Total Claims: 9
Claim 1
Independent Claim
328 words
A door latching structure for a furniture case or the like having a door movable to a closed position comprising a keeper member mounted on said case and a latch member mounted on said door for engagement with said keeper member when said door is in closed position, said keeper member including a unitary plastic piece of generally plate-like, rectangular configuration providing four sides and a pair of faces, one of said faces being substantially flat and positioned in confronting relation with said case, the oTher of said faces being equipped with an integral ridge-shaped projection extending parallel to and adjacent to one of said sides to provide means for engagement with said latch member, a pair of elongated slots in said keeper member extending from one face to the other with the slot length extending generally perpendicularly to said one side, screw means extending through said slots for securing said keeper member to said case, said latch member also including a unitary plastic piece of generally plate-like rectangular configuration providing thereby four sides and a pair of faces, one of said faces being substantially flat and positioned in confronting relation with said door, the other of said faces being equipped with an integral arm adjacent one of the sides of said piece to provide means for engagement with said keeper member, a pair of elongated slots in said latch member extending from one face to the other with the slot length extending generally perpendicular to the said one side of said latch member, and screw means extending through said slots for securing said latch member to said door, said arm adjacent the extremity thereof having an integral ridgeshaped projection outstanding therefrom on the arm side adjacent said latch member one side, said arm being relatively resilient to permit flexing thereof and past said arm projection past said keeper member projection, said arm being equipped with rib means on the side thereof opposite the first mentioned arm side.

Claim 3
Dependent Claim
18 words
The structure of claim 1 in which said rib means are tapered in proceeding outwardly of said arm.
Claim 4
Dependent Claim
17 words
The structure of claim 2 in which a pair of spaced-apart ribs are provided on said arm.

23 words
The structure of claim 1 in which the length of said keeper member projection is at least twice the width of said arm.
Claim 9
Dependent Claim
17 words
The structure of claim 7 in which the ridge length is approximately three times the arm width.
