Abstract

An improved sports pad for protecting a particular area of a user'"'"'s body and including a relatively rigid, lightweight plate molded to conform to the protected body area, an outer layer of resilient thermoplastic honeycomb padding affixed to the outer surface of the plate, and an inner layer of resilient thermoplastic honeycomb padding affixed to the inner surface of the plate. The outer layer is preferably of a closed-cell configuration while the inner layer is of an open-celled configuration perforated to allow the flow of air from cell to cell.

Claims

1. A sports pad for protecting particular areas of a user'"'"'s body from blunt trauma or similar injury, comprising:

a substantially rigid plate having a lower face and an upper side surface, said plate being formed to fit the curvature of a body surface to be protected;

an outer panel including a first flexible cellular honeycomb core affixed to said upper side surface; and

an inner panel including a second flexible cellular honeycomb core secured to said lower face and adapted to engage a user'"'"'s body, the cell walls of said second core being apertured to allow fluid flow through said cells.

2. A sports pad as recited in claim 1 wherein said plate is formed of a solid layer of plastic material.

3. A sports pad as recited in claim 1 wherein said plate is formed by a rigid honeycomb structure.

4. A sports pad as recited in claim 1 wherein said first honeycomb core has cells extending from a first core face to a second core face, an outer facing sheet affixed to said first core face, and an inner facing sheet affixed to said second core face, said inner and outer facing sheets being operative to close the cells of said first core, said inner facing sheet being bonded to said upper side surface.

5. A sports pad as recited in claim 4 wherein said second honeycomb core has open cells extending between a third core face and a fourth core face, said third core face having a facing sheet bonded thereto and to said lower face, the cells of said second honeycomb core being open at said fourth core face such that there is no facing sheet bonded thereto.

6. A sports pad as recited in claim 1 and further comprising means for affixing the pad to a user'"'"'s body.

7. A sports pad as recited in claim 6 wherein said first honeycomb core has cells extending from a first core face to a second core face, an outer facing sheet affixed to said first core face, and an inner facing sheet affixed to said second core face, said inner and outer facing sheets being operative to close the cells of said first core, said inner facing sheet being bonded to said upper side surface.

8. A sports pad for protecting a particular body part of a user, comprising:

a rigid plate deformed to correspond to the contour of a particular body part to be protected;

a first resilient energy-absorbing panel affixed to one side surface of said plate, said first panel including a honeycomb core; and

a second resilient energy-absorbing panel having a first side affixed to a side surface of said plate opposite said one side surface, and a second side adapted to engage said particular body part, said second panel including a honeycomb core having cells extending between said first and second sides, said cells being closed at said first side and open at said second side.

9. A sports pad as recited in claim 8 wherein the core walls forming said cells are perforated so as to permit fluid flow between adjacent cells.

10. A sports pad as recited in claim 8 wherein said first panel includes a honeycomb core having cells closed on one side by a first facing sheet and closed on an opposite side by a second facing sheet.

11. A sports pad as recited in claim 8 wherein said plate has apertures therein to permit fluid flow therethrough.

12. A sports pad as recited in claim 11 wherein said first panel has apertures formed therein to permit fluid flow therethrough.
