Definitions

  • This invention relates to ski boots and more particularly to improvements in rear entry ski boots.
  • Rear entry boots may comprise a rigid, outer shell, a heel (or rear) spoiler which is hingedly connected to the outer shell, and calf and shin cuffs which engage the lower portion of the wearer's leg.
  • These boots also feature inner boots or boot liners, often made from flexible foam materials and fabrics, within which the wearer's foot is held.
  • One or more buckles may hold the spoiler and calf cuff to an upper portion of the shell to close the boot.
  • Such boots may be opened, to insert or remove the foot, by releasing the buckles and allowing the top of the spoiler to pivot rearwardly.
  • the shell of such boots may be referred to as having a "fixed volume" because the shell is rigid and does not compress to engage the foot.
  • Foot restraint systems have been developed to hold the skier's foot within the boot to assist in providing ski control.
  • Such foot restraint systems typically comprise cables or straps which are mounted interior of the outer shell and are positioned so as to act upon the boot liner to hold the foot in position. These straps are usually actuated by a buckle located on the outside of the boot. Although these foot restraint systems provide some ski control, aggressive skiing may loosen the foot restraint systems, or cause the foot to become momentarily displaced.
  • ski boot which bridges the gap between typical rear entry ski boots and front entry ski boots by providing skier comfort as well as acceptable ski control. Accordingly,. it is an object of the invention to provide a ski boot which features easy and convenient foot entry and exit. Another object of the invention is to provide a ski boot which features enhanced ski control without sacrificing comfort. A further object of the invention is to provide a rear entry ski boot having the features noted above. It is also an object of the invention to provide an easily actuated tightening mechanism for the inner shell of the boot. Other objects of the invention will be apparent to those of ordinary skill in the art upon reading this disclosure.
  • the present invention comprises a ski boot having a substantially rigid outer shell; an inner, selectively variable volume shell; a heel spoiler which is hingedly connected to the outer shell; and an inner boot liner which engages the wearer's foot and is disposed between the foot and the inner shell.
  • the boot may also feature a calf cuff mounted above the heel spoiler and/or a shin cuff hingedly affixed to a front portion of the outer shell.
  • the inner shell is somewhat flexible and is disposed interior of the rigid outer shell.
  • the inner shell has a sole portion with raised side walls and heel, arch, metatarsal and phalanx regions.
  • the inner shell functions to assist in providing foot support and ski control as its phalanx region is affixed to the sole of the outer shell. Additional support is provided, when the boot is closed, due to a hinged connection between the heel region of the inner sole and the heel spoiler.
  • the inner shell also features a saddle region which extends over portions of the instep region of the foot.
  • the saddle region of the inner shell is somewhat flexible and tensioning elements, such as cables, may engage the saddle region to selectively tighten the inner shell in the saddle region.
  • the tensioning elements may be linked to the heel spoiler so as to be tightened and loosened upon the closing and opening of the heel spoiler.
  • the saddle does not cover the entire top portion of a wearer's foot. Rather, voids are present in the shell over areas of the foot which are known to be particularly sensitive to pressure.
  • the inner shell also features an ankle support structure for engaging the ankle region or lower shin area of the wearer.
  • the ankle support structure comprises a bracelet or band which engages a portion of the wearer's leg just above the malleolus.
  • the ankle bracelet may be secured to the remainder of the inner shell by vertical extensions which are directed upwardly from either side of the heel region of the sole to integrally connect to the bracelet.
  • the ankle support functions to maintain contact between the wearer's foot and the sole of the boot for added ski control.
  • the ankle support structure may be constructed such that the vertical extensions originate from the heel region of the sole, and pass behind and around the malleolus to the bracelet which is disposed over a portion of the lower shin.
  • the vertical extensions may originate from the heel region of the sole, and pass around the front of the malleolus to the bracelet.
  • the ankle support structure of the inner shell cooperates with either the heel spoiler, which is hingedly connected to both the outer shell, and the inner shell, or with the shin cuff to provide support to the ankle region and lower shin region of the skier by helping to maintain the skier's foot in the proper position within the boot.
  • the invention features a hinged inner sole which may or may not be used in conjunction with the flexible inner shell.
  • the hinged sole is secured to the outer shell of the boot in the phalanx region of the sole.
  • a sole hinge or creased sole portion is disposed approximately at the border of the metatarsal and phalanx regions of the sole to enable the heel, arch and metatarsal regions of the sole to pivot relative the phalanx region.
  • the heel spoiler is pivotally attached to both the heel region of the sole and the outer shell of the boot to facilitate pivotal movement of the heel, arch and metatarsal portions about the sole hinge.
  • the hinge connecting the heel spoiler to the inner sole is disposed at a forward portion of the heel region, slightly below an imaginary line connecting the spoiler-outer shell hinge and the metatarsal hinge.
  • opening the heel spoiler by moving it rearwardly causes it to pivot about the spoiler-outer shell hinge.
  • this hinge it simultaneously pivots about the spoiler-inner sole hinge and also elevates the heel, arch, and metatarsal regions of the sole, causing these regions to pivot about the sole hinge.
  • the sole of the inner shell may also feature a width-adjustable metatarsal region.
  • a centrally located gap is disposed in the phalanx, metatarsal and arch regions of the sole. This gap extends parallel to the central axis of the sole.
  • a fastening element such as a threaded screw may be tightened to decrease the width of the sole, and loosened to increase the width of the sole.
  • the inner shell of the present invention is disposed interior of and adjacent to the outer shell. While the outer shell is of a fixed volume, the inner shell may be described as having a selectively variable volume. That is, tensile elements, such as cables, act upon the saddle region of the inner shell and the ankle support of the inner shell to anchor the foot in a desired position during skiing activities.
  • the relative flexibility of the inner shell enables the volume within the shell to decrease upon actuation of the tensile elements and foot restraining devices and to firmly retain the foot in position.
  • the relatively large surface area of the saddle region and the ankle support structure provides added foot support without detracting from wearer comfort.

  • Figure 14 is a side view, partially cutaway, of the ski boot of Figure 13, in the open position.
  • a ski boot 10 has, as shown in Fig. 1, an outer shell 12 having a sole portion 14; a shin cuff portion 16; a heel spoiler 18; and calf cuff 17.
  • sole portion 14 may be subdivided into heel 14a, arch 14b and metatarsal 14c regions.
  • the illustrated boot also comprises an inner shell 20 disposed interior of an adjacent outer shell 12.
  • a boot liner 22, designed to comfortably engage the skier's foot is removably and replaceably seated inside shell 20.
  • Boot liner 22 may be made of a flexible, padded foam material and the construction of this item is well known in the art.
  • a shin cuff closure mechanism 24 may be utilized to hold the calf cuff 17 and shin cuff 16 together to close the boot.
  • ankle bracelet tightening mechanism 26 may be rear mounted to partially close the boot by maintaining the heel spoiler 18 in a closed position relative to ankle support 62. Tightening mechanism 26 also assists in tightening the ankle support 62.
  • Tension control mechanisms 28, 30 may be disposed on the top instep portion 32 of boot 10 to vary the volume within the inner shell and to provide selective control of a foot restraining system disclosed below.
  • the outer shell 12 is constructed of materials and in a manner well known in the art.
  • the outer shell 12 may be subdivided into a heel region 33, a toe region 34, and an instep region 32.
  • the outer shell 12 is illustrated in Fig. 1 as having a continuously rigid surface over instep and toe regions 32, 34, it may also have a non-continuously rigid surface in which non-rigid areas 94 are disposed in and around the instep region 32 of the boot as shown in Figure 11.
  • the shin cuff 16 and calf cuff 17, as illustrated in Figure 1, are of the type conventionally used in ski boot constructions.
  • the shin cuff 16 may be hingedly connected to the outer shell 12 by pin 35.
  • shin and calf cuffs 16, 17 cooperate, when closed by closure mechanism 24, to support the lower leg just above the skier's ankle and to provide forward and rearward lean control. It is understood that either the shin cuff 16 or calf cuff 17 may be omitted from a ski boot constructed according to the present invention, without a loss of ski control or foot support.
  • inner shell 20 is disposed interior of and adjacent to outer shell 12.
  • Inner shell 20 comprises a sole portion 36 having heel 36a, arch 36b, metatarsal 36c and phalanx 36d regions.
  • the sole portion 36 of inner shell 20 also has elevated side walls 38 which surround the sides of a skier's foot.
  • Saddle region 41 is more flexible than the side walls 38 and sole portion 36 of the inner shell. In this way the saddle 41 may be compressed about the wearer's foot to provide a selectively variable volume within the inner shell.
  • Saddle 41 may overlap side walls 38 to a slight degree (e.g., 0.5 - 1.5 cm) in order to facilitate compression of the saddle portion of the inner shell.
  • One or more tensile elements may extend around the inner shell and engage the saddle, cooperating with a tension control mechanism or other means to selectively vary the volume in this region of the inner shell.
  • saddle 41 comprises saddle components 40 and 42.
  • Component 40 is, on one side of the inner shell, integral with side wall 38, and extends over the instep region of the wearer's foot.
  • Component 40 overlaps with side wall extension 39a by approximately 0.5 to 1.5 cm.
  • Saddle component 42 is similar in construction to component 40, but is disposed approximately over the metatarsal region of a wearer's foot.
  • the inner sole has been described as having a saddle component which may be in one or two pieces. Also, it is understood that one skilled in the art may easily devise alternative embodiments of the saddle feature of the present invention, while remaining within the scope of the present invention. Such alternative embodiments will provide a means of applying support to the wearer's foot by acting on instep and metatarsal regions of the foot, while avoiding the application of force to known pressure sensitive areas of the foot. For example, one may utilize a strap extending over the instep portion of the wearer's foot and an additional strap extending over the metatarsal portion of the foot.
  • Tensile elements 44, 46 act in conjunction with saddle components 40, 42 to secure the skier's foot within the boot in order to provide ski control.
  • Tensile element 44 comprises a cable, strap, like structure or combination thereof which extends over and in contact with saddle component 40.
  • Tensile element 44 extends under a bottom portion of sole 36 and may extend through cable guide 50 which is anchored to the sole 14 of outer shell 12.
  • One end 52 of tensile element 44 may extend to the exterior of outer shell 12 and may be secured within a tension control mechanism 30 disposed on the outer shell 12 in an area adjacent the instep of a wearer's foot. The opposite end of tensile element 44 may be secured to tension control mechanism 30 or to side wall extension 39a.
  • tensioning element 46 comprises a cable, strap, like structure or combination thereof which passes beneath inner shell sole 36.
  • Tensile element 46 need not be anchored to outer shell sole 14.
  • One end 58 of tensile element 46 is secured to a tension control mechanism 28 which is secured to the metatarsal region of outer shell 12.
  • the opposite end of tensile element 46 may be secured to tension control mechanism 28 or to side wall extension 39b.
  • tensile elements 44, 46 may secure the skier's foot within the boot without the need for a buckle mechanism. Instead of a buckle-type closure mechanism, tensile elements 44, 46 may be actuated by simply opening and closing the heel spoiler. Tensile elements 44, 46 extend from the saddle components 40, 42 and pass under, and/or around, the sole 36 of the inner shell 20. Tensile elements 44, 46 extend from beneath sole 36, around the heel portion 36a, to terminate in a tension adjusting mechanism 110 mounted on a rear portion of the heel spoiler 18. Preferably, tensile element 46 extends from saddle component 42 around the side of the boot and through channel 112 which directs cable 46 under, and/or around, sole 36.
  • channel 112 is curved within sole 36 so as to direct cable 46 around the heel portion of the sole 36a.
  • cable 46 extends upwardly around to the rear portion of the heel spoiler 18.
  • Cable 46 is threadedly secured to a tension adjusting mechanism 110a which is mounted to the rear of heel spoiler 18.
  • cable 44 extends from saddle component 40, around the side of the boot and through channel 114 and around heel portion 36a. Cable 44 then extends upwardly to the heel spoiler 18 and becomes threadedly secured to tension adjusting mechanism 110b.
  • Tension adjusting mechanism 110a, b are secured to the heel spoiler 18. Due to the threaded connection of tensile elements 44, 46 the overall length of those cables may be lengthened or shortened to control their tension. The tension may be adjusted so that when the boot is in the closed position (as shown in Figure 13), tensile elements 44, 46 compress the saddle 41 of inner shell 20 to an extent sufficient to provide the required foot support. Conversely, when heel spoiler 18 is in the open position (as shown in Figure 14), the tensile elements 44, 46 are slackened and tension is released to an extent sufficient to allow foot entry and exit.
  • a boot constructed according to this embodiment of the invention may be utilized as follows. With the boot in the open position, as shown in Figure 14, a skier may insert his foot within the boot. Upon closing heel spoiler 18, tension is applied to tensile elements 44, 46, causing them to compress the saddle 41 to impact support to the wearer's foot. Preferably, the length of the tensile elements 44, 46 above the sole of the boot is increased by approximately 1.0 to 1.5 cm upon loosening heel spoiler 18. When the boot is closed the length of the tensile elements above the sole is decreased by a similar amount. Tension adjusting mechanisms 110 allow for approximately 3.0 to 3.5 cm of adjustment to the length of tensile elements 44, 46 in order to accommodate wearers having various foot sizes and shapes.
  • inner shell 20 also comprises an ankle support structure 62 which may be integral with and extend upwardly from side walls 38.
  • the ankle support structure 62 originates on either side of the heel region 36a of sole 36.
  • Vertical members 62a extend upwardly from side walls 38 and may pass behind the malleolus of the wearer's foot. Alternatively, vertical members 62a may instead pass in front of the malleolus. The vertical members 62a then continue around the lower leg of the wearer to a bracelet or band portion 62b which supports the lower shin of the wearer.
  • Ankle support structure cooperates with heel spoiler 18 to assist in providing foot support and excellent ski control by ensuring that the wearer's heel remains in contact with the sole of the ski boot.
  • heel spoiler 18 is in the open position to allow foot entry to the boot.
  • an outer portion 19 of heel spoiler 18 may surround and frictionally engage vertical members 62a of the ankle support.
  • the heel spoiler 18 will remain secured in the closed position when buckle mechanism 26 is locked.
  • ankle support structure 62 and heel spoiler 18 cooperate to grasp the wearer's leg, slightly above the wearer's malleolus, to maintain the wearer's foot in contact with the boot. That is, the ankle support assists in providing foot support and ski control by maintaining the back of the wearer's leg in contact with the heel spoiler and ensuring that the wearer's heel is maintained in contact with the sole of the boot.

Abstract

Une chausssure de ski (10) comprend une enveloppe extérieure rigide et une enveloppe intérieure (20) relativement souple. Ladite enveloppe intérieure comporte une région relativement souple en forme de selle s'étendant sur les parties métatarsiennes et/ou du cou-de-pied du pied de l'utilisateur. Des éléments extensibles, tels que des cordons ou des sangles, coopèrent avec ladite selle pour ménager une force de support variable (10) au pied de l'utilisateur. Lesdits éléments extensibles (44, 46) s'étendent à partir de la selle (41), sous la semelle de l'enveloppe intérieure et aboutissent sur le déflecteur du talon. Cette conception permet d'appliquer une force de tension de support aux éléments extensibles par pivotement dudit déflecteur du talon (15) en position fermée. L'ouverture dudit déflecteur du talon a pour résultat de relâcher les éléments extensibles et de libérer la force de support du pied. L'enveloppe intérieure (20) de la chaussure comporte également une structure (62) de support (20) de cheville, venant au contact de la jambe de l'utilisateur à un point situé juste au-dessus de la malléole, et coopérant avec le déflecteur du talon afin de maintenir le talon de l'utilisateur en contact avec la semelle de ladite chaussure.
