Abstract

(57) [Summary] [Purpose] To make it easier to carry the cords and extension cords that come with electrical appliances, to handle the cords after use, and to tie them up quickly. Avoid cutting the core wire (copper wire) at the base of the wire. [Structure] In order to memorize the internal material of cords attached to electrical appliances and extension cords and the shape of the entire cord in a specified shape, materials such as thermoplastic elastomer are used as the protective covering material of the cord, and shape memory Alloys and spring steel are also put into the cord together with the core wire (copper wire) to form the cord, and the cord memorizes a shape that allows the cord to be easily bundled.
Even if the cord is stretched or pulled, it will elastically return to its original memorized shape.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

Conventional electric appliances have cords that are a big hindrance when carrying them around when they are in use. It is troublesome to bundle, and manufacturers often incorporate cords into the equipment at the manufacturing stage. However, there were problems such as not adopting it because the market price would be high. According to this invention If the cord of the appliance is unplugged from the outlet immediately after use, the cord will It almost returns to its pre-memorized shape, and you can carry it with just a little help from your hand. The result is a bunch of cords that don't get in the way. The cord of this invention can be connected to the equipment. Unlike automatic winding methods, it can be manufactured at a very low cost and is easy to carry. Not only is it convenient, but it also prevents the cord from getting caught when storing or carrying it. This also has the effect of preventing the core wire (copper wire) of the cord from breaking.

[Conventional technology]

When cleaning up cords attached to conventional appliances and outlets with extension cords , If the cord comes with a band to tie it, tie the cord several times to the appropriate length and width. They also had to be folded and tied by hand. And it comes with a belt to tie it together. If the cord is too thick, bring a rubber band or wire and bend the cord several times by hand. I had to pull myself together. There is also something called curl cord on the market. However, it was still the same as before, just shorter.

0003

[Problem that the invention is trying to solve]

It is difficult to bundle the cords attached to conventional electrical appliances unless they are equipped with an automatic winder. It was very troublesome. It is called a helical-shaped curl cord that is commercially available. Although the cord is shorter, it still dangles around, and there is an automatic winder built into the device. A board would be ideal, but the manufacturing cost would be too high and it would be difficult to integrate it into the appliance. However, do not use the power cord for products that generate high heat inside the main unit, such as hair dryers, irons, and toasters. There are problems with having a built-in card, so it is currently not being used. Also, the equipment The base of the cord of the appliance or the base of the plug may be hung while carrying the cord. The disadvantage was that the core wire (copper wire) was easily cut.

[Means to solve the problem]

The means to be solved by the present invention is the "scope of utility model registration claims" in the specification of the present invention. The problem is solved by means of the matters stated in "Claim 1" to "Claim 7" of Ru. The types of shapes are "Figure 3. Figure 4" shape, "Figure 5. Figure 6" shape, and "Figure 7. Figure 8" shape. ．． There are three types of shapes shown in Figure 9, and the method of memorizing the shape in the code is to use thermoplastic resin. Processing method using lastomer and shape memory alloy or spring steel etc. inside the cord A method that mixes these two methods, and a method that uses thermoplastic elastomer. The problem can be solved using four methods: using wire that is plastic at room temperature.

[0005]

[Effect]

By various types of means of this invention, electrical appliances and extension cords can be When cleaning up, it is difficult to clean up if the cords are hanging around. Electrical appliances and extensions When you unplug the card from the outlet, the preset memory settings will be reset. It returned to a shape close to the state of It has the convenience of becoming elastic in shape, and it relieves you from tedious work.

Ru. Figure 2 shows that the cord of the present invention in Figure 1 is made of stretched material such as shape memory alloy or spring steel. Reference for cords with built-in metal that elastically return to their original shape even if they are bent or twisted. It is a diagram. (4) is shape memory alloy or spring steel. Figure 3 shows the cords shown in Figures 1 and 2, bundled together with a suitable length and width, and hold both ends with your hands. This is a reference diagram of a method in which the material is processed into a twisted shape. Figure 4 shows the shape of the cord shown in Figure 3 when it is unfolded, stretched, and used. This is a reference drawing in which the memorized shape remains. Figure 5 shows the cords in Figures 1 and 2, with most of the cords tied up properly and the remaining plugs A reference to the method in which a small part of the side was wrapped around the bundled cord. It is a diagram. Figure 6 shows the shape of the cord shown in Figure 5 when it is unfolded, stretched, and used. This is a reference drawing in which the memorized shape remains. Figure 7 shows the cords in Figures 1 and 2, with most of the cord bundled into a loop and the remaining A small part of the lug side is wrapped around the bundled cord. This is a reference diagram. Figure 8 shows the shape of the cord shown in Figure 7 when it is used after being stretched out. This is a reference drawing in which the shape stored in . Figure 9 shows how the cords in Figures 1 and 2 are bundled into a rectangular shape with most of the cords bundled into a rectangular shape. A small part of the lug side is wrapped around the bundled cord. This is a reference diagram. Figure 10 shows the shape of the cord shown in Figure 9 when it is stretched out and used. This is a reference drawing in which the memorized shape remains.

[Effect of the idea]

As explained above, according to the present invention, after using electrical appliances and extension cords, How far should I bend the bundle and what size should I make the loop? I was having a lot of trouble figuring out if I should tie it up. Also, if the cord does not have the bundled belt that comes with it, I had to bring rubber bands and wire to tie things together. However, this idea That hassle is completely eliminated, and the cords of electrical appliances and extension cords can be plugged in and plugged in easily. The moment you unplug the rug from the outlet, it will be in a bundled state, and you will have to help it with your hands for a little while. Just by doing this, you can create a solid bundle of cords. The cord dangled again. When I tried to clean it up, I pulled the base of the appliance or plug and pulled out the core wire (copper wire) inside the cord. ) will no longer be necessary.
