Definitions
- DE-GM 6918214 describes a Christmas tree stand with a receiving sleeve which has resilient projections with axially parallel resilient teeth at the upper end distributed around the circumference.
- a clamping sleeve with an inward constriction presses the teeth inward over an inclined surface and thus fixes the trunk.
- the receptacle is inserted in a pot-shaped container, on the bottom of which an upright, pointed pin ensures that the trunk end is fixed.
- the container for keeping the Christmas tree fresh can be filled with water.
- the stem is determined by screwing on the adapter sleeve by a movement of the teeth determined by the incline on the inside thereof.
- DE 4118695 A1 specifies a device for holding one end of a rod-shaped structure, which also serves to remove the trunk of a
- the device has a sleeve, on the inner wall of which an externally refillable body made of rubber-elastic material is attached. After filling with a gaseous or liquid medium, the inside of the body wraps around the trunk of the Christmas tree and holds it in place.
- the device has the disadvantage that the tree trunk to be locked cannot be aligned in the vertical position. Likewise, a subsequent inclination of the Christmas tree cannot be avoided, since this device has no rigid and thus lockable elements. When tilted, the Christmas tree to be locked cannot be brought into the desired vertical position by means of specifically detectable forces and permanently fixed.
- a Christmas tree stand in which, in a hemispherical housing, arc-shaped actuators hold the trunk of the Christmas tree.
- the individual actuators are guided in channels which are provided in a sleeve mounted in the interior of the housing and are held in their open positions by a spring.
- a holder At the bottom of the sleeve there is a holder for guiding the trunk end.
- the ends of the actuators facing away from the Christmas tree stand on foot plates on the floor of the surrounding space and thus form the foot part of the known Christmas tree stand.
- the uniform attack of the actuators depends both on whether the floor of the installation space forms a flat surface and on the fact that the trunk of the Christmas tree has an exact cylindrical cross-section at the level of the points of attack. The latter is not the case with normal trees, rather sawn-off branch stubs on the trunk must be expected.
- the well-known Christmas tree stand is also not suitable for placing trees on streets and squares due to the unevenness of the floor. Another disadvantage is that slender, relatively light trees are found with lower forces than densely overgrown trees of the same height.
- the object of the invention is seen in the creation of a Christmas tree stand, with which the Christmas tree can be determined reliably and without play on all sides, regardless of the nature of the floor at the installation site, even with a non-uniform design of the surface of the trunk.
- Figure 1 sectional view of the Christmas tree stand according to the invention with a locking bell with inserted Christmas tree and filled bellows
- Figure 2 as Figure 1, but without a Christmas tree and with the bellows empty;
- FIG. 3 Christmas tree stand with two locking bells
- Figure 4 top view of Figure 2
- Figure 5 Representation of the upper and lower locking elements in the open or closed state
- Figure 6 Side view of an upper locking element with locking screw

- Figure 9 Christmas tree stand of low overall height
- Figure 10 locking element; Side view
- Figure 11 Section A-B to Figure 10.
- the locking elements 4 are mounted according to Figures 1 and 2 movable about a vertical axis A. In the case of a horizontal-vertical movement, they are subjected to an arc at the end in the upwardly open locking bell 3 a by the annular bellows 16 in such a way that they first adapt to the bellows 16, which increases in volume. If the bellows 16 is then filled further, the locking elements 4 are pushed in the direction of expansion of the expanding bellows 16. With this displacement, the locking elements 4 move in a horizontal-vertical manner in the direction of the vertical axis A. This movement takes place by applying the locking elements 4 on the inside of the locking bell 3 a, with individual or all locking elements 4 following in the locking bell 3 Align the incorporated guide slots 35.
- the individual locking elements 4 initially attach to the peripheral surface of the Christmas tree 17 in such a way that no or only an insignificant holding force is exerted thereon. It is irrelevant how the circumferential surface to be clamped is designed in its contour, since the individual locking elements 4 adapt to it.
- the individual locking elements 4 are pressed in accordance with the pressure increase in the bellows 16 both on the inside of the locking bell 3 a and on the peripheral surface of the Christmas tree.
- the individual locking elements 4 do not move or only move completely insignificant. This has the advantage that the Christmas tree to be determined is not pushed out of its predetermined vertical position. If the pressure in the bellows 16 has been increased only slightly or insignificantly, the Christmas tree to be locked can still be aligned in its vertical position, since the holding forces that occur on the friction surface between the locking elements 4 and the locking bell 3 a correspond relatively easily to the pressure exerted can be overcome. With this alignment, the individual locking elements 4 remain largely unchanged on the circumferential surface of the Christmas tree 17.
- the trunk is aligned by moving the individual locking elements 4 on the locking bell 3 a.
- the desired position of the Christmas tree is achieved by simply tilting the trunk.
- the centering dome 20 attached to the stand base 18 serves as a fixing point.
- the individual locking elements 4 are either adjusted from the bellows 16 in the direction of the axis A or pushed back in the direction of the bellows 16 by the forces applied to the tree trunk. During the alignment process, all locking elements 4 remain in contact with the trunk to be locked.
- the Christmas tree 17 is finally fixed and locked, the individual locking elements 4 being attached to both the object to be locked and the inside of the locking bell 3 a.
- the Christmas tree 17 is held immovably.
- a supply line 49 which is closed off by a valve, is provided for filling the bellows 16 with a pressure medium.
- any shrinkage of the detected Christmas tree 17 in the contact area of the locking elements 4 is automatically compensated for here. This ensures a secure and permanent detection.
- the locking screws 37 incorporated in at least three of the locking elements 4 according to FIG. 6 and FIG. 7, which pass through the guide slots 35 of the locking bell 3 a and on which a suitable locking nut 39 with a washer is screwed on the Christmas tree to be held can additionally be tightened by tightening the locking nuts 39 be secured mechanically and permanently at the lateral edges of the guide slots 35. This additional mechanical protection increases the stability of the Christmas tree significantly and permanently.
- the locking screws 37 located on the outside of the locking bell 3 a can be actuated easily and, when loosening the Christmas tree, advantageously serve to loosen the locking elements 4 after the bellows 16 has been emptied and to reset them in the direction of the bellows 16.
- FIG. 4 shows a possible arrangement of the guide slots 35 in the locking bell 3 a and the position of the filling and emptying openings 46 and 47 for filling the stand base 2 with water.
- elastic elements 48 are inserted between the locking elements 4 according to FIG. 5, which effect a uniform distribution of the same in the open state (FIG. 5, bottom left) and support their return from the determination of the Christmas tree 17 after the pressure medium has been released (Figure 5, bottom right).
- the elastic elements 48 can each be inserted into a lateral recess 54 of two adjacent fixing elements 4 or partially enclose them.
- FIG. 3 Another embodiment within the scope of the inventive concept is given in FIG. 3.
- the lower end of the trunk of the Christmas tree 17 is not by a fixing mandrel, but by a mirror image arranged in the lower
- Locking bell 3 b installed sequence of further locking elements 22 aligned and fixed. The latter are also acted upon at the end by the common bellows 16, they come into contact with the trunk through the slots 50 provided in the receiving part 19.
- On the left side of Figure 3 is the provision of the locking elements 4 and 22 when the bellows 16 is empty and on the right side
- the locking elements 4 and 22 are aligned at low pressure until the stem touches; the movements take place in the opposite direction.
- the pressure in the bellows 16 is further increased, the Christmas tree is finally fixed and locked, the individual locking elements 4 and 22, with increased pressure, being supported both on the object to be locked and on top and bottom of the inside of the locking bell 3 a and 3 b on.
- the Christmas tree is held firmly. Any shrinkage of the Christmas tree found in the contact area of the locking elements 4 or 22 is also automatically compensated for here. This ensures a secure and permanent detection.
- the lower Locking elements 22 can also be advantageously equipped with elastic elements 48.
- the feed line 49 for the bellows 16 is guided in the parting plane between the locking bell 3 a and the stand base 2 (FIG. 1) or the locking bell 3 b (FIG. 3).
- a Christmas tree stand with two separate locking systems according to FIG. 8 is provided for use with particularly tall Christmas trees.
- This construction has an upper row of locking elements 4 loaded with the first bellows 16 a in the locking bell 3 a and a lower row of locking elements 22 loaded with the second bellows 16 b in the locking bell 3 b.
- the total height H of the Christmas tree stand is also determined by the intermediate piece 53 inserted between the two locking bells 3 a and 3 b, which is supported on the stand base 2.
- the receiving part 19 attached inside is extended by the height of the intermediate piece 53.
- Each of the bellows 16 a, 16 b is connected to a separate supply line 49 via a valve, not shown, with a pressure medium supply.
- the other details of this embodiment correspond to the construction according to FIG. 3.
- the position of FIG. 8 is also on the left side
- Locking elements 4 and 22 shown with empty bellows 16 a, 16 b and on the right side with the Christmas tree 17 clamped.
- the construction according to FIG. 8 is particularly suitable for tall Christmas trees to be set up outdoors.
- the separate, independent assignment of a bellows 16 a or 16 b to each of the two locking systems also allows the use of comparatively high spacers 53 and thus the use of large clamping moments.
- a further increase in stability is possible by using a metal for the stand base 2 and for the base plate 18.
- a further advantage of the embodiment according to FIG. 8 lies in the separate setting of the lower and the upper locking elements 4 and 22.
- the method used in the Christmas tree stand according to FIG targeted, independent application of the locking elements 4 and 22 are significantly improved and accelerated.
- the idea of the invention can also be used successfully in another, particularly simple embodiment of the Christmas tree stand with a low overall height.
- the housing is designed according to FIG. 9 as a one-piece molding 103, in which the upper part 102 merges directly into the foot part 101.
- the upper part 102 does not form a complete hemisphere, but a spherical section with a central angle of less than 180 degrees, which makes a decisive contribution to reducing the overall height.
- an annular shell 105 is attached, which serves as a guide for the trunk of the Christmas tree 17 and as an abutment for the bellows 16.
- the receiving sleeve 106 which supports the Christmas tree 17 and which is used as a water container, is inserted into the ring shell 105.
- the centering mandrel 20 At the bottom of the receiving sleeve 106 is the centering mandrel 20, which has the same task as in the embodiment according to FIGS. 1 and 2.
- the Christmas tree stand with the bellows 16 empty is shown on the left side of FIG. 9, while the right side shows the stand with an inserted Christmas tree 17.
- the arcuate locking elements 104 are provided, which are acted upon by a bellows 16 on their end side, as in the embodiments already described.
- the lateral guidance of the locking elements 104 takes place by means of the ribs 110 fastened to the upper part 102, which engage in correspondingly designed grooves 111 of the locking elements 104.
- guide slots 35 are also provided in the upper part 102 according to FIG.
- a base plate 18 is fastened to the underside of the foot part 101 of the Christmas tree stand according to FIG. 9, on which both the ring shell 105 and the receiving sleeve 106 are supported. The fastening is done by screw connections, but it can also be carried out with the help of plug connections, since there are no requirements for tightness.

- the pipe connection 119 is laid in the area of the Christmas tree stand in the vicinity of the base plate 18 and is guided on the underside of the ring shell 105 and through the side wall of the shaped piece 103.
- Air or a non-combustible gas such as nitrogen can be used as pressure medium for filling the bellows 16, 16 a and 16 b for all designs.
- An inert gas such as helium can also be used in particularly vulnerable rooms.
- the filling pressure indicated by a manometer is controlled by hand using a simple valve.
- a liquid can also be used as the pressure medium, which is connected via the feed line 49 to an externally arranged pressure medium reservoir and can also be controlled as a function of pressure.
- This control can also take place with an automatic control device that is set to maintain a certain pressure value.
- locking elements 104 can be provided for installation in the locking bell 3 a or in the upper part 102 of the shaped piece 103, which, according to FIGS. 10 and 11, have a circumferential edge 115 on the circumference, which on the inner surface the side facing the spherical section is interrupted by a groove 111, which in each case engages with a rib 110 (FIG. 9) extending in the adjustment direction.
