Abstract

An artificial Christmas tree (10) which simulates a decorated real Christmas tree is disclosed comprising a base stake (26) for insertion in the ground, an upstanding trunk (12) having an enlarged diameter lower trunk portion (24) connected at the bottom to the stake (26) and terminating at its upper end in a smaller diameter upper trunk portion (30), a hoop (14) encircling the trunk (12) at the upper end of the enlarged diameter lower trunk portion (24), angularly spaced-apart spokes (16) connected between the hoop (14) and trunk (12) for holding them in concentric relation, upper guys (18) extending between the hoop (14) and the upper trunk portion (30), and lower guys (22) for connection between the hoop (14) and the ground to stabilize the hoop (14) and trunk (12). Intermediate guys (20) are connected between the hoop (14) and a point of the trunk (12) substantially midway between the spokes (16) and the top of the trunk. An omnidirectional star (50) having three half-star-shaped sections (52) arranged at 120° intervals is attached to the top of the tree (10), and presents a full star shape when viewed from any angle. Light strings (94) are looped between the hoop (14) and top of the trunk adjacent each of the upper guys (18), and garland is spirally wrapped around the tree from the top of the trunk to the hoop, and may also be draped as desired. At night, the illuminated tree appears to sparkle giving a jewel-like appearance. The artificial Christmas tree (10) is suitable for outdoor use, and the trunk (12) extends from the lowest simulated limbs of the tree (10) to the ground. The lower trunk (24) may be wrapped with a light string.
