Abstract
Abstract A brief case comprises two oppositely disposed side shells which are hinged together at a centrally located valence. Double action locks on the valence individually lock or otherwise secure each of the two side shells in position adjacent the valence. When the lock mechanism is operated in one manner, one side shell is released, and when the lock mechanism is operated in another manner the other side shell is released. A special procedure is required to release both side shells simultaneously. The valence includes a closed, deep tray compartment which may be either permanently or releasably secured therein. The deep tray faces one side shell to cooperate with that side shell and form a completely closed compartment. The bottom of the tray blocks the other side shell from view.

Claim 1
Independent Claim
332 words
A double-action brief case comprising a central valence member, two oppositely disposed five-sided side shells hinged together via said central valence member, the sixth and open side of each of the two side shells coming together on opposite sides of the valence, double-action locking means on the valence for alternatively securing said two side shells individually in closed positions adjacent the valence, and for releasing said side shells as desired, said locking control means operable to release either of said side shells independently of the other and to release both said shells simultaneously with one manual operation; first side shell latching means extending from said first side shell into said locking means and cooperating with said double action locking means to release one side shell from the valence when said locking means is operated, second side shell latching means extending from said second side shell into said locking means and cooperating with said double action locking means to release another side shell from the valence when said locking means is operated, and a deep tray closed compartment secured in the valence, the deep tray facing one side shell to form in cooperation therewith a closed compartment while completely blocking the other side shell from view, said first and second side shell latching means comprising hasps, said hasps having a grooved shape enabling restraint and release by said double action locking means whereby said side shells are merged with said valence when said hasps are restrained and released from said valence when said hasps are released from said double action locking means, and said locking means including four locks, two at each end of said valence, each of said side shells having said hasps on opposite ends, to cooperate with individually associated ones of said locks, said two locks at each end of said valence having directionally opposing lock release means requiring reverse directional movement of each of said locks at each end of said valence respectively to simultaneously release both side shells.
Claim 2

332 words
A double-action brief case comprising a central valence member, two oppositely disposed five-sided side shells hinged together via said central valence member, the sixth and open side of each of the two side shells coming together on opposite sides of the valence, double-action locking means on the valence for alternatively securing said two side shells individually in closed positions adjacent the valence, and for releasing said side shells as desired, said locking control means operable to release either of said side shells independently of the other and to release both said shells simultaneously with one manual operation; first side shell latching means extending from said first side shell into said locking means and cooperating with said double action locking means to release one side shell from the valence when said locking means is operated, second side shell latching means extending from said second side shell into said locking means and cooperating with said double action locking means to release another side shell from the valence when said locking means is operated, and a deep tray closed compartment secured in the valence, the deep tray facing one side shell to form in cooperation therewith a closed compartment while completely blocking the other side shell from view, said first and second side shell latching means comprising hasps, said hasps having a grooved shape enabling restraint and release by said double action locking means whereby said side shells are merged with said valence when said hasps are restrained and released from said valence when said hasps are released from said double action locking means, and said locking means including four locks, two at each end of said valence, each of said side shells having said hasps on opposite ends, to cooperate with individually associated ones of said locks, said two locks at each end of said valence having directionally opposing lock release means requiring reverse directional movement of each of said locks at each end of said valence respectively to simultaneously release both side shells.
Claim 3
Dependent Claim
253 words
A double-action brief case comprising a central valence member, two oppositely disposed five-sided side shells hinged together via said central valence member, the sixth and open side of each of the two side shells coming together on opposite sides of the valence, double-action locking means on the valence for alternatively securing two side shells individually in closed positions adjacent the valence, and for releasing said side shells as desired, said locking control means operable to release either of said side shells independently of the other and to release both said shells simultaneously with one manual operation; first side shell latching means extending from said first side shell into said locking means and cooperating with said double action locking means to release one side shell from the valence when said locking means is operated, second side shell latching means extending from said second side shell into said locking means and cooperating with said double action locking means to release another side shell from the valence when said locking means is operated, and a deep tray closed compartment secured in the valence, the deep tray facing one side shell to form in cooperation therewith a closed compartment while completely blocking the other side shell from view, said locking means including toggle clasp means which cooperate with said first and second side shell latching means towards alternatively releasing said side shells independently of each other as well as simultaneously to each other as a function of the position to which said toggle clasp means is pivoted.
