发明名称 Keyless door knob security device with stabilizer arm
摘要 A new keyless door knob security device with stabilizer arm for preventing access to a keyhole of a door knob to prevent unauthorized access. The inventive device includes a central shaft that has first and second ends and a longitudinal axis extending between the ends. A claw ring has a plurality of claws extending outwardly from it and an aperture through it. The central shaft extends through the aperture of the claw ring. The claws are adapted for grasping the door knob. A cover is slidably positionable along the central shaft such that sliding the cover in a first direction presses the claws towards each other such that the claws grasp the door knob. Sliding the cover in a second direction permits the claws to move apart from each other. A locking mechanism permits selective locking of the cover in a locked orientation and an unlocked orientation.
