SUMMARY OF THE INVENTION An object of the present invention is to provide a bell device that can be operated without being directly pressed by a finger or hand and that is excellent in design.

A bell device according to the present invention includes a base portion and a main body portion directly or indirectly supported by the base portion, the main body portion having a striker and an actuator inside thereof, the actuator being The striker strikes the main body from the inside when operated.

Here, the base portion means the base portion of the bell device that can be moved and placed in various places on a desk.
The body portion may be directly connected to the base portion, or may be indirectly attached to the base via another connecting member or the like, and can be struck with a hammer.
In the present invention, the base portion and the body portion as a whole can be designed in various external shapes such as a spherical shape, a laterally elongated elliptical shape, an egg shape, etc., and a tree shape can also be used.

Further, the operation of striking the main body with the striker can be performed by remote control of the actuator.
Further, in the present invention, the striker may be struck by hand operation.
Furthermore, as a countermeasure against the novel coronavirus or the like, a finger or hand may be brought close to the main body, and a change in capacitance may be detected to ring the bell.
In this case, more specifically, the proximity operation by the electrostatic capacitance change of the actuator detects the amount of electrostatic capacitance change when a dielectric such as a finger is brought close to the main body, and operates the actuator. Alternatively, when a dielectric such as a finger is brought close to the main body, the capacitance may be removed immediately before the dielectric contacts the main body.
As a result, it is possible to prevent a finger or the like from being too close to the main body and an electrical discharge phenomenon that causes discomfort between the finger or the like and the main body.

In the present invention, an electromagnet or a solenoid can be used as means for remotely controlling the bell device or controlling it by changing the capacitance.
For example, as an example of the structure of a striker, it has a shaft supporting portion, a striking portion provided on one side, and an action rod provided on the other side. When the striking part provided in is arranged to strike the body part, the body part can be struck by the striking part by projecting the actuator toward the action rod by the magnetic force of the electromagnet or the magnetic force of the solenoid. .
In this case, it is preferable that a biasing force is applied by a spring in the return direction of the actuator so that the impact force is applied to the main body by the striking portion.

In addition, if a spring or the like is applied to the operating member in the return direction, the operating member can be pressed directly with a hand or finger to ring the bell.

In the bell device according to the present invention, since the striking mechanism is provided inside the main body, the appearance of the base and the main body can be variously designed, and the bell device is compact and excellent in design. Become.
Also, the base portion can be placed on various places, such as a table or a counter, and in that case, the placement surface can be made into a gently convex shape so that it can swing.
The bell device according to the present invention can be ringed simply by bringing a finger or hand close to the device without being directly operated by the finger or hand, or by remote control.
In addition, since it can be directly pressed with a finger or the like, it has a basic function of ringing the bell even when electricity is not supplied.
In particular, it has the effect of being able to inform the presence of an urgent mover (operator) by making a sound even if electricity cannot be used in a disaster or emergency situation.

Although structural examples of the bell device according to the present invention will be described below with reference to the drawings, the present invention is not limited thereto.

Example 1 is shown in FIG.
(a) is an external view, and (b) is a cross-sectional view, showing an example of a substantially spherical shape as a whole.
It consists of a base portion 11 and a body portion 12 supported via a support portion 13 provided on the base portion.
In the first embodiment, the outer shape of the base portion 11 is a part of a sphere, and the main body portion 12 has a spherical shape.
Inside the main body, there is a striker 14 that is supported by a shaft supporting portion 14a with respect to a holding portion (not shown).
The striker 14 has a striking portion 14b on one side of the shaft support portion 14a and an action rod 14c on the other side.
As an operating mechanism for striking the inside of the main body 12 with the striker 14, the first embodiment has an operating member 15 that protrudes and retreats toward the action rod 14c.
A coil 16 and a spring 17 biasing the actuator 15 in the backward direction are provided on the outer peripheral side of the actuator 15 .
In FIG. 1, a receiving section for receiving an operation signal from the outside and a power supply section such as a secondary battery are not shown. The element 15 protrudes downward, and the operating rod 14c is rotated downward by the tip portion 15a of the operating element.
As a result, the striking portion 14b rotates upward, and hits the inner side of the body portion 12, producing a sound.
Alternatively, the action rod 14c may be provided with a permanent magnet, and the same or different polarities may be generated by an electromagnetic coil to directly move the action rod 14c.
In FIG. 1, a flat surface 11a is formed on the bottom of the base portion 11, and a predetermined gap d is provided between the base portion 11 and the open end of the main body portion 12, thereby making it easier for sound to echo. .

Example 2 is shown in FIG.
The second embodiment is an example in which the bell can be ringed not only by remote operation using a solenoid but also by hand operation using a fingertip or the like.
The operation button 18 is arranged in the mounting hole 12 a of the main body 12 penetrating vertically, and the operation button 18 is connected to the actuator 15 .
As a result, it is possible to carry out a batting operation by a remote operation using an operation signal from the outside, and it is also possible to ring the bell by hand operation by pressing the operation button 18 .

Example 3 is shown in FIG.
In the third embodiment, the bottom portion of the base portion 11 is formed into a gentle convex surface portion 111a, and the center of gravity is located on the base portion 11 side, so that the bell device can be placed in a swingable manner.
Moreover, as shown in FIG. 3A, the base portion 11 and the main body portion 12 are formed in an oblong elliptical shape.

Example 4 is shown in FIG.
The fourth embodiment is an example in which a container portion 21 that can be split in half in the horizontal direction and a bell device are accommodated inside a lid portion 22 .
In this embodiment, the threaded portion 21b on the container portion 21 side and the threaded portion on the lid portion 22 side are screwed together.
A flat portion 21 a is provided at the bottom of the container portion 21 .
As a result, as the appearance is shown in FIG. 4(a), it has a spherical shape without gaps.
Also, by forming the lid portion 22 from an easily deformable (deformable) material and combining it with the second embodiment shown in FIG. .

FIG. 5 shows an example of a tree-shaped bell device.
As long as the operation mechanism is provided inside the main body in this manner, there is no restriction on the external shape.

In FIG. 6, by providing a detection means (capacitive proximity sensor, etc.) for the change in capacitance in the main body, the change in capacitance when a dielectric such as a finger is brought close to the main body is detected. A bell can be operated by a solenoid or the like by setting a threshold value.
As the capacitance detection sensor, for example, a known high-frequency oscillation circuit and its oscillation state may be detected.
FIG. 6 shows a change in capacitance when a solenoid and a capacitive proximity sensor are provided in the main body and a finger is brought close to the main body of the bell device.
From this, it can be seen that the ON/OFF control of the bell device can be performed by setting a threshold value for the capacitance change amount.
