| 139 | Flip guard lock device and method of use | US13935007 | 2013-07-03 | US08794041B2 | 2014-08-05 | Ron R. Daniels |
| The present invention, and inventive system, is a new locking mechanism that prevents entry for doors, or other barriers that can use a deadbolt system, or system comparable to a deadbolt system. The present invention can be installed and works in conjunction with the existing deadbolt assembly to prevent lock picking, a bump key, or a user's own key from being used to open the door. In the present invention, by engaging the arm latch, or arm actuator, of the present invention, over the turn knob on an existing deadbolt, the present invention prevents the free rotation movement of the turn knob, thus not allowing retraction of the deadbolt, and entry through that door or barrier. | ||||||
