Abstract
A road delineator includes an upright sidewall having circular cross-section, and an outwardly extending support flange at a lower end for standing the apparatus in an upright attitude. An upper end of the sidewall engages an elongated donut-shaped rim defining a vertical aperture. A mushroom shaped, and upwardly directed, tie-on terminal is mounted within the vertical aperture. A circular weighting member engages with the support flange for holding the delimiter in the upright attitude. A warning tape may be strung between plural of these road delimiters to form a hazard boundary.

- The prior art teaches plastic road delineators with handles, but these are designed as assemblies of several parts, costly to assemble. However, the prior art does not teach a delineator as a unitary molded part with a hand graspable rim and a tape-engaging terminal mounted within the rim for protection thereof. The present invention fulfills these needs and provides further related advantages as described in the following summary.
- The present invention teaches certain benefits in construction and use, which give rise to the objectives described below.
- The present invention teaches a road delineator, which includes an upright sidewall having circular cross-section as either a cylindrical or a cone, and at a lower end thereof, an outwardly extending support flange for standing the apparatus in an upright attitude.

- A still further objective is to provide a delineator with a hand graspable upper rim and a mushroom shaped tape tie-on.
- A further objective is to provide such a delineator formed as a cone for improved stability when placed on a surface in an upright attitude.
- Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
- The accompanying drawings illustrate the present invention. In such drawings:
-
FIG. 1 is a perspective view of a first preferred embodiment of the present invention having a cylindrical body; -
FIG. 2 is a perspective view of a second preferred embodiment of the invention having a cone shaped body; and -
FIG. 3 is a perspective view thereof showing how plural units of the invention may be connected by crown-control tape engaged with the units. - Road delineators, such as this invention, are used for traffic control. They are commonly formed of a cylindrical plastic upright portion that may be colored highway orange, for example, and have a weighted detachable base for stability. Typical road delineators are approximately 42″ high and 4″ in diameter, and are equipped with reflective bands for day or night traffic control. Thus, they are distinguished from substantially smaller common traffic road cones that are primarily used for temporary traffic control. Because of the weighted base, a road delineator will typically remain in place if hit by a passing car, whereas a road cone will be overturned.
- The above-described drawing figures illustrate the invention, a soft and pliable molded
plastic delineator apparatus 10 having anupright stand 20 with, at a lower end thereof, an outwardly extendingsupport flange 30 for stabilizing thedelineator 10 in an upright and stable attitude. In one embodiment, the stand may not have theflange 30, but instead be wedged into a base 70 as is shown inFIG. 1 . The upper end of thestand 20 is integral with aframe 40 which extends upwardly therefrom and preferably is in the shape of an elongated donut-shaped rim as shown inFIGS. 1-3 , and defines anaperture 42 which is ideal for being grasped by a hand for ease of placement from, and pickup onto, a truck by a mounted worker. An upwardly directed, tie-on terminal 50 is mounted within thevertical aperture 42 as shown in the figures so that it is easily addressed yet is secure from being damaged as it is surrounded by theframe 40. - In one embodiment, the
upright stand 20 is generally cylindrical as shown inFIG. 1 . The sidewall preferably provides plural, annular, spaced-apart stiffeningribs 22 which protrude from anouter surface 24. - In another embodiment, the
upright stand 20 is generally cone shaped as shown inFIG. 2 . In this embodiment, thestand 20 comprises three contiguous sections including abase section 25, acenter section 26 joined to thebase section 25 at an inwardly directedannular step 27, and anupper section 28 joined to thecenter section 26 at an outwardly directedannular step 29. The fact that the bottom ofupper section 28 is of a greater diameter than the upper end of thecenter section 26, assures that thedelimiters 10 do not tend to stick together when stacked or nested. - In
FIG. 3 it is seen that thedelimiters 10 may be joined by a flexibleelongate member 60 such as a crowd-control tape, by a simple loop engagement about the tie-onterminal 50 of each of the units thus forming a combination for establishing a boundary about a crime scene or a hazard. Aweighting ring 70 may be placed over the delimiters to assure upright standing stability, as is shown inFIGS. 1 and 3 . - The tie-on terminal 50 may be in the form of a mushroom, as shown in
FIGS. 1-3 , or may be molded as ashaft 52 extending upwardly into theaperture 42 withsmall pimples 54 arranged so that a tape tied to the shaft is not likely to be dislodged from the shaft by sliding upwardly. The shaft preferably provides abolt hole 56 therein. - While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims.
