Title:
EYE SIGHT CORRECTION LENS MOUNTING MEANS AND RESPIRATION MASK THEREWITH
Document Type and Number:
Japanese Patent JPS61145523
Kind Code:
A
Abstract:
A sight-corrective lens (19) is attached between an eyepiece (3) of a respirator and the eye of the wearer by a monocu- lar mount (10) into which the lens fits as if into a standard spectacle frame. Attachment means for the mount are apertured lugs (6, 7) on a surround (2) of the eyepiece and tabs (13, 14) 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 (20) of which the deformable ridge (21) is pretensioned against the eyepiece by the fitting of the tabs in the lugs to prevent ingress of moisture or particles between them.
