Definitions

  • This invention relates to an ornamental button, such as a male-female button to be used on a garment or a tack button to be used on a garment of denim, and more particularly to an ornamental button body assembly and a method for manufacturing the same.
  • An ornamental button body assembly is currently known (from Japanese Patent Publication No. HEI 1-37122) which comprises an ornamental button body made of hard plastics,and having in its rear surface a recess with a groove extending along the deepest portion of its peripheral wall, and a metallic clasp in the form of a tube having at its base a ridged flange adapted to be deformed to expand outwardly; in assembling, the flange is inserted into the recess and is then compressed and expanded by a tool so as to be fitted in the groove.

  • FIG. 1 Japanese Utility Model Laid-Open Publication No. HEI 2-130214
  • DE-A-1 936 163, on which the preamble of claim 1 is based discloses an ornamental button body assembly comprising an ornamental button body and a tubular clasp; said ornamental button body having a recess in a rear surface of said ornamental button body; said recess having a bottom, an inside wall and a mouth with an edge; said tubular clasp having at one end a flange substantially equal in diameter to said edge of said mouth of said recess, said flange being received in said recess.
  • an ornamental button body assembly comprising an ornamental button body and a tubular clasp; said ornamental button body having a recess in a rear surface of said ornamental button body; said recess having a bottom, an inside wall and a mouth with an edge; said tubular clasp having at one end a flange substantially equal in diameter to said edge of said mouth of said recess, said flange being received in said recess; characterised in that said bottom of said recess is larger in diameter than said edge of said mouth of said recess; and in that the ornamental button body assembly further comprises an annular spring disposed between said flange and said inside wall of said mouth of said recess.
  • the recess may have an inverted frustoconical contour, the flange of the clasp being bent along an outer peripheral edge so as to form a complement to the sloping inside wall of the frustoconical recess.
  • an ornamental button body assembly comprising the steps of: inserting a flange of a tubular clasp into a recess formed in a rear surface of an ornamental button body with a bottom larger in diameter than a mouth, the flange being substantailly equal in diameter to a mouth edge of the recess; forcibly inserting an annular spring between a surface of the flange and the inside wall of the mouth of the recess while compressing the annular spring; and then restoring the compressed annular spring.
  • a tubular clasp having at one end a flange is placed in the recess formed in the rear surface of the ornamental button body, with an annular spring sandwiched between the inside wall of the recess and the front surface of the flange, so that the tubular clasp is attached to the ornamental button body stably, thus making the ornamental button body assembly durable in any use.
  • this ornamental button body assembly When this ornamental button body assembly is used in an ornamental button such as a female button, a male button or a tack button, the tubular portion projecting from the rear surface of the ornamental button body is pierced through, for example, a piece of cloth and then the distal end of the tubular portion is clenched against a female body, or the clasp having a U-shape tubular portion is placed on one surface of a piece of cloth and then the tack is pieced through the cloth from the other surface so as to be secured to the tubular clasp.
  • an ornamental button body assembly includes an ornamental button body 1 for an ornamental button, such as a female-male button or a tack button, formed of hard plastics, bone, ivory or metal.
  • the ornamental button body 1 has a recess 2 which is formed centrally in a rear surface of the ornamental button body 1 and which has a frustoconical inside wall 3 increasing in diameter progressively from the mouth to the bottom in such a manner that the area of the bottom of the recess 2 is slightly larger than that of the mouth.
  • the ornamental button body assembly also includes a tubular clasp 5 having at one end a flange 4 which is substantially equal in diameter to a mouth edge 10 of the recess 2 and which is inserted in the recess 2.
  • An annular spring 6 having a circular cross section and a cutout is inserted between the flange 4 and the inside wall 3 of the mouth of the recess 2. The annular spring 6 serves to hold the flange 4 of the tubular clasp 5 stably in the recess 2, preventing the flange 4 from being removed from the recess 2.
  • the annular spring 6 used in this embodiment should by no means be limited to a cutout-ring spring and may be a disk spring or a rubber spring, if it is a resilient member shrinkable and extendible radially within a constant circle.
  • the tubular clasp 5 may be a clasp having a tubular portion whose distal end is folded into a U shape, as shown in FIG. 6.
  • reference numeral 7 designates a female button body; and 8, a piece of cloth through which the tubular portion of the clasp 5 attached to the rear surface of the ornamental button body 1 is pierced, whereupon the distal end of the tubular portion is clenched against the tubular portion of the female button body 7 to thereby attach the female button body 7 to the cloth 8.
  • the shape of a recess 2 formed centrally in the rear surface of an ornamental button body 1 is totally identical with that of the first embodiment.
  • the shape of an outer peripheral edge 9 of a flange 4 of a tubular clasp 5 is different from that of the previous embodiment, being bent so as to complement to the slant inside wall 3 of the inverted frustoconical recess 2.
  • a cutout annular spring 6 is inserted between the bent outer peripheral edge 9 of the flange 4 and the inside wall 3 of the mouth of the recess 2.
  • a recess 2 formed in the rear surface of an ornamental button body 1 is similar to that of the previous embodiment except that the mouth edge 10′ of the recess is rounded to facilitate insertion of an annular spring 6.
  • the annular spring 6 has a generally triangular cross section.
  • a recess formed in the rear surface of an ornamental button body with a bottom larger in diameter than a mouth is different from the inverted frustoconical shape of the foregoing embodiments and has a mere peripheral groove.
  • the rounded mouth edge 10′ of the recess 2 is rounded to facilitate insertion of an annular spring 6.
  • the annular spring 6 has a trapezoidal cross section; for insertion, the annular spring 6 is forced into the recess 2 with its slant surface facing the rounded mouth edge 10′ of the recess 2 of ornamental button body 1, with its apex contacting a flange 4 of a tubular clasp 5 and with its bottom surface facing the inside wall 3 of the mouth of the recess 2. Therefore the annular spring 6 can be inserted in a simple operation and serves to secure the tubular clasp 5 to the ornamental button body 1 stably.
  • an ornamental button body assembly comprising the steps of: inserting the flange 4 of the tubular clasp 5 into the recess 2 formed centrally in the rear surface of the ornamental button body 1 with the bottom larger in diameter than the mouth, the flange 4 being substantailly equal in diameter to the mouth edge of the recess 2; forcibly inserting the annular spring 6 between the front surface of the flange 4 and the inside wall 3 of the mouth of the recess 2 while compressing the annular spring 6; and then restoring the compressed annular spring 6 to secure the tubular clasp 5 to the ornamental button body 1.
  • the apparatus comprises an ornamental button body holding die 11, an auxiliary die 12 and a punch 13.
  • the holding die 11 has a flat upper surface for supporting an ornamental button body 1.
  • the auxiliary die 12 is to be mounted on the upper surface of the holding die 11 and has vertically extending and axially aligned upper and lower through-holes 15, 14.
  • the diameter of the upper through-hole 15 is equal not only to the outside diameter of the flange 4 of the tubular clasp 5 but also to the diameter of the edge of the recess 2 of the ornamental button body 1.
  • the diameter of the lower through-hole 14 is equal to the outside diameter of the ornamental button body 1.
  • the mouth edge 16 of the upper through-hole 15 is tapered to support the annular spring 6 for compression.
  • the punch 13 has a diameter equal to the diameter of the upper through-hole 15 of the auxiliary die 12 and is reciprocatingly movable into and out of the upper through-hole 15, having an axial hollow 17 large enough to receive the tubular portion of the clasp 5.
  • the ornamental button body 1 with its front surface facing downwardly is placed on the holding die 11, and then the flange 4 of the tubular clasp 5 is inserted into the recess 2 of the ornamental button body 1, whereupon the auxiliary die 12 is positioned above the ornamental button body 1.
  • the ornamental button body 1 is placed in the lower through-hole 14 and then the annular spring 6 is placed on the tapered mouth edge 16 of the upper through-hole 15.
  • the punch 13 is lowered to compress the annular spring 6 and then to insert the compressed annular spring 6 into the recess of the ornamental button body 1, whereupon the compressing action is released to restore and hence expand the annular spring 6 to secure the tubular clasp 5 to the ornamental button body 1.
