Abstract: A line marker apparatus for visibly marking the location of a utility line and the like has a tube disposed vertically in the ground. A locking ring is disposed on the tube and has a plurality of locking fingers extending from the ring. The locking finger are bendable in towards the tube. A cap or marker is removably coupled to the locking ring. The cap has an open end for receiving the locking ring and a protrusion extending into contact with the locking finger for forcing the locking finger in towards the tube. Ribs may be formed on an inner surface of the fingers to prevent the locking ring from rotating on the tube. A slot may be formed in the locking ring or cap to vent the cap. An indentation may be formed in the cap to receive indicia.

Abstract: A highway delineator device comprising an elongate tube having a bottom end, a top end, an inside surface, and an outside surface, and configured for use as a highway delineator. The bottom end of the tube comprises means for connecting the tube to a base support in such a manner that the tube is in a vertical configuration, and the top end of the tube having at least three different cross-sections comprising (i) a top cross-section flattened together with opposing inside surfaces sealed together to fully close the top end of the tube and having opposing outside surface in parallel relationship for receiving a top edge of reflective material without curvature, (ii) an intermediate cross-section having an elongate gap extending between the opposing inside surfaces, said outside surfaces along the gap being slightly arcuate to provide a flattened surface for receiving a lower section of reflective material with moderate curvature, and (iii) a lower cross-section having a circular configuration.

Abstract: A tamper resistant sign for flush mounting to a wall or substantially flat surface comprises an elongate, one piece, extruded or pultruded frame. The frame has a back wall and a pair of ribs extending backwardly from respective lateral side edges of the back wall. A pair of open sided channels are positioned along the side edges of the frame. The open sides of the channels face each other and have a clear plastic faceplate positioned therebetween, with the opposite lateral sides of the faceplate being received longitudinally within the respective channels. Molded end caps are provided that seat firmly against the back wall and channel of the frame to close the opposite ends of the sign. The end caps fit securely and tightly in the channels and against the back wall of the frame.

Abstract: A delineator device having high visibility and utility for attachment to a paving surface such as a median curb or other dividing area between two lanes of traffic. The device includes an integral base member and vertical support member having a top and a bottom end and intermediate section including an elongated concave-convex structure. The bottom end of the vertical support is coupled to an upper face of the base to provide support for an attached horizontal member at the top end of vertical support member. This horizontal member includes top and bottom edges and an intermediate section which is also of concave-convex structure. A receiving base is provided for insertion of a projection tab section which extends downward from the base member. Locking flanges are attached to the tab to enable the device to be secured in its inserted position.
