Controlled diameter collapsible artificial christmas tree
First Claim
1. An artificial tree with changing diameter, said tree comprising:
- an outer trunk shell including a multitude of elongated openings along and around said outer trunk shell;
a threaded inner core within and coaxial to said outer trunk shell;
a multitude of threaded branch translators threaded onto said threaded inner core and aligned with said elongated openings in said outer trunk shell;
a multitude of branches passing through said elongated openings in said outer trunk shell and pivotally attached to said threaded branch translators such that said branches are free to rotate in planes parallel to the central axis of said outer trunk shell; and
means for rotating said threaded inner core such that the rotational motion of said threaded inner core is transformed into linear motion of said threaded branch translators along the length of said threaded inner core causing said branches to rotate along the length of said outer trunk shell and changing the diameter of said tree.

Abstract
The invention relates to an artificial tree that can be reduced in diameter by rotating its branches inward and along the length of the tree'"'"'s trunk. The rotation of the branches is initiated by the rotation of the threaded inner core which is coaxially placed within the tree'"'"'s outer trunk shell. This rotational motion is translated into a linear motion along the threaded inner core by the restriction of the rotational movement of a threaded branch translator placed on the threaded inner core. The restriction is caused by branch extenders pivotally attached to the branch translator and passing through openings located on the tree'"'"'s outer trunk shell. The linear motion of the translator causes a multitude of pivotally attached branches radiating from the tree'"'"'s trunk to rotate inward and along the tree'"'"'s trunk. Thus, the diameter of the tree is reduced for easier transport and storage.
