Definitions

  • the invention relates to a date display of a watch, in particular a wristwatch, with a date drive that can be driven by the clockwork, by means of which a single disk can be driven with one step per day and a tens disk with one step per 10 days, evenly distributed in a concentric circle , approximately radially directed on the surface of the one-disc numbers from 0 to 9 or a multiple thereof, with uniformly distributed in a concentric circle, approximately radially arranged on the surface of the tens disc from 1 to 3 and a blank or a multiple Of which, the tens digits and the empty space each have a continuous window corresponding to a digit size in the tens disk, with such an arrangement of the ones disk and the tens disk in such a parallel manner that the ones and tens disk are in an area of a display position cover, in the display position a tens digit and a one digit visible through one of the windows of a two-digit number can be represented, which is visible through a date window
  • a date display of a watch which has a single disk designed as a disk ring and a tens disk arranged radially within the disk ring of the single disk in the same plane.
  • the ones digits of the ones disk and the tens digits of the tens disk are arranged tangentially directed on the disks.
  • the one and ten disks must also be large, the size of which is limited by the size of the watch case.
  • only an arrangement of the display position in the three o'clock area of the dial is possible.
  • the display position can only be arranged in the three o'clock area of the dial.
  • This object is achieved in that the axis of rotation and the outer circumferential contour of the disc of smaller diameter of tens or
  • One's disk is at least largely arranged within the outer circumferential contour of a disk of larger diameter, that the disk of larger diameter is designed as a disk ring and that the outer circumferential contours of the one disk and tens disk touch approximately.
  • This design enables the disks to be provided with relatively large numbers so that the date can be easily read.
  • the display position can be placed in the peripheral edge area of the disc ring. Since no components of the date display protrude beyond its outer circumferential contour, the display position is thus largely free, but can also be arranged in the edge area of the dial.
  • the drive shaft of the smaller-diameter disk and, if appropriate, the drive shafts of further displays of the clock can also be passed through the disk ring bore of the disk ring without any problems.
  • the date drive is arranged radially within the circumferential contour of the disk ring bore, the installation space required is particularly small.
  • the drive pinion can be shifted from a single program wheel with one step per day via an intermediate wheel, with a step-by-step break of one step after thirty steps the unit disc is advanced thirty times before the number 1 of the unit disc appears in the display position on the thirty-first of a month. Then there is a pause in progress from one step, since on the following day the number 1 should be displayed again for the first day of the next month.
  • this design one can dispense with a double arrangement of the number 1 on the unit disk and be satisfied with the simple arrangement of the number 1. This either reduces the size of the disc ring or enables the digits to be displayed even larger.
  • the disk of smaller diameter designed as a tens disc
  • the index is advanced to twenty and after the following nine indexing pauses to thirty. After that, only one indexing pause is required, in which the unit's disc from the thirtieth on the thirty-first advances before the cycle starts again.
  • the pinion In order for the tens to be positioned exactly in the intended rest position after advancing, the pinion can be locked in a rest position between two steps by a tens key which resiliently engages its teeth.
  • a small space requirement is achieved in that the single program wheel and the tens program wheel are connected in a rotationally fixed manner to a program drive wheel which can be indexed one step per day by an intermediate wheel.
  • the program drive wheel can be locked in a rest position between two steps by means of a catch that resiliently engages its teeth.
  • the date drive is driven by the clockwork in a simple manner in that the intermediate wheel can be driven by a gear wheel of the clockwork of the clock.
  • the idler gear can be rotatably driven at one revolution per day and have a protruding indexing pin which meshes with the program drive gear. This means that the date drive is decoupled from the clockwork outside of an indexing process.
  • program drive wheel can be incrementally advanced by means of a manually actuatable ratchet, then a manual incremental bridging to the actual date can be carried out in a simple and quick manner for a month with thirty or fewer days.
  • the intermediate wheel In order to position the ones exactly after the indexing in the intended rest position, the intermediate wheel can be locked in a rest position between two steps by a one-way catch resiliently engaging in its teeth.
  • the object is alternatively achieved in that the single disk and tens disk have approximately the same diameter, are arranged coaxially to one another and both disks are designed as disk rings.
  • the date display shown in the figures has a single disk 1 designed as a disk ring, on the surface of which is directed approximately radially inwards, evenly on a concentric circle in the peripheral area the numbers 0 to 9 e.g. are arranged by printing.
  • a tens disk 3 is arranged in a parallel plane above the rotatably mounted single disk 1 so as to be rotatable about an axis of rotation 4.
  • the tens disk 3 is arranged eccentrically to the ones disk that the revolving contours 2 and 5 of the ones disk 1 and the tens disk 3 touch at one point.
  • the tens disk 3 is provided on its surface facing away from the ones disk 1 with approximately radially inward, uniformly on a concentric circle in the peripheral area with the numbers 1 to 3 and an empty space 6.
  • the illustrated digits of the two disks 1 and 3 are positioned parallel to one another in such a way that they show a two-digit number or a ones number with a space 6 in front of them.
  • the tens disc 3 is formed between the adjacent digits or between adjacent digits and empty space 6 with continuous windows 7 larger area than the area occupied by the ones digits. This gives the tens disk 3 an approximately cross-like shape.
  • a date drive 9 is arranged radially within the circumferential contour of the disk ring bore 8. This is driven by a gear wheel 10 of the clockwork, not shown, of the clock, the pointer tube 11, on which the gear wheel 10 is arranged, leading through the disk ring bore 8.
  • An intermediate wheel 12 is driven by the gear wheel 10 at one revolution per 24 hours.
  • the intermediate wheel 12 is provided with an indexing pin 13 projecting axially from its plane, which engages once in 24 hours on a tooth of a program drive wheel 14 provided with 31 teeth and advances it by one tooth.
  • the program drive wheel 14 thus rotates step by step with one revolution in 31 days.
  • a single program wheel 15 and a tens program wheel 16 are connected coaxially and in a sandwich-like manner to the program drive wheel 14. Both the single program wheel 15 and the ten program wheel 16 are provided with a tooth pitch of 62 teeth.
  • an intermediate wheel 17 with six teeth is rotatably drivable, which is coaxial with a drive pinion 18 of larger diameter designed as a link wheel is connected in a rotationally fixed manner.
  • This drive pinion 18 which is likewise formed with six teeth, engages in an internal ring gear 19 with 20 teeth, which is formed on the circumferential contour of the disk ring bore 8.
  • the single disk 1 is thus driven step by step at three revolutions per month.
  • the ones program wheel 15 is at the appropriate point a tooth gap 20 provided by two teeth. This creates a pause in advancement of one step.
  • a pinion 21 with eight teeth can be advanced at one revolution per month, which is connected to the tens disk 3 in a rotationally fixed manner via an axis 22.
  • the axis 22 is guided through the disk ring bore 8.
  • the tens program wheel 16 is provided with a tooth pitch of 62 teeth, but actually has only four teeth, as can be clearly seen in FIG. 3. Between a first tooth 23 and a second tooth 24 there is a first tooth gap 25 of sixteen teeth, which causes a first indexing pause of 8 steps.
  • a fourth tooth gap 30 is formed between the fourth tooth 27 and the first tooth 23, which causes a fourth indexing pause of one step.
  • teeth 23, 24, 26 and 27 cause the dial 10 to advance only from the ninth to the tenth day, from the nineteenth to the twentieth day, from the twenty-ninth to the thirtieth day and from the thirty-first to the first day of a month.
  • a one-way catch 31 engages in the intermediate wheel 17 and a ten-way catch 32 resiliently engages in the pinion 21.
  • the program drive wheel 14 is further movable by a pawl 33 in the advancing direction.
  • the pawl 33 has a two-armed lever which can be pivoted about a pivot axis 34, on one lever arm of which a switching tooth 35 is arranged and the other lever arm of which can be actuated manually against the force of a spring 36.
  • the shift tooth 35 held in the rest position by the spring out of engagement by the program drive wheel 14 is engaged by manual actuation and pivoting of the pawl 33 into the ...
  • the teeth of the program drive wheel 14 brought and switches this by one tooth distance per actuation stroke. This means that the date display can be updated after months with less than thirty-one days.
  • a date window 38 is formed in the edge area, through which the digits of the one and ten disks 3 are shown in large format.
  • not only the one disk 1 but also the tens disk 3 ' is designed as a disk ring.
  • the one and ten disks 3 ' have approximately the same diameter and are arranged coaxially to one another.
  • the circumferential contour of the disk ring bore 39 of the tens disk 3 ' is provided with a toothing for driving the tens disk 3'.
  • This embodiment is also an embodiment of the inventive concept.
  • Figures 7 and 8 show that a date display, as shown in Figure 1, can be installed with a small footprint even with clocks with a wide variety of display scales.
  • the dial 40 shown in FIG. 7 has, in addition to the date window 51, a power reserve display 42, a time display 43 for hours and minutes and a separate second display 44.
