Definitions
- the present invention relates to a button for buttoning garments and a decorative button mainly used as decoration, specifically, a button to be attached by interposing a fabric between a button body and a fixture.
- buttons attached by interposing a fabric between a button body and a fixture.
- Such button has a button body with a concave portion therein and a fixture with its tip end to be inserted into the concave portion.
- Figs. 4A to 4D show typical examples of this type of conventional button.
- Fig. 4A shows a button body 50 with a common shape, which is widely-used and called "F-bar".
- the button body 50 has an engaging portion 50B with a curved concave portion 50A therein, a folded portion 50C greatly folded back from an opening end of the engaging portion 50B, and a flange 50D extending from the folded portion 50C toward the outside and inclined toward the opening end.
- Fig. 4B shows a button body 51 with a common shape, which is widely-used and called "E-bar".
- the button body 51 has a center portion 51B with a concave portion 51A having a substantially rectangular shape therein, a folded portion 51C slightly folded back from an opening end of the center portion 51B and a flange 51D extending straight from the folded portion 51C toward the outside.
- Fig. 4C shows a shank type rivet 52 as a fixture to be coupled with the button bodies 50, 51.
- the rivet 52 has a flange 52A and a shaft 52B provided at the center of the flange 52A, a tip end of the shaft 52B having a sharp edge.
- Fig. 4D shows a header type rivet 53 as a fixture to be coupled with the button bodies 50, 51.
- the rivet 53 has a flange 53A and a shaft 53B provided at the center of the flange 53A, edges of a tip end of the shaft 53B being cut off.
- a fabric is interposed between the button bodies 50, 51 and the rivets 52, 53.
- the engaging portions 50B, 51B of the button bodies 50, 51 are so formed that parts forming the opening end project from the flanges 50D, 51D to press the fabric. Therefore, since spaces between the flanges 50D, 51D of the button bodies 50, 51 and the flanges 52A, 53A of the rivets 52, 53 are wide, thin fabrics cannot be pressed sufficiently. If the fabric is not pressed sufficiently, the button bodies 50, 51 and the rivets 52, 53 can come off from the fabric unexpectedly. In addition, there is a possibility that foreign bodies or nails of a user are caught between the fabric and the button bodies 50, 51 or the rivets 52, 53.
- forming the flange of the rivet into an inverted-conical shape without changing the shape of the button bodies 50, 51 can be a possible solution, but it is difficult to process the flange into the inverted-conical shape.
- buttons having button bodies and fixtures with specific shapes as shown in Figs. 5A and 5B for attaching a button to a thin fabric.
- Fig. 5A shows a button called “stud”, which has a button body 60 with a concave portion 60A therein and a fixture 61 called “post” and molded with a thin plate.
- the fixture 61 has a flange 61A and a leg 61B formed at the center of the flange 61A, and formed on a tip end of the leg 61B is a flare 61C processed to open toward the outside.
- the fabric is cut between the flare 61C and the concave portion 60A of the button body 60. Therefore, the concave portion 60A of the button body 60 is formed into a specific shape having a narrow opening end and the width being gradually widened toward the inside in order to cut the fabric with the flare 61C.
- Fig. 5B shows a button having a button body 62 called “G-bar” and a fixture 63 called "post rivet”.
- the button body 62 has a specific shape including a front portion 62A formed with its edge folded and an engaging portion 62B with its outer edge engaged with the edge of the front portion 62A and with its inner edge forming a sharp cutting edge 62C.
- the fixture 63 has a flange 63A and a leg 63B formed at the center of the flange 63A, the leg 63B being provided with an inclined portion 63C to cut the fabric with the cutting edge of the engaging portion 62B.
- the button disclosed in Reference 1 has a structure including a button body having a conical projection, an engaging portion with its tip end adapted to bend when abutting on the conical projection and a flange for the engaging portion to be attached to the center thereof, the engaging portion being provided with a plurality of cutting edges arranged circularly to cut the fabric with the button body portion.
- Figs.5A and 5B have a problem in which the attaching structure cannot be utilized for widely-used button bodies such as F-bar and E-bar due to its specific shapes.
- the shape of the concave portion fitted to the flare of the fixture 61 is determined without variation, so that button bodies of the F-bar or E-bar shown in Figs. 4A to 4B " cannot be applied to the fixture 61.
- the flare of the fixture 61 is formed to have thin tip end, when attached to a thick fabric like a denim fabric, the denim fabric cannot be cut sufficiently between the tip end of the flare and the concave portion of the button body. If the fixture 61 is forcibly attached to the thick fabric, the tip end of the flare is deformed, which makes the attachment even more difficult.
- the button disclosed in Reference 1 has a problem in which the cutting edge is deformed or broken when the fabric is thick or stiff.
- the button also has a problem when the fabric is thin or soft, in which the button cannot press the fabric sufficiently and catches the fabric in cutting so that the button cannot be attached to the fabric appropriately.
- EP-A-101065 , EP-A-1110469 and GB-A-2137868 show buttons in which a male member pierces the fabric.
- FR-A- 2553268 shows another button arrangement.

Description
- The present invention relates to a button for buttoning garments and a decorative button mainly used as decoration, specifically, a button to be attached by interposing a fabric between a button body and a fixture.
- Conventionally, there has been known a button attached by interposing a fabric between a button body and a fixture. Such button has a button body with a concave portion therein and a fixture with its tip end to be inserted into the concave portion.
-
Figs. 4A to 4D show typical examples of this type of conventional button. -
Fig. 4A shows abutton body 50 with a common shape, which is widely-used and called "F-bar". Thebutton body 50 has anengaging portion 50B with a curvedconcave portion 50A therein, a foldedportion 50C greatly folded back from an opening end of theengaging portion 50B, and aflange 50D extending from the foldedportion 50C toward the outside and inclined toward the opening end. -
Fig. 4B shows abutton body 51 with a common shape, which is widely-used and called "E-bar". Thebutton body 51 has acenter portion 51B with aconcave portion 51A having a substantially rectangular shape therein, a foldedportion 51C slightly folded back from an opening end of thecenter portion 51B and aflange 51D extending straight from the foldedportion 51C toward the outside. -
Fig. 4C shows ashank type rivet 52 as a fixture to be coupled with thebutton bodies rivet 52 has aflange 52A and ashaft 52B provided at the center of theflange 52A, a tip end of theshaft 52B having a sharp edge.Fig. 4D shows aheader type rivet 53 as a fixture to be coupled with thebutton bodies rivet 53 has aflange 53A and ashaft 53B provided at the center of theflange 53A, edges of a tip end of theshaft 53B being cut off. - In the related arts shown in
Figs. 4A to 4D , a fabric is interposed between thebutton bodies rivets engaging portions button bodies flanges flanges button bodies flanges rivets button bodies rivets button bodies rivets - In order to solve these problems, forming the flange of the rivet into an inverted-conical shape without changing the shape of the
button bodies - With such background, there has been known a related art of buttons having button bodies and fixtures with specific shapes as shown in
Figs. 5A and 5B for attaching a button to a thin fabric. -
Fig. 5A shows a button called "stud", which has abutton body 60 with aconcave portion 60A therein and afixture 61 called "post" and molded with a thin plate. - The
fixture 61 has aflange 61A and aleg 61B formed at the center of theflange 61A, and formed on a tip end of theleg 61B is aflare 61C processed to open toward the outside. The fabric is cut between theflare 61C and theconcave portion 60A of thebutton body 60. Therefore, theconcave portion 60A of thebutton body 60 is formed into a specific shape having a narrow opening end and the width being gradually widened toward the inside in order to cut the fabric with theflare 61C. -
Fig. 5B shows a button having abutton body 62 called "G-bar" and afixture 63 called "post rivet". - The
button body 62 has a specific shape including afront portion 62A formed with its edge folded and anengaging portion 62B with its outer edge engaged with the edge of thefront portion 62A and with its inner edge forming asharp cutting edge 62C. Thefixture 63 has aflange 63A and aleg 63B formed at the center of theflange 63A, theleg 63B being provided with aninclined portion 63C to cut the fabric with the cutting edge of theengaging portion 62B. - Another related art of a button is disclosed in a microfilm (Reference 1) of
Japanese Utility Model Application No. 54-73456 No. 55-173907 U - The button disclosed in Reference 1 has a structure including a button body having a conical projection, an engaging portion with its tip end adapted to bend when abutting on the conical projection and a flange for the engaging portion to be attached to the center thereof, the engaging portion being provided with a plurality of cutting edges arranged circularly to cut the fabric with the button body portion.
- The related arts shown in
Figs.5A and 5B have a problem in which the attaching structure cannot be utilized for widely-used button bodies such as F-bar and E-bar due to its specific shapes. - Especially, for the button shown in
Fig. 5A , the shape of the concave portion fitted to the flare of thefixture 61 is determined without variation, so that button bodies of the F-bar or E-bar shown inFigs. 4A to 4B " cannot be applied to thefixture 61. - Moreover, since the flare of the
fixture 61 is formed to have thin tip end, when attached to a thick fabric like a denim fabric, the denim fabric cannot be cut sufficiently between the tip end of the flare and the concave portion of the button body. If thefixture 61 is forcibly attached to the thick fabric, the tip end of the flare is deformed, which makes the attachment even more difficult. - The button disclosed in Reference 1 has a problem in which the cutting edge is deformed or broken when the fabric is thick or stiff. On the other hand, the button also has a problem when the fabric is thin or soft, in which the button cannot press the fabric sufficiently and catches the fabric in cutting so that the button cannot be attached to the fabric appropriately.

EP-A-101065 EP-A-1110469 andGB-A-2137868 FR-A- 2553268 EP-A-101065 GB-A-2137868 - An object of the present invention is to provide a button that can be attached to a fabric by using a widely-used button body with common shape regardless of thickness and stiffness of the fabric.
- The present invention provides a buttom as set forth in claim 1.
- When the button body and the fixture are pressed to each other with the fabric interposed therebetween, the fabric is cut between the edge formed on the shoulder and the insertion end of the housing of the button body while being pressed by the tip end of the fixture, so that the button can be attached.
- Therefore, the fabric is cut between the edge formed on the shoulder of the fixture and the insertion end of the housing of the button body. For the shoulder, the plate thickness does not have to be thinned compared with that of the flare or the edge shown in the related art, so that it does not face a problem of being damaged even when a big force is applied to the cutting portion. Moreover, its center alignment capability is not deteriorated. Therefore, in the present invention, the fabric can be easily cut without damaging the fixture regardless of the thickness of the fabric. In addition, since the button body is shaped to have the housing in the present invention, a widely-used button body can be used without making any changes by employing a common shape like F-bar, E-bar, etc.
- The edge formed on the shoulder preferably has a curvature radius R of 0.5 mm or less, more preferably 0.3 mm or less.
- By providing the cutting portion on the edge formed between the tip end and the tubular portion, processing of the cutting portion can be facilitated, so that the fixture can be manufactured easily.
- It is preferable that the cutting portion is formed continuously or intermittently on the circumference of the shoulder.
- The fabric can be appropriately and easily cut along the insertion end of the housing.
- The shoulder is hardly deformed, and the damage on the cutting portion can be prevented more efficiently.
- Also, it is preferable that the tip end has a projection projecting from the shoulder.
- The fabric is stretched and pressed by the projection projecting from the shoulder in cutting the fabric between the cutting portion of the fixture and the insertion portion of the housing of the button body, which facilitates cutting the fabric so that the fabric can be cut smoothly without damaging the cutting portion.
- It is preferable that the tip end is adapted to be dented and bulged outwardly when pressed by the button body so that the bulged tip end is engaged with the housing.
- Since the tip end pressed by the button body dents and bulges outwardly in attaching the button, the lateral side of the tip end pressed the lateral side of the housing sufficiently so that detaching force (separation force) of the button is increased. This prevents the button body from unexpectedly coming off from the fixture.
- By making the flange of the fixture into a plate-shaped which is easy to press a thinner fabric, the
edge 12F as the cutting portion of the present invention and theprojection 12E can be provided even if it is processed from a plate, and thus the fabric can be cut easily. The thickness of the plate used as a material of the fixture should preferably be in the range of 0.2 mm to 1 mm, more preferably, 0.3 mm to 0.6 mm. -

fixture 12, as well as thebutton body 11, is made of aluminum, iron, stainless steel alloy, copper alloy including brass or other kind of metals or alloys by an appropriate processing such as press working. - The
fixture 12 has a structure in which atip end 12A having a substantially disk-shaped and inserted into theconcave portion 11A, atubular portion 12B having a substantially cylindrical shape and formed continuously from the tip end 12A, ashoulder 12C formed between the tip end 12A and thetubular portion 12B and aflange 12D having a substantially widened-ring shape and formed continuously from an end of thetubular portion 12B are integrally molded. - The
tip end 12A has aprojection 12E at the center thereof, which has a cylindrical shape with a bottom face and projects toward theconcave portion 11A. Theprojection 12E is adapted to be dented when pressed by thebutton body 11. Since thefixture 12 functions as a rivet, when theprojection 12E is dented to be lower than a flat portion of thetip end 12A, the whole part of the tip end 12A bulges outwardly. Then, the bulgedtip end 12A presses lateral side of theconcave portion 11A to engage. (Fig. 2A ) - The
flange 12D is gradually inclined toward thebutton body 11 at the part closer to the outer periphery. - The
shoulder 12C has anedge 12F formed continuously on its circumference of the outer periphery, and theedge 12F forms a cutting portion to cut the fabric 1 with the openingend 11E of theconcave portion 11A of thebutton body 11. Here, the curvature radius R of theedge 12F is 0.5 mm or less, more preferably 0.3 mm or less. The smaller curvature radius R is more preferable, but the present embodiment employs 0.3 mm to 0.2 mm. The outer diameter of theedge 12F is formed to be same as or little smaller relative to the inner diameter of the openingend 11E of theconcave portion 11A. - The
shoulder 12C has an outer periphery radially bulged relative to thetubular portion 12B. - In order to attach the
button 10 of the first embodiment with the above structure to the fabric 1, the fabric 1 is interposed between thebutton body 11 and thefixture 12, and thetip end 12A of thefixture 12 is pressed against and inserted into theconcave portion 11A of thebutton body 11. - The fabric 1 is cut between the
edge 12F formed on theshoulder 12C and the openingend 11E of theconcave portion 11A of thebutton body 11 while being pressed and stretched by theprojection 12E of thetip end 12A of thefixture 12. - When the
tip end 12A is pressed against theconcave portion 11A, theprojection 12E is dented to be lower than a flat portion of thetip end 12A as shown inFig. 2A , and thus the tip end 12A and the whole part of thetubular portion 12B are bulged outwardly so that it is pressed against and engaged with the lateral side of theconcave portion 11A. - Therefore, in the first embodiment, the following advantages can be obtained.
- (1) The
button body 11 has theconcave portion 11A for thetip end 12A of thefixture 12 to be inserted therein, and thefixture 12 has theshoulder 12C between the tip end 12A and thetubular portion 12B formed continuously from thetip end 12A. Theshoulder 12C has theedge 12F as a cutting portion to cut the fabric 1 with the openingend 11E of theconcave portion 11A of thebutton body 11. Therefore, even when a big force is applied to theedge 12F, theshoulder 12C is not broken due to its sufficient thickness, so that the fabric can be cut easily regardless of the thickness of the fabric. Further, since thebutton body 11 has a shape with theconcave portion 11A therein, F-bar type button body can be used without making any changes. - (2) Since the cutting portion is the
edge 12F formed on theshoulder 12C, processing of the cutting portion can be facilitated, so that the fixture can be manufactured easily. - (3) Since the
shoulder 12C has the outer periphery radially bulged relative to thetubular portion 12B, theshoulder 12C is hardly deformed, and damage on thefixture 12 can be prevented more effectively. - (4) The
tip end 12A has theprojection 12E projecting from theshoulder 12C. Therefore, when the fabric 1 is cut between theedge 12F of thefixture 12 and the openingend 11E of theconcave portion 11A of thebutton body 11, theprojection 12E projecting from theshoulder 12C presses and stretches the fabric 1, so that the fabric 1 can be cut easily and smoothly without damaging theedge 12F as the cutting portion. - (5) The
projection 12E is dented when pressed against thebutton body 11 and thetip end 12A is bulged outwardly so that the bulgedtip end 12A is engaged with theconcave portion 11A. With such structure, the lateral side of the tip end 12A sufficiently presses the lateral side of theconcave portion 11A of thebutton body 11, and thus the detaching force (separation force) of the button can be improved. This prevents thebutton body 11 from unexpectedly coming off from thefixture 12. - (6) Since the flange of the fixture is made into a plate-shaped which is easy to press a thinner fabric, the
edge 12F as the cutting portion and theprojection 12E can be provided even if it is processed from a plate, and thus the fabric can be cut easily. The thickness of the plate used as a material of the fixture should preferably be in the range of 0.2 mm to 1 mm, more preferably, 0.3 mm to 0.6 mm. - Next, a second embodiment of the present invention will be described. The second embodiment only differs in the structure of a button body, and the structure of the fixture is the same with the
fixture 12 of the first embodiment. In the description of the second embodiment, for the components identical to those in the first embodiment, the same numerals are attached to omit the description thereof. - The present embodiment is applied to a decorative button.
-
Fig. 1B shows a cross section showing a second embodiment. - In
Fig. 1B , abutton 20 has abutton body 21 and thefixture 12 attached to each other with the fabric 1 interposed therebetween. - The
button body 21 is called F-bar and has the same structure as the button body shown inFig. 4A . Thebutton body 21, as thebutton body 11 in the first embodiment, is made of aluminum, iron, stainless steel alloy, copper alloy including brass, or other kind of metals or alloys by an appropriate processing such as press working, and has a structure in which acenter portion 21B provided with aconcave portion 21A as a housing, a foldedportion 21C slightly folded back from an opening end of thecenter portion 21B and theflange 21D extending from the foldedportion 21C toward the outside are integrally molded. - The
center portion 21B is formed to have a cylindrical shape with a bottom face, and the inner side thereof is theconcave portion 21A. Theconcave portion 21A has a curved shape with its openingend 21E rounded by appropriate curvature. - The folded
portion 21C is inverted from thecenter portion 21B to extend to the vicinity of the top of thecenter portion 21B, and theflange 21D extends at approximately square angle from an end of the foldedportion 21C. Theflange 21D shapes like a widened ring. - In order to attach the
button 20 of the second embodiment with such structure to the fabric 1, the fabric 1 is interposed between thebutton body 21 and thefixture 12, and thetip end 12A of thefixture 12 is pressed against and inserted into theconcave portion 21A of thebutton body 21 as in the first embodiment. - Then, the fabric 1 is cut between the
edge 12F formed on theshoulder 12C and the openingend 21E of theconcave portion 21A of thebutton body 21 while being pressed and stretched by theprojection 12E of thetip end 12A of thefixture 12. - When the
tip end 12A is pressed against theconcave portion 21A, theprojection 12E is dented to be lower than the flat portion of thetip end 12A, and thus the whole part of thetip end 12A is bulged outwardly so that it is pressed against and engaged with the lateral side of theconcave portion 21A. - Therefore, in the second embodiment, advantages similar to (1) to (6) of the first embodiment can be obtained.
- Incidentally, the scope of the present invention is not restricted to the above-described embodiments, but includes modifications and improvements as long as an object of the present invention can be achieved.
- For instance, in the second embodiment, the housing is the
concave portion 21A and the insertion end is theopening end 21E, but the structures of the housing and the insertion portion are not limited to the embodiment. For instance, as shown inFig. 3A , the housing of thebutton body 21 may have a shape with anopening 21G formed on the top thereof. In such case, aninsertion end 21H is an opening located opposite to theopening 21G. A numeral 30 denotes a button attaching tool. In the present invention, as shown inFig. 3B , a structure in which ashell 12G is attached to theflange 12D of thefixture 12 may be employed. - In the above-described embodiments, applications for decorative buttons are exemplified. However, the present invention is for buttoning garments, and it may be applied to a button for practical use. Further, the button of the present invention may also be used for items other than garments.
- In the present invention, the
tubular portion 12B is not limited to a cylindrical shape, and a squared tubular portion shape may also be employed. - The cutting portion is not limited to the one formed continuously on the circumference of the
shoulder 12C, but the one formed intermittently may also be employed. In such case, by perforating the fabric 1 and pressing the cutting portion against the fabric 1, the fabric 1 can be cut.
