Abstract

An assembly including a first component and a second component movably coupled to the first component. The second component is formed about and coupled to at least a portion of the first component via an over-molding process.

First claim

What is claimed is:

1. An assembly comprising:
a first tubular member, of generally cylindrical shape, disposed about a central longitudinal axis and having a first end and an opposite second end, the second end including an outward extending flange; and
a second tubular member, of generally cylindrical shape, disposed about the central longitudinal axis and having a first end and an opposite second end,
wherein the first end of the second tubular member is formed about and generally permanently coupled to the outward extending flange of the first tubular member via an over-molding process, and
wherein the first tubular member is readily rotatable with respect to the second tubular member around the central longitudinal axis.

2. The assembly according to claim 1 , wherein one of the first end of the first tubular member and the second end of the second tubular member is adapted to be coupled to a conduit carrying a pressurized flow of gas from a pressure generating device and the other one of the first end of the first tubular member and the second end of the second tubular member is adapted to be coupled to a conduit coupled to a patient interface device.

3. The assembly according to claim 1 , wherein the first tubular member and the second tubular member define a sealed passage therethrough.

4. An assembly comprising:
a first tubular member having a first end and an opposite second end, the opposite second end having an outward extending flange; and
a second tubular member having a first end and an opposite second end, the first end having a second outward extending flange,
wherein the first tubular member and the second tubular member are rotatably coupled in a generally permanent manner via a coupling member formed about the outward extending flange of the first tubular member and the second outward extending flange of the second tubular member via an over-molding process.

5. The assembly according to claim 4 , wherein one of the first end of the first tubular member and the second end of the second tubular member is adapted to be coupled to a conduit carrying a pressurized flow of gas from a pressure generating device and the other one of the first end of the first tubular member and the second end of the second tubular member is adapted to be coupled to a conduit coupled to a patient interface device.

6. The assembly according to claim 5 , wherein the first tubular member and the second tubular member define a sealed passage therethrough.

7. The assembly according to claim 5 , wherein the second end of the first tubular member is spaced a predetermined distance from the first end of the second tubular member.

8. The assembly according to claim 4 , wherein the coupling member includes a recess of complimentary shape to the outward extending flange of the first tubular member and the second outward extending flange of the second tubular member.

9. The assembly according to claim 4 , wherein:
the first tubular member is disposed about a longitudinal axis;
the outward extending flange comprises:
a first surface facing along the longitudinal axis in a first direction,
a second surface facing along the longitudinal axis in a second direction opposite the first direction, and
a third surface disposed between the first surface and the second surface and facing away from the central longitudinal axis; and

the coupling member includes a recess comprising a first surface and a second surface which each are disposed about and engage a corresponding one of the first and third surfaces of the outward extending flange.

10. An assembly comprising:
a first tubular member having a first end and an opposite second end, the second end including an outward extending flange; and
a second tubular member having a first end and an opposite second end, wherein the first end of the second tubular member includes a recess correspondingly shaped to the outward extending flange, wherein the recess is formed about and coupled to the outward extending flange of the first tubular member via an over-molding process,
wherein the first tubular member is readily moveable with respect to the second tubular member.

11. The assembly according to claim 10 , wherein:
the first tubular member is disposed about a longitudinal axis;
the outward extending flange comprises:
a first surface facing along the longitudinal axis in a first direction,
a second surface facing along the longitudinal axis in a second direction opposite the first direction, and
a third surface disposed between the first surface and the second surface and facing away from the central longitudinal axis; and

the recess includes a first surface, a second surface, and a third surface which each are disposed about and engage a corresponding one of the first, second, and third surfaces of the outward extending flange.
