Alarm for emergency



PROBLEM TO BE SOLVED: To speedily and exactly report an emergency state to the outside and to take measures for speedily relieving a victim. SOLUTION: A bell 3 is supported by protruding a supporting shaft 2 at the center of pedestal 1, striking elements 5 for patting the bell 1 through the stress of elastic instruments 4 are respectively installed at several suitable positions of peripheral part, and several lines of guide grooves 6a are opened on a peripheral folded element 1a of pedestal 1 and used as guide grooves for vertically moving the patting elements 5. A lid body 7 in the shape of cover lid forming a folded element 7a is fitted through the elastic force of respective elastic instruments 4 for supporting the striking elements 5 to the pedestal 1 so as to be idly moved up and down, and a notched groove 8 for stopping the respective striking elements 5 at the time of returning these elements is provided at the peripheral part of folded element 7a. When the lid body 7 moves down, at the same time, outer head parts 5a of respective striking elements 5 are pushed down against the elastic force of elastic instruments 4, the lock due to the outer head parts 5a is automatically escaped and released at the position where push-down is fixed, and the bell 3 is simultaneously patted while utilizing the elastic force of elastic instruments 4.
