Abstract

(57) [Summary] [Purpose] In order to carry out international activities, the local time resulting from the time difference between regions must be taken into consideration, and the present invention is a mark for making a conventional analog display clock recognize the region. By adding a disc (4) with the mark, it becomes possible to know the current time of the area from the dial by using the marking as an instruction means. [Structure] A conventional analog clock can be made to recognize a specific area. For example, a disc (4) with the markings (7) and (8) can be added to the clock in the clockwise direction for 12 hours or 24 hours.
Rotate.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a clock for reading the current time in a plurality of areas with a time difference from each other.

[0002]

[Prior art]

 Considering the time difference is essential for international behavior. Usually, tables and dials for time difference conversion are prepared for conversion, or multiple clocks are installed and the time is displayed with each region and representative city name attached. Some analog / digital display clocks can display dual time.

[0003]

[Problems to be solved by the device]

 Since the conventional methods described above have advantages and disadvantages in terms of recognizability, operability, cost, etc., in the present invention, they were made to be a problem to be solved. As a result, it has the following features. (A) No need for troublesome conversion work or operation. (B) Do not accumulate overlapping functions. (C) The time difference can be visually recognized.

[0004]

[Means to solve the problem]

 The mechanism and basic functions of conventional clocks were prepared by adding a disc with a mark to recognize the regions so that the time of multiple regions could be displayed simultaneously, as a solution, and adding this to a mechanical analog display clock. Expand the display function while utilizing.

[0005]

[Action]

 The disc, which is a new instruction means, has a mark that recognizes multiple regions. While rotating once in 12 or 24 hours, the mark instructs the dial to display the time of multiple regions at the same time. To do.

【Example】

 FIG. 1 is an exploded view showing a display unit of a conventional 12-hour display analog timepiece. (1) is a dial. The one with some of the scales and letters / symbols omitted / deleted due to design reasons is generally called a dial. (2) is an hour hand, and (2 ') is an hour hand mounting portion. (3) is a minute hand. In the following description, the same numbers are assigned to the same objects even if the illustrations are different. Next, one embodiment of the present invention will be described. FIG. 2 is an explanatory view of a disk (4) as an instruction means relating to the present invention. , There is a hole (5) at the center of the hole, and the dotted line (6), "LAX and arrow" (7) and "LDN and arrow" (8) are radially marked on the surface. Here, LAX is a notation that recognizes Los Angeles, and LDN is a marker that recognizes London. The relationship between them is (6) as a reference, (7) is at a position of 150 degrees counterclockwise, and (8) is clockwise. They are located at 90 degrees. In this case, the markings (6), (7), and (8) when placed on the dial (1) are arranged in consideration of the time difference between Tokyo, Los Angeles, and London. FIG. 3 is an exploded view for explaining the present invention, in which the disc (4) of FIG. 2 is inserted and combined between the dial (1) and the hour hand (2) of FIG. At the time of combination, the hour hand attaching portion (2 ') penetrates the hole (5), and the hour hand (2) is fixed to the disc (4) with an adhesive (not shown) or the like at the position of the dotted line mark (6). FIG. 4 is an explanatory diagram of the above embodiment when it is actually used. Here, the hour hand and minute hand of the clock are adjusted to Japan Standard Time, and the time of 12:30 Tokyo time is displayed. This watch also displays the commonly used dial (1), the minute hand (3), and the indications (7) and (8) for Los Angeles time of 7:30 and London time of 3:30. doing. In this way, multiple regional times can be displayed according to the number of markings that identify the region. If an adjustment function considering daylight saving time is required, a mechanism may be added for adjustment without fixing the hour hand (2) and the disc (4). In addition, the notation method and ingenuity during actual use and correspondence may be sufficient for changing the date and determining whether it is day or night.

The time of a plurality of regions having a time difference is simultaneously displayed, and a simple, inexpensive, and practical clock is provided.

[0008]

[Effect of the invention]

 INDUSTRIAL APPLICABILITY The present invention can provide a timepiece that can be used in various kinds of timepieces by utilizing the basic structure of an analog timepiece and having a feature in the indicating means, and can be used in an international scene with a time difference.
