Abstract
A portable roadway construction barrier comprising vertically telescoping sections which allow the barrier to be expanded for use or collapsed for storage and transport. The sections are held in the expanded position using locking devices formed at the junctions between the sections. The uppermost section may comprise a handle to facilitate transport and the collapse or expansion of the barrier. The base section may include a recess to allow efficient stacking of multiple barriers in the collapsed state.
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 60/942,683, filed Jun. 8, 2007, entitled COLLAPSIBLE STACKABLE HIGHWAY CONSTRUCTION BARRIER, which is hereby incorporated by reference in its entirety.
- The present invention generally relates to portable barrier devices and, more particularly, to a collapsible and stackable roadway construction barrier.
- The design and use of so-called traffic drums or traffic barrels is well-known in the art and comprise a familiar sight on the nation's roadways, particularly in construction areas where it is desired to control traffic access to particular areas. Such barriers, or channelizers as they are sometimes called, are generally formed of impact-resistant plastic and are typically configured as tiered drums having a base that is wider than the top of the drum in order to enhance stability. Additionally, the bottom of the barrier is typically weighted in order to keep the barrier in place once it has been placed by the construction or safety crew.
- A drawback to the prior art barrier design is that it is bulky and occupies a considerable amount of space when being stored and transported. This presents increased costs and logistical problems for both the storage of the barriers between uses, as well as the transport and installation of the barriers at the location where it is desired to control traffic. There is therefore a need for improvements in this area.
- Accordingly, a portable roadway construction barrier is disclosed, comprising a plurality of vertically telescoping hollow sections; and a hollow base section; wherein the horizontal perimeters of the vertically telescoping hollow sections comprise substantially the same geometric shape; and wherein the vertically telescoping hollow sections are horizontally sized to be collapsible into the hollow base section.

FIG. 4A is a perspective view of the barrier ofFIG. 1A shown in the expanded state. -
FIG. 4B is a perspective view of the barrier ofFIG. 1A shown in the collapsed state. - For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, and alterations and modifications in the illustrated device, and further applications of the principles of the invention as illustrated therein are herein contemplated as would normally occur to one skilled in the art to which the invention relates.
- A first embodiment collapsible and stackable roadway construction barrier is illustrated in
FIGS. 1A and 4A and indicated generally at 10.Barrier 10 is constructed ofseparate sections barrier 10. Although thebarrier 10 is illustrated as having five sections 12-20, the present disclosure comprehends barriers which have more or fewer sections. -
Top section 12 includes a closed lid portion, to which is affixed ahandle 22 having anopening 24 formed therein and functioning as a carry handle for thebarrier 10.Handle 22 is also used for expanding and collapsing thebarrier 10, as explained hereinbelow. In the first embodiment, the opening 24 is sized to be easily grasped by workers wearing gloves. Thehandle 22 includeslight mount holes 26 that allow lights to be mounted to thebarrier 10 for versatile lighting options. As shown inFIG. 3 , thehandle 22 additionally includesflag mount slots 27 that allow flags to be mounted to thebarrier 10 for versatile flagging options. - In the first embodiment, each section 12-20 of
barrier 10 is formed to have a generally circular cross-section, but other cross-sectional shapes are also comprehended in other embodiments. Thebase section 20 may include a thickened circumferentialouter rim 28 that increases both the diameter and the weight of thebase 20, thereby enhancing the stability of thebarrier 10 and tending to keep thebarrier 10 in an upright position despite wind loading and other forces that may be applied to thebarrier 10. Thebase section 20 also includes arecess 30 formed in the central section thereof, which allows room to receive thehandle 22 of anadjacent barrier 10 when stacked, as described in greater detail hereinbelow. - At each junction between adjacent sections 12-20, there are formed locking devices in the form of complementary circumferential protrusions and indentations which allow the sections to be releasably locked together, as shown in
FIG. 2 . As one non-limiting example, a portion of the intersection betweensections protrusion 32 formed circumferentially into theouter surface 33 ofsection 12 and acorresponding indentation 34 formed circumferentially on theinner surface 35 ofsection 14. Each of the sections 12-20 will have at least one such locking device between adjacent sections. Provision of multiple locking devices between adjacent sections is also comprehended by the present disclosure. In addition to a continuous protrusion and indentation around the circumference of the sections 12-20, the present disclosure contemplates that the locking device can be implemented as individual protrusions and indentations placed at various points around the circumference of the sections 12-20. Theprotrusions 32 andindentations 34 are sized so as to naturally nest with one another when brought into mutual alignment. AlthoughFIG. 2 shows theprotrusion 32 andindentation 34 as mutually nesting curvatures, the present disclosure contemplates that the other shapes may be used to implement the locking device. - With continuing reference to
FIGS. 1 and 2 , thebarrier 10 may be collapsed from its extended position by simply applying enough downward pressure on its top surface (typically by pressing on the handle 22) to force theprotrusions 32 to disengage from the associatedindentations 34. In the first embodiment, a force of approximately 4 to 6 lbs is required to accomplish this. Further downward pressure will cause the sections 12-20 to nest substantially completely as shown in theFIGS. 1B and 4B . Expansion of the collapsedbarrier 10 is accomplished by the reverse operation, namely applying a pulling force to thehandle 22 in the upward direction until theprotrusions 32 engage their associatedindentations 34, at which point the barrier sections 12-20 will lock in their expanded positions as shown inFIGS. 1A and 4A . - When in the collapsed state, the
barrier 10 occupies approximately one-fifth the volumetric space of the prior art barriers. Storage, handling and transport of thebarrier 10 are therefore greatly facilitated in relation to the prior art barriers. Furthermore, the collapsedbarrier 10 may be stacked on top of othersuch barriers 10, since thehandle 22 will nest inside therecess 30 of thebarrier 10 above. This further facilitates efficient storage, handling and transport of thebarrier 10. - The
barrier 10 may be formed from any suitable material and by any suitable manufacturing process. Thefirst embodiment barrier 10 is manufactured by the spinning of plastic fibers. High volumes of thebarriers 10 may be cost-effectively manufactured from molds using injection molding techniques as is known in the art. Thebarriers 10 can be made to any size, shape and design required by the relevant regulatory body, such as the U.S. Department of Transportation. Optionally, the surface ofbarrier 10 may have reflective bands formed therearound in order to make them more visible to vehicles at night. Such reflective bands may be formed using Scotchlite® (Retroreflective Sheeting (available from 3M®, St. Paul, Minn.). - While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
