Abstract

An artificial Christmas tree may be assembled from a kit of parts including stem sections (1) which are fitted together by means of male (2) and female (3) portions to form trees of different heights. Branches are provided comprising a root portion (7) and a leafy portion (8), wherein the stem sections each include a collar (4) formed integrally with the stem section and defining a series of longitudinal slots (6), for receiving the root portions of the branches. A parapet (10) on the collar defines a gap (9) 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. The slots (6) are coincident with the outer sidewall of the stem, such that the branches may easily be inserted and removed after the stem sections have been assembled, in use. A novel tripod leg (14) arrangement is also disclosed. <IMAGE>

Description

AN ARTIFICIAL CHRISTMAS TREE 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.

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 must be either permanently 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.

The prior art also includes constructions for an artificial Christmas tree having a collapsible stem section. According to my 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. The roots of the branches are inserted in the slots, but 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 - 2 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.

Other arrangements including interengageable tubular stem sections are disclosed in GB-A-O,3O3,27O 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.

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.

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 using a collar or sleeve 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 type of 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 when finally assembled.

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, wherein the stem sections each include a collar fixed - 3 to the stem section and defining a series of logitudinal slots, for receiving the root portions of the branches, and 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 the stem characterized i 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.

The stem sections are preferably hollow, but they may be solid.

The male and female portions preferably may be coupled together with a tight or interference fit for maximum rigidity.

Suitably, there are at least ten, and preferably fifteen, slots defined in the collar.

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, s Figure 5 is a side view of a preferred tripod leg the artificial Christmas tree. for the base of An artificial Christmas tree in accordance with a preferred embodiment of the present invention is assembled from identical tubular - 4 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.

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. Only the branches and tree decorations need to be stored in a box.

On 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.
