Abstract

The invention relates to a plastic ski boot produced by injection moulding of the type having an outer shell and inner padding. A boot is described wherein the shape of the outer shell is symmetrical about a central longitudinal plane and therefore adapted for use as either the right or left foot boot of a pair; the right or left foot shape being imparted interiorly of the shell by suitably contoured padding.

Claims

1. A ski boot having a plastic outer shell comprising:

a substantially rigid sub-shell having an outer sole and an upper covering a foot to above the ankle region of the foot, said outer shell being internally and externally generally symmetrical about its central longitudinal plane and being identical foR both boots of a pair, a padding in said outer shell adapted to the shape of a foot, an entry aperture in said upper extending as far as the top edge thereof, and adapted to be closed by a cover forming a part of said upper;

said cover being substantially rigid and forming the remainder of said upper and being adapted to be placed and locked over said entry aperture;

said sub-shell forming the rear part of said upper and in the instep area of said sub-shell, the cover is pivotable about an axis perpendicular to the central longitudinal plane.

2. The ski boot according to claim 1, wherein said cover is locked to the sub-shell by means of a substantially U-shaped yoke embracing the rear part of the upper, the forward-facing ends of the legs of the said yoke being hinged to the cover, while a point of the middle portion of each leg thereof is hinged to a link, the said links, located on each side of the sub-shell, being pivotable about axes perpendicular to the central longitudinal plane.

3. The ski boot according to claim 1, wherein a supporting shell, embracing the foot from behind, pivots on the sub-shell about an axis perpendicular to the central longitudinal plane and is adapted to be locked in a position determining the forward-lean of the wearer.

4. The ski boot according to claim 2, wherein a supporting shell, embracing the foot from behind, pivots on the sub-shell about an axis perpendicular to the central longitudinal plane and is adapted to be locked by said yoke simultaneously with the closing of said cover.

5. The ski boot according to claim 4, wherein each of said links are connected to said sub-shell by means of a disc carrying an eccentric, and said eccentric projecting into a recess in said supporting shell and resting against the edge thereof in such a manner that it pushes the supporting shell forward when said yoke is closed.

6. The ski boot according to claim 3, wherein the said supporting-shell is made from a substantially rigid material and a cam is pivotably supported on the sub-shell passing through an opening in the sub-shell and pressing against the supporting-shell.
