  • Patent number: 4659597
    Abstract: An artificial Christmas tree is constructed in a manner to be transformable between a compact storage state and an erected state. The tree has an elongated trunk and a series of branch assemblies spaced upon its trunk. An upper collar is slidably disposed upon the trunk in association with each branch assembly. When the upper collar is moved downwardly, lever arms pivotably attached to the collar causes branch elements to move away from the trunk and assume a tree-like upwardly angled disposition.
