8 Claims, 7 Drawing Figures ASYMMETRIC ARTIFICIAL CHRISTMAS TREE This invention relates to an asymmetrical artificial tree assembly especially of the type which may be adapted to receive decorations such as electrical light bulbs for use as a Christmas tree. The tree is uniquely designed in order that it may be assembled to form a full tree, a half tree, or a quarter tree, depending on the particular location where the tree is to be displayed. For example, it is intended that the half tree assembly be used when the tree is set up for display against a wall or that the quarter tree assembly be used when the tree is set up for display in the corner of a room. A number of other advantages of the artificial tree assembly of the instant invention are: the tree is easily and quickly assembled in either of the three configurations which will most likely facilitate the economical use of available display space, the tree maintains the decorative and aesthetic qualities which a Christmas tree is intended to possess, and the construction is both inexpensive and safe.

It is, therefore, an object and feature of the instant invention to provide an artificial tree assembly comprising a base member which supports a plurality of angular elements to define at least a portion of a cone; the

angular elements including arm members extending radially from the base member and upright strut members extending upwardly and inwardly from the outer ends of the arm members to the apex of the cone.

It is another object and feature of the instant invention to provide an artificial tree assembly having a plurality of selectively interchangeable configurations.

In correlation with the foregoing objects and features it is another object and feature of the instant invention to provide an artificial tree assembly which includes a plurality of electrical light bulbs attached thereto and electrical conducting means disposed within the angular elements for conducting electrical power to the light bulbs.

Other objects and attendant advantages of the instant invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

FIG. 1 is a front elevational view of a preferred embodiment of the instant invention;

FIG. 2 is an exploded side elevational view of a preferred embodiment of the instant invention;

FIG. 3 is a fragmentary view, partially cut away, of the base member;

FIG. 4 is a fragmentary exploded view of the connection between the arm members and strut members;

FIG. 5 is a side elevational view of a quarter tree constructed in accordance with the instant invention;

FIG. 6 is a plan view of a base member; and

FIG. 7 is a fragmentary view of an alternate embodiment of the instant invention.

Referring to the drawings, an artificial tree assembly is generally shown at 10. The tree assembly 10 includes a plurality of angular elements 12 supported on and attached to a base member 14 to define at least a portion of a cone. The angular elements 12 include arm members 16 which extend radially from the base member 14 and upright strut members 18 which extend upwardly and inwardly from the outer end 20 of the arm members 16 to the apex of the cone generally shown at 22. The tree assembly includes crown or cap member 24 which holds and joins the strut members 18 together at the apex of the cone.

The base member 14 includes an upper supporting surface 26 having a plurality of radially extending grooves 28 disposed thereon for nesting the arm members 16. The upper surface 26 of the base member is concave to define a dish-like surface as best shown in FIG 3 and the arm members 16 are provided with a bend 30 thereby causing the arm member 16 to extend slightly upwardly as well as radially to enhance the decorative effect of the resulting tree assembly.

The base member 14 includes fastener means consisting of a removable cap member 32 having a plurality of downwardly opening arcuate slots 34 disposed in a depending flange thereof. The cap member 32 includes hole 36 through which a threaded stud 38 which is mounted in the base member extends for receiving a wing nut 40 thereon to clamp the cap member 32 over the arm members 16 thereby holding the arm members 16 within the grooves 28 on the supporting surface 26 of the base member 14.

The tree assembly 10 may be provided with a plurality of electrical light bulbs 42 which are threaded into the arm members 16 and upright strut members 18. The light bulbs 42 disposed on the strut members 18 may be arranged in spiral fashion to increase the number of light bulbs thereby enhancing the beauty of the tree.

Obviously a number of suitable methods for supplying electrical current to the electrical light bulbs 42 would be obvious to a man skilled in the art. One electrical setup, which functions quite satisfactorily, includes disposing a low voltage transformer 44 within the base member 14. The transformer 44 is connected to any standard wall socket through a standard electrical cord 46. The transformer 44 is connected to a multiple outlet box 48 disposed on the base member 14 by anysuitable electrical connection such as line 50. Transformer 44 not only reduces the line voltage from a wall socket to a level which will meet safety regulations for electrical devices of this nature such as under 52 volts, but also adds weight to the base to stabilize the tree assembly 10 to prevent the tree assembly 10 from tipping over if accidentally jarred.

The outlet box 48 includes a plurality of outlets for receiving prongs 52 which protrude from the arm members l6 and are connected to electrical currentcarrying wires 54 encased within the arm members 16. Each arm member 16 includes an upwardly extending elbow portion at the outer end 20 thereof having a central bore 56 for receiving and holding the lower end 58 of the upright strut member 18. Disposed'in the base of the bore 56 is a socket 60 for receiving a prong 62 extending from and connected to an electrical currentcarrying wire 64 encased within the strut member 18. The electric current-carrying

lines

54 and 64 in the arm members 16 and strut members 18 supply current to the sockets which hold the electrical light bulbs 42.

The tree assembly 10 as shown in the drawings includes six angular elements 12 which may be divided into adjacent pairs wherein the strut members 18 of each pair are electrically connected at the apex of the tree assembly 10 whereby each pair of angular elements comprises one electrical circuit or loop.

The bore 56 includes an additional socket 66 for receiving a prong 68 which extends from the strut member 18 and is provided to insure the proper angular positioning of the strut member 18 in respect to its mating arm member 16 and also to prevent the strut member 18 from rotating within the bore 56 while the tree is on display.

The tree assembly 10 shown in FIGS. 1 and 2 illustrates the half tree construction. The half tree is formed by using two substantially shorter arm members 16 at the rear of the base member; that is, two adjacent arm members 16 at the rear extend only slightly beyond the edge of the supporting surface 26 of the base member 14.

A full tree construction is not shown. However, it is to be understood that to construct a full tree would merely require the replacement of the two short arm members 16 with two full length arm members. Note that the strut members 18 are of a standard length and need not be of different lengths since the difference in height at the apex of the tree resulting from the use of the shorter arm members is hidden by the cap member 24.

The base member which is used in the full tree or half tree assemblies is provided with six radially extending grooves 28 as shown in FIG. 2. An artificial tree 10 which may be constructed in the form of a quarter tree requires four additional grooves 28 in the supporting surface 26 of the base member 14, as shown in FIGS. 5 and 6. To construct a quarter tree, five full length arm members 16 with their strut members 18 are disposed within grooves 28 which are grouped within a 90 quadrant of the supporting surface 26, and one short arm member 16 and its upright strut member 18 is disposed at the rear. The rear arm member 16 and strut member 18 provide support for the forward strut members to stabilize the assembly.

The base member 14 includes indicia consisting of numbers 1 through generally shown at 69 of FIG. 6 for identifying the grooves 28 and for specifying the combination of grooves 28 selected to hold the angular elements 12 to form one of the particular tree configurations. For example, and referring specifically to FIG. 6, the assembly directions for constructing a full tree would direct the use of six full length arm members 16 which are to be disposed within

grooves

3, 6, 7, 8, 9 and 10. An assembly direction for a half tree would the use of four full length arm members 16 in

grooves

3, 6, 7 and 10 and two half length arm members 16 in grooves 8 and 9. Accordingly, for a quarter tree the assembly directions would direct the use of five full length arm members 16 in

grooves

1, 2, 3, 4 and 5 and one short arm member 16 in groove 8. It is to be understood that the strut members 18 are connected to the arm members 16 in the same manner, regardless of whether the strut member is inserted in a standard length or short arm member 16.

The tree assembly 10 may support specially adapted panel members one of which is shown at 70 which are connected to the angular elements 12. The panel members 70 are constructed of a light weight plastic material in the form of a mesh so that they might receive and support ornaments 72 or other decorative objects. The

- panel member 70 may extend between adjacent upright strut members 18 of the angular elements 12 as shown in FIG. 5 or may extend radially from the center of the base member in which case they are adapted to be connected to the arm member 16 and upright strut member 18 of each of the angular elements 12, as shown in FIG. 7. The panel member 70 is designed to give the tree assembly 10 more body and a fuller appearance. The panel members are provided with clips 76 which snap around the arm member 16 or strut member 18 to hold the panel members 70 in position.

The invention has been described in illustrative manner and is to be understood that the terminology that has been used is intended to be in the nature of words of description rather than of limitations.

Obviously, many modifications and variations of the instant invention are possible in light of the above teachings. It is, therefore, to be understood that the invention may be practiced otherwise than as specifically described herein.
