Description

[Detailed description of the invention] The present invention is a clock switch device that is most suitable for application to a world clock, for example, and can be applied to any region by selectively switching multiple switches corresponding to multiple regions. This invention relates to displaying a corresponding time on a time display section.

The world clock allows you to know the time in various parts of the world (for example, Tokyo, New York, London, etc.) just by switching the above switches, and if you carry it with you when traveling around the world, you can This is very convenient as it allows you to know the time at each place where the watch is used by simply switching the switch corresponding to the place where the watch is used.

However, on the other hand, since the time in each location is displayed simply by switching the switch, it is difficult to determine whether the currently displayed time is actually the time in the location where the watch is currently being used. , it is difficult to easily tell just by looking at the time display. In particular, in this type of clock device, the time display section must be as large as possible to make it easy to read the time, and the time display section is very expensive (especially liquid crystal displays are expensive). Because it has one display section and is configured to display the time of many regions on that one time display section,
The above discrimination is even more difficult.

Therefore, when using this type of clock switch device, it is necessary to always check which region the time displayed on the time display actually corresponds to. Otherwise, the displayed time is often not the time in the area where the watch is actually used, and the displayed time is often the time in the area where the watch is used. There is a serious risk of misunderstanding this and making various mistakes due to the time difference.

The present invention has been devised in view of the above-mentioned circumstances, and although it is possible to freely display the time corresponding to any region by selectively switching the plurality of switches, it is difficult to switch between the switches. After the operation, the time corresponding to a specific region, such as the region where the clock is used, can be displayed without fail.
The object is to provide something that can prevent serious mistakes caused by the time difference mentioned above.

An embodiment in which the present invention is applied to a world clock will be described below with reference to the drawings.

First, the overall structure will be explained with reference to FIGS. 1 to 4. For example, a world map 2 is displayed on the front of the housing 1. Further, a time display section 3 is provided on a part of the front surface of the casing 1.

On the other hand, two openings 5 and 6, front and rear, separated by a partition 4 are provided on the upper surface of the housing 1. The front opening 5 is provided with a plurality of switches 7a, 7b, . . . , 7n corresponding to a plurality of regions (for example, Tokyo, New York, London, etc.). Note that these switches 7a, 7b...7n are configured, for example, as push button switches, and if one of these switches 7a, 7b...7n is pressed and the other switch is pressed, the switch that was pressed first will be pressed. The switch is configured as an interlocking push button switch that releases the lock of the switch and automatically returns the switch. Further, these switches 7a, 7b, . . . , 7n are arranged in a horizontal line corresponding to each region displayed on the world map 2, for example. Further, the rear opening 6 is provided with, for example, a power switch 8, a time adjustment knob 9, an alarm set knob 10, an alarm stop switch 11, and other necessary parts.

Further, a lid 13 that can be opened and closed is provided at the top of the housing 1. For example, the lid 13 is rotatably supported at both ends of the housing 1 on the partition portion 4 via a pair of fulcrum pins 14 . When the lid body 13 is rotated forward about the fulcrum pin 14 and laid down horizontally as shown by the solid line in FIG.
It is configured so that it can be closed at the upper position of 7b...7n. In this closed state, for example, an elastic lock claw 15 provided on the lid 13 is elastically engaged with a protrusion 16 provided on the housing 1, and the lid 13 is locked. ing. Then, when the lock is released and the lid body 13 is rotated rearward about the fulcrum pin 14 as shown by the chain line in FIG. 4, the front opening 5 is opened and the switches 7a, 7b, . . . 7n becomes operable. At this time, switch and knob 8~
Class 11 will be closed by the lid 13.

And this lid body 13 has a fourth
When the switch 7 is closed as shown by the solid line in the figure,
A switch operating means 18 is provided which allows the time display section 3 to display the time corresponding to the specific area by pressing a switch corresponding to a specific area among the areas a, 7b, . . . , 7n.

Although various structures are conceivable for this switch operation means 18, one example is shown here.
That is, this switch operation means 18 is composed of a push button section 19 which is an operation section, a knob section 20 for sliding operation, and a connecting section 21 that connects these two. On the other hand, the lid body 13 has the switches 7a, 7
A long hole 22 is formed along b...7n. The switch operating means 18 is connected to the connecting portion 21.
The part is inserted into the elongated hole 22, and the elongated hole 22
It is configured to be slidable and adjustable along the By sliding the switch operating means 18 along the elongated hole 22, the push button portion 19 can be slid along the switches 7a, 7b, . . . , 7n. At this time, the sliding movement of the switch operating means 18 corresponding to the elongated hole 22 may be made a little stiffer, or the switch operating means 18 may be moved to the cover 13 at a position where the push button portion 19 faces each switch 7a, 7b...7n. It is convenient if the positioning is performed by clicking on the object.

The world clock constructed as described above is normally used with the lid 13 closed as shown by the solid line in FIG. At this time, the rear opening 6 is opened, and the switches and knobs 8 to 11 can be operated.

When the user wants to know the time in any part of the world (for example, Tokyo, New York, London, etc.), the lid 13 is opened as shown by the chain line in FIG. As a result, the front opening 5 is opened and the switches 7a,
7b...7n become operable. At this time, the switches and knobs 8 to 11 are closed off by the lid 13, making these operations impossible. Then, when the switch 7a, 7b, . . . , 7n corresponding to the desired region is selectively pressed as shown by the chain line in FIG.

Then, when the rear lid body 13 is closed again as shown by the solid line in FIG. 4, the push button 19 of the switch operating means 18 is pressed to one of the switches 7a, 7b...7n as shown in FIGS. 3 and 4. It touches me and I press it. As a result, the time in the area corresponding to the pressed switch is displayed on the time display section 3.

Therefore, among the switches 7a, 7b...7n, for example, the switch corresponding to a specific region such as the area where the clock is used, that is, the switch corresponding to Tokyo if used in Tokyo, and the switch corresponding to New York if used in New York. Alternatively, if the switch is to be used in London, the switch operating means 18 may be slid in advance along the elongated hole 22 to a position corresponding to a switch corresponding to a specific area, such as a switch corresponding to London. Then, the lid 13 is closed as described above.

As a result, the push button portion 1 of the switch operating means 18
When the switch 9 is brought into contact with the switch corresponding to the above-mentioned specific area and pressed, the time of the area corresponding to the specific switch will be displayed on the time display section 3.

As described above, by opening the lid 13, the switches 7a, 7b, . Therefore, there is no possibility that the time displayed on the time display section 3 will be different from the time in the area where the watch is actually used. Various mistakes caused by time differences can be prevented.

Also, as long as the lid 13 is closed, the time of the region where the watch is used will always be displayed on the time display section 3, so the knob 9,
10 etc., operations such as time adjustment and alarm setting can be performed with peace of mind at all times.

In the above embodiment, the switch operating means 18 is
This is configured so that it can be moved and adjusted along the elongated hole 22, but it can also be adjusted by using the switch 7, for example.
A, 7b...7n, respectively, are provided with a plurality of switch operation means on the lid 13, and by selectively switching these, when the lid 13 is closed, only the switches corresponding to a specific region are activated. It is also possible to make it possible to operate. Further, the switches 7a, 7b, . . . , 7n are not limited to push button switches, and may be, for example, touch switches or waveform switches.

Next, an example of the circuit of the above-mentioned world clock will be explained with reference to FIG.
