Duct replacement device and method of use
View Patent ↗A duct replacement device and method of use provides a duct sleeve flex connector, in three different versions, each with a flat, rigid metal bar with thin, metal bracing strips and a female-treaded pole hinge. After cutting loose the old duct from under the register box, an HVAC technician enters the attic and threads the device on a telescoping pole, depositing the device near the open register box. The technician then climbs a ladder under the register box, grabs and adjusts the device with the flat, rigid metal bar into position, then attaches it with the thin, metal bracing strips.
1. A duct sleeve flex connector for connecting a new duct to an existing register box, consisting of: a body with a duct end and a register box end, with an outer surface and an inner surface, a flat, rigid metal bar, two or more metal bracing strips, and a female-threaded pole hinge, where the flat, rigid metal bar has two ends, where a first end is attached to a first location of the inner surface of the body, and a second end is attached to a second location of the inner surface of the body, where the first location is 180 degrees opposite the second location, where each end of the flat, rigid metal bar is attached to a metal bracing strip, where the metal bracing strip can rotate 360 degrees, where the female-threaded pole hinge mates with a male-threaded end of a telescoping pole.
2. The duct sleeve flex connector of claim 1 , where the duct sleeve flex connector is a cylinder with a 90-degree bend in it.
3. The duct sleeve flex connector of claim 2 , where the duct sleeve flex connector is a rectangular box with a round outlet exit.
4. The duct sleeve flex connector of claim 1 , where the duct sleeve flex connector is a cylinder.
