Abstract
A lever is mounted about an oscillation axis for limited oscillation relative to a first component. A linear tension spring latching member is mounted for rotation on that lever about an axis eccentric to the oscillation axis, the latching member being mounted for frictionally retarded rotation. In the joined condition of second and first components, a latching pin projects from the second component in parallel spaced relation to the oscillation axis and the latching member axis. The tension spring latching member includes a latching hook at its distal end for engagement with the latching pin so that in the latched condition in the components, the spring latching member is tensioned between the latching pin and the eccentric axis. The lever is moved against a limit stop in the latched condition; and in that latched condition the eccentric axis is moved past a plane defined by the oscillation axis and the latching pin, an over center position, so that the latching member tension maintains the lever in that latch condition which becomes a locked condition. The lever is mounted for frictionally retarded rotation on the first component. Simple swinging or oscillation of the lever from …
