Ski boot

Claim 2

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.

Claim 3

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.

Claim 4

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.

Claim 5

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.

Claim 6

A ski boot as claimed in claim 1, wherein said upper shell comprises a front upper shell and a rear closure shell both pivoted to the upper portion of said lower shell; and a heel closure shell is located between said front upper shell and said rear closure shell and is hinged to the rear upper end of said lower shell, whereby said ski boot can be fully opened at its rear portion to easily insert a user''s foot therein and can be easily closed only by clamping said rear closure shell to said front upper shell.

Claim 7

A ski boot as claimed in claim 2, wherein said other ends of said first and second rods are threaded in the opposite directions; and said resilient adjusting means comprises a first cylindrical cap through a closed end of which said first rod is threaded, a second cylindrical cap through a closed end of which said second rod is threaded, said first and second cylindrical caps being slidably engaged with each other at their free end portions, and a compression spring compressed between said closed ends in said first and second cylindrical caps, whereby when said cylindrical caps are rotated in either direction, the forward inclinations of said upper shell are increased or decreased, and when said upper shell is forwardly inclined by a forward thrust applied to the user''s leg, the cylindrical caps move to the opposite direction by compressing said spring and absorb said forward thrust.

Claim 8

A ski boot as claimed in claim 3, wherein said rear closure shell is provided at its upper end portion with a soft synthetic resin sheet member.

Claim 9

A ski boot as claimed in claim 3, wherein an elastic sheet member is provided to close a space between the lower end of said upper shell and the upper end of said lower shell.
