ATTACHABLE-AND-RELEASEABLE (SWAPPABLE) FIN FOR SPORT BOARD, AND ADJUSTABLE MAST FOR FOILING SYSTEMS
An embodiment of a mast includes a first support configured for coupling to one of a foiling platform and a foiling assembly, and a second support configured for coupling to the other of the foiling platform and the foiling assembly and for coupling to the first support in a manner that allows adjustment of a combined height of the first and second supports. For example, such a mast can be configured to have first and second telescoping supports that can be extended and retracted to different heights so that surfers of different skill levels can use the same mast.
This application is a continuation which claims the benefit of 63/348,940 filed Jun. 3, 2022 which is incorporated by reference as if fully set forth.
BACKGROUNDSport boards, such as water boards including wake boards, foil boards, surf boards, and paddle boards, are used for recreation and entertainment. For example, water boards are typically used in bodies of water such as a pond, lake, or river (e.g., wake boards, foil boards, and paddle boards) or the ocean (e.g., surf boards).
A water board may include one or more fins that improve the velocity, stability, maneuverability, and/or other operational characteristics of the water board. For example, a surf board may have a single, large fin at the trailing (back) end of the board, and a wake board may have a single fin, or dual fins, in the middle of the board.
Attachable and replaceable, i.e., swappable, fins on, for example, wake boards allow one to swap out the fins so that multiple people of different skill levels and boarding preferences can use the same board but configured for an appropriate skill level.
But removing and/or installing such a fin can be cumbersome.
For example, such a fin may require a tool, such as an Allen Wrench or a Torx Wrench, for installation and removal. Unfortunately, such tools are often cumbersome to transport and/or to keep in a “handy” location on a boat or otherwise, and/or one can lose such a tool in the normal course of use and/or storage, for example, by dropping the tool in the water while installing and/or removing a fin on a boat or otherwise on or near the water (e.g., on a dock).
Another type of fin that is designed to allow installation and removal “by hand” still may require the use of one or more tools for installation or removal. In an example, a fin is intended to “snap” into a receiving slot disposed in a wake board and including springs that the manufacturer designed to hold the fin in place. But the force that one must exert to overcome the force generated by the springs can be too large for him/her to remove and/or install the fin without the use of a tool. For example, if such a fin follows the trend of wake-board fins being made shorter and sharper, it may become more difficult for one to grasp such a fin and to generate the force needed to install and/or to remove, toollessly, the fin without cutting himself/herself on a sharp fin edge.
And the design of such a fin and a corresponding fin receiving slot on a board can cause the fin to loosen eventually, and/or to be loose, during normal use of the board. For example, over time such a fin may loosen from a fin mount in a wake board in response to the fin propagating through the water or bumping into one or more other objects such as the deck of a boat. And a loose fin may negatively affect the way a wake board handles by vibrating as the fin, along with the wake board, propagates through the water, and/or even may “fall out” of the board into the water and be irretrievably lost, particularly if the fin does not float.
Other types of sport boards include masts.
For example, a foiling system includes a foiling assembly configured to propagate through water, a platform or board configured to support a user (called a “foiler”), and a mast configured to be supported by the foiling assembly and to hold the board above the water while the user is foiling.
One end of the mast is attached to the bottom of the board, and the other end is attached to the foiling assembly, which propagates through the water during foiling and which includes a fuselage, a wing at a leading end of the fuselage, and a stabilizer at a trailing end of the fuselage.
The mast is typically sold separately, and comes in a number of different lengths (heights), for example 14″, 17″, 20″, 24″, 28″, and 30″, where more-experienced foilers typically prefer a taller mast, and less-experienced foilers typically prefer a shorter mast. For example, a taller mast typically can provide a more exciting ride by allowing a foiler to generate more momentum and motion when “pumping” to move. But a taller mask typically makes foiling more difficult for a beginner.
Consequently, groups of foilers, such as families, that use a same foiling board but that each have a different skill level typically acquire multiple different-height masts that they swap out between uses of the board by different foilers.
But swapping out masts can be expensive because each mast is relatively expensive (e.g., US$1000-US$7500).
Furthermore, the weight of a mast, and that a mast is typically non-buoyant, typically make swapping out a mast even more difficult while on a boat, at the dock, and/or otherwise on the water. For example, a mast may be too heavy for a child to swap out, or one may drop the mast in the water, causing the mast to irretrievably sink.
A conventional mast typically is relatively heavy and non-buoyant because the mast is designed to be relatively rigid to reduce the energy that a rider exerts while foiling. For example, a conventional mast is rigid (for example, solid and made from a metal such as aluminum) such that when a foiler applies a force to the board with his/her body to cause the foil board to move, the force that the user applies contributes mostly to the motion of the foil board and not to the deformation of the mast (for example, due to slight back-and-forth bending of the mast). That is, conventional masts are made to be rigid to minimize mast deformation, and, therefore, to minimize the amount of rider energy that the mast absorbs.
But to make a conventional mast sufficiently rigid to reduce or eliminate mast deformation in response to the foiler's motion and, therefore, to reduce or eliminate the amount of the foiler's motive energy that the mast absorbs, a conventional mast is typically made from a metal and is solid.
Unfortunately, a solid metal mast is relatively heavy, and a heavy mast can cause one or more problems. For example, a heavy mast can be cumbersome to handle, more difficult to swap out, and can make the assembled foiling-board system heavier to carry. Furthermore, due to its greater mass, a solid metal mast can render a foil-board system more difficult to maneuver because it has a slower response time; that is, the greater mass of a solid metal mast can render a foil-board system less responsive than a lighter mast. But to make a conventional mast lighter, one typically makes the mast less rigid, so there is typically a tradeoff between the mass and rigidity of a conventional mast, with many mast manufacturers sacrificing lower mass for greater rigidity.
And a conventional mast, particularly a solid metal mast, is relatively expensive (e.g., in the hundreds to thousands of dollars per mast), making foiling a relatively expensive hobby, particularly for families or other groups of foil boarders that purchase multiple masts having different heights to accommodate the different skill levels of the groups' members as described above.
SUMMARYA need has arisen for a sport-board fin that is installable and removable (swappable) without the use of tools.
For example, such a need can be met by a fin having a blade and a base configured for toolless installation within, and toolless removal from, a fin receptacle of a water board. For example, such a fin and fin receptacle can be configured such that the receptacle holds the fin (e.g., a fin of a wake board) firmly and stably when the fin is installed in the board, but also allows toolless removal of the fin.
A need also has arisen for a foil-board-system mast that has an adjustable height (length) and is lighter (has a smaller mass) than conventional foil-board-system masts.
For example, such a need can be met by a mast having a first support configured for coupling to one of a foiling platform and a foiling assembly, and a second support configured for coupling to the other of the foiling platform and the foiling assembly and for coupling to the first support in a manner that allows adjustment of a combined height of the first and second supports. For example, such a mast can be configured to have first and second telescoping supports that can be extended and retracted to different heights so that surfers of different skill levels can use the same mast, and one or more of the supports can be hollow (instead of solid) to lessen the mass of the mast, with little to no reduction in the rigidity of the mast, as compared to a conventional mast. And the mast height can be adjusted even while the mast is attached to a foiling platform and/or to a foiling assembly and while the foiling system is in a place of use, such as on a boat or dock.

The fin 1006 includes a blade 3002 and a base 3004 having posts 3006 and 3008—the hole in each of the posts are for engage tooling during manufacturing of the fin, and may reduce the amount of material needed to form each post without reducing the robustness of the post, but typically serve no function after the fin is formed. The blade 3002 includes a leading edge 3003 and a trailing edge 3005 and is configured to have conventional fluid-dynamic properties for moving through, for example, water, and the base 3004 and posts 3006 and 3008 are configured to engage the attach-and-release mechanism 1004 and to allow this mechanism to stably and securely hold the fin 1006 while a rider (e.g., a wake boarder) is using the board system 1000 of
In addition to the housing 2000, the mechanism 1004 includes a pivot pin 3010, hinge-lock levers 3012 and 3014, a spring 3016, and a button 3018 configured for disposal in the cavity 2002 of the housing. The housing 2000 has two halves, 3020 and 3022, which each include a respective pivot-pin receptacle 3024 and 3026 each configured to receive and to hold in place a respective end of the pivot pin 3010. The hinge-lock levers 3012 and 3014 each include a respective opening 3028 and 3030 configured to slide over respective ends of the pivot pin 3010 before the ends of the pivot pin are inserted into the receptacles 3024 and 3026, and are configured so that when installed in the mechanism 1004, the openings are aligned with each other. The hinge-lock levers 3012 and 3014 also include spring arms 3032 and 3034 (
Referring to
First, one holds the fin 1006 by the blade 3002 such that the posts 3006 and 3008 are aligned with the slots 3036 and 3038, respectively.
Next, one moves the posts 3006 and 3008 toward, and then into, the slots 3036 and 3038, respectively.
As the posts 3006 and 3008 move further into the slots 3036 and 3038, bottom ends 5000 and 5002 of the posts contact the hinge-lock levers 3012 and 3014, respectively.
As the posts 3006 and 3008 move even further into the slots 3036 and 3038, the bottom ends 5000 and 5002 push the hinge-lock levers 3012 and 3014 toward each other, further compressing the spring 3016. That is, the bottom end 5000 causes the hinge-lock lever 3012 to rotate about the pivot pin 3010 in a counterclockwise direction, and the bottom end 5002 causes the hinge-lock lever 3014 to rotate about the pivot pin in a clockwise direction.
As the posts 3006 and 3008 move still further into the slots 3036 and 3038, the bottom ends 5000 and 5002 move past the ends of the hinge-lock levers 3012 and 3014, respectively, which allows the spring 3016 to decompress and rotate the levers 3012 and 3014 in the clockwise and counterclockwise directions, respectively.
This rotation of the hinge-lock levers 3012 and 3014 causes the ends of these levers to slip past the post bottom ends 5000 and 5002 and engage notches 5004 and 5006 in the posts 3006 and 3008, respectively.
Furthermore, the detents 3007 and 3009 engage the protrusions 3048 and 3050, respectively.
Consequently, the posts 3006 and 3008 are locked into the slots 3036 and 3038, respectively.
If one attempts to pull the fin 1006 out of the attach-and-release mechanism 1004 without pushing the button 3018, the post bottom ends 5000 and 5002 cause the hinge-lock levers 3012 and 3014 to rotate in the clockwise and counterclockwise directions, respectively, such that the horizontal (in
To release the fin 1006 from the attach-and-release mechanism 1004, one pushes down (in a direction toward the cavity 2002) on the button 3018 such that bottoms of slot walls 3060 and 3062 (
After the fin 1006 is removed from the attach-and-release mechanism 1004 such that the posts 3006 and 3008 are fully removed from the slots 3036 and 3038, respectively, and one release the button 3018, the spring 3016 decompresses and pushes the hinge-lock levers 3012 and 3014 in clockwise and counterclockwise directions, respectively, about the pivot pin 3010. The ends of the levers 3012 and 3014 press against the bottoms of the slot walls 3060 and 3062, thus forcing the button 3018 toward the top of the cavity 2002. But the housing overhang 3046 engages the button lip 3044, thus preventing the hinge-lock levers 3012 and 3014 from pushing the button 3018 out of the cavity 2002; that is, the housing overhang engages the button lip to resist the upward force that the hinge-lock levers exert on the button so that the button does not “pop out” of the housing cavity 2002.

The fin 7000 includes a blade 7004, a leading edge 7006 and a trailing edge 7008, and a base 7010 with two posts 7012 and 7014 each having a protrusion 7016 and 7018. And the leading-edge post 7012 includes a notch (here a rectangular or square notch) 7020.
The attach-and-release mechanism 7002 includes a housing 7022 having a leading end 7024 and a trailing end 7026, a button assembly 7028 having a button outer shell 7030 and a button inner shell 7032, and a spring 7034.
The housing 7022 includes a cavity 7036 for receiving and holding the button assembly 7028 and the spring 7034 and includes slots 7038 and 7040 configured to receive the fin posts 7012 and 7014, respectively. The housing 7022 also includes openings 7042 and 7044 in the wall of the cavity 7036.
The button outer shell 7030 includes a slot 7046 and opening 7047 (and includes another opening opposite the opening 7047 but not visible in

In response to disengagement of the protrusion 7054 by the post slot 7020, the force generated by the spring 7034 causes the button inner shell 7032, the button outer shell 7030, and the protrusion 7054 to move upward toward the top of the cavity 7036 until the top of the button outer shell 7030 contacts an underside 12000 of the fin blade 7004.
In this position, the fin 7000 is latched, or locked, into the attach-and-release mechanism 7002. The protrusions 7016 and 7018 contact the tops of the receptacles 9000 and 9002, respectively, and, therefore, prohibit the spring 7034 from pushing the fin 7000 out of the slots 7038 and 7040. Furthermore, a trailing edge 12002 of the protrusion 7054 contacts a leading edge 12004 of the post 7012, thus holding, stably, the post such that the protrusions 7016 and 7018 remain in, and cannot back out of, the receptacles 9000 and 9002. That is, in this latched or locked state, the attach-and-release mechanism 7002 can hold the fin 7000 such that the fin does not fall out, and cannot be pulled out (without pushing the button 7028), of the attach-and-release mechanism, and also such that the fin exhibits little or no “wiggling” during use or even when one attempts to wiggle the fin.
Referring to
He/she then slides the fin 7000 toward the leading edge 7024 of the attach-and-release mechanism 7002 such that the post slot 7020 engages the protrusion 7054.
Next, he/she gently releases the button 7028 while still holding the fin 7000, and the spring 7034 decompresses to force the button toward the top of the cavity 7036 and the posts 7012 and 7014 toward the tops of the respective slots 7038 and 7040.
Then, when the button 7028 is fully released, he/she can pull the fin 7000 such that the posts 7012 and 7014 fully disengage (come out of) the slots 7038 and 7040.
To retain the button 7028 within the cavity 7036 after the fin 7000 is removed from the attach-and-release mechanism 7002, the housing 7022 and the button outer shell 7030 can include a retaining overhang and a lip, respectively, that are the same as, or are similar to, the retaining overhang 3046 and the lip 3044 of

The fin 13000 includes a blade 13004, a leading edge 13006, a trailing edge 13008, posts 13010 and 13012, and a spring tab 13014.
And the attach-and-release mechanism 13002 includes a housing 13016 having a cavity 13018 and a notch 13020. The housing 13016 can be attached to the sport board 1002 of
Although the spring tab 13014 is described as being in the middle of the fin 13000 between the two posts 13010 and 13012, the spring tab can be disposed in any location along a bottom of the fin relative to one or more posts. Furthermore, there can be more than one spring tab 13014 and more or fewer than two posts 13010 and 13012. For example, the tab 13014 can be positioned at one edge of the fin 13000 adjacent to a single post that can be larger than either of the posts 13010 and 13012, for example, configured to fill the remainder of the cavity 13018 (to fill the portion of the cavity not occupied by the spring tab).

As the posts 13010 and 13012 slide farther into the cavity 13018, the spring-tab protrusion 14002 enters the cavity such that the inner wall of the cavity effectively pushes the spring tab 13014 inward.
As the posts 13010 and 13012 slide even farther into the cavity 13018, eventually the protrusion 14002 becomes aligned with the notch 13020, at which time the spring-action of the spring tab 13014 forces (i.e., “snaps”) the protrusion into the notch.

In addition to the adjustable mast 17002, the foiling system 17000 incudes a foil platform or board 17004 attached directly or indirectly to a top flange 17006 of the adjustable mast, and a foil assembly 17008, which includes a fuselage 17010 attached to a bottom 17012 of the mast, a wing 17014 attached to, or near, a leading edge 17016 of the fuselage, and a stabilizer 17018 attached to, or near, a trailing edge 17020 of the fuselage.
In operation, a payload (e.g., a person called a “foiler”) rides on top of the board 17004, and, as the foil assembly 17008 moves through water, the cross-sectional contour of the wing 17014 generates, in the water under the wing, a force (sometimes called “lift” or a “lifting force”) that lifts the wing, and therefore, lifts the rest of the foiling system 17000, upward such that the board rises out of the water. Because the board 17004 is not contacting the water while the system 17000 and the foiler are moving, the friction and/or resistance that the system experiences is significantly less than if the board were contacting the water, and, therefore, moving the system at a given velocity (e.g., by towing the system and the foiler with a boat, by the foiler “pumping,” by waves, and/or by a boat wake) requires significantly less energy than if the board were contacting the water.
The length, or height, of the mast 17002 is adjustable so that one can adjust the distance, or height, between the foil assembly 17008 (e.g., the fuselage 17010) and the board 17004. This allows one to adjust the height of the mast 17002, for example, for foilers of different experience levels—generally, foilers with more experience prefer a taller mast, and foilers with less experience prefer a shorter mast. And having an adjustable mast 17002 allows for multiple mast heights without the need to acquire multiple masts of different heights. The mast 17002 can be configured such that one can adjust the mast to any one of multiple heights. For example, popular mast heights to which one can adjust the mast 17002 include, but are not limited to, 12″ (inches), 14″, 17″, 20″, 24″, 28″, and 30″, although the mast 17002 can be configured for adjustment to any suitable height.
Furthermore, the mast 17002 can be configured to be lighter than a conventional mast for any given height without significantly sacrificing rigidity of the mast. For example, the mast 17002 can be made from any suitable material, such as a metal (e.g., aluminum), and can include multiple pieces, or supports, that are hollow instead of solid, to reduce the mast weight as compared to a solid mast at a given mast height. The multiple supports can be configured to interconnect with one another in such a way so as to allow adjustment of the mast height. Alternately, a single-piece non-adjustable mast of a given height still can be made lighter than a conventional mast of the same or similar height by making the mast hollow instead of solid.
The mast 17002 has two telescoping supports 18000 and 18002, which are both hollow, and the support 18002 (the male support) is configured to slide within the support 18000 (the female support). The support 18002 includes a nipple 18004 configured for insertion into a receptacle 18006 of the fuselage 17010, and for attachment to the fuselage. For example, the nipple 18004 can be integral with, or attached to a portion of the support 18002 in any suitable manner (e.g., with an adhesive and/or fasteners such as rivets), and the nipple also can be attached to (e.g., with an adhesive and/or fasteners such as screws) the fuselage 17010 in any suitable manner.
The supports 18000 and 18002 each include alignment holes 18010 and 18012, respectively.
To adjust a height h of the mast 17002, one slides the support 18002 within the support 18000 so, that at approximately a desired mast height, at least one of the alignment holes 18010 of the support 18000 is aligned with at least one of the alignment holes 18012 of the support 18002, and then one inserts a first component, such as a screw, of a respective fastener, through each of the aligned pairs of alignment holes and secures each screw with a second component, e.g., a nut or a threaded bushing (

To adjust the height of the mast 17002, one slides the male support 18002 within the female support 18000 until two or more pairs of openings 18010 and 18012 are aligned at the desired mast height. Next, he inserts the threaded bushings 20008 and 20010 into respective ones of the aligned pairs of openings 18010 and 18012. Then, he screws the screws 20004 and 20006 into the bushings with a tool such as a Philip's head screwdriver or by hand (for example, if the screws are thumb screws) until the screws are screwed into the bushings 20008 and 20010. To readjust the height of the mast 17002, one removes the screws 20004 and 20006 from the bushings 20008 and 20010, removes the bushings from the respective aligned pairs of openings 18010 and 10812, slides the male support 18002 inside of the female support 18000 until the mast 17002 is at a desired height, inserts the threaded bushings 20008 and 20010 into respective ones of the aligned pairs of openings 18010 and 18012, and screws the screws 20004 and 20006 into the threaded bushings to secure the mast at the selected height.

The mast 23002 is slanted from the foil assembly 23006 rearward toward a trailing end 23010 of the foiling system 23000. As compared to a straight mast, allowing the mast 23002 to be slanted provides for greater independence in the location 23012 of the mast attachment to the board 23004 relative to the location of the foil assembly 23006 relative to the board. That is, with a straight mast, the location of the foil assembly 23008 would be directly below the location where the straight mast attaches to the board 23004. But with the slanted mast 23002, one can adjust the amount, or angle α, of the slant, as well as the direction (rearward, forward) of the slant, to adjust the location of the foil assembly 23008 relative to the location 23012 where the slanted mast attaches to the board 23004. Adjusting the locations of the mast-board attachment and of the foil assembly 23008 relative to one another can allow a designer to impart, to the foiling system 23000, adjustable properties related to a rider's stance on the board 23002 and mass distribution relative to the foiling system.
Although the mast 23002 is shown as being slanted rearward, the mast can be slanted forward.
And the angle α of the slant can be any suitable angle, for example, in an approximate range of 0°-180°, in an approximate range of 10°-170°, in an approximately range of 45°-135°, etc. And the mast 23002 can be configured to allow adjustment of the angle α.
Furthermore, although the height of the mast 23002 is shown as being non-adjustable, the mast can be an adjustable mast as previously described, for example, in conjunction with
In addition, even where the mast 23002 is non-adjustable, the mast can be hollow (e.g., made from extruded metal such as aluminum) to reduce the mass and weight of the mast as compared to a solid mast as previously described.
Moreover, the location 23012 where the mast 23002 attaches to the board 23004 can be at any suitable position along the board. For example, the location 23012 can be toward or at a front or a front section (leading end) of the board 23004, toward or at a rear or rear section (trailing end) of the board, toward or at a middle or middle section of the board, between a middle or middle section and a rear or rear section of the board, or not between a middle or middle section and a rear or rear section of the board.
In addition to the mast 25002, the foiling system 2500 includes a foiling board 25004 and a foil assembly 25006, which can be similar to any one or more of the foiling boards and foil assemblies, respectively, disclosed elsewhere in this document.
The mast 25002 is mounted to a rail assembly 25008, which can span any suitable length of the board 25004 along an underside (water-facing side) 25010 of the foil board. The rail assembly 25008 is configured to allow one to adjust a location 25012 at which the mast 25002 engages the rail assembly by, for example, attaching the mast to the rail assembly loosely (or loosening an already-tight attachment of the mast to the rail assembly), sliding the mast to a desired location along the rail assembly, and then tightening, by hand or with a tool, a fastener (not visible in
The rail assembly 25008 includes one or more board-attachment structures 25016 (two board-attachment structures shown in
Furthermore, the rail assembly 25008 can include one or more rails 25020 configured for slidable coupling to the plate 25014. For example, the rail assembly 26008 can include two approximately parallel rails.
The foiling board 27002 being slanted relative to the foil assembly 27006 (as compared to being approximately parallel to the foil assembly) can alter characteristics of foiling experienced by a foiler. For example, it may make it easier for a foiler to balance himself/herself on the foiling board 27002 while foiling, for example, while the foiling system 27000 is being towed by a boat or other vehicle.
