875,884. Lath blinds. MULLER, H. Dec. 15, 1958, No. 40407/58. Class 20(3) The wood, plastic, steel &c. slats, Figs. 6 and 7 of a lattice roller blind are movably connected by laterally spaced links 2 hooked at their upper ends 11, and engage in recesses 3 in an adjacent slat, each link being displaceable up and down in the recess 3 and the outside of the hooked end has a rolling curve and each recess is partly closed by a projection 4 shaped so that a hook can only be inserted into a recess when the hook is at an angle approaching a right angle to the recess and is engaged therein by relative turning movement of the slats. The link 2 and projection 4 may form one piece with the slat 1 or they may be attached by welding, screwing, cementing &c. The edges 9, Fig. 6 of parts such as bridge pieces 8 in a hollow slat contact the links 2 and prevent relative lateral movement of the slats. The edges of recesses in solid slats perform the same junction and the link 2 may be inserted by pressing into previously formed slats 13 or directly into a synthetic plastic slat softened by warming. The link 2, Fig. 8, has tabs 14 which lie against the link when pressed into the slot and spread against a rib 12, Fig. 7, when the link is drawn out to a limited extent. The end slat 5, Fig. 2, has preferably flexible flanges 10 in one piece therewith or secured thereto to prevent the blind being drawn completely into the blind box.
