Abstract

An internally coupleable joint is disclosed. The joint can include a first component and a second component configured to mate with one another in an end-to-end relationship. An axially extending protrusion of the first component can interface with a corresponding recess of the second component. In addition, the first component and the second component can each have an internal coupling feature extending at least partially about an inner circumference of the respective component. The joint can also include a securing member having external coupling features configured to engage the internal coupling features of the first and second components to prevent separation of the first and second components.

First claim

What is claimed is:

1. An internally coupleable joint, comprising:
a first component and a second component configured to be joined together in an end-to-end relationship, wherein an axially extending protrusion of the first component interfaces with a corresponding recess of the second component, the first component and the second component each having one or more non-helical internal coupling features extending at least partially about respective inner circumferences of the first and second components, respectively, wherein at least one of the one or more non-helical internal coupling features of the second component is interrupted by the recess, and operable to be aligned with at least one of the one or more non-helical internal coupling features of the first component, to traverse an interface of the first component and the second component, and wherein at least one of the one or more non-helical internal coupling features of the second component is continuous and uninterrupted by the recess; and
an internal securing member comprising first and second ends defined by a separation between the first and second ends, the internal securing member having external coupling features configured to engage the one or more non-helical internal coupling features of the first and second components,
wherein the first and second ends are configured to move radially outward to engage the external coupling features with the non-helical internal coupling features of the first and second components to prevent separation of the first and second components, and
wherein, upon securing the internal securing member to the first and second components, the one or more non-helical internal coupling features of the first and second components are engaged with the external coupling features of the internal securing member, such that an uninterrupted separation gap is defined between the first and second components.

2. The internally coupleable joint of claim 1 , further comprising a plurality of fasteners operable to couple the internal securing member to the first and second components.

3. The internally coupleable joint of claim 2 , wherein the first component, the second component, and the internal securing member include holes to receive the plurality of fasteners.

4. The internally coupleable joint of claim 3 , wherein the holes are formed in a coplanar pattern about the first and second components.

5. The internally coupleable joint of claim 1 , wherein each of the first and second components comprise a plurality of axially extending protrusions and recesses configured to mate with one another in the end-to-end relationship.

6. The internally coupleable joint of claim 1 , wherein the first component and the second component comprise a cylindrical configuration.

7. The internally coupleable joint of claim 1 , wherein the one or more non-helical internal coupling features of at least one of the first or second components comprises at least one of a ridge or a groove and the external coupling features of the internal securing member comprise at least one of a groove or a ridge to mate with the one or more non-helical internal coupling features of at least one of the first or second components.

8. The internally coupleable joint of claim 1 , wherein cross-sections of the one or more non-helical internal coupling feature of at least one of the first or second components and the external coupling features comprise mating cross-sectional thread form configurations.

9. The internally coupleable joint of claim 1 , wherein the one or more non-helical internal coupling features of the first and second components form at least one of an annular ridge and an annular groove that traverses the interface of the first component and the second component when mated.

10. A method for facilitating internal coupling of two components, comprising:
providing an internal securing member for an internally coupleable joint of a first component and a second component joined together in an end-to-end relationship, wherein an axially extending protrusion of the first component interfaces with a corresponding recess of the second component, the first component and the second component each having one or more non-helical internal coupling features extending at least partially about respective inner circumference of the respective component, wherein at least one of the one or more non-helical internal coupling features of the second component is interrupted by the recess, and operable to be aligned with at least one of the one or more non-helical internal coupling features of the first component, to traverse an interface of the first component and the second component, and wherein at least one of the one or more non-helical internal coupling features of at least one of the first and second components is uninterrupted by the axial extending protrusion and the recess; and
facilitating engagement of external coupling features of the internal securing member with the one or more non-helical internal coupling features of the first component and the second component to prevent separation of the first and second components from one another, wherein, upon securing the internal securing member to the first and second components, the one or more non-helical internal coupling features of the first and second components are engaged with the external coupling features of the internal securing member, such that an uninterrupted separation gap is defined between the first and second components.

11. The method of claim 10 , further comprising facilitating fastening the internal securing member to the first and second components.

12. The method of claim 10 , wherein the internal securing member comprises a flange configured to enhance a stiffness of the internal securing member.

13. An internally coupleable joint, comprising:
a first component and a second component configured to join together in an end-to-end relationship, the first component comprising a first axially extending protrusion configured to interface with a corresponding first recess of the second component, and at least one of the first component or the second component comprising a second axially extending protrusion that interfaces with a corresponding second recess of the other of the first or second components, the first and second axially extending protrusion and the first recess being configured differently than the second axially extending protrusion and second recess to facilitate keying of the relative orientation of the first and second components, the first component and the second component each comprising one or more non-helical internal coupling features extending at least partially about respective inner circumferences of the first and second components, respectively, wherein at least one of the one or more non-helical internal coupling features of the second component is operable to be aligned with at least one of the one or more non-helical internal coupling features of the first component, to traverse an interface of the first component and the second component; and
an internal securing member comprising external coupling features configured to engage the one or more non-helical internal coupling features of the first and second components,
wherein, upon securing the internal securing member to the first and second components, the one or more non-helical internal coupling features of the first and second components are engaged with the external coupling features of the internal securing member, such that an uninterrupted separation gap is defined between the first and second components.
