DETAILED DESCRIPTION

[0016] FIG. 1 is a perspective view of extendable hose coupler 100 including outer tube 110 and inner tube 200. In FIG. 1, inner tube 200 is shown separated from outer tube 110. A first connector is shown having a first end positioned over a first end of outer tube 110. First connector 220 has a reduced inner diameter second end into which a first angled hose connector 130 is positioned. The second end of the first angled hose connector 130 is adapted to be secured to a first hose attachment point. A first end of a second angled hose connector 120 is positioned over a second end of outer tube 110, and a second end of the second angled hose connector 120 is adapted to be secured to a second hose attachment point.

[0017] Inner tube 200 is shown having a second end of first connector 220 positioned over the first end of inner tube 200. A second connector 210 is positioned over a second end of inner tube 200. Second connector 210 is adapted to receive an angled hose connector that will be attached to the first hose attachment point. A third

[0018] FIG. 2 is a perspective view of extendable hose coupler 100 shown in FIG. 1 with inner tube 200 positioned within outer tube 110. The first connector 220 has an inner diameter that is greater than an outer diameter of outer tube 110 and first connector 220 is positioned over the first end of outer tube 110. First connector 220 includes a first tightening mechanism that is used to tightly secure the first connector 220 to the first end of the outer tube 110. First connector 220 is somewhat flexible to allow the first tightening mechanism to squeeze the first end of first connector 110 onto the first end of the outer tube 110. The inner tube 200 is slidably positioned within outer tube 110. Thus, inner tube 200 has an outer diameter that is less than an inner diameter of outer tube 110. The inner tube 200 may be positioned within the outer tube 100 at a desired distance to provide a desired length of the extendable hose coupler 100. Therefore, the adjustable hose coupler 100 advantageously provides for a variable length extendable hose coupler that can be adjusted in length to accommodate varying distances between hose attachment points within an automotive vehicle, or other apparatuses that include hose attachment points to be connected with a hose coupler.

[0019] Once the inner tube 200 is located in a desired position within the outer tube 110, a second tightening mechanism on the second end of first connector 220 is tightened to tightly secure the second end of first connector 220 onto the outer diameter of inner tube 200 to maintain a desired length of the extendable hose connector 100.

[0020] A second connector 210 has a first end that is positioned over a second end of the inner tube 200 and a first tightening mechanism is tightened to tightly secure the second connector 210 to the second end of inner tube 200. A first end of an angled hose connector 130 is positioned within a second end of second connector 210 and a second tightening mechanism is tightened to secure the first end of the first hose connector to the second end of the second connector. A second end of angled hose connector 130 is adapted to be secured to a first hose attachment point.

[0021] A second angled hose connector 120 has a first end positioned over a second end of outer tube 110. A second end of angled hose connector 120 has a second end that is adapted to be secured to a second hose attachment point. Second angled hose connector 120 could be secured to the second end of the outer tube 110 using a rubber O-ring positioned between an inner surface of the first end of the second angled hose connector 120 and the second end of the outer tube 110. First and second angled hose connectors 130 and 120 are shown with a 90 degree angle between the first and second ends thereof. However, different angles between the first and second connectors may also be used, such as angles between 45-135 degrees, depending on the position of the first and second hose attachment points.

[0022] In FIG. 2, the first and second tightening mechanisms on the first connector 220 and second connector 210 are shown as a metal strap, however other tightening mechanisms may also be used including a set screw or other devices for squeezing the ends of the first and second connectors onto the inner tube 200 and outer tube 110 to tightly secure the first connector 220 and second connector 210 onto the inner and outer tubes 110 and 200. The first connector 220 and second connector 210 may be made of rubber, or other flexible materials, to allow the first and second connectors 220 and 210 to be tightly secured to the inner and/or outer tubes 200 and 110. A third connector 230 may be used to secure second hose connector 120 to the second end of the outer tube.
