Abstract
A hold open rod may include: an inner member; an outer member configured to have the inner member slide in and out of the outer member; a locking mechanism including a portion attached to the outer member and a portion attached to the inner member; a locking plug configured to move axially along an axis of the inner, outer members; a locking dog configured to move radially between a locking position and an unlocking position and a release cable operatively connected to the locking plug and configured to move the locking plug to the unlocking position. A method of actuating a lock mechanism on a hold open rod may also be provided.
Claims20
A hold open rod comprising:
- an inner member;
- an outer member configured to have the inner member slide in and out of the outer member;
- a locking mechanism including a portion attached to the outer member and a portion attached to the inner member wherein the two portions are selectively locked to each other thereby locking the inner and outer members with respect to each other;
- a locking plug configured to move axially along an axis of the inner, outer members and the locking mechanism to a locking and unlocking position;
- a locking dog configured to move radially between a locking position and an unlocking position as a result of a camming action with the locking plug as the locking plug moves axially;
- and
- a release cable operatively connected to the locking plug and configured to move the locking plug to the unlocking position when the cable is placed in tension,
- wherein the release cable extends outside the hold open rod.
A method of actuating a lock mechanism on a hold open rod comprising:
- pulling on a cable and thereby:
- compressing a spring;
- moving a locking plug along an axis of the hold open rod;
- camming a locking dog along a slanted surface of the locking plug;
- moving the locking dog radially inward toward the axis;
- and
- moving the locking dog out of a locking slot.
A hold open rod comprising:
- an inner member;
- an outer member configured to have the inner member slide in and out of the outer member;
- a means for locking the inner member to the outer member;
- and
- a release cable operatively connected to the means for locking and configured to move the means for locking an unlocking position when the cable is placed in tension by moving a locking dog in the means for locking out of a locking slot by sliding the locking dog along a camming surface,
- wherein the release cable extends outside the hold open rod.
