ABSTRACT:
A self-contained, portable, safety alarm device adapted to be worn on a user's hand for providing an alert signal when, through drowsiness or otherwise, the user's hand relaxes. The device includes at least a partial glove including a fingertip portion adapted to be worn on at least one fingertip of the user, a wristband portion adapted to be worn about the user's wrist, and connecting means connecting the fingertip portion to the wrist portion.
The wristband supports a housing which includes a battery, an alarm device energized by the battery, and an on-off switch. The fingertip portion supports a switch electrically connected to the battery and alarm device which provides an open circuit when the user holds the switch against a contact surface, for example, a steering wheel of a vehicle, and provides a closed circuit to permit the battery to energize the alarm device when the user's hand relaxes away from the contact surface. The wristband includes an optional test light for testing the charge condition of the battery and an earphone apparatus for connecting the alarm device directly to the user's ear.
The safety alarm device is particularly adapted for use by long distance drivers, machine operators, and others that may be required to stay alert over long periods of time.
