Abstract
Abstract For baby strollers, particularly umbrella strollers, a device to prevent tipping comprising a pair of rearward extension bars. Each bar is adapted to extend rearwardly over or nearly over one of the rear wheels of the stroller. Each curves downwards so as to clear the wheel over or near which it extends and then curves to present a distal end section at least approximately parallel to the surface on which the stroller sits. Each bar is provided with a clamp by which it may be attached to the stroller. The clamp is adjustable to optimize tip prevention and loosenable so that the extension may be folded transversely for storage or transport.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
The combination of an umbrella type stroller having at least four wheels including two rear wheels and a vertical element substantially above each said rear wheel; and a pair of identical tip prevention bars, each said bar comprising: a proximal end adapted to be attached to said stroller and a distal end; a proximal end straight section, generally approximately horizontal; a middle section smoothly curved downwardly; a distal end straight section shorter than either said proximal section or said middle section, and being approximately horizontal; said proximal end of each said bar being provided with a clamp configured to loosenably attach to a said vertical element on said stroller, whereby each said bar may be selectively extended rearwardly of said stroller to prevent tipping or folded transversely said stroller for storage or transport.
Claim 2
Dependent Claim
