Definitions

  • the present invention relates to a timepiece of the split-seconds chronograph type, equipped with a device for controlling the stopping and starting of a split-seconds hand.
  • a mechanical or electromechanical chronograph comprising a clockwork movement which controls display organs such as a second hand called a "hand" chronograph ", a minute counter and an hour counter. Thanks to this chronograph, we can then determine the time it took for this runner to complete a given route.
  • a chronograph in its simplest version for example a chronograph provided with a single pusher, does not make it possible to measure several successive times, since it necessarily requires a reset of its display members after each measurement. We therefore have recourse in this case to the use of a chronograph provided with an additional seconds hand called "split-seconds hand".
  • FIGs 1 and 2 attached illustrate a chronograph equipped with a device for controlling a split-second hand according to the aforementioned book by B. Humbert.
  • the dial side of the chronograph is located at the top.
  • the split-seconds chronograph is provided with a medium-sized wheel 1 forming part of a mobile 3 pierced over its entire length, a chronograph wheel 5 whose tube 7 pivots inside the mobile 3 and a split-second wheel 9 whose axis 11 is freely adjusted inside the tube 7.
  • a catch-up needle 13 On the free end of the axis 11 is fixed a catch-up needle 13 while the other end of said axis is in abutment against a stone 14 provided in a bridge 16.
  • a chronograph needle 15 is fixed at one end of the tube 7.
  • a heart 17, called split-heart At the other end of this tube is fixed a heart 17, called split-heart which is integral in rotation with the chronograph wheel 5.
  • a chronograph heart 19 is fixed on the tube 7 against the side chronograph wheel 5.
  • the various chronograph parts are arranged on either side of a chronograph plate 21 and a bridge 23.
  • a lever 25 is pivotally mounted under a serge 27 (FIG. 1) of the split-second wheel 9 and pivots about an axis 29. At the free end of this lever 25 is rotatably mounted a roller 31, preferably in ruby . This lever 25 is biased by a spring 33 which is also mounted on the rim 27. Thanks to this spring 33, the roller 31 is kept in permanent contact with the periphery of the split-back core 17.
  • the split-second wheel 9 is arranged between the two branches 35 and 37 of a split-grip pliers 39 in a U so that the ends of these two branches can pinch the wheel 9 in two diametrically opposite places.
  • a column wheel 41 is disposed between the two branches 35, 37 at the height of their middle region.
  • the column wheel 41 present in its upper part (with respect to FIG. 1), that is to say in its part directed towards the bottom of the chronograph case, a cam 42 comprising eight columns 43 regularly distributed around its periphery and in its lower part a ratchet 44 provided with sixteen teeth 45.
  • This column wheel 41 can be rotated in the direction of arrow F1 by a pawl 47 which acts on the teeth 45.
  • This pawl 47 can itself be actuated by a rocker 49 while being subjected to the action of 'a spring 51.
  • the column wheel 41 is locked in rotation by a jumper 53 and the split-second clamp 39 pivots freely around a tenon 55 mounted on an extension of the foot of the jumper 53.
  • the two branches 35 and 37 of the split-second clamp 39 are provided with spouts, respectively 57 and 59 cooperating with the columns 43.
  • the two branches 35 and 37 can move between two positions.
  • a first position shown in Figure 1 the spouts 57 and 59 are respectively between two neighboring columns 43, so that the branches 35 and 37 pinch the split-wheel 9 and lock it.
  • a second position the spouts 57, 59 are respectively in abutment against two diametrically opposite columns 43, which means that the branches 35 and 37 are separated from the wheel 9. The transition from the first position of the branches to the second therefore takes place in the direction of the arrows F2.
  • the roller 31 located at the end of the lever 25 is housed in the notch 61 of the split-second heart 17. Consequently, when the chronograph wheel 5 rotates by advancing in steps, driven by a driving wheel not shown, it drives not only the tube 7, the split-heart 17 and the chronograph hand 15, but also the split-wheel 9 by means of the lever 25.
  • the split-wheel 9 rotates in synchronism with the chronograph wheel 5 and the two hands 13 and 15 rotate simultaneously and are superposed on each other.
  • the user After having read the intermediate time, the user exerts a second pressure on the lever 49. This has the effect of rotating the column wheel 41 by an additional step and of spreading the arms 35 and 37 of the clamp 39.
  • the split-second wheel 9 is released and rotates until the roller 31 of the lever 25 is again in the notch 61 under the action of the spring 33 which was bandaged during the rotation of the split-wheel.
  • the two needles 13 and 15 then start to rotate again.
  • the precaution taken by the watchmaker-manufacturer consists in providing spans between the mobiles only at one end of them (that is to say generally near the hands) as shown in the figure. 2.
  • the opposite end of the mobile is then supported only on an axial stop (stone 14, Figure 2) without being held radially.
  • the mobiles in question can thus adjust themselves radially one inside the other without resulting in premature wear or even blocking in rotation.
  • Document CH 38 824 has drawbacks of the same nature and others in addition since what serves as a split-second clamp is formed by two independent branches fixed by screws.
  • the invention aims to remedy the aforementioned drawbacks.
  • the subject of the invention is therefore a timepiece of the split-seconds chronograph type, equipped with a device for controlling the stopping and running of a split-seconds hand, the piece comprising a split-seconds mobile fixed to said split-second needle, one-piece split-second pliers substantially taking the shape of a U with two branches, two respective ends of which are connected by a connecting portion, the split-second mobile being disposed between the free ends of the two branches, and means for deforming said clamp so that it can assume two configurations, namely a first configuration called closed, in which each branch of the clamp exerts a radial force on the periphery of the split-second mobile so as to block the latter, and a second configuration, called open, in which the two arms of the clamp are not in contact with the split-second mobile so as to leave the latter free and to authorize the running of said split-second needle, this part being characterized in that it further comprises two organs of fixed reactions against which a first side of said connection portion is pressed and in that said deformation means comprise means
  • control device is capable of simultaneously spreading the branches of the split-second mobile and also bringing them together simultaneously, which avoids any asymmetrical radial force on the split-second mobile to a much lesser extent than in the device according to CH-A-38 824.
  • the means for generating a deformation force on the connecting portion have a joint action on the two branches of the clamp, this action being simultaneous on the two branches because it results from the sole application of the deformation force on a same element constituted by the connecting portion.
  • the deformation force is advantageously applied in the middle of the portion of link between the two reaction bodies.
  • the result remains similar throughout a central region centered on the middle of this connecting portion, this central region being greater than the usual tolerances, for a mechanical watch movement, in the positioning of an element such as a column wheel, a ratchet, operating lever, etc.
  • the control device comprises a clamp split-second 101 intended to cooperate with the wheel 102 of the split-second mobile 103 of a chronograph.
  • This mobile 103 is provided with a pivot 105 at the end of which is a catch-up needle 107 (shown only in FIG. 7).
  • the split-second pliers 101 made in one piece has the general shape of a U with two branches 109 and 111 connected by a strip 113 forming a connecting portion.
  • the wheel 102 of the split-second mobile 103 is disposed between the free ends of the branches 109 and 111.
  • the control device is mounted on a plate 114 in which are driven two pins 115 and 117 acting as reaction members.
  • the clamp 101 has in its connection zones between the branches 109 and 111 and the connection portion or lamella 113, arcuate connection portions 119 and 121 which pass around the respective pins 115 and 117 at an angle of approximately 270 °, thus giving the gripper 101 a good seat.
  • Each branch 109, 111 further comprises, going in the direction of its free end, a bent portion 123 bringing it towards the other branch, a straight portion 125 in which a recess 127 is provided, an enlarged portion 129a, 129b and a arcuate portion 131 extending towards the outside of the clamp followed by an active rectilinear portion 133 which tangents the periphery of the wheel 102.
  • each branch located on either side of the recess 127 extend in different planes, those located on the side of the mobile 103 being the furthest from the plate.
  • each branch has a width l 1 greater than the width l 2 of the connecting portion 113.
  • the branches 109 and 111 have in the plane of the clamp a stiffness markedly greater than this connecting portion 113 in which the deformation of the clamp is concentrated, when the latter is urged to release the mobile 103.
  • the control device also comprises deformation means 135, the construction of which is as follows.
  • a pin 137 is driven into the plate 114 and held at its other end by a bridge 114 '.
  • a mobile 141 with two stages 141a and 141b.
  • the first stage 141a located closest to the plate 114 carries a cam 142, with five spans for example, while the second stage forms a ratchet 141b here having ten triangular teeth.
  • the cam 142 is provided in the plane of the clamp 101.
  • the control device also includes a thrust and positioning member 143 formed by a V-shaped spring (FIG. 3A) the tip of which is mounted so as to be able to pivot around a pin 145 driven into the plate 114.
  • a thrust and positioning member 143 formed by a V-shaped spring (FIG. 3A) the tip of which is mounted so as to be able to pivot around a pin 145 driven into the plate 114.
  • a first branch 143a of this V-shaped spring extends from the pin 145 to a gap formed between the cam 142 and the deformable strip 113 of the clamp 101.
  • the free end of this branch is shaped so as to constitute a movement transmission head 143c which is in elastic contact with the profile of the cam 142 while also being in elastic contact with the deformable strip 113.
  • the opposite branch 143b of the pushing and positioning member 143 jumper-shaped to block the mobile 141 and the cam 142 in rotation, when the control device is active (FIG. 3). Otherwise, it is the other branch 143a of the member 143 which ensures the rotation blocking of the mobile 141.
  • the control device also comprises a control lever 147 (FIG. 3B), formed by a curved blade fixed by a first end portion 147a to the pin 145 and to another pin 149 situated at a certain distance from the latter and also driven into the plate 114.
  • a control lever 147 (FIG. 3B), formed by a curved blade fixed by a first end portion 147a to the pin 145 and to another pin 149 situated at a certain distance from the latter and also driven into the plate 114.
  • a narrow portion 147b elastically deformable extends from the pin 149 in the direction of the mobile 141 where it is extended by a wider and more rigid pallet 147c extending approximately at right angles in the same plane as the narrow portion 147b.
  • a tab 147d bent out of the plane of the control lever is intended to cooperate with a push button (not shown) located at the outside of the chronograph case (see in particular Figure 5).
  • the pallet 147c is connected to an actuating portion 147e in the form of a V, the free branch 147f of which has a hook-shaped head 147g intended to act on the ratchet 141b.
  • a buttonhole 147h is pierced in the pallet 147c where the latter is engaged on the pin 115 which thus ensures the guiding of the control lever 147 and prevents deformation outside the plane of the lever, when the latter is actuated.
  • V-shaped portion 147e extends above the rear part of the clamp 101 in order to hold it in place, and to prevent it from moving away from the plate 114 (see in particular the figures 5 and 6).
  • FIG. 7 partially represents a module 151A of a split-seconds chronograph intended to be adapted to a watch movement 151B of the current type, the control device according to the invention being incorporated in the first module 151A.
  • this module 151 A is built on the plate 114 to which the bridges 114 ′ and 139 are fixed. A center tube 153 is driven into the latter.
  • a chronograph heart 165 intended for resetting and conventionally designed is fixed on the mobile 155 above the pinion 159.
  • This mobile is driven by a seconds wheel 167 whose rotation is ensured conventionally from the watch movement 151B, with which the chronograph module 151A is associated.
  • This watch movement 151B is only very partially represented in FIG. 7.
  • the mobile 155 is traversed by an axial passage 169 in which is inserted the axis 105 which is part of the split-second mobile 103 and to which the wheel 102 is fixed as well as a needle 107.
  • the split-second wheel 102 is conventionally constructed (as shown in Figure 1). It is therefore equipped with a split-level lever 171 provided with its roller (not visible in FIG. 7), and with a spring support (also invisible) acting on this lever 171.
  • a split-heart 173 is fixed on the mobile 155 and cooperates with the lever 171 for the execution of the recovery operation.
  • the wheel 102 also cooperates with the clamp 101 forming part of the control device according to the invention.
  • FIG. 7 also shows that the split-second mobile is in axial abutment against a stone 175 embedded in a wheel 177 carried by a second mobile in the center 179 forming part of the watch module 151B to which the chronograph module 151A equipped with its device control according to the invention, is associated.
  • the central seconds mobile 179 pivots in a center tube 181 driven into the plate 183 of the watch module 151B.
  • a roadway mobile 185 provided with its road wheel 187, the arrangement being conventional.
  • the central seconds mobile 179 has, on the side of the chronograph module 151A, a length such that the wheel 177 which it carries can be easily adjusted axially. This possibility of adjustment makes it possible, despite the presence of inevitable manufacturing tolerances, to always adjust the axial support of the split-second mobile 103 at its fair value.
  • the association of any standard watch module with a serial chronograph module constructed as indicated above can then be made without risk of jamming or premature wear of the rotating elements of the center of the assembly.
  • control device The operation of the control device according to the invention is as follows.
  • the clamp 101 does not act on the split-second wheel 102.
  • the split-second mobile 103 and the chronograph mobile 155 are integral in rotation, the hands 107 and 157 being superimposed and moving together.
  • the roller of the lever 171 is located in the notch of the heart 173, there is axial coupling of the two mobiles.
  • the clamp 101 is kept open by the control device, the V-spring 143 of which acts on the deformable strip 113 by exerting a force in the direction of the arrow F4, that is to say perpendicular to the strip 113.
  • the strip is so find in a curved configuration, which spreads the legs 109 and 111 of the clamp which are relatively rigid in the plane thereof.
  • the spring 143 can exert the force F4 on the strip 113 thanks to the fact that its head 143c is in abutment against one of the high areas of the cam 142.
  • the two-stage mobile 141 on which this cam is fixed is kept immobilized in rotation thanks to the opposite branch 143b of the V-shaped spring 143, the end of which acts as a jumper and bears against a low range of the cam 142.
  • the presence of this V-shaped spring 143 is very important. Indeed, this spring makes it possible to transform the rotational movement of the cam 142 into a translational movement of the head 143c, and thus the force F4 is exerted perpendicularly to the strip 113. If this spring 143 was absent and if it was the cam 142 which exerted the force F4, the latter would not be perpendicular to the strip 113, due to the rotational movement of the cam 142.
  • the clamp 101 would risk not opening symmetrically.
  • the control device then passes from the configuration of FIG. 3 to that shown in FIG. 4. Indeed, the progression of one step of the mobile 141 reverses the position of the head 143c and of the jumper of the branch 143b relative to the cam 142, the head 143c descending on a low range thereof, and the branch 143b rising on a high range. Consequently, the cam is again immobilized in rotation, the head 143c acting as a jumper in this case.
  • the strip 113 tends to resume a rectilinear shape thereby bringing the branches 109 and 111 against the chronograph wheel 102.
  • the bringing together of the branches is simultaneous and symmetrical, which avoids any asymmetrical effort on the chronograph mobile 103 capable of tilting it.
  • the branches 109 and 111 of the clamp 101 prevent the mobile 103 from turning, which stops the needle 107 thus allowing the reading of the intermediate time.
  • the chronograph mobile 155 continues to rotate normally to indicate the current time using the hand 157.
  • the user again actuates the control lever 147d which advances the mobile 141 and the cam 142 by an additional step.
  • This spacing is also made symmetrically and simultaneously for the two branches thus avoiding any radial force on the wheel 102 of the chronograph mobile 103.
  • the mobile 103 is rotated by the force exerted by the lever 171 which rotates this wheel 102 until the roller falls back into the notch of the heart 173.
  • the needle 107 then caught up with the needle 157 to turn again in synchronism with it, the needles being rigorously superimposed.
  • each branch 109 and 111 of the clamp 101 is provided with an enlarged portion 129a, 129b, cooperating with a fixed pin 189 placed between the branches 109 and 111 and driven into the plate 114.
  • the portions 129a, 129b may have different lateral dimensions. This is the case in the embodiment shown in Figures 3 and 4.
