ABSTRACT:
A treehouse play set for use with action figures includes a tree-shaped base having a hollow trunk portion and a treehouse platform attached to the trunk portion, and further includes an elevator which is slidably movable on the exterior surface of the trunk portion between a first lowered position wherein the elevator is adjacent a supporting surface and a second raised position wherein the elevator is generally co-planar with the treehouse platform. The play set further includes a tree-growing mechanism disposed within the trunk portion to simulate growing action of the tree when the elevator is moved from the lowered position to the raised position. The tree growing mechanism includes a plurality of elongate branch members which are attached to the top portion of a piston which is slidably received within the trunk portion of the base. The piston is slidably movable within the trunk portion between a first lowered position wherein the branch members are generally disposed within the trunk portion, and a second raised position wherein the branch members extend upwardly and outwardly from the upper end of the trunk portion. The elevator is coupled to the piston wherein movement of the elevator between the lowered and raised positions causes corresponding movement of the piston between the lowered and raised positions.
