Abstract
A joint assembly may include a first wedge ring, where the first wedge ring is arranged on an internal surface of the tubular composite rod, having a wedge-shaped radially outward geometry to form a wedge-shaped end portion. The joint assembly may include a second wedge ring, where the second wedge ring is arranged radially outward of an external surface of the tubular composite rod. The joint assembly may include a third wedge ring, where the third wedge ring is arranged between the second wedge ring and the tubular composite rod, where the third wedge ring is formed of two or more segments placed in a hoop direction. The first and the second wedge rings may be connected, for example, by thread joining.
Claims18
A joint assembly in combination with a tubular composite rod, the joint assembly comprising:
- a first wedge ring, wherein at least one end of the tubular composite rod has a wedge-shaped radially outward geometry to form a wedge-shaped end portion, wherein the first wedge ring is arranged on an internal surface of the tubular composite rod at the wedge-shaped end portion of the tubular composite rod, wherein the first wedge ring is conical and asymmetric in an axial cross-section with the wedge-shaped end portion, wherein the first wedge ring includes a first end and a second end, wherein the first end of the first wedge ring has a first diameter and the second end of the first wedge ring has a second diameter, wherein the first diameter is greater than the second diameter, wherein a slope of the first wedge ring is complementary to a rod slope of the tubular composite rod;
- a second wedge ring, wherein the second wedge ring is arranged radially outward of an external surface of the tubular composite rod at the wedge-shaped end portion of the tubular composite rod;
- and
- a third wedge ring, wherein the third wedge ring is arranged between the second wedge ring and the external surface of the tubular composite rod at the wedge-shaped end portion of the tubular composite rod, wherein the third wedge ring is formed of two or more segments placed in a hoop direction,
- wherein the second wedge ring includes a first end and a second end, wherein the first end of the second wedge ring and the first end of the first wedge ring are directly connected outside of the wedge-shaped end portion of the tubular composite rod.
An aircraft seat, the aircraft seat comprising:
- a seatback;
- a seat pan;
- and
- a base assembly couplable to a floor of an aircraft cabin via one or more floor fittings, the base assembly comprising:
- one or more tubular composite rods, wherein at least one end of the tubular composite rod has a wedge-shaped radially outward geometry to form a wedge-shaped end portion, wherein each tubular composite rod of the one or more tubular composite rods comprise:
- one or more joint assemblies, each joint assembly comprising:
- a first wedge ring, wherein the first wedge ring is arranged on an internal surface of the tubular composite rod at the wedge-shaped end portion of the tubular composite rod, wherein the first wedge ring is conical and asymmetric in an axial cross-section with the wedge-shaped end portion, wherein the first wedge ring includes a first end and a second end, wherein the first end of the first wedge ring has a first diameter and the second end of the first wedge ring has a second diameter, wherein the first diameter is greater than the second diameter, wherein a slope of the first wedge ring is complementary to a rod slope of the tubular composite rod;
- a second wedge ring, wherein the second wedge ring is arranged radially outward of an external surface of the tubular composite rod at the wedge-shaped end portion of the tubular composite rod;
- and
- a third wedge ring, wherein the third wedge ring is arranged between the second wedge ring and the external surface of the tubular composite rod at the wedge-shaped end portion of the tubular composite rod, wherein the third wedge ring is formed of two or more segments placed in a hoop direction,
- wherein the second wedge ring includes a first end and a second end, wherein the first end of the second wedge ring and the first end of the first wedge ring are directly connected outside of the wedge-shaped end portion of the tubular composite rod.
A method of manufacturing a joint assembly for a tubular composite rod comprising:
- positioning a second wedge ring axially toward a middle region of the tubular composite rod, wherein at least one end of the tubular composite rod has a wedge-shaped radially outward geometry to form a wedge-shaped end portion;
- positioning two or more segments of a third wedge ring radially to form a ring assembly in the wedge-shaped end portion of the tubular composite rod;
- translating the second wedge ring axially toward the two or more segments of the third wedge ring in the wedge-shaped end portion of the tubular composite rod;
- positioning a first wedge ring axially toward an internal surface of the tubular composite rod in the wedge-shaped end portion of the tubular composite rod, wherein the first wedge ring is conical and asymmetric in an axial cross-section with the wedge-shaped end portion, wherein a slope of the first wedge ring is complementary to a rod slope of the tubular composite rod, wherein the first wedge ring includes a first end and a second end, wherein the first end of the first wedge ring has a first diameter and the second end of the first wedge ring has a second diameter, wherein the first diameter is greater than the second diameter;
- and
- assembling the joint assembly by directly connecting the first end of the first wedge ring and the first end of the second wedge ring outside of the wedge-shaped end portion of the tubular composite rod.
