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.

1. 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 lower frame part and the upper frame part hingedly to each other, which hinge is situated
1. 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 lower frame part and the upper frame part hingedly to each other, which hinge is situated at a distance above a 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 lower frame part and the upper frame part have a smallest possible mutual distance;wherein the hinge comprises a ball joint, andwherein 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 upward and downward as well as a lateral pivoting movement relative to the lower frame part. 2. The frame as claimed in claim 1, wherein the resetting means are adjustable. 3. The frame as claimed in claim 2, wherein the resetting means comprises at least one spring, a length and thereby the resilient bias of which can be adjusted continuously or in steps. 4. The frame as claimed in claim 1, wherein a time required by the resetting means to reset the lower frame part and the upper frame part from a maximum angular displacement in the first free degree of freedom or in the second free degree of freedom to mutual rest position amounts to a maximum of 400 ms. 5. The frame as claimed in claim 1, wherein a time required by the resetting means to reset the lower frame part and the upper frame part from a maximum angular displacement in the first free degree of freedom or in the second free degree of freedom to mutual rest position amounts to 300 ms. 6. The frame as claimed in claim 1, wherein the positioning means comprises: a block with a generally V-shaped, narrowing recess present on the one of the lower frame part or the upper frame part; anda protrusion co-acting therewith present on the other of the lower frame part or the upper frame part. 7. The frame as claimed in claim 1, comprising a damping means for damping a shock which occurs during a displacement by the resetting means of the lower frame part to the rest position relative to the upper frame part. 8. The frame as claimed in claim 7, wherein the damping means comprises a block of rubber or a rubber-like material with a hardness in the order of magnitude of (90±20) Shore A. 9. The frame as claimed in claim 1, comprising a first bounding means for bounding an angular displacement in the first free degree of freedom to a maximum of 25°. 10. The frame as claimed in claim 9, comprising a first bounding means for bounding an angular displacement in the first free degree of freedom to about 20°. 11. The frame as claimed in claim 1, comprising a second bounding means for bounding an angular displacement in the second free degree of freedom to a maximum of 50°. 12. The frame as claimed in claim 11, comprising a second bounding means for bounding an angular displacement in the second free degree of freedom to about 40°. 13. A clap skate, comprising a skate shoe and a frame as claimed in claim 1 coupled to the sole and the heel thereof. 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 lower frame part and the upper frame part hingedly to each other, which hinge is situated at a distance above a 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 lower frame part and the upper frame part have a smallest possible mutual distance;wherein the hinge takes a cardan form, andwherein 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 upward and downward as well as a lateral pivoting movement relative to the lower frame part. 15. The frame as claimed in claim 14, wherein the resetting means are adjustable. 16. The frame as claimed in claim 15, wherein the resetting means comprises at least one spring, a length and thereby the resilient bias of which can be adjusted continuously or in steps. 17. The frame as claimed in claim 14, wherein a time required by the resetting means to reset the lower frame part and the upper frame part from a maximum angular displacement in the first free degree of freedom or in the second free degree of freedom to a mutual rest position amounts to a maximum of 400 ms. 18. The frame as claimed in claim 14, wherein a time required by the resetting means to reset the lower frame part and the upper frame part from a maximum angular displacement in the first free degree of freedom or in the second free degree of freedom to mutual rest position amounts to 300 ms. 19. The frame as claimed in claim 14, wherein the positioning means comprises: a block with a generally V-shaped, narrowing recess present on the one of the lower frame part or the upper frame part; anda protrusion co-acting therewith present on the other of the lower frame part or the upper frame part. 20. The frame as claimed in claim 14, comprising a damping means for damping a shock which occurs during a displacement by the resetting means of the lower frame part to the rest position relative to the upper frame part. 21. The frame as claimed in claim 20, wherein the damping means comprises a block of rubber or a rubber-like material with a hardness in the order of magnitude of (90+20) Shore A. 22.
