Abstract

In one aspect, a protective headwear is provided and includes a headgear, an outer shell rotatably coupled to the headgear, and a first shield coupled to the outer shell and rotatable between a first position and a second position. The first shield is selectively removable from the outer shell without the use of tools. The protective headwear also includes a second shield coupled to the outer shell. The first shield covers the second shield to a greater extent in the first position than in the second position. In one aspect, a method of manufacturing a protective headwear is provided.

First claim

The invention claimed is:

1. A protective headwear comprising:
an outer shell including a front, a right side, a left side opposite the right side, a top and a bottom opposite the top;
a first shield coupled to the outer shell and rotatable between a first position and a second position, wherein the first shield is selectively removable from the outer shell;
a second shield coupled to the outer shell, wherein the first shield covers the second shield to a greater extent in the first position than in the second position, and wherein the first shield is positioned over the top of the outer shell in the second position; and
a first actuator including a shell portion coupled to the outer shell and a shield portion coupled to the first shield, wherein the shell portion and the shield portion are selectively engageable to couple the first shield to the outer shell, and wherein the first actuator is configured to be actuated to a first actuator position to allow removal of the first shield from the outer shell, and wherein, with the first shield removed from the outer shell, the shell portion remains coupled to the outer shell and the shield portion remains coupled to the first shield; and
a second actuator, wherein the second actuator is configured to be actuated to a second actuator position to facilitate rotation of the first shield relative to the outer shell.

2. The protective headwear of claim 1 , wherein the first shield completely covers the second shield in the first position and wherein the first shield exposes at least a portion of the second shield in the second position.

3. The protective headwear of claim 1 , wherein the first shield has a first viewing capacity and the second shield has a second viewing capacity greater than the first viewing capacity.

4. The protective headwear of claim 1 , wherein the outer shell includes a rear opposite the front, wherein the first shield is coupled to the front of the outer shell and is removed from the outer shell by moving the first shield in a direction out from the front of the outer shell along an axis extending from the rear toward the front of the outer shell.

5. The protective headwear of claim 1 , wherein the first shield rotates relative to the outer shell about a first axis, and wherein the first shield is removed from the outer shell along a second axis transverse to the first axis.

6. The protective headwear of claim 1 , wherein the first shield rotates relative to the outer shell about a first axis, and wherein the first shield is removed from the outer shell along a second axis perpendicular to the first axis.

7. The protective headwear of claim 1 , wherein the first shield does not cover the second shield with the first shield in the second position such that viewing through the second shield is unimpeded.

8. The protective headwear of claim 1 , further comprising a biasing member coupled to the first shield, wherein the biasing member is configured to bias the first shield toward the second position.

9. The protective headwear of claim 8 , wherein the biasing member cooperates with the first shield as an over-center biasing member and is configured to selectively bias the first shield toward either the first position or the second position based on a position of the first shield.

10. The protective headwear of claim 1 , wherein the first shield has an inner surface and an outer surface, wherein the inner surface of the first shield faces the second shield with the first shield in the first position and faces the top of the shell with the first shield in the second position.

11. The protective headwear of claim 1 , wherein the first actuator position comprises the actuator being actuated in a first amount, and the second actuator position comprises the actuator being actuated in a second amount.

12. The protective headwear of claim 1 , wherein the second actuator is configured to be actuated to the second actuator position to allow rotation of the first shield relative to the outer shell.

13. The protective headwear of claim 1 , wherein the first shield is an auto-darkening shield.

14. The protective headwear of claim 1 , further comprising a biasing member coupled to the first shield, wherein the biasing member is configured to bias the first shield towards the second position.

15. A protective headwear comprising:
an outer shell including a front, a right side, a left side opposite the right side, a top and a bottom opposite the top;
a first shield coupled to the outer shell and rotatable between a first position and a second position, wherein the first shield is selectively removable from the outer shell;
a second shield coupled to the outer shell, wherein the first shield covers the second shield to a greater extent in the first position than in the second position, and wherein the first shield is positioned over the top of the outer shell in the second position; and
a first actuator including a shell portion coupled to the outer shell and a shield portion coupled to the first shield, wherein the shell portion and the shield portion are selectively engageable to couple the first shield to the outer shell, and wherein the actuator is configured to be actuated to a first actuator position to allow removal of the first shield from the outer shell, and wherein, with the first shield removed from the outer shell, the shell portion remains coupled to the outer shell and the shield portion remains coupled to the first shield; and
a second actuator, wherein the second actuator is configured to be actuated to a second actuator position to facilitate rotation of the first shield relative to the outer shell.

16. The protective headwear of claim 15 , wherein the second actuator is configured to move relative to the first shield when actuated.

17. The protective headwear of claim 15 , wherein the first and second actuator each comprise at least one of a detent type actuator, a spring biased actuator, a projection and recess actuator, a ratchet type actuator, a latch actuator, a latch buckle actuator, or a friction-based actuator.

18. The protective headwear of claim 15 , wherein the second actuator is configured to be actuated to the second actuator position to allow rotation of the first shield relative to the outer shell.

19. The protective headwear of claim 15 , further comprising a biasing member coupled to the first shield, wherein the biasing member is configured to bias the first shield towards the second position.

20. The protective headwear of claim 15 , wherein the first shield is an auto-darkening shield.

21. The protective headwear of claim 15 , further comprising a biasing member coupled to the first shield, wherein the biasing member is configured to bias the first shield towards the second position, wherein the second actuator is configured to move relative to the first shield when actuated.
