Patent

CA 2297388

The roof drain cover of the present invention comprises a dome-shaped strainer adapted to sit over a roof drain pipe, a bolt going through the strainer at the centre thereof, protruding from the same to downwardly extend within the pipe and having a bolt head accessible from above the strainer and abutting the same, an anchor and a disc-like stop. The anchor includes a nut screwed on the bolt, a pair of wings pivoted on the nut and foldable along the bolt and towards the strainer against the bias of a spring carried by the nut. The tips of the wings are adapted to frictionally engage the inner face of the pipe under the bias of the spring to prevent rotation of the nut when the bolt is screwed within the strainer. The disc-like stop is secured to the bolt above the nut and engages the wings to cause firm anchoring engagement of the wing tips with the pipe when the stop approaches the nut during screwing of the bolt.
