Definitions
- Assembly intended to equip a mechanism or a timepiece and comprising at least one elastic element and at least one first and one second timepiece component
- the subject of the present invention is an assembly intended to equip a mechanism or a timepiece and comprising at least one elastic element, in particular a leaf spring, and at least a first and a second timepiece component.
- a watch mechanism there are many watch parts or components that are subjected to the action of an elastic element, such as a spring or a leaf spring.
- an elastic element such as a spring or a leaf spring.
- the elastic element comprises at least one first end fixed rigidly in a first timepiece component, which may be a fixed part (plate, bridge, frame) of the timepiece movement or a mobile component (hammer, lever, etc.).
- the second end of the elastic element can either come to bear (punctually or permanently) against a second timepiece component (fixed or mobile) or can also be rigidly fixed to said second timepiece component.
- a pawl for example, one end of the spring blade is fixed to a fixed part of the movement while the other end comes to rest against the lever.
- the hammer it is possible to fix the two ends of the spring rigidly, one on a fixed part of the movement and the other on the hammer.
- a system is generally used combining two pins or tubes and one or more screws (pin-screw connection). It is also possible to crimp the end of the elastic element in a tenon by sliding said end in a slot of said tenon before deforming the latter to ensure rigid fixing (binding by permanent deformation of a third part).
- the elastic element is made of a hard metal, most often steel.
- Silicon has several advantages for use as an elastic element or spring in a watch movement: high breaking stress, lightness, hardness, manufacturing precision, possibility of producing complex shapes, low friction, chamfer possible.
- silicon also has drawbacks, the main one being its brittle behavior. It is therefore very difficult to screw one end of an elastic silicon element for its rigid assembly on a watch component.
- the brittle behavior of silicon in fact requires the use of an intermediate seal, specific surface conditions and/or controlled tightening torques, all of which are constraints that make assembly or manufacturing complex. A connection of the pin-screw type is therefore difficult to implement.
- the object of the present invention is therefore to propose a solution for the assembly of an elastic element on a watch component which is suitable for fragile materials such as silicon, which ensures a rigid assembly between the elastic element and the timepiece component in the service position of the assembly in a timepiece mechanism and which allows easy assembly and disassembly of the assembly and preferably without tools or deformation of the parts.
- the assembly solution according to the invention also allows adjustment of the position and of the force of the elastic element exerted on the watch components.
- the subject of the present invention is an assembly comprising at least one elastic element and at least one first and one second horological component according to the alternative of claim 1 or of claim 4.
- Figure 1 illustrates a first embodiment of the invention comprising a hammer and its return spring.
- Figure 2 illustrates a variant of the embodiment of Figure 1.
- Figures 3a and 3b illustrate a variant of the first embodiment of the invention allowing adjustment of the force of the elastic element.
- Figures 4a to 4c illustrate a second embodiment of the invention and its variants.
- Figure 5 illustrates a variant of the invention and embodiments of Figures 1 to 4c.
- the first embodiment of the invention illustrated in FIG. 1 comprises a chronograph hammer 1 pivoted at A and subjected to the action of its return spring 2.
- the hammer 1 and return spring 2 assembly is intended to equipping a clockwork mechanism and in particular a chronograph mechanism.
- the hammer 1 comprises an active end 10 intended to cooperate with a chronograph heart of the chronograph mechanism and a beak 12 intended to cooperate with a control member (column wheel for example).
- the return spring 2 for its part comprises a first end 21 intended to cooperate with the hammer 1 and a second end 22 intended to be rigidly connected to a fixed part (bridge or plate for example, not shown) of the chronograph mechanism.
- this second end 22 of return spring 2 is fixed rigidly in said fixed part by means of pins and screws.
- the first end 21 of the return spring 2 it either bears against a portion of the hammer 1, or is also fixed rigidly to the hammer 1 by a pin and screw system.
- the invention proposes another type of rigid connection between the return spring 2, the fixed part of the mechanism and the hammer 1 making it possible to guarantee the rigidity necessary for the operation of the assembly in service in a clockwork mechanism but also the use of fragile material, preferably silicon, oxidized silicon or a ceramic, for the return spring 2.
- the first end 21 of the return spring 2 must be rigidly connected to the the hammer 1 so as to be fixed relative to the hammer 1 at least along the x and y axes, that is to say in the plane of the hammer 1.
- the second end 22 of the spring reminder 2 in the service position, must be rigidly connected to a fixed part of a clockwork mechanism, so as to be fixed with respect to this fixed part at least along the x and y axes.
- the first end 21 of the return spring 2 has a first particular shape shaped to be housed in a counter-form 11 made in the hammer 1.
- the second end 22 of the spring reminder 2 has a second particular shape intended to cooperate with two fixed elements of the fixed part of the chronograph mechanism, represented by first and second stops or pins 31 and 32 in figure 1.
- the return spring 2 in the service position of the assembly in the chronograph mechanism (assembled position of the assembly in the chronograph mechanism and hammer 1 at rest, FIG. 1), the return spring 2 is prestressed , that is to say that it exerts a torque on the hammer 1 and the first and second stops 31, 32.
- This torque is on the one hand arranged to tend to move the hammer 1 so that it strikes the chronograph heart.
- the prestressing torque of the return spring 2 tends to maintain the first end 21 of the return spring 2 in the counter-form 11 of the hammer 1, the contact between these two elements taking place in at least, but preferably exactly, three first distinct point bearing zones 111, 112, 113.
- the prestressing torque tends to keep the second end 22 of the return spring 2 bearing against the first and second stops 31, 32 at least three second separate punctual bearing zones 221, 222, 223, (that is to say at least one second punctual bearing zone 221 on the first stop 31 and at least two second punctual bearing zones 222, 223 on the second stopper 32, as shown, or vice versa).
- the connection between the first end 21 of the return spring 2 and the counter-form 11 of the hammer 1, the connection between the second end 22 of the return spring 2 and the first and second stops 31, 32, and the preloading torque of the return spring 2 form an assembly or rigid mounting of the return spring 2 in the hammer 1 and on the fixed part of the mechanism (represented by the stops 31, 32) in which all the degrees of freedom incompatible with the functioning of the assembly are blocked.
- the return spring 2 in the service position of the assembly in the chronograph mechanism (position which corresponds to the rest position of the hammer in the chronograph mechanism), the return spring 2 therefore exerts an elastic force on the hammer 1, a force which therefore serves on the one hand to return the hammer to the operation of the assembly and also to the rigid assembly of the return spring 2 on the hammer 1.
- the return spring 2 in the service position therefore exerts a constraint on the hammer 1 and on the fixed stops 31,32 arranged to move the hammer relative to said stops to bring it back to its initial position and to guarantee the rigid connection between the return spring 2 and the hammer 1.
- the return spring 2 is preferably made of silicon, oxidized silicon or another fragile material (glass, sapphire, ceramic, etc.). The use of these materials for the return spring 2 is facilitated thanks to the present invention since it is not necessary to screw/drill/pinch/plastically deform the return spring 2 for its assembly on the hammer 1 and/ or the fixed part (represented by the stops 31, 32).
- the arrangement of the parts has the advantage of reduced overall height since the return spring 2 and the hammer 1 are in the same plane.
- FIG. 2 illustrates this variant in which the hammer 1 carries third and fourth stops 33, 34 arranged to cooperate with the first end 21 'of the return spring 2.
- the prestressing torque of the return spring 2 tends to keep the first end 21' of the return spring 2 bearing against the third and fourth stops 33, 34 in at least three first point support zones
- This variant uses the two levels (hammer and return spring) usually found with a hammer/spring assembly assembled by a pin/screw connection. This variant also makes it possible to keep an existing hammer and adapt it to its use with a return spring in a fragile material such as silicon or oxidized silicon.
- the return spring could comprise one end fixed to its corresponding timepiece component (fixed part or hammer) by any suitable means known to those skilled in the art.
- one end of the return spring could be fixed rigidly to the hammer or to a fixed part by means of a pin/screw connection or by permanent deformation of an additional assembly part.
- the other end of the return spring is fixed to the other of the hammer or the fixed part according to the rigid connection by obstacles described above.
- the return spring came in one piece with the hammer or the fixed part, the connection with this component therefore being one-piece, while the other end of the return spring is fixed to the other of the hammer or of the fixed part according to the rigid connection by obstacles described above.
- the third and fourth stops 33, 34 could be carried by the first end 21 'of the return spring 2 while the hammer 1 has a shaped portion to cooperate with each of these stops to form a rigid link by obstacles as described above.
- the assembly according to the invention formed of at least one elastic element intended to cooperate with at least a first and a second of the timepiece components is arranged to make it possible to adjust the position of the elastic element, its winding and therefore the force exerted on said timepiece components.
- This embodiment also facilitates the positioning of the elastic element.
- the elastic element 5 comprises a first end 51 intended to be rigidly connected to a fixed part of a clockwork mechanism in the service position and an elastic arm 53 terminated by a second end 52 intended to cooperating with a second timepiece component, not shown, for setting this second timepiece component in motion.
- the first end 51 is arranged to cooperate with a first stop 6 and a second stop 7 fixed in the clockwork mechanism.
- This first end 51 comprises in particular a shape, here a V-shaped slot, in which the first stop 6 is housed.
- the elastic element 5 and in particular its arm 53 is prestressed, that is to say it exerts a torque on the second component (not shown) via its second end 52 and on the first and second stops 6, 7.
- this torque tends to move the second component relative to the fixed stops 6, 7 for the operation of the assembly.
- this torque tends on the other hand to maintain the first end 51 of the elastic element in contact with the first and second stops 6, 7 and in particular the first abutment 6 in the slot of the first end 51.
- the contact between the first end 51 and the two abutments 6, 7 is made in at least three, preferably exactly three specific support zones: two first zones point support 61, 62 between the slot and the first stop 6 and a third point point support zone 71 between the first end 51 and the second stop 7.
- the connection between the first end 51 of the elastic element 5 and the stops 6, 7 is therefore similar to the connection between the second end 22 of the return spring 2 and the first and second stops 31, 32 of the first embodiment: it is of a rigid link by obstacles in which certain degrees of mobility are suppressed (here, in x and in y), but each degree of mobility is only suppressed once.
- the second stop 7 is an adjustable stop such as for example an eccentric as illustrated in FIGS. 3a and 3b.
- the eccentric 7 By pivoting the eccentric 7, it is possible to adjust the position of the first end 51 and therefore the winding of the elastic element 5 and of its elastic arm 53 and the force exerted by said arm and the second end 52 of the elastic element 5 on the second timepiece component not shown for setting it in motion.
- This arrangement also facilitates the positioning of the elastic element 5, in particular by the presence of a clearance between the first end 51 of the elastic element 5 and the eccentric 7.
- FIGS. 4a to 4c A third embodiment of the invention illustrated in FIGS. 4a to 4c applies to the case where, in the service position of the assembly in a clockwork mechanism, the elastic element does not exert any prestress (sufficient ) on the watch component to which it must be rigidly connected.
- the elastic element 1005 comprises a first end 1051 intended to be rigidly connected to a first watch component (symbolized by the stops 1006, 1007) in the service position of the assembly and an elastic arm 1053 terminated by a second end 1052 intended to cooperate with a second timepiece component (not illustrated) for its displacement during operation of the assembly.
- the first end 1051 is arranged to cooperate with a first abutment 1006 and a second abutment 1007, both integral with the first timepiece component.
- This first end 1051 notably comprises a shape, here a V-shaped slot, in which the first stop 1006 is housed.
- the elastic element 1005 in the service position of the assembly, is not (not at all or not sufficiently) prestressed and does not exert sufficient torque on the stops 1006 and 1007 to maintain the first end 1051 of the elastic element 1005 in contact with the first and second stops 1006, 1007 and in particular the first stop 1006 in the slot of the first end 1051.
- the elastic element 1005 in the service position does not exert sufficient torque on the first component and the stops 1006 and 1007 to form a rigid connection by obstacles similar to the connection between the second end 22 of the spring reminder 2 and the first and second stops 31, 32 of the first embodiment.
- the elastic force necessary to create the rigid connection by obstacle between the elastic element 1005 and the first component (1006, 1007) is exerted by additional elastic means. Provision is therefore made for elastic means 1500 arranged to exert a force or a torque on the elastic element 1005 and its first end 1051. This torque tends to maintain the first end 1051 of the elastic element 1005 in contact with the first and second stops 1006, 1007 and in particular the first stop 1006 in the slot of the first end 1051.
- the contact between the first end 1051 and the two stops 1006, 1007 is made in at least three, preferably exactly three point support zones: two first point support zones 1061, 1062 between the slot and the first abutment 1006 and a third point support zone 1071 between the first end 1051 and the second abutment 1007.
- the connection between the first end 1051 of the element elastic and the stops 1006, 1007 is therefore similar to the connection between the second end 22 of the return spring 2 and the first and second stops 31, 32 of the first embodiment: it is a rigid connection by obstacles in which certain degrees of mobility are removed (here, in x and in y), but each degree of mobility is removed only once.
- FIGS 4a to 4c illustrate three variants of additional elastic means 1500.
- the additional elastic means 1500 comprise a leaf spring 1501 arranged between the first component and the first end 1051 of the elastic element 1005.
- the leaf spring 1501 bears against the first end 1051 of the elastic element 1005 but is not fixed thereto.
- the leaf spring 1501 is chosen and arranged to exert, in the service position of the assembly, a force or a torque on the first end 1051 which tends to maintain said first end 1051 of the elastic element 5 in contact with the first and second stops. 1006, 1007 and in particular the first stop 1006 in the slot of the first end 1051.
- the leaf spring 1501 thus participates in forming a rigid connection by obstacles similar to that described above for the first and second embodiment.
- Figures 4b and 4c illustrate a variant of the additional elastic means 1500 in which these additional elastic means 1500 comprise a leaf spring 1502, 1503 of which at least one end is fixed on the elastic element 1005 (either the leaf spring 1502, 1503 is attached on the elastic element 1005 or the leaf spring 1502, 1503 came in one piece with the elastic element 1005).
- the other end of the leaf spring 1502, 1503 bears against a third stop 1504 carried by a fixed part of the movement or by the first component.
- the leaf spring 1502, 1503 is chosen and arranged between the third stop 1504 and the elastic element 1005 to exert, in the service position of the assembly, a force or a torque on the first end 1051 which tends to maintain said first end 1051 of the elastic element 1005 in contact with the first and second stops 1006, 1007 and in particular the first stop 1006 in the slot of the first end 1051.
- the leaf spring 1502, 1503 thus participates in forming a rigid connection by obstacles similar to that described more high for the first embodiment.
- the variants of FIGS. 4b and 4c diverge on the shape of the leaf spring (straight for leaf spring 1503 and curved for leaf spring 1502).
- this variant illustrates the case where the elastic means 1500 are arranged between the first component and the elastic element of the assembly according to the invention.
- the elastic means 1500 could rest on a fixed part of the movement distinct from the first component of the assembly according to the invention.
- the second stop 1007 and/or the fulcrum 1504 of the elastic means 1500 could be adjustable stops as in the second embodiment described in FIGS. 3a and 3b.
- the connections between the first end of the elastic element and the watch component or components are arranged to eliminate the degrees of mobility of the elastic element in x and y .
- the elastic element remains free along the z axis, a degree of mobility which it is not always necessary to limit in order to ensure the proper functioning of the elastic element.
- one solution to limit the degree of mobility in z is to choose the elastic element and/or the elastic means so that the torque generated exerts sufficient friction on the component to limit movements along the z axis.
- FIG. 5 Another solution is illustrated in FIG. 5 in which the elastic element is also retained along the z direction.
- the elastic element 5 still comprises a first end 51 intended to be rigidly connected to a first timepiece component 100 in the service position of the assembly and an elastic arm 53 terminated by a second end 52 intended to cooperate with a second watch component not illustrated for setting it in motion.
- the first end 51 is arranged to cooperate with a first abutment 8 and a second abutment 9 fixed in the first timepiece component 100 which can be a fixed part of a timepiece mechanism.
- This first end 51 comprises in particular a shape (not visible in figure 5) in which the first stop 8 is housed.
- the elastic element 5 and in particular the elastic arm 53 is prestressed, that is to say that said elastic arm 53 exerts a torque on the second component (not shown) via its second end 52 and on the first and second stops 8, 9.
- This torque tends on the one hand to move the second component relative to the fixed part for the operation of the assembly and on the other hand, this torque tends to maintain the first end 51 of the elastic element in contact with the first and second stops 8 , 9 and in particular the first abutment 8 in the slot of the first end 51.
- the contact between the first end 51 and the two abutments 8, 9 is made in at least three, preferably exactly three point support zones: two first punctual support zones between the slot and the first abutment 8 and a third point bearing zone between the first end 51 and the second abutment 9.
- elastic means such as those described with reference to the third embodiment could be provided to maintain the first end 51 of the elastic element 5 in contact with the first and second stops 8, 9 and the connection by obstacles between the elastic element 5 and the first component 100 in the service position.
- the first and second stops 8, 9 comprise a head 81, 91 covering a stud 82, 92.
- the supports of the first end 51 of the elastic element are made on the studs 82, 92.
- the head 81, 91 of each abutment 8, 9 is arranged to cover a portion of the first end 51 of the elastic element 5 in the service position of the assembly in order to retain said element in the z direction.
- the subject of the present invention is an assembly intended to equip a timepiece mechanism and comprising at least one elastic element and at least one first and one second timepiece component.
- the elastic element is intended to cooperate with each of the two horological components for setting movement of one of the components relative to the other during the operation of the assembly.
- the elastic element comprises a first end intended to cooperate with the first timepiece component and a second end intended to cooperate with the second timepiece component.
- the elastic element in the service position of the assembly in the clockwork mechanism, is arranged to exert a prestressing torque on the first and second clockwork components, a torque which tends to move the one of the watch components with respect to the other (for example, return spring).
- the elastic element and its first end are shaped so that, in the service position of the assembly, said prestressing torque exerted by the elastic element on the first component and the second component maintains the first end of the elastic element in abutment on the first component in at least three first point support zones arranged to eliminate at least two degrees of freedom of movement between the first end of the elastic element and the first component.
- connection thus formed between the elastic element and the first component in the service position of the assembly is isostatic.
- the elastic element, the second component and the second end of the elastic element are shaped so that, in the service position of the assembly, the torque exerted by the elastic element on the first component and the second component maintains the second end of the elastic element in abutment on the second component in at least three second point support zones arranged to eliminate at least two degrees of freedom of movement between the second end and the second component.
- connection thus formed between the elastic element and the second component in the service position of the assembly is isostatic.
- the assembly further comprises elastic means separate from the elastic element (in the sense that the forces elastics produced by one and the other are distinct and/or are not exerted on the same objects) and arranged to cooperate with the elastic element to maintain the first end of the elastic element in abutment on the first component in at least three first point support zones arranged to eliminate at least two degrees of freedom of movement between the first end of the elastic element and the first component.
- the elastic means are either attached to or come in one piece with the elastic element.
- the second end of the elastic element is rigidly fixed to the second component by means of two screws and a pin, by being crimped in a tenon, by means of a ball joint or by being glued, brazed or made in one piece with said second end (traditional connections).
- the first component and/or the second component are mobile or fixed components.
- the first component is a movable component and the second component is a fixed component.
- the present invention thus allows the assembly of an elastic element on a watch component which is suitable for all materials and in particular for fragile materials such as silicon, oxidized silicon, glass, sapphire or ceramics, which ensures an assembly rigid between the elastic element and the watch component in the service position.
- the assembly according to the invention allows easy assembly, without tools, and also disassembly of the assembly, again without tools and without plastic deformation of parts.
- the present invention provides alternatives applicable to cases where the elastic element exerts sufficient torque on the watch component in the service position of the assembly and to cases where the elastic element does not (not at all or not always) exert sufficient torque on the component watchmaker in service position of the assembly.
- These alternatives apply the same principle of rigid connection by obstacles simply adapted to the arrangement of the elastic element with respect to the components with which it cooperates.
- the construction requirements for the elastic element or the additional elastic means according to the alternatives are not exaggerated since the torque exerted for maintaining the connection by obstacles does not need to be excessive and the stressing can remain soft .
