Abstract
Abstract A door latching mechanism includes a rigid hook element mounted upon one component of an enclosure and cooperating with a spring latch member of substantially C-shaped configuration mounted upon another component of the enclosure. A lock bar is provided of improved construction adapted to receive and retain the spring latch member without the use of separate fastening elements.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
175 words
A latching mechanism for retaining a movable component in a closed position with respect to a stationary component, including, hook means attached to one of said components and provided with catch means thereon, latch means carried by the other of said components and provided with a displaceable terminal portion, said hook and latch means disposed in a common horizontal plane whereby upon closure of said movable component said hook means engages and deflects said latch means until said terminal portion passes into said catch means, said latch means comprising a unitary spring metal latch having both upper and lower terminal portions, a vertically displaceable lock bar carried by said movable component, said lock bar having a transverse cut-out providing a vertically extending channel therein having upper and lower limits, and said latch is disposed within said lock bar channel under tension with said latch terminal portions normally abutting said channel limits, whereby said lock bar is operable to vertically displace one said terminal portion from within said catch meAns to permit separation of said components.
Claim 2
Dependent Claim
