Description

【0001】
【発明の属する技術分野】
本発明は、ボタンに関するものである。
【0002】
【従来の技術】
従来、ボタンAは、図4に示すように、ほぼ均一の厚さの円板状に形成されており、中央部分に縫い糸Cが挿通される糸通し穴Bが形成されている。そして、糸通し穴Bに挿通された縫い糸Cを布地Xに縫い付けて、ボタンAを衣類等の布地Xに止着している。
【0003】
【発明が解決しようとする課題】
しかしながら、上記のボタンAは、底面Dが平らであるため、布地XにボタンAを縫着した際に、ボタンAと布地Xとの隙間Sが非常に狭小となる。したがって、ボタンAを手指でつまみにくく、特に、指先を動かしにくい老人や子供などは、ボタンホールに掛け外しする動作が非常に困難となり、場合によっては他人の介助が必要となる不具合がある。
【0004】
本発明は上記問題点に鑑みて提案されたものであって、誰でも簡単に掛け外しすることのできるボタンを提供することを目的とする。
【0005】
【課題を解決するための手段】
以上の目的を達成するために、本発明のボタンは、
ボタンの裏面に、底面部と、底面部からボタンの外周縁に向かってボタンの厚さが減少する傾斜面部が設けられており、底面部に対する傾斜面部の傾斜角度が15°から50°の範囲であることを特徴とするものである。なお、前記傾斜角度は約30°であることが最も好ましい。
【0006】
【発明の実施の形態】
以下に、本発明の実施の形態を詳細に説明する。
【0007】
本実施形態のボタン1は、通常シャツやブラウス等に用いられるもので、図1、図2に示すように、直径が約10mmで、中央部分の厚さが約3mm、周縁の厚さが約1mmの平面視円形状に形成されている。
ボタン1の表面には、凹面部2が形成されており、凹面部2の周縁からボタン1の周縁に向かってボタンの厚さが減少する表側傾斜面部3が設けられている。ボタン1の裏面には、その中央に底面部4が形成されており、また、底面部4の周縁部外方には、底面部4の周縁からボタン1の外周縁に向かってボタンの厚さが減少する傾斜面部としての裏側傾斜面部5が設けられている。
【0008】
ここで、図2に示すように、裏側傾斜面部5の底面部4に対する傾斜角度をθとすると、裏側傾斜面部5は、傾斜角度θが30°となるように設けられている。
【0009】
また、凹面部2と底面部4とは、糸通し穴6により連通している。
【0010】
なお、ボタン1は、不飽和ポリエステル樹脂製で、切削加工により形成されている。
【0011】
ボタン1は、図3に示すように、糸通し穴6にそれぞれ挿通された縫い糸7を衣類等の布地Xに縫い付けることにより、布地Xに縫着されている。
そして、ボタン1を図示しないボタンホールに掛止させる際には、図3に示すように、例えば、親指と人差し指とを用いてボタン1の周縁部をつまむ。
【0012】
このとき、人差し指をボタン1の表側傾斜面部3の一部に当接させて、ボタン1の周縁を布地X側に押し付けると、押し付けた部分と反対側の周縁が布地Xに対して持ち上がり、ボタン1の周縁と布地Xとの間の隙間Sが拡大する。そして、大きく開いた隙間Sに親指Eを挿入し、親指Eをボタン1の裏面側傾斜面部5に当接させることにより、ボタン1を親指Eと人差し指Fとでつまむ。
【0013】
以上のように、本実施形態のボタン1は、ボタン裏面に底面部4と裏側傾斜面部5とを設けたものであるので、布地Xにボタン1を止着した際に、ボタン1と布地Xとの間に、底面部4の周縁からボタン1の外周縁に向かって拡開する隙間が形成される。したがって、ボタン1と布地Xとの隙間Sに指先を入れやすく、誰でも簡単かつ確実にボタン1をつまむことができる。さらに、上述したように、ボタンの周縁の一部を布地X側に押し付けると、押し付けた部分と反対側の周縁が布地Xに対して持ち上がるため、ボタン1の周縁と布地Xとの間の隙間Sが、より大きく開く。したがって、ボタン1と布地Xとの隙間Sにさらに指先を入れやすい状態となるため、容易かつ確実にボタン1をつまむことができる。このように、本実施の形態のボタン1は、誰でも簡単につまんで掛け外しすることができる。
【0014】
ところで、本願発明者は、ボタン1と布地Xとの間に形成される隙間Sに指先を入れやすく、ボタンの掛け外しを容易にするために、裏側傾斜面部5の傾斜角度θの異なるものを多数形成して実験を行った。その結果、傾斜角度θが10°未満であると、裏側傾斜面部5と布地Xとの間に、手指を差し入れるだけの隙間がほとんど形成されず、従来のボタンと同様に掛け外しがしにくいという問題が生じ、傾斜角度θが50°を越えると、裏側傾斜面部5が非常に急な傾斜面を形成するため、手指を当接させるに十分な面積を得ることができず、裏側傾斜面部5に手指を当接した場合に、手指が滑ってボタン1の掛け外しがスムーズに行えないという問題が生じた。
【0015】
すなわち、傾斜角度θの値は、15°から50°までの範囲が好ましいという結論を得るとともに、傾斜角度θの値の最適値は、30°であるという結論を得たのである。
【0016】
つまり、本実施の形態のボタン1は、裏側傾斜面部の傾斜角度θが30°であるので、ボタン1と布地Xとの間に形成される隙間Sに指先を入れやすい上、指先を裏側傾斜面部5にフィットさせやすいため、誰でも簡単に掛け外しができる。
【0017】
また、ボタン1は、裏側傾斜面部5だけでなく表側傾斜面部3をも設けたものであるので、手指を表側傾斜面部3および裏側傾斜面部5にそれぞれ確実に当接させることができる。したがって、各指先をボタン1にさらに良好にフィットさせることができるため、ボタン1を確実につまむことができる。
【0018】
なお、本実施の形態では、裏側傾斜面部5だけでなく表側傾斜面部3も設けたが、表側傾斜面部3は必ずしも必要ではない。
【0019】
また、ボタン1の材質は、不飽和ポリエステル樹脂に限られず、他の合成樹脂、例えば、ナイロン樹脂、ユリア樹脂、ABS樹脂あるいはシリコン樹脂等であってもよい。また、貝等の天然素材や金属であってもよい。
【0020】
また、製造方法は、切削加工に限定されず、射出成形でもよい。
【0021】
また、裏側傾斜面部5の傾斜角度θを30°としたが、この角度に限られることはなく、10°から50°の範囲であればよい。
【0022】
また、裏側傾斜面部5の傾斜面は、図2に示すように縦断面視直線状に形成されているが、必ずしも直線状に形成されていなくてもよい。すなわち、やや凸状に膨らんだ形状でもよいし、やや凹状にへこんだ形状をしていても構わない。
【0023】
さらに、表側傾斜面部3、裏側傾斜面部5の傾斜面は、平滑でなくてもよく、粗面に形成してもよい。すなわち、例えば、傾斜面に細い溝を多数形成することにより、傾斜面に滑り止め加工を施してもよい。このようにすれば、より一層ボタン1を手指で確実につまむことができる。
【0024】
また、本実施の形態では、ボタン1の大きさは、シャツやブラウス等に用いるボタンとして好適な大きさである直径約10mmに形成したが、ボタンの大きさはこれに限られず、例えば、パジャマ等に用いるボタンとして好適な大きさである直径約18mmから20mm程度に形成したものでもよい。
【0025】
【発明の効果】
以上のごとく本発明のボタンは、
ボタンの裏面に、底面部と、底面部からボタンの外周縁に向かってボタンの厚さが減少する傾斜面部が設けられており、底面部に対する傾斜面部の傾斜角度が15°から50°の範囲であるので、
布地にボタンを止着した際に、ボタンと布地との間に、底面部からボタンの外周縁に向かって拡開する隙間が形成されるため、ボタンと布地との隙間に指先を入れやすく、誰でも簡単かつ確実にボタンをつまむことができる。
また、ボタンの周縁の一部を布地側に押し付けると、押し付けた部分と反対側の周縁部が布地に対して持ち上がり、ボタンの周縁と布地との間により大きな隙間が形成されるため、ボタンと布地との隙間にさらに指先を入れやすくなり、誰でも容易かつ確実にボタンをつまむことができる。
したがって、本発明のボタンによれば、誰でも簡単にボタンの掛け外し動作をすることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to buttons.
[0002]
[Prior art]
Conventionally, as shown in FIG. 4, the button A is formed in a disk shape having a substantially uniform thickness, and a threading hole B through which a sewing thread C is inserted is formed at a central portion. Then, the sewing thread C inserted through the threading hole B is sewn to the cloth X, and the button A is fixed to the cloth X such as clothing.
[0003]
[Problems to be solved by the invention]
However, since the bottom surface D of the button A is flat, when the button A is sewn to the cloth X, the gap S between the button A and the cloth X is very small. Therefore, it is very difficult for an elderly person, a child, or the like, who has difficulty in pinching the button A with his / her finger, and who has difficulty moving their fingertips, to detach the button A from the buttonhole. In some cases, there is a problem that the assistance of another person is required.
[0004]
The present invention has been proposed in view of the above problems, and has as its object to provide a button that can be easily removed by anyone.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the button of the present invention
On the back surface of the button, there is provided a bottom portion and an inclined surface portion in which the thickness of the button decreases from the bottom portion toward the outer peripheral edge of the button, and the inclination angle of the inclined surface portion with respect to the bottom portion is in a range of 15 ° to 50 °. It is characterized by being. Most preferably, the inclination angle is about 30 °.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
[0007]
The button 1 of the present embodiment is generally used for a shirt, a blouse, or the like, and has a diameter of about 10 mm, a thickness of about 3 mm at a central portion, and a thickness of about 3 mm as shown in FIGS. It is formed in a circular shape in plan view of 1 mm.
A concave portion 2 is formed on the surface of the button 1, and a front-side inclined surface portion 3 in which the thickness of the button decreases from the periphery of the concave portion 2 toward the periphery of the button 1 is provided. On the back surface of the button 1, a bottom surface portion 4 is formed at the center thereof, and on the outer side of the periphery of the bottom surface portion 4, the thickness of the button extends from the periphery of the bottom surface portion 4 toward the outer periphery of the button 1. The rear side inclined surface portion 5 is provided as an inclined surface portion in which the number of slashes decreases.
[0008]
Here, as shown in FIG. 2, assuming that the inclination angle of the back side inclined surface portion 5 with respect to the bottom surface portion 4 is θ, the back side inclined surface portion 5 is provided such that the inclination angle θ is 30 °.
[0009]
Further, the concave surface portion 2 and the bottom surface portion 4 communicate with each other through a threading hole 6.
[0010]
The button 1 is made of an unsaturated polyester resin, and is formed by cutting.
[0011]
As shown in FIG. 3, the button 1 is sewn to the cloth X by sewing the sewing thread 7 inserted into the threading hole 6 to the cloth X such as clothing.
Then, when the button 1 is engaged with a button hole (not shown), as shown in FIG. 3, the peripheral edge of the button 1 is grasped using, for example, a thumb and an index finger.
[0012]
At this time, when the index finger is brought into contact with a part of the front side inclined surface portion 3 of the button 1 and the periphery of the button 1 is pressed against the fabric X, the periphery opposite to the pressed portion is lifted with respect to the fabric X, and the button X is lifted. The gap S between the peripheral edge of the cloth 1 and the cloth X increases. Then, the thumb E is inserted into the widely opened gap S, and the thumb E is brought into contact with the rear side inclined surface portion 5 of the button 1, whereby the button 1 is pinched between the thumb E and the index finger F.
[0013]
As described above, since the button 1 of the present embodiment has the bottom surface portion 4 and the back side inclined surface portion 5 provided on the back surface of the button, when the button 1 is fixed to the fabric X, the button 1 and the fabric X A gap that expands from the peripheral edge of the bottom surface portion 4 toward the outer peripheral edge of the button 1 is formed between them. Therefore, it is easy to put a fingertip into the gap S between the button 1 and the cloth X, and anyone can easily and reliably pinch the button 1. Further, as described above, when a part of the peripheral edge of the button is pressed against the fabric X, the peripheral edge opposite to the pressed portion is lifted with respect to the fabric X, so that the clearance between the peripheral edge of the button 1 and the fabric X is increased. S opens wider. Therefore, the fingertip can be more easily inserted into the gap S between the button 1 and the cloth X, so that the button 1 can be easily and reliably pinched. As described above, the button 1 of this embodiment can be easily picked up and removed by anyone.
[0014]
By the way, in order to make it easy to put a fingertip into the gap S formed between the button 1 and the cloth X and to make it easy to hang the button, the inventor of the present application proposes a device having a different inclined angle θ of the rear inclined surface portion 5. An experiment was conducted by forming a large number. As a result, when the inclination angle θ is less than 10 °, there is hardly formed a gap between the back side inclined surface portion 5 and the cloth X for inserting a finger, and it is difficult to remove the same as in the conventional button. When the inclination angle θ exceeds 50 °, the rear-side inclined surface portion 5 forms a very steep inclined surface, so that it is not possible to obtain a sufficient area for bringing the fingers into contact with the rear-side inclined surface portion. In the case where the finger abuts on the button 5, there is a problem that the finger slips and the button 1 cannot be smoothly removed.
[0015]
That is, it was concluded that the value of the inclination angle θ was preferably in the range of 15 ° to 50 °, and it was also concluded that the optimum value of the inclination angle θ was 30 °.
[0016]
That is, in the button 1 of the present embodiment, since the inclination angle θ of the back side inclined surface portion is 30 °, it is easy to put a fingertip into the gap S formed between the button 1 and the cloth X, and the fingertip is inclined backside. Since it is easy to fit to the surface 5, anyone can easily remove it.
[0017]
Further, since the button 1 is provided with not only the back side inclined surface portion 5 but also the front side inclined surface portion 3, it is possible to reliably bring the finger into contact with the front side inclined surface portion 3 and the back side inclined surface portion 5. Therefore, each fingertip can be more properly fitted to the button 1, so that the button 1 can be reliably pinched.
[0018]
In the present embodiment, not only the rear-side inclined surface 5 but also the front-side inclined surface 3 is provided, but the front-side inclined surface 3 is not necessarily required.
[0019]
The material of the button 1 is not limited to the unsaturated polyester resin, but may be another synthetic resin such as a nylon resin, a urea resin, an ABS resin, or a silicone resin. Further, it may be a natural material such as a shellfish or a metal.
[0020]
Further, the manufacturing method is not limited to cutting, but may be injection molding.
[0021]
Further, the inclination angle θ of the back side inclined surface portion 5 is set to 30 °, but is not limited to this angle and may be in the range of 10 ° to 50 °.
[0022]
The inclined surface of the back-side inclined surface portion 5 is formed in a straight line in a longitudinal sectional view as shown in FIG. 2, but is not necessarily formed in a straight line. That is, it may have a slightly convex shape or a slightly concave shape.
[0023]
Further, the inclined surfaces of the front-side inclined surface portion 3 and the back-side inclined surface portion 5 do not have to be smooth, and may be formed as rough surfaces. That is, for example, a non-slip process may be performed on the inclined surface by forming many thin grooves on the inclined surface. By doing so, the button 1 can be more reliably pinched with the fingers.
[0024]
Further, in the present embodiment, the size of the button 1 is formed to be about 10 mm in diameter, which is a size suitable for a button used for a shirt, a blouse, or the like. However, the size of the button is not limited to this. The button may be formed to have a diameter of about 18 mm to about 20 mm, which is a suitable size for the button used for the purpose.
[0025]
【The invention's effect】
As described above, the button of the present invention
On the back surface of the button, there is provided a bottom portion and an inclined surface portion in which the thickness of the button decreases from the bottom portion toward the outer peripheral edge of the button, and the inclination angle of the inclined surface portion with respect to the bottom portion is in a range of 15 ° to 50 °. So
When the button is fastened to the fabric, a gap is formed between the button and the fabric that expands from the bottom to the outer edge of the button, so it is easy to put a fingertip into the gap between the button and the fabric, Anyone can easily and reliably pinch the button.
Also, when a part of the peripheral edge of the button is pressed against the fabric, the peripheral portion opposite to the pressed portion is lifted with respect to the fabric, and a larger gap is formed between the peripheral edge of the button and the fabric. It is easier to put a fingertip into the gap with the fabric, and anyone can pinch the button easily and reliably.
Therefore, according to the button of the present invention, anyone can easily perform the operation of detaching the button.
