System for securing a shade fabric to a roller tube

A system for securing a flexible shade fabric to a rotatably supported roller tube for winding receipt of the flexible shade fabric onto the tube comprising:

• an insert member including a body having opposite first and second side edges and at least one elongated slot formed in the body, the at least one slot located inwardly from the first side edge of the body to define a slot wall adjacent the first side edge having opposite ends connected to the body;
• and
• a channel including opposite first and second side walls defined by the roller, the channel dimensioned for receipt of an end portion of the flexible shade fabric, the insert member receivable within the channel to engage the end portion of the shade fabric between the roller tube and the insert member, the insert member being dimensioned such that no part of the insert member extends beyond a maximum diameter of the roller tube, the second side edge of the body and the second side wall of the channel cooperating to engage the end portion of the shade fabric therebetween,
• the slot wall defined by each of the at least one slots being outwardly deflectable with respect to the first side edge such that contact between the slot wall and the first side wall of the channel urges the body of the insert member toward the second side wall of the channel to compressively secure the end portion of the shade fabric to the roller tube between the second side edge of the body and the second side wall of the channel.

A system for securing a flexible shade fabric to a rotatably supported roller tube for winding receipt of the flexible shade fabric onto the tube comprising:

• an insert member including a body having diametrically opposite portions defining a curved outer periphery and orthogonally located diametrically opposite portions defining a substantially planar outer periphery, the body being wider between the curved outer periphery than between the substantially planar outer periphery;
• and
• a channel including opposite first and second side walls defined by the roller, the channel dimensioned for receipt of an end portion of the flexible shade fabric, the insert member receivable within the channel to engage the end portion of the shade fabric between the roller tube and the insert member,
• the insert member being pivotable about an axis to compress the end portion of the shade fabric between the second side wall of the channel and one of the curved portions to secure the shade fabric to the roller tube;
• the insert member further comprising a tool-receiving head located on the body including at least one recessed slot for receipt of a tool to facilitate pivoting of the member about the axis, the tool-receiving head comprising a disc defining a substantially circular outer periphery.

A deformable member for securing a flexible shade fabric of a shade roller to a roller tube, the roller tube including a channel having opposite first and second side walls extending longitudinally along the roller tube for receiving an end portion of a shade fabric, the deformable member comprising:

• an elongated body having opposite first and second side edges extending longitudinally along the body;
• and
• at least one elongated prong connected to the body in a recess defined in the first side edge of the body, the prong being pivotable from a first position in which the prong is located within the recess to a second position in which a terminal end portion of the prong extends from the recess to beyond the first side edge of the body, the body being receivable within the channel of the roller tube with the at least one prong in the first position,
• pivoting of the at least one prong to the second position resulting in contact between the terminal end portion of the prong and the first side wall of the channel and driving the body toward the second side wall of the channel to compress an end portion of a shade fabric between the body and the channel.
