Door latch mechanism

Claim 2

In a vehicle body having a door, a door lock mounted on the door and including a lock frame, a detent swingably mounted on the frame for movement between holding and released positions with respect to a latch bolt mounted on the frame for movement between latched and unlatched positions, an inside latch release means and an outside latch release means for the door lock mounted on the door, the combination comprising, an inside release lever pivotally mounted on said lock frame and operatively connected to said detent, an actuator lever movably mounted on said frame and operatively connected to said inside latch release means, coupling means mounted on said lock frame connected to said outside latch release means and connectable to said detent, primary locking means mounted on said frame for selectively coupling said coupling means to said detent, secondary locking means positioned to engage said primary locking means, and inside operated garnish button control means operatively connected to said secondary locking means and said inside release lever, said garnish control means being movable from a first position in which said inside latch release means and said outside latch release means are operative to effect release of said detent, to a second position in which only said outside latch release means is operable to effect release of said detent and to a third position in which said inside latch release means and said outside latch release means are inoperable to effect release of said detent; said garnish button control means including an inside operating garnish button mounted for movement from said first position to said second position and to said third position, a bellcrank coaxially mounted on said frame with said secondary locking means and operatively connected to said inside operating garnish button, an overcenter spring connected between said bellcrank and said secondary locking means, link means pivotally connected at one end to said bellcrank and slideably connected to said secondary locking means and at the other end thereof slideably connected to said release lever whereby said other end of saiD link means is slideable from a first position with respect to said release lever in the path of movement of said actuator lever to a second position out of the path of movement of said actuator lever.

Claim 3

The combination of claim 1 wherein said link means includes pin means at one end thereof connecting said link means to said bellcrank, said secondary locking means having a slot therein to receive said pin to selectively connect said bellcrank to said secondary locking means, a slot in said inside release lever to slideably receive said other end of said link means, movement of the inside release lever by said detent upon movement of said detent by said latch bolt as said latch bolt is moved to said latched position causing said slot in said inside release lever to cam said link means to said second position out of the path of movement of said actuator lever and to position said inside operating garnish button in said second position.

Claim 4

In a vehicle body having a door, a door lock mounted on the door and including a lock frame, a detent swingably mounted on the frame for movement between holding and released positions with respect to a latch bolt mounted on the frame for movement between latched and unlatched positions, an inside latch release means and an outside latch release means for the door lock mounted on the door, the combination comprising, an inside release lever pivotally mounted on said lock frame and operatively connected to said detent, an actuator lever pivotally mounted on said frame, means operatively connecting said actuator lever to said inside latch release means, coupling means connected to said outside latch release means, primary locking means mounted on said frame for selectively coupling and uncoupling said coupling means with said detent, secondary locking means positioned to engage and move said primary locking means to effect said coupling and uncoupling, inside operator means mounted for movement between a first position, a second position and a third position, actuator means coupling said inside operator means to said inside release lever and said secondary locking means whereby when said inside operator means is in said first position, said inside latch release means and said outside latch release means are operative to effect release of said detent, when in said second position said outside latch release means is operative to effect release of said detent and when in said third position, both said inside latch release means and said outside latch release means are rendered inoperative to effect release of said detent; said actuator means including crank means mounted on said frame, adjacent said secondary locking means, link means, pin means pivotally connecting one end of said link means to said crank means and slideable with said secondary locking means, the opposite end of said link means being slideably received in a slot in said inside release lever for movement from a first position whereby said actuator lever is operatively connected to said inside release lever to a second position in which said actuator lever is operatively disconnected from said inside release lever and, whereby movement of said detent by said latch bolt moving to said latched position causes movement of said inside release lever to cam said link means to said second position and to effect movement of said inside operator means to said second position of said inside operator means.

Claim 5

In a vehicle body having a door, a door lock mounted on the door and including a lock frame, a detent swingably mounted on the frame for movement between holding and released positions with respect to a latch bolt mounted on the frame for movement between latched and unlatched positions, an inside latch release means and an outside latch release means for the door lock mounted on the door, the combination comprising, an inside release lever pivotally mounted on said lock frame and operatively connected to said detent, an actuator lever pivotally mounted on said frame, means operatively connecting said actuator lever to said inside latch release means, coupling means connected to said outside latch release means, primary locking means mounted on said frame for selectively coupling and uncoupling said coupling means with said detent, secondary locking means positioned to engage and move said primary locking means to effect said coupling and uncoupling, inside operator means mounted for movement between a first position, a second position and a third position, actuator means coupling said inside operator means to said inside release lever and said secondary locking means whereby when said inside operator means is in said first position, said inside latch release means and said outside latch release means are operative to effect release of said detent, when in said second position said outside latch release means is operative to effect release of said detent and when in said third position, both said inside latch release means and said outside latch release means are rendered inoperative to effect release of said detent; said actuator means including crank means mounted on said frame, adjacent said secondary locking means, link means, pin means pivotally connecting one end of said link means to said crank means and slideable with said secondary locking means, the opposite end of said link means being slideably received in a slot in said inside release lever for movement from a first position whereby said actuator lever is operatively connected to said inside release lever to a second position in which said actuator lever is operatively disconnected from said inside release lever and, whereby movement of said detent by said latch bolt moving to said latched position causes movement of said inside release lever to cam said link means to said second position and to effect movement of said inside operator means to said second position of said inside operator means.
