20230036601
This present application claims priority to U.S Provisional Application No. filed Jul. 16, 2021 and entitled “FOLDABLE WATER FLOW DEFLECTION DEVICE AND METHODS OF USE” which is hereby incorporated by reference in its entirety.
The present invention relates generally to watercraft accessories and wake shaping, in particular a water flow deflection device for a watercraft that can form a desirable wake, even more particularly a water flow deflector of the device having at least one portion moveable between an extended position and a folded position, such that the extended position enhances the surface area of the water flow deflector and the folded position facilitates storage of the device.
The sport of wake surfing, performing surfing maneuvers on a surfboard in the wake of a boat without using a tow rope, has become popular among water sports and boating enthusiasts. Wake surfing is similar to surfing on natural ocean waves, except it is performed on the waves formed behind a moving boat. However, wake surfing is limited to boats capable of providing good surfable waves at a safe distance behind the boat. Wake surfing requires a large wake pattern to enable the rider to perform surfing maneuvers. New boats have been equipped with various systems to generate the surfable wake. However, the creation of sufficiently large, steep, surfable quality waves using older conventional ski boats is difficult and potentially dangerous for the wake surfer, the boat, and passengers.
Conventional water ski boats are not designed to make waves but, rather, to minimize them in order to minimize power requirements and to provide the smooth wake patterns that high speed skiing requires. Thus, the goal of conventional ski boat designs are to lessen displacement, decrease drag, and enable the boat to travel faster with less energy.
In order to generate an increase in wake size, wakeboarders have attempted to overcome the design objectives of conventional water ski boats by adding heavy, static ballast to the boat. Such ballast is usually in the form of water filled bags, concrete blocks, or other such weighted objects that disadvantageously occupy inboard passenger space. One other significant disadvantage to static ballast is that it can easily lead to an unsafe overload condition for the boat and passengers.
Ballasted boats for wakeboarding will not necessarily create wakes with surfable quality at normal speeds. Therefore, creating a surfable wave with a conventional ski boat typically involves a reduction in speed to less than 15 mph along with the addition of ballast to the boat. At such speeds and weights, the waves created by the boat are typically within a few feet of the boat's transom, as well as the exhaust and propeller. This makes wake surfing using conventional ski boats difficult to perform, unhealthy, and potentially dangerous.
Thus, there is a need in the art for aftermarket adaptability of boats for wake surfing. There is a further need in the art for adjustability in aftermarket devices to provide maximum wake with minimal boat modification. There is a further need in the art to maximize the hydrodynamics of such aftermarket devices while minimizing the space of such aftermarket devices onboard a boat when the device is not being utilized.

The above summary is not intended to describe each illustrated embodiment or every implementation of the subject matter hereof. The figures and the detailed description that follow more particularly exemplify various embodiments.
Subject matter hereof may be more completely understood in consideration of the following detailed description of various embodiments in connection with the accompanying figures, in which:
While various embodiments are amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the claimed inventions to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the subject matter as defined by the claims.
The present application is directed to a water flow deflection device 100 configured to be attached to a side 102 of a watercraft 104 for wake enhancement. The water flow deflection device 100 can be attached to either side of the watercraft 104 to divert oncoming water as the watercraft 104 is moving forward. A water flow deflector 112 on the device 100 can be adjusted from a stored position to an operating position, such as a fully extended position or an intermediate position between the fully extended position and the stored position, to create the desired wake. The water flow deflector 112 may optionally be adjusted to a desired surface area size and/or desired angular position relative to the watercraft to further adjust the created wake.
Referring now to the figures,
Referring now generally to
The extension arm 118 extends away from the base 116 in an approximately 90 degree angle. While the angle that the extension arm 118 extends away from the base 116 is illustrated as approximately 90 degrees, the extension arm 118 may also be positioned at different angular orientations relative to the base 116. A top portion of the extension arm 118 in proximity to the second end 128 may be bent at an angle relative to a remainder of the arm 118. This configuration provides a surface for supporting the deflector 112 as will be explained below.
The extension arm 118 and base 116 may be constructed from a variety of different material, including but not limited to High-density polyethylene (HDPE) and Low-density polyethylene (LDPE). The base 116 and arm 118 may be constructed from the same or different materials. In one embodiment, the arms 116, 118 are constructed from a buoyant material that causes the water flow deflector device 100 to float when in the water and detached from the boat 104.
One or more suction cups 120 are attached to the base 116 to attach the device 100 to the watercraft 104. Any number of suction cups may be used, as illustrated in the various figures. In certain preferred aspects, the device 100 utilizes two suction cups 120. In certain preferred aspects, a first suction cup 130 is attached to the base 116 proximate to the first end 122, and a second suction cup 132 is attached to the base 116 proximate to the second end 124. The suction cups 120 may be attached to the elongated base 116 in a variety of different manners. For example, the suction cups 120 may be attached using a mechanical fastener such as a screw or bolt, may fit within slots/rails formed along the base 116, or may be integrally formed with the base 116. The suction cups 120 may be equipped with a release lever 131 to selectively secure and remove the suction cups 120 from the side 102 of the boat 104. The suction cups 120 may have various sizes. In some embodiments, the suction cups 120 have a diameter of between 1 and 6 inches to have sufficient suction to hold the water flow deflection device 100 against the side 102 of the boat 104 while the boat is moving through the water.
The water flow deflector 112 is generally attached to the extension arm 118. In certain preferred aspects, the first section 140 of deflector 112 is attached at the second end 128 of extension arm 118 as illustrated in
The deflector 112 includes an enlarged surface area that faces away from the extension arm 118 and is configured to deflect oncoming water during normal operation. The surface area may include a rectangular shape, although other shapes may also be used with each including a length and a width. The deflector 112 includes a first section 140 having a leading end 136 and a second section 141 having a trailing end 138 opposing the leading end 136. As illustrated in
In some preferred aspects, the first section 140 of deflector 112 is operable attached to the second section 141 by one or more hinges 170. In certain preferred aspects, the first section 140 has a distal end that operably engages with a proximate end of the second section 141 to form one or more integral hinges 170 having one or more rods running through a longitudinal axis of each integral hinge 170. In some alternative aspects, a hinge 170 is proximately located on the backside of the deflector 112, whereby the hinge is attached to the first and second sections 140, 141 in various manners including but not limited to welding and mechanical fasteners.
The one or more hinges 170 allow the second section 141 to rotatably swivel with respect to the first section 140 in a folding mechanism. The folding mechanism of deflector 112 allows the device 100 to be folded, such that the overall size of the device 100 can have a smaller configuration for storage when not being used, as storage space on a watercraft 102 can be a premium.
In certain preferred aspects, the second section 141 is foldable with respect to the first section 140, such that the deflector 112 is capable of being rotatably adjusted between a fully extended position and a folded position. As shown in
In some aspects, deflector 112 is adjusted to the fully extended position during normal operation, such that deflector 112 in the fully extended position operably engages with oncoming water to enhance the water flow deflection 100 as watercraft 104 moves through the water and thereby enhancement of wake formation behind watercraft 104. In some aspects, deflector 112 is adjusted to the folded position for storage, such as when the device 100 is removed from the side 102 of watercraft 104.
Deflector 112 is also capable of being positioned at an intermediate position along angle D during normal operation, whereby the second section 141 is adjusted to a position between the fully extended position and the folded the position. For instance, as shown in
In certain preferably aspects, second section 141 can be locked into the fully extended, an intermediate position, or the folded position with respect to first section 140. In some aspects, a fastening means can lock second section 141 into the desired position with respect to first section 140.
In certain preferred aspects, the fastening means is a quick release skewer assembly 182, as shown in
The fastening means can also comprise one or more bars 190 proximately located the backside of deflector 112, the one or more bars 190 slidable between a locked position and an unlocked position. In the locked position, bars 190 extend above first section 140 to operable engage with second section 141 and preventing second section 141 from rotatably swiveling along the longitudinal axis of hinge 170, such that second section 141 is incapable of folding during normal operation when oncoming water operably engages deflector 112. In the unlocked position, second section 141 is capable of rotatably swiveling along the longitudinal axis of hinge 170 and being rotated to the folded position. Second section 141 can be locked into the folded position.
In some preferred aspects, second section 141 is about 50% or less of the total surface area of deflector 112, such that first section 140 is about 50% or greater of the total surface area of deflector 112. In some aspects, second section 141 is between about 10% and about 50% and first section is between about 50% and 90% of the total surface area of deflector 112 in the fully extended position.
Besides deflector 112 being capable of being folded, deflector 112 can also have an adjustable extension to provide the desired surface area of deflector 112 for wake shaping. As illustrated in both
In one embodiment, one or more fasteners 119 fixedly attach first section 140 to the extension arm 118. Extendible section 142 is then movably attached to second section 141 of the deflector 112. In one embodiment, as shown in
In the embodiment of
In certain preferred aspects, first section 140 of deflector 112 may be fixedly attached to the extension arm 118. This provides for the foldable second section 141 to be rotatably adjusted between the fully extended position and any intermediate position up to the folded position. This also provides extendible section 142 of deflector 112 to be moveable in front of and supported by second section 141. This provides additional support for the extendible section 142 when the device 100 is in use and be acted upon by the water. The force of the water acting on the extendible section 142 maintains its position against the back second section 141.
The size of the deflector 112 is adjustable not only on the folded position of second section 141 with respect to first section 141 but also based on the relative positioning of the extendible section 141 with respect to second section 141. The overall size of the deflector 112 is formed by the amount of exposed area of each of the sections 140, 141, 142. The deflector 112 will have the largest surface area when second section 141 is in the fully extended position with respect to first section 140 and extendible section 142 has the least overlap with second section 141 and are slid apart. Likewise, deflector 112 will the smallest surface area when second section 141 is in the fully folded position with respect to first section 140 and extendible section 142 has enough overlap with second section 141 and are slid together such that second section 141 and extendible section 142 do not operably engage with oncoming water when the watercraft 104 is going through the water, but only first section 141 operably engages with oncoming water. Accordingly, the amount of surface area of deflector 112 can be adjusted to various different surface areas, with the desired surface area for wake shaping being adjusted based upon the folded position of second section 141 and the extended position of extendible section 142.
In one embodiment, second section 141 and extendible section 142 are adjustable along one dimension. As shown in
The deflector 112 may also be configured to provide for adjustment along two dimensions, such as to adjust a length and a width.
As illustrated in
Second section 141 and extendible section 142 may include the same shapes and sizes. For example, the embodiment of
The angle α of the deflector 112 relative to the base 116 can also be adjustable. As illustrated in
The support 114 is connected to the same section of the deflector as the extension arm 118. In one embodiment as illustrated in
The support 114 may be a threaded member such as a bolt with one or more adjustable securing members 148. The securing members 148 may be configured to allow a user to hand tighten or loosen the member 148 to adjust the angle α. In one embodiment, the securing members 148 may be wing nuts, knobs, or bolts. The securing member 148 may be configured so as to be affixed on one or both sides of the extension arm 118. For example, in some embodiments only one securing member 148 may be required in order to provide for adjustment, while other embodiments as illustrated in
The water flow deflection device 100 may be configured such that it is buoyant, causing the water flow deflection device 100 to float in water when detached from the watercraft 104. The buoyancy may be a result of one or more sections of the frame 110 being hollow. The water flow deflection device 100 may also be configured with a leash that is attachable to the watercraft 104.
In an alternative configuration as illustrated in
A method of use of the water flow deflection device 100 is illustrated in
Some of the adjustments may occur prior to attachment to the boat. Alternatively, some or all of the adjustments may occur after the device is attached to the boat.
