In this case, the deformation of the post portion is hindered to adversely affect the connection between the button and the button stopper, or a work for removing the cloth waste after the button is attached is necessary.

Japanese Utility Model Publication No. 60-8724 JP-A-2005-204911

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a button fastener and a button structure that can securely attach a button to a cloth even if the cloth is thin. is there.

  Another object of the present invention is to provide a button stopper and a button structure in which dough debris generated when a button is attached does not adversely affect the attachment of the button, and the dough removal operation is unnecessary. It is in.

  In order to solve the above-described problems, according to the present invention, there is provided a button stopper for attaching a button to a fabric (including leather, resin sheets, etc. in addition to woven fabric, felt, nonwoven fabric, etc.). -Shaped base portion, and a fastener body including a post portion projecting concentrically with the base portion upward from the center of the base portion, and a cover member attached to the fastener body so as to cover the lower surface of the base portion The base portion includes a base bottom portion adjacent to the post portion, and a base flange portion protruding upward with respect to the base bottom portion on a radially outer side of the base bottom portion, and the cover member is formed from a lower surface side of the base portion. A button stop is provided that includes a curved outer periphery that curves and rises above a base flange portion of the base portion.

  In the present invention, when the button is attached to the fabric, the fabric is sandwiched between the button and the curved outer peripheral portion of the cover member of the button stopper. The curved outer peripheral portion of the cover member is the base portion of the fastener main body. In this case, the distance between the facing button and the curved outer peripheral part is narrow when attaching the button, so that the button can be attached to a thinner cloth. Become.

  In one embodiment of the present invention, the post portion has a hollow cylindrical shape having an upper end opening opened at the upper end and a lower end opening opened at the center of the base portion. When the button is attached to the fabric, the post part of the button stopper cuts and penetrates the fabric, and circular fabric waste is generated. This fabric waste is taken into the interior of the post from the upper end opening of the post. , Dough will not disturb the deformation of the post. Furthermore, since the cover member covers the lower surface of the base part of the fastener body and closes the lower end opening of the post part, the cloth waste generated when the button is attached to the cloth is taken into the post part from the upper end opening of the post part. After that, it is not discharged to the outside from the lower end opening of the post part, and remains in the post part.

  The fastener main body and the cover member in the present invention can be formed by drawing a metal plate such as aluminum, iron, stainless steel alloy, or copper alloy including brass.

  In one embodiment of the present invention, the upper end of the post portion is formed as an edge capable of cutting the fabric with the button when the button is attached to the fabric. By using the upper end of the post portion as an edge, the fabric can be smoothly cut and penetrated by the post portion.

  In one embodiment of the present invention, the post portion includes a folded piece folded back radially inward and downward from the upper end. The folded piece serves to reinforce the tip of the post part or to make the upper edge of the post part more effective.

  In one embodiment of the present invention, the folded piece has, on its inner periphery, a first inclined surface that gently slopes radially inward and downward from the upper end of the post portion, and a radially inner end of the first inclined surface. A second inclined surface that inclines radially inward and downward. The first inclined surface forms an edge of the tip together with the outer peripheral surface of the tip portion of the post portion, and immediately before cutting the fabric at the edge of the post portion, the fabric is pressed against the button side to keep the fabric posture It plays the role of improving the effectiveness of the edge so that the fabric can be cut smoothly.

  In one embodiment of the present invention, the post portion includes a post proximal end portion adjacent to the base portion, a post distal end portion including an upper end, and a post extending linearly between the post proximal end portion and the post distal end portion. And the outer diameter of the post tip portion expands radially outward from the upper end of the post barrel portion, and the maximum outer diameter of the post tip portion is larger than the outer diameter of the post barrel portion. In this way, by expanding the tip end of the post radially outward from the post body, the upper end opening of the post portion is enlarged, and the waste material that the upper end of the post portion cuts when the button is attached to the fabric. It can make it easy to take in in a post part.

  In one embodiment of the present invention, the thickness of the post body part, the post tip part and the folded piece is the vicinity of the upper end of the post part which is the folded part of the folded piece, from the lower end to the upper end of the post body part, The thickness gradually decreases from the upper end to the lower end of the folded piece through the post tip. Thus, by gradually reducing the thickness of the post body, the tip of the post, and the folded piece in this order, the load when folding the folded piece can be reduced compared to the case where the thickness is constant, and the workability is reduced. Will increase.

  According to another aspect of the present invention, there is provided a button structure including a button and a button stopper for attaching the button to the cloth, wherein the button stopper includes a substantially disc-shaped base portion and a base. A fastener body including a post portion that protrudes concentrically with the base portion from the center of the portion, and a cover member that is attached to the stopper body so as to cover the lower surface of the base portion. A base bottom portion adjacent to the post portion and a base flange portion that protrudes upward with respect to the base bottom portion on the radially outer side of the base bottom portion, and the cover member is curved from the lower surface side of the base portion to be bent into the base flange of the base portion The button includes a convex outer portion that protrudes upward and an annular flange portion that extends radially outward from the convex portion, and the convex portion penetrates the fabric. Post part A post receiving part for receiving, deforming and locking is defined inside, and the flange part is a button which faces the curved outer peripheral part across the fabric in a button mounting state in which the post part is locked to the post receiving part. A construct is provided.

  In the present invention, when the button is attached to the cloth, the cloth is sandwiched between the flange part of the button and the curved outer peripheral part of the cover member of the button stopper. Since the base part of the base part is raised further upward than the base flange part that protrudes upward, the distance between the flange part of the button and the curved outer peripheral part facing each other across the cloth when the button is attached is narrow, and the thinner part The button can be attached.

  In one embodiment of the present invention, the post portion has a hollow cylindrical shape having an upper end opening opened at the upper end and a lower end opening opened at the center of the base portion. When the button is attached to the fabric, the post part of the button stopper cuts and penetrates the fabric, and circular fabric waste is generated. This fabric waste is taken into the interior of the post from the upper end opening of the post. , Dough will not disturb the deformation of the post. Furthermore, since the cover member covers the lower surface of the base part of the fastener body and closes the lower end opening of the post part, the cloth waste generated when the button is attached to the cloth is taken into the post part from the upper end opening of the post part. After that, it is not discharged to the outside from the lower end opening of the post part, and remains in the post part.

  In the present invention, the button stopper is composed of a stopper main body and a cover member, and the curved outer peripheral portion of the cover member protrudes further above the base flange portion protruding upward in the base portion of the stopper main body. The button can be securely attached to a thin fabric by narrowing the distance between the curved outer periphery of the button fastener and the button (flange) of the button fastener that sandwiches the fabric with the button fastener attached to the fabric. It becomes possible.

  Also, when the button is attached to the cloth, the post part of the button stopper cuts and penetrates the cloth from its upper end, and the cloth waste generated from the upper end opening of the post part is taken into the post part. There is no adverse effect on the deformation of the post and the connection between the button and the button fastener. Further, in the button fastener, the bottom surface of the base part including the lower end opening of the post part is covered with a cover member, so that the fabric waste taken into the post part from the upper end opening of the post part is not discharged to the outside from the lower end opening. There is no need for separate dough removal work.

  Preferred embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a perspective view and a longitudinal sectional view of a button stopper (hereinafter, also simply referred to as “stopper”) 1 according to an embodiment of the present invention. The stopper 1 is composed of a stopper body 10 and a cover member (shell) 40 formed by drawing a metal plate such as brass or aluminum alloy. The fastener body 10 includes a substantially disc-shaped base portion 20 and a hollow cylindrical post portion 30 that protrudes concentrically with the base portion 20 upward from the center of the base portion 20. (34) (the upper end surface defined by) is opened as an upper end opening 30 ′. The post part 30 has a folded piece 35 obtained by folding the metal plate forming the post part 30 radially inward and downward from the tip 34. As will be described in detail later, the tip 34 of the post portion 30 that is the base end of the folded piece 35 is sharp to facilitate cutting and penetration of the fabric c when the button 50 (see FIG. 4 etc.) is attached to the fabric c. It is formed as a circular edge 34 (hereinafter also referred to as “tip edge”). The lower end of the post portion 30 is opened as a lower end opening 30 ″ at the center of the lower surface of the base portion 20. The cover member 40 is attached to the stopper body 10 so as to cover the base portion 20 from below, and the post portion. The lower end opening 30 ″ of 30 is closed by the cover member 40.

  The post portion 30 (excluding the folded piece 35) gradually rises from the base portion 20, and has a post base end portion 31 whose longitudinal section (inner and outer surfaces) is curved, and extends upward from the post base end portion 31, and has an outer diameter. Is slightly reduced upward, and the post body part 32 in which the longitudinal section (inner and outer surfaces) is linear, and the above-mentioned leading edge 34 whose outer diameter extends radially outward from the upper end of the post body part 32. And a post tip portion 33 including As shown in an enlarged view in FIG. 3, the outer diameter of the post tip portion 33 gradually increases upward from the upper end of the linear outer peripheral surface of the post barrel portion 32 to the maximum, and then the tip edge 34. Gently shrink slightly. The diameter of the tip edge 34 of the post part 30 is larger than the outer diameter of the entire region of the post body part 32. The thickness of the post barrel 32, the post tip 33, and the folded piece 35 is such that the post barrel 32 is formed from the lower end to the upper end, and then the post tip 33 is removed except for the vicinity of the tip edge 34 that is the folded portion of the folded piece 35. After that, the folded piece 35 gradually becomes thinner from the upper end (base end) to the lower end (tip end). Thus, since the thickness is reduced from the lower end of the post body portion 32 to the tip of the folded piece 35, the load when folding the folded piece 35 is smaller and the workability is better than when the thickness is constant. In addition, by the folding | turning of the folding | turning piece 35, since the post front-end | tip part 33 and the folding | turning piece 35 overlap and each thickness is added, the thickness has increased in the vicinity of the said front edge 34.

  The folded piece 35 has a first inclined surface 35a whose inner diameter abruptly decreases radially inward from the leading edge 34 and has a gentle inclination, and a folded piece from the radially inner end of the first inclined surface 35a. The inner diameter is slightly reduced to the lower end of 35, and the second inclined surface 35b has a steep inclination. The first inclined surface 35 a forms a sharp edge 34 together with the outer peripheral surface of the post tip portion 33. The folded piece 35 is partially cut out in a triangular shape from the lower end upward in order to easily reduce the diameter to the lower end. The axial length of the folded piece 35 exceeds that of the post tip 33 and is about ¼ of the height (axial length) of the post 30 from the base 20.

  The base portion 20 includes a base bottom portion 21 that horizontally extends from the lower end of the post base end portion 31 radially outward, and a base flange portion 22 that protrudes upward with respect to the base bottom portion 21 radially outward of the base bottom portion 21. . The base flange portion 22 extends horizontally from the radially outer end of the base bottom portion 21 toward the radially outer side and gradually increases from the radially outer end of the flange inclined portion 22a to the radially outer side. And a flange horizontal portion 22b. The cover member 40 includes a horizontal disc-shaped cover base 41 that covers the lower surface of the base bottom portion 21 including the lower end opening 30 ″ of the post portion 30, and a radially outer end of the base portion 20 from a radially outer end of the cover base 41. The curved outer peripheral portion 42 is folded upward in a C-shaped cross section so as to wrap around the end portion and terminates on the flange horizontal portion 22b. Also rises upwards.

  FIG. 4 shows an arrangement state in the vertical direction (axial direction) of the button 50, the fabric c, and the button stopper 1 when a button (here, a decorative button is illustrated) 50 is attached to the fabric c. The button 50 and the button stopper 1 are an embodiment of the button structure according to the present invention. In the state of FIG. 4, although not shown, the button 50 is held by a lifting unit of a known press machine, and the stopper 1 is placed on the lower die and is concentric with the button 50. The button 50 is a well-known one formed by drawing a metal plate, and is folded back outward and upward in the radial direction from a central convex portion 51 that swells upward in a hemispherical shape, and a lower end portion 52 of the convex portion 51, and then in the radial direction. While extending slightly to the outside, it extends upward until it slightly exceeds the top end of the convex portion 51, and surrounds the convex portion 51, and extends from the upper end of the peripheral side portion 55 while slightly descending radially outward. The outer end in the direction has an annular flange portion 56 that is substantially the same height as the top end of the convex portion 51. The convex portion 51 has a lower end opening 53 in the vicinity of the lower end, and the post portion 30 of the stopper 1 is received from the lower end opening 53 and deformed inside the convex portion 51 when the button 50 is attached to the fabric c. A post receiving portion 54 that is a space for locking is defined. A lower end portion 52 of the convex portion 51 that is a folded portion of the peripheral side portion 55 has a semicircular longitudinal cross section, and its diameter is substantially equal to the thickness of the two metal plates constituting the button 50. The inner diameter of the convex portion 51, that is, the diameter of the post receiving portion 54 is maximum at a position 54 ′ above the lower end opening 53, and after being slightly reduced from the maximum inner diameter position 54 ′ to the lower end opening 53, It expands again to the lower end point 52 '. That is, the lower end opening 53 is slightly above the lowest end point 52 ′ of the lower end portion 52 and is in a position where the inner diameter is minimum in the vicinity of the lower end of the convex portion 51. The diameter of the lower end opening 53 is substantially the same as the diameter of the tip edge 34 of the post portion 30 of the stopper 1. Since the lower end portion 52 of the convex portion 51 has a semicircular cross section as described above, the fabric c can be effectively pressed when the fabric c is cut by the leading edge 34 of the stopper 1 described later. Therefore, hereinafter, the lower end portion 52 of the convex portion 51 is also referred to as a “fabric holding portion 52”.

  When the button 50 is attached to the fabric c using the button fastener 1, the fabric c is sandwiched between the button 50 and the fastener 1 as shown in FIG. 5 by lowering the button 50 from the state shown in FIG. 4. Next, as shown in FIG. 6, the post portion 30 of the stopper 1 cuts and penetrates the fabric c from the tip edge 34, and then enters the post receiving portion 54 of the button 50. Immediately before the cutting of the fabric c in FIG. 5, the fabric c is compressed between the fabric pressing portion 52 of the button 50 and the tip edge 34 of the post portion 30 of the stopper 1, and becomes thin in an annular shape. The portion enters the post receiving portion 54 from the lower end opening 53 of the button 50. In this state, the edge 34 relatively rises and cuts the cloth c. At this time, the first inclined surface 35a of the folded piece 35 of the stopper 1 keeps the position of the cloth c while lifting the cloth c. The effect of 34 is enhanced, and the fabric c is smoothly cut by the edge 34. The circular dough c ′ cut by the edge 34 is received in the post receiving portion 54 as it is.

  As shown in FIG. 7, the post portion 30 penetrating through the cloth c and entering the post receiving portion 54 from the lower end opening 53 of the button 50 is guided upward along the inner surface of the convex portion 51. However, after plastic deformation so that the diameter of the upper end opening 30 ′ is gradually reduced, it is finally crushed and locked in the axial direction as shown in FIG. 8. At the time of FIG. 7, since the fabric waste c ′ is taken into the post portion 30 from the upper end opening 30 ′ of the post portion 30, the fabric waste c ′ does not adversely affect the deformation of the post portion 30. In addition, since the post front end portion 33 extends radially outward, the dough waste c ′ is smoothly taken into the post portion 30. The dough waste c ′ in the post part 30 remains in the stopper 1 (see FIG. 8) because the lower end opening 30 ″ of the post part 30 is closed by the cover member 40. Therefore, it is not necessary to search for and remove the fabric waste c ′ after the button 50 is attached, in the state where the button attachment is completed in FIG. It is crushed along the inner surface of the convex portion 51, that is, matched with the shape of the post receiving portion 54, and cannot be detached from the post receiving portion 54, so that the button 50 and the stopper 1 sandwich the fabric c. Further, the upper end opening 30 ′ of the post part 30 disappears and the cloth waste c ′ remains in the crushed post part 30. Further, the cloth c is the flange part of the button 50. 56 and fastener 1 The cover member 40 is firmly sandwiched between the curved outer peripheral portion 42 and thinned by compression, and the curved outer peripheral portion 42 is further further than the flange horizontal portion 22b that protrudes above the base bottom portion 21 of the base portion 20. Since it comes upward, the space | interval with the flange part 56 can be narrowed, and the button 50 can be reliably attached even to the thin fabric c.

  9 to 11 are longitudinal sectional views of button fasteners 61, 71, 81 according to another embodiment of the present invention, and these fasteners 61, 71, 81 are the fastener main bodies 10a, 10b, 10c. And the cover member 40 (the same reference number is used because it is the same as that of the stopper 1). The stopper bodies 10 a, 10 b, and 10 c are substantially the same as the stopper 1 except for the presence of the post tip and the folded piece. Is different. Therefore, in FIGS. 9-11, the same reference number 20 as FIG.

  The post portion 90 of the stopper 61 shown in FIG. 9 has an outer diameter slightly reduced from the proximal end to the distal end and a longitudinal section extending linearly, and has an upper end opening 90 ′ at the upper end 94. The post front end portion 93 does not extend radially outward with respect to the post body portion 92, and no folded piece is provided. The post portion 100 of the stopper 71 shown in FIG. 10 has a post distal end portion 103 whose outer diameter gradually expands upward from the upper end of the post body portion 102 and expands outward in the radial direction. As a result, the upper end opening 100 ′ is enlarged and the dough waste c ′ is easily taken in. The upper end of the post part 100 is formed as an edge 104, and the diameter of the edge 104 is larger than the outer diameter of the post body part 102. In addition, the folding piece is not provided. The post portion 110 of the fastener 81 shown in FIG. 11 includes a post tip portion 113 that extends outward in the radial direction from the post body portion 112 in the same manner as the fastener 1, and only the folded piece is different from the fastener 1. The folded piece 115 of the stopper 81 extends from the front end edge 114 of the post portion 110 so as to be gently inclined inward in the radial direction. In this case, when the post portion 110 is deformed in the post receiving portion 54 of the button 50 when the button 50 is attached to the fabric c, the folded piece 115 spreads downward and radially outwardly, from which the fabric scraps are removed. c ′ is taken into the post part 110. The post portions 90, 100, 110 of the fasteners 61, 71, 81 each have a lower end opening similar to the lower end opening 30 ″ of the post portion 30 of the fastener 1.

  In FIG. 12, the button 120, which is a decorative button different from the button 50, is provided with the button stopper 1 (the same reference numeral is assigned to the button stopper 1 because it is substantially the same as the button stopper shown in FIG. 1 and the like). It is sectional explanatory drawing similar to FIG. 8 which shows the state attached to cloth | dough c. The button 120 has a convex portion 121 that is convex upward, and an annular flange portion 126 that extends radially outward from the convex portion 121, and a post receiving portion 124 is defined inside the convex portion 121. In the state where the button 120 is attached to the fabric c, the post portion 30 of the button stopper 1 is deformed and locked to the post receiving portion 124 of the button 120, and the flange portion 126 of the button 120 and the button stopper 1 are curved. The fabric c is sandwiched between the outer peripheral portion 42 and the fabric waste c ″ is taken into the post portion 30. Note that the fasteners 61 and 71 of FIGS. 81 can also be used.

  FIG. 13 shows a state in which the button 130 which is a male snap button is attached to the fabric c with the button stopper 1 (which is substantially the same as the button stopper shown in FIG. It is sectional explanatory drawing similar to FIG. The button 130 is convex upward, has a convex portion 131 that is detachably engaged with a concave portion of a female snap button (not shown), and an annular flange portion 136 that extends radially outward from the convex portion 131. A post receiving part 134 is defined inside 131. In a state where the button 130 is attached to the fabric c, the post portion 30 of the button stopper 1 is deformed and locked to the post receiving portion 134 of the button 130, and the flange portion 136 of the button 130 and the button stopper 1 are curved. The fabric c is sandwiched between the outer peripheral portion 42 and the fabric waste c ″ (which is substantially the same as in FIG. 12 and therefore given the same reference number) is taken into the post portion 30.
