Definitions

  • the present invention relates to a push button and an assembly process making it simpler and more economical its realization and its assembly, in particular in a watch case, also making it waterproof the assembly thus produced.
  • the usual method of assembling a pusher which allows a simple press to change the state a mechanical or electronic device of a part watchmaking, involves engaging the push rod from the outside of the box, then screw on its end, from inside the box, an element stop to prevent extraction of the rod and limit the stroke of a return spring.
  • the seal between the push rod and the passage to through the box is provided by one or more seals independent of the pusher device as such.
  • the stop element is formed by a flange positioned around the rod by crimping.
  • the stop element comes from material with the stem whose inner end has a slit providing sufficient elasticity to allow a snap against the internal face of the box.
  • Other latching methods are also proposed using either the elasticity of a collar carried by the rod, as described in the patent CH 610 467, or on the contrary to the elasticity of the neck of the hole opening in the box and allowing the passage in force of the stop element as described in the patent CH 675 811.
  • the watertightness of the watch at the push rod level is provided by a joint that is not directly held or compressed by the stop element and therefore requires an arrangement particular of the rod or of the head of the pusher.
  • the guidance of the rod is not always guaranteed to satisfactorily, especially in devices by snap-in.
  • the invention therefore aims to remedy the disadvantages of previously pusher devices known by providing a building push button simple and easy to assemble.
  • the invention relates to a button pusher for a timepiece comprising a rod, provided with an operating head and sliding in a hole cylindrical formed in the middle of said piece of watchmaking, and a stop means preventing extraction of said rod, characterized in that the rod comprises side of the head an extended cylindrical main body by a tigeron separated from it by a groove intended to receive a seal said tigeron having at its end a annular clearance forming an axial tenon terminated by a annular rim, and in that the stop means comprises a socket fitted between the wall of the hole and the tigeron, of length substantially equal to the tiger, partially closed by a ring with an outside diameter greater than that of the hole and opening substantially equal to diameter of the post, said socket compressing the joint toric and being made integral with the tigeron by riveting of the annular rim of the post of the rod against the ring of the socket.
  • the means for recalling the push button are by example constituted by a spring arranged between a annular recess of the middle or the case and the inner part of the push button head.
  • the push button head can be a part reported on the stem, but also come from material with said rod.
  • the socket held by riveting at the end of the rod therefore allows both to prevent accidental tearing of the push button and exercising controlled compression on the joint to ensure perfect seal.
  • controlling the pressure on the O-ring can be adjusted during assembly in providing one or more on the internal surface of the socket several grooves complementary to annular lips arranged on the tigeron.
  • a case middle 3 of a watch case includes essentially two parts: a rod 10 of revolution around an axis XX, provided on the outside of the middle part 3 an operating head 5, and a socket 20 fixed to the other end of said rod 10, an O-ring 30 being compressed between the two parts to ensure the seal against the wall of the cylindrical hole 2.
  • the rod 10 comprises a main body 11 likewise diameter than hole 2 and a tigeron 13 extending the main body 11 and separated from it by a groove 12 in which the O-ring 30 is partially housed, the distal part of said tigeron 13 comprising a annular clearance 16 forming an axial post 17 of which the end has an annular rim 18.
  • the socket 20, made in one piece consists of of a tubular part 21 having a thickness that is substantially equal to the free space between the internal surface of hole 2 and the outer surface of the tiger 13 and a length substantially equal to that of said tigeron.
  • This part tubular 21 is partially closed at one end by a ring 22 having a thickness substantially the length total of the tenon 17 and the rim 18, an outside diameter greater than that of the hole 2 for passage of the rod, and a opening substantially equal to the diameter of the post 17, said opening being flared outward in the illustrated embodiment.
  • a return spring 6 is positioned in a groove 4 of the middle part
  • the O-ring 30 is placed in the groove 12, it is put in place from outside the middle part the rod 10 and the head 5, possibly preassembled if these elements have not been produced in one piece
  • the socket 20 is fitted from the inside of the box onto the tigeron 13, and then the riveting of the rim 18 on the outer face of the ring 22, which will cause the compression of the O-ring 30 by the end of the tubular part 21 of said sleeve.
  • the stroke of the sleeve 20 and its positioning before riveting can be adjusted, by providing in the internal surface of the sleeve 20 a groove 25 into which a lip 14 carried is snapped by the tigeron 13.
  • a button has been represented. push button which acts indirectly on an order electronic via push button intermediate 8 housed in container 9 of the movement.
  • the skilled person can obviously design other mechanical or electronic control arrangements without depart from the present invention which relates first place the construction of a push button and its process assembly in a watch case.
