Mechanism for rapid de-coupling of load bearing structures

A de-coupling mechanism, comprising:

• a link slidably received in a link aperture created in a member;
• a pin slidably received in each of a pin bore created in the link and a receiving bore formed in the member to releasably retain the link in a first position;
• a first block connected to the member, the first block including an initiator receiving passage in communication with the pin bore;
• an initiator positioned in the initiator receiving passage and retained against an edge of where a connecting passage and the initiator receiving passage meet, the initiator when actuated releasing a pressurized gas displacing the pin out of the pin bore into a longitudinal channel, thereby releasing the link from the first position;
• a channel created in the link in communication with a bore created in the link;
• a tube connected to the member, the tube having an axially adjustable plug;
• wherein the channel in the link and the tube each communicate with the link aperture in the member;
• and wherein the connecting passage is between the initiator receiving passage and the pin bore.

• a spring retention member connected to the member, the receiving bore extending through the spring retention member,
• wherein the connecting passage is between the initiator receiving passage and the pin bore;
• a channel created in the link in communication with a bore created in the link;
• and
• a tube connected to the member, the tube having an axially adjustable plug;
• wherein the channel in the link and the tube each communicate with the link aperture in the member.

A de-coupling mechanism, comprising:

• a link slidably received in a link aperture created in a bracket;
• a pin slidably received in each of a pin bore created in the link and a receiving bore formed in the bracket to releasably retain the link in a link first position;
• a first block connected to the bracket, the first block including an initiator receiving passage in communication with the pin bore;
• an initiator positioned in the initiator receiving passage and retained against an edge where a connecting passage and the initiator receiving passage meet, the initiator when actuated releasing a pressurized gas acting to displace the pin out of the pin bore into a longitudinal channel, and thereby releasing the link from the first position to freely slide with respect to the bracket;
• a spring retention member connected to the bracket, the receiving bore extending through the spring retention member,
• wherein the connecting passage is between the initiator receiving passage and the pin bore and wherein the connecting passage, the initiator receiving passage, and the pin bore are coaxially aligned;
• a channel created in the link in communication with a bore created in the link;
• and
• a tube connected to the member, the tube having an axially adjustable plug;
• wherein the channel in the link and the tube each communicate with the link aperture in the bracket.

• a spring retention member connected to the member, the receiving bore extending through the spring retention member,
• wherein the spring retention member includes a step diameter smaller than a diameter of the longitudinal channel and smaller than a diameter of the pin, the pin being retained by the spring retention member upon displacement from the pin bore, wherein the spring retention member includes a passage to atmosphere opposite the pin, prior to the displacement of the pin;
• wherein the connecting passage is between the initiator receiving passage and the pin bore;
• a channel created in the link in communication with a bore created in the link;
• and
• a tube connected to the member, the tube having an axially adjustable plug;
• wherein the channel in the link and the tube each communicate with the link aperture in the member.
