Definitions

  • ski boots are relatively bulky and heavy.
  • Various provisions have been made to give ski boots some flexibility, where permissible or desirable, without forsaking their function of transmitting control of direction from the skier to the skis.
  • modern ski boots extend to varying degrees above the wearers ankle so as to embrace the lower portion of the lower leg.
  • the forward lean angle of a ski boot can be defined as the included angle between the axis of the lower leg embracing portion of the boot and a line normal to the plane of the ski, or the sole of the boot.
  • the forward lean angle is preferably larger for certain types of skiing, as for example, downhill racing where the skier is more crouched, and smaller for other types of skiing,
  • Prior art boots have been provided with a cuff which engages the skiers lower leg and which is pivotally connected to the foot-embracing portion of the boot whereby the angle of forward lean can be varied.
  • a stop member is mounted on the heel part of the boot to engage the cuff as it pivots backward thereby limiting the extent to which it can pivot backward so as to define a minimum forward lean angle for the boot.
  • the stop is generally adjustable so that the minimum forward lean angle can be varied.
  • Typical constructions of this type as shown in U.S. Pat. Nos. 3,543,421, issued Dec. 1, 1970 to G. B. Ader; and 3,775,871, issued Dec. 4, 1973 to R. A. Serko.
  • the ski boot of this invention is of the rear entry variety and includes a foot-embracing portion which receives the forward portion of the foot.
  • the forward part of the lower portion of the wearers lower leg is covered by a part of the boot which extends upwardly from the foot-embracing portion thereof and which is preferably immobile with respect to the foot-embracing portion of the boot.
  • the boot further includes a rear part which covers the wearers heel and the rearward part of the lower portion lower leg, and which is pivotally mounted on the foot embracing part of the boot.
  • the rearward and forward edges of the front and rear parts of the boot respectively are preferably overlapping and there are provided preferably strap means having associated buckles which strap means encircle the ankle and lower leg parts of the boot to secure the boot on the wearers foot.
  • the front and rear parts of the boot have upper edges and are at least partially nestable or overlapping so that their upper edges can be adjusted to fit snugly about the lower portion of the lower leg of the wearer.
  • a predetermined effective circumferential dimension for the upper edges of the front and rear parts of the boot is established and retained by the buckle and strap members being adjusted.
  • the particular size of the predetermined effective circumferential dimension will be determined in accordance with the size of the wearer's leg, the snugness of fit, and the like.
  • the front part of the boot is provided with an opening which extends through the upper edge thereof, which opening provides opposing edges and is preferably in the shape of an inverted key hole.
  • a number of different size wedges are provided which can be positioned in the opening so as to offset the opposing edges thereof a plurality of different distances from each other in such a manner as to effectively increase the length of the upper edge of the front part of the boot. Once this increase in edge length is accomplished, the boot is refitted on the foot of the wearer and the straps are adjusted to their predetermined dimension.
  • the upper edge of the front part of the boot has enlarged its dimension, it will contribute more to the total circumferential leg-encircling dimension than previously, and the rear part of the boot will be pulled by the straps into greater overlap or nesting with the front part of the boot. This will result in the rear part of the boot being pivoted forwardly more about its pivot thereby increasing the minimum forward lean angle of the boot.
  • FIG. 1 is a side elevational view of an embodiment of a ski boot formed in accordance with this invention
  • FIG. 2 is a front elevational view of the boot of FIG.
  • FIG. 3 is a fragmented front view of the upper part of the front of the boot of FIG. 1 with the covering cuff removed for clarity;
  • FIG. 4 is a perspective view of a wedge member designed for use in conjunction with the boot of FIG. 1 for varying the forward lean angle thereof;
  • FIG. 5 is a view of the boot similar to FIG. 3 but showing the wedge in place; 1
  • FIG. 6 is a somewhat schematic plan view of the uppermost part of the boot which encircles the lower leg of the wearer, the remainder of the boot not being shown for reasons of clarity;
  • FIG. 7 is a view similar to FIG. 6 but showing the ef fect of inserting the wedge in place in the boot.
  • FIG. 1 a ski boot of the rear entry variety.
  • the boot includes an outer shell 2 having a forward portion 4, a sole 6, and a rearward portion 8.
  • the rearward portion 8 is pivotally connected to the sole 6 and forward portion 4 by means of a pair of aligned pins (one of which is shown).
  • the boot is shown in FIG. 1 in its closed condition, e.g. as it is worn, and it will be understood that the rearward portion 8 is pivoted to the rear about the pins 10 and away from the forward portion 4 to permit insertion of the foot into the boot.
  • the forward and rearward portions 4 and 8 meet at 12 wherein an overlapping or nesting interface is formed as is most clearly shown in FIGS. 6 and 7.
  • the rearward portion 8 nests inside of the forward portion 4.
  • the boot also includes an inner liner member 14 formed from rubber or some other soft and resilient material.
  • the liner 14 actually receives the wearers foot and is formed like a slipper.
  • the liner 14 is also divided into forward and rearward parts 16 and 18 respectively which are separated by opposed vertical parting lines 20 (one of which is shown).
  • the parting lines 20 also take the form of overlapping or nesting joints, with the rearward part 18 preferably nesting inside of the forward part 16. It will be readily understood that the rearward liner part 18 can be pivoted away from the forward liner part 16, by reason of the inherent resiliency of the material from which the liner is constructed, for insertion of the wearers foot into the boot.
  • a cuff member 22 is secured to the forward part 4 of the shell by means of a rivet 24.
  • the cuff 22 includes an extended strap portion 26 (see FIG. 6) which wraps around the upper part of the shell and which carries a mount 28 to which is secured a cable loop 30.
  • the cable loop 30 is engageable with buckle 32 mounted on the cuff 22 and forward portion 4 of the boot.
  • the buckle 32 is of conventional construction and is adjustable to several settings whereby the circumferential dimension of the strap can be varied to accommodate different foot and leg sizes.
  • the front portion 4 of the shell terminates at an upper edge 34 which is high enough to overlie the lower part of the lower leg of the wearer.
  • the rearward portion 8 of the shell terminates at a like upper edge 36.
  • FIG. 2 illustrates the relation of the strap extension 26 with the upper edges 34 and 36 of the shell parts.
  • FIGS. 3-5 there is shown the upper portion of the front part 4 of the shell of the boot.
  • the portion shown underlies the cuff 22.
  • a vertical slit or cut 38 is formed in the shell portion 4, which cut 38 extends at one end through the upper edge 34 of the portion 4, and terminates at the other end in a circular cut out 40.
  • the shell material in the area of the cut 38 is relatively thin and relatively flexible.
  • the cut 38 forms opposing edges or surfaces which can be spread apart from each other.
  • a wedge member 42 shaped generally like an inverted keyhole is provided to extend or increase the effective circumferential length of the upper.
  • the wedge 42 includes a circular portion 44 sized to fit snugly within the cut out 40, and a radially extending portion 46 which fits between the spread edges of the cut 38, as shown in FIG. 5.
  • the lateral dimension D of the radial portion 46 of the wedge 42 can be varied by providing a plurality of different wedges all having the same size circular part but each having a radial part with a different lateral dimension D. In this manner the extent to which the length of the upper edge 34 of the shell portion 4 is increased can be varied. It will be readily appreciated that the cuff 22 overlying the wedge 42 will prevent the wedge from being accidentally dislodged from the cut out 40 and slit 38.
  • FIGS. 6 and 7 illustrate the manner in which the invention operates.
  • FIG. 6 shows the boot with no wedge inserted in the slit 38. It will be noted that the opposite faces of the slit 38 are in abutment and the circumferential length of the upper edge 34 of the front shell part 4 is at its minimum.
  • the buckle 32 is set at a predetermined setting so that the combined length of cuff 22, strap 26, and cable 30 is set at a given value. It will be noted that the buckled cable pulls the rearward shell I part 8 into nesting relation within the forward shell part 4. As the rearward shell part 8 is pulled into nesting relation with the forward shell part 4, the rearward part 8 is pivoted about the pins 10 so as to establish a minimum forward lean angle for the boot.
  • the minimum forward lean angle of the boot can be changed by pulling the rearward shell part further into the forward shell part, and thus causing the rearward shell part to pivot further forwardly about the pins 10.
  • This increase in nesting is accomplished by inserting a wedge 42 into the cut out 40 and slit 38 so as to force the side surfaces of the slit 38 away from each other. Insertion of the wedge 42 increases the effective length of the upper edge 34 of the front part 4 of the shell by a distance equal to D.
  • the cuff 22, strap 26 and cable 30 are then rebuckled at the same setting as before, as shown in FIG.
  • the cuff 22, strap 26 and cable 30 define a predetermined circumferential length at the given buckle setting, and more of that predetermined length is needed to overlie the now increased dimension of the upper edge 34 of the front part 4 of the shell, the upper edge 36 of the rear part 8 of the shell is pulled further into the front part 4 to increase the minimum forward lean angle of the boot.
  • the minimum forward lean angle of the boot of this invention can be easily varied between any number of given values within a predetermined range to adapt the boot for different types of skiing.
  • a ski boot comprising a first portion which, when the boot is worn, surrounds a lower portion of the lower leg of the wearer, and a second portion which receives the foot of the wearer, said first portion comprising:
  • said first means comprises at least one strap and buckle assembly secured to said front part and encircling said rear part.
  • said opening includes an open cut-out portion and a slit extending from said cut-out portion through said upper terminal edge of said front part.
