<p>The invention relates to a roller skate (1) comprising a sub-frame (3) intended for the bearing of a shoe (5); at least one rear wheel (26, 27) situated at the rear side of the sub-frame (3) and connected thereto; a pair of mutually tracking front wheels (17, 18) which are attached for free turning to a rocking arm (21) that is rigid in a sideways direction and connected for rocking to the front side of the sub-frame (3); and a brake member (35, 36) which is attached to the sub-frame such that forward tilting of the sub-frame (3) results in the brake member (35) making contact with the rearmost front wheel (18). In preference on a rocking arm the distance from the rocking arm-rotation point to a foremost wheel (a) is greater than the distance to the rearmost wheel (b).</p> |
