Embodiment Construction

[0037] The pavement marking according to the present invention is in Figures 1 to 12 identified generally by reference numeral 10 . Pavement marker 10 includes a base 12 , a bottom cover 14 , and front and rear lenses 16 and 18 . The base 12 is integrally molded from thermoplastic material and includes a bottom 20 ( figure 2 most clearly shown in ) and the opposite top 22 (figure 1 most clearly shown in ). Top 22 is formed with front and rear lens recesses 26 and 28 for receiving front and rear lenses 16 and 18, respectively. Lenses 16 and 18 may be secured in respective lens recesses 26 and 28 by adhesive or mechanical attachment. Other aspects of the shape and function of the top 22 of the base 12 and the lenses 16 and 18 are not critical to the first embodiment of the invention and are not further described here. However, the construction and function of the pavement marking top is more relevant to the second embodiment of the invention and will be described in more d...

Abstract

A pavement marker has a base having at least one opening formed therein. A groove is formed in the base substantially adjacent the opening. The pavement marker further includes a cover for covering the opening in the base. The cover is formed with at least one energy directing rib configured for nesting with the groove in the base. The cover is ultrasonically welded to the base so that the energy directing rib melts and integrally fuses to portions of the base adjacent the groove.

Description

technical field [0001] The present invention relates to a pavement marking which reflects and / or emits light to identify selected areas of the road surface traveled. Background technique [0002] Pavement markings are affixed to or in the roadway to help guide drivers along their preferred lane of travel. A typical pavement marking includes a number of discrete components selected to perform specific functions. For example, a typical pavement marking may include a base and at least one light emitting or reflective panel mounted to the base so as to be clearly visible to drivers approaching the pavement marking. The base of the surface mounted pavement marking may be molded from a thermoplastic material and may include a bottom surface configured for securing to a road surface. The base may also include a top surface configured to receive a light emitting and / or reflective panel. [0003] Thick injection molded products take a long time to cure and introduce the possibilit...
