Description
Technical Field
The invention relates to a timepiece with a first display device and a second display device, having a twenty-four hour wheel which can be driven by a clockwork mechanism in such a way as to be able to rotate once every twenty-four hours about a rotation axis, a switching lever which can be driven in a pivotable manner by the twenty-four hour wheel, the switching lever having switching teeth (Schaltzahn) by means of which a first gear of the first display device and/or a second gear of the second display device can be advanced stepwise.
Background
In this type of timepiece, it is known to advance a single display device step by switching the teeth.
Disclosure of Invention
The invention is based on the object of specifying a timepiece of the type mentioned at the outset, which allows the first display device and the second display device to be advanced in a manner that saves components and installation space.
According to the invention, this object is achieved in that the switching lever has a first switching tooth and a second switching tooth projecting radially, wherein the first switching tooth can be engaged into the first gearwheel in such a way that the first gearwheel advances rotationally about a first axis parallel to the rotational axis, and the second switching tooth can be engaged into the second gearwheel in such a way that the second gearwheel advances rotationally about a second axis parallel to the first axis, wherein the switching lever is guided in such a way that it can rotate through an angle of 360 ° about the rotational axis along a fixed switching curve once every twenty-four hours, and the switching lever is guided radially outward and then radially inward with respect to the rotational axis during rotation, wherein, in a radially inward position of the switching lever, the first switching tooth does not engage with the first gearwheel and the second switching tooth does not engage with the second gearwheel, and the switching lever moves radially outward in a forward rotational movement from the radially inward position, and the engagement of the first switching tooth into the first gearwheel and the engagement of the second switching tooth into the second gearwheel is simultaneously effected with a respective forward step per rotation of the switching lever, so that the switching lever is then moved radially inwards again into a radially inwards position.
With this design, only a single component for advancing the first and second gear wheels is required. Here, the advance of the first gear and the second gear is performed substantially without a time offset. This results in a simple construction which saves components and installation space.
The first switching tooth and the second switching tooth pivot 360 ° on the same switching diameter.
The design according to the invention makes it possible for the gearwheel having a plurality of teeth to continue to rotate through a large angular path as safely as the second gearwheel.
It is avoided that the first gearwheel continues to advance past the second switching tooth and that the second gearwheel continues to advance past the first switching tooth.
The most different display devices of a timepiece can be advanced by the design according to the invention.
Preferably, the first display means is a display means of the day of the week and the second display means is a date display. Here, the first switching tooth is a day of the week switching tooth and the second switching tooth is a date switching tooth. Subsequently, the first gear is a day of the week gear rotatable about an axis about the day of the week and the second gear is a date gear rotatable about a date axis.
A particularly flat construction can be achieved when the switching lever and the first and/or second gear are located in one plane.
The compact design is achieved in that the switching lever is guided such that it can be moved parallel to the twenty-four hour wheel and radially relative to the twenty-four hour wheel.
The design, which also results in a compact construction, is such that the first gearwheel can be arranged directly next to the second gearwheel.
The design resulting in a simple construction is that the switching curve extends parallel to the twenty-four hour wheel and the switching lever is arranged between the twenty-four hour wheel and the switching curve, wherein the switching lever has a first feeler (abtasttft) which is guided along the switching curve and wherein the switching lever has a second feeler which is guided in a radial slot of the twenty-four hour wheel.
A design is sufficient here in which the probe passes through approximately 180 ° during the rotation of the switching lever and the radially outward movement of the probe is against the switching curve. The probe can be removed from the switching curve during a further rotation of the switching lever and its radially inward movement.
Here, the first probe and the second probe can constitute a member extending parallel to the rotation axis of the twenty-four hour wheel in a component-saving manner, the member having a first portion protruding toward the switching bend and a second portion protruding toward the twenty-four hour wheel.
If the first probe of the switching lever, which abuts against the switching curve, is applied to the switching lever by a spring force, a correct guidance of the switching lever is always achieved in the radially outwardly directed movement of the switching lever.
The prestressed spring bracket can exert a force on the switching lever with its end radially inward to the rotational axis of the twenty-four hour wheel, the second end of the spring bracket being arranged opposite the first end fixedly on the other side of the rotational axis at the twenty-four hour wheel.
If the rotational axis of the twenty-four hour wheel projects into a radially oriented guide slot of the switching lever, wherein the rotational axis has a diameter corresponding to the width of the guide slot, the switching lever is guided in a radially displaceable manner with little component expenditure at two guide positions spaced apart from one another in the radial direction.
Preferably, the first switching tooth and the second switching tooth are arranged at the switching lever at a determined distance from each other in the direction of rotation of the switching lever.
In order to ensure the position of the first and/or second gearwheel, respectively, which is to be taken up again after the advance, the first locking element can resiliently snap into the tooth grooves of the first gearwheel and/or the second locking element can resiliently snap into the tooth grooves of the second gearwheel.
Thereby bringing the first display device and/or the second display device into an oriented position after the advancement.
In this case, the second locking element can be snapped into a tooth groove of the second gear in advance in order to snap the first locking element into a tooth groove of the first gear.
This results in the first locking element being slightly advanced from the position of the snap-in into the first gear wheel after the second locking element has completed the snap-in into the tooth gap of the second gear wheel. Thus, if the second locking member completes the latching, the adjacent teeth of the second gear wheel continue to rotate the switching lever from behind, thereby achieving a sufficient path to push the first gear wheel past the latching point of its first locking member. Thereby, the first display device and the second display device are simultaneously latched.
In addition, the second locking element, with the second locking element engaged, provides the energy for latching the first gearwheel.

Detailed Description
The day of the week and date display mechanism of the timepiece shown in the drawings has a twenty-four hour wheel 1 which can be driven by a not shown clockwork mechanism in such a way as to be able to rotate one revolution about a rotation axis 2 every twenty-four hours.
The switching lever 4 is arranged in such a way that it can be moved radially parallel to the surface 3 of the twenty-four hour wheel 1.
The switching lever 4 has, at its radially inner end region, a radially oriented guide slot 5, which passes through the rotary shaft 2, wherein the width of the guide slot 5 corresponds to the diameter of the rotary shaft 2.
The switching lever 4 has, at its radially outer end region, a probe 6 parallel to the axis of rotation 2, which has a first portion 7 oriented away from the twenty-four hour wheel 1 and a second portion 8 oriented toward the twenty-four hour wheel 1.
The probe 6 projects with its second part 8 into a radial slot 9 in the twenty-four hour wheel 1, wherein the slot 9 with the gap has a width corresponding to the diameter of the probe 6.
The first part 7 of the probe 6 rests radially inward by means of a prestressed spring support 10 against the rotational axis 2 of the twenty-four hour wheel 1 at a switching bend 13. The spring bracket 10 is arranged with one end thereof fixedly at the switching lever 4, is guided arcuately about the rotational axis 2 and is arranged with a second end thereof diametrically fixedly on the other side of the rotational axis 2 at the twenty-four hour wheel 1 with respect to the first end.
The switching curve 13 extends at an angle of 360 ° and is fastened to a fixed switching profile bar 14 in such a way that the first part 7 of the probe 6 can be submerged under the switching profile bar 14. It is sufficient here for the probe 6 to pass through only approximately 180 ° during the rotation of the switching lever 4 and for the radially outwardly directed movement of the probe to bear against the switching curve 13. During the further rotation of the switching lever 4 and its radially inward movement, the probe 6 can be removed from the switching curve 13.
The switching lever 4 has a date switching tooth 11 and a day of the week switching tooth 12, which project radially from the radially outer annular contour of the switching lever 4 in the counterclockwise direction at a defined mutual distance.
A date gear wheel 16 having thirty-one teeth is rotatably supported about a date shaft 17 parallel to the rotational axis 2 of the twenty-four hour wheel 1, and a day-of-week gear wheel 18 having seven teeth, which is configured in a star shape of a day-of-week, is rotatably supported about a day-of-week shaft 15 parallel to the rotational axis 2 of the twenty-four hour wheel 1.
The switching lever 4, the date gear 16 and the day of the week gear 18 are located in one plane and are arranged relative to each other such that, in a radially outward position of the switching lever 4, the date switching tooth 11 meshes into a tooth slot of the date gear 16 and at the same time the day of the week switching tooth 12 meshes into a tooth slot of the day of the week gear 18.
The date gear 16 and the day of the week gear 18 are advanced by one tooth portion by the advancing rotational movement of the twenty-four hour wheel 1 and the switching lever 4, the date switching tooth 11 again protrudes from the tooth groove of the date gear 16 and the day of the week switching tooth 12 again protrudes from the tooth groove of the day of the week gear 18 before the subsequent radially inward movement of the switching lever 4.
The date gear 16 directly or indirectly drives a date display element, not shown, and the day of the week gear 18 directly or indirectly drives a day of the week display element, not shown.
In the embodiment of fig. 7 and 8 there is a date locking member 19 which can snap elastically into the toothing of the date gear wheel 16. The day of the week locking member 20 can resiliently snap into the splines of the day of the week gear 18.
These gears are held in their correct rest position by resilient snap-in the date gear 16 and the day of the week gear 18.
Furthermore, in the embodiment of fig. 7 and 8, the snapping in of the date lock 20 into the toothing of the gear wheel 18 on the day of the week is preceded by the snapping in of the date lock into the toothing of the date gear wheel 16.
Next, the display mechanism for the day of the week and the date display mechanism shown will be described.
The twenty-four hour wheel 1 rotates once in twenty-four hours in the counterclockwise direction.
As shown in fig. 1, the twenty-four hour wheel 1 engages the switching lever 4 around the rotation axis 2 via the elongated hole 9 and the probe 6. In this position, the switch lever 4 is located radially inward thereof so that the day of the week switch tooth 12 does not mesh with the day of the week gear 18 and the date switch tooth 11 does not mesh with the date gear 16.
As the twenty-four hour wheel 1 continues to rotate according to fig. 2, the probe 6 slides along the switching curve 13. In this case, the switching lever 4 is moved radially outward and the spring bracket 10 continues to be tensioned. The date switching tooth 11 reaches near the date gear 16 and the day of the week switching tooth 12 reaches near the day of the week gear 18.
When the twenty-four hour wheel 1 continues to rotate according to fig. 3, the spring bracket 10 is tensioned to the maximum extent, since the probe reaches the maximum deflection point on the switching curve 13.
At this moment, the switching lever 4 starts to rotate the date gear 16 through the date switching tooth 11 and thus advances the date display device. The day of the week gear 18 is rotated by the day of the week switching tooth 12 and thus advances the day of the week display device later.
The advancement of the day of the week gear 18 and the date gear 16 can also be carried out simultaneously depending on the spacing between the date switching tooth 11 and the day of the week switching tooth 12.
When the twenty-four hour wheel 1 continues to rotate according to fig. 5, the approximately maximum radial deflection of the date gear 16 and the gear 18 of the day of the week with respect to its previous rest position is shown. When the twenty-four hour wheel 1 continues to rotate, the date switching tooth 11 and the day of the week switching tooth 12 move again in the direction toward the rotation shaft 2 and the stress of the spring bracket 10 decreases.
In the position shown in fig. 6, it can be seen that the switching lever 4 can be lowered with the date switching tooth 11 and the day of the week switching tooth 12 and the feeler 6 under the freely milled switching contour lever 14. A rotation of the switching lever 4 through 360 ° can thus be achieved. The date switching tooth 11 passes through the gear 18 for one day of the week with sufficient clearance to make it unable to switch.
The day of the week display mechanism and the date display mechanism of the timepiece shown also operate in opposite rotational directions, so that the day of the week and the date can also be corrected backwards, for example by the crown.
The second embodiment shown in fig. 7 and 8 shows a day and date display mechanism in the week of a two-shift timepiece.
Parts corresponding to those in the embodiment of figures 1 to 6 are labelled with the same reference numerals.
A date lock 19 and a day of the week lock 20 are also provided, wherein the date lock 19 is resiliently snap-engageable into the splines of the date gear 16 in the rest position of the date gear 16, and the day of the week lock 20 is resiliently snap-engageable into the splines of the day of the week gear 18 in the rest position of the day of the week gear 18, thereby retaining these gears in the oriented position in the rest position.
The date gear 16 is latched at the time point shown in fig. 7. At the same point in time, the gear 18 on the day of the week is slightly ahead of its latch point. The latch point on the day of the week always lags slightly behind the latch point on the date.
If date locking member 19 completes the click-in into the tooth slot of date gear 16 according to fig. 8, the adjacent tooth of date gear 16 continues to rotate the switching lever from behind, so that a sufficient path is achieved to push gear 18 for the day of the week past its click-in point. Thus, the day of the week display and the date display snap lock at the same instant. The gap between the probe 6 and the elongated hole 9 is fully utilized in this process.
