Abstract: A collapsible construction set comprises a plurality of parts, each of which includes at least one integrally formed connector. A plurality of connector designs are provided. A first design includes a tapered receptacle and a stabilizing pin at the center of the receptacle. A second design includes a tapered end which fits in the receptacle and a hole which receives the stabilizing pin. A third design includes a ledge which forms a recess, and a fourth design includes a hook which engages the ledge and extends into the recess. The ledge of the third design is preferably formed adjacent the receptacle of the first design, and the second design preferably also includes at least one flange which overlies and holds a hook of the fourth design. To dismember the parts of a structure, a tapered end is moved out of the tapered receptacle until the stabilizing pin disengages from the hole, and then all of the parts of the structure topple.

Abstract: Actuating linkage contained within each arm and hand of the doll causes the three middle fingers of either hand to be flexed from an extended relation to a clenched condition when the arm for that particular hand is raised. When the arm is lowered, then the middle fingers are automatically unclenched. The clenching action is independent of whatever degree of wrist rotation may exist.

Abstract: A doll having a movable head, and articulated appendages movably attached to the doll's torso. An actuator and a gear transmission system are operatively connected to one of the doll's arms, for imparting incremental movement to the arm. The transmission can be placed in gear, or taken out of gear, by manually rotating the doll's head. By placing the transmission in gear and manipulating the actuator, the transmission is activated so that the doll's arm, and if desired, a light load placed in the doll's hand, can be slowly raised to an elevated position. In addition, simulated battery pack inserts are positioned in one arm, a flexible skin-like covering stretchably fits over such arm, and a wide-angle lens is positioned in the doll's head.
