Abstract: The present invention provides a triggering mechanism that utilizes stepped triggering of successively higher-pre-loaded, counterdirected, nested stages. The present invention thus presents a triggering mechanism whereby an input force of a first value can result in an actuation force of a second value. In the preferred embodiment, the second force is greater than the first force. The present invention is suitable for incorporation in any apparatus taking advantage of its ability to use an input force of a given magnitude and provide an actuation force of different magnitude. Such devices include, but are not limited to, those utilizing hydrostatic pressure for actuation of flotation, marking, and retrieval devices, devices actuated by barostatic, mechanical, and pneumatic pressure, and devices that trigger chemical (including pyrotechnic), electrical, mechanical, and pneumatic devices. There is theoretically no limit to the number of successive stages in the triggering mechanism of the present invention.

Abstract: The present invention utilizes low-friction, stepped triggering of successively higher-pre-loaded, counterdirected, nested stages in a compact configuration to efficiently multiply an input force. The present invention thus presents a novel force-multiplying mechanism for incorporation in any apparatus taking advantage of its ability to convert a force of a given magnitude into a force of greater magnitude. Such devices include, but are not limited to, those utilizing hydrostatic pressure for actuation of flotation, marking, and retrieval devices, those actuated by barostatic, mechanical, and pneumatic pressure, and those which trigger chemical (including pyrotechnic), electrical, mechanical, and pneumatic devices. There is theoretically no limit to the force multiplication inherent in the design, given the option of successive stages and ever-increasing driving forces.
