US Patent 11852186 Dial cam latch

An apparatus provides a latch with a rotary dial and a leaf spring with teeth that extend from a frame into an engaging position. Inward axial movement of the dial causes the dial to deform the leaf spring and the teeth to extend into the engaging position. In the engaging position, the dial supports the teeth and resists forces that might otherwise cause the teeth to unlatch. In the engaging position, a catch in a track on the dial engages a pin of the frame to maintain the engaging position. From the engaging position, a rotation of the dial unseats the catch and allows the dial to move axially outward and the teeth to recede into the frame.
