Abstract

A shade channel system and method of use to provide interchangeability of use with a zippered shade and a regular or blackout shade, together with improved efficiency of installation. A guide channel accepts a shade and is configured with a tensioning mechanism to allow the guide channel to be retained at varying depths within a base channel. The system is suitable for providing polished, uniform looks throughout a room and allowing for use of standard-sized shades by allowing the guide channel to be placed at an adjustable depth within a base channel.

First claim

What is claimed is:

1. A channel system in a mullion for a window shade, comprising:
the window shade having an edge;
a guide channel comprising a channel body having a length and a width, and a guide opening in the channel body for accepting the edge of the window shade along the length of the channel body such that the edge of the window shade is movable along the length of the channel body;
a plurality of tension mechanisms spaced at intervals along the length of the channel body and coupled to the channel body; and
the mullion having a base channel configured with a cavity having a base opening, a first inside surface, a second inside surface and a plurality of protrusions, wherein the plurality of protrusions include:
a first pair of protrusions including a first protrusion emanating from the first inside surface and an opposing first protrusion emanating from the second inside surface, wherein the first protrusion and the opposing first protrusion are opposing each other, wherein the first pair of protrusions are at a first distance from the base opening;
a second pair of protrusions including a second protrusion emanating from the first inside surface and an opposing second protrusion emanating from the second inside surface, wherein the second protrusion and the opposing second protrusion are opposing each other, wherein the second pair of protrusions are at a second distance from the base opening;
a third pair of protrusions including a third protrusion emanating from the first inside surface and an opposing third protrusion emanating from the second inside surface, wherein the third protrusion and the opposing third protrusion are opposing each other, wherein the third pair of protrusions are at a third distance from the base opening;
wherein the guide channel is configured to be inserted into the base channel, such that each of the plurality of tension mechanisms deflect to allow the guide channel to pass into the cavity of the base channel and expand to retain the guide channel in place by each of the plurality of tension mechanisms contacting only one of the first pair of protrusions at the first distance, the second pair of protrusions at the second distance or the third pair of protrusions at the third distance.

2. The channel system of claim 1 , wherein the plurality of tension mechanisms are bent spring wire.

3. The channel system of claim 1 , wherein the plurality of tension mechanisms are made of molded plastic.

4. The channel system of claim 1 , wherein the intervals along the guide channel are at even intervals.

5. The channel system of claim 1 , wherein the plurality of protrusions in the base channel allow the guide channel to be coupled to the base channel at a plurality of depths in the cavity.

6. The channel system of claim 1 , wherein the base channel includes a first base channel and a second base channel, wherein the guide channel is configured to be coupled to the first base channel, and wherein a blackout shade is receivable in the second base channel.

7. The channel system of claim 1 , wherein the contacting includes at least one of clipping into or hooking into the plurality of protrusions.
