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 is fixed at least one plate comprising a pulse pallet and in the circular periphery of which is made a notch, and a blocker in the form of rocker hinged on an axis, this blocker carrying means for locking the escape wheel, a control finger and a probe terminated by a spout arranged to cooperate with the notch of said at least one tray.
the main object of the present invention is to overcome the drawbacks of the abovementioned prior art by providing a detent escapement having improved impact resistance enabling it to be easily integrated into a wristwatch.
the subject of the present invention is a detent escapement for a timepiece comprising an escape wheel provided with teeth, a balance wheel on the axis of which is fixed at least one plate comprising a pulse pallet and in the circular circumference which is practiced a notch, and a blocker in the form of a rocker articulated on an axis, this blocker carrying means for blocking the escape wheel, a control finger and a probe terminated by a spout arranged to cooperate with the notch of said plate, characterized in that said plate further comprises a security finger arranged to cooperate with the teeth of the escape wheel and block the latter when the pulse pallet is released by accident of the teeth of the wheel exhaust.
the safety finger is interposed in the path of the wheel of exhaust for block his race. This avoids any accidental release of said wheel and thereby any risk of damage to the drive mechanism and exhaust of the watch.
the safety pin is placed at an angular distance ⁇ of the pulse pallet less than or equal to 40 °, preferably between 30 and 40 ° and even more preferably from the order of 35 °. Indeed, it will be readily understood that if the angular space between the pulse pallet and the safety pin is too small or too large, the tooth of the escape wheel will not be intercepted.
the accompanying figures illustrate the escapement relaxation object of the present invention. It comprises an escape wheel 2 provided with teeth 3. Without being shown, the wheel 2 is driven by the wheel of the timepiece which receives its driving force from a barrel. Trays 1 are mounted on the axis 16 of a pendulum not shown in the figures. These plates 1 comprise a large plate 4 equipped with a pulse pallet 5 and a small plate 23 provided with a circular periphery 24 in which is made a notch 22 having a rising edge 25. A first actuating finger 14 overcomes The figures show that this finger 14 emerges from a disk 75 sandwiched between the plates 4 and 23.
the exhaust further comprises a blocker 6 in the form of a rocker articulated on an axis 8.
the blocker 6 comprises first and second parts connected firmly by the axis 8.
the figures show that the first part comprises locking means 80 cooperating with the teeth 3 of the escape wheel 2 and that the second part comprises a second actuating finger 11 arranged to cooperate with the first finger 14, and a probe 20 terminated by a beak 21 arranged to cooperate with the rising edge 25 of the cut 22 made in the small plate 23.
one of the trays further comprises a safety pin 95 arranged to cooperate with the teeth 3 of the escape wheel 2 and block the latter when the pulse pallet 5 is disengaged by accident. the teeth of the escape wheel 2.
the radius connecting the center 16 of the plates 1 to the safety pin 95 and the radius connecting the same center to the top of the pulse pallet 5 form an angle ⁇ of between 30 ° and 40 ° ° to ensure a good interception of the teeth of the wheel in case of accidental reversal of the trays.
the first and second actuating fingers 14 and 11 are fixed respectively to the large plate 4 and to the blocker 6 and are arranged to cooperate with each other in such a way that when the plates 1 rotate in a first direction, the first finger 14 causes the second finger 11 to disengage the locking means 80 of the escape wheel 2, the nose 21 of the probe 20 being then driven by the rising edge 25 of the notch 22 to re-engage the locking means in the wheel of exhaust, and such that when the plates 1 rotate in a second direction, opposite the first, the first finger 14 drives the second 11 to maintain the blocking means 80 engaged in the escape wheel 2.
the locking means 80 have first and second pallets 50 and 51 arranged next to each other. These pallets respectively have first and second rest planes 34 and 35. These rest planes are inclined relative to each other to form a rest line 36.
the first plane 34 intercepts a tooth 62 of the wheel 2 when the probe 20 is driven by the rising edge 25 of the notch 22, the trays 1 rotating in a first direction. Following this tooth 62 comes to rest on the line of rest 35.
the second plane 35 is then scaled by the same tooth 62 when the first finger 14 drives the second finger 11, the plates 1 rotating in a second direction. Finally tooth 62 returns to the line of rest 35 when the second finger leaves the first.
the beginning of the impulse is presented in FIG. 4.
the wheel 2 released from the pallets 50 and 51, starts to rotate in the direction of the arrow e, which is moved by the driving force imparted to the wheel by the barrel .
the tooth 61 of the wheel 2 meets the pulse pallet 5 equipping the large plate 4 and restarts the plates 1 in the direction of the arrow a.
the wheel 2 continues to rotate in the direction of the arrow e and continues to drive the trays 1 by the action of the tooth 61 on the impulse pallet 5 until the tip 21 of the probe 20 enters into position. contact with the rising edge 25 of the small plate 23. From this moment the blocker 6 is driven in the direction of the arrow h.
FIG. 7 illustrates the end of the pulse of the tooth 61 on the pallet 5.
the spout 21 has passed the rising edge 25 of the notch 22 made in the small plate 23 and is then resting on the circular periphery 24 of this small plateau.
Blocker 6 continues to be driven in the direction of arrow h and arrives at the end of return.
the tooth 62, driven in the direction of the arrow e is about to be intercepted by the locking means 80.
Figure 8 shows the taking of rest.
the tooth 62 bears against the first rest plane 34 of the first rest pallet 50.
FIG. 9 shows the total rest of the tooth 62 against the blocking means constituted here by the first and second pallets of rest 50 and 51.
the tip of the tooth 62 pushed by the kinetic energy of the wheel 2, is housed on the line of rest 36 formed by the inclination of the first and second planes of rest 34 and 35 belonging respectively to the first and second pallets of rest 50 and 51. This is the pull effect well known to watchmakers.
the tooth 62 is thus housed on the rest line 36, the second rest plane 35 standing in front of this tooth and preventing it from continuing on its way.
FIG. 10 the exhaust is shown at the end of the additional reverse arc, ie towards the end of the second alternation.
Trays 1 rotate in the direction of the arrow b.
the figure shows the situation when the second finger 14 which overcomes the large plate 4 comes into contact with the first finger 11 mounted on the blocker 6. The latter is still and the tooth 62 of the wheel 2 is always housed on the rest line 36 of the pallets 50 and 51.
the trays 1 have continued their course in the direction of the arrow b and the second finger 14 has slid on a bevel 90 made at the end of the first finger 11 which causes the blocker 6 to rotate in the direction of the arrow h.
the tooth 62 of the wheel 2 climbs the second rest plane 35 of the second rest pallet 51, which drives the wheel 2 in a slight recoil movement noted here by the arrow g.
Figures 14 to 17 are plan views explaining the operating phases of the exhaust illustrated in Figure 1 in the case of an impact applied to the timepiece.
Figure 14 is identical to Figure 4 and illustrates the beginning of the pulse.
the wheel 2, released from the pallets 50 and 51 starts to rotate in the direction of the arrow e, it is moved by the driving force imparted to the wheel by the barrel.
the tooth 61 of the wheel 2 meets the pulse pallet 5 equipping the large plate 4 and restarts the plates 1 in the direction of the arrow a.
FIG. 16 shows that from the situation presented in FIG. 15, nothing holds the wheel 2 to rotate in the direction in which it is normally driven by the gear train (arrow e) and FIG. safety 95 was not present, wheel 2 would continue to turn wild causing serious damage to the exhaust and drive mechanism.
the top of the tooth 61 hits the safety pin 95 which reverses the direction of rotation of the plates 1 and thereby restores the correct direction illustrated by the arrow a.
Figure 17 shows the situation where the tooth 61 leaves the safety pin 95, which will allow the tooth 63 to give a new impetus to the pallet 5.
the safety finger 95 is situated at the same level as the pulse pallet 5, this level being able to be that of the large plate 4.
This Safety finger 95 can be made in one piece with the plate 4 or reported on the latter in the form of a stone set in the image of the impulse pallet 5.
