EYEPIECE ATTACHMENT FOR RESPIRATORS |
摘要 |
A sight-corrective lens is attached between an eyepiece of a respirator and the eye of the wearer by a monocular mount into which the lens fits as if into a standard spectacle frame. Attachment devices for the mount are apertured lugs on a surround of the eyepiece and tabs on the mount. By making the tab and mount in one position of different tangential width from the tab and mount in the other, a desired unique positioning of the lens is assured. The mount may have a seal ring of which the deformable ridge is pretensioned against the eyepiece by the fitting of the tabs in the lugs to prevent ingress of moisture or particles between them. |
