Abstract

Claims (26)

1. An ice skate blade assembly for a skate, the ice skate blade assembly extending along a longitudinal axis and comprising:

(a) an ice skate blade comprising first and second ends, an ice-contacting surface and an upper edge opposite to the ice-contacting surface, the upper edge comprising first and second hooks projecting upwardly proximate to one of the first and second ends respectively;

(b) a blade holder having first and second pedestals and a bridge portion connecting the first and second pedestals, the blade holder further comprising a bottom portion having a longitudinal groove extending therealong for receiving the upper edge of the ice skate blade, the bottom portion further defining a recess extending upwardly from the longitudinal groove for receiving the first hook of the ice skate blade and wherein the second pedestal has an inner surface defining a cavity with a bottom aperture that opens to the longitudinal groove; and

(c) a single actuator for selectively locking the ice skate blade into the blade holder and releasing the ice skate blade from the blade holder, the single actuator being at least partially mounted within the cavity of the second pedestal and comprising a finger-engaging surface accessible by at least one finger of a user from an exterior of the blade holder and a hook-receiving portion for receiving the second hook of the ice skate blade, the hook-receiving portion being movable between (i) a lock position, in which the hook-receiving portion engages the second hook of the ice skate blade to lock the ice skate blade in the longitudinal groove of the blade holder, and (ii) a release position, in which the hook-receiving portion disengages the second hook of the ice skate blade to release the ice skate blade from the blade holder, and wherein the hook-receiving portion is movable in response to the at least one finger of the user acting on the finger-engaging surface for imparting translation movement of the single actuator from the lock position to the release position.

2. An ice skate blade assembly as defined in claim 1 , wherein the hook-receiving portion comprises an inner wall and a bottom wall with an upper surface, an end and a bottom surface, the inner wall and bottom wall of the hook-receiving portion defining therebetween a channel that opens to the bottom aperture of the second pedestal for receiving the second hook of the ice skate blade.

3. An ice skate blade assembly as defined in claim 2 , wherein, when the first hook is received within the recess and the second hook is received within the channel, the bottom wall of the hook-receiving portion wedges the second hook for locking in place the ice skate blade in the longitudinal groove of the blade holder.

4. An ice skate blade assembly as defined in claim 2 , wherein the second hook has an upper surface, an end and a bottom surface, wherein the single actuator further comprises a resilient portion having an end wall facing a section of the inner surface of the second pedestal, and wherein, when the first hook is received within the recess and the second hook is received within the channel, the bottom wall of the hook-receiving portion wedges the second hook for locking in place the ice skate blade in the longitudinal groove of the blade holder whereby an upward force is applied by the bottom wall of the hook-receiving portion to the bottom surface of the second hook due to a remaining tension in the resilient portion of the single actuator.

5. An ice skate blade assembly as defined in claim 4 , wherein, upon pressure by the user on the finger-engaging surface, the resilient portion is deformed and the translation movement of the single actuator in a first direction is imparted such that the upper surface of the bottom wall of the hook-receiving portion no longer contacts the bottom surface of the second hook and upward force is no longer applied upon the second hook by the bottom wall of the hook-receiving portion such that the second hook can exit the channel of the hook-receiving portion.

6. An ice skate blade assembly as defined in claim 5 , wherein, upon pressure by the user on the finger-engaging surface, the translation movement of the single actuator along the first direction further creates a downward force on the second hook as long as the inner wall of the hook-receiving portion remains in contact with the upper surface of the second hook.

7. An ice skate blade assembly as defined in claim 6 , wherein the single actuator moves in a second direction opposite to the first direction when pressure is no longer applied by the user on the finger-engaging surface.

8. An ice skate blade assembly as defined in claim 7 , wherein the end of the bottom wall of the hook-receiving portion abuts the end of the second hook when the single actuator moves along the second direction such that the bottom wall of the hook-receiving portion applies a downward force on the second hook.

9. An ice skate blade assembly as defined in claim 4 , wherein the end of the second hook is an inclined end and wherein the end of the bottom wall of the hook-receiving portion is an inclined end.

10. An ice skate blade assembly as defined in claim 4 , wherein the inner wall of the hook-receiving portion is an inclined wall extending along a line that defines an angle θ 3 relative to an axis parallel to the longitudinal axis.

11. An ice skate blade assembly as defined in claim 10 , wherein the angle θ 3 is between 35° and 75°.

12. An ice skate blade assembly as defined in claim 11 , wherein the upper surface of the second hook is an inclined upper surface extending along a line that defines an angle θ 4 relative to an axis parallel to the longitudinal axis.

13. An ice skate blade assembly as defined in claim 12 , wherein the angle θ 4 is between 35° and 75°.

14. An ice skate blade as defined in claim 4 , wherein the end of the bottom wall of the hook-receiving portion is an inclined end extending along a line that defines an angle θ 2 relative to an axis parallel to the longitudinal axis.

15. An ice skate blade assembly as defined in claim 14 , wherein the angle θ 2 is between 0° and 90°.

16. An ice skate blade as defined in claim 15 , wherein the end of the second hook is an inclined end extending along a line that defines an angle θ 1 relative to an axis parallel to the longitudinal axis.

17. An ice skate blade assembly as defined in claim 16 , wherein the angle θ 1 is between 90° and 180°.

18. An ice skate blade assembly as defined in claim 4 , wherein the upward force is generally perpendicular to a contacting region between the upper surface of the bottom wall of the hook-receiving portion and the bottom surface of the second hook.

19. An ice skate blade assembly as defined in claim 4 , wherein the upward force extends along a line that defines an angle θ 5 relative to an axis parallel to the longitudinal axis.

20. An ice skate blade assembly as defined in claim 19 , wherein the angle θ 5 is between 25° and 65°.

21. An ice skate blade assembly as defined in claim 1 , wherein the upper edge of the ice skate blade further comprises an upwardly projecting tooth located between the first and second hooks, the tooth having first and second walls extending upwardly from the upper edge and a top wall.

22. An ice skate blade assembly as defined in claim 21 , wherein the bottom portion of the blade holder further defines an indent extending upwardly from the longitudinal groove, the indent having first and second walls extending downwardly and a top wall.

23. An ice skate blade assembly as defined in claim 22 , wherein the indent has an internal profile that generally matches the external profile of the tooth such that one of the first and second walls of the tooth abuts against one of the first and second walls of the indent
