Abstract

A sporting good implement, such as a hockey stick or ball bat, includes a main body. The main body may be formed from multiple layers of a structural material, such as a fiber-reinforced composite material. One or more microlattice structures may be positioned between layers of the structural material. One or more microlattice structures may additionally or alternatively be used to form the core of a sporting good implement, such as a hockey-stick blade. The microlattice structures improve the performance, strength, or feel of the sporting good implement.

First claim

What is claimed is:

1. A skate comprising:
a first layer and a second layer opposite one another; and
a lattice disposed between and covered by the first layer of the skate and the second layer of the skate;
wherein: the lattice comprises a predefined arrangement of structural members integral with one another and intersecting one another at nodes; respective ones of the nodes of the lattice are spaced apart from one another in three orthogonal directions that include a given direction of the skate from the first layer of the skate to the second layer of the skate; at least one of the first layer of the skate and the second layer of the skate comprises fiber-reinforced polymeric material; and at least one of the first layer of the skate and the second layer of the skate is heat-formable.

2. The skate of claim 1 , comprising a skate boot that comprises the lattice.

3. The skate of claim 1 , wherein a density of the lattice is variable.

4. The skate of claim 1 , wherein a spacing of the structural members of the lattice is variable.

5. The skate of claim 1 , wherein respective ones of the structural members of the lattice vary in size.

6. The skate of claim 1 , wherein respective ones of the structural members of the lattice vary in orientation.

7. The skate of claim 1 , wherein a resistance to compression of the lattice is variable.

8. The skate of claim 1 , wherein a stiffness of the lattice is variable.

9. The skate of claim 1 , wherein a first zone of the lattice is stiffer than a second zone of the lattice.

10. The skate of claim 9 , wherein: a third zone of the lattice is stiffer than the second zone of the lattice; and the second zone of the lattice is disposed between the first zone of the lattice and the third zone of the lattice.

11. The skate of claim 1 , wherein an openness of the lattice is variable.

12. The skate of claim 1 , wherein a first zone of the lattice is more open than a second zone of the lattice.

13. The skate of claim 12 , wherein: a third zone of the lattice is less open than the first zone of the lattice; and the first zone of the lattice is disposed between the second zone of the lattice and the third zone of the lattice.

14. The skate of claim 1 , wherein the lattice occupies at least a majority of a cross-sectional dimension of the skate from the first layer of the skate to the second layer of the skate.

15. The skate of claim 1 , wherein the fiber-reinforced polymeric material is carbon-fiber-reinforced polymeric material.

16. The skate of claim 1 , wherein at least one of the first layer and the second layer comprises textile material.

17. The skate of claim 1 , wherein: the first layer comprises the fiber-reinforced polymeric material; and a material of the second layer is different from the fiber-reinforced polymeric material.

18. The skate of claim 1 , wherein the lattice is curved.

19. The skate of claim 1 , wherein the lattice is polymeric.

20. The skate of claim 19 , wherein the lattice is entirely polymeric.

21. The skate of claim 1 , wherein the lattice is metallic.

22. The skate of claim 1 , comprising filling material that fills at least part of hollow space of the lattice.

23. The skate of claim 22 , wherein the filling material comprises foam.

24. The skate of claim 22 , wherein the filling material comprises elastomeric material.

25. The skate of claim 22 , wherein the filling material is configured to dampen vibrations.

26. The skate of claim 1 , wherein the lattice is optically formed.

27. The skate of claim 26 , wherein the lattice is optically formed by collimated light beams.

28. The skate of claim 26 , wherein the lattice is optically formed by ultraviolet light.

29. The skate of claim 1 , wherein the nodes of the lattice are disposed in at least four levels that are spaced apart from one another in the given direction from the first layer of the skate to the second layer of the skate.

30. The skate of claim 1 , wherein the nodes of the lattice are disposed in at least five levels that are spaced apart from one another in the given direction from the first layer of the skate to the second layer of the skate.

31. The skate of claim 1 , wherein the structural members of the lattice extend in at least five different directions.

32. The skate of claim 1 , wherein the structural members of the lattice extend in a multitude of different directions.

33. The skate of claim 1 , wherein the structural members of the lattice are created and polymerized separately from one another.

34. The skate of claim 1 , wherein the structural members of the lattice comprise struts.

35. A skate comprising a skate boot, wherein the skate boot is configured to enclose a user's foot and comprises:
a first layer and a second layer; and
a lattice disposed between and covered by the first layer and the second layer and comprising a predefined arrangement of structural members integral with one another and intersecting one another at nodes;
wherein: at least one of the first layer and the second layer comprises fiber-reinforced polymeric material; and at least one of the first layer and the second layer is heat-formable.

36. A skate comprising a skate boot, wherein the skate boot is configured to enclose a user's foot and comprises:
a first boot material and a second boot material different from the first boot material; and
a lattice disposed between and covered by the first boot material and the second boot material and comprising a predefined arrangement of structural members integral with one another and intersecting one another at nodes
wherein: at least one of the first boot material and the second boot material is fiber-reinforced; and at least one of the first boot material and the second boot material is heat-formable.
