ABSTRACT:
A door locking device has a shaft portion, a non-skid end portion adjustably connected to a lower end of the shaft portion, a door handle engaging bracket affixed to an end of the shaft portion opposite the end portion, and an alarm device mounted to the shaft portion so as to be responsive to shocks affecting the door handle. The alarm device has an audio output. The shaft portion includes an arcuate shape extending outwardly from the bracket, a straight section extending from the arcuate shape, and an angled section extending vertically downwardly from the straight section. The end portion is threadedly received by the angled section. The bracket has a generally U-shaped configuration with a prong formed interior of the U-shaped configuration. The alarm device includes a housing, an alarm emitter connected to the housing, and a shock-responsive trigger circuit positioned within the housing and electrically connected to the alarm emitter so as to pass a signal in response to shocks above a given threshold value.
