Definitions

  • the invention relates to a watch strap with an optical effect.
  • the invention also relates to a method for producing a watch strap with an optical effect.
  • watch straps are made of leather, synthetic material, fabric, rubbery material, or metal.
  • the bracelets also include an insert disposed in a lining or a sheath or between an upper band and a lower band subsequently joined together. This insert has a mainly mechanical and flexible function.
  • an insert made of mechanically resistant rigid material In the case of a rubber strap, it is common to use an insert made of mechanically resistant rigid material.
  • This insert can in particular be produced via injection using a thermoplastic material of the polyamide type alone or filled (carbon fibers, glass fibers, etc.). Once the insert has been made, it is placed in the mold and the rest of the strand made of rubber is overmolded (by injection or compression) around it.
  • the bracelet includes a material pocket transparent plastic filled with a liquid and particles, the pocket housing between a lower part and an upper part of the bracelet and being visible through an opening in the upper part.
  • a material pocket transparent plastic filled with a liquid and particles the pocket housing between a lower part and an upper part of the bracelet and being visible through an opening in the upper part.
  • it does not provide sufficient protection of the pocket against environmental conditions and shock or abrasion, which constitutes a disadvantage.
  • the general thickness of such a bracelet is often too great and the pocket remains visible, which also harms the aesthetics of the bracelet.
  • the invention aims in particular to overcome the various disadvantages of bracelets of the prior art.
  • an objective of the invention is to provide a strand of bracelet with an optical effect having a controlled thickness while guaranteeing good protection of the optical effect.
  • the invention relates to a strand of bracelet made of elastomeric material, comprising a first end capable of connecting with a watch case, characterized in that it comprises a rigid insert having a solid part forming a reinforcement, and a hollow part arranged to receive a fluid and solid elements dispersed in the fluid, said hollow part being located in the center of the solid part, and in that the insert is coated in a transparent elastomer forming the bracelet strand, said insert being positioned at the first end suitable for connection with a watch case.
  • the watch strap strand 1 has a first end 10 able to receive an attachment bar and to be attached to a watch case by means of this attachment bar.
  • the bracelet strand 1 is pierced with holes 11 succeeding one another over part of its length, each of the holes 11 being provided for the passage of a member of a buckle or a pin making it possible to attach the watch strap strand 1 to the other strand of watch strap and thus close the watch strap, for example around a wrist.
  • the watch strap strand 1 is in the form of a flexible strip of elastomeric material and comprises an insert 2 on which the strip of flexible material is overmolded.
  • the elastomer forming the bracelet strand is elastically compressible and does not lend itself well to attachment to the watch case, an insert 2 is therefore integrated by overmolding at the first end of the strand 1 which is intended to be connected to the watch case .
  • the first end 10 suitable for connection with a watch case comprises a rigid insert 2 forming a reinforcement and increasing the rigidity of the strand near the watch case.
  • the insert 2 comprises a solid part 20 and a hollow part 21 formed in the center of the solid part and arranged to receive a fluid 3 as well as solid elements 4 dispersed in the fluid.
  • the solid elements 4 have a density greater than the liquid in which they are located in order to allow them to flow when the bracelet strand is moved or agitated.
  • the solid elements 4 are chosen from: 2D or 3D metallic particles, phosphorescent particles, microbeads, flakes, strips, etc.
  • Fluid 3 is chosen from: water, oil, etc. and can be colorless or colored. Obviously, the fluid must be transparent or translucent in order to reveal the solid elements.
  • the insert 2 is coated in a transparent elastomer forming the bracelet strand 1 to be able to observe the hollow part receiving the fluid and the solid elements dispersed in the fluid.
  • the elastomer is intended to be transparent or translucent, and is made from crosslinked materials of the FKM type or even silicone but also from non-crosslinked materials of the elastomeric thermoplastic type such as TPE-U or TPE-S.
  • the hollow part 21 is in the form of a logo, a letter, a number or even a pattern.
  • the insert 2 is coated in an opaque elastomer forming the bracelet strand 1, the bracelet strand comprising an opening 23 or a withdrawal of material up to the insert 2 to be able to observe the hollow part receiving the fluid and the solid elements dispersed in the fluid.
  • the insert 2 presents a logo, a letter, a number or a pattern formed in positive relief housing in a corresponding opening of the bracelet strand and forming the hollow part of the insert.
  • This insert 2 is made of a non-compressible material such as a thermoplastic.
  • the insert 2 is in the form of a parallelepiped element. The insert thus makes it possible to make the end in connection with the watch case extremely rigid.
  • the insert is made from a transparent, amorphous or very low crystallinity polymer of the type PEF, PET, polycarbonate, polyamide or even polymethyl methacrylate, epoxy or PUR.
  • the insert is made via molding, 3D printing or even machining.
  • the insert has mechanical resistance with a Young's modulus greater than 1GPa in order to be able to withstand the traction/torsion/flexion stresses of the bracelet during its installation and use.
  • the insert is reinforced with a metal blade 5 at the first end of the strand 1 which is intended to be connected to the watch case in order to ensure good tensile and traction resistance/ twisting of the bracelet, the metal blade 5 being arranged to be in contact with the watch case when the bracelet strand is attached to the latter.
  • the latter comprises a channel 22 opening onto the hollow part to fill the latter, the fluid and solid element mixture being injected into the hollow part by means of a syringe for example .
  • connection between the bracelet strand 1 and the insert 2 can be improved by an adhesion agent or mechanical adhesion elements, and thus avoid detachment of the insert during overmolding and repeated bending of the bracelet strand when used.
  • adhesion agents can be used depending on the pair of materials used.
  • the insert is in the form of two shells arranged to be assembled by means of a joint, welding or glue, each shell comprising a cavity forming the hollow part.
  • the invention also relates to a method of manufacturing a bracelet strand provided with an insert.
  • the invention also relates to a watch comprising at least one strand of bracelet conforming to the invention.
