Patent number: 6300570Abstract: A portable multi-outlet assembly with turnable eave. The assembly is equipped with an eave engaged to the face plate of the multi-outlet assembly with two set buttons set on respective eye holes provide at both sides of the ave so as to make the eave turnable in two semi-circular slots formed at both sides of the eave. Moreover, the movement of the eave is so arranged that it is turnable upward up to 180° until the button claw mate with the stoppers in two slots of the eave. At this time the operator is able to insert plugs into the outlets at a most ergonomically comfortable direction of 45° inclination. The multi-outlet assembly can be set on the ground by a bayonet-shaped post with the face plate of the assembly parallel to the ground such that the inserted plugs can also be shaded by the eave thereby preventing entry of rain water into the multi-outlet assembly.Type: GrantFiled: January 5, 2001Date of Patent: October 9, 2001Inventor: Li-Chun Lai

Patent number: 6281440Abstract: A decorative article for mounting about a wall mounted electrical cover plate of a switch or receptacle includes a frame having an inner periphery smaller than the cover plate and an outer periphery larger than the cover plate. The inner periphery defines a central opening. The frame includes a channel extending outwardly of the inner periphery. The channel has a depth substantially equal to the thickness of the cover plate and the channel has an outer periphery substantially the same size as the cover plate. The frame is thus capable of surrounding the cover plate with the switch or receptacle being accessible through the central opening. An adhesive strip is affixed to the frame so that the frame may be adhered directly to the wall around the cover plate or to a back plate positioned between the cover plate and the wall. The back plate has an inner periphery smaller than the cover plate and an outer periphery larger than the cover plate.Type: GrantFiled: March 18, 1999Date of Patent: August 28, 2001Assignee: Jackson Deerfield Manufacturing CorporationInventors: Reginald A.
