Abstract
A hold open rod may include: an outer tube and an inner tube; a locking mechanism configured to selectively lock the inner tube with the outer tube; a locking groove in an outer surface of the inner tube; a locking dog and an outer housing covering the locking dog and at least part of the locking mechanism, the outer housing defining a cavity to contain the locking dog when the locking dog is in the outer radial position and also having an angled inner wall configured to engage the locking dog to move the locking dog to the inner radial position when the outer housing is moved to a locking position. A method of actuating a locking rod may be provided.

A lockable hold open rod comprising:
- an outer tube and an inner tube, the inner tube configured to slide in and out of the outer tube;
- a locking mechanism configured to selectively lock the inner tube with the outer tube;
- a locking groove in an outer surface of the inner tube;
- a locking dog configured to slide along the outer surface of the inner tube when the locking dog is in an outer radial position and fit in the locking groove when the locking dog in an inner radial position;
- and
- an outer housing covering the locking dog and at least part of the locking mechanism, the outer housing defining a cavity to contain the locking dog when the locking dog is in the outer radial position and also having an angled inner wall configured to engage the locking dog to move the locking dog to the inner radial position when the outer housing is moved to a locking position.
A method of actuating a locking rod comprising:
- moving a lock collar axially along an outer tube;
- sliding an inner tube with respect to an outer tube to align a locking groove with a locking dog;
- and moving the locking dog radially inward into the locking groove by sliding a surface on the lock collar against a surface on the locking dog wherein the locking dog is a reinforced plastic material.
A lockable hold open rod comprising:
- an outer tube and an inner tube, the inner tube configured to slide in and out of the outer tube;
- a locking mechanism configured to selectively lock the inner tube with the outer tube;
- a locking groove in an outer surface of the inner tube;
- a means for radially engaging configured to slide along the outer surface of the inner tube when the means for radially engaging is in an outer radial position and fit in the locking groove when the means for radially engaging is in an inner radial position;
- and
- an outer housing covering the means for radially engaging and at least part of the locking mechanism, the outer housing defining a cavity to contain the means for radially engaging when the means for radially engaging is in the outer radial position and also having an angled inner wall configured to engage the means for radically engaging to move the means for radially engaging to the inner radial position when the outer housing is moved to a locking position.
