Morticed bolt keep and a closure system comprising the same

A morticed bolt keep configured to cooperate with a lock having a latch bolt which is slidable between a retracted position and an extended position, the morticed bolt keep comprising:

• an elongated body extending in a longitudinal direction and configured to be positioned inside a hollow tubular member which extends in the longitudinal direction;
• and
• a cavity inside the elongated body and configured to receive the latch bolt in its extended position,
• wherein the morticed bolt keep further comprises:
• a latch bolt engager mounted in the elongated body which is displaceable between a rest state and an actuated state;
• and
• a magnetic actuator mounted inside the elongated body and configured to displace the latch bolt engager from its rest state to its actuated state upon activation, the magnetic actuator comprising:
• a core which extends in the longitudinal direction and comprises:
• a frame comprising a first mounting space and a second mounting space separated by a frame part, wherein the first mounting space and the second mounting space are spaced apart from one another in the longitudinal direction by the frame part;
• a first permanent magnet mounted in the first mounting space;
• and
• a second permanent magnet mounted in the second mounting space, the permanent magnets being oriented such that their magnetic axis are perpendicular to the longitudinal direction and such that they attract one another in the longitudinal direction;
• and
• a coil assembly which extends in the longitudinal direction and comprises a first coil and a second coil,
• wherein one of the core and the coil assembly is slidable in the longitudinal direction and is operatively connected to the latch bolt engager.

• a core which extends in the longitudinal direction and comprises a permanent magnet which has a north pole and a south pole with a magnetic axis parallel to the longitudinal direction;
• and
• a coil assembly which extends in the longitudinal direction and comprises a first coil and a second coil separated from one another in the longitudinal direction, the first coil being disposed at least around the north pole and the second coil being disposed at least around the south pole, the coils having an opposite magnetic polarity,
• wherein one of the core and the coil assembly is slidable in the longitudinal direction and is operatively connected to the latch bolt engager.
