BACKGROUND OF THE INVENTION(a) Field of the Invention
This invention relates to boats, specifically a new item of manufacture secured to the existing rail and/or stanchion system of the bow of the boat primarily functioning as a heat sink and deflective shield achieved by maintaining an air space between the tautly stretched material and the bow surface of the boat. The ideal application is to have full clearance of the shade plane when fastened to the rail. User preference of the product and/or the design of the boat may warrant a need for spacers to prevent the plane of the shade cover from contacting the bow surface allowing heat to be conducted to the boat surface through to the cabin below. The spacers may be secured to the boat bow shade cover or the boat. Using a material engineered to withstand the extreme weather elements is ideal for obvious reasons, but a mesh allows rain to permeate the shade instead of pooling on the plane as it does with canvas or non porous materials. Non porous textiles also, are an effective heat shield, sun deflector, and gel coat protector. The slope of the railing may provide an adequate incline for water to pour off the shade cover plane.
(b) Description of the Related Art
Heat management is the premise of this invention and others similar in concept and use. Exterior solar screens reflect, absorb, and dissipate the sun's heat and glare before it passes through the window. Similar in appearance to insect screens, the sun blocking screens consist of a frame sized to a window to which the mesh textile is stretched and secured with spline. The solar screen frame is held in place by screwing clips into the window frame. The technology of commercially available materials vary in composition and the manufacturing process. Phifer and Textilene are the main solar screen materials preferred in the United States. The proven effectiveness of the solar screen textiles for solar shading/heat gain issues; daytime privacy without blocking the view and; UV protection of furnishings inspired other applications.
Shade sails shift the plane from vertical to horizontal comprised of a flexible mesh tensioned between several anchor points to shade playgrounds; picnic areas; patios and; places where people gather outside. Awn Tex., Commercial 95™, Polyfab USA LLC, manufacture knitted shade fabrics specifically for tension structures designed for residential and commercial applications.
The solar screen shade applications to vehicles are known in the prior art. For example, Simon U.S. Pat. No. 6,497,444 encases the rear section of a golf cart seating utilizes the existing structure of the vehicle to frame the shield; secures with straps and; shades the occupants from the sun's radiating heat, yet maintains visibility while driving.
Similarly, Tapia U.S. Pat. No. 6,725,807 applies the solar screen textile to the bed of a pick up truck to shade a pet. A retractable shade assembly comprising of the solar screen textile attached to a spring loaded rod is mounted to the vehicle. The loose end of the textile on the rod is drawn, extended along the bed of the truck and secured to a frame assembly. Tension is maintained on the pet canopy fabric by the resistance of the spring mechanism within the rod to which it is attached.
Car window roller blind systems use mesh materials to reduce glare, deflect the UV rays of the sun, and keep visibility through the shade.
Lastly, Forbis et al U.S. Pat. No. 7,322,154 frames the solar screen textile to shade structures and equipment from the radiant heat of the sun. Positioning the shade assembly slightly above or away from a structure or equipment yields an insulating airspace which enables effective shielding. Performing as a heat sink, the panels reduce the rate of solar heat gain to object being buffered.
A roundabout boat having seating in the open bow is known as a bow rider. A cover for the bow of a this type boat are usually for the purpose to protect the seating when not in use. A different bow cover on the market functions as a tarp to secure bulky recreational gear. A shade for a bow rider boat is for the purpose of shading the bow occupants when anchored or docked. Said shade is not intended for use when underway because the view is obstructed.
A cabin cruiser is a power driven pleasure boat with living accommodations inside the structure of the boat. The cabin temperature may become very warm on a sunny day making the room less comfortable to retreat for reprieve from the sun. If the boat is equipped with an air conditioner, the cabin may be cooled by running the appliance. If the boat does not have a generator and relies on shore power, the cabin temperature will elevate once the boat disconnects from the dock. If a boat does have a generator to run the air conditioner, fuel is consumed to operate the generator and, hours of use subtract from the life of the generator and air conditioner. A bow shade or cover for the utility of reflecting solar radiant heat and functioning as a heat sink preventing solar heat gain by conduction to the bow, then further to the cabin below is not available in the prior art to compare or improve.
BRIEF SUMMARY OF THE INVENTIONA shade cover attached to the bow rails and stanchions of a boat shields the bow from the sun and keeps the cabin below deck substantially cooler, thus a more comfortable temperature is maintained in the cabin for the enjoyment of the occupants. An ecologically-conscious benefit results with the use of the shade cover, because air conditioners would be used less to cool the cabin temperature, generators to run the air conditioners would be used less, fewer hours used on the generators to operate the air conditioner, and less fuel would be used to run the generators. The gel coat, which maintains the integrity of the fiberglass on the deck, would be protected from the sun by the shade cover. The properties of textiles engineered for tension membrane structures and solar screens are ideal for the boat bow shade cover application, because the open-weave or knitted mesh prevent water pooling; have excellent strength to weight ratios; favorable tensile strength; resistant to tearing; and are UV stabilized. Though solar screens were the inspiration for the invention, weather resistant, non-porous textiles function effectively as a heat sink, solar deflector, and gel coat protector.
The boat bow shade cover is attached to the existing railing and stanchion system on the bow of the boat. To effectively shade the bow, the shade cover material must not come in direct contact with the surface of the bow otherwise, heat would be conducted to the boat surface and to the cabin bellow. Considering the variances in boat designs, the size and shape of the shade is determined by the dimensions of the bow for which the shade cover is made. The key to keeping the shade off the boat is achieved by maintaining tension on the material connected to the existing rail/stanchion system and, if applicable, spacer(s) placed underneath to prevent direct contact of the shade cover to the bow surface. The configuration and plurality of said spacers is deemed by individual boat design and shade cover attachment position. The means in which to affix the shade and/or spacers may vary as well.
The attachment method of such an embodiment may include straps or cords sewn to the shade cover or pass through grommets or rings and may incorporate a quick release devise such as buckles, clamps, hooks, Velcro® to adjust the tension of the shade when securing to the railing/stanchion system. A shade cover may be tailor made to a specific bow to forgo adjustable features.
The air space between the shade cover and the bow surface is equally important as the shade cover itself. To support the effectiveness of the shade cover, the air space must be maintained. The rise of a bow or attachment position of the shade cover may compromise the space. The plane of the shade cover may be elevated with a spacer placed at the point where there may be contact. A spacer may be secured to the shade cover or the boat.
A modification to the shade cover for cabin cruisers having a walkthrough windshield to access the bow need a quick release seam from the aft edge of said shade forward to be able to approach the fastening system at the rails and stanchions as well as return to the helm.
