Abstract

Claims (26)

1. A line set duct system for housing and securing an HVAC line set, the line set duct system comprising:

a. a line set duct with a length for enclosing the line set and including a duct base, a line set channel connector extending along the length of the duct base of the line set duct, the line set channel connector including a center channel and first and second opposing channel grooves, each channel groove comprising a channel web and a channel lip; and

b. at least one channel clip slidably attached to the line set channel connector including:

i. a clip base;

ii. a camming leg attached to the clip base, the camming leg having:

(a) a downwardly extending portion;

(b) a perpendicularly extending portion connected to the downwardly extending portion, the perpendicularly extending portion for slidably engaging the first channel groove of the line set channel connector; and

(c) a camming surface on the perpendicularly extending portion for urging the downwardly extending portion of the camming leg away from the first opposing channel groove as the camming leg moves toward the duct base before the perpendicularly extending portion enters the first opposing channel groove; and

iii. a collar attached to the clip base for engaging a fastener that secures the line set to the line set channel of the line set duct.

2. The line set duct system of claim 1 , wherein the camming leg is attached to a side of the clip base, wherein the clip base has a first leg and a second leg attached to an opposite side of the clip base from the camming leg, and wherein the first leg and the second leg engage the second opposing channel groove.

3. The line set duct system of claim 1 , wherein the clip base has an opening to allow access to the camming leg in order to disengage the perpendicularly extending portion from the first opposing channel groove thereby disengaging the channel clip from the line set channel connector of the line set duct.

4. The line set duct system of claim 1 , wherein the channel clip has a release tab attached to a side of the clip base adjacent the camming leg and extending away from the camming leg and wherein displacing the release tab causes the perpendicularly extending portion of the camming leg to disengage from the first opposing channel groove thereby disengaging the channel clip from the line set channel connector of the line set duct.

5. The line set duct system of claim 1 , wherein the clip base has at least one downwardly extending friction element that fits within the center channel and frictionally engages the duct base.

6. A line set duct system for housing and securing an HVAC line set, the line set duct system comprising:

a. a line set duct with a length for enclosing the line set and including a duct base, a line set channel connector extending along the length of the duct base of the line set duct, the line set channel connector including a center channel and first and second opposing channel grooves, each opposing channel groove comprising a channel web and a channel lip; and

b. at least one channel clip slidably attached to the line set channel connector including:

i. a clip base;

ii. a plurality of legs attached to the clip base, each of the legs having:

(a) a downwardly extending portion;

(b) a perpendicularly extending portion connected to the downwardly extending portion, the perpendicularly extending portion for slidably engaging the first opposing channel groove or the second opposing channel groove of the line set channel connector; and

(c) a camming surface on the perpendicularly extending portion for urging the downwardly extending portion of the leg away from the opposing channel groove as the leg moves toward the duct base before the perpendicularly extending portion enters the opposing channel groove; and

iii. a collar attached to the clip base for engaging a fastener that secures the line set to the line set channel of the line set duct.

7. The line set duct system of claim 6 , wherein the plurality of legs includes four legs each attached to a corner of the clip base.

8. The line set duct system of claim 6 , wherein the clip base has openings to allow access to the legs in order to disengage the perpendicularly extending portions from the opposing channel grooves thereby disengaging the channel clip from the line set channel connector of the line set duct.

9. The line set duct system of claim 6 , wherein the clip base has at least one downwardly extending friction element that fits within the center channel and frictionally engages the duct base.

10. The line set duct system of claim 6 , wherein the plurality of legs includes two legs attached to diagonally opposite corners of the clip base and wherein the channel clip has two downwardly extending stubs attached at the corners of the clip base opposite the legs.
