Abstract
Abstract A carrying case having two spaced latches recessed in a frame member. The operating member of the latch is disposed in a recess where it will not accidentally be operated, but it can easily be operated by inserting a finger in the recess. The upper surface of the latch mechanism is on a plane substantially the same as the plane of the surrounding case surface when the case is in its locked condition.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A frame and latch structure for a carrying case having two sections pivotally connected to one another along one edge, said structure comprising a longitudinal frame member having a slot therein, and a latch assembly including a bar having ends secured to said frame member at opposite ends of said slot and being offset inwardly equally at each end to form a rectangularly shaped recess with said frame member, a pivoted locking part disposed in said recess and seating in said recess when in its locked position, a longitudinally movable barlike member disposed in one end of said locking part and spaced from the adjacent end of said recess for releasing said locking part, and a spring means for unlocking said section.
Claim 2
Dependent Claim
122 words
A frame and latch structure for a carrying case having two sections pivotally connected to one another along one edge, said structure comprising a longitudinal frame member having a slot therein, and a latch assembly including a bar having ends secured to said frame member at opposite ends of said slot and being offset inwardly equally at each end to form a rectangularly shaped recess with said frame member, a pivoted locking part disposed in said recess and seating in said recess when in its locked position, a longitudinally movable barlike member disposed in one end of said locking part and spaced from the adjacent end of said recess for releasing said locking part, and a spring means for unlocking said section.
Claim 3
Dependent Claim
35 words
