Description

Field of technology

The utility model relates to the watch industry and can be used in watches to simultaneously display smooth and discrete indications on the dial. For example, the mechanism can be used with a calendar mechanism. The mechanism can also be used to indicate the phases of the moon in time instruments for an accurate and realistic display of the phases of the moon in mechanical watches.

State of the art

Smooth and discrete clock indication refers to the different ways in which time is displayed on a dial or display. Let's look at each of them.

Smooth time indication involves smooth movement of the hands or changing numbers on the display to show the time. Instead of instantly jumping from one number or position to another, the smooth indication offers a gradual change in values. For example, when changing from one hour to another, the hands can move smoothly across the dial, providing a continuous perception of time.

A discrete time display, unlike a continuous time display, displays time instantly without smooth transitions or changes. The watch face or display may use discrete digits or segments to display hours, minutes, and seconds. This approach offers a sharper, clearer display of time where values change in leaps and bounds.

Specific implementations of continuous and discrete time display may vary between watches and devices.

Some watches may offer a combination of continuous and discrete displays. For example, smooth transitions between numbers on a display can be used, while the appearance of the numbers itself is instantaneous and discrete. Also, the smooth and discrete indication mechanism is used in watches that have additional functions, such as dates, additional digital indicators or chronographs (stopwatches). These functions may be represented by additional numbers, windows, or buttons on the dial or body.

It is known that in mechanical watches, discrete time indication can be represented using a digital or analogue dial. In particular, some mechanical watches may have an additional digital window that displays digits for the hours, minutes or seconds. This window can be located on the dial or on another part of the watch movement. Numbers can be represented using numeric segments or by displaying printed digits.

Additionally, instead of traditional markers and hands, a mechanical watch may have a circular dial with a series of individual numbers representing the hours, minutes and seconds. As the hands move, they point to the corresponding numbers on the dial, providing a discrete time indication.

Mechanical watches may also use markers or indices on the dial to indicate the hour, minute, and second markers. These may be small lines, dots or other symbols that are placed around the watch face to indicate the time. When the hands move, they point to the corresponding marks or indices on the dial.

Some mechanical watches may use sliders or windows to indicate the time. For example, a number window can move around the watch face, showing the current number for hours, minutes or seconds. Sliders can be made as separate elements or integrated into the watch face.

Some mechanical watches have several separate displays to indicate the hours, minutes and seconds. Each display has its own set of numbers or symbols that allow each unit of time to be tracked separately.

Mechanical watches may also have analog windows to display the date, day of the week, or other additional functions. For example, a number window may appear in a separate section on the watch face, showing the current date or day of the week.

Mechanical watches may use indicators to indicate special functions or modes. For example, the indicator may light up when the alarm or chronograph function is activated.

When talking about mechanical watches, the term "aperture" is usually used to describe a special window or opening on the dial through which additional information can be seen.

One of the most common uses of an aperture is to display the date. The clock may have a window in which the current date is displayed as a number. The numbers can be printed on a disk or mark that rotates for each day to show a new number.

Some mechanical watches offer moon phase display. In this case, the aperture can be made in the form of a disk-shaped window, which depicts the Moon in various phases. Rotating the disc allows you to track the current phase of the moon.

On some watches, the aperture may be positioned horizontally on the dial. This can be used to display additional information elements such as a second time zone or a day/night indicator.

On some mechanical watches, the aperture may be used to indicate the seconds. It can contain numbers from 0 to 60 or marks indicating each second, and moves according to the elapsed time.

The aperture provides a unique way to display additional information on the dial of a mechanical watch.

The aperture can also be used to indicate different modes or functions available on the watch. For example, a watch may have an aperture through which the currently selected mode, such as a timer, alarm, or chronograph mode, is displayed.

In addition, in self-winding mechanical watches, the aperture can be used to display the energy level in the battery or in the mechanical power reserve. It may provide a scale that indicates the energy level and helps the wearer know when the battery needs to be recharged or replaced.

In some mechanical watches, the aperture can be used to create animations or effects. For example, the aperture can open and close, move, or change color, adding additional visual elements and interesting details to the watch face.

In this way, the aperture can be used to indicate various complications or additional functions provided by a mechanical watch. For example, a watch may have an aperture through which the phase of the moon, the day of the week, the month, or even the equation of time are displayed. This allows the wearer to quickly and easily view additional information. Also in mechanical watches with multiple time zones, the aperture can be used to indicate the selected time zone. Time zones can be represented as a city, an abbreviation, or a numeric value, allowing the wearer to easily track time in different time zones.

In addition, the aperture can be used to display intermediate results or timer or chronograph measurements. For example, the aperture can show the number of minutes or seconds that have passed when a timer or chronograph is running.

Here are some examples of mechanical watches using aperture:

Patek Philippe Calatrava Ref. 5227: This classic Patek Philippe watch design features an aperture to display the date between 4 and 5 o'clock on the dial. The aperture is presented in the form of a window with a digital date display.

Jaeger-LeCoultre Master Control Date: This Jaeger-LeCoultre model features a date aperture at 3 o'clock. The date numbers appear in a window-shaped aperture on the dial.

Rolex Sky-Dweller: This Rolex has apertures to display a second time zone and date. A second time zone is displayed as three apertures near the dial, and the date is displayed in an aperture at 3 o'clock.

Audemars Piguet Royal Oak Perpetual Calendar: This Audemars Piguet model uses apertures to display the day of the week and month. The apertures are located at 12 and 9 o'clock respectively.

Blancpain Fifty Fathoms Bathyscaphe: This Blancpain model has an aperture to display the moon phase at 6 o'clock. The aperture is presented in the form of a window with an image of the Moon and its phases.

Thus, taking into account that smooth and discrete indications in watches are used quite often and this mainly concerns complicated watch movements, one of the main engineering tasks is to develop a single mechanism that allows for simultaneous discrete and smooth indications on watches. Moreover, such a mechanism should be simple and contain a small number of components to increase its reliability. Also, the mechanism must provide high accuracy in order to be used in watches.

In the prior art, no sources of information have been identified that reveal the device for simultaneous discrete and smooth indication on the dial.

Task and technical result

The objective of the proposed utility model is to develop and practically implement a simple mechanism that takes up little space in the watch case and at the same time allows the principle of smooth and discrete movement of the indicator to be used at the same time.

The technical result consists in creating a simplified design of a double indication mechanism with a smooth and discrete position of indicators on the dial, ensuring high accuracy of indication, which is reliable and takes up little space in the watch case.

In this case, the dual indication mechanism can be designed to allow smooth and discrete indication of moon phases.

In addition, the dual indication mechanism can be configured to provide smooth and discrete indication of Earth phases.

Also, the dual indication mechanism can be made with the possibility of a smooth and discrete indication of the days of the week, where the flow of the days of the week is smoothly displayed and the current weekday or weekend day is discretely shown in the aperture in signs, letters or color.

Also, the dual indication mechanism can be made with the possibility of smooth and discrete indication of the zodiac signs, while the smooth movement is marked on the annual disk, and the discrete designation of the zodiac signs is displayed in the dial aperture.

Implementation of a utility model

According to the utility model, the device for a double indication with a smooth and discrete position of the indicator on the watch dial has a simple design. To understand the essence of the proposed solution, the calculation of the wheelbase of the gearbox is presented using the example of the implementation of an indication of the smooth and discrete position of the moon phases. Considering that the schematic diagram of the mechanism design is shown in Fig. 2, it is obvious that the presented detailed calculation of the wheelbase of the kinematic system interacting with the clock mechanism is variable and in a similar way, an embodiment of the mechanism for indicating the days of the week can be calculated, where the flow of the days of the week will be smoothly shown during the week and shown discretely in the aperture by signs , letters or color weekday or weekend now. Also, for example, to display zodiac signs. For example, smooth movement is marked on the annual disk, and discrete movement is indicated by the signs of the Zodiac in the aperture.

It is known that the basic principle of a wheel drive is that two or more wheels or gears are connected to each other using gear connections. When one wheel is driven, it transfers rotational motion to another wheel or gear, which in turn transfers energy to the next wheel or gear, and so on. In this way, energy is transferred through the transmission chain.

Watches use a wheel drive to transfer energy from a spring mechanism or battery to various functional elements such as hands and calendars. Wheel drive in watches is usually based on the use of gears that interact with each other.

Thus, the transmission mechanism includes various gears and gears that connect and interact with each other. These components form a transmission ratio so that energy can be transferred from the source to the various functional elements of the watch. Thus, gears transmit energy to the arrow axes to ensure their rotation. Each hand (hour, minute, second) usually has its own axis and its own gear to transmit energy. The watch also uses additional gears to operate the calendar, moon phase and other functions.

In mechanical watches, a gearbox usually ensures smooth and continuous movement of the hands. The gearbox consists of gears of various sizes that interact with each other to transfer energy from a source (pendulum or spring) to the points. However, some mechanical watches may use discrete gear movement mechanisms for additional functions. For example, in chronographs (watches with a stopwatch function), the gearbox may have a mechanism that allows the stopwatch to be turned on and off with fractional second precision. This is achieved through discrete movements, which are carried out by pressing the start/stop button or reset the stopwatch. Also, in some complex mechanical watches, such as complication watches, the gearbox may have discrete movements to display various functions, such as moon phase, calendar, or alarm indications. In these cases, additional gears and mechanisms are used to make discrete movements that change the positions of additional indicators or pointers.

Considering that a simple gear mechanism for simultaneous smooth and discrete display of increased accuracy is currently unknown, we have developed a mechanism design that takes up little space in the watch case and at the same time allows the principle of smooth and discrete movement of the indicator to be used simultaneously. In our application, we examined in detail the mechanism for indicating the phases of the moon. However, it obviously follows that this option is presented for understanding the essence of the claimed device by a person skilled in the art and in no way indicates the only possible application of the proposed dual indication mechanism with a smooth and discrete position of the indicators on the dial.

Below we consider in detail an example of the implementation of the claimed mechanism. Since one of the most common complications in watches is the indication of moon phases, the considered example reveals in detail the indication of moon phases for a clear and accurate understanding of the essence of the claimed device.

The operating principle of the display device with a smooth and discrete position of the moon phases is clearly demonstrated in Fig. 1-3 and is as follows.

As shown in FIG. 3, the dual indication gearbox interacts with two moon phase indications, the apertures of which are located above the discs of smooth and discrete moon phase indication. In fig. Figure 1 shows what a watch dial might look like if it contains two moon phase apertures. Moreover, in FIG. 1 shows aperture 7 for smooth indication of moon phases and aperture 8 for discrete indication of moon phases.

The double indication mechanism itself with a smooth and discrete position of the indicators on the dial, using the example of an indication device with a smooth and discrete position of the moon phases, is shown in detail in Fig. 2. As can be seen in FIG. 2, the claimed dual indication mechanism with a smooth and discrete position of the indicators on the dial, using the example of an indication device with a smooth and discrete position of the moon phases, has a single dual indication gear kinematically connected to the clock mechanism. In particular, according to the proposed solution, from a standard watch mechanism containing a minute wheel 9, a bill wheel 10, a bill wheel 11 and an hour wheel 12, making a revolution in 12 hours, through an additional hour wheel 13, the movement is transmitted to the daily wheel 14, making one revolution per day.

Next, the movement is transmitted to the dual indication gearbox for smooth indication of the lunar phases as follows. On the daily wheel there is the first trib of the gearbox 15, which transmits rotation to the first wheel of the gearbox 16, on the axis of which the second trib of the gearbox 17 is located. The second trib of the gearbox 17 transmits rotation to the second wheel of the gearbox 18, on the axis of which the third trib of the gearbox 19 is located. The third trib The gearbox 19 transmits rotation to the third wheel of the gearbox 20. On the axis of the third wheel of the gearbox 20 there is a fourth wheel of the gearbox 21, which transmits rotation to the fifth wheel of the gearbox 22, which makes one revolution in 59.0625 days, that is, in two lunar phases.

In this design, the dual indication gearbox for smooth indication of lunar phases has the following numbers of teeth: the first gearbox trib - 16 teeth, the first gearbox wheel - 70 teeth, the second gearbox trib - 10 teeth, the second gearbox wheel - 25 teeth, the third gearbox wheel - 10 teeth , the third gear wheel is 25 teeth, the fourth gear wheel is 25 teeth, the fifth gear wheel is 54 teeth. 70/16⋅25/10⋅25/10⋅54/25=59.0625, which is quite close to two lunar phases (2⋅29.53059=59.06118).

On the fifth wheel of the double indication gearbox there is a cam for a smooth indication of the moon phases 23 and a disk for a smooth indication of the moon phases 24. Due to the smooth constant movement of the disk for a smooth indication of the moon phases 24, the smooth movement of the moon indicator is displayed on the clock dial in aperture 7.

At the same time, the cam of the smooth moon phase indication 23 engages with the discrete moon phase indication switch 25 through two pawls 26a and 26b of the discrete moon phase indication switch 25, which are fixed by the spring 27. Thus, the ratchet wheel of the discrete moon phase indicator 29 is switched, on the axis of which there is a disk for discrete indication of moon phases 30.

The discrete moon phase indication switch 25 is fixed by the spring of the discrete moon phase indication switch 28. The ratchet wheel of the discrete moon phase indicator 29 engages with the latch of the discrete moon phase indicator 31, which fixes it in one of the positions. The latch of the discrete moon phase indicator 31 is held in its operating position by the sprocket spring 32.

This design allows for double indication as follows: the cam for the smooth moon phase indication 23 makes one full revolution in two lunar phases, which are smoothly displayed on the disk for the smooth moon phase indication 24. In this case, the specified cam for the smooth moon phase indication 23 is designed in such a way that It has special recesses. In addition, the use of two pawls of the discrete moon phase indication switch 26a and 26b on one discrete indication switch 25 is geometrically designed in such a way that, together with the recesses on the cam of the smooth moon phase indication 23, they create the most accurate switching of the discrete indication, accurately showing the onset of the main phases of the Moon. Moreover, this design allows for accurate discrete indication of moon phases with a minimum number of elements used. This design does not require a central location of the axis of the indication disks, it allows for double indication compactly with a minimum number of parts and space, due to the location of the pawl spring of the discrete moon phase indication switch 27 directly on the discrete moon phase indication switch 25. At the same time, there are recesses in the cam of the smooth phase indication The moons 23 have a surface thickness in contact with the discrete moon phase indication switch 25, equal, in the presented example for the moon phase indication, to 1/59 of the circumference.

The claimed dual indication mechanism with a smooth and discrete position of the indicators on the dial can be used both with a standard watch mechanism and with a watch mechanism with additional functions, for example, such as a clock mechanism for a 24-hour dial or a clock mechanism with the ability to display world time and etc.

It is quite obvious that the proposed dual indication mechanism with a smooth and discrete position of the indicator on the dial can be installed in both stationary watches and portable watches.

As a result of the above, we can conclude that the implementation of the utility model ensures the achievement of the required technical result, which consists in creating a simplified design of a double indication device with a smooth and discrete position of the indicators on the dial, ensuring high accuracy of indication, which is reliable and takes up little space in the watch case .

The analysis also shows that all the general and specific features of a utility model are essential, since each of them is necessary, and together they are not only sufficient to achieve the purpose of the utility model, but also allow the utility model to be implemented industrially.
