußteil eine ausreichende Versorgung des Stammes mit Wasser gewährleistet ist.By arranging the jaws provided with racks below the the spiral groove provided adjusting device, the overall height is reduced of the stand. Since the adjusting device is an adjusting ring, the cylindrical profile, in particular a Christmas tree trunk, through this collar to the bottom of the foot section be plugged so that even at a very low water level in the foot part an adequate supply of water to the trunk is guaranteed.

Weitere Ausgestaltungen der Erfindung sind in den Unteransprüchen behandelt.Further embodiments of the invention are dealt with in the subclaims.

  • FIG. 2 shows a top view,
  • FIG. 3 shows a bottom view of the adjusting ring provided with a spiral groove.

    • Figur 1 zeigt das Fußteil 1 des erfindungsgemäßen Ständers mit dem im wesentlichen ringförmigen Aufnahmeteil 2 zum Einsetzen des Pfostens bzw. Baumstammes. Gemäß Figur 2 sind drei Haltelemente 3 vorgesehen, die in Richtung der Doppelpfeile f1 in radialer Richtung verstellbar sind. Jedes Haltelement 3 hat im wesentlichen die Form eines Balkens 3.1, der in einer an dem Aufnahmeteil 2 angebrachten Führung 4 geführt ist. An der Oberseite des Balkens 3.1 ist eine Verzahnung in Form einer radial ausgerichteten Zahnstange 3.2 angebracht. Am vorderen Ende des Balkens 3.1 ist ein Klemmorgan, beispielsweise in Form einer Klemm- bzw. Spannbacke 3.3 angebracht, die gegen einen in das Aufnahmeteil 2 eingesetzten Stamm bzw. Pfosten zur Anlage gebracht werden kann. Die Ausgestaltung des Klemmorgans ist für den Erfindungsgegenstand unerheblich.Figure 1 shows the foot part 1 of the stand according to the invention with the substantially annular Receiving part 2 for inserting the post or tree trunk. According to FIG. 2 three holding elements 3 are provided, which in the direction of the double arrows f1 in the radial direction are adjustable. Each holding element 3 has essentially the shape of a bar 3.1, which is guided in a guide 4 attached to the receiving part 2. At the top the beam 3.1 is a toothing in the form of a radially aligned rack 3.2 appropriate. At the front end of the bar 3.1 is a clamping member, for example in Form of a clamping or clamping jaw 3.3 attached against one in the receiving part 2 used stem or post can be brought to the plant. The design the clamping member is irrelevant to the subject of the invention.

    Auf der Oberseite des Aufnahmeteils 2 ist zum Verstellen der Halteelemente ein Stellring 5 gelagert, der, wie insbesondere in Figur 3 dargestellt, an seiner Unterseite mit einer Spiralnut 5.1 versehen ist. Der Stellring 5 ist an seinem Außenumfang mit einer Zahnritzel 5.2 versehen, in den ein Zahnritzel 8 eingreift, das auf der Abtriebswelle 7 eines Elektromotors 6 gelagert ist, derart, daß mittels des Elektromotors 6 der Stellring 5 in der einen oder der anderen Richtung gedreht werden kann.On the top of the receiving part 2 is an adjusting ring for adjusting the holding elements 5 mounted, which, as shown in particular in Figure 3, on its underside with a spiral groove 5.1 is provided.
