  The bell hitting device can be configured to play a melody by providing a plurality of bells having different tone colors. It is also widely used to improve the performance of a mechanical clock and a music box device. In other words, the application forms of this type of bell hitting device have been increasingly diversified in recent years, and in terms of its performance, it has ensured excellent resonance sound generation ability, versatility, ease of assembly, and decoration. Improving performance is considered an important issue. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a bell hitting device configured more rationally.

  The invention described in claim 1 of the present application includes a bell, a hammer for striking the bell, a solenoid for driving the hammer, and a support for supporting them, and the hammer strikes the bell. In the bell hitting device for generating a resonance sound, the bell is supported by the support so as to cover the hammer and the solenoid from above, and the hammer is centered on a shaft portion supported by the support. The solenoid is provided with a flange portion having the shaft portion as a fulcrum, and the solenoid pulls the iron core to the central portion when excited, so that the iron core moves in the vertical direction. The iron core is supported by the upper part of the iron core, and the upper part of the iron core is suspended by the hook part, and is suspended from the hook part. Before leaving Shall iron core is lifted, when exciting the solenoid, said hammer is lifted together with the iron core is moved downwardly, the bell member is a bell member percussion device configured to be struck.

  The invention described in claim 2 of the present application is that, in claim 1, the hammer is capable of plastically deforming at least a part thereof, and adjusting the striking pressure for striking the bell body by plastically deforming the hammer. It is a bell hitting device with a configuration that can be used.

  According to the present invention, it is possible to obtain a bell hitting device configured more rationally.

  Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 5 includes a bell body 100, a hammer 200 that strikes the bell body 100, a solenoid 300 that drives the hammer 200, and a support body 400 that supports them. The hammer 200 strikes the bell body 100 to generate a resonance sound. Its appearance is like a tree.

  The bell body 100 is a cup type made of metal or earthenware, and is supported by the support body 400 so as to cover the hammer 200 and the solenoid 300 from above.

  The hammer 200 swings around a shaft portion 201 supported by the support body 400. The hammer 200 includes a metal striking portion 210 that abuts against the bell body 100 and strikes it, and a flange portion 220 having the shaft portion 201 as a fulcrum.

  When energized, the solenoid 300 pulls the iron core 310 to its central portion. The solenoid 300 is in the form of an elongated pipe, and is supported by the support 400 so that the iron core 310 moves in the vertical direction.

  The iron core 310 is inserted through the center of the solenoid 300, and the upper part 311 of the iron core 310 is locked to the flange part 220 and is suspended from the flange part 220. The upper portion 311 of the iron core 310 is a portion made of a non-magnetic material (for example, brass), and the upper portion 311 is provided with a washer 312 and a caulking portion 313 that prevents the washer 312 from coming off.

  The flange portion 220 has a bifurcated beam at its tip, which sandwiches the upper portion 311 of the iron core 310 and supports the washer 312 from below.

  The support body 400 of this example includes a pedestal portion 410, a cylindrical portion 420 that stands upright from the pedestal portion 410, and a boss portion 430 that is attached to the upper end of the cylindrical portion 420. The solenoid 300 is housed inside the cylindrical portion 420. An opening 421 is provided above the cylindrical portion 420, and the shaft portion 201 of the hammer 200 is supported by a bearing member 422 attached to the opening 421. The flange portion 220 is brought into the cylindrical portion 420 from the opening 421. In addition, the bell body 100 is inserted through a convex portion 423 provided at the upper end of the cylindrical portion 420, and the convex portion 423 is fixed by attaching a convex portion 430.

  In the bell hitting device 1, according to the weight of the hammer 200, the hitting portion 210 of the hammer 200 is separated from the bell 100 and the iron core 310 is lifted. In such a state, the striking portion 210 is positioned approximately directly below the shaft portion 201, and the flange portion 220 extends from the shaft portion 201 in a substantially horizontal direction (see FIG. 3).

  When the solenoid 300 is excited, the iron core 310 moves downward, the hammer 200 is lifted, the striking part 210 collides with the bell body 100, and the bell body 100 is hit (see FIG. 5).

  In addition, the hammer 200 of this example makes it possible to adjust the striking pressure for striking the bell body 100 by plastically deforming at least a part of the hammer 200. Specifically, a metal connecting portion 211 integrally formed with the striking portion 210 can be plastically deformed. That is, the striking pressure for striking the bell body 100 depends on the performance of the solenoid 300, but this may not be set satisfactorily due to variations in the dimensional accuracy and assembly accuracy of the component parts. In this respect, according to this example, fine adjustment is possible, which is very convenient.

  The bell hitting device of the present example described above is unitized in units of supports and has excellent versatility. Excellent decorativeness. In addition, the structure is simple and the processing of the component parts is easy. This is due to the fact that the iron core is suspended from the collar using the weight of the hammer. In addition, it is needless to say that the configuration of each part in the present example can be appropriately changed in design within the technical scope described in the claims, and is not limited to that illustrated in the drawings.

  The bell hitting device of the present invention can be suitably used as a device for generating a resonance sound. In particular, it is possible to provide a melody by providing a plurality of bells having different timbres. Moreover, it can be used suitably also as what improves the performance of a clockwork clock or a music box device.
