Abstract (en)
A magnetic latch assembly includes a latch member (18, 82, 118) movably mounted to a first object (10, 68, 108) such as a door and a container, and a retainer (34, 94, 132) arranged in a second, opposing object (12, 70) such as a door frame and a lid. The latch member (18, 82, 118) includes a latch arm (20, 84, 124), a hook (24, 86, 126) formed on the distal end of the latch arm (20, 84, 124), and a first magnet (26, 92, 130) mounted in the hook (24. 86, 126). The retainer (34, 50, 94, 132) includes a housing (36, 52, 94, 134) with a cavity (40, 54, 96, 138) and a second magnet (42, 64, 100, 142). The cavity (40, 54, 96, 138) includes a first horizontal passage (40a, 54a, 96a, 138a) and a second vertical passage (40b. 54b, 96b, 138b) communicated with the horizontal passage (40a, 54a, 96a, 138a). The second magnet (42, 64, 100, 142) has a magnetic pole of opposite polarity from the magnetic pole of the first magnet (26, 26, 92, 130). When the first and second objects are relatively moved toward each other, the latch member (18, 82, 118) is moved into the first passage (40a, 54a, 96a, 138a) of the cavity (40, 54, 96, 138). When the latch head (24, 86, 126) is completely received in the first passage (40a, 54a, 96a, 138a), the two magnets (26, 42, 64. 92. 100, 130, 142) are operatively associated to cause the latch member (18, 82, 118) to be moved from the horizontal passage (40a, 54a, 96a, 138a) to the vertical passage (40b, 54b, 96b, 138b) and urge the latch member (18, 82, 118) or the latch head (24, 86, 126) into latching engagement with one end of the housing (36, 52, 94, 134) which serves as a retainer.
