Description

SPECIFICATION Assembly of reticular, structural components The invention concerns an assembly for fittings for outside locations, such as gardens and others, which consists of trestle type reticular components with polygonal cross section, with longitudinal beams at the corners and slanting connection tension bars, which components form stanchions, brackets, arches and terminals, and of lighting elements that can be associated with the above reticular components.

In practice the reticular components can be trian gulartrestle type, formed by three longitudinal beams at the corners and by slanting wind bracing tension bars; these components are to be coupled by joints between the longitudinal beams in order to form vertical, horizontal and molded structures.

A basic element can be formed by an end plate solid to the coplanar ends of the longitudinal beams and made further solid to the stanchion by means of square gussets welded to the above plate and to the above longitudinal beams.

The longitudinal beams - placed at the vertices of a polygon in the cross section - have molded ends in order to fit, by means of junction couplings, the ends of the longitudinal beams of an adjacent component.

In order to allow the formation of cambers and broken line structures with limited mutual slant, joints are provided slightly different in length from one another and suitable for engaging the ends of two corresponding longitudinal beams of two com ponentsto be connected with each other to form an angle. These joints are of at least two different lengths in order to connect two adjacent compo nentsto form a relative angle of about 10 .

The invention concerns an assemblyforfittings based upon a reticular structure consisting of a plu ra lity of main components which is composed of junction couplings in order to form structures of different types and for different purposes and to achieve determined aesthetic configurations. Each main component, similar to girders, different in length, consists of at least three longitudinal beams 1 (Figure 1), placed at the vertices of a polygon in the cross section and connected with each other by slant tension bars 3 as wind bracings, which stiffen the so formed reticular structure; generally the longitudinal beams are cylindrical.

The ends of longitudinal beams 1 of a component are in the same transverse plane limiting each end of a main component; the ends of these longitudinal beams are molded in order to fit the ends of the longitudinal beams of an adjacent main component, junction couplings being provided for the concurring and coaxial ends of the longitudinal beams.

In addition to the above main components, that represent girders or portions of straight line girders, other elbow-shaped joint components of various types are provided, such as those 5 of Figure 1.

Even with many types of joint components, there are not many possibilities of combinations for forming structures different in shape, while on the other hand the joint components are too cumbersome and expensive to allow an adequate number of possibilities of giving shape to a complex reticular structure. The joint components involve for the most part the formation of very acute angles and up to the present time it has not been possible, for instance, to form centerings with limited curving, that is with considerable curving radius, or to form broken line structures with an equivalent development; instead, this is requested specially when the reticular structures we are considering have to be placed for outside rather than for inside fittings, where the development of the structure is generally square, in order to reproduce the development of the floors, walls and ceilings.This problem is solved according to what is shown in Figures 7 to 10.

According to Figures 2 to 6, a trestle type stanchion consists of three longitudinal beams 11 placed triangularly in the cross section (the triangle can be isosceles or even equilateral); the connection of the three longitudinal beams is trestle type formed by tension bars 13 slanting and orientated in the same way on the three fronts of the stanchion as defined by the three beams 11.

At the lower end of the stanchion thus formed, a base plate 15 is provided, shaped and orientated in most cases according to the triangular location of the beams 11. In order to stabilize the connection of the base plate to the stanchion, connection square gussets 17 are provided, welded - or connected in an equivalent way - with a corner edge to the relevant beam 11 and with the adjacent orthogonal corner edge to the plate 15. The stanchion thus formed is suitable for the outside reticular structures and for lamp-posts and similar.

According to what is illustrated in Figures 7 to 10, with 21,23 and 25 are indicated longitudinal beams belonging to two reticular components A and B to be connected with each other with a small mutual slant.

The reticular structure of each component A and B is completed by the tension bars, that is by wind bracings 27, that are suitably located both as to structural strength and from an aesthetic point of view. The longitudinal beams 21,23,25 are located at the vertices of an isoscles or equilateral triangle in the cross-section; the three ends of the longitudinal beams of each component A and B are placed in the same transverse plane.

The ends of the confluent longitudinal beams are connected with each other with a slant by using - see drawing - a couple of joints 29 having the same higher length and by using a joint 30 whose length is slightly lower, having both joints 29 to connect the corresponding ends of beams 21 and 23, while joint 30 connects the ends of the two beams 25.

The junction couplings to connect joints 29 and 30 with the ends of the longitudinal beams 21, 23, 25 will be suitably molded in orderto utilize the same moldings which serve for the connection of the structure reticular components or girders; these junction couplings will also consent the mutual slant between the longitudinal beams. The joints will be slightly curved or bent.

In Figure 8 the curve obtainable by joints 29 and 30 is provided in order to form the concavity at the side of the single longitudinal beam 25. By reversing the position ofjoints 29 and 30, that is by using a longer joint 29 to connect the longitudinal beams 25, 25 of the two components A and B and two shorter joints 30 to connect the longitudinal beams 21, 21 and 23, 23 of the two components A and B, it is possible to achieve an opposed curve, that is an opposed slant between components A and B, with respect to the slant shown in Figure 8.

Figures 9 and 10 show the design of a coupling suitable for connecting joints 29 and 30 to the longitudinal beams. In Figure 9, as an example, a joint 29 (with full circular section) is shown as connected to beams 21 (both with full circular section) by couplings 32. As mentioned above, couplings 32 shall be suitably molded in order to utilize the moldings for the mutual connection of the structure components. Both the ends of beams 21 and those of joint 29 show a molded extension, consisting in practice of a cylindrical portion 34B interrupted by an annular groove 34C. Essentially each coupling 32 consists of two semicylindrical parts 36 and 38 substantially symmetrical in respect of their coupling plane. These two parts can be coupled by bolt 40, perpendicular to the coupling plane; the head of the bolt is lodged in its proper seat as provided in part 38.Each part 36 and 38 shows on the plane coupling surface two hollows 42 molded in order to fit the molding of the extensions 34B and 34C; therefore in the connection of parts 36 and 38 two seats exactly corresponding to the two extensions are formed. Couplings 32, once bolt 40 is tight, create a rigid conection between each beam 21 and joint 29, both axially and angularly.

On Figures 11 to 13, item 51 indicates a nucleous, suitable to receive and to support a member to be combined with a terminal 52. From nucleous 51 rise according to the drawing - three appendixes 53 radially orientated and slightly slanting downwards (at least at the ends). These ends of the appendixes 53 are suitable for connecting by coupling 55 (Figure 13) the longitudinal elements 56 of a trestle type stanchion with wind bracings 57, which is shown in Figure 13 and rises from an anchorage base 59. The stanchion is designed as in other previous examples.

Terminal 52, formed by pieces 51, 53 is suitable for supporting a member serving several purposes including those of an aesthetic nature, such as a lamp 59 as shown in Figure 13.

The terminal is particularly suitable for usage in outside structures, when lamp-posts and similar are requested.

According to what is illustrated in Figures 14to 18, a bracket type support includes a nucleous 71, designed to receive and support the lamp member or similar that the said support is required to uphold.

From nucleous 71 extend two linear coplanar and symmetrical members 73,75, molded as shown in detail in Figure 18, while a third intermediate linear element 77, molded by two bends, develops on the symmetry plane of the assembly, below nucleous 71. Slanting wind bracings 78 connect the three elements 73, 75, 77. The terminal portions of elements 73, 75, 77 are almost mutually parallel and the ends 73A, 75A, and 77A of these elements are located in a plane vertically orientated in the arrangement of the assembly. These ends 73A, 75A and 77A are substantially placed triangularly (the triangle is isosceles, in particular, equilateral) and are connected with plate 79 suitable for the installation on stanchion 80, trestle type or similar.

Nucleous 71 can receive and support a lamp as indicated by L in Figure 17.

On the same stanchion 80, several supports, as described, can be fixed; a design of this kind is shown in Figure 18, where trestle type stanchion 80 develops with a triangular shape in the cross section and receives three bracket type supports, placed at the same level to form a triple lamp.

The drawing shows only one example of what has been designed 1, and can vary in shape and arrangement.
