ABSTRACT:
A collapsible adapter is used to convert an infant stroller for use on irregular terrain or for use while running or jogging. The adapter holds an accommodated stroller on supports, lifting the wheels of the stroller off the terrain and substituting its own wheels for their function. The adapter has a light weight frame which folds at lockable hinges, to make a compact configuration for storage or transportation when the adapter is not in use with a stroller. When unfolded, the frame locks into the unfolded configuration. When in use, the adapter and an accommodated stroller are pushed using the accommodated stroller's existing handle. The adapter's hinges are arranged so that the weight of the adapter and the weight of a stroller with which it is used both act so as to prevent unintended collapse of the adapter. Simple attachment means provide for secure attachment of a stroller to the unfolded adapter. An attachment clamp acts to pull the accommodated stroller in a forward direction into slots or against projections of the adapter's stroller support. When used with a collapsible stroller, the adapter's attachment means act to prevent the stroller from collapsing. A doubly-hinged handle near the center of gravity of the unfolded adapter provides for convenient carrying of the folded adapter. When equipped with a quick-release front wheel, the adapter may itself be adapted for towing behind a bicycle.
