Abstract: A support frame having a plurality of wheeled assemblies, mounted at corners of the support frame, each wheeled assembly including a substantially identical mechanism for extending and retracting a respective wheel assembly. Each mechanism has a locking member which includes a locking portion for selectively engaging locking apertures on a rotatable member which rotatably supports the wheel assembly. Each mechanism also includes a grip, spaced from the locking member, to facilitate rotation of the rotatable member and the respective wheel assembly between extended and retracted positions when the locking portion is disengaged from the locking apertures. When each wheel assembly is in an extended position, the support frame is able to roll on a suitable surface. Each wheel assembly is also capable of being retained in a retracted position housed within a recess in its associated housing.

Abstract: An amusement device advantageous for use with an infant crib or the like. An arm slideably engages a mounting bracket which is formed to rigidly attach to a top rail of the infant crib. The arm includes a drive motor configured to rotate a snap fitting which releasably secures a support member having one or more novelty items connected thereto. The arm also houses a speaker, a light array, a night light, a processor and an array of switches. A platform, serving as a support for an infant, has a vibration device mounted on it. The switches are selectively activated to control the processor to selectively operate the speaker, the light array, the drive motor, the night light, or the vibration motor. The processor controls the light array and speaker to synchronize pulsation of the light array with a melody played by the speaker. The various functions are preferably programmed to turn off after an adjustable time interval.

Abstract: A child stroller and infant carrier system comprising a stroller having a frame. Generally parallel upstanding pylons are secured to the lower tubes adjacent to their upper ends with resilient locking fingers movable outwardoy from the pylon. An infant carrier with an upstanding front, back and sides is fabricated of a rigid material with a pivotable handle in an inverted U-shaped configuration extending upwardly from intermediate points on the sides thereof. The carrier has an aperture on each side positionable to releasably couple with the pylons to thereby selectively join the carrier to the stroller.
