Clock with day and date display

The invention relates to a watch, in particular a watch such as Wrist watch with a drive for gradually rotating a date ring having at least one number circle and a concentric day ring with a day circle, both of which are covered by a dial, which has at least one main day window and one main date window, which are combined into a common main window and which make a weekday of the day circle or the associated date of the number circle visible.

There are already clocks known that have a date ring with a Have a circle of digits. This date ring is mechanical or electric drive gradually moved so that every twenty-four hours the date ring moves by one The next step is the one that is adjacent to the circumferential distance Corresponds to digits of the number circle. The date ring is covered by the dial, and this has a fen, ster, through which one digit of the circle of digits is then visible, so that the viewer of the clock can then determine can indicate the date of the day in question.

It is also known to attach a day ring in addition to such a date ring, on which in a day circle the days of the week are arranged. The day of the week in question can then be read through a second window belonging to the displayed date.

This allows the clock to display some important information can be read about the day in question, but this is far less than the information on a calendar, for example. The invention is therefore based on the object to improve the clock so that more information about the relevant || i period exist. This object is achieved in the aforementioned clock according to the invention in that to both sides of the main window at least one lift window each to make the previous and following days visible is present and preferably the associated day and date windows are linked by visual features. This means that the entire day information can also be read off for other days, and it is particularly advantageous if a total of one week is recognizable for the viewer. This can be done on both sides of the main window there are three further secondary windows that relate to the three preceding and the three following days, of which both the day of the week and the actual date can now be seen.

It is also known to attach small plates to the bracelet of wristwatches, on which the day data for a whole month are given, so that it can be read off which dates for a Monday or Wednesday, for example belong. However, it is necessary to change this plate every month, and these plates are often lost, so that this is not a satisfactory solution.

According to a development of the invention, which also for itself is only significant, a remedy is provided here that the date ring has at least three identical circles of digits Number of digits, the digits of which lie radially one behind the other in a row of digits and each differed by a week are, and that the date windows each have a row of digits to make visible. This then appears in the correspondingly enlarged Window not only one digit, but several, for example three or four digits, so that now clearly the same days of the week in the same or the following month for all months with 31 days are recognizable. In months with only 30 days, the information in a series of digits is only partially correct, namely as far as it is lie in the same month. However, as far as these details refer to the next month, there is a difference.

To now the information also for months of 30 days or less correct, the date ring can advantageously be divided into partial rings, each with a circle of digits wear. These partial rings are then locked to one another so that they each as a whole from the step-by-step movement Drive can be switched on, but then these parts can- rings from the outside, for example with a small tool or the like, relative to one another around the corresponding Steps are adjusted.

and a cover plate 12 a clockwork is arranged, which has a conventional frame. From this are a lower board 14, a top plate 16 and a spacer column 18 are shown. In the boards is in an unspecified manner a balance wheel 2o, which is connected to a spiral spring 22, is mounted. In the case of an electric watch, the balance is maintained 2o drive pulses in known and therefore not shown Way. The drive takes place via a lifting pin 24 and a pivotable armature 26, which is connected to a ratchet wheel 28 by means of armature pins advances step by step. The ratchet wheel acts on the hands via a chain of wheels. Of these parts there are only one Second wheel 3o, a minute wheel 32 and an hour tube 34 with hour hand 36 supported in the upper plate 16. Since this whole pointer drive system is known as such and does not form part of the invention, it is here not explained in detail. For the sake of completeness, it should be mentioned that the drive also takes place purely mechanically in a known manner can.

A date pinion 38 is preferably in one piece on the hour tube 34 provided, which cooperates with the internal toothing of a cam ring 4o, which rotates on a guide disk 12 is arranged, which in turn is firmly attached to the upper plate 16. The date pinion 38 slides on this guide disc 42 and works with its four teeth 44 with eight Internal teeth 46 of the cam ring 4o together. The cam ring 4o has the actual cam surface 48 on its circumference a run-off surface 5o and a run-off edge 52.

The cam ring 4o comprises a date pawl 54 which can be pivoted on the upper plate about a pin 56 which is shown in FIG a slot 5 8 of the date pawl 54 engages. One Pressure spring 6o tries to move the date pawl 54 into the position shown in FIG. 3, in which a switch nose 6 2 rests against an internal tooth of an internal toothing 6 4 of a date ring 6 6, which is rotatable on the upper plate 16 is rotatable along an annular shoulder 68 of this plate. ^ Furthermore, a date pawl 7o is provided, which is around a Pin 72 is pivotable and with a locking tooth 74 in a Tooth gap of the internal toothing 64 of the date ring 66 engages under the action of a spring 76. The date pawl carries 7o furthermore a day detent spring 78. Further features of the date pawl and date detent pawl will be discussed further below.

Furthermore, a day ring 8o is rotatably arranged on the date ring 66, which is guided on guide pins 82 and an internal toothing 84 has. With this the already mentioned day locking spring 78 cooperates, which in the rest position, according to FIG. 3 in a tooth gap of the internal toothing 84 engages. The date pawl has at the end of a Klinkenanas 86 two lugs, namely a retaining lug 8 8 and a switching lug 9o and further a lifting tooth 92, which is in a detent of the date pawl 7o intervenes.

In Fig. 4, the date ring 6 6 is shown in plan view. It has a total of three circles, namely from the inside out a first circle of digits loo, a second circle of digits Io2

Fig. 5 shows the day ring 8o with a day circle Io6 of a total of fourteen weekday abbreviations corresponding to two weeks.

The day ring 8o and the date ring 66 are on a dial 91 overextended, according to a week and the markings of the day ring has seven day windows 96/1 to 96/7 and also seven date windows 98/1 to 98/7. The middle one Day window 96/4 and the middle day window 98/4, which are referred to as the main day window and main date window are indicated by a middle stripe and show the day of the week in question and the date of the associated Day and also the dates of the same days of the week in the two following weeks, this date being in next 31 day month can be. On either side of the main window there are three "additional windows", each facing the refer to the three preceding and the three following days. The weekday windows are also shown by connecting stripes 99 each connected to the associated date window.

The following is a brief description of the operation of the step circuit the day and date discs. When swinging the balance 2o back and forth, the lever 26 turns the ratchet wheel 2 8 gradually switched and from there via one not

more detailed chain of wheels rotated the hour tube 34 so, that it goes around once every twelve hours. Its four teeth mesh with the internal teeth 46 of the cam ring 4o, that is to say Circulates once in twenty-four hours. When the cam ring 4o passes the position shown in FIG. 3, the date pawl 54 runs off the run-off edge 52 and slides then along the drainage surface 5o. Because of the large gaps between the teeth the internal toothing 46, this movement occurs abruptly under the action of the pressure spring 6o. This sets the date pawl 54 pivoted about the pin 56 and shifted in the slot 5 8. Through the pivoting movement of the ratchet arm 86 is pivoted, the date pawl 7o by the lifting tooth 92, with the retaining lug 88 as a backup for the release position serves. This releases the date ring 6 6 and the subsequent pivoting movement of the switch nose 62 moved forward by one tooth. At approximately the same time, the switching nose 9o of the ratchet arm 86 presses the adjacent one Tooth of the day.sringes 8o and takes it with him. Through the transverse movement the date pawl 54 corresponding to the slot 5, the lifting tooth 9 2 and the retaining lug 88 slide from the date pawl 7o so that it can fall into the next tooth gap of the date ring 66,. The day locking spring 78 the day ring 8o moved into its final position and held there.

In Figs. 7 and J there is another embodiment of the invention shown. Fig. 8 shows a date ring 12o with four number circles, namely a first number circle 122, a second digit circle 124 ·, a third 126 and a
