Abstract: A pallet includes plural pallet bases and a pallet plate. The pallet base is formed integrally to shape as a cylinder having a connecting member at one end. The connecting member is provided with an annular portion planted symmetrical or dissymmetrical or evenly or unevenly with plural projections on the two sides respectively. An engaging member has to be set at the other end of the pallet base if the pallet plate is to be made double-layered, otherwise does not. The pallet plate able to be one-layer or double-layer is formed integrally together with the pallet bases so as to enhance the strength of the structure.

Abstract: An indicating tablet for a traffic cone includes a main body formed with a recessed surface for receiving a pattern or letters. The main body has its lower end formed integral with an insert member, and between the main body and the insert member is formed a connecting edge to enable the insert member to be moved elastically for facilitating the insert member to be inserted in the upper opening of a traffic cone. A plurality of clamping members are fixed at proper locations of the main body for clamping a pattern or letters on the indicating tablet for producing another indicating effect.

Abstract: A specific connecting rod for traffic cones includes an outer rod and an inner rod positioned in the outer rod to telescope therein. The outer ends of the outer rod and of the inner rod are respectively fixed with a socket with a ring fitting around a traffic cone so that the connecting rod can be connected between two traffic cones. The outer rod and the inner rod further respectively have a stop ring fixed on their inner end to keep the inner rod from falling out of the outer rod in telescoping to adjust the whole length of the connecting rod. The light reflective material on the outer surface of the outer rod and the inner rod is never scarred by telescoping movement of the inner rod or by placing the connecting rod on the ground, keeping intact the light reflecting function of he connecting rod.

Abstract: A traffic cone includes a cone-shaped body and a base. The cone-shaped body has a hole in the top and a connecting circumference formed in a lower end. The connecting circumference is provided with a large number of upright bars spaced apart equidistantly, and a through hole formed between every two neighboring bars. The base is formed in a mold that an already formed cone-shaped body is placed in advance before the base is formed so the base may be combined integral with the cone-shaped body after the base is finished. Then the base completely wraps around and hides the connecting circumference of the cone-shape body, with the through holes of the connecting circumference filled up totally by the base.

Abstract: A traffic cone includes a frustum-conical body and a base. The frustum-conical body has a hole in an upper end surface for a signal lamp, and a partial portion of its circumferential wall is thicker than another portion to form a gap between every two traffic cones stacked-up for easily taken off. The frustum-conical body has its bottom formed with a flange consisting of an upper and a lower annular wall and short ribs formed between the upper and the lower annular wall. The upper and the lower annular wall respectively have connect holes facing one another. The upper annular wall has an auxiliary material filling holes beside every connect hole and the lower annular wall has projecting arms. The base has a center hole to fit around the flange of the frustum-conical body to be combined with the same body as integral.

Abstract: A retro-reflective pavement marker includes a body, a base and a plurality of retro-reflective members. The body has two recesses in two opposite sides for the retro-reflective members to fit therein from inside. Stuffing material is filled in a gap between the body and the base after the both are combined together, combining the body, the base and the retro-reflective members together to make up the retro-reflective pavement marker. The retro-reflective pavement marker is kept very stable on a road after a foot or feet of the base are implanted in the ground of a road.

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.
