Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention description below refers to the accompanying drawings, of which:

(2) FIG. 1 is an exploded view of the toe kick ducting system.

(3) FIG. 2A is an isometric, exploded view of the ducting system shown in FIG. 1.

(4) FIG. 2B depicts the ducting system of FIG. 2A with a cabinet above.

DETAILED DESCRIPTION

(5) Referring to FIG. 1, the under cabinet supply cover 1 is 12″×4″×3¾″ with four (4) flanges 7, one on the left, one on the right, one on the top, and one on the bottom. The front and back flanges start at 1″ on either end and curve slightly like a bell curve, bringing the radius curve to 1¾″ in the middle. These flanges 7 are 12″ long. On the front side of the supply cover is an oval cut out for an oval collar that is dimensioned to be connected to one of the sides of the cabinet supply cover 1, i.e., one of the sides described above as being 3¾″ or 4″.

(6) One end of a first oval collar 2 is connected to the under cabinet supply cover 1. This allows a flex duct hose 3 to be connected to the other end of the first oval collar. The other end of flex duct hose 3, which is 24″ long, is attached to a second oval collar 2. Two metal band clamps 5 are designed to tightly attach the flex duct hose 3 to both the first and second oval collars 2.

(7) Second oval collar 2 is attached to a toe kick backer plate 4. The toe kick backer plate 4 is attached to a cabinet base at the toe kick. The toe kick backer plate 4 has two tabs cut into the face of the plate, one on the left and one on the right. These tabs are simply bent onto the cabinet toe kick and secured with 2 screws.

(8) There are different ways to seal the under cabinet supply cover 1 over the supply boot that is under the cabinet, including but not limited to a gasket, caulking, duct sealer, and/or glue adhesive. The under cabinet supply cover may be nailed or screwed to the floor.

(9) Oval collar 2 has a tamping flange 6 to secure it to both the under cabinet supply cover 1 and the toe kick backer plate 4, this type of flange being capable of forming a sliding connection between the oval collar and the cover 1 or plate 4. Another way this may be done is by using dovetails or by creating a flange that can be screwed to both the under cabinet supply cover 1 and the toe kick backer plate 4.

(10) Flexible duct hose 3 is made of foil. There are other flexible duct products, some more rigid, some are made of plastic. Flexible duct hose 3 is attached to oval collar 2 with metal straps 5. Hose clamps, tie bands, plastic ties, wire or tape may also be used.

(11) The toe kick backer plate 4 is made of sheet metal with two finger tabs that are simply bent over the toe kick, then screwed into place. Toe kick backer plate 4 may also be attached simply by screwing straight through the toe kick into the toe kick backer plate 4.

(12) The foregoing has been a detailed description of illustrative embodiments of the invention. Various modifications and additions can be made without departing from the spirit and scope if this invention. Each of the various embodiments described above may be combined with other described embodiments in order to provide multiple features. Furthermore, while the foregoing describes a number of separate embodiments of the apparatus and method of the present invention, what has been described herein is merely illustrative of the application of the principles of the present invention. Accordingly, this description is meant to be taken only by way of example, and not to otherwise limit the scope of this invention.
