Safety roman blind

Abstract

A safety roman blind includes a shielding web unit disposed rearwardly of a blind curtain and having a web sheet attached to the blind curtain at a plurality of attached and attaching spots arranged along fold lines, and a casing disposed on the web sheet to receive and shield a pulled cord segment of a lift cord so as to prevent strangulation accidents.

1 . A safety roman blind comprising:
 a headrail extending in a longitudinal direction;   a blind curtain having an upper end portion which is connected to said headrail, and extendable in an upright direction transverse to the longitudinal direction to terminate at a lower end portion, said blind curtain being configured to have a plurality of fold regions which are displaced from each other in the upright direction by a plurality of droopable regions such that when said lower end portion is lifted to a raised position, said droopable regions are brought into a stacked arrangement with each other in a transverse direction that is transverse to the longitudinal and upright directions, each of said fold regions having a plurality of attached spots which are displaced from each other along a folded line;   at least one lift cord having a pulled cord segment which is disposed rearwardly of a rear major surface of said blind curtain, and which has a terminal end that is secured to a lowermost one of said fold regions, said pulled cord segment being suspended from said headrail and liftable along a lifting path in the upright direction such that said terminal end is displaceable to the raised position by a lifting force applied to said lift cord; and   a shielding web unit having a web sheet which is extendable in the upright direction, and which has a plurality of attachment regions that are displaced from each other in the upright direction, each of said attachment regions having a plurality of attaching spots which are displaced from each other along an attachment line and which are in mated attachments to said attached spots of a corresponding one of said fold regions to bring the attachment and fold lines in line with each other, said attaching and attached spots being offset from the lifting path, said web sheet being made from a web material thinner and lighter than that of said blind curtain such that, when said lower end portion is lifted to the raised position, said web sheet is bent away from said fold regions so as not to be trapped in between said droopable regions, thereby preventing lifting movement of said pulled cord segment along the lifting path from being obstructed.   
     
     
         2 . The safety roman blind as claimed in  claim 1 , wherein said shielding web unit has at least one casing which defines a channel extending along the lifting path to receive said pulled cord segment therein, and which is attached to said web sheet along the lifting path and between two adjacent ones of said attaching spots of each of said attachment regions. 
     
     
         3 . The safety roman blind as claimed in  claim 2 , wherein said shielding web unit is made from a netting material, said casing being integrally formed with said web sheet by stitching. 
     
     
         4 . The safety roman blind as claimed in  claim 3 , wherein said blind curtain has a plurality of weighting rods disposed on said fold and droopable regions, respectively. 
     
     
         5 . The safety roman blind as claimed in  claim 3 , wherein said casing is attached to a rear major surface of said web sheet distal from said blind curtain. 
     
     
         6 . The safety roman blind as claimed in  claim 3 , wherein said casing is attached to a front major surface of said web sheet proximate to said blind curtain.
