Definitions

  • the present invention relates to a closure element, more particularly intended to be attached to a garment and which cooperates with another device of closing.
  • the present invention also relates to a closure device, formed from two closure elements, and to bring together and join reversibly two different parts of a garment.
  • the present invention and a method of manufacturing a closure member.
  • a user wants to continually bring together and join two parties different from a garment, an undergarment, a piece of clothing for sport, leather goods, etc., to facilitate donning and / or use. From a functional point of view, and in the field of clothing, such a closure temporary and reversible is done, the most commonly and since many years, using fibulae, buttoning, stapling, snapping, lacing or by mutual gripping of two surfaces.
  • article comprising a closure device operated by two magnets.
  • a first closure element is attached to the free end of the first strap and a second closure member is attached to the free end of the second strap.
  • the two elements each comprise a body made of a polymeric material and a magnet encased in a hollow in the body.
  • the magnet of the first element has a directly accessible face directly in contact with a face directly accessible from the magnet of the second element.
  • magnets coming from each other are directly accessible and / or have a face directly apparent.
  • the contact with the air is going to promote corrosion phenomena on the surface of magnets.
  • These degradations are further amplified due to shocks and slips of the two magnets on top of each other.
  • magnets are subject to surface treatments, for example by depositing a layer of nickel or zinc.
  • these coatings protection will eventually wear out and disappear as the friction mechanical.
  • these magnets can be easily torn off and lost, either because of their direct attachment to tissue, either because of their insertion in a hollow. Indeed, the method of fixing these magnets is insufficient to withstand the tensile forces acting perpendicular to their respective surface when opening of the device.
  • EP-0,923,887 a device for closure for bags or clothing.
  • the closure device comprises two elements coming to cooperate with each other.
  • Each of the elements includes a body with a dwelling, inside which is placed a magnet.
  • the body also includes a means of fastening the element to the garment.
  • a contact surface of the body is plate against a mating contact surface of the second closure member.
  • the magnet is visible at inside the body. But, no method of realization is described for the arrangement of this magnet inside its housing. It seems that the magnet is arranged in the mold before an injection of the polymeric material.
  • the body is made in a metallic material made of a Zn-Al-Mg alloy, of a type known as Zamac.
  • the magnet is disposed in an insert which is then introduced by crimping into an open housing on the side of the future contact face.
  • Zamac is a material that can not be welded, which causes a weak resistance of the magnet to traction during the successions of openings of the device. Despite the presence of the insert, the magnet is likely to come off.
  • the Zamac surfaces are varnished to resist chemical aggression, and at the end at a relatively short moment, the layer of varnish disappears.
  • the choice of colors is limit to walleye, silver, nickel-plated.
  • the weight of such a closure device metal will be more important, making it quite unusable for clothing, such a weight being totally crippling in the lingerie sector.
  • Zamak closures are reserved for high clothing of range.
  • a main problem that the invention proposes to solve is to a magnet closure, as an example for bathing suits, which is particularly resistant to all chemical attacks, for example by chlorine pools, hot water, laundry, salt water.
  • a second problem is to achieve a closure with two elements each of which magnets remains firmly and permanently attached to the element, without risk of tearing.
  • a third problem is to provide a method of manufacturing closure elements which is particularly simple to implement and effective in terms of sealing obtained.
  • the invention therefore relates to a closure element, able to be attached to a garment and cooperating with a second conjugated closure member to form a closure device for the garment.
  • the closure member comprises a body, made of a polymer material.
  • the body has a means of fixing the element from closure to the garment, a contact surface pressing against a surface of the second conjugated closure member and a housing, with an opening and an outer circumference.
  • the closure element comprises a magnet, placing inside the housing of the body, and coming to attract a conjugate magnet from second conjugate closure element.
  • the element is characterized in that it comprises a lid, located on the opposite side to the surface of contact.
  • the lid hermetically seals the opening of the housing in which is placed the magnet, covering the outer periphery of the body housing.
  • the magnet is totally enclosed in a polymeric material.
  • the two magnets attract each other through the body's polymer constituting a gap.
  • the magnet With a cover provided opposite the contact face, the magnet can not leave its housing, whatever the shocks related to the opening and closing the device over time.
  • the magnet is thus totally protected phenomena of external aggression, mechanical or chemical.
  • the seal is guaranteed by the surface of the lid in contact with the assembly surface of the body around the accommodation.
  • the present invention also encompasses a portion of ferromagnetic able to be attracted by magnetism.
  • the body can advantageously also include anti-shifting means. These means are intended to prevent a separation of the closure element with the second closure element conjugate, by traction exerting substantially in the plane of the contact surface.
  • the anti-shifting means may comprise at least one male form that can be protruding substantially perpendicularly from the contact surface.
  • the male form can engage in at least one corresponding female form of second conjugate closure element.
  • the male form (s) and females may be located on the periphery of the contact area, in order to maintain a substantially smooth and unobstructed contact surface.
  • the closure member may further comprising a wafer or shell of a non-magnetic metallic material.
  • the wafer and shell can be inserted between the cover and the magnet.
  • the plate and the shell can help to focus the magnetic field of the magnet into direction of the contact surface and to minimize the losses of this same field magnetic. Inopportune attractions, many closing elements placed next to each other different clothes are avoided in the shelves.
  • the lid can be advantageously made of a polymeric material analogous to the polymer material of the body.
  • the cover may include a exterior decoration made by pad printing or hot stamping. Or, he can be molded with different shapes. Brands or logos can be engraved in hollow or raised.
  • a closure device characterized in that it comprises two elements according to any one of preceding claims cooperating in a reversible manner with each other, for attraction of their respective magnet.
  • the two closure elements may be strictly identical.
  • the method may further comprise a step of inserting between the cover and the magnet a wafer or shell of a metallic material nonmagnetic.
  • a closure device (1) is formed from two closure elements (2 and 3) mutually attracting each other (see Figure 1).
  • the shape of the two elements of closing (2 and 3) is strictly identical.

  • the body (4) is generally cylindrical.
  • the closure device (1) is intended for a swimsuit (not shown in detail).
  • the body (4) thus presents means attaching to the free end (6) of a strap (7) of the jersey (see Figure 2).
  • These fastening means are a loop (8), here of substantially triangular shape, in outgrowth from the body (4).
  • the loop (8) is made with a central opening (9) to pass the end (6) of the strap (7) which will then be buckled on itself by a seam (11).
  • Other attachment means can be envisaged according to the piece of clothing and fabrics.
  • the inner dimension of passers-by (8) can go from 6 mm to 20 mm. There may also be, in place of passers-by (8), two holes of each side of the body (4) for sewing the latter on the garment.
  • the two elements (2 and 3) each comprise a magnet (12).
  • the magnet (12) is placed in a housing (13) formed inside the body (4).
  • the housing (13) is substantially cylindrical and has dimensions hardly slightly larger than the dimensions of the magnet (12).
  • One of the circular faces of the housing (13) is open and the other of the circular faces of the housing (13) is closed by the bottom of the housing (13) with the body (4) and its constituent material.
  • the magnet (12) is introduced into the housing (13) by the open circular face.
  • the accommodation (13) a circular outer circumference located around its open circular face.
  • the magnet (12) is substantially in the form of a flat cylinder with two surfaces circular poles.
  • the polarity of the magnets (12) is reversed between the first element (2) and the second element (3). It will be readily understood that the magnet (12) of the first element (2) will attract (Arrows A in Figure 1 and 3) the magnet (12) of the second element (3) or vice versa.
  • the dimensions of the magnet (12) are of the order of 9 mm in diameter for 1 mm thick.
  • the magnet (12) is made of a material selected from the rare earth group, for example example alloy Neodymium-Iron-Boron. These are the most advanced products that the market can offer. Neodymium-Iron-Boron, normally covered by a bath of Zinc, develops a power seven to ten times greater than magnetic materials traditional.
  • the body (4) thus has a contact surface (14).
  • the surface (14) has a substantially round shape and is flat.
  • the surface (14) lies in a plane parallel to the plane constituted by the passer (8) or is confused with this plane.
  • the surface (14), the face circular magnet (12), the circular outer periphery (15) and the bottom (16) of the magnet housing (13) are substantially parallel. This surface (14) of the first element (2) is pressed against the opposite homologous surface (14) of the second element (3).
  • the thickness of material between the bottom (16) of the housing (13) and the surface (14) constitutes the air gap of the magnet (12).
  • This gap has example a thickness of 0.4 mm, which generates a thickness of 0.8 mm between the two magnets (12).
  • the body (4) is provided with a male part in the form of a notch (17).
  • the notch (17) is disposed on the edge of the surface (14) and projects from the same surface (14) in direction of the opposite surface (14) of the other element.

  • the engagement of the notches (17) in the recesses (18) thus makes it possible to avoid a slipping by sliding of the two contact surfaces (14) of each of the elements (2 and 3) one over the other. This sliding occurs when the straps (7) are subjected to traction forces acting substantially in the plane of the contact surface (14).
  • Engaging the notches (17) in the recesses (18) also makes it possible to avoid a rotation of each of the elements (2 and 3) relative to each other.

  • the cover (21) of the first element (2) can not touch neither the cover (21) nor the contact surface (14) of the second element conjugate (3).
  • the magnet (12) is thus firmly held inside the body (4) and the closure element (2 and 3).
  • the cover (21) has a different bulge. With this lid (21) remaining perfectly visible to the user and any other person, a decoration, a brand logo, an inscription (23) are realized (see Figure 6). Methods of making the inscription (23) particularly interesting are the pad printing or also the hot stamping.
  • the position of the cover (21) allows a decrease in the thickness of the gap. With the cover, the magnet (12) is completely protected from rust. With this lid (21), the magnet (12) can not be torn off.
  • the lid (21) is made of a material polymer, similar to the body material (4). The fastest method of realization preferentially chosen for the body (4) and the lid (21) is injection-molding a thermoplastic polymer. The magnet (12) must be placed in the housing (13), making sure to interchange the poles one element (2 or 3) out of two.
