Definitions

  • the present invention relates to a manual control device for a watch and more particularly to such a device comprising a sliding lock on the outer surface of a watch case, in particular for controlling or arming a repeating mechanism.
  • FIG. 1 shows a control device of a watch of the aforementioned type belonging to the prior art and corresponding to patent CH 672 868.
  • This control device comprises a latch 2 sliding on the outer surface 4 of a watch case 6 and mechanically connected through an oblong opening 8, formed in the box 6, to a slider 10 which cooperates with a rack arm (not shown) for controlling the ringing of a repetition.
  • a seal 12 is disposed between the slider 10 and the inner wall 14 of the box 6.
  • This control device further comprises locking means 16 of the lock 2 movable relative thereto, between a first position in which the seal 12 is compressed between the slide 10 and the wall 14 to seal the control device, and a second position in which the seal 12 is not compressed and allows the displacement of the lock 2 relative to the box 6 to cause the command of the ring.
  • the latch 2 comprises a groove 18 in which a locking member 20 slides.
  • This member 20 comprises a stop 22, an oblong hole 24, a thin portion 26 extending in the lock 2, connected via a ramp 28 at a portion of greater thickness 30 emerging from the latch 2.
  • a screw 32 connects, through the wall 14 and the hole 24, the latch 2 to the slider 10, a self-lubricating pad 34 being interposed between the member 20 and the latch 2.
  • a seal 36 is also provided between the head of the screw 32 and the slider 10.
  • the latch 2 is in position rest, the seal 12 is compressed and the lock 2 can not be moved.
  • the user moves the member 20 with his fingernail in the direction of the arrow F relative to the box 6 and the latch 2 until the stop 22 come into contact with the shoe 34.
  • the portion 26 of the member 20 is then at the right of the shoe 34, the seal 12 is decompressed and the lock 2 can be moved in the opposite direction to the arrow F, driving with it the slider 10, which causes the arming mechanism to repetition.
  • the latch 2 is released, it is brought back into the rest position by return means, causing during its movement the actuation of the repetitive mechanism and, thereby, the successive ring of hours, quarters and minutes in the case of a minute repeater.
  • this device has the significant risk that the lock 2 is blocked before reaching its rest position during its recall to this position, thus leading to an incomplete ring of minutes, quarters or hours.
  • the large surface of the seal 12 as well as the nature of the material of which it is formed, in this case neoprene has a significant coefficient of friction with respect to the wall 14, which risks locking the lock 2 in a intermediate position if it is not accompanied manually. This risk is also increased because of the presence of the ramp 28 that must go up the pad 34 so that the latch 2 returns to its rest position.
  • control device requires the user to exert a relatively large force on the locking member to release the latch 2, at the risk of getting hurt or even breaking the nail.
  • the main object of the present invention is therefore to overcome the drawbacks of the abovementioned prior art, by providing a watch comprising a manual control device, in particular for arming a repetitive mechanism, having a reliable operation.
  • the object of the invention is also to provide a watch comprising a manual control device which makes it possible to ensure in a simple and economical way the tightness of the inside of the box with respect to the outside of that -this.
  • the invention also aims to provide a watch comprising a manual control device that is easy to handle for the user, without harming the aesthetic appearance of the watch.
  • the subject of the invention is a watch as defined by claim 1 of the patent.
  • the wristwatch schematically shown in Figures 2 and 3 conventionally comprises a box 100 formed of a middle part 102 of generally circular shape on which is mounted a manual control device according to the invention and designated by the general reference 104.
  • the control device 104 comprises a lock 106 sliding on the outer surface 108 of the middle part 102 of the box 100.
  • the surface 108 forms the bottom of an elongate housing 110 provided in the middle part 102.
  • the surface lower 112 of the lock 106 matches the shape of the bottom 108, the shapes of this lower surface 112 and those of the bottom 108 being such that the lock 106 can slide relative to the bottom 108.
  • the bottom 108 comprises an oblong opening 114 through which a screw 116 which mechanically connects the latch 106 to a slider 118 controlling, via a pin 120 an arm 122 which allows the arming of a repeating mechanism not shown repetition.
  • the length of the opening 114 defines the useful stroke of the lock 106 to perform the arming of the desired function. In the case of arming a repeating mechanism, the length of this opening 114 is typically equal to about half the length of the lock 106.
  • the slider 118 has an upper surface 124 which matches the shape of the inner surface 124 of the middle part 102, the shapes of these surfaces 124, 126 being such that the slider 118 can slide along the internal surface 126.
  • a rod 128 extends along an arc of a circle in the longitudinal extension of the slide 118, the free end 130 of this rod 128 sliding in an orifice 132 of a tongue 134 extending perpendicularly to the inner surface 126 of the middle part 102.
  • a helical spring R is wound around the rod 128 and extends between the tongue 134 and the slide 118, to return the latter to a determined position shown in FIG.
  • the control device 104 further comprises a seal 136 disposed between the outer surface 108 of the middle part 102 and the lower surface 112 of the lock 106, and extending at least around the 114.
  • the seal 136 has substantially the shape of a strip which completely covers the surface of the opening 114, the width of this band being greater than the width of the opening 114, and its length being substantially equal to that of the latch 106.
  • the seal 136 is therefore sealed through the screw 116.
  • the seal 136 is preferably made of elastomer or rubber, but any other synthetic or natural material generally used for the realization seals in the field of watchmaking can be envisaged.
  • the seal 136 is associated with a blade 138 movable relative to the lock 106 while being fixed thereto at a point, the blade 138 being of course also traversed by the screw 116.
  • the blade 138 is an elastic blade and the seal 136 is secured to it, for example by gluing. More specifically, the seal 136 and the blade 138 extend in an oblong recess 140 cut into the lower surface 112 of the lock 106 lying opposite the middle part 102.
  • the blade 138 is fixed in the bottom of the recess 140 by one of its ends, for example using a screw 142, and its free end is resiliently biased towards this bottom. It will be noted in this connection that, preferably, the head of the screw 142 is embedded in the blade 138 and that the seal 136 covers this screw head 142.
  • the control device 104 further comprises control means 144 associated with the latch 106 to move the device 114 from a first state, said rest state in which the lock 106 is blocked, to a second state called the state of arming in which the lock 106 is unlocked.
  • the lock 106 In the idle state, the lock 106 can not slide freely relative to the box 100 and the seal 136 is compressed against the outer surface 108 of the middle part 102 (FIG. 4), so that the sealing of the box 100 vis-à-vis the outside is assured.
  • the lock 106 In the state of arming, the lock 106 can slide freely with respect to the box 100 and the seal 136 is not compressed (FIG.
  • the control means 144 comprise a lever 146 hinged about an axis 148 secured to the lock 106, this lever 146 making it possible to move the control device 104 from the state of arming to the state of rest and vice versa.
  • the lever 146 includes a handling portion 146a and a control portion 146b that acts on the blade 138 and is formed of an eccentric. It is also seen in the figures that the lever 146 extends in a housing 150 dug in the outer surface 108 of the lock 106 facing outwardly relative to the middle part 102.
  • This housing 150 opens into the oblong recess 140, the part eccentric 146b of the lever 146 extending partially into the recess 140 to come into contact with the blade 138.
  • the point of contact of the eccentric portion 146b with the blade 138 is remote from the attachment point of the blade 138 on the lock 106 and is preferably close to the free end of the blade 138.
  • the shape of the profile of the eccentric portion 146b is arranged so that, in the rest position the part 146b acts on the blade 138 and the seal 136 and applies them firmly against the outer surface 108 of the middle part 102 to block the sliding of the lock 106 and that, in the arming position, the portion 146b is erased sufficiently so that the The blade 138 and the seal 136 emerge from the outer surface 112 and become lodged in the recess 140, which then allows the bolt 106 to slide relative to the middle part 102.
  • the lever 146 in the position at rest, is preferably embedded in the housing 150 so as to be flush with the outer surface of the latch 102 and that, in the arming position, the lever 146 protrudes with respect to the latch 102 and extends substantially perpendicular to the outer surface 108 of the lock 106, thus facilitating the handling of the control device 104 by the user.
  • the contact point C of the profile 146b with the blade 138 is substantially offset with respect to the vertical V of the hinge axis relative to to the blade 138, which keeps the lever 146 in a stable position in the housing 150 without any additional means.
  • the profile 146b is arranged so that the lever is stably maintained in the position described above.
  • the profile 146b comprises a first domed portion 152 whose apex is offset with respect to the vertical axis 148 relative to the blade 138. so that during the passage of the lever 146 from its position corresponding to the state of arming of the device 104 to its position corresponding to the state of rest of the device 104, the top of the portion 152 passes to the axis of the axis 148 relative to the blade 138 and continues beyond to reach a stable equilibrium position in which the blade 138 is applied against the middle part 102.
  • the first portion 152 is followed by a second portion 154 substantially flat against which the elastic blade 138 is applied in the arming position.
  • the lever 146 thus has two stable positions according to the control device 104 is in the state of rest or arming.
