Traffic delineator

Abstract

A traffic delineator includes a hollow cylinder and a base, useable for connecting cordons, affixing a warning lamp, warning flags or indicating driving directions, etc. The cylinder has one or two areas separated by two or three outwardly extending flanges formed in an upper and an intermediate portion for adhering reflexive sheets on outer surfaces, an M-shaped grip with two parallel through holes, a small through hole on the two parallel holes and two grooves for inserting warning flags. The base has a center hole for the lower end portion of the cylinder to fit therein to stand upright stably by means of the large dimensions and the large weight of the base.

What is claimed is:  
     
         1 . A traffic delineator comprising a cylinder and a base, said cylinder having an M-shaped grip formed in a top portion and having two parallel through holes defined by a circumferential wall for a ring hook of a cordon rope to hook with, a small through hole formed a little on said two parallel through hole for affixing a warning lamp therein, two not-through grooves formed to make up a θ angle with said small through hole for inserting flags therein; said cylinder having three outwardly protruding flanges spaced apart in an upper portion and defining two areas adhered with reflexive sheets, said cylinder further having a lower end portion of a little larger diameter than the rest portion to conform to a center hole of said base, said lower end portion having an annular bottom with a larger thickness (D) than that (d) of a wall of said cylinder to permit said annular bottom rest on the ground stably.  
     
     
         2 . The traffic delineator as claimed in  claim 1 , wherein said cylinder has a bellows member formed in an upper portion and an intermediate portion integral, said bellow member having a waved or corrugated wall with some elasticity to lengthen and shrink, permitting said cylinder adjustable in its height between the highest and the shortest.  
     
     
         3 . The traffic delineator as claimed in  claim 1 , wherein said cylinder has a disc-shaped bottom instead of said annular bottom.  
     
     
         4 . A traffic delineator comprising a cylinder and a base, said cylinder having an M-shaped grip formed in a top portion, said M-shaped grip having two parallel through holes defined by a circumferential wall for a ring hook of a cordon rope to hook therein, a small through hole formed a little on said two parallel through holes for affixing a warning lamp therein, and two not-through grooves formed to make up a θ angle with said small through hole for inserting warning flags; said cylinder further having three outwardly protruding flanges properly spaced apart to define two areas adhered with reflexive sheets and a lower end portion with a larger diameter than the rest portion to conform to a center hole of said base, said lower end portion having a thickness (D) larger than that (d) of the wall of said cylinder to let an annular bottom of said lower end portion to rest on the ground stably; said cylinder further having plural grip holes formed to be supported with three ribs connected to a circumferential wall of said cylinder for easily carrying said traffic delineator and for separating rods to fit therein for forming a cordoned area.  
     
     
         5 . The traffic delineator as claimed in  claim 1 , wherein said bellows member of said cylinder has proper elasticity to let said cylinder bend to indicate a driving direction.  
     
     
         6 . A traffic delineator comprising a cylinder and a base, said cylinder having an M-shaped grip formed in a top portion, said M-shaped grip having two parallel through holes defined by a circumferential wall, said parallel through holes serving for hooking a ring hook of a cordon rope therein, a small through hole formed a little on said two parallel holes for affixing a warning lamp therein, two not-through grooves formed to make up a θ angle with said small through hole for inserting warning flags therein; said cylinder further having a lower end flange extending outwardly and an inner annular groove defined by said lower end flange, said base combined with said cylinder by fitting an annular projection formed to extend outward from an annular wall of said base with said inner annular groove, said annular projection divided into a plurality of small projecting edges separated by a gap between every two of said projecting edges, said gaps producing some elasticity for said annular projection to fit smoothly in said inner annular groove, and said base having a concave bottom surface to rest on the ground very stably.
