Electromagnetically controllable safety lock
First Claim
1. An electromagnetically controllable safety lock for containers for valuables, comprising a locking bar having a passage pin, and an electromagnet acting as a retaining magnet, said electromagnet blocking or releasing the retraction of the locking bar via controlling and blocking elements, wherein a driving nut moves a slider provided with teeth and driving along a blocking plate provide with a passage pin channel, said blocking plate being coupled via a spring with a control plate having an angularly offset passage pin channel, said control plate supporting an armature, said armature being retained by the electromagnet when current is applied, causing both channels to be aligned with the lock axis and permitting the passage pin with the locking bar to pass.

Abstract
An electromagnetically controllable safety lock includes a locking bar which moves a slider, which is provided with teeth and which carries a blocking plate equipped with a passage pin channel. The blocking plate is coupled via a spring to a control plate, which has an angularly offset passage pin channel. The control plate supports an armature, which can be held by an electromagnet, fixed to the housing when the locking bar is subjected to a control movement. Both channels are aligned with the lock axis during an opening action so that the passage pin has a free path.
