Definitions

• the present invention relates to sport shoes in general and more specifically to a dynamic internal fitting system for a sport shoe as disclosed in applicant's above identified co-pending applications.
• a sport shoe in the nature of a ski boot.
• the upper cuff member is movably coupled to the lower shell member for forward and rearward movement in a plane parallel to the longitudinal axis of the boot.
• a means for engaging the instep and forefoot of a skier's foot such as, for example, a pair of strap members.
• the footengaging means is coupled to the movable cuff member by a cable coupled to a pulley which is in turn coupled to the cuff member.
• a movable foot bed located in the interior of a rigid shell of a ski boot.
• the foot bed is coupled to a movable cuff member.
• the movable foot bed is raised and lowered for adjusting the fit of the ski boot to a foot enclosed therein. in both of the embodiments described a movable cuff member is employed for dynamically changing the fit of the sport shoe relative to a foot enclosed thereby.
• movable cuff members are rigidly attached to or formed as a rigid extension of a lower shell member. Turns and other forceful skiing maneuvers are accomplished by a skier leaning into the forward part of the cuff member. Ordinarily there is no movable part in the ski boot which moves significantly in response to the forward and rearward lean.
• the fitting system means responsve to lower extremity movement which is separate from the cuff member for dynamically adjusting the fit of the fitting system.
• a principal object of the present invention is a dynamic internal fitting system for a sport shoe for dynamically momentarily tightening the fit of the sport shoe without requiring a cuff to open and close the mechanism.
• Another object of the present invention is a sport shoe in which there is provided means for engaging a foot and means coupled to the foot-engaging means for adjusting the position of the foot-engaging means relative to a foot engaged thereby in response to movement of the leg to which the foot is attached.
• Another object of the present invention is a sport shoe as described above in which there is provided a means for tightening the fit of the sport shoe in response to a forward movement of a leg relative to a foot attached thereto.
• Another object of the present invention is a sport shoe as described above in which there is provided a rigid assembly including a rigid member which extends downwardly a predetermined distance from a location above the ankle to a position in the bottom of the sport shoe and means for coupling the rigid assembly to the foot-engaging means, said rigid assembly being movable in response to movement of a leg relative to a foot attached thereto.
• a dynamic internal fitting system for a sport shoe which may be used in sport shoes including boots with and without cuff members.
• This permits boots to be made with cuff members of varying styles and operation such as front and rear opening cuff members and cuff members with varying degrees of movement from rigid to extreme forward and rearward flex.
• the invention may be used in sport shoes which do not normally have a cuff such as running and hockey shoes.
• Fig. 1 is a side elevation view of a sport shoe in the nature of a ski boot according to the present invention.
• Fig. 2 is a side cross-sectional view of a sport shoe according to the present invention.
• Fig. 3 is a front cross-sectional view of a flex bar according to the present invention.
• a sport shoe in the form of a ski boot designated generally as 1.
• the cuff member 3 is movably mounted to the shell member 2 as by a rivet pin 4. It should be understood, however, that the cuff member 3 could be rigidly attached in a non-movable manner to the lower shell 2 as the movement of the cuff 3 relative to the shell 2 forms no part of the present invention.
• the present invention as will be seen, may be employed in a sport shoe without any cuff member at all.
• a foot-engaging means designated generally as 5 a lower extremity-engaging means designated generally as 6 , means for movably mounting the lower extremityengaging means in the sport shoe designated generally as 7 and coupling means designated generally as 8 for coupling the lower extremity-engaging means 6 and said foot-engaging means 5.
• a liner designated generally as 9 typically fabricated from relatively soft, pliable rubber-like material.
• leg-engaging means 6 there is provided a curved, generally rectangularly shaped section forming a shinengaging means 10. Extending from the ends of the shin engaging means 10 there is provided a pair of rigid arm members 11 and 12.
• the lower extremity-engaging means 6 is movably mounted to the sport shoe 1 by means of the movable mounting means 7 and a corresponding mounting means in the form of a rivet or the like 13.
• the adjusting knob 17 and the stud 15 are provided for attaching the pulley member 16 to the bottom of the arm 11 in a friction-tight manner.
• a pair of strap members 20 and 21 In the foot-engaging means 5 there is provided a pair of strap members 20 and 21. One end of the strap member 20 is attached to the foot bed of the sport shoe 1 in the ball of the foot area. The corresponding end of the strap member 21 is attached to the foot bed of the sport shoe 1 in the heel area. Both of the strap members 20 and 21 extend from their point of attachment to the foot bed of the shoe 1 over the instep portion of a foot to a linking member 22. The opposite ends of the strap members 20 and 21 are movably connected to opposite ends of the linking member 22. Between the strap members 20 and 21 the linking member 22 is attached to the pulley member 16 by a cable means 23.
• the lower extremity-engaging means 6 In operation, during forward leaning of a leg relative to a foot enclosed by the foot-engaging means 5, the lower extremity-engaging means 6 is moved forwardly about the axis of the mounting means 7. As the lower extremity-engaging means 6 is moved about the axis of the mounting means 7, the pulley 16 is rotated in a counter-clockwise direction placing a tension on the cable means 23 and pulling on the straps 20 and 21. As the straps 20 and 21 are pulled, the fit of the foot-engaging means 5 is tightened relative to a foot engaged thereby.
• the adjusting knob 17 in the mounting means 7 is loosened and the arms 11 and 12 moved in a clockwise or counter-clockwise direction as desired.
• the knob member 17 is tightened, securing the position of the lower extremity engaging means 6 with respect to the pulley member 16. While an embodiment of the present invention is shown and described, it is contemplated that various modifi cations to the embodiment described may be made without departing from the spirit and scope of the present invention.
• the arms 11 and 12 and the member 10 may be formed for engaging the calf of a leg with a strap or the like provided for removably attaching the member 10 to the leg's calf.
• strap means attached to a leg may, by cable and suitable pulley means attached to the front and rear margins of the cuff of a sport shoe, be coupled to the pulley 16 for moving the pulley 16 and consequently the foot-engaging means 5 as a leg is moved fore and aft relative to a foot attached thereby.
• the means for moving the foot-engaging means 5 is independent of any existing cuff member such as the cuff member 3 and may be employed in a sport shoe without any cuff member. Accordingly it is intended that the embodiments described and the suggested modifications thereto be employed solely for purposes of illustrating the present invention and that the scope of the present invention be determined solely by reference to the claims hereinafter provided and their equivalents.
