ABSTRACT:
A car seat/stroller has a rigid tubular telescoping handle assembly and wheel bracket assembly which are fitted thereto in a manner which does not interfere with normal operation of the device as a car safety seat, but rather enhances the seat's safety and convenience. The handle assembly consists of a series of telescoping sections of tubing. Two holes are drilled at a diagonal angle into an infant car seat at respective top corners of the seat's sides, and further through respective flares at armrest portions of the seat. A tubular sleeve is inserted into each hole and is fed through to an underside of the flare. A clamping adjustment device is then affixed to one or both tubular sleeves at an upper portion thereof. Tubular L-shaped upper handle members are inserted into the tubular sleeves. The tubular L-shaped upper handle members are joined via a connecting tube having tensioning wires, each of which is fastened at a first end to an end stop in the connecting tube and at a second end to a second end stop in the tubular L-shaped upper handle member. A flat bar bracket having a first set of wheels thereon is affixed to a bottom portion of the seat in a manner whereby the wheels extend just below the lowermost portion of the seat and do not extend substantially beyond the outer periphery of the seat's housing. A retractable pivoting support on the car seat's bottom portion is modified by drilling a hole therethrough and inserting an axle on which a secondary set of wheels is mounted.
