Lock with magnetically actuated latch movement preventing member
MOTOR DRIVEN LOCK FOR TRUCK DOOR
As seen in the drawings, the lock of the present invention includes a housing 10 consisting of a front wall 12, from which side walls 14 extend rearwardly, and a rear wall 16. The side wall 14a that faces the door jam 18 of the vehicle has an opening 22 through which the hook extends.
A latch rotation preventing member 58 is provided. Member 58 includes a substantially cylindrical upper body portion 58a and a lower, slightly smaller diameter, cylindrical portion 58b. Member 58 is moveable linearly along an axis 59, in a direction substantially parallel to the latch rotation axis 46.
Member 58 moves within tubular part 60, along axis 59, between a forward position, in front of the plane of front housing wall, where it is remote from the rotational path of latch body 32, and a rear position, where portion 58b extends through opening 72 in housing front wall 12 (see FIG. 3) such that portion 58b intersects the rotational path of latch body 32. Axis 59 of member 58 is parallel to axis 46 of shaft 36. In the rear position of member 58, member portion 58b abuts side surface 32a of latch body 32 to prevent the latch body from moving hook 34 to disengage vehicle part 48 (see FIG. 2). A spring 65 biases member 58 toward its rear position.
An opening 72 (FIG. 4) is provided in the portion of housing front wall 12 situated under housing section 70. Opening 72 is in the shape of two contiguous circles 72a and 72b. Opening section 72b has a smaller diameter than section 72a. The diameter of section 72b is large enough to permit passage of lower portion 58b of member 58, but not the upper, larger diameter portion 58a. Thus, the upper portion 58a of member 58 is retained within housing section 70, in front of housing front wall 12, whereas portion 58b of member 58 can protrude through opening portion 72b, into the interior of housing 10, to intersect the path of latch body 32, when member 58 is in the rear position.
Part 74 has a rim 80 which is inclined relative to the axis 82 of cylinder 66 and which is also the axis of rotation of part 74 (see FIG. 6). Rim 80 of part 74 acts as a cam surface for protrusion 64. Thus, as cylinder 66 rotates part 74, protrusion 64 rides along rim 80 causing member 58 to move back and forth along axis 59. When cylinder 66 is in the “locked” position, part 74 frees protrusion 64 such that spring 65 moves member 58 linearly to its rear position, with portion 58b extending through opening portion 72a and intersecting the path of latch body 32, preventing latch body 32 from rotating to cause hook 34 to disengage vehicle part 48. When cylinder 66 rotates from its “locked” position, part 74 rotates, causing protrusion 64 to move member 58 to its forward position, against the urging of spring 65, and portion 58b of member 58 to move out of the path of latch body 32, permitting latch body 32 to rotate and hook 34 to disengage vehicle part 48.
It will now be appreciated that because in the “locked” state of the mechanism of the present invention, spring 65 biases member 58 toward it rear position, causing portion 58b to intersect the path of movement of latch body 32. Insertion of a tool through the key opening in housing section 70 cannot move member 58 forward such that the latch body can be rotated, because member 58 has no portion that can be engaged by the tool to move the rotation preventing member forward. Accordingly, the lock cannot be breached in this manner.
