Introduction
David A Sorensen is a notable inventor based in Hamden, CT (US). He has made significant contributions to the field of lock mechanisms, holding a total of five patents. His innovative designs focus on enhancing the functionality and durability of locking systems.
Latest Patents
One of his latest patents is the high strength lever handle lock mechanism. This lock mechanism is designed for use with lever handles and includes a lock core and a latch mechanism that is rigidly connected to the lock core. This design prevents the lock core from rotating in the door, eliminating the need for through-bolts and allowing for a small diameter rose. The mechanism features stops and a spring return mechanism that are entirely located within the lock core, enabling a thinner rose. The lock core defines the rest position for the lever handles at an angle slightly above horizontal. To simplify production, the lock core is made substantially symmetrical about a vertical plane, allowing the inner and outer sides of the lock mechanism to be interchanged. Additionally, a heavy-duty locking piece with locking lugs engages the lock core near its inner perimeter, ensuring the lock can withstand abusive forces applied through the lever handle. Endplay is nearly completely eliminated, providing a quality feel through the use of collars that connect the interchangeable inner and outer sides of the lock to the lock core.
