Abstract: A wired flying model airplane manipulation rack for manipulating the flying of a wired model airplane, including a swivel control mechanism having a U-frame turned about a metal axle horizontally through 360.degree. and a swivel member turned within the U-frame vertically over 180.degree., a traction mechanism adapted to change the direction of the applied force of the operator, for permitting the flying model airplane to be controlled to fly horizontally through 360.degree. and turned in different directions.

Abstract: An undulating display includes a rigid track, a pair of linking members secured to the track, a first pivot member having first pivot axis and a second pivot axis, and a second pivot member pivotally supported on the second pivot axis of the first pivot member. The pair of linking members is secured to the second pivot member. The display also includes an drive mechanism for pivoting simultaneously the second pivot member about the second pivot axis and the first pivot member about the first pivot axis thereby to produce undulating motion of the track.

Abstract: An action toy for young children comprising a base that defines a pathway, and motor means on the base connected to a primary mobile object in the form of a personified animal or vehicle such as a toy shark for advancing the object forwardly along the pathway. Caming surfaces are spaced along the pathway and a matting caming surface is provided on the primary object. The caming surfaces are arranged and designed so that they engage and cause the primary object to raise upwardly at each pathway caming surface and then lower back down between pathway caming surfaces. This provides intermittent up and down movement of the primary object as it moves forwardly. Such movement could simulate the opening and closing of the jaws of the shark. Secondary objects such as small fish may also be provided for movement along the pathway; They may appear to be "swallowed" by the shark when it reaches one of them.
