[Prior Art]

 FIG. 1 shows a perspective view of a conventional battery-powered alarm clock 10. A conventional alarm clock 10 is equipped with a dial 11 having a number of 12 hours. The hour hand 12 and the minute hand 13 are arranged on the dial 11 so as to display the time. Further, the alarm hand 14 is arranged on the dial 11 so as to display a preset time for the alarm clock 10 to give an alarm. The alarm clock 10 further includes an alarm switch 15 that can be turned on or off. Then, when the alarm switch 15 is in the ON state, the alarm clock 10 issues an alarm whenever the hour hand 12 is overlaid on the alarm hand 14. At this time, the user turns off the alarm switch 15 to stop the alarm. Otherwise, the alarm bell will continue to ring for about 40 minutes. The length of time this alarm bell continues to ring is predetermined by the manufacturer's design.

As shown in FIG. 2, the time mechanism of the conventional alarm clock 10 includes an alarm hand 14, an hour hand 12, and a minute hand 13 which are ends of a first shaft 17, a second shaft 18, and a third shaft 19. It is attached to each section. The first shaft 17, the second shaft 18, and the third shaft 19 are arranged concentrically, and the other end of these shafts has an alarm gear 24, an hour gear 22, and a gear wheel 23. And are fixed respectively. Therefore, the rotation of the hour gear 22 drives the rotation of the hour hand 12, the rotation of the minute gear 23 drives the rotation of the minute hand 13, and the rotation of the alarm gear 24 drives the rotation of the alarm hand 14. The hour gear 22 and the minute gear 23 mesh with other gears, and the time device (not shown) is configured so that the hour gear 22 makes one rotation every 12 hours and the minute gear 23 makes one rotation per hour. There is. The alarm gear 24 can be rotated by the user turning an alarm knob (not shown) arranged behind the alarm clock 10. The alarm hand 14 rotates once on the dial 11 when the alarm gear 24 makes one rotation. The first metal contact 27 is arranged on the hour wheel 22 and the second metal contact 28 is arranged on the alarm gear 24 (the specific structure for the two metal contacts to be in contact with each other is complicated. However, in the drawings, a simplified structure is used for easy understanding). Whenever the hour hand 12 appears to be overlaid on the alarm hand 14, the first metal contact 27 also comes into contact with the second metal contact 28, thereby electrically connecting both contacts.

In FIG. 3, switches-1 and 32 are switches corresponding to the metal contacts 27 and 28, and switches-2 and 33 are switches corresponding to the manually operated alarm switch 15. Therefore, if the alarm switch 15 is turned on in advance and the first metal contact 27 and the second metal contact 28 come into contact with each other, the current from the battery 31 flows to the alarm bell 34 and an alarm is generated. It begins to ring. The contact time of the two metal contacts 27, 28 can be predetermined arbitrarily, but typically the alarm will sound for 40 minutes, which is believed to be long enough to wake a person sleeping deeply. Is designed.

A drawback of the conventional alarm clock 10 is that, for example, the user presets a desired wake-up time every morning on a weekday and switches the alarm switch 15 so as to return to the ON state the night before going to bed. Caused by forgetting. As a result, the alarm clock alarm may not ring next morning and may be late for school or important meetings.

Therefore, there is a need for an alarm clock capable of sounding an alarm at the same time every morning so as to wake up the user without requiring the operation of switching the alarm switch 15 to the ON state every night before going to bed. To do.

[0007]

[Problems to be solved by the device]

 Therefore, the main purpose of the present invention is that the alarm clock automatically alarms once every 24 hours at the same time every day, even if the alarm switch is not turned on every day after the specific alarm time is preset. It is to provide an alarm bell control for use against a conventional alarm clock with a 12-hour number dial to allow it to ring.

Another object of the present invention is to provide a switch to an alarm bell controller that is convertible to allow the alarm clock to operate in the same manner as a normal alarm clock.

The alarm bell control device according to the present invention comprises the first switch and the second switch which are alternately switched in the time zone of 12 hours at the time when the hour hand is overlapped with the alarm hand. There is. The third switch is connected between the first switch and the alarm bell and corresponds to a manually operable alarm switch of a normal alarm clock. The actuator is coupled to the third switch and is capable of turning the third switch on when electricity is applied to the actuator. The fourth switch is coupled between the second switch and the actuator and the on / off state of the fourth switch is opposite to the on / off state of the third switch.

The alarm bell control device further includes a two-way switch that can select whether to couple the second switch to the third switch or to couple the second switch to the fourth switch. .. If the second switch is connected to the third switch, the alarm clock using the present invention operates in the same manner as a normal alarm clock, and if the second switch is connected to the fourth switch, the present invention is used. The alarm clock sounds an alarm every 24 hours at a preset time without the need to manually further adjust the alarm switch to the on state every day.

Hereinafter, the present invention will be further clarified by the detailed description of the embodiments of the present invention with reference to the accompanying drawings.

【Example】

 The present invention includes several improvements over conventional alarm clocks. Therefore, the parts of the most preferred embodiment of the present invention are designated by the same reference numerals as the conventional parts of FIGS. Also, while the preferred embodiment of the present invention may be described as being configured with an alarm clock of a particular construction, the essence of the present invention is applicable to other alarm clocks of any construction and type. It should be understood throughout the description of the invention. Therefore, many various structural modifications are possible in the present invention, and the following detailed description of the most desirable embodiments does not limit the scope of the present invention.

FIG. 5 shows an ideal new alarm clock 10 ′ with the necessary improvements over the conventional alarm clock 10. In the alarm clock 10 'of this embodiment, a new switch 16 which can be manually operated and adjusted is added. When this switch 16 is in the first position, indicated by "manual (12)", (this "12" indicates that the alarm clock 10 'can alarm once every 12 hours) Is the same as the conventional alarm clock 10 shown in FIG. However, when switch 16 is in the second position, as indicated by "auto (24)" (where "24" indicates that alarm clock 10 'can alarm once every 24 hours), alarm clock 10 'Is capable of automatically issuing an alarm every 24 hours without having to manually turn on the alarm switch 15 after a specific wake-up time has been preset.

Referring to FIG. 6 with reference to FIG. 2, two large gears 61 and 63 are meshed with the hour gear 22. The radii of the gears 61, 63 are exactly twice the radius of the hour gear 22. The other two large gears 62 and 64 are also meshed with the alarm gear 24, and their radius is also twice the radius of the alarm gear 24. The hour gear 22 makes one revolution every 12 hours. This action is the same for the alarm gear 24. In the following description, the gears 61 and 62 are both called the "first timing unit 81", and the gears 63 and 64 are both called the "second timing unit 82". The third metal contact 71 and the fourth metal contact 72 are arranged on the gears 61 and 62, respectively. The fifth metal contact 73 and the sixth metal contact 74 are arranged on the gears 63 and 64, respectively. Assuming that two polar coordinate systems are drawn on gear sets 61, 62 and gear sets 63, 64 with their origins located on their axes, the third metal contact 71 and the fifth metal contact 73 are , It may be said that they are in phase, ie always in the same polar angle, and that the polar angles directed to the fourth metal contact 72 and the sixth metal contact 74 always differ in phase by 180 °. May be. This arrangement causes the metal contacts 71, 72 on the gears 61, 62 to contact each other every 24 hours at the time indicated by the alarm hand 14, at which time the metal contacts 71, 72 are contacted. It is 12 hours from the time of contact. The contact duration between the metal contacts 71 and 72 and between the metal contacts 73 and 74 is set to 40 minutes as usual.

In FIG. 7, a schematic circuit diagram embodying the concept of the invention is shown. Reference numerals 81 and 82 in FIG. 7 indicate the first timing unit and the second timing unit, respectively. The on and off states of the switches 83 and 84 are controlled by the timing units 81 and 82, respectively, and therefore, at the time indicated by the alarm hand 14, the switches are alternately engaged every 12 hours. Become.

The third switch 85 is connected to the alarm bell 34 and can be manually operated like the alarm switch 15 shown in FIG. The operating device 88 is coupled to the third switch 85, and when the current from the battery 31 flows to the operating device 88, the third switch 85 can be turned on. The fourth switch 87 is connected to the actuator 88, and its on / off state is opposite to the on / off state of the third switch 85. Specifically, when the third switch 85 is on. The fourth switch 87 is off, and when the third switch 85 is off, the fourth switch 87 is on.

The circuit diagram of FIG. 7 further includes a two-way switch 86 embodying the switch 16 shown in FIG. The two-way switch 86 can be switched to either mode 1 “manual (12) mode” or mode 2 “automatic (24) mode”.

“Manual (12) mode” When the two-way switch 86 is switched to the mode 1 “manual (12) mode” and the third switch 85 is manually operated to be in the on state, the hour hand 12 is the alarm hand. When the metal contacts 71, 72 on the gears 61, 62 constituting the first timing unit 81 come into contact with each other when they are overlapped with each other, the first switch 83 is turned on by the generated trigger signal. Further, when the metal contacts 73, 74 on the gears 63, 64 forming the second timing unit 82 come into contact with each other, the second switch 84 is turned on by the generated trigger signal. Thus, when the hour hand 12 overlaps the alarm hand 14, either the first switch 83 or the second switch 84 is turned on. When the first switch 83 is on, current flows from the battery 31 through the first switch 83 and the third switch 85 to the bell 34. When the second switch 84 is on, current flows from the battery 31 to the bell 34 through the second switch 84, the two-way switch 86, and the third switch 85. Thus, in this manner, current can flow to bell 34 regardless of whether first switch 83 or second switch 84 is turned on. Therefore, the operation of the alarm clock 10 'is exactly the same as that of the normal alarm clock 10 and the alarm bell 34 can give an alarm once every 12 hours.

“Manual (24) mode” When the two-way switch 86 is switched to mode 2 “automatic (24) mode”, the alarm clock 10 ′ needs to manually operate the alarm switch to the ON state every time. Without, the alarm will be automatically issued once every 24 hours at the same preset time. For example, if the user wants to wake up at 6:00 am (6:00 am) every day from the next day, the user first switches the two-way switch to mode 2 "auto (24) mode" and then the third. The switch 85 is turned on. Next, the user turns the alarm hand 14 clockwise until the alarm bell 34 rings (the alarm hand 14 overlaps the hour hand 12) and then continues turning the alarm hand 14 until a desired wake-up time, that is, 6:00 AM. .. If the wake-up time is 12 hours or more and 24 hours or less after the preset time (this embodiment may be rare), the alarm hand 14 passes the hour hand once at 12:00 until the desired wake-up time (alarm is , It doesn't ring at this time) It doesn't ring unless it is turned. This order ensures that the first switch 83, rather than the second switch 84, will be engaged when the hour hand 12 reaches the first wake up time.

In another preferred embodiment of the present invention, the dial 11 of the alarm clock 10 'according to the present invention may include two AM-PM display devices (not shown). One display device is associated with the hour hand 12 and the other display device is associated with the alarm hand 14. The installation of the AM-PM indicator can facilitate the user to set the correct wake-up time under the automatic (24) mode.

At 6:00 AM on the next day, the hour hand 12 overlaps with the alarm hand 14, and the trigger signal generated by the contact between the contacts 71 1 and 72 causes the first switch 83 to be turned on. Then, the current from the battery 31 flows through the first switch 83 and the third switch 85 to the alarm bell 34. When the alarm is sounding, the user may turn off the alarm by switching the third switch 85 to the off state, or the user may be shut off by releasing the first switch 83 after a predetermined 40 minutes. The alarm bell 34 may be kept ringing until then.

If the third switch 85 continues to be in the ON state, the fourth switch 87 remains in the OFF state. Therefore, at 6:00 PM on the same day, even if the second switch 84 is turned on by the trigger signal generated by the contact between the contacts 73 and 74, electricity does not flow to the actuator 88 and the switch 85 is turned on. Do not do unnecessary things to switch to. Also, current can flow to the bell 34 when the first switch 83 is engaged at 6:00 AM the next morning. On the other hand, if the user turns off the third switch 85 to stop the alarm after getting out of bed, the fourth switch 87 will be turned on by the reverse relationship of the third switch 85. Has been converted. Therefore, at 6:00 PM on the same day, the current from the battery 31 is flowing to the actuator 88 through the second switch 84, the two-way switch 86, and the fourth switch 87. This causes the actuation device 88 to return the third switch 85 to the on state as if current had flowed through the alarm bell 34 when the first switch 83 1 was reengaged at 6:00 AM the next day. Therefore, the fourth switch 87 returns to the off state and no current flows to the bell 34.

On weekends, if the user wishes to sleep until late in the morning, he switches the switch 16 to the manual (12) mode the previous night to switch the alarm switch 15 to the off state. However, before going to bed on Sunday night, the user must switch the switch 16 back to the automatic (24) mode, turn on the alarm switch 15 and reset the wake-up time.

Specific structures of the fourth switch 87 and the actuator 88 will be described below. The structure may be made by modifying the alarm switch 15 of a conventional alarm clock 10.

FIGS. 4A and 4B show the structure of one type of alarm switch 15 that is normally manufactured in Japan. The alarm switch 15 can be fixed in the lower position when pressed once and released to return to the original upper position when pressed again. The alarm switch 15 includes a button 40, a body portion 41, a pivot member 42 pivotally coupled to the body portion 41 by a pivot joint 43, a heart-shaped groove 45, a spring 46, and a switch 48. There is. The protrusion 44 is provided on the turning member 42 and fits in the heart-shaped groove 45. An enlarged view of the heart-shaped groove 45 is shown separately in FIG. 4C, said groove 45 being a projection when the button 40 is pushed from a high position as shown in FIG. 4A to a low position as shown in FIG. 4B. As shown in FIG. 4C, 44 moves from the position A of the heart-shaped groove 45 to the position C through the position B, and is held by the protrusion 44 so that the button 40 is released from the lower position to the higher position again. When pushed, the protrusion 44 is configured to move from the position C to the position D and back to the position A (the alarm clock shown here is a conventional one, and therefore, the present invention). It's not within the spirit of, so I won't explain it in detail). The notch 47 pushes the switch 48 from position E to position F when the button 40 is pushed downward to move the body 41, and when the button 40 is released, the switch 48 is pushed. It is provided on the body 41 in such a manner that it returns to position E by means of an elastic device (not shown) provided on it. The switch 48 corresponds to the switch-2 (33) shown in FIG. 3, the conversion to the position E corresponds to the conversion to the ON state, and the conversion to the position F corresponds to the conversion to the OFF state. ..

Referring to FIGS. 8A and 8B, there are shown some improvements made to the conventional alarm switch 15 shown in FIG. 4A, the improved alarm switch 15 ′ being the second timing unit 82 of FIG. It is possible to automatically jump back from a lower position to a higher position when motivated by.

The alarm switch 15 ′ further includes a switch 91 that embodies the fourth switch 87 shown in FIG. 7. The cutout 92 is provided in the body 41 to control the switch 91. The switch 91 is provided in such a manner that pushing it to the right corresponds to turning it on. This effect is opposite to that of the switch 48, so that the ON and OFF states of the switches 48 and 91 are opposite to each other.

Referring to the side views shown in FIGS. 9A and 9B, the protrusion 49 at the center of the heart-shaped groove 45 shown in FIG. 4C has been transformed to allow the improved protrusion 49 'to be retracted. The solenoid 93 is provided behind the heart-shaped groove 45. If the protrusion 44 of the swivel member 42 is installed at the position C, the solenoid 93 jumps from the position C to the position A, which causes the button 40 to return to the higher position. Can be attracted to. When the button 40 jumps back to the high position, the switch 91 also jumps back to the left, thus interrupting the current flowing through the solenoid 93 and thus releasing the attracted protrusion 49 '. .. Next, the protrusion 49 'jumps back to the right by a pair of elastic plates 94 fixed to it.

Alarm switches in other manufactures of alarm clocks may differ from the alarm switch 15 'described above. Therefore, a different structure than that described above may be proposed to be provided in the alarm switch. However, even for the same alarm switch 15 ', the fourth switch 87 and the actuator 88 may have numerous other modifications. Therefore, it should be understood that the present invention is not necessarily limited to the described embodiments. On the contrary, the intention is to cover various modifications and similar arrangements included within the spirit and scope of the claimed utility model claims. The scope of the claims should be accorded the broadest interpretation so as to encompass all the modifications and similar structures.
