Definitions
- the subject of the present invention is a system for the support, fixing and wiring of electrical components such as transformers, switches and lamps, particularly halogen lamps, the system being able, in particular, to offer a perfect leaktight seal fully complying with the current norms in the event of any accidental contact with water.
- the system relates to possible mounting on pre-drilled support plates which house the lighting components.
- the components of the system are preferably fixed and wired on a suitable metal section of appropriate dimensions, pre-drilled for the fixing of the components of the lighting system such as transformers and various other accessories and coupled with a second covering section by being slid into the second covering section which is made, preferably extruded, from plastics material and does not necessarily have the same dimensions as the aforementioned metal section, the covering section bearing a suitable inner lip which is rigid like the whole of the remaining portion for the fixing of the metal section and an outer, less rigid lip which, when squashed by suitable closure end elements can achieve a perfect leaktight seal, the system having two end seals made of plastics material ("gaskets") which can be fitted on the ends of the section and which are placed in abutment by means of the two end elements which, as well as squashing the entire system by means of suitable fixing screws fitted thereto and inserted in suitable locating seats thereof, also urge the seal into abutment between the end element and the covering section.
- gaskets plastics material
- Systems for the wiring of electrical components for the purposes in question are usually support and wiring systems formed by box-like elements which are produced essentially from a metal channel section of appropriate dimensions and the two lateral lips of which bear against the mounting element (for example, a support plate), two portions at the ends of its central portion being bent forming respective lips the outer sides of which contact the corresponding ends of the lateral lips, thus forming corresponding closure "ends" at both ends of the metal element.
- the mounting element for example, a support plate
- the object of the present invention is to provide a system for the wiring and support of electrical lighting components such as, preferably halogen lighting components, which can prevent all of the problems described above, ensuring a perfect leaktight seal, safe electrical insulation, and easy assembly, dismantling and/or maintenance thereof, as well as notably pleasing aesthetic attributes, particularly in the case of "visible" installations so that it can be used without requiring particular aesthetic covering solutions, the system finally also enabling the lengths of the support and covering sections to be selected in situ by adaptation in the most appropriate manner.
- electrical lighting components such as, preferably halogen lighting components
- a support and wiring element 1 which is preferably constituted essentially by a metal channel section of appropriate dimensions on which there are mounted by suitable fixing means the respective electrical components, such as a switch/socket unit 31 and a transformer 32 from which supply wires 33 for lamps 34 extend.
- the support and wiring element 1 is coupled, as shown particularly in Figures 1 and 3, with a covering element 2 constituted by a section which is produced by the extrusion of suitable plastics material and which, like the wiring support element 1, is channel-shaped but with internal dimensions suitable for housing the wiring and support element 1 which can be slid therein with its lateral flanges 11 bearing on two corresponding inner lips 21 which extend from the ends of the lateral flanges 23 of the covering element 2 and which are extended further outwardly by respective lateral lips 22 for bearing on the support surface 3 of the support plate 4 so as to achieve a perfect lateral seal.
- a covering element 2 constituted by a section which is produced by the extrusion of suitable plastics material and which, like the wiring support element 1, is channel-shaped but with internal dimensions suitable for housing the wiring and support element 1 which can be slid therein with its lateral flanges 11 bearing on two corresponding inner lips 21 which extend from the ends of the lateral flanges 23 of the covering element 2 and which are extended further outwardly
- lateral lips 22 are produced by various techniques for rendering them more resilient than the rest of the covering element 2, for example, by processes for the coextrusion of materials with different stiffnesses, etc.
- This assembly of the support and wiring element 1 fitted in the covering element 2 is placed, with all of the components which make up the lighting system, on a suitable support surface 3 such as that of a support plate 4, as shown by way of example in the drawings and referred to herein.
- two seals 6 are fitted on the ends of the covering element 2 and are urged into abutment against the ends of the element 2 by means of two end elements 5, thus being clamped between the ends of the element 2 and the closure end elements 5.
- the end elements 5 are constituted basically by substantially parallelepipedal caps having cross-sections practically complementary with that of the covering element 2, that is, such that the profiles of their internal surfaces are the same as that of the external surface of the covering element 2, each cap also being closed on its side which faces outwardly in use by an outer transverse wall 51 connected to the respective upper wall 52 (see Figure 1 and particularly Figure 2), as well as to the side wall 53 (see Figure 3), terminating at its free end a in lateral lip 54 which extends outwardly in order to bear on the support surface 3 whereas, on the side which faces the covering element 2 in use, the cap is closed by an inner transverse wall 55 (see Figures 1 and 2) disposed slightly inside the respective end so as to form a projecting edge 56 for engaging and adhering with its internal profile on a corresponding portion of the respective end of the covering element 2.
- two cylindrical, tubular elements 57 in the internal holes of which suitable screws V are inserted as described below (see Figure 1) for fixing to the support plate 4, extend inwardly from the upper wall 52 (see Figures 1 and 2).
- the end elements 5 are practically identical to one another and can be fitted on the ends of the covering element 2 so as to be symmetrically opposed.
- both the support and wiring element 1 and the covering element 2 are constituted by longitudinal sections, they can be cut to various lengths, thus achieving wide variability of application.
- a piece of suitable length is formed by cutting of the respective metal section to form the support and wiring element 1 to which the appropriate electrical components, such as a switch/socket unit 31, a transformer 32 and/or the like are fixed and these are then wired by means of suitable electrical wires F and the connections to the supply wires 33 of the lamps 34 and to the supply cable (not shown) are made.
- the appropriate electrical components such as a switch/socket unit 31, a transformer 32 and/or the like are fixed and these are then wired by means of suitable electrical wires F and the connections to the supply wires 33 of the lamps 34 and to the supply cable (not shown) are made.
- a piece of the respective plastics section of a length suitable for housing the entire electrical system to be protected is formed, again by cutting, thus forming the covering element 2 and, as stated, the support and wiring element 1 is inserted therein and positioned suitably therein, the supply wires 33 for the lamps 34 being inserted through the holes 41 for the mounting of the lamps 34, the switch/socket unit 31 (or other devices such as further sockets) at the same time being inserted in the respective hole (or holes) 42.
- the entire unit formed by the covering element 2 with the respective support and wiring element 1 is then positioned so as to bear on the support surface 3 on the upper portion of the support plate 4.
- respective seals 6 are fitted on the ends of the covering element 2, the seals 6 being constituted by walls made of a suitable elastomer and having an appropriate thickness and a profile suitable for covering the holes in these ends and, more precisely, an upper portion which follows the external profile of the end of the covering element 2 and a lower straight portion disposed between the ends of the upper portion.
- end elements 5 are fitted by being urged against the ends of the covering element 2, and are fixed to the surface 3 of the support plate 4 by suitable screws V which are inserted in the respective cylindrical, tubular elements 57 and are engaged in the body of the support plate 4.
- the covering element 2 is thus fixed to the support plate 4, its lateral lips 22 forming a seal on the surface thereof and, moreover, the seals 6 disposed at its ends are urged against its ends and against the surface 3 by the clamping action of the end elements 5, ensuring further sealing thereof in these portions.
