Definitions

  • the present invention relates generally to the covering which it It is usual to have any electrical equipment on the front.
  • such a covering usually comprises a plate, generally in the form of a frame, which is intended to be attached from the front onto a support forming a housing for the mechanism of the electrical apparatus concerned, or that, in the case of built-in electrical equipment, this support either directly a wall or any other surface of this type, either that, in the case of an electrical apparatus to be disposed projecting from such wall or on such a surface, this support is a housing which is itself report on this wall or on this surface.
  • the plate By its central opening, the plate gives free access to an organ central on which depends the use of the mechanism of the underlying electrical equipment.
  • this organ central is for example a tilting operating finger.
  • the central organ can have a different configuration.
  • the present invention relates more particularly to the case where, for satisfy such different configurations for the central organ of electrical equipment, it is planned to have, annually, around this central organ, between this and the plate, a peripheral organ, commonly known as a hubcap, shaped like a frame.
  • this hubcap When, voluntarily or involuntarily, this hubcap is subjected to a frontal mechanical shock, it transmits it completely to the underlying mechanism, at the risk of unacceptable damage to it.
  • the present invention generally relates to a provision making it possible to avoid this disadvantage, and, therefore, to save the mechanism of the electrical equipment.
  • a covering for apparatus electric of the kind comprising a plate, generally in the form of a frame, which is intended to be attached from the front to a support forming a housing for the mechanism of the electrical equipment concerned, with, in the opening central of this plate, on the one hand, a central organ, on which depends the use of this mechanism, and, on the other hand, an embellishment, which extends annularly around of the central organ, between the latter and the plate, this covering being of a generally characterized in that, between the hubcap and the plate, are provided support means, which, in particular, play a significant role perpendicular to the plate.
  • any frontal impact exerted on the hubcap is transmitted to the support of the assembly by the plate, without repercussion on the mechanism of electrical equipment.
  • the following dressing the invention advantageously hinders the mechanism of the apparatus electric, and it is thus advantageously protected.
  • the central organ itself presents at least locally an appendage, which projects laterally, and by which it is inserted between the hubcap and the plate.
  • this central organ when this central organ is an operating finger mounted tilting, it comprises, in diametrically opposite positions, one by relative to the other, two appendages, which aligned with each other, materialize its pivot axis, and which are both inserted between the hubcap and the plaque.
  • any frontal impact which this central organ could itself be the object is also transmitted to the support of the assembly by the plate, without repercussions on the mechanism of electrical equipment.
  • seals are provided, in particular between the hubcap and the plate, these seals also advantageously serve as shock absorbers during such a possible frontal impact.
  • the covering 10 comprises a plate 11, in the general shape of a frame, which is intended to be brought forward from a support 12 forming a housing 13 for the mechanism 14 of the electrical equipment 15 concerned, with, in the central opening 16 of this plate 11, on the one hand, a member central 18, on which depends the use of this mechanism 14, and, on the other hand, a hubcap 19, which extends annularly around the central member 18, between this one and the plate 11.
  • the support 12 is assumed, for example, to be a wall, in which the electrical equipment 15, or, more precisely, its mechanism 14, must be embedded.
  • the electrical equipment 15 is further assumed to be, by way of example, a switch, with, for central organ 18 controlling its mechanism 14, an operating finger mounted tilting.
  • This electrical equipment 15 also does not fall within the scope of this invention, it will not be described in all its details here, in particular with regard to its mechanism 14.
  • the central member 1 8 has, peripherally, an outline generally quadrangular.
  • the central member 18 has a rectangular outline, with rounded angles, but, instead of being straight, its longitudinal edges are slightly convex.
  • the plate 11 has itself peripherally, a generally quadrangular contour, and more precisely square, with rounded corners.
  • Its central opening 16 has a rectangular outline, with straight edges and rounded corners.
  • the hubcap 19, which is in the form of a frame, and which is complementary, to both, of the plate 11 and of the central member 18, has, therefore, in the form of illustrated embodiment, a rectangular outline with rectilinear edges along its outer periphery, and a rectangular outline with longitudinal edges concaves along its inner periphery.
  • the plate 11 is also overall planar, although its facade surface 22, that is to say its surface upper, may for example be more or less curved or curved.
  • the plate 11 For its attachment to the support 12, the plate 11 comprises, in each of its corner zones, for the passage of any fixing means, by example for the passage of a screw 24, as shown, a bore 25.
  • this drilling 25 occurs at the bottom of a well 26 capable of being concealed on the facade, i.e. level with the facade surface 22 of the plate 11, by a cover 27.
  • tranche 28 of this cover 27 is notched, so that it is difficult to extract.
  • support means 30, which, in particular, play a significant role perpendicular to the plate 11, that is to say substantially perpendicular to the plane along which it extends, and from which it follows that any frontal impact exerted on the hubcap 19 is transmitted to the support 12 of the assembly by plate 11.
  • these support means 30 comprise, on the plate 11, a rim 31, which borders the central opening 16 of this plate 11 on a at least part of its periphery, and on which the hubcap 19 bears, at least locally, from the front, either directly or indirectly.
  • the rim 31 which borders the central opening 16 of the plate 11 extends over the entire periphery thereof.
  • this rim 31 recedes by relative to the front surface 22 of the plate 11, and the hubcap 19 is therefore at least partly embedded in this plate 11.
  • the transverse sides 32 of the rim 31 have a width greater than that of its longitudinal sides 33.
  • the hubcap 19 bears directly on the rim 31 of the plate 11.
  • centering means are provided for positioning details of this hubcap 19 on this plate 11.
  • these centering means include at least two pins 35, which, projecting from the lower surface of the hubcap 19, each cooperate individually in interlocking with housings 36 provided in correspondence for this purpose on the rim 31 of the plate 11.
  • pins 35 are thus provided, in a rectangle, at the rate of two per transverse side 32 of the rim 31.
  • indexing means for a preferred orientation, in one direction or in the other, this hubcap 19 on this plate 11.
  • these indexing means include at least one pin 38, which, projecting from the lower surface of the hubcap 19, cooperates in fitting with a housing 39 provided in correspondence with this effect on the edge 31 of the plate 11, and, more precisely, on one of the sides transverse 32 of this rim 31, between two pins 35.
  • this seal 40 extends continuously under the central organ 18, more or less following the shape thereof, while being applied, by its peripheral edge 41, against the rim 31 of the plate 11.
  • the seal 40 has notches 42, for the passage of the legs 34 of the hubcap 19.
  • peripheral edge 41 it also has holes 43, for the passage of the pins 35 of the hubcap 19, and, in positions diametrically opposite to each other, two holes 44, for the passage of the pin 38 of this hubcap 19.
  • the central member 18 itself has, at least locally, a appendix 45, which projects laterally on one of its sides, and by which it is inserted between the hubcap 19 and the plate 11, so that, in the event that he would himself be the object of a frontal impact, this frontal impact would also be transmitted to the support 12 of the assembly by the plate 11.
  • the central member 18 being an operating finger mounted tilting in the embodiment shown, it comprises, in practice, in this form of realization, in diametrically opposite positions with respect to each other, two appendages 45, which, aligned with each other, each have, in hollow on their lower surface, a groove 46 with a rounded transverse profile, and, in correspondence, the rim 31 of the plate 11 has, locally, in protrusion on its upper surface, two ribs 47 with rounded transverse profile complementary to the previous one.
  • the appendages 45 of the organ central 18 extend parallel to its longitudinal edges, and they are generally curved, like round tiles.
  • the peripheral edge 41 of the seal 40 is itself generally tiled, and so it closes, locally, in alignment with each other, on its sides transverse, two arches 48.
  • the hubcap 19 has, on the lower surface of each on its transverse sides, in the median zone of these, on the one hand, the along its internal periphery, a notch 49, with rounded transverse profile, by which it covers the corresponding appendage 45 of the central member 18, and, on the other hand, along its outer periphery, beyond the notch 49, a notch 50, with rounded transverse profile, the amplitude of which is lower than that of the notch 49, and by which it covers the corresponding rib 47 of the plate 11 beyond the appendix 45 of the central member 18.
  • peripheral edge 41 of the seal 40 moreover, also, locally, projecting from its upper surface, four bosses 51, which, arranged in a rectangle, are intended to absorb the tilting of the operating finger formed by the organ central 18.
  • the seal 40 has, in its central area, at least one knockout 52, for the passage of the coach, not visible in the figures, that the central member 18 usually protrudes on its lower surface to act on the mechanism 14 of the electrical equipment 15.
  • two knockouts 52 are provided, which are arranged in diametrically opposite positions with respect to each other, of which only one is used according to the orientation of the central member 18, and therefore of the hubcap 19, compared to plate 11.
  • the hubcap 19 is integral with the plate 11 and thus forms with this a unitary sub-assembly whose assembly is in practice carried out in workshop.
  • screws 53 pass from behind the flange 31 of the plate 11, by means of holes 54 provided for this purpose in the zones angle of this flange 31, and these screws 53 are in screw connection with wells 55 provided in correspondence for this purpose on the hubcap 19, and, more specifically, on the lower surface of the legs 34 thereof.
  • central member 18 is inserted by appendages 45 between the hubcap 19 and the plate 11, it belongs by construction to the same sub-assembly than this hubcap 19 and this plate 11.
  • a seal 56 is provided between the plate 11 and the support 12, to oppose, together with the seal 40, upon any penetration of moisture into the housing 13 in which the mechanism 14 of the electrical equipment 15 intervenes.
  • this seal 56 is glued under the plate 11 all the way around it, to participate in the same subset that this plate 11.
  • the seal 56 In its corner areas, the seal 56 has holes 57 for the passage of the screws 24 ensuring the fixing of the assembly to the support 12.
  • this seal 56 is at less partially engaged in a housing 58 provided for this purpose recessed on the bottom surface of the plate 11.
  • the plate 11 can for example be made of metal or of material synthetic duly reinforced by a reinforcement, and, for example, by a fiber reinforcement.
  • the plate 11 advantageously collects everything any frontal impact to which the hubcap 19 may be subjected and / or the central organ 18, thus sparing the underlying mechanism 14 of the electrical equipment 15 concerned.
  • the support means 30 provided between the hubcap 19 and the plate 11 have, on the hubcap 19, a flange 59 by which this hubcap 19 overflows, at least locally, on plate 11.
  • This rim 59 can intervene jointly with the rim 31 of the plate 11 or as a substitute for it.
  • the hubcap can also be just as well bear indirectly on this plate, via a any intermediate piece, the main thing being that, with regard to a possible frontal impact or more or less oblique, the plate is an obstacle between him and the mechanism of the underlying electrical equipment.
  • the electrical equipment concerned can just as well be projecting on such a wall, the support on which must be attached the corresponding covering then being formed by a case itself duly reported on this wall.
