Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Applications Serial Number 61/600,441, filed February 17, 2012 , entitled "Buoyancy Vest".

FIELD OF THE INVENTION

The present invention relates, in general, to body surfing, and more particularly to a body surfing buoyancy vest. More particularly, the present invention relates to a buoyancy vest to be worn under a body surfing suit or wetsuit which is able to regulate the buoyancy of the surfer to enable them to maintain maximum control and buoyancy balance in the water.

BACKGROUND OF THE INVENTION

Body surfing is a way to enjoy the thrill of riding a wave in order to get the best ride the surfer must be buoyancy balanced. Body surfers, generally, simply extend their bodies horizontally, projecting their arms forward and in line with their body while allowing a breaking wave to drive them shoreward with the surf. To the body surfer, it is important to be able to ride waves of varied sizes, to enjoy a stable ride and to be able to control their bodies' direction and position and buoyancy on a wave face. Since a body surfer rarely uses any equipment other than swim fins, it is quite difficult for a body surfer to adequately control the stability of his ride and control his buoyancy.

The present invention seeks to overcome these limitations by providing the body surfer a means to stabilize his ride by controlling his/her buoyancy on the waves allowing his/her body to be in the proper position when the wave comes.

JP 2003 239116 relates to providing flexible clothing making movement of wearers easy and having adequate buoyancy. A separation type swimsuit as one example of clothing is composed of west and pants and several belt-like pockets in the vertical direction by the lining fabric are each formed in the both of these west and pants and several thin strip-like buoyancy sheets each made of low-density polyethylene are inserted in superposed state in each of these pockets. Since the swimsuit has buoyancy, the body floats with adequate buoyancy by only wearing the swimsuit. Since the swimsuit just fits the body and the buoyancy sheet is soft, the wearer is very movable and the swimsuit does not prevent swimming. As a result, physically-handicapped persons, aged persons and non-swimmers can receive underwater rehabilitation and swimming lessons without anxiety. Since the buoyancy can finely be adjusted by adjustment of the numbers of the buoyancy sheets, the swimsuit does not cause excessive floating and the swimsuit is appreciated also in children's swimming schools

SUMMARY

Accordingly, the present teachings provide a vest in accordance with claim 1. Advantageous features are defined in the dependent claims.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

After reading this description it will become apparent to one skilled in the art how to implement the invention in various alternative embodiments and alternative applications. However, all the various embodiments of the present invention will be described herein, it is understood that these embodiments are presented by way of an example only, and not limitation. As such, this detailed description of various alternative embodiments should not be construed to limit the scope or breadth of the present invention as set forth below.

With reference to Fig. 1, an embodiment of the buoyancy vest 100 is shown in a front view on a person. The buoyancy vest 100 is a vest worn on the user's upper torso to keep them more buoyant in the water. The buoyancy vest 100 includes a neck opening 102, a pair of arm holes 104, a front side 106 with an exterior surface and an interior surface, a back side 108 with an exterior surface and an interior surface (Fig. 2), pockets 110 and foam inserts 112 (Fig. 3) to be placed in the pockets 110. The buoyancy vest 100 is worn by a person either alone or under a surf suit or wet suit. In one embodiment the buoyancy vest 100 is pulled over the wearers head and meant to fit snuggly around the person's upper torso. The snug fit of the buoyancy vest 100 allows the user to be stream line in the water and does not allow water to sit between the inside of the vest 100 and the user's upper torso. In another preferred embodiment the buoyancy vest 100 opens down the middle of on the front side 106 by means of a zipper, Velcro or other type of attachment, see Fig. 3, so that the person wearing the vest can easily put it on and still allow for it to fit snuggly around the upper torso.

Referring to Figs. 1 and 2, the buoyancy vest 100 can have one or more pockets 110 on the front side 106 and/or back side 108. Referring to Fig. 3, the pockets 110 on the buoyancy vest 100 are configured to hold foam inserts 112. The buoyancy foam inserts 112 are placed into the pockets 110 allowing the person wearing the vest to control how buoyant they are in the water by chosing how many foam inserts 112 to place in the pockets. The foam can be inserted or removed to increase or decrease the buoyancy in the water. Thus one or more can be used and the size and density of the foam insets 112 can be changed. In the invention, the foam inserts 112 can be manufactured in various densities and thicknesses thereby allowing the wearer of the vest to further select how much buoyancy they desire. In one embodiment, the foam inserts 112 are a closed cell foam such as ethylene vinyl acetate ("EVA").

This buoyancy vest 100 is configured to be worn by a person who is bodysurfing so that they can control their buoyancy in the water, however this buoyancy vest 100 could be worn by anyone engaging in a number of types of water sports. The amount of buoyance is controlled by adding or taking out foam inserts from the vest's 100 pockets 110. Referring to Fig. 2, in one embodiment the back side 108 has an extension on lower end referred to as a tab 114. This tab 114 extends down and rests on the wearers glutious maximus and can be grabbed by the wearer to pull the vest up and over the wearers head for removal of the buoyancy vest 100. In some embodiments there is a string or rope 118 attached to the tab 114. This string 118 can be easily reached by the person wearing the vest 100 and therefore allows them to pull on the string 118 and pull the vest 100 up over their head to access the tab 114 and pull the vest over their head to remove.

The buoyancy vest 100 is preferably constructed from neoprene or other lightweight, stretchable, water, chemical and UV resistant material. In another preferred embodiment the buoyancy vest 100 is constructed from a buoyant material. For example, this material of the vest 100 maybe fabricated from neoprene in various thicknesses. In one embodiment, the thickness of the neoprene or buoyant material is from ½ to 20 millimeter. A thicker neoprene vest provides more buoyancy and allows the surfer to body surf in colder waters since neoprene keeps the body temperature elevated. Referring to Fig. 2 and 3, in the invention the front side 106 and the back side 108 have a right and a left panel 122 and 124. These panels have an additonal layer of neoprene on the inside of the vest which is stretched or glued to the inside of the vest around the circumference of the panel. The pockets 110 of the vest are then cut through the outside of the vest panel 122 and 124, and inserted between the two layers of neoprene formed by the panels 122 and 124. The buoyancy foam 112 can then slide into the pockets made in the panels 122 and 124, see Fig. 3. In a possible embodiment, each pocket has an exterior flap 126, which folds over the opening of the pocket and Velcros or attaches by other means to the exterior vest. These exterior flaps 126 cover the pockets so that the buoyancy foam 112 does not fall out.

The above description of disclosed embodiments is provided to enable any person skilled in the art to make or use the invention. Various modifications to the embodiments will be readily apparent to those skilled in the art; the generic principals defined herein can be applied to other embodiments without departing from spirit or scope of the invention. Thus, the invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principals and novel features disclosed herein.
