Definitions

  • the present invention relates to a locking device for timepiece, this device comprising a first rotating mobile around an axis, this first mobile being capable of immobilizing a second movable in first and second positions defined respectively by first and second stops against which said second rests mobile.
  • FIG. 1 represents this prior art.
  • This figure shows an escape wheel 22, center 30 and provided with teeth 31, this wheel cooperating with an anchor 3.
  • This wheel is riveted on the last pinion of the gear train, which cog is driven by a spring barrel.
  • the shape of the teeth 31 is such that the impulse plane is partially on the tooth and on the anchor to form a shared impulse or Swiss anchor escapement.
  • Anchor 3 is driven on a rod which pivots in 12.
  • the anchor is formed by two arms notches in which an input pallet 16 and a exit pallet 17.
  • the anchor 3 also includes a fork 18 which cooperates with a pin 19 mounted on a large plate 20.
  • the fork still includes two horns 32 and 33.
  • the large plate integral with a pendulum (not shown), pivots around an axis 2.
  • the rod of the anchor 3 has its stroke limited by two stops or pins 4 and 5.
  • the anchor 3 At rest, that is to say while the large plate 20 traverses its additional bow, the anchor 3 is positioned against one or the other of the limitation stops 4 and 5. During this time, it may happen that a shock moves the anchor from its initial position of support against one or other of the limitation stops. This tilting tends to bring the anchor prematurely against the other limitation stop. In such a case and when a sting - which will be described below - is missing, the pin 19 of the large plate 20, when the end of its additional descending arc, will no longer meet the entrance but the reverse of one of the two horns 32 and 33. This will immediately stop the pendulum and timepiece. This defect is called overturning. It is, as we recall, the moment when the peg 19 of the large plate 20 accidentally meets the reverse of horn 32 or 33, in place of the entry of the fork 18.
  • the end of the rod is fitted anchor of a dart 34 which makes it possible to avoid overturning by coming to rest against the periphery 35 of a small plate 1 mounted coaxially to the large plateau 30. This support takes place during the additional arc.
  • the small tray 1 is provided with a notch 36 which lets the dart 34 pass when the anchor rod passes from the stop 4 to the stop 5 and vice versa.
  • the sting 35 and the small plate 1 constitute an example of locking device that can be encountered in a timepiece since, when the large plate traverses its additional arc, the anchor is locked and cannot be moved to another position.
  • This device therefore includes a first mobile 1 rotating around a axis 2, this first mobile being capable of immobilizing a second mobile 3 in first and second positions defined respectively by first 4 and second 5 stops against which said second rests mobile 3.
  • the aim of the present invention is to propose a new form of locking device which can be applied both to the exhaust which just described that other forms of escape or mechanisms used in watchmaking.
  • the excursion angle of the anchor rod is of the order of 15 ° which allows the locking device known to work well, the sting 34 being able engage safely and with enough clearance in the notch 36 of the small plate 1.
  • the angular excursion of the anchor is much smaller, of the order of only 5 °, so that the proper functioning of the conventional locking device is no longer insured, as the dart risks touching the small child's notch plateau and brace against it then causing the stopping of the exhaust.
  • the locking device of the present invention is remarkable in that the first mobile is a circular plate surrounded by a skirt having internal and external walls, said skirt having a cut arranged to be crossed by a finger fixed on the second mobile, this second mobile being immobilized in the first position when it is in contact with the first stop and its finger adjoins the inner wall of the skirt, and in the second position when it rests on the second stop and his finger adjoins the outer wall of said skirt.
  • the device of locking comprises a first mobile 1 rotating around an axis 2, and a second mobile 3.
  • This second mobile 3 is capable of being immobilized by the first mobile 1 in first and second defined positions respectively by the support of the second mobile 3 on the first and second stops 4 and 5.
  • the Figures show that the first mobile 1 is a circular plate 6 surrounded a skirt 7 having an internal wall 8 and an external wall 9.
  • This skirt 7 has a notch 10 arranged in such a way that a finger 11, fixed on the second mobile 3 is able to cross said notch to pass from inside on the outside of the skirt.
  • Figures 6, 7 and 10 show clearly that the second mobile 3 is immobilized in the first position when it is in contact with the first stop 4 and its finger 11 adjoins the internal wall 8 of the skirt 7.
  • Figures 4, 5 and 9 show that the second mobile 3 is immobilized in the second position when it is in contact with the second stop 5 and its finger 11 adjoins the external wall 9 of the skirt 7. It will be observed that the second mobile 3 can be locked in either position with play or without game, this depending on the dimensional ratings given to the various elements involved in the locking device.
  • the present invention may have two embodiments.
  • the first embodiment is illustrated in FIGS. 2 to 8.
  • the second mobile 3 has an angular movement ⁇ and is articulated around a pivot center 12.
  • Figures 2 and 3 show that when the finger 11 of the second mobile 3 faces the notch 10 of the skirt 7 of the first rotating mobile 1, this second mobile 3 can move freely by an angle ⁇ , which brings it from the stop 4 to the stop 5 or vice versa.
  • the Figure 8 shows that the finger 11 is arranged so that the line 13 which connects the pivot center 12 of the second mobile 3 to point 14 for which finger is located midway between the inner 8 and outer 9 walls of the skirt 7 is substantially perpendicular to the straight line 15 which connects the axis 2 of the first mobile 1 at said point 14. It will be observed that this rule of construction is valid whatever the angle ⁇ of displacement of the second mobile 3 and whatever the shape given to finger 11. Likewise, this rule applies regardless of the relationship between the rays centered in 2 and in 12.
  • the second embodiment is illustrated by FIGS. 9 and 10.
  • the second mobile 3 has a rectilinear movement according to arrow R. It can be supported either on the first stop 4 ( Figure 10) or on the second stop 5 (FIG. 9) and its finger 11 moves radially to the first rotating mobile 1.
  • This first mobile comprises, as in the first embodiment a circular plate 6 surrounded by a skirt 7 having internal and external walls 8 and 9. A notch 10 operated in the skirt 7 allows finger 11 to pass from the inner wall to the outer wall of the skirt.
  • the second mobile 3 can be immobilized in a first position (figure 10) when it rests on the first stop 4 and that his finger 11 adjoins the internal wall 8 of the skirt 7, or in a second position (figure 9) when it rests on the second stop 5 and that his finger 11 adjoins the external wall 9 of said skirt 7.
  • FIG. 11 to 13 we can see a wheel exhaust 22 provided with pointed teeth 40.
  • the pallets 16 and 17 cooperate with the teeth 40 of the wheel 22.
  • Pallets have only a rest function and therefore receive no impulse from the teeth of the wheel.
  • the fork 18 cooperates with a dowel 19 mounted on a large plate 20 which rotates around an axis 2 which is also the axis of a balance spring not shown here.
  • the large plate 20 is equipped with an impulse paddle 21 which is propelled, each time alternation, by a tooth 40 of the wheel 22.
  • the stroke of the anchor is limited by two stops 4 and 5.
  • the Robin exhaust uses a classic dart cooperating with a no less classic small tray equipped with a notch.
  • the angular trajectory of the anchor is strongly limited, about 5 °, which leads to the risk of bracing mentioned in the preamble to this description.
  • the present invention provides a solution to the problem that arises and allows therefore to offer a Robin exhaust that can be used industrially and even in series.
  • the large plate 20 is integral with the first rotating mobile 1 cooperating with the second mobile 3, these mobile being executed according to the invention.
  • the mobile 1 comprises a skirt 7 rotating around an axis 2, the connection between the skirt and the axis being preferably carried out by at least one department 6 which replaces the circular plate originally planned.
  • the exhaust is presented just before the start of the pulse.
  • the tooth 41 of the wheel 22 is still at rest on the input pallet 16 of the anchor 3.
  • the large plate 20 and the second mobile 1 linked to it rotate in the direction of arrow A.
  • the anchor or second mobile 3 is driven by the pin 19 and rotates in the direction of arrow B.
  • Finger 11 rotates in the direction of arrow C and is in passing through the notch 10 from the inner wall 8 to the outer wall 9 of the skirt 7.
  • the wheel 22 rotates according to arrow D and tooth 42 gives impetus to the pallet 21 of the large tray 20.
  • the pin 19 then brings the fork 18 resting on the second stop 5 and the tooth 42 at rest on the exit pallet 17.
  • the large plate 20 traverses its arc additional and the second mobile or anchor 3 is immobilized in its second position since pressed on the second stop 5 while the finger 11 adjoins the outer wall 9 of the skirt 7. From this moment, the large plate 20 turn back and turn in the opposite direction to arrow A. His ankle 19 swings the fork 18 of the anchor 3 which bears against the first stop 4, as seen in FIG. 13. The finger 11 then adjoins the inner wall 8 of the skirt 7 and the anchor 3 is immobilized in its first position since pressed simultaneously against the first stop 4.
  • Figures 11 to 13 clearly show the advantages of the invention since the finger 11 linked to the anchor 3 passes from the internal side to the side external of the skirt by the notch 10 formed in said skirt without any risk of snagging or bracing.
