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

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 ice skate blade holder, wherein ice skate blade is firmly, but removably attached; and

substantially parallel, opposed side surfaces intersected by at least two longitudinally spaced apart apertures coinciding with at least two longitudinally spaced apart, transversal openings;

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

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

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 ice skate blade holder, wherein ice skate blade is firmly, but removably attached; and

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

ice skate blade being defined geometrically by a longitudinal axis of symmetry, intersected by a transversal axis of symmetry in the center of symmetry of ice skate blade, the latter being provided with a lower curvature, symmetrically identical to an upper curvature;

ice skate blade having a first front-to-rear extending edge, forming an ice-contacting edge, and a second front-to-rear extending edge, spaced and substantially parallel to first front-to-rear extending edge, lower and upper curvatures having each a bow-shape, so that ice skate blade configuration can be considered as similar to an ellipse with elongated ends;

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

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

4. An ice skate blade adapted to be used with an ice skate blade holder provided with a longitudinal recess, wherein ice skate blade is removably secured, longitudinal recess having two sides designed to be in contact with ice skate blade, each one of two opposed sides incorporating at least two longitudinally spaced apart, transversal openings, so disposed in each one of two opposed sides as to be coaxial, ice skate blade being defined geometrically by a longitudinal axis of symmetry, intersected by a transversal axis of symmetry in the center of symmetry of ice skate blade, the latter being provided with a lower curvature, symmetrically identical to an upper curvature;

ice skate blade having a first front-to-rear extending edge, forming an ice-contacting edge, and a second front-to-rear extending edge, spaced and substantially parallel to first front-to rear extending edge, lower and upper curvatures having each a bow-shape, so that ice skate blade configuration can be considered as similar to an ellipse with elongated ends; and

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