Abstract

A hose/clamp assembly is provided that has a hose, a hose clamp, and a retaining device. The hose clamp is openable and closable. The retaining device has an arm, a clamp retainer attached to a first end of the arm, and a hose clip attached to a second end of the arm. The retaining device is removably attached to the hose and the hose clamp. The retaining device secures the hose clamp to the hose when the hose clamp is in a expanded, open configuration.

Claims

1. A hose/clamp assembly comprising:

a hose;

a hose clamp placed around the hose, the hose clamp being openable and closable; and

a retaining device having an arm, a clamp retainer attached to a first end of the arm, and a hose clip attached to a second end of the arm;

wherein the clamp retainer is removably attached to the hose clamp, and the hose clip is removably attached to the hose to secure the hose clamp to the hose; and

wherein the clamp retainer and the hose clip each have a semi-circular shape defining an opening, wherein the opening of the clamp retainer forms a tight snap fit on the hose clamp when the hose clamp is in an expanded, open configuration, and wherein the opening of the hose clip forms a tight snap fit on the hose at a location spaced apart from the hose clamp.

2. The hose/clamp assembly of claim 1, wherein the clamp retainer is removably attached to the hose clamp when the hose clamp is in an expanded, open configuration.

3. The hose/clamp assembly of claim 1, wherein the arm is sized so as to provide a longitudinal spacing between the clamp retainer and the hose clip of at least approximately one centimeter.

4. The hose/clamp assembly of claim 1, wherein the clamp retainer further comprises a clamp locator protruding from an arcuate inner surface of the clamp retainer to help locate and retain the hose clamp in the clamp retainer.

6. The hose/clamp assembly of claim 1, wherein the retaining device further comprises at least one raised feature disposed on an arcuate inner surface of the hose clip to engage the outer surface of the hose to help to prevent rotation of the retaining device about the hose.

7. The hose/clamp assembly of claim 6, wherein the raised feature comprises a plurality of longitudinal ribs spaced apart on the arcuate inner surface of the hose clip.

8. The hose/clamp assembly of claim 6, wherein the raised feature comprises a first and a second elongated tooth protruding from the arcuate inner surface of the hose clip, and located in a circumferentially offset position to provide a dynamic gripping force.

9. The hose/clamp assembly of claim 6, wherein the raised feature comprises at least one springable contact protruding from the arcuate inner surface of the hose clip, and the springable contact exerts an approximately constant force on the hose.

10. The hose/clamp assembly of claim 1, wherein the retaining device is made of a polymer.

11. The hose/clamp assembly of claim 10, wherein the retaining device is made of a nylon polymer.

12. The hose/clamp assembly of claim 1, wherein the retaining device is made of a metal.

13. The hose/clamp assembly of claim 1, wherein the clamp retainer further comprises a retaining lip extending radially inwardly beyond an arcuate inner surface of the clamp retainer to locate radially the clamp retainer on the hose.

27. The hose/clamp assembly of claim 1, wherein the hose clip is spaced apart from the clamp retainer to permit the insertion of a removal tool to remove the retaining device from the hose and hose clamp.

28. The hose/clamp assembly of claim 1, wherein the hose clip is spaced apart from the clamp retainer to place the hose clip onto the hose at a location removed from the portion of the hose having the hose clamp that is to be assembled onto a stem component of a fluid-carrying system.

33. The hose/clamp assembly of claim 7, wherein the raised feature further comprises a first and a second elongated tooth protruding from the arcuate inner surface of the hose clip, and located in a circumferentially offset position to provide a dynamic gripping force.

34. The hose/clamp assembly of claim 9, wherein the springable contact includes a pair of contact fingers cantilevered from a contact base that is attached to the arcuate inner surface.

5. (canceled)

14-20. -20. (canceled)

21. A retaining device for holding a hose clamp on a hose, the retaining device comprising an arm, a clamp retainer attached to a first end of the arm, and a hose clip attached to a second end of the arm, wherein the clamp retainer is capable of being removably attached to a hose clamp and the hose clip is capable of being removably attached to a hose to secure the hose clamp to the hose;

wherein the clamp retainer and the hose clip each have a semi-circular shape defining an opening, wherein the opening of the clamp retainer is capable of forming a tight snap-fit on the hose clamp when the hose clamp is in an expanded, open configuration, and wherein the opening of the hose clip is capable of forming a tight snap-fit on the hose at a location spaced apart from the hose clamp;

wherein the retaining device further comprises at least one raised feature disposed on an arcuate inner surface of the hose clip to engage the outer surface of the hose to help to prevent rotation of the retaining device about the hose; and

wherein the raised feature comprises a first and a second elongated tooth protruding from the arcuate inner surface of the hose clip, and located in a circumferentially offset position to provide a dynamic gripping force.

22. A retaining device for holding a hose clamp on a hose, the retaining device comprising an arm, a clamp retainer attached to a first end of the arm, and a hose clip attached to a second end of the arm, wherein the clamp retainer is capable of being removably attached to a hose clamp and the hose clip is capable of being removably attached to a hose to secure the hose clamp to the hose;

wherein the clamp retainer and the hose clip each have a semi-circular shape defining an opening, wherein the opening of the clamp retainer is capable of forming a tight snap-fit on the hose clamp when the hose clamp is in an expanded, open configuration, and wherein the opening of the hose clip is capable of forming a tight snap-fit on the hose at a location spaced apart from the hose clamp;

wherein the retaining device further comprises at least one raised feature disposed on an arcuate inner surface of the hose clip to engage the outer surface of the hose to help to prevent rotation of the retaining device about the hose; and

wherein the raised feature comprises at least one springable contact protruding from the arcuate inner surface of the hose clip, and the springable contact exerts an approximately constant force on the hose.

29-30. -30. (canceled)

31. A method for installation of a hose clamp of a hose/clamp assembly comprising:

(a) placing a hose/clamp assembly onto a stem component of a fluid-carrying system, the hose clamp assembly comprising;

a hose;

a hose clamp placed around the hose, the hose clamp being openable and closable; and

a retaining device having an arm, a clamp retainer attached to a first end of the arm, and a hose clip attached to a second end of the arm;

wherein the clamp retainer is removably attached to the hose clamp, and the hose clip is removably attached to the hose to secure the hose clamp to the hose; and

wherein the clamp retainer and the hose clip each have a semi-circular shape defining an opening, wherein the opening of the clamp retainer forms a tight snap fit on the hose clamp when the hose clamp is in an expanded, open configuration, and wherein the opening of the hose clip forms a tight snap fit on the hose at a location spaced apart from the hose clamp;

(b) converting the hose clamp from its open configuration to its closed configuration; and

(c) removing the retaining device from the hose clamp and hose.
