Abstract: An ice skate with interchangeable blades. The ice skate comprises a body defining a seat for housing a blade-holder to be clamped against the body, and a plurality of sets of blades and respective blade-holders, in which at least the blades of the sets have different geometrical configurations and each set of a blade and a blade-holder is interchangeably replaceable in the seat of the body so that blades of different geometrical configurations can be mounted on the skate, preferably in order to use the skate for different disciplines.

Abstract: A device for adjusting and clamping the toothed strap of a fastening for sports footwear comprises a base, a stopping ratchet mechanism with a first lever for engaging the teeth of the strap in order to stop it, and an advancing ratchet mechanism with a second lever for engaging the teeth of the strap in order to advance it, in which the second lever of the advancing ratchet mechanism is articulated to the first lever of the stopping ratchet mechanism.

Abstract: A skate structure for in-line roller skates includes front and rear blocks adapted to be connected to the toe portion and the heel portion, respectively of a skate shoe. A pair of elongated wheel support frame members are slidably connected to opposite sides of the front and rear blocks and a plurality of in-line wheels are rotatably supported between the frame members. The slidable connection between the frame members and the blocks is provided by a pair of longitudinally extending grooves formed in opposite sides of each of the front and rear blocks and an inwardly extending appendage on each of the frame members. The grooves and appendages have a mating configuration which will prevent lateral separation of the frame members from the blocks while permitting longitudinal sliding movement of the blocks relative to each other on the frame members to accommodate different size skate shoes prior to securing the blocks to the frame members.

Abstract: A device for clamping the toothed strap of a fastening for sports footwear comprises a base and a stop ratchet mechanism including a pawl which is articulated to the base and can engage the teeth of the strap in order to stop it, and a second-order lever articulated to the base and acting on the paw to move it away from and towards a position of engagement with the teeth of the strap.

Abstract: A carrier for an in-line roller skate comprises an elongate body (8) which is to support a series of wheels (5) which are aligned with one another and have respective axes (9) parallel to and spaced from one another. The carrier (3) includes removable suspension means (13) which are interposed between the elongate body (8) and each of the wheels (5) and which can be fastened to the elongate body (8) in a plurality of predetermined positions (15) in order to permit variation in the distance between the wheels (5).

Abstract: The ski-boot fastening described has a device for adjusting the fastening tension, in which a slide operated by male-and-female screw means supports the pin which connects the engagement element to the tensioning lever of the fastening.
