Portable door alarm
First Claim
1. A portable door alarm comprising:
- a housing having a front side and a back side;
an alarm pushbutton switch extending out from the back side of the housing having a depressed stated and an unpressed state;
a first L-shaped member having a longitudinal portion with a bracket hanger attached at a top end thereof;
a second L-shaped member having a longitudinal portion with a leg portion extending therefrom along a top end thereof;
means for attaching said second L-shaped member to the back side of said housing;
an opening within the longitudinal portion of said second L-shaped member for allowing said alarm pushbutton switch to extend therethrough;
a hinge having a first end thereof connected to a bottom end of said first L-shaped member and a second end thereof connected to a bottom end of said second L-shaped member, said hinge having a closed position maintaining the first L-shaped member in its normal position proximate to said back side of said housing and adjacent to said second L-shaped member;
an engaging member extending from said longitudinal portion of said first L-shaped member to said alarm pushbutton switch for contacting said alarm pushbutton switch thereby placing said alarm pushbutton switch in its depressed state when said first L-shaped member is located in its normal position adjacent to said second L-shaped member;
a biasing member for urging said first L-shaped member to maintain its normal position;
an audible signal generator for producing a distinct audible signal when activated; and
alarm control circuitry having an alarm set state and an alarm unset state, said alarm control circuitry activating said audible signal generator when said alarm pushbutton switch is located in its depressed state and said alarm control circuitry is in said set state.

Abstract
A portable door alarm having an alarm pushbutton switch extending from the back of the housing of the alarm has a first L-shaped member hingeably attached to a bottom portion of the housing. At the top of the first L-shaped member is a bracket hanger which fits over the top of a door. The first L-shaped member is biased to close the hinge, thereby placing the first L-shaped member in close proximity to the housing. A leg portion of a second L-shaped member, having a longitudinal portion attached to the back of the housing, is located above the hanger and pushes against a wall portion above the door once the device is placed on the door and the door is closed. If the door is reopened, with the alarm set, an engaging portion of the first L-shaped member presses the alarm pushbutton switch as the L-shaped member returns to its close proximity to the back of the housing due to the biasing thereof. An alarm sounds once the engaging portion depresses the alarm pushbutton switch with the alarm set.
