Abstract

PURPOSE:To simplify the constitution and operation, by combining the elastic knocker, lever with magnet and eccentric cam. CONSTITUTION:The eccentric cam 8 is borne at the shaft 10 and the lever 6 with the magnet 5 is borne at the shaft 7 via the return spring 11, one end of the elastic knocker 1 is fixed at the main body 2 projecting the stripper 12 from the long hole 14 so that the lower surface is in contact with the glass 4 from the opening of the main body 3. Thus, when the position of the stripper 12 is set and the eccentric cam 8 is turned via the shaft 10, the lever 6 moves toward the arrow, the magnet 5 is lifted up with the condition that is absorbs the elastic knocker 1. When the elastic knocker 1 shocks on the stripper 12, it is separated from the magnet 5 to knock the surface of the glass 4 with the spring force. It shows the vibration near the condition when the glass 4 is destroyed to perform the operation test of the glass destruction sensor fixed on the surface of the glass 4.
