Abstract

Previous types of armored safety workwear are too inflexible, heavy or expensive to be useful. The present invention provides an article of protective clothing comprising a flexible supporting material and a plurality of elongated coil springs held in close proximity to the surface of said supporting material at spaced locations. Preferably, the coil springs are free to rotate in relation to the supporting material. The coil springs are held in elongated pockets secured to the surface of said supporting material.

Claims

1. An article of protective clothing comprising a flexible supporting material and a plurality of elongated coil springs held in close proximity to the surface of said supporting material in elongated pockets formed adjacent to the surface of said supporting material at spaced locations wherein said coil springs are free to rotate within said pockets in relation to said supporting material.

2. The article of protective clothing of claim 1 wherein said pockets each comprise a layer of flexible material secured to said supporting material.

3. The article of protective clothing of claim 1 wherein said supporting material forms a glove.

4. The article of protective clothing of claim 1 wherein said supporting material forms a mitt.

5. The article of protective clothing of claim 1 wherein said supporting material forms an apron.

6. The article of protective clothing of claim 1 wherein said supporting material forms a sleeve.

7. The article of protective clothing of claim 1 wherein said supporting material forms a suit.

8. The article of protective clothing of claim 1 wherein said supporting material forms a boot.

9. The article of protective clothing of claim 1 wherein said supporting material forms a spat.

10. The article of protective clothing of claim 1 wherein said supporting material hangs downwardly from a hat to substantially cover the side and back of the wearer'"'"'s neck.

11. The article of protective clothing of claim 1 wherein each said elongated pocket has an open end and means to releasably close said open end.

12. The article of protective clothing of claim 1 wherein said coil springs comprise an inner coil spring and an outer coil spring, said inner coil spring having an outer diameter less than the inner diameter of said outer coil spring.

13. The article of protective clothing of claim 12 wherein said inner coil spring is free to rotate relative to said outer coil spring.

14. The article of protective clothing of claim 12 wherein said inner and outer coil springs are closed-coil springs.

15. The article of protective clothing of claim 13 wherein said inner coil spring is freely separable from said outer coil spring.

16. The article of protective clothing of claim 12 wherein the direction of slope of the coils of said inner coil spring is opposite to the direction of slope of the coils of said outer coil spring.

17. The article of protective clothing of claim 12 wherein the length of said inner coil spring is less than or approximately equal to the length of said outer coil spring.

18. The article of protective clothing of claim 2 in which said flexible pocket material is more readily cut or torn than said supporting material.

19. The article of protective clothing of claim 2 wherein each said pocket is formed of a separate piece of flexible material.

20. The article of protective clothing of claim 2 wherein said pockets are secured to said supporting material by stitching.

21. The article of protective clothing of claim 20 wherein said stitching is readily broken when contacted by the operative cutting edge of a power tool.

22. The article of protective clothing of claim 11 wherein said means for releasably closing said open end comprises a flap having one end secured to said article and one end releasably secured to said article, and means for releasably securing said releasable end.

23. The article of protective clothing of claim 22 wherein said means for releasably securing said releasable end of said flap comprises a hook and loop fastener.

24. The article of protective clothing of claim 1 wherein said coil springs are each freely removable from said pockets.

25. The article of protective clothing of claim 12 wherein said coil springs are each freely removable from said pockets.

26. The article of protective clothing of claim 1 wherein said coil springs are each free of any connection to said pockets.

27. The article of protective clothing of claim 13 wherein said coil springs are each free of any connection to said pockets.
