Multiple location latch mechanism with single actuation
View Patent ↗A latch mechanism for securing a module in an electronic component chassis includes at least one lever arm attached to the module and rotable between a latched and unlatched position, at least a portion of the lever arm having an interference fit with the chassis when the lever arm is in the latched position. The latch mechanism further includes at least one pawl rotably attached to the module such that when the lever arm is moved to the latched position, the lever arm rotates the pawl into a latched position wherein the pawl has an interference fit with the chassis.
1. A method for securing a module in an electronic component chassis comprising:
rotating two lever arms connected by a bridge and attached to the module from an unlatched position toward a latched position, each lever arm thereby contacting one of two pawls rotably attached to the module;
rotating the two pawls into a latched position wherein each pawl has an interference fit with the chassis;
rotating the two lever arms into the latched position wherein at least a portion of each lever arm has an interference fit with the chassis;
moving a spring loaded trigger of a locking feature attached to each lever arm thereby moving a trigger hook disposed on each lever arm into engagement with one of two module hooks attached to the module to lock the two lever arms in the latched position; and
releasing the spring loaded trigger thereby moving the trigger hook out of engagement with one of the two module hooks to move the two lever arms toward the unlatched position.
2. The method of claim 1 wherein the attachment of each of the two pawls to the module is spring loaded.
