People are not used to noticing everyday little things. Some knowledge comes over the years, something is learned during study or brings life experience. To know the name of a zipper dog, knowledge is not needed. In fact, the runner has a definition; even the tail, by which you have to move the dog, has a name. What is the actual name of an object that moves along long connecting fittings?
What is the correct name for a zipper closure?
Important! The zipper has received many names: slider, slider and “dog”.
To understand what the “dog” means, you need to know the concept and structure of lightning.
Definition
Lightning, aka zipper - fabric strip consisting of two strips. Sewn onto opposite parts of clothes, shoes, bags, and other things.
The main purpose – quick connection of two fabric and leather parts. Each tape has links in a checkerboard pattern.The links can be separate elements made of different materials, or they can be rings of the same spiral.
In order for the connection and separation of parts to occur, there is a special device between the tapes that moves along the zipper. The runner slides along the belts, catching the teeth on both sides so that one of them is between the two on the opposite side.
What is lightning made of?
The main parts of the fastener are:
- two strips of thick braid;
- slider limiters;
- puller - a hanging keychain on a slider;
- free edges on the braid;
- a pin inserted into a detachable stopper with a socket;
- edge clamp or sealing tape;
- links.
Depending on this structure, a different definition can be given - two braids sewn into clothing are connected by a slider, on which, for convenience, there is a puller (a free part of the lock, which the owner of the clothing grabs with his hands to close the zipper). To prevent the slider from jumping off, the zipper has a sealing tape at the bottom and a slider stop at the top.
This design facilitates the process of fastening jackets, windbreakers, bags, boots, pockets, trousers. Today, zippers are actively used to decorate items of clothing and other items.
History of lightning
History shows that the creation of many objects and devices is random. That is, a man was sitting and suddenly it came to mind, shouldn’t he? The same thing happened with the zipper.
The history of the zipper is very interesting. Several developers worked on it at once.
- In 1851, American Elias Howe, who invented a sewing machine, first brought to life the idea of quickly fastening clothes using a special device.But his patent was not approved, and the lightning did not find a response from the people.
- In 1870, a certain American citizen Style was forced to implement Leo Judson's design. During a fire, he injured his back, and to make life easier, without having to bend over to tie his shoelaces, he asked his friend Leo to come up with a fastener that could be fastened with one hand. This development is not plagiarism, but a completely new design that served as a prototype for the modern zipper. But only a patent was registered in 1981 on a shoe fastener.
These two stages in history served as prerequisites for the fruitful development and promotion of zippers among the masses. The first mention of the design was not accepted due to the illiteracy of mankind. They couldn't use the fittings. When the second American launched an entire factory for the production of zippers and provided them with instructions, from that moment it is generally accepted that the existence of the zipper, zipper, and clasp began to exist.
Popularity and demand Zipper (translated from English as zipper) was received in 1923. An interesting definition came to the mind of Bertram Rock, a shoe manufacturer. He liked the sound made when the zipper closed, which is why the zipper was nicknamed the zipper.
Types of lightning
There are several types of fasteners. They are divided according to the type of prong and the method of sewing into clothing. Let's look at what they are depending on the type of teeth:
Spiral (twisted) clasp
This type of fastener consists of modified teeth, like turns of one spiral. The material for them is synthetic fiber. They are sewn to the edges of the braid so that a checkerboard pattern is formed, which is necessary for easy fastening and unfastening.
It is considered an impractical zipper, since during the actions performed with it, the sewn threads and braid fray, due to which the spiral is completely torn off. There is no way to fix the problem.
Tractor
Got the name due to external resemblance to tractor tracks. It has fairly large links, located separately on the braid, not connected to each other, but securely attached to the braid. If several teeth are lost, the zipper does not lose its functions.
Separate the cloves are made in the shape of some kind of fungus, having a thin cap, a thickened stem, and a groove, thanks to which the teeth are firmly connected to each other. The main area of use is outerwear, as it requires the most stable fastener.
Metal
The structure of the zipper is similar to that of a tractor. Has separate teeth made of metal wire. The metal can be nickel or brass. The practicality of a fastener is measured by the number of movements performed with it. The more there are, the more the teeth wear out. The upper part wears off and the zipper begins to jam.
Other varieties
Depending on the method of attachment to clothing, the functions of zippers are:
Secret
The teeth of such a clasp are not visible outwardly; they are sewn so that part of the braid covers them on top. Used to prevent the fastener from being visible on clothing: for evening dresses, skirts, trousers.
With its help you can solve the problem of the lack of similarity between the fastener and the fabric in color. It is sewn in so that only a narrow puller is visible from the outside.
There are especially strong hidden structures, the tightness of which prevents moisture from penetrating under clothing. They are used for sewing protective waterproof suits.
Detachable and non-detachable
In simple words: detachable zippers are those that, when opened, are divided into two bands. This happens due to the presence at the bottom of a detachable stopper with a socket into which a pin from another braid is inserted, and then the fastener is closed. Suitable for outerwear, sweaters, dresses, dressing gowns.
One-piece fasteners have slider stops on top, and they are sewn in such a way that the lower part of the zipper does not open. Used for trousers, skirts, boots, bags, wallets, sweaters.
With protection against unfastening
This function is performed special metal spikes on the slider located below. When connecting the links, they fall between them and prevent the spontaneous opening of the entire structure. We can say that with the help of them the position of the slider is fixed.
In addition to those presented, there are two-way zippers, which have two sliders on one strip. With their help, the product can be opened and closed from the bottom and top. There are many classifications of zippers; they are used by seamstresses and shoemakers, as well as haberdashery sewers.
Having studied the history of the origin of zippers, their structure and types, it can be argued that they make a person’s life much easier and give clothes a certain look than with buttons, hooks, ties, etc. Having studied the material, any woman can say affirmatively: “I know, What is the name of the “dog” on the zipper?
