ABSTRACT:
An improved combination lock includes a plurality of patches of different daylight fluorescent colors with or without additional nonnumerical indicia, for indicating a predetermined combination. Alternatively, the patches can all be of the same fluorescent color and used as a contrasting background for the additional nonnumerical indicia. The additional nonnumerical indicia can comprise different geometrical patterns including sets of at least three parallel lines, or pictures of different animals. The indicia are preferably made larger than is conventional.
