Abstract

Provided herein are examples of bead worn supports, such as eyewear, configured to provide passive venting by providing pathways between a lens and a frame and/or by providing a smooth anterior profile to allow a laminar flow of air on an anterior surface of the lens. The pathways through the frame and lens of the eyewear can be configured such that they do not provide a direct path to the eye of a wearer. The headworn supports provided hemin can provide venting while reducing or preventing unwanted light, particles, or other debris from contacting the eye of the user. The headworn supports can also be configured to exhibit excellent ballistic performance.

First claim

The following is claimed:

1. A headworn support kit comprising:
a lens comprising;
a first lateral end portion and a second lateral end portion both lateral of a wearer's eyes in an as-worn position;
a horizontal axis extending between the first and second lateral end portions;
a first projection extending, at the first lateral end portion, along the horizontal axis in a first direction;
a second projection extending, at the second lateral end portion, along the horizontal axis in a second direction opposite the first direction;
a medial portion between the first and second lateral end portions of the lens;
an angled projection extending, at the medial portion, diagonally with respect to the horizontal axis and forming a notch that extends diagonally with respect to the horizontal axis into an upper surface of the lens;

a first frame comprising:
a first lens support adapted to receive the lens,
a movable projection to selectively secure the lens relative to the first frame, the movable projection being disposed at and movable relative to a first lateral end portion of the first lens support, the movable projection being lateral of the wearer's eyes in an as-worn position, and
a first passive retention mechanism disposed at a second lateral end portion of the first lens support, the first passive retention mechanism being lateral of the wearer's eyes in an as-worn position and comprising a groove configured to receive the second projection of the lens, wherein the second lateral end portion of the first lens support is configured to support the lens solely with the first passive retention mechanism,
a second passive retention mechanism disposed at a medial portion of the first lens support between the first and second lateral end portions of the first lens support, the second passive retention mechanism comprising a guide slot configured to receive the angled projection and align the first projection of the lens for securement to the first frame by the movable projection, wherein the medial portion of the first lens support is configured to support the lens solely with the second passive retention mechanism; and

a second frame comprising:
a second lens support adapted to support the lens in the wearer's field of view, the second lens support having a channel configured to receive the lens and secure the lens in place,

wherein the lens is interchangeable between the first frame and the second frame such that the lens is configured to be removable from and supported by the first frame and the second frame.

2. The headworn support kit of claim 1 , wherein:
the first frame is an eyeglass frame and the first lens support is an eyeglass lens support, the eyeglass frame comprising an earstem attached to the eyeglass lens support; and
the second frame is a goggle frame, the goggle frame comprising a padded layer attached to a posterior surface of the second lens support, the padded layer configured to be pressed against a head of the wearer when in use.

3. The headworn support kit of claim 1 , wherein the lens comprises a unitary lens.

4. The headworn support kit of claim 3 , wherein the first frame further comprises one or more contact points configured to contact the unitary lens when the lens is secured to the first frame.

5. The headworn support kit of claim 4 , wherein, between two or more contact points, a posterior surface of the first frame extends a protrusion distance rearward beyond a posterior extension of a posterior surface of the lens, the protrusion distance being less than or equal to about 4 millimeters.

6. The headworn support kit of claim 5 , wherein when the lens is secured to the first frame, an upper edge of the lens and a lower edge of the first lens support are spaced apart between two or more contact points to allow venting of the lens.

7. The headworn support kit of claim 6 , wherein a total chord length of the upper edge that is spaced apart from the first frame is at least 20% of a total chord length of the upper edge of the lens.

8. The headworn support kit of claim 4 , wherein, between two or more contact points, a posterior surface of the first frame extends a protrusion distance rearward beyond a posterior extension of a posterior surface of the lens, the protrusion distance being less than or equal to about 3.2 times a center thickness of the lens.

9. The headworn support kit of claim 8 , wherein the protrusion distance is less than or equal to the center thickness of the lens.

10. The headworn support kit of claim 1 , the first frame comprising a posterior surface facing toward the wearer's head in an as-worn position, wherein when the lens is secured to the first frame, at least one gap is formed between the posterior surface of the first frame and an anterior surface of the lens facing away from the wearer's head in an as-worn position, the at least one gap positioned at a region where the posterior surface of the first frame overlaps the anterior surface of the lens.

11. The headworn support kit of claim 1 , wherein a headworn support comprising the lens secured to the first frame or the lens secured to the second frame is configured to withstand a ballistic impact of a 0.25″ diameter steel ball having a speed of at least about 150 feet per second.

12. The headworn support kit of claim 1 , wherein a headworn support comprising the lens secured to the first frame or the lens secured to the second frame is configured to withstand a ballistic impact of a 0.15 caliber, 5.85 grain, cylindrical-shaped, chamfered edge fragment having a speed of at least about 640 feet per second.

13. The headworn support kit of claim 1 , wherein:
the first frame is an eyeglass frame and the first lens support is an eyeglass lens support, the eyeglass frame comprising an earstem attached to the eyeglass lens support; and
the second frame includes a portion of a helmet configured to be worn on the head of the wearer when in use.

14. The headworn support kit of claim 1 , wherein the first lens support has a partial orbital, and wherein the second lens support has a full orbital.

15. The headworn support kit of claim 1 , wherein the first frame is an eyewear frame and the second frame is a helmet frame.

16. The headworn support kit of claim 1 , wherein:
the first frame comprises earstems, the first lens support having a partial orbital; and
the second frame comprises earstems, the second lens support having a full orbital.

17. The headworn support kit of claim 1 , wherein
the movable projection comprises a door to selectively cover the first projection.

18. The headworn support kit of claim 17 , the first frame further comprising an earstem pivotably attached to the first lens support, wherein pivoting the earstem from a folded position to an extended position relative to the first lens support closes the door over the protrusion first projection, thereby locking the lens to the first lens support.

19. The headworn support kit of claim 17 , the first frame further comprising an earstem pivotably attached to the first lens support, wherein the earstem prevents the door from opening when the earstem is in an extended position relative to the first lens support.

20. The headworn support kit of claim 1 , wherein the first frame and the second frame are structurally different.

21. A headworn support kit comprising:
a unitary lens comprising:
a lateral end portion lateral of a wearer's eyes in an as-worn position, and
a projection extending at the lateral end portion;
