Definitions

  • the present invention relates to a pusher device for a timepiece and more particularly to such a device in which the pusher head has a pattern or a logo on its end face and in which the pattern can be oriented as desired.
  • a pusher device for a timepiece typically comprises a cylindrical tube inside which is disposed longitudinally and passing through a pusher provided with a head having a lower face which abuts against a first shoulder formed in the tube when a pressure manual is exerted on the head and a rod terminated at its end by a stopper, typically a screw, limiting the axial swing of this rod in the tube.
  • a seal generally surrounds the rod and a coil return spring is wound around the rod to return the pusher to a predetermined position.
  • Pushers executed according to the above description are well known in the state of the art. They are used, for example, in chronographs or even wristwatches to correct, for example, the date. They are called pushers when they protrude from the middle part and allow a function to be corrected when pressed with a finger. When the pressure ceases, they return to their original position. They are rather called correctors when they are drowned in the middle.
  • the object of the present invention is to remedy the drawbacks of the aforementioned prior art by providing a push-button device of simple and economical construction and of which the push-button head comprises on its end face a pattern such as a logo or a mark. and wherein the position of the logo or mark affixed to the end face of said head can easily be adjusted to a precise determined angular position or orientation.
  • the invention also relates to a watch case comprising a push-button device as described above.
  • a pusher device 1 comprising an orientable pusher head 2a and intended to be mounted by driving or screwing into the side wall of a watch case middle part (not shown).
  • FIG. 1 which is a top view of the push-button device 1, we can distinguish an inscription "LOGO", arranged on the external face 2a of the head 2b of the push-button 2.
  • the push-button device 1 comprises orientation adjustment means which will be described later using the figures 2 to 4 .
  • the inscription L “LOGO” is adjusted in a perfectly horizontal position corresponding preferably to the plane of the middle part of the watch on which the push-button device 1 is mounted.
  • the pusher device 1 comprises a pusher 2 which is provided at a proximal end with a pusher head 2b to allow a user to actuate it.
  • the pusher head 2b is integral with a central rod 3 which ensures at a distal end the connection between the inside and the outside of the watch case.
  • the pusher head has a smooth, circular recess 2c surrounding the proximal part of the central rod 3.
  • the push-button device 1 further comprises a tube 4 of generally cylindrical shape intended to be assembled to a watch case.
  • the tube 4 is intended to be driven by its lower part 4a into an opening in the middle part of a watch case.
  • the tube 4 has an upper part 4b of greater diameter than that of the lower part 4a.
  • the tube 4 comprises in the lower zone of its upper part an annular groove 5 in which is housed an O-ring 6 ensuring its sealing at the middle part.
  • the tube 4 can either be terminated by an upper portion emerging from the middle part or be embedded in the middle part.
  • the tube 4 has a first internal diameter defining a first housing 7a extended by a second internal diameter smaller than the first diameter and defining a second housing 7b and an internal shoulder 7c.
  • the pusher head 2b is partially engaged in the housing 7a in the rest position of the pusher and can engage further until it comes into abutment against the shoulder 7c when the pusher is actuated by the user's finger.
  • the central rod 3 is arranged inside the tube 4 so as to be able to slide along its longitudinal axis A and to be able to rotate freely in the tube 4.
  • the pusher device 1 further comprises a helical return spring 10 which surrounds the proximal portion of the rod 3 and which is partially housed in the recess 2c and in the housing 7a.
  • the spring 10 is intended to oppose the axial push of the user's finger on the pusher head 2b.
  • the spring 10 is mounted compressed between the bottom of the recess 2c and the inner shoulder 7c of the tube 4.
  • the inner shoulder 7c comprises a central circular recess 11 which receives a washer 12 surrounding the central rod. 3.
  • the washer 12 also rests on a pair of seals 13 between which is interposed a washer 14
  • the central rod 3 has at its distal end, projecting out of the housing 7b, an annular groove 15 in which is arranged an elastic ring 16 which abuts against the distal end of the tube 4.
  • the ring elastic 16 thus forms a stopper for the pusher 2 in the tube 4.
  • the distal end of the tube 4 ends with a third diameter smaller than the second diameter and defining on the one hand a passage for the distal end of the central rod 3 and on the other hand a second internal shoulder 4c.
  • the push-button device further comprises a device for adjusting the angular orientation of the push-button head 2b relative to the watch case.
  • the adjustment device comprises a friction ring 17 arranged concentrically around the central rod 3.
  • the friction ring is arranged between the washer 14 and the second shoulder 4c and in the example illustrated the friction ring 17 is arranged more particularly between the lower annular seal 13 and the shoulder 4c. It goes without saying that in a variant the friction ring 17 could be arranged between the upper annular seal 13 and the washer 14.
  • the friction ring 17 has a cylindrical outer surface 17a whose diameter is tightly fitted to the inner wall of the housing. 7b of the tube 4, therefore in frictional contact with this wall.
  • the friction ring 17 comprises a central opening 17b of polygonal shape in this case hexagonal and the central rod 3 has a polygonal section complementary to the opening 17b in order to make the rod 3 integral in rotation with the ring 17 while allowing the rod to maintain a free translational movement in the opening 17b.
  • the central rod 3 comprises in its distal face 3a a slot 18 intended to cooperate with the end of a tool to actuate the central rod 3 in rotation against the frictional forces induced by the ring in order to adjust the angular orientation of the pusher head 2b.
  • the slot 18 therefore acts as a means for actuating the pusher 2 in rotation, which makes it possible to make it pivot and thereby to be able to adjust the angular orientation of its head 2b in a determined angular position.
  • the surface of the inner wall and / or the cylindrical outer surface 17a of the ring can be textured to adjust the appropriate friction torque.
  • the friction fit of the friction ring 17 on the inner wall of the housing 7b will be chosen so that the friction torque generated by the friction ring inside the tube 4 is greater than the screwing torque of l. 'nut on the central rod 3.
  • the nut would have a dual function, namely to form, on the one hand, the stop member of the pusher and, on the other hand, the actuating means of the latter to rotate and orient it angularly.
  • the method of mounting the push-button device and orientation of the push-button is as follows.
  • the push device 1 fully assembled with the elastic ring 16 in abutment against the distal end of the tube 4 is driven out or screwed into an opening in the middle part of the watch case.
  • the central rod 3 can be actuated in rotation by means of a tool inserted into the slot 18 from the inside of the middle part and drive the pusher head in rotation .
  • the pusher head in turn drives the friction ring 17 via the connection by polygonal section between the opening 17a and the section of the central rod 3 in the desired angular orientation.
  • the ring 17 rotates in the tube 4 against the retaining friction torque present between the outer surface 17a of the friction ring 17 and the lower housing inner wall 7b of the tube 4.
