A first embodiment of a traffic delineator in the present invention, as shown in FIGS. [0041] 1-10, includes a cylinder 1 and a base combined together.
The [0042] cylinder 1 is hollow, blow molded, having an M-shaped grip 10 provided on a top portion with two parallel through holes 11 defined by a circumferential wall 12 as shown in FIGS. 4 and 5. Then cordon ropes 3 may be connected with the two parallel through holes 11 by means of ring hooks 30 quickly and conveniently hooking in the holes 11 for cordoning an investigating area to prohibit common people from entering there. Further a small through hole 13 is bored a little on the two holes 11 for affixing and removing a warning lamp 4 therein easily as shown in FIG. 9 to give a warning during the night. In addition, two not-through grooves 14 are formed in the top portion, forming a θ angle with the small through hole 13 (preferably 45 degrees) for inserting warning flags 5 therein as another warning method.
The [0043] cylinder 1 further has three flanges 15 spaced apart equidistantly in an upper portion defining two areas 150 adhered with reflexive sheets 6, which may not friction with the ground even if the cylinder 1 falls down, protected by the three flanges 15. Further, the cylinder has grip holes 18 formed abutting each other in its circumferential wall in a lower portion, connected with three ribs 180 the circumferential wall. Then four fingers of a person can insert in the grip holes 18 to carry the traffic delineator, with the ribs 180 reinforcing the cylinder 1.
Next, the [0044] cylinder 1 has a lower end portion 16 of a little larger diameter than the rest portion, conforming to the inner diameter of a center hole 20 of the base 2 to let the lower end portion fitting in the center hole 20 and standing stably on the ground by lowering the center of gravity of the cylinder 1. In blow molding process of a cylinder 1, an annular bottom 17 is formed in the bottom end portion, having a thickness (D) larger than that (d) of the cylinder wall, preferably two times more, permitting the annular bottom 17 stand on the ground stably.
Next, the [0045] base 2 may be made hexagonal or of other shapes, having the center hole 20 for the lower end portion of the cylinder 1 to fit therein, keeping the cylinder 1 stand on the ground very stable.
FIGS. 11 and 12 show a second embodiment of a traffic delineator, which has almost the same structure modifying the first embodiment, only different in a disc-[0046] shaped bottom 17A of the lower end portion of the cylinder 1 instead of the annular bottom 17 in the first embodiment, preventing the cylinder 1 from falling off the base 2 or the traffic delineator from falling down.
A third embodiment of a traffic delineator shown in FIG. 13 has the same structure, except no grip holes [0047] 18 provided in the cylinder 1.
A fourth embodiment of a traffic delineator shown in FIGS. [0048] 14-19 has the same base as the first and the third embodiment, and the same cylinder as the first embodiment, having only a difference being one or two bellows members 70 additionally provided in an intermediate portion of the cylinder 7, formed integral with the cylinder during the blow molding process of the cylinder 7, having a waved or a corrugated wall as shown in FIGS. 15 and 16 to have a proper elasticity to adjust the whole height of the cylinder 1 for some degrees as shown in FIG. 16 (shrunk) or FIG. 13 (lengthened). In transporting or storing the traffic delineators, they can be shrunk to the shortest height, and in using they can be adjusted freely to any height between the highest and the shortest to suit to various kinds of roads. For example, it can be adjusted to the highest in using on an express way or a highway so as to permit drivers see them from afar, and it can be adjusted to the shortest in using on common roads in cities or speed limited roads. In addition, the bellows member 70 can be bent to show driving direction as shown in FIG. 17, and usable in the ways shown in FIGS. 8 and 9 of the first embodiment and in the ways shown in FIGS. 17 and 18.
Next, FIGS. [0049] 20-24 show a fifth embodiment of a traffic delineator having the same structure of the fifth and the first embodiment except the cylinder 1 shaped conical instead of straight hollow, usable for various places and demands.
Further, a sixth embodiment of a traffic delineator is shown in FIGS. [0050] 25-28, gotten by modifying the third embodiment and having a conical cylinder as the fifth embodiment, and a bellows member 70 as in the fourth embodiment.
A last seventh embodiment of a traffic delineator shown in FIGS. [0051] 29-31 has a larger diameter than the other embodiments, the same M-shaped grip 10 as the first to the fifth embodiments, an annular outwardly protruding flange 17 formed in a lower end of the hollow conical cylinder, an inner annular groove 170 defined by the annular flange 17, and a base 8 having an annular hollow wall 80 and an annular outwardly protruding flange 800 formed to extend out of the annular hollow wall 80 to engage the inner annular groove 170 smoothly. Further, the annular protruding flange 800 is divided into a plurality of small protruding edges separated by gaps 801 between every two abutting edges. As the base is made of plastic having proper elasticity and provision of the gaps 801 also produce some elasticity for the annular protruding flange 80 very smoothly engage the inner groove 170 to keep the upright cylinder 1 stand stably, and a bottom surface 81 of the base 8 has a concave surface to stand on the ground stably.
While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention. [0052]
