Abstract

An artificial christmas tree apparatus includes a plurality of movable branches which are closeable and openable through the relative motion of an inner and outer tube arrangement which forms the trunk mechanism of the tree. Each branch includes a decorated leafy end and an oppositely located base end which is received in the trunk mechanism. The trunk mechanism comprises an outer tube having a first and a second aperture therein and an inner tube located within said outer tube. The inner tube includes a third and fourth aperture therein. The second aperture is larger than the first aperture and the third aperture is larger than the fourth aperture. The base end of each branch passes through said second, fourth, third and first apertures respectively and is anchored by a crimp located at one end of the branch. Relative motion of the inner and outer tubes causes the branches to move from a closed to an open position and vice versa. A stand supports the apparatus and may be employed to drive the trunk mechanism. Alternatively, manipulation of the branches themselves will cause the erection or collapse of the device.

Claims

1. A collapsible artificial tree apparatus comprising:

a plurality of tree branches, each branch having a base end and a decorated free end;

a hollow outer tubular means having a plurality of first and second apertures therein, said second apertures being longer in one dimension than said first apertures;

a hollow inner tubular means located within said hollow outer tubular means, said hollow inner tubular means including a plurality of third and fourth apertures therein, said third apertures being longer in one dimension than said fourth apertures, said first apertures being located next to said third apertures and said second apertures being located next to said fourth apertures; and

,

a stand means connected to said apparatus for supporting said apparatus,

wherein the base end of each of said branches pass continuously through a second, fourth, third and first aperture respectively so that the relative movement of said hollow inner tubular means within said hollow outer tubular means causes movement of said branches from one position to another position.

2. The apparatus of claim 1 wherein said stand means includes a plurality of leg means and wherein the spreading of said leg means causes said hollow inner tubular means and said hollow outer tubular means to move in such a fashion as to cause the branches to assume a full open position.

3. The apparatus of claim 2 wherein said second and third apertures comprise slots in said hollow outer tubular means and said hollow inner tubular means respectively, said slots being oriented parallel to the long axis of said hollow inner and outer tubular means.

4. The apparatus of claim 3 wherein the base end of each of said branches includes an anchor means for preventing said branches from slipping through said first aperture.

5. The apparatus of claim 4 wherein the base end of each of said branches is substantially flattened.
