Complete Specification for the invention entitled:.
COUPLING UNIT FOR COMPOSING TUBULAR SUPPORT STRUCTURES FOR LIGHTING ASSEMBLIES The following statement Is e full description of this Invention, including the best method of performing it known to us I la COUPLING UNIT FOR COMPOSING TUBULAR SUPPORT STRUCTURES FOR LIGHTING ASSEMBLIES The present invention is concerned with a coupling unit for composing tubular support structures for supporting lighting assemblies, in particular for outdoor application.
At present, for lighting outdoor areas, modular lighting assemblies are already known per se, which however show a poor flexibility in use, in that they make it possible only a limited number of shapes to be accomplished for the same assemblies, in particular if such shapes are of the "in-bunches" type.
Furthermore, the structures of the tubular element coupling assemblies show a limited mechanical stiffness, so that positioning the lighting bodies with a considerable cantilever length relatively to the support pole is not possible, with a further considerable limitation in the configurations which can be obtained in the lighting assemblies.
The purpose of the present invention is to provide a coupling unit for the composition of tubular support structures for lighting assemblies, capable of overcoming the previously mentioned drawbacks.
The present invention, therefore, provides a coupling unit for the construction of tubular structures comprising at least one fixed tubular element and at least one further tubular element which supports a cantilever lighting body wherein the unit comprises: at least one hollow box-like primary coupling element having at least two part-cylindrical tubular-element engaging surfaces; and at least two hollow box-like secondary coupling elements each having at least one part-cylindrical tubular-element engaging surface wherein one of the part-cylindrical tubular-element engaging surfaces of one of the hollow box-like primary coupling elements cooperates with Vi LZI C~p C C lb one of the part-cylindrical tubular element engaging surfaces of another hollow box-like primary coupling element to form a clamping ring for a fixed tubular element or (ii) one of the part-cylindrical tubular element engaging surfaces of the hollow box-like secondary elements to form a clamping ring for a fixed or a further tubular element such that the tubular elements are held in substantial parallel relationship.
Preferably, the coupling unit has two primary coupling elements each with two element engaging surfaces; and two secondary coupling elements; with a first of the two element engaging surfaces of the first primary coupling element cooperating with a first of the two element engaging surfaces of the second primary coupling element to form a first clamping ring for clamping said first and said second primary element against said fixed tubular element, and with the other one of the element engaging surfaces of the primary coupling elements cooper-ating with the element engaging surfaces of the secondary coupling elements to form two further clamping rings for clamping the said primary and said secondary coupling elements against said two tubular elements each supporting a lighting body.
Preferably, the coupling unit has three primary coupling elements with two element engaging surfaces; and three secondary coupling elements; with a first of the three element engaging surfaces of the first primary coupling element cooperating with a first of the two element engaging surcaces of the second and third primary coupling element to form a first clamping ring for clamping said first, said second and said third primary coupling element against said fixed tubular element; and with the other one of the element engaging surfaces of the primary coupling elements cooperating with the element engaging surfaces of the secondary coupling elements to form three further U, '1
_I
ic clamping rings for clamping the said primary nd said secondary coupling elements against said three tubular elements each supporting a lighting body.
Preferably, the coupling unit has four primary coupling elements with two element engaging surfaces; and four secondary coupling elemewith a first of the two element engaging surfaces of the primary coupling element cooperating with a first of the two element engaging surfaces of the second and third and fourth primary coupling element to form a first clamping ring for clamping said first and said second primary coupling element against said fixed tubular element; and with the other one of the element engaging surfaces of the primary couL,ling element cooperating with element engaging surfaces of the secondary coupling elements to form four further clamping rings for clamping the said primary and said secondary coupling elements against said four tubular elements each supporting a lighting body.
Preferably the primary coupling elements comprise a hollow box-like body, whose front portion is provided with a first part-cylindrical tubular-element engaging surface surmounted by a half-collar, and, sideways, a couple of striker planes, each of which respectively has a tooth and a slot, as well as couples respectively screw-threaded and through bores, with the rear portion of said hollow box shaped body showing a second part-cylindrical tubularelement engaging surface, sideway- to which lower-thickness seats are provided, in correspondence of which at least a couple of conical projections having through bcres or screw-threaded bores end. Preferably the second coupling element concurring to form a first clamping ring comprises a first half-ring forming one part-cylindrical tubular-element engaging surface having a radius equal to the radius of the tubular element with said body comprising a couple of lighting hollows and half-collar with said body ending with a couple of striker planes having in their turn a couple of)0 a couple of striker planes having in their turn a couple of t ~i] Id through bores, a couple of screw-threaded bores, a tooth and a slot. Preferably the secondary coupling element compris-ing a hollow box shaped body having a "C"-shaped plan, with said body having at its ends a couple of smaller-thickness edges between which a one part-cylindrical tubular-element engaging surface is comprised, which can be associated with the part-cylindrical tubular element engaging surfaces, said body housing inside its interior three conical, parallel and r re t r": r a 3 4(9 6~b 2 -2co-planar protrusions through which bores pass and a bore of the secondary coupling elements is screw-threaded, is a through bore, and is engaged by an earthing screw pre-loaded by the relevant spring. It is further preferred that the unit furthermore comprises a reducer ring comprising two half-rings which are identical and jointable to each other, with said half-rings being constituted by a couple of halfflanges connected by ribs, and bounded by edges having a diameter equal to the diameter of the circle-arc-shaped hollow outlines, and also that the unit comprises a cone-frustum-shaped element which can be associated with the fixed tubular element, with said con-frustum-shaped element having a first end destined to cooperate with a lighting Sbody, and the second end being jointed to a flange provided with a conical portion which can be slid onto the fixed j tubular element and with a couple of protrusions constituting stop elements. Preferably the con-frustum-shaped element is clamped to the fixed tubular element by secondary coupling el-ments.
The advantages achieved according to the present invention consist in that lighting units can be composed according to many phantasy configurations, in particular of the "in-bunches" type.
Furthermore, the possibility of supporting each lighting body of the assembly with a considerable cantilever length facilitates the adoption of bodies with large overall dimensions.
Finally, the considerable flexibility of use makes CIl, it possible for each lighting body to bg positioned at different heights along the support pole, with considerable advantages from the view point of lighting technique.
The present invention is explained in greater detail in the following disclosure, with the aid of the drawings which represent an example of practical embodiment thereof.
