ABSTRACT:
A protective covering device for telescopic optical instruments that are being used in the field, comprises a single expanse of flexible waterproof material (4) having sufficient size to envelope the lenses and lense housing tubes on a telescopic instrument (20). Attached to the fabric (4) edge is a length of elastic (6) member running along the entire perimeter, except for the length of a skirt (12) whereby the elastic member divides the skirt from the rest of the cover (18). Attached to the elastic edge directly across from the skirt are two loops (14) provided for holding attachment straps (10A and 10B). The attachment straps are elastic with a coating of silicone rubber (16) on one side and means for releasably connecting the strap ends together are provided by hook and loop material (8), whereby the straps can be pulled around circumferentially and hooked to the objective end of optical instrument.
As the covering device (18) is pulled up and over the instrument by the skirt, the integral elastic member is stretched into tension, providing a retaining and sealing of the flexible material about the lenses and body of the optical instrument.
