Description

Technical field

This invention relates to a barrier, in particular which can be used for infrastructures or constructions and preferably for separating lines of communication, such as railways, roads or motorways, from the surrounding environment.

Background art

There are prior art barriers for separating lines of communication, such as railways, roads or highways, from the surrounding environment, which comprise longitudinally spaced uprights along the direction of extension of the barrier and which support corresponding panels, and wherein the respective upright is normally configured with an I-shaped cross section having corresponding end flanges.
In the prior art barriers, such as known from JP 2001 279621 A , the means for connecting the panels to the respective upright have problems relating to the possibility of making, in an easy fashion, barriers in which the panels superpose the uprights, to allow an advantageous and improved appearance, in particular covering, or concealing, the presence of the supporting uprights of the barrier, at the same time maximising the surface of the panels of the barrier, with obvious advantages in terms of soundproofing and consequent optimising of the acoustic insulation.
Furthermore, the need is felt for barriers with systems for connecting the panels to the respective uprights, which are quick and easy to prepare and, in any case, flexible to use.

Disclosure of the invention

This invention therefore proposes a new solution as an alternative to the solutions known up to now and, more specifically, proposes to overcome one or more of the above mentioned drawbacks and/or problems and/or to meet one or more of the needs felt in the trade or inferable from the above.
It is accordingly provided a barrier, in particular for infrastructures or constructions, preferably for separating lines of communication, such as railways, roads or the like, from the surrounding environment, as defined in claims 1 and 15.
In this way, it is possible to achieve a fast and easy assembly of the barrier.

In practice, the means for gripping the connecting means 15 are designed to grip, according to the first preferred embodiment, a flange 12 shaped in the form of a plate flat, that is, a flange 12 in the shape of a "C", as described for the second embodiment of the connecting means 15 described above.
According to a third preferred embodiment of the connecting means 15, they are also designed to grip a corresponding flange 12 with a round shape, in particular tubular.
For that purpose, as may be inferred from Figure 6, opposite hook-shaped portions 351, 351 wrap around a circumferential stretch of the round portion 12 of the upright and have a corresponding curved shape.
In practice, the first and second hook-shaped portions 351, 351 are defined by a tubular body 350 open behind in 351', which surrounds the round body 12 and is integral with the connecting portion of the connecting body 15, which supports the insertion means inside the respective seat of the panel means.

More specifically, the connecting portion 155 and the gripping portion 151 are made, or defined, by a suitably shaped single portion or plate.
The connecting portion 155 extends transversely, in particular horizontally in use, and is in the form of a corresponding flat plate element from the front end of which extends the insertion portion 157, preferably positioned vertically in use.
From another viewpoint, the connecting means 15 comprise means for connecting to corresponding panel means 13, labelled 157, and connecting means 151, 151, in particular for gripping the corresponding upright 10, that is, the corresponding flange 12 of the upright 10.
It is defined a connecting portion 155 which extends between, and joins, the means 157 for connecting the corresponding panel means 13, that is, the insertion portion 157 in the seat 17 of the panel means 13, and the means 151, 151 for connecting, in particular for gripping, the upright 10.
As illustrated, as may be inferred from Figure 4B, the insertion portion 157 has a first and a second flange 157a, 157b.
More specifically, as may be inferred from Figure 4B, the insertion portion 157 has a respective flange 157a, which extends upwards from the connecting portion 155.
Further, the insertion portion 157 has a respective flange 157a, which extends downwards from the connecting portion 155.
Advantageously, the insertion portion 157 is in the form of a respective flat plate, in particular quadrangular in shape, preferably rectangular in shape, which extends transversely, in particular horizontally.
The result is that the connecting means 15 are substantially in the form of a body which has a cross section with a configuration in the general shape of a "T".
The insertion portion 157 defines a rear face 157p designed to engage with an opposite face of the seat 17 of the panel means 13.
Moreover, the insertion portion 157 defines a front face 155a designed to engage with an opposite face of the seat 17 of the panel means 13.

As shown in particular in Figure 4B, the seat 17 has an opening 170, in particular as illustrated a rear opening, for the passage of the connecting means 15, especially for the connecting portion 155, into the connecting seat 17.
Advantageously, the connecting means 15 are designed to retain, simultaneously, a first and a second barrier panel 13, 13, in particular a first and a second barrier panel vertically superposed on each other.
As illustrated, advantageously, the connecting seat comprises a first and a second respective seat, or half-seat, 171, 172 of panels 13, 13 adjacent to each other, in particular superposed over each other.

In practice, the panels 13, 13, in use, that is to say, in the superposed condition, have the respective seats 171, 172 for the connecting means 15 which are facing each other and define an opening for inserting the connecting means 15 in the respective upright, or for the connecting portion 155 of these.
In practice, for assembling the barrier it is simply necessary to position a first lower panel 13, inserting on the upright the respective connecting means, or body, 15, in such a way as to insert the insertion portion of these inside the upper seat 171 of the panel already positioned, and then positioning the upper panel 13 in such a way that the seat 172, provided at the lower end of this panel, which is positioned at the top, inserts above, that is, encloses, the insertion portion 157 of the connecting means 15.
This is all done in an extremely quick and easy fashion without having to define, in advance, the zones in which the connecting means must be set up and without having to operate inside the flanges of the upright for fixing the panel to the upright.
As may be inferred, the respective seat 17, 171, 172 of the respective panel extends horizontally, that is to say, along the main and longitudinal direction of extension of the panel 13.
In practice, the seat 17, 171, 172 extends preferably for a short horizontal or longitudinal stretch of the respective panel.
Moreover, the respective seat 17, 171, 172 extends vertically, or in height, in particular for a stretch less than the longitudinal or horizontal length of the same seat.
As illustrated, the respective connecting seat 171, 172 has an engaging and retaining rear wall 171 p, 172p for the insertion means 157.
Moreover, as may be inferred in particular from Figure 4B, the respective connecting seat 171, 172 has a respective bottom wall 171f, 172f and a respective front wall 171 a, 172a, which is opposite the corresponding rear wall 171p, 172p.
In practice, the front and rear vertical walls of the respective seat 171, 172 extend perpendicularly to the respective horizontal bottom wall.
In practice, the bottom wall of the upper seat 172 defines, basically, the top wall of the seat 17 formed in its entirety by the half- seats 171, 172.
Advantageously, the connecting means, or body, 15 are designed to retain, simultaneously, a first, a second, a third and a fourth panel 13, in particular in pairs of panels vertically superposed and placed alongside each other, as may be easily inferred from Figures 4B and 4C.
Advantageously, the connecting seat 17 comprises a first and a second pair of respective seats vertically facing each other 171, 172 of vertically superposed panels, the pairs of seats 171, 172 of vertically superposed panels being placed alongside each other.
The insertion portion 157 has respective transversal or horizontal flange portions, which are designed to engage relative connecting seats of panels placed alongside each other, in particular horizontally placed alongside each other.
Advantageously, the respective seat 171, 172 of the respective panel is open at the top or bottom, that is to say, it emerges at an upper or lower edge of the corresponding panel.
Moreover, the respective seat 171 of the respective panel 172 is also open at the lateral edge of the panel.
In practice, the seats 171, 172 open, as well as above or below, to the side of the panel, that is to say, they emerge at a side edge, or face, of the corresponding panel.
Advantageously, the respective panel 13 has a rear edge, in particular at the respective upper or lower edge of the panel, the rear edge leading into the respective connecting seat 171, 172 and being withdrawn relative to the edge, in particular at the top or bottom, of the corresponding panel 13 to define, in use, that is to say, with panels superposed, a corresponding opening 170 for passage of the connecting means 15, that is, for the respective connecting portion 155.
As shown, the above mentioned Figure 4B, the respective panel 13 has a metallic supporting, or outer, structure which can be suitably shaped to define a corresponding seat 171, 172 for receiving the means 15 for connecting to the upright.
More specifically, the metallic structure, preferably made of steel, is designed to support a corresponding transparent panel, that is to say, to encase corresponding noise insulation means or elements.
Obviously, as illustrated in Figure 7, the seats 171, 172 could be provided at the upper and lower zone of identical panels, that is to say, having an outer metallic support structure, which houses inside a corresponding acoustic insulation body.
As illustrated in Figure 8, the connecting seats 171, 172 are also provided with corresponding barrier panels 13, 13 made from corresponding concrete.
In the preferred embodiment, the connecting seats 171, 172 are made directly in the corresponding concrete material and are in the form of corresponding grooves, or recessed cavities, which open onto the upper and/or lower edge of the corresponding panel, as well as the corresponding lateral edge thereof.
Figure 9 illustrates a situation in which the connecting means 15 connect together panels made, respectively, of concrete and a metallic covering, or supporting, structure, showing the advantageous flexibility of use of the connecting means 15.
Advantageously, according to a second preferred embodiment of the connecting means 15, illustrated in Figures 10 and 11, they comprise first and second distinct parts 15', 15", the first and second parts of the connecting means being preferably, as illustrated, placed side by side and slightly spaced from each other, that is, they have respective opposite edges 159', 159" which are slightly spaced from each other, in particular positioned at panels placed alongside each other. Labels 13', 13' in Figure 11 denote the opposite edges of the panels placed horizontally alongside each other.
As illustrated, each part 15', 15" of the connecting means has a cross section in the general shape of a "T" and is preferably made of suitable metallic material.
In practice, advantageously, the first and second distinct parts 15', 15" comprise a respective hooked-shaped element, or portion, 151', 151" which are opposite each other and designed to grip the respective upright, that is to say, the opposite lateral edges of the flange of the corresponding upright.
Also, advantageously, the first and second distinct parts 15', 15" comprise respective means, or vertical plate, 157', 157" for inserting in the connecting seat 17 of the panel means 13, the insertion means being connected to the gripping means 151', 151" by corresponding connecting means, or portion, 155', 155", substantially similar to that described with regard to the first preferred embodiment of the connecting means 15.
Figures 12 and 13 illustrate a third preferred embodiment of connecting means of corresponding panels 13, 13.
In the third preferred embodiment of the connecting means, the connecting means 451 are made as one with the respective upright of the barrier, and in particular with the respective flange 12 of the upright.
More specifically, the connecting means 451 comprise a plurality of connecting portions 451, which are vertically distributed, in particular, and equispaced from each other, on the respective upright, preferably centrally to the respective flange 12 of the upright.
As illustrated, the connecting portion 451 extends forwards from front face of the flange 12 of the corresponding upright 10, that is to say, it extends in front of the upright 10 and has the general shape of a "L", the front flange of which extends upwards.
As may be inferred from Figure 13, the hook-shaped portion 451 inserts inside a corresponding seat facing downwards, denoted by the numeral 452, of a corresponding lower panel, whilst a fin protruding downwards from an upper panel, which is denoted by the numeral 453, inserts between the rear wall of the seat 452 and the opposite face of the upright, that is, of the flange 12 of the upright 10.
Advantageously, the connecting means 15 are designed to support the panel means 13 front of the respective upright 10.
As illustrated, the panel means 13 have respective side edges, which cover at least partly the respective upright 10.
In a further preferred embodiment of the barrier illustrated in Figures 14 and 15, the connecting means 15, which are identical to those of the first preferred embodiment, are used both on the front flange and on the rear flange, respectively 12 and 14 of the upright, in order to retain corresponding panel means which, however, comprise solely of shaped metallic covers, or plates, defining respective seats similar to those of the embodiments of panels described above.
The panel means or rear or front covering elements are labelled 513 in the figures.
More specifically, the seats 517 consist of a respective lower half-seat of the lower panel or covering and a matching upper half-seat of the upper panel, or covering.
There are also, labelled 514, upper covering means, in the form of a respective flat sheet having respective lateral retaining flanges, which face downwards and are designed to be inserted between the respective seat of the lateral covering element 513 and the element for inserting and retaining the connecting means 15.
According to another version of the further preferred embodiment, as illustrated in Figure 16, it may be inferred that the covering sheet elements 513 have only a receiving seat 617 located at the upper part of the respective panel, whilst below the panels there is a corresponding bracket in the shape of a "U", having fins facing downwards, and denoted by the numeral 619, the bracket 619 extending between covering elements, or panels, facing front and rear walls of the barrier.
The bracket 619 rests and grips corresponding elements for inserting the connecting means 15 positioned below.
According to a further preferred embodiment of a barrier, illustrated in Figures 17A to 17B, is possible to see how, in particular for the barrier panels made of concrete, the connecting seats 771, 772 of the connecting means are obtained using a corresponding profile 773, preferably metallic, in the general shape of an "L", comprising a first flange 771 p, 772p which defines the rear wall of the corresponding seat and a respective second flange 771f, 772f, defining the bottom of the seat and which extends with the respective free end, which is embedded inside the material of the panel, in particular of the concrete. The flange 771f, 772f defines corresponding means for connecting to the panel for the profile of seat 773.
In practice, the seats 771, 772, are at least partly made in the corresponding material, in particular in the concrete, which defines the respective front wall 771 a, 772a of the respective seat 771, 772, the seats opening at the upper and/or lower edge of the corresponding panel, as well as the corresponding lateral edge.
When the seat 772 opens at the upper edge of the upper panel of the stack of panels, forming means of infilling of the barrier, the connecting means, or element, 15 only have the portion, or flange, 157b which is directed downwards from the connecting portion 155 of the connecting means, or element.
Alternately, when the seat 771 opens at the lower edge of the lower panel of the stack of panels, forming means of infilling of the barrier, the connecting means, or element, only have the portion, or flange, 157a which is directed upwards from the connecting portion 155 of the connecting means, or element.
As may be inferred, the connecting means, or element, 15 can therefore comprise a single portion, or flange, for hooking or insertion inside the respective connecting seat of the corresponding panel.
Figures 18A and 18B illustrate a fourth preferred embodiment of the connecting means 15 for a barrier, which is substantially similar to the embodiment in Figure 5, being aimed at defining a connection for an upright flange shaped like a "C", which has been modified as illustrated in the embodiment of Figures 10 and 11, that is, in such a way as to have means for connecting the panel to the upright which comprise first and second distinct parts 815', 815", the first and second parts of the connection means being preferably, as illustrated, placed side by side and slightly spaced from each other, that is, having respective opposite edges which are spaced from each other.
As illustrated, each part 815', 815" has a cross section in the general shape of a "T" and is preferably made of suitable metallic material.
In practice, advantageously, the first and second distinct parts 815', 815" comprise a respective hooked-shaped element, or portion, 851', 851" which are opposite each other in use and designed to grip the respective upright, that is to say, the opposite edges, or fins, of the C-shaped flange 12 of the upright.
In practice, in a similar fashion to the second preferred embodiment shown in Figure 5, the respective connecting portion 851' and 851" also has a tooth-shaped portion 253, extending perpendicularly, that is, according to the direction of extension of the web 16 of the upright, for making an internal seat 254 for receiving an end fin 121 of the flange 12 of the "C"-shaped upright.
The tooth-shaped portion 253, 253 defines a corresponding face 251d for engaging the face inside the fin 121, whilst an opposite face 251e provides rear engagement for the portion 121 of the flange 12 which is "C"-shaped.
The tooth 253 of the respective part 851', 851" has a free end, or front face, 251f, which faces towards the insertion portion in the panel, that is, the connecting portion, in particular facing and spaced from the edge, or rear face 251 g defined by this connecting portion, to define a corresponding slot designed to allow the insertion of a corresponding lateral portion of the front panel 122 of the flange, in particular of the "C"-shaped profile.
In practice, the respective connecting portion defines a corresponding transversal bottom face 251g for the respective seat 254.
This defines means for gripping the end lateral fin 121 of the profile of the flange 12, which are, in particular, in the form of a corresponding seat 254 for inserting the end fin 121.
Preferably, the seat 254 is elongate perpendicularly and extends parallel to the core 16 of the upright, that is to say, to the end fin 121 of the core having the shape of a "C".
The elongate perpendicular seat 254 defines transversal retaining means for the connecting element, in particular for transversal retaining of this to the respective upright, in particular, to the flange 12 of the respective upright.
In practice, the connecting means 15 can be coupled to the upright in a slidable fashion along the longitudinal direction of the upright.
The connecting means 15 can be coupled to the upright in a slidable fashion along the front flange of the same upright.
The connecting means 15 can be coupled to the respective panel by inserting a respective connecting portion in a respective seat for receiving the panel.
Figures 19A and 19B illustrate a fifth preferred embodiment of connecting means 15 for a barrier, which are in the form of connecting means 15 which are adaptable, in particular selectively adaptable, to the respective panels and uprights to be connected, in particular adaptable to various configurations of the same flange 12 of the corresponding upright.
From another viewpoint, the connecting means 15 for a barrier are equipped with means designed to selectively modify, or adjust, the distance between the means, or portion, for coupling the upright, that is, to the flange 12 of the upright, and the means, or portion, for insertion or coupling to the respective panel.
More specifically, the connecting means 15 for a barrier are equipped with means designed to modify, or adjust, the perpendicular position, or perpendicular distance, of the means, or portion, for coupling the upright, that is, to the flange 12 of the upright, and the means, or portion, for insertion or coupling to the respective panel.
More specifically, advantageously, in this fifth preferred embodiment of the barrier, the connecting means 955, between the means for gripping the upright 951 and the means 957 for inserting in the respective connecting seat of the panel 13, comprise a respective rod 955a having respective means 955b, 955c for retaining the respective gripping portion 951, the retaining means 955b, 955c being movable and positionable along the rod 955a.
More specifically, the rod 955 is in the form of a screw, threaded at least at the free end zone, extending perpendicularly to the panel 13 into a corresponding transversal and vertical plate 957, defining the means for inserting inside the seat of the corresponding panel, and at the opposite end of the screw there are means 955b, 955c, in particular a nut and lock nut, which are designed to fix the above-mentioned gripping means 951 of the flange of the upright.
In practice, as may be inferred, the extension screw 955 has a large retaining head 955d inside a corresponding seat of the plate 957 for insertion in the seat of the panel, the plate 957 is extending, as illustrated, preferably, vertically.
The screw 955 supports at its free end corresponding nut and lock nut 955b, 955c designed to retain a transversal portion 951 a of the means 951 for connecting the flange of the upright, with the screw 955, which passes through a corresponding hole provided in the connecting portion 951 a.
In turn, the means 951 for coupling the upright comprise respective means for gripping the upright, in particular the flange 12 of the upright, which preferably can be, as illustrated, in the form of a corner or "L"-shaped profile, suitable for gripping, in particular, a corresponding fin of a "C"-shaped upright profile, which could, however, also be made in any suitable manner, especially in the form of a simple transversal plate suitable for fastening a corresponding end of a flat flange 12 of an upright having a corresponding "I" shape.
In practice, the corner or L-shaped profile for gripping the upright has a transversal portion 951a and a perpendicular portion 951b, extending from the end of the transversal portion, which are designed to engage the free end of a fin 121 of a flange 12 of the upright.
More specifically, the perpendicular portion 951 b extends on the inside of the fin 121 of the flange of the upright.
By suitably operating the nut and locknut 955b, 955c, it is possible to conveniently move the gripping means 951 along the rod 955a and suitably lock the flange of the upright 12.
The connecting means, or element, 15 substantially provide slidable joints which do not limit the panels to a predetermined position, but which adapt them to the position that the panels actually have in use.
In practice, means, or element, are obtained which have an extremely flexible use and which are particularly suitable for allowing the setting up of barriers with particularly advantageous tolerances.
In practice, this avoids the use of fixing devices between panels and uprights of the barrier which must be positioned in a stationary fashion.
The invention described above is susceptible of industrial application. It would be obvious to one skilled in the art that several changes and modifications can be made to the invention without departing from the scope of the claims. It is also easy to imagine further embodiments of the invention comprising one or more of the features described herein. Moreover, it will be understood that all the details of the invention may be substituted for technically equivalent elements.
