In relation to Figures 1 to 6, it is described a portable socket with multiple sockets according to the invention, indicated as a set by the numerical reference one.

The socket of sockets 1 is formed by a box-shaped housing 2 with an elongated shape substantially parallelepiped, in which a plurality of electrical functions 3, especially sockets of Electrical power suitable for receiving electrical outlets. By way of example, the socket of sockets 1 provides nine electrical functions 3. To be more precise, six functions electric are arranged three by three on the two walls opposite sides of housing 2 and three electrical functions they are arranged on the upper wall opposite the base wall 4 (Figures 3 and 4). No electrical function is provided in the base wall 4 since the purpose of this wall is to support Against a stand. In detail, the electrical functions 3 which are provided on the upper wall of the housing 2, are configured as circular seats 5 that provide paths Guide 6 for the introduction of plugs and tabs resistant metal 7 forming ground contacts resistant.

On the upper wall of the housing 2, provides a seat 8 suitable to accommodate, for example, control devices and their corresponding switch, or protection devices, or indicating devices light (for example LED), or protection devices by fuses

As shown in Figure 2, in the rear wall 9 of the housing 2 a hole 10 is provided to access the inside of the housing from which a electric cable 11, connected, for example, to a straight plug 12 for connection to an outlet on the power grid.

On the upper surface of the housing 2, on the  front, in a central position, there is a first hole thru 13 that extends to the base surface (Figures 3 and 4). As shown in Figures 3 and 4, the first hole through 13, in the part that goes to the base surface 4, has a slot 18 that allows the multiple socket to be hung on hooks sockets 1. Around the first through hole 13, in the upper surface of the housing 2, there is a cavity 14 for receive, for example, the head of the screwing means.

The upper surface of the housing 2 has in its posterior part a slightly chamfered part 15. In the chamfered part 15, on the side so that it does not interfere with the power cable 11, a second has formed through hole 16 that reaches the base surface 4. It has a cavity 17 formed around the second through hole 16, in chamfered part 15, to receive, for example, means of screwed

Thus, the multiple portable socket sockets 1 can be fixed to a flat surface by two screws, which extend through the respective through holes 13 and 16.

As shown in Figures 3 and 4, it is have formed on the base surface 4 of the housing 2 two special seats 20 arranged transversely to a distance of about one third of the housing length 2 from the front end and the rear end, respectively, of the housing 2. Each special seat 20 has a shape substantially rectangular. In special seat 20 you they provide two bridges 21 that are part of the surface of base 4. Bridges 21 divide seat 20 into three openings: one elongated central opening 22 and two smaller side openings  23 that communicate with the central opening 22. The openings sides 23 are advantageously open towards the outside to allow the transversal introduction of fixing means adequate. More precisely, the central opening 22 opens in the base 4 of the socket outlet, while the side openings 23, in addition to having opened at base 4 of The power socket housing, have also been opened in the edges that have formed between the base 4 and the side walls of the power socket housing.

As shown in Figure 4, the seats 20 are suitable for receiving a straps 30 of type standard. Said belts 30 possess, in a manner known to yes, a free end 31 and a retaining block 32 fixed in the other end and capable of receiving the free end 31. Straps 30 They are jagged. The free end 31 can be introduced into the block holding 32, so that a loop is formed, and can be pushed so that the loop is tightened and loosened in the opposite direction to  The extension of the loop.

By using the straps 30 the socket of sockets 1 can also be attached to irregular or rounded surfaces such as posts, tubes or sections, such as table legs or shelf uprights, by example. To be more precise, the free end of the strap 30 is introduces into a lateral opening 23, impersonates the opening central 22 and is exited through the other side opening 23, being retained by the two bridges 21. Thus the belt 32 it is wrapped around the section in which the socket of sockets 1, maintaining the base surface 4 leaning against the section. Finally the free end is introduced 31 of the belt in the retaining block 32 of the belt.

In this embodiment with the straps 30, the side edges of side openings 23, instead of open, possibly can be closed by means of walls thin that facilitate the introduction of the belt 30.

In addition, belts 30 can be introduced also in the through holes 13 and 16 to fix the socket of 1 outlets on the front and back, respectively.

In relation to Figures 5 and 5A, they are shown two bars 110 that can be introduced in the seats 20 to fix the socket of sockets 1 on the surfaces flat.

The bar 110 has a fastener 111 in one of its end that is suitable for snagging with a closure on the inside the side opening 23. The other end of the bar 110 It is larger than the body of the bar and has a hole in the form of a slot 112 suitable for receiving the fixing means such as screws 113. In this way the end of the bar 110 with the latch 111 is inserted into a side opening 23, pretends to be through the central opening 22 and fits in to lock into the other side opening 23. In this situation the end with hole 112 protrudes out of the housing of the socket of sockets 1 and the base of the end of the bar 110 with the hole is positioned in the same plan at same as the base 4 of the socket of sockets.

Figure 5A shows the socket of sockets  stream 1 with the bars 110 placed in their respective seats 23 and ready to be fixed to a flat surface. This solution allows the socket of multiple sockets 1 to be hold on flat surfaces, without having to use the perforated extensions or fixing holes (for example holes 13 and 16 with the respective cavities 14 and 17) that are in the parallelepiped housing of the socket of sockets. From In this way, the socket housing is aesthetically improved of multiple sockets, since avoiding having to make holes and extensions since they are not used in case of using the socket of multiple sockets only in portable state

The two clips 40 are shown in Figure 3 adapted to fit seats 20 of base 4 of the socket of sockets, to fix the socket of sockets current to a surface. As shown in Figure 3A, the clamp 40 has the shape substantially as that of a triangular frame. Two type holes have been formed slotted 44 in the hypotenuse 43 of the triangular frame 40, for receive the screwing means that allow the clip 40 to be held to a surface, such as a table.

The major leg 41 of the triangular frame 40 is inclined in relation to hypotenuse 43 in approximately 30 °. In the larger leg 41 there are two protruding hooks 42 that are arranged in asymmetrical positions and are designed to engage, in a very tight relationship, in one of the two side openings 23 and in the central opening 22 of the seat 20, respectively. In this way, the clip 40 is held completely to the socket of sockets 1.

In minor leg 45, two have been performed slots 46 to receive the screwed means for clamping to a flat surface.

Figure 3B illustrates the clamping of the socket of sockets 1 on top of a table 100. The hooks  42 of the clip 40 are inserted into the respective openings 22 and 23 of the base 4 of the socket of sockets 1 so that can hold on Screws 47 are inserted into the holes of slotted type 44 of the major leg 43 of the clip 40 that is attached to the surface of table 100. In this way, the socket of sockets current 1 is fixed on top of table 100 and its lower surface 4 is inclined at approximately 30 ° in relation to the table surface 100.

Figure 3C illustrates the clamping of the socket of sockets 1 under a table 100. The hooks  of the clips 40 are fixed to the socket of sockets 1. The screws 47 are inserted into the grooved type holes 46 which are arranged in the smaller leg 45 of the clip 40 that is held to the surface of table 100. In this way, the socket of sockets of current 1 is set below table 100 and its surface of base 4 is inclined at approximately 90 ° in relation to the table surface 100. Naturally, it is possible to set the socket of sockets with its base surface at 90 ° above from surface 100 or 30 ° below surface 100, as well as it is also possible to fix the socket of sockets in inclined surfaces, according to needs.

In this embodiment with the staples 40, the side edges of side openings 23, instead of being open, can be closed; what is really important is the fact that the hooks 42 of the clips 40 can be inserted in the lateral openings 23.
