Abstract
A sport shoe (1, 101, 201, 400, 500, 600, 650, 700, 750, 780, 800, 850, 900, 950) is disclosed comprising a dynamic fitting system responsive to wearer movement. In various embodiments of the shoe there is provided movable strap members (17, 19), a movable instep tongue member (163, 263), a movable footbed (412, 516, 605, 705, 784), a movable tongue and heel receiving member (860, 861), adjustable cuff members (701) and interior and exterior tongue assemblies (915, 920). In use the above members in response to wearer movement tighten momentarily the fit of the sport shoe from a close fit.
Claims60
A sport shoe for a lower extremity comprising fitting means for providing a close fit between the shoe and the lower extremity;
- tightening means responsive to a predetermined movement of the wearer of the shoe for momentarily increasing the tightness of the close fit established by the fitting means;
- and means for preventing a loosening of the fitting means.
A sport shoe for a lower extremity comprising a lower shell and an upper cuff movably connected with the shell;
- fitting means providing a close fit between the shoe and the lower extremity when the shell and the cuff are in a first relative position;
- tightening means for tightening the fitting means in response to a relative movement between the upper cuff and the lower shell for momentarily increasing the tightness of the fitting means when the cuff and the shell move with respect to each other from the first position in a first direction;
- and means for preventing a loosening of the fitting means when the cuff and the shell move with respect to each other from the first position in a second direction.
A sport shoe comprising a lower shell, an upper cuff movably attached to the shell;
- at least one strap disposed interiorly of the shoe and located to engage an upper surface of a foot disposed in the shoe means connecting a first end of the strap with the shoe;
- means connecting a second end of the strap with the shoe;
- and means disposed between at least one end of the strap and the shoe for tightening the strap against the foot in response to a predetermined relative movement between the cuff and the shell in a first directon and for loosening the strap in response to a predetermined movement between the shell and the cuff in a second, generally opposite direction.
A sport shoe comprising a lower shell;
- an upper cuff movably attached to the lower shell;
- first and second straps disposed interiorly of the shell for engaging an upper surface of a foot disposed in the shoe;
- means connecting proximate first ends of the straps with the shoe;
- and means connecting second, proximate ends of the straps with the shoe, the second ends connecting means including an elongated link pivotally attached to the second ends of the straps, and a cable having a first end pivotally attached to the link at a point intermediate the points of attachment of the straps, and a second end attached to the shoe so that the straps apply a force against the upper surface of a foot when disposed in the shoe;
- whereby relative movement of one of the straps in response to movement of the lower extremity in the boot increases the force applied by such strap against the foot and pivots the link about the cable attachment point and thereby causes a corresponding increase in the force applied against the foot by the second strap.
A sport shoe comprising a shell for receiving a portion of a lower extremity including a foot and part of a leg and defining a sole of the shoe;
- a generally rigid footbed disposed in the shoe generally above the sole thereof;
- means defining a transverse axis about which the footbed pivots;
- footbed moving means engaging a side of the footbed facing the sole for raising and lowering the footbed relative to the shell to correspondingly increase and decrease the tightness with which the shoe engages the foot;
- and means operatively coupled with the moving means for sensing predetermined movements of the lower extremity and correspondingly activating the moving means to raise and lower the footbed to thereby change the tightness of the fit of the shoe as a function of the predetermined movement of the lower extremity.
A sport shoe comprising a shell and a cuff movably attached to the shell;
- a footbed disposed within the shoe generally above the sole;
- means coupling an aft end of the footbed with the cuff so that relative movement of the cuff in a forward direction raises the aft end of the footbed and thereby temporarily increases the tightness of the fit of the shoe on the foot;
- and means carried by the footbed and the shell for inducing a forward motion of the footbed relative to the shell as a result of the raising of the footbed relative to the shell to thereby further increase the tightness of the fit.
A sport shoe comprising a lower shell including a sole, an upper cuff, means permitting relative pivotal movement between the cuff and the shell about a transverse axis from a rest position towards a position in which the cuff is forwardly inclined relative to its rest position;
- the cuff having a generally tubular configuration and overlapping ends which can be drawn together and pulled apart to correspondingly vary the tightness with which the cuff engages a leg of a lower extremity disposed in the shoe;
- a footbed in the shoe generally above the sole;
- and cable means operatively coupled with the footbed, the shell and the cuff so that relative forward pivotal movement of the cuff raises the footbed with respect to the sole to thereby increase the tightness with which the foot is engaged by the shoe and simultaneously draws together the overlapping ends of the cuff to increase the tightness with which the cuff engages the leg.
A sport shoe comprising a lower shell including a sole;
- an upper cuff pivotally mounted to the shell for pivotal movement from a rest position in a forward direction about an axis extending transversely across the boot;
- a footbed disposed in the shoe generally above the sole;
- cam means disposed between the sole and the footbed and fixed relative to the cuff for pivotal movement therewith and for engaging and raising the footbed relative to the sole during pivotal movement of the cuff in a forward direction;
- and strap means extending across an upper surface of the foot and having ends attached to the shell so that the raising of the footbed increases the force with which the strap engages the foot and thereby temporarily increases the tightness of the fit of the shoe on the foot as a function of the forward movement of the cuff from its rest position.
