Definitions

  • the present invention relates to button attachments, in particular, button attachments for attaching snap buttons, tack buttons, buttons of the type that can be taken in and out of button holes, etc. to clothes or bag fabrics.
  • the fixture main body includes a tubular portion and a flange portion extending radially outward from one end in the axial direction of the tubular portion.
  • the fixture main body includes a tubular portion and a flange portion extending radially outward from one end in the axial direction of the tubular portion.
  • the fixture body is connected to the cap by crimping the protruding end side portion of the annular protrusion with respect to the radial outer portion of the flange portion so as to plastically deform inward in the radial direction.
  • the cylinder part of the attachment body of the button attachment is passed through from the back side to the front side of the cloth, and then the other end side in the axial direction of the cylinder part (the side opposite to the flange part). This is done by crimping the part against the button.
  • the surface of the cap of the button attachment attached to clothes or the like together with the button is visible to the user on the back side of the clothes or the like. Therefore, a logo, characters, or the like may be attached to the surface of the cap.
  • the connection of the cap to the attachment body may be weakened over time, and the cap may rotate with respect to the attachment body. In this case, the logo or characters on the surface of the cap are turned upside down, and the uniformity of the design is impaired. Further, the rotation of the cap with respect to the fixture body may separate the fixture body from the cap, or the button may easily come off from the fabric.
  • an object of the present invention is to provide a button attachment that can eliminate or reduce the rotation of the cap with respect to the attachment body.
  • the attachment is a button attachment including a metal attachment body and a synthetic resin cap to which the attachment body is connected.
  • the tool body includes a tubular portion and a flange portion extending radially outward from one end in the axial direction of the tubular portion, and the flange portion includes a plurality of notches recessed inward in the radial direction from the peripheral edge of the flange portion.
  • the cap is provided with a button attachment comprising a crimping portion of the flange portion that has been crimped to a radial outer portion including the plurality of notches.
  • the flange portion of the fixture body is provided with a plurality of notches recessed inward in the radial direction from the peripheral edge thereof.
  • the crimping portion of the cap is crimped to the radial outer portion of the flange portion including the plurality of notches, so that the crimping portion applies the radial outer portion of the flange portion to the back surface of the cap.
  • the resin material of the crimping portion enters each notch so as to fill each notch. This makes it possible to eliminate or reduce the rotation of the cap with respect to the fixture body.
  • examples of the metal forming the fixture body include aluminum, aluminum alloy, copper, copper alloy, nickel, nickel alloy, zinc, zinc alloy, iron, stainless steel and the like, but are limited thereto. It's not a thing.
  • examples of the synthetic resin forming the cap include, but are not limited to, thermoplastic resins such as polyacetal, polyamide, polypropylene, and polybutylene terephthalate.
  • the plurality of notches are formed at the predetermined angular intervals. For example, when there are three notches, the notches are formed at intervals of 120 degrees in the circumferential direction of the flange, and when there are five notches, the notches are formed at intervals of 72 degrees in the circumferential direction of the flange.
  • each of the notches intersects the peripheral edge of the flange at an obtuse angle.
  • Each notch is a portion obtained by removing a part of the flange so as to be recessed inward in the radial direction from the peripheral edge of the flange, and one notch intersects the peripheral edge of the flange at two points.
  • the cap includes an annular ridge portion on the back surface of the fixture body facing the flange portion, which defines an accommodating portion for receiving the flange portion in the radial direction, and the crimping portion. Extends inward in the radial direction from the annular ridge, and the cap is located at the ridge-side end of the annular ridge on the opposite side of the crimping portion to the inside facing the radial outer portion of the flange. On the other hand, it includes an annular micro-recess that is recessed on the back surface side.
  • the flange portion of the fixture body is arranged in the accommodating portion which is the space inside the annular ridge on the back surface of the cap in the radial direction.
  • the crimping portion which was originally an extension portion on the raised side of the annular raised portion, is crimped to the radial outer portion of the flange portion.
  • the radial outer portion of the flange portion is sandwiched between the back surface of the cap and the crimping portion, and is connected to the fixture body and the cap.
  • the crimping part is crimped by heat crimping with heating, but by crimping the crimping part by cold working without heating, the manufacturing cost including electricity cost can be further reduced. ..
  • cold working a sufficient amount of resin can be penetrated into the notch of the flange portion, and a minute recess is generated at the time of crimping. It can be seen that due to the presence of the minute recesses, the crimping portion firmly sandwiches the radial outer portion of the flange portion with the back surface of the cap.
  • the cap includes a central raised portion that is raised in the center of the back surface.
  • the central raised portion allows the base end side of the tubular portion of the fixture body to be supported when the tubular portion is crimped.
  • the button is fixed to the fabric together with the button attachment by penetrating the cylinder of the attachment body through the fabric and then tightening the cylinder against the button.
  • the central raised portion can support the base end side of the tubular portion, that is, the curved portion of the fixture body, which will be described later, thereby preventing buckling of the tubular portion.
  • the cap when the cylinder is crimped when attaching the button to the fabric, the cap receives the crimping load, so dents remain on the surface of the cap opposite to the back surface, and the logo on the front surface is crushed. Defects can occur.
  • the central portion of the cap is thickened by the central raised portion provided in the center of the back surface of the cap, and a part of the crimping load acting on the cap when the tubular portion is crimped is a thick central raised portion. By receiving it, it is possible to avoid or reduce the above-mentioned defects.
  • the base end side of the tubular portion includes the vicinity of the tubular portion in the flange portion.
  • the fixture body includes a curved portion that connects the tubular portion and the flange portion in a curved shape, and the central raised portion is raised to the end of the curved portion on the tubular portion side. ..

  • the thickness of the central raised portion in the axial direction that is, the height from the back surface of the cap is extended to the end of the curved portion of the fixture body on the tubular portion side, so that the load is the largest when the tubular portion is crimped.
  • the curved portion of the fixture body can be reliably supported by the central raised portion, which can prevent buckling of the tubular portion and the like.
  • the flange portion of the fixture body is provided with a plurality of notches recessed inward in the radial direction from the peripheral edge thereof.
  • the crimping portion of the cap is crimped to the radial outer portion of the flange portion including the plurality of notches, so that the crimping portion applies the radial outer portion of the flange portion to the back surface of the cap.
  • the resin material of the crimping portion enters each notch so as to fill each notch. This makes it possible to eliminate or reduce the rotation of the cap with respect to the fixture body.
