Description

  The present invention provides a plug body for a power source in an electrical device, or a plug body that is attached to the plug body even in an unstable state where the outlet on the power source side is not fixed like an extension cord or the like. The present invention relates to an outlet plug that can be easily pulled out with one hand and an auxiliary tool for the outlet plug.

Conventionally, when using electrical equipment, the plug body on the electrical equipment side is inserted into a power outlet provided on the wall surface, etc., but usually this plug body should be inserted and pulled out with one hand without difficulty. Can do. However, a bifurcated instrument is often used as a power outlet, and in such a case, if you try to pull out the plug body from the bifurcated instrument with one hand, the bifurcated instrument itself will come out together with the plug body, even if you intend to remove the plug body. It is not uncommon for other electrical equipment that uses power to cause unexpected problems. Therefore, since it is extremely difficult to pull out the plug body with one hand from the bifurcated device, in many cases it is performed with both hands.
Furthermore, when using an extension cord, the power outlet is not fixed and cannot be pulled out with one hand.
In addition, when a strong force is required to pull out the plug body, the connecting portion between the plug body and the cord may be damaged.
Thus, although many technologies have been filed to solve the above problems, most of the technologies lack practicality, and these technologies are not utilized. In the rare commercialized technology, everything is in the form of an adapter, the method intervenes as an independent instrument between the power outlet and the plug body, and the structure is for removing the plug body In addition to the necessary configuration, the structure is complicated with both male and female electrodes.
Therefore, there is no one that does not have the male and female electrodes and is attached to the plug body or is integrally formed with the plug body including mold processing to solve the above-described problems.

  The auxiliary tool for the outlet plug according to the present invention is a plug body inserted in any power outlet, and is intended to be easily removed with one hand. A hinge-like arm is provided via a holding part.

  According to the power plug adapter of Document 1, a lever using the lever principle and a pressing part connected to this lever are axially and symmetrically mounted on both sides of the adapter body, and the adapter body is inserted into a power outlet. The male electrode and a female electrode behind the male electrode are used as a power plug adapter.

  According to the plug plug cover of Document 2, the plug body is used by inserting the plug body into the main body of the plug cover, and a hole is inserted into the end of the main body and the target side of the hole is pulled with a finger. A ring is formed for the plug cover.

  According to the plug remover in Document 3, a plug remover is provided by forming a hole for inserting an electrode of the plug into the center of the dust removing type plug remover main body and forming a small ring for placing a finger on the outside of the main body. It is said.

According to the above document, the method of using Document 1 is not to directly insert the plug body into the power outlet, but first insert the plug body into the power plug adapter, and then insert the power plug adapter into the power outlet. In other words, it has a two-stage operation structure. And when pulling out the plug body, if you press the lever provided symmetrically, the member connected to this will operate according to the lever principle, and the power plug adapter body will be pushed by pushing the power outlet in the direction of pulling out the electrode. It is supposed to be extracted.
According to this document, the structure of the power plug adapter body is extremely complicated and larger than the plug body. To use this, the overall size is the length of the plug adapter body and the plug body combined. The projecting width increases, and the possibility of the plug body falling off from the power outlet increases. In addition, it is clear that the price will become expensive, and it can be said that the power plug adapter of this design is not widely used although it is currently sold.

  Next, according to Document 2, the entire body of the plug plug cover is integrally formed. The method of using the plug plug cover is to insert the plug body into the plug plug cover so that only the electrode protrudes from the opening, It is supposed to be plugged into a power outlet. And when pulling out the plug body, it is only necessary to put a finger on the ring formed on the target side of the electrode and pull it. Compared to Document 1, this plug-in plug cover has a simplified structure and seems to be inexpensive to manufacture, but when the power outlet itself is not fixed, such as an extension cord, the plug body is pulled out with one hand. There is a fundamental problem that cannot be done.

Next, according to Document 3, all of the plug remover are integrally configured as in Document 2, and the usage method is that when the plug body is first inserted into a power outlet, the plug body electrode is passed through the plug remover. The plug body can be inserted as it is, and when the plug body is pulled out, the ring formed on the plug removal tool is put on a finger and pulled forward, so that the plug body can be pulled out according to the principle of leverage.
However, although this configuration is also different from Reference 2 in that the lever principle is used, the plug body cannot be pulled out with one hand when the power outlet itself is unstable, such as an extension cord. Further, according to this configuration, there is a problem that, after the plug body is removed, there is a high possibility that the plug removing tool will fall off the plug body.
In addition to the above documents, there are many applications for the same purpose, and there are many applications in which the lever principle is applied to extract the plug body and a female electrode is incorporated in addition to the male electrode. The invention relating to this application has a problem that the main body itself is large and the number of parts increases, resulting in an increase in the price. In addition, the configuration to be attached to the plug body cannot be pulled out from an unstable power outlet such as a bifurcated instrument or an extension cord with one hand.

  The present invention provides a slit that opens downward from the vicinity of the upper end of both side surfaces of the outlet plug and is symmetrical, the bottom surface of the slit is set to a depth that is parallel to and close to the electrode, and a hinge arm in the slit. The hinge arm is provided with a shaft stop at substantially the center, the upper end is locked to the upper part in the slit, and the lower end is fixed to the lower part of the slide tool, When the moving tool is located in the upper part of the slit, the hinge arm is configured to have a symmetrical mountain shape with the axially fixed portion at the center of the hinge arm as a vertex.
