ABSTRACT:
A shade roller, comprised of a tube into which the motor drive is inserted into one end leaving it fully adjustable in length as it is slid in or out of the tube (Main Body), using any means of screw adjustment, shims etc. One end of the motor has a standard tip to fit into a standard shade mounting bracket, the other end is made to lock into a mounted drive block which is mounted within the main body of the roller. The locking of the motor with the drive block, can be accomplished with any means of connection that will result in the motor being unable to turn within the main body of the shade roller and at the same time leave the motor free to be adjusted in or out for the length adjustment. At the other end, a sliding shaft is inserted in much the same manner as the motor. It is fully adjustable for length as is the motor end, and is fully adjustable by similar means of shims, screw adjustments etc. as is the motor end. This shaft is not necessary to be locked into a lock block as it may turn or spin within the main body as it will. At the end of this shaft is a standard roller pin that will fit into a standard shade mounting bracket. The length adjustments, and motor replacement is designed to be accomplished fully independent and without disturbing the shade materials, and to be accomplished with the use of simple everyday tools such as screw driver or in the case of the use of shims, no tools will be required. The main body of the roller is perfectly smooth, with no bumps, ridges, grooves or indents that are damaging to the materials on the roller.
