Abstract

An automatic artificial Christmas tree using an improved one-piece plastic molded branch holding ring and spacer combination for use with twisted wire stem branches or other suitable metal wire branches without the need to resort to individual branch attaching connectors. According to the disclosed method of assembly, the branches used have a straight wire stem. The stem of each branch is first inserted into a branch receiving radial slot of a branch holder. Its free end is then raised upwardly from the horizontal position to the vertical or beyond to form a hook for pivotally connecting the branch to the holder.

Claims

1. An automatic artificial tree comprising at least one main section, said main section comprising vertically extending support means, a plurality of branch holders of hollow construction mounted to said support means, coaxially thereof, a plurality of branches pivoted to said branch holders for projecting radially and generally perpendicularly of said support means when said main section is in its normal upright position but free to fold to a collapsed position generally parallel to said support means when said main section is upside-down, each branch holder comprising a branch holding ring and a tubular spacer, depending from said ring in fixed relationship thereto, each branch holding ring comprising a generally planar disc-shaped body of rigid material, with a central hole for including said support means, a coaxial fulcrum ring on the upper surface of said disc-shaped body, a plurality of radially extending branch receiving slots on said upper surface below said fulcrum ring, said slots having laterally confining means, each branch having the tip of its inner end bent upwardly behind said fulcrum ring at such an angle that upon movement of the tree to an upright position, the bent inner end is free to swing down about the fulcrum ring until the branch rests in its respective slot.

2. An automatic artificial tree as defined in claim 1, including a top section separate from the said main section and means for attaching the top section to the top of the main section or sections.

3. An automatic artificial tree as defined in claim 1, said support means comprising an elongate vertically extending support pole, the said branch holders being coaxially mounted on said support pole, the uppermost and lowermost branch holder being secured to the support pole.

4. An automatic artificial tree as defined in claim 1, and including further laterally confining means aligned with each slot and located on the opposite side of the fulcrum from said slot, said further laterally confining means having a pair of opposed vertically extending surfaces for guiding the bent part of a branch.

5. An automatic artificial tree as defined in any one of claims 1, 3 or 4, wherein said radially extending branch receiving slots are relatively deep and extend in straight line from the outer edge of said disc-shaped body, parallel to the plane thereof, radially inwardly, thereby to completely receive the portion of the stem of the associated branch which is adjacent to the tip thereof, said slot being sufficiently long as to prevent excessive lateral movement of said branch when supported in said slot.

6. An automatic artificial tree as defined in claim 5 wherein each branch holder comprises a number of said branch receiving slots comprised between six and twelve.

7. An automatic artificial tree as defined in claim 6 wherein said branch holding ring and said spacer in each of said branch holders are integrally formed, each branch holder being a one-piece plastic molded component with an integrally formed fulcrum ring.

8. An automatic artificial tree as defined in claim 7 wherein in branch holder comprises a coaxial nesting socket on the upper surface of its branch holding ring, said nesting socket receiving the lower end of the spacer of the branch holder disposed immediately above it and conforming generally to the shape thereof, each of said branch receiving slots opening at said nesting socket.

9. An automatic artificial tree as defined in any one of claims 1, 3 or 4 wherein each branch holder comprises indexing means for determining the angular relationship of successive branch holders in nesting relationship on said support means, said indexing means comprising a projecting tab at one end of each branch holder, and two angularly spaced apart tab receiving sockets, the position of one tab receiving socket relative to the other being such as to offer a choice between vertical alignment of the branch receiving slots of successive branch holders, on the one hand, and vertical alignment of the branch receiving slots of alternate branch holders, on the other.

10. In an automatic artificial tree, a plurality of vertically nested branch holders mounted to a common support pole, each branch holder being a one-piece plastic molded component and having a tubular spacer and a branch receiving ring at the upper end of said spacer, said branch receiving holder consisting of a relatively thick disc-shaped portion having a central aperture in communication with the central hole of its spacer, a coaxial nesting socket for receiving the lower end of the spacer of a branch holder, if any, directly thereabove, about twelve radially extending branch receiving slots into said disc-shaped body, extending to a common plane which contains the bottom surface of said nesting socket, an integral fulcrum ring bridging said branch receiving slots a sufficient distance outwardly of said support pole, each branch holder also having laterally confining means between said fulcrum ring and said nesting socket, said laterally confining means presenting two vertically extending surfaces at the inner end of every branch receiving slot, said automatic artificial tree also comprising a plurality of branches pivotally connected to said branch holders, each branch having a metal wire stem whose inner tip is bent upwardly behind said fulcrum ring between said laterally confining means to form and acute angle with the adjacent portion of said stem.
