20100026015Appliance Access Door Strike Assemblies For Addressing Latch Operation Issues Arising From Dimensional Variances - A technique and various door/latch structures are provided to deal efficiently and effectively with excessive appliance door closure/opening forces that can arise in the case that the door strike extension depth is not ideally matched to the relative location of the mating latch mechanism. This is particularly useful in connection with the use of a push-push style access door that must be compressed against a compressible seal gasket in order to effect both opening and closing of the door. A strike member is mounted to one of an appliance cabinet and door so as to be engagable with a latch mechanism when the door is in the closed position. The installing involves initially tentatively mounting the strike in a first of at least two provisioned ways, to thereby provide a first of at least two different strike extension depths. The door operation is then tested to determine whether an excessive operation force is required in order to open or close the door. Upon determining that an excessive operation force is required to open or close the door, the strike member is removed from its initial mount and remounted in a second of the at least two provisioned ways, to thereby provide a second of the at least two different strike extension depths. In another aspect, a limited amount of z-axis play of the strike is permitted to avoid inadvertent unlatching, e.g., of a push-push latch, upon a slam of the door shut.02-04-2010
