Abstract

A protective cover for a camera having a lens and an image viewer, the protective cover comprises a molded elasticized housing forming a chamber having a body shaped portion and a lens shaped portion for receiving the camera and lens respectively. The housing has at least one opening with a peripheral edge. A fastening system is provided for the opening. The fastening system has an internal fastener attachable to a part of the camera and an external fastener attachable to the internal fastener. The internal fastener and external fastener capture therebetween the peripheral edge of the lens opening when secured to each other, and the external fastener is being movable from a rest view position to to an alternate view position to view a wider area of the camera or lens.

1 . A protective cover for a camera having a lens and an image viewer, the protective cover comprising:
 a molded elasticized housing forming a chamber having a body shaped portion and a lens shaped portion for receiving the camera and lens respectively, the housing having at least one opening with a peripheral edge;   a fastening system for the opening, the fastening system having an internal fastener attachable to a part of the camera and an external fastener attachable to the internal fastener, the internal fastener and external fastener capturing therebetween the peripheral edge of the lens opening when secured to each other, the external fastener being movable from a rest view position to an alternate view position to view a wider area of the camera or lens.   
     
     
         2 . A protective cover as claimed in  claim 1  wherein the external fastener is movable between a rest view position and a alternate view position such that the external fastener can be moved back to the rest view position from the alternate view position when released by the user. 
     
     
         3 . A protective cover as claimed in  claim 1  wherein the external fastener is attached to the internal fastener by a threaded connection. 
     
     
         4 . A protective cover as claimed in  claim 1  wherein the external fastener is attached to the internal fastener by a snap on connection. 
     
     
         5 . A protective cover as claimed in  claim 1  wherein the external fastener comprises a relatively large diameter ring portion and a window sealingly mounted in the ring portion. 
     
     
         6 . A protective cover as claimed in  claim 1  wherein the external fastener comprises a dome shaped window. 
     
     
         7 . A protective cover for a camera as claimed in  claim 6  wherein the internal fastener comprises a dome support for supporting and attaching to the external fastener having the dome shaped window, the dome support and external fastener capturing therebetween the peripheral edge at the lens opening. 
     
     
         8 . A protective cover for a camera having a lens and a flash, the protective cover comprising:
 a molded elasticized housing forming a chamber having a body shaped portion for receiving the camera, the lens and the flash respectively, the housing having at least one opening through which light generated by the flash is transmitted, the opening having a peripheral edge;   a fastening system for the opening, the fastening system having a glove for mounting on the flash, an internal fastener attachable to the glove, and an external fastener attachable to the internal fastener, the internal fastener and external fastener capturing therebetween the peripheral edge of the opening when secured to each other.   
     
     
         9 . A protective cover as claimed in  claim 8  wherein the glove comprises a first end which engages the flash and a second end opposite from the first end which attaches to the internal fastener. 
     
     
         10 . A protective cover for a camera as claimed in  claim 1  wherein the fastening system has an internal fastener with an inlet aperture and an external fastener with an outlet aperture and attachable to the internal fastener, the internal fastener and external fastener capturing therebetween the peripheral edge of the opening when secured to each other, the fastening system further comprising a resilient plug having a channel therethrough and located between the internal fastener and external fastener, the plug having a channel therethrough and being squeezed between the internal fastener and external fastener to form a sealed attachment, the inlet aperture, the channel and the outlet aperture providing a conduit for a cable extending from outside of the cover to the inside thereof, the resilient plug forming a seal with the cable. 
     
     
         11 . A protective cover as claimed in  claim 10  wherein the plug has a frusto-conical shaped portion, which is engaged by a substantially similarly shaped portion on either the external fastener or the internal fastener. 
     
     
         12 . A protective cover as claimed in  claim 11  wherein the plug comprises a slot extending from the channel thereof to the outer surface thereof, the slot facilitating insertion of a cable in the channel of the plug. 
     
     
         13 . A protective cover for a camera having a lens and a tripod attachment, the protective cover comprising:
 a molded elasticized housing forming a chamber having a body shaped portion and a lens shaped portion for receiving the camera and lens respectively, the housing having an opening with a peripheral edge at the tripod attachment;   a fastening system for the opening, the fastening system having an internal fastener attachable to the tripod attachment and an external fastener attachable to the internal fastener, the internal fastener and external fastener capturing therebetween the peripheral edge of the opening when secured to each other.
