Fatigue alarm

A fatigue alarm, comprising,

• a housing, the housing having a top wall spaced from a bottom wall, and a surrounding wall directed coextensively between the top wall and the bottom wall to define a housing cavity within the housing, and
• a first handle plate fixedly mounted to the housing, and
• a second handle plate received through a slot in the bottom wall permitting movement of the second handle plate through the bottom wall, and
• a spreader member positioned within the housing cavity and extending between and secured to the first handle plate and the second handle plate and arranged to bias the first handle plate and the second handle plate in a spaced relationship relative to one another, and
• a first electrical contact secured to the second handle plate, and a second electrical contact secured to the surrounding wall within the cavity, such that said spreader member effects biased separation of the first handle plate relative to the second handle plate to direct contiguous communication of the first electrical contact with the second electrical contact, and
• an audio alarm device mounted within the cavity in electrical communication to the first electrical contact and the second electrical contact, whereupon communication of the first electrical contact to the second electrical contact is arranged to effect actuation of the audio alarm;
• said spreader member including a tube head secured to the second handle plate and a rod head secured to the first handle plate, with a rod secured to the rod head and a tube secured to the tube head, with the rod reciprocatably directed through the tube and a spring member captured between the tube head and the rod head to bias the first handle plate in a spaced relationship relative to the second handle plate to effect contiguous communication of the first electrical contact and the second electrical contact.
