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.
