Likewise, a ski boot is designed to maximize a user's performance at a particular skiing activity.
- Boots generally include a shell, a compression system, and a sole.
- the shell and compression system operate to encase and support the foot and lower leg of a user.
- Various well-known shell and compression systems are utilized to allow users to insert and remove their feet in an open boot configuration and compress the shell around the foot in a closed boot configuration.
- the sole of a boot is disposed on the bottom surface of the shell.
- the sole is generally composed of a rubber or plastic material.
- the sole may consist of a single piece or multiple blocks. The stiffness and/or weight characteristics of the sole have an affect on the overall performance of the boot.
- the general activity of skiing comprises many subsets including but not limited to alpine touring, telemark, and downhill.
- Each subset of skiing generally corresponds to a unique system of specialized equipment.

- the binding interface surfaces for each block are positioned at different sagittal heights with respect to the shell to facilitate the interconnection with alternative binding coupling systems.
- a second embodiment of the present invention relates to a ski boot system including a shell, a block, and a modular coupling system.
- a third embodiment of the present invention relates to a method for modularly coupling alternative blocks to a shell on a ski boot so as to effectuate alternative binding interface surface sagittal positions without substantially effecting sagittal sole surface orientation.
- Embodiments of the present invention represent a significant advance in ski boot and boot binding interface technology.

- the single connection interface may only facilitate connection with compatible bindings.
- Conventional boot systems may also include a system for modularity that enables interchangeable blocks to be positioned on the bottom of the boot.
- these conventional modular systems affect the performance of the boot binding system by effecting the sagittal height and/or angle between the boot and the binding.
- Embodiments of the present invention overcome these limitations by providing a modular system that enables boot binding compatibility between a wide range of connection schemes by enabling a custom binding interface surface position.
- the system ensures that the spacing and orientation of the boot with respect to the binding will remain consistent by maintaining a constant sole surface position.

Abstract
Description
- FIELD OF THE INVENTION
- The present invention generally relates to a modular boot binding interface system. In particular, the invention relates to a ski boot system with a modular boot binding interface.
- .
- .
- BACKGROUND OF THE INVENTION
- A boot is a type of footwear that encases both the foot and a portion of the lower leg of a user. Boots are generally manufactured for a particular purpose or activity and therefore are designed to include characteristics consistent with the intended purpose. For example, a hiking boot is designed to support the ankle of a user while minimizing the overall weight. Likewise, a ski boot is designed to maximize a user's performance at a particular skiing activity.
- Boots generally include a shell, a compression system, and a sole. The shell and compression system operate to encase and support the foot and lower leg of a user. Various well-known shell and compression systems are utilized to allow users to insert and remove their feet in an open boot configuration and compress the shell around the foot in a closed boot configuration. The sole of a boot is disposed on the bottom surface of the shell. The sole is generally composed of a rubber or plastic material. The sole may consist of a single piece or multiple blocks. The stiffness and/or weight characteristics of the sole have an affect on the overall performance of the boot.
- The general activity of skiing comprises many subsets including but not limited to alpine touring, telemark, and downhill. Each subset of skiing generally corresponds to a unique system of specialized equipment. For example, the boot, ski, and binding systems used for telemark skiing are significantly different from those used for alpine touring. A skiing system may include standard types of boots, skis, and bindings. Each type of skiing also requires unique characteristics of a boot to achieve optimal performance. In addition, particular terrain and skier preference may require an even more specific set of performance characteristics. Boots for particular skiing activities must be compatible with the remainder of the system. For example, telemark skiing boots have generally been required to conform to the 75 mm standard to allow for compatibility with telemark type bindings.
- One of the problems with existing boot systems is their limited adaptability to a variety of systems, activities and/or user preferences. Most conventional skiing boots can be adjusted with the compression system to provide different degrees of compression between the shell and user's foot. This adjustment can be used to control a variety of characteristics. However, certain boot performance characteristics such as binding compatibility, sole flex, torsion, and weight cannot be adjusted with the compression system.
- Therefore, there is a need in the industry for a modular boot system that allows for multi-binding compatibility and the adjustment of certain sole related flexibility and weight characteristics without substantially affecting performance.
- SUMMARY OF THE INVENTION
- The present invention generally relates to a modular boot binding interface system. One embodiment of the present invention relates to a ski boot system with a modular binding interface. The system includes a shell encasing a user's foot and lower leg. A first and second block are interchangeably coupled to the shell below the base to effectuate alternative binding interfaces. The first and second blocks include a binding interface surface and a sole surface. The positioning and shape of the blocks with respect to the shell results in the binding interface surface extending distally from the toe region of the shell and the sole surface being the lowest surface on the boot system. The binding interface surfaces for each block are positioned at different sagittal heights with respect to the shell to facilitate the interconnection with alternative binding coupling systems. The sole surfaces for each block are positioned at substantially identical sagittal heights with respect to the shell to maintain optimum and consistent performance characteristics among different bindings. A second embodiment of the present invention relates to a ski boot system including a shell, a block, and a modular coupling system. A third embodiment of the present invention relates to a method for modularly coupling alternative blocks to a shell on a ski boot so as to effectuate alternative binding interface surface sagittal positions without substantially effecting sagittal sole surface orientation.
- Embodiments of the present invention represent a significant advance in ski boot and boot binding interface technology. Conventional boots generally include a single connection interface such as a duckbill toe platform for coupling with a binding. The single connection interface may only facilitate connection with compatible bindings. Conventional boot systems may also include a system for modularity that enables interchangeable blocks to be positioned on the bottom of the boot. However, these conventional modular systems affect the performance of the boot binding system by effecting the sagittal height and/or angle between the boot and the binding. Embodiments of the present invention overcome these limitations by providing a modular system that enables boot binding compatibility between a wide range of connection schemes by enabling a custom binding interface surface position. In addition, the system ensures that the spacing and orientation of the boot with respect to the binding will remain consistent by maintaining a constant sole surface position.
- These and other features and advantages of the present invention will be set forth or will become more fully apparent in the description that follows and in the appended claims. The features and advantages may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. Furthermore, the features and advantages of the invention may be learned by the practice of the invention or will be obvious from the description, as set forth hereinafter.

- The present invention generally relates to a modular boot binding interface system. One embodiment of the present invention relates to a ski boot system with a modular binding interface. The system includes a shell encasing a user's foot and lower leg. A first and second block are interchangeably coupled to the shell below the base to effectuate alternative binding interfaces. The first and second blocks include a binding interface surface and a sole surface. The positioning and shape of the blocks with respect to the shell results in the binding interface surface extending distally from the toe region of the shell and the sole surface being the lowest surface on the boot system. The binding interface surfaces for each block are positioned at different sagittal heights with respect to the shell to facilitate the interconnection with alternative binding coupling systems. The sole surfaces for each block are positioned at substantially identical sagittal heights with respect to the shell to maintain optimum and consistent performance characteristics among different bindings. A second embodiment of the present invention relates to a ski boot system including a shell, a block, and a modular coupling system. A third embodiment of the present invention relates to a method for modularly coupling alternative blocks to a shell on a ski boot so as to effectuate alternative binding interface surface sagittal positions without substantially effecting sagittal sole surface orientation. Also, while embodiments of the present invention are directed at alpine touring and telemark ski boots, it should be known that the teachings of the present invention are applicable to other fields including but not limited to other types of boots.
- The following terms are defined as follows:
- Ski - Any type of skiing apparatus that allows a user to translate on a snow surface, including but not limited to cross country skis, alpine skis, powder skis, telemark skis, downhill skis, snowboards, splitboards, skiboards, etc.
- Sole - Any component(s) attached to the bottom of the shell of a boot including but not limited to a toe block, heel block, single sole piece, rigid members, attachment members, grip members, rubber pieces, etc.
- Toe block - One or more pieces of material attached on the bottom surface of a boot corresponding with the plantar surface of a user's foot, wherein the one or more pieces are disposed in a frontal region of the sole corresponding to the metatarsal and phalange bones of a user's foot.
- Heel block - One or more pieces of material attached on the bottom surface of a boot corresponding with the plantar surface of a user's foot, wherein the one or more pieces are disposed in a rear region of the sole corresponding in whole or part to the heel region of a user's foot.
- Binding interface surface - a boot system surface extending distally or proximally from the boot shell and upon which a binding may couple. For example a duckbill includes a binding interface surface extending distally from the toe region of the ski boot to enable the releasable coupling of a Telemark type binding.
- Sole surface - a boot system surface oriented as the lowest sagittal surface. For example, the surface of the boot system which is in direct contact with a binding. The sole surface may be composed of materials including but not limited to rubber and may include a tread pattern.
- Sagittal plane - An anatomical plane oriented vertically so as to bisect the left and right portions of the body. The sagittal plane is used herein for orientation purposes with respect to a boot as it is related to a human foot and lower leg. A boot which is placed on a human foot is effectively oriented sagittally (parallel to the sagittal plane) in a profile perspective. Therefore, the bottom of the boot is sagittally below the top of the boot. The term "sagittally" may also refer to a position within the sagittal plane such as an elevation.
- Transverse plane - An anatomical plane oriented horizontally so as to bisect the top and bottom portions of the body. The transverse plane is used herein for orientation purposes with respect to a boot as it is related to a human foot and lower leg. A boot which is placed on a human foot is oriented orthogonally to the transverse plane. Therefore, a transversely oriented member on the boot would extended horizontally or between the sides of the boot. For example, the bottom surface of the boot may three dimensionally extend transversely.

Figure 1 , which illustrates an inverted exploded perspective view of a boot system, designated generally at 100. The illustratedsystem 100 enables alternative blocks to be coupled to the shell to facilitate increased compatibility with binding systems. The system includes ashell 110 and twoboot bocks couplers 140 extending throughrecesses blocks shell 110 respectively. Thecouplers 140 may be any type of elongated coupling devices such as bolts, screws, pins, etc. Likewise, therecesses - Reference is next made to
Figures 2A and 2B , which illustrate profile views of a boot system with alternative blocks respectively, designated generally at 200 and 250 respectively.Figures 2A and 2B illustrate alternative boot blocks and the critical effect of the modular coupling system, which ensures that boot-binding performance is maintained across the alternative blocks.Figure 2A illustrates aboot system 200 comprising ashell 210, afront block 230, and arear block 235. The front andrear blocks shell 210 via a modular coupling system (not shown). Thefront block 230 further includes a bindinginterface surface 215, asole surface 245, and abinding interconnect 205. The bindinginterface surface 215 extends distally from theshell 210 and provides a surface upon which a portion of a binding system may couple (not shown). Thesole surface 245 is disposed sagittally below theshell 210 and forms the lowest sagittal surface of theboot system 200. The spacing between the bottom of theshell 210 and the bindinginterface surface 215 may be referred to as the shell-bindinginterface surface distance 220. The spacing between the bottom of theshell 210 and thesole surface 245 may be referred to as the shell-sole surface distance 225. The bindinginterconnect 205 provides a transverse connection point at which a binding may couple with theboot system 200. The bindinginterconnect 205 may provide a coupling for an alpine touring binding system (i.e. Dynafit-type binding). Therear block 235 includes a secondarybinding interface surface 240 which may be used in conjunction with the bindinginterface surface 215 and/or thebinding interconnect 205 to couple a binding to theboot system 200. Various additional binding interconnects (not shown) may be disposed on therear block 235 to facilitate interconnection with particular binding systems. -
Figure 2B illustrates acorresponding boot system 250, including thesame shell 260 asFigure 2A , afront block 280, and arear block 285. The front andrear blocks shell 210 via a modular coupling system (not shown). Thefront block 280 further includes a bindinginterface surface 265 and asole surface 290. The bindinginterface surface 265 extends distally from theshell 260. Thesole surface 290 is disposed sagittally below theshell 260 and forms the lowest sagittal surface of theboot system 250. The spacing between the bottom of theshell 260 and the bindinginterface surface 265 may be referred to as the shell-bindinginterface surface distance 270. The spacing between the bottom of theshell 260 and thesole surface 290 may be referred to as the shell-sole surface distance 275. Therear block 285 includes a secondarybinding interface surface 295 which may be used in conjunction with the bindinginterface surface 265 to couple a binding to theboot system 200. It is important to note that the shell-bindinginterface surface distance 270 illustrated inFigure 2B is different than the shell-bindinginterface surface distance 220 illustrated inFigure 2A . The different front blocks 230, 280 adjust the binding interface surfaces 215, 265 so as to be at a height that accommodates a particular binding. Conventional modular boot bocks maintain the same positioning of the binding interface surface with respect to the shell, but the sole surface adjusts to accommodate alternative binding connection schemes. Since the illustrated front blocks 230, 280 adjust the height of the binding interface surfaces 215, 265, the shell-sole surface spacing 225, 275 is substantially the same. Therefore, the spacing between the lowest surface of theboot system - Reference is next made to
Figures 3A and 3B , which illustrates a boot system with an alternative modular coupling system, designated generally at 300. The illustrated boot system 300 includes ashell 210 and afront block 330. Thefront block 330 is releasably coupled to theshell 310 utilizing the modular coupling system illustrated inFigure 3B . A cross-sectional orientation line A-A' illustrates the nature of the cross-sectional view shown inFigure 3B . The modular coupling system includes twoextended members 312 extending sagittally downward from theshell 310. The extended members include a transverse recess through whichh thecoupling member 314 is routed. Thecoupling member 314 is also routed through a transverse recess in thefront block 330. Therefore, the transverse routing of thecoupling member 314 through theextended members 312 and thefront block 330 effectively couples thefront block 330 to the shell. It will be appreciated that this particular modular coupling system may be used in conjunction with the other modular coupling systems illustrated throughout this application in accordance with alternative embodiments of the present invention. - Reference is next made to
Figures 4A-4G , which illustrate views of alternative modular coupling systems. The illustrated systems show the primary supportive structures of the boot blocks, but it will be appreciated that additional components may be added including but not limited to rubber outer surfaces.Figure 4A illustrates ashell 410 with abracket member receptacle 412 and abracket member 430. Thebracket member receptacle 412 includes a plurality ofrecesses 414 and a male geometrically keyedregion 416. Thebracket member 430 further includes a plurality of bracket recesses 430, a female geometrically keyed region 434 (only outside portion visible), and abinding interconnect 436. The female geometrically keyedregion 434 is shaped and configured to key with the malegeometrically region 416, thereby coupling thebracket member 430 to thebracket member receptacle 412 of theshell 410. In addition, various coupling members (not shown) may be sagittally routed through therecesses 414 and the bracket recesses 430 to further interconnect thebracket member 430 with theshell 410. The bindinginterconnect 436 includes transverse recesses for coupling with a binding system. Various rigid components may be disposed within thebracket member 430 to effectively support thebinding interconnect 436 with respect to theshell 410. The illustrated concept may be used to securely attach a block to a boot shell in a manner that provides the necessary stability for efficient binding attachment. For example, a Dynafit Tourlite binding system requires that a boot include two recesses on either transverse side of the toe portion of a boot. These recesses must be secured to the boot in a manner that minimizes the boots' ability to laterally pivot about these points. The illustrated concepts include multi-directional coupling between the block and the boot. The illustrated blocks are generally coupled to the boot via one or more attachment members which extend sagitally up from the bottom of the boot. In addition, a portion of the blocks key onto or over the boot in a manner that provides an additional three dimensional transverse direction of coupling between the block and the boot. Various other multi-directional blocks and attachment systems may be used in accordance with the present invention. -
