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 latch mechanism for securing a module in an electronic component chassis comprising:
two lever arms connected by a bridge and attached to the module, the lever arms 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;
two module hooks attached to the module;
two pawls rotably attached to the module such that when the lever arms are moved to the latched position, each lever arm rotates, contacting each pawl causing each pawl to rotate into a latched position wherein the pawl has an interference fit with the chassis;
wherein each lever arm includes a locking feature comprising a trigger hook engageable with the module hook to lock the latch mechanism in the latched position;
wherein the locking feature includes a spring loaded trigger to engage the trigger hook to the module hook and release the trigger hook from the module hook.
2. The latch mechanism of claim 1 wherein an attachment of at least one pawl to the module is spring loaded.
