Abstract

A coupler for joining conduit can include a body defining an internal body passage that includes a first open end to receive a first conduit in a first axial insertion direction and a second open end to receive a second conduit in a second axial insertion direction. The body can include a tongue extending from a first axial end of the body in a tongue direction, opposite the first axial insertion direction, to provide a support surface that extends axially away from the first open end of the internal body passage in the tongue direction. The tongue can include a landing surface aligned with a bottom portion of the support surface and wings extending upwardly and laterally outwardly from the landing surface. The tongue can extend around less than a full perimeter of the first open end and the wings extend laterally wider than the first open end.

First claim

We claim:

1 . A coupler for joining conduit, the coupler comprising:
a body defining an internal body passage that includes a first open end to receive a first conduit in a first axial insertion direction and a second open end to receive a second conduit in a second axial insertion direction opposite the first axial insertion direction; and a tongue extending from a first axial end of the body in a tongue direction, opposite the first axial insertion direction, to provide a support surface that extends axially away from the first open end of the internal body passage in the tongue direction, including a landing surface at a bottom portion of the support surface and wings extending upwardly and laterally outwardly from the landing surface, the tongue extending around less than a full perimeter of the first open end and the wings extending laterally wider than the first open end.

2 . The coupler of claim 1 , wherein the tongue extends from the first open end, by at least 10% of an axial length of the body.

3 . The coupler of claim 1 , wherein the wings include a first wing and a second wing that extend symmetrically relative to one another.

4 . The coupler of claim 3 , wherein the first wing and the second wing extend from the landing surface at an oblique angle relative to a tangent line at a bottom point on the landing surface.

5 . The coupler of claim 4 , wherein the first and second wings are planar between free ends thereof and the landing surface.

6 . The coupler of claim 1 , wherein a distance between a free end of a first wing of the wings and a free end of a second wing of the wings is greater than a diameter of the first open end.

7 . The coupler of claim 1 , wherein an inspection opening extends radially through an exterior wall that defines the internal body passage to provide visual access to at least one of the first and second conduit within the internal body passage.

8 . The coupler of claim 1 , further comprising a tab extending from the first open end in the tongue direction, on an opposite side of the first open end from the landing surface.

9 . The coupler of claim 8 , wherein the landing surface extends farther in the tongue direction than the tab.

10 . The coupler of claim 1 , wherein the landing surface extends co-radially with at least a bottom portion of the internal body passage at the first open end.

11 . The coupler of claim 10 , wherein the wings taper inwardly, along the insertion direction, from distal ends thereof to connections between the wings and the first axial end of the body.

12 . The coupler of claim 11 , wherein the first axial end of the body includes a tapered entry extending in the tongue direction from the first open end;
wherein the wings include top free edges; and wherein the top free edges taper inwardly to connect to a distal end of the tapered entry.

13 . The coupler of claim 1 , wherein the landing surface is integral with the body.

14 . The coupler of claim 1 , wherein the landing surface extends integrally from a sleeve of an adapter that defines an internal sleeve passage; and
wherein the body is received into the internal sleeve passage to secure the landing surface to the body.

15 . A method of connecting a first conduit to a second conduit, the method comprising:
connecting the first conduit to a body of a coupler by extending the first conduit into an internal body passage that is defined by the body, with the coupler inserted in a first axial insertion direction into a first open end of the internal body passage at a first axial end of the body, the body further including a second open end of the internal body passage at a second axial end of the body opposite the first axial end, the second open end defining a second axial insertion direction opposite the first axial insertion direction; and connecting the second conduit to the coupler by:
resting the second conduit on a landing surface of the coupler that is included on a tongue that extends from the second axial end of the body in a tongue direction that is opposite the second axial insertion direction; and
moving the second conduit from the landing surface in the second axial insertion direction, to extend the second conduit into the internal body passage of the coupler at the second open end,
the second conduit being guided to one or more of the landing surface or the second open end by wings of the coupler that extend upwardly from the landing surface and laterally outwardly from the landing surface to be laterally wider than the second open end.

16 . The method of claim 15 , wherein the second conduit is guided from the landing surface to the second open end by a tab extending from the second open end in the tongue direction, on an opposite side of the second open end from the landing surface.

17 . The method of claim 15 , wherein a width between the wings tapers from a top to bottom perspective, so that one or more of the wings guide the second conduit from a laterally offset alignment relative to the second open end toward a centered alignment relative to the second open end as the conduit is lowered onto the one or more of the wings from the laterally offset alignment.

18 . The method of claim 17 , wherein the width between wings tapers from a perspective along the second insertion direction, so that one or more of the wings guide the second conduit from the laterally offset alignment toward the centered alignment as the conduit is moved in the second insertion direction from the laterally offset alignment.

19 . The method of claim 15 , further comprising:
connecting the landing surface to the body by inserting the body into an internal sleeve of an adapter that includes the landing surface.

20 A. coupler for joining conduit, the coupler comprising:
a body that includes an exterior wall surrounding an internal body passage, the internal body passage including a first open end to receive a first conduit in a first axial insertion direction and a second open end to receive a second conduit in a second axial insertion direction;
a tapered entry extending from the first open end; and
a cylindrical insertion passage extending from the tapered entry, opposite the first open end, with a greater internal width than the first open end;
the tapered entry extending from the first open end, in a direction opposite the first axial insertion direction; and
the insertion passage extending from the tapered entry, in a direction opposite the first axial insertion direction.
