Locking nose
The locking lug , also called the locking cam or cam , is an important component in the cylinder lock because the locking lug triggers the locking process.
functionality
In order to operate the lock cylinder, the locking nose in the lock rotates with it. In doing so, she can lift the spring-loaded bolt locking device so that the bolt moves. Turning the locking nose moves the bolt one turn until it engages in the guard locking again. This ends the closing process.
The turning operation of the locking nose is usually made possible by the key. And as soon as the key is removed from the lock, the cylinder blocks the locking lug.
Exception panic lock
The special design of the locking nose in panic locks is an exception . In this case, a locking cylinder is equipped with a so-called free - swing function. This means that the locking lug can also be operated in freewheel mode, i.e. even when no key is being used. This function is required for special profile cylinders in panic locks. Because in this way a locked door can only be opened in an emergency by pressing the door handle or the panic bar.
This special locking nose must be ordered separately in most systems.
Adjustable locking lugs
Half cylinders in particular are always offered with an adjustable locking nose. This option is relevant for the individual positioning of the locking nose. If this is adjustable, you can simply turn it into the desired position. It is important to position the locking nose at the right angle to the lock. This usually ranges from 0 ° to 315 °. Because this is the only way to ensure that the basic position of the locking nose corresponds to the conditions of the Hallbylinder lock.
