TECHNICAL FIELD OF THE INVENTION
[0003]
The present invention relates to an automatic bell hitting device for automatically hitting a hanging bell.
[Problems to be solved by the invention]
[0004]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a bell striking device that employs a hammer striking mechanism and has a simple structure and can produce an optimum sound by selecting a hammer head for the size of a bell.
[Means for Solving the Problems]
[0005]
The means of the present invention are as follows.
The bell hanging arm and the hammer for hitting the bell are attached to the base plate of the main body, and the bell and the hammer for hitting the bell are operably provided.A suction solenoid whose mounting position can be adjusted is fixed to one end of the supporting arm. At the other end, a guide horizontal hammer fixed to the hammer for hitting via a fixed arm and provided with a sub-plate mounted on the hammer for hitting and the hammer supporting arm, and supporting the suction plate slidably on the sub-plate, One end of the sliding tube integrated with the hammer pulling wire is fixed to the suction plate side and the other end is fixed to the fixed arm of the hammer, and the hammer is pulled by the operation of suction of the suction plate and returned to the support arm of the hammer by the shaft. That a leaf spring is installed.
BEST MODE FOR CARRYING OUT THE INVENTION
[0006]
In the figure, reference numeral 1 denotes a main body base plate, and 2 denotes a bell. A bell hanging arm 3 fixed to the main body base plate 1 is attached, and the hanging arm 3 and a bell fixing arm 20 fixed to the center of the upper end surface of the bell 2 are attached. They are connected by a synthetic resin shaft 12. A sub-plate 7 on which a bell suspension arm 3, a suction solenoid 4, and a support arm 6 for supporting a hammer 5 are mounted on a main body base plate 1, and a guide in which a suction plate 8 is slidably supported on the sub-plate 7. A horizontal pipe 9 is attached. One end of the hammer 5 for striking and the pulling wire 10 is fixed to the suction plate 8 side, and the other end is fixed to the hammer 5 side. The sub-plate 7 is provided with a guide horizontal tube 9 which slidably supports the suction plate 8. One end of the tension wire 10 of the hammer 5 is fixed to the suction plate 8 side, and the other end is fixed to the hammer 5 side. A return leaf spring 11 is provided on the hammer supporting portion of the hammer fixing arm 6, and returns the hammer that has hit the bell to its original position. A synthetic resin shaft 13 is used to support the bell, and the vibration of the bell is not resonated with the arm 3 so that the bell itself sufficiently resonates. Similarly, a shaft 13 made of a synthetic resin is used for the support portion of the hammer 5 to reduce noise during operation.
[0007]
One end of the hammer pulling wire 10 is connected to the slide tube 22 of the suction plate 8, and the other end is fixed to the fixed arm 21. The solenoid 4 is provided opposite to the suction plate 8 so that the mounting position can be adjusted. When the suction plate 8 is sucked, the hammer 5 hits the bell 2. The return leaf spring 11 is attached near the pivot shaft 13, and the hammer 5 that has performed the hitting operation is returned to the original position.
The slack of the wire causes the hammer to operate smoothly, and the volume can be adjusted by reducing the attraction force of the solenoid. Therefore, the sound of the bell itself becomes extremely natural. Further, if the hammer 5 is made of a real oak and the striking portion is set at 80 °, the striking sound is greatly reduced, and the striking sound is not so loud as the striking sound of flat and spherical surfaces.
[Action]
[0008]
When a momentary voltage is applied to the solenoid, the suction plate is attracted, pulling the wire, driving the hammer and hitting. Then, the hammer returns to the original position by the return leaf spring.
【The invention's effect】
[0009]
According to the present invention, since the hammer is driven by the solenoid, the mechanism is simplified, and the bell and the hammer can be freely exchanged, so that the optimum sound can be obtained by adjusting the weight of the hammer with respect to the weight of the bell. .
