PURPOSE:To enhance the efficiency of the work of sticking a semi-translucent sheet to bones and reduce the storing space for a fire bag by dividing the fire bag into a pair of half-division bodies in its horizontal or vertical direction, and integrating both half-division bodies together when in use and fitting one half-division body with the inside of the other half-divided body when storing the fire bag. CONSTITUTION:A fire bag 3 is in the shape of a cage and formed by a plurality of longitudinal bones 8 for connecting an upper annular member 6 and a lower annular member 7 together and a circumferential cross bone 9 for connecting the middle portions of the longitudinal bones, and the bone 9 is divided into an upper cross bone 9a and a lower cross bone 9b and so the fire beg 3 comprises a pair of an upper-half division body 3a and a lower-half division body 3b. The division bodies 3a, 3b are assembled into a full sphere by engagement of male and female engagement portions 10, 11 provided on the inner periphery of the bone 9a and the outer periphery of the bone 9b, respectively. After the fire bag is used, legs, etc., are removed therefrom and are further decomposed, and the engagement portions 10, 11 of the bones 9a, 9b are separated from each other and the division body 3b is inserted into the division body 3a and is fitted with the inside thereof. Then the capacity of the fire bag is reduced to about half of that when it is assembled. |
