摘要

in the field of persian and / or shutters blinds is a very important system of link, drag and junction of the various elements that are horizontal.at present, all of this is achieved through the direct connection of an appropriate appendix of an element with a proper location of the next, and so on (fig.a of dis.), or by using an accessory that serves as a hinge flap (r in fig. b of the dis.), and several other variants but in substance it can be traced back to one or both of the two systems described.as in the patent is a system of lateral drag place at the ends of the scatolati. this drag is obtained through the elements. (fig. and the dis.), consisting of two pins (p), which engage the ends of the scatolati (1). their distance is such that the two scatolati can detach the distance d (fig. c of dis.).once the end of scatolati and grafted in the lateral guides, no longer have the opportunity to go out (u).this represents only the tip of the scatolati found that are easier to produce.
