Abstract
In a motor driven type gong striking mechanism, the rotation of the main shaft of an electric motor is converted through a crank mechanism into the oscillation of a piston plate, a gong striking hammer is coupled through a spring to the piston plate so that the hammer is oscillated, and a gong is disposed in the range of oscillation of the hammer. Thus, as a result of the rotation of the motor, the hammer is oscillated to strike the gong provided in the stroke of the hammer.
Claims8
A motor driving type gong striking mechanism, which comprises:
- a driving electric motor a driving electric motor mounted on a frame within a gong;
- a piston plate supported on the frame and adapted to pivotally move back and forth in a substantially oscillatory motion from a first position to a second position and then back to the first postion in accordance with the rotation of the main shaft of said electric motor;
- a pivotally movable transmission means for directly and continuously transmitting the rotation of the motor to said piston plate;
- a hammer;
- the gong spaced from the hammer and adapted to be struck by the hammer;
- support means on the frame for supporting the hammer for oscillation;
- spring means coupling the hammer to the piston plate for biasing and releasing such bias in response to oscillation of the piston plate to thereby cause oscillation of the hammer and cause the gong to be struck thereby.
