Abstract
A lever-lock release system is configured to releasably couple two objects together, for example a parachute and a payload. The lever-lock release system may comprise a first lever and a second lever, each rotatably coupled to a rigid base. When activated, the levers cascadingly rotate to release a first object and a second object. With these systems and related methods, various failure modes may be eliminated, such as undesired premature deployment of recovery parachutes during aerial delivery.
Claims10
A lever-lock release system, comprising:
- a rigid base;
- a first lever coupled to the rigid base such that the first lever is rotatable with respect to the base;
- a second lever coupled to the rigid base such that the second lever is rotatable with respect to the base;
- and
- a third lever coupled to the rigid base such that the third lever is rotatable with respect to the base,
- wherein the first lever comprises a first hook and a first aperture,
- wherein the second lever comprises second hook and a second aperture,
- wherein the third lever comprises a third aperture,
- wherein, when the first lever is in a first rotational position with respect to the base, the first hook extends at least partially through the second aperture to retain the second lever in a fixed position, and
- when the second lever is in a first rotational position with respect to the base, the second hook extends at least partially through the third aperture to retain the third lever in a fixed position.

A lever-lock release system, comprising:
- a rigid base;
- a first lever coupled to the rigid base such that the first lever is rotatable with respect to the base;
- and
- a second lever coupled to the rigid base such that the second lever is rotatable with respect to the base,
- wherein the first lever comprises a first hook and a first aperture,
- wherein the second lever comprises a second aperture, and
- wherein, when the first lever is in a first rotational position with respect to the base, the first hook extends at least partially through the second aperture to retain the second lever in a fixed position,
- wherein the first lever is configured with a cam structure, and
- wherein, when the first lever is rotated, the cam structure comes into contact with the second lever to exert a rotational force on the second lever in the same direction of rotation as the rotation of the first lever.
