Attachment for a ground traversing device and/or a ground traversing device

An attachment for a ground traversing device comprising a bracket engageable on a handle of a ground traversing device, a substantially U-shaped axle pivotally mounted at its central portion on said bracket with the arms of the U-shaped axle depending therefrom, roller means mounted on the free ends of the arms of said axle to engage the ground, stop means to limit pivotal movement of said axle to a range between forward and rearward positions, said stop means comprising a pair of substantially U-shaped brackets each formed by a base and two spaced arms extending from said base pivotally affixed one to the other by a pivot pin extending through aligned apertures in said bracket arms and arranged so that pivoting of one bracket relative to the other is limited by engagement of at least one arm of one bracket with the base of the other said bracket, one of said brackets having said axle mounted thereon and the other said bracket being mountable on said handle, and biasing means to resiliently urge said axle into said forward position, said attachment being engageable on said handle so that when said axle is in said forward position said attachment supports said ground traversing device on the ground and when said axle is in said rearward position said attachment does not support said ground traversing device and means to releasably retain said axle in any position between said forward and rearward position.
