The present invention relates to a flexible, durable light bar cover having an adjustable radius and a stiffening element that allows the cover to be more easily positioned on a light bar of a vehicle.
Light-emitting diode (LED) light bars a common after-market accessory for off-road and other sport utility vehicles, and emergency vehicles providing improved visibility in low-light conditions and programmable light arrays. LEDs are small, completely solid state, very power-efficient, long-lasting (as they have no filaments to burn out) and can be seen very easily even at great distances and in sunlight.
LED-based light bars can be made very thin, reducing wind resistance by around 8-10 percent. LED lights are also programmable with a wider variety of flash patterns because of their ability to be switched directly by electronic controllers, as opposed to discharging a capacitor through a gas-filled tube.
LED light bars are typically mounted across the roof or anterior to the roof of the vehicle to provide an overhead light without obstruction of the driver's view. Because light bars are mounted on vehicles, the face of the light bar is constantly exposed to dust, scratches and heat of the sun that can shorten the life of light bar. Thus, the useful life and appearance of a light bar can be aided by a protective cover. Many state laws require an opaque cover to be placed over such light bars as a safety precaution on the roads.
However, because of the length, position height, and position on the vehicle, it is difficult to apply a protective cover to the light bar. A person is required to reach up above the vehicle to access the light bar to try and place the cover on the light bar, and can only reach one side of the vehicle at a time. Thus, putting a light cover on a vehicle-mounted light bar is an awkward and challenging task, which may require the use of ladders and the assistance of another person.
Another problem is that light bars come in varied sizes and often without a light bar cover. Thus, light bar covers misfit many of the different light bar designs in the market.
Improved light bar covers are needed to overcome the drawbacks of conventional mechanical covers.
The present invention provides improved light bar cover for LED light bars. The presently disclosed light bar covers may cover the full circumference and length of a light bar and may include a multi-functional tool for easing the installation or removal. While installed, the light bar cover protects the light bar from various damages such as debris or the elements. The multi-function tool may be used to assist in the removal and installation of the cover when mounted in hard to access location. In various embodiments the multi-function tool may be used to deploy the cover, provide rigidity to the cover, and/or actuate a fastener for the cover.
The light bar cover may include a durable outer material for wrapping around the exterior of a conventional light bar such as a marine-grade, UV and water-resistant canvas material, to protect the light bar from the elements. In some embodiments, the material may be a nylon, polyester, neoprene, or other durable fabric that is sufficiently thick to substantially protect against UV penetration and may be chemically treated to be water-resistant. The light bar cover may have a perimeter shape that approximates the circumference and length of standard light bar sizes, with some ability to accommodate variations in such shapes. The light bar cover may have fasteners that allow it to be fastened around such light bars. In various embodiments, the fasteners may be zippers, hook and loop fasteners (Velcro), snaps, and/or other fastener mechanisms. In a preferred embodiment, the fasteners may be a zipper that runs along opposing lengths of the light bar cover.
A feature of the light bar cover that allows it to accommodate multiple light bar shapes is the cinchable lateral ends of the cover. In some embodiments, the light bar cover may include elastic hemming on the lateral ends of the cover. One or more elastic bands may be attached to the lateral ends of the cover to provide the functionality to cinch the lateral ends around support elements (e.g., bars) attached to the lateral ends of a light bar. In some embodiments, each lateral side of the light bar cover may include a hem that encloses a cinchable band that can be tightened around the support elements at the lateral ends of a light bar. For example, an elastic rope or bungee cord may be enclosed in a hemmed slot along each lateral end of the light bar cover with connectors at each end that allow the elastic rope or bungee cord to be tightened around the support elements at the lateral ends of a light bar.
The light bar cover of the present invention may also include an interior expansion mechanism for adjustment of the dimension of the light bar cover that corresponds to the circumference of the light bar (the “circumferential dimension”). This element may include elastic bands or lines, and/or a cinching flap that allows a portion of the circumferential dimension to be taken in to effectively reduce the dimension. In some embodiments, the expansion element may be an expansion flap of material on the inner side of the light bar cover that can be attached at different points along the circumferential dimension, allowing the material of the light bar cover to be taken in or let out. The attachment mechanism for attaching the expansion flap may be hook and loop fasteners (Velcro) that allow attachment at different points on the light bar cover and/or the expansion flap. Other fastening mechanisms may alternatively be used, such as snaps, button fasteners, zippers, etc. In some embodiments, the expansion flap may include elastic materials that aids in pulling in the material of the light bar for a tight fit.
In other embodiments, the expansion element may be elastic cords (e.g., interlacing cords) that are routed between two strips of grommets spaced apart from one another on the interior side of the light bar cover. The elastic cords bring in the circumferential dimension of the light bar cover yet are able to expand providing the length required to extend around the circumference of the light bar to be covered.
In other embodiments, the expansion element may be an elastic band that is expandable along the circumferential dimension of the light bar cover. The elastic band may be of various thicknesses. In some embodiments, the elastic band may run from one lateral side of the light bar cover to the other. The elastic band may bring in the circumferential dimension of the light bar cover yet are able to expand providing the length required to extend around the circumference of the light bar to be covered. In still further embodiments, the expansion element may include a plurality of the elastic bands expandable along the circumferential dimension. For example, the expansion element may include a plurality of elastic bands spaced evenly apart from one lateral side of the light bar cover to the other.
The light bar cover of the present invention may also include a multi-purpose rod that can be stored on the interior of the light bar cover between the expansion flap and the interior side of the light bar cover. The multipurpose rod may serve to provide rigidity to the light bar cover when it is inserted into the light bar cover, allowing one to extend the light bar cover across the length of the light bar when the light bar cover is being installed. This is an important advantage of the present invention, because it is difficult to reach across the entire vehicle (e.g., across the front of a vehicle for a light bar mounted over the windshield of the vehicle). The rigidity provided by the multi-purpose rod allows one to apply the light bar cover to a light bar easily from the ground.
The multi-purpose rod may also include a hook at one end thereof to allow one to remove the light bar cover from the ground. The hooked end of the multi-purpose rod may be used to reach across the car to undo the fasteners that join ends of the light bar cover at the edges of the circumferential dimension of the light bar cover. Specifically, the user may partially open the fasteners joining the ends of the light bar cover to access the multi-purpose rod. The hook of the multi-purpose rod may then be engaged with the fasteners (e.g., a zipper tab) and allow the user to undo the fasteners across the width of the vehicle while remaining on the ground. In some embodiments, the multi-purpose rod may be extendable (e.g., may have a telescoping design).
In some embodiments, the light bar cover may include a separate stiffening element for providing rigidity to the light bar cover from the multi-purpose rod. For example, the light bar cover may include a permanently attached stiffening rod or other structure to maintain the rigidity of the light bar cover. In such embodiments, the light bar cover may include additionally include a multipurpose rod for opening the light bar cover when it is installed and adding extra rigidity to the light bar cover. In still further embodiments, the light bar cover may include a different mechanism for opening the light bar cover, such as a rip cord that runs across the length of the light bar cover and can be pulled by a user from the ground to undue the fasteners binding the circumferential edges of the light bar cover.
The light bar cover of the present invention may additionally include an additional light bar lens pad on the interior side of the cover. The light bar lens pad may be a soft, scratch-preventing materials such as a microfiber, sheepskin, non-woven polypropylene fabric, polyvinyl acetate fabric, and other appropriately non-abrasive materials. The lens pad may have sufficient size and may be positioned on the light bar cover such that it can be reliably place over the light bar lens when the light bar cover is engaged over the light bar. For example, the lens pad should be located near one of the edges of the circumferential dimension such that the edges of the circumferential dimensions and the fasteners at the edges are located at the bottom of the light bar when the lens pad is located on the light bar lens. In this arrangement, the lens is protected and the position of the fasteners of the light bar cover are located inferiorly to allow for drainage of any moisture that may be captured in the light bar cover by gravity. The fasteners of the light bar cover should preferably be positioned on the interior surface of the light bar.
The light bar cover may additionally include one or more additional pockets for storing tools or other implements, such as flashlights, plyers, screwdrivers, multi-purpose tools, etc. Such pockets may be positioned on the exterior side of the light bar cover.
An example use case for the present invention is for installment on an above-window-mounted 52″ dual row light bar. However, the various embodiments disclosed herein are applicable to light bars of differing lengths, circumferences, mounting locations or elements. Other example use cases include application to a hood mounted light bar (in which case, the fastener elements may be moved to the top or rear of the light bar cover to allow for ease of operation).
