Title: Tool free system for adjusting the mounting location of an engagement member

Description:
RELATED APPLICATION 
     This application is a continuation-in-part of and claims the benefit under 35 U.S.C. § 120 of the filing date of U.S. patent application Ser. No. 09/560,094, now U.S. Pat. No. 6,416,075, filed Apr. 28, 2000, which is hereby incorporated by reference in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The invention relates to a tool free system for adjusting the mounting location of an engagement member and, particularly, relates to a system for repositioning the mounting end of an engagement member within a base while the base is mounted to a substrate and without the assistance of external tools. 
     BACKGROUND OF THE INVENTION 
     Binding devices are employed to secure a rider to boards and other devices configured for gliding, such as snowboards, snow skis, water skis, wake boards, surf boards and the like. For purposes of this patent, “gliding implement” will refer generally to any of the foregoing boards as well as to other devices which allow a rider to traverse a surface. 
     Certain types of bindings, known as strap or tray bindings, employ elongated straps to mount a rider&#39;s foot or boot to a gliding implement. A strap type snowboard binding  10  is shown in FIG.  1  and includes a baseplate  12  adapted to receive a rider&#39;s boot  14  and one or more straps extending across the boot receiving area for securing the boot  14  to the binding  10 . Typical are a toe strap  16  and an ankle strap  18 , each of which includes a ratchet strap  20  and a boot engagement strap section  22  that are separated from each other to provide an opening for the rider to place his or her boot  14  into the binding  10 . The strap portions  20  and  22  are then rejoined and tightened around the seated boot  14  to securely hold the boot  14  on the snowboard  1 . 
     An end of each strap section  20  and  22  includes an eyelet  24  that is registrable with a mounting hole  26  extending through a sidewall of the baseplate  12 . A threaded bolt is inserted through the aligned openings and then tightened with a t-nut or other fastener to secure the strap section to the binding. Because different mounting locations of a strap are better suited to a particular style of riding, and because the comfort and fit of a boot to a binding may be varied by adjustment of the strap position, strap-type snowboard bindings typically include a series of spaced mounting holes  26  in the sidewall allowing a rider to selectively change the strap mounting location. Using a screwdriver, wrench and/or other tool, the rider loosens the fastening hardware and then repositions the strap so that the eyelet  24  aligns with a different mounting hole  26 . The hardware is then reassembled and tightened with the appropriate tools so that the toe and/or ankle strap extends across the rider&#39;s boot in a location suitable for the type of riding intended or for the desired comfort. 
     Recently, Burton Snowboards, the assignee of the present application, introduced a snowboard binding with a toe strap that was moveable from a first mounting location to a second mounting location on the binding without requiring the rider to use external tools. As shown in FIG. 2, the toe strap again included a ratchet strap section  20  and a boot engagement section (not shown). Two generally cylindrical shaped bosses  28  projected sideways from a mounting end of each section of the toe strap. The bosses  28  were engageable with a pair of opposed catches  30  (first mounting location) located in respective slots on each side of the baseplate. A second pair of opposed catches  32  (second mounting location) were located in each slot approximately twenty millimeters rearward from the first pair of catches  30 . 
     To move the toe strap from the first mounting location to the second mounting location, the binding  10  first had to be removed from the snowboard  1  because the top surface of the snowboard  1  at the bottom  34  of the slot prevented the strap from being moved downward out of engagement with the catches  30 . Once the binding  10  was removed from the snowboard  1 , the top portion of the toe strap extending away from the baseplate was grabbed and pushed toward the bottom of the baseplate, moving the strap past the bottom  34  of the slot and freeing the bosses  28  from the first pair of catches  30 . The strap  16  was then slid rearwardly until the bosses  28  were aligned with the second pair of catches  32 . Drawing the top of the strap  16  upwardly seated the bosses  28  in the other pair of catches  32 , placing the toe strap  16  in the second mounting location. To secure the binding  10  to the board with the toe strap in the new mounting location, a hold down mount, e.g., a hold down disc (not shown), was nested in a slightly smaller aperture in the baseplate floor. Screws or bolts were then passed through openings in the hold down mount and mated to threaded inserts in the snowboard  1 , mounting the baseplate  12  to the snowboard  1 . While this Burton arrangement did not require tools to reposition the toe strap between the first and second mounting locations on the binding, tools were necessary to first unfasten the binding from the snowboard, providing the necessary clearance for advancing the toe strap sufficiently beneath the bottom of the baseplate to release the bosses  28  from the catches  30  or  32  at the first or second mounting location and move the toe strap to the other mounting location. Thus, the prior Burton binding did not provide on-board, tool free adjustment of the toe strap mounting location. 
     Although the bottom  34  of the toe strap slot was open in the Burton binding shown in FIG. 2, the toe strap did not fall out of the slot because the baseplate was mounted flush to the snowboard surface. The portion of the sidewall where the ankle strap was mounted, however, was elevated well above the snowboard surface. A slotwall-type mounting arrangement was not suitable here as the ankle strap could have slipped out of the baseplate without a snowboard surface available to seal the slotwall bottom opening. Consequently, in the Burton binding configured with a tool free toe strap, the ankle strap was mounted to the outside of the baseplate sidewall with a screw and t-nut in the conventional fashion. 
     SUMMARY OF THE INVENTION 
     In one embodiment in accordance with an aspect of the invention there is provided a tool free system for adjusting a mounting location of an engagement member on a base while the base is mounted to a substrate. The engagement member is conformable to an object which is to be restrained and the base is adapted to receive at least a portion of the restrained object. The engagement member has a mounting end that is engageable with the base at a first mounting location and is arranged for tool free disengagement from the first mounting location and movement to a second mounting location while the base is attached to the substrate. The engagement member may be moveable by a user to disengage the mounting end from the first mounting location. 
     In another aspect of the invention, a binding for securing a foot or a boot to a gliding implement includes a base that receives the foot or boot and is attachable to the gliding implement. At least one strap that is conformable to a surface of the foot or boot is engageable on said base at a first mounting location and at a second mounting location. The at least one strap is disengageable tool free from the first mounting location and movable to said second mounting location while remaining attached to said base and while said base is attached to the gliding implement. 
     In another aspect of the invention, a binding for securing a foot or a boot to a gliding implement includes a base that receives the foot or boot and is attachable to the gliding implement. At least one strap that is conformable to a surface of the foot or boot as it is tightened thereagainst is mountable to the base at a first mounting location. The base and the at least one strap include complementary locking members for attaching the at least one strap to the base at the first mounting location, and one of the at least one strap and the base are biased to urge the complementary locking members into engagement while the at least one strap is in an untightened state. 
     In another aspect of the invention, a snowboard binding includes a baseplate with an aperture and a complementary hold down disc for mating with the aperture and securing the baseplate to the snowboard. The baseplate includes a pair of sidewalls and a heel hoop, and a highback extending from a rear portion of said baseplate. At least one strap that is conformable to a surface of the boot as it is tightened thereagainst includes a mounting end portion. At least one of said pair of sidewalls and said heel hoop defines a slot which receives the mounting end portion of the at least one strap in a first fixed mounting location. The mounting end portion of the at least one strap is releasable, tool free, from said first fixed mounting location within the slot while said baseplate is attached to the snowboard and then repositionable, tool free, in a second fixed mounting location within the slot. 
     In another aspect of the invention, a binding for securing a foot or a boot to a gliding implement includes a base for receiving the foot or boot that is attachable to the gliding implement, and at least one foot or boot engagement member is conformable to a surface of the foot or boot as it is tightened thereagainst. The binding also includes means for allowing tool free adjustment of said at least one foot or boot engagement member from a first mounting location to a second mounting location while the base is attached to the gliding implement and without disconnecting the strap from the base. 
     In another aspect of the invention, a method for tool free adjusting the mounting location of a foot or boot engagement member on a binding includes providing a binding having a base and at least one foot or boot engagement member. The binding includes first and second mounting locations for the at least one foot or boot engagement member, and is mounted to the gliding implement. The method also includes adjusting the at least one foot or boot engagement member from the first mounting location to the second mounting location without tools while the binding is mounted to the gliding implement and without disconnecting the at least one foot or boot engagement member from the base. 
     In another aspect of the invention, a snowboard binding includes a base, at least one binding strap, and a detent supported by the base and adapted to mount the at least one binding strap to the base in at least two mounting positions. The detent and the at least one binding strap are configured to allow the at least one binding strap to be selectively moved between the at least two strap mounting positions without tools while the base is attached to a snowboard by applying a force to a resilient member. 
     In another aspect of the invention, a snowboard binding includes a base having a bottom and at least one side flange supported by the bottom. The at least one side flange has a front slot that extends from a top of the at least one side flange through the bottom of the at least one side flange. A toe strap is positioned at least partially within the front slot, and at least two front strap mounting features are adapted to engage the toe strap with the base at at least two mounting positions. The at least two front strap mounting features are positioned within the front slot and adapted to allow the toe strap to be moved between the at least two mounting positions without tools while the base is attached to a snowboard. The snowboard binding may also include a rear slot that extends from a top of the side flange toward a bottom of the side flange and an ankle strap positioned at least partially within the rear slot. At least two rear strap mounting features are positioned within the rear slot and adapted to engage the ankle strap at at least two rear mounting positions. The at least two rear strap mounting features are adapted to allow the ankle strap to be moved between the at least two rear mounting positions without tools while the base is attached to a snowboard. 
     Another illustrative embodiment of the invention is directed to a snowboard binding including a base, at least one binding strap having a resilient end, and at least two strap mounting features supported by the base. The strap mounting features are adapted to mount the at least one binding strap to the base in at least two mounting locations. The strap mounting features and the binding strap are configured to allow the at least one binding strap to be selectively moved between the at least two strap mounting locations. The resilient end tends to retain the strap end in one of the mounting locations and is deformable to allow the strap to be selectively disengaged from the one of the mounting locations and moved to another of the mounting locations. 
     Another illustrative embodiment of the invention is directed to a snowboard binding including a base, at least one binding strap, and at least two strap mounting features supported by the base. The strap mounting features are adapted to mount the at least one binding strap to the base in at least two mounting locations. The strap mounting features and the binding strap are configured to allow the at least one binding strap to be selectively moved between the at least two strap mounting locations. A resilient shelf attached to the base tends to retain the binding strap in one of the mounting locations and is deformable to allow the strap to be selectively disengaged from the one of the mounting locations and moved to another of the mounting locations.

     DETAILED DESCRIPTION 
     Aspects of the invention are directed to an arrangement for adjusting the mounting location of an engagement member on a base, while the base is still attached to a substrate and without the need to apply external tools, e.g., a screwdriver, coin, wrench, etc. The system has particular application to a binding having one or more engagement members, such as a strap, for securing an object, such as a boot or foot, to a gliding implement or other substrate, and to a sport shoe or a boot including one or more engagement members for securing footwear components to improve performance properties such as heel hold down, for example, when the engagement member extends across the tongue or vamp of the sport shoe or boot. In certain embodiments, the mounting arrangement is completely internal to the base and cannot be, and need not be, directly accessed while the base is mounted to a substrate. In the latter arrangements, in particular, one of the engagement members or the base may be manipulated to disengage the engagement member from a mounting location. 
     For ease of understanding, and without limiting the scope of the invention, the inventive arrangement for tool free adjustment of the mounting location of an engagement member to which this patent is addressed is disclosed below particularly in connection with a snowboard binding that is used to secure a rider&#39;s boot to a snowboard. It should be appreciated, however, that the inventive engagement member repositioning system may be incorporated in a foot or boot binding device that may be mounted to substrates that are not designed specifically for gliding or other sports applications, and in a binding device that is employed to restrain objects other than a foot or boot. 
     The embodiment illustrated in FIG. 3 is a snowboard binding  40  arranged with a toe strap  42  and an ankle strap  44  for securing a rider&#39;s boot to a snowboard. A mounting location on the baseplate  46  for each of the toe strap  42  and the ankle strap  44  may be changed by the rider without using tools (i.e., “tool free”) and while the binding is mounted to the snowboard (i.e., “on board”), allowing the rider to select an appropriate setting suited to a particular style of riding or to a desired comfort or fit of the boot in the binding. Although the illustrated binding has two straps each of which is arranged for tool free, on board adjustment of the strap mounting location, the invention is not limited to a dual strap arrangement. Rather, the invention encompasses a binding having any number of straps that are constructed and arranged to allow relocation of the strap mounting without requiring the use of external tools and without having to remove the binding from the snowboard to free the strap from the mounting location. Thus, a binding with only a toe strap or an ankle strap, or a binding with a toe strap, an ankle strap and a shin strap are contemplated as are other binding constructions that employ different strap arrangements not expressly mentioned here. Further, the invention contemplates a binding having two or more straps where one or more, but not all, of the straps are arranged for tool free, on board adjustment. That is, some of the straps may require use of a screwdriver and/or a wrench, or other tool, to loosen and then to retighten fastening hardware to permit adjustment of the mounting location of the strap along the binding, but that arrangement is still within the scope of aspects of the invention so long as at least one strap is configured for tool free, on-board adjustment. Alternatively, the binding may include strapless engagement members in addition to one or more straps that are configured for tool free, on board mounting location adjustment. 
     The snowboard binding shown in FIG. 3 includes a baseplate  46  adapted to receive a snowboard boot, the base  46  having a floor  48 , a pair of opposed sidewalls  50  and a heel hoop  52 . A slot  54  extending within the sidewall  50  near the front or toe end of the binding  40  is sized to receive a mounting end of a strap  42  that will secure a front portion of a boot  14  to the snowboard  1 . By mounting the strap within the slot  54  rather than to the outside of the baseplate sidewall  50 , as in many conventional strap binding designs, the straps  42  and  44  are brought closer to a rider&#39;s boot. Such intimate foot wrap helps to eliminate a lag in response time by the board when the rider leans her boot into the binding straps  42  and  44 . The slot  54  includes two or more locking members  56 , illustrated in FIG. 4, which may be in the form of catches or recesses as shown, that are adapted to mate with a complementary locking member  58  on the strap. The strap carried locking member  58  in the illustrated embodiment is a boss or rod, that extends from one or both sides of the strap  42 , and which is captured by the locking member  56  in the slot  54 , e.g., the catch or a pair of opposed catches in the slot  54 . The length of the locking member  58  combined with the thickness of the strap portion  42  from which it projects is larger than the opening at the top of the slot  54 , preventing the strap  42  from pulling out of the baseplate  46 . In the illustrated embodiment, the mounting end of the strap  42  is just slightly thinner than the slot  54  opening so that the added thickness of the projecting locking member  58  is adequate to retain the mounting strap within the slot  54 . 
     The locking member  58  carried by the strap  42  may be molded integral with the strap or may be a separate component that is attached to the strap. In one embodiment, the mounting end of the strap  42  includes an opening into which a barrel shaped insert is snap fitted, with the ends of the barrel projecting outwardly from both sides of the strap  42 . Ridges running around the margins of the barrel insert are wider than the opening through the strap preventing the insert from falling out. The reduced diameter intermediate section extending between the annular ridges is slightly smaller than the opening in the strap  42  in which it lies, allowing pivoting of the strap  42  relative to the baseplate  46 . The locking member  58  carried by the strap may be formed of the same material as the strap or of a different material, with each of plastic, rubber, other elastomers and metal being suitable. The locking member  58  may be cylindrically shaped although other shapes are contemplated and the invention is not limited to the illustrated locking member  58  as would be understood by one of skill in the art. For example, the strap  42  may carry two or more locking members  58 . 
     The two or more locking members  56  for restraining the strap locking member  58  may have any shape that is compatible with the locking member  58  carried by the strap, such as a hollow half cylinder when the strap carried locking member  58  is a cylindrical shaped boss. The locking members  58  may be formed in the sidewall  50 , such as by molding, or may be contained in a separate structure that is fitted to the sidewall  50 . The locking members  58  may be arranged on only one side of a wall of the slot  54  or respective ones of opposed pairs of locking members  58  may be provided on each side of the slot  54 . Various other arrangements within the sidewall slot  54  for capturing a radially extending locking member on the strap, or other mateable locking member  58  carried by the strap, are envisioned. Without limiting the arrangements for releasably securing the strap carried locking member  58 , it also is proposed to arrange the slotwall locking member  56  for frictional engagement of the rod, boss, opening or other locking member, such as by using opposed ribs extending along the slotwall and which may be tapered inwardly towards the opening at the top of the slot  54  so that the locking member  58  is likely to become more tightly wedged or otherwise engaged as it is drawn upwardly in the slot  54 . 
     Also contemplated is a locking shelf projecting from one or both sides of the mounting portion of the strap that cooperates with a compatible shelf provided along one or both sides of the sidewall defining the slot  54 . The shelf on the strap may be smaller than the shelf within the slot wall to allow for various mounting locations of the strap. The shelf provided in the slotwall may be continuous or may include two or more spaced shelves. Other cooperative locking member arrangements may be implemented as would be apparent to one of skill in the art. As should be appreciated by the ordinary practitioner, the location of the complementary locking members may be reversed. Referring to the embodiment illustrated, for example, two or more bosses could be presented along a side of the slotwall, with a catch extending outwardly from a side of the mounting end of the strap. 
     The complementary strap locking member  58  and slotwall carried locking member  56  may be configured with a junction to allow pivoting of the strap relative to the baseplate  46 , so that the strap can rotate back and forth in response to forces induced on the strap as the rider flexes and turns her boot into the main body of the strap, as occurs frequently during a run down a slope or in a half pipe. In the embodiment shown, the locking member  58  has a round profile established by its cylindrical shape that is pivotable about the curved surface of the locking member  56  in the sidewall slot  54 . Other configurations of mateable locking members that allow relative pivoting while engaged also are contemplated as would be appreciated by those of skill in the art. 
     The mounting end of the strap  42  may be formed as a living hinge  60 ; that is, the bottom section of the strap  42  will temporarily compress or collapse, without permanently deforming, under the influence of an axial force along the strap in the direction of the mounting end, such as occurs when a rider grasps the strap and presses it against the baseplate  46  or snowboard  1 . Urging an end of the strap against the bearing snowboard surface  62  in the case of the toe strap  42 , or a bearing ledge  112  in the case of the ankle strap  44  described in more detail below, draws the strap carried locking member  58  away from the complementary locking member  56  in the baseplate sidewall  50 . With the strap mounted locking member  58  in the retracted position and the living hinge  60  still in a compressed mode, the strap  42  or  44  may be moved, such as by sliding, until the locking member  58  is repositioned relative to another mateable locking member  56  in the slot  54 . Upon release of the strap  42  or  44  by the rider, the living hinge  60  will revert to its prior expanded shape, securing the locking member  58  to its counterpart so that the strap is positioned in a new mounting location. 
     As shown, the living hinge  60  includes a thin end wall separated from a more substantial portion of the strap  42  by an opening or relief. Although a complete through opening is illustrated, a living hinge affect also may be provided by a partially recessed region at the end of the strap. Alternatively, the living hinge  60  may be provided by forming indentations or grooves in the surface of the mounting end of the strap, such as accordion or corrugated type impressions. In other embodiments, a more compressive or springy material may be included at some portion of the end of the strap, such as in all or at least a portion of the mounting region of the strap, e.g., between the locking member  58  and the mounting end of the strap, to cause the strap to collapse as an axial load is applied along the strap and against a bearing surface. Reference to the mounting end of the strap refers to any portion of the strap that interfaces with the baseplate  46  or other bearing surface, and is not limited to the portion of the strap between the locking member  58  and the very tip of the strap. The form of the living hinge  60  is not limited by the invention and will include other constructions in addition to those described here as would be apparent to those of skill in the art. Further, the living hinge affect could be constructed in the slotwall rather than in the strap so that selective compression of a portion of the slotwall would retract the slotwall mounted locking member  56  disengaging it from its mate on the strap. Once the strap is repositioned with its locking member  58  above a desired slotwall locking member, the baseplate section may be released allowing the slotwall locking member  56  to engage the strap locking member  58  in a new mounting location. 
     The base of the strap  42  may be rounded or curved, or otherwise configured to focus the compressive force on the living hinge region. Further, the strap base may be wider than the body of the strap to reduce the load required to actuate the hinge  60 . A rounded end may facilitate pivoting of the strap relative to the bearing surface, whether the bearing surface is the snowboard  1  as in the case of the toe strap illustrated in FIG. 4, or the bearing floor  112  as in the case of the ankle strap shown in FIG.  4 . Alternatively, the bearing surface may be provided with a recess or indentation that provides clearance for the mounting end to freely pivot. A particular shape of the mounting end of the strap is not essential for tool free, on board strap mounting location adjustment and a squared off end as well as other configurations also are envisioned. 
     The bottom of the sidewall slot  54  for mounting the toe strap  42  may remain open, as illustrated in FIG. 4, so that the mounting end of the strap will lie flush with, or be slightly compressed against, the snowboard surface  62  when the baseplate  46  is mounted to the snowboard  1 . However, the strap  42  could be shortened so that the mounting end does not contact the bearing surface, yet the strap  42  could be moved between mounting locations and the binding would still ably secure a boot when the strap  42  is tightened down regardless of the strap mounting location. For example, the slot  54  may be tapered so that a top end of the slot  54  is more narrow than a bottom end. This tapering would allow the strap to move freely when moved toward the bottom of the slot  54 , but have a tight interference fit with the slot  54  sidewalls when fully engaged. Unwanted disengagement may also be prevented by positioning a manually activated gate or other obstruction in the slot  54 , such as a flexible wall that may be moved aside or bent over by a rider moving the strap from one mounting location to another, to prevent unintentional movement of the strap. In another embodiment, the slot  54  may include a single elongated recess, e.g., in the form of a channel, along which the strap can be positioned. Once the strap is positioned at a desired location in the slot  54 , a plug or plugs can be inserted into the slot  54  to prevent movement of the strap to another mounting location. The strap may be moved in the slot  54  by removing the plug(s), moving the strap to another location, and replacing the plug(s). The plug(s) may be inserted downwardly into the slot  54 , or through a hole in the sidewall  50  perpendicular to the slot  54 . However, by arranging the strap end so that it is in constant contact with the bearing surface, slop or jiggling of the strap may be avoided which might otherwise adversely affect the feel or performance of the binding and might detract from the appearance of the binding when the straps are not fastened down about a rider&#39;s boots. Alternatively, the bottom of the slot for mounting the toe strap  42  could be closed or otherwise include its own bearing surface in an arrangement comparable to the bearing surface construction employed in the sidewall slot for the ankle strap  44  discussed below. 
     As shown in FIGS. 4 and 5, the sidewall slot  110  for mounting the ankle strap  44  is elevated significantly from the surface of the snowboard  1  making it impractical to use the top of the snowboard  1  as the bearing surface against which the strap end may be urged to actuate the living hinge  119 . Instead, the sidewall slot  110  includes a floor or rail  112 , or other arrangement, which acts as the bearing surface. To provide direct access to the slot  110  for insertion of the strap  44 , the sidewall may be formed of separate pieces which are united by releasable fasteners  114 , or other mechanisms, such as bonding or welding, after the strap end is placed in a desired position. When assembled, the separate sidewall sections may combine to form the floor  112  against which the bottom of the strap end is seated. Alternately, the sidewall  50  may have a window formed in the sidewall  50  that exposes at least a portion of the slot  110  through which the strap  44  may be engaged with the binding, or the slot  110  may be formed to extend through the bottom of the elevated portion of the sidewall  50 , e.g., so that the strap  44  may be inserted through the bottom of the slot  110 . If the slot  110  is formed through the bottom of the sidewall  50 , the bottom of the slot  110  may be closed by a door or other member, e.g., a member that is engaged with the sidewall  50  by an interference fit in the slot  54 , fasteners, etc. to form the floor  112 . The sidewall sections also may form two or more catches or other locking members  116  that cooperate with the locking member  118  on the strap  44  to fix the strap in multiple mounting locations. The bearing surface may be formed of a stiff material to cause compression of the living hinge  119  as the strap is urged against the bearing surface. Alternately, the floor  112  (bearing surface) may include a resilient and/or compressible material as illustrated in FIGS. 6 and 7. In this embodiment, the floor  112  may compress when the strap end is forced against it, allowing the strap  44  to travel far enough in the direction of the bearing floor  112  to disengage the strap carried locking member  118  from the slotwall locking member  116 . Where the floor  112  is resilient, the strap  44  may not include a living hinge  119  or other resilient member and instead the bearing surface may urge the complementary locking members together. 
     Other arrangements of tool free, on board adjustment of the mounting location of a binding strap are illustrated in FIGS. 8-13. FIGS. 8 and 9 show an embodiment in which the sidewall includes a mount  70  with two parallel columns of teeth  72  within a sidewall slot  74  and further includes a central opening through which a portion of a strap  76  extends. A lower part  78  of the strap is provided with two parallel racks of teeth  80  that are engageable with a segment of the columns of teeth  72  in the slotwall. The strap  76  is formed at its mounting end with a living hinge  82  that resiliently biases against the bearing surface  84 , urging the racks of teeth  80  into complementary locking with an aligned section of teeth  72  on the mount  70 . Pressing the strap  76  against the bearing surface  84  compresses the living hinge  82  so that the racks of teeth  80  are retracted from their mates in the mount  70  and, once the opposing teeth are separate, the strap  76  may be slid in either direction until a new mounting location is selected. Upon release of the strap  76 , the living hinge  82  springs open, uniting the strap carried teeth  80  with a different segment of counterpart teeth  72  on the mount  70 , securing the strap  76  in the new mounting location. The mount  70  may be molded integral with or fitted to the wall defining the slot  74 , or a separate component  86 , such as a molded plastic or metal formed insert, may be fixed to an opening in the baseplate sidewall  50  as illustrated in FIG.  8 . Other arrangements for implementing the toothed mount  70  are contemplated as should be apparent to one of skill in the art. 
     Although the complementary locking members portrayed in FIGS. 8-9 employ pairs of teeth, a single array of teeth  100  may be employed on the mount and on the rack as shown in FIG.  10 . While the teeth are arranged linearly in the illustrated embodiments, non-linear patterns also may be used as would be apparent to one of skill in the art. Although pointed angular teeth have been drawn, other interlocking shapes and arrangements are contemplated and the particular interlocks illustrated, in this case teeth, should not be understood to limit the scope of the invention. The mounting end of the strap including the teeth or other locking configuration may be articulated  102  to the body of the strap to ensure a range of motion of the strap body in response to movements of the boot by the rider. In the FIG. 10 embodiment, the mounting end of the strap includes an eyelet  104  which is registered with a clevis type junction  106  in the strap body, and a bolt and nut, rivet or other fastener system  108  is applied to join the two sections together in articulated fashion. 
     In FIGS. 11-13, the rack of teeth on the strap is replaced by a boot  88  formed, for example, from a rubber sheet that grabs the locking teeth  89  in the sidewall slot, preventing unintentional displacement of the strap  92  from the mounting location. A resilient member  90 , such as a living hinge, is connected to the strap  92  and seated against the mount  93  and urges the strap in a direction away from the mount  93 . A lower section of the strap  92 , positioned below the mount, includes the boot  88  although other engagement members could be employed. In the expanded or natural configuration of the biasing member  90 , the boot  88  grabs the teeth  89  securing the strap  92  in a particular mounting location. Movement of the strap  92  towards the baseplate with sufficient force will overcome the bias of the resilient member  90 , separating the boot  88  and teeth  89  a sufficient distance so that the strap  92  may be moved until located in a new mounting location. Release of the strap  92  by the rider removes the load on the member  90  which then unfurls to its natural uncompressed shape, drawing the boot  88  again into engagement with the mount carried teeth  89 . In the embodiment illustrated in FIGS. 11-13, the teeth  89  are supported by a mount or fitting  93  that is inserted into the slot and then fastened to the sidewall with appropriate hardware or by welding, bonding or other techniques familiar to one of skill in the art. 
     In the embodiments described above, the strap(s) may be a single continuous member that extends from one side of the baseplate  46  to the other or may consist of two or more separate sections that combine to span the baseplate  46 . Where two or more strap sections are joined together to secure a rider&#39;s foot within the binding  40  and which are then separated to free the boot from the binding  40 , one of the strap sections may be a ratchet strap having a surface portion arranged with teeth or serrations while the other strap section may be a boot engagement strap, typically longer than the ratchet strap and including a body portion that contacts the boot and which may be padded or otherwise specially configured for relieving and/or distributing pressure on sensitive areas of the foot. The ratchet strap may include a rounded narrower tip to facilitate introduction into a buckle carried on the boot engagement strap, such as a ratchet tongue. The boot engagement strap may include a fastener for releasably securing the ratchet strap, such as a buckle having a pawl for engaging the toothed surface. Advancing the ratchet strap through the buckle incrementally tightens the strap sections around the rider&#39;s boot, while the pawl prevents unintended loosening of the united strap components. The buckle may include a lever to help drive the toothed strap through the pawl. A ratchet buckle that is particularly suited for implementation with the strap used in aspects of the invention is a Slap Ratchet® buckle provided in various Burton Snowboards binding models and which is described in U.S. Pat. No. 5,745,959, which is assigned to Burton Snowboards, the owner of the present application. Other buckle configurations and other fastening arrangements for releasably joining two binding strap sections also are contemplated as would be apparent to one of skill in the art. The mounting location of the boot engagement strap, like the ratchet strap, may be arranged for tool free repositioning while the binding is secured to the board, with the mounting end of the boot engagement strap and the corresponding slotwall having a comparable construction to the ratchet strap and slotwall discussed within this specification. 
     The length of a strap or of individual strap sections may be adjustable; for example, a strap section may consist of a first member that is telescopically mounted to a second member and may include hardware or other fastening mechanism(s) to fix the two members at a desired overall strap section length. The arrangement of the body of the strap for securing a rider&#39;s boot is not limited by the present invention. Thus, adjustable length straps that are not configured telescopically also are within the inventive arrangement as are unvarying, single length straps. The body of the strap may include padding or cushioning to distribute pressure applied by the strap. Relief also may be provided by one or more recesses or openings in the strap body that direct forces away from particularly sensitive areas of the foot against which the strap is drawn. For example, where the strap is an ankle strap, a central portion of the body may have a reduced thickness, be formed of a compressible material, or may include one or more slotted sections to reduce rider discomfort. At least a body portion of the strap is conformable to a portion of the boot surface as the strap is tightened down. The strap, or specific strap sections, may be bendable into a substantially U-shape or other configuration that tracks the contours of the rider&#39;s boot about which it is tightened. Upon release of the strap or disengagement of the strap sections, the strap may spring partially or fully open to provide a path for removal of the boot from the binding. The strap sections may be stiffer at the mounting end and more flexible towards the opposite end to encourage conformability to the boot surface as the strap is tightened down. Suitable strap forming materials include molded, extruded or cast plastics, natural or synthetic fabrics, metal strips, and a combination of any of the above materials. 
     The snowboard binding illustrated includes a baseplate having a floor, sidewalls and a heel hoop. Plateless binding bases also are contemplated, which eliminate the floor so that a rider&#39;s boot seats directly on the snowboard surface. Also contemplated is an arrangement where the straps are mounted directly to the snowboard, such as in slots provided in the snowboard surface. The binding may include a highback that coacts with a heel hoop for providing heelside support and heel edge control. A forward lean adjuster may also be provided to set the highback at a preselected forward lean angle relative to the board. A hold-down disc may be used to secure the baseplate to the snowboard in any one of numerous stance angles. Various other features may be implemented to enhance riding performance. Although the binding described here is constructed to secure a snowboard rider&#39;s boot, a binding incorporating the inventive tool free system for adjusting the mounting location of an engagement member may be configured to restrain other objects as well, with the identity of the element contained by the binding not being an essential component of the invention. 
     The arrangement for mounting a strap for tool free adjustment also may be employed in a sports shoe or boot, particularly a hybrid boot or soft boot compatible with a step-in snowboard binding. Considerable lifting forces are generated at the heel of a snowboarder during riding. To maximize rider control, it is desirable to prevent the rider&#39;s foot, particularly the heel, from lifting off the bottom of the boot. In the “tray” type binding discussed earlier, the ankle strap can be tightened down over the boot to prevent heel lift. However, with a strapless soft boot step-in binding, there is no boot engagement member on the binding for limiting heel lift. Although the laces of the snowboard boot are available to resist lifting forces, the laces alone are often not sufficient to provide desired restraint. Consequently, many soft boots adapted for use with a step-in binding employ an ankle strap in addition to a lacing system. The ankle strap, similar to the ankle strap described above in connection with a snowboard binding, includes a ratchet strap and a boot engagement strap provided with a ratchet buckle. Each of the two strap components has a fixed end that is attached to one side of the boot, with the respective free ends being joined together. 
     The two strap components may be arranged on the boot so that the ankle strap may be relocated among different mounting locations about the front of the boot without the use of tools. A mount for each ankle strap section would include a base or a pedestal that is adhered, stitched or otherwise secured to the boot. Within each base would be a slotwall or equivalent feature including two or more locking members that are mateable with a locking member at a mounting end of either the ratchet strap or boot engagement member. A living hinge construction may be provided at the mounting end of the strap or, alternatively, a floor of the slotwall may be compressible and/or resilient, as discussed above in connection with a binding, such that urging of a strap section towards the floor of the slotwall causes the locking member to retract from the slotwall locking member, freeing the strap for relocation into another mounting location. The various permutations of locking members, strap mounting ends, and slotwalls disclosed above in connection with the binding embodiments apply here as well. 
     A representative method of adjusting the mounting location of an engagement member within a base will now be described in connection with a snowboard binding. However, the same approach will apply to a binding used on other gliding implements, to a binding for securing an object other than a boot or foot, and to a base and engagement member that is not incorporated into a binding type device. A binding is provided including a baseplate having a sidewall with a pair of toe strap slots and ankle strap slots and ratchet tongue sections received in one of each of the toe strap and ankle strap slots and boot engagement sections with buckles received in the other of each of the toe strap and ankle strap slots. The binding is mounted to a board by threading screws through apertures in a hold down disc into insert fasteners in the board. The toe straps and ankle straps are provided in either a first mounting location or a second mounting location, and the two straps need not be provided in the same mounting location (i.e., the toe strap could be positioned in the first location while the ankle strap is arranged in the second location). To change the mounting location of either strap, a rider grasps a portion of one of the strap sections, for example, the ratchet tongue extending outwardly from the baseplate, and pushes it into the baseplate so that the mounting end of the strap collapses and draws the locking boss out of the catch where it previously had been engaged. With the mounting end still collapsed, the strap is moved by the rider to the second mounting location. When the rider releases hold of the ratchet tongue, the collapsed mounting end reverts to its normal shape urging the locking boss into engagement with the locking catch at the second mounting location. The rider then proceeds in a similar fashion with the boot engagement strap associated with the just adjusted ratchet tongue. If desired, the other strap sections may be repositioned as well. 
     Having described several embodiments of the invention in detail, various modifications and improvements will readily occur to those skilled in the art. Such modifications and improvements are intended to be within the spirit and scope of the invention. For example, one or both sides of a slotwall may include a series of spaced holes that are mateable with a spring mounted ball or other interlock supported in a mounting end of a strap section. Depressing the ball allows the strap to disengage from the slotwall, and the strap may then be relocated so that the ball pops into an opening at another mounting location. Thus, the binding may include any type of detent that allows a strap to be moved from one mounting location to another by the tool-free application of a force on one or more resilient members, such as a living hinge on the strap mounting end. Accordingly, the foregoing description is by way of example only and is not intended as limiting. The invention is limited only as defined by the following claims and their equivalents.
