Definitions

  • the subject of the present invention is a sectional structure for the wall mounting of electrical devices, comprising a support frame which is intended to be fixed to the wall and has a seat for the mounting of the devices, the seat containing at least one switching device having a body housing its electrical contacts, a button being associated with the body, on the opposite side to that corresponding to the wall, and acting on the contacts by means of a pivoting movement.
  • switching device or, more simply, switch is intended to indicate generally two types of electrical device: simple, single-pole, contact-breaking switches also known by the acronym SPST (single pole-single throw) and single-pole, contact-switching switches also known by the acronym SPDT (single pole-double throw).
  • SPST single pole-single throw
  • SPDT single pole-double throw
  • the definition electrical device should be understood in a broad meaning which includes, in addition to the switches already mentioned, wall sockets, push-buttons, keyboards and knobs for various applications such as the usual bells, thermostatic regulators or timing devices, light or sound indicators for alarm systems and the like, fuses, sockets for television aerials or for the connection of coaxial cables of other kinds, as well as anything else which may be used in electrical systems.
  • buttons in some markets, particularly European markets, they are required to have larger dimensions than those in use in other countries.
  • this involves, in practice, the need to introduce modifications to the switches, which results in the disadvantage of the need to differentiate between these products in batches intended for the various countries.
  • a known solution for meeting this need consists of the formation of the body of the switch, which is the portion housing the electrical components (contacts, terminals, etc.), with larger dimensions so that it fits the larger button which is mounted thereon by a snap-engagement of known type.
  • the aforementioned electrical components are nevertheless the same as those used in switches with standard dimensions and the space available inside the larger body is thus clearly underused; it should be pointed out that, in the prior art, according to a preferred embodiment, the body of the switch is formed with dimensions multiples of those corresponding to a normal device so that it can occupy a space corresponding to one or more devices in the seat of the frame in which it is housed, according to need.
  • the object of the invention is therefore to provide a sectional structure for electrical devices of the type considered at the beginning of this description, in which it is possible to use buttons having various dimensions without the adverse consequences which arise in the prior art described above.
  • this structure includes a frame 2 to be fixed on a wall and a cover plate 3 which is coupled to the frame by snap-engagement, in known manner.
  • a switch 4 is housed in a seat 5 in the frame 2, to which it is fixed releasably by resilient engagement means of known type which are therefore not described in detail in this description; these means are, in any case, provided both in the seat and on the body 41 of the switch and are visible, although not numbered, in Figure 1.
  • the switch 4 comprises a body 41 which houses its electrical elements (terminals, contacts etc.), not shown in the appended drawings, and a rocker element 42 which can perform a snap pivoting movement about an axis transverse the body; this rocker element is situated at the front of the body 41 when the body is fitted in the seat 5 in the frame, the rocker acting on the electrical elements in order to activate the electrical contacts of the switch.
  • the rocker element also acts as means for the fixing of a switch button 50; more precisely, the button 50 just mentioned is fixed releasably to the rocker element 42 by the snap engagement of ribs 53 and 43 formed on a projecting rim 54 and on a partition 55 of the former (see Figure 2) as well as on the principal sides of the latter (see Figure 1), respectively.
  • the face of the button 50 which faces towards the body of the switch is divided into two portions by the partition 55, the first portion being intended to be coupled frontally with the body 41 on the ribs thereof, whereas the latter has a bracket 56 which is intended to house a pin 61 of a fitting 60 for supporting the switch button.
  • This fitting is essentially an element of a shape similar to that of the switch-body half, having the same resilient-engagement mounting means as the latter, and occupying the same space in the seat 5; the pin 61 mentioned above is formed in an opening 62 disposed at the apex of a surface projection on the side of the fitting which faces towards the button 50 when the structure is in the assembled condition.
  • the pin 61 and the bracket 56 are in practice a hinge-like coupling which allows the button 50 to perform a rotary movement about the pin 61 (see Figures 3 and 4) but prevents relative translations which would move the button away from the fitting; moreover, by virtue of the resilience of the bracket which, like the cover 50, in a preferred embodiment, is made of plastics material, it is nevertheless possible to remove the button from the pin in order to disassemble the structure if necessary.
  • the fitting 60 and the switch 4 are mounted side by side in the seat 5 and the button 50 is engaged with the rocker element 42 to which it is fixed for the pivoting movement thereof; at the same time, the hinge-like coupling of the pin 61 with the bracket 56 provides a support for the button which is therefore supported in a balanced manner relative to the partition and can thus be pressed from the front at any point without danger of being detached from the rocker element.
  • hinge-like pin-bracket coupling does not obstruct the pivoting movement of the button together with the rocker element at this stage.
  • the structure of the invention achieves the object set at the beginning since it permits the use of buttons with larger dimensions without the need for appropriate modification of the structure itself or of the normal switching devices but, on the contrary, achieves compatibility with those already existing.
  • a button 50 of any width larger than that of a normal switch that is, a switch corresponding to the production standard may be selected, the switch nevertheless being able to be used as described in the example and thus mounted in a structure also of standard type; for this purpose, it is hardly necessary to indicate that it will be sufficient to ensure that the configuration defined by the partition 55 and by the projecting rim 54 of the lever 50 seen in the foregoing example, including the ribs 51, reproduces the shape of a standard button.
