Door Knob Shackle
Abstract 10007] The disclosed Door Knob Shackle is a two half spherical concave device that comes together to resemble a complete doorknob. Once applied over doorknob and a locking mechanism like pad locks are added, the device will render the door knob non-functional by way of stoping any grip or purchase that would enable the knob to be turned. See below 3D models and photo of working Door Knob Shakle
