Spectacle frame mount for face mask
View Patent ↗A spectacle frame mount provides secure, removable positioning of a spectacle frame in a gas mask or full face respirator. A spring wire mount supports the spectacle frame between two legs of a loop. The spring wire mount includes two leg portions that have lower ends which terminate adjacent each other when the mount is in its use position. The two leg portions positively engage an internal portion of the full face mask so that the spectacle frame will be positioned within the interior of the mask at a location such that the spectacles will be properly positioned for use by the person wearing the mask.
1. A spectacle frame mount usable to position a spectacle frame in a face mask comprising:
a spring wire having a first end and a second end;
a loop in the spring wire intermediate the first and second ends, the loop being positioned in the spring wire generally equidistant the first and second ends and dividing the spring wire into first and second spring wire portions;
an upper section and a lower section in each of the first and second spring wire portions; and
a bend in each spring wire portion between the upper section and the lower section of each spring wire portion, the first and second ends of the spring wire being positioned adjacent each other.
2. The spectacle frame mount of claim 1 wherein the loop includes first and second loop sides connected by a loop transverse bar.
3. The spectacle frame mount of claim 2 wherein the loop is upwardly opening.
4. The spectacle frame mount of claim 3 wherein the first and second spring wire ends are generally horizontal and overlapping.
5. The spectacle frame mount of claim 4 further including a termination device, and wherein the overlapping spring wire ends are both slidably positioned in the termination device.
6. The spectacle frame mount of claim 5 wherein the termination device is a coil spring.
7. The spectacle frame mount of claim 6 further including a protective sheath overlying the coil spring.
8. The spectacle frame mount of claim 7 wherein the protective sheath is a heat shrinkable plastic.
9. The spectacle frame mount of claim 6 wherein the coil spring has coil ends adapted to reduce an effective diameter of the coil spring.
10. The spectacle frame mount of claim 5 wherein the termination device is a resilient sleeve.
11. The spectacle frame mount of claim 4 wherein the first and second spring wire ends are engageable with a wraparound lens of the face mask adjacent a base portion of the face mask.
12. The spectacle frame mount of claim 2 wherein the loop is downwardly opening.
13. The spectacle frame mount of claim 12 wherein the upper sections of the first and second portions of the spring wire are generally parallel.
14. The spectacle frame mount of claim 13 wherein the lower sections of the first and second portions of the spring wire form a circular base mount.
15. The spectacle frame mount of claim 14 wherein the first and second ends of the spring wire are adjacent each other.
16. The spectacle frame mount of claim 14 further including friction enhancing covers on the first and second ends of the spring wire.
17. The spectacle frame mount of claim 14 wherein the circular base mount is sized to retentively engage a base portion of the face mask.
18. The spectacle frame mount of claim 1 wherein the lower sections of the first and second spring wire positions are arcuate.
19. The spectacle frame mount of claim 1 wherein the bend in each of the spring wire positions is generally 90°.
20. The spectacle frame mount of claim 1 wherein a distance between the first and second ends of the spring wire is variable in response to the application of a force to the upper sections of the first and second spring wire portions.
