Abstract: A blade for ice skating having a transverse, longitudinally extending passageway, desirably centrally located, and at least one longitudinally extending structural configuration for securely and partially embedding the blade in a supporting body that is in turn affixed to a shoe. The longitudinally extending passageway and member avoid the structural weaknesses of the prior art and permit the rigid and partial embedding of the blade in the supporting body.

Abstract: A skate blade is fastened to the sole of a skating shoe by means of a screw which extends from inside the shoe through aligned apertures in a recessed washer, the sole of the shoe, the skate blade attaching plate, a body of elastically deformable material located in a hollow support disposed between the plate and the blade and a nut secured to said elastically deformable material. A similar screw nut arrangement is provided at the heel of the skate.

Abstract: A lacing device for ski boots comprises a hooked lever-like lacing member provided on one flap of the boot which cooperates with a ring-like lacing member provided on the other flap of the boot. The hooked lever-like lacing member is hingedly mounted on a carrier plate which is provided with an aperture presenting such a contour as to pass snugly over the enlarged head portion of an anchoring projection obtained on the ski boot flap. The carrier plate is then locked in place by means of a locking bolt, in the form of a small plate hingedly mounted on the carrier plate, which engages one of the recessed portions which form the enlarged head of the anchoring projection. In this manner, the aperture of the carrier plate is practically restricted in its area, and the carrier plate (and lever-like lacing member carried thereby) is secured to the ski boot flap.

Abstract: The lacing device for ski boots comprises a hooked lever-like lacing member which cooperates with a flexible elastic ring-like lacing member. In order to secure the ring-like lacing member to the flap of the ski boot upper, on the flap there is provided a projection which is substantially shaped, in plan view, as a "filled U" and presents a side groove along the "U" outline. A locking element is provided, which consists of a U-shaped plate formed so as to define a correspondingly U-shaped channel, inside which there is housed a portion of the ring-like lacing member, prior to the engagement of the U-shaped plate into the groove provided on the projection. Thus, upon engagement of the locking element plate inside the groove of the projection, a portion of the ring-like lacing member results to be encased in the tubular channel defined by the groove and by the locking element. Anchoring means are provided in order to avoid accidental disengagement of the locking member from the groove.

Abstract: A lacing device for ski boots comprises a hooked lever-like lacing member provided on one flap of the boot which cooperates with a ring-like lacing member provided on the other flap of the boot. The said lacing members are anchored to the boot flaps by providing on the said flaps a corresponding number of projections presenting an enlarged head. An elastic open ring made of steel wire is divaricated by its end portions, which are coaxially directed the one towards the other, so that it can be inserted around the corresponding projection on the flap. The divaricated end portions of the ring are then released so as to close towards each other, and penetrate into borings or side cavities provided at the extremities of the lacing members, thus ensuring an articulated anchoring of the said lacing members to the boot flap.

Abstract: The lacing device for ski boots comprises a hooked lever-like member which cooperates with a ring-like member. Each lacing member is hingedly mounted on a carrier plate which can be slidably fitted on a slide guide element provided on the flap of the ski boot upper. Each slide guide element presents a plurality of notches which can be engaged by a locking tooth provided on a locking lever which is hingedly mounted on the carrier plate. It is therefore possible to adjust the position of the carrier plate, and of the lacing member carried thereby, on the slide guide element, and, after having adjusted said position, to lock the carrier plate so as to avoid any accidental displacement of same.
