- Embodiments disclosed herein relate to attachment methods and devices that utilize locking forces to securely attach a device to an object yet facilitate simple and easy detachability.
- the attachment methods and devices disclosed herein are applicable to a wide range of objects and devices.
- the attachment methods and devices disclosed herein can be advantageously used to couple a device to an object, wherein the device extends vertically from the object when attached, and is likely to encounter horizontal forces when attached to the object.
- the attachment mechanisms disclosed herein can be used to attach a fin to a surfboard or other watercraft, a cleat to a shoe, a wheel truck to a rollerskate, rollerblade, or skateboard deck, a blade to an ice skate, components of components of furniture, or various other device/object pairs.
- spring locking means e.g. canted coiled springs, cantilevered springs, split ring springs, split pin springs, or the like.
- a surfboard is a type of watercraft that is generally longer than it is wide.
- the board generally forms a buoyant deck that a surfer may stand on while surfing. It will be understood, however, that surfboards may also for used for paddling, e.g., while sitting, laying, etc. Additionally, other methods of propulsion may be attached to the surfboard, such as a sail, e.g., for windsurfing.
- Many modern surfboards may be made of polystyrene or polyurethane foam.
- the boards may be covered with one or more layers of fiberglass cloth and a resin such as polyester or epoxy resin.
- Shoe weight and athletic performance are integrally related; the lighter the shoe the less force and thus the less energy is required by the athlete to maneuver. Less weight in the shoe assists the athlete in moving the foot and leg from one position to another more quickly.
- Shoe weight is a well-recognized property by athletes as critical to performance and is understood by shoe manufacturers. Footwear manufacturers describe and advertise shoe weight reductions as a point of comparison in the selling of their shoes against competitors.
- Metal cleats and their corresponding metal threaded inserts can be uncomfortable to the wearer of the shoe particularly over time as the polymers used to make the shoe sole begin to yield to the force of the metal studs. In time, the metal components become more prominent points of pressure between the bottom of the foot and the threaded cleat stud. This is not only uncomfortable, but can be a source of injury to the foot.
- a threaded cleat made from metal or plastic also may significantly limit potential design geometries of the cleat.
- Current cleat designs are constrained to circular cone shaped geometries due to the “threading in” requirement of a screw.
- Alternative geometries in cleat shapes are impractical. Attempting repeatable alignment of the cleat after threading it into the shoe sole is unattainable.
- the disclosure herein is, thus, related to both a cleat and a cleat latching mechanism, which may be located in the sole of a shoe and made from various materials, including all plastic materials. None of these materials are subject to galvanic corrosion and thus will not wear or denigrate over time from exposure to chemicals, salts, or water.
- Removing the metal from cleat components reduces the contribution of the typical weight of the cleats by more than two thirds. With an average of 14 to 18 cleats in any given shoe design, this weight reduction can provide a meaningful potential improvement in athletic performance.
- the fin attachment devices and methods disclosed herein may be used in conjunction with surfboards and other watercraft.
- the fin attachment devices and methods disclosed herein are based upon the concept of spring locking.
- the spring locking may be part of the surfboard.
- a canted spring can be part of a housing built into a surfboard.
- the housing can receive a shaft that may be held in place by the canted spring.
- the canted spring can be part of the fin assembly.
- the systems and methods described herein are based, in part, on the concept of vertical, rather than of horizontal, locking forces for attachment of a device to an object, e.g.
- a fin device to watercraft object a cleat, wheel truck, or blade device to the sole of a shoe
- a toe plate device comprising a plurality of cleats to the sole of a shoe
- a wheel truck device to a skateboard, components of furniture, or the like.

Abstract
Devices and methods based upon the concept of a split ring having certain multiple interior angles to engage a stem or post having annular ring(s) with angular geometries that are complimentary to those of the split ring. The disclosure provides designs for a wide range of insertion and desertion forces between latch engagement stems and latch engagement bodies. Changes to insertion contact angles and contact area on engagement stems and corresponding changes to insertion contact angles and engagement areas on engagement bodies can significantly modify insertion forces required to engage various devices. Similarly, changes in degrees of angle between desertion angles and contact areas on engagement stems with corresponding changes in desertion angles and contact areas on engagement bodies will significantly modify the total desertion forces required to disengage various devices. Accordingly, the instant latching mechanism provides insertion and desertion forces that can be controlled independently of each other.

- Users of watercraft boards generally only have two methods of securing fins to their board. In particular, the user has to use either a set of screws or a snap mechanism, to attach the fins. The screw method may be quite time consuming for the watercraft user to practice. Additionally, screw and snap mechanisms may necessitate the use of multiple moving parts, any of which are subject to rusting, failure, and stress fatigue.
- Typically, toe and heel locking mechanisms, as described in the art, have a fin with a front end that has a detent or other feature that toes into the front end of the fin box to lock it into position. At the rear of the fin is a latch, whereby a linear spring may be used to latch the rear of fin into the fin box. A coil at one end of the spring moves into a cavity location within the fin box. The tension in the spring holds the spring coil in the fin box rear detent in order for the fin to stay engaged and in position.
- Toe and heel locking mechanisms are prone to failure, as the locking forces are horizontal to the bottom plane of the watercraft. Other toe and heel variations have locking mechanism without springs. Typically, a toe is locked into position using a T-slot, or other configuration. The fin typically has a forward pin, or other attachment piece, that is usually positioned at 90 degrees from the fin box. The pin moves downward into the capture slot and the fin is then pushed forward so that the toe of the fin is locked into position. Another detent at the rear of the fin, or another T-pin or like capture piece, moves downward into the fin box slot and is locked down by a vertically moving lever or a cylindrically positioned cam lever.
- Typically, in the variations mentioned above, an end-user has to provide a counter force along the horizontal plane to disengage the locking mechanisms. The reason this is undesirable is that in many watercraft situations a user might encounter such horizontal forces from the environment, for example, the watercraft fins could be exposed to such horizontal forces from contact with kelp, rocks, ropes, wood, sand, other watercraft, etc., and such contact could trigger the unwanted partial or full release of a fin. Therefore, prior art fin attachment systems may be prone to both mechanical and common use failures, and also may be too complicated to allow an user to quickly and effectively change his or her fin choices to adapt to a given situation.
- Conventional traction gear for footwear use a large number of individual traction elements, such as cleats, that are attached to the outsole of a shoe. Generally, individual cleats must be screwed into the sole of a shoe, involving much time. Further, the use of screw mechanisms to secure cleats to the soles of a shoe is not ideal inasmuch as the screws may loosen. Finally, conventional designs typically employ the use of metal attachment elements, which add considerable weight to the footwear.

The attachment methods and devices disclosed herein are applicable to a wide range of objects and devices. As discussed below, the attachment methods and devices disclosed herein can be advantageously used to couple a device to an object, wherein the device extends vertically from the object when attached, and is likely to encounter horizontal forces when attached to the object. For example, the attachment mechanisms disclosed herein can be used to attach a fin to a surfboard or other watercraft, a cleat to a shoe, a wheel truck to a rollerskate, rollerblade, or skateboard deck, a blade to an ice skate, components of components of furniture, or various other device/object pairs.
- As discussed below, some embodiments disclosed herein relate to attachment devices and methods that utilize spring locking means, e.g. canted coiled springs, cantilevered springs, split ring springs, split pin springs, or the like.
- Before describing the invention in detail, it is useful to describe an example environment with which the invention can be implemented. One such example is that of a surfboard. A surfboard is a type of watercraft that is generally longer than it is wide. The board generally forms a buoyant deck that a surfer may stand on while surfing. It will be understood, however, that surfboards may also for used for paddling, e.g., while sitting, laying, etc. Additionally, other methods of propulsion may be attached to the surfboard, such as a sail, e.g., for windsurfing. Many modern surfboards may be made of polystyrene or polyurethane foam. The boards may be covered with one or more layers of fiberglass cloth and a resin such as polyester or epoxy resin.
- Another environment with which the invention can be implemented is that of a shoe cleat design. A metal threaded component located on conventional cleats and like components in soles add significant weight to a shoe. Shoe weight and athletic performance are integrally related; the lighter the shoe the less force and thus the less energy is required by the athlete to maneuver. Less weight in the shoe assists the athlete in moving the foot and leg from one position to another more quickly. Shoe weight is a well-recognized property by athletes as critical to performance and is understood by shoe manufacturers. Footwear manufacturers describe and advertise shoe weight reductions as a point of comparison in the selling of their shoes against competitors.
- Metal cleats and their corresponding metal threaded inserts can be uncomfortable to the wearer of the shoe particularly over time as the polymers used to make the shoe sole begin to yield to the force of the metal studs. In time, the metal components become more prominent points of pressure between the bottom of the foot and the threaded cleat stud. This is not only uncomfortable, but can be a source of injury to the foot.
- A threaded cleat made from metal or plastic also may significantly limit potential design geometries of the cleat. Current cleat designs are constrained to circular cone shaped geometries due to the “threading in” requirement of a screw. Alternative geometries in cleat shapes are impractical. Attempting repeatable alignment of the cleat after threading it into the shoe sole is unattainable.
- All metallic components, particularly those located in the bottom of a shoe will be exposed over time to both alkaline and acidic materials in water borne environments, and thus subject those components to corrosion. Fertilizers and other chemicals typically found on athletic playing fields can have significant concentrations of both high pH (alkaline) and/or low pH (acidic) salts. These salts in combination with moisture and metal provide the anodic and cathodic requirements for deterioration of the metal. Plated steel or brass components most commonly used as cleat materials are highly vulnerable to galvanic corrosion.
- The disclosure herein is, thus, related to both a cleat and a cleat latching mechanism, which may be located in the sole of a shoe and made from various materials, including all plastic materials. None of these materials are subject to galvanic corrosion and thus will not wear or denigrate over time from exposure to chemicals, salts, or water.
- Removing the metal from cleat components reduces the contribution of the typical weight of the cleats by more than two thirds. With an average of 14 to 18 cleats in any given shoe design, this weight reduction can provide a meaningful potential improvement in athletic performance.
- As mentioned above, various embodiments of the attachment devices and methods disclosed herein may be used in conjunction with surfboards and other watercraft. In some embodiments, the fin attachment devices and methods disclosed herein are based upon the concept of spring locking. In some embodiments, the spring locking may be part of the surfboard. For example, in one embodiment, a canted spring can be part of a housing built into a surfboard. In some embodiments, the housing can receive a shaft that may be held in place by the canted spring. In another embodiment, the canted spring can be part of the fin assembly. In certain embodiments, the systems and methods described herein are based, in part, on the concept of vertical, rather than of horizontal, locking forces for attachment of a device to an object, e.g. a fin device to watercraft object, a cleat, wheel truck, or blade device to the sole of a shoe, a toe plate device comprising a plurality of cleats to the sole of a shoe, a wheel truck device to a skateboard, components of furniture, or the like.
- From time-to-time, the present invention is described herein in terms of exemplary environments, e.g. water. Description in terms of these environments is provided to allow the various features and embodiments of the invention to be portrayed in the context of an exemplary application. After reading this description, it will become apparent to one of ordinary skill in the art how the invention can be implemented in different and alternative environments.
- Although the figures provided herein are for the purposes of illustrating a fin locking system for watercraft, a cleat locking system for a shoe, a wheel-truck locking mechanism for a skateboard deck, and a locking mechanism for components of furniture, the particular embodiments disclosed herein and illustrated in the figures are for the purpose of illustration only, and should not be construed as limiting the scope of the embodiments disclosed herein.

FIGS. 3 , 4, and 5, a second version of thefin box 170 includes an elongated box configuration with rounded distal ends. Anupper portion 172 of thefin box 170 may have aradially extending flange 174. Theradially extending flange 174 includes a plurality of throughholes 176 or apertures formed therethrough about the entire periphery of theflange 174. Abottom portion 178 of thefin box 170 may have a reducedsize base 180 with a barb or a wedge shapedlip 182 at a bottom end of thefin box 170, as depicted inFIG. 5 . It is also contemplated that the reduced sized base may have two or more (e.g., four, etc.) barbs or wedge shapedlips 182. In one embodiment, the wedge shapedlip 182 may protrude out laterally about 0.060 inches from the reducedsized base 180. The wedge shapedlip 182 is angled such that thewedge 182 permits thebottom portion 178 to be inserted into thefin cavity 190 machined into the bottom surface of the watercraft, but does not permit the withdrawal of thefin box 170 therefrom. In some embodiments, an adhesive orquick setting epoxy 192 may be applied between thefin box 170 and thefin cavity 190. - The
fin cavity 190 formed in the watercraft may be sized slightly smaller than the outer periphery of thewedge lip 182 but slightly larger than the outer periphery of the reducedsize base 180, as shown inFIG. 5 . In some embodiments, theupper portion 172 of thefin box 170 may have aprotrusion 186 that is about 0.0050″ above atop surface 188 of theradially extending flange 174. In this manner, the coating covers theflange 174 and may be flush with the protrusion. Thefin box 170 may have twocircular fin apertures 184 disposed through theprotrusion 186. In some embodiments, thesefin apertures 184 may be spaced about 1.5″ from each other to receive corresponding posts of the fin. -
FIG. 6 is a diagram illustrating a top perspective view of a third version of a fin box in accordance with one embodiment of the invention.FIG. 7 is a diagram illustrating a bottom perspective view of the third version of the fin box ofFIG. 6 . Referring now toFIGS. 6 and 7 , a third version of thefin box 200 may have a similar configuration as the second version of thefin box 170. For example, the third version of thefin box 200 may have a wedge shapedlip 202 at a bottom outer periphery of thelower portion 204. The third version of thefin box 200 may have a different configuration from the second version of thefin box 170 in that theradially extending flange 206 does not have a plurality of through holes; rather, theradially extending flange 206 has at least oneannular groove 208 on its top surface. -
FIG. 8 is a diagram illustrating a top perspective view of a fourth version of a fin box in accordance with one embodiment of the invention.FIG. 9 is a diagram illustrating a bottom perspective view of the fourth version of the fin box ofFIG. 8 . Referring now toFIGS. 8 and 9 , a fourth version of thefin box 220 may have a similar configuration as the third version of thefin box 200. For example, the fourth version of thefin box 220 may have a wedge shapedlip 222 at a bottom outer periphery of thelower portion 224. In addition, a top surface of theradially extending flange 226 may have at least oneannular groove 228. However, unlike the third version of thefin box 200, a frusto-conical surface 230 may join theradially extending flange 226 and thebase 232. - Referring now to
FIG. 10 , in one embodiment, theposts 270 of thewatercraft fin 272 may be attached to thefin apertures 210 of thefin box 200.FIG. 10 illustrates the third version of thefin box 200 but it is contemplated that the manner in which theposts 270 are attached to thefin apertures 210 may be employed in the other versions of thefin box -
FIG. 11 is a diagram illustrating a cross sectional view of the post and fin aperture ofFIG. 10 illustrating a first version of the attachment between the post and fin aperture.FIG. 12 is a diagram illustrating a second version of the attachment between the post and fin aperture in accordance with one embodiment of the invention. Referring now toFIGS. 11 and 12 , which illustrate two versions for attaching theposts 270 of thewatercraft fin 272 to thefin aperture 210 of thefin box 200, thepost 270, may be sized and configured to slide withinfin aperture 210 of thefin box 200. - As illustrated in
FIGS. 11 and 12 , in one embodiment, theouter diameter 274 of thepost 270 is smaller than aninner diameter 276 of thefin aperture 210. Thepost 270 is also formed with a first undercutgroove 278A and 278B, which circumscribes thepost 270. In one embodiment, thefin aperture 210 may be formed with a second undercutgroove 280, which may be aligned to the first undercutgroove 278A and 278B. - In some embodiments, the
undercut grooves coil spring 282. In some embodiments, theundercut grooves grooves coil spring 282. In some embodiments, the dimensions vary from implementation to implementation; however, these dimensions are selected so that the canted-coil spring provides enough pressure to hold, for example, a fin device to a watercraft, such as a surfboard. - A canted-
coil spring 282 may be inserted into the second undercutgroove 280. In some embodiments, a canted coil spring may be a round-wire spring with inclining (canted), elliptical coils that deflect independently when compressed. Theentire spring 282 responds whenever any portion of the coil is deflected, permitting uniform loading at each contact point. By way of example and not limitation, a canted-coil spring 282 sold under the trademark BALSEAL™ Engineering of Foothill Ranch, Calif. may be inserted into the second undercutgroove 280. - In
FIG. 11 , thepost 270 may be inserted into thefin aperture 210 and removed therefrom by pushing and pulling thepost 270 into and out of thefin aperture 210. Thepost 270 illustrated inFIG. 12 may also be inserted and removed from the fin aperture but requires a greater push in force and pull out force compared to the structure shown inFIG. 11 . The reason is that the first undercutgroove 278A shown inFIG. 11 is beveled, whereas the first undercut groove 278B shown inFIG. 12 is squared off.

FIGS. 22-26 illustrate various embodiments wherein the attachment methods and devices are used for attaching a cleat device to a shoe object. Referring toFIG. 22 , one embodiment of acleat assembly 600 can include ahousing 602 with aninterior cavity 618 configured to receive a spring, such as asplit ring spring 604. In accordance with the embodiment shown inFIG. 22 , theinterior cavity 618 of thehousing 602 can be configured such that asplit ring spring 604 sits fully within theinterior cavity 618, with the cavity and the hole of thesplit ring spring 604 being coaxially aligned. In some embodiments, theinterior cavity 618 of thehousing 602 is configured such that ahousing lid 606 with an aperture 620 also sits within theinterior cavity 618 of thehousing 602. Theinterior cavity 618, the aperture of thesplit ring 604 and the aperture of thehousing lid 606 can be coaxially aligned. In the embodiment depicted inFIG. 22 , thehousing 602, thesplit ring spring 604, and thehousing lid 606 together form thedevice receptacle 610. The diameter of theinterior cavity 618 in which thesplit ring spring 604 sits is larger than the diameter of thesplit ring spring 604, in order to accommodate expansion of thesplit ring spring 604, for example when thedevice 608 is inserted into thedevice receptacle 610. The skilled artisan will appreciate that, although the components of thedevice receptacle 610 are depicted inFIG. 22 as being separate, that two or more of the components can, in some embodiments, be integral. - In some embodiments, the hosing lid and the housing are fixed or sealed together, for example, using glue, a threading mechanism (see, e.g.
FIG. 25 , discussed below), or any other means known by those skilled in the art appropriate for the intended purpose. Thesplit ring spring 604 can sit within theinterior cavity 618 of the sealeddevice receptacle 610. - As shown in
FIG. 22 , the top and bottom of the inside edge 624 of thesplit ring spring 604 that forms thecenter hole 612 can be beveled or angled at the top and/or bottom surface. For example, in some embodiments, theinside edge hole 612 of thesplit ring spring 604 can be angled at a 15°, 20°, 25°, 30°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 120°, or greater angle. In preferred embodiments, theinside edge hole 612 of thesplit ring spring 604 form a 90° angle. In some embodiments, the angles of the top 624 a andbottom edges 624 b of thehole 612 of thesplit ring spring 604 are different. Anysplit ring spring 604 can be used in the embodiments disclosed herein, for example from commercially available sources, or specifically manufactured for the attachment devices disclosed herein according to methods known to those skilled in the art. - As shown in
FIG. 22 , thedevice 608, e.g. the cleat shown inFIG. 22 , has atop portion 616 and a bottom portion comprising apost 622, which is inserted through theaperture 626 of thehousing lid 606 of thedevice receptacle 610, through thehole 612 in thesplit ring spring 604, and into theinterior cavity 618 of thehousing 602. Thepost 622 can have anannular groove 628. Preferably, thegroove 628 is defined byangular edges edges interior hole 612 of thesplit ring spring 604, such that when thepost 622 is inserted into theinterior cavity 618 of thedevice receptacle 610, thesplit ring spring 604 rests around thegroove 628, as shown inFIG. 23 . In some embodiments, theannular groove 628 is cut so that the total thickness of the groove 648 is approximately the same as the thickness 646 of thesplit ring spring 604. - The disclosed invention does not require the use of threads. Cleats as shown in
FIG. 22 are plugged into place rather than threaded into place. This provides shoe designers an unlimited range of possible cleat geometries. Alignment of the cleat is provided for in the design of the shoe sole or the cleat spring housing. - The material used for the insole latching mechanism is, preferably, a high impact, high strength polymer designed to be used as a spring. The
spring 604 used in this invention is basically a split ring design with an interior configuration matched for the engagement and latching to the configuration of the cleat stem orpost 622. Changes to these mating geometries along with the size of thesplit ring 604 will, in certain embodiments, allow the designer to choose both the insertion and desertion pressure of the cleat into the shoe. This is a useful property as it allows shoe designers to best match the ease of cleat extraction from the shoe against the fail safe properties required during its use in a selected shoe product. (i.e. football cleats vs. golf cleats). - The
spring 604 anddevice receptacle 610 are designed to spread the pressure from thecleat 608 to the foot over a wider area (5:1) over current metal treaded systems. Thus shoe sole polymers do not yield to the improved cleat systems as do the current metal threaded studded cleats. This improvement yields a considerably more comfortable shoe both as purchased as well as over the life of the shoe. Injury to the foot from excessive cleat pressure to the foot is significantly minimized, if not eliminated. - As shown in
FIG. 23 , upon insertion, theouter diameter 632 of thepost 622 pushes thesplit ring spring 604 outward until thesplit ring spring 604 is seated in theannular groove 628 of thepost 622 when assembled. The restorative force of thesplit ring spring 604 around thegroove 628 of thedevice 608 holds thedevice 608 in place within thedevice receptacle 610. As shown inFIGS. 22 and 23 , in some embodiments, thedistal end 634 of thepost 622 can be beveled as well, in order to facilitate insertion and desertion of thecleat device 608 into the device receptacle. When assembled, the bottom face 660 of thepost 622 of thecleat device 608 rests against thehousing lid 606. In some embodiments, thehousing lid 606 can have a detent that is complementary to the shape of the bottom face 660 of thepost 622 of thecleat device 608. The bottom face 660 of thepost 622 of thecleat device 608 can be any shape, such as circular, oval, square, rectangular, etc. Preferably, the shape of the bottom face 660 of thepost 622 of thedevice 608 and the complementary detent in thehousing lid 606 are asymmetrical, such that thecleat device 608 is less likely to rotate, and the cleat device may retain some, e.g. predetermined alignment with the shoe to which it is attached. - In some embodiments, the bottom portion of the
device 608, e.g. the cleat, can include ahole 638 therethrough, to facilitate disassembly of thedevice 608 from thedevice receptacle 610. - The components of the
device receptacle 610 can be made from any material, such as rigid polymers, ceramics, stainless steel, composites, polymer coated metal, and the like. In some embodiments, the components of thehousing 602, thesplit ring spring 604 and thehousing lid 606 are made from a rigid plastic material. -

FIG. 33A is a diagram illustrating an exemplary latching system. As depicted inFIG. 33A , the latching system relies on the ability to design a wide range of insertion and desertion forces between thepost 622 to thespring 604. Changes to the distal 634 on thepost 622 and a corresponding changes to thetop edge 624 a in thespring 604 can, in certain embodiments, modify the total insertion force required to engage thepost 622 to be fastened into thespring 604. This modification may, in certain embodiments, be substantial. Similarly, changes in degree of angle between thebottom edge 630 b on thepost 622 with a corresponding change inbottom edge 624 b on thespring 604 can, in certain embodiments, modify the total desertion force of thepost 622 to be fastened. This modification may, in certain embodiments, be substantial. As the angles increase from 0 to 90 degrees the force required to engage or disengage increase. Angles approaching 90 degrees make it impossible to either engage or disengage thepost 622 to be fastened while lower angles, preferably those less than 30, 25, 20 or 15 degrees make insertion and desertion force required relatively small. Accordingly, insertion and desertion force can be controlled independently of each other. Changes in eitherangular edges 630 b or distal 634 of thepost 622 control independently the range of forces available for either insertion or desertion while changes in thespring 604 control equally changes in insertion/desertion force range. Similarly, changes in the tensile strength of thespring 604 material have an equal change in the pressure range of both the insertion/desertion forces. The multiplicity of methods to choose from to control latching insertion and desertion forces allows considerable range in latching applications and design freedom. -
