Title: Innovations of Robert Harold Hanneman
Introduction
Robert Harold Hanneman is a notable inventor based in Wind Lake, WI (US). He has made significant contributions to the field of lock technology, holding a total of 3 patents. His work focuses on enhancing security mechanisms through innovative designs.
Latest Patents
Hanneman's latest patents include a pin tumbler cylinder lock with shearable assembly pins and a method for its operation. This invention allows for a turnable lock that operates with driver and tumbler pins when positioned by a key at a shear line. The shearable assembly pins are designed to be assembled in the lock and subsequently sheared to form the driver and tumbler pins necessary for operation. Each assembly pin is selectively weakened at various locations that correspond with the notched depth heights of the family of keys that can be inserted into the keyhole. This innovative design ensures that pin shearing can be accomplished by applying rotational or linear forces to any part of the lock, except for the key itself. When linear forces are applied, the tumbler or plug can be indexed to utilize a driver pin as a plug lock.
