    • The present invention is directed to a utility receptacle apparatus for use with a work surface. The utility receptacle apparatus has a mounting member that has a frame which has a central opening and a peripheral portion that extends about the central opening. At least one fastening device is attached to the mounting member for attaching the mounting member to a work surface. The utility receptacle apparatus also has a base positioned within the central opening of the frame and attached to the frame. The base has a body portion and a utility receptacle member that is attached to the body portion. The utility receptacle member has a raised face that is above the top surface of the peripheral portion of the frame. At least one utility receptacle is connected to the raised face of the utility receptacle member. The utility receptacle apparatus further includes a hinge device that has first section attached to the base and a second section that pivots with respect to the first section. A cover is attached to the second section of the hinge device and pivots between a closed position and an open position. The cover has front and side portions, an exterior portion and an interior portion. The interior portion comprises a recessed interior surface that confronts the raised face of the utility receptacle member when the cover is in the closed position. The front and side portions and recessed interior surface of the cover cooperate to provide a spatial region within the interior portion of the cover that is sized to receive the entire raised face of the utility receptacle member when the cover is closed.
    • 本发明涉及一种用于工作表面的实用插座设备。 该公用插座装置具有安装构件,该安装构件具有框架,该框架具有围绕中心开口延伸的中心开口和周边部分。 至少一个紧固装置附接到安装构件,用于将安装构件附接到工作表面。 该公用设备插座设备还具有位于框架的中央开口内并附接到框架的底座。 基部具有主体部分和附接到主体部分的公用插座部件。 公用插座构件具有在框架的周边部分的顶表面上方的凸起面。 至少一个公用插座连接到公用插座构件的凸面上。 该实用插座设备还包括铰链装置,该铰链装置具有连接到基座的第一部分和相对于第一部分枢转的第二部分。 盖子连接到铰链装置的第二部分并且在关闭位置和打开位置之间枢转。 盖具有前部和侧部,外部部分和内部部分。 所述内部部分包括凹陷的内表面,当所述盖处于所述关闭位置时,所述内表面面对所述公用插座构件的凸面。 盖的前部和侧部以及凹入的内表面协作以在盖的内部部分内提供一个空间区域,该空间区域的尺寸适于当盖子关闭时接纳整个公用插座构件的整个凸面。
