<p>A training roller skate comprising rollers or wheels and mounting means therefor, the mounting means for at least one wheel being movable, preferably in a direction transverse to the wheel axis, to permit contact between a wheel associated surface and motion inhibiting means that is to inhibit rotary motion of the wheel. The skate has a front shoe part defining a forward platform portion to support a skater's foot and further defining toe cap support means with which a separately formed toe cap is snap-fittedly attached thereby to permit toe caps of alternative shapes and forms (e.g. representing cartoon characters) to be selectively attached to the toe cap support means. The forward platform portion may have attached thereto a brake pad of frictional material that is engageable by a said roller, said brake pad being provided integrally with a projection frictionally to engage the ground when the platform is tilted. At least one of the wheels or rollers has a surface associated therewith provided with at least one projection or recess, and a main body of the skate is provided with at least one recess or projection dimensioned for mating engagement with the (or at least one of the) said surface projection or recess, the mounting means being movable selectively to effect such mating engagement - to inhibit both forwards skating and rearwards skating - and out of such mating engagement - to permit skating in at least the forwards direction. The roller skate may further comprise a forward carriage and a rearward carriage, length adjustment means interconnecting them, and locking means to lock the interconnected first and second carriages in a selected one of a plurality of predetermined relative positions, the locking means comprising, to each side (of the skate's longitudinal central axis): an elongate channel having one side wall thereof formed with a plurality of slot-like openings depending from one of said carriages; and a lock member mounted for pivoting motion on the other of said carriages, said lock member having a first finger to extend through an opening in a wall of said other carriage and abut against the opposite wall of said recess, and having a second finger to extend through the same or another opening in said carriage wall and to engage into a selected one of the slot-like openings. Fastening arrangements are also disclosed comprising a strap having (preferably between edges of the strap) a plurality of recesses in a major surface of the strap; and a buckle having a body member in the form of an arched structure through which the strap is to extend and further having a pawl member disposed between said major surface of the strap - when the latter is in the buckle - and a facing wall of the body member, said pawl member having a tip end for entry into any selected one of said recesses. One of said members is provided with a laterally-extending element (e.g. a rib or a wall), and the other of said members is provided with a laterally-extending channel to accommodate the element and define therewith a pivot axis for the pawl member. Additionally or alternatively, one of said members is molded of plastics material integrally with at least one inherently resilient limb that is engageable either of the strap or, as is preferred, of the other of said members to provide a restoring force countering disengagement of the pawl member from its said state of recess engagement. <IMAGE></p> |
