Baby walker barrier

Apparatus for forming a barrier on a support surface to restrict movement of a baby walker on said support surface when the apparatus is engaged by said baby walker, said baby walker having a walker body and wheels, said wheels supporting said walker body a predetermined distance above said support surface, said apparatus including at least one elongated barrier element positionable on said support surface and rotatable relative to said support surface, said elongated barrier element including first wheel engagement means comprising an elongated cam element having a cam surface extending lengthwise along said elongated barrier element and slanting upwardly from said support surface when said elongated barrier element is positioned on said support surface for engagement by a wheel of said baby walker, first support surface engagement means including a fulcrum element positioned on one side of said cam surface and extending lengthwise along said elongated barrier element engaging said support surface to prevent sliding of said elongated barrier element relative to said support surface when said walker wheel engages said cam surface whereby engagement between said walker wheel and said cam surface causes rotation of said elongated barrier element about said fulcrum element, and first walker body contact means comprising an elongated protrusion positioned on a second side of said cam surface and spaced from said fulcrum element with the distance between said fulcrum element and said protrusion exceeding said predetermined distance, and said elongated barrier element rotating responsive to engagement of said first wheel engagement means by a baby walker wheel to bring said protrusion into contact with said walker body and jam said elongated barrier element between said support surface and said walker body to terminate movement of said baby walker relative to said support surface.
