Embodiment Construction

[0026] Figure 4 A schematic front view of a delineator 410 including a grooved region 416 is shown in . Delineator 410 includes a tubular body 412 having a first end 412a and a second end 412b and a base 414 . As a reference, a Cartesian x-y-z coordinate system is also included in this drawing. A delineator axis 413 parallel to the z-axis defines the longitudinal axis of the delineator.

[0027] The first end 412a of the body 412 is shown adapted to fit snugly within the opening of the base 414 . Alternatively, the end 412a may itself be configured as the base. The base, which may be of any known design, is of sufficient weight and / or has sufficient attachment mechanisms to the road or ground to maintain the upright posture of the delineator after installation. In some cases, the base may be integrally formed with the tubular body, while in other cases the base may be press-fit, glued, or otherwise permanently, semi-permanently, or removably attached to body 412 . If the...

Abstract

A traffic delineator comprises a tubular body having first and second ends, the first end being configured as a base or being adapted for affixing to a base. The delineator may also include a slotted region to enhance flexing of the tubular body in response to vehicle impacts. The slotted region may include slot(s) formed transversely in the tubular body. In some embodiments, the slot(s) may include one or more discrete slot, each of which may define a hinged section of the tubular body. In some embodiments, the slot(s) may include a continuous transverse slot having a helical configuration. In some cases, the slotted region may be disposed proximate the first end, and a second slotted region or other window region may be disposed elsewhere on the tubular body so as to expose a reflective sheet that may be applied to an inner core disposed within the tubular body.

Description

technical field [0001] The present invention relates generally to delineators for controlling the movement of vehicles on roads and the like. The invention also relates to related articles, systems and methods. Background technique [0002] Traffic delineators are well known. Delineation markers are generally used on or near roads or other paved or unpaved roads where cars, trucks, or other motorized or non-motorized vehicles travel. For the benefit of vehicle drivers, a series of delineators are often placed along a road, driveway or path to accentuate or enhance their visibility. figure 1 is an idealized perspective view of a road 110 along which a contour marker 112 is provided to mark the route or direction of the road. Delineation markers can also be used in construction areas to help drivers of vehicles who may not be familiar with the route to navigate the route. Perhaps because delineators can be used to direct or "channel" traffic in a given direction, they are ...
