Abstract

A variety of devices for protecting a user's foot from injury are disclosed. In one embodiment, the device may be a metatarsal protection device, which may include a first layer of material having top and bottom surfaces, with at least one of such surfaces including a series of cones or a pattern of hexagons thereon. The metatarsal protection device may also include a second relatively rigid layer of material overlying the first layer, and the first layer may be shaped to conform to the metatarsal region of the user's foot, such that the device is configured to protect the metatarsal region against injury. Other configurations and variations of a metatarsal protection device are also disclosed, as are other uses for the principles of the invention(s) disclosed herein (e.g., protection devices for other areas of the foot, etc).

First claim

The invention claimed is:

1. An article of apparel, comprising:
a housing sized to retain a protection device, the housing being arranged adjacent a portion of a body of a user; and
a protection device positioned within the housing, the protection device comprising:
a first layer of material having first and second opposing surfaces and a series of frustum-shaped recesses formed along at least one of the first and second surfaces, wherein the series of frustum-shaped recesses includes a first frustum-shaped recess with a first depth and width and a second frustum-shaped recess with a second, different depth and width; and
a second layer of material attached to the first layer and having a rigidity that is higher than a rigidity of the first layer, the first layer being shaped to conform to the portion of the user's body, such that the protection device is arranged to provide protection for the portion of the user's body against injurious events.

2. An article of apparel according to claim 1 , wherein a first set of the first and second frustum-shaped recesses alternate along a lateral axis of the protection device, and a second set of the first and second frustum-shaped recesses alternate along a longitudinal axis of the protection device.

3. An article of apparel according to claim 1 , wherein the first frustum-shaped recess is formed along the first surface of the first layer of material, and the second frustum-shaped recess is formed along the second surface of the first layer of material, the second frustum-shaped recess being inverted with respect to the first frustum-shaped recess.

4. An article of apparel according to claim 3 , wherein the first and second frustum-shaped recesses are defined by a generally frustoconical region terminating in a circular end, and the circular end of the first frustum-shaped recess is adjacent the circular end of the second frustum-shaped recess.

5. An article of apparel according to claim 1 , wherein each of the frustum-shaped recesses has a substantially continuous internal wall surface defining the frustum shape thereof.

6. An article of apparel according to claim 1 , wherein the series of frustum-shaped recesses includes a pattern of hexagonal-shaped recesses.

7. An article of apparel according to claim 6 , wherein each hexagonal-shaped recess comprises an inner hexagonal-shaped recess that is surrounded by an outer hexagon, the outer hexagon including walls extending alongside the inner hexagonal-shaped recess.

8. An article of apparel according to claim 1 , wherein the second layer of material has first and second opposing surfaces and a series of frustum-shaped recesses are formed along at least one of the first and second surfaces.

9. An article of apparel according to claim 1 , wherein the protection device is selected from the group consisting of a metatarsal guard for a shoe, a foot guard for protection of a portion of the user's foot, a knee guard, and an elbow guard.

10. An article of apparel according to claim 1 , wherein the frustum-shaped recesses have a shape selected from the group consisting of a frustum of a cone and a hexagonal prism.

11. An article of apparel, comprising:
a housing sized to retain a protection device, the housing being arranged adjacent a portion of a body of a user; and
a protection device positioned within the housing, the protection device comprising first and second layers of material, the second layer of material being attached to the first layer of material and having a rigidity that is higher than a rigidity of the first layer, wherein the second layer of material includes first and second opposing surfaces, and a series of frustum-shaped recesses is formed along at least one of the first and second surfaces, the first layer of material being shaped to conform to a portion of a user's body to provide protection against injurious events.

12. An article of apparel according to claim 11 , wherein each of the frustum-shaped recesses has a substantially continuous internal wall surface defining the frustum shape thereof.

13. An article of apparel according to claim 11 , wherein the frustum-shaped recesses have a shape selected from the group consisting of a frustum of a cone and a hexagonal prism.

14. An article of apparel according to claim 11 , wherein the first layer of material includes first and second opposing surfaces and a series of frustum-shaped recesses is formed along at least one of the first and second surfaces.

15. An article of apparel according to claim 14 , wherein at least one of the series of frustum-shaped recesses formed along the first layer of material and the series of frustum-shaped recesses formed along the second layer of material includes a series of recesses in which each of the recesses is shaped as a hexagonal prism.

16. An article of apparel according to claim 11 , wherein the second layer of material exhibits rigidity when bent in a first direction, and reacts with relative flexibility when bent in a second, opposing direction.

17. An article of apparel according to claim 11 , wherein the frustum-shaped recesses are formed along the second surface of the second layer of material.

18. An article of apparel according to claim 11 , wherein the protection device is selected from the group consisting of a metatarsal guard for a shoe, a foot guard for protection of a portion of the user's foot, a knee guard, and an elbow guard.

19. An article of apparel, comprising:
a protection device comprising first and second layers of material, the second layer of material being attached to the first layer of material and having a rigidity that is higher than a rigidity of the first layer, wherein the first and second layers of material each includes first and second opposing surfaces, respectively, and a series of frustum-shaped recesses is formed along at least one of the first and second surfaces of either the first or the second layer of material, wherein the series of frustum-shaped recesses includes a first frustum-shaped recess with a first depth and width and a second frustum-shaped recess with a second, different depth and width, the first layer of material being shaped to conform to a portion of a user's body to provide protection against injurious events.

20. An article of apparel according to claim 19 , further comprising a housing sized to retain the protection device, the housing being arranged adjacent a portion of a body of the user, wherein the protection device is positioned within the housing.

21. An article of apparel according to claim 19 , wherein the protection device is selected from the group consisting of a metatarsal guard for a shoe, a foot guard for protection of a portion of the user's foot, a knee guard, and an elbow guard.

22. An article of apparel according to claim 19 , wherein each of the frustum-shaped recesses has a substantially continuous internal wall surface defining the frustum shape thereof.

23. An article of apparel according to claim 19 , wherein each of the first and second layers of material includes a series of frustum-shaped recesses formed along at least one of the first and second opposing surfaces thereof.
