Triple curtain sheet and a window shielding apparatus thereof

Abstract

The present invention relates to a triple curtain sheet for a window shielding apparatus, and wherein when a plurality of blind covers( 12 ) are accumulated on a basic mesh sheet( 10 ), each of upper connecting portions( 16 ) of the plural blind covers( 12 ) opened to a lower side is connected to the basic mesh sheet( 10 ) in crossed-weaving type with textile yarns of the mesh sheet, and a plurality of mutually separated opening/closing-type longitudinal yarns( 14 ) are configured on each lower ream( 18 ) of the blind covers( 12 ) in order to be woven on and combined with textile yarns of the blind covers.

1 . A triple curtain sheet for a window shielding apparatus, wherein when a plurality of blind covers( 12 ) are accumulated on a basic mesh sheet( 10 ), each of upper connecting portions( 16 ) of the plural blind covers( 12 ) opened to a lower side is connected to the basic mesh sheet( 10 ) in crossed-weaving type with textile yarns of the mesh sheet, and a plurality of mutually separated opening/closing-type longitudinal yarns( 14 ) are configured on each lower ream( 18 ) of the blind covers( 12 ) in order to be woven on and combined with textile yarns of the blind covers. 
     
     
         2 . The triple curtain sheet of  claim 1 , wherein the opening/closing-type longitudinal yarns( 14 ) are made of complex yarns, and have a thickness of 200 to 3000 deniers. 
     
     
         3 . The triple curtain sheet of  claim 1 , wherein the opening/closing-type longitudinal yarns( 14 ) are made of special yarns such as chanel yarns, wing yarns, tear yarns, and spangle yarns, and have a thickness of 200 to 3000 deniers. 
     
     
         4 . The triple curtain sheet of  claim 1 , wherein the lower reams( 18 ) of the blind covers( 12 ) are woven with LM yarns. 
     
     
         5 . A window shielding apparatus, wherein when a plurality of blind covers( 12 ) are accumulated on a basic mesh sheet( 10 ), each of upper connecting portions( 16 ) of the plural blind covers( 12 ) opened to a lower side is connected to the basic mesh sheet( 10 ) in crossed-weaving type with textile yarns of the mesh sheet, and a plurality of mutually separated opening/closing-type longitudinal yarns( 14 ) are configured on each lower ream( 18 ) of the blind covers( 12 ) in order to be woven on and combined with textile yarns of the blind covers, thereby configuring a triple curtain sheet( 2 ), and wherein when the triple curtain sheet( 2 ) is combined with or fixed to a horizontal slit coupling groove( 32 ) of an axially rotatable driving axial bar( 30 ) between both brackets( 24 ) of a frame( 20 ), the blind covers( 12 ) and the basic mesh sheet( 10 ) of the triple curtain sheet( 2 ) are inserted or fixed into a rear side of the horizontal slit coupling groove( 32 ) and the opening/closing-type longitudinal yarns( 14 ) are inserted or fixed into a front side of the horizontal slit coupling groove( 32 ). 
     
     
         6 . The window shielding apparatus of  claim 5 , wherein the opening/closing-type longitudinal yarns( 14 ) of the triple curtain sheet( 2 ) are made of more than one of complex yarns, chanel yarns, wing yarns, tear yarns, and spangle yarns. 
     
     
         7 . The window shielding apparatus of  claim 5 , wherein the lower reams( 18 ) of the blind covers( 12 ) for constituting the triple curtain sheet( 2 ) are woven with LM yarns.
