Abstract: A toy ball is formed from two shells and a pair of lock mechanisms 220. During construction, the shells, which may be hemispherical, are mated together and then the lock mechanisms are secured to the shells to form a substantially smooth-surfaced sphere. The lock mechanisms provide a redundant locking feature to hold the two shells together to form the toy ball.

Abstract: The present invention provides an infant entertainment device and a support assembly for positioning the entertainment device in view of an infant. The support is reconfigurable between an expanded configuration and a collapsed configuration. The entertainment device is responsive to actuation of a motion detector coupled to the entertainment device.

Abstract: A stackable articles toy including a number of articles that can be coupled together or coupled to a support and which also generates sensory output upon interaction by the infant with the toy to prolong the infant's enjoyment of the toy.

Abstract: A toy for promoting gross motor development includes a base and a support communicating with the base. The toy also includes an activity area disposed on the support above the base. The activity area is attractive to an infant and encourages the infant to reach up to the activity area by pulling up from a seated position to a standing position using handles or grips disposed on the support or the activity area. The toy also includes sensory output generators configured to encourage the infant to pull up using the handles or grips to reach the activity area. The toy further includes a track coupled to the support and positioned between the top activity area and the base. The track is configured for guiding an object between the top and the base. The top activity area, track, and gripping regions interact to provide an enjoyable and stimulating toy for the child while at the same time promoting the child's gross motor development.

Abstract: A toy power tool is shown having a tool-holding housing and a handle housing rotatably connected at interfacing surfaces inclined to the central axes of both housings. Relative rotation of the housing about a transformation axis perpendicular to the inclined interfacing surfaces transforms the tool from one desired configuration to another. A 180.degree. rotation of the tool-holding housing relative to the handle housing transforms the tool between a straight configuration with the central axes of the housings being aligned, and a L-shaped configuration with the central axes of the housings being at right-angles. Detents between the interfacing surfaces position the housings at the desired configurations, and double as switches that are connected to a sound producing circuit on a printed circuit board mounted parallel to the interfacing surfaces. An internal gear mechanism converts linear input motion to the relative rotary motion of the housings.
