Abstract
A modular latch system has an activation module comprising an activation rod, a latch module comprising a biased latch, and a control cable connecting the activation module to the latch module so that rotation of the activation rod can retract the latch.
Claims14
A modular latch system, comprising:
- an activation module comprising an activation rod;
- a latch module comprising a biased latch;
- and
- a control cable connecting the activation module to the latch module so that rotation of the activation rod can retract the latch;
- wherein the latch comprises a longitudinal channel configured to capture a cable end of the control cable and wherein the cable end can be moved longitudinally relative to the latch without moving the latch;
- wherein the latch module comprises a latch handle connected to the latch and wherein actuation of the latch handle can move the latch without requiring rotation of the activation rod.
3 more elements
An aircraft door, comprising:
- an interior panel;
- an exterior panel connected to the interior panel to define an interior of the door;
- an activation module carried by the interior panel, the activation module comprising an activation rod;
- a latch module carried by the interior panel at a location remote from the activation module, the latch module comprising a biased latch;
- and
- a control cable connecting the activation module to the latch module so that rotation of the activation rod can retract the latch;
- wherein the latch comprises a longitudinal channel configured to capture a cable end of the control cable and wherein the cable end can be moved longitudinally relative to the latch without moving the latch;
- wherein the latch module comprises a latch handle connected to the latch and wherein actuation of the latch handle can move the latch without requiring rotation of the activation rod.

- an exterior panel connected to the interior panel to define an interior of the door;
- an activation module carried by the interior panel, the activation module comprising an activation rod;
- a latch module carried by the interior panel at a location remote from the activation module, the latch module comprising a biased latch;
- a control cable connecting the activation module to the latch module so that rotation of the activation rod can retract the latch;
- a conversion block carried by the activation rod, the conversion block comprising cable tabs configured for connection to the control cable, wherein the cable tabs receive retain a cable end of the cable;
- a lock carried by the exterior panel;
- and
- a lock tab carried by the conversion block, wherein the lock selectively prevents rotation of the activation rod by selectively obstructing rotation of the lock tab.
