    Technical area
    The invention relates to a mechanical movement. It relates in particular to the escapement, in particular the anchor and the escape wheel for such a movement.
    State of the art
    In an anchor escapement of a conventional mechanical clock, as shown in Fig. 1a, an armature 1 interrupts periodically the movement of the escape wheel 2, which represents the last link in the drive chain of each mechanical clock.Each time the movement of the escape wheel 2 is interrupted, the armature moves between the anchor pins 3 of the escape wheel 2. One of the escape wheel pins 3 impinges on the escape wheel 2 on the resting surface of one of the two anchor pallets 4 on the armature 1, whereby the escape wheel 2 is completely stopped. All kinetic energy of the escape wheel and the associated gear train is destroyed. The movement starts again when the armature 1 continues to swing and the escape wheel pin 3 slides on the inclined lifting surface 6 at the end of the anchor pallet 4, which triggers a pulse to the pendulum or the balance. In order to trigger the drive pulse, first the whole wheel train has to be set in motion again. This mechanism is used in principle for all mechanical watches of any size.
    Fig. 1b shows the engagement of the armature with the anchor wheel pin 3 of an escape wheel 2 closer. An escape wheel pin 3 is shown there at the moment of its impact on the resting surface 5 of the anchor pallet 4. Shortly thereafter, the anchor arm with anchor pallet 4 moves to the right and the escape wheel pin 3 slides over the beveled lifting surface 6 of the anchor pallet 4. While the anchor pallet 4 slides over the lifting surface, a pulse is delivered to the armature which drives the pendulum or balance.
    Presentation of the invention
    It is the object of the present invention to provide an armature and an escape wheel for a mechanical movement, by which the impact stress is reduced at the anchor compared to those in mechanical watches of the prior art.
    This object is achieved by an armature and an escape wheel according to claim 1.
    It discloses an armature and escape wheel for a mechanical clock, wherein the armature serves to inhibit the escape wheel and two arms, each with an anchor pallet, which are arranged and movable with respect to the escape wheel so that the two anchor pallets alternately between Ankerradstifte am Engage the escape wheel, come into contact with the escape wheel pins, and move away from the escape wheel pins.According to the invention resilient elements are present for a spring-loaded contact recording and contact delivery between anchor pallets and Ankerradstiften.In addition, according to the invention, the escape wheel on a freewheel.
    The resilient elements cause the conversion and storage of at least a portion of the kinetic energy of the escape wheel in potential energy at the contact between the anchor pallet and a Ankerradstift and stopping the escape wheel.The escape wheel comes to a standstill, but not abruptly like a conventional clock but gently braked. The impulse delivered to the anchor pallet is thus cushioned. As the anchor is moved back away from the escape wheel, the anchor pallet leaves the escape wheel pin by sliding off it. The stored energy in the spring element is returned to the escape wheel pin when leaving the escape wheel pin, whereby the armature receives a pulse and the energy stored in the spring is in turn converted into kinetic energy of the armature.The freewheel on the escape wheel prevents unwanted swinging back of the escape wheel and as such is essential to the function of the escapement according to this invention.
    The resilient elements are arranged in a first embodiment of the anchor while the escape wheel pins are rigid and rigidly secured to the escape wheel.
    In a first variant, for this purpose, the resilient elements are arranged on the armature respectively between an anchor pallet and the associated anchor arm, and the anchor pallet is in each case movably connected to the anchor arm. The escape wheel pins on the escape wheel are rigid.In a specific embodiment, the anchor pallets are each rotatably attached to the anchor. Following the impact of an anchor pallet with an escape wheel pin, the anchor pallet slidably moves along the escape wheel pin, compressing the spring and pivoting the anchor pallet about an axis of rotation at the armature to the anchor arm.When swinging back the anchor, the anchor pallet moves back again by swinging back and the spring relaxes again. The stored energy in the spring is delivered to the anchor wheel pin via the anchor pallet.
    In a second variant of the first embodiment, the resilient elements are arranged on the anchor, wherein they are realized in the anchor pallet itself. The anchor pallet is firmly connected to the anchor arm. In this solution accounts for a separate spring element and the rotatable attachment to the anchor.
    In a second embodiment of the invention, the resilient elements are arranged on the escape wheel pins on the escape wheel while the anchor pallets are rigid and rigidly connected to the armature.In a specific embodiment, the escape wheel pins are resilient, with the escape wheel pins not attached to the perimeter of the escape wheel, but extending radially outwardly from the wheel axle.A storage of the kinetic energy of the escape wheel is achieved in this solution by a spring on the escape wheel itself instead of in a spring at the anchor.
    In a further embodiment of the invention, a combination of these embodiments is possible by resilient element are present both at the escape wheel and at the anchor.
    The resilient elements are realized in specific embodiments in each case by a pressure, tension or torsion spring.
    Other specific embodiments include Ankerradstifte or anchor pallets, which are made of a resilient material.
    In further embodiments of the invention, in combination with the above-disclosed embodiments, the anchor pallets each have a leading to the free end of the anchor pallet chamfered lifting surface.
    The armature and the escape wheel according to the invention provide several advantages in terms of the energy required to drive a mechanical clock. In addition, it provides significant benefits in terms of the life of a movement, by the constant wear of the gear train and the armature is significantly reduced.
    The invention causes a massive reduction of the required drive energy and mechanical stress of all moving components of a clock. With small clocks with low masses, the running time increases, with clocks and especially with monument clocks this technique allows a rigorous reduction of the forces occurring at the anchor, at the escape wheel as well as in the entire gear train. It reduces mechanical shock, wear and friction losses. The required drive energy, be it a weight or an elevator spring, is thereby greatly reduced in size.
    However, the invention can be effectively applied not only in clocks but also in small mechanical watches.
    Brief description of the figures
    [0019]<Tb> FIG. 1a and 1b show in a perspective view and a front view, respectively, an escape wheel and an armature for a mechanical watch, as they are known in principle from the prior art.<Tb> FIG. 2a and 2b show in a front view and perspective view, respectively, a first embodiment of an armature and escape wheel according to the invention with compression springs arranged on the armature and rotatably mounted anchor pallets. The escape wheel is designed with rigid escape wheel pins attached to the perimeter of the escape wheel.<Tb> FIG. 3a and 3b <SEP> show in a perspective view and a front view, respectively, a second embodiment of an armature and escape wheel according to the invention with springy armature pallets. The escape wheel is as shown in Fig. 2a, 2b executed.<Tb> FIG. Fig. 4 shows in a front view a third embodiment of an armature and escape wheel according to the invention with spring-loaded escape wheel pins fixed to the wheel axle and extending radially from the wheel axle.The anchor is designed with rigid anchor pallets. In a variant (not shown) of the embodiment of Fig. 4, the spring-loaded anchor pins extend approximately radially from the wheel axle, but their extension away from the wheel axle deviates somewhat from the radial. They extend at an angle to the radial, for example at an angle greater than 10 °, for example at an angle of 20 ° to the radial. The anchor is again designed with rigid anchor pallets.
    Embodiments of the invention
    It is shown in Fig. 2a and 2b, an armature Aa with an anchor axis 1a. Two anchor arms 1 extend from the axis 1 a at an angle to each other and each have in the region of their free ends an anchor pallet 4 a, which is rotatably mounted on the anchor arm 1 about an axis 7. In the case of both anchor pallets 4 a, a spring 8 is arranged between the anchor pallet 4 a and the free end of the anchor arm 1. The escape wheel 2 is a "conventional" escape wheel as shown in Fig. 1 with anchor pins which are secured to the periphery of the wheel and extending therefrom parallel to the axis of rotation of the escape wheel.The armature A is arranged with respect to the escape wheel 2 so that upon an oscillating movement of the armature, the armature pallets 4 a engage between two escape wheel pins 3. If an anchor arm 1 moves between two escape wheel pins 3, the anchor pin 3 impinges on the resting surface 5 of the anchor pallet 4a, the armature pallet rotates under the pressure of the anchor pin 3 about its axis 7 and the spring 8 is compressed. In this case, part of the kinetic energy of the escape wheel 2 and of the escapement wheel 2 upstream gear train (not shown) is stored by the spring 8 as potential energy. This energy is returned to the armature Aa in the form of kinetic energy when the armature pallet 4a leaves the anchor pin 3 when swinging back. In this case, when the escapement wheel pin 3 slides over the lifting surface 6, an impulse wheel approximately radially acting on the lifting surface 6 is exerted, so that the armature 1 and thus also the pendulum connected to it or the balance connected to it receive a drive impulse.
    A stop 9 limits the path of the rotatable anchor pallet 4a such that the anchor pallet has a well-defined basic position, which leads to equal forces at each clock and thus to reproducible accuracy of the drive.
    The anchor pallet 4a has, for example, at its free end a beveled lifting surface 6. The oblique lifting surface has the sole purpose of converting the tangentially acting driving force of the escape wheel into a radially acting force, which triggers a pulse to the armature. The reduction of wear takes place solely by the resilient impact of the anchor pin.The movable armature pallet 4a may on its the Ankerradstift 3 side facing both a resting surface 5 and at its free end a lifting surface 6, which when sliding the Ankerradstiftes 3, the spring force in a substantially to the escape wheel 2 radially acting acceleration force of the armature 2 and thereby the with the anchor connected pendulum or the balance walks. The anchor pallet 4a may also be configured solely with a lifting surface 6.
    A freewheel on the escape wheel 2 e.g. in the form of a ratchet toothing 22 with free-wheeling pawl 20 rotating about the pivot point 21 prevents the return swing of the escape wheel 2.
    Fig. 3a and 3b show a variant of the invention with resilient elements on an anchor Ab. Instead of about an axis rotating anchor pallets here the anchor pallets 4b are firmly connected to the anchor arms 1. In order to achieve a storage of kinetic energy of the escape wheel 2, the anchor pallets 4b are each made of resilient material. FIGS. 3a, 3b show the resilient anchor pallets 4b at the moment of sliding of the escape wheel pin 3 on the right anchor pallet 4b. Upon impact of an anchor pallet 4b on an escape wheel pin 3, the anchor pallet 4a is pressed down relative to the armature A, deflecting itself. The kinetic energy of the rotating escape wheel 2 and the associated upstream gear train is converted into deformation energy of the designed as a leaf spring anchor pallet 4b.As soon as the anchor pallet 4b slides back along the anchor pin 3, the resilient anchor pallet 4b relaxes and releases its stored energy back to the armature Ab in the form of kinetic energy until it leaves the pin 3 altogether. A freewheel with freewheel pawl 20 and ratchet teeth 22 on the escape wheel 2 also prevents the spring back of the escape wheel.
    Fig. 4 shows the embodiment of the invention with resilient elements on an escape wheel 12 and with a rigid armature Ac. This rightward rotating escape wheel 12 has no circumferential hoop. Instead, according to the invention, it has radial armature teeth or anchor pins 13 which extend radially from the axis of the escape wheel 12, each armature pin 13 being made of a resilient material. The armature Ac is designed with anchor pallets 4c, which are rigid and firmly connected to the armature arms 1.In the interaction of armature Ac with escape wheel 12, an anchor pallet 4c engages between two anchor pins 13. An anchor pin 13 is deflected against the movement direction of the escape wheel 12 upon impact with an anchor pallet. The kinetic energy of the rotating escape wheel 12 is converted into voltage energy of the resilient escape wheel teeth 13. When the armature Ac returns, the anchor pallet 4c slides along the pin 13 and the spring tension decreases again. The armature teeth 13 then pass the energy on to the lifting surfaces 6c of the armature pallets 4c, which triggers the radial pulse to the armature Ac.Also in this embodiment, an unillustrated freewheel prevents the reverse rotation of the escape wheel.
    The free ends of the anchor pallets 4c are here designed with a beveled lifting surface 6c. However, the lifting surfaces 6c in this embodiment are arranged on the one armature pallet on the outer side of the armature facing away from the armature axis 1a. At the other anchor pallet, the lifting surface 6c is arranged on the inner side facing the armature axis 1a.
    The movable anchor pallets 4a or resilient anchor pallets 4b are used analogously in anchors of all types. Figs. 2-4 show a simple shear inhibition.During operation of a clock with armature and escape wheel according to the invention, the kinetic energy of the gear train is in each case converted into spring tension upon impact of the escape wheel pin 3 with the movable armature pallet 4a, 4b, 4c. This spring tension can be cached by means of a compression, tension or torsion spring or the tension in the made of resilient material anchor pallet. The spring stiffness and travel are designed so that the spring can absorb the kinetic energy to the greatest extent possible, which the rotating escape wheel exerts on the anchor pallet via the escape wheel pin.
    Thus, the potential energy of the spring is also forwarded to a pendulum connected to the anchor or connected to the anchor balance and does not lead to a spring back of the escape wheel 2, 12, the escape wheel has a freewheel. This can have all types of freewheel. 2 and 3 show a simple freewheel ratchet teeth 22 with freewheel pawl 20 on the circumference of the escape wheel. 2
    Also possible are freewheels on the axis of the escape wheel, this on all embodiments of the invention and in particular for the embodiment in Fig. 4th These are e.g. Roller freewheels, the delay-free and regardless of the way the escape wheel 12 prevent its reverse rotation.
