Description

Clock and clock face

The present invention relates to a clock and a clock face.

Various configurations have been proposed for clock faces and clocks. In such timepiece dials and timepieces, there is also known a timepiece structure in which the time at a plurality of points can be read by a single unit. As such a timepiece, for example, a watch disclosed in Patent Document 1 is known.
Patent Document 1 discloses a configuration of a world clock including an hour hand and a minute hand having a plurality of hands protruding at a predetermined angle according to a time difference in order to display time in a plurality of cities at the same time.

Published Patent Gazette Japanese Laid-Open Patent Publication No. 5-172954

In the world clock disclosed in Patent Document 1, it is necessary to select a specific country or city in advance and create an hour hand in which the pointer protrudes at an angle corresponding to the time difference. Time cannot be displayed flexibly.
In addition, when the number of hands increases, the minute hand is in a state of being mixed in the hands, which makes it difficult to find the minute hand and makes it difficult to read the time in a short time.

Therefore, an object of the present invention is to provide a clock and a dial for a clock that can display a plurality of hour hands with an arbitrary time difference and can display a detailed time by a minute hand.

In order to solve the above problems, the present inventor has intensively studied, and as a result, has come up with the following configuration.
Specifically, the timepiece described in claim 1 has a main scale that divides one circumference into 12 divisions and 24 divisions on the outer edge of the board surface, and an auxiliary scale that divides one hour divided by the main scale into 15 minute intervals. A first dial provided with a plurality of hour hands each having a rotation axis at the center of the first dial, each indicating a time, and one round corresponding to one hour, A second dial provided with a scale that divides one revolution into 5 minute intervals, a rotation axis at the center of the second dial, and a time point indicated by any of the plurality of hour hands And a minute hand for indicating a minute unit.

The timepiece according to claim 2 is the timepiece according to claim 1, characterized in that the second dial face is arranged eccentrically in the first dial face.

The timepiece according to claim 3 is the timepiece according to

claim

1 or 2, characterized in that the plurality of hour hands can individually change the indicated positions in the first dial.

A timepiece according to claim 4 is the timepiece according to any one of claims 1 to 3, wherein the plurality of hour hands are formed so as to be distinguishable from each other.

The timepiece dial according to claim 5 has a main scale that divides the circumference into 12 divisions or 24 divisions on the outer edge of the board surface, and an auxiliary scale that divides one hour divided by the main scale into 15-minute intervals. It is characterized by having both the provided 1st dial and the 2nd dial provided with the scale which makes the circumference correspond to 1 hour, and divides the circumference into 5 minutes intervals.

The timepiece dial according to claim 6 is the timepiece dial according to claim 5, wherein the second dial is arranged eccentrically in the first dial. .

By adopting the configuration according to the present invention, the approximate time can be read in a short time even with only the hour hand, and the detailed time can also be read with the minute hand. Further, even when a plurality of hour hands are provided, it is possible to provide a timepiece and a timepiece dial that can read the time indicated by each hour hand in a short time.

Specifically, according to the timepiece described in claim 1, the first dial and the first dial which are provided with the main scale and the auxiliary scale on the outer edge portion of the board surface and can display the rough time by the hour hand, The dial has a rotation axis at the center of the dial, and a plurality of hour hands that can each indicate the time at the first point and another point having a predetermined time difference from the first point, and the time by the minute hand A second dial that can be displayed in minutes, and a minute hand that has a rotation axis at the center of the second dial and indicates the minute unit of time indicated by any hour hand Thus, it is possible to read the approximate time at a plurality of points in a short time just by looking at the first dial and the hour hand, and the time can be read accurately in minutes by moving the line of sight to the second dial.

In this case, according to the timepiece described in claim 2, since the second dial is arranged eccentrically in the first dial, a compact timepiece can be obtained, and the second dial Since the minute hand arranged on the dial does not hinder reading of the hour hands arranged on the first dial, the time can be read more easily.

According to the timepiece described in claim 3, the plurality of hour hands are arranged in the first dial according to the time at the first point and another point having a predetermined time difference from the first point. Since the designated position can be individually changed, time display at any of a plurality of points can be appropriately selected, and convenience is greatly improved.

Furthermore, according to the timepiece described in claim 4, since each hour hand is formed so as to be distinguishable from each other (so as to be distinguishable from other hour hands), it is possible to prevent erroneous reading of time.

According to the timepiece dial of claim 5, the main dial and the auxiliary scale are provided on the outer edge of the board surface, and the first dial capable of displaying a rough time by the hour hand, and 1 hour In addition to a second dial that is provided with a scale that divides the time into 5 minute intervals and can display the time in minutes by the minute hand, a plurality of hour hands that can each indicate the time are provided as the first character. By arranging it on the board, just looking at the first dial, you can read the approximate time at the first point and other points with a time difference from the first point. By disposing, the time can be accurately read in minutes if the line of sight is moved to the second dial.

Furthermore, according to the timepiece dial of the sixth aspect, the second dial is arranged eccentrically in the first dial, so that a compact dial can be obtained. Since the minute hand arranged on the dial does not hinder the reading of each hour hand arranged on the first dial, the time can be read more easily.

It is a front view of timepiece 10 (10A) concerning this embodiment. FIG. 2 is a front view of the timepiece 10 (10A) in a state in which a time 3 minutes after the time shown in FIG. 1 is indicated.

Hereinafter, embodiments of a timepiece and a timepiece dial according to the present invention will be specifically described with reference to the drawings. In the present embodiment, for convenience of explanation, the clock face is simply referred to as the dial 40 for explanation.
As shown in FIG. 1, the timepiece 10 according to the present embodiment is a table clock type timepiece that is an example of a “timepiece”, and is provided inside the first dial 20 and the first dial 20. The dial 40 having the second dial 30 for displaying the minute unit of the time and any two times (for example, the Japanese time (the time at the first point), the Japanese time and the predetermined time The first and

second hour hands

52 and 54 for displaying the time at the point having the time difference (time at other points), and the time at least one indicated by the first and second hour hands (as an example, the first It has a minute hand 60 and a leg 11 for displaying the time indicated by the hour hand 52 in units of minutes.

The first dial 20 has a main scale 22 indicating time in integer units (an example of a “main scale that divides a circuit into 12 divisions”), and an arrangement interval of the main scale 22 is equally divided into four (depending on the main scale). An auxiliary scale 24 (which divides the divided hour every 15) is disposed at the outer edge of the board surface. Although different from the timepiece 10 of this example, it is possible to adopt a configuration in which a “main scale” that divides one round into 24 divisions is provided on the outer edge of the board surface of the “first dial” (not shown). . In this case, the unit of time at each time is displayed as an integer at a position near the main scale 22 (outer edge portion of the first dial 20). Further, the auxiliary scale 24 is marked with a character “30” at a position indicating 30 minutes at each time.

Also, the first dial 20 is provided with first and

second hour hands

52 and 54 for indicating the time, respectively. In this case, one end of each of the first and

second hour hands

52 and 54 is pivotally attached to the rotary shaft 56 at the center position of the first dial 20. Both the first and

second hour hands

52 and 54 operate in the same manner as a short hand (hour hand) of a normal timepiece. In other words, in the timepiece 10 in which the circumference of the first dial 20 is divided into 12 divisions by the 12 main scales 22, for example, at “10:00”, the first hour hand 52 or the second hour hand 52 The hour hand 54 indicates the portion of the main scale 22 corresponding to “1 o'clock” of the 12 main scales 22, and the 1st hour hand 52 or the second hour hand 54 every time one minute passes thereafter. Is inclined by 0.5 degrees clockwise and is “1:30”, the first hour hand 52 or the second hour hand 54 corresponds to “1 o'clock” of the 12 main scales 22. An intermediate portion between the scale 22 and the main scale corresponding to “2 o'clock” is indicated. In this case, the movement of the first and

second hour hands

52 and 54 is not described in detail, but a known configuration such as a mechanical type or a quartz type can be used.

In the timepiece 10 of this example, as an example, of the two

hour hands

52 and 54, the first hour hand 52 indicates the Japanese time on the first dial 20, and the second hour hand 54 is The first dial 20 can indicate the time at a desired point having a predetermined time difference from the Japanese time. As shown in FIGS. 1 and 2, the first hour hand 52 and the second hour hand 54 can be distinguished from each other only with a glance. It is preferable that at least one of at least one of the color and shape of the second hour hand 54 is different. Specifically, in the timepiece 10 of this example, as an example, in order to make the first hour hand 52 and the second hour hand 54 distinguishable from each other, both hour hands are formed so that the shapes are equal to each other and the colors are different from each other. However, instead of such a configuration, the

hour hands

52 and 54 are configured such that the colors are the same and the shapes are different from each other, or the colors are different from each other and the shapes are also different. Both

hour hands

52 and 54 may be configured to be different from each other.

The second dial 30 is formed to have a diameter less than half that of the first dial 20 and is provided in the lower region of the first dial 20 (eccentrically). As described above, the second dial 30 is for displaying the minute unit of the time, and in the present embodiment, one round of the second dial 30 corresponds to one hour (60 minutes). At the same time, a scale 32 is provided every 5 minutes (an example of a 5-minute scale: “a scale that divides a circle corresponding to one hour into 5-minute intervals”), and a number representing “minute” corresponding to each scale 32 is provided. And the scale 33 (1 minute scale) which divides | segments between the

scales

32 and 32 adjacent in the circumferential direction at intervals of 1 minute is provided. There is one minute hand 60 disposed on the second dial 30. In addition, the minute hand 60 is attached to one end portion thereof by a rotation shaft 66 at the center position of the second dial 30. The minute hand 60 operates in the same manner as a long hand (minute hand) of a normal timepiece. In other words, for example, when the minute hand 60 is “10:00”, the portion of the scale 32 corresponding to “0 minute (60 minutes)” of the 12 scales 32 is indicated, and 1 minute has passed thereafter. Each time it is tilted, it tilts 6 degrees clockwise, and when it is “1:05”, it indicates the part of the scale 32 corresponding to “5 minutes”. In this case, the movement of the minute hand 60 can employ a known movement configuration as in the case of the first and

second hour hands

52 and 54.

As described above, the timepiece 10 includes the first dial 20 with the auxiliary scale 24 that divides the hour every 15 minutes and the dial 40 provided with the second dial 30 indicating the minute unit of the time. By adopting the configuration, it is possible to read the approximate time to the minute unit only by looking at the first dial 20. In the present embodiment, since the first and

second hour hands

52 and 54 are provided, the time at two points can be read by one timepiece 10. Specifically, in the example shown in FIG. 1, it can be read that the first hour hand 52 indicates “around 1:45” and the second hour hand 54 indicates “around 10:00”. . In the example shown in FIG. 2, the first hour hand 52 indicates the time when several minutes have elapsed from “1:45”, and the second hour hand 54 indicates the time when several minutes have elapsed since “10:00”. Can be read when instructed. In this case, in the timepiece 10 of this example, unlike a general timepiece, the minute hand is not provided concentrically with the first and

second hour hands

52 and 54. For this reason, the timepiece 10 of this example has a plurality of hour hands (in this example, the first and second hour hands 52 and 54) provided concentrically, but the minute hand prevents reading of each hour hand. Therefore, it is possible to accurately and easily read the time indicated by each hour hand.

In addition, since the second dial 30 indicating the minute unit of the time is also provided inside the first dial 20, the time can be accurately read in minutes by slightly moving the line of sight within the clock 10. Is also easy. Specifically, according to the timepiece 10 of this example in which the minute hand 60 is synchronized with the operation of the first hour hand 52, in the example shown in FIG. 1, the minute hand 60 indicates “45 minutes”. In the example shown in FIG. 2, it can be read accurately if the minute hand 60 indicates “48 minutes”.

In the timepiece 10 according to the present embodiment, the positional relationship between the first hour hand 52 and the second hour hand 54 can be changed to an arbitrary positional relationship by a time adjusting means (not shown) such as a crown. . For example, when the crown is pulled once from the initial position (the crown is pulled out by one step), the second hour hand 54 can be adjusted. Further, when the crown is pulled once more (pulled twice from the initial position: the second hour hand 54 is pulled out one step from the adjustable state), the first hour hand 52 becomes adjustable. In the timepiece 10 according to the present embodiment, as an example, a configuration in which the minute hand 60 is adjusted in synchronization with the adjustment operation of the first hour hand 52 is employed. Specifically, both the first hour hand 52 and the minute hand 60 can be adjusted by pulling out the crown from the initial position in two stages so that the first hour hand 52 can be adjusted. For this reason, in the timepiece 10 of this example, it is not necessary to provide a function for adjusting only the minute hand 60.
With the configuration of the time adjusting means, it is possible to easily operate only the second hour hand 54 that frequently changes the set time, and there is no possibility of operating the first hour hand 52 and the minute hand 60 by mistake. It is also convenient.

As described above, the positional relationship between the first hour hand 52 and the second hour hand 54 can be adjusted by an extremely simple operation. Therefore, when traveling abroad, the crown can be pulled only once (can be pulled out by one step). For example, the second hour hand 54 can be adjusted, and the adjustment for indicating the local time can be easily performed at a travel destination or the like. At this time, since the first dial 20 is provided with the auxiliary scale 24 at intervals of 15 minutes, the time setting of the second hour hand 54 can be performed very easily. When the time of the second hour hand 54 is set (when the crown is pulled out by one step), the first hour hand 52 and the minute hand 60 that indicate the Japanese time are operated. Therefore, the Japanese time indicated by the first hour hand 52 and the minute hand 60 can be kept accurate.

As described above, the timepiece 10 according to the present invention has the dial 40 constituted by the first dial 20 and the second dial 30, thereby allowing the first and second hour hands 52, The approximate time can be read simply by reading 54. In addition, since the first and

second hour hands

52 and 54 are provided, the time at two points can be displayed simultaneously on one clock 10, which is very convenient. Further, the time can be accurately read in units of minutes simply by moving the line of sight to the second dial 30.

In the present embodiment, the second dial 30 is arranged in the lower half region of the first dial 20 in a state of being eccentric with respect to the first dial 20, but the second dial 30 may be provided at another position in the first dial 20.
Further, the second dial 30 is not necessarily provided inside the first dial 20, and is adjacent to the first dial 20, and the first dial 20 and the second dial 30 are arranged in parallel. It is also possible to adopt a configuration arranged in

In the present embodiment, the first dial 20 is provided with the first and

second hour hands

52, 54. However, three or

more hour hands

52, 54,... Of course, it is also possible to adopt a disposition form.
Furthermore, although the minute hand 60 has been described as being synchronized with the operation of the first hour hand 52, the minute hand 60 may be synchronized with the operation of the second hour hand 54, or only the minute hand 60 may be adjusted by the time adjusting means. It is possible to adopt a form of adjustment (a form of adjusting the minute hand 60 separately from the first hour hand 52 and the second hour hand 54).
1 and 2 show a so-called table clock-type timepiece 10, but it is of course possible to adopt a watch-type configuration like a timepiece 10A in which a belt 12 is attached instead of a leg 11 in the timepiece 10. Of course, it is possible to eliminate the legs 11 in the timepiece 10 and the belt 12 in the timepiece 10A to form a wall-mounted timepiece (not shown).

By adopting the configuration according to the present invention, the approximate time can be read in a short time even with only the hour hand, and the detailed time can also be read with the minute hand. Further, even when a plurality of hour hands are provided, it is possible to provide a timepiece and a timepiece dial that can read the time indicated by each hour hand in a short time. Specifically, according to the timepiece of the present invention, the first dial and the first dial that are provided with the main scale and the auxiliary scale on the outer edge of the board surface and can display the rough time by the hour hand, The center of the dial has a rotation axis, and the time is divided by a plurality of hour hands capable of indicating the time at the first point and other points having a predetermined time difference from the first point, and the minute hand. By having a second dial that can be displayed in units, and a minute hand that has a rotation axis at the center of the second dial and indicates the minute unit of time indicated by any hour hand By simply looking at the first dial and the hour hand, the approximate time at a plurality of points can be read in a short time, and the time can be accurately read in minutes by moving the line of sight to the second dial.
