Abstract
A frame for a clap skate comprises: a lower frame part; an upper frame part with means for coupling to the sole and heel of a skate shoe; hinge which couples the two frame parts hingedly to each other and which are situated at a distance above the foremost zone of the lower frame part and define a first free degree of freedom of rotation, or a plane varying a maximum of about 30° therefrom of the runner; and resetting means for urging the upper frame part to a rest position determined by positioning means, in which rest position the frame parts have the smallest possible mutual distance. The hinge defines a second free degree of freedom of ±30° perpendicularly of the first free degree of freedom. The upper frame part performs an up and downward and lateral pivoting movement relative to the lower frame part.

14. A frame for a clap skate, which frame comprises:
-
a lower frame part for carrying a runner or wheels; an upper frame part with means for coupling to a sole and a heel of a skate shoe; a hinge which couples the two frame parts hingedly to each other, which hinge is situated at a distance above the foremost zone of the lower frame part and defines a first free degree of freedom of rotation in a main plane, or a plane varying a maximum of about 30°
therefrom, of the runner or the wheels; anda resetting means for urging the upper frame part relative to the lower frame part to a rest position determined by a positioning means, in which rest position the frame parts have a smallest possible mutual distance; wherein the hinge defines a second free degree of freedom of rotation within a range of ±
30°
perpendicularly of the first free degree of freedom, such that the upper frame part can perform an up and downward as well as a lateral pivoting movement relative to the lower frame part. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
