  • Patent number: 10119299
    Abstract: A pickproof lock has a hollow housing, a lock shaft and a sleeve mounted in the housing, multiple axial pin sets mounted in the lock shaft and the sleeve, and at least one radial pin set mounted in the housing and the lock shaft. When unlocking the pickproof lock, the key is able to push the axial pin sets and the at least one radial pin set to unlocking positions, so as to drive the lock shaft to rotate and to unlock the pickproof lock. The complexity of the pickproof lock is increased. People with bad intentions are unable to unlock the pickproof lock with a lock picking tool, such as a round tube. Accordingly, personal goods or private matters can be safely protected by the pickproof lock.

  • Patent number: 9527130
    Abstract: A method for coding components of a locking system which are used to code a key and a female lock part. The coding components may be formed integrally with the key and female lock part or be provided as coding discs that are then affixed to non-coded bodies used for the key and female lock part. A blank of an easily machinable preliminary material is separated into two coding parts with a separation cut that simultaneously creates a coding surface on each coding part. These coding parts serve as the model to mold the coding components in a lost-wax process. Each coding part is encased in a material that forms a mold shell. The coding part is then melted or gasified and escapes from the mold shell, which now has a mold cavity that is then cast with the final material to be used for the coding components.

    Abstract: The decoding of a lock, such as a pin tumbler type of lock, is completed by utilizing a method that includes the insertion of a key blank or other material with one or more reference indicators on a modifiable surface, into a keyway of the lock. The key blank is inserted until a stopping resistance is detected. Such a resistance occurs when a pin of the lock reaches a shear line position. After such a position is reached a marking is made on the key blank and a measurement is made. The measurement is compared to markings on a novel decoding template to determine the depth of a cut that should be made on an uncut key.
