[0001] The present invention relates to an artificial Christmas tree, in particular to a
collapsible tree which is assembled from a kit of parts including identical stem sections
which may be fitted together to form trees of different heights, the stem sections
including means for inserting branches therein.
[0002] Numerous constructions for an artificial Christmas tree have been described in the
prior art, wherein the stem is not collapsible and comprises a stiff rod or pole,
to which the branches either must permanently be attached, or slotted into a series
of collars, or holes drilled in the pole, with the option that the branches may be
folded back or removed for storage. The branches tend to break off very easily, and
a long box is required to ship the product.
[0003] The prior art also includes constructions for an artificial Christmas tree having
a collapsible stem section. According to our Irish Patents Nos. S59161 and 68051,
the collapsible stem comprises a series of identical hollow tubes which are rigidly
interengageable, each having a male section at one end and a female section at the
other, such that when the two are coupled together a series of longitudinal slots
is defined at the junction between them. The roots of the branches are inserted in
the slots, with both a male and a female section bearing against the branches to wedge
them tightly in place. However, on account of the diameter of the tubes, only about
six slots can be accommodated. In a taller tree, this does not allow for a very dense
array of branches near the base, which is a disadvantage. Also, for disassembly purposes,
it has been found that the customer may prefer to strip off the branches leaving the
assembled tubes comprising the stem intact, but in the arrangement disclosed in IE-S59161
and IE-68051, the branches can only be removed by completely disassembling the tubes
comprising the stem, which is time-consuming.
[0004] 0ther arrangements including interengageable tubular stem sections are disclosed
in GB-A-0,303,270 and GB-A-0,874,704. An arrangement with alternate tube sections
and collar sections is described in EP-A-0,527,711. However, all of the artificial
Christmas trees described in this prior art require to be completely disassembled,
i.e. all of the stem sections must be separated, to satisfactorily remove the branches,
for storing the tree. This of course weakens the parts.
[0005] It is therefore an object of the present invention to combine the advantages of a
fully collapsible artificial Christmas tree construction, i.e. ease of shipment in
a smaller box, flexibility in terms of assembling trees of different heights, reduced
manufacturing costs, etc., with the advantages of the partially collapsible type of
construction, i.e. where only the branches need to be removed for the purpose of storing
them in a box, and saving the tree from deteriorating from one Christmas to the next,
say in an attic or garage.
[0006] The present invention aims to provide a very strong stem assembly, where the sections
may even be pre-assembled prior to shipment or assembled by the customer. Furthermore,
while providing a series of protruding collars or sleeves for slotting the branches
onto the stem may give the stem a somewhat unnatural appearance, the present invention
seeks to overcome this problem by providing a collar with over ten slots, preferably
fifteen, about its circumference, such that branches may be quite densely packed,
when attached, thereby giving an artificial Christmas tree where the stem (and the
collars) are not easily visible between the mass of branches when the tree is finally
assembled.
[0007] Accordingly, the present invention provides an artificial Christmas tree assembled
from a kit of parts including stem sections which may be fitted together by means
of male and female portions to form trees of different heights, branches comprising
a root portion and a leafy portion, and collars defining a series of logitudinal slots,
for receiving the root portions of the branches, and each collar defining on its outer
periphery a parapet with a gap adjacent to each slot for receiving the base of the
leafy portion of each respective branch, adapted to maintain the branches in firm
engagement with and radially spaced with respect to the stem
characterized in that the collar is integrally formed with the stem section and the slots defined therein
are coincident with the outer sidewall of the stem, such that the branches may be
inserted and removed after the stem sections have been assembled, in use.
[0008] The collar is preferably spaced from one end of the stem section. Each stem section
is most preferably identical, comprising a male portion at one end and a corresponding
female portion at the other end. The stem sections are preferably hollow, but they
may be solid.
[0009] The male and female portions preferably may be coupled together with a tight or interference
fit for maximum rigidity.
[0010] Suitably, there are at least ten, and preferably fifteen, slots defined in the collar.
[0011] A preferred embodiment of the invention will now be described with reference to the
accompanying drawings, in which:
Figure 1 is a longitudinal cross section of a stem section for an artificial Christmas
tree;
Figure 2 is a plan view from above of the stem section shown in Figure 1,
Figure 3 is a plan view from below of the stem section shown in Figure 1,
Figure 4 is the same view as in Figure 3, showing part of three tripod legs attached,
and,
Figure 5 is a side view of a preferred tripod leg for the base of the artificial Christmas
tree.
[0012] An artificial Christmas tree in accordance with a preferred embodiment of the present
invention is assembled from identical tubular stem sections (1) as shown in Figure
1. The top male portion (2) is slightly tapered so as to fit inside the bottom female
portion (3) with a tight or interference fit. However, in an obvious equivalent, two
stem sections could be used, one defining a male portion at each end, the other defining
a female portion at each end, fitting together alternately. A collar (4) is integrally
formed in a mould on the outside of the stem section and comprises a ledge (5) which
defines fifteen longidutinal slots (6) about its circumference. Each slot receives
the root portion (7) of a branch for the tree, which will not be described in detail
as the branches are of a known construction. A leafy portion (8) of the branch projects
out from the collar (4) and is accommodated by a notch (9) formed in a parapet (10)
formed on the collar.
[0013] This arrangement provides a firm seating for the branches which may be inserted in
some or all of the slots, as desired, once the stem sections have been joined together.
It should be noted that the end surface (11) of the female portion engages with the
ledge (5) when the sections are pressed tightly together, but does not interfere with
the insertion or removal of the root portions (7) of the branches, since the slots
(6) for receiving the branches are coincident with the outer sidewall of the stem
sections (1). Therefore, once the stem sections have been assembled, the branches
can be inserted and removed quickly. In most cases, the customer is content to leave
the stem sections joined together for storing the parts until the next Christmas.
0nly the branches and tree decorations need to be stored in a box.
[0014] 0n the underside of the collar (4) a skirt portion (12) is formed, with three large
notches (13) formed therein, for receiving three tripod legs (14). A pin (15) is formed
on each tripod leg, positioned to slot into the slots numbered 6a in Figure 3. A hook
(16) is positioned to fit into the female portion (3) engaging with the edge (11)
of the stem section. As seen in Figure 4 each of the three tripod legs (14) abut each
other when inserted in the bottom stem section of the artificial Christmas tree assembly,
so that the legs are sturdy and cannot move laterally.
