Description

FIELD OF THE INVENTION

The present invention relates to lighting equipment in general and, in particular, to illuminated headwear for use in nautical applications and watersports.

BACKGROUND OF THE INVENTION

Water safety for boaters including kayakers on the ocean or navigating a crowded port includes the use of proper lighting for avoiding collisions. Proper lighting can be as crucial as a paddle or hull when it comes to water safety for paddlers or boaters under oar power. Because of this, the United States Coast Guard has set lighting requirements that recreational boaters, including kayakers, must follow when on the water after dark or in periods of reduced visibility. The rules for boaters under sail may be similar to the rules for boaters using oar power, and the use of as much safety equipment as practical is wise, even when not legally required.

Sailing vessels may be required to carry and shine lamps combined in one lantern carried at or near the top of the mast where it can best be seen. Smaller sailing vessels and vessels under oars may exhibit the lights described, but if not, shall have ready at hand an electric torch or lighted lantern showing a white light which shall be exhibited in sufficient time to prevent collision.

Safety lighting used by non-boaters includes, for example, illuminated headwear for bicyclists. In general, the light source is mounted on the front of a helmet to assist the rider. U.S. Patent Application Publication No. 2010/0128468 discloses an illuminator device that attaches to a safety helmet for providing illumination when a user is moving.

Further illustrated in FIG. 1 is a third lens 44 disposed on the right side 16 of headwear 10. The third lens 44 may be configured to cast light of a second color to the right side of the headwear 10. According to nautical tradition, light cast to the right side of a moving vessel is green; however, other colors besides green are contemplated, therefore the third lens 44 may be configured to allow the lamp 30 to cast any desired color therethrough.

Moving on to FIG. 2, a second embodiment of the article of illuminated headwear 100 according to the invention also includes a top portion 12, a left side 14, and a right side 16. According to this second embodiment, the article of headwear 100 may also include a controllable power source 20 as discussed above. The second embodiment, however, may include one or more of a first lamp 60 disposed on the top portion 12 of the article of headwear 100, one or more of a second lamp 62 disposed on the left side 14 of the headwear 100, and one or more of a third lamp 64 disposed on the right side of the headwear 100.

According to the second embodiment, the first lamp(s) 60 are in electrical communication with power source 20 and may be configured to cast white light in up to and including a 360-degree pattern around the headwear 100. According to some embodiments, the first lamp(s) 60 may be configured to cast light in a pattern of less than 360 degrees around the headwear 100. For example, a shield or a plurality of shields may be used to prevent light from emanating in 360 degrees around the headwear 100.

Also, according to the second embodiment, the second lamp(s) 62 are disposed on the left side 14 of the headwear 100 in electrical communication with the power source 20 (illustrated in FIG. 1), and the second lamp(s) 62 may be configured to cast light through a first colored lens to the left of the headwear 100. Alternatively, the second lamp(s) 62 may include a colored LED or a plurality of colored LEDs, which may require no additional lens to cast colored light. That is, the second lamp(s) 62 may include any configuration of light sources configured to cast light of a second color. According to nautical tradition, the light cast to the left side of a moving vessel is red; however, it is contemplated that the light cast by the second lamp(s) 62 may be of any desired color(s).

The third lamp(s) 64 are disposed on the right side 16 of the headwear 100. The third lamp(s) 64 are in electrical communication with the power source 20, and the third lamp(s) 64 may be configured to cast light through a second colored lens to the right side of the headwear 100. Alternatively, the third lamp(s) 64 may include a colored LED or a plurality of colored LEDs, which require no additional lens to cast colored light. That is, the third lamp(s) 64 may include any configuration of light sources configured to cast light of a third color. According to nautical tradition, the light cast to the right side of a moving vessel is green; however, it is contemplated that the light cast by the third lamp(s) 64 may be of any desired color(s), including the same color as that cast by the second lamp(s) 62 or any different color. Further, lamps 60, 62, and 64 may be configured or programmed each to cast differently colored light. Such a configuration may be done using an appropriate processor 24 and colored lights, such as LEDs.

It should be noted that the power source 20 may be configured to power the first lamp(s) 60, the second lamp(s) 62, and third lamp(s) 64 individually. That is, a given first lamp 60 may be powered, while any of the second and third lamps 62, 64 may remain unlit. That is, any combination of lit and unlit lamps 60, 62, 64 is within the scope of the invention. Furthermore, it is contemplated that the lamps 60, 62, and 64 may be controlled to emit light in timed patterns, such as, for example, in an S.O.S. or other distress pattern.

The power source 20 may include a battery compartment which may be disposed in any location on, or inside of, the headwear 10; however, the location of the power source 20 may not be critical to the operation of the lamps 30, 60, 62, 64. A battery compartment may be disposed within lamp housing 11, or attached to headwear 10, or disposed within the brim of the headwear 10, for example. The battery(ies) may be electrically connected to the lamps 30, 60, 62, 64 and to a switch 21 of the power source 20 via wires or via other appropriate electrical connections (e.g., as generally shown via FIGS. 4A-4B). According to some embodiments, the battery compartment may be covered by brim material or other headwear material, as appropriate, to conceal the battery compartment from view.

FIG. 3 illustrates a plan view of a first lamp 30 that is configured to cast light either forward or rearward of the wearer of the headwear 10, or both. Such an alternate embodiment of the first lamp 30 may include a switch (e.g., switch 21) that is user controllable such that power to the front portion 30a only or the rear portion 30h only of the first lamp 30 may be individually selected. Further, the first lamp 30 may include one or two light shields that may be mechanically operated to shield a portion of the lens 40, such that, for non-limiting example, light is cast only to the front 180 degrees of the headwear 10 (e.g., as generally shown via FIG. 6).

The embodiments and configurations discussed above may be combined as appropriate. For example, while no single embodiment discussed included a single light source, or lamp with a single lens that may be configured to cast light in only a portion of the 360 degrees around the article of headwear 10, it is contemplated that a shield or other device may be used to cause white light to be cast in less than 360 degrees in embodiments using only a single lamp. Further, multiple shields may be used to cause light to be cast in a plurality of beams in any direction(s) around the headwear 10.

Further, it is contemplated that the headwear 10 may include a motion detector 22 that may communicate with a controller 26 to cause the colored lamps 30, 62, 64 to remain illuminated on the left and right sides of the vessel, regardless of head position of the user. That is, the red and green lamps may always be situated to port and starboard, respectively, relative to the direction of travel so when a kayak paddler, for instance, turns his head, the lights appropriately remain on the port and starboard sides, even though such lights are no longer on the right and the left sides of the head of the user. A motion detector 22 in communication with a signal mounted on the vessel, for example, at the bow, may detect which lamps must illuminate red or green such that the lamps illuminate toward the port and starboard of the vessel.

It should be emphasized that the above-described embodiments of the present disclosure, particularly, any “preferred” or “illustrative” embodiments, are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the disclosure. Many variations and modifications may be made to the above-described embodiment(s) of the disclosure without departing substantially from the spirit and principles of the disclosure.
