Summary of the Invention

Problem to be Solved by the Invention

[0004] An object of the present invention is to provide a bell device that can be operated without being directly pressed by a finger or a hand and is also excellent in design.

Means for Solving the Problem

[0005] 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, wherein the main body portion has a striker and an actuator inside, and the striker strikes the main body portion from the inside when the actuator is operated.

[0006] Here, the base portion refers to a base portion of a bell device that can be moved and placed in various places in a desktop type. The main body may be directly connected to the base, or it may be indirectly attached to the base via other connecting members, and it can be struck with a striker. In this invention, the base and main body can be designed to have various external shapes, such as a spherical shape, a horizontally elongated ellipse shape, or an egg shape, and can also be made into a tree shape.

[0007] Furthermore, the operation of striking the main body with the striker can be performed by remotely controlling the actuator. Furthermore, in this invention, the striker may also be operated manually to produce a sound. Furthermore, as a countermeasure against COVID-19 and other viruses, the device may be designed to sound a bell when a finger or hand is brought close to the main unit to detect a change in capacitance. In this case, more specifically, the proximity operation by changing the capacitance of the actuator may involve detecting the amount of change in capacitance when a dielectric such as a finger is brought close to the main body and operating the actuator, or the capacitance may be removed just before the dielectric comes into contact with the main body when the dielectric such as a finger is brought close to the main body. This prevents the occurrence of an unpleasant discharge phenomenon between the finger or other body part and the device, which can happen if the finger or other body part is brought too close to the device.

[0008] In this invention, electromagnets and solenoids can be used as means for remotely controlling the bell device or for operating it by changing capacitance. For example, a striker structure might consist of a pivot, a striking part on one side of the pivot, and an action rod on the other side. When the action rod is moved up and down using the actuator with the pivot as a fulcrum, the striking part on the opposite side of the fulcrum strikes the main body. By using the magnetic force of an electromagnet or solenoid to make the actuator protrude towards the action rod, the main body can be struck by the striking part. In this case, it is preferable that a spring is used to apply a biasing force to the actuator in the return direction so that an impact force is applied to the main body at the striking part.

[0009] Furthermore, by applying a biasing force in the return direction to the actuator using a spring or the like, the actuator can be pressed directly with a hand or finger using an operating button to ring the bell. [Effects of the Invention]

[0010] The bell device according to the present invention has a striking mechanism inside the main body, allowing the base and the main body to have various design appearances, resulting in a compact and aesthetically pleasing bell device. Furthermore, the base can be placed on various surfaces, such as tables or counters, and the mounting surface can be made into a gently convex shape, allowing it to swing. The bell device according to the present invention can be rung simply by bringing a finger or hand close to it, or by remote operation, without directly operating it with a finger or hand. Furthermore, since it can also be operated by directly pressing it with a finger, it has the basic function of ringing the bell even when the power supply is cut off. In particular, in disasters and emergencies, even if electricity is unavailable, the sound emitted can be used to urgently signal the presence of the operator. [Brief explanation of the drawing]

[0011] [Figure 1] An example of the bell device according to the present invention is shown. [Figure 2] Example 2 is shown. [Figure 3] Example 3 is shown. [Figure 4] Example 4 is shown. [Figure 5] Example 5 is shown. [Figure 6] This shows an example of capacitance change when a dielectric material is brought near. [Modes for carrying out the invention]

[0012] Examples of the structure of a bell device according to the present invention will be described below with reference to the figures, but the present invention is not limited to these examples.

[0013] Example 1 is shown in Fig. 1 (a) is an external view, and (b) is a cross-sectional view, which is an example of a substantially spherical shape as a whole It consists of a base portion 11 and a main body portion 12 supported via a support portion 13 provided on the base portion Example 1 is configured such that 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 portion, a striker 14 pivotally supported by a pivot support portion 14a is provided for a holding portion (not shown) The striker 14 has a striking portion 14b on one side of the pivot support portion 14a, and an operating rod 14c on the other side As an operating mechanism that strikes and sounds the inner side of the main body portion 12 with the striker 14, Example 1 is an example having an actuator 15 that protrudes and retracts toward the operating rod 14c On the outer peripheral side of the actuator 15, there are provided a coil 16 and a spring 17 that biases the actuator 15 in the retracting direction In Fig. 1, illustration of a receiving portion that receives an external operation signal and a power supply portion such as a secondary battery is omitted. When a driving current is supplied to the coil 16, the actuator 15 protrudes downward against the biasing force of the spring 17, and the tip portion 15a of the actuator rotates the operating rod 14c downward As a result, the striking portion 14b rotates upward, so that it strikes the inner side of the main body portion 12 and a sound is produced Alternatively, the operating rod 14c may be provided with a permanent magnet, and the same polarity or opposite polarity is generated by the electromagnetic coil to directly move the operating rod 14c In Fig. 1, a flat surface 11a is formed on the bottom of the base portion 11, and by providing a predetermined gap d between the base portion 11 and the open end of the main body portion 12, sound can easily reverberate

[0014] Example 2 is shown in Fig. 2 Example 2 is an example that is not limited to remote operation by a solenoid, and can also ring a bell by manual operation with a fingertip or the like An operation button 18 is disposed in a mounting hole 12a of the main body portion 12 penetrating in the vertical direction, and the operation button 18 is connected to the actuator 15 This allows for remote operation via external control signals to trigger the bell, and also enables the bell to be rung by manually pressing the control button 18.

[0015] Figure 3 shows Example 3. In Example 3, the bottom of the base portion 11 is made into a gently convex portion 111a, and the center of gravity is on the base portion 11 side, so that the bell device can be mounted in a swingable manner. Furthermore, as shown in Figure 3(a) of the external appearance, this is an example where the base portion 11 and the main body portion 12 are made into a horizontally elongated ellipse shape.

[0016] Figure 5 shows Example 4. This embodiment 4 is an example in which a container section 21 that can be split in half horizontally and a bell device are housed inside the lid section 22. This embodiment shows an example where the threaded portion 21b on the container portion 21 and the threaded portion on the lid portion 22 are screwed together. Furthermore, a flat portion 21a is provided at the bottom of the container portion 21. As a result, it has a seamless spherical shape, as shown in Figure 4(a). Furthermore, by forming the lid portion 22 from a material that is easily deformable (deformable) and combining it with the embodiment 2 shown in Figure 2, the operation button 18 can be pressed by crushing the top portion.

[0017] Figure 5 shows an example of a bell device arranged in a tree shape. Thus, as long as the operating mechanism is located inside the main body, there are no restrictions on the external shape.

[0018] As shown in Figure 6, by providing a means for detecting capacitance changes (such as a capacitive proximity sensor) in the main body, the capacitance change when a dielectric object such as a finger is brought close to the main body can be detected, and by setting a threshold value, the bell can be operated using a solenoid or the like. The capacitance detection sensor may be a known one, for example, a high-frequency oscillation circuit and a sensor that detects its oscillation state. Figure 6 shows the change in capacitance when a finger is brought close to the main body of the bell device, with a solenoid and a capacitive proximity sensor installed in the main body. This demonstrates that the bell device can be controlled ON / OFF by setting a threshold for the change in capacitance. [Explanation of Symbols]
