Filed Feb. 18, 1969, Ser. No. 800,218 Int. Cl. A47g 33/08 US. Cl. 161-14 11 Claims ABSTRACT OF THE DISCLOSURE Artificial trees, particularly those used for Christmas decoration have become increasingly popular generally because of reduced fire hazards through the use of noncombustible materials, durability, ready storage and continued reuse over a number of years.

Primary objects of the present invention are to provide an artificial tree which can be readily collapsed and stored and in which the simulated foldable limbs of the tree substantially unfold with a minimum of effort and without physically distorting tree-forming elements;

To provide a novel artificial tree which includes foldable limbs mounted on a simulated trunk which affords a natural appearance;

To provide a novel means for pivotally mounting artificial tree limbs on a hollow tree trunk; and

To provide a novel artificial tree which is automatically folded when inserted into a tubular storage container and is automatically unfolded when removed from the container.

Referring to FIGS. 1 and 2, a fragmentary portion of an artificial tree, generally of the type used for Christmas decoration is indicated generally at 10 and comprises a vertical or central support staff or trunk 12 and a plurality of longitudinally and circumferentially spaced artificial limbs or branches indicated generally at 14. The lower end of the trunk 12 will be maintained vertical in a suitable base or support stand, not shown. Additionally, both the trunk and branches 12 and 14 will be produced from any suitable material preferably non-inflammable. Additionally, the trunk 12 may taper from its lower toward its upper end to more closely simulate an artificial tree. The limbs or branches .14 are pivotally connected at their inner ends to the trunk 12 in a manner to subsequently be described in detail, and will normally gravitate to the condition shown in FIG. 1 from that indicated at 10' in FIG. 2. The branches or limbs 14 are readily folded to the condition shown in FIG. 2 by inserting the artificial tree in a suitably dimensioned elongated rectangular carton or cylindrical tube.

Referring to FIGS. 3 and 4, the limbs 14 comprise a pair of longitudinally twisted, fairly stiff wire elements 16 and .13 which form a plurality of longitudinally spaced loops 20 through which are transversely disposed foliageforming filaments 22 of plastic which afford simulated pine needles or the like. The branches or limbs 14 will be graduated in length to provide various elevational profiles to the artificial tree. The wires 16 and 18 terminate at their inner ends in oppositely directed trunnion portions 24 and 26, respectively, which define the support shaft for the branches 14.

Referring to FIGS. 5-8, the simulated trunk 12 may be constructed of any suitable material, metal, plastic, etc., and comprises an elongated tubular member 28 having suitably formed therein in longitudinally and circumferentially spaced relation a series of cooperating slots and pivot apertures. Each of the series of slots and pivot apertures comprises an elongated slot portion 30 flanked on opposite sides by relatively shorter, diametrically opposed pair of apertures 32.

With respect to a given series of slots and apertures, it will be noted that slot 30; see FIG. 7, has a lower shoulder or terminal abutment portion 34 which is in substantial horizontal alignment with the upper end 36 of its respective pair of cooperating and diametrically opposed apertures 32.

The slot 30 will have an overall length substantially equal to or greater than the overall combined length of the trunnion portions 24 and 26, and these portions as indicated at 24' and 26' in FIG. 6, may be readily introduced through a slot 30, threafter being rotated about the longitudinal axis defined by the wires 16 and 18', and the trunnion portions 24 and 26 will be pivotally received within the pair of pivot apertures 32 which flank the respective longitudinal slots 30. It will be noted that when the branches or limbs 14 are assembled in the manner illustrated in FIGS. 6 and 7, by virtue of the substantially horizontally aligned abutment portions 34 and 36 of the respective slots and apertures, the branches will be oriented substantially horizontally and be prevented by the abutment portion 34 from pivoting extensively in a downward direction. The branches 141 may be slightly curved upwardly to simulate a normal growing appearance of a typical natural Christmas tree.

As illustrated in FIGS. 7 and 8, the slots 30 and 30' may be disposed in diametrically opposed relation, wherein a single pair of flanking pivot apertures 32 accommodate the trunnion portions of two limbs 14.

As illustrated by phantom lines in FIGS. 1 and 2, a tubular container C having a rectangular, polygonal, or circular cross section will removably receive the artificial tree when folded in the condition shown in FIG. 2. When the artificial tree as shown in FIG. 1 is inserted into the container or tube C, the limbs 14 automatically fold upwardly toward the position shown in FIG. 2, and when the tree is entirely contained within the tube, the tree is folded and stored.

Of course, when the tree is removed, upper end first, from the container, as the limbs are being withdrawn from the embrace of the tube, the uppermost limbs will automatically gravitate radially outwardly to an unfolded condition, i.e. as shown in FIG. 1.

Referring to FIGS. 9 and 10, a fragmentary portion of the Christmas tree is indicated generally at 1:10, comprising a central vertical trunk or staff 112. and a plurality of longitudinally and circumferentially spaced limbs or branches 114-. Wherever possible, reference numerals of the 100 series will be utilized to identify structure illustrated in the embodiment of FIGS. 9-16 to accordingly identify structure and function which is comparable to that of the embodiment of FIGS. 1-8.

The trunk 1112 can taper vertically upwardly, and the branches or limbs are supported in radially extending. relation when unfolded to automatically assume the condition shown in FIG. 1. The limbs or branches 114- remain pivotally connected to the trunk 112 when the tree is stored or taken down; however, if the branches are damaged, they can be readily replaced.

In both disclosed embodiments, as mentioned above, the storage container C will facilitate automatic folding into stored relationship as well as automatic erection when the tree is removed from the container and the branches gravitationally descend to the radially disclosed position.

In FIGS. 13 and 14 the trunk 112 is illustrated as being tubular or hollow; however, a solid rod may like wise be used.

The trunk 112 has distributed in vertically spaced relation, and in oifset relationship generally to the longitudinal axis or center line of the trunk, pairs of diametrical- 1y opposed bearing apertures 116, 118, etc. which comprise trunnion-bearings, which define a pivotal axis PA between each respective pair of apertures. The pivot axes PA are generally in chordal relationship to the center line of the trunk or staff 112. For purposes of clarity, only a single pair of apertures 116 is shown in FIG. 14, for example.

The tree branches 11 1 comprise twisted wire elements 120 forming loops in which are secured plastic filaments 122 simulating pine needles, for example. The twisted wire elements from a shank portion 124 which will have soldered, welded or otherwise secured thereto an adapter indicated generally at 126; see FIG. 11. The adapter 126 comprises a pair of generally parallel legs 128, 130 integrally connected at one end by a bight portion 132, and having intermediate outwardly extending generally arcuate arms 134, 136, concluding in reverse-bend coaxial trunnion or stub shafts 133, 141), respectively. The arms are spring-like and can be displaced or sprung outwardly to a sufiicient degree to accommodate the trunnion shaft 138, 140 in the aligned pair of apertures 116; see FIG. 14. The legs 12%, 130, as previously mentioned, are welded, soldered or otherwise secured to the shank portion 124 1 of the artificial limb or branch 114. However, the wires 12%), if desired, can have integrally formed therewith the legs 128, as well as the arms 134, 136 and their trunnion shafts 138, 140, thus eliminating the necessity for welding, soldering, etc.

The legs 128, 1311 are provided with an intermediate angular-bend forming an obtuse angle of approximately whereby when the limbs 114 are pivoted upwardly on their trunnion shafts substantially 90 to phantom line position shown, the limbs will be in substantial overlying parallel relationship to the center line or longitudinal axis of the trunk 112. As mentioned before, the arms are sufficiently displaceable to permit the trunnion shafts to be separated (see phantom lines in FIG. 16) to permit removal and replacement or installation of the branches 114.

Briefly, in review, the artificial limbs or branches 14 or 11 by virtue of the trunnion portions are readily pivotally mounted in pivot apertures or bearing portions as seen in FIG. 6 or FIG. 15, respectively, and are freely pivoted in an upward direction for collapsing the tree as seen in FIGS. 2 and 10 and will automatically gravitate due to their cantilevered pivotal connection to an unfolded" condition shown in FIGS. 1 and 9. The slots and cooperating pivot apertures in the artificial tree trunks 12 or 112 eliminate the necessity for additional hardware, etc., and alford an economy of assembly and construction which was heretofore never realized. Further, the trees can be deposited in a storage carton or tube automatically collapsing the tree limbs, and when the tree is pulled from the container C it automatically opens or unfolds.

However, as is clearly evident, removal of the tree from the tube results in automatic erection or radial gravitation of the branches. In addition, the slots and cooperating pivot apertures in the artificial tree trunks 12 or 112 eliminate the necessity for complex hardware, particularly in the case of the embodiment of FIGS. 916, wherein the tree trunk or staff can be either hollow or solid.

It will be obvious to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown in the drawings and described in the specification.
