Title:
扉および2カ所でばね偏倚した掛止機構
Document Type and Number:
Japanese Patent JP4431393
Kind Code:
B2
Abstract:
A wafer container with a door, the door has at least one latching mechanism, wherein the latching mechanism has a spring member that holds the latching mechanism at one or more desired positions that preferably correspond to latch-open and latch-closed conditions. In a preferred embodiment, the spring member has an over-center condition that urges the latching mechanism towards the favored positions, thereby resisting unintended actuation of the latching mechanism. Moreover, in preferred embodiments, the latching mechanism has soft stops at the latch open or latch closed condition that minimizes abrupt snapping into position of the latching mechanism. Preferred embodiments utilize a rotatable member configured as a cammed member with an elongate rigid plastic member having at least one node, forming a plastic spring. The spring is pivotally mounted on the rotatable member and pivotally mounted to the door structure.
