Cabinet lock

A cabinet lock for a cabinet having relatively movable first and second cabinet doors, the cabinet lock comprising

• a frame including a ratchet arm and a first handgrip mount adapted to be mated with a first handgrip included in the cabinet and coupled to the first cabinet door, the ratchet arm including a series of ratchet teeth located between the first end and an opposite second end of the ratchet arm,
• a movable frame retainer including a second handgrip mount arranged to slide back and forth along a travel line on a length of the ratchet arm between the first and second ends and to pivot about a pivot axis that is perpendicular to the travel line to be mated with a second handgrip included in the cabinet, the second handgrip mount being formed to include a handgrip-receiving channel sized to receive a portion of the second handgrip included in the cabinet when the second handgrip mount is mated with the second handgrip, and
• detent means coupled to the second handgrip mount for engaging at least one ratchet tooth on the ratchet arm while the first handgrip mount is coupled to the first handgrip coupled to the first cabinet door following sliding movement of the second handgrip mount along the travel line in a direction from the second end toward the first end to locate a portion of the second handgrip in the handgrip-receiving channel formed in the second handgrip mount after the second handgrip mount has pivoted about the pivot axis to assume a second-handgrip-mating orientation wherein the handgrip-receiving channel formed in the second handgrip mount is arranged to open toward the second handgrip coupled to the second cabinet door so that movement of the second handgrip mount away from the first handgrip mount is blocked while the first handgrip mount is mated to the first handgrip coupled to the first cabinet door when the first and second cabinet doors are in a closed position to block relative movement of the first and second cabinet doors to opened positions,
• wherein the ratchet arm includes a first guide slot arranged to extend along the travel line and the movable frame retainer further includes a first guide pin coupled to the second handgrip mount and arranged to extend into and travel back and forth in the first guide slot along the travel line to support the second handgrip mount for sliding and pivoting movement relative to the ratchet arm during coupling of the movable frame retainer to the second handgrip and uncoupling of the movable frame retainer from the second handgrip,
• wherein the second handgrip mount includes a top segment having a free end and an opposite proximal end, a bottom segment having a free end and an opposite proximal end, and a bight segment arranged to interconnect the proximal ends of the top and bottom segments and cooperate with the top and bottom segments to define the handgrip-receiving channel, the first guide pin is coupled to the free end of the top segment, and the detent means is coupled to the top segment and arranged to lie between the first guide pin and the proximal end of the top segment, wherein the top, bight, and bottom segments cooperate to provide the second handgrip mount with a C-shape,
• wherein the first handgrip mount has a closed-loop shape and is formed to include opening means for receiving a portion of the first handgrip therein to support the frame for rotation about the first handgrip to cause the frame to stay attached to the first handgrip during rotation of the frame about the handgrip to place the ratchet arm on an upward-facing portion of the second handgrip before the second handgrip mount is pivoted about the pivot axis to assume the second-handgrip-mating orientation so that the second handgrip mount can be moved along the travel line on the ratchet arm toward the first handgrip mount to cause the detent means to engage the at least one ratchet tooth.
