<p>An electric lock of the swingable latch type, in that the latch (8) is biased by a spring (10) into its door-opening position, but is held into its door-locking position by the suitably shaped projecting portion (12) of an associated member (108) engaged in means (113) at one end of, and integral with lever (13) fulcrumed about pivot (14) parallel to pivot (6) pivotably supporting the latch (8), and biased by a spring (16) in the proper direction for engagement of means (113) with the projecting portion (12) of member (108), and into engagement through the stepped portion (19) formed in its opposite end remote from latch (8) with the top end of a flat lever (20) of ferromagnetic material, provided with lateral appendices (120-120 min ) respectively extending at right angles from the top and bottom end thereof, with their axis being parallel to the pivots (14 and 6), and by which the lever (20) is swingably mounted in circular seats (21-21 min ) at the upper and lower end of the wings of the support member (5), the top end of lever (20) being swung into engagement with the stepped portion (19) of lever (13) by the plungers (122-122 min ) of solenoids (22-22 min ) axially urged by springs (24) toward lever (20), and being drawn out of engagement with the said stepped portion (19) by the activation of solenoids (22-22 min ), resulting in the plungers (122-122 min ) being drawn into the interior of the respective solenoid (22-22 min ), whereby the latch (8) is swung into its door-opening position.</p> |
