  • Patent number: 5312284
    Abstract: A toy computer includes a keyboard housing and a monitor housing pivotally secured by a hinge coupler. A depressible keyboard unit is pivotally supported by the keyboard housing and is coupled to a movable slider within the interior of the keyboard housing. A return spring is coupled to the slider and is operative to pivot the slider such that a ratchet engaging tooth is raised to its engagement position in the absence of a keyboard unit stroke. An endless belt display utilizes a cylindrical lens element array together with a segmented image formed on the endless belt to provide apparent motion of the image as the endless belt is moved. A ratchet coupling system is coupled between the slider and the movable belt to provide incremental belt motions in response to each keyboard stroke.

  • Patent number: 4227326
    Abstract: An amusement device for use by children both for entertainment as well as a coordination aid. The device comprises a plurality of thin essentially similar segments, each segment pivotally engaging adjacent segments in snap-in relation. The pivotal engagement enables rotation of one segment with respect to an adjacently engaged segment through a predetermined angle. Locking means are formed into the segments preventing translation of one segment with respect to another when such segments are engaged. When connected in the form of an open belt, the device may be manipulated in various entertaining manners, and upon articulation, the impact of adjacent segments produces a slapping sound for additional amusement. When the free ends of the belt arrangement are engaged to form a closed loop, two segment stacks are created. Back and forth manipulation of each segment stack causes individual segments to move from one stack to the other.
