Definitions
- the present invention relates to hydroplane boards or skim boards and, more particularly, to a topside rail or bumper structure for a circular hydroplane board for enhanced performance and safety.
- U.S. Pat. No. 6,671,602 discloses a circular hydroplane board for skimming along a surface at the water's edge.
- the circular hydroplane board has a substantially planar bottom side and a substantially planar top side connected by a smoothly curved circular-shaped lower side rail.
- the diameter of the board's bottom side is smaller than the diameter of the board's top side.
- the hydroplane board is best used for recreational hydroplaning, or skimming, along a beach or other smooth waterfront area.
- a user pushes the hydroplane board with his or her foot in a desired direction. Then the user walks, jogs, or runs toward the hydroplane board and jumps onto it while simultaneously exerting forward and downward forces onto the hydroplane board. The transfer of momentum from the user to the hydroplane board and the weight of the user induces hydroplaning. Normally, the circular hydroplane board hydroplanes at a speed much greater than the individual speed of the hydroplane board or user.
- the circular hydroplane board is extremely efficient due to its curved side rail and round periphery.
- the curved side rail minimizes forward friction, especially during initial contact between the user and the hydroplane board.
- the round periphery also reduces friction and facilitates forward motion even if the hydroplane board slews or moves in a radial direction.
- the force of friction between the user's feet and the topside of the circular hydroplane board and a layer of water over the hydroplane board's topside limits the forward force that may be applied to the hydroplane board. If the forward force exceeds the frictional force, the user will likely lose contact with the hydroplane board. This, in turn, limits the acceleration and speed of the combined hydroplane board and user. Second, the radial force that the user may apply to the hydroplane board is restricted. Thus, there is a need for a structural enhancement of the circular hydroplane board, which diminishes or overcomes these limitations.
- the outer edge or perimeter of the circular hydroplane board can be relatively sharp, which poses a potential hazard to bystanders if the user loses control of the hydroplane board.
- the outer edge of the circular hydroplane board includes no means of shock absorption in the event of a collision between a person or object and the moving hydroplane board.
- the present invention is a circular-shaped hydroplane board comprising a topside device attached to the top side of the hydroplane board.
- the present invention is a topside device for attachment to the top side of a circular hydroplane board, such as a speed rail and/or a bumper that encircles the outer circumference of the top side of a circular skim board. Alternate configurations of these topside devices are also included herein.
- the topside device of the present invention is a performance and safety enhancement.

- the bumper portion 13 a of the combined topside device 20 also extends outwardly from the topside outer edge 12 of the board.
- the speed rail portion 14 a extends around the inner side of the bumper portion 13 a.
- the topside device 20 on the circular hydroplane board preferably comprises both a speed rail portion 14 a and a bumper portion 13 a , which may be combined (into one structure), as illustrated in FIG. 3 , or separate from one another (see FIG. 7 ).
- a circular hydroplane board herein may include either a bumper or a speed rail.
- the bumper acts as a shock absorber and cushions any impact that occurs between the hydroplane board 10 and another person or inanimate object, such as a rock, a piling, or driftwood lying on a beach.
- the bumper covers and cushions the outer edge 12 of the hydroplane board. The edge is therefore less likely to chip or crack when it strikes a hard object.

- the arch-shaped speed rail 14 gradually slopes upwardly from the top side 11 b of the board until it reaches an apex 23 , at which point it gradually slopes downwardly from the apex 23 until it reaches the topside rail outer edge 24 .
- the topside rail outer edge 24 also contacts the top side 11 b of the hydroplane board 10 .
- the speed rail 14 is centered on the hydroplane board 10 near its edge.

- the bumper 13 is adjacent to the speed rail 14 .
- the bumper inner edge 15 contacts the top side of the hydroplane board 10 .

- the apex 17 of the bumper gradually curves downwardly towards the top side 11 b again, before turning inwardly to meet and engage the hydroplane board 10 .
- An outer, rounded edge 19 of the bumper 13 obscures the relatively sharp, outer edge 12 of the board, thus protecting bystanders from contact with a loose, flying hydroplane board, and incidentally protecting the hydroplane board from contact with a hard object, such as a rock.
- the bumper 13 is preferably hump-shaped, and extends around the periphery of the hydroplane board.
- the width of the bumper 13 from the outer, rounded bumper edge 19 to the inner bumper edge 15 , is between about three and about four inches, most preferably about two inches.
- the exposed bumper edge 19 is oriented substantially perpendicularly to the top side 11 b of the board.

- the forward force cannot exceed the maximum frictional force between the user's feet and the top side of the board. If the forward force exceeds the maximum frictional force, the user loses contact with the hydroplane board. Without meaning to be bound by theory, it is believed that the present topside device 20 removes this maximum frictional force limit.
- the topside device 20 is advantageous in that it changes the vector between the user's feet and the top side 11 b to an ideal 90 degrees.

- the topside rail inner edge 21 meets the top side at an obtuse angle.
- the speed rail 14 , 14 b - d may be generally concave, convex, or planar.

- Preferred embodiments of the hydroplane board 10 have a bottom side diameter of between about one and about two inches less than the top side diameter, and a thickness of about half the difference between the bottom side and top side diameters.
- the hydroplane board 10 is not intended to be towed behind a boat or the like, so the hydroplane board 10 does not comprise a towing means, seating means, or steering means. Rather, the hydroplane board 10 is utilized for personal skim boarding, or hydroplaning, along an edge of a body of water, such as the ocean or lake shore.
- the hydroplane board is not intended for surfing, and preferably does not include a skeg or any other attachment to the bottom side of the hydroplane board.

- the user may further spin the hydroplane board 10 in the shallow water, holding the hydroplane board 10 in place in the water with centripetal force, then pushing the hydroplane board forward.
- the user may spin the hydroplane board 10 with his or her foot.
- the topside device of the present invention facilitates these movements.

- the speed rail portion 14 a extends around the inner side of the bumper portion 13 a .
- the combined topside device 20 is attachable to a circular hydroplane board as depicted in FIGS. 1 and 3 .

- the bumper portion 13 a of the combined topside device 20 acts as a shock absorber and cushions any impact that occurs between the hydroplane board 10 and another person or inanimate object, such as a rock, a piling, or driftwood lying on a beach.
- the bumper portion 13 a cushions the relatively sharp, outer edge 12 of the hydroplane board, so the edge is less likely to chip or crack when the board strikes a hard object. If the hydroplane board 10 with its bumper collides with a person, the wide, rounded, soft bumper hits the person rather than the relatively sharp, outer edge 12 of the hydroplane board.
- the topside device 20 prevents injuries.
- the speed rail portion 14 a provides the user with an angled foothold for comfortable and secure landings and enhanced control of the hydroplane board. It allows the user to jump onto the moving hydroplane board without losing his or her balance or overrunning the moving board.

Description
- 1. Technical Field
- The present invention relates to hydroplane boards or skim boards and, more particularly, to a topside rail or bumper structure for a circular hydroplane board for enhanced performance and safety.
- 2. Background Information:
- U.S. Pat. No. 6,671,602, Quinn, issued Jul. 13, 2004 discloses a circular hydroplane board for skimming along a surface at the water's edge. The circular hydroplane board has a substantially planar bottom side and a substantially planar top side connected by a smoothly curved circular-shaped lower side rail. The diameter of the board's bottom side is smaller than the diameter of the board's top side. The hydroplane board is best used for recreational hydroplaning, or skimming, along a beach or other smooth waterfront area.
- In order to use the circular hydroplane board, a user pushes the hydroplane board with his or her foot in a desired direction. Then the user walks, jogs, or runs toward the hydroplane board and jumps onto it while simultaneously exerting forward and downward forces onto the hydroplane board. The transfer of momentum from the user to the hydroplane board and the weight of the user induces hydroplaning. Normally, the circular hydroplane board hydroplanes at a speed much greater than the individual speed of the hydroplane board or user.
- The circular hydroplane board is extremely efficient due to its curved side rail and round periphery. The curved side rail minimizes forward friction, especially during initial contact between the user and the hydroplane board. The round periphery also reduces friction and facilitates forward motion even if the hydroplane board slews or moves in a radial direction.
- However, the force of friction between the user's feet and the topside of the circular hydroplane board and a layer of water over the hydroplane board's topside limits the forward force that may be applied to the hydroplane board. If the forward force exceeds the frictional force, the user will likely lose contact with the hydroplane board. This, in turn, limits the acceleration and speed of the combined hydroplane board and user. Second, the radial force that the user may apply to the hydroplane board is restricted. Thus, there is a need for a structural enhancement of the circular hydroplane board, which diminishes or overcomes these limitations.
- The outer edge or perimeter of the circular hydroplane board can be relatively sharp, which poses a potential hazard to bystanders if the user loses control of the hydroplane board. Also, the outer edge of the circular hydroplane board includes no means of shock absorption in the event of a collision between a person or object and the moving hydroplane board. Thus, there is a need for a structural enhancement for the circular hydroplane board in order to reduce the chance and/or severity of injury and absorb shock in any accidental collisions between a person or object and the moving hydroplane board.
- The present invention is a circular-shaped hydroplane board comprising a topside device attached to the top side of the hydroplane board. Alternatively, the present invention is a topside device for attachment to the top side of a circular hydroplane board, such as a speed rail and/or a bumper that encircles the outer circumference of the top side of a circular skim board. Alternate configurations of these topside devices are also included herein. The topside device of the present invention is a performance and safety enhancement.

FIG. 17 is a top plan view of a topside device according to the present invention, showing rail segments. - In the following description, like reference characters designate like or corresponding parts throughout the several views. Also, in the following description, it is to be understood that such terms as “front,” “back,” “within,” and the like are words of convenience and are not to be construed as limiting terms. Referring in more detail to the drawings, the invention will now be described.
- The present invention includes a generally circular-shaped hydroplane, or skim,
board 10 comprising atopside device 20. The circular-shaped hydroplane board 10 has a substantially planar,bottom side 11 a and a substantially planar,top side 11 b terminating at an outer edge, orlip 12. Referring first toFIGS. 1 through 3 , thetopside device 20 extends along the topsideouter edge 12 of thecircular hydroplane board 10, and defines the periphery of the hydroplane board when viewed from the top of the board (seeFIG. 1 ). In this embodiment, thetopside device 20 comprises a combinedbumper portion 13 a andspeed rail portion 14 a, and extends upwardly from thetop side 11 b of the hydroplane board. Thebumper portion 13 a of the combinedtopside device 20 also extends outwardly from the topsideouter edge 12 of the board. Thespeed rail portion 14 a extends around the inner side of thebumper portion 13 a. - The
topside device 20 on the circular hydroplane board preferably comprises both aspeed rail portion 14 a and abumper portion 13 a, which may be combined (into one structure), as illustrated inFIG. 3 , or separate from one another (seeFIG. 7 ). Alternatively, a circular hydroplane board herein may include either a bumper or a speed rail. The bumper acts as a shock absorber and cushions any impact that occurs between thehydroplane board 10 and another person or inanimate object, such as a rock, a piling, or driftwood lying on a beach. The bumper covers and cushions theouter edge 12 of the hydroplane board. The edge is therefore less likely to chip or crack when it strikes a hard object. If thehydroplane board 10 with its bumper collides with a person, the wide, rounded, soft bumper hits the person rather than the hardouter edge 12 of the hydroplane board. The user or bystander is unlikely to be cut by the soft edge of the hydroplane board bumper. Thus, thetopside device 20 prevents injuries. -
FIGS. 4 through 7 depict a hydroplane board with atopside device 30 comprising abumper 13 along the edge of the hydroplane board, and aseparate speed rail 14. As seen inFIG. 6 , thespeed rail 14 comprises a sloped topside railinner edge 21, which is in contact with thetop side 11 b of thehydroplane board 10. As seen inFIG. 6 , the arch-shapedspeed rail 14 gradually slopes upwardly from thetop side 11 b of the board until it reaches an apex 23, at which point it gradually slopes downwardly from the apex 23 until it reaches the topside railouter edge 24. The topside railouter edge 24 also contacts thetop side 11 b of thehydroplane board 10. Thespeed rail 14 is centered on thehydroplane board 10 near its edge. When viewed from the top, the topside railinner edge 21,apex 23, and topside railouter edge 24 form concentric circles, with the topside railinner edge 21 as the innermost circle, the topside rail outer edge 25 as the outermost circle, and the apex 23 in the middle (seeFIGS. 4 and 7 ). - Continuing with
FIGS. 4 through 7 , thebumper 13 is adjacent to thespeed rail 14. The bumperinner edge 15 contacts the top side of thehydroplane board 10. The bumperinner edge 15 is centered on thetop side 11 b of thehydroplane board 10 such that it is encircled by and concentric with theouter edge 12 of the board. Thebumper 13 gradually curves upwardly and outwardly from thetop side 11 b of the board. The bumper exposededge 19 extends beyond the outer edge of the board, and engages the outer edge, or lip, 12 of thehydroplane board 10, which is preferably flat to facilitate adhesion of the bumper (seeFIG. 6 ). As seen inFIG. 7 , thebumper 13 obscures the relativelyouter edge 12 of the board. Thebumper 13 may have a greater height than thespeed rail 14, or vice versa, or they may be approximately the same height as seen inFIG. 6 . - As illustrated in
FIG. 6 and 7, anannular space 26 may exist between thebumper 13 and thespeed rail 14. Alternatively, thespeed rail 14 may transition into thebumper 13 without an intervening space. -
FIG. 8 depicts a circular hydroplane board with abumper 13 only. Theinner edge 15 of thebumper 13 contacts thecircular hydroplane board 10 on thetop side 11 b. The outer edge of thebumper 13 extends out over theouter edge 12 of the board. The exposededge 19 of thebumper 13 gradually curves upwardly from the top side outer edge of theboard 12. At a point approximately above theouter board edge 12, the apex 17 of the bumper gradually curves downwardly towards thetop side 11 b again, before turning inwardly to meet and engage thehydroplane board 10. An outer, roundededge 19 of thebumper 13 obscures the relatively sharp,outer edge 12 of the board, thus protecting bystanders from contact with a loose, flying hydroplane board, and incidentally protecting the hydroplane board from contact with a hard object, such as a rock. - The
bumper 13 is preferably hump-shaped, and extends around the periphery of the hydroplane board. Preferably, the width of thebumper 13, from the outer,rounded bumper edge 19 to theinner bumper edge 15, is between about three and about four inches, most preferably about two inches. As seen inFIG. 8 , the exposedbumper edge 19 is oriented substantially perpendicularly to thetop side 11 b of the board. The bumper is preferably about ¼ inch to one inch in height (above thetop side 11 b of the hydroplane board 10). - The
topside device 20 is preferably manufactured separately from thehydroplane board 10 and attached thereto using a suitable waterproof adhesive, for example. Alternatively, thetopside device 20 and thehydroplane board 10 may be formed from a single piece of material. Where thetopside device 20 is separate from the hydroplane board, it may be attached to the board by any conventional means including, but not limited to, glue, adhesive, nails, and screws. Thetopside device 20 may be made of rubber, wood, or a composite material. - The
speed rail 14 allows the user to exert a greater forward force on thehydroplane board 10 when he/she mounts thehydroplane board 10, enabling the user to increase forward velocity. In order to use any skim or hydroplane board, the user runs and jumps onto its top side. When the user's feet contact the top side, his/her forward motion or force (his/her mass×his/her instantaneous acceleration), and therefore his/her instantaneous velocity, is translated to the hydroplane board. However, the user's ability to maintain contact with the top side limits the forward force and instantaneous velocity. The forward force cannot exceed the maximum frictional force between the user's feet and the top side of the board. If the forward force exceeds the maximum frictional force, the user loses contact with the hydroplane board. Without meaning to be bound by theory, it is believed that thepresent topside device 20 removes this maximum frictional force limit. - It is believed that the
topside device 20 is advantageous in that it changes the vector between the user's feet and thetop side 11 b to an ideal 90 degrees. Thetopside device 20 directs the user's forward force vector entirely into thehydroplane board 10. Thus, a user with a given mass can apply a greater instantaneous velocity to thehydroplane board 10. Similarly, a user applying a given instantaneous velocity to thehydroplane board 10 may have a greater mass. - The combined
topside device 20 also provides a surface for application of minor radial forces by the user. Thedevice 20 provides a surface for bracing the user against centripetal forces. It provides a surface for off-center application of the user's forward force vector. This facilitates simultaneous spinning and skimming of the circular hydroplane board. -
FIG. 9 shows a circular board with aspeed rail 14 only. A secondannular space 32 lies between theouter edge 12 of the board and thespeed rail 14.FIGS. 9 through 12 show several possible variations of thespeed rail 14. On the hydroplane board shown inFIG. 9 , thespeed rail device 14 gradually slopes upwardly to the apex 23 and then gradually slopes downwardly to the topside railouter edge 24. Thespeed rail device 14 is generally convex between the topside railinner edge 21 and the apex 23 and the apex 23 and the topside railouter edge 24, respectively. The topside rail inner andouter edges top side 11 b at obtuse angles. Thespeed rail device 14 provides the user with a 90 degree angle for comfortable and secure landings. It allows the user to jump onto the moving hydroplane board without losing his or her balance or overrunning the board. In this position, the rail device allows the hydroplane board to spin when the user is on-board without the board digging into the sand on one side, which could interrupt the ride. - Referring to
FIG. 10 , a cliff-shapedspeed rail 14 b gradually slopes upwardly to the apex 23 on one side. The sloped rail accommodates the heel of the user when the hydroplane board withrail device 40 is in use. From the apex 23, thespeed rail 14 b abruptly slopes downwardly at approximately a ninety (90) degree angle. Thespeed rail 14 b is generally convex between the topside railinner edge 21 and the apex 23, and generally concave between the apex 23 and the topside railouter edge 24. - Referring to
FIG. 11 , aspeed rail 14 c gradually slopes upwardly from the topside railinner edge 21 to the apex 23, and then gradually slopes downwardly to the topside railouter edge 24. This provides additional surface area with the board for maximum adhesion. Thespeed rail 14 c generally has a constant slope between the topside railinner edge 21 and the apex 23, and the apex 23 and the topside railouter edge 24. -
FIG. 12 illustrates aspeed rail 14 d that gradually slopes upwardly to the apex 23. From the apex 23, thespeed rail 14 d gradually slopes downwardly then abruptly slopes downwardly such that the topside railouter edge 24 meets thetop side 11 b at about a ninety (90) degree angle. Thespeed rail 14 d generally has a constant slope between the topside railinner edge 21, and is generally concave between the apex 23 and the topside railouter edge 24. The topside railinner edge 21 meets the top side at an obtuse angle. - Of course, other variations in the shape of the
speed rail inner edge 21 and the apex 23, thespeed rail outer edge 24, thespeed rail inner edge 21 may meet thetop side 11 b at an acute, obtuse, or about ninety (90) degree angle. The topside railouter edge 24 may meet thetop side 11 b at an acute, obtuse, or approximately a ninety (90) degree angle. Thespeed rail top side 11 b to the apex 23 and then falls to encounter thetop side 11 b. - In regard to the hydroplane board itself, the
bottom side 11 a of thehydroplane board 10 has a first diameter that is smaller than a second diameter of thetop side 11 b. The first diameter of thecircular hydroplane board 10 should suit the size and ability of the user. The second diameter (top side of the hydroplane board) is preferably about one to two inches less than the first diameter. Although the bottom edge of the hydroplane board preferably is tapered, thetop side 11 b of thehydroplane board 10 is preferably not tapered. Smoothly tapered lower side rails 31 connect thebottom side 11 a of the board to thetop side 11 b. Thebottom side 11 a of the hydroplane board has a co-efficient of friction between a hydroplaning surface, such as sand, and a layer of water over the hydroplaning surface that is lower than a co-efficient of friction between thetop side 11 b and the user's feet. Thebottom side 11 a of the board is coated with marine varnish or polyurethane. Preferred embodiments of thehydroplane board 10 have a bottom side diameter of between about one and about two inches less than the top side diameter, and a thickness of about half the difference between the bottom side and top side diameters. - The
hydroplane board 10 is not intended to be towed behind a boat or the like, so thehydroplane board 10 does not comprise a towing means, seating means, or steering means. Rather, thehydroplane board 10 is utilized for personal skim boarding, or hydroplaning, along an edge of a body of water, such as the ocean or lake shore. The hydroplane board is not intended for surfing, and preferably does not include a skeg or any other attachment to the bottom side of the hydroplane board. The bottom side of the instant hydroplane board is smooth so that it skims along on the water. - The speed rail assists the user in mounting the
hydroplane board 10 by providing a visual guide. The user spots the speed rail while he/she is running alongside the moving board, and attempts to place his/her feet directly in front of the speed rail for best operation. - Alternatively, the present invention is a topside device, such as a
speed rail 14 and/or acircular bumper 13, for attachment to an existingcircular hydroplane board 10. Thetopside device 30 comprises: -
- 1) a curved,
flexible speed rail 14 attachable to the top side of thehydroplane board 10, so that it extends upwardly from the top side of the hydroplane board and is substantially parallel to at least a portion of an outer edge of the circular-shaped hydroplane board, as described hereinabove (seeFIGS. 4-7 ), the speed rail comprising a substantially flat bottom, an arched top, and at least one tapered side, as seen inFIGS. 6 and 9 ; and/or - 2) a
malleable bumper 13 attachable to the outer edge of thehydroplane board 10, thebumper 13 comprising a rounded top 17, a taperedinside edge 15 and a roundedouter edge 19, a portion of the bottom (see 35) of the bumper being substantially planar (seeFIGS. 1, 4 , and 16). Thebumper 13 preferably extends beyond the outer edge of thehydroplane board 10, as shown inFIGS. 7 and 8 , to protect the edge of the hydroplane board. At least a portion of the bumper is attachable to the top side of the hydroplane board adjacent to thespeed rail 14.
- 1) a curved,
- The
speed rail 14 directs the forward force vector entirely into thehydroplane board 10 like thetopside device 20, thus allowing for an increase in instantaneous velocity or mass of the user. Also like thetopside device 20, thebumper 13 shields any innocent bystanders from the relatively sharp,outer edge 12 of the movinghydroplane board 10. It lessens impact between the movinghydroplane board 10 and any stationary or moving object. - In order to utilize the
hydroplane board 10 with thetopside device hydroplane board 10 in the shallow water on the beach; pushes the hydroplane board forward; jogs or runs towards thehydroplane board 10; and jumps onto thehydroplane board 10. The user may continually dismount and remount the hydroplane board while hydroplaning along the water's edge. The user may dismount thehydroplane board 10 when it slows; push and accelerate thehydroplane board 10 in a direction opposite to the dismount while he/she is dismounting; remount thehydroplane board 10; and the user may repeat these steps to continually dismount and remount while hydroplaning. Also, the user may further spin thehydroplane board 10 in the shallow water, holding thehydroplane board 10 in place in the water with centripetal force, then pushing the hydroplane board forward. The user may spin thehydroplane board 10 with his or her foot. The topside device of the present invention facilitates these movements. - Referring to
FIG. 13 , thespeed rail 29 may be curved as shown inFIG. 13 , rather than ring-shaped as shown attached to ahydroplane board 10 inFIG. 4 . Advantages of acurved speed rail 29 include the following: -
- 1) The
curved speed rail 29 serves as a visual aid to show the user where to place his or her feet during the mount;
It facilitates mounting the hydroplane board when the board is moving, since half the board is free of any speed rail; - 2) It makes an interesting, circular visual pattern when the user spins the hydroplane board, particularly when the speed rail is brightly colored or swirled; and
- 3) When the rail is to the side, the curved speed rail facilitates radial motion and forward motion.
Thecurved speed rail 29 has a curved topside railinner edge 21 concentric to its curved topside railouter edge 24. The topside railouter edge 24 is adjacent to theinner bumper edge 15. Theouter bumper edge 19 extends beyond and protects theouter edge 12 of thehydroplane board 12. The ends 33 of thecurved speed rail 29 are tapered to meet the surface of the hydroplane board.
- 1) The
- Referring to
FIG. 14 , the bumper may be segmented as shown inFIG. 14 , rather than ring-shaped as shown inFIG. 1 . Although fourbumper segments 34 are depicted inFIG. 14 , there may be more or fewer bumper segments. Theouter edge 12 of the hydroplane board is visible between thebumper segments 34. Thebumper segments 34 are attachable to the hydroplane board by peeling a paper tape from an adhesive area 35 a on the bottom of eachbumper segment 34, or by any other suitable means. Alternatively, thebumper segments 34 may be applied to theboard 10 by applying a waterproof adhesive to the edges of the bumper segment and clasping it around theouter board edge 12, or by any other suitable means. Advantages of asegmented bumper 34 include the following: -
- 1) Little bumper material is used;
- 2) A segmented
bumper 34 works as well as acircular bumper 13, as long as the gaps between the bumper segments are not longer than the bumper segments; and - 3)
Bumper segments 34 are easy to install on an existing circular hydroplane board. Aspeed rail bumper segments 34 or abumper 13. The speed rail may also be comprised of a number ofrail segments 29 b (seeFIG. 17 ).
- Referring to
FIGS. 15 and 16 , a combinedtopside device 20 comprises aspeed rail portion 14 a andbumper portion 13 a, which are described hereinabove. Thespeed rail portion 14 a extends around the inner side of thebumper portion 13 a. The combinedtopside device 20 is attachable to a circular hydroplane board as depicted inFIGS. 1 and 3 . The combinedtopside device 20 is attachable to acircular hydroplane board 10 by applying a waterproof adhesive to the edges of the combined topside device and pressing it against the outer edge of the hydroplane board, by peeling a paper tape off anadhesive area 35 on the bottom of thetopside device 20, as shown inFIG. 16 , or by any other suitable means. - Continuing with
FIGS. 15 and 16 , thebumper portion 13 a of the combinedtopside device 20 acts as a shock absorber and cushions any impact that occurs between thehydroplane board 10 and another person or inanimate object, such as a rock, a piling, or driftwood lying on a beach. Thebumper portion 13 a cushions the relatively sharp,outer edge 12 of the hydroplane board, so the edge is less likely to chip or crack when the board strikes a hard object. If thehydroplane board 10 with its bumper collides with a person, the wide, rounded, soft bumper hits the person rather than the relatively sharp,outer edge 12 of the hydroplane board. Thetopside device 20 prevents injuries. Thespeed rail portion 14 a provides the user with an angled foothold for comfortable and secure landings and enhanced control of the hydroplane board. It allows the user to jump onto the moving hydroplane board without losing his or her balance or overrunning the moving board. - The
speed rail 14 is substantially parallel to at least a portion of an outer edge of the circular-shaped hydroplane board, as shown inFIG. 4 . Thespeed rail 14 is preferably ring-shaped and of a size sufficient to generally encircle a center of the top side of thehydroplane board 10, as shown inFIG. 4 . Preferably, the two opposite sides of the speed rail are tapered to meet the board, as shown inFIGS. 6, 9 and 11 (at 21 and 24). Where both are employed on a board, thespeed rail 14 is parallel to thebumper 13, and thespeed rail 14 and thebumper 13 are both ring-shaped, a diameter of the speed rail being smaller than a diameter of the bumper. The two are preferably made of a flexible waterproof material such as a natural or synthetic rubber. - In an alternate embodiment, the bumper is a plurality of
bumper segments 34, as shown inFIG. 14 , each of thebumper segments 34 being attachable to thehydroplane board 10. The bottom of thebumper segments 34 preferably comprises a waterproof adhesive, so a user can press the bumper segments onto his or her board. Preferably three to sixmatching segments 34 are employed, with the distance between the segments not exceeding the length of the segments. - Turning to
FIG. 17 , the speed rail may be comprised of a number ofrail segments 29 b, preferably three to fivesegments 29 b. Each of the rail segments is attachable to thehydroplane board 10. The bottom of therail segments 29 b preferably comprises a waterproof adhesive, so a user can press the rail segments onto his or her board, preferably forming a curved shape on the board, as shown inFIG. 17 . - From the foregoing it can be realized that the described device of the present invention may be easily and conveniently utilized as a hydroplane board topside device for directing forces into the circular hydroplane board of the invention, and/or absorbing forces encountered by the circular hydroplane board. It is to be understood that any dimensions given herein are illustrative, and are not meant to be limiting.
- While preferred embodiments of the invention have been described using specific terms, this description is for illustrative purposes only. It will be apparent to those of ordinary skill in the art that various modifications, substitutions, omissions, and changes may be made without departing from the spirit or scope of the invention, and that such are intended to be within the scope of the present invention as defined by the following claims. It is intended that the doctrine of equivalents be relied upon to determine the fair scope of these claims in connection with any other person's product which fall outside the literal wording of these claims, but which in reality do not materially depart from this invention. Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
