Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は靴紐に関するものである。[Detailed explanation of the idea] [Industrial application field] The present invention relates to shoelaces.
靴紐は強く引つ張つて結ぶもので強い引張強度
が要求され、又、雨天にも使用されるので耐腐性
や耐摩耗性が要求される。
Shoelaces are tied with strong tension and are required to have strong tensile strength, and since they are used even in rainy weather, they are required to be rot resistant and abrasion resistant.
このため、靴紐にはナイロン、ポリエステル等
の合成繊維が使用されている。 For this reason, synthetic fibers such as nylon and polyester are used for shoelaces.
靴紐に使用されるナイロン、ポリエステル等の
合成繊維は、雨天の時も吸湿膨潤せず常に一定の
張力を保持する。
Synthetic fibers such as nylon and polyester used for shoelaces do not swell upon moisture absorption and always maintain a constant tension even in rainy weather.
然るに、靴表皮材なかでも皮革は雨天時に吸湿
膨潤して伸び易く、従つて、靴紐自体は伸びない
が次第に弛緩し、再び結び直さなければならなく
なる。 However, among shoe upholstery materials, leather tends to expand due to moisture absorption during rainy weather, and therefore, although the shoelace itself does not stretch, it gradually loosens and must be re-tied.
特に、野外競技の正式試合用の運動靴は皮革で
出来ており、雨天試合の最中に靴が脱げ易くなる
と言う不都合が生じる。 In particular, athletic shoes for official outdoor competitions are made of leather, which causes the inconvenience that the shoes tend to come off during rainy matches.
そこで本考案は、雨天時に靴表皮材が伸びても
靴紐がより一層緊張して靴が脱げにくくなり、結
び直しを要しない靴紐を提供することを目的とす
る。 Therefore, an object of the present invention is to provide a shoelace that does not require retying because the shoelace becomes even more tense even when the shoe skin material stretches during rainy weather, making it difficult to take off the shoe.
本考案に係る靴紐は、一部又は全部が水収縮性
合成繊維により構成されていることを特徴とす
る。
The shoelace according to the present invention is characterized in that part or all of the shoelace is made of water-shrinkable synthetic fiber.
水収縮性合成繊維としてはポリビニルアルコー
ル繊維等の、好ましくは水中に沈めたときの収縮
率が30％以上のもの、例えば未アセタールポリビ
ニルアルコール繊維を使用される。 The water-shrinkable synthetic fibers used include polyvinyl alcohol fibers, preferably those having a shrinkage rate of 30% or more when submerged in water, such as non-acetal polyvinyl alcohol fibers.
靴紐の構造は、合撚紐、組紐、編紐、リボン状
組紐等、従来の靴紐のままでよい。 The structure of the shoelace may be a conventional shoelace such as a twisted string, a braided string, a braided string, or a ribbon-like braided string.
〔実施例 １〕
第１図は合撚構造の靴紐１１を示しており、こ
れではナイロンフイラメント糸１２と水収縮率45
％のポリビニルアルコールフイラメント糸１３と
で下撚した糸条１４に上撚をかけ合撚してつくつ
た。[Example 1] Figure 1 shows a shoelace 11 with a plied structure, in which a nylon filament yarn 12 and a water shrinkage rate of 45 are used.
% of polyvinyl alcohol filament yarn 13, first twisted yarn 14 was twisted, and then twisted together.
〔実施例 ２〕
第２図は編組構造の靴紐１５を示しており、こ
れではナイロンフイラメント糸１６に被覆される
様に組紐の軸芯に水収縮率45％のポリビニルアル
コールフイラメント糸１７を真直ぐに通して編組
してつくつた。[Example 2] FIG. 2 shows a shoelace 15 with a braided structure, in which a polyvinyl alcohol filament thread 17 with a water shrinkage rate of 45% is straightened at the core of the braid so as to be covered with a nylon filament thread 16. It was made by threading it through and braiding it.
かかる本案靴紐によれば、水収縮性合成繊維が
靴紐の端から端まで連続したフイラメント糸であ
るから、雨天時に吸湿収縮し靴紐全体が短くな
る。 According to the shoelace of the present invention, since the water-shrinkable synthetic fiber is a continuous filament yarn from one end of the shoelace to the other, the shoelace absorbs moisture and contracts during rainy weather, shortening the entire shoelace.
特に第２図に示す靴紐１１にあつては、従来の
靴紐に使用されていた糸条（ナイロン糸条）で水
収縮性糸条（ポリビニルアルコール糸条）を被覆
する様につくられ、その外側のナイロン糸条が内
側のポリビニルアルコール糸条を摩耗から保護
し、他方、内側のポリビニルアルコール糸条は長
さ方向に吸湿収縮し同時に膨脹するので外側のナ
イロン糸条から成る組紐外皮の外径も増大せし
め、それによつて組紐外皮が収縮し、結果的に内
側のポリビニルアルコール糸条がナイロン糸条の
収縮を促す恰好になる。 In particular, the shoelace 11 shown in FIG. 2 is made so that water-shrinkable thread (polyvinyl alcohol thread) is covered with thread (nylon thread) used in conventional shoelaces. The outer nylon thread protects the inner polyvinyl alcohol thread from abrasion, while the inner polyvinyl alcohol thread absorbs moisture and contracts in the length direction and expands at the same time. The diameter is also increased, thereby causing the braided outer skin to contract, with the result that the inner polyvinyl alcohol threads are positioned to encourage the contraction of the nylon threads.
したがつて、本考案の靴紐は、雨天時に水収縮
性繊維が吸湿膨脹して結び目が一層硬くなつて解
けにくくなり、又、吸湿収縮するので靴表皮材が
吸湿膨潤しても足にしつかり締め付け、従つて靴
が脱げにくく靴紐の締め直しを不要とする。
Therefore, in the shoelace of the present invention, the water-shrinkable fibers absorb moisture and expand during rainy weather, making the knot even harder and harder to unravel.Also, since the shoelace absorbs moisture and contracts, it does not stick to the foot even if the shoe outer material absorbs moisture and swells. To tighten the shoelaces, thereby making it difficult for the shoes to come off and eliminating the need to retighten the shoelaces.
この様に本考案の靴紐は野外競技用運動靴に極
めて好都合である。 As described above, the shoelace of the present invention is extremely convenient for use in athletic shoes for outdoor sports.
