Duct mating assembly
View Patent ↗A duct mating assembly includes first and second ducts having side surfaces connected along their edges to define an interior air space. A coupling portion is formed on one of the first or second ends of the ducts. The coupling portion of the first duct includes first and second sections joined by side sections. The first section of the first duct includes a fifth portion that extends to a sixth portion. A transition portion is positioned between the fifth and sixth portions. The transition portion steps downward and extends forward and then steps back up relative to the fifth portion for preventing air leakage between the first and second ducts. The second section of the first duct includes a first snap feature formed thereon and the fourth section of the second duct including a second snap feature formed thereon, the first and second snap features are operative to connect the second and fourth sections of the first and second ducts.
1. A duct mating assembly comprising:
a first duct having side members connected along edges of the side members defining an interior air space, the first duct extending from a first end to a second end, and
a coupling portion formed on one of the first or second ends, the coupling portion including first and second sections spaced from each other and joined by side sections;
a second duct having side members connected along edges of the side members defining an interior air space, the second duct extending from a first end to a second end, and a coupling portion formed on one of the first or second ends, the coupling portion including third and fourth sections spaced from each other and joined by side sections;
the first and second ducts operative to couple with each other, wherein the first section of the first duct includes a fifth portion extending to a sixth portion, and a transition portion positioned between the fifth and sixth portions, the transition portion stepping downward and extending forward and then stepping back up relative to the sixth portion for preventing air leakage between the first and second ducts; and
wherein the second section of the first duct includes a first snap feature formed thereon, and the fourth section of the second duct including a second snap feature formed thereon, the first and second snap features operative to connect the second and fourth sections of the first and second ducts wherein the first and third sections of the first and second ducts include embossments formed thereon, the embossment of the second duct nested with the embossment of the first duct when the first and second ducts are coupled.
2. The duct mating assembly of claim 1 wherein the embossments include slots formed thereon for allowing passage of a fastener.
3. The duct mating assembly of claim 1 wherein the first and third sections extend laterally between the side sections.
4. The duct mating assembly of claim 3 wherein the embossment is positioned midway between the side sections of the first and third sections.
5. The duct mating assembly of claim 1 wherein the embossment formed on the first section of the first duct extends below the stepped down portion of the transition portion.
6. A duct mating assembly comprising:
a first duct having side members connected along edges of the side members defining an interior air space, the first duct extending from a first end to a second end, and
a coupling portion formed on one of the first or second ends, the coupling portion including first and second sections spaced from each other and joined by side sections;
a second duct having side members connected along edges of the side members defining an interior air space, the second duct extending from a first end to a second end, and a coupling portion formed on one of the first or second ends, the coupling portion including third and fourth sections spaced from each other and joined by side sections;
the first and second ducts operative to couple with each other, wherein the first section of the first duct includes a fifth portion extending to a sixth portion, and a transition portion positioned between the fifth and sixth portions, the transition portion stepping downward and extending forward and then stepping back up relative to the sixth portion for preventing air leakage between the first and second ducts and;
wherein the second section of the first duct includes a first snap feature formed thereon, and the fourth section of the second duct including a second snap feature formed thereon, the first and second snap features operative to connect the second and fourth sections of the first and second ducts wherein the first snap feature includes an angled section extending upward to a contact section and then transitioning downward.
7. The duct mating assembly of claim 6 wherein the second snap feature includes an angled section extending upward to a contact section and then transitioning downward.
8. The duct mating assembly of claim 7 wherein the contact section of the first snap feature engages the contact section of the second snap feature when the first duct is coupled with the second duct.
