Abstract

A blade holder assembly for a skate including a blade holder having an elongated groove defined in a bottom surface, and a recess extending upwardly therefrom in alignment with a pedestal, for engagement with a blade. The pedestal has an internal cavity defined therein separate and spaced from the elongated groove and the recess. A locking arm is engaged to the pedestal and movable between a locked position and an unlocked position. The locking arm has an engagement end protruding into the recess through an opening defined in a wall of the pedestal. A greater portion of the engagement end protrudes into the recess in the locked position than in the unlocked position. At least a major part of the locking arm, including the engagement end, remains outside of the internal cavity of the pedestal in the locked and unlocked positions. A blade assembly is also discussed.

First claim

The invention claimed is:

1. A blade assembly for a skate, the assembly comprising:
a blade holder including first and second pedestals configured for attachment to the skate, the blade holder having a bottom surface having an elongated groove defined therein, the blade holder having a plurality of recesses defined therein extending upwardly from the elongated groove, the first and second pedestals each having a bottom wall extending above the elongated groove and an internal cavity defined above the bottom wall;
an elongated blade including a body defining an ice-engaging edge, an elongated top edge opposite the ice-engaging edge, and a plurality of projections extending upwardly from the body, the blade and blade holder relatively moveable between an engagement position where the elongated top edge is engaged in the elongated groove and the plurality of projections are each received in a respective one of the recesses, and a disengagement position where the blade is disengaged from the recesses and the elongated groove; and
a locking arm engaged to the holder and movable between a locked position and an unlocked position;
wherein in the locked position, the locking arm has an engagement end engaging the blade through an opening defined in a wall of the holder and maintaining the blade in the engagement position;
wherein in the unlocked position, the locking arm is disengaged from the blade and the blade is movable to the disengagement position; and
wherein a major part of the locking arm including the engagement end remains outside of the internal cavities of the first and second pedestals in the locked and unlocked positions.

2. The blade assembly as defined in claim 1 , wherein the whole locking arm remains outside of the internal cavities of the first and second pedestals in the locked and unlocked positions.

3. The blade assembly as defined in claim 1 , wherein:
the recesses include a first recess defined in the first pedestal and a second recess defined in the second pedestal;
the projections include a first projection received in the first recess and a second projection received in the second recess;
the locking arm is engaged to the first pedestal; and
the engagement end of the locking arm in the locked position engages the first projection through the opening defined in the wall of the first pedestal, the opening communicating with the first recess without communicating with the internal cavity of the first pedestal, the locking arm maintaining the first projection in engagement with the first recess.

4. The blade assembly as defined in claim 3 , wherein in the locked position, the engagement end of the locking arm interlocks with a concave edge of the first projection.

5. The blade assembly as defined in claim 3 , wherein the first pedestal is a rear pedestal.

6. The blade assembly as defined in claim 1 , wherein the locking arm is biased toward the locked position or against movement toward the unlocked position.

7. The blade assembly as defined in claim 1 , wherein the locking arm is movable between the locked and unlocked position by sliding along an outer surface of the wall of the holder.

8. The blade assembly as defined in claim 7 , wherein the locking arm includes two spaced apart legs deformable toward one another, the legs being abutted against a surface of the holder when the locking arm is in the locked position, the legs being receivable through an opening defined in the surface only when deformed toward one another, the locking arm being moveable to the unlocked position through engagement of the deformed legs in the opening, the opening being defined outside of and separate from the internal cavities of the first and second pedestals.

9. The blade assembly as defined in claim 7 , wherein the locking arm is connected to the holder through a deformable end of the locking arm opposite from the engagement end and connected to the holder in a fixed location, the deformable end being reversibly deformed and in a compressed state when the locking arm is in the unlocked position, the deformable end biasing the locking arm toward the locked position.

10. The blade assembly as defined in claim 1 , wherein the locking arm rests against an outer surface of the wall of the holder in the locked position, the locking arm being movable from the locked position to the unlocked position by pivoting away from the outer surface.

11. The blade assembly as defined in claim 1 , wherein the locking arm includes a pin and a threaded sleeve surrounding the pin and threadingly engaged therewith, the threaded sleeve extending outside of the holder such as to be rotatable by a user, the pin of the locking arm including the engagement end, the locking arm being movable between the locked and unlocked positions through rotation of the threaded sleeve causing movement of the pin along a longitudinal axis thereof.

12. A blade holder assembly for a skate, the assembly comprising:
a blade holder having a bottom surface partially defined by a pedestal configured for interconnection with a boot of the skate, the bottom surface of the blade holder having an elongated groove defined therein and a recess extending upwardly from the elongated groove in alignment with the pedestal, the elongated groove configured for removably engaging a top edge of a blade and the recess configured for removably engaging a projection of the blade, the pedestal having an internal cavity defined therein separate and spaced from the elongated groove and the recess; and
a locking arm engaged to the holder and movable between a locked position and an unlocked position, the locking arm including a finger-engaging portion for manipulation by a user;
wherein in the locked position, the locking arm has an engagement end protruding into the recess through an opening defined in a wall of the pedestal, a greater portion of the engagement end protruding into the recess in the locked position than in the unlocked position; and
wherein a major part of the locking arm including the engagement end and the finger-engaging portion remains outside of the internal cavity of the pedestal in the locked and unlocked positions.

13. The blade holder assembly as defined in claim 12 , wherein the whole locking arm remains outside of the internal cavity of the pedestal in the locked and unlocked positions.

14. The blade holder assembly as defined in claim 12 , wherein the locking arm is biased toward the locked position or against movement toward the unlocked position.

15. The blade holder assembly as defined in claim 12 , wherein the locking arm is movable between the locked and unlocked position by sliding along an outer surface of the wall of the pedestal.

16. The blade holder assembly as defined in claim 15 , wherein the locking arm includes two spaced apart legs deformable toward one another, the legs being abutted against a surface of the pedestal when the locking arm is in the locked position, the legs being receivable through an opening defined in the surface only when deformed toward one another, the locking arm being moveable to the unlocked position through engagement of the deformed legs in the opening, the opening being defined outside of and separate from the internal cavity of the pedestal.

17. The blade holder assembly as defined in claim 15 , wherein the locking arm is connected to the pedestal through a deformable end of the locking arm opposite from the engagement end and connected to the pedestal in a fixed location, the deformable end being reversibly deformed and in a compressed state when the locking arm is in the
