Definitions
- the present invention relates to an escapement disposed between a cog engine and a plate to which is attached a pendulum of a timepiece, the pendulum being able to traverse a free oscillation arc and to receive maintenance pulses oscillations, this escapement comprising first and second gears meshing with each other, one of these wheels being driven by the gear.
- FIG. 1 describes an escapement shown in FIG. 1, arranged, as is usual, between a cog and a plate 2 supporting a sprung balance of a timepiece.
- the balance-balance not shown in the figure, is able, as is known, to to traverse a free oscillation arc and arranged to receive maintenance pulses of these oscillations.
- the cogwheel also called finishing, is the whole wheels and gears which, from a cylinder, transmits the driving force to a wheel exhaust.
- the gear train is represented by its last wheel 30, associated with the pinion 31.
- the wheel 30 drives a first escape wheel 3 by pinion 32 which is attached to it.
- the first wheel 3 meshes with a second wheel 4.
- the wheels 3 and 4 have the same diameter and the same number of teeth.
- the escapement also comprises a rocker 5 capable of receiving pulses generated alternately by the first and second wheels 3 and 4.
- the latch 5 transmits the pulses received at plateau 2 to drive it in rotation so as to maintain the oscillations of the balance-spiral attached to this plate 2.
- the rocker is arranged to block alternatively the first and second escape wheels 3 and 4, this after each pulse has been transmitted to the plateau 2.
- the rocker 5 equipping the exhaust is supported by a pivoting shaft 6 freely in a plate (not shown) that includes the timepiece.
- This flip-flop 5 has a substantially triangular shape.
- a first summit of the rocker defines an edge 19 on which can rest a tooth 8 of the first wheel 3 to subject the rocker 5 to a pulse in a first direction.
- a second vertex of the rocker defines another ridge 19 on which can lean a tooth 10 of the second wheel 4 to subject the rocker 5 to a pulse in a second sense B, inverse in the first sense.
- the edges 19 of the rocker are connected by an edge 14 for blocking, in the vicinity of the edges, alternately the first 3 and second 4 wheels after each pulse transmitted.
- Finally a third top of the rocker 5 has two teeth 11 and 12 likely to mesh with a tooth 13 that includes the plate 2.
- Each of the teeth 8, 10 of the wheels 3 and 4 has a front flank 16 having a first curved top cutout 17 that can support against the edge 14 of the rocker to block one of the wheels, and a second cut 18 in an arc, following the first cut, likely to support against one of the edges 19 to cause the flip-flop 5 in rotation.
- the present invention which has features described in cited document, namely two wheels meshing with each other, one of these wheels being driven by the gear train is intended to provide an escapement for time-keeping having improved chronometric performance.
- Figures 2 to 7 are plan views of six successive phases of the exhaust according to the invention, these phases covering a complete oscillation of the sprung balance.
- the escapement represented in these successive figures stands out of the exhaust of the prior art in the structure of the lever 5 used as well as in the form of the teeth 8 and 10 of the wheels 3 and 4 exhaust. Others elements, common to both escapements, have already been described in Figure 1.
- the rocker 5 equipping the exhaust according to the invention is supported by a shaft 6 pivoting freely in a plate (no represented) that includes the timepiece.
- This flip-flop 5 comprises first and second contact means respectively formed by first 41 and second 42 edges adapted to receive pulses generated alternately by the first 3 and second 4 wheels. It also includes means pulse comprising first and second teeth 11 and 12 susceptible to mesh with a tooth 13 that includes a plate 2 to transmit these impulses to the plateau to drive it in rotation and maintain the oscillations of the balance.
- the plate 2 comprises a lower plate 2a provided of the tooth 13 and an upper plate 2b having a substantially smaller diameter provided with a notch 46 in the form of an arc of a circle opening on the tooth 13 whose function will be explained later.
- first and second formed blocking means by first 43 and second 44 blocking faces to block alternately the first 3 and second 4 wheels after each pulse transmitted.
- first 41 and second 42 edges and the first 43 and second 44 faces blocking devices are provided on the periphery of the rocker 5 in remote regions each other.
- This rocker 5 preferably has a substantially symmetrical shape relative to an axis (X-X) passing between the first and second teeth 11 and 12 of the rocker and the center of the shaft 6.
- the first and second means of contact are arranged symmetrically with respect to this axis (X-X) as well as the first and second blocking means.
- angle (a) formed by the segment connecting the first of contact in the center of the shaft and the segment connecting the second contact means to the center of the tree is an acute angle preferably between 50 ° and 70 °.
- This angle (a), shown in Figure 2 is preferably equal to 60 °.
- angle (b) formed by the segment connecting the first locking means in the center of the shaft and the segment connecting the second locking means in the center of the shaft is an obtuse angle preferably included between 130 ° and 170 °.
- This angle (b), represented in FIG. 3, is advantageously equal at 155 °.
- the first edge 41 forming the first contact means co-operates with the end of a tooth 8 of the first wheel 3 to subject the rocker 5 to a pulse in a first direction (B) (see Figure 3).
- the second edge 42 forming the second contact means cooperates with the end of a tooth 10 of the second wheel 4 to subject the rocker 5 to a pulse in a second direction (A), reverse in the first sense (B) (see Figure 7).
- the first locking face 43 cooperates with the end of a tooth 8 of the wheel 3, adjacent to the tooth 8 having previously served to subject the rocker to a pulse in the direction B, to block the rocker (see Figure 4).
- the second locking face 44 cooperates with the end of a tooth 10 of the wheel 4, close to the tooth 10 having previously served to subject the rocker to a pulse in the sense A, to block the rocker.
- each of the teeth 8, 10 respectively of the first 3 and second 4 wheels has a front flank 16 having a cutout 21 curved likely to cooperate respectively with the first 43 and second 44 blocking faces of the rocker to block one of the wheels, and also able to lean respectively against the first 41 and second edges 42 of the rocker to cause the rocker in rotation.
- a tab 45 preferably having a end terminated in a point, placed in a plane parallel to that in which the teeth 11 and 12 of the rocker. So, during the free oscillation arc, the tongue 45 prevents a reversal of the rocker 5 for example in case of shock by the blocking the latter at the periphery 20 of the upper plate 2b.
- the mechanism is stopped.
- the second escape wheel 4 is blocked because the curved cut 21 of its tooth 10 is in contact with the second face 44 of blocking the rocker 5.
- the angular excursion of the rocker 5 is exhausted since its tooth 12 is in abutment on the pin 26.
- the balance-spring is close to the end of oscillation (arrow E) or near the end of second alternation of this oscillation.
- the tooth 13 of the plate 2 comes into contact with the tooth 11 of the flip-flop 5 and will cause said flip-flop in the direction of the arrow B.
- This is a phase of disengagement of the rocker where on the one hand the tooth 12 is driven so as to away from the pin 26 and where on the other hand the second face 44 blocking the flip flop can fade in front of curved cutout 21 of tooth 10.
- flip-flop 5 is the same as that described above at except that the tongue 45 prevents any overturning.
- the plateau 2 continues to turn in the direction of arrow E and go through the first half of his second free oscillation.
- the rocker 5 and the first and second wheels 3 and 4 are always blocked.
- the plateau 2 comes back inverse shown by the arrow M and goes through the second half of his second free oscillation.
- the rocker 5 still blocks the first and second wheels and is always prevented from overturning thanks to the tongue 45.
- first and second escape wheels have a structure making it possible to have more teeth at their periphery, thus the necessary torque for driving the barrel is less important and therefore the energy consumed is lower.
