Abstract
Abstract An emergency evacuation path marking system employing a series of devices, each device having the tactile characteristics of shape and surface contacts, in combination, to indicate direction and distance to the nearest evacuation exit; the shape providing direction information and the surface contacts providing distance information. The devices also being capable of luminescence to aid in visual as well as tactile reference.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
165 words
A system for tactually indicating both the direction of an escape route and the distance to an exit thereof for use in a building structure having a floor and wall along which a person will move in following the escape route, comprising, in combination: a plurality of arrow-shaped members secured to the wall at determined spaced apart locations along the escape route in a position to be touched by the hand of a person moving along the floor adjacent the wall, said members being arranged with the smaller end pointing in the direction of the exit of the escape route; and each member having on an exposed surface, to be readily touched and counted by a person moving along the escape route, an ordered number of contact points wherein the number is related to the distance to such exit from each such member, whereby a person moving along the floor may tactually determine the direction to the exit and the distance at each such member.
Claim 2
Independent Claim
165 words
A system for tactually indicating both the direction of an escape route and the distance to an exit thereof for use in a building structure having a floor and wall along which a person will move in following the escape route, comprising, in combination: a plurality of arrow-shaped members secured to the wall at determined spaced apart locations along the escape route in a position to be touched by the hand of a person moving along the floor adjacent the wall, said members being arranged with the smaller end pointing in the direction of the exit of the escape route; and each member having on an exposed surface, to be readily touched and counted by a person moving along the escape route, an ordered number of contact points wherein the number is related to the distance to such exit from each such member, whereby a person moving along the floor may tactually determine the direction to the exit and the distance at each such member.
Claim 3
Dependent Claim
35 words
The system defined in claim 1 wherein said members are arranged in a pair of horizontally extending vertically spaced apart rows at heights above the floor within the reach of a person walking or crawling.
Claim 4
Dependent Claim
51 words
The system defined in claim 2 wherein the arrangement of said members includes an array of devices at one side of a door, said array being on that side of the door in the direction of the exit and in such numbers to indicate the number of doors to the exit.
Claim 5
Dependent Claim
16 words
The system defined in claim 1 wherein the contact points are discrete protuberances discernible by touch.
Claim 6
Dependent Claim
13 words
The system defined by claim 1 wherein the contact points are discrete depressions.
Claim 7
Dependent Claim
28 words
The invention defined by claim 1 wherein the number of contact points on each member is related to the number of doors from such member to the exit.
Claim 8
Dependent Claim
15 words
The system defined by claim 1 wherein means are provided for reordering said members luminous.
Claim 9
Dependent Claim
28 words
The system defined by claim 7 wherein the luminosity is provided by means responsive to human touch for causing said members to be illuminated from an electrical source.
