Description

Clock, control element and method for operating a control device with high control quality

Technical area

The invention relates to a control element, which drives the frequency-giving element with constant energy, and a method for operating such.

State of the art

A mechanical movement has a main energy storage, e.g. a spiral spring, which drives the wheels of the movement.

At the same time, the movement has a control element that brakes the wheel train and releases it at a preset frequency for the further rotation by one step. The control element has a frequency-giving element, e.g. a restlessness, which controls an inhibition, which in the frequency predetermined by the element giving the frequency with the

Gears connected escapement wheel for further rotation by one step. At the same time, the escape wheel transmits the necessary energy from the energy store to the frequency-giving element so that it can maintain a constant oscillation.

The problem now is that the main energy storage, for example, a drive spring, depending on the state of charge more or less force on the wheels and thus more or less energy transfers to the restlessness. This leads to a varying over time

Power supply of the frequency-giving element of the movement. Also the very temperature dependent viscosity of the lubrication of the

The wheel-train therefore has an influence on the energy transmitted to the unrest. The prior art shows the following solutions for this

Problem.

CH353679 shows a Remontoire, the main energy storage a first coil spring and as a buffer a second smaller, on having the escape wheel mounted coil spring. This second

Spiral spring can store less energy and must therefore be re-tensioned at shorter intervals, resulting in a faster equalization of energy fluctuations, so that the energy transferred to the unrest is more constant.

CH292465 shows a Force Constant escapement, designed as a chronometer escapement, which has a coil spring as a buffer for the energy to be transmitted to the unrest. The buffer allows again to transfer a more constant energy to the unrest. However, chronometer inhibitors have the disadvantage that such movements are not self-starting and a pulse transmission takes place only in one direction.

DE1293696 also shows a chronometer escapement which has a leaf spring coupled to a fork engaging in a restlessness as a buffer for the energy to be transmitted to the agitation. The leaf spring can bounce back and forth between a second-order bend line having a discrete high energy state and a first-order bend line with a discrete low energy state. When a driver of agitation enters into contact with the fork, the agitation moves the fork so far that it moves the leaf spring over the potential higher discrete state energy peak and the stored energy is released onto the agitation. Thus, only the stored energy of the leaf spring is transmitted to the restlessness and the vibration of the restlessness is independent of the drive spring. Again, there are the same disadvantages of the previously described chronometer escapement.

At the same time, the energy released by the rest of the leaf spring and the necessary release force of the leaf spring are dependent on the length of the leaf spring and on its modulus of elasticity. At a

Temperature change but change the length and / or the

Young's modulus of the leaf spring. Thus, this clock works only in a certain temperature range, while in others

Temperature ranges are the speed of the clock and the

Triggering force of the leaf spring changed by the restlessness. The latter causes the leaf spring already at shaking the clock mistakenly triggers or that the release force of the leaf spring slows down the restlessness unnecessarily. In addition, the dependence of the energy of the leaf spring has the disadvantage that the calibration of the clock is very difficult.

WO9964936 discloses a control organ having a leaf spring which can reciprocate between a fourth-order bending line having a discrete high energy state and a second-order bending line having a discrete low energy state. The leaf spring is mounted between two fixed points, that during a movement of a coupled to the leaf spring fork by a driver of a restlessness, the leaf spring with the bending line fourth order on the

Potentialberg is moved and the stored energy of the leaf spring is released. The released energy of the leaf spring is transferred to the fork and the restlessness. The inhibition has two

Escapement wheels, which are each coupled to the wheel train, and a chock on. The Hemmstück is not frictionally connected to the fork, but coupled with the leaf spring. During the

Jumping the leaf spring curve line and the energy transfer to the restlessness is the inhibitor piece by the shape change of

Leaf spring moved from the inhibitory position and that of the

Escapement braked escapement wheel released. The released escapement wheel rotates by the force of the main drive spring

Inhibitor until the next inhibitory position. By the rotation of the Hemmstücks the coupled leaf spring is charged again by the bending line of the second order in the bending line fourth order. The leaf spring of this regulatory body has the same problems

Temperature dependence as the previously described DE1293696.

At the same time here is problematic that the leaf spring is charged during the energy release on the rest again by the inhibitor. This leads to a disruption of the energy release on the restlessness and thus prevents a constant release of energy to the restlessness. Another disadvantage of this movement is the very complex structure.

EP2706416 now discloses a simplification of the construction of WO9964936. Here, the escapement consists of an anchor with two Pallets for escaping an escape wheel. The anchor is coupled via a leaf spring with an interfering fork. The leaf spring can bounce back and forth between a second-order bend line having a discrete high energy state and a first-order bend line with a discrete low energy state. The ends of the leaf spring are each mounted symmetrically about the axis of rotation of the fork and the armature, so that a rotation of the armature and / or the fork lead to a bending line change of the leaf spring. When the fork is moved by the driver of the restlessness, the leaf spring with the second order bending line is moved over the potential mountain and the stored energy of the leaf spring is released. The thus released energy of the leaf spring is transmitted by the caused rotation of the fork on the restlessness. During the jump of the

Blattfederbiegelinie and the energy transfer to the restlessness of the anchor is rotated by the change in shape of the leaf spring. As a result, the armature wheel braked by the armature is released, which further rotates the armature by the force of the main drive spring until it is again in an inhibiting position and the leaf spring again has a second-order bending line. This structure is simpler. Here, too, the charging of the spring takes place during the impulse delivery to the restlessness, whereby the impulse to the disturbance depends again (albeit in lesser masses) on the force of the drive spring. At the same time, the spring arrangement between the armature and the fork has the following disadvantage. With usual sizes for the escape wheel and the anchor, the spring is very short. As a result, the spring is very sensitive in terms of their length and thus difficult to adjust. Alternatively, of course, the distance between the fork and anchor can be increased, but this would lead to an undesirable increase in the control element. This would have in addition to the required space requirement in addition a negative effect on the inertia during the

Impulse transmission accelerated components of the control element.

At the same time, the leaf spring has the same adjustment and

Temperature problems as described in DE1293696.

Another problem common inhibitions with a restlessness is that the coupling rotation angle range in which the restlessness Triggering and the subsequent energy consumption with the fork plays together, is relatively large. An anchor escapement usually has a coupling rotation angle range of approx. 50 °, which can be reduced a bit with high-quality execution. A perfect oscillation, on the other hand, receives a constant punctual impulse in the rest point of restlessness, which supplies the lost frictional energy each time it passes through the rest point. The bigger the

Coupling rotation angle range of an inhibition, the more the perfect vibration of restlessness is disturbed by the energy exchange between fork and restlessness. In addition, the trip resistance or the armature inhibition pulse is different depending on the direction of rotation, which is also a disturbance to the vibration.

Although chronometer inhibitors, as described above, allow to reduce this coupling rotation angle range, but at the same time have the disadvantage that the unrest in one direction only

is driven and thus also represents a disturbance to the vibration. For coaxial inhibition, as e.g. in EP1045297A1, coupling rotational angle ranges up to 30 ° are known. The unrest is driven here in both directions. However, the pulse and / or the tripping resistor are due to the different

Drive trains very different depending on the direction of rotation. In any case, there are no inhibitions that manage to realize a smaller angle of rotation than 30 °. This is due to the large mass inertia of the movement, which prevents the impulse from the fork to the disturbance can be transmitted at a smaller angle. Even if the

Mass inertia would be reduced by light materials, so increases at smaller angles, the risk that the ellipse of unrest no longer swing cleanly into or out of the fork. In addition, due to the inertia, the area in which the fork is only dragged increases to the same extent, reducing the area in which the actual momentum is transmitted. Therefore, there are no inhibitions in the prior art with coupling rotational angle ranges smaller than 30 °.

Furthermore, it is known from CH341764 to vary the thickness of the driving coil spring over its longitudinal axis. Also is off DE102013106505 the thickness of a vibrating coil spring of a restless about the longitudinal axis to vary.

Presentation of the invention

It is an object of the invention to invent a control device which solves the problems of the prior art.

It is an object of the invention to find a control device which drives the frequency-giving element with a particularly high control quality.

In one embodiment, this goal is solved by a control organ of a clock. The control element has an escape wheel, a restlessness with a first direction of rotation and a second direction of rotation, a blocker for inhibiting the degree of inhibition, and a bistable one

Latch formed for each of the first and second

Direction of restlessness to release a cached energy to the restlessness and to absorb energy. The control element is characterized by the fact that the energy intake of the

Caching takes place after the completion of energy release on the restlessness.

In one embodiment, this object is achieved by a method for controlling a movement. The method has the following steps per direction of restlessness. Delivering a cached in a bistable energy storage on the restlessness. Picking up energy in the cache. The method is characterized in that the energy consumption of the

Caching takes place after the completion of energy release on the restlessness.

Through this temporal separation of energy intake and

Energy release of the buffer can be a constant energy delivery to the restlessness, which has a particularly accurate frequency accuracy of the frequency-giving element result. In one embodiment, this goal is achieved by a

Solved control organ of a clock that has an escapement wheel, a restlessness, a chock and an energy transfer agent in one

Coupling rotation angle range so coupled with the restlessness to be triggered by the restlessness and to give energy to the unrest after the triggering, the coupling rotation angle range is less than 30 °.

In one embodiment, this object is achieved by a method of operating a control organ of a timepiece comprising the steps of: coupling an energy transferring means with restlessness in a rotational angle coupling region, wherein the step of copying comprises triggering the energy transferring means by disturbing and releasing energy from the Energy transfer agent on the

Unrest, wherein the coupling rotational angle range is less than 30 °.

By reducing the coupling rotation angle range below 30 °, the energy transfer is more and more approximated to an ideal impulse, which optimizes the energy transfer. As a result, the restlessness can be driven with less energy. At the same time disturbances of restlessness, e.g. Vibrations, avoided by concentrating the main impulse transmission in the stability point of restlessness. Thus, the control quality of restlessness is increased.

In one embodiment, this object is achieved by a control organ of a watch comprising a gear train with an escapement wheel, restlessness, a stopper engaging the escapement wheel to inhibit rotation of the escapement wheel, and loading means engaging the wheel train for transmitting energy to the wheel train Agitation to maintain the vibration of restlessness.

The separation of the function of inhibiting and the

Pulse transmission from the gear train separated by two in the

Gear engaging means, allows the impulse transmission of the Gears on the unrest regardless of the release of the

Escape wheel to realize by the inhibitor piece. This allows a constant transfer of energy to the restlessness.

In one embodiment, this object is achieved by a regulator of a timepiece comprising a bistable spring for the constant delivery of energy to an oscillator, e.g. a restlessness, having. The thermal length and / or modulus of elasticity of the bistable spring is compensated by a thermal change in length of the bearing points of the spring in a circuit board, that of the spring on the

Oscillator emitted energy remains constant with the temperature.

This solves the problem of high temperature sensitivity of constant force movements using a bistable spring.

In one embodiment, this object is achieved by a regulator of a timepiece comprising a bistable spring for the constant delivery of energy to a regulator, e.g. a restlessness, having. A parameter of the spring determining the local elasticity changes along its longitudinal axis.

As a result, on the one hand, the time behavior of the spring in the triggering and the pulse delivery to the gear regulator can be set much finer than with a spring with constant parameters along the longitudinal axis. At the same time this can be used so that the effect of the extension of the spring with temperature changes has less influence on the pulse delivery and the triggering of the bistable spring.

In one embodiment, this object is achieved by a control organ of a timepiece having an escapement wheel, a restlessness, a chock, and a latch for receiving energy and delivering the cached energy to the perturbation.

In one embodiment, this object is achieved by a method of operating a control organ of a timepiece comprising the steps of: receiving energy in an intermediate memory of the timepiece Control element; Delivering the cached energy from the

Cache on a restlessness of the regulatory body.

Ways to carry out the invention

For the description of the embodiments, a definition of the term "bistable energy storage" is important, for example as an energetic buffer of a clockwork

Energy storage is a buffer with at least two locally stable energy states, the bistable energy storage is separated in the energetically high stable energy state by a potential mountain of the deep stable energy state and passes by supplying a certain amount of energy to overcome the potential mountain in the energetically deep stable energy state and thus the stored energy releases. The point of overcoming the potential mountain is also called the instability point. The low stable energy state can be both a local and a globally stable energy state, whereby any globally stable energy state is always locally stable. The

Terms "lower stable energy state" and "high stable

Energy state "should not be understood absolutely, but only mean that the low stable energy state is lower in energy than the high stable energy state." Bistable is not on two stable

Energy states limited, but means that there can be more than two stable states of energy. Bistable springs, e.g. bistable

Leaf springs are an example of such bistable energy storage. For this purpose, a leaf spring or a leaf spring region of length L is stored between two bearing points of a distance L small, so that forms a bending line between the bearing points with a belly. These

Bending line with a belly represents a first order energy state and is globally stable. By energizing the leaf spring but can also take a bending line with two, three, four, or generally with n bulges (with n-1 curvature changes) with the corresponding

Energy states of the second, third, fourth or general nth order. As the lower stable energy state of the bistable spring, the first order energy state is preferably used, but each higher one

Energy state, e.g. second order, can also be considered more deeply stable

Energy state can be used when more than two stable

Energy conditions exist. The high stable energy state is higher in order than the low stable energy state. A bistable

Leaf spring is thus a leaf spring, which is arranged to accept bending lines of at least two different orders. Of the

First-order energy state of a bistable spring can be achieved both by a first curvature direction and by a second curvature direction

Curved direction be realized. Analogously, an energy state of each order can be realized by a bending line symmetrical to the leaf spring axis. The leaf spring axis is as the between the two

Bearing points stretched line defined. A symmetrical bistable leaf spring is thus defined as a bistable leaf spring which is so

is arranged so that they can accept bending lines of two orders and their mirrored bending lines.

Fig. 1 A to 1 E shows a first embodiment of a control element in various states. The control element has a restlessness 1, a buffer 4, a power transmission means 3, an inhibitor 7, an escape wheel 9 and a clamping piece 5.

The agitation 1 is formed as part of a free inhibition to swing in a certain frequency and serves as a speed regulator for the movement. For this, the restlessness 1 preferably does not have one here

illustrated coil spring with a likewise not shown

Flywheel on. To trigger the inhibition, the restlessness 1 is coupled to the escape wheel 9, and to absorb energy, the restlessness 1 is coupled to the temporary storage 4. Both couplings are achieved in this embodiment via the energy transmission means 3. The coupling means for coupling with the energy transfer means 3 is shown in FIG. 1A. The restlessness 1 or the coupling means of restlessness 1 has a driver 10, which is arranged coaxially to the axis of rotation 12 of the restlessness 1 and rotates with the vibration of the unrest 1 about the axis of rotation 12 of the restlessness 1. This driver 10 is also referred to as ellipse. Within one oscillation period (inverse of the oscillation frequency) of the disturbance 1, the cam 10 moves once in a first rotational direction (eg, clockwise) from a first rotational reversal point to a second rotational reversal point and once in a second rotational direction (eg, counterclockwise) from the second Direction of rotation reversal point back to the first

Rotation reversal point. The rotational angle of the driver 10, in which the restlessness 1 is in the equilibrium position, will be defined below as the dead center or 0 °. The rotation angle range of restlessness 1 or of the driver 10, in which the restlessness 1 with the

Energy transfer means 3 couples, will be referred to as

Coupling rotation angle range can be designated. This is preferably, but not necessarily arranged symmetrically about the rotational angle 0 °. The coupling rotational angle range may become less than 30 ° due to the minimum inertia of the energy transferring means that can be achieved due to the buffer. can be between + 15 ° and -15 ° with symmetrical distribution. As a result, very small coupling rotational angle ranges can be achieved and the control quality of the control element can be improved. Preferably, the coupling rotational angle range is less than or equal to 28 °, preferably less than or equal to 26 °, preferably less than or equal to 24 °, preferably less than or equal to 22 °, preferably less than or equal to 20 °, preferably less than or equal to 18 °,

preferably less than or equal to 16 °, preferably less than or equal to 14 °,

preferably less than or equal to 12 °, preferably less than or equal to 10 °,

preferably less than or equal to 8 °. Preferably, the maximum

Coupling angle of rotation from the resting point of rest less than 15 °, less than or equal to 14 °, preferably less than or equal to 13 °, preferably less than or equal to 12 °, preferably less than or equal to 1 1 °, preferably less than or equal to 10 °, preferably less than or equal to 9 °, preferably less than or equal 8 °,

preferably less than or equal to 7 °, preferably less than or equal to 6 °,

preferably less than or equal to 5 °, preferably less than or equal to

4 °. Preferably, a coupling of the unrest 1 with the Energy transmission means 3 twice per oscillation period, ie for each direction of rotation once when the driver 10 the

Passage coupling angle range. In a prototype, a restlessness 1 with a coupling angular range of 5.2 ° was achieved. In this prototype, the first 2.2 ° for the release of the

Energy transfer means 3 and the buffer 4, 0.3 ° for the stop change of the driver 10 in the power transmission means 3 and 2.7 ° for the energy transfer from the power transmission means 3 to the driver 10 is required. This corresponds approximately to an ideal impulse in the rest position of unrest 1. Outside the

Coupling rotation angle range, the agitation 1 or the driver 10 is not coupled to the energy transmission means 3. Of the

Rotation angle range of the period of oscillation of the driver 10 outside the coupling rotation angle range is also referred to as supplementary sheet. Although agitation 1 has been used in this embodiment, gait controllers other than agitation 1 may be used.

The buffer 4 is designed to store energy. The temporary storage 4 can continue to transmit 1 energy in the coupling rotation range of the unrest on the unrest 1 to a stable

To guarantee vibration of agitation 1. In this embodiment, the cached energy over the

Energy transfer 3 transmitted to the disturbance 1. Preferably, the buffer 4 is a bistable energy storage, which is in the high stable energy state when the agitation 1 or the driver 10 is located before entering the coupling rotation angle range. When entering the coupling rotation angle range, the disturbance 1 transmits an initial energy to the buffer memory 4, which brings the bistable energy storage device over the potential peak, so that the buffer 4 can transition into the low stable energy state and release the stored energy. In the shown

Embodiment, the latch 4 is a leaf spring,

in particular a bistable leaf spring, in particular a symmetrical bistable leaf spring. The bistable leaf spring 4 shown in the first embodiment is in the high stable energy state in a second order bendline (eg, FIGS. 1A, 1E) and in the low stable energy state in a first order bendline (eg, FIG. 1D). The bistable leaf spring 4 of Fig. 1A is further formed as a symmetrical bistable leaf spring 4, so that the bending line of the leaf spring 4 in the deep stable energy state during the first direction of unrest 1 (Figure 1 D) mirror symmetry with respect to the leaf spring axis to the bending line the leaf spring 4 is in the deep stable energy state during the second rotational direction of the restlessness 1 and / or that the bending line of the leaf spring 4 in the high stable energy state during the first direction of restlessness 1 (FIG. 1A) is mirror-symmetrical with respect to the leaf spring axis to the bending line of FIG Leaf spring 4 in the high stable energy state during the second rotational direction (Fig. 1 E) of the rest 1. The leaf spring 4 is in the illustrated embodiment in Fig. 1A, preferably with a first end, on the rotatably mounted on a circuit board power transmission means 3, and, preferably with a second end, mounted on the rotatably mounted on the board clamping piece 5. Thus, the leaf spring axis of the leaf spring 4 is here by the line between the axis of rotation 1 1 of the lever 3 and the axis of rotation 18 of the

Defined clamping piece. Alternatively, the leaf spring 4 but also at an attachment point or at two attachment points directly on the board are rotatably or firmly attached (see, eg, Fig. 3, 5 or 5). Is spoken in this invention of the coupling of the leaf spring 4 with the energy transfer means 3 or the Hemmstück 7, so it may be both an attachment to this and an attachment of the leaf spring 4 outside this, but with a coupling on this meant. A buffer 4 has the advantage that the necessary energy can be delivered in a very small coupling rotation angle range, since a low mass inertia of a buffer 4 can be much easier reduced than in classical inhibitions. The intermediate memory 4 is furthermore designed such that the process of the energy output from the intermediate memory 4 takes place on the turbulence 1 in the coupling rotational angle range and the subsequent charging of the discharged intermediate memory 4 only from or after the decoupling of the intermediate memory or of the energy transmission means 3 from the restlessness 1 or from the driver 10 can begin. This has the advantage that the energy transmitted to the disturbance 1 from the buffer 4 is constant and is not changed by influences from the escape wheel 9. It is particularly advantageous if the buffer 4 is moved by the restlessness 1 in or shortly before the dead center (the rest position) of the restlessness 1 through the instability point and in the dead center of restlessness 1, the energy release on the unrest begins 1 or the focus the energy delivery is on the unrest 1 in the dead center of restlessness 1. This has the advantage that the influence of the impulse delivery on the restlessness 1 is minimal. With a classic anchor escapement this is not possible reliably. Preferably, the energy for charging the

Latch 4 from the rotation of the gear train, e.g. of

Escapement wheel 9, taken. The force acting in the direction of the leaf spring axis should be determined by the center of the axes of rotation of the

Energy transmission means 3 and the clamping piece 5 run (to produce no length changes to the buffer 4). The

Symmetrical line of the energy transmission means 3, the clamping piece 5 and the Hemmstücks 7 but not with the pulse spring. 4

to match.

The energy transfer means 3 is designed to transfer energy from the buffer 4, or from a charging means formed by the buffer 4 and the clamping piece 5, to the turbulence 1. Preferably, the energy transmission means 3 is designed as a lever which is rotatably mounted about a rotation axis 1 1. Preferably, the axis of rotation 1 1 is arranged parallel / coaxial with the axis of rotation 12 of the turbulence 1. However, the energy transmission means 3 can also be designed differently, e.g. directly through one end of the leaf spring. 4

At a first fulcrum point (coupling point), preferably at a first end of the lever 3, a coupling means is arranged for coupling with the agitation 1. Preferably, the coupling means comprises a fork 14, which is formed in the

Coupling rotational range of restlessness 1 in the driver 10 intervene and so to create a rotary coupling between the restlessness 1 and the lever 3. If the agitation 1 turns, e.g. in the first

Direction of rotation is the driver 10 outside the

Coupling rotation angle range not yet coupled to the lever 3. at Entering the coupling rotational angle range engages the fork 14 in the driver 10 and couples the rotation of the disturbance 1 with the rotation of the lever 3 until the driver 10 exits from the coupling rotation angle range and the lever 3 and the driver 10 decouple again.

As a result, the lever 3 rotates in the direction opposite to the direction of rotation of the rest 1 rotation. The interference means 1 (driver 10) and the energy transmission means 3 (fork 14) described here are just one example of a possible coupling. Additionally or alternatively, other coupling agents may be used. Of the

Safety lever 15 secures the escapement outside of the

Coupling range against unwanted tripping, as is common in Swiss anchor escapement.

The coupling point of the driver 10 with the fork 14 has a first distance from the fulcrum of the disturbance 1. Of the

Coupling point of the fork 14 with the driver 10 has a second distance to the pivot point of the lever 3. The ratio of the second distance to the first distance (second distance divided by the first distance) is usually selected around the 3. At small angles, however, this leads to an increased risk of disturbances, since the angle traveled by the lever 3 is still three times smaller than the angle traveled by the driver 10 in FIG

Angle of rotation coupling area is. Therefore, it is particularly advantageous for small angles, the ratio of the second distance to the first distance less than 2.5, in particular less than 2, in particular less than 1, 5 or even less than 1 to design. This reduces the susceptibility of the interaction of energy transfer means 3 with the restlessness 1.

At a second fulcrum 17, preferably at a second opposite end of the lever 3, the lever 3 is coupled to the buffer 4. The second fulcrum 17 is so

arranged that energy stored in the latch 4 can be converted into a rotational energy of the lever 3, which in turn is transmitted in the coupling rotation angle range of the disturbance 1 to the disturbance 1. For the leaf spring 4, this means that a rotation of Levers 3 leads to a change in the bending line of the leaf spring 4. In the embodiment shown in FIG. 1A, the second fulcrum 17 is arranged on the side of the first fulcrum point opposite to the axis of rotation 11 of the lever 3. However, alternatively, the second fulcrum 17 could also be arranged on the same side of the first fulcrum. The second fulcrum 17 is arranged very close to the axis of rotation 1 1, so that a rotation of the lever 3 mainly leads to a change in the output angle of the leaf spring 4 and only a small translational movement. However, the second fulcrum 17 could also be arranged further away from the axis of rotation 1 1 (see, eg, FIGS. 5 and 6). A symmetrical mounting or coupling of the leaf spring 4 about the axis of rotation 1 1 of the energy transmission means 3 (point symmetry to the axis of rotation 1 1 of the energy transmission means 3) can be used to minimize the bearing pressure of the storage of the energy transfer means 3.

In this example, the energy transmission means 3 is designed as a rotatably mounted lever. Alternatively, that could

Energy transmission means 3 may also be designed differently and e.g. perform a translational movement to the energy of the

Intermediate memory 4 with the rotational movement of the disturbance 1 to couple. Also, it would be possible to directly transfer the energy transfer means 3 as an area, e.g. the end portion of the leaf spring 4 form.

The inhibitor 7 is designed to intervene in the escape wheel 9 inhibiting and every time the unrest 1 the

Passing through or has passed through coupling rotation angle range, the

Escapement 9 for rotation of the escape wheel 9 to release a certain angle of rotation. Unlike the anchor escapement, the inhibitor 7 in the first embodiment is not configured to transmit a rotational energy of the escapement wheel 9 to the agitation. The inhibitor 7 is executed here, for example, as an anchor (without interference with the restlessness 1). The Hemmstück 7 has for engaging in the

Escapement 9 preferably a first pallet 8a and a second

Palette 8b. The first pallet 8a is preferably for inhibiting the

Escape wheel 9 during the falling supplementary arc (in direction Coupling rotational angle range) for the first rotational direction of the disturbance 1 and possibly additionally for the end of the ascending supplementary arc (away from the coupling rotational angle range) in the second rotational direction of the disturbance 1. The second pallet 8b is preferably for

Inhibition of the escapement wheel 9 during the falling

Supplementary arc (in the direction of coupling rotation angle range) for the second direction of the unrest 1 and possibly also for the end of the rising supplementary arc (away from the coupling rotation angle range) in the first direction of rotation of the disturbance 1 formed. The Hemmstück 7 is preferably rotatably mounted on a rotation axis 22. The axis of rotation 22 is e.g. coaxial / parallel to the axis of rotation 12 of the restlessness 1 and / or to a rotational axis 23 of the escapement wheel 9 stored. In the embodiment shown, the inhibitor 7 is between a first

inhibiting position (see, e.g., Fig. 1A) and a second inhibiting position (see, e.g., Fig. 1E). For this purpose, e.g. a first stopper 2a for limiting the rotation of the Hemmstücks 7 in the first rotational direction and a second stop 2b for limiting the rotation of the Hemmstücks 7 arranged in the second rotational direction. These are optional. In this embodiment, the power transmission means 3 and the inhibitor 7 are two independently movable / rotatable parts. The energy transfer means 3 couples with the agitation 1 in the

Coupling rotational angle range. This remains during this coupling

Inhibitor 7 unmoved and the escape wheel 9 inhibited, whereby the pulse output from the latch 4 to the agitation 1 solely from the latch 4 and the energy transfer means 3 depends. The driving force of the escapement wheel 9 and the lubrication of the

Wheel train affect the impulse delivery to the restless 1 thus not.

The Hemmstück 7 has a first stop 24a and a second stop 24b. The first stopper 24a is for limiting the relative rotation of the power transmitting means 3 (in the first

Direction of rotation) to the Hemmstück 7 and the second stop 24 b is formed for limiting the relative rotation of the power transmission means 3 (in the second rotational direction) to the Hemmstück 7. Only when the energy transmission means 3 abuts on the first or second stop 24a or 24b, the inhibitor 7 begins due to inertia the energy transfer means rotation and / or due to the

To rotate residual energy of the buffer 4 and release the escape wheel 9. After the stop of the power transmission means 3 at the first or second stop 24a or 24b, the inhibitor 7 rotates from the first stop 2a to the second stop 2b (or

vice versa). The energy transfer means 3 rotates in one of the stops 24a or 24b befindlich located with the Hemmstück 9, since the leaf spring 4 continues to press the energy transfer means 3 in the posted with one of the stops 24a or 24b position. By doing

Moment of the first stop, the unrest 1 is already from the

Energy transfer means 3 decoupled. Alternatively, the unrest decouples 1 or the driver 10 by the deceleration of the

Power transmission means 3 when striking the first stop 24a or the second stop 24b at the moment of the stop.

This ensures that the restlessness 1 is not influenced by the friction and abutment moments when the escape wheel 9 is released. In this embodiment, the energy transfer means 3 and the Hemmstück 7 are mounted on two different axes of rotation 1 1 and 22. Alternatively, they could also be mounted on the same axis of rotation (but rotatable independently of each other).

The escape wheel 9 is part of the gear train of the movement and rotatably coupled thereto. The gear train is by a

Energy source, e.g. a main drive spring of the clockwork, driven. The escapement wheel 9 of the gear train is coupled with the inhibitor 7 so that it is braked by the engaged inhibitor 7 or

is inhibited and is released upon movement of the Hemmstücks 7 in a predetermined by the gear regulator frequency for the rotation of the certain angle of rotation. Preferably, the escapement wheel 9 is released twice per oscillation period of the disturbance 1 (once for each direction of rotation) and accordingly rotated further twice by the specific angle of rotation. For this purpose, the escape wheel 9 a plurality of teeth 27. These teeth are distributed at regular intervals over the circumference of the escape wheel 9. Each tooth 27 has an inhibiting area 25. This is designed here as a groove into which the pallets 8a and 8b engages when they inhibit the escapement wheel 9. In FIG. 2 shows an alternative embodiment for the inhibiting regions 26. These are here by in the direction of the axis of rotation of the escape wheel 9 (that is, perpendicular to the flat side of the

Hemmungsrads 9) extending projections which abut the pallet 8 a or 8 b, when the escape wheel 9 is inhibited by the Hemmstück 7. In this case it is possible to operate the resting pallets 8a and 8b with their own (or without) lubrication. Alternatively, the inhibition region may be realized by other means or by a flat surface.

The clamping piece 5 is designed to charge the latch 4 with energy. Preferably, the clamping piece 5 engages in the gear train, here in the escape wheel 9, and loads the latch 4 upon rotation of the gear train or the escape wheel 9.

In particular, in the case of bistable energy stores as temporary storage 4, the rotational energy should be sufficient for a rotation of the escape wheel 9 about the determined rotation angle in order to convert the temporary storage 4 from the low stable energy state into the high stable energy state. Preferably, the clamping piece 5 is rotatably mounted about the axis of rotation 18 and engages in the gear train or the escapement 9 so that a rotation of this, causing a rotation of the clamping piece 5. Since the clamping piece 5 is coupled to the buffer 4, this rotation of the clamping piece 5 is transferred to the buffer 4. In the case of a leaf spring 4 causes the rotation of the clamping piece 5, a transfer of the bending line deep (first) order in a bending line high (second) order. With a turn of agitation 1 in the first

Turning direction is released after passing through the coupling rotation range of the rest 1, the escape wheel 9 in the second direction of rotation, causing a rotation of the clamping piece 5 in the second (or alternatively first (for example, Fig. 3, 5 and 6)) direction of rotation. Upon rotation of the rest 1 in the second direction of rotation is after passing through the

Coupling rotation range of restlessness 1, the escape wheel 9 is also released in the second direction of rotation, but this leads to a rotation of the clamping piece 5 in the first (or alternative second) direction of rotation

caused. Thus, the direction of rotation of the clamping piece 5 is alternated for alternate directions of rotation of the chute 1 and each time the Latch 4 recharged. Preferably, the clamping piece 5 has a first pallet 6a and a second pallet 6b. In this case, one of the two pallets 6a or 6b engages in the escape wheel 9.

In Figs. 1A to 1E, the various states of the

Control element of the first embodiment for the first direction of the unrest 1 shown.

In Fig. 1A, the agitation 1 is still of the

Energy transfer means 3 decoupled and is thus still before entering the coupling rotation angle range (falling

Supplement sheet). The energy transmission means 3 abuts against the first stop 24a of the Hemmstücks 7. The inhibitor 7 abuts against the first stopper 2a and inhibits the escape wheel 9 by engaging the first pallet 8a in a tooth 27.3 of the escape wheel 9. In this state of the energy transfer means 3 and / or the Hemmstücks 7, the fork 14 of the energy transfer means 3 in one Position for coupling with the driver 10 of the restlessness 1. The bistable leaf spring 4 is in the high stable energy state, ie has a second order bendline. The leaf spring 4 is stretched to near the instability point. The leaf spring 4 presses in this state, the lever 3 in the first

Direction of rotation against the first stop 24a of the Hemmstücks 7 and thereby the Hemmstück 7 against the first stop 2a. This ensures that the fork 14 is in the coupling rotational angle range in the correct position for coupling with the driver 10 at the onset of restlessness. At the same time, the leaf spring 4 presses in this state, the clamping piece 5 in the second direction of rotation, so that the

Leaf spring 4 presses the second pallet 6b to the corresponding tooth 27.1 of the escape wheel 9.

In Fig. 1 B, the agitation 1 has entered the coupling rotational angle range and the fork 14 is coupled to the driver 10. The energy transmission means 3 is rotated by the force of the restlessness 1 in the second direction of rotation. As a result, the leaf spring 4 is moved out of the local rest position (dashed bend line). The drivers 10 or the unrest 1 forces the buffer 4 against the

Potential barrier.

In Fig. 1C, the agitation 1 is just before the dead center and / or the buffer 4 just before the instability point. The unrest 1 now forces the leaf spring 4 on the potential mountain. at

Overcoming this potential mountain beats the leaf spring 4 of the second-order bending line in the first-order bending line, wherein the thus released energy is released via the energy transfer means 3 to the restlessness 1. This point of instability of the leaf spring 4 is preferably reached at the dead center of restlessness 1. The envelope from the second-order bending line to the first-order bending line is made from the side of the clamping piece 5 in the direction of

Energy transfer means 3. With the turnover changes

Direction of the force transmitted to the lever 3 and the leaf spring 4 now accelerates the unrest 1. While the force direction of the leaf spring 4 on the side of the energy transfer means 3 at

Exceeding the instability point reverses. When the instability point is exceeded, the force direction of the leaf spring 4 changes on the side of the clamping piece 5 and presses the clamping piece 5 now in the first direction of rotation, so that the leaf spring 4, the first pallet 6 a to the

corresponding tooth 27.2 of the escape wheel 9 presses. When the instability point is exceeded, the contact thus changes from the second pallet 6b to the first pallet 6a.

In Fig. 1 D, the buffer 4 is completely transferred. In this case, the energy transmission means 3 first strikes the second stop 24b of the inhibitor 7. At the latest from this point in time, the disturbance 1 is no longer in contact with the energy transmission means 3. The control element can be designed so that in the attack of the

Energy transmission means 3 on the stop 24b the restlessness 1 is already decoupled from the power transmission means 3. As a result, the restlessness 1 is completely independent of possibly caused by the stop disturbances. Alternatively, the control element can be designed so that the restlessness 1 at the exact moment of this attack

decoupled, or directly afterwards, eg by slowing down the Energy transmission means 3 at the stop. If the restlessness 1 at this moment only for the direction of rotation (here the first

Direction of rotation) is coupled to the unrest 1, but not for the

opposite direction of rotation (here the second direction of rotation) is coupled to the disturbance 1, the agitation 1 is not caused by a possibly by the braking of the energy transmission means 3

Return pulse (here in the first direction of rotation of the energy transmission means 3) disturbed. The required for the release of the inhibitor 7 pulse is due to the rotational energy of the energy transfer means. 3

(Inertia) and / or the remaining energy stored in the latch 4 applied. Here, the inhibitor 7 in his

opposite position, i. in abutment with the second stop 2b, brought. With the beginning of the rotation of the Hemmstücks 7 in the second direction of rotation of the escape wheel 9 is released. From the stop of the power transmission means 3 to the stop 24b up to the stop of the Hemmstücks 7 on the stop 2b, the leaf spring 4 exerts a force in the second direction of rotation of the power transmission means 3 on the

Energy transfer 3 from. That's why it stays that way

Energy transfer means 3 in contact with the stop 24b of

Chock 7 and is with the stop of the chafing 7 at the

Stop 2b ready for coupling with the returning rest 1, which then rotates in the opposite second direction of rotation. The release of the escape wheel 9 by the rotation of the Hemmstücks 7 initiates the re-biasing the latch 4 a. By releasing the escape wheel 9, this is driven in the second direction of rotation (also in the first direction of rotation is possible) by the main drive spring. This rotation of the escape wheel 9 causes the escape wheel 9, the tensioning piece 5 rotates against the force of the leaf spring 4 with the first-order bending line in the second direction of rotation. The leaf spring 4 now begins to press the first pallet 6a against the tooth 27.2 of the escapement wheel 9 against the rotation of the tensioning piece caused by the escapement wheel 9. Also this pressure is with further

Rotation of the clamping piece 5 and the escape wheel 9 continuously stronger. With the rotation of the escapement wheel 9, the first pallet 6a slides over the tooth 27.2 of the escapement wheel 9. The escapement 7 located in the stop 2b is arranged so that the second pallet 8b in FIG the next on this range 8b passing tooth 27.4 of

Hemmungsrads 9 engages and the further rotation of the escape wheel 9 beyond the specific rotation angle (braked) is prevented.

In Fig. 1 E, the escape wheel 9 is again in the inhibited state. The tooth 27.4 of the escape wheel 9 is held by the second pallet 8b. In this state, the leaf spring 4 still pushes the first pallet 6a against the tooth 27.2. The buffer 4 is now tensioned in the opposite direction, i. in a bending line symmetrical to FIG. 1A, and again assumes a shape of the second-order bending line. The leaf spring 4 presses the energy transfer means 3 further in the second stop 24 b (and the Hemmstück 7 in the second stop 2 b), so that the fork 14 in the correct position for coupling with the

returning unrest is 1. For very fast-moving riots, the period of the free escapement wheel 9 or the

Charging process of the buffer 4 also extend beyond the moment of the change of direction of unrest 1. It is only important that the escape wheel 9 is inhibited again before the reentry occurs in the coupling rotational angle range and / or the charging process of the buffer 4 (complete) is completed.

Since the leaf spring 4 is again biased into a second-order bending line, the same process can be analogous to the passage of restlessness in the opposite (second) direction of rotation. Only the directions of rotation of all elements rotate (except for the

Escapement wheel 9). The control element is designed so that the expiry of the inhibition with each direction of unrest 1 with

runs the same according to different directions of rotation.

The control organ is characterized by the following

Special features from:

There is no renewed tensioning of the buffer 4 and thus no change in its energetic state during the impulse delivery to the disturbance 1 instead. After completion of the

Impulse transmission to the restlessness 1 unlock the inertia of the Energy transfer agent 3 and the remaining energy in the buffer 4, the escape wheel 9. It is particularly advantageous that no re-tensioning of the buffer 4 during the

Momentum 1 impulses are transmitted as this would nullify the benefits of constant-force inhibition (Force Constant).

The clamping of the buffer 4 takes place during the supplementary arc of the disturbance 1. The energy stored in the buffer 4 is not dependent on the speed of biasing and is therefore not affected by the force of the spring mechanism - as long as the tensioning takes place during the free oscillation arc of the disturbance 1. As a result, the inhibition is insensitive to the influence of lubricants in the drive train, since the viscosity does not affect the pulse. Moreover, this separation also allows slowly oscillating control organs, e.g. to use the agitation 1 without this having any influence on the impulse transmission.

During the supplementary arc of agitation 1, the energy transmission means 3 secures the inhibitor 7. No components of the control organ have an undefined position, whereby they can not generate any unforeseeable disturbances. Additional safety can be provided by a pull angle of the resting pallets 8a and 8b. However, this leads to an influence of the tripping resistance of the Hemmstücks 7 by the power of the drive train.

The pulse angle (angle covered by the energy transfer means 3) is determined mainly by the excess length of the buffer 4. It results from the natural bending line of the second

Order, but can be limited by the stop pins 2a and 2b and / or the systems 24a and 24b. The clamping angle of the clamping piece 5 is determined by the clamping pallets 6 a and 6 b and must also match the second-order bending line of the buffer 4. Therefore, the length of the buffer 4 should first be adapted to the pulse angle of the energy transmission means 3. The clamping angle of the clamping piece 5 is then correspondingly by the clamping pallets 6a and 6b set. Alternatively, the properties of the leaf spring may be varied along the longitudinal axis of the spring (see below), allowing greater freedom between the pulse angle of the energy transferring means 3 and the clamping angle of the clamping piece 5. This can influence the center of gravity of the energy transfer.

Owing to the minimal mass inertia of the energy transfer medium, the coupling rotational angle range can be significantly reduced in comparison with other inhibitions, as a result of which

Energy transfer more the character of a pulse and the time of disturbing influences (for example, vibrations) is significantly shortened, which leads to an improvement in the control performance.

Fig. 3 shows a second embodiment of the control element whose design is not described otherwise unless in the first

Embodiment is formed. The leaf spring 4 'is fixed here instead of on the clamping piece 5' directly to an attachment point 20 on the board and the coupling with the clamping piece 5 'with

Coupling means 19 of the clamping piece 5 'between the attachment point 20 and the axis of rotation 1 1 is realized. This can be a longer

Leaf spring 4 'and / or a smaller escapement wheel 9 (e.g., for the optional installation of Swiss Anchor and Force Constant) may be used. The attachment of the buffer 4 on the board can u.U. be advantageous, e.g. when using an eccentric for fine adjustment. A longer spring 4 'has the advantage that it is less sensitive to changes in length. Preferably, the coupling point of the spring 4 'with the clamping piece 5' is selected so that it is between the point of curvature of the leaf spring 4 'and the

Attachment point 20 is located, ideally on the belly of the second bending line. In this embodiment, the clamping piece 5 'as the clamping piece 5 is formed, in addition, a lever 34 in the direction of

Leaf spring axis is arranged. The lever 34 extends from the

Fulcrum 1 1, starting on the other side of the pivot point 18 of the clamping piece 5 '. On this lever 34, the coupling means 19 are arranged. The coupling point on the lever 34 and on the

Leaf spring 4 'should be designed so that of the Coupling point of the leaf spring 4 'from the first-order bending line to the second-order bending line at least equal to the distance traveled by the coupling means 19 mounted thereon. The coupling point between the clamping piece 5 'and the leaf spring 4' is preferably arranged in the region of the maximum bulge of the leaf spring 4 '. In this system, the coupling point of the

Pivoting point 1 1 arranged on the other side of the pivot point 18 of the clamping piece 5 ', so that the directions of rotation and the pallets 6a and 6b in comparison to those in Fig. 1 to 2 exchange.

Fig. 4 shows a third embodiment of the control element whose design is not described otherwise unless in the first

Embodiment is formed. In this embodiment, the energy transfer means 3 is integrated in a Hemmstück 28. Alternatively, the inhibitor 7 and the energy transfer means 3 could also be connected to each other in a rotationally fixed manner. The inhibitor 28 has the functions of the power transmission means 3 and the inhibitor 7 of the first embodiment. Unlike the first one

Embodiment moves the unrest 1 im

Coupling rotation angle range not only the energy transmission means 3, but the entire Hemmstück 28, as in a classic

Escapement. Unlike a conventional anchor escapement but the inhibitor 28, as previously the energy transmission means 3, connected to the leaf spring 4 and formed so that the escapement wheel 29 is released only from or after the uncoupling of restlessness 1 of the inhibitor 28. This can be achieved, for example, by forming a first pallet 31a connected to a tooth 30.3 of the escapement wheel 29 in such a way that it shifts frictionally along the tooth 30.3 during rotation of the escapement piece 28 during the coupling rotation angle range. Only from or after the decoupling of the driver 1 from the fork 14, the inhibitor piece 28 rotates by the inertia and / or by the remaining energy of the leaf spring 4 and gives that

Escapement 29 and its tooth 30.3 finally free. In this case, the inhibition during the pulse has a frictional rest. This arrangement represents a significant simplification. Nevertheless, here the impulse to the restlessness 1 completely from the charging of the Leaf spring 4 are separated. However, the impulse to the restlessness 1 is additionally influenced by the frictional effects between the escape wheel 29 and the inhibitor 28 compared to the first embodiment. To reduce the friction and / or to facilitate the escape wheel 28, the escape wheel 28 may be formed in a shape similar to a chronometer escapement or a pointed tooth espagnolette with pointed teeth 30 such that only their tips are in frictional contact with the teeth first palette 31 a come. Analogously, there are as in the first embodiment

described a second palette 31 b for re-inhibiting the

Hemmungsrads 29 on the tooth 30.4. While in the first and second embodiments, the inhibitor 7, the escape wheel 9 and the clamping piece 5 in the first plane and the energy transfer means 3, the driver 10 and the buffer 4 are arranged in a second plane, here is the inhibitor 28 in the second Level of the buffer 4 'is arranged, but the pallets 8a and 8b protrude into the second level. Alternatively, one could also do that

Leave inhibitor 28 in the first plane and leave the attachment or coupling means for the leaf spring 4 'protrude into the second plane and / or arrange the driver 10 in the first plane.

Fig. 5 and 6 show a fourth embodiment whose design is not described otherwise unless in the second

Embodiment is formed. The leaf spring 4 "is now attached directly to the board at the second attachment point 35 instead of on the lever 3 '(or on the check piece 28)

Coupling means 21 on the lever 3 'for coupling the leaf spring 4 "with the lever 3' arranged .Thus can the leaf spring 4" continue to extend. For coupling is preferably a lever 37 on the

Energy transfer means 3 'arranged in the direction of

Clamping piece 5 extends and / or preferably in the region of the extreme bulge of the leaf spring 4 "has the coupling means 21. In the embodiment shown, the leaf spring 4" is now on the visible side of the movement, ie on the side facing the dial and facing away from the board of the escape wheel 9 arranged in a third plane. The first level is between the second and third levels arranged, preferably all three planes parallel to the

Dial and / or are arranged to the board. For coupling the clamping piece 5 "with the leaf spring 4", the coupling means 19 'now extends not in the second plane, but in the opposite direction of the third plane. The energy transferring means 3 'is formed in the second plane like the lever 3 (without attachment of the leaf spring 4 ") .The energy transferring means 3' is further supported on the axis of rotation 1 1, eg a journal, on the same axis of rotation but in the third Level, now is the lever 37. The lever 37 of the third level is rotatable or integral with the part of

Energy transmission means 3 'arranged in the first plane.

The length of the buffer 4 is particularly critical. At a given clamping angle, the length of the spring 4 determines its instability line. Too short a buffer 4 will not have sufficient security against shocks or reach a stable position after clamping, both leads to an unplanned release of the stored energy. Too long a cache carries the risk of inefficient energetic use, which equates to unnecessarily high inertia. In the second and fourth

Therefore, it is advantageous that the length of the

Leaf spring 4 'and 4 "can be selected independently of the size of the escapement wheel.The longer the spring 4, the more length error is bearable.

A problem that occurs with all control devices that use bistable leaf springs to drive the rest of constant force is the change in length and / or modulus of the leaf spring with temperature and the difficulty of adjusting the behavior of the leaf spring. The latter depends on the angle of rotation of the energy transmission means 3 / inhibitor 28, the angle of rotation of the clamping piece 5 and the length of the leaf spring 4 or its length ratio to the bearing points. The former leads to a change in the behavior of the leaf spring 4, which in the worst case can lead to a malfunction of the escapement.

In addition, a change in length leads to a change in the energy stored in the buffer 4. A possible solution to the first problem could be to compensate for the thermal length and / or modulus of elasticity of the bistable leaf spring 4 by a thermal change in length of the bearing points of the leaf spring 4 in the board, that of the

Leaf spring 4 delivered to the disturbance 1 pulse constant with the

Temperature is. This can be achieved by choosing suitable materials or appropriate compensation mechanisms.

If one or both bearing points of the leaf spring 4 are not arranged directly on the board as in FIGS. 1 to 5, the bearing point or points in the board of the part on which the leaf spring 4 is mounted are meant. In this case, in addition, the thermal change in length of this part could also be taken into account. In Fig. 1 to 5, for example, the pivot point 1 1 of the bearing point of

Leaf spring 4 on the board and in Figs. 1 and 5, the axis of rotation 18 is the bearing point of the leaf spring 4. In one embodiment, the spring 4 could be e.g. made of bronze and the material of the board between the

Bearing points be made of brass. In another

Embodiment could be the spring 4 and the material of the board between the bearing points of silicon. The same material is very well suited to achieve the same length changes of the spring 4 and the bearing points with temperature changes. However, the spring 4 could also be changed by coatings, treatments and / or oxidations so that the change of the

Modulus of elasticity over the temperature can be compensated by the change in length of the board. In another embodiment, the spring 4 and the material between the bearing points could be made of glass. The material of the board between the bearing points can be either the general board material. Alternatively, another material could be stored in the board, in which the two bearing points of the leaf spring 4 are mounted. If this material of the board longitudinally movably arranged along the leaf spring axis expandable in a second board material, thus a compensation of the length expansion of the spring can be achieved by the temperature, without producing the whole board of this material. There are no special requirements for the materials, although it is recommended for the spring to choose a material with a largely independent of the temperature modulus.

By varying a parameter of the leaf spring 4 over its longitudinal axis can be changed during the pulse from the spring to the energy transfer means 3, transmitted torque curve. As a longitudinal axis of the bending line of the leaf spring 4 following axis should be defined (in contrast to the leaf spring axis). The length is defined by the longest direction of expansion. The parameter influences the local stiffness of the leaf spring 4 along the

Longitudinal axis. For example, a parameter could affect thickness, width, cross-section, and / or modulus of elasticity

Material properties of the leaf spring 4 be. The thickness and the width are preferably arranged at right angles to the longitudinal axis. Preferably, the thickness as the extension of the leaf spring 4 is perpendicular to the longitudinal axis and perpendicular to the pulse output to the

Energy transfer means 3 defined. Preferably, the width (possibly on average over the longitudinal axis) in its extent greater than the thickness.

This can be the integral center of the pulse

(Focus of energy transfer), which eliminates or minimizes gait errors caused by the pulse. The centroid or integral center of the impulse or energy transfer is defined as the angle of perturbation or coupling rotational angle range in which the maximum impulse is transmitted to the perturbation by a power transmitting element (e.g., Swiss Anchor or a latch). In riots receiving energy or impulses in each direction of rotation, there may be two such centroids of the pulse, one for each direction of rotation. Conventional inhibitions with two pulses per balance vibration give symmetrical impulses to the rest position only neglecting the mass inertias. Once inertial forces, such as e.g. in

Wrist watches the case occurs, the center of gravity of the impulse shifts towards late, resulting in a slowing of the gait. A real isochronism is no longer present. By the Buffer having only minimal inertial forces and whose integral center of impulse output can be adjusted to the restlessness by the design of the buffer, the integral center of the impulse can be adjusted to the rest position of restlessness (for both directions of rotation).

If a leaf spring 4 is used with a variable parameter over its longitudinal axis, the instability position of the

Caching 4 are moved. This can u.a. of the

Tripping pulse can be set. This further allows the pulse angle of the energy transmission means 3 and the clamping angle to select the clamping piece 5 independently of each other. The latter can be achieved, for example, by a decreasing cross-section, a decreasing thickness and / or a decreasing width of the clamping piece 5 to the

Energy transfer means 3 can be achieved. The leaf spring 4 could e.g. be formed conically to the energy transfer means 3 out.

Additionally or alternatively, it would be possible that the material properties of the leaf spring 4 are changed from the clamping piece 5 to the power transmission means 3 so that the leaf spring 4 is harder towards the clamping piece 5 out. In a further embodiment, the cross-section, the thickness, the width and / or the local stiffness of the leaf spring 4 in the region of the energy decrease, e.g. 17 or 21, be smaller than in other areas. In a further embodiment, the cross-section, the thickness, the width and / or the local stiffness of the leaf spring 4 in the region of the nodes may be greater than in the areas of greatest curvature, i. the bellies.
