comprising a bottom part


3


, and a tree-accommodating supporting part


4


;


304


, which is supported by the bottom part


3


;


303


, has means of adjustment


5


between the aforementioned parts


3


,


4


to permit the adjustment of the aforementioned tree-accommodating supporting part


4


to a desired angle X of approximately


5


° in each direction


6


,


7


along the periphery of the aforementioned bottom part


3


, and exhibits a spring


8


to hold the parts together at the desired angle X.




The central part


9


of the bottom part


3


exhibits a curved outer convex contact surface


10


for a spring


8


capable of bearing against it. A connection


11


extends through the central part


9


between the spring


8


and a holder


13


capable of being accommodated in the internal accommodating part of the aforementioned central part, which holder is attached to the supporting part


4


.




The downward-facing, spherical, curved bottom part


4


A of the supporting part


4


exhibits a congruent form with a corresponding concave, internally curved accommodating surface


14


in the bottom part


3


of the central part


9


.




The central part


9


of the bottom part


3


exhibits a central opening


15


, in which a stopping part


17


projecting from the superjacent supporting part


4


in a downward direction


16


is accommodated in a movable fashion such that it is capable of adjustment to the desired angle X for the supporting part


4


.




The aforementioned stopping part


17


is also connected to the spring


8


, in conjunction with which the connection comprises an adjustable screw


11


accommodated in a retainer


18


in the supporting part


4


.




The spring


8


comprises, in the first illustrative example shown in

FIG. 1

, a sprung disc


8


A with an annular contact edge


8


B with a correspondingly shaped pressure surface


8


C which makes contact with the aforementioned contact surface


10


of the bottom part


3


.




Each of two pins


19


projects from the sprung


8


and into its corresponding opening


20


in the supporting part


4


, where it functions as a spring guide so that the spring


8


and the supporting part


4


do not change position in relation to one another.




According to other embodiments, the spring


108


is in the form of a spherical, curved spring washer consisting of springy metal, the curvature of which in the unloaded position differs from the downward-facing


16


curved external contact surface


110


of the bottom part


3


, i.e. the spring


108


exhibits a curvature of which the radius R


1


is less than the radius R


2


of the aforementioned contact surface


110


. See FIG.


9


.




This embodiment of a Christmas tree stand


102


also exhibits a guide pins


119


for the spring


108


, which is also held securely in a centrally located frame part of the supporting part


104


and forms a projecting stopping part


117


accommodated in a circular central opening


115


in the central part


109


of the bottom part


103


in order to limit any tipping of the supporting part


104


around the vertical central axis


150


of the stand. Holes


57


;


157


in the spring


8


;


108


accommodate the pins


19


,


110


. The accommodating openings


120


for the aforementioned pins


119


in the aforementioned frame part in the supporting part


104


retain the pins


119


and with it the spring


108


in position on the supporting part


104


. A threaded insert


18


;


118


attached to the center of the supporting part


104


and functioning as a holding part provides an attachment for a screw


11


,


111


which is screwed in through a centrally located opening


52


,


152


in the spring


8


;


108


.




The aforementioned insert


18


;


118


which forms a holding part may comprise a piece of iron or some other holding part with matching threads capable of being introduced into a laterally


54


,


154


extending channel


53


,


153


.




Illustrated in

FIGS. 4 and 4A

is a piece of iron


118


of this kind which forms a holding part with a threaded hole


156


for the screw


111


and two openings


120


for the pins


119


.




The stop part thus projects downwards from the frame part in such a way that it is capable of being adjusted in the central opening in the central part to the extent that, at its full inclination, it comes into contact with the peripheral edge of the opening, thereby stopping further angular adjustment of the supporting part


4


;


104


. The aforementioned supporting part is tubular, and the frame part


3


;


103


is disc-shaped with sides


3


A;


103


A inclined at a shallow angle and has a centrally located, upward-projecting collar


60


,


160


, in conjunction with which an annular lower part


58


;


158


in the supporting part


4


,


104


is so arranged as to enclose the aforementioned collar


60


,


160


, thereby preventing water from running down over the collar


60


,


160


into the lower part of the stand.




A similar connecting part is illustrated in

FIG. 5

, in conjunction with which the pins


219


are formed by a common part in the form of a sleeve


275


, in which a screw


211


is accommodated and is screwed into a piece of iron


218


which forms a stopping part provided with a threaded hole


256


,


220


, as described above.




The embodiment of a stand


302


illustrated in

FIGS. 8 and 9

differs from the stands described above and in the other Figures in that the screw


311


connecting the spring


308


to the supporting part


304


at its bottom part is accommodated screwed into a sleeve


381


secured in an opening


380


in the bottom part, which sleeve has internal threads


382


to interact with the screw


311


.




Furthermore, the pins


319


are accommodated in holes


320


in the formed stopping part


317


that is accommodated in an opening


315


in the bottom of the bottom part


303


. The function of the aforementioned arrangement


301


is the same as that described above.




By screwing the screw


11


,


111


,


211


,


311


to a different extent into the supporting part


4


,


104


,


204


,


304


, it is possible to adjust the desired spring force so that the supporting part can be tilted manually to the desired angle X after securing a Christmas tree in it by means of upper securing screws


45


around its periphery, for example if the Christmas tree


46


is inclined.




By adapting the distance so that the spring is caused to make contact with the stopping part


17


, a suitable spring force will have been achieved to enable the Christmas tree to be adjusted conveniently in the desired direction, and to ensure that the Christmas tree also stands securely in the stand.




The sleeve


275


illustrated in

FIG. 5

functions in this case as a distance piece in the manner described above, in that a contact edge


290


of the sleeve


275


comes into contact with the piece of iron


218


acting as a holder and a stopping part.




The invention is not restricted to the illustrative embodiments described above and illustrated in the drawings, but may be varied within the scope of the Patent Claims without departing from the idea of invention.
