The present invention relates to a bell ringing device in which a pendulum is oscillated and displaced by driving a drive motor, and the bell is struck by the oscillating and displaced pendulum.

Conventionally, wind chimes have been widely used that use a natural wind force to swing a bell pendulum suspended inside a bell made of glass or metal. Since this type of wind chime uses natural wind power, it cannot be sounded when there is no wind or indoors.

Therefore, an electronic wind chime has been proposed in which the wind chimes can be enjoyed even in an atmosphere where natural wind cannot be obtained, for example, in a closed room.

For example, Japanese Patent Laid-Open No. 11-104361 (Patent Document 1) discloses a wind chime in which a pendulum including a magnet is electromagnetically driven and a bell is hit by the electromagnetically driven pendulum.

As shown in FIGS. 1 and 2, the bell ringing device according to the present embodiment includes a support column 2 that supports a bell body 1 formed in a bell shape with the lower side released, and a support base that fixes the support column 2. A stand 3 is provided. The bell body 1 is suspended from the distal end side of a support arm 4 formed by bending the distal end side of a column 2 fixed to the support base 3 substantially at a right angle. The support column 2 for hanging and supporting the bell body 1 is formed of a hollow tubular body so that the conductive wire 5 can be inserted.

The support base 3 is formed as a casing, and a power supply unit 8 for supplying power to a drive motor 7 that swings and displaces a pendulum 6 that strikes and rings the bell 1 is provided therein. An electronic circuit unit 9 including a circuit board constituting a control unit that controls driving of the drive motor 7 is provided. The power supply unit 8 is formed as a battery box on the support base 3, and a primary battery 10 or a rechargeable secondary battery is detachably stored therein. The power of the power supply unit 8 is also supplied to the electronic circuit unit 9 to operate the electronic circuit unit 9.

By the way, the bell body 1 is inserted into the support column 2 and supported by being suspended from the front end side of the conductive wire 5 drawn from the front end portion of the support arm 4. The conductive wire 5 is electrically connected to a power supply unit 8 provided on the support base 3 and is used as a power supply line for supplying power to the drive motor 7.

And, as shown in FIG. 2, the conductive wire 5 is drawn out from the tip of the support arm 4 to the inside of the bell body 1 through a through hole 11 formed at the center of the top of the bell body 1, By attaching a retaining member 12 having a diameter larger than that of the through-hole 11 to the distal end side, the bell body 1 is supported by being suspended.

In the present embodiment, since the drive motor 7 is attached to the tip of the conductive wire 5 inserted into the bell body 1, the drive motor 7 is used as a retaining member from the conductive wire 5 of the bell body 1. You may make it use.

The middle portion of the conductive wire 5 drawn out from the tip of the support arm 4 is wound around a hanging tool 13 attached to the support arm 4 so that the load concentrates on the lead-out portion from the support arm 4. I try to prevent that.

In the present embodiment, the bell 1 is suspended and supported on the conductive wire 5 used as the power supply line. However, in order to prevent a large load from being applied to the conductive wire 5, it is independent of the conductive wire 5. It is also possible to suspend and support the hanger 13 attached to the support arm 4 using a hanger provided on the hanger.

A connecting member 16 for connecting the pendulum 6 is attached to the rotary shaft 15 of the drive motor 7 disposed in the bell body 1. The connecting member 16 is formed of a rigid member such as metal or synthetic resin, and is attached so as to rotate integrally with the rotating shaft 15.

The pendulum 6 that strikes the bell 1 is formed using a metal material. In the present embodiment, as shown in FIG. 2, the pendulum 6 is formed in a rhombus shape with the central portion cut out, but the shape can be selected as appropriate.

In this embodiment, since the drive of the drive motor 7 is controlled by a drive pattern signal that is a pulse signal as will be described later, it is desirable to use a stepping motor that enables intermittent rotation drive.

Then, in this embodiment, the power switch 18 of the support base 3 to switch the supply of power is provided. When the power switch 18 is switched from the on state to the off state, the power supply to the drive motor 7 is switched from a state where power can be supplied to the supply stop state, and the ringing operation of the bell body 1 by driving the drive motor 7 is stopped.

Here, as shown in FIG. 2, when the strip-shaped wind receiving body 21 is suspended from the pendulum 6 by using a wire material such as a hanging thread 20 that is bent and deformed, the wind receiving body 21 receives the wind and shakes. By swinging the pendulum 6, the bell body 1 can be struck. Therefore, in the present embodiment, it is possible to ring the bell 1 using the natural wind by setting the power switch 18 to the OFF state to stop the supply of power to the drive motor 7 to the inoperative state. It becomes. Thus, the bell ringing device according to the present embodiment uses the drive of the drive motor 7 or stops the drive motor 7 to ring the bell 1 using natural wind. Therefore, it is possible to select a method for ringing the bell body 1 according to the installation environment.

And this Embodiment is provided with the control part 22 which drives the drive motor 7 and controls the operation | movement which rocks and displaces the pendulum 6 and rings the bell 1.

As shown in FIG. 3, the control unit 22 is operated with power supplied from the power supply unit 8.

The drive interval setting unit 23 has a built-in timer and outputs a drive signal for rotating the drive motor 7 at a preset time interval. The drive interval setting unit 23 includes, for example, a dip switch, a timer is controlled by setting the dip switch, and a time for outputting a drive signal is set. The drive interval setting unit 23 is set to output a drive signal at an appropriate time interval such as 0 minutes, 5 minutes, 10 minutes, 30 minutes, 60 minutes, etc. by operating a dip switch.

Further, the drive pattern signal stored in the storage unit 24 is stored as a pulse signal as shown in FIG. As shown in FIG. 4, the drive pattern signal is composed of four parameters, ie, pulse width, pulse period, number of pulses, and group pulse period. The motion pattern of the pendulum 6 can be changed by appropriately changing these parameters and changing the drive pattern of the drive motor 7. When the movement pattern of the pendulum 6 is changed, the pattern in which the pendulum 6 strikes the bell 1 is changed, and the ringing pattern is changed. Therefore, by appropriately setting the drive pattern signal stored in the storage unit 24, it is possible to change the ringing pattern and generate sounds of various timbres, and to listen to wind chimes without any sense of incongruity. And by changing a drive pattern signal for every drive time set by the drive interval setting part 23, the bell 1 can be ringed with a different ring pattern for every set time interval.

Furthermore, in the present embodiment, the control unit 22 is provided with a drive time setting unit 26 that sets a drive time that allows the drive motor 7 to be driven. In the drive time setting unit 26, the time during which the drive motor 7 can be driven is set to 6 hours, 8 hours, 12 hours, and 16 hours, for example. In this ringing device, the drive motor 7 can be driven only during the time set by the drive time setting unit 26. When the set time has elapsed, a drive signal is output from the drive interval setting unit 23. Even if it is output, the drive of the drive motor 7 is prohibited and the ringing is stopped. Thereby, the time zone which does not want to ring at night etc. can be set.

For example, as shown in FIG. 1, the human body detection sensor 27 is provided on the upper surface of the support base 3. The human body detection sensor 27 outputs a detection signal by contact of a human finger or the like, or detects a physical change caused by the movement of the person, for example, a change caused by a movement of the human body, such as a vibration or light blocking. Then, a sensor that outputs a detection signal is used.

Then, when a human body detection signal is input from the human body detection sensor 27, the drive control unit 25 outputs an activation start signal that activates the drive interval setting unit 23 and the drive time setting unit 26, and the drive interval setting unit 23 and the drive Time advancement of the time setting unit 26 is started, and within a preset time, the drive motor 7 is driven at a predetermined time interval to swing and displace the pendulum 6 to start the ringing of the bell 1.

The drive interval setting unit 23 outputs a drive signal simultaneously with the output of the start start signal when the start start signal is output from the drive control unit 25, and is driven according to the drive pattern signal read from the storage unit 24. The motor 7 may be driven. In this case, the time interval set by the drive interval setting unit 23 is 0 minutes.

The light detection sensor 28 is desirably provided on the upper surface of the support base 3 as shown in FIG. 1 in order to reliably detect the light state of the environment where the ringing device is installed.

Note that the light detection sensor 28 may be used as an activation start switch. In this case, since the lighting of the illumination can be detected and the ringing of the bell body 1 can be started, practicality can be improved.

In the bell ringing device configured as described above, the start switch 27 is operated in a state where the power switch 18 is turned on and power can be supplied from the power supply unit 8 to the drive motor 7. When the activation start signal is output, the drive control unit 25 outputs an activation start signal for activating the drive interval setting unit 23 and the drive time setting unit 26, and the time of the drive interval setting unit 23 and the drive time setting unit 26 is output. Within a preset time, the driving motor 7 is driven at a predetermined time interval to cause the pendulum 6 to swing and displace the bell 1 to start. At this time, a command signal for reading the drive pattern signal stored in the storage unit 24 is output from the drive control unit 25, and the drive pattern signal set for each drive interval set by the drive interval setting unit 23 is stored from the storage unit 24. The drive motor 7 is driven with the drive pattern corresponding to the read drive pattern signal.
