  • Patent number: 5447121
    Abstract: An improved method providing safety for young children being escorted from one point to another by adults. The method is non-tethering and non-restraining requiring only direction, to instruction-prone children to hold onto a ring. A number of Dual-Rings (4), forming a plurality of two-position entities, are slid onto a flexible, common center supporting line (2), through a hole in the Dual-Rings and held in place by Dowel Pins (8) which pass through the Dual-Rings and line. One Dual-Ring provides two positions and accommodates two children. The Dual-Ring spacing along the longitudinal axis of the center support line is appropriate to allow children to be escorted without companion interference. The individual ring spacing, of a Dual-Ring entity, is minimal, thus allowing the children to walk closely abreast to one another, in two columns, on narrow sidewalks prevalent in school/ preschool residential areas.
