Definitions

  • the present invention relates to a shunt and support device for lighting elements, in particular low-voltage electric installations.
  • conductor rods are often arranged to which one or more lighting elements are fastened at shiftable locations depending on requirements, for example with the aid of locking clamps.
  • Said lighting elements are generally engaged to the locking clamps or similar arrangements by ball-and-socket joints through which the feed wires pass.
  • known devices often do not offer stable positionings for the lighting elements, namely said elements are subjected to important deviations from their original location if they are bumped into, even slightly.
  • the general task: underlying the present invention is to devise a shunt and support device for lighting elements capable of substantially eliminating the above drawbacks.
  • Another important object is to provide a shunt and support device enabling both a firm and steady engagement of a lighting element to a conductor rod and an easy modifiability of the positioning of the same lighting element along widely differentiated orientations and directions.
  • a shunt and support device for lighting elements in particular low-voltage electric installations, which is characterized in that it comprises:
  • the shunt and support device for lighting elements in accordance with the invention has been generally identified by reference numeral 1.
  • It comprises a main box-shaped body 2 divided into two portions forming a shell and comprising one half shell 2a and a second half shell 2b.
  • auxiliary box-shaped body 3 Rotatably engaged to the half shell 2a at a cylindrical expansion 2c emerging outwardly of the half shell itself is an auxiliary box-shaped body 3 of substantially truncated conical form and exhibiting an internally-hollow threaded support connection 4 enabling coupling to a light element, a lamp for example, and passage of power supply cables for said light element.
  • First locking means 5 comprising a screw 6 provided with a head 6a located internally of the half shell 2a and a nut 7 buried in a substantially spherical knob enable the auxiliary box-shaped body 3 to be locked to the half shell 2a according to orientations at an angle to be fixed at will, about one axis of rotation 9 coincident with the longitudinal axis of screw 6.
  • a substantially tubular element 10 is located between the half shells 2a and 2b and within appropriate hollows in the form of a semicircle, which tubular element has a longitudinal axis 11 at right angles to the first axis of rotation 9 and adapted to define a through housing for the main box-shaped body 2 which is passed through by a rod-like element 12 provided with a pair of electric longitudinal conductors 13 at opposite locations on the surface thereof.
  • the rod-like element 12 substantially defines a self-bearing feeder line to which one or more shunt devices 1 can be applied.
  • tubular element 10 internally exhibits a pair of longitudinal slide guides 14 to be engaged in respective grooves formed in the rod-like element 12.
  • the longitudinal guides 14 therefore enable the whole device 1 to slide in the axial direction of the rod-like element 12 also defined by the longitudinal axis 11.
  • tubular element 10 can also rotate, in relation to the main box-shaped body 2, about a second axis of rotation coincident with the longitudinal axis 11 and it exhibits a circular expansion 15 fitted in a recess 16 formed between the two half shells 2a and 2b and adapted to prevent the tubular element 10 from axially sliding.
  • a pair of connecting terminals 17 provided with locking headless screws is arranged in the auxiliary box-shaped body 3 and can be engaged to electric contact elements 19.
  • Said contact elements comprise one element 19a connected to the half shell 2a and a second element 19b connected to the half shell 2b extending between the connecting terminal 17 and tubular element 10.
  • the tubular element 10 is provided with transverse slits in register with the longitudinal conductors 13, said slits being passed through by end portions 19c of the electric contact elements 19.
  • the end portions 19c have a concave edge 19d allowing the electric contact with the longitudinal conductors 13 to be maintained through a rotation of the main box-shaped body 2 about the tubular element 10 of about 45° in the two ways, and therefore through an overall rotation of about 90°.
  • Said end portions 19c define themselves said rotation by abutting against the longitudinal guides 14.
  • second locking means 21 adapted to clamp the tubular element 10 between the half shells 2a and 2b, and keep said half shells together in order to prevent the mutual rotation thereof about the second axis of rotation 11.
  • the locking means 21 is adapted to urge the electric contact elements 19 against the longitudinal conductors 13, while at the same time stopping the longitudinal sliding of device 1 along the guides 14.
  • the second locking means 21 comprises a locking ring 22 and a fork-shaped tie rod 23 the limbs 23a of which disposed astride of the tubular element 10, are engaged at first ends 23b to the half shell 2a by stop rings 24.
  • the fork-shaped tie rod 23 is provided with a second threaded end 25 emerging from the second half shell 2b and designed to be engaged to the locking ring 22.
  • the locking ring 22 After introducing the rod-like element 12 into the tubular element 10, the locking ring 22 being slightly unloosed, it is possible to make device 1 slide to the desired point along the longitudinal guides 14. After setting the angular position too of device 1 relative to the second axis of rotation 11, device 1 is fixedly locked through rotation of the locking ring 22. Said locking ring acts on the second half shell 2b and together with the fork-shaped tie rod 23 engaged to the first half shell 2a, causes said half shells to move close to each other so that they clamp the tubular element 10 preventing it from rotating.
  • the electric contact elements 19a and 19b as well are moved close to the longitudinal electric conductors 10 of the rod-like element 12 and therefore, in addition to powering the connecting terminals 17 to which the feeding cables of the lighting element are engaged, they also achieve a friction action preventing the device 1 from sliding in the longitudinal direction of the rod-like element 12.
  • knob 8 enables the auxiliary box-shaped body 3 supporting the lighting element to be fastened to the desired angular inclination.
