Abstract
A pill for an automatic inflator employing a bobbin having at least one pivotal arm to hold-back a spring-loaded actuator pin in its cocked position, the pill including a major portion to retain and hold the pivotal arm of the bobbin in a cocked position and a minor portion comprising a fusible segment, and a heater wire positioned contiguous to said minor portion to fuse to the minor portion when electrical energy is supplied to said heater wire, thereby allowing the pivotal arm of the bobbin to move from a cocked position to a fired position.
Claims12
A pill for an automatic inflator employing a bobbin having at least one pivotal arm to hold-back a spring-loaded actuator pin in its cocked position, comprising in combination:
- said pill including a major portion to retain and hold the pivotal arm of the bobbin in a cocked position and a minor portion comprising a fusible segment;
- and
- a heater wire positioned contiguous to said minor portion to fuse to the minor portion when electrical energy is supplied to said heater wire, thereby allowing the pivotal arm of the bobbin to move from a cocked position to a fired position.
An automatic inflator, comprising in combination:
- a bobbin comprising a circular housing having internally a collapsible annular ring of individually pivotal arms extending generally parallel to the axis of the bobbin;
- a toroidal pill positioned about the ring of individually pivotal arms to retain them in their un-collapsed, generally parallel position and to prevent them from collapsing outwardly, the individually pivotal arms each including an inwardly extending radial step, which collectively form an annular seat to retain a spring-loaded actuator in its cocked position;
- said toroidal pill comprising a major portion and a minor portion, said major portion retaining and holding the ring of individually pivotal arms in their un-collapsed, generally parallel position and to prevent them from collapsing outwardly;
- and
- a heater wire positioned contiguously with said minor portion of said toroidal pill to be melted by electrical energy flowing through said heater wire when said automatic actuator senses water.
