4. A ski boot in accordance with claim 3 wherein said holding means comprises a lever defining a plurality of teeth, the loop in said band being first engaged with one of said teeth, said lever then being pivoted into a locked position, and said ends of the band being thereafter adjusted to complete the securing operation.
5. In a ski boot having opposed portions which are opened for insertion of the foot and having securing means for securing said portions after the boot is in place on the foot of the wearer, the improvement wherein said securing means comprise a band extending between said portions, holding means attached to each of said portions with the ends of said band being secured thereto, at least one of said ends defining a threaded surface and internally threaded means associated with at least one of said holding means for receiving aid threaded end whereby the relative positions of said ends can be adjusted, said internally threaded member comprising a nut carried by said one end with the position of said nut on said end being adjustable, one of said holding means comprising a bifurcated member adapted to releasibly hold said nut, sand means for drawing said band taut between said holding means.
6. A ski boot in accordance with claim 5 wherein the other end of said band opposite said threaded end is releasibly held by a holding means.
7. A ski boot in accordance with claim 6 including a tongue secured to said boot, the edges of said opposed sections being located in spaced apart relationship with said tongue being located between said portions, said portions overlapping the sides of said tongue whereby the edges of said portions are drawn closer together when said band is drawn taut whereby a seal is created between said portions and said tongue.
8. A ski boot in accordance with claim 7 including an ankle section having opposed portions defining edged located in spaced-apart relationship, said tongue extending between said ankle portions, and wherein additional securing means are attached to said ankle portions.
9. In a ski boot having opposed portions which are opened for insertion of the foot and having securing means for securing said portions after the boot is in place on the foot of the wearer, the improvement wherein said securing means comprise a band extending between said portions, holding means attached to each of said portions with the ends of said band being secured thereto, at least one of said ends defining a threaded surface and internally threaded means associated with at least one of said holding means for receiving said threaded end whereby the relative positions of said ends can be adjusted, said one holding means comprising a lever member, and an internally threaded member pivotally connected to said lever member for receiving said threaded end, and means for drawing said band taut between said holding means.
10. A ski boot in accordance with claim 9 wherein the pivot axis for said internally threaded member is located at an intermediate point on said lever arm whereby the pivot axis of said internally threaded member will change from one side to the other of the axis of said lever member during pivoting of the lever member.
11. In a ski boot including a sole and heel portion and an upper portion, said upper portion including a pivotally connected ankle section, a movement limiting device associated with said upper portion for determining the extent of allowable pivotal movement of said ankle section, and means associated with said limiting device for adjusting the allowable extent of pivotal movement whereby the limiting device can be set to provide substantial freedom of movement or to substantially reduce the capacity for movement, said limiting device comprising a tongue extending downwardly from said ankle section, a receiving area for said tongue defined by the adjacent upper portion, said tongue being movable relative to said receiving area, and adjustable means for limiting the extent of movement of said tongue relative to the receiving area, the improvement wherein said limiting device comprises a clip, said clip having spaced apart arms, a slot defined by said tongue for receiving at least one of said arms, openings defined by said receiving area whereby at least one of said arms is adapted to pass through at least one opening for receipt of said one arm within said slot whereby movement of the tongue relative to the receiving area will bring the portions of the slot into engagement with the arm whereby the arm serves to limit movement of the tongue.
12. A ski boot in accordance with claim 11 wherein both arms of the clip are simultaneously received within said slot with one of said aRms limiting movement of the tongue in one direction and with the other arm limiting movement of the tongue in the opposite direction.
13. A ski boot in accordance with claim 12 wherein one of said arms is received within said slot with the other arm being located outside the receiving area whereby only said one arm serves to limit movement of the tongue.
14. A ski boot in accordance with claim 13 wherein said tongue defines a wall portion at the bottom end of said slot, one of the arms of said clip being received in said slot adjacent said wall portion and the other arm of said clip being located on the opposite side of said wall portion whereby said wall portion is confined by the arms so that the clip restricts movement of the tongue relative to the receiving area in either direction.
15. In a ski boot having opposed portions which are opened for insertion of the foot and having securing means for securing said portions after the boot is in place on the foot of the wearer, the improvement wherein said securing means comprise a band extending between said portions, holding means attached to each of said portions with the ends of said band being secured thereto, at least one of said ends defining a threaded surface and internally threaded means associated with at least one of said holding means for receiving said threaded end whereby the relative positions of said ends can be adjusted, the other end of said band opposite said threaded end being releasibly held by the other holding means, said other holding means comprising a bifurcated member, and including an enlarged head attached to said other end adapted to be releasibly engaged by said bifurcated member to thereby hold said other end in position when said band is drawing taut between said holding means, and means for drawing said band taut between said holding means.
16. In a ski boot having opposed portions which are opened for insertion of the foot and having securing means for securing said portions after the boot is in place on the foot of the wearer, the improvement wherein said securing means comprise a band extending between said portions, holding means attached to each of said portions with the ends of said band being secured thereto, at least one of said ends defining a threaded surface and internally threaded means associated with at least one of said holding means for receiving said threaded end whereby the relative positions of said ends can be adjusted, means for drawing said band taut between said holding means, a tongue secured to said boot, the edges of said opposed portions being located in spaced apart relationship with said tongue being located between said portions, said portions overlapping the sides of said tongue whereby the edges of said portions are drawn closer together when said band is drawn taut whereby a seal is created between said portions and said tongue, an ankle section having opposed portions defining edges located in spaced-apart relationship, said tongue extending between said ankle portions, and wherein additional securing means are attached to said ankle portions, and wherein said tongue comprises an elongated main body portion, a first stiffener associated with said body portion for overlying the foot of the wearer, and a second stiffener associated with said body portion for overlying the ankle of the wearer, and a flexible area of said body portion located between said stiffeners.
17. In a ski boot having opposed portions which are opened for insertion of the foot and having securing means for securing said portions after the boot is in place on the foot of the wearer, the improvement wherein said securing means comprise a band extending between said portions, said band comprising an internal member of high tensile strength, and a coil spring surrounding said internal member, the turns of said coil spring providing a threaded structure, holding means attached to each of said portions with the ends of said band being secured thereto, internally threaded means associated with at least one of said holding means for receiving one threaded end of said band whereby the relative positions of said ends can be adjusted, and means for drawing said band taut between said holding means.
