发明名称 Door brace
摘要 A device for bracing a door against being forced open from the outside is an extensible rod having a floor-gripping member on one end and a door handle-gripping pair of jaws on the opposite end. The pair of jaws are pivotally mounted and shaped so that opposing edges of the jaws are wedged into clamping engagement with the door handle with a force proportionate to the force being used to push the door against the brace.
