Description: [0001] The invention relates to a second-jump device of a timepiece having a barrel from which a first gear train leads to an escapement which has an escape wheel rotatably mounted on a rotatably mounted escape wheel shaft and an armature which is arranged downstream of a vibration system one of the barrel to rotatably arranged on a second hand second wheel seconds wheel arranged second gear train, wherein the second gear has a rotatably mounted on a rotatably mounted jump shaft rotatably mounted jump gear and the jump shaft has a radially protruding jump lever, with its free end in a gap a star wheel engages which is rotatably mounted on a star wheel shaft of a wheel of the first gear train, wherein by the rotation of the arranged on the star wheel shaft of the jump lever every second once to engage in a further gap of the star wheel for turning free is ebbar, whereby under the force of the barrel, the second gear train is further rotatable by a second division of the second wheel.
The object of the invention is to provide a second jump device of a clock of the type mentioned, which requires a few components and a small space requirement and in which the escapement is supplied with a largely constant force.
This object is achieved according to the invention that between a Speicherantriebsrad and a Speicherabtriebsrad the first gear a biased buffer is arranged, the bias voltage can be re-tensioned by the drive of the barrel, said arranged on the star wheel a wheel between the Speicherabtriebsrad and the escape wheel arranged wheel of the first gear train is.
The barrel is its moment on the second gear to the circumferential radially protruding jump lever on. Likewise, the barrel continues its moment via the first gear train to the intermediate store, from which in turn a transfer of the torque stored therein to the escape wheel of the escapement takes place. The jump lever is prevented by the firmly connected to the escape wheel shaft star wheel on further rotation, which in turn prevents the second gear train and the barrel and the first gear to the cache on further rotation. By the force of the buffer but the Speicherabtriebsrad and driven by this leading to the escape wheel further part of the first gear train under partial relaxation of the buffer and thus supplies the escapement with power without interruption.
Due to the uniform rotation of the wheel arranged on the star wheel and thus also arranged on the star wheel shaft star wheel, the star wheel regularly every second the jump lever free. The jump lever and with it the jump pinion then turn to the stop of the jump lever on the next tooth of the star wheel. As a result, on the one hand, the second hand arranged on the second wheel shaft advances by exactly one second pitch. On the other hand, this also turns the barrel to a corresponding step, which re-tensioned according to the Speicherantriebsrad the buffer according to the previously occurred Teilentspannung. In this case, the amount by which the buffer is retensioned corresponds exactly to the amount that is taken between two seconds jumps to supply the oscillating system.
The arrangement of the buffer in the first gear train between the barrel and the escape wheel leads in conjunction with the regular retightening of the buffer to the fact that the escapement is supplied with substantially the same force. Since each spring depending on the relaxed way of a fluctuation of the spring force and the fluctuation of the spring force of the buffer but is significantly lower than the fluctuation of the spring force of the barrel, the application of force to the escapement is largely the same.
The clock of Nachspannens results with the second jump to every second. This relatively frequent retightening causes the measure of tensioning and relaxing the buffer in a narrow range of the spring characteristic of the buffer is small and thus the variation of the spring force of the buffer is kept low, so thus a constant-force drive is given.
The second jump device fulfills two functions, on the one hand the jumping of the second hand in the second cycle and on the other hand, the clocking for tensioning the buffer also in the second cycle. This leads to a structure with a significantly reduced number of components and a much smaller required space.
To a small number of components and a small space, it continues, if the star wheel is the escape wheel shaft.
The Speicherantriebsrad can be rotatably driven directly and indirectly from the barrel to a latch axis and the Speicherabtriebsrad coaxial with the Speicherantriebsrad freely rotatably, between the Speicherantriebsrad and the Speicherabtriebsrad a buffer forming the spring is arranged.
The positioning of the buffer in the first gear near the barrel leads due to the speeds in this area to the fact that during a Nachspannzyklus the buffer is stretched and relaxed only by a very small amount, resulting in a largely constant power supply of the escapement. A positioning of the buffer in the first gear near the barrel means that the cache is either directly downstream of the barrel or only one or two wheels of the first gear train between barrel and buffer are arranged.
In this case, only a small space is required if the spring is a latch axis enclosing coil spring, which is fixedly connected at one end radially closer to the intermediate storage axis with the Speicherabtriebsrad and with its other end radially remote from the latch axis with the Speicherantriebsrad.
The Speicherantriebsrad may have a radially outwardly extending spiral carrier, at its radially outer region, the outer end of the coil spring is attached.
Is the buffer forming the spring operated in a range of small slope of its spring characteristic between its bias and its increased bias, so that the power fluctuation is kept low.
For minute display, the first gear train and / or the second gear train can have a minute wheel rotatably mounted on a minute wheel shaft carrying a minute hand.
For the barrel close arrangement of the cache can be rotatably driven in the first gear of the barrel a minute wheel and the minute wheel a Kleinbodenrad, wherein the Speicherabtriebsrad the cache is the Kleinbodenrad.
To drive the jump lever can be rotatably driven by the second wheel of the second gear train an intermediate pinion, which is arranged on an intermediate pinion shaft rotatably carries an intermediate wheel, from which the arranged on the jump shaft jump pinion is rotatably driven.
An embodiment of the invention is illustrated in the drawing and will be described in more detail below. Show it
Fig. 1 is a plan view of a second jump device
FIG. 3 is a side view of a second gear train of the second jump device of FIG. 1. FIG.
The illustrated seconds jump device of a clock has a barrel 1 with a ring gear 2, in which both a first minute drive 3 of a first gear train 4 and a second minute drive 5 of a second gear train 6 engage.
A coaxial fixedly connected to the first minute engine 3 first minute wheel 7 engages in a designed as a pinion Speicherantriebsrad 8, which has a radially outwardly projecting spiral carrier 9.
On the spiral carrier 9, the outer end of a buffer forming a spiral spring 10 is fixed, which encloses a storage drive wheel 8 coaxial intermediate storage axis 11.
To the buffer axis 11 is a Speicherabtriebsrad 12 freely rotatably mounted on the radially near the intermediate storage axis 11, the inner end of the coil spring 10 is fixed, which is under a certain bias.
The Speicherabtriebsrad 12 drives a first second drive 13 coaxial with the first second drive 13 fixedly connected first second wheel 14, which in turn engages in a rotatably mounted on an escape wheel 15 wheel 16. On the escape wheel shaft 15 is also an escape wheel 17 of an escapement 20 is arranged, which further comprises an armature 18, wherein the escapement is arranged as a vibrating system a balance 19.
The second minute drive 5 of the second gear train 6 is firmly fixed coaxially with a second minute wheel 33, which engages in a small ground gear 21 of a coaxial permanently connected to it Kleinbodenrades 22, which in turn engages in a second second drive 23, which on a Second wheel 24 is fixed.
The second wheel shaft 24 also carries a rotationally fixed with a revolution per minute rotating second second wheel 25 and a second hand, not shown.
The second second wheel 25 engages in an intermediate pinion 26, which is coaxially rotatably connected to an intermediate gear 27, which in turn engages in a arranged on a jump shaft 28 jump pinion 29. Furthermore, the jump shaft 28 has a radially protruding jump lever 30 which engages with its free end in one of the gaps of a five teeth 31 having star wheel 32.
The star wheel 32 is rotatably mounted on the escape wheel shaft 15.
From the coil spring 10, the escape wheel 17 is acted upon by a torque, so that the escape wheel shaft 15 rotates with one revolution per five seconds.
By this rotation, the star wheel 32 also rotates with one revolution per five seconds, whereby each second of the jump lever 30 is released from the star wheel 32 and can perform a revolution, and then intervene in the adjacent gap of the star wheel 32 again.
In this case, the second gear train 6, which is normally blocked by the engaging in a gap of the star wheel 32 jump lever 30, under the moment load by the barrel 1 continue briefly and further rotate the second shaft 24 by 1/60 turn, so that so too the second hand is jumped by one second division.
Since this rotational movement is carried out on the second gear train 6 and the barrel 1, this is about the first minute engine 3, the first minute wheel 7 and the Speicherantriebsrad 8, the coil spring 9 every second and thus at short intervals so always is re-tensioned that the escapement 20 is supplied with almost constant force. This is also because only a short and low slope having area of the spring characteristic of the coil spring 10 is used.
