Description

Device pad with a box half-recessed through the duct and how to use it

Technical field

The invention generally relates to the attachment of any device, for example any electrical device, such as an electrical outlet and others, to any substrate, for example a wall.

BACKGROUND OF THE INVENTION

In certain devices, for this attachment, a cable, usually called an electrical cable, is laid on its base to support and protect the electrical conductors necessary to connect the device, and on the other hand a housing or support frame mounted directly on the corresponding substrate. which is connected to the line and even exceeds it locally in the transverse direction.

The advantage of such an arrangement is that it allows quick installation and facilitates later interventions.

Its disadvantage, however, is that it leads to a considerable grip of the substrate.

In other devices, the guide forms a groove of sufficient height to accommodate not only the electrical conductors, but also the fixture, whether it is directly attached to such a groove or whether it is fastened to it by means of a box located inside the groove. that is properly planted in it.

This arrangement, which has the advantage of reducing the engagement of the substrate, is disadvantageous in that the groove assembly projects relatively strongly above the substrate.

In other devices, the device is fastened by means of a box embedded in the substrate, either by pre-casting the box into the substrate, or in such a manner that the substrate is then appropriately excavated as necessary.

This arrangement, which minimizes both the engagement and the protrusion of the substrate, necessarily requires that the electrical wiring used, i.e. a single tube, be pre-installed in the substrate. This arrangement does not facilitate later interventions.

It could therefore not be suitable for all installations, especially those to be carried out in existing premises.

SUMMARY OF THE INVENTION

According to a first aspect, the invention generally relates to a device, in which case, on the contrary, satisfactory, which does not have the above-mentioned disadvantages.

More precisely, the subject of the invention is, in particular, a support of a device of the type comprising, in combination, a conduit intended to be laid on its base on any substrate, and a box suitable for mounting in the conduit. in that the box, the greatest height of which is greater than the height of the conduit, is intended to penetrate its bottom through an aperture provided for this purpose locally on that day, and to at least partially slide into the recess in the adjacent substrate; it further relates to a method which, in order to use the machine support, comprises cutting a hole with the contour of the whipper at the bottom of the guide, recessing the recess in the adjacent substrate directly below the hole and sliding the box into the recess through the opening.

According to the invention, the box thus extends partly into the guide and partly into the adjacent substrate.

In other words, it is embedded in the substrate.

Thus, the engagement of the substrate by the box preferably takes place within the engagement of the substrate by the conduit and does not result in its enlargement.

Accordingly, and in contrast to the groove, the guide can advantageously have only a small height, as is usually the case with guides serving only to accommodate and protect electrical conductors.

The projecting of the whole above the substrate is therefore preferably limited.

Advantageously and in accordance with a second aspect of the invention, a protruding tubular partition for seating the box is provided longitudinally at the bottom of the conduit, and the box is provided with at least one and in practice two pins whose cross section is at least partially complementary to that of the tubular partition.

Thus, a simple and safe maintenance of the box without screwing or snap mechanism is advantageously ensured.

DETAILED DESCRIPTION OF THE INVENTION

As shown in the drawings, and in particular in FIG. 1 and 2, it is the attachment of any device 10 to any substrate 11.

In the embodiment shown, the device 10 is an electrical device.

Specifically, an electrical outlet is mentioned as an example.

Since such a device 10 is known per se and does not form the subject matter of the invention itself, it is not described in detail here.

Suffice it to mention that it comprises a mechanism 12, that mechanism 12 is releasably connected to a fixing plate 13, usually called a washer, that the fixing plate 13 has, in opposite positions, two bores 14 suitable for passing the screws 15 necessary for the desired fixing, and it can be covered by a decorative cover 16, which can be inserted into the mechanism 12 by a screw 17.

In the illustrated application, the substrate 11 is a wall, and more precisely a lower part of the wall, i. the one immediately adjacent to the corresponding floor 18.

As shown, the wall forming the substrate 11 may be solid.

However, it may also be a plate attached to such a massive wall, as is the case with the reconstruction of certain spaces.

In order to secure the device 10 to the substrate 11, a substrate 20 of the device is used in a known manner.

This device support 20 also comprises in a known manner, in combination, a guide 21 for receiving its bottom 22 in a substrate 11, and a box 23 suitable for fitting into a guide 21, which is intended to receive the fixture 10 in further described ways.

According to the invention, the box 23, the maximum height H1 of which is greater than the height H2 of the conduit 21, is intended to penetrate the bottom 22 of the conduit 21 through an aperture 24 provided for this purpose locally on this bottom 22 and to be inserted at least partially into the recess 25 in the adjacent background 11.

The guide 21 typically comprises a body 26 having a bottom 22 and a cover 27 that is adapted to be fastened, for example by a latch mechanism, to the body 26.

In practice, the body 26 and the cover 27 are extruded profiles made, for example, of synthetic material.

However, since the guide 21 does not fall within the scope of the invention in all its details, only the elements necessary for its understanding will be described below.

In this regard, it is sufficient to note that, in order to fit the box 23 and according to the arrangement, described in more detail below, from the guide at its bottom 22, i. at the bottom of its body 26, a tubular partition 28 extends longitudinally.

The tubular partition 28 is defined on the one hand by two walls 29, substantially parallel to one another, extending substantially perpendicular to the bottom 22, each formed by its projection, and on the other hand by two walls 30/ also substantially parallel to each other, extending substantially parallel to each other. and keep the two walls 29 at a distance from one another along their free edge and the other at a certain distance from the free edge.

In the embodiment shown, both walls 30 have a transverse profile of a wedge whose edge faces the bottom 22.

It follows that the cross-section of the internal volume 31 of the tubular partition 28 defined simultaneously by the walls 29 and 30 is roughly similar to the rafters.

Apart from the tubular partition 28, the bottom of the conduit 21 does not necessarily have to be flat, as shown in FIG. 5A, 5B, 6 and 7.

Conversely, as shown by way of example in FIG. 1, it may have at least in its width one or more half-wave deformations 32 which extend over its entire length, in particular to reinforce or bend the fixture with feet in the cavities thus formed, and / or may have one or more protruding ribs 33, which also extend over its entire length and allow, in particular, to locally locate any accessory (not shown), such as a removable partition.

In addition to the bottom 22, the guide body 26 also has one or more wings 34 longitudinally, which also extend over its entire length.

The maximum height of H2 line 21 is the height of the highest wing 34 ·

Thus, the tubular partition 28 has a height at most equal to this highest height H2.

In the embodiments shown in more detail in FIG. 1 to 9, the box 23 has only one station P for accommodating only one device 10 and has a circular outline in plan view.

It thus has a total of one bottom 36 and one side wall 37.

For example, this side wall 37 is generally cylindrical.

However, as a variant, it may have more or less a tapered cone shape.

According to the invention, the box 23 is provided with at least one pin 38 whose cross-section is at least partially complementary to the inner volume 31 of the tubular partition 28 of the conduit 21 and which is intended to be received therein.

In practice, the box 23 is provided with two pins 38 located in opposing positions.

In the embodiments shown in FIG. 1 to 7, each of these pins 38 is supported by an elastically deformable shoe 39 that belongs to the box 23 and which virtually forms a single unit with it.

In the embodiment shown in more detail in FIG. 1 to 5, the core R of this elastically deformable shoe 39 is e.g. the portion forming the pivot axis about which it can elastically deform, shown in FIG. 5A by dashed lines, substantially perpendicular to the bottom 36 of the box 23.

More precisely, in this embodiment, the upper portion of the side wall 37 of the box 23, i. a portion of this side wall 37 furthest from its bottom 23, at least locally divided into a plurality of posts 40, each elastically deformable shoe 39 carrying a pin 38 extending from one of these posts 40.

Since, in practice, two pins 38, and thus two elastically deformable shoes 39, are provided, both elastic shoes 39 extend from one post 40 and are disposed on both sides thereof.

In practice, each of the elastically deformable shoes 39 occupies one quarter of the circle, counted from the post 40 from which it exits.

It follows that the upper portion of the side wall 37 of the box 23 is continuously circular only over a portion of its periphery, or in other words, the upper portion has two distinct circular portions, i.e., a continuous circular portion 40 ¹ to which elastically deformable shoes 39 and. the pillar 40 from which they are based and the part 40 divided into pillars 40.

In the embodiment shown, each of the two parts occupies 40 ^l . 40 of the top of the side wall 37 of the box half the circumference.

The posts 40 extend longitudinally in an extension forming a line of the bottom of the side wall 37 of the box 23.

They have a height H1 which is the same for all and which is substantially equal to the height of the elastically deformable shoes 39, which extend to the same height as the upper part thereof.

This height H1 may, as shown, be lower than or equal to or higher than the height H'1 of the bottom of the side wall 37.

The greatest height H1 of the side wall 37, however it is, is defined by the sum of the previous heights H1 and H'1.

The bottom of the side wall 37 of the box 23, i. the portion of this side wall closest to the bottom 36 is consistently circular.

In the illustrated embodiment, the elastically deformable beads 39 are reinforced on their outer surface by a square mesh of axial ribs 42 and transverse ribs 43.

The posts 40 are also reinforced on their outer surface by one or two axial ribs 44.

Only one post 40 is contiguous with the continuously circular portion 40 'of the upper side wall 37.

For the second segmented portion 40, in the embodiment shown, several columns 40 spaced apart from each other, for example three, are provided.

In the embodiment shown, the pins 38, supported by the elastically deformable shoes 39, are integral ^with these shoes.

The box 23 is therefore preferably a monoblock in this case.

To relieve it, the pins 38 are hollow.

In the embodiment shown, these pins 38 are generally parallelepiped.

They have two walls 46 which are substantially parallel to one another and which extend substantially perpendicular to the bottom 36 of the box 23. and two walls 47, also substantially parallel to one another, which are substantially parallel to the bottom 36 of the box 23 and span the previous walls 46 along their free edge.

In practice, only one of the walls 47 has a wedge-shaped profile, complementary to the wall profile 30 of the tubular partition 28 of the conduit 21.

It is a wall 47 which corresponds to the wall 30 which is concave on the outside.

Thus, the corresponding wall 47 is also concave from the outside.

To facilitate their insertion into the tubular partition 28 of the guide 21, the free end of the pins 38 on the side of these pins 38 opposite the elastically deformable shoes 39 is bevelled by the edge 49.

In practice, the pins 38 are located at the ends of the elastically deformable shoes 39.

Thus, each of them extends in opposite directions to each other at the ends of the continuously circular portion 40 * of the upper side wall 37 of the box 23 and so that it projects above the outer surface of the elastically deformed beads 39.

In the embodiment shown, the elastically deformable beads 39 have on their inner surface directly at the location of the pins 38, but the oppositely directed projections 50, which extend axially, i.e., in the opposite direction. parallel to the box axis 23. and each of which is elongated by a protrusion 51 on the inner surface of the lower portion of its side wall 37, and which have for receiving the screws 15 at their upper end of the bore 52.

In the embodiment shown, the box 23 has a shoulder 54 transversely at half height on the outer surface of the side wall 37 for abutment against the bottom 22 of the guide 21.

In practice, the collar 54 is located at the mouth of the continuously circular lower portion of the side wall 37 and the pillar 40 belonging to the upper portion thereof, directly extending therefrom by its axial ribs 44.

Preferably, and as shown, the collar 54 also has two depressions 55 locally in opposing positions, directly at the location of the pins 38, for insertion into the tubular partition 28 of the conduit 21 and rotatably immobilizing it.

The application of the pad 20 of the device according to the invention can be carried out, for example, as follows.

Firstly, for example by means of a saw, a cut-out of the opening 24 with the outline of the box 23 in the bottom 22 of the guide 21 is ensured, i. in the day of his body 26.

Of course, this opening 24 extends not only to the bottom 22 but also through the passageway to a tubular partition 28, which is thus locally interrupted.

Then, for example by means of the same saw, the recess 25 in the substrate 11 is secured directly at the opening 24 in the guide 21.

Finally, it is ensured that the box 23 is inserted into this recess 25 through the opening 24 in the guide 21.

After this insertion, it is ensured that each of the pins 38 of the box 23 is inserted into the pre-cut-outs of the partition 28 of the guide 21.

In this case, for example, the elastically deformable feet 39 are clamped, i.e., they are closed. they are approached according to the arrows F1 in FIG. 5A, and then, in connection with returning to the original configuration of these elastically deformable shoes 39, the pins 38 are inserted into the slots in the tubular partition 28 according to arrows F2 in FIG. 5B.

After the box 23 is properly seated in the duct 21, the cover 27 is attached, after the opening 24 'of the same contour as the hole 24 of the bottom 22 has also been formed, on the duct body 26.

By means of screws 15, the mechanism 12 of the device 10 is fixed to the box 23 by a fixing plate 13.

The ornamental cover 16 is then attached to the mechanism 12 by a screw 17.

Thus, the cover 27 of the guide 21 is locally engaged between the box 23 and the mounting plate 13 and the decorative cover 16 of the device 10.

Thus, as can be seen, the supply of electrical conductors to the box 23 extends between the columns 40 of the articulated portion 40 'of the upper portion of its side wall 37, while a continuously circular portion

40 ¹ . The opposing portion 40 preferably insulates the internal volume of the box 23 from the remainder of the conduit 21 where other electrical conductors may then run.

According to variants of the embodiments shown in FIG. 6 and 7, the core R of the elastically deformable feet 21 carrying pins 38 to ^the bottom 36 of the box 23 is provided.

Each of these elastically deformable shoes 39, sequentially counted from the core R, has a resilient member 56 that is adjacent to the bottom 36 of the box 23 and separated from it by two slots 58, approximately parallel to each other, and at right angles to the resilient member 56 and integral. with it a fixed cell 59; that belongs to the side wall. 37 of the box 23 and is separated from it by the through slots 58 and carrying the associated pin 38.

In the embodiment shown in FIG. 6, the resilient member 56 runs radially.

In the variant embodiment shown in FIG. 7, it extends first radially and then circularly about a quarter of a circle, allowing to increase its length.

In both cases, the rigid member 59 is reinforced by a columnar extension in the central region and has a bore 52 at its upper end as mentioned above.

In both cases also continuously circular portion 40 ¹ upper part of the side wall 37 box 23 is a continuation of the corresponding part of the lower portion of the side wall 37 and is circularly positioned between slots 58 and in some places it is reinforced by reinforcing ribs 60 emanating from the collar of the 54th

According to a variant of the embodiment shown in FIG. 8, the pins 38 on this box 23 are slidably mounted parallel to its bottom 36.

They form practically separate portions of the box 23 and, for guidance thereof, have a continuously circular portion 40 * of the upper part of the side wall 37 of the box 23, which, as before, forms a single unit with the rest thereof.

To insert the pins 38 into these recesses from the inside of the box 23 outwards.

To limit this engagement, the pins 38 have pins 62.

occurs protruding

In the embodiment shown, the bore 52 is on them.

According to a variant of the pin 38 of the embodiment shown in FIG. 9 are rotatable on the box 23, each about the axis A shown in FIG. 9 is a dashed line that is substantially parallel to the bottom 36 of the box 23.

The remainder of the arrangement is, as in the embodiments shown in FIG. 6,7 and 8, essentially the same as described above.

According to a variant of the embodiment shown in FIG. 10, which is derived from the embodiment shown in FIG. 1 to 5, the box 23 has two stations P side by side for accommodating two devices 10.

The arrangement remains of the same type as described with reference to FIG. 1 to 5.

However, at the coupling between the two stations P, the side wall 37 has a continuous portion 40 ¹ which is rigid and connects two posts 40, each of which emits an elastically deformable shoe 39 carrying a pin 38.

In addition, at this connection, the two stations P are separated from one another by a partition 63, to each of which surfaces abuts the post 51 ¹ . having a bore 52 at its upper end.

In an embodiment with two stations P, the arrangement may be in addition to the type described with reference to FIG. 1 to 5, of course of the same type as described in connection with FIGS. 6 to 9.

The invention is not limited to the embodiments described and illustrated, but encompasses all variants of embodiments and / or combinations of their various elements.
