System for securing shade material to a roller shade

A channel for receiving a retaining member to secure shade material to a roller shade, the channel comprising:

• a first and second retaining lip sections that define an opening into the interior cavity of the channel;
• a first bottom wall section opposite the first retaining lip and aligned along a first plane;
• a second bottom wall section opposite the second retaining lip and aligned along a second plane offset from the first plane;
• wherein the second retaining lip comprises an outer lip wall that tapers towards the interior cavity and is aligned along the same first plane as the first bottom wall section;
• wherein a top end of the retaining member is inserted through the opening and into the interior cavity along the first plane under the first retaining lip and over the outer lip wall and the first bottom wall section, and wherein the retaining member rotated into place from being aligned with the first plane to being aligned with the second plane such that a bottom end of the retaining member is positioned between the second retaining lip and the second bottom wall section, wherein the retaining member secures a portion of the shade material within the interior cavity of the channel.

A method for securing shade material to a roller shade comprising a channel having an opening between a first retaining lip and a second retaining lip, an interior cavity, a first bottom wall section opposite the first retaining lip and aligned along a first plane, and a second bottom wall section opposite the second retaining lip and aligned along a second plane offset from the first plane, wherein the second retaining lip comprises an outer lip wall that tapers towards the interior cavity and is aligned along the same first plane as the first bottom wall section, the method comprising the steps of:

• wrapping a top end of a retaining member with the shade material;
• inserting the top end of the retaining member through the opening into the interior cavity along the first plane under the first retaining lip and over the outer lip wall and the first bottom wall section;
• and
• rotating the retaining member from being aligned with the first plane to being aligned with the second plane, wherein the bottom end of the retaining member is slid along the second plane until being positioned between the second retaining lip and the second bottom wall section.

A roller shade comprising:

• a shade material comprising a bottom end;
• a retaining member;
• and
• a hem bar comprising an outer surface and a channel recessed in the outer surface, wherein the channel comprises:
• an opening in the outer surface of the hem bar that extends between a first retaining lip and a second retaining lip and provides access into an interior cavity of the channel;
• a bottom wall comprising a first bottom wall section opposite the first retaining lip and aligned along a first plane, and a second bottom wall section opposite the second retaining lip and aligned along a second plane offset from the first plane;
• and
• an outer lip wall that extends from the outer surface of the hem bar to a tip of the second retaining lip and tapers towards the interior cavity, wherein the outer lip wall is aligned along the same first plane as the first bottom wall section;
• wherein the retaining member secures the bottom end of the shade material within the interior cavity of the channel in the hem bar.
