[Solution] The outlet cover 1 is composed of a cover body 11 with a plug projection 114 protruding from it, and a lever 12 having a hook 124 and an extrusion projection 122. When the hook 124 is pulled up, the lever 12 rotates approximately 90 degrees around the fitting cylinder 115, and the extrusion projection 122 contacts the outlet surface 21 and pushes out, making it easier to remove the plug projection 114 from the outlet insertion hole 22.

Description

Technical Field

[0001] The present invention relates to a power outlet cover that is used to block the insertion holes of a power outlet plug and is easy to remove.

Background Art

[0002] When the power outlet plug is not inserted, the insertion holes of the plug are exposed. If this state is left unattended, there is a risk that foreign objects will enter the insertion holes of the plug and cause a short circuit, or that a child will insert a foreign object into the insertion holes of the plug and get an electric shock. To prevent these risks, a power outlet cover that blocks the insertion holes of the power outlet plug is used. The most common power outlet cover has a structure in which protrusions that are inserted into the insertion holes of the plug protrude from a base that is large enough to hide the insertion holes of a pair of left and right plugs, and is made of an insulating material such as resin or rubber.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Standard electrical outlets have a spring mechanism that grips the plug blades and conducts electricity. Therefore, when the protrusions on the outlet cover are inserted into the plug's insertion hole, the spring mechanism inside the outlet grips the protrusions tightly, making it difficult to remove the cover. In addition, typical outlet covers have a thin base that covers the insertion hole, and the surface area on the sides that can be gripped with a finger is small, making it difficult to apply force and increasing the risk of finger injury when removing the cover.

[0005] Therefore, if a protrusion is added to the opposite side of the outlet cover's base from the side with the protrusion that inserts into the plug hole, it becomes easier to hook a finger onto it and apply force, thus making it easier to pull out the cover. However, such a structure makes it easy for anyone, including toddlers, to pull it out, and therefore it cannot completely prevent electric shock from toddlers tampering with outlets, which is one of the purposes of using outlet covers. Therefore, we conducted research to develop an outlet cover that cannot be easily pulled out by toddlers, but can be easily pulled out by adults. [Means for solving the problem]

[0006] The outlet cover 1 of the present invention consists of a cover body 11 formed with a plug projection 114 for insertion into an outlet insertion hole 22, a fitting cylinder 115 for fitting into a fitting hole 121 when attaching the lever 12, and a retaining projection 116 that holds the lever 12 so that it cannot be easily pulled up when the lever 12 is stored in the cover body 11, and a lever 12 formed with a fitting hole 121 that fits into the fitting cylinder 121 of the cover body 11, a retaining recess 123 that fits into the retaining projection 116 of the body 11, a hook 124 for hooking a fingernail when pulling up the lever 12, and an extrusion projection 122 that contacts the outlet surface 21 when the lever 12 is pulled up.

[0007] When the lever 12 is pulled up, the lever 12 rotates approximately 90 degrees around the fitting cylinder 115 formed on the cover body 11, and the push-out projection 122 contacts and pushes out the outlet surface 21, causing the plug projection 114 to slightly dislodge from the outlet insertion hole 22. Therefore, a great deal of force is not required to pull the outlet cover 1 out of the outlet 2.

[0008] When the plug projection 114 is slightly pulled out of the outlet insertion hole 22, a gap is created between the outlet surface 21 and the cover body 11. By hooking a finger into this gap, it becomes easier to apply force and pull out the outlet cover 1 from the outlet 2.

[0009] When the lever 12 is stored in the cover body 11, the retaining projection 116 formed on the cover body 11 fits into the retaining recess 123 formed on the lever 12, preventing the lever 12 from being easily pulled up. [Effects of the Invention]

[0010] The outlet cover of the present invention has a cover body with a projection that is inserted into the insertion hole of the outlet, and a pivotable lever centered on a fitting cylinder. By pulling up the lever, the pushing projection of the lever comes into contact with the surface of the outlet, and by pushing it out using the lever principle, the plug projection comes out slightly from the insertion hole of the outlet, making it easier to pull out the outlet cover. At the same time, a gap is created between the outlet cover and the outlet, so it is easier to apply force when pulling the outlet cover out of the outlet by hooking your finger into this gap.

[0011] When the outlet cover is inserted, the lever is retracted into the cover body, and the retaining recess of the lever engages with the retaining protrusion of the cover body, making the lever inconspicuous and preventing it from being easily pulled out. As a result, the outlet cover of the present invention requires little force to remove and cannot be easily pulled out by young children. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0013] The mode for carrying out the present invention will be described with reference to the drawings. As shown in FIG. 6, the socket cover 1 of the present invention is composed of a cover main body 11 that is inserted into the socket 2 and a lever 12 that is attached to the cover main body 11.

[0014] On the cover main body 11, an inclined surface is formed at the boundary between the front surface, that is, the surface opposite to the surface in contact with the socket plane 21, and the outer peripheral surface, and it is hollow along the outer shape. Also, on the front surface, there is an incorporation hole 111 for incorporating the lever 12 into the cover main body 11.

[0015] The vertical ribs 112 are formed along the mounting holes 111 on the back to increase the strength of the cover body 11, and the horizontal ribs 113 are formed between the two vertical ribs 122.

[0016] The vertical rib 112 is formed along the mounting hole 111 on the back of the cover body 11. A plug projection 114 is formed on the vertical rib 112 perpendicular to the surface that contacts the outlet plane 21, and can be inserted into the outlet insertion hole 22. In addition, a fitting cylinder 115 is formed in the center of the vertical rib 112, which fits into a fitting hole 121 formed in the lever 12.

[0017] The transverse rib 113 is formed between the two longitudinal ribs 112, increasing the strength of the cover body 11. The transverse rib 113 also has a retaining projection 116 that holds the lever 12 in place so that it cannot be easily pulled out when the lever 12 is stored in the cover body 11, and this projection fits into a retaining recess 123 formed on the lever 12.

[0018] The lever 12 has a curved shape that follows the slope formed at the boundary between the front and side surfaces of the cover body 11, and has a fitting hole 121 that fits into the fitting cylinder 115 of the cover body 11. The fitting cylinder 115 is also the center of the lever 12, and the lever 12 is composed of a hook 124 for the claw to hook when pulling up the lever 12 and an extrusion projection 122 that contacts the outlet surface 21 and pushes it out when pulled up.

[0019] When installing the outlet cover 1 to the outlet 2, insert the left and right plug protrusions 114 into the corresponding left and right outlet insertion holes 22, and push the cover body 11 in until it contacts the outlet surface 21. Then, engage the retaining protrusion 116 of the cover body 11 with the retaining recess 123 of the lever 12 to prevent the lever 12 from being easily pulled up.

[0020] To remove the outlet cover 1 from the outlet 2, hook your finger onto the hook 124 formed on the lever 12 and pull up the lever 12. When the lever 12 is pulled up, the retaining projection 116 of the cover body 11 and the retaining recess 123 of the lever 12 are disengaged, and the lever 12 swings approximately 90 degrees around the fitting cylinder 115, causing the push projection 122 to contact the outlet surface 21 and push out, causing the plug projection 114 to slightly come out of the outlet insertion hole 22. At this time, a gap is created between the cover body 11 and the outlet surface 21, so by putting your finger into this gap and pulling the cover body 11, the plug projection 114 comes out of the outlet insertion hole 22, and the outlet cover 1 is removed from the outlet 2.
