Abstract
A hold open rod includes an inner member; an outer member configured to have the inner member slide in and out of the outer member; and a noncircular dampening member arranged on the inner member. The noncircular dampening member being configured to dampen movement of at least one of the following: the inner member and the outer member.
Claims19
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;
- and
- a noncircular dampening member arranged on the inner member, the non-circular dampening member comprising an inner surface that forms a cylindrical aperture that extends through the noncircular dampening member, the noncircular dampening member being configured to dampen movement and vibration of at least one of the following:
- the inner member and the outer member,
- wherein the inner surface that forms the cylindrical aperture is configured and sized such that the noncircular dampening member is configured to rotate about the inner member;
- wherein the noncircular dampening member comprises a three-lobed shaped member having an outer surface with three flat portions and three lobe portions;
- wherein the noncircular dampening member is configured to rotate about the inner member and change an orientation of the noncircular dampening member with respect to the inner member to change an axis of vibration of the noncircular dampening member;
- and
- wherein the noncircular dampening member is configured to provide additional intentional dynamic instability to dampen movement and vibration of at least one of the following:
- the inner member and the outer member.

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;
- and
- a noncircular dampening member arranged on the inner member, the non-circular dampening member comprising an inner surface that forms a cylindrical aperture that extends through the noncircular dampening member, the noncircular dampening member being configured to dampen movement and vibration of at least one of the following:
- the inner member and the outer member,
- wherein the inner surface that forms the cylindrical aperture is configured and sized such that the noncircular dampening member is configured to rotate about the inner member;
- wherein the noncircular dampening member comprises a three-lobed shaped member having an outer surface with three flat portions and three lobe portions;
- wherein the inner member, the outer member, and the noncircular dampening member are configured such that there is a first space between the non-circular dampening member and the outer member to allow the inner member and the noncircular dampening member to move and/or vibrate within the outer member;
- and
- wherein the inner member, the outer member, and the noncircular dampening member are configured such that there is a second space between the non-circular dampening member and the inner member to allow the inner member and the noncircular dampening member to move and/or vibrate within the outer member.

A hold open rod comprising:
- an inner member;
- an outer member configured to have the inner member located at least partially within the outer member;
- and
- a noncircular dampening member within the outer member, the non-circular dampening member comprising an inner surface that forms a cylindrical aperture that extends through the noncircular dampening member, the noncircular dampening member being configured to dampen movement and vibration of at least one of the following:
- the inner member and the outer member,
- wherein the inner surface that forms the cylindrical aperture is configured and sized such that the noncircular dampening member is configured to rotate about the inner member;
- and
- wherein the noncircular dampening member comprises a three-lobed shaped member having an outer surface with three flat portions and three lobe portions;
- wherein the inner member, the outer member, and the noncircular dampening member are configured such that there is a first space between the non-circular dampening member and the outer member to allow the inner member and the noncircular dampening member to move and/or vibrate within the outer member;
- and
- wherein the inner member, the outer member, and the noncircular dampening member are configured such that there is a second space between the non-circular dampening member and the inner member to allow the inner member and the noncircular dampening member to move and/or vibrate within the outer member.
