Description
本考案は、スナップボタンに関し、更に詳しくは、雄スナップボタン又は雌スナップボタンの相互に係合する側の面に装飾を施した金属製のスナップボタンに関する。 The present invention relates to a snap button, and more particularly to a metal snap button in which a male snap button or a surface of a female snap button that is engaged with each other is decorated.
雄スナップボタンと雌スナップボタンを相互に着脱させるスナップボタンは衣類、鞄類等に広く使用されている。雄スナップボタンと雌スナップボタンの着脱は、雄スナップボタンの係合部である突起部を、雌スナップボタンの係合部である突起受け入れ部に対して係合及び脱係合させることにより行われる。また、金属製のスナップボタンにおいて、表面側に色、模様、ロゴ等を含む装飾が印刷等により施されているものが一般的に知られている。例えば、実開平６−６９２０１号公報には、スナップボタンの係合部とは反対側の外表面に、ワンポイントの装飾を刺繍、シール、印刷等により施す技術が開示されている。これに対し、金属製のスナップボタンにおいて、雄スナップボタンと雌スナップボタン間の係合動作を担う係合部が存在する側の面は、ユーザから見て裏側であるため、また、経時的な着脱動作により剥離等のおそれがあるため、装飾等は施されていないのが現状である。しかしながら、スナップボタンのファッション性を高める観点から、スナップボタンの係合部側の面にも装飾を付与する要請がある。 Snap buttons that allow a male snap button and a female snap button to be attached to and detached from each other are widely used in clothing, potatoes, and the like. The male snap button and the female snap button are attached / detached by engaging and disengaging the protrusion that is the engaging part of the male snap button with the protrusion receiving part that is the engaging part of the female snap button. . Further, a metal snap button is generally known in which a decoration including a color, a pattern, a logo, and the like is applied to the surface side by printing or the like. For example, Japanese Utility Model Laid-Open No. 6-69201 discloses a technique in which a one-point decoration is applied to the outer surface opposite to the engaging portion of the snap button by embroidery, sealing, printing, or the like. On the other hand, in the metal snap button, the surface on the side where the engaging portion responsible for the engaging operation between the male snap button and the female snap button exists is the back side as viewed from the user. Since there is a risk of peeling or the like due to the attachment / detachment operation, the present situation is that no decoration or the like is applied. However, from the viewpoint of improving the fashionability of the snap button, there is a demand to add decoration to the surface of the snap button engaging portion side.

In the present invention, the male snap may be composed of (a) one part that does not include a stopper 30 to be described later, or (b) two parts that include the stopper 30. In the case of (b), the male snap 10 is also called a male snap main body 10. FIG. 2 is a cross-sectional view taken along line AA in FIG. FIG. 3 is a perspective view of the male snap 10. The male snap 10 is formed by drawing a single metal plate, and has a projection 11 as a central engaging portion and a base end, that is, a lower end of the projection 11 (hereinafter, the upper and lower sides of the male snap 10). Is based on the paper surface of FIG. 2) and a flange portion 14 extending radially outward. The protruding portion 11 includes a cylindrical portion 12 and an upper end portion 13 that closes the upper end side of the cylindrical portion 12. The lower end side of the cylindrical part 12 is opened. The cylindrical portion 12 has a lower end portion 12a that is inclined in a straight line so that the diameter gradually decreases from the radially inner end of the flange portion 14 and a constant diameter extending upward from the upper end of the lower end portion 12a. An intermediate portion 12b, a hollow portion 12c whose diameter is curved radially inward from the upper end of the intermediate portion 12b, and an outer bulge continuously curved upward and radially outward from the hollow portion 12c. Part 12d. The upper end of the outer bulging portion 12d is connected to the upper end portion 13 while being curved inward in the radial direction. The maximum outer diameter of the outer bulging portion 12d is substantially equal to the outer diameter of the intermediate portion 12b. The upper end portion 13 is recessed in a mortar shape downward from the radially outer side to the inner side, that is, the center.
フランジ部１４は、円筒部１２の下端から半径方向外側かつ上方へと断面直線状に延びる傾斜部１４ａと、傾斜部１４ａの半径方向外側端から若干上方に凸となる湾曲状に隆起しつつ半径方向外側へと延びた後、下方へ次いで半径方向内側へと断面Ｃ字状に湾曲されて終端する湾曲外周部１４ｂとを含む。湾曲外周部１４ｂは、突起部１１が存在する表側から見える上方側の外周上部１４ｂａと、表側から見えない裏側すなわち下方側の外周下部１４ｂｂとに区分される。雄スナップ１０の裏側において、外周下部１４ｂｂの半径方向内側端と、傾斜部１４ａとの間には、湾曲外周部１４ｂの内部空間に通じる環状の開口１５が生じる。詳しくは後述するが、図１１に示すように雄スナップ１０を止具３０で生地ｆに取り付ける際、止具３０の爪部３２（図９等参照）が生地ｆを貫通した後、開口１５から湾曲外周部１４ｂの内部空間で加締められる。 The flange portion 14 has a slope portion 14a extending linearly outward and upward in the radial direction from the lower end of the cylindrical portion 12, and a radius while projecting slightly upward from the radially outer end of the slope portion 14a. A curved outer peripheral portion 14b that extends outward in the direction and is then curved downward and then radially inward in a C-shaped cross section. The curved outer peripheral portion 14b is divided into an upper outer peripheral upper portion 14ba that can be seen from the front side where the protrusions 11 are present, and a back side that is invisible from the front side, that is, a lower outer peripheral lower portion 14bb. On the back side of the male snap 10, an annular opening 15 communicating with the internal space of the curved outer peripheral portion 14b is formed between the radially inner end of the outer peripheral lower portion 14bb and the inclined portion 14a. As will be described in detail later, when the male snap 10 is attached to the fabric f with the stopper 30 as shown in FIG. 11, after the claw portion 32 (see FIG. 9 etc.) of the stopper 30 penetrates the fabric f, It crimps in the internal space of the curved outer peripheral part 14b.
上述した雄スナップ１０には、フランジ部１４の表面側、すなわち、傾斜部１４ａの上面と、湾曲外周部１４ｂの外周上部１４ｂａの上面に装飾層１（図１及び３において網掛けで示す。）が設けられている。装飾層１は、色、模様、ロゴ等を含むデザインを呈する層であり、例えばＵＶ硬化樹脂からなる塗膜であり得る。装飾層１は、容易に剥離しないように下処理層２の上に印刷等によって形成される。図４は、装飾層１及び下処理層２を便宜的に示す断面説明図である。下処理層２は、例えば、雄スナップ１０をなす基材（金属材料）の表面上に形成されたメッキ層２ａと、メッキ層２ａの上に形成されたシランカップリング層２ｂと、シランカップリング層２ｂの上に形成された樹脂層２ｃとからなる。メッキ層２ａは、例えば銅−スズメッキ層であり得る。樹脂層２ｃをなす樹脂としては、例えば、ウレタン樹脂、アクリル樹脂、シリコン樹脂、フッ素樹脂、エポキシ樹脂、アルキド樹脂等を使用することができるが、装飾層１の剥離防止の観点からウレタン系樹脂が最も好ましいと考えられる。本実施形態では、一例として樹脂層２ｃとしてウレタン系２液イソシアネート層を用いた。また、メッキ層２ａはエナメル層に置き換えられる場合もあり得る。装飾層１は、下処理層２を形成した後の雄スナップ１０に対しインクジェットプリンターによる印刷によって形成され得る。なお、下処理層２は図１〜３には表していない。 In the male snap 10 described above, the decorative layer 1 (shown by shading in FIGS. 1 and 3) on the surface side of the flange portion 14, that is, the upper surface of the inclined portion 14a and the upper surface of the outer peripheral upper portion 14ba of the curved outer peripheral portion 14b. Is provided. The decoration layer 1 is a layer exhibiting a design including a color, a pattern, a logo, and the like, and may be a coating film made of, for example, a UV curable resin. The decoration layer 1 is formed on the lower treatment layer 2 by printing or the like so as not to easily peel off. FIG. 4 is an explanatory cross-sectional view showing the decorative layer 1 and the lower treatment layer 2 for convenience. The undertreatment layer 2 includes, for example, a plating layer 2a formed on the surface of the base material (metal material) forming the male snap 10, a silane coupling layer 2b formed on the plating layer 2a, and a silane coupling. And a resin layer 2c formed on the layer 2b. The plating layer 2a can be, for example, a copper-tin plating layer. As the resin forming the resin layer 2c, for example, urethane resin, acrylic resin, silicon resin, fluorine resin, epoxy resin, alkyd resin, and the like can be used. Most preferred. In the present embodiment, as an example, a urethane two-component isocyanate layer is used as the resin layer 2c. Further, the plating layer 2a may be replaced with an enamel layer. The decorative layer 1 can be formed by printing with an ink jet printer on the male snap 10 after forming the undertreatment layer 2. The undertreatment layer 2 is not shown in FIGS.
装飾層１は、雄スナップ１０の表側において突起部１１には設けられていない。なお、突起部１１の基端側に装飾層１が多少かかることは許容され得る。突起部１１は、使用において後述する雌スナップボタン２０の係合部である突起受け入れ部２１（図７等参照）と係合動作を行う部分であるため、経時的に装飾層１が剥離するおそれがあるためである。装飾層１が突起部１１に形成されないのに対し、下処理層２は装飾層１の範囲を超えて形成され得る。例えば、メッキ層２ａは、雄スナップ１０の突起部１１や外周下部１４ｂｂの下面を含む雄スナップ１０の外表面全域に設けられ得る。シランカップリング層２ｂと樹脂層２ｃは、装飾層１の範囲をわずかでも上回るように形成することが、装飾層１の縁からの経時的な剥離を防ぐために望ましい。そのため、例えば、シランカップリング層２ｂと樹脂層２ｃは、突起部１１の下端部１２ａの外周面や外周下部１４ｂｂの下面の半径方向外側部分に及ぶように形成され得る。 The decorative layer 1 is not provided on the protrusion 11 on the front side of the male snap 10. It should be noted that the decorative layer 1 may be allowed to be somewhat applied to the base end side of the protruding portion 11. Since the protrusion 11 is a part that engages with a protrusion receiving part 21 (see FIG. 7 and the like) that is an engaging part of a female snap button 20 to be described later in use, the decorative layer 1 may be peeled off over time. Because there is. While the decorative layer 1 is not formed on the protrusions 11, the undertreatment layer 2 can be formed beyond the range of the decorative layer 1. For example, the plating layer 2a can be provided on the entire outer surface of the male snap 10 including the protrusion 11 of the male snap 10 and the lower surface of the outer peripheral lower portion 14bb. It is desirable to form the silane coupling layer 2b and the resin layer 2c so that they slightly exceed the range of the decorative layer 1 in order to prevent peeling over time from the edge of the decorative layer 1.
