Abstract
A safety delineator is provided which includes a conical body portion to which is attached one or more vertical panels. The delineators may be stacked without removing the vertical panels, since each vertical panel is particularly designed to warp around the conical body portion to which it is attached as another vertical delineator slides over it.
Claims18
A stackable safety delineator, comprising:
- a body portion comprised of an outer wall, said outer wall including an inner wall surface which defines a hollow interior volume, said body portion having an open base end and a top end, and being wider at said base end than at said top end;
- and
- a projecting portion, disposed above said body portion, said projecting portion having a length of at least about five and one-half inches, which is sufficient to abut against the inner wall surface of a second one of said stackable safety delineators when said second stackable safety delineator is placed over said stackable safety delineator in a stacking relationship, to thereby limit the extent to which said stackable safety delineator is received within the hollow interior volume of said second stackable safety delineator in said stacking relationship, so that the stackable safety delineator cannot be disposed within the hollow interior volume of the second stackable safety delineator sufficiently far that the outer wall of the stackable safety delineator comes into interfering contact with the inner wall surface of the outer wall of the second stackable safety delineator.
A plurality of stackable safety delineators, comprising:
- a first delineator comprising a body portion, said body portion being comprised of an outer wall which includes an inner wall surface defining a hollow interior volume, said body portion having a base end and a top end, and being wider at said base end than at said top end, and a projecting portion, disposed above said body portion;
- a second delineator comprising a body portion, said body portion being comprised of an outer wall which includes an inner wall surface defining a hollow interior volume, said body portion having a base end and a top end, and being wider at said base end than at said top end, and a projecting portion having a length of at least about five and one-half inches, disposed above said body portion;
- wherein said first delineator is disposed in a stacking relationship over said second delineator, said length of the projecting portion of said second delineator being sufficient to abut against the inner wall surface of the body portion of the first delineator when said first delineator is placed over said second delineator, to thereby limit the extent to which said second delineator is received within the hollow interior volume of said first delineator in said stacking relationship, so that said second delineator is not disposed within the hollow interior volume of the first delineator sufficiently far that the outer wall of the second delineator comes into interfering contact with the inner wall surface of the outer wall of the first delineator.
