Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
In a reflector-type lane marker comprising a base cup with a bottom and upright rim forming a chamber open at the top of the rim, a resilient elastomeric diaphragm removably secured to the periphery of said rim and means for sealing said diaphragm to said rim to withstand passage of air and water, an upright traffic lane lens assembly and means for mounting said lens assembly in the central portion of said diaphragm and external to said chamber, the improvement comprising mounting said lens assembly in a plastic retaining member having a tensile strength of at least 5,000 psi and a flexural modulus of elasticity of at least 300,000 psi at 73*F. and 50 percent relative humidity, said retaining member having a channel for receiving said lens assembly and a plurality of titted angled projections on both sides of said channel, cooperatively molded into said elastomeric diaphragm.
