Grass guard device

Claim 1

A grass guard device, comprising, in combination: a supporting post member adapted to be forced into the ground; the supporting post member carrying, adjacent its upper end, a resiliently biased laterally-extending arm means adapted to extend over the edge of an associated roadway surface even though the supporting post member is thrust into the ground at a location aside of said roadway surface; the supporting post member and the arm means providing that if the said arm means is engaged by a vehicle on said roadway surface adjacent the edge thereof, the said arm means will audibly warn the driver of the vehicle of the adjacent proximity of the edge limit of the said roadway surface, and thus warn the driver to exert some driving maneuver to the vehicle to prevent it from being driven off the edge of the roadway surface; the audible sound being produced by the said engagement of the arms means with a component of the vehicle such as its bumper, fender, tire or paneling, either by the relative movement thereof by the engagement thereof as the below-mentioned return-bias or return-movement of the arm means causes it to forcefully encounter one of said vehicle-components; in which relatively movable means of the arm means and/or the supporting post member accommodates a substantial movement of the said arm means without altering the engagement of the supporting post-member and the ground; and in which a relative resilient deformation, of the arm means and/or the supporting post member, occurring as an incident to movement of said arm means, causes a return-bias of the arm means and subsequently a return movement thereof subsequent to release of engagement thereof of the portion of the vehicle which had caused said movement; in a combination in which the said supporting post member and the said arm means are integrally connected in a unitary body member, which is of sufficient flexibility to provide the aforesaid relatively movable means resiliently accommodative of the said arm means movement without altering the ground engagement of the supporting post-member.
