20100003079 | Method of Installing Depressible Pavement Marker - A retractable, reflective pavement marker for delineating traffic lanes of roadways and a method of installing the same that provides improved protection from potentially damaging vehicle tires, snowplows, and environmental conditions. The marker incorporates a reflector assembly mounted to a piston that is depressible within a housing. A biasing means returns the reflector assembly to its normal position above the road surface. A compliant adhesive cooperates with an adhesive lock formed between the housing and the opening to ensure that the marker is reliably retained within the pavement. The adhesive and a chamfered opening prevent pavement spalling due to external forces. The housing includes a removable retainer through which the piston is reciprocally received. The retainer includes a plurality of coarsely pitched lead-in threads that cooperate with a threaded housing. Multiple lead-in threads provide sufficient thread engagement, while substantially decreasing the number of rotations to achieve full engagement. | 01-07-2010 |
20110150569 | LOW PROFILE BARRIERS HAVING ATTACHED MOLDED PINS - A barrier assembly includes a barrier having an interior surface and an opposing exterior surface extending between a first end and an opposing second end. The interior surface bounds a chamber that is adapted to receive a ballast. The barrier also has an internal sidewall extending between top and bottom surfaces of the barrier so as to bound a passage extending completely through the barrier between the top and bottom surfaces. The barrier assembly also includes an elongated coupler extending down through the passage and projecting below the bottom surface of the barrier. A means for securing the coupler within the passage is formed on or attached to the coupler. The means for securing the coupler within the passage prevents the coupler from being removed from the passage while allowing the coupler to freely rotate within the passage. | 06-23-2011 |
