Definitions
- the disclosure relates to footwear, particularly the specialized type of footwear used in conjunction with an external appliance such as a snowboard, wakeboard or other sports apparatus.
- the foot is desirably protected from impact, the highly mobile function of the foot is desirably supported to some extent while still allowing desired movements, and the footwear often desirably provides engagement surfaces for the attachment of appliances such as snowboard bindings and boards.
- the materials used for the boot will be selected to achieve a desired degree of deformation to allow such function through bending or wrinkling of the structure. This type of flexation, however, tends to be unpredictable, inconsistent, temperature dependent and even uncomfortable if the shape of the boot deforms in a way that impacts the foot inside.
- a footwear device such as a boot, that allows mechanical flexation of the boot structure through the de-coupling of selected, discontinuous panels. While such panels may remain connected by lightweight and ultra-flexible bridging materials for the purpose of sealing out moisture or contaminants, these bridging materials do not necessarily provide significant structural support. Rather, the primary support panels are allowed to move with substantial independence from one another in response to outside loads. By localizing these articulating panels and managing their relative ranges of motion, each area of the boot can be allowed defined flexibility, with minimal impact of one area's characteristics upon another. Adjacent panels may be placed next to each other in the same approximate plane, or may be overlapping with some degree of fixation between them.
- articulating panels may be located in various areas of the boot.
- the forefoot region may be allowed a certain amount of dorsi- and plantar-flexion to facilitate walking.
- the ankle area of the main boot body may be allowed articulation in various directions.
- tongue An additional important component in many footwear designs is the tongue, which is normally formed into a three dimensional curve—concave over the top of the foot and in front of the lower leg, plus L shaped between instep and shin area. Considering that appliances are often attached to the boot by means of straps which bear against the tongue area, it is important for this element to offer certain stiffness and pressure distribution characteristics for the protection of the foot.
- the disclosed features present a means by which the tongue can provide this type of protection through the use of more rigid materials, while retaining the ability of the foot to function through a natural range, avoiding unwanted deformation that is inherent in the design of a continuous panel.
- Combining multiple elements of the design to allow articulation has an exemplary benefit of providing localized support and protection where desired, while still allowing a relatively free range of motion to the user. Secondarily, this range of motion occurs without the need for kinking or other undesirable flexation of panels located adjacent to the natural articulation points of the foot and ankle. The result for the user is secure and consistent fit throughout whatever range of motion is designed into the boot.

Further, molded overlay and underlay panels can be engineered to maintain the desired flexing characteristics of the panels, including the ability to form a given panel with multiple flexing characteristics in discrete areas or in certain directions. The panels do not need to be isotropic in nature.

For example, if a strap is to bear against a particular region, that region can be manufactured of a material that protects the foot against the pressure points of the strap. On the other hand, a region that does not bear a strap can be made of a soft material that emphasizes comfort. In this manner, the regions can be sized, shaped, and manufactured to provide localized characteristics to different areas of the tongue.

Abstract
A boot includes an upper formed of articulating panels that permit portions of the boot to move in substantial independence from one another in response to loads experienced by the boot. The boot generally comprises a sports boot that is positioned around a wearer's foot for coupling to an external appliance, such as a snowboard, wakeboard, skating appliance (such as a blade or wheels), or any other appliance.
Description
- This application is a continuation of U.S. patent application Ser. No. 13/032,547, entitled “ARTICULATING FOOTWEAR FOR SPORTS ACTIVITY” and filed Feb. 22, 2011, which is a continuation of U.S. patent application Ser. No. 11/622,421, entitled “ARTICULATING FOOTWEAR FOR SPORTS ACTIVITY” and filed Jan. 11, 2007, now U.S. Pat. No. 7,891,119, which in turn claims priority to U.S. Provisional Patent Application Ser. No. 60/758,952, entitled “ARTICULATING FOOTWEAR FOR SPORTS ACTIVITY,” filed Jan. 13, 2006, which are incorporated herein by reference in their entireties.
- The disclosure relates to footwear, particularly the specialized type of footwear used in conjunction with an external appliance such as a snowboard, wakeboard or other sports apparatus.
- There are many desirable characteristics for the design of footwear used in sports applications. The foot is desirably protected from impact, the highly mobile function of the foot is desirably supported to some extent while still allowing desired movements, and the footwear often desirably provides engagement surfaces for the attachment of appliances such as snowboard bindings and boards.
- The three dimensional nature of the human foot necessitates that such footwear be formed into a complex shape. This is often done at the manufacturing level by stitching flat panels together or molding three dimensional panels and joining them into an enclosing form. This yields an outer structure for the piece of footwear that is more or less continuous and unified in nature.
- When flexible materials such as leather and synthetic sheets are thus formed into three dimensional shapes, the structure becomes considerably more rigid. For example, a normal magazine, very flexible in nature, when rolled into a tube becomes rigid and unyielding. When a boot is closed snuggly around the foot, the same thing happens: flexible panels take on a stiffer and more supportive structure by the nature of their shaping.
- In some areas of a boot this can be a desirable effect, providing enhanced support and protection for the foot. However, many activities require the foot to move throughout a certain range of motion in order for the user to maintain dynamic balance, steer the appliance, control speed or simply maneuver at will.
- Typically, the materials used for the boot will be selected to achieve a desired degree of deformation to allow such function through bending or wrinkling of the structure. This type of flexation, however, tends to be unpredictable, inconsistent, temperature dependent and even uncomfortable if the shape of the boot deforms in a way that impacts the foot inside.
- Disclosed is a footwear device, such as a boot, that allows mechanical flexation of the boot structure through the de-coupling of selected, discontinuous panels. While such panels may remain connected by lightweight and ultra-flexible bridging materials for the purpose of sealing out moisture or contaminants, these bridging materials do not necessarily provide significant structural support. Rather, the primary support panels are allowed to move with substantial independence from one another in response to outside loads. By localizing these articulating panels and managing their relative ranges of motion, each area of the boot can be allowed defined flexibility, with minimal impact of one area's characteristics upon another. Adjacent panels may be placed next to each other in the same approximate plane, or may be overlapping with some degree of fixation between them.
- Additionally, by allowing articulation between components, individual panels can be fabricated with increased stiffness for improved support and protection. Designs which rely on deformation of fixed panels for flex are limited in the degree of support and protection by the need to consider overall function of the footwear structure. Often a boot that is stiff enough for protection is too rigid for proper function. The converse is also true in that soft boots that flex freely do a generally poor job of protecting the foot and providing needed support.
- As shown in the accompanying drawings, articulating panels may be located in various areas of the boot. In some embodiments, the forefoot region may be allowed a certain amount of dorsi- and plantar-flexion to facilitate walking. The ankle area of the main boot body may be allowed articulation in various directions.
- An additional important component in many footwear designs is the tongue, which is normally formed into a three dimensional curve—concave over the top of the foot and in front of the lower leg, plus L shaped between instep and shin area. Considering that appliances are often attached to the boot by means of straps which bear against the tongue area, it is important for this element to offer certain stiffness and pressure distribution characteristics for the protection of the foot. The disclosed features present a means by which the tongue can provide this type of protection through the use of more rigid materials, while retaining the ability of the foot to function through a natural range, avoiding unwanted deformation that is inherent in the design of a continuous panel.
- Combining multiple elements of the design to allow articulation has an exemplary benefit of providing localized support and protection where desired, while still allowing a relatively free range of motion to the user. Secondarily, this range of motion occurs without the need for kinking or other undesirable flexation of panels located adjacent to the natural articulation points of the foot and ankle. The result for the user is secure and consistent fit throughout whatever range of motion is designed into the boot.
- The details of one or more implementations are set forth in the accompanying drawings and the description below. Further features, aspects, and advantages will become apparent from the description, the drawings, and the claims.

FIG. 1 shows a lateral side view of an exemplary embodiment of a boot. -
FIG. 2 shows a lateral side view of the boot ofFIG. 1 revealing connections of underlay panels. -
FIG. 3 shows a lateral side view of another embodiment of a boot. -
FIG. 4 shows a perspective view of an articulating tongue that can be incorporated into any of the boot embodiments described herein. -
FIG. 1 shows a side view of an exemplary embodiment of aboot 100 with an upper formed of articulating panels that permit portions of the boot to move in substantial independence from one another in response to loads experienced by the boot. The boot generally comprises a sports boot that is positioned around a wearer's foot for coupling to an external appliance, such as a snowboard, wakeboard, skating appliance (such as a blade or wheels), or any other appliance. - The
boot 100 generally includes anoutsole 105 and an upper 110 mounted above theoutsole 105. The upper 105 includes a pair of closure flaps that at least partially cover atongue 110 positioned along an insole region and a front region of the boot in a well-known manner. Alacing system 115 includes alace 117 that is threaded through the upper 110 and attached at opposite ends to atightening mechanism 120. It should be appreciated that theboot 100 could be used with various types of lacing systems and need not include thetightening mechanism 120. - The upper 110 surrounds a person's foot and is at least partially formed of two or more panels that can move relative to one another to permit the upper 110 to deform in response to loads, such as loads generated during various movements of the foot and/or leg. The panels can be shaped and positioned in a predetermined manner to permit localized ranges of motion of the panels relative to one another. Each panel can have structural characteristics, such as flexibility and stiffness that are particularly suited for the location of the panel on the boot. Because the panels can move relative to one another, the structural characteristics of one panel have minimal or no effect on the structural characteristics of an adjacent panel.
- With reference still to
FIG. 1 , theboot 100 includes overlay panels and underlay panels. The overlay panels at least partially cover or overlay a portion of the underlay panels and have a range of motion relative to the underlay panels. The overlay panels are sized such that portions of the underlay panels are exposed. It should be appreciated that the quantity and relative positions of the overlay and underlay panels can vary to suit desired articulation characteristics for theboot 100. - One or more of the underlay panels can be manufactured of a material that has increased flexibility relative to the overlay panels such that the underlay panels can articulate. In addition, the underlay panels are configured in a manner that permits relative movement between of the underlay panels relative to one another and relative to the overlay panels, as described below. The overlay panels can also be configured to have various levels of stiffness and relative movement to enable localized articulation and stiffness levels that meet desired criteria.
- In the exemplary embodiment of
FIG. 1 , theboot 100 includes aside overlay panel 125 that is generally positioned along a lower side and toe region of the boot and anupper overlay panel 130 that is generally positioned along an upper side region of the boot such as in the general vicinity of the ankle or lower leg.FIG. 1 only shows one side of theboot 100. It should be appreciated that thepanels panels boot 100. - The
boot 100 also includesfront underlay panel 135, aside underlay panel 140, and anupper underlay panel 145. Thefront underlay panel 135 is generally positioned in the toe region of the boot forward of theoverlay panel 125, although a portion of theoverlay panel 125 extends along a forward edge of the toe region. Theside underlay panel 140 is positioned along a side region of the boot in-between theoverlay panels upper underlay panel 145 is positioned along an upper region of the boot upward of theoverlay panel 145. As mentioned, at least a portion of theunderlay panels 145 extend beneath the overlay panels and in a manner that permits relative motion between the overlay and underlay panels. Thus, the portions of the underlay panels that are positioned beneath the overlay panels are not visible inFIG. 1 . -
FIG. 2 shows a side view of theboot 100 and shows how the underlay panels are connected to one another. In an exemplary embodiment, the underlay panels are connected via seams positioned beneath the overlay panels. Theunderlay panels seam line 210 that is positioned on the side of theboot 100 beneath theoverlay panel 125. Theseam line 210 extends upwardly from the edge of the sole 105 to a cut-out 215 positioned in-between theunderlay panels underlay panels - In a similar manner, the
underlay panels seam line 220 located beneath theoverlay panel 130. Theseam line 220 can wrap around the rear of the boot to the opposite side of the boot from that shown inFIG. 2 or it can follow an alternate pathway. Theseam line 215 has a forward edge that terminates at a cut-out 225 positioned in-between theunderlays underlay panels underlay panels - It should be appreciated that the described underlay and overlay panels may be reversed in such a way that the articulating panels are external while the “covering” panels are internal to help seal out moisture. It is also possible for there to be no separate underlay and overlay panels, with the various articulating panels thus comprising the entire body of the boot.
- In one embodiment, the cut-
outs 215 and 225 are empty spaces in that no material is positioned in-between the underlay panels in the region of the cut-outs. In another embodiment the cut-outs are filled with a bridge material that interconnects the respective underlay panels. The cut-out material can be a lightweight, flexible, material that does not necessarily provide structural support to the boot, but that provides protection against the environment, such as sealing against moisture or other contaminants entering the boot. - As mentioned, the cut-
outs 215 and 225 serve as regions of articulation or relative motion between the underlay panels. The cut-out 215 is positioned in the forefoot region of the boot and permits a range of motion between theunderlay panels underlay panels - For example, the
upper overlay panel 130 can be made of a stiffer material to provide strong support to the ankle region of the boot, while theunderlay panels - As mentioned, the overlay and underlay panels can each be made of a material of predetermined characteristics. The material of each overlay and underlay panel can be particularly selected to provide localized structural characteristics to particular region of the boot where the panel is located. Because the panels can move relative to one another, the structural characteristics of one panel do not necessarily affect the structural characteristics of an adjacent panel.
- The overlay and underlay panels can be manufactured of any of a variety of materials and pursuant to any of a variety of techniques. In one embodiment, at least a part of each panel is manufactured by molding. The three dimensional nature of the human foot and lower leg may require that the overlay and underlay panels be formed into complex shapes. Molding of the overlay and underlay panels allows for the construction of a comfortable upper that conforms to the shape of the rider's foot and leg. Further, molding the panels limits the weight of the boot because less material is used compared to, for example, cutting and stitching together flat panels into a three-dimensional shape. Further, molded overlay and underlay panels can be engineered to maintain the desired flexing characteristics of the panels, including the ability to form a given panel with multiple flexing characteristics in discrete areas or in certain directions. The panels do not need to be isotropic in nature.

FIG. 3 shows another embodiment of a boot, referred to asboot 300. In this embodiment, the upper is comprised of a lower region and an upper region that have a range of motion relative to one another. The upper region can be hinged relative to the lower region to permit relative movement therebetween or the upper region may be partially attached to the lower region, leaving a certain area unattached to allow for relative movement between the two regions. - With reference to
FIG. 3 , theboot 300 has an upper that includes alower region 310 generally positioned around the foot and lower ankle region of the boot. The upper also includes anupper region 315 that is generally positioned around the upper ankle and lower leg region of the boot. Theupper region 315 andlower region 310 meet one another along anattachment region 320. Theattachment line 320 comprises a region where thelower region 310 and theupper region 315 connect to one another. The attachment can be via stitching, riveting, through the use of a continuous piece of material, or through other attachment means. The upper and lower regions can also articulate or move relative to one another along anarticulation region 325. The upper and lower regions are not attached to one another along thearticulation region 325. Theupper region 315 can articulate or move independent of thelower region 310 along thearticulation region 325. - Thus, the
upper region 315 andlower region 310 are connected along theattachment region 320 at a frontward location of the boot and can articulate relative to one another along thearticulation region 325 at a backward location of the boot. This permits theupper region 315 to pivot relative to the lower region with respect to a relatively fixed portion of the structure that is positioned near the front of the boot. - The boot of
FIG. 3 can be particularly useful as a snowboard boot that is used with a snowboard binding having a rear highback that supports the rear of the boot. Such a binding is described in U.S. Pat. No. 5,918,897, which is incorporated herein by reference in its entirety. The rear highback provides support to the ankle region of the boot in backward lean, so there is no need for the boot itself to provide such support. Hence, the upper and lower regions are free at the rear of the boot thereby permitting relative movement in the rear. The free movement between the upper and lower regions at the rear of the boot permits the boot to articulate while not bulging outward at the lower part of the boot during forward flex. On the other hand, because the upper and lower regions of theboot 300 are fixed to one another at the front side, the boot provides some support at the front of the boot. -
FIG. 4 shows an articulatingtongue 400 that can be incorporated into any of the embodiments of the boots described herein. Thetongue 400 includes two or more distinct regions that are connected to one another along predetermined connection zones. The regions can move relative to one another and can each be manufactured of a material having desired structural characteristics specifically suited to the location of the region on the tongue. Thus, the tongue can have localized desired structural characteristics, such as stiffness and pressure distribution characteristics for protection of the foot, while the relative movement of the regions permits the underlying foot to function through a natural range of motion. The size, shape, and location of the connection zone for each region is selected to provide the tongue with the ability to comfortably conform to the shape of the foot while still providing stiffness and protection where needed. - In the embodiment of
FIG. 4 , thetongue 400 includes aninstep region 405, anintermediate region 410, and anupper region 415. Theinstep region 405 andintermediate region 410 are connected along aconnection zone 420 which may be located along a center line or any other axis which need not be symmetrically located with respect to the main axis of the tongue. Theintermediate region 410 andupper region 415 are connected along aconnection zone 425. Afront strip 430 is positioned on top of theregions - At the
connection zones -
Filler regions 435 are positioned between theregions tongue 400. However, thefiller regions 435 can be shaped and can be manufactured of a material to permit the tongue to properly seal around the instep of the foot, such as to prevent moisture or other contaminants from entering the boot. - Each region can be manufactured of a different material that provides desired structural characteristics to the particular region of the tongue where the region is located. For example, if a strap is to bear against a particular region, that region can be manufactured of a material that protects the foot against the pressure points of the strap. On the other hand, a region that does not bear a strap can be made of a soft material that emphasizes comfort. In this manner, the regions can be sized, shaped, and manufactured to provide localized characteristics to different areas of the tongue.
- Although embodiments of various methods and devices are described herein in detail with reference to certain versions, it should be appreciated that other versions, embodiments, methods of use, and combinations thereof are also possible. Therefore the spirit and scope of the disclosure should not be limited to the description of the embodiments contained herein.
