Description

FIELD OF THE INVENTION

The invention relates to flotation devices, and specifically relates to a device designed to provide open water swimmers with a stronger and safer swim by delivering safety, support and strength, without hindering performance or stroke.

BACKGROUND OF THE INVENTION

In recent years there has been a rise in the popularity of open water swimming. Many triathlons begin with an open water swim and there are several stand-alone competitive open water swimming competitions each year in the United States. Open water swimming reached a new level of international exposure by becoming an official event at the 2008 Olympic Games in Beijing, China.

Training for open water swimming events presents a unique set of challenges. Swimming in open water shared by boaters, jet skiers and other human hazards presents certain safety issues. Unlike swimming in a pool where a swimmer is generally no more than four lanes away from a wall, open water swimming may place a swimmer hundreds or yards, or even miles from shore or any means of support or flotation in the event of cramps, dizziness or injury. Participants in distance events on land, such as cycling and running, generally have ready access to hydration and nutrition during their event, either through food and water carried on the participant or bicycle or at nutrition and hydration stations that can be quickly and easily set up along the race or training course. In open water swimming, there is nowhere for the swimmer to carry hydration and nutrition during the open water swim, and setting up nutrition and hydration stations in the water can be difficult.

One product that is currently on the market that addresses some of these concerns is the ISHOF SaferSwimmer™ Float (http://www.ishof.org/safety/ssd.htm). While the Safer Swimmer Float addresses safety and visibility concerns, as well as dry-bag storage for the swimmers personal effects, it does not provide a way for the swimmer to quickly and easily obtain nutrition and hydration during an open water swim. Another product, the Goat Gear Aquaspotter™ (http://getgoatgear.com/content/aquaspotter), provides visibility to open water swimmers, but does not address the issues of safety, hydration and nutrition.

SUMMARY OF THE INVENTION

The present invention provides open water swimmers a stronger and safer swim by delivering all three critical benefits, without hindering performance or stroke. The present invention provides safety by making the swimmer visible to boaters, jet skis, or other potential human hazards. Support in the form of flotation for rest, cramps, dizziness or injury is provided as well. The device can also provide support to others when needed in a group swim. This support also provides greater comfort and security to the open water swimmer allowing him or her to push further because of the confidence it provide to the swimmer in having the perfect swim buddy right next to him or her and able to help. Finally, the present invention provides strength to the open water swimmer by holding hydration and nutrition for longer swims. The present invention allows the open water swimmer to carry needed water and nutrition to help him or her go longer and stronger as well as faster recovery.

According to one aspect of the present invention an open-water swim training device is provided comprising a buoyant body having a tapered front end and an opening positioned in an upper surface thereof for removably receiving nutrition and/or hydration. A first end of a tether is connected to the tapered front end of the buoyant body. A waistband for removably connecting the training device to a swimmer is connected to a second end of the tether. A visibility marker is also affixed to the buoyant body.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIGS. 1-3 illustrate an open water swim training device 10 according to a presently preferred embodiment of the present invention. As shown in FIG. 1, the open water swim training device 10 includes a buoyant body 12 connected to a waistband 14 by tether 16. The open water swim training device 10 is also provided with a visibility marker 18 to make the swimmer visible to boaters, jet skiers and other potential human hazards.

The safety function of the open water swim training device 10 is performed primarily by the visibility marker 18, which includes a flexible wire 19 having a first end connected to the buoyant body 12 near a first end thereof, and a second end connected to the buoyant body 12 near a second end thereof. One or more colored flags 20a, 20b may be located at positions along the flexible wire 19 to provide a visual marker for boaters, jet skiers and other watercraft. The flags 20a, 20b may be of any bright color, such as red, white, orange or yellow that may attract the attention of other watercraft operators. Alternatively, or in addition, other visual means, such as strobe lights (not shown), may be used to attract the attention of other watercraft in the area of the swimmer. In addition, the flexible wire 19 doubles as a shoulder strap for carrying the open water swim training device 10 to and from the swimming area.

The buoyant body 12 is preferably formed of a dense, durable foam material, such as polyethylene closed-cell foam, which provides superior buoyancy characteristics, superior strength and tear resistance, and is impervious to mold, mildew and rot. According to one preferred embodiment, the buoyant body 12 is a cylinder approximately 6 inches in diameter, and 29 inches in length, and is capable of keeping an adult weighing up to 200 lbs. afloat. As can be appreciated, different sizes and dimensions can be utilized to accommodate larger or smaller swimmers. The buoyant body 12 also has a tapered front end 22 which cuts down on drag, allows the buoyant body 12 to cut through even choppy water with relative ease. The tapered front end 22 also facilitates tracking of the buoyant body 12 behind the swimmer as he or she passes through the water.

The buoyant body 12 also includes an opening, or center console 24 located near the midportion thereof and configured to receive hydration and/or nutrition therein. As shown in FIG. 1, according to a presently preferred embodiment of the invention, an opening approximate three inches wide is provided in the center console 24 for receiving a water bottle 26. The water bottle 26 is held in place by frictional engagement with the walls of the center console 24, which are formed of closed cell foam having a degree of flexibility that allows the water bottle 26 to be held tightly in place during swimming, but allows the swimmer to quickly and easily remove the water bottle 26 from the center console 24 while in the water to get a drink. As can be readily appreciated, the size of the opening in the center console can vary to accommodate water bottles of varying sizes and shapes as well as containers for food. The center console 24 is also designed to be self draining The bottom surface of the center console is sloped from the front of the buoyant body 12 toward the rear thereof such that the water naturally pools at the rear portion of the center console 24. A drain hole is located in the center console 24 at the rear end thereof allowing water to drain through the buoyant body 12 and return to the body of water. As the buoyant body 12 is pulled through the water by a swimmer, water that enters the center console 24 is naturally directed toward the lower rear end portion of the center console 24 where it enters the drain hole and returns to the body of water.

As best shown in FIG. 3, and in order to ensure that the water bottle 26 located in the center console 24 remains above water and is not lost due to overturning of the buoyant body 12, ballast 28 is provided in the buoyant body 12. The ballast 28 is provided in the lower region of the buoyant body 12 opposite the center console 24 permitting constant self-centering of the buoyant body 12 as it is pulled through the water by the swimmer. The ballast 28 may comprise a steel bar or other suitable material having sufficient weight to perform the self-centering function and prohibit the buoyant body 12 from overturning during the swim and dislodging the water bottle 26 from the center console 24.

The tether 16 connects the waistband 14 to the tapered front end 22 of the buoyant body 12, and is also comprised of a buoyant material that allows it to float on the surface of the water. According to one preferred embodiment, the tether 16 is formed of nylon rope. By providing a tether 16 that floats, entanglement with the swimmers legs while kicking is effectively avoided.

As best shown in FIG. 2, the waistband 14 includes a strap 30 configured to wrap around the waist of the swimmer. Male and female clip members 32, 34, respectively are positioned at each end of the strap 30 allowing for quick and easy attachment to and removal from the swimmer. The length of the strap 30 can be adjusted at either of the clip members to accommodate swimmers of varying sizes. Additional flexibility and comfort is built into the strap 30 by the providing of an elastic cord 36, which extends through a portion of the strap 30. The amount of stretch in the elastic cord 36 can be adjusted by a pair of cord locks 38a, 38b provided near opposing ends of the elastic cord.

FIGS. 4-13 illustrate an open water swim training device 110 according to an alternative presently preferred embodiment of the invention. The open water swim training device 110 shown in FIGS. 4-13 is similar to the open water swim training device shown in FIGS. 1-3 wherein like reference numeral indicate like components.

As shown in FIG. 5, according to a presently preferred embodiment of the invention, a flat, bag-style water bottle 126 is removably located within the buoyant body 112. The water bottle 126 shape conforms to the bottom of the lower hull 112b. A tube or straw 125a has a first end connected to the water bottle and a second free end that passes through a hole in the upper hull 112a to deliver liquid refreshment to a swimmer. Straw outlet grommet 127 provides a water tight seal around the straw as it passes through the hole in the upper hull 112a. A straw cap 125b prevents contamination from entering into the drinking water or liquid in the water bottle 126.

A removable storage compartment 140 is positioned within the opening 124 and, upon removal, allows access to the water bottle 126 for removal, cleaning and/or refilling, and access to the inside of the buoyant body 112 for cleaning An adhesive water seal 142 may be attached to the underside of a lip on the removable storage compartment 140 to ensure a water-tight seal when the removable storage compartment 140 is seated in the opening 124. The removable storage compartment 140 can be used to store nutrition and or personal gear of the swimmer. A removable cargo storage lid 144 may be placed over the opening in the removable storage compartment 140 when in use. A water seal end bulb 146 is attached to a lower side of the lid 144 to ensure a water-tight seal.

As best shown in FIG. 5, and in order to ensure that the buoyant body 112 remains upright with the upper hull 112a, and access to the storage compartment 140 above water, ballast is provided in the buoyant body 112. The ballast is provided in the lower hull 112b of the buoyant body 112 permitting constant self-centering of the buoyant body 112 as it is pulled through the water by the swimmer. The ballast may comprise a heavy rod 128, preferably formed of metal, which acts as a counter weight, and a foam safety ballast 129 positioned above the rod 128 such that the rod 128 is held in place against the lower hull 112b. A quick drain plug 115 may be provided in the rear end of the lower hull 112b to remove water that inadvertently enters the interior of the buoyant body 112.

As best shown in FIGS. 11 & 12, when a swimmer is in deep water and is in need of hydration, her or she may go to the rear of the buoyant body 112, remove the straw cap 125b, and drink liquid from the water bottle 126 through straw 125a. To aid the swimmer in this process, finger grips 150 in the form of a molded in ridge may be provided in the upper hull 112a in the area of the opening 124. The finger grips may be located along both sides of the opening 124. When a swimmer is in need of rest, he or she can rest his or her arms on the upper hull 112a as shown in FIG. 13. The buoyant body 112 will support the swimmer's weight as he or she rests.
