Definitions

  • a ski boot comprises a lower shell enclosing major parts of a foot and an upper shell in the form of an ankle cuff pivoted to the lower shell and movable back and forth.
  • the boot has means for adjusting forward inclinations of the upper shell provided obliquely between the front surface of the upper shell and the upper surface of the lower shell.
  • This invention relates to a ski boot which provides positive foot control, and more particularly to a ski boot comprising a lower shell and an upper shell both made of rigid material, wherein the upper shell, in the form of an ankle cuff, is connected to the lower shell, which lower shell is movable in the forwardly and rearwardly inclined positions.
  • a ski boot comprising an outer shell made of light and rigid materials such as plastics or metals, and an inner boot positioned within the outer shell which conforms the boot to a users foot.
  • Such a ski boot is advantageous because it firmly secures the users foot to the ski without lateral and futile movements which are undesirable for positive ski control.
  • the ski boot has to allow the users ankle to pivotally move to its forwardly and rearwardly inclined positions, which are the natural skiing attitudes.
  • the outer shell comprises a lower shell enclosing major parts of a foot and an upper shell in the form of an ankle cuff pivotally connected to the lower shell.
  • the shells open at their front or side portions to allow the users foot to be inserted therein. Therefore, while skiing, snow may pile on the closed portion and enter the shell as the closed portion is directly exposed to snow.
  • the shells are constructed to open at their front portions, the users toe has to be inclined forwardly about his ankle to insert his foot to the shells, such insertion being troublesome especiallywhen the user wears thick.
  • an objective of the present invention is to provide a ski boot in which forward inclinations of an upper shell in the form of an ankle cuff to a lower shell can be easily and visually adjusted to conform to inclinations of slopes to be skied.
  • Another objective of the present invention is to provide a ski boot, as defined above, in which a skier's foot can be easily inserted into the boot from the back thereof.
  • a further objective of the present invention is to provide a ski boot which guards a user's ankle from injuries, such as sprain or fracture, even when the user forcefully falls down forwardly.
  • Another objective of the present invention is to provide a ski boot which is very convenient to carry.
  • a ski boot comprises a rigid lower shell enclosing major parts of a foot, a rigid upper shell in the form of an ankle cuff, means connecting the upper shell to the lower shell to move said upper shell to forwardly and rearwardly inclined positions, and means connected obliquely between the front surface of the upper shell and the upper surface of the lower shell for adjusting forward inclinations of the upper shell.
  • FIG. 1 is a partially sectioned perspective view of a ski boot according to a first embodiment of the present invention, in which rear portions of an upper shell are open;
  • FIG. 2 is a side view of the ski boot shown in FIG. 1 in which the rear portion of the upper shell is closed;
  • FIG. 3 is a back view of the ski boot shown in FIG. 2;
  • FIG. 4 is a partially sectioned side view showing upper portions of an upper shell of a ski boot according to another embodiment of the present invention.
  • a ski boot 1 has a lower shell 2 and an upper shell separated into a front shell 3 and a rear closure shell 6.
  • the lower shell 2 is integrally made of rigid materials such as fiber reinforced plastic, aluminum alloy or the like and is formed on a sole 4 integrally therewith. As shown in the drawings, the lower shell 2 encloses the major portions of a users foot.
  • the upper front shell 3 and rear closure shell 6 are also made of rigid materials, such as mentioned above.
  • the front upper shell 3 encircles and holds substantially the front half of the upper portions of a users ankle and lower portions of a users shin.
  • the rear closure shell 6 when closed, encircles and holds substantially the rear half of the upper portions of a users ankle and the lower portions of a users calf.
  • the front upper shell 3 and the rear closure shell 6 form the upper shell in the form of an ankle cuff.
  • the front upper shell 3 and the rear closure shell 6 are pivotally connected to the upper portion of the lower shell 4 by pivots 9 so that the rear closure shell 6 may be outside of the front upper shell 3.
  • an elastic sheet member 14 is adhered at its both ends to the shells 2 and 3 to close an opening between them, thus serving to preventsnow from entering into the shells 2 and 3 while skiing.
  • heel supporting shell 5 pivotally moves back and forth between them.
  • the inner free end of the heel supporting shell 5 contacts to and closes the rear free end of the front upper shell 3 when the rear closure shell 6 is rotated forwardly about the pivots 9.
  • the rearward rotation of the heel supporting shell 5 is restricted by the inner surface of the rear closure shell 6 which is substantially horizontal inits rearwardly rotated position.
  • the heel supporting shell 5 is provided at its outer surface with two spaced projections 8 which are snugly fitted into recesses 10 formed in the inner surface of the rear closure shell 6 when the latter closes the rear opening of the front upper shell 3. Therefore, the heel supporting shell is prevented from lateral movements.
  • the rear closure shell 6 is clamped to the front upper shell 3 by known clamping members 11 and 12 fixed on the side surfaces of the rear closure shell 6 and the front upper shell 3, respectively.
  • the shell 2 is means for adjusting forward inclinations of the front upper shell 3.
  • the adjusting means comprises a screw rod 19 connected at its one end to the front surface of the upper shell 3 and another screw rod 18 connected at its one end to the upper surface of the lower shell 2, both screw rods 18 and 19 being threaded in the opposite directions and connected to the shells 2 and 3, respectively, by ball joints (universal joints).
  • the screw rods 18 and 19 are threaded into cylindrical cap members 16a and 16 at their other ends, respectively.
  • the cylindrical member 16 is reduced at its free end which encloses an enlarged free end of the other cylindrical member 16a which diameter is smaller than that of the cylindrical member 16.
  • a compression spring 15 is provided which both ends are received by annular synthetic rubbers l7 surrounding, with a slight space, the screw rods 18 and 19. The inner ends of the screw rods 18 and 19 pass through the annular synthetic rubbers 17 and partially pass into the compression spring 15.
  • the cylindrical cap members 16 and 16a are normally urged to be separated from one another, though not disengaged with each other by the enlarged and reduced free ends thereof. But, when a forward thrust is applied to the front upper shell 3, the cylindrical cap member 16 slides forwardly to enclose the opposite cylindrical cap member 16a and, thereby, compresses the spring. 15. Further, when an abnormal forward thrust strong enough to fully compress the springylS is applied, the annular synthetic rubber 17 is compressed after the compression of the spring and, thereby, absorbs the dangerous forward thrust.
  • the cylindrical cap members 16 and 16a are respectively threaded by the screw rods 19 and 18 threaded in the opposite directions, so that the rotation of the cylindrical cap members 16 and 16a in either direction increases or decreases the degree of forward inclination of the upper shell 3.
  • the rear closure shell 6 has an elastic calf supporting member 6a attached to the upper end thereof.
  • the calf supporting member 6a' is made of soft synthetic resin plate, so that the user does not feel pain on his calf even when he wears the boot for a long time in skiing. Except for this point, the second embodiment is substantially the same as the first embodiment.
  • the ski boot according to the present invention is so constructed that the forward inclinations of the upper shell are adjustable by operating the cylindrical cap members 16 and 160 so as to conform to the inclinations of the slopes to be skied.
  • the synthetic rubber is such that it will become compressed after the spring 15 is fully compressed, so that dangerous forward thrust is positively absorbed by the synthetic rubbers 17.
  • the upper shell is opened and closed at its rear portion, not only is the insertion of a users foot into the boot easy but also snow will not come into the boot, while skiing, through connecting portions of the front upper shell 3 and the rear closure shell 6.
  • the boot can easily be carried by gripping the cylindrical cap members or by inserting a ski pole between the cap members 16 and 16a and the elastic sheet member 14.
  • the rear upper end of the upper shell is made of soft synthetic resin plate 60, the user will not feel pain on his calf even when he wears the boot for a long time.
  • a ski boot comprising a rigid lower shell enclosing major portions of a foot, a rigid upper shell in the form of a shell enclosing an ankle, means connecting said upper shell to said lower shell and permitting their relative movement so that the upper shell inclines toward and away from the lower shell, and an adjustment means obliquely extended between the front-surface of said upper shell and the upper surface of said lower shell, said adjustment means adjusting the forward inclination of the upper shell and being compressible by a forward inclined movement of said upper shell.
  • a ski boot as claimed in'claim 8 wherein said forward inclinations adjusting means comprises a first rod connected at its one end to the front surface of said upper shell by a universal joint, a second rod connected at its one end to the upper surface of said lower shell by a universal joint, and a resilient adjusting means interconnecting the other ends of said first and second rods and threaded to at least one of said rods to restrict a rearward inclined movement of said upper shell.
