Each of the pair of elongated skis circumscribe a pair of upwardly facing wheel-engaging wells at opposite fore and aft ends thereof, for receiving and containing a pair of fore and aft registering wheels from both axles of a two axle pushchair. A pair of elongated elastic cables are each anchored at both ends thereof to front and rear portions of a corresponding ski intermediately of the wells thereof. A pair of hooks are each slidingly carried along a corresponding elastic cable and releasably interconnect the elastic cable to the pushchair frame in such a way that the corresponding ski is movable between a first, operative, ground-engaging position, in which each pair of fore and aft registering wheels engage a corresponding ski well and are biased thereagainst under the resiliency of the elastic cable, and an inoperative, ground-clearing position, in which the ski releases the corresponding registering fore and aft wheels and extend generally above the latter.

A runner assembly for use over snowy grounds with a child\s stroller, the stroller including an open rigid frame having two pairs of laterally opposite fore and aft legs with each leg carrying a ground-engageable rotatable wheel, said runner assembly comprising: (a) an elongated runner member, defining a pair of opposite front and rear wheel support surfaces for releasably supporting the front and rear wheels respectively of one said pair thereof; (b) an elongated elastic member, defining first and second ends; (c) anchoring means, for anchoring each said first and second ends of the elastic member to front and rear anchoring points of said runner member, said front and rear anchoring points being adjacent said front and rear wheel support surfaces respectively and being located therebetween; and (d) a hook member, being engaged to an intermediate section of said elongated elastic member and adapted to engage an upper frame part of said stroller frame which generally overhangs said runner member, whereby the runner member is continuously biased upwardly; wherein said runner member is movable between a first ground-engaging operative position, in which said runner member front and rear support surfaces are biased by said elastic member for abutting against and to support said front and rear wheels respectively, and a second ground-clearing inoperative position, in which said elongated runner member is both laterally and upwardly offset from the first operative position such that said front and rear wheel support surfaces are oriented upwardly, whereby said runner member maintains a stable ground-clearing position.
