The present invention generally relates to protective covers for stanchions, and more particularly to a protective cover with an integrated lighting assembly for the purpose of providing illumination around the stanchion in darkness or other low visibility conditions.
Stanchions are primarily used as protective barriers for guarding stationary structures against damage that would result from being struck by a vehicle. They are commonly found in industrial facilities, parking garages and lots, and around drive thru lanes at restaurants. Generally, stanchions consist of an outer sleeve of elongated tubular steel and a concrete core. In construction, one end and a portion of the elongated tubular steel body is supported perpendicularly in a fixed surface while the opposite end extends above the fixed surface at a distance approximately equal to the embedded portion. The interior cavity of the elongated tubular steel member is commonly filled with concrete as a reinforcing complement. While stanchions can adequately protect stationary structures against damage from vehicle accidents, it is not uncommon for people to receive minor injuries, or their vehicles to receive minor damage, when contact is made with a stanchion.
Protective covers, as described in U.S. Pat. No. 5,323,583, aid in reducing injury to people, and damage to cars, that make contact with unprotected stanchions. The smooth surface of protective covers minimizes the scratching or cutting that occurs when a grazing contact is made with an unprotected stanchion that typically have a rough surface. Additionally, by covering a stanchion with a resilient protective cover, repetitive maintenance that stems from long-term exposure is minimized and its esthetic appearance is enhanced.
For various applications, protective covers are made in several different sizes and colors. Such covers may also be customized to display a customer logo or advertisement. The lightweight structure and design of such covers allows for quick and easy installation. Once fitted to a stanchion, the protective cover enhances its esthetic features while providing a durable and smooth surface that reduces repetitive maintenance and injury that may occur from minor accidents. Colored covers have good visibility, but in dimly light to dark conditions the cover's visibility is substantially decreased.
Lighting bollards, such as the one described in U.S. Pat. No. 4,438,484, are low-level ground mounted lighting structures primarily in use in urban environments for lighting pedestrian walkways and building entrances at night. Lighting bollards typically feature a base, a steel housing fashioned with one or more windows, and a source of illumination. The source of illumination, and its supporting electrical components, are generally mounted within the interior of the housing and receives its power from an external source. Other types of low-level outdoor lighting elements are used in residential landscaping applications to provide illumination around patios, walkways, or plant beds. These lighting elements commonly feature electrical conductors and a lamp receptacle disposed within an esthetic plastic housing. To provide power to these elements, they are generally connected to a track lighting type of network below the earth's surface.
While both these lighting structures are intended to provide illumination, neither is intended for use as a protective cover for a stanchion while providing light. A protective cover is useful for reducing repetitive maintenance and enhancing the esthetic character of stanchions, but a lighted protective cover would provide the additional feature of high visibility in a dark environment. Lighting bollards can provide the necessary light to maintain high visibility in poorly illuminated areas but they cannot provide the protective function of a stanchion.
The present invention is directed toward providing a lighted stanchion cover for a stanchion that includes an elongated tubular body with a lighting assembly disposed within its exterior surface. In the preferred embodiment, the lighted stanchion cover provides the stanchion with illumination without sacrificing the protective barrier function of the stanchion.
A preferred embodiment of the lighted stanchion cover, according to the invention, includes an elongated tubular body with opposite ends, one end open and the other closed. The interior cavity of the cover is dimensioned to receive the entire stanchion through its open end in slip fit engagement. A lighting assembly, that includes a light and power source, is integrated within the body of the cover and is fashioned so not to interfere with reception of the stanchion into the cover.
In the preferred embodiment, the lighting assembly is designed to receive power from an external power source. A second embodiment has the lighting assembly designed to receive power from an internal power source.
Optionally, to improve power efficiency, an electronic circuit can be integrated into the lighting assembly for power management and control to ensure that electrical energy will only be expended under certain conditions as a method of energy conservation.
Preferably, a lighted cover will be fastened to the fixed surface by use of a conventional fastening means sufficient for such purpose.
a is an enlarged view of an integrated light source according to the invention;
a are side elevational views of the lighted cover using photovoltaic devices as the power source; and
The lighted stanchion cover for a stanchion according to the invention is generally shown in the figures and indicated by reference number 10. With reference to
In construction, the stanchion extends outwardly from a fixed surface 16 and has a cap 18 and a base 20. Accordingly, the elongated tubular body 22 of the lighted cover 10 extends linearly between an open end 24 and a closed end 26. With reference to
In the preferred embodiment, the power source 32 would require minimal maintenance such as an external power source 32′ (refer to
The lighted cover may use other light sources such as halogen, incandescent, or florescent lamps 14′ that can be disposed in a lamp receptacle 42 within the interior cavity 24 of the elongated tubular body 22.
The lighting assembly 30 may include an electronic circuit 34 used for power management and control. Preferably, the electronic circuit 34 would include light and/or vibration sensing elements to trigger illumination only under dark conditions and when a vehicle is in close proximity to the stanchion.
In the preferred embodiment, the power source 32′, is near the base 20 of the stanchion 12, and is in communication with the electronic circuit 34 of the lighting assembly 30 that is positioned above the cap 18 of the stanchion and within the closed end 26 of the elongated tubular body 22. Further, the electronic circuit 34 is in communication with the light emitting diodes 14 positioned within the thickness 48 of the elongated tubular body 22.
Another embodiment, referring to
Alternatively, as shown in
The elongated tubular body 22 of the lighted cover 10 may be formed of a number of suitable, malleable structural materials, and is preferably formed of a structural plastic, including, for example, generally available low density polyethylenes and LEXAN™ brand polycarbonate. Also as known in the molding of plastics, various coloring agents may be mixed into the material of which the elongated tubular body 22 is formed to provide a durable coloring throughout. Further, a variety of material enhancing additives may be used, including, but not limited to, additives to resist ultraviolet deterioration.
The above and other features and uses of the invention will be recognized by those skilled in the art, from the specification, the claims that follow, and the attached drawings.
