Definitions

  • the present invention relates to a raceway for distributing electric energy and similar services in civil use premises, of the type comprising a strip-like base to be fixed to a wall of a room, a strip-like cover to be removably engaged to said base in order to define at least one housing space therewith, a supporting element connected to said strip-like base and facing the inside of said housing space, and a plurality of electric conductors extending longitudinally and parallelly to each other at said supporting elements.
  • distribution structures have been recently widely used that, under use conditions, look like a common base or "skirting board" and that, disposed along the perimeter of a room, internally house the electric conductors relative to the services that are to be installed in the room.
  • electric and telephone systems and other similar services can be arranged in civil use premises without being it necessary to study in advance where the different apparatuses are to be installed because in this case a high degree of flexibility is ensured together with the possibility of adapting said distribution structures to all new requirements that may arise even in a later time, after laying of the raceways.
  • these distribution raceways are made of an insulating material, thermosetting resins for example, and consist of a strip-like base to be fixed to a wall, by gluing or screwing for example, and a cover to be removably engaged, generally by snap-fitting, to said base in order to define one or more housing spaces along which the electric conductors as well as the cables relating to the services to be installed in the room are caused to run.
  • raceways of recent construction the distribution of the electric energy takes place by means of three or more bare conductors pressure-fitted into longitudinal seats, disposed parallelly in side by side relation with respect to each other and formed on the raceway base.
  • Said seats are longitudinally provided with continuous access openings intended to enable, on the one hand, a forced fitting of the electric conductors, and, on the other hand, the optional introduction of contact elements for connection both to the mains power supplies and to the most different branching devices such as switches, sockets and so on.
  • connectors provided with spring contact elements in the form of a lamina are to be employed, said contact elements being spring urged through the longitudinal access openings so as to reach the electric conductors.
  • the lamina contact elements are endwise connected to electric wires that in turn are connected to the switch.
  • small springs are provided that act within each of the connectors housing the respective lamina contact element.
  • each electric conductor and the respective lamina contact element is substantially punctiform and therefore not very reliable, above all in the presence of high working temperatures and high humidity.
  • the fundamental object of the present invention is to substantially solve all the drawbacks of the known art by providing a raceway for distributing electric energy and similar services in civil use premises in which the connecton to the electric cables housed in said raceway can be carried out in a more reliable and functional manner as compared to the connections of the known art.
  • each of said conductors exhibits an anchoring portion rigidly connected to said supporting element and a wiring portion extending substantially perpendicular to said strip-like base.
  • a raceway for distributing electric energy and similar services in civil use premises is generally identified by reference numeral 1.
  • the raceway 1 can be widely used both in offices and in dwelling houses, each time it is necessary to distribute electric energy or provide cables for other services without carrying out boresome masonry operations.
  • the raceway 1 can be disposed in the region of the base perimeter of the walls in a room, in place of, or side by side with false door jambs, along walls and ceilings where it is necessary to distribute particular services at points raised from the floor.
  • the raceway can exhibit an external conformation of the "skirting" or "frame” type. In the last-mentioned case the raceway will have a reduced thickness so as to pass under wall cupboards, behind pieces of furniture, and be able to follow all types of path.
  • the raceway 1 consists of a strip-like base 2 made of electrically insulating material to which a cover 3 is detachably engaged.
  • the cover too has a strip-like structure defining with the base 2 one or more housing spaces 4.
  • a raceway having a single housing space 4 is shown
  • a raceway provided with two superposed housing spaces is shown, said spaces being separated by a rib 5 emerging from the cover 3 and extending longitudinally in a substantially horizontal plane.
  • the cover 3 is generally fixed by snap fitting to the base 2 by means of suitable mutually engaging extensions or ribs.
  • the substantially flat cover 3 laterally has curved edges 6, provided with cavities 6a into which respective swellings 7 carried by the base 2 of a substantially C-shaped cross section are engaged.
  • the strip-like base 2 can be fastened by means of screws or the like, to the walls of the room where the electric distribution system or other services are to be arranged.
  • Two or more electric conductors 8 are housed within the hollow space 4 of the raceway 1 and they extend longitudinally and parallelly to each other following the extension of the raceway 1 itself.
  • each of the raceways shown in the accompanying drawings three of said electric conductors 8 are always provided; however, it is possible to simultaneously use a greater number of said conductors.
  • particularly advantageous is the solution in which in a single raceway five conductors 8 disposed in mutual side by side relation are provided.
  • the central conductor may be used as a common earth conductor for the conductor pairs adjacent thereto.
  • the two conductors disposed to the right with respect to the centre conductor may work with a first voltage of 220 V for example, whereas the two conductors placed to the left with respect to the centre conductor may work with a second voltage of 380 V for example, so that said centre conductor acts as an earth conductor for both pairs without an additional conductor being required.
  • the electric conductors 8 are connected to a supporting element 9 integral with the base 2 and facing the inside of said hollow space 4.
  • said supporting element consists of a panel provided, at least at its ends, with spacing ribs 10 adapted to enable a correct spacing between the conductors 8 and the wall to which the base 2 is fastened.
  • spacing ribs 10 located at the ends of the supporting element are respective engagement grooves 10a for receiving by snap fitting auxiliary ribs 11 emerging at right angles from the base 2 and extending parallel to the conductors 8.
  • each conductor 2 exhibits an anchoring portion 8a (see Fig. 3) rigidly engaged to said supporting element 9 and a wiring portion 8b extending substantially perpendicular to the strip-like base 2, so as to advantageously offer a wide surface to which can be engaged the connectors for the branching lines or power sypply lines terminating at the electric conductor.
  • Each of the electric conductors 8 is obtained by successive bending operations starting from a ribbon, preferably made of copper, and has first and second ribbon-like portions 12 and 13, disposed symmetrically opposite to each other and rotated through 180° with respect to each other, at a longitudinal bending edge 14. In this manner, the ribbon-like portions 12 and 13 are mutually faced and substantially parallel to each other.
  • each of said portions 12 and 13 is then provided with a respective hooking lip 15, 16 forming a 90° bent relative to the ribbon-like portion.
  • the anchoring portion 8a defines with the wiring portion 8b a substantially T-shaped cross-section.
  • said anchoring portion is buried in the supporting element 9. Practically, during the production step, after the different electric contact elements 8 are made, the latter are disposed at the extrusion die by which the supporting elements 9 are formed. In other words, the connection between the electric contact elements 8 and supporting element 9 takes place directly during the extrusion of the supporting element, thereby ensuring a better and more precise positioning of the electric contact elements, a reliable and strong anchoring of the contact elements, and an important reduction in time when laying of the raceway occurs.
  • a longitudinal protection panel 17 may be provided to advantage and be arranged so as to cover said electric conductors.
  • the protection panel 17 is engaged in a removable manner and, depending on the cases, can be hooked directly to the electric conductors 8, as shown in Figs. 1 and 2, or to the supporting portion 9, as shown in Fig. 7.
  • the longitudinal protection panel 17 is cut whenever necessary in order to create access windows enabling the conductors 8 to be connected to branching lines leading to outlets and other branching devices or lines belonging to an external power line.
  • each electric conductor 8 at its wiring portion 8b is engaged by a clamp element 19 of a connector 20 terminating at a respective power line.
  • each clamp element 19 has a central body 21 from which two arms 22 and 23 extend at right angles; said arms are disposed symmetrically relative to each other and define an insertion seat 24 into which the wiring cable 8b of the conductor 8 engages.
  • the above mentioned arms 22 and 23 exert an elastic thrust action on the sides of the ribbon-like portions 12 and 13 of the electric conductor 8, so as to ensure a sufficient mutual-contact pressure.
  • the shape of the arms 22 and 23 of the clamp element 10 substantially matches the shape of the wiring portion 8b of the electric conductor 8, so as to define a relatively wide contact surface with said electric conductor, which surface is therefore capable of ensuring a very reliable and durable electric connection.
  • the invention achieves important advantages. It will be recognized, in fact, that since the wiring portion 8b of the electric conductors 8 emerges perpendicularly to the strip-like base 2, said conductors offer a wide surface on which the clamp elements 19 of each connector 20 can efficiently exert their clamping action, each time it is necessary to make a branching or an electric connection with power lines external to the raceway 1.
  • the contact area between the clamp elements and the wiring portion of the conductors is relatively wide and not substantially punctiform as it is, on the contrary, in the known art. This quality not only ensures a very reliable contact, but also enables the conductors and connectors to be submitted to a reduced wear at the region of mutual contact, in that arising of sparks or, what is worse, of flames is substantially averted.
  • the electric conductors disposed in the raceway may have a structure different from the one previously described in detail. They may for example have a structure similar to that of the clamp connectors, that is be provided with a central body fastened to the supporting element and two arms disposed symmetrically with respect to each other and defining an insertion seat into which a connector will be engaged, said connector in this case having a peg conformation.
