Definitions

  • the present invention relates to a detent escapement for a timepiece comprising an escape wheel provided with teeth, a balance wheel on the axis of which are fixed a large plate equipped with a pulse pallet and a first actuating finger and a small plate on the circular periphery of which a notch is made, and a wedge-shaped blocker articulated on an axis, this blocker carrying a locking device of the escape wheel and a second actuating finger .
  • a detent escapement broadly in line with the above description has already been proposed and described in the old Swiss patent CH-3299 due to Emile James.
  • the proposed arrangement shows a trigger-rocker pivoted at one of its ends according to a conventional construction of this kind of exhaust.
  • the axis of the balance carries a large plate, a first small plate carrying a notch and a second small plate carrying an actuating finger.
  • the weighing lever has a locking device for the escape wheel - in this case a pallet of rest -, a pin, a spout and a leaf spring.
  • the trigger-rocker is brought to rest by a spiral return spring. As the actuating finger lifts the trigger with the leaf spring, the nose enters the notch at the same time as the escape wheel advances one step. During the additional arc, the beak is clear of the notch and is near the circular periphery of the first small plateau.
  • This arrangement has the advantage of preventing a tooth of the wheel from leaving the pallet rest when the timepiece receives a shock. At this time indeed, the spout is pressed briefly against the circular periphery of the first small plate, which stops the trigger-rocker which is immediately returned to rest by the spiral spring return.
  • the detent escapement is suitable for large timepieces which make it possible to have large balance wheels with a large reserve of energy and a high torque for actuating the elastic member acting on the trigger. .
  • the object of the present invention is to propose a timepiece of small dimensions, for example a wristwatch that is equipped with a detent escapement to replace, for example, the classic anchor escapement and to benefit from the advantages conferred by this escapement relaxation.
  • a timepiece of small dimensions for example a wristwatch that is equipped with a detent escapement to replace, for example, the classic anchor escapement and to benefit from the advantages conferred by this escapement relaxation.
  • the expansion escapement of the present invention is remarkable in that there is no elastic member acting on the trigger.
  • the detent escapement of the invention in addition to meeting the definition of the first paragraph of this description, is characterized in that the first and second actuating fingers are shaped in such a way that when the large and small trays rotate in a first direction, the first finger causes the second finger which bypasses a first side said first finger to disengage the locking device of the escape wheel, the second finger being then driven by a rising edge which is provided with the notch of the small plate to reengage the locking device in the escape wheel, and such that when the large and small trays rotate in a second direction, opposite the first direction, the first finger causes the second finger which bypasses a second side, opposite the first, of said first finger to maintain the engagement of the locking device in the escape wheel.
  • the Figures 1 to 3 illustrate the escapement relaxation object of the present invention according to a first embodiment.
  • the exhaust comprises an escape wheel 2 provided with teeth 3. Without being shown in the drawings, the escape wheel is driven by the wheel of the timepiece which receives its driving force from a cylinder.
  • On the axis 16 of the balance (not shown) is fixed a large plate 4 which is equipped with a pulse pallet 5 and a first actuating finger 14.
  • On the same axis 16 is fixed a small plate 23 with a circular periphery 24 and a notch 22.
  • the figures also show that the exhaust comprises a blocker 6 in the form of rocker hinged on an axis 8.
  • the blocker 6 carries a locking device or a pallet 7 and a second finger actuator 11.
  • first and second actuating fingers 14 and 11 are shaped such that, when the large and small trays 4 and 23 rotate in a second direction b, opposite to the first, the first finger 14 drives the second finger 11 bypassing a second side 21 , opposite the first, of said first finger 14, which has the effect of maintaining the engagement of the pallet rest 7 in the escape wheel 2.
  • tooth 62 has come into contact with the rest pallet 7.
  • the tip of the tooth 62 pushed by the kinetic energy of the wheel 2, is housed on a rest line 33 of which the pallet 7 is provided.
  • the face 30 (see also figures 1 and 2 ) against which abuts a tooth of the wheel 2 comprises a first rest plane 31 located at the front of the pallet 7 and a second rest plane 32 located at the rear, this second plane being inclined relative to the first for
  • the point of the tooth 62 by pulling effect is housed on the line of rest 33 and stops there, the second rest plane 32 standing in front of it. preventing him from continuing his journey. It will be observed that this device allows to do without stop pin that is generally available to limit the frog of the blocker.
  • the different phases of operation remain the same as those exposed and illustrated in Figures 4 to 13 .
  • the tip of the tooth 62 by pulling effect is housed on the line of rest 44 and stops there, the second rest plane 43 standing in front of it, preventing it from continuing on its way.
  • the Figures 17 to 19 illustrate the detent escapement according to a third embodiment.
  • the single pallet of the first embodiment has been replaced by first and second pallets 50 and 51 cooperating respectively with first and second teeth 62 and 63 of the escape wheel 2.
  • the first and second pallets rest respectively have first and second rest planes 52 and 53 inclined relative to each other.
  • the locking device is interposed between the teeth of the escape wheel, it is the first rest plane 52 of the first pallet 50 which intercepts the first tooth 62 of the wheel 2.
  • This wheel is then blocked while done when the second rest plane 53 of the second pallet 51 comes into contact with the second tooth 63 of the wheel 2, the inclination of the rest plane 52 being chosen such that the climbing of the tooth 63 along said plan 52 is not possible.
  • the second tooth 63 climbs the second rest plane 53 of the second blade 51 forcing the wheel 2 to move back slightly against the driving force that exercise on it.
  • the second tooth 63 finally returns to the first point of contact of the second rest plane 53 with the second tooth 63, when the second finger 11 leaves the first finger 14.
