Optical casing with skylight arrangement

Abstract

An optical casing for spectacles includes a case body defining a receiving cavity, and a skylight arrangement. The skylight arrangement contains a top skylight opening formed on a top ceiling of the case body, and includes a skylight panel, having a cross sectional shape corresponding with a shape of the skylight opening, movably mounted on the case body to slide between an opened position and a closed position, wherein in the opened position, the skylight panel is selectively slid along the skylight opening for exposing the receiving cavity to an exterior of the case body so as to allow visual and physical access of the spectacles via the skylight opening, wherein in the closed position, the skylight panel is slid along the skylight opening to close the skylight opening for blocking physical and visual access between the receiving cavity and an exterior of the case body.

       6 . The optical casing, as recited in  claim 3 , wherein said skylight panel has a curved and downwardly inclined cross sectional shape from a rear edge to a front edge thereof while said top ceiling of said case body also has a correspondingly curved and inclined cross sectional shape so that a top surface of said skylight panel is fittedly aligned with said top ceiling of said case body, so that said skylight arrangement fits optimally with said case body for completely closing said receiving cavity when said skylight panel is in said closed position. 
   
   
       7 . The optical casing, as recited in  claim 1 , wherein said skylight arrangement further has a stopper track transversely extended between said two side sliding tracks and formed as a bottom rim portion of said skylight opening for stopping a downward sliding movement of said skylight panel at said front edge thereof. 
   
   
       8 . The optical casing, as recited in  claim 4 , wherein said skylight arrangement further has a stopper track transversely extended between said two side sliding tracks and formed as a bottom rim portion of said skylight opening for stopping a downward sliding movement of said skylight panel at said front edge thereof. 
   
   
       9 . The optical casing, as recited in  claim 5 , wherein said skylight arrangement further has a stopper track transversely extended between said two side sliding tracks and formed as a bottom rim portion of said skylight opening for stopping a downward sliding movement of said skylight panel at said front edge thereof. 
   
   
       10 . The optical casing, as recited in  claim 6 , wherein said skylight arrangement further has a stopper track transversely extended between said two side sliding tracks and formed as a bottom rim portion of said skylight opening for stopping a downward sliding movement of said skylight panel at said front edge thereof. 
   
   
       11 . The optical casing, as recited in  claim 7 , wherein said stopper track defines an L-shaped stopper groove formed at a bottom rim of said top skylight opening wherein said corresponding front edge of said skylight panel is arranged to slidably engage with said stopper groove when said skylight panel is at said closed position. 
   
   
       12 . The optical casing, as recited in  claim 8 , wherein said stopper track defines an L-shaped stopper groove formed at a bottom rim of said top skylight opening wherein said corresponding front edge of said skylight panel is arranged to slidably engage with said stopper groove when said skylight panel is at said closed position. 
   
   
       13 . The optical casing, as recited in  claim 9 , wherein said stopper track defines an L-shaped stopper groove formed at a bottom rim of said top skylight opening wherein said corresponding front edge of said skylight panel is arranged to slidably engage with said stopper groove when said skylight panel is at said closed position.
