Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch device such as an alarm clock.

[0002]

2. Description of the Related Art Generally, in a clock such as an alarm clock, a sound source such as a speaker or a buzzer emits an alarm sound such as a voice or a melody at a desired wake-up time, or notifies a time signal. Equipped with a notification device. Also, an alarm switch is usually provided, and the alarm switch can be turned off in order to prevent various sounds from being emitted from the sound source when the alarm device is activated due to time-up when it is not necessary, such as during absence. It is like this. For example, the actual exploitation 55-14
As disclosed in Japanese Patent No. 593, a watch body is provided with holes or windows for emitting a notification sound from a sound source such as a speaker or an electronic buzzer. Sound is emitted when an alarm switch is set to ON. Shutter-shaped sound source on /
It is known that an off switch is used to adjust the volume by opening and closing the volume, or to stop the notification sound when the sound output hole is completely closed.

[0003]

By the way, like the device of the above publication, when the alarm switch is in the ON state,
The following problems remain as points to be improved in the structure in which the operation of the shutter-type switch is interlocked with ON / OFF of the sound source. That is, since the operation of the shutter-type switch is linearly performed in a vertical or horizontal wide area plane including the sound output hole, there is a troublesome manual operation between turning on and off the sound source. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a timepiece switch device in which the operability in stopping the sound emission from a sound source is improved conveniently.

[0004]

In order to achieve the above object, a switch device of a timepiece according to the present invention is formed in a substantially spherical shape on the upper side excluding the front surface having a time display portion, and is provided on the upper portion of the spherical shape. A main body in which the first sound source is built in facing the sound emission hole, and an upper portion which is formed in an arch shape that can be rotated from the outside along a spherical surface extending from the upper part to the lower part of the main body to close the sound emission hole. Turn off the first sound source at the position,
A movable switch member that turns on the first sound source is provided in the spherical rotation section to the lower position. In the present invention, both ends of the arch-shaped movable switch member can be rotatably supported by the main body. Further, in the present invention, it is possible to further include a second sound source, and it is possible to provide a switching means for switching the operation of the first sound source and the second sound source by opening and closing the sound output hole by the movable switch member. The switch structure for a timepiece according to claim 1, which has. Furthermore, in the present invention, a rib extending at a predetermined angle with respect to the rotation direction is provided on the inner surface of the movable switch member, and a switch for turning on / off the first sound source by moving by the angular displacement guided by the rib is provided. It can be provided on the main body.

[0005]

Since the arch-shaped both ends of the movable switch member are rotatably supported by the main body, the on / off operation of the sound emission from the first sound source by the speaker or the like becomes the off position of the spherical upper part of the main body. It is possible to smoothly perform the one-touch operation using the spherical surface between the ON section excluding this position. In particular, when returning from the upper off position to the on section, the weight of the movable switch member slipping on the spherical surface of the main body can be returned quickly due to its own weight. Since the sound emitted from the first sound source by the speaker or the like has a relatively high volume, even when the sound emission from the first sound source is stopped by closing the sound emission hole by the movable switch member, the second sound is emitted by the electronic buzzer or the like. The sound source can be activated. Also,
The rotation of the movable switch member can be converted into the movement of the switch such as a slide switch in the on / off direction by the angular displacement of the rib.

More specifically, this alarm clock is a combination of a substantially spherical main body 1 and an arch-shaped movable switch member 40, such as headgear worn in sports competitions such as football where the user's preference is enhanced. A helmet is modeled. The main body 1 includes a spherically-shaped upper case 20 and a lower case 30 that also serves as a bottom plate.
It is a combination of and, and a display part 2 for displaying the current time and alarm time digitally and related items is provided on the almost flat front part, and an internal time signal or alarm sound is issued to inform the user. In addition, an electric circuit for driving the display unit 2 and related devices are stored. Also,
A sound emitting hole 21 for emitting a notification sound is provided on the upper spherical surface of the upper case 20, and a first sound source for emitting a buzzer sound, a voice, or a melody notification sound at a position facing the sound emission hole 21. The speaker 3 is arranged.

The movable switch member 40 is provided as a switch for turning on / off the operation of the sound source speaker 3 in the embodiment, and is formed in an arch shape having substantially the same curvature so as to be rotatable along the spherical surface of the upper case 20 of the main body 1. Both ends of the arch are rotatably supported by the support portion 22 of the upper case 20. As shown in FIG. 2, the movable switch member 40 has an on-section from an upper off position abutting the abutting step 23 on the upper case 20 side to a lower abutting step 23 excluding the upper off position. It can be moved by turning. As is apparent from FIG. 3, the rotating operation of the movable switch member 40 is manually performed by the user himself, and a pair of left and right protrusions 41, 41 provided on the back surface are provided on the upper case 20 to form a pair of parallel two pieces. The guide grooves 25, 25 are engaged to guide the rotation. Further, on the upper surface of the movable switch member 40, streaks 42 having irregularities are alternately engraved for the purpose of preventing slippage during the turning operation.

Both end portions of the arch-shaped movable switch member 40 are supported by the support portion 22 of the upper case 20 as shown in the sectional view of FIG. 1 and the side sectional view of FIG.
The left and right end bottom surfaces 43 of the movable switch member 40 are provided with curved guide ribs 26 on the support portion 22 of the upper case 20.
Is slidably abutted from above, and the locking claw portion 44 extending from the end bottom surface 43 is slidably engaged with the upper edge portion 27 of the support portion 22 from the inside. In the curved guide rib 26 provided on the support portion 22 side, the stopper end portion 26a provided at the lowermost end of the curved guide rib 26 is provided at the abutting step portion 23 at the lower on position, and the stopper end portion 26b provided at the uppermost end is provided at the upper off position. The abutting step portions 24 are made to correspond to each other. An alarm electric circuit is configured so that the operation of the movable switch member 40 is interlocked with ON / OFF of the alarm switch 4 described below. In addition, in order to give a click feeling that clearly indicates the end of operation of the movable switch member 40 at the lower on position and the upper off position, it is necessary to provide the concave portion and the convex portion at the sliding points so as to engage and disengage. You can also

Similarly, in the sectional view of FIG. 1 and the side sectional view of FIG. 4, a contact terminal 11 such as a leaf spring is arranged on the upper surface of the printed wiring board 10 arranged inside the main body 1. The movable switch member 40 is attached to the contact terminal 11.
The rotation allows the locking claw portion 44 at the base end to be engaged and disengaged by utilizing elasticity. That is, in the state where the movable switch member 40 shown by the phantom line in FIG. 4 is at the upper off position and the locking claw portion 44 is in contact with the contact terminal 11, the speaker electric circuit is turned off and the first state is set. The sound emission from the speaker 3 of the sound source is stopped. On the other hand, in the rotation section where the movable switch member 40 is separated from the upper off position to the lower position (abutting step portion 23), the locking claw portion 4 is provided.
When 4 is disconnected from the contact terminal 11, the speaker electric circuit can be turned on and sound can be emitted when the time is up.

On the other hand, when the alarm switch 4 provided on the display unit 2 is set to the "ON" state, the speaker electric circuit is started to the ON state, and the speaker is set by the timer set to the desired time. Sound can be emitted from 3. Therefore, for example, in a case where it is not necessary to emit the notification sound after absent for a long time, if the alarm switch 4 is set to the “off” state, the sound source speaker 3 does not emit the sound even when the time is up. As shown in the bottom view of FIG. 5, in the lower case 30 of the main body, a battery battery 6 for power supply of an electric circuit including the sound source speaker 3, an alarm time feed (+) button 7, an alarm time return (-) button. 8, and operation devices such as a current time setting button 9 are arranged.

In addition to the above configuration, in the embodiment, a snooze button 13 having a function of sounding an alarm sound at regular intervals can be installed on the upper front side of the upper case 20, and the function is an alarm switch. It can be canceled by turning off 4. In addition, a lighting light 14 can be installed in combination with the snooze button 13, and lights (not shown) provided on the display unit 2 can be lit for a certain period of time during a period other than the alarm sounding time. Can be blinked.

Next, the operation mode and operation of the above embodiment will be described. The user operates the alarm time feed (+) button 7, the alarm time return (-) button 8, the current time setting button 9, etc. to set the alarm switch 4 to the ON position and then the desired time. The speaker 3 is set to emit a notification sound at the notification time. At this time,
As described above, the movable switch member 40 is in the lowermost ON position and is in the standby position by abutting against the abutting step 23 on the upper case 20 side and the stopper end 26a of the guide rib 26.

When the set notification time is up, the speaker electric circuit is turned on and a notification sound is emitted through the speaker 3. This notification sound is emitted to the outside through the sound emission hole 21 opened in the upper case 20. When the user wants to stop the sound output because the notification is sufficient, the movable switch member 40 is manually operated to pull up the section from the lower ON position of FIG. 4 to the upper OFF position of FIG. . By pulling up the movable switch member 40, the opening area of the sound output hole 21 is narrowed, and the volume is correspondingly reduced to be small.

When the movable switch member 40 is pulled up to the upper off position shown in FIG. 2 and the sound output hole 21 is completely closed, the locking claw portion 44 at the proximal end side of the movable switch member 40 is inside the main body. Printed wiring board 10 contact terminal 11
Press while making contact. During this time, the movable switch member 40
In the pulling operation in the section by the arc motion of, the both ends are rotatably supported by the support portion 22 of the upper case 20, and smoothly guided by the spherical surface of the upper case 20 with almost one-touch. Done. By the contact with the contact terminal 11, the speaker electric circuit is turned off and the ringing of the speaker 3 is stopped.

In the first embodiment, the support structure at both ends of the movable switch member 40 shown in the cross section of FIG. 1 can be modified as shown in FIGS. The bottom surface 43 of the end portion of the movable switch member 40 is guided and slides on the curved surface of the guide rib 26 of the upper case 20.
8 is integrally molded, and the printed wiring board 10 is provided with screws 29.
By fixing the support portion 22 on the upper side, the rigidity of the support portion 22 can be increased. Corresponding to this, by forming a retaining rib 45 from the inside in the vicinity of the end bottom surface 43 of the movable switch member 40 as shown in the figure, the movable switch member 40 is formed.
When an external force is applied from the outside, the retaining rib 45 abuts the upper case 20 and functions as an abutting stopper, which can strengthen the disassembly of the main body due to an accidental drop or the like.

Further, as a modified example, instead of the contact terminal 11 by the leaf spring shown in FIGS. 1 and 4 of the first embodiment, as shown in FIG. 6, a tumbler and a micro switch 15 are printed wiring. It can also be provided on the substrate 10.

Similarly, as a modified example, when the micro switch 15 is used, the noise prevention plate 16 also shown in FIGS. 9 and 10 also serving as a blind is effective. Until now, non-woven fabrics have been used for this type of noise suppression member,
There were problems such as durability and deformation, and the switching knob could not be enlarged. Such a problem can be solved by using the resinous noise prevention plate 16 having a shape in which the locking claws 16a are provided at four corners as shown in the drawing, and by locking and mounting on the case side using resin elasticity.

Further, as shown in FIG. 3 again, as a modification, an electronic buzzer 5 of the second sound source according to the present invention may be provided and the following settings may be made. Speaker 3 of the first sound source
The sound emitted from is relatively loud. When the movable switch member 40 is pulled up to the upper off position to close the sound output hole 21, the sound output from the speaker 3 is stopped. At this time, it is also possible to cause only the electronic buzzer 5 to sound in a relatively small sound, and subsequently to emit the notification sound. When the alarm switch 4 is set to the off state, not only the sound from the speaker 3 but also the electronic buzzer 5 does not ring. The switching means for switching between the operation of the first sound source and the operation of the second sound source can be easily configured on an electric circuit.

Although the first embodiment and its modification have been described above, FIGS. 11 to 13 show a second embodiment of the present invention. The second embodiment has a structure in which a slide type switch 17 is used in place of the contact terminal 11 and the micro switch 15 which are the leaf springs of the first embodiment. As is clear from the drawing, a movable switch member 50 having substantially the same shape as the movable switch member 40 of the first embodiment is arranged, and a pair of left and right movable switch members 50 are formed on the inner sliding surface side thereof at an angle slightly oblique to the moving direction. Long ribs 51, 51 are provided, and the pair of left and right ribs 5 is provided.
The slide knob 18 of the slide switch 17 is sandwiched between 1 and 51. Other,
The members corresponding to those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

Therefore, in the second embodiment, the ribs 51, 51 are displaced in accordance with the rotation of the movable switch member 50, and the sliding switch 17 is provided with a forcing force for moving a distance corresponding to an angular displacement which is obliquely displaced. Work on the slide knob 18.
By moving the slide knob 18 in the left-right direction in FIG. 11, the speaker electric circuit can be turned on / off by the amount of movement.

[0022]

As described above, according to the timepiece switch device of the present invention, when the movement of the movable switch member is interlocked with the electric circuit for turning on / off the sound emission by the sound source speaker or the like, the weight of the movable switch member is reduced. Smooth one-touch operation is possible by utilizing the spherical rotation of the body.
