Interference structure for emergency response system wristwatch

Abstract

An emergency response system wristwatch having upper and lower case sections connected by a hinge is combined with a removable interference bracket disposed between the two case sections. The upper case section has opposing rear and front surfaces, where the front surface includes a dial face. The upper case section is operable to pivot on the hinge between open and closed positions. The lower case section has an activation button that is exposed when the upper case section is in the open position. When the upper case section is in the closed position, the rear surface of the upper case section is disposed adjacent the activation button. Without the removable interference bracket between the upper and lower case sections, the rear surface of the upper case section is operable to move toward the lower case section and press upon the activation button if pressure is applied to the dial face. Housed within the lower case section is a wireless transmitter that is activated when the rear surface of the upper case section presses the activation button. When activated, the wireless transmitter transmits a wireless emergency signal. When the removable interference bracket is installed between the upper and lower case sections, the bracket prevents the rear surface of the upper case section from pressing the activation button if pressure is applied to the dial face. Thus, the interference bracket prevents accidental activation of the wireless transmitter due to inadvertent pressure upon the dial face.
