Description

Technical Field

The present invention relates to a motor-drive mechanism designed to fully deadlock and fully unlock multi-point slam (Automatic Throw) locks using a directly input security code, fingerprint recognition or activation from a mobile device via a secure App.

Background

Multi-Point Slam Lock door locks (MPSDL) are used in many neighbourhoods and homes. The main locking points are sprung and use a compression device to throw them into the door frame plates when the door is fully closed. The locking points individually deadlock but the main drive mechanism requires a further turn of the key to fully deadlock.
To gain entry, a traditional key operation is required to fully unlock the (MPSDL) and withdraw the latch. The key is also required to complete the final deadlock.
Smart locking systems are gaining in popularity, giving keyless entry and exit and remote locking and unlocking of standard type multi-point locks. In recent years, most of the major lock manufacturers have introduced (MPSDL) to their product ranges.
There are currently no Smart motor drive operating mechanisms designed specifically for (MPSDL) systems, as current smart products are designed to lock either after the handle lever has been manually thrown (lever lift MPL) or by two full turns of the drive cylinder to fully throw the MPL locking points (key wind MPL).
