Description

I "LUGGAGE BOX FOR ELECTRICAL AND ASSEMBLY"

Field of the invention

The present invention relates to housing boxes 5 for electrical appliances such as power sockets and switches.

The invention further relates to an assembly comprising a housing box and an electrical apparatus to be carried by said housing box.

Background of the invention

It is well known that in wall-mounted electrical installations a housing box is arranged in the thickness of a wall receiving the portion of the electrical apparatus intended to be arranged in the wall thickness, and that the apparatus comprises a support façade over the wall. wall around a hole through which the housing box flows. Fixing the electrical appliance over the housing is usually done by means of fixing screws supplied with the appliance.

Generally, these are conventional screws whose heads rest on an appliance bracket and whose threaded bodies are screwed into the screw holes provided in the housing.

The bracket of the apparatus may also be secured to the housing 25 by means of lateral securing clips driven by the securing bolts, said clip screws coupled through the apparatus bracket. When the clip “screws” are tightened in the bracket, the securing clips deflect and anchor in the box receiving cavities, thereby retaining the bracket in the box.

It is not always easy to fit the box to the wall to an ideal depth to screw the bracket into the box. When an installer fits the box very deeply into the wall, the conventional screws are then very short and the installer generally replaces them with other longer screws.

Various solutions have already been proposed to enable the screws supplied with the apparatus to be used over a wide range of housing depths. KR 2009-0094909 is known for a housing housing in which the organs of different lengths 5 are supported by screwing into a cavity in the housing. These organs form extensions and present alternative cavities for the fixing screws. The extent is chosen according to the housing depth of the box in the wall.

Furthermore, BR 9006619 and BR 0005342 of housing housings are known where metal anchors having various bolts of different lengths are attached to the housings. Depending on the depth of the housing housing, the anchor member is rotated about it until the adapted length bolt tongue is placed in front of the electrical apparatus.

The document EP 2 209 17 6 of a housing housing having an anchor member having a single cavity is further known, and the anchor member is inserted more or less deeply into the housing as a function of the housing depth thereof in the wall. .

The invention aims to provide a similar housing box that is particularly simple, convenient and economical.

Detailed Description of the Invention

Figures 1 to 3 illustrate a housing 1 in different configurations detailed below.

The housing 1 comprises a molded body 2 of plastics material.

This body 2 has four side walls respectively a first side wall 3, a second side wall 4 opposite the first side wall 3, a third side wall 5 and a fourth side wall 6 opposite the third side wall. side 5.

The body 2 also has a bottom wall 7 which joins the four side walls 3 to 6.

The body 2 furthermore has a frame 8 also joining the four side walls 3 to 6, that frame 8 being opposite the bottom wall 7. This frame 8 forms an edge over the upper body 2 of the housing 1.

The body 2 also has two recesses 9 symmetrically arranged. The recesses 9 are respectively formed at the same time as the third side wall 5 and the back wall 7, and that the fourth side wall 6 and the back wall 7.

These recesses 9 form the reinforcements of the housing 2 body 2.

The housing 1 has two symmetrically arranged chimneys 10 ("chimneys"). _

The internal space in each chimney 10 flows, respectively, into one of the recesses 9 and flows over the upper body 2 of box 1.

These chimneys 10 are formed by a portion 14, respectively, of the third side wall 5 and the fourth side wall 6, this portion 14 being thicker than the rest of the respective side wall.

5, 6.

Each chimney 10 is furthermore formed by two sidewalls 11 and 12 which each connect to a respective sidewall 5,6 and extending from the inner surface of the respective sidewall 5,6 and a wall. 13 which joins the sidewalls 11 and 12.

The sidewalls 11, 12 and 13 have a defined height between the bottom wall 7 and a horizontal plane passing through the edge 8, while the thicker portion 14 has a defined height between the respective recess 9 and that same plane passing through the edge. edge 8.

Each chimney 10 comprises a bolt tongue

16 formed together of the same plastic material with its side wall 13.

Each bolt 16 has a height substantially equal to the height of the thicker portion 14.

Each bolt tongue 16 furthermore has at its upper end, i.e., substantially in the same horizontal plane as the edge 8, a cavity 17 adapted to receive a set screw, as will be detailed below.

The housing 1 further comprises two portions 18 which are movable and are arranged symmetrically with respect to one another.

Each parcel 18 is arranged at least partially in the internal space in a respective chimney 10.

Each portion 18 has a cavity 19 adapted for receiving a set screw as well, as detailed below.

Each portion 18 may move in the internal space in the respective chimney 10, particularly due to an internal space 20 which each portion 18 defines.

The positions of the plots 18 which are illustrated in figures 1 to 3 will now be described very briefly.

Figure 1 illustrates the injection position of the housing 1 which is embodied, as will be seen in more detail below, from a single block of plastic material including each portion 18.

Figure 2 illustrates the same housing box 1, with each portion 18 being spare here with respect to the chimney 10, otherwise stated in a raised configuration 5.

Figure 3 also illustrates the same housing box 1 with each portion 18, which are in a low position, otherwise stated in a configuration completely folded into the internal space in the respective chimney 10. 10 It will now be described in more detail. , one of the plots 18 with reference to figure 4, assuming that the two plots are identical.

Here, the parcel 18 is illustrated in injection position as in figure 1.

The portion 18 comprises a base 21 and two stops 22 between which the internal space 20 is defined, particularly allowing the articulation of the portion 18 in the internal space of the chimney 10, despite the presence of the bolt tongue 16.

The portion 18 has an upper surface 23, two side surfaces 24, a front surface 25 extending perpendicular to the upper surface 23, a bottom surface 26 extending obliquely to the upper surface 23, as well as a lower surface 25 joining together. the front 25 and bottom 26 surfaces.

The bottom surface 26 has two straight portions — sloping -different and -a curved portion situated between the two straight portions.

The parcel 18 is of plastic material and formed together with the chimney 10 to which it is attached.

The housing 2 body 2 comprises a thin portion 28, visible here on the side of the housing arrangement 1 material arrangement, but more visible below, which forms a hinge for pivoting portion 18 into the internal space in the chimney. 10 for passing this portion 18, particularly from its injection position to either of its raised and folded positions. Therefore, the thin portion 28 of plastic material forms the junction between the plastic material portion 18 and the wall 13 of the chimney 10, which is also of plastic material.

5 The parcel 18 furthermore has a spur 29 rooted at each of the stops 22 at the level of the front surface 25. These spurs 29 are oriented towards the base 21 of the parcel 18, ie towards the upper surface 23 , and towards the outside.

The portion 18 furthermore has a pointed portion 30 on each of the stops 22 at the intersection between bottom surface 26 and lower surface 27, ie opposite spurs 29. Each pointed portion 30 is rounded at its apex end.

In the vicinity of these pointed portions 30, portion 18 has two side protuberances 31 protruding from each respective side surface 24.

These protrusions 31 are in the form of parallelepiped blocks having one side from which only a portion is attached to respective side surface 24 of portion 18.

As is particularly apparent from Figures 5 and 6, the front surface 25 has a stretched shape which is narrower on the base side 21 than on the spur side 29.

Figure 4 further shows the truncated cone-shaped guide slots 32 arranged on the outer surface of the sidewall 13 and the ribs 33 arranged in the section 14.

The truncated cone-shaped guide slots 32 extend from the bottom wall 7 almost to the upper end of the side wall 13 and have a greater clearance at the bottom wall level 7 than at the side wall end level 13.

As for reinforcements 33, they have the shape of armholes at edge level 8.

The truncated cone-shaped guide slots 32 are most noticeable in figures 5 and 6.

In these figures 5 and 6, it is also seen that the outer surfaces of the sidewalls 11 and 12 of the chimney 10 each have a truncated cone-shaped portion 15 debutting at about the same level as the base of the portion 14 and extending into each other. extending towards the height to the top edge of the respective walls

11 and 12.

At the lower end of each truncated cone portion 15 is a stop bracket 34 protruding from its side wall 11, 12.

As is apparent from figure 5, portion 18 is connected to chimney 10 only at side wall level 13 by the thin portions 28 (not visible in this figure) described above.

Opposite the chimney, that is, on the side of portion 14, there is a gap between this portion 14 and portion 18.

Figures 4, 5 and 6 further show how the housing 1 is injection molded from plastics material and, in particular, the chimney 10 with its bolt tongue 16 and the portion 18 it receives in its internal space.

The molding portions of a mold (not shown) are at the same time at the level of the recesses 9 and the 25 truncated cone-shaped guide slots 32 to the bottom of each slot 32 formed by the wall 13 and situated against the portions on each other. truncated cone shape 15 from sidewalls 11 ~ and 12 to plow supports 34.

Other details useful for understanding the housing box molding 1 are visible particularly in Figures 9, 14 and 19.

It will now be described in detail, with reference to figures 7 to 11, the positioning that admits one of the plots 18 in injection position.

Figure 7 is a top view of housing 1 showing portion 18 to the right of housing 1 in injection position. Figures 8 to 10 illustrate the positions of the housing box portions 18 in the internal space of the chimney 10 following the section planes shown in figure 7, and figure 11 shows in detail the thin portion 28 forming a hinge between the wall lateral 13 and the parcel 18.

In this injection position, the portion 18 is at the same time partially retracted into the internal space in the chimney 10 and partly outside the internal space of the chimney 10. It can be seen from figures 8, 9 and 10 that the passages are 10 formed by the molding portions of the mold, in order to injection mold into a single piece of plastics material, the portion 18 with the chimney 10, and more generally the housing 1 as described above.

In addition, figures 7 to 10 show a joint plane between the mold shaping portions at the intersection of upper surface 23 and bottom surface 26.

As will be seen below, parcel 18 is here in an intermediate position between its high position, called the high setting, and its low position, called the folded setting.

In this injection position, the front surface 25 and the upper surface 23 of the portion 18 are directed 25 forward of the housing, while the bottom surface 27 is directed to the bottom in the internal space of the chimney 10, and the surface Bottom 26 is oriented vertically at the same time in the internal space in the chimney 10 and outside the internal space of the chimney.

In this injection position, the portion 18 is in any case free to be moved, at least to some extent, in the front or bottom direction.

This injection position allows the housing to be

1 is not in a working position as such, but rather in a position in which the box is to be delivered to the customer after its manufacture, so parcel 18 is likely to be slightly higher or, on the contrary, more folded. .

As shown in Figure 11, the sidewall 13 has a truncated cone-shaped portion 35 extending toward its upper end.

This truncated cone-shaped portion 35 facilitates the insertion and removal of molding portions of the mold for injection molding the housing 1.

The thin portion 28 has a thickness sufficiently small for the hinge function to be possible, but also a thickness sufficiently large for this thin portion 28 to be robust.

Referring now to detail, with reference to Figures 12 to 16, the positioning of the portion 18 in the housing 1 when it is in its elevated configuration.

In the elevated configuration, portion 18 is in a high position and almost entirely unfolded from the internal space in chimney 10.

In this position, the spurs 29 of the parcel 18 are in contact with the upper end of a respective truncated cone-shaped guide groove 32, but each of these spurs 29 is locked in the forward direction by the upper end of the sidewall 13.

In addition, the pointed portions 30 of the parcel 18 rest in the respective pit 33 arranged in the portion 14 at edge level 8.

These pointed portions 30 are then,

- partly out of the internal space not chimney 10.

The portion 18 has its upper surface 23, its front surface 25 and its bottom surface 26 which are outside the internal space of the chimney 10, and the lower surface 27 which is in the internal space in the chimney 10 in a substantially horizontal plane.

The protrusions 31 of the parcel 18 are arranged substantially horizontally and topped against the edge 8 to prevent the parcel 18 from moving beyond its elevated configuration in which it is in the high position.

The spurs 29 also prevent the portion 18 from going beyond this high position.

In this position, the portion 18 covers the bolt 16 and, consequently, the cavity 17, so that the cavity 19 of the portion 19 is in the foreground to receive a set screw, as described below.

The passage from the injection position to the elevated position 10 of the portion 18 is operated thanks to the thin hinge portion 28 which allows the portion 18 to be moved in the high direction here and thanks to the pointed portions 30 which form an easily surmountable dam for a user placing the 18th installment in the high configuration.

The thin portion 28 is adjusted until the portion 18 is in contact with the truncated cone portion 35 of the sidewall 13.

In addition, it had to overcome the dam made by the pointed portions 30 against the inner surface of portion 14.

At this elevated position, portion 18 then forms an improvement.

Figure 22 shows a use of the housing box described above.

Figure 22 illustrates a wall 40, such as a wall, and an assembly 50 provided with an electrical appliance 41 and housing 1.

Electrical apparatus 41 comprises a mechanism 42, here a switch, and a formed facade 43 formed of an apparatus support 41 and a cap for covering the mechanism 42 and the support.

The wall 40 receives in its thickness the housing 1 and this box 1 houses a part of the apparatus 42 which is equally at the thickness of the wall 40.

The bracket 41 comprises the through bolt housings 44. Here, the housing 1 is fitted very deeply into the wall 40 and the bolts 44, which are generally of standard size and perfectly adapted to the fixing of the housing. appliance bracket 41 with housing housing 1 are not long enough to be received in the cavity 17 of the bolt tongue 16.

Thanks to the portions 18 which are each in their high position, the securing screws 44 are received in the respective cavity 19 of the portions 18 and the apparatus holder 41 is thus fixed to the housing 1 without particular difficulty.

This apparatus support is further supported on the wall 40 around the hole through which the housing box flows into the housing and the cap is equally supported on the support and on the wall 40 to form the facade.

Thus it is possible, despite the very deep fitting of the housing to the wall thickness 40, to simply fix the electrical apparatus 41 to the housing 1 to form an assembly 50 which is reliable and robust over time.

It will now be described in detail, with reference to figures 17 to 21, the positioning of the portion 18 when it is in its folded configuration, otherwise stated in a low position.

In this folded position, the parcel 18 is completely inserted into the internal space of the chimney 10.

The front surface 25 is oriented upwards in the internal space of the chimney 10, the upper surface 23 is vertical and opposite to the inner surface of portion 14, the lower surface 27 is also substantially vertical and opposite to the outer surface of sidewall 13 and bottom surface 26 is directed downwardly into internal space in chimney 10.

The spurs 29 and the pointed portions 30 are in turn free, the former being oriented upwards into the internal space of the chimney 10 and the latter downwards into the internal space of the chimney 10.

In this folded position, the side protuberances 31 are confined between the outer surface of the sidewall 13 and the stop brackets 34.

The thin hinge forming portion 28 holds portion 18 downward. The portion 28 carries the weight of the portion 18. In this folded position, the portion 18 leaves free access to the bolt tongue 16 and, consequently, to its cavity 17.

The hinge-forming fine potion 28 allows the injected position of portion 18 to pass to its folded position, but it is also possible to move from the elevated position of portion 18 to the folded position of portion 18, 15 counteracting the blocking force exerted by the pointed portions 30 resting on respective armholes 33.

Accordingly, it is particularly easy to pass from one of the positions of portion 18 by its displacement within the internal space of the respective chimney 10, in particular thanks to the thin hinge forming portion 28. If well understood, the realized description of figures 7 to 20 is valid for the other non-visible portion 18, also in detail, but present particularly to the left in figures 1 to 3.

Figure 23, as Figure 22 described above, shows the use of such a housing 1.

In Fig. 23, the housing "housing" -1 is prominently fitted to the wall 40, that is, the edge 8 of the body 2 is substantially in the same plane as the surface of the wall 40.

The set 50 thus represented has a congestion, and in particular a depth, less than that of the set 50 of figure 22.

The plots 18 are folded into the internal space of the respective chimney 10 with the defined space 20, the respective bolt tongue 16 is free to be accessed.

The bolts 16, and consequently the cavities 17, are sufficiently close to the bracket 41 so that the securing bolts 445 are directly received in the cavities 17 of the respective bolts 16.

It will now be described, with reference to Figures 24 and 25, a second embodiment of a housing box 100 according to the invention.

Unlike the housing box illustrated in figures 1 to 23, housing box 100 is provided with a chimney 161 which has no bolting tongues. Housing box 100 comprises an anchor portion 160 different from anchor portion 18 of housing housing 1.

The anchor portion 160 is internally attached to the chimney 161 in the same manner as the portion 18 to the chimney 10, i.e. by a thin portion of hinge-forming plastic material (not visible).

Since chimney 161 has no bolt bolt, all the internal space in this chimney. 161 is dedicated to the pivoting movement of portion 160. This portion 160 has a curved surface 165 over which nearly a central groove 163 forms an area for receiving a bolt securing an electrical apparatus .

This non-emergent central slot 163 has a plurality of pre-cavities 164 successively disposed in the slot 163 to form a plurality of sub-areas for receiving the electrical appliance securing screw.

Each pre-cavity 164 is adjacent to at least one other pre-cavity, with between them a portion of plastic material delimiting its respective perimeter. The portion 160 furthermore has a straight face 166 provided with a plurality of teeth at its edges to form a rack 162 which cooperates with the ribs (not shown) arranged on the chimney 161 against this rack 162.

In this way, it is possible, thanks to the hinge and rack 162, to position the portion 160 following a plurality of connected positions, each having a pre-cavity 164 for receiving the fixing screw of the electrical apparatus.

Depending on the depth of engagement of the housing 100 in the thickness of the wall, it is simple and convenient to raise or lower the portion 160 in the internal space of the chimney 161 to arrange a pre-cavity 164 in front of a facade fixing screw of an electrical appliance.

Rack teeth 162 also form a dam to prevent free movement of portion 160 from one position to another.

The mounting bracket mounting screws are self-tapping to form the required cavity in the selected pre-cavity 164.

In variants not shown:

the cavities of the bolt tongue and / or the portion are in fact the pre-cavities formed by the non-spare holes and the fixing screws of the electrical apparatus are self-tapping;

- the chimney, the bolts and the parcel have different dimensions from those shown in the figures from 1 to 23. For example, the parcel has a higher height, thus accepting an even deeper engagement of the housing in the wall thickness;

- the anchor portion is of a different shape closer to that of a claw, shim, ear or lining; and / or

- Electrical appliance is not a switch, but some other appliance like a power outlet.

It is more generally considered that the invention is not limited to the examples described and represented.
