Definitions

  • ABSTRACT A ski boot for association with a ski, providing enhanced ski control, safety and comfort, comprising a lever element extending upwardly from a foot holder to the upperportion of the skiers lower leg and operatively associated with said leg to restrict both lateral and longitudinal motion of said lever with respect to said lower leg, whereby motion of said lower leg during skiing is virtually completely transferred to the ski without immobilizing the ankle joint.
  • SHEET DSUF 10 BACKGROUND OF THE INVENTION This invention teaches concepts for the design of ski boots of unprecedented performance, safety and comfort. In contrast to the history of the prior art, in which presentday boot designs for alpine skiing evolved from a succession of modest changes grandually generated over a period of years, this invention introduces a radical departure from current ski boot technology.
  • boots of early design which were comparatively low and flexible. These could be made to offer relatively good comfort and they allowed substantial mobility of the ankle joint a condition that is highly desirable for leg safety. Their flexibility, however, was a disadvantage from the standpoint of ski control.
  • the second class includes most of the ski boots currently available. They are very stiff and are often called rigid.” They employ stiff ankle cuffs that are relatively high, sometimes extending nearly half way up the lower leg. These boots virtually immobilize the twisting motion and the lateral flexure normally available in the ankle joint. Most boots in this class severely limit forward and rearward flexure of the ankle joint, too, while some utilize pivoted ankle cuffs that offer less restraint to forward flexure.
  • the primary benefit of the rigid boot is improved skiing performance. Since lateral flexure of the boot is minimized, the lateral angle of the ski follows the angulation of the lower leg with good fidelity. This leads to controlled edging of the skis, which is vitally important for skier control. In addition, the boots resistance to forward and rearward flexure helps the skier transfer weight to the front or rear of his skis to perform maneuvers that would be much more difficult with flexible ski boots.
  • the now common boot-top fractures are spiral or flexural fractions of the tibia and fibula, the main bones of the lower leg. They are usually multiple fractures, involving both bones, with one or more breaks in each, and located in the general vicinity of the top of the ankle cuff. Treatment usually requires immobilization for three months by a heavy plaster cast extending from the foot to the thigh, followed by a long period of restricted use and muscle regeneration.
  • the common type of injuries previously encountered with flexible ski boots were ankle sprains and simple fractures. The latter usually involved a four to six week recovery period, with much less patient discomfort and much more patient mobility.
  • the present invention provides virtually complete transfer of motion of the lower leg to the ski, without immobilizing the ankle joint.
  • the result is unprecedented ski control with greatly enhanced skier comfort and safety. This may be accomplished by using a low shoe in conjunction with a lever, yoke and strap, that connects the shoe to the upper portion of the leg.
  • the ankle cuff of prior art ski boots is eliminated, and with it immobilization of the ankle joint is eliminated.

  • FIG. 16 illustrates a configuration of an eccentric pivot device that can be used in conjunction with pivoted levers to provide for adjustable lateral cant of the foot
  • FIG. 17 is a view taken along line l717 in FIG. 16.
  • FIG. 1 Basic elements of the invention are illustrated in FIG. 1. They are a shoe 11 which encloses the foot, a lever 12 attached to the shoe and extending to the upper portion 18 of lower leg 15, a yoke 13 attached to the lever and designed to restrain lateral motion of the leg with respect to the lever, and a strap 14 that restrains longitudinal motion of the leg with respect to the lever.
  • Projections l6 and 17, or other means provided for firm attachment of the boot to the ski may be integral parts of the shoe as illustrated. They may alternatively be integral parts of the lever, or both.
  • Projections 16 and 17 are engaged by safety release binding elements 19 and 20, respectively, the bindings being permanently afixed to ski 61, front and rear ends ofwhich are broken away.
  • the lever is a stiff element and may be made from metal, fiberglass or other stiff material.
  • the yoke too, is relatively stiff, while the strap and upper portion of the shoe may be flexible, made for example from woven fabric or leather.
  • the shoe may be of the low quarter type or extend above the ankle.
  • the sole of the shoe may be either stiff or flexible, depending upon v the type of bindings used to attach the boot to the ski.
  • Part 21 is a strap designed to retain the heel of the foot firmly in the corresponding portion of the shoe; 22 is a pad designed to distribute the pressure of strap 21 over a sufficiently large area of the foot for comfort. Strap 21 may be located inside the shoe as shown, or it may be outside the shoe, or it may be partly inside and partly outside; it may tie or buckle or otherwise fasten either inside or outside the shoe.
  • Jacket 23 is a waterproofing and insulating covering for the leg; it may be made of a highly flexible material and would usually be designed such that it is attached to shoe 11 at the bottom and to yoke 13 or strap 14 at the top.
  • the jacket may be designed with a closure, such as a zipper or other means, or it may be sufficiently wide to allow direct entry of the foot.
  • strap 14 would usually be designed with an adjustable closure, such as a buckle.
  • the lever design shown in FIG. 3 consists of three parts, wherein 31 is an exchangeable leaf-spring member fitted firmly to parts 32 and 33 by means of sockets 34 at its ends.
  • Spring 31 may be selected by the skier from several interchangeable springs of different longitudinal and lateral flexibilities.
  • the lever mechanism of FIG. 4 comprises part 41 firmly attached to the shoe and lever 12 connected thereto through hinge 42 and captive adjusting screw 43. With this device the skier may adjust his forward lean position, that is, he may adjust the angular position of his leg with respect to the ski.
  • Projection 16 is shown here as an integral part of member 41 and provides means for engagement of a ski binding part to the ski boot.
  • FIG. 5 wherein the mechanism comprising cable 51, spring 52, screw 53 and nut 54 provides adjustable resilience for lever 12.
  • the skier increases his forward lean by pressing with his leg against strap 14 and simultaneously increases the load on the front of the ski. Increased resilience is achieved by tightening nut 54, thus increasing the preload on the spring.
  • Spring 52 may be a metal compression spring of conventional design, it may be an elastomeric block such as rubber, or it may be some other elastic member.
  • a skier may also choose to adjust nut 54 such that there is no spring preload, or by backing off further to provide a zone of free-hinging action before the spring affects the lever.
  • Another device consisting of a screw 55 pivoted at 56 and two nuts 57, acts as an adjustable forward and rearward stop. These control the maximum and minimum forward lean during skiing. For comfortable walking, the device may be disengaged by pivoting it to position 58, where it is held in place by toggle spring 59.
  • FIG. 6 illustrates schematically a ski 61 with a lever 12 firmly attached to it.
  • force F When the skier presses his leg forward against strap 14 (see FIG. 1), force F, is transmitted to the lever.
  • An equal reactive force F is applied by the foot to the back of the shoe and in turn the force is transferred to the lever.
  • P P The weight of the skier and any other vertical force is exerted by the foot on the shoe and transmitted to the ski as P P is the resultant force (neglecting friction) of the pressure of the snow against the ski.
  • the figure shows that the lever is aptly named, since the effect of the snow on the ski depends upon force F times lever arm h.
  • the forces acting on a conventional ski boot under the same circumstances would extend continuously along the front of the ankle cuff and top of the shoe and could not be represented by a force times a well-defined lever arm.
  • FIG. 7 introduces designs in which the lever is hinged about an axis near the ankle joint. This hinge location minimizes vertical motion between strap 14 and the leg, increasing comfort.
  • Refinements include heel retention strap 21; waterproofing and insulating jacket 23; pivot 71 for articulation of the lever with respect to the shoe; mechanism 72 to provide for adjustable longitudinal resilience of the lever by the action of a spring connected to the shoe through cable 73; adjustable angle of minimum forward lean by means of member 74, the
  • padded yoke 13 resists the rearwards force of the leg and distributes the pressure over a sufficiently large area for comfort; the lever itself does not engage the leg.
  • FIG. 7 The boot design of FIG. 7 is shown in its maximum forward lean position in FIG. 8.
  • cable 76 is straightened and extended to its maximum length, so as to act as a stop on the pivoting of the lever with respect to the shoe.
  • the forward lean force, applied by the leg to strap 14 increases with forward lean angle until the maximum lean is attained. Then, still larger forward lean forces may be applied to the strap, but without further increase of lean angle.
  • the maximum forward lean angle may be adjusted to suit individual skiing styles. However, the lean angle cannot be made so large as to exceed the natural mobility of the ankle, thus protecting the ankle joint and Achilles tendon from damage.
  • FIG. 9 shows the same boot in its free-hinged mode
  • stop 74 is moved into its non-working position.
  • Projection 78 is provided so that stop 74 may be lifted to this position with the ski pole. The comfort of walking is greatly enhanced in the free-hinged mode, since the angular motion of the lever relative to the shoe is unrestricted over the range of angles employed in most natural walking situations.
  • FIG. 10 A cross-sectional view of one design for mechanism 72 and stop 74 is shown in FIG. 10.
  • the force exerted by spring 101 is transmitted to cable 73 through slider 102.
  • the effective length of the cable is adjusted by means of screw 103 and locked by 104, thereby providing means to adjust the preload on the spring.
  • Hinge 105 provides means to disengage stop 74 into its non-working position.
  • FIG. 11 illustrates a ski boot of another physical configuration but it is equivalent to the configuration of FIG. 2.
  • the shoe 11, the lever 12 and the yoke 13 may be separate parts that are fastened together firmly, or they may be constructed as one continuous piece. In the latter case, a relatively stiff material such as a metal, a composite such as fiberglass, or a hard plastic would be suitable.
  • Strap 14, which engages the upper part of the calf of the leg can be designed with an adjustable buckle 111 or equivalent closure. The leg presses against the lever through pad 1 13, but does not engage the lever below the pad.
  • Jacket 23 would again be made of waterproofing and insulating material, and it can have a closure at the rear, such as a slide fastener (zipper). Heel retention strap 21 would be most satisfactory when designed with an external adjustable lock, such as illustrated by 112.
  • Lever I2 is connected to shoe 11 through pivot 71, which is located near the ankle joint of the foot.
  • Mechanism 122 is firmly attached to the shoe at the front end and attached to the lever at the other end through a quickrelease ball and socket device. This mechanism provides adjustable longitudinal resilience of the lever and adjustable stops for maximum and minimum forward lean angles; disengagement allows free-hinging action.
  • Cylinder 131 is attached firmly to the shoe.
  • Connecting rod 132 travels freely within the cylinder, with longitudinal limits set by adjustable stop 133 for forward motion and fixed pin 134 engaging the right end of slot 135 for rearward motion.
  • Elastomeric O-ring 136 functions as a guide for lateral position of the connecting rod.
  • Spring 1137 is compressed between cylinder 131 and adjusting nut 138 to provide adjustable resilience; tightening the nut increases the preload and resilience.
  • Locknut 139 functions to maintain the adjustment.
  • Extension 140 is threated into connecting rod 132 and is provided with a ball on the other end to engage the lever; 140a acts as a locknut. For use, the minimum forward lean angle is adjusted by screwing extension 140 in or out of the connecting rod; maximum forward lean angle is adjusted next by turning stop 133; and spring preload is adjusted by means of nut 139.
  • FIG. 14 illustrates another variation of the pivoted lever design.
  • lever 12 is in front of the leg, and articulated with respect to shoe 1 1 at pivot 71.
  • a mechanism is housed within the rear portion of the shoe, comprising a reel and torsional spring.
  • Cable 141 is attached to the lever member as indicated and to the reel.
  • the torsional spring engages the reel so as to apply torque to the reel and tension to the cable.
  • Adjusting screw 142 engages the reel and acts as an adjustable stop to limit the maximum forward lean angle of the lever.
  • Adjusting screw 143 engages the spring and varies the initial torque, which in turn varies the preload on cable 141.
  • Bar 144 acts as a stop by engaging adjusting screw 145, so as to limit the minimum forward lean of the lever.
  • bar 144 may pivot about fastener 146 into a non-working position to allow free-hinging of the lever for comfortable walking.
  • FIG. 15 illustrates yet another variation of the pivoted lever in front of the leg.
  • Curved leaf-spring or torsion spring 151 is firmly fixed to shoe 11 at its lower end 152.
  • Adjustable cam 153 is fastened to lever 12 and it abuts and presses against spring 151 to provide longitudinal resilience of the lever. Spring preload is adjusted by rotating and then locking cam 153.
  • Adjustable stop 154 engages fixed pin 155 to limit the maximum forward lean and engages retractable pin 156 to limit minimum forward lean. Free-hinging action for comfortable walking is obtained by retracting pin 156 into shoe 11; retraction may be actuated automatically by removing the ski boot from the ski, or it may be actuated manually by moving a handle on the boot.
  • FIGS. 16 and 17 illustrate one type of device that can be used in conjunction with pivoted levers to provide an additional special feature, namely lateral cant of the foot.
  • 161 represents the wall of the shoe and 162 the wall of the lever.
  • the eccentric cam device is made in three parts, the eccentric cam 163, the handle 164 which engages the cam by a spline shaft or other non-rotating shaft, and washer 165. Whereas a pivot would normally be arranged to maintain the axis of the hinge parallel to the sole of the shoe, this device allows adjustable deviation from that parallelism to compensate for bow and other deformities of a skiers legs. In operation, handle 164 would be rotated until the correct lateral cant is achieved and then moved to the nearest detent groove 166 preformed in lever 162.
  • pad 22 used in conjunction with heel retention strap 21, may be in the form of a flexible pneumatic bag; or it may be a liquid filled bag; or it may be filled with non-packing solid particles.
  • Pad 22 may also be a semi-rigid material contoured to bear primarily on each side of the front of the ankle, thus avoiding a concentration of pressure on the tendon.
  • the lever may be connected to an auxiliary device which may be a frame, platform or other external structure into which a shoe may be inserted and clamped or otherwise fastened. Then the skier may wear comfortable shoes or flexible hiking boots, and still achieve excellent ski control from the action of the lever and attached parts.
  • said auxiliary device may contain safety release mechanisms, called safety release bindings, for attachment to the ski. Said device that accepts the shoe may itself be enclosed with waterproofing and insulating material.
  • safety release bindings may also be incorporated as integral parts of the boot, for example in the sole of the shoe.
  • PERFORMANCE ENHANCEMENT In modern skiing techniques, the vitally important aspects of ski control are edging, or the ability to control the lateral angle of the ski with respect to the snow surface; weighting of the ski tips, or the ability to control the location of the center of pressure between the front of the ski and the snow; and sit-back stability, or the ability to maintain a stable position of the lower leg relative to the ski while the center of gravity of body weight is behind the foot.
  • ski boots available today are designed to be very snug fitting and very stiff, so as to transfer motion of the lower leg to the ski with good fidelity. Ski boots made according to the present invention accomplish this transfer of motion still more effectively and efficiently.
  • lever-yoke-strap system The effectiveness is inherent in the lever-yoke-strap system.
  • the lever, yoke and strap are indirectly but firmly attached to the ski. Since the lever and yoke are stiff members, lateral angular motion of the lower leg is completely transferred to the ski. The result is an unprecedented positive control of edging.
  • FIG. 6 illustrates the forces applied by the skiers body to the lever-ski system.
  • F and therefore F to increase by his forward lean, that is by pressing against strap 14
  • P moves forward, increasing distance d, and thus maintaining the moment of P, and P, equal to the moment of F, and F
  • a skiers adjustment of forward lean controls the location of the force of the snow against the front of the ski or in popular skiers language, it controls the load or weight on the front of the skis. This effect is uniquely consistent, since the distance between F, and F, does not vary.
  • the lever provides unprecedented support to the lower leg for sit-back maneuvers.
  • the lever establishes and firmly holds the leg in the minimum lean position, without regard to the rearward displacement of center of gravity.
  • the ski boots of this invention achieve control objectives with much greater efficiency than conventional boots, inasmuch as the forces that must be applied near the top of the lever are much smaller. Indirect advantages for control are substantial. For example, with conventional boots forward lean is often limited by the pain of localized boot forces; the greater lean consistent with improvedskiing or with the demands of an instructor is not attempted.
  • hinged boots of this invention Another important performance attribute of hinged boots of this invention is a shock absorption feature.
  • a skier should try to maintain his center of gravity in a smooth line of motion, while his skies and feet travel the undulating path.
  • the legs flex and accommodate the bumps.
  • the upper leg is used alone to produce the desired up and down motion of the body; then, a subsidiary and undesirable backwards and forwards displacement of the center of gravity is produced.
  • the positive stop that limits forward lean prevents excessive longitudinal flexure of the ankle and eliminates the serious problem of damage to the Achilles tendon.
  • the ski boot of this invention is effective for all ability levels.
  • the beginner would especially profit from the easy edging control and the enforced lean.
  • the object of the familiar plaintive cry of the ski instructor, bend the knees" is automatically achieved!
  • the advanced skier would take advantage of the ease and certainty in loading the ski tips and the'great support for sit-back maneuvers. All skiers would gain from their relative safety and comfort.
  • the adjustable qualities of the ski boot allows for a broad range of skiing styles and conditions. For example, steep terrain would normally call for an increased minimum forward lean; heavily moguled terrain would call for increased spring preload for greater lever resilience. Certain racing techniques would call for a locked lever. These variations and many others can be accommodated.
  • FIGS. 14 and 15 Preferred implementations are illustrated by FIGS. 14 and 15. They incorporate the basic components of shoe, lever, yoke and strap, together with numerous re finements described previously. In addition, they have the advantages of extremely easy foot entry, shin protection, effective snow shielding and attractive design. It is to be understood that while the above has been indicated as preferred implementations, numerous variations or modifications therein may occur to those having skill in this art and what is intended to be covered herein is not only the illustrated forms of the invention, but also any and all modified forms thereof as may come within the spirit of said invention.
