The invention relates to shark repelling apparel.
Shark attacks are a problem for surfers, divers, kite surfers, triathletes, water skiers, recreational ocean swimmers, sailors, persons lost at sea and those engaged in aquatic activities generally.
Numerous techniques have been attempted and suggested to protect those engaged in such activities from attack by sharks. Exemplary include chemical repellants, fixed barriers such as cages, electromagnetic repellants, and wearable metal barriers.
U.S. Pat. Nos. 5,616,333 and 4,602,384 are directed to and contain a discussion of chemical repellants. United States Patent Application Publication No. US2003/0233694 is directed to and contains a discussion of electromagnetic repellants. U.S. Pat. No. 4,833,729 is directed to a wearable metal barrier composed of metal spikes integrated into a rubber or rubber-like suit.
U.S. Pat. No. 4,494,245 discloses a wetsuit for repelling predatory marine animals that uses aposematic, or protective, coloration. As disclosed in that patent, aposematic coloration is a defense mechanism that certain organisms, animals and plants alike, use to ward off predators. These organisms have bright colors that make them readily identifiable by the predator. They are also are very dangerous to the predator, for example they can be poisonous, so the predator readily learns to avoid them. Other organisms that are not dangerous to the predator also employ similar protective coloration, and this survival strategy is called mimicry. The '245 patent teaches the employment of this mimicry strategy in a method of repelling predatory animals by wearing a wetsuit having a coloration pattern that mimics that of the aposematic animal or its mimic, such as the sea snake Pelamis platurus, or the coral snake, which are known to elicit an avoidance responses in sharks. Taken as a whole, the '245 patent teaches that coloration is a key factor and that two or more colors should be employed, preferably chosen from yellow, black and red, in a pattern that reproduces the pattern of an organism known to be aposematic, or a mimic of an aposematic, for that predator.
The invention is based on the surprising discovery that it is the pattern, rather than the color alone or the combination of color and pattern, that is the critical element in repelling sharks. Specifically, it has been determined that a striped pattern is necessary and most effective in repelling sharks.
Accordingly, in one embodiment, the invention provides water apparel, for example, a wetsuit, having a striped pattern on its exterior surface. The striped pattern should be completely visible to a human eye having 20/20 vision from a distance of at least one yard. The striped pattern can be made by applying a plurality of bands of a contrasting color to the exterior of a solidly colored wetsuit or the wetsuit can be made such that the plurality of bands are an integral part of the wetsuit. The bands may be straight or may form a wavy, drawn-out pattern similar to tiger or zebra stripping. In the latter case, the bands should preferably form arc-like, flowing curves.
With regard to the upright axis of the wetsuit, the bands can be arranged and disposed horizontally, vertically or diagonally. The horizontal, vertical or diagonal bands can be disposed in a substantially parallel arrangement to each other. The bands can be included in only a portion of the wetsuit or be included in or on the entire wetsuit. Further, the bands can be uniform or can vary in width and length. Additionally, a combination of bands, for example, vertical bands and diagonal bands, can be employed in or on the same suit of varying or of uniform widths, the vertical bands being disposed substantially parallel to each other and the diagonal bands being disposed substantially parallel to each other, but of course, not to the vertical bands.

It will be appreciated that the white bands and black background employed here are for illustration purposes only. The invention includes aquatic apparel having any combination of colors or hues, as long as the bands are composed of a color or hue that is divergent and distinct from the other colors or hues. For example, a suit of blue, green, violet or black may have a plurality of white, orange, red or yellow bands, or a combination of white, orange, red and yellow bands. A suit of white, orange, red or yellow may have a plurality of blue, green, violet or black, or a combination of blue, green, violet and black bands. A suit of lime green may have a plurality of violet, bright red, bright yellow or bright orange bands. What is important is that the colors selected be divergent and distinct from each other, such that the visual change from one color to another color is definitive and sudden or abrupt and the bands readily “stand-out” against a “background”. The striped pattern should be completely visible to a human eye having 20/20 vision from a distance of at least one yard. Accordingly, combinations of highly saturated, ruminant, colors or hues are preferred.
Many different color combinations may be employed and their selection will depend on their hue and intensity. The skilled artisan will be able to readily select appropriate combinations and hues and intensities meeting these characteristics. Thus, in addition to the white and black combination exemplified, various combinations of highly saturated, ruminant, colors may be employed to create the divergent and distinct stripped pattern.
It will also be appreciated that while the invention is described in terms of wetsuits, which are specialized aquatic garments typically composed of neoprene or other kinds of synthetic rubbers that have insulating characteristics, it may be employed for any kind of water apparel, for example boardshorts, rash and U.V. skins, whether full body, or tops and bottoms, swim tops, swim shorts and bathing suits. Likewise, while the invention is described in terms of hoods, it is equally applicable to gloves and boots.
Thus, although the invention has been described with respect to specific examples and embodiments, it is not intended that such specific references be considered limitations upon the scope of the invention, which is set forth in the following claims.
This application claims the benefit of priority from U.S. Provisional Application No. 60/627,893, filed Nov. 16, 2004, entitled STRIPED WETSUIT. The entirety of the contents of that application are incorporated by reference herein.
