## Background
FIELD OF THE INVENTION
This invention relates to the field of Vessel Thru-Hull Fittings and, more particularly, to a window housing for use with a conventional transducer style thru-hull vessel fitting to permit receipt of an underwater lighting device or camera device.
BACKGROUND OF THE INVENTION
The use of thru-hull is well known. A conventional thru-hull vessel fitting provides an aperture through a side wall of a vessel hull. Current boating techniques require numerous thru-hull fittings above and below the water line. Fitting above the water line include cockpit draining, gray water drains for faucet and showers, anchor closet drains, AC cooling water drains, fish box drains, bilge pump drains and so forth. Thru-hull fittings below the water line are use for main engine cooling intakes, generator engine cooling intakes, air conditioning intakes, head water intakes, fish live well intakes, raw water wash-down intakes, and so forth. Further, conventional thru-hull fitting are used to support electronic devices such a depth and speed transducers.
A conventional transducer thru-hull fitting consists of an externally threaded pipe having a generally smooth inner surface. One end of the threaded pipe includes a flange fitting for securement to the vessel hull, or includes an tapered end if a flush attachment is desired. The flanges are bonded to the vessel by use of an adhesive/sealer, such as 3M 5200, wherein the threaded pipe is permanently mounted at an angle substantially perpendicular to the outer surface of the vessel hull. The inner surface of the pipe provides an open aperture allowing the ingress of water. An electric transducer is place within the aperture providing an uninterrupted access to the water.
The instant inventor employed the use of conventional transducer style thru-hulls fittings for securement of underwater cameras such as that disclosed in U.S. Pat. Nos. 6,100,921 and 6,115,060 the contents of which are incorporated herein by reference.
The use of underwater light is also well known. Underwater lighting is commonly used to attach fish but has also provided entertainment for those that frequent the water, especially pleasure boaters. It is now very common to find lights attached to the hull of a boat for use in illuminating the water while a boat is docked in a marina. The illumination of the water enhancing the safety around the boat, as well as providing entertainment as the lights attach a wide variety of fish.
Current underwater lighting devices employ that are secured to a vessel hull are extremely expensive, primarily due to the speciality thru-hull fitting that is employed. The speciality thru-hull fitting must prevent water entry yet provide an unobstructed window for passage of light from a halogen lamp, Light Emitting Diode (LED) or any other type of lighting element employed.
U.S. Pat. No. 7,044,623 discloses an underwater light requiring a specialty thru-hull vessel fitting. The fitting includes a flange placed on the outside of the vessel hull and an inner flange having a jacking plate. A jacking ring is used to squeeze the hull between the flanges. A window panel is permanently with the outer flange. If the window panel is scratched, breached, or damaged in any manner, replacement of the entire thru-hull is required.
A problem current with underwater lights is not only the cost of manufacturing the speciality housing, but the cost for repairing a speciality thru-hull fitting should any damage occur to the window panel. The window panel on current underwater lights is exposed to the elements at all times. Growth can cover the window requiring a diver to enter the water for cleaning. Entering the water at night, when it is cold, or when the conditions are less than ideal is typically avoided which leads to poor lighting situations.
Even if a diver is used to clean an underwater light having a permanently mounted window, improper handling can quickly damage the current window panels. Divers commonly use paint scrapers to remove barnacles, and sanding pads to reactivate vessel bottoms painted with an ablative paint. Should the diver be careless, the current underwater light housing will be damaged and the boat removed from the water for repair of the damaged window panel. The time and expense associated with lifting a large vessel out the water can add thousands of dollars to the cost of replacement.
Thus, what is needed in the industry is an inexpensive window housing that accepts lighting elements or cameras, and provides a means for servicing of the window housing without removing the vessel from the water.
SUMMARY OF THE INVENTION
The instant invention is a window housing for use with a conventional transducer style thru-hull fitting. The window housing is receptive to an underwater lighting assembly or camera assembly. The window housing is tubular shaped having an outer surface that fits within the conventional transducer thru-hull fitting. The outer surface includes at least one gasket to seal the housing with a transparent window panel along a first end of the housing an a flange located along the length of the housing positioned so as to cause placement of the window panel flush with the outer surface of the vessel hole. Alternatively, the window panel may be dome shaped allowing dispersal of light when a light device is used, or better collection of images when a camera is employed. A first securement cap is used for placing the window housing in a fixed position in relation to the thru-hull fitting.
A light assembly consists of a tubular shaped item having an illumination source such as LED's located along the first end. Alternatively, the illumination source may be a Halogen light, strobe, fiber optic or high intensity discharge (HID) lights. In a preferred embodiment, the LED's are mounted on a support board with the contact inserted through holes. The LED's are wired together and then potted. The LED's are optimally packaged within a cluster to obtain the maximum illumination. The first end of the tubular shaped item is placed into the inner chamber of the window housing wherein the LED's are positioned adjacent to the window pane. Similar to the window housing, a second securement cap is used to securely secure the light assembly inside the window housing. Electrical connections for the LED's extend through the second end of the light assembly and can be connected to the appropriate power source whether it be AC or DC.
It should be noted that the use of a potted LED cluster or lamp prevents water entrance into the vessel even if a catastrophic failure of the window panel occurs.
The light assembly of the instant invention can be inserted or removed from while the vessel is in the water. The light may be pulled for service, color change, or the thru-hull may be used for other uses such as the cameras described in U.S. Pat. No. 6,100,921 or 6,115,060. Further, the use of a domed window panel permits use of a camera that extends beyond the outer side surface of the vessel. The extension permits the use of a directional camera within a sealed environment which eliminated water from contacting the lenses of the camera. The camera may be removed without water ingress, and replaced with a different style or focus camera, a light assembly, or a plug.
In addition, the window housing can be removed even while the through hull is subjected to water pressure. While the pulling of the window housing permits water to pass through the hull, the flow of water can be quickly stopped by replacing the window housing with cap, plug, or transducer while the window housing is being serviced.
Thus an objective of the instant invention is to provide a low cost window housing that can be used with a conventional transducer style thru-hull fitting.
Still another objective of the invention is to provide a low cost window housing receptive to a lighting or camera assembly, or a combination light/camera.
Still another objective of the invention is to provide a window housing that can be removed from inside the vessel for cleaning, replacement, or substitution with other thru-hull mounted devices without special tools or the need to lift the boat out of the water.
Still another objective of the invention is to provide a window housing having a window panel that is flush with an outer surface of a vessel hull, or can be domed allowing for greater dispersal of light or camera angling.
Still another objective of the instant invention is to provide a safety factor that if the window panel should leak the use of a potted light assembly or camera assembly will prevent water from entering the vessel.
Another objective of the invention is to provide an underwater light that can be removed without tools or damaging of the hull.
Still another objective of the invention is to provide an underwater light that can be removed for servicing without tools or water entry in to the vessel, while the vessel is in the water.
Yet still another objective of the invention is to provide an underwater light that can be removed and replace with other lights to vary color, intensity, and temperature.
