Rain-water deflector for circular chimney flue - has segmental bi-planar diagonal blades with radial fold mounted at common inclination to flue axis

摘要

The rain-water deflector comprises an assembly of diagonal blades (3) serving to deflect rainwater to the edges whilst permitting the unrestricted passage of smoke. The blades locate at regular angular intervals in plan, comprising two plane sectors (3a, 3b) of which the lower (3a) is at a greater inclination. The two sectors may be divided by a fold line (9) oblique and descending from the internal to the external edges. The external curved edge of the lower sector may be supported by a fixed chock (11, 13), the internal edges being flanged(6, 15) to guide rainwater to the foot.
