  • Patent number: 10755684
    Abstract: A sound producing device includes: a housing and carriage. The housing has a cylindrical interior surface with a helical tracking thread protruding therefrom. The cylindrical carriage has an opening in its exterior surface defining a helical shaped recess that receives and tracks along the helical housing thread. A squeaker may be secured within the carriage, so when air flows in a first direction through the housing, it emits sound, and the squeaker carriage is driven to track along the helical thread, causing the carriage to rotate and also translate in the first direction, according to a pitch of the helical thread. A frequency of the sound produced by the squeaker changes according to the carriage's translational movement, as it changes the dimensions of the sound-producing chamber. When air subsequently flows through the housing in the opposite direction, the carriage's motion is reversed, correspondingly changing the frequency of sound produced.

  • Patent number: 5727982
    Abstract: The action figure disclosed includes a mechanism for rotating an armor other appendage relative to its torso. The arm is activated by pivoting one leg toward another against the bias of a spring to pivot an internal lever that imparts linear movement in a follower. The follower includes a cam for engaging helical ribs on an arm shaft to translate linear motion of the follower to rotary motion in the arm shaft and arm. A ratchet on the follower prevents engagement with the lever while the spring returns the leg and internal lever back to their original positions to permit substantially continuous rotary movement of the follower.

    Abstract: An activity toy, having a spherical housing which is flattened at its poles so as to be supportable at two places on a support surface, has an elongated helical member which extends within the interior from one of the poles to the other. A bushing is fitted around the helical member and is sized so as to very lightly frictionally engage the helical member whereby when it moves along the longitudinal axis of the helical member, the friction between it and the helical member rotates it on the helical member. A collar is located around the bushing. The collar is free to spin independent of the bushing. However, during travel of the bushing along the helical member, the rotation of the bushing is communicated to the collar. The collar includes a plurality of axles which extend away from the collar, each of which carries an object on its end.

  • Patent number: 4480400
    Abstract: A bouncing toy having a base supported by four springs-attached balls to give the base a bounce while maintaining stability. Central to the base is another spring attached ball having a cylindrical upright member mounted thereon. Within the cylindrical member are a series of radially extending pegs arrayed spirally to form a helix. Mounted to the base and surrounding the cylindral member is a hollow shaft including a rotatable wheel mounted thereon, the wheel having a helix-structured shaft connected thereto which is disposed to engage the radially extending pegs. Movements of the central ball causes the pegs and shaft to engage resulting in rotation of the shaft and attached wheel. The up and down movement of the toy causes the wheel to rotate in opposite directions until the toy comes to a complete stop. Audio devices are arrayed in proximity to each of the supporting balls so that the movements of the balls creates an environment which actuates the audio devices rendering various tones as the toy bounces.
