Abstract

PURPOSE: To provide a watch with a tide indicator by determining a tide level from the intersection of a water level curve and a mark point of reading and then determining a tide time indicated on a watch for a specific geographic point. CONSTITUTION: The auxiliary dial 7 of a tide indicator 7 disposed on a grid at the gate part thereof is located by means of a pin 7.2 in a small chamber 12.1 of a substrate and the reference point of the dial 7 is aligned perfectly with the vertical axis of 12 o'clock. The tide indicator gate 3.1 on the dial 3 meshes with a mark point 4.10 of reading held by a read grid 4. The tide curve 6.10 of a water level circle 6.3 (every one half day) corresponds to the every hour tide of 62 min 06.5 sec (tide period divided by 12) determined in the radial direction by a mark point of tide time and includes a high tide (PM) mark point 6.51 and a low tide (BM) mark point 6.52. A reference point of the dial 7 is set at the base of the gate while being aligned with the vertical axis (12 o'clock) of the dial and the intersection with the reference mark point represents conditions of the tide determined for the reference point and the date indicated by the watch.

Description

DETAILED DESCRIPTION OF THE INVENTION Several clocks are known that relatively display the tidal changes at a particular location, and are generally composed of a single hand or a disc, which moving at speed,
It gives information about tidal conditions over time without giving a precise indication of water levels. On the other hand, since some products occupy a certain amount of space and consume considerable energy, it is difficult to install them in watches with crystal movements.

On the other hand, known clocks take into account specific values on specific days provided by tidal tables for major and secondary ports, and at the same time take into account specific values for secondary ports and for specific locations. Taking into account the relative values for the situation, tidal changes cannot be directly determined by the nominal value of the water level.

In order to eliminate such inconveniences, it is an object of the present invention to provide a watch equipped with a tidal indicating device, said tidal indicating device comprising, on the one hand, a tidal grid ( on the other hand, one of the grids is constantly moved by a movement with a constant angular velocity depending on the mean period of the tides, and on the other hand an overlapping, concentric, shaped grid containing at least one radial reading. It is equipped with a reading grid, and is characterized by determining the tidal level by the intersection of the water level curve and the reading gauge, and also by determining the tidal time at the time indicated by the clock at a given geographical point.

We reserve the possibility of using each of the features described, alone or in combination, for the purpose of drafting new claims for the purpose of "patent rights" protection.

In FIG. 1, a movement 1 (crystal movement or mechanical movement) is shown, and the central pointer section 2 includes a second hand,
It consists of a minute hand and a clock.

The dial 3 contains a large gate 3.1 of the tidal indicator. Tidal pinion 2.1 of hour wheel 2.11
2, on the other hand, is fixed (by friction) when the peripheral tooth 8.3 is not moved by the reversal axis 1o of the manual correction part of the tidal grid, and the cylindrical mandrel 8.3 concentrically around the pivot axis. 2, concentrically rotating and holding the differential plate 8 which is adjusted by internal teeth 6.4 of the tidal grid 6, and on the other hand, the tidal grid is rotated (counterclockwise) by internal teeth. ) is moved at a constant speed in synchronization with the hour hand of the planetary gear 9 formed by a moving pinion ring,
Exactly one revolution on the reading grid 4 during a time equal to four average periods of the tides and adjusted concentrically by peripheral teeth 4.3 within the cylindrical part 12.3 of the tidal indicator base 12, the reading grid It is fixed (by friction) when it is not moved by the reversing shaft 11 of the manual correction section.

The auxiliary dial 7 of the tide indicator, which is on the grid of the gate part of the tide indicator, is positioned by a pin 7.2 in the chamber 12.1 of the board, so that the reference point of the tide indicator is at 12 o'clock. perfectly aligned with the vertical axis of

In the tidal records (northern Pacific Ocean, Presto Sea area, 1990 and later), if we take the average value of all tides between January 1st and December 31st, the theoretical value of the average tidal period is 12
The time was 25 minutes and 18.47 seconds. If we choose the number of teeth to be 16-10/8 and 53 for the tidal pinion, planetary gear, and tidal indicator internal teeth, respectively, the tidal grid is 12 hours, 25 minutes, and 18.75 seconds (the tidal curve makes one revolution in 4 periods). after one year of operation, it will move between two successive PM (high tides), and after one year of operation it will be 3 times lower than the high tide indicated by the tidal curve.
Minutes 17.4 seconds later The accuracy of the reading is reduced.

The tidal grid and the reading grid are photochemically printed on special paper with a thickness of 0°05 mm, resulting in extremely fine lines, and both grids are directly overlaid to avoid parallax when reading. There is.

In FIG. 2, the pointer 2 and the dial 3 are shown, the tidal indicator gate 3.1 of the dial meshing with the reading mark 4.10 held by the reading grid and the water position 6.1. The (semi-daily) tidal curve 6.10 of 3 corresponds to an hourly tide of 62 minutes 06.5 seconds (tidal period divided by 12) defined radially by the tidal time markers, and the high tide ( PM) gauge 6.51 and low tide (BM) gauge 6.5
2 and the vertical axis of the dial (12 o'clock) at the base of the gate.
There is a reference point for the tide indicator 7 centered on the gate, and on the outer periphery of the gate there is a scale origin 3.11 for "general time".
There is a ``tidal time'' scale on the inner circumference of the gate, and a date gate 3.2. When the time adjustment crown 21.1 is in the intermediate position, turning it by hand in one direction allows you to correct the date, and turning it in the opposite direction allows you to adjust the tidal curve and correct the tidal grille. The intersection points represent the conditions defined in the tide book for the reference point and the date and time indicated by the clock. The manual correction crown 21.2 of the reading grid allows the reading reference points to be adjusted to indicate relative indications in secondary ports in case of discrepancies in tidal changes or requiring particular care and accuracy. In this case, it compensates for the discrepancy between the mean period that conditions the movement of the tidal grid and the actual tidal period at a given date.

FIG. 3 shows a device according to a first embodiment,
In addition, to be able to analyze the tidal changes in a particular area for semidiurnal or mixed tides, a semidiurnal auxiliary tidal curve with the same amplitude as the semidiurnal curve is shown; It is convenient to prioritize the special regional characteristics indicated by the book. For regions whose tidal characteristics are well known, tidal curves specific to such regions can be predicted.

FIG. 4 shows the apparatus shown in the first embodiment and the reading auxiliary gauge 4 which is different from the reading gauge by half the tidal period.
．． 11 is displayed and the reading reference point is relative to the tidal curve near low tide near the center of the dial, use the reading aid reference point corresponding to the tidal curve near high tide near the center of the dial. , the situation at the intersection can be predicted more accurately. On the other hand, special auxiliary reading marks are set at entrances 4 and 21 respectively.
and outlet 4.22 can be arranged independently of each other,
By moving the manual correction part of the reading grid 21.2 at each position, each auxiliary grid is moved so that each such gauging point can be interpreted as
Define a specific period. These markers can be placed corresponding to the readout markers, and when the gate of the tidal curve or the gauge of the BM crosses these points, it is within a period in a special situation with respect to the PM or BM; It can be located at a point determined by the tidal curve defining special circumstances.

A water level curve at least partially on a translucent rim containing a gate allowing time-dependent auxiliary information (e.g. tidal coefficient) to be read on an auxiliary coaxial rim that rotates below the translucent rim at a constant relative speed. It is possible to devise a tidal grid such that the tidal grid is copied.

On the other hand, one of the radial plates on the gate of the tide indicator is marked with scales for the tidal water level (for example, 1/12, 3, 6, 9, and 11 of the tidal difference between Open and PM). You can attach it. Similarly, various nominal values of tides (
It is also possible to use different scales for meters).

When actually using a clock, there is generally a problem of defining the water level according to the time (on the zero point on the chart) with respect to the PM and leaf values for the date and location.

For this reason, FIG. 5 shows the tide indicator device 1 of the first embodiment.
and a manually adjustable rotating rimmed case 21, which has an inner rim 31 of the case and a water level constant scale 31.1 similar to this rim, which can only be turned clockwise on the inside. of the tidal range (water level difference between PM and BH), corresponding to each water level range of the tidal grid and corresponding to the initial position of the effective leaf for the two central scales. In order to adjust the angular position of the "water level difference" logarithmic scale with respect to the same scale 32.1 graduated in twelfths, the water level addition or Subtraction can be performed.

Knowing the PM and BH values shown in the tide book, one can adjust the relative position of the watch glass rim accordingly, and the change in sea level (in nominal values) during the current cycle. can be known instantly.

The tidal grid may also include time markers with respect to the PM (eg, in closed water ranges) useful for indicating current flow. (Current charts are established for each hour before or after high tide.)
