ABSTRACT:
This invention relates to a fastening member for securing the slats of a venetian blind onto a flexible support element and to the method of assembling such slats to the support elements. The fastening member comprises a generally "U" shaped member in which the legs of the "U" have at their outer ends laterally outwardly extending abutments for engagement on one side of the slat while the remainder of the fastening member extends through an opening through the slat. A loop on the flexible support element passes between the legs of the "U" thus tending to hold the abutments in engagement with the surface of the slat. On the opposite side of the slat cam locks are provided such that upon flexure of the legs toward each other the cams will pass through the opening in the slat and then upon release when the legs resume their normal position the cams will engage and lock the slat in position between the cam locks and the aforesaid abutments. A narrow entrance slot with a tapered entrance throat provides for passage therethrough of the loop thus permitting passage of the loop between the legs into the space therebetween. Importantly, the fastening member is so dimensioned in one direction that the abutments are larger than the opening in the slat. In a second direction substantially perpendicular to said first direction the fastening member is dimensioned to pass through the opening in the slat. After engagement with the loop the fastening member is passed through the opening in the slat, rotated 90 degrees, and then all but the abutment portion of the fastening member is snapped back through the opening.
