DOOR HANDLE WITH A FUNCTION OF SENSING THE PROPAGATION DEGREE OF A FIRE BY SENSING A TEMPERATURE RISING OVER ROOM TEMPERATURE FOR SENSING SYMPTOMS OF A FIRE AND A BACK DRAFT

摘要

PURPOSE: A door handle with a function for sensing the propagation degree of a fire by sensing a temperature rising over room temperature is provided to include a color changing layer in which a color is changed according to temperature, thereby easily confirming symptoms of a fire and a back draft by sensing changes in the temperature of an indoor space with the unaided eye.;CONSTITUTION: A door handle with a function for sensing the propagation degree of a fire by sensing a temperature rising over room temperature comprises a body unit(100), a fixing unit(200), and a color changing layer(300). The color changing layer is formed in one or more surfaces of the body unit and the fixing unit, thereby changing color according to temperature. One or more color changing substances which vary in color when the temperature is over a predetermined temperature are coated on one or more surfaces of the body unit and the fixing unit and sorted into two or more sections according to a temperature change so that a gradual temperature change is determined. A protective film is formed on the color changing layer, thereby preventing damage to the color changing layer.;COPYRIGHT KIPO 2013
