Dual pull latch assembly
A dual pull latch assembly and method of unlatching a panel. The double cable pull assembly includes a pull rod, a selector lever, and a linkage, wherein the selector lever is selectively disposed in a first feature or second feature of the linkage. In another embodiment, the double pull latch assembly includes a release arm, a lever, and a hold open lever to hold the lever in the intermediate position.
1. A double cable pull assembly configured for use with a double pull latch assembly, comprising:
a pull rod configured to translate between a first position and a second position through application of a force to the pull rod;
a selector lever having a selector lever end, wherein the selector lever is rotatably attached to the pull rod;
a linkage with a first feature and a second feature, wherein the selector lever end is selectively disposed in the first feature or the second feature;
a first cable attachment to receive a first cable;
a second cable attachment to receive a second cable, wherein the first cable and the second cable are configured to perform a respective action when they are actuated by the double pull latch assembly;
wherein, when the pull rod is pulled a first time, the pull rod will move the selector lever to engage the first feature to rotate the linkage in a first direction, pulling the first cable attachment;
wherein after the pull rod is pulled a first time, the selector lever is disposed about the second feature of the linkage; and
wherein, when the pull rod is pulled a second time, the pull rod will move the selector lever to engage the second feature to rotate the linkage in a second direction, pulling the second cable attachment.
2. The double cable pull assembly of claim 1 , further comprising a pull rod spring associated with the pull rod to urge the pull rod to the first position.
3. The double cable pull assembly of claim 1 , further comprising a selector lever pivot to rotatably couple the selector lever to an end of the pull rod.
4. The double cable pull assembly of claim 1 , wherein the linkage includes a linkage profile to guide the selector lever end.
5. The double cable pull assembly of claim 1 , wherein the first cable attachment includes a first cable attachment engagement feature to receive the selector lever end.
6. The double cable pull assembly of claim 1 , wherein the second cable attachment includes a second cable attachment engagement feature to receive the selector lever end.
7. The double cable pull assembly of claim 1 , further comprising a return spring associated with the linkage to rotate the linkage to a first position.
8. The double cable pull assembly of claim 1 , wherein a pull cable is operatively secured to the pull rod.
9. The double cable pull assembly of claim 1 , wherein the pull rod is operatively secured to an actuator.
10. The double cable pull assembly of claim 1 , wherein the pull rod is pulled by a user pulling a pull cable operatively coupled to the pull rod.
11. A method of operating a double cable pull assembly configured for use with a double pull latch assembly, comprising:
translating a pull rod between a first position and a second position through application of a force to the pull rod;
linking a selector lever rotatably attached to the pull rod to a first feature of a linkage when the pull rod is pulled a first time such that a first cable is operatively coupled to the pull rod;
linking the selector lever a second feature of the linkage when the pull rod is pulled a second time after the first time such that a second cable is operatively coupled to the pull rod; and
wherein the first cable and the second cable are configured to perform a respective action when they are actuated by the double pull latch assembly.
12. The method as in claim 11 , wherein a pull cable is operatively secured to the pull rod.
