  • Patent number: 5305705
    Abstract: A traffic marker body defined by a conical spiral arm (16) mounted for collapse into a flat core held in matching recess (22) in a base (12) by means of an automatic locking mechanism including a latch member (24) with friction reducing rollers (34, 36) to facilitate lateral travel along cam guide surfaces (38, 40, 48, 50) into alignment with a latch engaging member including a slot (46) to lock the traffic marker body (14) into a collapsed condition (FIG. 1). The adjacent segments of the spiral arms (16) are spaced sufficiently for air passageways passing through the body (14) for improved stability and to enhance visibility of elongate reflector members (54) woven in and out between adjacent segments of a spiral arm (16) with reflective surfaces on both sides for creation of visual depth and a twinkling effect for enhanced visibility.
