Abstract
The mechanical lock includes a rod having one end extending into a housing and another end extending out of the housing. The rod translate through bores through bushings within the housing. Coil springs in the housing and surround the rod. When the springs are in their normal orientation, they grip the rod tightly and prevent the rod from translating. The rod and bushings have complementary structure for preventing the rod from rotating within the bushings and housing. In the exemplary embodiment, the structure are flat surfaces along the rod and the bushing that mate with each other.
