ROLLER SKATE WITH LONGITUDINALLY ALIGNED WHEELS

Abstract: A roller skate with longitudinally aligned wheels, comprising a boot (2) and a substantially inverted U-shaped frame (10), on the flanges (12) of which there are mounted a plurality of pivot pins (15) for wheels (16), characterised in that the boot is provided lowerly with at least one appendix (6) removably engaging in a corresponding seat (19) provided in the horizontal portion (18) of the U-shaped frame (10), and securely retained by locking means (26) and in that the horizontal portion extends at least on one side into a portion (20) for protecting the lower surface of the sole.

Description: R O L L ER SKATE WITH LONGITUDINALLY ALIGNED WHEELS This invention relates to a roller skate with longitudinally aligned wheels. Roller skates are known consisting of a boot to which there is applied a substantially inverted U-shaped frame, on the flanges of which there are mounted a plurality of pivot pins for plastic wheels. In addition to the normal activity of skating on roads, one of the preferred pastimes of the expert is to skate along the handrial of stairways. In performing this, the skater rests one of the boot sole portions, external to the frame, on the handrail and rests the other skate transversely to the handrail on an arched portion provided in the lower edge of its flanges. A first drawback of this sporting practice is that with the passage of time the boot wears down at the sole, making it practically unserviceabel. Another drawback is that the sole has a high friction coefficient which makes it difficult to slide along the handrail. Another drawback of these skates is the considerable laboriousness of fixing the frame to the boot, this generally being effected by a plurality of rivets which retain the frame by engagin it with the underside of the sole. To this must be added the fact that replacing the frame when worn requires the use of a special tool. A further drawback is that the rivets may cause damage by contact with the handrail surface. Another drawback is that during this sporting activity the skater may accidentally bring the edges of the two facing inner surfaces of the boot into mutual contact, so damaging the surface. All these drawbacks are eliminated according to the invention by a roller skate in accordance with claim 1 The present invention is further clarified hereinafter with reference to the accompanying drawing, in which Figure 1 is an exploded perspective view of a skate according to the invention, and Figure 2 is a cross-section therethrough As can be seen from the figures, the skate according to the invention comprises essentially a boot shell 2 provided with a sole 4 with which two flat appendices 6 provided with a hole 8 are rigid, and a substantially inverted U- shaped frame 10 with its flanges 12 possessing a plurality of holes 14 for supporting the pivot pins 15 for the wheels 16 The frame support base 18 of the frame 10 comprises two slots 19 at a distance apart substantially equal to the distance between the two appendices 6 the dimensions of which are essentially equal to the lenght and width of the slots Said support base 18 extends from both longitudinal edges as two flat portions 20 for covering that part of the sole surface which projects beyond the support surface 18 Said portions then extend as a substantially vertical edge 22, the profile of which substantially follows the contour of the sole, its purpose being to protect the lower side edge 24 of the boot shell 2 The boot shell 2 is fixed to the frame 10 by the engagement of through pins 26 which fix the boot appendices 6 to the frame flanges 12 From the aforegoing it is clear that the accessory according to the invention presents numerous advantages, and in particular - it enables the wheel support frame to be easily replaced without requiring the use of specialized personnel or special tools; it provides considerable protection to the boot against wear by virtue of the projecting portion of the frame; it enables the frame to be replaced by another of different rigidity and/or roughness. it can give the boot a pleasing appearance by being formed in particular chromatic colours and/or by carrying personalized writing.

Claims: C L A I M S 1 A roller skate with longitudinally aligned wheels comprising a boot (2) and a substantially inverted U-shaped frame (10) on the flanges (12) of which there are mounted a plurality of pivot pins (15) for wheels (16), characterised in that the boot is provided lowerly with at least one appendix (6) removalby engaging in a corresponding seat (19) provided in the horizontal portion (18) of the U-shaoed frame (10), and securely retained by locking means (26) and in that the horizontal portion extends at least on one side into a portion (20) for protecting the lower surface of the sole 2 A skate as claimed in claim 1 , characterised in that hte portion (20) consists of a flat portion which extends into a substantially vertical edge (22) for protecting the lower edge (24) of the boot 3 A roller skate as claimed in claim 1 , characterised by comprising two substantially parallelepiped appendices (6) which engage in two corresponding apertures (19) provided in the horizontal surface of the U- shaped frame 4 A roller skate as claimed in claim 1 characterised in that said appendices (6) are locked with respect to the boot (2) through pins (26) engaging also the frame flanges (12)
