Abstract

A skate includes a midskate hinge in the shoe to preferentially flex the shoe base at the metatarsal area, a forward hinge to allow the rear of the shoe to be raised in relation to the rear of the skate frame, and a third hinge to laterally stabilize the rear of the shoe as the shoe base is flexed.

Claims

1. A skate, comprising:

(a) a shoe having a shoe base defining a front and back shoe base portion;

(b) a binding member defining a front and back portion, wherein the front portion of the shoe base is connected to the front portion of the binding member;

(c) a frame defining a front and back frame portion, wherein the frame supports gliding means, and the front portion of the frame is connected to the front portion of the binding member;

(d) a first hinge between the front shoe base portion and the back shoe base portion to permit the back of the shoe to be raised in relation to the back of the binding member;

(e) a second hinge between the front of the binding member and the front of the frame to permit the back of the binding member to be raised in relation to the back of the frame; and

(f) a third hinge located between the back of the shoe base and the back of the binding member to stabilize the back of the shoe as the back of the shoe is raised in relation to the back of the binding member.

2. The skate of claim 1, wherein the skate comprises a front and rear shoe base portion connected to one another via a midskate hinge.

3. The skate of claim 1, wherein the skate comprises a shoe base that preferentially flexes at the metatarsal area.

4. The skate of claim 1, wherein the skate comprises a shoe base having a transverse elongated aperture at about the metatarsal area to preferentially flex the shoe base at the metatarsal area.

5. The skate of claim 1, wherein the skate comprises a shoe base having a unitary base with a reduced thickness at about the metatarsal area to preferentially flex the shoe base at the metatarsal area.

6. The skate of claim 1, wherein the skate comprises a shoe base having an elongated transversely positioned aperture at about the metatarsal area to preferentially flex the shoe base at the metatarsal area.

7. The skate of claim 1, wherein the skate comprises a shoe base having an elastomeric or composite bellows-type joint at about the metatarsal area to preferentially flex the shoe base at the metatarsal area.

8. The skate of claim 1, wherein the gliding means comprise a plurality of in-line wheels or a blade.

9. The skate of claim 1, wherein the third hinge comprises a first and second arm, wherein one arm connects to the back of the binding member, one arm connects to the back of the shoe base, and the first and second arms are connected to each other.

23. The skate of claim 1, wherein the skate is configured to flex at the first hinge before the second hinge.

10. A klap skate, comprising:

a frame having one or more gliding means for traversing across a surface;

a shoe with a shoe base attached to the frame via a klap frame member;

the shoe base preferentially flexes at about the metatarsal area so that the shoe base flexes to create a first separation distance between the klap frame member and the shoe base, wherein the rear of the shoe base is connected to the rear of the klap frame member; and

the klap frame member extending generally the length of the shoe base and pivotably attached to the front of the frame so that the klap frame member pivots to create a second separation distance between the frame and the klap frame member, wherein the separation of the rear of the shoe base with the frame is the combined first and second separation distances.

11. The skate of claim 10, wherein the skate comprises a front and rear shoe base portion connected to one another via a midskate hinge.

12. The skate of claim 10, wherein the shoe base flexes before the klap frame member pivots.

13. The skate of claim 10, wherein the shoe base includes a transverse elongated aperture at about the metatarsal area to preferentially flex the shoe base at the metatarsal area.

14. The skate of claim 10, wherein the shoe base comprises a unitary base with a reduced thickness at about the metatarsal area to preferentially flex the shoe base at the metatarsal area.

15. The skate of claim 10, wherein the shoe base includes an elongated transversely positioned aperture at about the metatarsal area to preferentially flex the shoe base at the metatarsal area.

16. The skate of claim 10, wherein the shoe base comprises an clastomcric or composite bellows-type joint at about the metatarsal area to preferentially flex the shoe base at the metatarsal area.

17. The skate of claim 10, wherein the gliding means comprise a plurality of in-line wheels or a blade.

18. The skate of claim 10, further comprising a hinge having a first and second arm, wherein one arm connects to the back of the klap frame member, one arm connects to the back of the shoe base, and the first and second arms are connected to each other.

21. The skate of claim 13, wherein the back of the shoe base and the back of the klap frame member are connected to each other.

24. The skate of claim 10, wherein the skate is configured to flex at the metatarsal area before pivoting of the klap frame member.

19. An ice skate, comprising:

(a) a shoe that preferentially flexes at about the metatarsal area;

(b) a frame that supports a blade;

(c) a pivoting member that is connected to the front of the frame, and wherein the front of the shoe is connected to the front of the pivoting member; and

(d) a linkage that connects the back of the shoe to the back of the pivoting member.

20. A skate, comprising:

(a) a shoe having a shoe base defining a front and back shoe base portion;

(b) a binding member defining a front and back portion, wherein the front portion of the shoe base is connected to the front portion of the binding member;

(c) a frame defining a front and back frame portion, wherein the frame supports gliding means, and the front portion of the frame is connected to the front portion of the binding member;

(d) a first hinge between the front shoe base portion and the back shoe base portion to permit the back of the shoe to be raised in relation to the back of the binding member;

(e) a second hinge between the front of the binding member and the front of the frame to permit the back of the binding member to be raised in relation to the back of the frame; and

(f) wherein the first hinge is configured to preferentially flex a predetermined amount before substantial flexing of second hinge occurs.

22. A method for sequencing the operation of a double-hinged skate having a midskate hinge that allows flexing of the shoe base at the metatarsal region, and a forward hinge that allows pivoting of a binding plate on which the shoe rests, the method comprising connecting the rear of the shoe base to the binding plate to limit the amount of flex at the shoe base metatarsal region to allow raising the rear of the shoe base from a resting position to a raised position in relation to the rear of the binding plate before allowing pivoting of the binding plate from a resting position to a raised position.
