Abstract

A protective covering is provided having a central protective plate portion and a terminal edge portion encircling the central protective plate portion. A coupling region is interposed between the terminal edge portion and the central protective plate portion. The coupling region transitions from a pliable material of the terminal edge portion to a rigid material of the central protective plate portion, where the coupling region extends from a first edge to a second edge. The first edge has a higher concentration of the pliable material than the rigid material and the second edge has a higher concentration of the rigid material than the pliable material. A first surface of the coupling region has a higher concentration of the pliable material than the rigid material and a second surface of the coupling region has a higher concentration of the rigid material than the pliable material.

First claim

What is claimed is:

1. An athletic guard comprising: a central protective plate portion comprising a rigid material; a terminal edge portion at least partially encircling the central protective plate portion, the terminal edge portion comprising a pliable material of lower rigidity than the rigid material; and a coupling region comprising a graded interface, the coupling region transitioning from the pliable material of the terminal edge portion to the rigid material of the central protective plate portion, wherein the graded interface extends across the coupling region from a first edge to a second edge of the coupling region and from a first surface to a second surface of the coupling region, the graded interface forming a first acute angle with the first surface of the coupling region and a second acute angle with the second surface of the coupling region, the first edge comprising the pliable material and the second edge comprising the rigid material, the first surface being the rigid material and the second surface being the pliable material, wherein the first surface opposes the second surface over the length of the graded interface.

2. The athletic guard of claim 1 , wherein the coupling region at least partially encircles the central protective plate portion.

3. The athletic guard of claim 1 , wherein the terminal edge portion completely encircles the central protective plate portion.

4. The athletic guard of claim 1 , wherein the coupling region is chemically and mechanically attaching the terminal edge portion and the central protective plate portion.

5. The athletic guard of claim 1 , wherein the pliable material of the terminal edge portion and the rigid material of the central protective plate portion are chemically cross-linked across the coupling region.

6. The athletic guard of claim 1 , wherein the second surface of the coupling region is substantially continuous with a second surface of the terminal edge portion.

7. The athletic guard of claim 1 , wherein the first surface of the coupling region is substantially continuous with a second surface of the central protective plate portion.

8. The athletic guard of claim 1 , wherein the terminal edge portion extends into a flared lip.

9. The athletic guard of claim 1 , wherein the terminal edge portion comprises a rounded terminal.

10. The athletic guard of claim 1 , wherein the central protective plate portion has at least one convex extent and at least one concave extent along a cross section that is perpendicular to a first surface thereof.

11. The athletic guard of claim 1 , wherein the rigid material is a semi-rigid flexible polymer and the pliable material is a polymer.

12. An athletic guard comprising: a rigid protective plate portion; a pliable edge portion surrounding the rigid protective plate portion, the pliable edge portion being of lower rigidity than the rigid protective plate portion; and a coupling region comprising a graded interface, the pliable edge portion and the rigid protective plate portion being chemically cross-linked across the coupling region, in which a first material forming the pliable edge portion transitions into a second material forming the rigid protective plate portion, the graded interface extending across the coupling region from a first edge to a second edge of the coupling region and from a first surface to a second surface of the coupling region, the graded interface forming a first acute angle with the first surface of the coupling region and a second acute angle with the second surface of the coupling region, the first edge comprising the first material and the second edge comprising the second material, the first surface being the first material and the second surface being the second material wherein the first surface opposes the second surface over the length of the graded interface.

13. The athletic guard of claim 12 , wherein the pliable edge portion is co-molded with the rigid protective plate portion.

14. The athletic guard of claim 12 , wherein the coupling region surrounds the rigid protective plate portion.

15. The athletic guard of claim 12 , wherein the first surface of the coupling region is substantially continuous with a first surface of the pliable edge portion and the second surface of the coupling region is substantially continuous with a second surface of the rigid protective plate portion.

16. A protective covering comprising:
a protective plate portion constructed of a rigid material, the protective plate portion comprising a medial plate portion and a lateral plate portion when in an as-worn position;
a terminal edge portion surrounding the protective plate portion, the terminal edge portion constructed of a pliable material of lower rigidity than the rigid material; and
a coupling region comprising a graded interface interposed between the protective plate portion and the terminal edge portion, the coupling region chemically and physically attaching the terminal edge portion to the protective plate portion, the coupling region transitioning from the pliable material of the terminal edge portion to the rigid material of the protective plate portion, wherein the graded interface extends from a first edge to a second edge of the coupling region and from a first surface to a second surface of the coupling region, the graded interface forming a first acute angle with the first surface of the coupling region and a second acute angle with the second surface of the coupling region, the first edge comprising the pliable material and the second edge comprising the rigid material, the first surface being the rigid material and the second surface being the pliable material, wherein the first surface opposes the second surface over the graded interface.

17. The protective covering of claim 16 , wherein the protective plate portion has at least one convex extent between a concave extent in the medial plate portion and a concave extent in the lateral plate portion.

18. The protective covering of claim 16 , wherein the protective plate portion comprises a contact groove defined by outer edges of the medial plate portion and the lateral plate portion.

19. The protective covering of claim 16 , wherein the coupling region surrounds the protective plate portion coextensively with the terminal edge portion.
