Total Claims: 6
Claim 1
Independent Claim
200 words
A bicycle distance safety device attachable to bicycles for indicating a minimum safe distance to be maintained from inexperienced bicycle riders, comprising: an elongated vertical member having a top end and bottom end, said bottom end having an aperture therethrough and including means for attaching said vertical member to the rear portion of a bicycle frame with said top end extending substantially above the bicycle; over end of an arm member connected between the ends of said vertical member and the other end thereof connected to the bicycle; a cross member having a base end and distal end, said base end having means for attaching said cross member to the top end of said vertical member with said distal end horizontally extending outwardly from the side of said bicycle a predetermined distance indicating a minimum safe distance to be maintained from the bicycle; and, indicator means on the distal end of said cross member for indicating the recommended minimum distance to be maintained in passing a bicycle equipped with said safety device, said safety device being fabricated predominantly of a lightweight material to minimize interference of said safety device with the balance of the bicycle to which it is attached.
