Magnetic card-operated door closure

A handle operable door closure including a magnetic code lock cylinder of a lock for receiving a magnetically coded card and a rotatable first shaft, said lock cylinder for coupling to said rotatable first shaft which retracts a door latch, said first shaft being arranged to extend into a door having two parallel major surfaces, said first shaft having a rotational axis for being generally at right angles to said major surfaces, a surface mounted face plate arranged to be fixed to one of said major surfaces and to support a handle, the improvement comprising:

• a handle shaft rotatable about an axis laterally displaced from and parallel to said axis of said first shaft;
• a gear mechanism mounted behind said face plate;
• said handle shaft engageable by said gear mechanism;
• and
• a cam plate for engagement by said card upon its insertion into said lock cylinder and a clutch plate for engagement by said cam plate, to drivingly connect said gear mechanism to said first shaft to rotate said first shaft only when said magnetic lock cylinder has been placed in an unlocked condition established by insertion of said magnetically coded card into said lock cylinder.
