Beaded chain for blinds |
摘要 |
A differentiated beaded chain is provided as an aid for rotating blind slats in a desired rotational direction. The differentiation is realized utilizing beads of differing sizes or textures along a first and second length of the beaded chain. An operator consistently achieves a desired rotational response by pulling one of the first and second lengths. The differentiated beads are identifiable by either touch or sight. Similarly, a differentiated cord is provided for opening and closing blinds or curtains along a vertical or horizontal plane. The cord consists mainly of a first texture and utilizes a second texture along a portion of a length of the cord to provide an operator with a means for identifying an expected result of tugging on either of the first or second textured lengths.
