Window treatment mounting bracket

A motorized window treatment comprising:

• a roller tube having first and second ends, the roller tube configured to rotate about a longitudinal axis that defines a longitudinal direction;
• a flexible material that is attached to the roller tube;
• a motor drive unit located within the roller tube adjacent the first end of the roller tube, the motor drive unit configured to rotate the roller tube to adjust the flexible material between a raised position and a lowered position;
• a first mounting bracket and a second mounting bracket configured to mount the motorized window treatment to a structure, the first and second mounting brackets configured to rotatably support the roller tube at the respective first and second ends, the first and second mounting brackets each comprising an arm configured to extend from the structure, and an attachment member extending from the arm, the attachment member of each of the first and second mounting brackets defining a channel with an opening configured to slidingly receive the respective first or second end of the roller tube in a transverse direction that is perpendicular to the longitudinal axis to mount the roller tube to the first and second mounting brackets, and wherein the channel of each of the first and second mounting brackets is defined by a first flange, a second flange, and a side wall that is distal from the first and second flanges in the longitudinal direction, wherein a width of the channel in the longitudinal direction is defined by the first and second flanges and the side wall, the first and second flanges configured to secure the roller tube in position along the longitudinal axis, wherein the first mounting bracket is further configured to enclose at least a portion of an electrical wiring for powering the motor drive unit, and wherein each of the first and second mounting brackets further comprises a respective base configured to attach the respective mounting bracket to the structure, each base extending perpendicular from the respective arm at an end of the arm that is opposite the attachment member, and wherein the attachment member of each of the first and second mounting brackets comprises a drum;
• first and second sliding covers each configured to surround a respective drum, wherein the first and second sliding covers are configured to be rotated about the respective drum between an open position in which the opening of the respective channel of the respective attachment member is configured to receive the respective first or second end of the roller tube, and a closed position in which the opening of the respective channel of the respective attachment member is covered;
• a first base cover configured to mount over the base of the first mounting bracket;
• and
• a second base cover configured to mount over the base of the second mounting bracket,
• wherein the attachment member of each of the first and second mounting brackets extends a predetermined distance from the respective arm such that the flexible material is prevented from contacting the respective arm as the roller tube is rotated to adjust the flexible material between the raised position and the lowered position.
