    Christmas tree
    BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a Christmas tree foot comprising a holder part attachable to the lower end of the stem of a Christmas tree, and a standard part where a ball joint between the holder part and the standard part is lockable in a fixed angular position between the holder part and the standard part. with an inner ball shell surface, and to the standard part is coupled an inner ball shell with an outer ball shell surface, the outer ball shell having a cut-through and a through-cut slot from an outer surface and through the inner ball shell surface.
    From German utility model DE 29617240 U1 a Christmas tree foot is known. According to the specification, the holder part and the outer ball shell are formed in one and the same element, so that the stresses the element is exposed to during mounting on the inner ball shell belonging to the holder part becomes unnecessarily large. It is an object of the invention to provide a Christmas tree foot in which the outer pellets are easily deformed without being subjected to high stresses.
    The object of the invention is met by a Christmas tree foot of the type set forth in the preamble of claim 1, which is characteristic of a locking screws inserted in the radially extending threaded ring which extends in the radially extending threaded holes and adapted to pressurize the outer sleeve by tightening in the radially extending threaded holes. against the inner ball shell while reducing the slot for locking the outer ball shell against the inner ball shell.
    The locking screws are thus pressed inwardly against the outer ball shell which gives in to the pressure due to the through gap, whereby the outer ball shell is pressed inwards and comes into contact with the inner
    DK 2016 70355 A1 bullet shell. By further tightening the locking screws, a firm grip can be established between the inner and outer ball shells as the clamping ring absorbs the resulting tensioning stresses therein. It should further be noted that the outer ball shell slot mounted in this tension ring is concealed by this construction so that it is partly kept free from the build-up of dirt pavements and partly not visible.
    As set forth in claim 2, the holder comprises a tube having a first and a second end and having an inner and outer circumference and a thickness, and wherein the outer ball shell is inserted and axially retained at the first end of the tube, the first end of the tube thereby forming it. extending tension around the outer ball shell and wherein at the other end of the tube are provided several radially extending threaded holes with inserted retaining screws arranged to engage a lower stem portion of a Christmas tree. When the outer ball shell is merely axially retained in the tube, it is ensured that the ball shell can move inward without the tube itself having to move, and with the tension ring formed as a lower part of the tube, which at the same time holds the Christmas tree, a very simple construction is obtained.
    As stated in claim 3, it is preferred that the outer ball shell is axially secured to the tube by means of locking rings inserted in circular grooves. This provides an axial restraint which is achievable with readily available means, and it also becomes easy to remove the ball head from the tube.
    According to claim 4, the standard portion comprises a base having a bottom side having one or more supporting points in the same plane, at least three supporting points being evenly distributed along a circle, the supporting points communicating with a central area at the center of the circle via connecting members, at the central region is a mount and where the outer ball shell is mounted on the mount, so that the outer ball shell of the holder part encloses the inner ball shell and is angled and fastened thereto without a
    The lower edge of the cylindrical tube of the holder collides with the floor or the connecting parts between the support points and the central area. Such a stand may, for example, be constituted by a circular disc of metal. Here, the support points will in fact be an infinity of support points, and the connection between the support points and the central area is simply made of unbroken disc material. But there is a great variety of possible designs of such a standard part. The mounting is necessary if a significant angular rotation between the holder part and the standard part is desired, and it is therefore the height of the mounting above the floor or the connecting part between supporting points and the floor that helps to determine how much the holder is allowed to turn angle before collision between the parts.
    As stated in claim 5, it is preferred that the inner and outer spherical shells each extend in both directions away from an equatorial plane and are limited by bounding planes parallel to the equatorial plane where the outer sphere shells in the tube are mounted with the center of the equatorial shaft running parallel to the equatorial plane. , and where the equatorial plane of the inner sphere extends parallel to the circle plane of the support points of the holder. The restriction of the outer ball shell helps ensure that it does not have to deform too much to be installed above the inner ball shell. However, the ball scales must have a certain extent to ensure a stable grip between them even when their equatorial planes or center axes are angled relative to each other.
    Although bullet parts have only been mentioned here, it should be noted, as stated in claim 6, that the geometry of the surfaces deviates quite a bit from the ideal ball shell. This deviation is intended to ensure that when the inner ball shell's inner ball shell surface is squeezed around the outer ball shell's outer ball shell surface, abutments occur along surfaces that are only small.
    DK 2016 70355 A1 part of the total possible surface area, thereby ensuring that the surface pressure can be multiplied. Thereby, there is a strong grip between the surfaces of the two ball shells, so that a large torque can be transferred from the holder part to the standard part.
    It is preferred that there are at least two threaded holes and associated clamping screws in the clamping ring, the outer ball screw being mounted in the tube such that a first clamp screw pressurizes the ball skull in an area diametrically opposite the gap and a second clamp screw presses the ball skull at an angle displaced 45 degrees in the circumferential direction from the first clamping screw. In this way, it is ensured that the pressure setting of the ball shell is distributed evenly around the outer ball shell surface of the inner ball shell, so that no excessive pressure marks appear on the surface thereof.
    It is also preferred that the outer ball shell in an outer cylinder surface facing the tube has a blind hole for receiving the clamping screw diametrically opposite the gap. This ensures that the clamping screw can hold the outer ball shell rotationally inside the tube.
    The invention will now be explained in more detail with reference to the drawings, in which:
    FIG. 1 is a side view of the Christmas tree foot in graphical representation,
    FIG. 2 shows the Christmas tree foot in a graphical representation in 3d,
    FIG. 3 shows an exploded side view of the Christmas tree foot,
    FIG. 4 shows a section of the clamping ring 11 in a partial sectional drawing,
    FIG. 5 shows a 3d representation of the ball joint and
    FIG. 6 is an enlarged section of a sectional drawing through the ball joint and clamping ring 11.
    DK 2016 70355 A1
    In FIG. 1 and FIG. 2, a Christmas tree foot 1 is shown, which has a holder part 2 arranged for attaching the lower end of the stem to a Christmas tree. A standard part 3 is also shown where a ball joint between the holder part 2 and the standard part 3 is arranged so that it can be locked in a fixed angular position between the holder part and the standard part. A Christmas tree with a not quite straight trunk will then be able to stand in a position so that at least the top of the tree has an approximately vertical center axis.
    In the holder part 2 there is mounted an outer ball shell 5 having an inner ball shell surface 6, and to the standard part an inner ball shell 7 with an outer ball shell surface 8 is mounted. The two ball shell parts 5, 7 can be mounted externally on each other and thereby rotate relative to each other in any direction. The outer ball shell 5 has a cut-through and a corresponding gap 9 extending from an outer surface 10 and through the inner ball shell surface. The slot 9 allows deformation of the outer ball shell both to allow space for the inner ball shell to be inserted in place here and so that the outer ball shell can be clamped around the inner ball shell.
    The retaining member 2 includes a clamp 11 extending around the outer ball shell and in the clamping ring 11 lock screws 13 are mounted in radially extending thread holes 12. When the lock screws 13 are tightened, the outer ball shell 5 is pressed inwardly against the outer ball shell surface of the inner ball shell 7. 9 at the same time decreases. Hereby, the outer ball shell 5 is locked against the inner ball shell 7. As seen in FIG. 3, the locking screws 13 are designed as pin screws.
    The retainer portion 2 comprises a tube 14 which, at a first end 15, is formed as a clamp 11 and has internally mounted the outer ball head 5. At the other end 16 of the tube is mounted the retaining screws 17 which are adapted to fit in radial thread holes 30 and when they screw in, they get squeezed
    DK 2016 70355 A1 towards the stem of the Christmas tree (not shown) which is initially inserted into the tube. The tube has uniform inner and outer circumference, and also has a thickness. It is seen in the enlarged section the sectional drawing of FIG. 6, the outer ball shell 5 is inserted and axially retained at the first end 15 of the tube.
    As shown in FIG. 4 and of FIG. 6, the outer ball shell 5 is axially retained in the tube by locking rings 19 mounted in rotary groove 18.
    The standard part is seen in FIG. 1,2 and 3 and it has a foot 20 with a underside 21. The underside is planar as shown in the figure, and thus has one or more support points in the same plane, and thus at least three support points will be evenly distributed along a circle. The planar underside 21 of the embodiment of choice is appropriate in the material selected, but if the foot, for example, was molded in plastic, a foot with legs starting from a common center would be more appropriate. In a embodiment not shown, in which the foot comprises separate legs, for stability reasons there must be at least 3 legs, and for the best stability, the support points of the legs towards the support should be evenly distributed along a circle. The legs are then assembled at a central area in the center of the circle, and here the legs are joined and the support will be placed.
    In the embodiment shown in the figures, the supporting points, via connecting members 25, are in connection with a central area 24 at the center of the circle 23, with at the central area a mount 26. The mount 26 is mounted directly on the foot 20 with a bolt 30, which also passes through a central hole in the inner ball shell 7. The bolt 30 thus clings the inner ball shell 7 to the mount 26. The inner ball shell 7 is thus mounted on the mount 26 so that the inner ball shell surface 6 of the holder part encloses the inner ball shell 7. outer ball shell 5 can now be angled and clamped to the inner ball shell 7 without
    DK 2016 70355 A1 a lower edge 27 of the holder tube 14 collides with the floor or connecting parts 25 between the supporting points and the central area. By choosing the length of the mount 26 it is then possible to determine how large an angle rotation can be realized.
    The inner and outer spherical shells each extend away from an equatorial plane (not shown) in both directions and are limited by bounding planes parallel to the equatorial plane (not shown) so that they both form sections of a sphere made symmetrically about a large circle which will thus lie in the equatorial plane. The boundary planes may be planar, stepped, convex or concave, or otherwise deviate from a simple planar surface. In FIG. 6, it is seen that the upper boundary plane has been stepped down.
    The outer ball shell 5 of the tube 14 is mounted with its equatorial plane extending perpendicular to the center axis of the tube and the equatorial plane of the inner ball shell 7 extending parallel to the circle plane of the support points of the standard member 3.
    As shown in FIG. 6, the outer ball shell surface 8 of the inner ball shell 7 and / or the inner ball shell surface 6 of the outer ball shell 5 are processed so that one or the other or both differ from the mathematical ball shell shape. In FIG. 6, it is shown how the distance between the two spherical shells 6,8 is greatest at the equatorial plane here stated to be 0.3mm and decreases towards the boundary planes and reaches the minimum of 0.15mm when the two spherical shells are mounted with coinciding center axes. This means that when the outer ball shell 5 is tensioned inwardly against the ball shell surface 8 of the inner ball shell 7, it will be in the areas with the least distance between the ball shell surfaces that contact will occur. As the tension increases, the contact pressure here can become tremendously large, and thus the outer ball shell can actually squeeze a groove into the inner ball shell, and thus
    DK 2016 70355 A1 ensures that the ball joint can transfer quite large moments from the holder part to the standard part.
    In FIG. 1 shows two clamping jaws 13, each of which is threaded into the clamping ring 11 and as seen in FIG. 5, there is a blind hole 28 opposite the one threaded hole 28 in the outer ball shell 5, so that at least one of the screws 13 presses the ball shell through the blind hole 28. As can also be seen in FIG. 5, the blind hole sits directly opposite the slot 9, and thus the outer ball shell is mounted in the tube such that this clamp screw presses the ball shell 5 in an area diametrically opposite the slot 9. The second screw screw presses the ball shell at an angle offset 45 degrees in the circumferential direction from the first clamping screw 13 as shown in FIG. First
    As seen in FIG. 5, there is a further location mark 32 which may help to ensure that a pre-assembled ball joint consisting of the inner ball shell 7 and the outer ball shell 5 can be properly inserted into the end portion 15 of the pipe 14 so that the blind hole 28 is exposed. one of the threaded holes 12.
