The present invention can accommodate multiply plugs in different shapes, connect to a power supply wire as extension cord for either construction or household by user and have an earth lip at the surface for receiving the German or French plugs with earth connection for advantages of reducing inventory and industrial application of non-permanent sockets.

Abstract: The present invention is related to a multi-functional bed apparatus with a back support, comprising a head supporting pad, a neck supporting pad attached to one side of the head supporting pad, a waist supporting pad movably attached to the head supporting pad and a hip supporting pad movable attached to another lateral side of the waist supporting pad away from the head supporting pad; wherein the neck supporting pad comprises an arched portion adjacent to a lateral side of the waist supporting pad. The user can alter the curvature between any one of the pads such that the bed apparatus conforms to human ergonomics of an ergonomic bed or chair for the user body. The arched portion further provides adequate support to the arms of the user to prevent arm muscle pains. Therefore, the present invention is applicable to various fields and uses with simplified operations and great comforts.

Abstract: The universal plug adaptor contains a face plate and a casing joined to the face plate. The casing contains a first track element, a terminal set, two platform elements, and a first sliding element in the casing. Each platform element has a first limiting piece for locking the first sliding element when it is pressured from a side. The platform elements, the first tack element, and the first sliding element engage with each other. The universal plug adaptor is able to prevent the hazard when only a prong is inserted and a prong is left outside the universal plug adaptor, and the first ground piece allows proper grounding to plugs conforming to German and French specifications.

Abstract: A safety plug adapter comprises a cover, a base plate, a conductive terminal block, a first sliding assembly, a second sliding assembly, two first conductive pins, two second conductive pins, two auxiliary elements, a ground portion, a grounding terminal block, and an attachable conductive pin, wherein the cover defines a first group of slots on a top surface thereof and a second group of slots on a side surface; the first group of slots includes a live slot, a neutral slot, and a ground slot; the second group of slots includes a live slot and a neutral slot. With the plug adapter, the first group of slots or the second group of slots can be inserted by a plug of an electrical device, whereas the first conductive pins or the second conducive pins can insert into a socket, to achieve an electrical connection between the electrical device and the socket.

Abstract: The universal plug adaptor contains a terminal set for contacting plug pins housed between a face plate and a casing. The face plate contains a number of sets of plug holes. A first hole set contains a first live hole, a first neutral hole, and a first ground hole conforming to the South Africa specification. A second hole set contains three separate openings, each containing a number of plug holes for ground pins of various specifications. A third hole set contains two plug holes conforming to global 250V specification with two flat pins or two round pins. A fourth hole set contains two plug holes conforming to America 125V specification's two flat pints or two round pins. And a fifth hole set contains two plug holes conforming to America specification with two flat pins. The third and fourth hole sets jointly provide two plugs' simultaneous plugging.

Abstract: A longitude/latitude ten-dimension XYZ digital-displaying spectrometer includes an imaging device combined with the digital-displaying spectrometer to work with a Z axis position processing unit and a coordinate processing unit and arranged in information connection with a plurality of displaying elements to allow of calculation of Z0° in horizontal of East, West, South, North, and the circumference with respect to the horizontal level of the compass through the combination of the imaging device with the processing units and displaying of the angles through the displaying elements, so as to provide an improvement of precise reading of the angles in the ten dimensions.

Abstract: A multi-functional wiring plug converter is provided. The converter is mainly composed of a case, connection guiding assemblies and a panel cover. A plurality of setting areas defined by the case are respectively used for installing and fixing the connection guiding assemblies, and each connection guiding assembly is composed of a connection guiding seat, a connection guiding clamp sheet and a wire-locking fixed block. A blocking portion extending from the connection guiding seat forms a plurality of fixed portions, and each fixed portion is used for fixing the connection guiding clamp sheet and the wire-locking fixed block. Therefore, when a power wire needs to be connected, it can be directly locked onto the wire-locking fixed block so that the power wire is fixed in the converter, and the converter can be sold to any region and additionally provided with a connection guiding panel which conforms to specifications of the region.

Abstract: A multi-functional polarity-correcting plugging-coupling switching device includes a rotary component, which is rotatable and has at least one inspection element that is electrically connected to a touch control resistor and a live connection of a power plug. With a user using a hand to touch the touch control resistor, a closed circuit is formed with the human body for identifying correct position of polarization of the power plug. Further, through rotation of the rotary component, correct polarization and voltage level can be selected. Further, a resistive indicator is provided for indicating correct connection of earth line.

Abstract: The electrical adaptor contains a casing having a receiving indentation. Two corresponding positioning notches are provided, respectively, along two opposing lateral side walls of the receiving indentation. Inside the receiving indentation, there are two prong holes, each having an electrical contact inside. A first ground piece is tightly embedded into a front notch along a front wall of the receiving indentation. An additional second ground piece is provided along a back wall of the receiving indentation, opposing the first ground piece. When a German- or French-style plug is plugged, its two positioning ribs on the lateral sides are received by the positioning notches, respectively, and its ground pieces in the front and back are received by the ground notches. In the mean time, its prongs are received by the prong holes and contacted by the electrical contacts, respectively.

Abstract: A German/French style plug with multiple pin arrangements includes an outer enclosure, an inner housing, a stop plate, a constraint plate, and multiple plugging units. The plugging units are received in the outer enclosure and the inner housing. To move the plugging units, the constraint plate is first displaced to free the plugging units. The plugging units have operation pegs that are operable to have pins of the plugging units projecting out of through holes defined in the outer enclosure or through openings defined in the inner housing. The second plugging unit has a constraint section that is movably received in a constraint slot defined in the inner housing, whereby the movement of the second plugging may cause extension of the inner housing to form a stepped configuration to provide an additional plug structure for different socket specifications.
