Abstract:
PCT No. PCT/AU95/00310 Sec. 371 Date Nov. 25, 1996 Sec. 102(e) Date Nov. 25, 1996 PCT Filed May 29, 1995 PCT Pub. No. WO95/32891 PCT Pub. Date Dec. 7, 1995A trigger device enabling a larger actuating force to be restrained by a smaller control force comprises a housing in which is rotatably mounted a primary lever biased to rotate from a cocked position to a firing position by a tension spring. The tension spring is located such that the rotational bias to the primary lever is significantly greater in the firing position than in the cocked position. The trigger device is typically used for both automatic and manual release of compressed gas from a bottle to an inflatable life-saving aid by way of a piercing pin moved by a cam surface on a secondary lever which can be manually rotated by a toggle or automatically by the primary lever on the dissolving of a water-soluble tablet restraining the primary lever in the cocked position.
