STACKING LATCH MECHANISM

The present invention relates to a latch mechanism configured to secure two bodies together by simply placing one body on top of the other and applying moderate downward pressure to the top body. The latch mechanism includes a housing, a latch partially disposed within the housing, a main body and a primary hook configured to secure a second container to the housing. The latch may be is rotatably engaged to the housing and movable between a first position and a second position. In the first position, the primary hook is adjacent the housing and, in a position, wherein it can secure a second container to the housing. In the second position, the primary hook is distal from the housing and, in a position, wherein it cannot secure a second container to the housing. The latch mechanism also includes a latch bias configured to bias the latch toward its first position. The latch mechanism also includes a stopper slidably engaged to the latch and including a locking surface and holding surface. The stopper is movable between an upper position and a lower position. The latch mechanism also includes a stopper bias configured to bias the stopper toward its upper position such that when the latch is in its first position, the locking surface and primary hook create a negative space configured to receive and secure a second container to the housing. When stopper is in its upper position and the latch is its second position, the holding surface is configured to engage a second container and prevent the latch from rotating back to its first position.
