Abstract: An electric outlet safety plate incorporates sliding cover elements which, in various positions, cover the electric outlet when not in use, open for insertion of an electric plug, and grasp the plug to prevent removal. A plate member includes a groove extending outwardly to the side from each of the electric outlet openings. A pair of substantially identical sliding members engage the groove from opposing sides of the plate member. The sliding members include an outlet covering portion which is spaced from the outer surface of the electric outlet and has its inner edges toothed to enhance their grasp upon the electric plug. The sliding members are lockable against outward movement on the plate member. Teeth are formed upon the plate member so as to extend within the groove, and a second set of teeth are formed upon the sliding member so as to releasably engage the teeth of the plate member. The sliding member teeth are formed upon a resilient arm which is biased to engagement, but may be disengaged by finger pressure. Where the plate member teeth are formed on both sides of the groove and the sliding member teeth are formed on each of a pair of resilient arms thereon, release occurs by pressing the two arms towards each other. A ratchet tooth structure may be used to allow direct inward movement of the sliding members, but which requires disengagement to move the sliding members outwards toward the uncovered position.

Abstract translation: 电气插座安全板包括滑动盖元件，其在不使用时在各种位置覆盖电源插座，打开以插入电插头，并且抓住插头以防止移除。 板构件包括从每个电气出口开口向外延伸到侧面的凹槽。 一对基本相同的滑动构件从板构件的相对侧接合凹槽。 滑动构件包括与电气出口的外表面间隔开的出口覆盖部分，并且其内边缘是齿形的，以增强其在电插头上的把握。 滑动构件可抵抗板构件上的向外移动。 牙齿形成在板构件上，以在槽内延伸，并且第二组齿形成在滑动构件上，以便可释放地接合板构件的齿。 滑动构件齿形成在弹性臂上，该弹性臂被偏置成接合，但是可以通过手指压力而脱离。 在板构件齿形成在槽的两侧并且滑动构件齿形成在其上的一对弹性臂的每一个上时，通过将两个臂相互按压而释放。 可以使用棘轮结构来允许滑动构件的直接向内运动，但是这需要脱开以将滑动构件朝向未覆盖位置向外移动。
