Claim 1
Independent Claim
254 words
A vehicle position indicator apparatus to provide an audible signal upon a predetermined positioning of a vehicle with respect to said apparatus wherein said apparatus comprises, a box-like case means including side walls, a top wall and a bottom wall, and a contact antennae means secured within said case means and projecting vertically upwardly and outwardly of said top wall of said case a predetermined distance for engagement with said vehicle, and a speaker means positioned in said case for emitting an audible sound upon said contact antennae completing an electrical circuit, and switch means positioned proximate said antennae within said case to complete said circuit upon deflection of said antennae by said vehicle, and wherein an on/off switch means positioned through one of said side walls of said case means enables selective completion of said circuit upon contact of said antennae with said switch means, and wherein a DC battery is positioned within said case means for providing energy to said electrical circuit, and wherein said switch means comprises a 360 degree encircling ring about said antennae for enabling contact of said antennae with said switch means, and wherein a rubber-like cover boot portion formed about said antennae means externally of said case means and in contact with said case means for containing sparking effected by completion of said circuit within said case means, and wherein friction-like feet are positioned downwardly from said bottom wall and externally of said case means to maintain said positioning of said apparatus on a horizontal support surface.
