Abstract
An air permeable sun shading fabric for provision of shade while allowing air to permeate the fabric includes a panel that is flexible and comprises a plurality of layers. The plurality of layers comprises an inner layer and an outer layer. Each of the layers has a plurality of openings. The openings are consistently sized and equally spaced, thus defining a band around each of the openings. The opening and a respective one of the bands define a unit. The openings of each of the layers are positioned in rows that are parallel. Each of the rows is offset by one half of the unit from adjacent rows. The layers are mutually coupled, such that each of the pluralities of openings is offset from the pluralities of openings positioned in adjacent layers.
Claims12
An air permeable sun shading fabric comprising:
- a panel, said panel being flexible, said panel comprising a plurality of layers, each of said plurality of layers having a top surface, said plurality of layers comprising an inner layer and an outer layer;
- each said layer having a plurality of openings, each of said openings being defined by a peripheral wall, said peripheral wall being perpendicular to said top surface of said layer, said openings being consistently sized and equally spaced defining a band around each of said openings, one of said openings and a respective one of said bands defining a unit, said openings of each said layer being positioned in rows, said rows being parallel, each said row being offset by one half of said unit from adjacent said rows;
- and
- said layers being mutually coupled such that each of said pluralities of openings is offset from said pluralities of openings positioned in adjacent said layers.
An air permeable sun shading fabric comprising:
- a panel, said panel being flexible, said panel comprising a plurality of layers, each of said plurality of layers having a top surface, said plurality of layers comprising an inner layer and an outer layer, said plurality of layers comprising at least three layers, said plurality of layers comprising said outer layer, a middle layer, and said inner layer;
- each said layer having a plurality of openings, each of said openings being defined by a peripheral wall, said peripheral wall being perpendicular to said top surface of said layer, said openings being consistently sized and equally spaced defining a band around each of said openings, one of said openings and a respective one of said bands defining a unit, said openings of each said layer being positioned in rows, said rows being parallel, each said row being offset by one half of said unit from adjacent said rows, said openings being hexagonally shaped;
- said layers being mutually coupled such that each of said pluralities of openings is offset from said pluralities of openings positioned in adjacent said layers, said openings of said middle layer being offset by one half said unit relative to said openings of said inner layer, said openings of said outer layer being offset by one half of said unit from said openings in said middle layer, said outer layer being offset relative to said middle layer perpendicularly to said middle layer being offset from said inner layer, wherein said openings positioned is said inner layer are effectively covered by said bands of the remaining of said plurality of layers, minimizing penetration of sunlight through said panel, while allowing air to permeate said panel through said openings;
- said top surfaces comprising a coating, said coating being reflective, wherein said top surface is configured for reflecting ultraviolet radiation;
- each of said plurality of layers comprising an ultraviolet absorbent compound, said coating comprising an ultraviolet absorbent compound, wherein said panel is configured for absorbing ultraviolet radiation;
- and
- said panel being configured for coupling to an umbrella frame, said panel being configured for coupling to a hexagonally shaped umbrella frame.
