Abstract

A face shield for use with protective headgear can be shipped flat and easily assembled from a kit of parts without the use of tools or adhesives. The face shield protects against disease, aerosols and splatter that may contain pathogens; may include a curved lower perimeter to facilitate head movements, and can be taken on and off easily.

First claim

What is claimed is:

1. A kit for a face shield, comprising:
a transparent face covering, the transparent face covering comprising:
a curved perimeter along a bottom edge;
a first plurality of slots located proximate a top edge and a left side outer perimeter;
a second plurality of slots located proximate said top edge and a right side outer perimeter; and,
a first and second set of headband slots; and,

a headband having a plurality of notches sized to mate with said headband slots, the headband adapted to be coupled to an exterior surface of a helmet.

2. The kit of claim 1 , further comprising:
a compression strap sized to fit through said first and said second plurality of slots.

3. The kit of claim 2 , wherein said compression strap comprises elastic.

4. The kit of claim 2 , wherein said compression strap comprises cord.

5. The kit of claim 2 , wherein said compression strap comprises a shoelace.

6. The kit of claim 2 , wherein the compression strap is adapted to wrap around the exterior surface of the helmet, the headband secured to the helmet via the compression of the compression strap wrapped around the exterior surface of the helmet.

7. The kit of claim 1 , wherein said transparent face covering comprises a transparent plastic.

8. The kit of claim 7 , wherein said transparent plastic comprises polycarbonate.

9. The kit of claim 1 , wherein said transparent face covering and said headband comprises polyethylene terephthalate glycol.

10. The kit of claim 1 , wherein said transparent face covering and said headband are formed by additive manufacturing.

11. The kit of claim 1 , wherein said transparent face covering and said headband are formed by injection molding.

12. The kit of claim 1 , wherein said transparent face covering and said headband are formed by laser cutting.

13. The kit of claim 1 , wherein the helmet is selected from a group of helmets consisting of: military helmets, hard hats, speed boat helmets, climbing helmets, spelunking helmets, watercraft helmets, firefighting helmets, helicopter helmets, and hearing protection helmets.

14. The kit of claim 1 , wherein the headband is further adapted to be coupled to the exterior surface of the helmet to include an air gap adapted to provide airflow and prevent fogging of the transparent face covering.

15. The kit of claim 1 , wherein the transparent face covering comprises a flexible material.

16. A method for using a face shield, comprising the steps of:
attaching a headband to a transparent sheet of material, wherein said step of attaching further includes the steps of:
inserting a first headband tab between a first slot and a second slot on said transparent sheet;
inserting a second headband tab between a third slot and a fourth slot on said transparent sheet;
engaging a first headband notch with said first and second slot; and,
engaging a second headband notch with said third and fourth slots;

attaching a compression strap to said transparent sheet of material; and,
attaching the compression strap to an exterior surface of a helmet.

17. The method of claim 16 , wherein said step of attaching a compression strap further comprises the steps of:
threading a first end of said compression strap through a first plurality of slots located on said transparent material; and,
threading a second end of said compression strap through a second plurality of slots located at a second location on said transparent material.

18. The method of claim 16 , wherein said step of attaching a compression strap further comprises the steps of:
threading a first end of a first compression strap through a first plurality of slots located at a first location on said transparent material; and,
threading a first end of a second compression strap through a second plurality of slots located at a second location on said transparent material.

19. The method of claim 16 , wherein the step of attaching the compression strap to the exterior surface of the helmet comprises the step of placing said compression strap around the exterior surface of the helmet.

20. The method of claim 16 , wherein the helmet is selected from a group of helmets consisting of: military helmets, hard hats, speed boat helmets, climbing helmets, spelunking helmets, watercraft helmets, firefighting helmets, helicopter helmets, and hearing protection helmets.

21. A face shield comprising:
a transparent face covering comprising:
a first plurality of compression strap slots located proximate a top edge and a left side outer perimeter;
a second plurality of compression strap slots located proximate said top edge and a right side outer perimeter; and,
a first plurality and a second plurality of headband slots;

a headband adapted to be coupled to an exterior surface of a helmet, the headband comprising
a first end threaded through said first plurality of headband slots;
a second end threaded through said second plurality of headband slots;
a first notch located proximate said first end and connected to at least one of said first headband slots; and,
a second notch located proximate said second end and connected to at least one of said second headband slots; and,

a compression strap threaded through said first and second plurality of compression strap slots.

22. The face shield of claim 21 , wherein said transparent face covering further comprises a curved bottom perimeter.

23. The face shield of claim 21 , wherein said compression strap comprises elastic.

24. The face shield of claim 21 , wherein said compression strap comprises cord.

25. The face shield of claim 21 , wherein said compression strap comprises a shoelace.

26. The face shield of claim 21 , wherein said transparent face covering comprises a transparent plastic.

27. The face shield of claim 26 , wherein said transparent plastic comprises polycarbonate.

28. The face shield of claim 21 , wherein said transparent face covering and said headband comprises polyethylene terephthalate glycol.

29. The face shield of claim 21 , wherein said transparent face covering and said headband are formed by additive manufacturing.

30. The face shield of claim 21 , wherein said transparent face covering and said headband are formed by injection molding.

31. The face shield of claim 21 , wherein said transparent face covering and said headband are formed by laser cutting.

32. The face shield of claim 21 , wherein the helmet is selected from a group of helmets consisting of: military helmets, hard hats, speed boat helmets, climbing helmets, spelunking helmets, watercraft helmets, firefighting helmets, helicopter helmets, and hearing protection helmets.

33. The face shield of claim 21 , wherein the transparent face covering comprises a flexible material.

34. The face shield of claim 21 , further comprising:
an air gap adapted to prevent fogging of the transparent face covering.

35. The face shield of claim 34 , wherein the air gap is adapted to be located between the transparent face covering and the exterior surface of the helmet.

36. The face shield of claim 34 , wherein the air gap is further adapted to prevent fogging of glasses or optical gear worn by a user of the shield.
