Self-aligning snowboard binding

Abstract

A self-aligning snowshoe binding is provided that simplifies the process of strapping in to a snowboard. The binding includes a self-aligning buckle that includes two mating clips, and each clip contains a pair of offset magnets. One clip is rigidly attached to a snowboard binding and the other, mating, clip is connected to an ankle or toe strap via a tensioning mechanism. The opposite side of the ankle/toe strap is secured to the binding with an adjustable mechanism. When the two clips are brought proximate each other, the magnets engage to create a loose buckling. When tension is applied to the engaged clips, the clips interlock such that they will remain together as long as tension in the strap is maintained.

DESCRIPTION OF THE DISCLOSURE

(17) The self-aligning snowshoe binding of the present invention simplifies the process of strapping in to a snowboard through the use of a self-aligning buckle that includes two mating clips, and each clip contains a pair of offset magnets. One clip is rigidly attached to a snowboard binding and the other, mating clip, is connected to an ankle or toe strap via a cam actuated lever or other suitable mechanism. Such mechanisms may include a ratcheting system in which the strap is partially attached to a ratchet and the end of the strap is attached to the top clip, a twist nob configured to tighten the strap, or a looping a strap threaded through the top clip which can be held in a position that keeps tension on the strap by a hook and loop fastener or similar.

(18) The opposite side of the ankle/toe strap is secured to the binding with an adjustable mechanism. When the two clips are brought within about inch of each other, the magnets engage to create a loose buckle condition. The cam lever is depressed and brought in-line with the ankle/toe straps to tighten the boot into the binding. When the cam lever is depressed, the magnetic clips lock together in a hooking fashion such that they will stay locked together as long as tension in the strap is maintained. The tension can be preset by adjusting the length of the heel or toe strap using an adjustable mechanism on the outboard side of the corresponding ankle/toe strap. Once the preset tension is configured, further changes to the adjustable mechanism are generally not required.

(19) In an embodiment, as depicted in FIGS. 1-3, a binding-boot assembly 20 includes a boot 22 secured in a binding assembly 24. The binding assembly includes a lever 1, a connector 2, a pivot point 3, a strap 4, an adjustable mechanism 5, a top magnetic clip 6, a bottom magnetic clip 7, and a baseplate 8. Lever 1 is used to tighten or loosen strap 4 around boot 22. When lever 1 is depressed, strap 4 tightens around boot 22; when lever 1 is raised, strap 4 loosens. Lever 1 is connected to pivot point 3 (as can be seen more clearly in FIG. 9) that is rigidly attached to strap 4 and is connected to connector 2. Connector 2 is connected to both lever 1 and top magnetic clip 6 with pin joints or another suitable mechanism. Bottom magnetic clip 7 is rigidly attached to baseplate 8 of the binding assembly. Adjustable mechanism 5 is attached rigidly to strap 4 and connects strap 4 to baseplate 8. In this way, adjustable mechanism 5 allows the user to change the length of binding strap 4. This allows the binding to be compatible with multiple boot sizes and for the user to adjust how tight strap 4 will be around boot 22 when lever 1 is closed.

(20) Turning to FIG. 4, a pair of counterpart magnetic clips, a top magnetic clip 6 and a bottom magnetic clip 7 are depicted apart from the rest of binding assembly 24. Each of these magnetic clips contains two magnets imbedded into a front surface. Top clip 6 includes a first magnet 9 and a second magnet 10 while bottom clip 7 includes a third magnet 11 and a fourth magnet 12. Magnet 9 and magnet 11 have the north side facing upwards while magnet 10 and magnet 12 have the south side facing upwards. The purpose of the magnets is to draw the two clips together to form a loose buckle condition. A hooking portion 13 (e.g., 13a, 13b) is included on each of the clips and will draw top clip 6 and bottom clip 7 together due to magnetic attraction prior to full engagement. When the clips are fully engaged, two angled portions of hooking parts 13 fit together in a fashion such that the clips cannot be pulled apart. In a preferred embodiment, the angled portions have a 45 degree angle. A channel 14 (e.g., 14a, 14b) is an open area on each clip that passes through the clip to prevent snow from getting stuck inside, which could prevent the clips from fully engaging. When top clip 6 and bottom clip 7 engage, any snow that is inside the clips can be pushed out through channel 14. In certain embodiments, a wall 15 (e.g., 15a-15d) can protrude from each edge of the base of each clip. Walls 15a-15d make the clips resistant to separating from shear force. Walls 15a-15d also guide the clips when they transfer from the partially engaged state to the fully engaged state, as shown in FIGS. 7A-7B.

(21) FIGS. 5A-8B detail three identified stages that take place as the clips are engaged when the user operates the binding. The positioning and alignment of magnets 9-10 in top clip 6 and magnets 11-12 in bottom clip 7 serve to assist with the proper alignment of top clip 6 and bottom clip 7 prior to full engagement. Magnet 9 and magnet 11 may have, for example, the north side of the magnets facing upwards while magnet 10 and magnet 12 have the opposite side, south in this example, facing upwards. With this configuration (or similar), when top clip 6 and bottom clip 7 are brought relatively close together, as shown in FIGS. 5A-5B, magnet 9 and magnet 12 are attracted to each other and magnet 10 and magnet 11 are attracted to each other.

(22) When the magnets are drawn together, top clip 6 and bottom clip 7 will be partially engaged, as shown in FIGS. 6A-6B. This partial engagement occurs when the clips are brought close enough together (such as about an inch or less depending on the size and strength of the magnets) for the magnets to attract and pull top clip 6 into contact with bottom clip 7. In this position, the clips can be separated easily by applying a vertical force but are resistant to separating from shear force because of walls 15a-15d, which also guide the clips when they transfer from the partially engaged state to the fully engaged state.

(23) Top clip 6 and bottom clip 7 are shown in a fully engaged state in FIGS. 7A-8B. In this position, the clips hold firmly in place due to the tension created, such as when lever 1 or a similar mechanism is closed as illustrated in FIGS. 9-10. In the fully engaged state the clips are resistant to being separated by shear or vertical forces that may be applied. This resistance to separation is due in part to having a connection mechanism that is aligned when the magnets attract and fully engaged when opposing tensions are applied to each clip. For example, hooking portion 13a of clip 6 and hooking portion 13b of clip 7 interlock when in the binding is in the fully engaged position. The counterpart connection of hooking portions 13 is most clearly illustrated in FIG. 10. This allows the boot to be securely fastened to the board when opposing tension is applied to the clips, such as when lever 1 is engaged. The user can easily release boot 22 from the binding by releasing the opposing tension, such as by opening lever 1 and separating the clips. It will be understood that other suitable mechanisms may be used for applying tension, such as a ratchet or similar, and that other interlocking mechanisms may be used such as one or more aligned tongue and grooves.

(24) The transition into the fully engaged state occurs when lever 1 is closed or when the binding is tightened in another fashion. This transition is shown in FIGS. 9-10, with FIG. 9 showing lever 1 open and FIG. 10 showing lever 1 closed and the clips in the fully engaged position.

(25) As noted, FIG. 9 illustrates the clip, lever and strap system in the open position. In this position, the user is free to insert a boot into the binding because the clips have not been engaged and lever 1 is open, so strap 4 is loose. In FIG. 10, the binding is shown in the locked and tightened position. In this position, clip 6 and clip 7 are fully engaged and can only be separated if lever 1 is released. Strap 4 is also pulled tight around the user's boot. The closing of lever 1 as shown in FIG. 10 causes the clips to convert from the partially engaged position to the fully engaged position as mentioned above.

(26) Turning to FIG. 11, a self-aligning snowshoe binding process diagram 100 is shown. In operation, a user inserts a boot into the binding at step 104. The user then grabs a binding strap and pulls the strap over the top of the boot while simultaneously moving a first clip close to a second clip at step 108. When the clips are close enough together at step 112, magnets embedded in the clips will pull the two clips together and create partial engagement of the clips. Once the clips are partially engaged, the user places tension on the buckle at step 116. The tension causes the clips to engage fully, which allows the strap to be tightened around the user's boot. To release the boot from the binding, the user releases the tension at step 120 and disengages the magnetic clips. This is possible because when tension is removed, the clips return to the partially engaged position, and so can be easily separated. Once the clips are separated, the boot can easily be removed from the binding.

It will be understood by those skilled in the art that various changes, omissions and additions may be made to that which is specifically disclosed herein without departing from the spirit and scope of the present invention.
