Definitions

  • the invention relates to a date display of a watch with a ring-shaped display scale representing the days of the month, on which the respective day of the month can be displayed by a pointer, the pointer being movably drivable by the clockwork of the watch or by means of a crown along the display scale.
  • Such a date display has the disadvantage that it is not possible to have a special desired date such as to indicate the start of the holiday, a birthday or the wedding day and the approaching of this desired date.
  • This object is achieved in that the display scale on one in or against the direction of movement of the pointer movably drivable number ring is arranged.
  • the display scale can be moved so that the desired date is in a special position. This can be a fixed mark or the 12 o'clock position of an analog clock.
  • the dial ring concentrically surrounds a circular time dial of the watch.
  • the scale ring is rotatably mounted on the housing of the watch and / or on a component of the watch which is fixed to the housing.
  • the radially outer circumferential edge of the scale ring can protrude into a correspondingly shaped, radially circumferential ring groove of the housing and / or of the component fixed to the housing, which is open towards the scale ring.
  • the scale ring can be driven to be manually movable.
  • the scale ring can be driven in a simple manner by a drive device that can be driven by means of an adjusting bolt that can be moved toward the scale ring, wherein the adjusting bolt can preferably be moved radially toward the scale ring.
  • the adjusting bolt can be slidably mounted in a housing opening and protrude from the housing with one end for manual actuation.
  • a more favorable storage is obtained if the adjusting bolt is slidably mounted in a guide sleeve fixedly arranged in the housing opening.
  • the adjusting bolt can have a pusher cap on its end protruding from the housing.
  • the adjusting bolt is spring-loaded towards the exterior of the housing, it is reset and held in the rest position after actuation.
  • a movement of the scale ring can take place in that the scale ring is provided with a spur gear, in whose tooth gaps a tooth of the drive device can be moved.
  • the scale ring is moved by the ramp-like sliding of the tooth along a flank of the tooth gap.
  • the spur gear preferably has radially outwardly directed teeth, the tooth of the drive device being movable radially towards the spur gear.
  • the spur gear has 31 teeth or a number of teeth that is a multiple of 31.
  • a simple and space-saving design of the drive device results from the fact that the tooth is arranged at the free end of a lever which can be pivoted about an axis and which is acted upon by a spring in the coupling direction of the tooth from the tooth gaps of the spur gear.
  • the tooth can be arranged on the free end of a lever arm of a two-armed lever which can be pivoted about an axis and the second lever arm can be acted upon by a spring in the decoupling direction of the tooth from the tooth gap of the spur gear.
  • the lever can arch along in a space-saving manner extend the circumference of the spur gear.
  • the spring is the free end of the second lever arm, which is designed as a spring arm and is supported on the housing radially outward under prestress.
  • this or the lever arm can be moved by the adjusting bolt in the coupling direction of the tooth in a tooth gap of the spur gear.
  • the second lever arm has a holding tooth that can be moved into a tooth gap of the spur gear, then this holding tooth is in a tooth gap in the rest position due to the spring action of the lever and secures the scale ring against automatic adjustment.
  • the distance between the tooth and the holding tooth in the circumferential direction of the spur gear is larger or smaller than a whole multiple of the tooth parts and the spur gear.
  • the scale ring is moved further in two partial steps when the adjusting bolt is lifted .
  • the first sub-step is brought about by the engagement of the tooth in a tooth gap, while the second sub-step is carried out by the subsequent engagement of the holding tooth in a tooth gap.
  • the direction of rotation is determined by the fact that the distance between the axis and the tooth is a multiple of the tooth pitch and more than 0.5 times and or less than 0.5 times the tooth pitch.
  • the one interacting with the tooth gaps can Tip of the holding tooth have a larger angle than the tooth gaps.
  • the tip of the tooth interacting with the tooth gaps has a smaller angle than the tooth gaps.
  • the clock shown in Figure 1 is an analog clock with a circular time dial 1, which is enclosed by a scale ring 2 of a date display.
  • a display scale 3 with the numbers 1 to 31 is arranged on the scale ring 2.
  • the hour hand 5, minute hand 6 and second hand 7 are rotatably arranged on pointer shafts or pointer tubes 4.
  • a pointer 8 of the date display is arranged rotatable about the same axis, but on the side of the time dial 1 facing away from an observer. This pointer 8 extends with its free end through an annular gap between time dial 1 and dial ring 2 to the visible side of dial ring 2 and is fork-shaped there. The each The number between the two prongs of the fork is the current date.
  • the pointer 8 can also be adjusted via a gear, not shown. A normal advancement of the pointer 8 per day takes place through the clockwork of the clock, also not shown.
  • the dial ring 2 with its radially outer circumferential edge 10 is rotatably mounted in a corresponding annular groove 11 of the housing 12 of the watch, which is open toward the dial ring 2.
  • a two-armed lever 14 is arranged in a circumferential annular groove 13, which is remote from the observer and is formed and is pivotable about an axis 15 fixed to the housing and parallel to the axis of rotation of the pointer 8.
  • the spring 14 acts on the second lever arm 20 radially to the axis of rotation of the pointer 8 and the lever 14 is acted upon from the tooth gaps 18 in the decoupling direction of the tooth 17.
  • the spring is the free end of the second lever arm 20, which is designed as a spring arm 21 and is supported on the housing 12 radially outward under prestress.
  • the lever arm 16 can be acted upon radially toward the spur gear 19 in the region of the tooth 17 by the one free end of an adjusting bolt 23.
  • the adjusting pin 23 is slidably mounted in a guide sleeve 25 which leads radially outwards and is fixedly arranged in a corresponding housing opening 24.
  • the adjusting bolt 23 is provided with a cup-shaped push cap 26 which engages over the outwardly directed end of the guide sleeve 25.
  • a compression spring 27 arranged under pretension between the presser cap 26 and the guide sleeve 25, the adjusting bolt 23 is held in its radially outer end position when the presser cap 26 is not actuated.
  • the free end of the pot-shaped edge of the presser cap 26 engages around a radially outwardly directed peripheral edge 28 of the guide sleeve 25 and thus limits a movement of the adjusting bolt 23 radially outwards.
  • a driver 29 Extending into the path of movement of the inward end of the adjusting bolt 23, parallel to the axis 15, is a driver 29 which is firmly connected to the lever arm 16 in the region of the tooth 17 and via which, when the adjusting bolt 23 moves radially inward, the lever 14 until the tooth 17 engages is pivoted in a tooth gap 18.
  • the distance between the axis 15 and the tooth 17 is 9 times the tooth pitch of the spur gear 19 plus 1/3 of a tooth pitch, while the distance between the axis 15 and the holding tooth 22 is 6 times the tooth pitch.
  • the spring arm 21 moves the retaining tooth 22 from its uncoupling position shown with a broken line into the tooth gap, as a result of which the retaining tooth 22 on a tooth flank slides along the scale ring 2 in a counterclockwise direction until the movement initiated by tooth 17 for adjustment to complete an entire tooth division.
  • the number of teeth of the spur gear 12 is twice that of 31 in the exemplary embodiment, so that a double actuation of the lever 14 is required to adjust the scale ring 2 by one day.
  • This adjustment allows the scale ring 2 to move into a special position with a certain date, e.g. the 12 o'clock position. Accordingly, the pointer 8 must then be corrected to the current date by means of the crown 9. Now you can always see the day's distance from the current date to a desired date set in the special position at a glance.
