  • Various riding styles and terrain conditions may also recommend a particular type of board flex.
  • a snowboard may be designed with a particular flex pattern.
  • Snowboard bindings secure a rider to the snowboard, and typically are in the form of a rigid baseplate that receives the rider's boot and a rigid hold-down disk that is received in, and attaches, the baseplate to the snowboard (known as a "tray” style binding).
  • the rigid hold-down disc is provided with openings or slots that are compatible with a pattern of threaded inserts (e.g., "4x4" or 3D (TRADEMARK)) arranged on the snowboard. Fasteners are passed through the hold down disc and screwed into the inserts, attaching the baseplate to the board.
  • the rigidity of both the baseplate and the hold-down disc may create a dead spot that resists flexing of the snowboard underneath and/or adjacent the binding.
  • 'baseless' bindings do not include a floor or base so that a rider's boot rests directly on the snowboard.
  • Baseless bindings are believed to allow greater board flex as compared to tray style bindings.
  • An example of a baseless binding is described in US Patent Application Publication No. 2008/0030000 A1 , assigned to The Burton Corporation, which is the assignee of the present application.

  • aspects of the invention are discussed herein in connection with a snowboard.
  • hold-down device refers generally to a component of a binding that may be used to secure the binding to a gliding board. Although referred to as a hold-down disc, in some embodiments discussed herein, it is to be appreciated that the hold-down device may take other overall shapes and, consequently, the hold-down device is not limited to being disc-shaped, nor to constituting a component that is separate from the binding base.
  • a binding for a snowboard may include a strap type binding (also known as a tray binding) having one or more of a toe strap, an instep strap and a shin-strap, a step-in binding, hybrid strap/step-in bindings, and other arrangements for retaining a rider's boot to a snowboard.

  • the binding 20 and snowboard 22 are illustrated both in an un-flexed state (represented by solid lines) and a flexed state (represented by dashed lines).
  • the board 22 curves beneath and adjacent to the binding as medial and lateral base regions 24, 26 of the binding 20 move, relative (e.g., pivot) to one another in response to board flex. This movement may be characterized about an axis that extends substantially in a heel-toe direction of the binding base (i.e., that extends into and out of the page in FIG. 1 ).
  • FIG. 2A Parallelogramming, which may include medial and/or lateral regions rotating on an upper surface of a board or moving oppositely/relative to one another in the heel-toe direction of the binding, is represented by the dashed lines shown in FIG. 2A .
  • the dashed lines in FIG. 2B represent a type of bowing, which includes toe end portions 28 of the medial and lateral regions moving away from one another. It is also to be appreciated that bowing may include central portions and/or heel end portions of the medial and lateral regions spreading away from one another.
  • FIGs. 3 and 4 show a binding 20 that includes a baseplate characterized by medial and lateral base regions 24, 26 and medial and lateral sidewalls 32, 34.
  • the base regions are arranged to move relative to one another (e.g., flex or pivot) about a heel-toe axis 30, at least in part by having a gap or separation between the two regions at the hold-down device receiving area.
  • the hold-down disc receiving aperture in a conventional tray binding in contrast, is completely surrounded by base material that extends from one sidewall to the other providing an uninterrupted rigid base or floor between the sidewalls that resists relative flexing of the medial and lateral base portions.
  • the base is secured to a snowboard 22 by a hold-down device 44 having openings or slots 77 for receiving fasteners or other hardware for attaching to a binding interface in the snowboard, such as fastener inserts or a t-nut captured in a channel 90.
  • the hold-down device has first and second portions 46, 48 that are connected by a hinge 50.
  • the hinge allows the first and second portions 46, 48 of the hold-down device 44 to move in response to bending forces of the board away from the binding (i.e., outwardly).
  • the rear, or heel end, of the binding base may be open, as shown, or otherwise arranged to permit inward flexing of the medial and lateral base regions in response to bending of the board.
  • Other configurations of binding components that facilitate bending of a snowboard when a binding is mounted thereto are contemplated, certain of such other arrangements being described herein in greater detail.
  • Configuring the base to facilitate board flexing, as compared to tray style bindings, such as by interrupting the base at the hold-down device receiving area, and at locations rearwardly and forwardly thereof, may render the binding susceptible to parallelogramming or bowing.

  • Certain embodiments of a bridge may be constructed to flex more readily about an axis extending in the heel-toe direction of the binding than in other directions, such as about a vertical axis of the binding (as taken when ridden) that is associated with parallelogramming. This is accomplished in the embodiment of FIG. 3 by having the thickness T of the bridge 52 smaller than a width W of the bridge.
  • the bottom of the bridge may be located above the bottom of the base region as is illustrated.
  • the bridge 52 may have a thickness of about 5 mm and a width of about 20 mm (a ratio of about 1:4), although other widths, thicknesses, and ratios are also possible. It is to be appreciated that a bridge may be constructed to be more flexible about a heel-toe axis than in other directions through other approaches, such as by being made of composite that is oriented to allow flexing about a heel-toe axis to a greater degree than about axes in other directions. Additionally or alternatively, other features may be incorporated into a bridge to allow movement like that shown in FIG. 1 , including inclusion of a pinned hinge, living hinge or other flexible connections that may allow movement about the heel-toe axis yet resist bending in other directions. It is also to be appreciated that certain binding base embodiments may lack a bridge altogether.
  • a heel hoop 54 may also resist unwanted distortion. This may be accomplished with a heel hoop that flexes more readily about a heel-toe axis of the binding base than in other directions.
  • a heel hoop may be constructed with a thickness T that is less than a width W to allow binding movement as shown in FIG. 1 .
  • a flexible arrangement such as a pinned hinge, living hinge, expansion joint, compression joint, and the like, may be incorporated into a heel hoop.

  • Embodiments of the binding base and/or hold-down device may include one or more rotation stops 80 to limit a range of angular positions in which the binding base may be mounted to a snowboard. Limiting the range of angular positions may help ensure a minimum amount of engagement between the binding and hold-down device, consequently ensuring a secure mounting of the binding to a snowboard.
  • the stop may include a pair of shoulders on each of the first and second portions of the hold-down device. A first shoulder or protrusion of each pair may engage a corresponding stop (such as a shoulder or protrusion) on the binding to prevent rotation beyond a particular angle in the clockwise direction.
  • a second shoulder or protrusion of each pair may contact a corresponding stop on the binding to limit rotation in the counter clockwise direction.
  • a stop may be positioned on only one of the first and second hold-down portions and corresponding regions of the binding, while other embodiments may lack stops altogether. It is also to be appreciated that the stop may be integral to a binding base and/or to a hold down device, and may be separate from fastening hardware of a snowboard binding.
  • Embodiments of the binding may be compatible with a wide variety of snowboard binding mounting systems.
  • the hold-down device shown in FIGs. 3-6B is configured to mount the binding to a snowboard arranged with the ICS (TRADEMARK) channel-style binding interface sold by The Burton Corporation.

  • FIGs. 10A and 10B show an alternate embodiment of a hold-down device that is configured to mount a binding 20 to a snowboard 22 having a channel-type binding mount system, such as is shown in FIG. 3 .
  • the illustrated embodiment includes first and second portions 46, 48 that each has a clamping plate 82 and a positioning plate 84, like the embodiment of FIGs. 9A and 9B .
  • Each of the first and second portions is connected to the other by a key 86.
  • the key 86 allows the portions 46, 48 to flex relative to one another about a heel-toe axis perpendicular to the key.
  • the key 86 shown in FIGs. 10A and 10B may help position first and second portions 46, 48 of the hold-down device 44.
  • the key 86 may hold each of the first and second portions apart from one another at a fixed distance, preventing the positioning plates 84 from moving toward one another and thus away from corresponding portions of a binding. This is accomplished in the embodiment of FIGs. 10A and 10B by the bend 88 in the key that is threaded through each portion 46, 48, as shown in FIG. 10B .
  • the key of FIGs. 10A and 10B may, additionally or alternatively, extend downward so as to fit into the channel 90 of a snowboard 22 and interact with edges of the channel.
  • Interaction between the key 86 and edges of the channel 90 may resist the key from rotating about an axis that extends upward from a top surface of the snowboard.
  • the key may, in turn, limit each of the first and second portions of the hold-down device from rotating about the upper surface through interaction between the portions of the bends and the key. This interaction should resist parallelogramming.
  • a two part key (one part associated with each of the first and second portions) may alternatively be used.
  • Embodiments of the hold-down devices may be constructed of different materials, including but not limited to steel, aluminum, plastics, composite materials, and others.
  • the embodiments of FIGs. 3-5, 6, 7, and 8 may be particularly suitable for plastic constructions, including fiber reinforced plastic constructions.
  • the embodiments of FIGs. 9A-9B and 10A-10B may be suitably constructed with plastic positioning plates and metal clamping plates and a metal key. It is to be appreciated, however, that other materials may be used and are also contemplated.
  • a footbed 92 may be positioned over the medial and lateral base portions 36, 38 to provide a surface to receive a rider's boot.
  • One embodiment of a footbed is shown in FIGs. 11A and 11B .
  • the footbed 92 includes a ramped toe support 94 and a heel support 96 that each mate to the binding 20.
  • the footbed 92 also includes a central portion 98 that overlies the hold-down device 44 and the medial and lateral base portions 36, 38 of the binding.
  • the central portion 98 of the footbed may be lifted away from the binding to provide access to the base portions of the binding to receive a hold-down device 44 when the binding is mounted or removed from a snowboard or when the binding position is adjusted.
  • the central portion 98 is connected to the ramped toe support 94 by a living hinge 100, although other types of connections are also possible. This hinge allows the central portion to be pivoted upwards, while remaining connected to the binding.
  • a footbed may be connected to bindings in different ways.
  • the ramped toe support 94 of the footbed 92 is fastened to the bridge 52 that connects toe ends of the binding medial and lateral regions.
  • the heel support 96 includes clips that are received in grooves at the heel end of the binding. It is to be appreciated that other connections are contemplated.
  • Tests were performed to characterize the affect on board flex of a binding constructed according to embodiments of the invention.
  • the tests were performed on an EST (TRADEMARK) baseless binding for use with a channel mounting system generally like that represented in US Patent Application Publication US 2008/0030000 A1 , a binding constructed generally as represented in FIG. 3 including a hinged hold-down device, and a TRIAD (TRADEMARK) conventional tray style binding including a conventional hold-down disc.
  • Each of the bindings was constructed from a common material (a plastic formed through a selective laser sintering (SLS) prototyping process) and were of a medium size constructed for a rider's right foot.
  • SLS selective laser sintering
  • a 2009 Hero (TRADEMARK) snowboard with a channel mounting system was used for each test.
  • a fourth test was performed on the snowboard without a binding for purposes of comparison.
  • Table 1 shows the results of a three-point bend test.
  • a board/binding assembly was supported on two points lying outside of the medial and lateral sides of the binding and separated from one another by a span of 480 mm.
  • a tensile/compression testing machine was used to deflect a third point of the board/binding assembly, positioned in the foot receiving area of the binding, downward by a distance of 40 mm.
  • the amount of force required to achieve 40 mm deflection was recorded for each board/binding assembly, and is shown in TABLE 1 below.
  • the three-point bending test was also performed on a board without a binding.
  • Table 2 shows the change in load and percent change in stiffness associated with each of the binding/board combinations (tests 1-3 of Table 1) after having subtracted the stiffness of the board alone (test 4 of Table 1). Table 2 also shows the percent increase in stiffness associated with each binding, relative to the board alone. (The binding with the hinged hold down disc (Test 2) was less stiff than the conventional binding (Test 3). Table 2 Test # Binding ⁇ Load binding , N % inc in stiffness 1 Cartel EST (baseless binding without a hold-down device in foot receiving area) 380 12 2 Binding as shown in FIG. 3 including a hinged hold-down device 510 16 3 Triad (tray style binding with conventional hold-down disc) 635 20
  • a second test was performed to determine the stiffness of each of the bindings described above with respect to Table 1, exclusive of board flex characteristics.
  • Each binding was mounted to a snowboard split into two pieces in the edge-to-edge direction beneath the binding mount surface.
  • the split board/binding assemblies were supported on two rollers lying outside of the medial and lateral sides of the binding and separated from one another by a span of 135 mm.
  • a tensile/compression testing machine was used to deflect a third point of the split board/binding assembly, centered in the foot-receiving area of the binding, with a 300 N force, where deflection and stiffness of the split board/binding were recorded. Table 3 below shows the results of this testing.
