DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a ski boot comprising a shell with a sole and a toe cap, which shell holds the foot at least in the instep area, and a shaft surrounding the leg, whereby the shell and toe cap are constructed from one piece of plastic and are pivotally connected with one another by the sole, a recess is provided in the shell rearwardly of the toe cap and extends through the ski boot essentially over its entire width to define the pivoting range of the toe cap, and a cover projecting beyond the rearward edge of the cap to cover the recess and can be moved during pivoting of the toe cap under the instep area of the shell.
A ski boot is, on the one hand, supposed to form an essentially rigid unit in connection with the ski, whereby the toe cap is held in the flat position and the shaft in a forward position; on the other hand, a flexing of the sole is supposed to be possible during walking. A toe cap, which is pivotal relative to the shell, is used for this purpose. When the shell of the ski boot is designed in one piece of plastic, the jointed connection with the toe cap is created through the sole, which in the pivoting range can be bent through a transverse groove.
BASIC STATE OF THE ART
A sports boot is known from PCT WO 92/19117, which includes a pivotal toe cap which for the purpose of a relative mobility with respect to the shell, is hinged with a spacing in the form of a gaplike recess through the sole to the shell. This recess is laterally bridged on both sides by a cover, which moves under the shell during walking. The important, center part of the recess is covered by a deformable insert. The insert is compressed when the toe cap is pivoted in and is expanded when the flat position is reached. The moldable material, like for example a rubber sponge, is highly stressed by coldness, moisture and by a continuous change of the shape so that it tears and consequently sealing problems can result, in particular at the connecting areas of the toe cap on the one side and of the shell on the other side. An operating mechanism in the shell blocks the toe cap during skiing. This blocking can be done through a linkage by means of a trigger on the side of the heel inserted through a binding element, like for example, the heel automatic mechanism.
Furthermore, the AT-PS 356 541 discloses a ski boot formed in one piece and having an inner reinforcing insert. The reinforcing insert is arranged in the area of the sole and consists of two parts connected by a hinge. This ski boot has an elasticity in the toe area, which elasticity depends on the particular design. An individual toe cap can only be locked at the reinforcing insert.
The DE-A1-24 46 066 describes a front-foot heel shell for a ski boot, in which a partial shell receiving the toe-ball portion can be pivoted and locked relative to the remaining shell about a transverse axis positioned on or close to the sole, whereby the dividing edges of the partial shell and of the remaining shell face one another and lie outside of the sole overlapping one another. The free end edge of the cover grips under the shell and where the edging of the shell defines the recess, in at least one area of the free end edge of the cover there are provided bars directed against one another.
Finally, AT-B-379 731 discloses a ski boot having a lower part holding the foot and an upper part holding the leg and is designed as a shaft, the parts are connected by a bellows, whereby the stiffness of the bellows can be varied in the area of its front side by inserting a reinforcing element between the folds of the bellows. The reinforcing element is designed like a serrated slat, the teeth of which engage in the expanded position of the bellows between the folds, preferably designed with a trapezoidal cross section.
DISCLOSURE OF THE INVENTION
The invention has the goal of improving the sealing of a ski boot having a toe cap movable with respect to the shell. This is achieved in a ski boot of the above-mentioned type by the cover, viewed in the longitudinal cros
