Description

  The present invention relates to a snap fastener that is attached to, for example, a cloth of clothing.

  A conventional snap fastener is made of metal. Metal snap fasteners are generally better in appearance than synthetic resin snap fasteners.

  However, metal snap fasteners are more expensive than those made of synthetic resin, and burrs that can damage human skin may be formed during the manufacturing process. In addition, when the fabric with the metal snap fastener attached is heated, for example, during damage processing, the chlorine and sulfur contained in the fabric react with the nickel used to paint the metal snap fastener. Therefore, it has been known that the nickel sulfide may cause darkening, and this nickel sulfide is particularly likely to accumulate in the lining.

  The present invention has been made in consideration of the above-mentioned matters. The purpose of the present invention is to provide a good appearance of a metal snap fastener, but it is difficult to form a burr that can hurt human skin, and blackening in the lining also occurs. It is to provide a difficult snap fastener.

  In order to achieve the above object, a snap fastener according to the present invention comprises a synthetic resin rivet member disposed on one side of a sheet-like member and a synthetic resin fitting member disposed on the other side. The rivet member has a rivet substrate and a sharp protrusion integrally formed at the center of the back surface of the rivet substrate facing the sheet-like member, and the fitting member inserts the protrusion. A fitting substrate having a through hole formed in a central portion thereof, and a male or female fitting portion integrally formed on a surface of the fitting substrate that faces in a direction away from the sheet-like member. The protrusion of the rivet member driven from one side of the sheet-like member is inserted into the through hole of the fitting member arranged on the other side of the sheet-like member, and the tip of the protrusion is hit Expanded by The snap fastener is configured to attach the fitting member to the sheet-like member by being deformed, and includes a metal winding member that covers at least a portion extending from a peripheral portion of the rear surface to a peripheral portion of the surface of the rivet substrate. (Claim 1).

  The said snap fastener WHEREIN: The opening for exposing the surface of the said rivet board | substrate may be provided in the site | part which covers the surface of the said rivet board | substrate in the said winding member.

  According to the present invention, it is possible to obtain a snap fastener that has a good appearance of a metal snap fastener, hardly forms a burr that can damage human skin, and hardly causes darkening in the lining.

  That is, in the snap fastener of the device according to each claim of the present application, the appearance of clothes and the like to which the snap fastener is attached can be improved by the metal winding member.

  In addition, the snap fastener of the present invention is not made entirely of metal, but only the winding member is made of metal and the other members are made of synthetic resin.

  Furthermore, in the case of a metal snap fastener, a burr that can damage human skin may be formed in the manufacturing process, but in the snap fastener of the present invention, only the winding member is attached to the rivet substrate, Such burr formation is unlikely to occur.

  Further, in the snap fastener of the present invention, only the winding member wound around the rivet member appearing on the surface side is made of metal, so that blackening due to the influence of nickel sulfide that easily collects on the lining hardly occurs.

  In the snap fastener according to the second aspect of the present invention, it is possible to give a unique design by exposing the rivet substrate from the opening of the winding member.

It is a longitudinal cross-sectional view which shows schematically the structure of the said snap fastener of the state fastened. (A) And (B) is the longitudinal cross-sectional view and perspective view which show the structure of the principal part of the said snap fastener roughly. It is a longitudinal cross-sectional view which shows schematically the structure of the principal part of the snap fastener which concerns on the modification of this invention.

  Embodiments of the present invention will be described below with reference to the drawings.

  The snap fastener shown in FIGS. 1 and 2 includes a female snap fastener 1 and a male snap fastener 2.

  Among them, the female snap fastener 1 is a synthetic resin rivet member 4 disposed on one side of a sheet-like member 3 such as a cloth of clothing and a synthetic resin female fitting fitted on the other side. A combination member (socket) 5 is provided.

  The rivet member 4 has a rivet substrate (disk-shaped head) 6 and a sharp protrusion 7 integrally formed at the center of the back surface of the rivet substrate 6 facing the sheet-like member 3. The member 3 can be pierced.

  The female-type fitting member 5 has a fitting substrate 9 in which a through hole 8 for inserting the protrusion 7 is formed in the center portion, and a surface directed in a direction away from the sheet-like member 3 in the fitting substrate 9. And a female fitting portion 10 formed integrally. The female fitting portion 10 has a substantially cylindrical shape, and an engagement bulging portion 10a is formed on the inner peripheral surface on the front end side.

  In the female snap fastener 1 having such a configuration, the protrusion 7 of the rivet member 4 driven from one surface side of the sheet-like member 3 has the female fitting member 5 disposed on the other surface side of the sheet-like member 3. The female fitting member 5 is attached to the sheet-like member 3 by inserting into the through hole 8 and expanding and deforming (flanging) the tip of the projection 7 by striking (for fitting the rivet member 4 and the female die). The member 5 can be clamped).

  On the other hand, the male snap fastener 2 is for fitting a synthetic resin rivet member 12 disposed on one surface side of a sheet-like member 11 such as a cloth of clothing and a synthetic resin male mold disposed on the other surface side. A member (stud) 13 is provided.

  The rivet member 12 has a rivet substrate (disk-shaped head) 14 and a sharp protrusion 15 integrally formed at the center of the back surface of the rivet substrate 14 facing the sheet-like member 11. The member 11 is configured to be pierced.

  The male fitting member 13 has a fitting substrate 17 in which a through hole 16 for inserting the protrusion 15 is formed in the center portion, and a surface directed in a direction away from the sheet-like member 11 in the fitting substrate 17. And an integrally formed male fitting portion 18. The male fitting portion 18 has a substantially cylindrical shape, and an engagement bulging portion 18a is formed on the outer peripheral surface on the distal end side.

  In the male snap fastener 2 having such a configuration, the protrusion 15 of the rivet member 12 driven from one surface side of the sheet-like member 11 has the male fitting member 13 disposed on the other surface side of the sheet-like member 11. The male fitting member 13 is attached to the sheet-like member 11 by inserting into the through hole 16 and expanding and deforming (flanging) the tip of the protrusion 15 by striking (for fitting the rivet member 12 and the male die). The member 13 can be clamped).

  Here, the rivet member 4 and the female fitting member 5 of the female snap fastener 1 and the rivet member 12 and the male fitting member 13 of the male snap fastener 2 are both polyacetal and nylon. It can be formed of synthetic resin such as polyester (mixture of unsaturated alkyd and vinyl monomer), polyamide resin, etc., and is preferably formed of synthetic resin having high heat resistance.

  Then, of the rivet members 4 and 12, with the snap fasteners fastened (as shown in FIG. 2, the male and female snap fasteners 1 and 2 are elastically fitted), for example, overlaps with clothes. The rivet member (head) 4 that appears on the surface side of the edge (for example, the upper placket) is wound with a metal winding member 19 that covers at least a portion of the rivet substrate 6 extending from the periphery of the back surface to the periphery of the surface. Yes.

  As shown in FIGS. 3A and 3B, the winding member 19 of the present embodiment covers only the bulging portion 6a at the periphery of the rivet substrate 6 that bulges to the back surface side on the back surface side of the rivet substrate 6. The rivet substrate 6 is configured so as to cover the entire surface thereof on the surface side of the rivet substrate 6. Further, the winding member 19 may be formed of any one of brass, iron, copper, aluminum, and white.

  Thus, in the snap fastener of this embodiment in which the metal winding member 19 is attached to the rivet member 4 that appears on the surface side in a state where the snap fastener is fastened, the appearance of clothes or the like to which the snap fastener is attached is improved. be able to.

  Further, in this embodiment, the entire snap fastener is not made of metal, but only the winding member 19 is made of metal and the other members are made of synthetic resin. .

  Furthermore, in the case of a metal snap fastener, a burr that can damage human skin may be formed in the manufacturing process, but in this embodiment, the winding member 19 is only wound around the rivet substrate 6, Such burr formation is unlikely to occur. Further, by avoiding the winding member 19 from being wound around the rivet member 12 located on the back side of the rivet members 4 and 12, there is a possibility that the snap fastener hits the wearer's skin. There are only parts made of synthetic resin, and high safety can be obtained.

  When the fabric with the metal snap fastener attached is heated, for example, during damage processing, the chlorine and sulfur contained in the fabric react with the nickel used to paint the metal snap fastener, There is a risk of changing to nickel sulfide, which causes darkening, and it has been found that this nickel sulfide is particularly likely to accumulate in the backing. However, in this embodiment, since only the winding member 19 wound around the rivet member 4 that appears on the front side is made of metal, darkening due to the influence of nickel sulfide that easily collects on the backing is less likely to occur.

  It should be noted that the present invention is not limited to the above-described embodiment, and can be variously modified and implemented without departing from the gist of the present invention. For example, the following modifications can be given.

  In the example shown in FIGS. 2 and 3, the winding member 19 covers the entire surface of the rivet substrate 6. However, the present invention is not limited to this. For example, as shown in FIG. You may provide the opening 20 for exposing the center part of the surface of the rivet board | substrate 6. FIG. In this case, it is possible to have a unique design by exposing the rivet substrate 6 from the opening 20 of the winding member 19. Note that the opening 20 shown in FIG. 4 is, for example, circular, but may have other shapes, and a plurality of openings 20 may be provided instead of only one. However, the peripheral edge may be exposed through the opening 20. In addition, also on the back surface side of the rivet substrate 6, the winding member 19 may cover not only the bulging portion 6 a at the periphery of the rivet substrate 6 but also an inner portion.

  In the above embodiment, since the female-type snap fastener 1 and 2 appear on the surface side of the female-type and male-type snap fasteners 1 and 2, the winding member is wound around the rivet member 4 of the female-type snap fastener 1. In contrast, when the male snap fastener 2 appears on the surface side, the winding member 19 may be attached to the rivet member 12.

  Needless to say, the modifications shown in this specification may be combined as appropriate.
