Total Claims: 15
Claim 1
Independent Claim
148 words
In a cabinet for portable electronic equipment having a recessed compartment within one of the walls thereof, and a hinged cover movable to an open position and to a closed position mounted over said recessed compartment to provide access thereto, a handle and cover release mechanism comprising; a carrying handle member movable to an extended carrying position and to a retracted storage position attached to a wall of the cabinet, cover retaining means movable into engagement with said cover to retain said cover in the closed position, and actuating means attached to said handle member and engageable with said cover retaining means to move said cover retaining means out of engagement with said cover to release the latter upon operation of said actuating means only when said handle member is in said retracted position, thereby preventing release of said cover when said handle is in said extended position.
Claim 2
Dependent Claim
148 words
In a cabinet for portable electronic equipment having a recessed compartment within one of the walls thereof, and a hinged cover movable to an open position and to a closed position mounted over said recessed compartment to provide access thereto, a handle and cover release mechanism comprising; a carrying handle member movable to an extended carrying position and to a retracted storage position attached to a wall of the cabinet, cover retaining means movable into engagement with said cover to retain said cover in the closed position, and actuating means attached to said handle member and engageable with said cover retaining means to move said cover retaining means out of engagement with said cover to release the latter upon operation of said actuating means only when said handle member is in said retracted position, thereby preventing release of said cover when said handle is in said extended position.
Claim 3
Dependent Claim
25 words
A handle and cover release mechanism as recited in claim 1 wherein said handle member is attached to the wall having the recessed compartment therein.
Claim 4
Dependent Claim
60 words
A handle and cover release mechanism as recited in claim 1 wherein said actuating means includes a pushbutton member mounted in said handle member for movement from a first normal position to a second depressed position, said pushbutton having an end accessible from a surface of said handle member and another end movable into engagement with said cover retaining means.
Claim 5
Dependent Claim
29 words
A handle and cover release mechanism as recited in claim 3 wherein said actuating means includes resilient biasing means for biasing said pushbutton member to said first normal position.
Claim 6
Dependent Claim
