Abstract: 503,774. Window blinds. HARRISON, W. RHODES-. Oct. 11, 1937, No. 27611. [Class 20 (iii)] The lateral stay and guide members 18, 19, of a roller blind for a verandah, balcony, or the like, are mounted on pivots 23, 24 near their upper ends, whereby they may be rotated into a horizontal position below the blind when the latter is in the raised position. The members 18, 19 are retained in the vertical position by springs 65, 66 at the rear of the blind, which are connected to the fixed structure at the top of the' blind and to swivelling members 69, 70, near the lower ends of the guide members. These springs also serve to assist the rotation of the members 18, 19, into the horizontal position, after the axial lines of the springs move inwardly beyond the pivots 23, 24. The guides are of box section with slots 20 to permit the passage of pins 36, 37, mounted at the ends of the bottom bar 35 and which also carry guide rollers 40, 41. The bottom bar is in the form of a heavy cylinder which serves to extend the blind when released. Pivoted latch members 46, 47 are mounted at the lower ends of the guides 18, 19, and engage the pins 36, 37, to retain the blind in the lowered position. The operating cord 15 passes over a pulley 52 mounted with its axis parallel to the plane of the blind, and a second pulley 53 mounted on the pivot 23. The latter pulley is provided with flanges 54 which prevent disengagement of the cord 15. The cord is attached to a spring 57, the lower end of which is attached to a spring 59 engageable with retaining hooks 61, 63, attached to the guide 18. The spring maintains the cord 15 taut when the blind is raised or lowered.
