  • Patent number: 8105664
    Abstract: An artificial decorative plant assembles multiple branches first which are then assembled with a main stem. Each branch is composed of a rod with resilience, a securing piece and multiple branch strips. The securing piece has two longitudinal sides and multiple clamping pieces alternatively staggered and extended from the two longitudinal sides respectively with multiple intervals and applied to wrap the rod. Additionally, multiple clamping attachments are extended from the two longitudinal sides inside the multiple intervals respectively so that each clamping attachment is between two adjacent clamping pieces to engage a corresponding branch strip with leaves. After completing assembly of the securing piece and the rod, the combination engages the main stem by a hook element on the rod. Because of such structure, it not only enhances the combinational strength but further improves efficiency of assembly convenience.

  • Publication number: 20100323129
    Abstract: A takedown artificial tree includes a plurality of flexible branches, each of the branches including a substantially straight, hollow main stem and a plurality of fronds extending from the main stem; a plurality of fixing brackets made of rigid material, each of the fixing brackets including a hollow cylinder and a hollow branching member obliquely upward extending from the cylinder; and a trunk made of metal, the trunk being frictionally inserted through the fixing brackets to serve as a support of the finished artificial tree. Base of the main stem of each branch can be inserted into the branching member for fastening. No assembly by a buyer is required. There is no worry of the branches falling onto the ground.
