Skylight with displacement absorber and interlocking telescoping tubes

A tubular skylight assembly for use in a building having a roof and a ceiling, comprising:

• a collar adapted for securement to the roof, the collar defining an opening therethrough;
• a light transmitting exterior dome, the exterior dome attached to the collar, the dome configured for covering at least the opening defined through the collar;
• a top elbow, the top elbow secured to the collar and depending therefrom, the top elbow-including limiting means for limiting the top elbow from downward movement relative to the collar upon attachment of the top elbow with the collar the top elbow further including a top end and further comprising a flare disposed upon the top end, the flare adapted to abut the collar at a predetermined location of the collar about the top elbow;
• a first light tube, the first light tube secured at one end to the top elbow, the first light tube having an outside wall and an inside wall defining an opening through the first light tube, the inside wall being reflective for the transmission of light therethrough
• a second light tube, the second light tube having an outside wall and an inside wall defining an opening through the second light tube, the inside wall being reflective for the transmission of light therethrough;
• one of the first or second light tubes telescopically residing in the other;
• the first and second light tubes including interlocks located thereon configured such that engagement between the interlocks limits telescopic movement of the second light tube relative to the first light tube;
• a displacement absorber, the displacement absorber bendable, compressible, and expandable, the displacement absorber carried by one of the first or second light tubes opposite the top elbow.
