Remote activation mechanism for equipment hold down and release
First Claim
1. —
- A remote activation mechanism for equipment hold down and release, characterised by being composed of a fixed base;
a disk parallel to the fixed base with capacity to rotate;
a segmented ring mounted in between said fixed base and said disk;
an helical torsion spring mounted around said segmented ring, having one of its ends joined to said fixed base and the other to said disk;
a retainer to attach the equipment, that passes through said fixed base and has means to be blocked by said segmented ring;
a disk blocking system; and
a disk liberation system;
in which said disk can potentially rotate from a position in which said helical torsion spring is loaded hugging radially said segmented ring maintaining the segments as close as possible, up to a position in which said helical torsion spring is unloaded having a bigger internal diameter, allowing the ring segments move radially away; and
in which said retainer is maintained in position by said segmented ring when said segmented ring is in its closed configuration, and said retainer is released when said segmented ring is in opened configuration with its segments separated; and
in which said disk blocking system is composed of a trigger capable of not allowing the rotation of said disk; and
in which said disk liberation system consist of an actuator capable of activating the trigger and liberate said disk, discharging said helical torsion spring.

Abstract
Remote activation mechanism for equipment hold down and release, composed of a fixed base (1); a disk with capacity to rotate (2); a ring (3) subdivided in independent segments; a helical torsion spring (4) mounted around the segmented, being in one end joined to the fixed base (1) and the other end to the disk (2); a retainer (5) to attach the hardware, that passes through the fixed base (1) and has means to be blocked by the segmented ring (3); a disk blocking system; and a disk liberation system (2). The disk (2) can potentially rotate from a position in which the helical torsion spring (4) is loaded hugging radially the segmented ring (3), up to a position in which the helical torsion spring (4) is unloaded, allowing the ring segments move radially away to release the retainer (5). The disk blocking system can be based on rollers or balls (12) with possibility of being inserted partially in disk grooves or in crown grooves. The disk (2) liberation system consists of an actuator that can be based on the use of shape memory alloy wire.
