Abstract

An ice skate comprising an ice skate blade holder and an ice skate blade secured in a longitudinal recess of the ice skate blade holder. The ice skate blade has an ice contacting lower and upper curvatures so as to be positionally changeable in one of two alternative working positions with respect to the ice skate blade holder, wherein the ice skate blade is attached. The ice skate blade has also substantially parallel, opposed side surfaces intersected by at least two longitudinally spaced apart apertures coinciding with at least two longitudinally spaced apart, transversal openings in the ice skate blade holder. Use is made of restraining means inserted through at least two longitudinally spaced apart apertures and at least two longitudinally spaced apart, transversal openings, so as secure together the ice skate blade holder and the ice skate blade.

Claims

1. An ice skate comprising

an ice skate blade holder;

and

an ice skate blade removably secured in a longitudinal recess of said ice skate blade holder, a front and a back end portions of said ice skate blade holder being curved adjacent to the extremities of said longitudinal recess as to protect, during a use of said ice skate, both ends of said ice skate blade, said longitudinal recess being also provided with two sides, designed to be in contact with two opposed side surfaces of said ice skate blade, each one of said two sides incorporating at least two longitudinally spaced apart, transversal openings, so disposed in each one of said two sides as to be coaxial;

said ice skate blade having

an ice contacting lower curvature and an ice contacting upper curvature so as to be positionally changeable in one of two alternative working positions with respect to said ice skate blade holder, wherein said ice skate blade is secured; and

said two opposed side surfaces are penetrated by at least two longitudinally spaced apart apertures coinciding with said at least two longitudinally spaced apart, transversal openings; and

restraining means inserted through said at least two longitudinally spaced apart apertures and said at least two longitudinally spaced apart, transversal openings, so as secure together said ice skate blade holder and said ice skate blade.

2. An ice skate blade adapted to be used with an ice skate blade holder provided with a longitudinal recess, wherein said ice skate blade is removably secured, said longitudinal recess having two sides designed to be in contact with two opposed side surfaces of said ice skate blade, each one of said two sides incorporating at least two longitudinally spaced apart, transversal openings, so disposed in each one of said two sides as to be coaxial;

said ice skate blade comprising

an ice contacting lower curvature and an ice contacting upper curvature so as to be positionally changeable in one of two alternative working positions with respect to said ice skate blade holder; and

a pair of parallel, opposed side surfaces transversally penetrated by at least two longitudinally spaced apart apertures coinciding with said at least two longitudinally spaced apart, transversal openings.

3. An ice skate comprising

an ice skate blade holder;

and

an ice skate blade removably secured in a longitudinal recess of said ice skate blade holder, a front and a back end portions of said ice skate blade holder being curved adjacent to the extremities of said longitudinal recess as to protect, during the use of said ice skate, both of said ice skate blade, said longitudinal recess being also provided with two sides designed to be in contact with two opposed side surfaces of said ice skate blade, each one of said two sides incorporating at least two longitudinally spaced apart, transversal openings, so disposed in each one of said two sides as to be coaxial;

said ice skate blade being defined geometrically by a longitudinal axis of symmetry, intersected centrally by a transversal axis of symmetry, said ice skate blade being provided with a lower curvature, symmetrical to and identical with an upper curvature;

said ice skate blade being also provided with a first front-to-rear extending edge forming an ice-contacting edge, and a second front-to-rear extending edge/also forming an ice-contacting edge/, spaced and substantially parallel to said first front-to-rear extending edge, said lower and upper curvatures having each a bow-shape, so said ice skate blade'"'"'s configuration is similar to an ellipse with elongated ends;

said ice skate blade having also substantially parallel, opposed side surfaces transversally penetrated by at least two longitudinally spaced apart apertures disposed to coincide with at least two longitudinally spaced apart, transversal openings of said longitudinal recess; and

restraining means inserted through said at least two longitudinally spaced apart apertures and said at least two longitudinally spaced apart, transversal openings, so as secure together said ice skate blade holder and said ice skate blade.

4. An ice skate blade adapted to be used with an ice skate blade holder including a longitudinal recess wherein said ice skate blade is removably secured, said longitudinal recess having two sides designed to be in contact with said ice skate blade, each one of said two opposed sides incorporating at least two longitudinally spaced apart transversal openings, so disposed in each one of said two opposed sides as to be coaxial,

said ice skate blade being defined geometrically by a longitudinal axis of symmetry, intersected centrally by a transversal axis of symmetry, said ice skate blade being provided with a lower curvature, symmetrical to and identical with an upper curvature;

said ice skate blade having a first front-to-rear extending edge, forming an ice-contacting edge, and a second front-to-rear extending edge/forming also an ice-contacting edge/, spaced and substantially parallel to said first front-to rear extending edge, said lower and upper curvatures having each a bow-shape, so said ice skate blade'"'"'s configuration is similar to an ellipse with elongated ends; and

said ice skate blade having also substantially parallel, opposed side surfaces transversally penetrated by at least two longitudinally spaced apart apertures disposed to coincide with at least two longitudinally spaced apart transversal openings of said longitudinal recess.
