The present invention relates to traffic delineator devices. More particularly, the present invention is directed to a half barrel traffic barricade which is nestable/stackable for compact storage thereof.
Plastic traffic delineator devices are known and are common. They include, for example, lightweight plastic barrels which can be arranged on a roadway for directing and channeling traffic flows. The use of lightweight plastic for these devices, as opposed to wood or metal, has significantly increased driver and pedestrian safety by minimizing damage caused if a vehicle strikes the plastic barrel. However, wind and air movement caused by vehicles driving along the roadway can cause the lightweight plastic barrels to slide or tip over, thereby requiring frequent repositioning.
Accordingly, barrel delineators are typically made in two pieces: an upper barrel and a weighted base. The upper barrel is made of lightweight plastic and is adapted to releasably engage the base which can be made of a heavier, ballast material such as, for example, rubber or recycled automobile tires. There are many types of weighted bases used for plastic barrel barricades. For example, a traditional annular weighted base is shown and described in Nagler, U.S. Pat. No. 5,199,813. In use, the annular weighted base can be received over the barrel and engages a lower lip thereof for preventing the barrel from sliding or being blown or knocked over.
It is often necessary or desirable to transport or store the barrels between projects. In this regard, plastic barrels have traditionally been hollow having an open bottom end and a central cavity. Thus, the barrels can be nested/stacked for transportation or compact storage by inserting the top ends thereof through the open bottom end, and into the central cavity, of an adjacent barrel. Examples of traditional nestable/stackable plastic barrels are shown and described in Bent et al., U.S. Pat. No. 5,722,788; Bent et al., U.S. Pat. No. 6,019,542; Kulp et al., U.S. Pat. No. 5,026,204; Erwin et al., U.S. Pat. No. 4,973,190; Cowan, U.S. Pat. No. 5,234,280.
However, a disadvantage of traditional nestable/stackable plastic barrels is that they generally must be stored upright to prevent the stacked barrels from rolling or moving during transportation, and the nested/stacked plastic barrels commonly become stuck/wedged/jammed together and can require significant effort to separate. Traditional nestable/stackable plastic barrels are also costly to manufacture.
Accordingly, there exists a need for an improved lower cost traffic delineator device which can be nested/stacked together for transportation and/or compact storage thereof and which resists becoming stuck/wedge/jammed with adjacent nested/stacked delineator devices.
In the present invention, a half barrel traffic barricade for use with an annular traffic barricade base comprises a half tube-shaped vertical wall having a top end and a bottom end. A top panel is provided at and closes the top end of the vertical wall. The annular traffic barricade base is received over the vertical wall and engages the bottom end thereof for supporting the traffic barricade in a vertical position.
Preferably, the vertical wall is stepped and further comprises a convex front face, a concave rear face, and vertical wall edges.
Preferably, the half barrel traffic barricade further comprises stacking flanges provided along the vertical wall edges and a foot extension provided at the bottom end of the vertical wall. The annular traffic barricade base can engage the foot extension for supporting the traffic barricade in its vertical orientation.
Preferably, the convex front face and the concave rear face further comprise one or more reflective portions/surfaces. Yet more preferably, the convex front face and the concave rear face further comprise two or more reflective portions/surfaces which are arranged in an alternating, striped pattern.
Preferably, the half barrel traffic barricade further comprises a handle provided at the top end of the vertical wall, wherein the handle includes one or more mounting bores. Yet more preferably, one or more lights/reflectors are secured to the handle and engage the one or more mounting bores.
In another embodiment, the present invention is directed to a traffic delineator device for directing and channeling traffic comprising an annular traffic barricade base and a half barrel traffic barricade. The half barrel traffic barricade comprises a half tube-shaped vertical wall having a top end and a bottom end and a top panel provided at and closing the top end. The annular traffic barricade base is received over the vertical wall and engages the bottom end thereof for supporting the half barrel traffic barricade in a vertical position.
In yet another embodiment, the present invention is directed to a traffic directing/channeling system comprising a plurality of annular traffic barricade bases and a plurality of half barrel traffic barricades. Each half barrel traffic barricade comprises a half tube-shaped vertical wall having a top end and a bottom end and a top panel provided at and closing the top end. An annular traffic barricade base is received over each vertical wall and engages the bottom end thereof for supporting the half barrel traffic barricades in a vertical position.
Preferably, the vertical walls further comprise convex front faces, concave rear faces, and vertical wall edges, and a nesting/stacking pocket is defined between the concave rear faces and the adjacent top panels. Yet more preferably, the half barrel traffic barricades are nestable/stackable by inserting the front faces thereof into the nesting/stacking pocket of an adjacent half barrel traffic barricade.
Preferably, the half barrel traffic barricades further comprise stacking flanges extending along the vertical wall edges. Yet more preferably, the stacking flanges of adjacent nested/stacked half barrel traffic barricades are placed against/abutting one another for supporting the weight of the nested/stacked half barrel traffic barricades.
The above-mentioned and other features of this invention and the manner of attaining them will become more apparent, and the invention itself will be better understood by reference to the following description of the embodiments of the invention, taken in conjunction with the accompanying drawings, wherein:
Corresponding reference characters indicate corresponding parts throughout several views. Although the exemplification set out herein illustrates certain embodiments of the invention, the embodiments disclosed below are not intended to be exhaustive or to be construed as limiting the scope of the invention to the precise form disclosed.
A half barrel traffic barricade constructed in accordance with the principles of the present invention is shown and designated by the numeral 10. As shown in
As best seen in
Preferably, the traffic barricade 10 can include a foot extension 28 and a handle/mounting bracket 30 defined by and/or having a handle slot 32. The handle/mounting bracket 30 can be provided at the vertical wall 12 top end 16 and the foot extension 28 can be provided at the bottom end 18. The handle/mounting bracket 30 can be used for lifting and moving the traffic barricades 10 as necessary or desired.
In use, the traffic barricades 10 can be placed standing vertically with their bottom ends 18 resting on a road surface (not shown). A plurality of barricades 10 can be arranged as necessary or desired along the road for directing and channeling traffic. Preferably, the traffic barricades 10 are positioned with the front faces 20f thereof facing in the direction of on-coming traffic. Additionally, as shown in
The annular weighted bases 34 engage the foot extensions 28 for preventing the traffic barricades 10 from sliding or tipping over from light collisions, wind, and/or air movement caused by passing vehicles. The weighted bases 34 are, preferably, standard, commonly available annular traffic barrel bases adapted to provide ballast for traffic barrel barricades. Yet more preferably, the annular traffic barrel base 34 is made of rubber, recycled tires, or other suitable materials.
