Definitions
- the present invention relates to an electromagnetic lock.
- a lock has two parts, one of which is fixed while the other is fixed to the element whose closing is to be controlled, such as a door.
- the fixed part of the lock consists of an electromagnet and the other part of a metal frame which can be moved against a return spring.
- armature When the armature is facing the electromagnet and the latter is excited, said armature is attracted and the door cannot be maneuvered, because the force to be developed to tear off the armature is much greater than that which can be provided by a normal user.
- the lock of the invention which overcomes these drawbacks, is characterized by the use of a conventional armature comprising a return spring holding said armature and the electromagnet spaced from one another when said electromagnet is not not excited and in that one of the elements of the lock comprises, at least, a linear boss extending parallel to the direction of movement of the movable part capable of penetrating into a corresponding housing, provided on the other part, when the two said parts are in coincidence, the height of the said boss being less than the distance separating the latter when the electromagnet is not excited.
- FIG 2 is the left view of Figure 1;
- FIG. 3 is an elevation view of the other part of the lock
- FIG 4 is the left view of Figure 3;
- FIG. 5 is a view in elevation of a lock according to the invention, the electromagnet not being excited.
- FIGS. 6A, 6B, 6C and 6D are sectional views taken along line VI-VI of FIG. 5.
- the lock consists of two parts 1 and 2, part 1 comprising the electromagnet and that 2 comprising the movable armature 3 which is normally called back to the fixed base.
- the boss 6 extends from one edge 7 to near the other edge 8 of the part 1 and its height is less than the distance separating the two parts 1 and 2 when the electromagnet is not excited, as shown in Figure 5.
- part 1 is fixed on the frame of the opening and that part 2 is fixed on the door.
- part 2 moves substantially along the arrow F and the electromagnet is excited.
- Part 2 passes smoothly from the position shown in Figure 6A to that of Figure 6B because the usual springs for returning the armature are calibrated so that the action of the electromagnet has no effect on the armature 4 as long as the latter does not have a certain surface facing said electromagnet.
- this result is obtained by providing on the part 1 a boss 1 1, similar to that 6 but extending from the edge 8 to near that of 7, capable of cooperating with a housing 12 similar to that 9 .
