Skiboot

Claim 2

In a skiboot of the type possessing a sole and a one-piece upper extending at least to the height of the ankle and formed of a flexurally stiff material, the improvement comprising a flap member for bridging the rear portion of the upper edge of the upper and destined to bear against the leg of the user, means for pivotably attaching said flap member to said upper so as to be pivotable about a pivot axis extending substantially transverse to the lengthwise direction of the skiboot and substantially parallel to the sole of the boot, a cutout formed at the rear portion of the upper edge of the upper, and said flap member bridging said cutout.

Claim 3

The skiboot as defined in claim 1, wherein said cutout is laterally bounded by side edges, said flap member having terminal end portions which overlap said side edges of said cutout at the inside of said upper.

Claim 4

The skiboot as defined in claim 1, wherein said cutout is bounded by a marginal edge portion, said flap member overlapping said marginal edge portion of said cutout at the inside of said upper.

Claim 5

The skiboot as defined in claim 1, wherein said flap member is formed of a bendable nonelastic material.

Claim 6

The skiboot as defined in claim 1, wherein said means for pivotably connecting said flap member to said upper serves to detachably pivotably connect one end of said flap member with said upper.

Claim 7

The skiboot as defined in claim 1, wherein said cutout possesses a substantially U-shaped configuration, and wherein said pivotably attaching means comprise pivot pins arranged substantially at the height of the lowest point of said cutout.

Claim 8

The skiboot as defined in claim 3, wherein said flap member is provided with lateral marginal end portions which overlap the marginal edge portion of said cutout at the inside of said upper, said marginal end portions of said flap member running out to approximately zero thickness, said marginal end portions of said flap member displaceably bearing against the inside of said upper in a sealing-lip fashion.

Claim 9

In a skiboot of the type possessing a sole and a one-piece upper extending at least to the height of the ankle and formed of a flexurally stiff material, the improvement comprising a flap member for bridging the rear portion of the upper edge of the upper and destined to bear against the leg of the user, means for pivotably attaching said flap member to said upper so as to be pivotable about a pivot axis extending substantially transverse to the lengthwise direction of the skiboot and substantially parallel to the sole of the boot, an articulated link, means for pivotably connecting said flap member with said articulated link, and means for pivotably connecting said articulated link to a rear section of the upper edge of said upper.

Claim 10

In a skiboot of the type possessing a sole and a one-piece upper extending at least to the height of the ankle and formed of a flexurally stiff material, the improvement comprising a flap member for bridging the rear portion of the upper edge of the upper and destined to bear against the leg of the user, means for pivotably attaching said flap member to said upper so as to be pivotable about a pivot axis extending substantially transverse to the lengthwise direction of the skiboot and substantially parallel to the sole of the boot, an articulated link, means for pivotably connecting said flap member with said articulated link, and means for pivotably connecting said articulated link to a rear section of the upper edge of said upper.

Claim 11

The skiboot as defined in claim 8, further including stop means for regulating the range of pivoting of said articulated link.

Claim 12

The skiboot as defined in claim 8, further including means for adjusting the elevational position of said flap member with respect to said upper.

Claim 13

The skiboot as defined in claim 10, wherein said adjusting means comprises guide groove means provided at said flap member, and a plate member pivotably supported by said articulated link and engagable with said guide groove means.

Claim 14

The skiboot as defined in claim 8, wherein the lower end of said flap member overlaps the rear section of the upper edge of the upper at the inside of the upper.

Claim 15

The skiboot as defined in claim 8, wherein said means for pivotably connecting said articulated link with the upper edge of said upper comprises an elongate plate member attached to the rear of the upper, said elongate plate member extending from the region of the upper edge of the upper to the region of approximately the heel portion of the boot.

Claim 16

The skiboot as defined in claim 13, wherein said elongate plate member is riveted to thE rear of the boot.

Claim 17

In a skiboot of the type possessing a sole and a one-piece upper extending at least to the height of the ankle and formed of a flexurally stiff material, the improvement comprising a flap member for bridging only the rear portion of the upper edge of the upper and destined to bear only against a rear portion of the leg of the user, and means for pivotably attaching said flap member to said upper so as to be pivotable about a pivot axis extending substantially transverse to the lengthwise direction of the skiboot and substantially parallel to the sole of the boot.

Claim 18

In a skiboot of the type possessing a sole and a one-piece upper extending at least to the height of the ankle and formed of a flexurally stiff material, the improvement comprising a flap member for bridging only the rear portion of the upper edge of the upper and destined to bear only against a rear portion of the leg of the user, and means for pivotably attaching said flap member to said upper so as to be pivotable about a pivot axis extending substantially transverse to the lengthwise direction of the skiboot and substantially parallel to the sole of the boot.
