Abstract
Abstract A pavement marker reflector member having a shell-like body of synthetic resin material, a filler material within the shell-like body and a base plate affixed to the shell-like body and including lowermost surface portions establishing a basal support for the reflector member. The reflector member may be affixed to a base member, in which case the lowermost surface portions of the base plate engage corresponding portions of the base member in a pavement marker assembly.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
128 words
A pavement marker for establishing a marking visible from an oncoming vehicle on a roadway surface, said pavement marker comprising: a shell-like body of synthetic resin material, said shell-like body having an upper surface, a lower edge and at least one light-transmitting portion including an obverse light receiving surface between said upper surface and said lower edge; a filler material within said shell-like body for reinforcing said shell-like body against forces applied externally by contact with the oncoming vehicle; a lower surface adapted to face the roadway surface; and a base plate including portions embedded within the filler material for affixing the base plate to said pavement marker coextensive with essentially the entire lower surface and including lowermost surface portions establishing a basal support for the pavement marker.
Claim 2
Dependent Claim
128 words
A pavement marker for establishing a marking visible from an oncoming vehicle on a roadway surface, said pavement marker comprising: a shell-like body of synthetic resin material, said shell-like body having an upper surface, a lower edge and at least one light-transmitting portion including an obverse light receiving surface between said upper surface and said lower edge; a filler material within said shell-like body for reinforcing said shell-like body against forces applied externally by contact with the oncoming vehicle; a lower surface adapted to face the roadway surface; and a base plate including portions embedded within the filler material for affixing the base plate to said pavement marker coextensive with essentially the entire lower surface and including lowermost surface portions establishing a basal support for the pavement marker.
Claim 3
Dependent Claim
22 words
The pavement marker of claim 1 wherein the base plate overlaps and is juxtaposed with the lower edge of the shell-like body.
Claim 4
Dependent Claim
39 words
The pavement marker of claim 2 wherein the lower edge of the shell-like body extends around the entire periphery of the lower surface and the base plate overlaps and is juxtaposed with the lower edge around said entire periphery.
Claim 5
Dependent Claim
23 words
The pavement marker of claim 2 wherein the lowermost surface portions of the base plate are coplanar and establish a planar basal support.
Claim 6
Dependent Claim
42 words
The pavement marker of claim 4 wherein the base plate includes an undulate cross-sectional configuration, said lowermost portions being located at the lowermost part of the undulate configuration and said embedded portions being located at the uppermost part of the undulate configuration.
Claim 7
Dependent Claim
26 words
The pavement marker of claim 7 wherein the base plate includes a plurality of apertures located at the uppermost and lowermost parts of the undulate configuration.
Claim 8
Dependent Claim
33 words
The pavement marker of claim 6 wherein the apertures located at the uppermost parts of the undulate configuration are larger than the apertures located at the lower most parts of the undulate configuration.
Claim 9
Dependent Claim
237 words
A pavement marker assembly for establishing a Marking visible from an oncoming vehicle on a roadway surface, said pavement marker assembly comprising: a base member of relatively high strength material, such as a metal, adapted to extend in a direction which will be parallel with the roadway surface when the base member engages the roadway surface; said base member having a lower surface adapted to be affixed to the roadway surface, and an upper surface, said lower surface having an area sufficient to enable the base member to withstand contact with oncoming vehicles without failure or detachment from the roadway; a reflector member including: a shell-like body of synthetic resin material, said shell-like body having an upper surface, a lower edge and at least one light-transmitting portion including an obverse light receiving surface between said upper surface and said lower edge; a filler material within said shell-like body for reinforcing said shell-like body against forces applied externally by contact with the oncoming vehicles; a lower surface adapted to face the roadway surface; a base plate including portions embedded within the filler material for affixing the base plate to said pavement marker coextensive with essentially the entire lower surface and including lowermost surface portions establishing a basal support for the pavement marker; and means for affixing said reflector member to the base member for selective removal and replacement of the reflector member without destruction of the base member.
Claim 10
Dependent Claim
237 words
A pavement marker assembly for establishing a Marking visible from an oncoming vehicle on a roadway surface, said pavement marker assembly comprising: a base member of relatively high strength material, such as a metal, adapted to extend in a direction which will be parallel with the roadway surface when the base member engages the roadway surface; said base member having a lower surface adapted to be affixed to the roadway surface, and an upper surface, said lower surface having an area sufficient to enable the base member to withstand contact with oncoming vehicles without failure or detachment from the roadway; a reflector member including: a shell-like body of synthetic resin material, said shell-like body having an upper surface, a lower edge and at least one light-transmitting portion including an obverse light receiving surface between said upper surface and said lower edge; a filler material within said shell-like body for reinforcing said shell-like body against forces applied externally by contact with the oncoming vehicles; a lower surface adapted to face the roadway surface; a base plate including portions embedded within the filler material for affixing the base plate to said pavement marker coextensive with essentially the entire lower surface and including lowermost surface portions establishing a basal support for the pavement marker; and means for affixing said reflector member to the base member for selective removal and replacement of the reflector member without destruction of the base member.
Claim 11
Dependent Claim
23 words

Claim 12
Dependent Claim
40 words
The pavement marker assembly of claim 9 wherein the lower edge of the shell-like body extends around the entire periphery of the lower surface and the base plate overlaps and is juxtaposed with the lower edge around said entire periphery.
Claim 13
Dependent Claim
24 words
The pavement marker assembly of claim 9 wherein the lowermost surface portions of the base plate are coplanar and establish a planar basal support.
Claim 14
Dependent Claim
43 words
The pavement marker assembly of claim 11 wherein the pase plate includes an undulate cross-sectional configuration, said lowermost portions being located at the lowermost part of the undulate configuration and said embedded portions being located at the uppermost part of the undulate configuration.
Claim 15
Dependent Claim
27 words
The pavement marker assembly of claim 12 wherein the base plate includes a plurality of apertures located at the uppermost and lowermost parts of the undulate configuration.
Claim 16
Dependent Claim
33 words
The pavement marker assembly of claim 13 wherein the apertures located at the uppermost parts of the undulate configuration are larger than the apertures located at the lowermost parts of the undulate configuration.
