Title: Plate for indicating the floors and the numbers of stairs of a building

Abstract: On a floor indicating plate to be mounted within a building, the sectional forms and arrows of stairs and numerals representative of the numbers of the stairs are indicated together with numerals representative of floors by the use of only a luminous paint or both the luminous paint and a fluorescent paint. By posting such indicating plate at a prominent place in the staircase between the floors, it is facilitated for an ascender or descender to instantly and precisely judge the present personal situation in the daytime and nighttime, at the failure of electricity or the trouble of an elevator, or in any other case such as outbreak of fire. Thus, it is made possible to confine to the minimum the occurrence of unforeseen injuries which the ascender or descender has heretofore been prone to sustain especially in an emergency.
