Description
- The present invention refers to a fence structure adapted for obtaining any type of fence or fencing, usable for outdoor and indoor settings, civil and public.
- As is known, even if most fencing is made of iron, in mountainous areas and in many other contexts fences continue to survive as one of the most widely used fencing.
- Indeed, given that they are normally made of wood, a natural material, fences are rather well suited not only for mountainous landscapes, but also those environments where the contact with nature is particularly intense.
- For example, in recent years, fences have been quite widespread due to the increasing expansion of cycling paths.
- Indeed these paths require protection, such as fences, in order to prevent the accidental fall of people along escarpments, embankments, beds, footbridges, slopes, and so forth.
- Nevertheless, even if fences are universally appreciated for their limited environmental and landscape impact and for their perfect integration with the environment, they do not lack drawbacks.
- Indeed, it should be noted that fences require periodic maintenance, since with exposure to rain, sun and weathering agents the wood inevitably tends to be ruined and rot.
- While in less serious deterioration situations, it may be sufficient to use specific substances that allow remediating the damage sustained by the wood, if there are problems that compromise the overall stability and safety of the fence it is necessary to intervene in a more significant manner, operating a partial or total substitution of the damaged elements.
- In addition to a maintenance problem, however, there is another problem tied to the fact that the impregnating products - which the wood normally requires both in preliminary phase and during maintenance - in any case have a non-negligible impact on the environment.
- The task of the present invention is therefore that of attaining a fence structure which is capable of combining the advantages of strength over time with the aesthetic characteristics.
- In the scope of the abovementioned task, one particular object of the invention is to provide a fence structure that is very resistant to weathering agents, which allows preventing any typical problem of rot and maintenance of wood products, and which has a limited environmental and landscape impact.
- Another object of the invention is to obtain a fence structure which always has ordered positioning and uniform type, contrary to those made of wood which are often disordered due to sagging or deterioration.
- Further object of the invention is to obtain a fence structure which allows intervening on the territory with minimal polluting impact due to the absence of impregnating products, which the wood normally requires both in preliminary phase and during maintenance.
- Another object of the invention is to obtain a fence structure which is capable of solving the problem of poor night visibility, even if it is installed along paths that wind through areas with little illumination.
- Another object of the invention is to obtain a fence structure which, due to its particular structural characteristics, is capable of ensuring the widest guarantees of reliability and safety during use.
- Another object of the present invention is to obtain a fence structure such to comply with the requirements established by the current safety laws, such as for example MD 14/01/2008.
- Not least object of the invention is to obtain a fence structure which is simple and quick to install, also being advantageous from a merely economical standpoint.
- The abovementioned task, as well as the abovementioned objects and others that will be more evident hereinbelow, are achieved by a fence structure according to appended
claim 1.US2003222257A1 andUS4149701A disclose fence structures according to the state of the art. - Further characteristics and advantages will be clearer from the detailed description of a fence structure according to the invention, illustrated by way of a non-limiting example in the enclosed drawings, in which:
-
figure 1 is a perspective view of a fence structure according to the invention; -
figure 2 is a side view of the fence structure according to the invention; -

figure 6 is a partially sectional view of another example of installation of the fence structure according to the invention; -
figure 7 is a partially sectional view of a further example of installation of the fence structure according to the invention; -
figures 8 and 9 are, respectively, a side view and a top view with covers removed of another fence according to the present invention; -
figure 10 is a side view of a detail of an upright for the fence offig. 8 before a respective tab or ear has been bent; -
figure 11 is an enlarged-scale illustration of the profile of the upright offig. 10 at the height of the respective housing holes; -
figure 12 is an enlarged-scale view of a detail of the fence offig. 8 ; -
figures 13 and 14 are respectively a side view and a top view with covers removed of another fence according to the present invention; -
figure 15 is a side view of another fence according to the present invention; -
figure 16 is an enlarged-scale view of an upright for the fence offig. 15 . - With reference to the abovementioned figures,
reference number 1 overall indicates a fence structure. - The
fence structure 1 is essentially composed of a plurality oftransverse elements 2 supported byuprights 3 intended to be vertically fixed in the ground, or fixed to another support. - According to the present invention, in the
fence structure 1, theuprights 3 are constituted by first tubular metallic sections with substantially rectilinear axis, if desired closed on the upper part byremovable covers 4 which preferably have substantially conical form. - Alternatively, the
covers 4 can have different form, or they can be substituted by a saddle-like working (see, for example,figures 15 and 16 ) if thefence structure 1 also provides for an upper level oftransverse elements 2, in which case the upright oruprights 3 delimit a substantially U-shaped seat facing upward for the abutment of anend 2a or of a section of one or moretransverse elements 2. - In the present case, the
uprights 3 are made of COR-TEN steel. - It is important to underline that the selection of the use of the COR-TEN steel allows intervening on the territory with minimal environmental or landscape impact, without however sacrificing the strength characteristics and ease of assembly.
- In the present case, the
transverse elements 2 are instead composed of wood beams which are constrained to theuprights 3 by arranging them on one or more superimposed horizontal rows, possibly associatingvertical rods 7 therewith (seefig. 13 ) that are regularly spaced from each other. - It will nevertheless be clear to the man skilled in the art that, in accordance with the different needs, the
transverse elements 2 could also assume other configurations, which still fall within the scope of the present invention. - For example, the
transverse elements 2 could be constituted by second tubular metallic sections with axis that is substantially rectilinear and, during use, horizontal, or by further tubular bodies made of COR-TEN steel, or another material with analogous characteristics. - COR-TEN steel, as is known, is a low-alloy steel, for example with 0.2-0.55% by weight of copper, 0.3-1.5% by weight of chromium and 0.1-0.2% by weight of phosphorus. Such steel tends to be self-protected from electrochemical corrosion by means of the formation of a passivating compact surface patina, constituted by oxides of its alloy elements, such to prevent the progressive extension of the corrosion; such film has a varied tonality with the passage of time and usually has brown color.
- Advantageously, the uprights and/or the transverse elements are made of COR-TEN steel, type A, which has a chemical composition as indicated hereinbelow:
C <= 0.12; Mn 0.20 ÷ 0.50; P 0.07 ÷ 0.15; S <= 0.035; Si 0.25 ÷ 0.75; Cu 0.25 ÷ 0.55; Cr 0.30 ÷ 1.25; Ni <= 0.65
in which the % are by weight. - In other situations, the
transverse elements 2 could instead consist of metallic ropes, or other containment bodies such as nets, grates, windbreak panels and still other items. - In the case of
transverse elements 2 constituted by wood beams, or by second metallic sections, these can be constrained to theuprights 3 through a suitable series ofhousing holes 5, or grooves, made on the first metallic sections in a manner such to receive the end or a section of the sametransverse elements 2 for a pre-established length. - More particularly, according to the non-limiting embodiment illustrated in figure, the
uprights 3 delimit afirst hole 5a or a row ofhousing holes 5 that are vertically offset on afirst side 3a, each employed for the insertion and anchorage or the constraining of a first section of a first transverse element or for the insertion and anchorage or the constraining of anend 2a of a first transverse element, and at least onesecond hole 5b on a second side oropposite side 3b for the insertion and anchorage or the constraining of a second section of the first transverse element or for the insertion and anchorage or the constraining of anend 2a of a secondtransverse element 2 situated on the opposite side with respect to a first transverse element with respect to the upright 3. - Advantageously, each
first housing hole 5a on afirst side 3a of an upright will substantially be aligned with asecond housing hole 5b on asecond side 3b of such upright 2, such that each firsttransverse element 2 will be substantially aligned with a secondtransverse element 2 and, more particularly, thefree end 2a of a first transverse element fitted in afirst hole 5a will be facing and directed towards thefree end 2a of a second transverse element fitted in asecond hole 5b aligned with thefirst hole 5a (see in particularfigures 9 and13 ). - Alternatively, each transverse element could be fitted so as to project from both
sides transverse element 2 would be engaged within an upright 3 starting from afirst housing hole 5a so as to pass through the axial opening 5c of the upright 2, traversing asecond housing hole 5b on asecond side 3b of the upright 3 and projecting therefrom. - In substance, the
uprights 3 comprise a tubular body internally defining an axial opening 3c, into which both thefirst housing holes 5a and thesecond housing holes 5b open; theuprights 3 can be used for supporting differenttransverse elements 2 aligned two-by-two at therespective sides axial opening 3c, projecting from bothsides - For such purpose, it is considered that the section of the first metallic sections, i.e. of the
uprights 3, could in this case be greater than or equal to the section of thetransverse elements 2. - The fixing of the
transverse elements 2 to theuprights 3 can be completed by means of suitable locking means, e.g. removable locking, such as screws, bolts or rivets, in particular self-perforating screws, capable of perforating and creating the respective threaded seat, even in steel. - The
uprights 3 can be obtained starting from a sheet of COR-TEN steel which is bent so as to bring opposite borders into flanking, adjacent position, and then the two borders are welded together. Subsequently, two ormore housing holes 5 are formed, e.g. circular, square or polygonal, each set for allowing the insertion and anchorage or the constraining of an end of atransverse element 2. - The
uprights 3 preferably have circular section, but clearly they can also have different section. - Advantageously, the
fence structure 1 can be made with components of different length, in a manner such that they can be better adapted to any need. - According to a further aspect, the present invention provides a
fence structure 1 in which at least one part of theuprights 3 is equipped with illumination means 6, integrated or housed therein. - In the present case, the illumination means 6 can be constituted by a series of lamps or LEDs housed within first metallic sections equipped with at least one slit or groove, which constitutes a portion adapted to allow the outflow of the light or to house the illumination means 6.
- In accordance with requirements, the illumination means 6 can be positioned in the lower part of the
uprights 3, in this case acting like step-lights, as illustrated infigure 4 , or they can be situated substantially at the upper end of theuprights 3 in a manner such to illuminate wider areas. Alternatively, the illumination means 6 could be installed in thetransverse elements 2, in particular if the latter are made of steel. - In the second case, the height of the
uprights 3 which mount the illumination means 6 can be suitably modified. - The use and installation of the fence structure according to the present invention is simple and easy.
- The structure is initially disassembled and its assembly starts with the installation of the
uprights 3, which represent the essential elements for supporting the entire structure and which, due to their particular characteristics, can be laid in various ways. - More in detail, a first mode of installation of the
uprights 3 provides for the obtainment of suitable foundations attained by making holes on the ground, e.g. with mechanical drills, within which thesame uprights 3 are positioned which will subsequently be embedded in the concrete, as illustrated infigure 5 . - A further laying mode instead provides for the fixing of the
uprights 3 on concrete curbs or directly on rocky beds, as illustrated infigure 6 , possibly by employing diamond cutters, e.g. of cup cutter type. - Alternatively, it is possible to fix the
uprights 3 directly on the ground, as illustrated infigure 7 , for example by employing suitable pile-driver machines, which are also advantageously equipped with laser alignment devices. - Once the
uprights 3 are laid, it is possible to complete the structure by also mounting thetransverse elements 2. - If the
transverse elements 2 are constituted by wood beams, or by second metallic sections, these are partially inserted in theholes 5 and subsequently fixed by means of the abovementioned locking means. - The installation is completed by wiring the illumination means 6, if present.
- With detailed reference now to
figures 8 to 14 , afence structure 1 according to the present invention is illustrated, with one or more uprights 3 which, at arespective housing hole 5 of anend 2a or of a section of atransverse element 2 and/or at a saddle-like end or upper head for the abutment of anend 2a or of a section of atransverse element 2, has at least one ear or tab ortongue 3d, made integrally with the upright.Such tab 3d delimits at least one third throughhole 3e. - The ear or
tab 3d, during use or better yet after having inserted a section or anend 2a of atransverse element 2 in ahole 5 or having abutted such end or section on a saddle-like end orupper head 3g, substantially encloses or flanks theend 2a or the engaged or abutted section of suchtransverse element 2. If desired, the tab is aligned with or lies in a plane substantially parallel to the longitudinal extension axis ofsuch end 2a or section of thetransverse element 2 or in any case parallel to the direction of extension of the transverse element between the upright comprising the tab itself and an adjacent upright. - In such case, the locking means comprise at least one screw or bolt or rivet 3f engaged in the third through
hole 3e and in thetransverse element 2, and such screw or bolt or rivet 3f is inserted in a direction, during use, preferably substantially orthogonal to the longitudinal extension axis of thetransverse element 2 or of theend 2a or of the engaged or abutted section thereof. The screw or bolt orrivet 3f is, during use, also substantially orthogonal to the longitudinal extension axis of thetab 3d. According to the embodiment illustrated in the figures, the screw or bolt orrivet 3f is, during use, horizontal or vertical (see alsofigure 15 ). - Advantageously, the third through
hole 3e has central symmetry axis substantially orthogonal to the longitudinal extension axis of thetransverse element 2 or of theend 2a or of the section thereof engaged in therespective housing hole 5 or abutted against a saddle-like end orupper head 3g, and hence, in substance, orthogonal to the longitudinal central symmetry axis of therespective housing hole 5. - More particularly, one or each ear or
tab 3d is projectingly extended starting from a portion of the delimitation edge of arespective housing hole 5 or delimitation edge of a saddle-like end orupper head 3g. - In such case, one or more uprights 3 can have at least one bendable ear or
tab 3d, advantageously movable or bendable, e.g. by means of a tool such as a gripper, between a first position in which thetab 3d is substantially aligned with the edge of the upright (seefig. 10 ) delimiting thehousing hole 5 or the saddle-like end orupper head 3g, and a second constraining position (seefig. 8 ), in which thetab 3d is arranged in tilted position with respect to the first position and orthogonal to the longitudinal extension axis of theupright 3 as well as parallel to the longitudinal extension axis of thetransverse element 2 or to the direction of extension of the transverse element between the upright comprising the tab itself and an adjacent upright. - Additionally, an upright as indicated above forms the object of the present invention even on its own, and hence independently from a
fence structure 1. - With regard instead to
figures 15 and 16 , in detail, these relate to a fence similar to those described above, but provided withuprights 3 also with a saddle-like end orupper head 3g for the abutment of anend 2a or of a section of atransverse element 2. In such case, at least oneupright 3 can, if desired, also be provided with tabs or ears ortongues 3d as indicated above at the saddle-like end orupper head 3g and/or at one ormore housing holes 5. - Moreover, in such case, the
fence 1 could also be provided with belt or "tie"elements 8, each intended to be constrained, if desired by means of snap insertion or by means of screws or the like 9, at its respective ends to opposite sections of a saddle-like end orupper head 3g of anupright 3, so as to fasten and firmly constrain to such upright, a section or an end of one or moretransverse elements 2 abutted against the saddle-like end orupper head 3g. - In order to obtain an
upright 3 according to the present invention, one can bend a flat plate until a tubular component is obtained with free edges side-by-side, and then weld together the free edges of the flat plate; subsequently, one removes material from the upright, e.g. via laser, so as to form the housing hole(s) 5 or the saddle-like end or upper head as well as, if desired the ear(s) or tab(s) 3d if such components are provided. - In order to assemble a fence according to the present invention after having arranged a plurality of
transverse elements 2 and a plurality ofuprights 3, anend 2a of atransverse element 2 is inserted in ahousing hole 5 of an upright or anend 2a of a transverse element is arranged in abutment against a saddle-like end or upper head of an upright or a section oftransverse element 2 is engaged in two alignedhousing holes - If one or more uprights 3 is provided with one or
more tabs 3d, then one bends the ear(s) 3d so as to arrange them so that each substantially encloses or flanks arespective end 2a or lateral section of atransverse element 2 and is aligned with or lies in a plane substantially parallel to the longitudinal extension axis of thetransverse element 2 or to the direction of extension of the transverse element between the upright comprising the tab itself and an adjacent upright. Subsequently, the screw(s) or bolt(s) or rivet(s) 3f is/are engaged in the third throughhole 3e and in a respectivetransverse element 2 so as to constrain the latter to theupright 3. Such solution ensures an easy insertion as well as a correct positioning of the locking means, since the presence of the tab allows arranging the screw, the bolt or the rivet substantially with axis orthogonal to thetransverse element 2 and to thetab 3d (see in particularfig. 12 ), while without the tabs, the screw would have to be engaged starting from a curved section of an upright and hence would be engaged substantially tilted in a transverse element, i.e. with extension axis of a respective stem tilted for an acute angle with respect to the transverse element. - It has in practice been established that the fence structure according to the invention fully accomplishes the pre-established task, since it comes to substitute normal wood fences that over time require considerable maintenance and in any case must be replaced in the long term; simultaneously, such fence structure shows particular aesthetic quality.
- In particular, the fence structure according to the invention has proven to be quite resistant to weathering agents, practically maintenance-free, always ordered with regard to positioning as well as quite simple and quick to install.
- In addition thereto, the fence structure according to the invention has proven to have little impact both on the landscape and on the environment.
- Another advantage of the fence structure according to the invention consists of the fact that if installed along paths that wind through poorly-illuminated areas, it allows solving the problems of poor visibility.
- In practice, the materials used, so long as they are compatible with the specific use, as well as the contingent sizes and shapes, can be of any type in accordance with the requirements and the state of the art.
