Abstract

An artificial Christmas tree adapted to hang from a support structure such as a hook attached to the ceiling of a room or a center post during the Christmas season and to be quickly and easily collapsed and placed in a box, while still decorated with ornamentations such as colored balls, electrical lights and garland, for storage purposes, during the non-Christmas seasons. The collapsible artificial tree comprises a plurality of circular, concentric, limb sections connected together through flexible suspension means, each limb section being assembled in spaced-apart relationship and being of different external diameters. When assembled concentrically through use of the flexible suspension means, the limb sections gradually increase in diameter along an axis common to all of the limb sections with the limb section having the largest diameter being at the bottom of the tree and the limb section having the smallest diameter being near the top of the tree when the tree is suspended in its display position. This arrangement provides the tapering effect generally exhibited by trees of the fir, pine and spruce families. The height of the tree is determined by the number of limb sections making up the tree. The height of the tree can be readily adjusted by adding or removing limb sections.
