Definitions

  • the subject of the invention is a spiral spring for horological instrument for measuring time.
  • spiral springs usually used in watches are made up of several parts, which must be carried out with great precision, then assembled, to form a part composite.
  • the complexity of manufacturing a such a part involves high costs and complex settings.
  • the purpose of the present invention is to provide a spiral spring with a cost price as low as possible and with no defect if possible Operating.
  • the spiral spring according to the invention is characterized in that it is made in one molecularly discontinuous piece with its ferrule.
  • spiral spring according to the invention With the spiral spring according to the invention, it has been produced a high quality piece and perfectly balanced. The fact that it was made in a single piece without discontinuity avoids defects inherent in conventional manufacturing notably internal tensions of matter and defects in the precision of the assembly of constituent parts. On the other hand the price of returns from the spiral spring according to the invention and considerably decreased compared to the spring of prior art.
  • the manufacture of the spiral spring according to the invention can advantageously be carried out using known techniques, in particular by operations micro-molding, by molding with molds made by illumination of resins sensitive to UV rays, by deposit treatments galvanic with or without mold, by projection of material or by conventional cutting in particular by laser, wire EDM or EDM diving, stamping or cutting material plate by jet of liquid under high pressure.
  • the spiral spring may have a piton also made in one piece without molecular discontinuity with its curve terminal.
  • the piton can be in the form of a circular cylinder of the same height as the spiral spring leaf.
  • Piton can appear in the form of an enlarged part with respect to the blade offering a certain elasticity allowing it to be introduced by friction into a cavity and the enlarged part can be realized in the form of two circular branches elastic.
  • the peg can be introduced by friction into a bore of a support, the bolt being blocked in releasing its elastic tension in a bore perpendicular or axially crossing the bore practiced in the support.
  • the ferrule has a slot and two openings allowing static balancing of the part as well as taking it with a tool mounting.
  • the ferrule may also have at its periphery tracking notches.
  • the end made in one piece with the terminal curve may have one or more notches engaged with the thread of a screw, the screw being retained axially in the support and a plug housed in the support allows to serve as attachment point to hairspring.
  • spiral spring can be produced by micro-molding techniques, by molding with molds made by illumination of resins sensitive to UV rays, by galvanic deposits with or without mold, by material projection or by cutting conventional including laser, EDM wire or EDM, stamping or by cutting a material plate by jet of liquid under high pressure.
  • the spiral spring shown in fig. 1 comprises a blade 11 having in its center a ferrule 12 and at its outer end, a terminal curve 13.
  • Micro-molding technique consisting of depositing a metal inside a mold by a process galvanic.
  • the ferrule 12 is presented as shown in the fig. 1 in the form of a wide circular ring dimension and has a slot 14 allowing it to be chased on an axis without splitting and without veil during assembly.
  • a piton 15 of circular shape made in one piece without molecular discontinuity with the hairspring and its ferrule; of course the shape of the pin 15 is not limited to a circular configuration and said piton can be made in any desired form, for example in circular form with a slit as it is the case in traditional watchmaking or another suitable geometric shape and a hole can be done in the center of the apple the end to facilitate its fixing.
  • the pin 15 of fig. 2 is shown in perspective and enlarged scale in fig. 3.
  • Fig. 4 a variant of the pin 15, which includes two circular branches 16 and 17 having a certain elasticity.
  • the piton of fig.4 may, given its character elastic, be introduced by friction into a bore 18 of a movable piton holder 19 or of a plate 19 of the timepiece.
  • Exhibit 19 has a perpendicular bore 20 in which will block the piton 15 of the execution mode in fig. 4, after branches 16 and 17 have returned to their original positions.
  • the ferrule 12 shown in fig. 6 with its slot 14 includes two openings 21 and 22 serving on the one hand to balance statically the assembly consisting of blade 11, of the ferrule and depending on the case, the terminal curve 13 and serves on the other hand to facilitate handling and gripping the part using a tool.
  • a number notches are used to distinguish the type of spring spiral.
  • three are represented notches 23; however, the shape and number notches can be chosen as required.
  • fig. 8 we find a spiral spring 30 similar to that of the modes of previous execution. With its ferrule 12, its slot 14 and its terminal curve 13.
  • the piton is presented here in the form of a enlarged end 31 made without discontinuity molecular with the terminal curve 13.
  • the end 31 has notches 32 in engagement with the thread of a screw 33 retained by means of two pins 34 inside a bore 35 of a support 36.
  • the part opposite the teeth 32 of the end 31 has a smooth surface 37 allowing the end 31 of sliding against a surface 38 of the support 36 under the action of rotation of the screw 33.
  • the rotation of the screw 33 therefore makes it possible to adjust end position 31 in order to do vary the active length of the terminal curve 13.
  • a plastic or metallic plug 39 allows to maintain in friction laterally the attachment point of hairspring 40.
