Definitions

  • the subject of the present invention is a lockable waterproof pusher especially for a watch case that ensures normal sealing operating pressure of approximately 10 bars in the active position and a super-tightness of around 100 bars in the locked rest position.
  • Another object of the present invention is to provide a sealed pusher in which the sealing members, generally one or more seals, are located in such a way that they protect not only the inside of the box from shows but also the mechanism of the pusher itself.
  • Yet another object of the present invention is to provide a pusher waterproof, especially for watch cases, which is simple, robust, has a reduced number of parts and requires no maintenance.
  • a waterproof pusher for document diving watch CH 624 259 which comprises on the one hand a tube screwed into the watch case and on the other hand a pusher head sliding in this tube tightly using a seal, this pusher head being intended to be integrally connected to a thrust member acting on a mechanism.
  • the pusher head has a annular recess in which is housed an axially sliding bushing but not angularly on the outside of the tube and cooperating with the pusher head by a screw thread.
  • a second seal surrounding the pusher head core can be forcibly applied against the head tube and core when the socket is moved by a rotation of the head towards the tube.
  • This device has drawbacks, the main ones being require several moving parts and several seals at several levels of the device, these seals do not protect the pusher mechanism itself since water or dust can get between the head and the socket of the mechanism.
  • a rotation of the head is necessary, rotation which also causes a corresponding rotation of the thrust member. This can lead to wear of the watch mechanism actuated by the pusher, which is undesirable.
  • the present invention relates to a lockable waterproof pusher allowing achieve the goals set out above and obviate the disadvantages of the devices existing.
  • the lockable waterproof pusher according to the present invention is distinguished by the characteristics set out in claim 1. Other characteristics of this lockable waterproof pusher are listed in the claims dependent.
  • the attached drawing illustrates schematically and by way of example a shape execution of the lockable waterproof pusher according to the invention.
  • Figure 1 is an axial section of the pusher in the locked position.
  • Figure 2 is an axial section of the pusher in the service position unlocked but in its inactive position for which it does not operate the mechanism he controls.
  • Figure 3 is an axial section of the pusher in the service position unlocked but in its active position activating the mechanism it controls.
  • Figure 4 is a sectional view of the pusher along line A-A of the figure 1.
  • the pusher waterproof lockable intended to equip in particular a watch case comprises a pusher tube 1 comprising a lower male part of small diameter 2 and an upper male part 3 of larger diameter, separated by a shoulder 4.
  • the lower male part 2 is intended to be driven into a hole in the middle of a watch case.
  • the upper male part 3 has on its peripheral surface exterior a groove 5 intended to receive one or two seals 6.
  • This upper male part 3 has a bore 7 having a shoulder internal 8, circular bore extending into the lower male part 2 and ending with a hexagonal portion 9.
  • the pusher further comprises a tubular pusher body 10 having an internal annular rib 11 forming a stop.
  • Upper body 11 has a thread 12 on the internal wall of the body while the part bottom of this body has a recess whose inner wall has a cylindrical part 13 and a conical part 14 both cooperating with the joints 6.
  • the distance separating the lower face of the rib 11 from the front face lower part of the body 3 corresponds to the distance separating the shoulder 4 from the tube 1 of its upper front face. So when this underside of the rib 11 abuts against the upper front face of the tube 1, the front annular face of the body 10 is located substantially in the same plane as the shoulder 4 of the tube 1.
  • the pusher also has a pusher axis 15 whose end upper comprises a head 16 provided on its periphery with a cooperating thread with the internal thread 12 of the body 10 and on its underside with a circular groove 17.
  • the lower part of this pusher axis 15 has an end part hexagon socket engaged in the lower end 9 hexagon socket of the tube 1.
  • the lower end of the pusher axis 15 has an axial thread 18 intended to receive a retaining screw 19.
  • a return spring 20 is arranged around the pusher axis 15 and takes support on the one hand at the bottom of the groove 17 of the head 16 of this pusher axis and on the other hand on the internal shoulder 8 of the pusher tube and tends to move away axially the head 16 of the pusher axis 15 of the pusher tube 1.
  • the head of the retaining screw 19 abuts against the lower front face of the tube 1 limits the axial travel of the possible movement of the pusher axis 15 relative to the tube 1 defining the inactive position of the pusher (fig. 1 and 2).
  • the pusher further comprises a pusher cap 21 driven out and glued on the upper part of the pusher body 10 practically unremovable.
  • the pusher is illustrated in the locked position, the cap 21 and the body 10 forming a whole is screwed onto the head 16 of the pusher axis.
  • This axis cannot rotate in push tube 1 due to the six-part sides of its end cooperating with the hexagonal bore of the tube.
  • the head of the retaining screw 19 abuts against the free front face of the pusher tube 1.
  • the user unscrews the cap assembly 21 and body 10.
  • This assembly moves relative to the tube 1 and to the axis of pusher 15 until the head 16 of this pusher axis 15 abuts against the internal rib 11 of the body.
  • the seals 6 In this position illustrated in FIG. 2, the seals 6 always seal although they are less compressed since they do not are more in contact with the conical part 14 of the body 10. This seal reduced operating, is of the order of 10 bars.
  • the user can activate the push-button function by pressing on the cover 21 causing the axial displacement of the pusher axis 15 relative to the pusher tube 1 against the action of the spring reminder 20 to arrive in the active position illustrated in Figure 3 where the screw holding 16 activates a mechanism.
  • This active axial position of the pusher is limited by the contact of the internal rib 11 of the body 10 with the surface top of pusher tube 1.
  • This lockable waterproof pusher is particularly advantageous in that it is very simple and robust, that the number of its parts is reduced and its use is simple and reliable.
  • this pusher is that the or the seals are placed in one place between the pusher tube 1 and the body of pusher 10. This seal is therefore upstream of the pusher mechanism itself in relation to the flow of water or dust that could penetrate between the tube and body.
  • the thread between the head 16 of the pusher axis and the body 10 as well as the return spring 20 are also protected from contamination external, which is not the case in the previous pushers.
  • Another advantage of this pusher is that the pusher rod 15 cannot move angularly relative to the pusher tube 1, this which reduces the wear that the mechanism controlled by such a pusher can undergo.
  • the axial distance x by which the cap 21 and the body 10 of the pusher relative to the head 16 of the pusher rod 15 is determined to so that it is equal to or greater than the active stroke y of the pusher to perform its function but also equal to or less than the distance z separating the lower shoulder 4 of the tube 1 of the pusher of the lower side wall of the groove 5 receiving the joint (s) 6. In this way these joints 6 are always in active position ensuring sealing at least 10 bar operating about.
  • the upper part of the body 10, necessarily open for mounting the push pin 15, could be closed by a screw cap or any other closure member in place of the cap 21.
