DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable alarm clock using phosphorus as a sounding body.

[0002]

2. Description of the Related Art As a conventional portable alarm clock, a lid is hingedly connected to a main body. When the portable alarm clock is carried, the lid is closed to cover the main body, and when used, the lid is rotated at a hinge portion as a stand. It is placed on a desk and used. The alarm device is provided on the main body side, and there are some which sound a piezoelectric buzzer.

[0003]

In a conventional alarm device for a portable alarm clock, since a device using a piezoelectric buzzer is used as described above, a sufficiently loud sound cannot be produced. To make the alarm sound louder,
The method of striking phosphorus is desirable, but it is necessary to reduce the size so that it is easy to carry, and there is not enough space to use the phosphorus method.

[0004]

In order to solve the above-mentioned problems, the present invention fixes phosphorus on a stand.
Lin can cover and cover the time display section of the timepiece body and at the same time be hit by the drive device to emit a loud alarm sound.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the present invention, a watch main body and a stand for supporting the watch main body in an upright state are hinged, and the stand has a size for covering a time display section of the watch main body. A phosphorus is fixed, and a phosphorus driving device is provided on one of the watch body, the stand portion, and the phosphorus.

[0006] It is preferable that the above-mentioned stand has a cover shape for covering phosphorus. Further, it is preferable that a sound emission hole for emitting a sound from phosphorus is formed in the cover-like stand portion. Further, the above-mentioned stand may be formed in a belt shape.

[0007] In the case of a cover-like stand, it is preferable that the driving device is disposed in a space outside the phosphorus of the stand. Further, the above driving device may be provided on the timepiece main body side. Further, the driving device may be a piezoelectric element adhered to phosphorus.

[0008] In the portable alarm clock configured as described above, phosphorus is struck by the drive device to generate a loud alarm sound, and the time display unit is covered and covered with phosphorus to achieve the same as the conventional alarm clock. To keep the watch compact and protect the watch.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a timepiece body 1 having a time display section 1a provided on the front side in a protruding state, and a stand section 2 for supporting the timepiece body 1 in an upright state. Are connected by a hinge 3 so as to be openable and closable. The stand 2 has a cover shape, and has a time display 1 inside.
A phosphorus 4 large enough to cover a is fixed by screws 5.

A driving device 6 is provided in the space inside the stand portion 2 and outside the phosphorus 4. The driving device 6
The motor comprises a motor 6a, a rotary shaft 6b fixed to a drive shaft of the motor, and a hit ball 6c connected to both ends of the rotary shaft so as to be movable in a radial direction. Motor 6
As a, a DC motor such as a flat coreless motor or a thin ultrasonic motor is used. In order to supply a drive signal to the motor 6a, a drive circuit in the timepiece body 1 and the motor 6a are connected through a vicinity of the hinge 3 using a flexible cable or a flat cable (not shown).

With such a configuration, the watch can be made compact by rotating the stand 2 around the hinge 3 and covering the time display 1a with the phosphorus 4 as shown in FIG. The shape is suitable for carrying.

When a timepiece is used, as shown in FIG. 1 (a), the stand 2 is rotated about 270 degrees about the hinge 3 so that the phosphorus 4 is separated from the time display 1a. Place on. The hinge 3 and a part of the stand portion 2 are in contact with the surface of the table T, and the phosphorus 4 is separated from the surface of the table T while being suspended by screws 5. In the case of the cover-shaped stand 2, its volume is set in advance so that the space defined by the surface of the table T and the inner surface of the stand 2 is a space that resonates with the sound when the phosphorus 4 is hit. Is formed.

The time display section 1a stands upright in a slightly higher or lower position than in the vertical direction so that the time can be easily viewed. Therefore,
When the set time of the alarm matches the current time, the motor 6
A drive signal is supplied to a, and the phosphorus 4 is hit by the hit ball 6c, and an alarm sound is generated by the hitting sound of phosphorus. This alarm sound resonates in the space between the surface of the table T and the inner surface of the stand portion 2 and becomes a loud alarm sound.

FIG. 3 shows another embodiment, in which a stand 12 has a sound emission hole 12 for emitting a sound from the phosphorus 4.
a is formed in a slit shape. Other portions substantially the same as those in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted. By providing the sound emission hole 12a, the alarm sound can be further increased.

FIGS. 4 and 5 show still another embodiment, in which the stand 22 has a band shape. Drive 2
Reference numeral 6 is provided on the timepiece main body 1 side. The driving device 26 has the same configuration as the driving device 6 described above, but is illustrated by a block-like schematic line. In the case of the timepiece body 1, a window hole (not shown) for exposing the ball of the driving device 26 to strike the phosphorus 4 is formed. Other portions substantially the same as those in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted.

With such a configuration, when the portable device is carried, as shown in FIG. 4B, when the stand portion 22 is rotated about the hinge 3, the phosphorus 4 covers the time display portion 1a. As in the case of 1, the shape becomes compact and suitable for carrying. Further, in this portable state, the driving device 26 does not come into contact with the phosphorus 4, so that no alarm sound is generated carelessly without stopping the sound.

When a timepiece is used, as shown in FIG. 4A, the stand 22 is rotated about the hinge 3, the phosphorus 4 is moved away from the time display 1a, and placed on the table T. I do. The hinge 3 and the stand 22 are provided on the surface of the table T.
The phosphorus 4 is separated from the surface of the table T while being suspended from the screw 5.

When the set time of the alarm coincides with the current time, the driving device 26 is driven to rotate the hitting ball and strike the phosphorus 4 in the window of the watch body 1 to emit an alarm sound.
In this case, the emission of the alarm sound is not hindered because the phosphorus is exposed, and a loud alarm sound is emitted because the table T serves as a resonance plate.

In the embodiment shown in FIG. 1 or FIG. 3, the driving device may be provided on the main body of the timepiece as in the case of FIG. Although not shown, the driving device may be configured by directly attaching a piezoelectric element to phosphorus. In this case, as in the case shown in FIG. 4, the table T serves as a resonance plate and can emit a loud alarm sound.

[0020]

According to the present invention, the timepiece body and the stand are hingedly connected to each other, and a phosphorus large enough to cover the time display is fixed to the stand, and a driving device for striking the phosphorus is provided. , A loud alarm sound can be generated, and when carrying, Lin covers and covers the time display,
A small and safe timepiece can be provided as in the past. Since the sound emitting hole is formed in the stand portion, and the stand portion is band-shaped to expose the phosphorus, there is an effect of improving the sound pressure of the alarm sound.

Since the driving device is disposed in the space outside the phosphorus of the stand, space efficiency can be improved. In addition, since the driving device is disposed on the timepiece main body side and utilizes the gap on the main body side, the space efficiency can be similarly improved, and in this case, phosphorus is not struck when the device is carried,
The effect of stopping the sound can be improved without the need for the means for stopping the sound. Furthermore, since the piezoelectric element is attached to the phosphorus as a driving device, the configuration is simplified, and since the alarm sound is generated by phosphorus, a large alarm sound can be generated.
