Christmas tree stand

The innovation relates to a Christmas tree stand according to the generic term protection claim 1.

The aim of the innovation is to present a Christmas tree stand that is characterized by a particularly simple and yet reliable handling. To solve this problem, a Christmas tree stand is designed in accordance with protection claim 1.

In the new Christmas tree stand, the swivel jaws can be swiveled around axes parallel to the axis of the holder. This makes it possible to design the swivel jaws in such a way that their clamping surface extends over the entire height of the swivel jaws, whereby when the Christmas tree or tree trunk is clamped, the swivel jaws rest against the trunk over their entire height, thus achieving a large-area clamping over a sufficient axial length, so that additional fixing means, such as a mandrel for the end of the trunk, can be dispensed with.

Further developments of the innovation are the subject of the dependent claims.

The invention is explained in more detail below using the figures as an example. They show:

Fig. 1 in simplified representation and in plan view a Christmas tree stand according to

the innovation;
Fig. 2 shows a simplified section along line ll of Fig. 1.

The Christmas tree stand, generally shown with 1 in the figures, consists essentially of a base or base plate 2 which forms the standing surface and which, in the embodiment shown, is designed in the shape of a circular disk and at whose

A pipe section 3 is attached to the top side, which is arranged on the same axis as the base plate 2 and forms a receptacle. Three swivel jaws 4, 4' and 4" are provided on the pipe section 3, offset at equal angular intervals around the central axis, each of which can be swiveled about an axis parallel to the axis of the pipe section, by means of hinge pins 5 which are attached to the outside of the pipe section at both ends, to the base plate 2 or to the latter. The swivel jaws 4, 4' and 4" can each be swiveled from a position outside the pipe section 3 into positions in which the jaws extend radially into the interior of the pipe section 3 through openings 6, in order to clamp the trunk 7 of a Christmas tree (not shown in detail otherwise).

In the embodiment shown, the swivel jaws 4 are each provided with a contact or clamping surface 8, which in the embodiment shown is designed as part of a circular cylindrical surface, specifically around an imaginary cylinder axis that is parallel to the axis of the respective hinge pin 5, but is radially offset from this axis. In the embodiment shown, the swivel jaws 4 are also flat on their rear side facing away from the clamping surface 8. The hinge pins 5 are located at the transition between this flat surface 9 and the clamping surface 8. A rope-like clamping element 10 is provided for clamping the trunk 7 between the swivel jaws 4, 4' and 4", which forms two lengths 10' and 10" on both sides of a clamping device 11, specifically outside the pipe section 3. One length 10' is guided from the clamping device 11 over the swivel jaw 4 adjacent in a circumferential direction of the pipe section 3 and is attached with its other end to the swivel jaw 4' following the swivel jaw 4 in the same circumferential direction, specifically on the side of this swivel jaw that is remote from the hinge pin 5. The other length 10" is connected at one end to the clamping device 11 and at the other end to the swivel jaw 4" adjacent to the clamping device 11 in the other circumferential direction of the pipe section 3, again with the side remote from the hinge pin 5. The clamping device 11 is provided fixedly on the base plate 2.

In the embodiment shown and in the representation chosen for Fig. 1, the swivel jaws 4 - 4" are designed in such a way that the two swivel jaws 4 and 4' each swivel from the rest or starting position into the clamping position, in which the clamping surfaces 9 extend through the openings 6 into the interior of the pipe section 3, in an anti-clockwise direction about their hinge pins 5, while the swivel jaw 4" swivels in the opposite direction, i.e. clockwise, from the starting position into the clamping or tensioning position.

The clamping device is only shown very schematically in Fig. 1. Spindle devices that enable the lengths 10' and 10" to be clamped simultaneously are particularly suitable as clamping devices.

The described design enables at least the clamping jaws 4 and 4' to move to different degrees during clamping, so that an optimal fit of all clamping jaws 4 - 4" against the trunk 7 is ensured after clamping.

The clamping jaws 4 - 4" or their clamping surfaces 8 have a considerable height in the axial direction of the articulated bolts 5, which in the embodiment shown is greater than half the diameter of the pipe section 3, so that the respective trunk 7 is clamped by the swivel jaws 4 - 4" over a sufficient axial length and thus additional means for fixing the lower end of the trunk 7 in the receptacle formed by the pipe section 3, for example in the form of a dome to be pressed into the trunk 7, etc., can be dispensed with.

The swivel jaw 4 can also be rounded on its rear side.

Claims (5)

Protection claims 1. Christmas tree stand with a receptacle provided on a base or base plate (2) for inserting a tree trunk (7) and with a plurality of pivoting jaws (4 - 4") distributed along the receptacle, which can be moved by means of a common clamping element (10) from an initial position into a clamping position in which the pivoting jaws (4 - 4") each bear against the tree trunk (7) with a clamping surface (8), characterized in that the pivoting jaws (4 - 4") can each pivot about an axis parallel to the axis of the receptacle (3). 2. Christmas tree stand according to claim 1, characterized in that the pivoting jaws (4 - 4") each have a clamping surface (8) which runs spirally to the pivot axis. 3. Christmas tree stand according to one of the preceding claims, characterized in that the pivoting jaws (4 - 4") each have a clamping surface (8) which is circular-cylindrical or approximately circular-cylindrical around an imaginary axis which is parallel to the pivot axis but is radially offset from it. 4. Christmas tree stand according to one of the preceding claims, characterized in that the tensioning element is a band-shaped or chain-like element. 5. Christmas tree stand according to one of the preceding claims, characterized in that the clamping surfaces (8) of the pivoting jaws (4 - 4") have a height in the axial direction of the holder (3) which is at least equal to half the diameter of the holder (3).
