Abstract
Abstract The jumping reflex-reflectors disclosed are eye-catching attention-getting safety devices. They have at least one primary rotatable part, an axis means establishing a predetermined axis for rotation of the primary rotatable part, and holding means for the axis means to permit the rotation, especially a wind-actuated rotation. The primary rotatable part comprises a form-retaining body, preferably a base sheet material. This base sheet is aligned with substantially all portions of it extending substantially parallel with the predetermined axis for its rotation. It is contoured at least in portions outwardly from the axis; and patterned areas of reflex-reflecting material and of non-reflex-reflecting material (preferably fluorescent) are disposed on opposite sides of it. The patterned area of reflexreflecting material on one side is relatively displaced in axial relationship from the patterned area of reflex-reflecting material on the other side. In all cases, at least 50 percent of the area coverage of each reflex-reflecting pattern on opposite sides of the sheet material is in locations relative to the axis which do not coincide as viewed during rotation of the rotatable part. The patterned areas of non-reflex-reflecting material on opposite sides of the sheet material also are relatively displaced in axial relationship to each other. The arrangement is such that, at substantially all practical rotation speeds for the primary rotatable part about the predetermined axis, a viewer under reflex-reflecting conditions gains the impression of shifting flash patterns of light return suggestive of the patterns of the areas of reflex-reflecting material. A variety of rotatable bodies and reflex-reflecting pattern arrangements are disclosed.
