Abstract
A pin pulling device moves a member such as a pin or shaft by a non-pyrotechnic actuation force, such as a spring(s). The actuation member or spring(s) is (are) held in the compressed and loaded position by a release mechanism, such as an explosive bolt coupled to the member through a retainer. When activated by a signal, the release mechanism is severed from the retainer and the member is actuated by the force of the actuation member or compressed springs as the springs expand.
Claims14
A pin puller device comprising:
- a housing;
- a non-pyrotechnic actuation mechanism having a longitudinal axis disposed within the housing;
- a release mechanism comprising an explosive bolt having a longitudinal axis constructed to initiate the release of the actuation mechanism in response to an activation signal;
- the release mechanism and the actuation mechanism being disposed in a relatively non-coaxial manner;
- and
- a pin or shaft member operatively associated with the actuation mechanism.
