Abstract

A roller blind is disclosed which provides horizontal slats for directional shading, enabling the application of a screen fabric which allows a greater portion of visible light to pass therethrough. The disclosed slatted roller blind is free from the usage of ladder cords and is simplistic in design. The disclosed slatted roller blind maintains a compact formation of a roller shade when retracted and has greater resistance to skewing along the longitudinal axis of the roller while being retracted. Furthermore, the disclosed slatted roller blind design is capable of being utilized as an outdoor or indoor blind.

First claim

1 - 33 . (canceled)

34 . A roller blind, comprising
a screen configured to be wound and unwound between a retracted state and an extended. state, said screen including a screen material extending in a widthwise direction between opposed side edges and in a lengthwise direction between top and bottom edges, said screen material having a mesh configuration defining an open area of said screen for allowing the passage of light therethrough, the open area corresponding to greater than 10% of a total area of said screen; and a plurality of slats, each of said plurality of slats including a first longitudinal edge coupled to said screen and a second longitudinal edge opposite said first longitudinal edge, each of said plurality of slats defining a curved profile between said first and second longitudinal edges, wherein, when said screen is in the extended state, said plurality of slats are configured to provide directional shading by blocking at least a portion of the light passing through said screen.

35 . The roller blind of claim 34 , wherein the open area ranges from 40% to 50% of the total area of said screen.

36 . The roller blind of claim 34 , wherein:
the open area of said screen is defined by a plurality of spaced apart apertures; and said plurality of spaced apart apertures are evenly spaced apart from one another such that the open area is distributed equally across said screen in both the widthwise direction and the lengthwise direction.

37 . The roller blind of claim 34 , wherein the open area provides a view through said screen.

38 . The roller blind of claim 34 , wherein each of said plurality of slats is supported on said screen in a cantilevered arrangement at said first longitudinal edge when said screen is in the extended state such that said second longitudinal edge corresponds to a free unsupported end of each of said plurality of slats.

39 . The roller blind of claim 34 , wherein said first longitudinal edge is coupled to said screen along a width of said screen defined in the widthwise direction.

40 . The roller blind of claim 34 , wherein, when said screen is unwound to the extended state, said second longitudinal edge of each of said plurality of slats is spaced apart from said screen.

41 . The roller blind of claim 34 , Wherein each of said plurality of slats defines a curved profile between said first and second longitudinal edges.

42 . The roller blind of claim 41 , wherein:
said screen forms a spiral curve when wound to the retracted state; and the curved profile of each of said plurality of slats defines a set curvature that matches a segment of the spiral curve across which each of said plurality of slats extends when said screen is in the retracted state.

43 . The roller blind of claim 41 , wherein a radius of curvature of the curved profile varies between adjacent slats of said plurality of slats.

44 . The roller blind of claim 43 , wherein;
said plurality of slats are spaced apart along said screen in the lengthwise direction between said top and bottom ends; and wherein the radius of curvature is progressively increased between said adjacent slats in the lengthwise direction such that slats positioned closer to said bottom end define a larger radius of curvature than slats positioned closer to said top end.

45 . The roller blind of claim 41 , wherein a radius of curvature of the curved profile varies between said first longitudinal end and said second longitudinal end of each of said plurality of slats.

46 . The roller blind of claim 34 , wherein said plurality of slats are spaced apart from one another along said screen in the lengthwise direction.

47 . The roller blind of claim 46 , wherein the spacing defined between adjacent slats of said plurality of slats varies between said top and bottom ends of said screen.

48 . The roller blind of claim 46 , wherein the spacing progressively increases or decreases between said adjacent slats from said top end of said screen to said bottom end of said screen.

49 . A roller blind, comprising:
a screen configured to be wound and unwound between a. retracted state and an extended state, said screen including a screen material extending in a widthwise direction between opposed side edges and in a lengthwise direction between top and bottom edges, said screen material having a mesh configuration such that a plurality of spaced apart apertures are defined. within said screen between said opposed side edges and between said top and bottom edges, said plurality of spaced apart apertures defining an open area of said screen for allowing the passage of light therethrough; and a plurality of slats, each of said plurality of slats including a first longitudinal edge coupled to said screen and a second longitudinal edge opposite said first longitudinal edge, each of said plurality of slats being supported on said screen in a cantilevered arrangement at said first longitudinal edge when said screen is in the extended state such that said second longitudinal edge corresponds to a free unsupported end of each of said plurality of slats.

50 . The roller blind of claim 49 , wherein the open area corresponds to greater than 10% of a total area of said screen.

51 . The roller blind of claim 50 , wherein the open area ranges from 40% to 50% of the total area of said screen.

52 . The roller blind of claim 49 , wherein said plurality of spaced apart apertures are evenly spaced apart from one another such that the open area is distributed equally across said screen in both the widthwise direction and the lengthwise direction.

53 . The roller blind of claim 49 , wherein said first longitudinal edge is coupled to said screen along a width of said screen defined in the widthwise direction.
