  • Patent number: 5150874
    Abstract: An improved apparatus for mounting artificial tree branches to an artificial tree trunk. A series of bracket guideways, each bridged by a horizontal pin, are adapted for pivotal engagement each with a branch member for movement between stowed and operative positions. Each branch mounts a hinge piece adjacent to one end adapted for pivotal engagement with the horizontal pin as the branch moves between stowed and operative positions, the hinge piece suspending the branch radially from the tree trunk when in an operative position. Snaps secure the branch in a groove on the hinge piece to restrict movement of the branch about the bracket when in either a stowed or an operative position. Extended bracket guideways and a hinge piece back stop also assist in securing the branch to the hinge piece and restricting radial movement of the branch about the bracket.
