Abstract
Abstract A plate-like pawl blockingly engages between a pair of forked latch members, which are spring-biased toward one another to a position in which they encircle and latch a fixed automobile door keeper. The blocking part of the pawl is an integral plate component on a dogging arm of a heavy duty sheet metal stamping presenting three angularly divergent arms, the mentioned arm being undogged normally by a vertically shiftable, intermittent latch operator, disconnector and control slide when the lock is in an unlocked, non-freewheeling setting. To this end the slide has a laterally offset operating tab which is engageable for the purpose with an integral offset formation on a second de-dogging kick-off arm of the pawl, thus placing the latter in a latch releasing position. When the slide is cocked a bit transversely of its direction of longitudinal undogging shift, in a pivotal movement about a connection to an outside-operated bell crank, the slide overruns or free-wheels relative to the pawl arm''s offset, hence disables the pawl from unlatching the lock. For the purpose of thus cocking the slide, the latter is provided with an elongated slot which receives a laterally offset tang on one arm of a pivoted multi-arm locking lever whereby, upon a swing of that lever in a pawl-disabling and locking direction, the slide is shifted or cocked to its position to overrun the pawl arm offset. Otherwise, the tab of the slide operates to undog the pawl without interference from the locking lever tang, since the slide''s slot receiving said tang is elongated, in the unlocked setting, on the direct line of shift of the operator and disconnect slide, hence is idly overrun by the latter. The locking lever is selectively operated by inside remote control and key-operated lever connections. The outside operator is a bell crank type, on an arm of which a bottom portion of the disconnect slide has a fixed, rivet-type pivotal operating connection. An automatic feature is also incorporated to enable the door to be locked without key from the outside.
