    DESCRIPTION

    Protractor

    The present invention relates to devices whose purpose is to allow the connection of more than one device to the power grid. In particular, the present invention is related to an extension which comprises more than one outlet, in which the sockets are rotatably connected to each other.

    The known extensions usually comprise a body formed by one or more 10 pieces comprising the different sockets. Each outlet includes a housing for the plugs and receives power through a cable connected to the power supply network. These extensions are very widely used, both in the domestic sector and in other applications, such as offices or workplaces of any kind. fifteen

    There are extensions whose body is formed by several pieces joined together in a rotating way. For example, document US2014 / 0102870A1 discloses an extension consisting of several pieces comprising, each, an outlet and a housing that fits with the outlet of an adjacent piece. Around the outlet 20 a surface is arranged on which the housing of the adjacent piece is placed, defining a connection interface that is in a plane parallel to the plane of the outlet, that is to say in a plane parallel to the plane in which the housings for the plugs are located. Therefore, the configurations that the extension can adopt do not allow the orientation of the power outlets to be varied, so that the versatility of the extension is limited, in addition to the possibilities from the design point of view.

    The present invention aims to solve the aforementioned drawbacks of known extensions. 30

    In particular, the present invention discloses an extension, which has a body provided with at least two power sockets provided with housings for receiving connection plugs and which internally has means of electrical connection, and a connection cable to the power supply network. power supply with a connecting plug at the end that leaves said body, the body being formed by at least two pieces, each comprising
    the pieces at least one of said power outlets and the pieces being connected with means of relative rotation between parts, characterized in that the connection interface between two pieces is arranged in a plane perpendicular to the plane of the power sockets of said two pieces, the axis of relative rotation between pieces being perpendicular to the plane of the connection interface. 5

    Thanks to the features of the protractor object of the present invention, configurations can be achieved with the power outlets in different orientations, so that the protractor offers greater versatility for use and for design.
     10
    Preferably, the connection interface between two pieces comprises a groove in a first piece and a recess in a second piece, said recess of the second piece fitting into the groove of the first piece.

    Even more preferably, said groove of the first piece comprises a stop and said recess 15 of the second piece comprises a notch in which the stop is housed, said notch allowing the displacement of the stop during the relative rotation between the first and the second piece .

    Advantageously, the travel of the notch is 90 ° of an arc of a circle plus the width 20 of the stop, whereby the relative rotation between pieces is a maximum of 90 °. Therefore, it is not necessary that there is a special connection between the parts of the outlet since it is sufficient to use a cable with a length slightly longer than its travel between parts.
     25
    Optionally, each piece comprises a lower part and an upper part, each part of each piece comprising an inlet, the inlet of the upper part together with the inlet of the lower part defining an opening.

    Advantageously, the aforementioned incoming are semicircular, and preferably the notch has a circular trapezoid shape.

    Advantageously, the connecting cable extends from piece to piece through said opening.
     35
    In one embodiment of the invention, the pieces are in the form of a parallelepiped and comprise the connection interface on one of their side faces.

    Preferably, the extension according to the present invention may comprise parts with connection interfaces on adjacent faces, or parts with connection interfaces on opposite faces. As a consequence, a wider range of configurations is possible, such as configurations in which some parts of the outlet are elevated without being in contact with the ground.

    For better understanding, some drawings of an example of embodiment of the extension according to the present invention are attached by way of explanatory but not limitative example.

    Figure 12 shows a perspective view of a detail of the connection between two parts of the body of Figure 1.

    An embodiment of a protractor -1- according to the present invention is illustrated in Figure 1, comprising a cable -2- for connection to the power supply network and a body 5 formed by four parts -3-, -4- , -5-, -6- in the shape of a parallelepiped that are connected to each other with means of relative rotation between them. Each of the parts -3-, -4-, -5-, -6- comprises an outlet -31-, -41-, -51-, -61- to receive connection plugs that it has inside electrical connection means. In the embodiment shown in Figure 1, the sockets -31-, -41-, -51-, -61- are arranged on the upper faces of the 10 pieces -3-, -4-, -5-, -6-.

    For reasons of clarity, from now on the pieces -3-, -4-, -5-, -6- will be called first piece -3-, second piece -4-, third piece -5- and fourth piece -6 -.
     fifteen
    Thanks to the fact that the connection interface between the parts -3-, -4-, -5-, -6- comprises means of relative rotation between them, the user can alter the configuration of the extension body -1-. For example, in figure 2 it is observed how the third piece -5- and the fourth piece -6- have been placed in a position perpendicular to that shown in figure 1 by a 90º turn of the piece -5- with respect to piece -4-. However, in the configuration of Figure 1, the four pieces -3-, -4-, -5-, -6- are arranged in square, with all the sockets -31-, -41-, - 51-, -61- in the same orientation.

    The connection interface between the parts -3-, -4-, -5-, -6- is arranged in a plane perpendicular to the plane of the sockets -31-, -41-, -51-, -61- , that is, in a plane 25 perpendicular to the plane in which the housings -31'-, -41'- are located for the plugs. In the example shown, the connection interface is located on the lateral faces of the parallelepipeds of the pieces -3-, -4-, -5-, -6-, the lateral faces being found in planes perpendicular to the plane of the housings - 31'-, -41'- for the plugs.
     30
    As you can see, the first piece -3- and the fourth piece -6- are not directly connected to each other, but the fourth piece -6- is linked exclusively to the third -5- and this to the second -4- . The configuration of Figure 2 is possible because the third piece -4- comprises connecting interfaces on adjacent faces: the face of the third piece -5- which is in contact with the fourth piece -6- is contiguous to the face of the third piece -5- which is in contact with the second piece -4-.

    Other examples of possible configurations can be achieved by the relative rotation of the parts -3-, -4-, -5-, -6-. For example, the configuration of figure 3, which starts from the configuration of figure 2 and performs a 90 ° rotation of the first piece -3- with respect to the second piece -4-; the configuration of figure 4, which starts from the configuration of figure 4 5 and performs a 90 ° rotation of the fourth piece -6- with respect to the third piece -5-; or the configuration of figure 5, which starts from the configuration of figure 4 and makes a 90 ° rotation of the third piece -5- with respect to the second piece -4-. As can be seen, in each of the configurations shown, the extension -1- has power outlets -31-, -41-, -51-, -61- arranged in different planes. 10

    Figure 6 shows the parts -3-, -4-, -5-, -6- that make up the body of the protractor -1- separately and exploded. Each of the pieces -3-, -4-, -5-, -6-, comprises an upper part -32-, -42-, -52-, -62- fixed to a lower part -32'-, -42'-, -52'-, -62'-. The upper part -32-, -42-, -52-, -62- of each piece -3-, -4-, -5-, -6- comprises a recess 15 -33-, -43-, -53 -, -63- and the bottom -32'-, -42'-, -52'-, -62'- of each piece -3-, -4-, -5-, -6- comprises another entree - 33'-, -43'-, -53'-, -63'-. When the upper part -32-, -42-, -52-, -62- of a part is fixed to its corresponding lower part -32'-, -42'-, -52'-, -62'-, the starters -33-, -43-, -53-, -63- from the top -32-, -42-, -52-, -62-, together with the starters -33'-, -43'-, -53'-, -63'- of the bottom -32'-, -42'-, -52'-, -62'-, define an opening -81-, -82- (see figures 7 and 8 ) that allows the cable -2- to connect to the power supply network.

    In the embodiment of the extension -1-, according to the present invention, shown in Figure 6, it can be seen how the cable -2- extends from the fourth piece -6- to the first piece -3-25 passing over the recesses -34-, -54-, -64- of the lower parts -32'-, -42'-, -52'-, -62'- of the parts -3-, -4-, -5-, - 6-. When the upper parts -32-, -42-, -52-, -62- of the parts -3-, -4-, -5-, -6- join with the lower parts -32'-, -42 '-, -52'-, -62'-, the opening -81-, -82- (see figures 7 and 8) allows the passage of the connecting cable -2- between the pieces. In the example of embodiment shown, the maximum relative angle of rotation between parts is 90 °, 30 so no special connection is necessary for rotation to be possible. It is enough that the length of the cable -2- is slightly longer than the path that must be made between parts -3-, -4-, -5-, -6-.

    The union between the pieces -3-, -4-, -5-, -6- of the protractor -1- is carried out by fitting some pieces with others. Each of the parts of the connection are illustrated in Figures 7 and 8.

    One of the parts of the connection is shown in Figure 7, which shows the third part -5- with its upper part -52- and its lower part -52'- joined, leaving a joint -52 '' - visible between both parties -52-, -52'-. The recesses -53-, -54- define a circle-shaped opening -81- comprising a notch -55- with a circular trapezoid shape whose ends define limits -56-, -56'-.
     10
    The second of the parts of the connection is shown in Figure 8, in which the second piece -4- with its upper part -42- and its lower part -42'- joined is observed, leaving a joint -42 '' - visible between both parties -42-, -42'-. The recesses -43-, -44- are identical and semicircular, giving rise to a circular opening -82- which is surrounded by a protrusion -45- which gives rise to a groove (see figure 11). fifteen

    The third piece -5- and the fourth piece -6- are shown exploded in figures 9 and 10, in which it is observed that each of the pieces -5-, -6- comprises an outlet -51-, -61- (see figure 1) which is formed by a female housing -51'-, -61'- for the pins that are arranged at the top -52-, -62- of the part -5-, -6 -, and 20 electrical connection mechanisms -51 '' -, -61 '' - on which a piece -51 '' '-, -61' '' is placed - which also contains electrical connections. The female housings -51'-, -61'- are fixed by means of a screw -7- with an inviolable head.

    The pieces -3-, -4-, -5-, -6- are joined together by the interaction between the two mentioned 25 types of openings -81-, -82- (see figures 7 and 8). To be able to make the union between pieces -3-, -4-, -5-, -6-, these must have different opening types -81-, -82-.

    As seen in Figure 11, the projection -45- of the second piece -4- has a groove -46-. The connection between the upper parts -32-, -42- of the pieces -3-, -4- is carried out by fitting the recess -33- of the upper part -32- first piece -3- in the groove - 46- which defines the projection -45-. The groove -46- comprises a stop -47- that is housed in the notch -35- in the shape of a circular trapezoid and can move along it until it meets any of its limits -36- (see references -56- and -56'- in figure 7).
     35
    On the other hand, the union between the lower parts -32'-, -42'- of the parts -3-, -4- (not illustrated) is identical to that between the upper parts -32-, -42- of the pieces -3-, -4-, with the only difference that the slot -46- does not include any stop -47- in the lower part -32-.
     5
    Once the upper parts -32-, -42- and lower -32'-, -42'- are joined, the stop -47- can move between the limits -36- (the lower limit is not illustrated) of the notch -35-, allowing the rotation of one piece with respect to the other.

    Figure 12 shows how the assembly of the upper parts -52-, -62- of the third part -5- and the fourth piece -6- is carried out on the lower parts -52'-, -62'- of these, the first piece -3- and the second piece -4- already being joined. It is observed how the upper part -62- of the fourth piece -6- is positioned so that the stop -57- arranged in the groove of the upper part -52- of the third piece -5- is arranged inside the notch -65- shaped circular trapezoid. Again, the stop -57- can move through the notch 15 -65-, offering the possibility that the piece -5- rotates with respect to the piece -6-. The rotation is limited by the path of the notch -65-, since the stop -57- contacts the limits -66- (see references -56- and -56'- in figure 7) of the notch -65-.

    The connection interface between parts is arranged in a plane perpendicular to the plane of the outlet, that is, perpendicular to the plane in which the housings for the plugs are located. In this way, the outlet of each piece can adopt different orientations.

    Once the pieces are joined, the notch -65- of greater radius defines a path for the stop 25 -57-, which can move along it between the limits -66- (only one illustrated) of the notch -65- . In the embodiment of the present invention shown in the figures, the path of the notch -65- of greater radius allows a 90 ° rotation of one piece with respect to the other. For this purpose, the notch -65- has a length of 90 ° of arc of circle with the addition of the width of the stop -57- in one of the ends of the notch -65-. 30
