Description

12575

  The present invention relates to a joining group for the composition of tubular structures supporting illuminating groups, in particular for the exterior. Currently, for the illumination of outside regions, illuminating groups are already known that can be composed but which have only a slight flexibility of use allowing only the realization of a limited number of group forms, especially if these these are of the type

"in a cluster".

  In addition, the structures of the connecting groups of the tubular elements have a limited mechanical rigidity, which is why it is not possible to arrange the illuminating bodies strongly cantilevered with respect to the support column, and they have other notable limitations regarding the configurations of the illuminating groups

that we can get.

  The object of the present invention is to provide a joining group for the composition of tubular structures supporting illuminating groups capable of eliminating the drawbacks mentioned in this

who is before.

  These goals are achieved by a joining group for the

  assembly of tubular structures comprising at least one fixed tubular element and at least one tubular element supporting an illuminating body and removably connected to the fixed tubular element, characterized in that it comprises at least one junction element configured in box having two opposite lugs and at least two other box-shaped junction elements, each having at least one

  handle, one of the two handles of the junction element with double handle

  partner at the handle of one of the other junction elements to contribute to forming a first clamping ring of the elements themselves against the fixed tubular element, the other of the two loops of the box junction element associating with the handle of the two other connecting elements by contributing to form another ring of clamping elements against

  the tubular element supporting an illuminating body.

  The advantages obtained by means of the present invention

  exist in the fact that we can compose illuminating groups according to

26 2575

  many fancy configurations, especially of the cluster type.

  In addition, the possibility of supporting each illuminating body of

  group with a significant overhang facilitates the adoption of dimensional bodies.

important.

  Finally, the remarkable flexibility of use makes it possible to position each illuminating body at various heights along the support column,

  with significant advantages from the point of view of the technique of

  rage. The invention is explained in more detail in the following, with reference to the accompanying drawing which represents an embodiment thereof: FIG. 1 is a front elevational view of a connecting element of the type that can be used for the embodiment an enlightening group with one or two bodies; Figure 2 is a sectional view along II-II of Figure 1

  The joining group for the composition of tubular structures

  of support for illuminating groups consists of: -

  an element of the type that can be used for producing an illuminating group and one or two bodies that will be referred to simply as "one or two elements" in the following; an element of the type that can be used for producing a three-body illuminating group, which will be referred to simply as "three-element" in the following: an element of the type that can be used for producing a four-light unit a body which will be designated simply in the following by the expression "element with four" - a first and a second half-ring clamping;

  a reducing ring and a ridge element.

  Referring in particular to Figures 1-3, the one or two element, generally designated by reference numeral 10, is constituted by a box-shaped hollow body 11 of parallelepipedal shape made of aluminum alloy. The front portion has a first handle 12 whose radius

  coincides with that of the fixed tubular element, surmounted by a half

necklace 14.

  Laterally relative to the handle 12 is provided a pair of abutment planes 15, each having respectively a projection 16 and a groove 17. As well as pairs of holes 22 and 23 respectively threaded and through. The rear portion which is opposite the front portion also comprises a second handle 18 of dimension

  less than that of the first loop 12.

  Laterally with respect to the handle 18 and along the edges of the box body 11 are provided seats 19 of reduced thickness in

  of which ends a pair of conical projections 20 com-

with tapped holes 21.

  Referring in particular to Figures 4-7, the three-member, which is indicated overall 24, is also constituted by a hollow body box, substantially parallelepiped and aluminum alloy. The front portion comprises a first loop 26, whose radius coincides with that of a tubular element 13, surmounted by

a half-necklace 27.

  Laterally with respect to the first loop 22, there is provided a pair of abutment planes 28, converging in the center of the first loop 26 and each comprising a projection 31 and a groove 32, as well as a

  pair of tapped holes 29 and a pair of through holes 30.

  The rear part which is opposite to the front part also comprises a second loop 33 of smaller size than

26 2575

  of the first handle 26. Laterally with respect to the handle 22, along the edges of the box body 25, are provided seats 34 of lowered thickness, in correspondence of which are terminated three pairs of projections

  conically 35 oblique and having through holes 36 or tarau-

  37. Referring particularly to FIGS. 8-11, the four-member, generally indicated at 38, is similar to the three-member 24, the only difference being that some of its geometrical dimensions are reduced. and in particular the development but not the radius of the first loop 39 which corresponds to the handle 26; that's why we used

  the same references as those of the element with three illustrated above.

  Referring particularly to Figures 12-14, the first half

  The clamping ring, indicated as a whole at 40, consists of a box-shaped aluminum alloy body, describing a loop 48 of radius equal to that of the tubular element 13 and terminating in a pair of planes. stop 41 having on their side a pair of through holes 42, a pair of tapped holes 43, a projection 44

and a groove 45.

  A half-collar 46 and a pair of lightening grooves 47 com-

fold the half-ring 40.

  With particular reference to Figures 15-17, the second half

  clamping ring, indicated generally at 49, is constituted by a box-shaped hollow body 52 made of aluminum alloy, with a shape in

plan in "C".

  The front end comprises a pair of lowered edges between which is included a handle 51 of dimension equal to that

  Inside the box-shaped hollow body 52 are provided three parallel and coplanar conical projections 53, traversed by through-holes 54 of which the one designated at 55 is disposed centrally.

and tapped.

  Referring particularly to Figure 18 for the formation of a body illuminating group, the fixed tubular member 13 is assembled to a tubular member supporting an illuminating body 56 by interposing a one or two element between the two elements. so that the first loop 12 partially surrounds the tubular element 13 while the second

26 2575

  handle 14 partially surrounds the tubular element 56. The planes 15 of the element 10 meet the planes 41 of the first clamping half-ring by means of screws 57 which are arranged in the pairs of holes 22, 23 and 42, 43. The loop 48 of the element 40 collaborates with the first loop 12 of the element 10 to enclose the tubular element 13. The low-thickness seats 19 of the element 10 cooperate with the corresponding edges of the second half-ring 49 and the cove 51 of the latter collaborates with

  the second loop 18 of the element 10 for fixing the tubular element 56.

  Screws 58 pass through through holes 54 of the second half-ring

  49 and at the same. time in the through holes 21 of the element 10.

  An earthing screw 59 and the spring 60 associated therewith

  are arranged in the hole tarauc, é 55.

  Referring particularly to FIG. 18, for the formation of a two-body illuminating group, a pair of elements 10 is used.

  The second handles 18 collaborate with the handles 51 of a pair

  half-ring 49 for supporting a pair of tubular elements 56.

  According to the same modality, it is possible to obtain groups with three illuminating bodies using three elements 24 (see FIG. 20) or groups with four illuminating bodies using four elements 38 (see FIG.

Figure 21).

  Referring in particular to Figure 22, in the case where the

  fixed tubular member 20 has - a diameter less than that provided, it is possible to interpose between the elements 10, 24, 38 and élérpents

  fixed tubular 13 a reducing ring 61 made in two identical halves

  63 which can be connected by means of screws 64 and constituted by a pair of half-flanges 65, joined by ribs 66 and delimited by edges 67 which are arranged at the time of assembly in the grooves

  12, 26, 39 of the elements 10, 24, 38.

  Referring in particular to FIG. 23, the joining group for the composition of tubular structures according to the invention further provides a ridge element 62 comprising a frustoconical element 68 whose first end 69 is intended to cooperate with an illuminating body (not shown) while the second end 70 is connected to a flange 71 provided with a conical portion 72 which can be threaded onto
