Abstract: Method for making a wheel composed of a rigid plastic inner section forming the wheel hub and rim and a resilient plastic tire section encircling the rim. A key formed integrally with the rim extends radially outward therefrom and interlockingly projects into the tire so as to mechanically connect the tire to the rim all around the wheel. The key can be formed with axially extending portions spaced radially outboard of the rim and terminating flush with the outer surface of the tire section so as to provide colored side wall decorations at one or both sides of the wheel. A method of molding the tire directly onto the discoid section is also disclosed.

Abstract: A child's electric swing includes a pre-wound wind-up mechanical escapement type motor having spring-biased retainer and driving pawls, the latter being connected to a pivotally mounted hanger supporting the swing seat. The pawls engage a mainspring-driven ratchet wheel which periodically impulses the driving pawl to maintain the seat in oscillation. The mainspring is rewound periodically by rotating the ratchet wheel in the opposite direction by a battery-operated motor through a gravity-operated one-way clutch after the ratchet wheel rotates only about 180.degree. so that the prewound spring is always under tension. Also the pawls are moved out of engagement with the wheel during such rewinding to eliminate noise and drag on the wheel.

Abstract: A canopy for a bi-directionally folding stroller has a pair of side frame members whose corresponding first ends are pivotally connected to the stroller pusher handles and whose opposite ends are normally held apart by an articulated frame member. Flexible sheet material is stretched between the side frame members and retained there by lateral fingers projecting from the side frame members and engaging in pockets in the sheet material. Triangular flaps of sheet material extend beyond the side frame members. These can be connected together at the underside of the canopy or to points adjacent the pusher handles to partially enclose the sides of the stroller.
