Latest Patents

One of his latest inventions is a mortise lock that features a reinforcing plate. This plate enhances the structural rigidity and robustness of the lock, making it resistant to external destructive pulling forces. The reinforcing plate is strategically placed in abutment with an exterior cover and a door panel, mounted on a mounting post of the exterior cover. It also includes a notch to receive and engage a key lock. Additionally, a securing plate may be positioned between the door panel and the main body of a torsional returning unit, which is connected to an exterior handle, further increasing structural rigidity.

Another significant invention is a re-keyable cylinder lock. This lock incorporates a control member that allows for the transverse movement of a re-keying unit. The control member can move axially between first and second positions and transversely to a third position from the second position. In the third position, the re-keying unit disengages from the first tumbler pieces. A limit member is included to prevent the control member from moving axially when the correct key is not inserted into the plug. Furthermore, a security arm connected to the control member is designed to be breakable, ensuring that destructive forces cannot reach the control member.
