Description

  The present invention relates to an outlet cover that covers a front side of a plug outlet of an outlet.

If the outlet plug outlet is left unused and left exposed, fine dust may enter the outlet from the plug outlet, or dust may form around the outlet of the plug outlet on the outlet surface. There is a possibility of adhering and depositing, and if it is left as it is, there is a problem of inducing a tracking phenomenon.
Therefore, conventionally, as shown in Patent Documents 1 and 2, for example, there has been proposed an outlet cover that covers the front side of the plug socket when the outlet is not used. In this outlet cover, a protrusion that can be inserted into a plug insertion port of the outlet is integrally formed on one side of a plate-like cover body having electrical insulation.
The area other than the part where the protrusion is formed on one side of the cover body is a smooth surface that is in contact with or close to the surface of the outlet when the protrusion of the cover body is inserted to the maximum outlet position with respect to the plug insertion port of the outlet. It is configured. Furthermore, the other side surface of the cover body is also a smooth surface.

Since the form arranged on the side wall surface of the place is adopted, it is difficult to grasp the peripheral side surface of the cover body in contact with or close to the surface of the outlet, and it is easy to take time and effort by removing the outlet cover.

  In view of this situation, the main problem of the present invention is to quickly remove the cover body inserted and attached to the plug insertion port even when the outlet is disposed on the side wall surface of the spatially restricted place. It is in providing an outlet cover that can be easily performed.

  According to a first characteristic configuration of the present invention, an electrically insulating protrusion that can be inserted into a plug insertion port of an outlet is formed on one side surface of a plate-like cover body, and a finger hook portion is formed on the other side surface of the cover body. Is in the point provided.

According to the said structure, when the protrusion of a cover body is inserted and installed in the plug insertion port of an outlet socket, intrusion of dust, water, etc. to the plug insertion port can be prevented by the cover body and the protrusion.
Moreover, when resuming the use of the outlet, when pulling out the outlet cover that is plugged into the plug insertion port, it is a simple operation to hang your fingers on the finger rest provided on the other side of the cover body, The pulling force can be accurately and easily applied to the cover body.
Therefore, even when the outlet is disposed on the side wall surface in a spatially restricted place, the cover body can be quickly and easily removed by finger operation.

  According to a second characteristic configuration of the present invention, the finger-hanging portion is configured to be freely changeable between a finger-hanging posture protruding outward from the other side surface of the cover body and a storage posture along or substantially along the other side surface of the cover body. It is in the point.

According to the above configuration, in a state where the protrusion of the cover body is inserted into the plug insertion port of the outlet, the finger resting portion is placed in a retracted position along or substantially along the other side surface of the cover body, thereby The amount of overhang is reduced and the outlet cover can be stored compactly.
Still, when pulling out the outlet cover that is plugged into the plug insertion port, change the finger hanging part in the retracted position to a finger hanging attitude that protrudes outward from the other side of the cover body. It can be easily operated with fingers.

  According to a third characteristic configuration of the present invention, the finger-hanging portion is pivotally supported by a mounting portion provided on the cover body so as to swing up and down around a horizontal axis, and the hanging posture due to the weight of the finger-hanging portion is stored. The point is that the posture is configured.

  According to the above configuration, when the finger is released from the finger-hanging portion that protrudes outward from the other side surface of the cover body, the finger-hanging portion swings to the hanging posture by its own weight around the horizontal axis core to the retracted posture. Since the change is made, the operation for changing the finger-hanging portion to the retracted posture can be performed reliably and easily.

  A fourth characteristic configuration according to the present invention is that when the finger-hanging portion is in the retracted position, a gap is formed between the finger-hanging portion and the other side surface of the cover body.

  According to the above configuration, when changing the finger-hanging position by placing a finger on the finger-holding part in the retracted position, the finger-holding part is positioned on the front side by the gap formed between the other side surfaces of the cover body. become. Thereby, it becomes easy to place a finger on the finger-hanging portion, and a change operation to the finger-hanging posture can be easily performed.
