CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority to U.S. Provisional Application No. 61/919,085, entitled, “Hydrofoil Base for Additional Wings and Body Surfing Attachments” and is a continuation in part of U.S. patent application Ser. No. 13/328,478, filed Dec. 16, 2011, entitled, “Body Surfing Hydrofoil and Associated Methods”, which claims the benefit of U.S. Provisional Application No. 61/423,879, filed Dec. 16, 2010, entitled, “Body Surfing Enhancement Device and Associated Methods”, U.S. Provisional Application No. 61/475,999, filed Apr. 15, 2011, entitled, “Body Surfing Enhancement Device and Associated Methods”, and U.S. Provisional Application No. 61/486,029, filed May 13, 2011, entitled, “Body Surfing Enhancement Device and Associated Methods”, the disclosures of which are all hereby incorporated by reference herein in their entirety, and all commonly owned.


FIELD OF INVENTION
The present disclosure generally relates to aquatic sports and more specifically, to apparatuses for body surfing.
BACKGROUND
Surfboards are used to support a person while on top of the surface of water commonly known as “riding” a wave. It is also known to “body surf,” that is, to ride a wave without the use of a surfboard by stretching one's body out in as planar a configuration as possible and permitting oneself to be carried ashore by the wave.
Body surfers typically extend their bodies horizontally while projecting their arms forward and allowing a breaking wave to drive them shoreward with the surf. It is important to a body surfer to have a stable ride and to be able to control direction and position on a wave face. Because a body surfer typically avoids using a surf board, it is generally difficult to control stability, direction and position on a wave face. As a result, body surfing suits are popular. For a body surfing suit to work as desired, the suit should allow for ease in bending one's body in all natural directions of movement while swimming and providing buoyancy in a preferred location and position with respect to the surface of the water. Buoyancy should be greatest at the surfers chest and taper down toward the feet to ensure that the surfer enjoys the safest ride possible. It is also desirable to provide comfort during repeated and multiple rides. It is also desirable that the surfer be allowed to breathe easily during the entire water activity involving swimming, surfing, and vertical or horizontal rest periods.
While few body surfing suits are well known, typically upper body portions do not allow adequate body bending because of a rigid structure being employed and while buoyant materials are used, they are not strategically placed to provide a desirable experience. Further, while fins are employed, they are not typically sized or positioned to provide a synergy with the upper body portion of the suit for enhancing the wave surfing experience.
The present invention seeks to overcome limitations by providing the body surfer a means to stabilize his ride and control his direction and position on a wave while being able to experience multiple events while surfing without over exertion. Further, body surfing is known to be quite difficult and demanding on one's body, especially in more rigorous wave conditions. Therefore, it would be beneficial to provide an apparatus and method that enhances the body surfing experience even in such rigorous conditions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A detailed description of embodiments for a body surfing device having a base adapted for additional wings and body surfing attachments will now be presented with reference to FIGS. 1-42. One of skill in the art will recognize that these embodiments are not intended to be limitations on the scope, and that modifications are possible without departing from the spirit thereof. In certain instances, well-known methods, procedures and components have not been described in detail.
Embodiments of the present invention include a device for body surfing comprising a base that attaches to different sized and shaped wing attachments. Embodiments of the base provide cushion and stabilization to the wearer while providing a reinforced structure to allow attachment and use of different sized and shaped wing attachments. In use, the base can essentially serve to lift the chest of the wearer from the water.
As shown in FIGS. 1 and 2, body surfing device 100 comprises base 101 and wing attachment 102. Base 101 has top surface 101a and bottom surface 101b. When worn by a user, top surface 101a faces the user and bottom surface 101b faces the water. Base 101 also has front side 101c, back side 101d, right side 101e, and left side 101f. In use, front side 101c is the portion of base 101 nearest a user's head and back side 101d is the portion of base 101 near a user's waist. When worn, right side 101e would be on a user's right side and left side 101f would be on a user's left side. Base 101 can be generally trapezoidal in shape with front side 101c and back side 101d (although possibly being curved in shape) being generally parallel with each other, back side 101d being greater in length than front side 101c, and right side 101e and left side 101d (also possibly being curved in shape) extending between front side 101c and back side 101d at the ends of each of front side 101c and back side 101d. 
Wing attachment 102, which includes wing strut 103, steering fin 105, and wing extension 104, attaches to base 101 on bottom surface 101b at bracket 106. While wing strut 103 and wing extension 104 are rigidly attached to base 101, steering fin 105, which is rotatably connected to wing strut 103 along its length, can be allowed to freely rotate along its connection axis. As shown in FIG. 1, rotation can be provided by axel 120. Axel 120 can be rotatably mounted to steering fin 105 or to base 101. Axel 120 can run the length of steering fin 105. Rotation can be limited to provide stability. As shown in FIG. 3, stop blocks 121 can be used to limit rotation.
Bracket 106 can be any mounting device that mounts wing strut 103 to base 101. The mounting device can be a detachable mounting device. For example, bracket 106 can be a slide-and-self-lock style bracket that allows the user to slide wing attachment 102 into bracket 106 at an angle and then snap wing attachment 102 into a secure, roughly 90 degree position relative to bottom surface 101b of base 101. In another example, as illustrated in FIGS. 1 and 2, wing attachment 102 can be secured with fasteners at bracket 106.
Another exemplary wing attachment, wing attachment 120, is shown in FIG. 4. Here, an alternately shaped wing extension, wing extension 112, is mounted to base 101 by wing strut 118. Wing strut 118 has an extended ‘Z’ shape and is detachably affixed to base 102 at bracket 106.
As can best be seen in FIG. 2, separation members 107 are attached to top surface 101a of base 101. In use, separation members 107 rest against the user's chest. A third separation member (not shown in FIG. 2) can also be included between separation members 107. Separation members 107 can be made of buoyant material, such as foam. Separation members 107 can also serve as spacers or struts between the user's chest and base 101. Separation members 107 can help provide a hydrofoil effect by allowing water to flow between separation members 107 and between the user and top surface 101a of base 101 at a certain speed and allowing water to flow under base 101 (along bottom surface 101b) at a faster speed. This difference in water speed provides lift causing the user's chest to essentially be lifted over the water. The size and shape of separation members 107 and base 101 can vary. Further examples are described in later embodiments.
Also illustrated in FIGS. 2 and 4 is back cover 110 connected to base 101 via shoulder straps 108. Shoulder straps 108 are connected to base 101 at or near front side 101c. In use, back cover 110 would be worn on the user's back. Buoyant material can be added to back cover 110 to help prevent the user from rolling over onto his/her back in the water.
In addition to shoulder straps 108, back cover 110 can be connected to base 101 at upper waist strap 109. Upper waist strap 109 can be a stretchable material to allow the user to pull the device over his/her head and shoulders. Upper waist strap 109 can comprise a detachable connection, such as, for example, a parachute buckle. Upper waist strap 109 can connect to top surface 101a at or near left side 101f and at or near back side 101d. An additional upper waist strap (not shown) connecting back cover 110 and base 101 can be located at or near right side 101f and at or near back side 101d. 
Body surfing device 100 can also include lower waist strap 111, which can connect to top surface 101a of base 101 at or near left side 101f and at or near bottom side 101b. An additional lower waist strap (not shown) can be connected to top surface 101a of base 101 at near right side 101f and at or near bottom side 101b. Lower waist strap 111 can include a fastener to detachably connect lower waist strap 111 to a user's wetsuit. An exemplary wetsuit for use with embodiments described herein is shown in FIG. 34. As shown, wetsuit 615 includes wetsuit waist straps 617 that are affixed to wetsuit 615. Lower waist straps 111 can connect with wetsuit waist straps 617 to hold body surfing device 100 in place while in use. Alternatively, lower waist strap 111 and the waist strap attached at or near right side 101e can detachably connect with each other and be used to wrap around the user's back.
Openings 113 can be used to secure body surfing device 100 to a user's wetsuit or to back cover 110. Straps connected to a user's wetsuit can be threaded through openings 113, looped around top side 101c or right side 101e or left side 101f, as applicable, and removably connected (via, for example, a parachute buckle) to the back of a user's wetsuit. Openings (not shown) can also be located in shoulder straps 108 or back cover 110 and straps threaded through such openings before removably connecting them to the back of a user's wetsuit.
FIGS. 5A through 7 further detail the design of embodiments of a body surfing device base, such as, for example base 100. FIGS. 5A and 6A are top views of base 150 showing top surface 150a and FIGS. 5B and 6B are bottom views of base 150 showing bottom surface 150b. FIG. 5C is a view of base interior 154, which can be included in base 150 to provide a reinforced core interior.
In an exemplary embodiment, the outer body of base 150 is made from carbon fiber. The interior of base 150 can comprise rigid foam. Additionally, neoprene can be used to create a reinforced core interior, base interior 154, in the shape shown in FIG. 5C. Base interior 154 is fit in between the foam of interior base 150 such that openings 151a, 151b, and 151c line up with each other, openings 158a, 158b, and 158c line up with each other and bracket connectors 153a and 153b line up with each other. Shoulder straps can be fastened or sewn to base interior 154. Kevlar/carbon fiber cloth tweed and epoxy can also be located between the foam layers of base 150. Fill lines 152 can result from a chopped carbon fiber and epoxy slurry that can be run on top of base interior 154 to reduce flexing. Fill lines 152 can also be used for placement of separation members (as illustrated in FIG. 25)
In another exemplary embodiment, a piece of neoprene cut to the shape and size of base interior 154 is sandwiched between layers of foam. The neoprene may not extend the full length of the base. Wetted carbon fiber cloth can be used to join the two foam halves along with the other interior pieces. A second neoprene piece can be cut to the shape and size as base interior 154 and bonded to the outer foam that is facing the user's chest. Fiber cloth used to create shoulder straps can then be bonded on top of the neoprene and the exposed foam.
Upper internal structural element 160 provides support for upper waist connection 156, which can connect base 150 to an upper waist strap (e.g. FIG. 2, 109). Lower internal structural element 161 provides support for lower waist connection 157, which can connect base 150 to a lower waist strap (e.g. FIG. 2, 111). Wing connection structural element 159 provides support for bracket connection 153a, which can connect base 150 to a wing strut (e.g. FIG. 2 element 103). These structural reinforcements (upper internal structural element 160, lower internal structural element 161 and wing connection structural element 159) can be made of Kevlar®/carbon fiber cloth tweed and epoxy located between the foam layers of base 150. Today's extruded plastics technology includes the ability to use fibers in the liquid matrix before entering the mold. Manufacturing technologies like that, combined with air bladders or injected foams, can be used as substitutes for the Kevlar-carbon fiber foam construction described in embodiments herein.
FIG. 7 shows an alternative design of a base. The back side (side nearest the user's waist) of base 170 comes to two points.
FIGS. 8 and 9 depict hand-held wing 200 which can be used alone or in conjunction with body surfing devices described herein. Hand-held wing 200 can be held at arms-length independent of the body surfing device's base. Hand-held wing can assist a user with steering while in the water. Hand-held wing 200 includes wing base 201 having handles 202 on its top side (shown in FIG. 8) and fins 203 (shown in FIG. 9).
An embodiment of a body surfing device having a folding wing attachment is illustrated in FIGS. 10 through 13. In FIG. 10, body surfing device 210 having folding wing attachment 212 is shown positioned on base 211 in its unfolded or flat position. Folding wing attachment 212 has middle hinge 215 that allows left wing 214 and right wing 213 of folding wing attachment 212 to fold together about middle hinge 215. FIG. 11 shows a side view of folding wing attachment 212 folded about middle hinge 215.
Left wing 214 can then be folded along left hinge 217 and right wing 213 can be folded along right hinge 216 to form an upside down “T” shape as illustrated in the front view of FIG. 12. In the folded position, right wing extension 218 and left wing extension 219 are substantially parallel to the bottom surface of base 211. This allows the wearer to swim out with folding wing attachment 212 in the flat position (as shown in FIG. 10) to reduce drag and then fold the wings along the hinges to create the upside down “T” shape (as shown in FIG. 12) to ride the waves back to shore. Optionally, right brace 220 and left brace 221 can be hingedly attached to base 211. Right brace 220 and left brace 221 can removably attach to right wing 213 and left wing 214 respectively to provide added stability to folding wing attachment 212.
FIG. 13 depicts a bottom view of base with folding wing attachment 212 removed. Folding wing attachment 212 hingedly attaches to base 211 at middle hinge attachment area 215a. Cavities can be included in base 211 for the braces. Left brace cavity 222 can house left brace 221 and right brace cavity 221 can house can house right brace 220 when right wing 213 and left wing 214 are in their unfolded position.
Right wing extension 218 and left wing extension 219 may each include a thicker or protruding portion on its top side as shown in FIG. 12. Base 211 can include cavities to contain the protruding portion to allow folding wing attachment 212 to lay roughly flat when in the unfolded position. Left wing extension cavity 224 can house the protruding portion of left wing extension 219 and right wing extension cavity 223 can house the protruding portion of right wing extension 218.
Embodiments of the body surfing devices described herein can be used with and without a wetsuit. FIGS. 14 through 16 illustrate an embodiment that can be used with or without a wetsuit. As shown, body surfing device 300 includes base 302 connected to wing extension 301 by wing strut 303. Base 302 also includes shoulder straps 318. In an exemplary embodiment, shoulder straps 318 are made of stretchable neoprene. Shoulder straps 318 are connected at one end to base 302 at or near front side 302c. In an exemplary embodiment, shoulder straps 318 are connected to base 302 by sandwiching shoulder straps 318 between the foam core and fiber glass/epoxy resin layers of base 302. At their opposite ends, shoulder straps 318 are connected to opposing ends of back strap 317. Back strap 317 can, for example, be made of poly strapping.

Embodiments of the body surfing device described herein includes rotating leg fins and/or extendable wing attachments. Body surfing device 400 having rotating leg fins (405a and 405b) and extendable wing attachment 440 is shown in FIGS. 18 through 24. Although depicted in the same embodiment in FIGS. 18 through 24, the rotating leg fins (405a and 405b) and extendable wing attachment 440 can be implemented separately and/or in combination with features described with respect to other embodiments.
Body surfing device 400 comprises base 401, extendable wing attachment 440 having wing strut 403 and wing extension 404, rotating right leg fin 405a and rotating left leg fin 405b. The connections to shoulder straps 402 are also shown. Base 401 has top surface 401a and bottom surface 401b. When worn by a user, top surface 401a faces the user and bottom surface 401b faces the water. Base 401 also has front side 401c, back side 401d, right side 401e, and left side 401f. In use, front side 401c is the portion of base 401 nearest a user's head and back side 401d is the portion of base 401 nearest a user's waist. When worn, right side 401e would be on a user's right side and left side 401f would be on a user's left side.
Shoulder straps 402 can be connected to base 401 at or near front side 401c. Shoulder straps 402 can connect to a back cover similar to that shown in FIGS. 2 and 4 and described above. Shoulder straps 402 can also connect to a back strap similar to that shown in FIGS. 14 and 16 and described above. Additional back covers that can be connected to shoulder straps 402 are also described below with reference to FIGS. 33 and 35-37. Although not shown, an upper waist strap and/or a lower waist strap (as described with reference to FIGS. 2 and 4 above and FIGS. 25-31, 33, 35, and 36 below) can be included on base 401. Separation members (not shown), similar to those that described with reference to FIG. 2 above and FIGS. 25-31 and 36 and below, can also be included on base 401.
Rotating leg fins 405a and 405b can be rotated between a retracted position, as shown in FIGS. 19 and 21, and an extended position as shown in FIGS. 18, 20, 22 and 23. In their extended position, rotating leg fins (405a and 405b) can allow a user to more easily swim while wearing body surfing device 400. An example degree of extension that can allow the user room to swim is about 29 degrees; however, this can vary greatly according to a user's preference. In their retracted position, rotating leg fins (405a and 405b) provide the user with an area to rest their legs on while surfing. The degree of rotation of rotating leg fins (405a and 405b) in their retracted position can vary as well. Rotating leg fins (405a and 405b) help reduce or eliminate the drag effect of a user's legs trailing at a different height than their torso when the hydrofoil effect lifts the upper body out of the water.
As best shown in FIG. 18, rotating left leg wing 405b is rotatably connected to depressed area 401g of top surface 401a of base 401 located near back side 401d and left side 401f. Similarly, rotating right leg wing 405a is rotatably connected to depressed area 401h of top surface 401a of base 401 located near back side 401d and right side 401e. The placement of rotating leg fins 401a and 401b on top surface 401a is exemplary. Rotating leg fins 401a and 401b can also be located on bottom surface 401b or in a cutout of base 401 located between top surface 401a and 401b. The later modification can be done to the embodiment shown in FIG. 18 by continuing top surface 401a over rotating leg fins 401a and 401b. Rotating leg fins 401a and 401b extend outward from base 401. Rotating leg fins 401a and 401b may include a circular portion and a modified (curved) rectangular portion. The size and shape of each portion of rotating leg fins 401a and 401b is exemplary.
The attachment and rotation mechanism for rotating leg fins 405a and 405b illustrated in the embodiment shown in FIGS. 18 through 23 is exemplary. In this exemplary embodiment, the attachment and rotation mechanism will be described with reference to rotating left leg fin 405b. One of ordinary skill in the art will appreciate that rotating right fin 405a is similarly attached, but to rotate in the opposite direction. As best shown in FIGS. 21 and 22, which are partial views of base 401 showing its connection to left leg fin 405b, rotating left leg fin 405b is rotatably connected to base 401 about axel 410. Axel 410 is connected to bracket 412. Bracket 412 includes track pins 411 that are in sliding communication with tracks 407. As track pins 411 move along tracks 407, bracket 412 causes axel 410 to rotate. Axel 410, being rigidly attached to rotating left leg fin 405b, causes rotating left leg fin 405b to rotate. Spacer 413 is optional and can freely rotate about axel 410. Spacer 413 can have a smooth surface and be used to reduce friction between bracket 412 and bottom surface 401b. 
Rotation of rotating leg fins (405a and 405b) can be limited in their degree of rotation relative to base 401. In this exemplary embodiment, tracks 407, are used to limit the degree of movement of rotating left leg fin 405b. Tracks 407 can limit rotation when rotating left leg fin 405b is retracted as shown in FIG. 21 and when rotating left leg fin 405b is extended as shown in FIG. 22. Tracks 407 can be extended in length to provide a greater degree of movement to rotating left leg fin 405b. 
Rotation of rotating leg fins (405a and 405b) can also be locked in placed in various positions to prevent movement during use. In this exemplary embodiment, rotating left leg fin 405b can be locked in place in a first (retracted) position as shown in FIG. 21 and in a second (extended) position as shown in FIG. 22. In the first position, first connector 409 using spring-loaded first connector pin 415 engages with receiving portion 414 of bracket 412. To engage with receiving portion 414 of bracket 412, first connector pin 415 is in its uncompressed state. To unlock rotating left leg fin 405b from the first position, first connector pin 415 can be compressed, disengaging first connector pin 415 from receiving portion 414 of bracket 412. Rotating left leg fin 405b can then be rotated to its second position, as shown in FIG. 22. In the second position, second connector 408 using spring-loaded second connector pin 416 engages with the receiving portion 414 of bracket 412. To engage with receiving portion 414, second connector pin 416 can be allowed to move to in its uncompressed state. To unlock rotating left leg fin 405b from the second position, second connector pin 416 can be compressed, disengaging second connector pin 416 from receiving portion 414 of bracket 412.
Extending wing attachment 440, which is best shown in FIGS. 19, 20, 23, and 24, includes wing strut 403 and wing extension 404. Wing strut 403 is positioned on base 401 on bottom surface 401b. Wing extension 404 can be mounted on wing strut 403 in multiple positions or can be removed altogether (and replaced with another wing extension). Although wing extension 404 can be mounted in any number of positions, two positions are illustrated here. The first (retracted) position is shown in FIGS. 19 and 20. The second (extended) position is shown in FIG. 23. An exploded view, also illustrating wing extension 404 completely removed from wing strut 403, is shown in FIG. 24. Wing extension 404 includes a plurality of extension members positioned thereon—locking extension member 430 and secondary extension members 431, 432, and 433. Although four extension members are shown here, any number of extension members can be used including only one extension member. If greater distance between base 401 and wing extension 404 is desired, the length of extension members 430-433 can be increased. Locking extension member includes aperture 434. Wing strut 403 includes a plurality of openings—primary opening 438 and secondary openings 435-337—to receive extension members 430-434. Although four openings are shown here, any number of openings can be used. There should just be at least as many openings as extension members.
To lock wing extension 404 in the first position, extension members 430-434 are placed into their respective openings 435-438 and positioned so that first hole 447 (best shown in FIG. 23) lines up with aperture 434. Primary locking pin 441 having open portion 441a (best shown in FIG. 24) can be threaded through first hole 447 and through aperture 434. First lock 443, located adjacent to first hole 447, using first lock pin 442, can be moved to engage with open portion 441a of locking pin 441. First lock pin 442 can then be rotated to further engage with first lock 443 securing wing extension 404 in its first position.
To lock wing extension 404 in the second position (shown in FIG. 23), extension members 430-434 are placed into their respective openings 435-438 and positioned so that second hole 446 (best shown in FIGS. 19 and 20) lines up with aperture 434. Primary locking pin 441 can be threaded through second hole 446 and through aperture 434. Second lock 445, located adjacent to second hole 446, using second lock pin 444, can be moved to engage with open portion 441a of locking pin 441. Second lock pin 444 can then be rotated to further engage with second lock 445 securing wing extension 404 in its second position.

The addition of separation member 521 can help enhance the aileron effect of base waist straps 525 (described below) and base chest straps (described below) 526 that can occur when body surfing device 520 is in use.
The separation members of any embodiment described herein can be made of buoyant material, such as foam. The separation members can serve as spacers or struts between the user's chest and the base of the body surfing device. The separation members can help provide a hydrofoil effect by allowing water to flow between the separation members and between the user and the top surface of the base at a certain speed and allowing water to flow under the base (along bottom surface) at a faster speed. This difference in water speed provides lift causing the user's chest to essentially be lifted over the water. The separation members can also be made of a compressible material, which would expand and contract with a user's breathing. The arrangement of separation members can be any arrangement that provides distance between the user and the body surfing device's base. The arrangement can also be made to provide a comfortable experience for the user. Aside from the arrangement shown and described above, another exemplary arrangement would be separation members in the shape of a triangle with the base of the triangle near the front side of the base. The separation members can be separate pieces attached to the base or can be blow molded and formed as part of the base.

The components of the electro magnets are fully encapsulated in a water proof container. The electro magnet is an electroshock technology created using a step-up transformer or step-up solid state device that converts a small voltage battery (e.g. 12V) to a high voltage (e.g. 2,000V) at a high frequency. The stepped-up output is attached to a copper or copper alloy coil creating an ‘always on’ circuit. The pulse frequency of the electro magnet can be altered to deliver a long lasting battery charge. An additional ‘emergency’ circuit can also be included that is in parallel to the ‘always on’ circuit. This circuit can be activated manually and will provide an additional voltage to the electro magnet to greatly increase the voltage (e.g. 20,000V).
The combination of elements of each of the embodiments described herein should not be construed as limiting. Many of the elements of the embodiments described herein can be used in different combinations. For example, the base and back cover combination described with reference to FIGS. 1-2 and 4 could be combined with the extendable wing attachment described with reference to FIGS. 18-20 and 23-24. As another example, leg fins of FIG. 25 or rotating leg fins of FIGS. 18-23 could be added to the base of the body surfing devices 100, 150, 210, 300 or the leg fins of body surfing devices 500, 515, 520, 550, 570, 580, 600 could be replaced with rotating leg fins of FIGS. 18-23.
Having now described the invention, the construction, the operation and use of preferred embodiments thereof, and the advantageous new and useful results obtained thereby, the new and useful constructions, and reasonable mechanical equivalents thereof obvious to those skilled in the art, are set forth in the appended claims.
