  • Patent number: 4019751
    Abstract: A multipurpose infant's wheel chair having a rockable base with front and rear wheels which can be swung to engage ground or to be positioned so that the rockable base engages ground. Accordingly, the device is usable for rocking or rolling. The base also has a member positionable selectively to engage ground so that the base is held stationary with respect thereto. A chair seat and back rest hingedly secured to each other are carried on the base and selectively positionable so that an infant may be seated upright or in the reclining position. Thus, the invention is capable of a variety of uses in that it can be used as a rocking chair or rocking horse, or as a stroller, dependent on the selected position of the wheels. The invention is also usable as a bed for an infant with the base held stationary so as to be non-rollable and non-rockable. Alternatively, the base may be retained in rockable position with the back rest reclining so that a child may be rocked to sleep.
