Abstract: A door guard for wedging an entry door into a closed position thereby preventing unauthorized, forced opening of the entry door. The door guard includes a base plate which rests on the floor area behind an entry door. A lower brace member is pivotally attached at one end to the base plate. An upper brace member is pivotally attached to the lower brace member with the upper brace member including a plastic coated yoke member which is placed under and partially around the doorknob of an entry door. A spring is positioned to coact between the upper and lower brace members to bias the brace members into an aligned relationship. The overall length of the door guard can be adjusted by connecting the upper brace member to the lower brace member at different openings along the lower brace member. After the upper and lower brace members are brought into an aligned relationship, a rectangular buckle lock is positioned to lock the members together.
