Abstract
Pavement markers are provided that are equipped with installation tabs which permit marker storage vertically and which permit hand holding of the individual markers during installation. After a marker is installed, each tab is breakable adjacent to the marker upper surface in response to an applied small bending force. The tabs overcome the problem of installing pavement markers upon hot tar.
Claims18
A pavement marker comprising
- a solid flattened body comprised of plastic and having
- a perimeter,
- a generally convex top, and
- a generally planar bottom;
- and
- tab means
- said tab means being integral with and outstanding from said top, and in inwardly spaced relationship to said perimeter,
- said tab means being cooperatively engagable at outer regions thereof by clamping between a thumb tip and at least one finger tip of a hand so that said body is supportable by compression force exerted between said thumb and said finger(s), said tab means being relatively rigid in the direction of said compression force, and
- said tab means also being brittle and breakable adjacent said top responsive to a relatively small bending force applied against said outer regions in a different direction from that in which said compression force is exerted.

A pavement marker comprising
- a solid flattened body comprised of molded thermoplastic and having generally convex top, a perimeter, and a generally planar bottom;
- and
- a pair of tabs, each one
- having a base end that is integral with said top and that is located inwardly spaced relationship to said perimeter and an opposed outstanding outer end region;
- each tab being in spaced relationship relative to the other thereof,
- each tab being engagable at said outer end region thereof with a different one of a thumb tip and a forefinger tip of a hand so that said body is supportable by compression force exerted between said thumb and said forefinger, said tab means being relatively rigid in the direction of said compression force, and
- being breakable at said base end adjacent said top responsive to a relatively small bending force applied against said outer end region in a direction generally normal to the direction in which said compression force is exerted.
