    Abstract: This latch and lock means includes a magnetized bolt and a strike in which at least a part thereof is either magnetized and of opposite polarity from the bolt or is of material magnetically attractable to the bolt. The bolt is movable in a bolt housing of magnetically attractable material. It is moved by magnetic attraction to a door locking position within the strike member when it is aligned with the same by closing of the door and is yieldingly held there by magnetic attraction. In addition pawl means is provided to positively secure the bolt against retraction by picking methods using thin instruments inserted between the edge of the door and the jamb. Extensible pull back members, normally held contracted relative to each other by spring means, will first release the pawl means and then retract the bolt in response to a key or knob actuated pull. Magnetic attraction between the bolt and bolt housing will hold the bolt retracted when the door is open.

    Abstract translation: 该闩锁和锁定装置包括磁化螺栓和撞击，其中至少一部分被磁化并且与螺栓相反极性或具有磁性吸引到螺栓的材料。 螺栓可在可吸磁材料的螺栓壳体中移动。 当它通过关闭门与其对齐时，它被磁吸引移动到打击构件内的门锁定位置，并且通过磁吸引力而令人满意地保持在那里。 此外，提供棘爪装置以通过采用插入在门的边缘和边框之间的薄的装置的方法来确保螺栓不会收缩。 通常通过弹簧装置相对于彼此收缩的可拉伸拉回构件将首先释放棘爪装置，然后响应于钥匙或旋钮致动拉动而撤回螺栓。 当门打开时，螺栓和螺栓壳体之间的磁吸力将保持螺栓缩回。

    Abstract: A locking lever control arrangement on a vehicle door having a latch mechanism with a locking lever which automatically returns from an unlocked to a locked position upon closing movement of the door includes a three position internal control member on the door inner panel, a two position external control member on the door outer panel, a bellcrank, a blocking member and draft links connecting the internal control member to the bellcrank, the bellcrank to the locking lever and the bellcrank to the blocking member. The external control member is operable to move the locking lever from locked to unlocked position and the internal control member is operable upon movement to one position to rotate the blocking member to a blocking position preventing movement of the external control lever and upon movement to another position to move the locking lever from locked to unlocked position, and the locking lever is operable upon automatic movement from the unlocked to the locked position to move the internal control member to the third of the three positions thereof.
