DETAILED DESCRIPTION
[0041] The disclosure will now be described with reference to the drawing figures, in which like reference numerals refer to like parts throughout. Aspects of the disclosure advantageously provide a device and process to dampen vibration in multi-rod configurations.
[0042] Prior cylindrical elements in hold open rods did not provide sufficient dampening. The result was one or more of the rods of the hold open rod would start to vibrate in response to vibration and/or acceleration associated with the implementation of application. In aspects of the disclosure, by replacing a cylindrical vibration element with a non-circular shaped vibration element, a polygonal shaped vibration element, a multi-lobe shaped vibration element and/or the like that results in improved dampening of the vibration associated with a hold open rod system. This improved dampening may reduce failures of the hold open, may reduce maintenance of the hold open rod, may allow the hold open rod to be manufactured utilizing less robust components, less costly components, and the like.
[0043] FIG. 1 illustrates a perspective view of a hold open rod according to an aspect of the disclosure.
[0044] In particular, FIG. 1 illustrates a hold open rod system 10. The hold open rod system 10 may include an inner tube 12 and an outer tube 14. The outer tube 14 may at least partially surround the inner tube 12. One or both ends of the hold open rod system 10 may include a fastener 16 for coupling the hold open rod system 10 to a particular application, for example, an aircraft door, a door frame, or the like (not shown). In further aspects, the hold open rod system 10 may include more than two tubes each telescoping into the other. However, for brevity and ease of understanding, the hold open rod system 10 will be described in the disclosure with respect to a two-rod implementation of the hold open rod system 10. Nevertheless, the various features may be implemented in a multi-rod system.
[0045] The inner tube 12 may be configured to slide into the outer tube 14 to shorten a length of the hold open rod system 10 such as when a door, hatch, or the like is shut. Then when the door or hatch is opened, the inner tube 12 may slide out of the outer tube 14. The inner tube 12 and the outer tube 14 may be made of metal such as aluminum, titanium, steel, and the like. The inner tube 12 and the outer tube 14 may be made of a synthetic material, composite materials such as carbon fiber, or any other suitable materials. The inner tube 12 and the outer tube 14 may be made of the same material; or the inner tube 12 and the outer tube 14 may be made of different materials. The inner tube 12 and the outer tube 14 may have a cylindrical cross-section, a square cross-section, a hexagonal cross-section, a polygonal cross-section, or the like.
[0046] In some aspects, locking the inner tube 12 with respect to the outer tube 14 may be beneficial. In these aspects, the inner tube 12 may be locked with respect to the outer tube 14 utilizing a locking mechanism 18. The locking mechanism 18 may be internal to the hold open rod system 10, may be external to the hold the hold open rod system 10, may be a combination thereof, or the like. However, in other aspects the hold open rod system 10 may not utilize any form of locking mechanism.

As further shown in FIG. 6, the location of the space 102 between the dampening member 100 and the outer tube 14 is illustrated. As further shown in FIG. 6, the space 104 allows for the dampening member 100 to rotate about the inner tube 12 as illustrated by arrow 116. In particular, the configuration of the dampening member 100 to rotate about the inner tube 12 may provide additional intentional dynamic instability that may help dampen vibration.
[0061] FIG. 7 illustrates another cross-sectional view of the hold open rod according to FIG. 1 with a dampening member in a first orientation; and FIG. 8 illustrates another cross-sectional view of the hold open rod according to FIG. 7.

[0063] Additionally, as shown in FIG. 6, there is a space 104 between the dampening member 100 and the inner tube 12. The dampening member 100 together with the space 104 may be configured to rotate about the end of the inner tube 12 at the tube stop 24. This ability to rotate provides additional intentional dynamic instability.
[0064] FIG. 9 illustrates another cross-sectional view of the hold open rod according to FIG. 1 with a dampening member in a second orientation; and FIG. 10 illustrates another cross-sectional view of the hold open rod according to FIG. 9.
[0065] As illustrated in FIG. 9 and FIG. 10, the dampening member 100 has rotated such that the space 102 is now located at a different position. The space 102 between the dampening member 100 and the outer tube 14 may allow the inner tube 12 and the dampening member 100 to move and/or vibrate in the direction of arrow 124. FIG. 9 shows the dampening member 100 in the inner tube 12 in a lower left position; and FIG. 10 shows the dampening member 100 and the inner tube 12 in an upper right position.
[0066] During an operational implementation of the hold open rod system 10, the dampening member 100 may be in a first orientation as illustrated in FIG. 7 and FIG. 8. Accordingly, the inner tube 12 and dampening member 100 may vibrate in a direction of arrow 122. As illustrated in FIG. 7, the dampening member 100 has two of the lobe portions 112 contacting an inner surface of the outer tube 14. The dampening member may vibrate upwardly in the direction of arrow 122 such that another one of the lobe portions 112 contacts another portion of an inner surface of the outer tube 14 as illustrated in FIG. 8.

[0067] Subsequently, the dampening member 100 may rotate in the direction of arrow 116 (or a direction opposite the arrow 116) as illustrated in FIG. 9 and FIG. 10 to be in a second orientation. In this regard, the dampening member 100 may have an infinite number of orientations defined as being 360 around the inner tube 12. Rotation of the dampening member 100 may be caused by the vibration experienced by the hold open rod system 10, In other words, as the hold open rod system 10 vibrates, the dampening member 100 may rotate about the inner tube 12.
[0068] As illustrated in FIG. 9, the dampening member 100 has two of the lobe portions 112 contacting an inner surface of the outer tube 14 (along the bottom and side thereof). The dampening member 100 may vibrate upwardly and to the right in the direction of arrow 124 such that another one of the lobe portions 112 contacts another portion of an inner surface of the outer tube 14 as illustrated in FIG. 10. The lobe portions 112 of the dampening member 100 may dampen the vibrational movement of the inner tube 12.
[0069] As described herein, the rotational movement of the dampening member 100 as illustrated in FIGS. 7-10 changes the axis of vibration of the dampening member 100 as well as the inner tube 12, This rotational movement of the dampening member 100 as well as changing the axis of vibration provides instability to the system that results in increased dampening. This increased dampening is in an unexpected result. Moreover, this dampening is markedly much better, much greater, then prior art circular implementations of dampening members. This increased dampening may reduce failures of the hold open rod system 10, may reduce maintenance of the hold open rod system 10, may allow the hold open rod system 10 to be manufactured utilizing less robust components, less costly components, and the like.
