1. An ice skate for skating on ice, which comprises;
an upper chassis section comprising a first contact surface having a front end and a rear end,
a lower chassis section comprising a second contact surface having a front end and a rear end, and
a coupling arrangement comprising a spring back means, which coupling arrangement is arranged to mechanically connect the upper and lower chassis sections,
wherein at least one of the first and second contact surfaces is curved;
wherein the coupling arrangement is arranged to allow the upper chassis section to pivot relative to the lower chassis section by rolling contact motion between the first and second contact surface such that a momentary contact region (CR) of the first and second contact surfaces moves back and forth between the front and rear ends of the first and second contact surface,
wherein the spring back means is arranged to apply an urging force between the upper and lower chassis sections for urging the momentary contact region (CR) to a neutral position along the first and second contact surfaces,
wherein the coupling arrangement comprises a release means arranged to be selectively set to a locking position for applying the urging force between the upper and lower chassis sections and a release position for relieving the urging force and allowing the lower chassis section to be removed from the upper chassis section,
wherein the release means comprises the spring back means, and
wherein the spring back means is fixed to the upper chassis section and arranged to be selectively set to be engaged with the lower chassis section for urging the momentary contact region (CR) to the neutral position and to be disengaged from the lower chassis section, for allowing the lower chassis section to be removed from the upper chassis section.
