BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the field of highway barriers. Particularly, it relates to center median barriers especially those made from prefabricated concrete. Such devices are commonly known as “Jersey barriers”.
A Jersey barrier (or sometimes called Jersey wall) is a modular divider used to separate lanes of traffic, either vehicles from one another, or vehicles from pedestrians and/or cyclists. The shape of such barriers was designed to minimize damage to a car, truck or other vehicle that makes incidental contact with it while preventing lane crossovers and avoiding head-on collisions. Jersey barriers are also used to reroute vehicular traffic and/or protect pedestrians during road construction. More recently, they have served as temporary or semi-permanent protection against land born attacks from suicide car bombers.
According to Wikipedia, the Jersey barrier was developed at the Stevens Institute of Technology in 1950's but introduced in its most current form in 1959. Per the auspices of the New Jersey State Highway Department, such barriers were meant to divide multiple lanes of a highway, particularly the flow of traffic in a first direction, from the opposite flow of traffic in the other (oncoming) direction. A typical Jersey barrier stands 32 inches (81 cm) tall and is made of steel-reinforced poured concrete. Some barriers are purposefully constructed with embedded steel protruding from each end. Those protrusions allow adjoining barriers to be linked to one another as part of a more permanent emplacement.
The widespread use of such barriers on roads has led to wider applications including: use as a generic, portable barrier during construction projects and/or for temporary traffic re-routing as part of a stopgap carpool or “rush hour” bridge/highway lane reversal.
The original Jersey barrier profile was intended to minimize vehicular damage through incidental contact. In “shallow” angle hits, car fender/sheet metal damage should be reduced as the vehicle's tires are meant to ride up the lower sloped faces of such barriers before falling back onto the lane/road surface. Such barriers should minimize the chances of a head-on crash by gradually lifting the vehicle that contacts same and pivoting it away from oncoming traffic in the opposite direction.
In 1968, the Ontario, Canada Department of Highways introduced a taller variation of barrier standing 42 inches (107 cm), or about 10 inches (25 cm) higher than the common U.S. barrier size. Thereafter, the New Jersey Turnpike Authority developed and tested a similar, more heavily reinforced design. It has been credited with effectively containing and redirecting larger vehicles, including semi-trailer (tractor-trailer) trucks. While the benefits of a taller highway barrier may be known, there has not been a cost-effective impermeable means for modifying existing (shorter) barriers to make them “safer” let alone in an aesthetically pleasing manner.
2. Relevant Art
One of the first known barrier improvements was patented by Camomilla et al. in U.S. Pat. No. 6,840,706. It included a double dampening effect that used ductile anchor components, including rigidly connected steel plates at the barrier base.
A different construction of barrier style was the subject of Ceccarelli U.S. Pat. No. 7,226,237. It employed a plurality of tubular modules extending upwardly from a ground connect.
Yet another set of interconnecting modular elements was the subject of Serafin U.S. Pat. No. 8,172,204.
There have also been proposals for making a continuous screen barrier using interconnecting panels. See, Borgnini U.S. Pat. No. 5,149,061. Continuous uprights on Jersey barrier was the focus of European Patent Application Serial No. 1,619,311. And in McNally et al., U.S. Published Application No. 20050135878, Jersey barriers were fitted with temporary, “bolt on” risers. Lastly, in White et al. U.S. Pat. No. 8,001,880, it was proposed to make more attack resistant (especially bulletproof) protectors using add-ons to Jersey style barrier frame.
SUMMARY OF THE INVENTION
A primary object of this invention is to provide an improved cap or add-on for raising the protectable height/protection range of an existing (i.e. previously installed) roadway Jersey barrier. It is critical that any such “adapter” be cost effective, quick to install, not labor intensive and yet have greater structural significance that known temporarily erected panels or those string of continuous vertical slats sometimes situated atop super highway/turnpike dividers for reducing opposing traffic headlight glare.
The heavy, permanent cap toppers of this invention are preferably made from concrete but with proper weighting could be made from fiberglass, composites, rubber and/or recycled plastic materials in the alternative. Regardless of material, they will surely provide the advantages of the integrally formed, higher barriers mentioned above, such as significant opposing headlight glare reduction. In addition, it is less likely that a whole vehicle or major parts of same (such as a tire, side mirror, etc.) will rise up and fully cross over these extra-high, purposefully raised center barriers for then crossing over and into unsuspecting traffic traveling the other way on the opposite side of such barriers. Upon impacting such barrier extensions, the cars and/or their major components will more likely stay on the same side of traffic flow where later following vehicles may have a greater chance of swerving to avoid impact.
These barrier add-on's are also structurally more sound/substantial than the flat panel and/or flimsy multi-slat barrier additions being used in some locations. The latter known varieties can also be more prone to “sailing” because of their vulnerability to high winds and greater possibility of individual slat separations from the top of existing highway barriers.
This invention also provides means for communities/municipalities to impart some degree of creative “flair” to the central barriers on those sections of highways/thruways extending through their respective communities. It enables the addition of particular raised cap configurations to their existing Jersey barriers, said cap additions having special patterns and/or colors or possibly distinctive reflector means added in spaced distances.
SUMMARY OF THE DRAWINGS
Further features, objectives and advantages of this invention will become clearer with the following detailed description made with reference to the accompanying drawings in which:
DESCRIPTION OF PREFERRED EMBODIMENTS
Jersey barriers have become an acceptable method for preventing traffic from penetrating the barrier and crossing the highway median into oncoming traffic where such barriers are installed. Each individual barrier has a widened base, sides with two sloping sections, and a flattened top surface. Usually made from concrete, the Jersey barrier is heavy and durable, yet possesses the proper shape and mass to deflect most small vehicles back into the lane from whence they came. They require little or no periodic maintenance. And even in today's shorter heights, standard barriers provide some security by deterring pedestrian traffic from wanting to straddle or otherwise cross over a whole series of such dividers.
Known Jersey barriers are relatively easy to move or install. Common barrier designs include two rectangular notches at the bottom (through the short axis). Those notches allow individual barriers to be raised by a forklift or pronged front-end loader. Barriers intended for short-term placement, especially in military and security uses, might include one or more steel rebar loops at or near their top surface for rapid hook-and-cable lifting.
Lately, there have been Jersey barrier additions designed to reduce, minimize or eliminate the blinding effects of opposing traffic headlights. One solution was to provide multiple slat-like extensions, each individually affixed, to the top surface of each Jersey barrier so that the lights of oncoming traffic are not readily visible. Such “blinders” actually allow opposing traffic to be seen in the distance AND when immediately adjacent the car opposite the barrier from the nearly 90 degree angle for each slat/blind. That has to be at or near perpendicular since it must block the headlight penetration from BOTH sides of the highway divider. A solid sheet might accomplish the same result, but it would be more difficult to attach, maintain AND render itself more vulnerable to damage as elongated plastic sheet separators would have a greater tendency to sail and dislodge in stronger wind gusts.
With the nominal physical divide from one or more plastic extensions, there is little to no additional protection afforded by a series of angled slats. Should a heavier vehicle, trailer, bus or the like plop over and onto such extensions in an accident, they will crack and/or crumble.
This invention seeks to modify the standard Jersey barrier by providing a quick and easy installation of a supplemental physical (permanently installed) vertical addition that will increase the difficulty (i.e. eliminate the likelihood) of pedestrians scaling, straddling and/or climbing over same. The invention also affords protection against the intimidating headlights of opposing traffic . . . regardless of angling. And a raised barrier via the extension varieties depicted herein will keep break off components, if not whole vehicles, from crossing over and “surprising” traffic flowing past in the opposite direction. It does so with no fear of “sailing” or otherwise blowing away. These caps are sufficiently weighty to stay onto the underlying barrier bottoms over which they will be installed and/or permanently mounted.
In the first embodiment shown in
For the preferred mounting means of this first embodiment, there are a plurality of holes H extending from the top surface 18 and downwardly towards the top surface J18 of the existing barrier. These holes H may be pre-formed into the respective caps during initial manufacture, or drilled into and through the bodies of same, after the fact. Each hole H is intended to have a bolt B positioned therein and downwardly into top surface J18 for permanently affixing cap 10 to Jersey Barrier JB.

Ultimately, the present invention will enable certain customizations of barrier “art” so that all barrier tops for a given community may be fitted with common decorative (in color, texture and/or pattern) inserts or raised regions. See, for example, the multiple square sequencing of
Each barrier cap may be further provided with suitable interconnecting means for supplementing the connection(s) made between underlying, adjacent Jersey barrier bottoms. Like the directional headlight reflectors described above, these interconnects are not shown/seen in any of the accompanying drawings, however.
