<p>A roller skate arrangement, which comprises a rigid sole portion (12) to which there is secured on the top side of a shoe upper portion (11) and on the under side a forward and rear wheel pair or wheel bogies (23a, 26a). The wheels (23a, 26a) of each wheel pair can be adjusted to different distances from the sole portion (12) in order to permit oblique positioning of the sole portion (12) sideways relative to the road surface. The wheels (23a, 26a) of the rear wheel pair are pivotable about a first pivotal axis (17a) at right angles to the main plane of the sole portion (12), while the wheels of the forward wheel pair are pivotable about a second pivotal axis at right angles to the main plane of the sole portion. Control means (35, 36; 37, 38; 39, 40) which are arranged between the sole portion (12) and the respective wheel pair, ensures positive control of the turning of at least the one wheel pair about the associated pivotal axis relative to the sole portion, preferably positive control of the turning of the rear wheel pair about the first pivotal axis (17a) relative to the sole portion and sectional positive control of the turning of the forward wheel pair about the second pivotal axis (18a) relative to the sole portion.</p> |
