基本繩結 - 外科醫生結 (1) Surgeon's Knot

基本繩結 - 外科醫生結 Surgeon's Knot (1)


從英文直譯的話，Surgeon's Knot就是外科醫生結。因為這個繩結確實有應用在外科手術的縫合，因而得到此名，不過還有另一個用雙線直結的繩結也叫這個名字，這點有些容易讓人混淆。

這個結由平結變化而來，打的時候只要把平結的兩條線再多繞一圈就行了。特徵是因摩擦阻力提升而不容易解開。使用容易鬆脫的粗繩打結時，這個結就能夠派上用場。即使兩條線纏繞著也能拉緊，很常用於把東西束好固定。和平結一樣，如果顛倒兩條線交叉的上下順序，就會打成讓強度大打折扣的縱結，所以要特別注意。

如果用細的繩子打結，兩條線可以多纏繞幾圈，不過線頭交叉的時候，纏繞的次數和平常一樣就好。不過，這個方法的缺點是會增加結頭旳體積，容易讓兩條繩子之間產生空隙，如果繩子太細（2號以下）就很容易鬆開。

A direct translation from English, the Surgeon's Knot is indeed a surgical knot. It gets its name from its use in surgical sutures. However, another knot, the double-strand straight knot, also shares this name, which can be confusing.

This knot is derived from the square knot; to tie it, simply wrap the two strands of the square knot around the rope an extra time. Its characteristic is that it's difficult to untie due to increased friction. It's useful when using thick, easily loosened ropes. Even with the two strands intertwined, it remains tight and is often used to secure things. Like the square knot, reversing the order of the crossing strands creates a vertical knot, significantly reducing its strength, so caution is advised.

When using a thin rope, the two strands can be wrapped several times, but the number of wraps when crossing the ends should be the same as usual. However, this method has the disadvantage of increasing the knot's volume, making it easier for gaps to form between the two strands, especially with very thin ropes (below size 2), which can easily loosen.

基本繩結 - 防脫結 及 8字結 Stop Knot / Overhand Knot / Figure of Eight Knot / Titiwa

基本繩結 - 防脫結 及 8字結  Stop Knot / Overhand Knot / Figure of Eight Knot / Titiwa 「防脫結」和「8字結」都是以結頭防止脫落的基本繩結，其實，釣友們在製作釣組時，所使用的繩結大多都是由這兩種繩結變化而來。 只要一看圖就可以了解，「防脫結」（Stop Knot／Overhand Knot）是日常生活中經常使用的結。只要把纏繞的圈數增加為2圈就成為「固定式防脫結」；在繩圈裡穿過一條線繩就成了「電車結」，如果再增加纏繞的圈數而且附上釣鉤，就變成「內掛結」。一次用兩條繩子綁，又變成(Surgeon's Knot）。 「8字結」（Figure of Eight Knot）是製作titiwa（用8字結做成的繩圈）等不可缺少的熟悉繩結，如果再增加纏繞旳圈數並附上釣鉤，就成了「外掛結」。用在轉環結的「抱緊結」也是以這個結為原型，相信只要看圖就能一目瞭然。 Both the "Stop Knot" and the "Figure-Eight Knot" are basic knots used to prevent the knot from coming undone. In fact, most knots used by anglers when making fishing rigs are variations of these two knots. A quick look at the diagram is enough to understand that the "Stop Knot" (also known as the "Overhand Knot") is a commonly used knot in everyday life. Increasing the number of wraps to two creates a "Stop Knot"; threading a line through the loop creates a "Tram Knot"; further increasing the number of wraps and ad...

基本繩結 - 稱人結 Bowline

基本繩結 - 稱人結 Bowline 稱人結的英文是「Bowline」，此外又名「繩結之王（King of Knot）」。由此可見這個繩結的強度之高以及用途之廣了。日文稱為「舫結」，因為這個繩結原本是停泊船隻時所用，意思和英文名稱的Bowline相同。 它並非只是個強度很優秀的繩結。最大的優點是即使被水淋溼，也能夠輕易解開。正因如此，才會廣泛地應用在船隻的停泊、海邊和河川等水上作業。和英國人結一樣，可以纏繞在柱子等物體上再做出繩圈，因此繩圈的大小可以自由調整，這也是它廣獲好評的理由之一。 對不必鬆綁的釣組而言，雖然這個繩結幾乎無法派上用場，不過卻可以用來綁水桶、魚簍、魚串等釣魚配件；從高山把東西運上運下的時候，也可以發現這個繩結的蹤影。因為這也是製作逃生繩索時定會用到的繩結，最好還是要熟記它的打法。 The English name for this knot is "Bowline," and it's also known as the "King of Knots." This demonstrates its high strength and wide range of uses. In Japanese, it's called "Hōmiki," because it was originally used for mooring boats, and its meaning is the same as the English name "Bowline." It's not just a knot with excellent strength. Its greatest advantage is that it can be easily untied even when wet. This is why it's widely used for mooring boats and for water operations such as those at sea and in rivers. Like the English knot, it can be wrapped around objects like pil...
