Micro gap roller shade system and method of installation

A roller shade apparatus comprising:

• a roller shade tube assembly comprising:
• a tubular main housing having a first cavity divided into a proximal lumen and a distal lumen by an internal spring stop, wherein the tubular main housing comprises a distal end having a first recessed mounting cavity and a proximal end having a first plurality of interlocking fingers, wherein the distal lumen is configured to house an electric motor that is configured to drive the main housing;
• a spring inside the proximal lumen and abutting against the spring stop;
• a tubular auxiliary housing having a distal end with a second plurality of interlocking fingers slidably interlocking with the first plurality of interlocking fingers, wherein a proximal end of the auxiliary housing comprises a second recessed mounting cavity;
• an inner guide cylinder having a first end and a second end, wherein said first end is slidably coupled inside said proximal lumen of said main housing and abutting against said spring, and wherein said second end is fixedly coupled inside the auxiliary housing;
• a main side bracket, wherein the main bracket substantially fits inside said first recessed mounting cavity;
• and
• an auxiliary side bracket, wherein the auxiliary bracket substantially fits inside said second recessed mounting cavity;
• and
• a shade fabric coupled to the roller shade tube assembly.

A roller shade apparatus comprising:

• a tubular main housing having a first cavity divided into a proximal lumen and a distal lumen by an internal spring stop, wherein a proximal end of the main housing comprises a first plurality of fingers;
• an electric motor located inside said distal lumen and configured to drive the main housing;
• a spring inside the proximal lumen and abutting against the spring stop;
• a tubular auxiliary housing having a distal end with a second plurality of fingers configured as complementary to, and slidably interlocking with, the first plurality of fingers;
• an inner guide cylinder having a first end and a second end, wherein said first end is slidably coupled inside said proximal lumen of said main housing and abutting against said spring, and wherein said second end is fixedly coupled inside the auxiliary housing;
• a main side bracket configured to substantially reside inside a recessed cavity in the distal end of the main housing;
• and
• an auxiliary side bracket configured to substantially reside inside a recessed cavity in a proximal end of the auxiliary housing.
