Abstract
A quick-loosening mechanical linking device that includes housing, a release cavity having a predetermined height, a bolt, and an actuator. The bolt is disposed within the housing and includes an attachment means projecting out from the housing, a release zone such as an intended failure zone, and a head with a piston face. Upon actuation of the actuator, the bolt deforms and/or fails at the release zone and the attachment means moves farther out from the housing by a distance equal to the height of the release cavity. The release cavity preferably includes an abutment formed at its bottom, and the actuator is preferably an electric initiator having a pyrotechnic charge.
Claims18
A quick-loosening mechanical linking device, comprising;
- a) a housing;
- b) a release cavity having a predetermined height and a bottom, and including an abutment at said bottom;
- c) a bolt disposed within said housing and having an attachment means projecting out from said housing, an intended failure zone, and a head with a piston face;
- and,
- d) an actuator for selectively providing a pressure within said device adequate to cause said bolt to move farther out from said housing by a distance equal to said predetermined height of said release cavity;
- wherein said bolt is a single unitary piece.
A quick-loosening mechanical linking device, comprising:
- a) a housing;
- b) a release cavity having a predetermined height;
- c) an abutment at the bottom of said release cavity;
- d) a bolt disposed within said housing and having an attachment means projecting out from said housing, a release zone, a head with a piston face, and a narrowed central portion between said head and said abutment, wherein said abutment is formed into said bolt;
- and
- e) an actuator for selectively providing a pressure within said device adequate to cause said bolt to move farther out from said housing by a distance equal to said predetermined height of said release cavity.
