A hand-held
security alarm system for sounding an alarm when the
system is released. The hand-held
security alarm system includes a hand-held device that contains an alarm, a battery, an activation member, an activation
electronic circuit, an alarming member, and a deactivation button. The activation member being biased to push away from the hand-held device by a compression spring. The activation
electronic circuit being activated by an activation switch when the activation member travels a certain distance from the hand-held device. The hand-held device is maintained in the inactive state by the activation member being held against the hand-held device by a
detent incorporated into the alarming member. The hand-held device is put into the armed position by sliding the alarming member so that the
detent on the activation member travels past a catch on the activation member and the activation is held against the compression spring by an external force such as a hand grasping the hand-held device. The hand-held device once armed is activated by releasing the external force on the activation member so that the compression spring pushes the activation member away from the hand-held device thereby triggering the
electronic circuit and causing the battery to energize the alarm causing an audible sound. The electronic circuit cannot be deactivated by pressing the activation member back towards the hand-held device but requires the application of a deactivation switch which when pushed opens the electronic circuit
cutting the battery power from the alarm. The hand-held device includes a strap that can be securely attached to the body of the user so that in an
attack the hand-held device stays with the user.
