Openable covering construction for pergolas, verandas and the like
An openable covering construction for pergolas and verandas, characterized in that said openable covering construction comprise a plurality of adjoining and partially overlapping bands longitudinally mounted on a supporting frame by a driving system allowing each said bands to be rotated about a longitudinal axis thereof parallel to a sloping side of said covering construction, said driving system driving said bands to at least two positions, a closed position, thereat said bands are partially overlapped onto one another and substantially parallel to the covering construction plane, and an opened position thereat each said band is rotated to a substantially vertical condition with respect to said covering plane, each said band comprising a section member including a contoured surface including, at a side thereof, a perpendicular side wall and, at an opposite side thereof, a channel defining curved wall, thereby a surface directly exposed to rain of said covering construction forms a water collecting and disposal of channel.
1. An openable covering construction for pergolas and verandas, characterized in that said openable covering construction comprises a plurality of adjoining and partially overlapping bands longitudinally mounted on a supporting frame by a driving system allowing each said bands to be rotated about an axis thereof parallel to a covering construction inclination axis, said driving system driving said bands to at least two positions, a closed position, thereat said bands are partially overlapped onto one another and substantially parallel to the covering construction plane, and an opened position whereat each said band is rotated to a substantially vertical condition with respect to said covering plane, each said band comprising a section member including a contoured surface including, at a side thereof, a perpendicular side wall and, at an opposite side thereof, a channel defining curved wall, whereby a surface directly exposed to rain of said covering construction forms a channel for collecting and disposal of water.
2. An openable covering construction, according to claim 1 , characterized in that each said band comprises a central element operating as a connection element for the driving system each said band is applied to.
3. An openable covering construction, according to claim 1 , characterized in that said bands are mounted parallel to an axis extending from upward to downward of said covering construction and are slanted at a minimum slanting angle of 4°.
4. An openable covering construction, according to claim 1 , characterized in that said water collecting and disposal of channel has such a cross section semicircular configuration as to collect therein and downward discharge therefrom drained water not disposed of from said concave surface.
5. An openable covering construction, according to claim 1 , characterized in that said channel of each said band has an inward curved configuration to prevent water from exiting said channel both with said covering construction in a fully closed condition and in a partially closed condition thereof.
6. An openable covering construction, according to claim 1 , characterized in that a perpendicular wall of said band operates as a nose cowling element extending to a bottom of a said channel of an adjoining band, with said covering construction arranged in a closed condition thereof.
7. An openable covering construction, according to claim 6 , characterized in that said perpendicular band wall is slightly bent so as to prevent any interferences of said bands, as said structure is opened and closed, from occurring.
8. An openable covering construction, according to claim 1 , characterized in that each said band comprises a high water collecting capability deep channel delimited by an upward and inward channel wall, and by a further channel vertical wall.
9. An openable covering construction, according to claim 1 , characterized in that each said band comprises a downward extending convexity defining a further rainwall draining main channel, causing said water to longitudinally flow in cooperation with the longitudinal inclination of said bands.
10. An openable covering construction, according to claim 1 , characterized in that said construction provides an efficient protection against rain even with said bands thereof arranged at a position opened at about 5° for allowing air to circulate therethrough.
