Abstract
A sealable enclosure for wafers has a door with an easily accessible and disassembleable latching mechanism which utilizes a minimal number of moving parts. The door includes an enclosure with a cammed member rotatable on a post and in engagement with a pair of latching arms that extend, retract, move upwardly and downwardly or forwardly and rearwardly depending on whether the door is a front side door or a bottom door. The movement of the latching arms is accomplished by cammed portion of the cammed member configured to move cam follower portions of the latching arms in an axial direction with respect to the cammed member and in a radial direction. The latching arm pivots on a fulcrum within the enclosure. The latching mechanism is accessible through a panel that attaches by integral detents on the panel that cooperate with recesses on the interior edge walls of the door enclosure. The rotatable member has a slotted center and is secured on a T-shaped post extending from the enclosure by placement on the post in an insertion rotational position. When assembled the rotation of the cammed member is restricted to the operative range by stops on the enclosure.
