Definitions

  • the invention refers to a strong and safe tubular metal railing, of those used for protection, which is characterized by being of a demountable articulated modular structure and satisfying in a simple and easy manner the maximum requirements of functionality for users and installers. It is an articulated railing with a system of prefabricated joints, ball joints and other soleplate fixing and jointing elements, completely novel and characterized by its multiple features: easy installation without welds; adaptable to any plane: vertical, horizontal or inclined; great resistance and stability; easy demounting and replacement; simple maintenance; versatility with regard to the possibilities of combining its elements and incorporating other materials, such as aluminum profiles or wooden handrails, steel cables, or the like; anti-theft security; and outstanding aesthetic quality due to the simplicity and styling of its shapes.
  • This type of railing can advantageously be installed as a protective barrier for people against high falls from terraces, viewpoints, in elevated accesses such as ramps and stairs, as protection for pedestrians in public transit areas open to traffic, or as demarcation and protection for restricted areas, park areas and other pedestrian spaces, which can therefore be integrated in public spaces and grounds as part of the urban furnishings, in developments, buildings and residential complexes.
  • the railing of a demountable articulated modular structure is basically made up of tubular elements, ball joints, connection sleeves, soleplate and wall fixing elements, and other accessories.
  • Tubular elements standard metal pipes, preferably of stainless steel or aluminum, of circular section and widely available on the market, are used in the structure of this railing as handrails and crosspieces in a position parallel to the positioning surface, whether it is horizontal or inclined, and as vertical uprights in a vertical position.
  • the vertical uprights are only composed of a circular-sectioned metal pipe, called the upright pipe, provided with one or several perforations to allow the jointing with other elements.
  • the system provides for different jointing accessories for jointing to the handrails and crosspieces and for soleplate fixing, which are independent, demountable, articulated or not according to the required function with regard to the type of anchoring: embedded or screwed into pavement; on a vertical, horizontal or inclined surface.
  • this system also includes a simple, single-bodied type of upright, called simple upright, incorporating the anchoring plate.
  • the ball joints, articulated and demountable are assemblies of special parts of great robustness and versatility which join the tubular elements together, i.e. handrails and crosspieces to the upright. All the components are independent, easy to assemble on the job site, and they allow for the necessary articulation of the assembly in order to adapt to curves and slopes, being possible to replace all the elements in incidental replacement and maintenance tasks.
  • the jointing of the tubular handrails to the vertical uprights is carried out by means of the assembly of an assembly of parts making up the upper ball joint, which is fixed to the pipes by pressure, without adhesives or welds, valid for any assembly circumstance, horizontal or inclined surface and curved contours, since it is completely articulated.
  • the jointing of the crosspieces or transverse tubular elements to the vertical uprights at any point of the height of the latter is also carried out by means of the assembly of another ball joint or assembly of parts making up the intermediate joint or ball joint.
  • the latter is also fixed to the pipes by means of pressure, without adhesives or welds.
  • the two main types of ball joints also have the common feature that the majority of the assembly is housed inside the pipes by means of pressure, only a minimum part of them outwardly appearing, with the resulting advantages of protection, anti-theft security and aesthetic quality.
  • the two basic types of ball joint mentioned can be combined; i.e. another type of joints can be obtained by means of a mixed ball joint formed by combining or incorporating compatible elements of the upper ball joint and intermediate ball joint.
  • connection sleeves for longitudinally joining pipe spans are housed inside the ends of connected pipes, where they remain hidden, and also have special features object of this invention, since they require neither adhesives nor welds in order to produce strong joints, which are nevertheless demountable.
  • the soleplate fixing bases are assemblies of parts, either independent parts or parts jointed to the upright, which have a different composition according to the desired type of anchoring: fixed or demountable; orthogonal or articulable; on a horizontal, vertical or inclined surface. They also have maximum functionality in terms of other types of requirements, such as allowing maximum versatility of spaces, providing for occasional demounting due to incidental causes, or facilitating the maintenance and replacement of the components.
  • the invention includes the mentioned fixing features, basically summarized in two types of anchors; embedded anchor: the anchoring element is fixed and is completely embedded, hidden and protected inside of the soleplate under the grade level, the uprights and other elements of the railing projecting from the ground being demountable, allowing the reuse of the element embedded in the surface for subsequent assemblies without requiring working or welds; and an articulated foot: the railing is assembled on a soleplate by means of articulated anchoring elements, and is fixed by means of tamperproof screws and protections, such as rivets.
  • the ball joint for distal wall fixing is herein mentioned, a feature of the system allowing the fixing of the ends of the handrail and crosspiece pipes to vertical surfaces by means of an assembly of elements called the ball joint for distal wall fixing which, at the same time, is a sealed finishing for the end of the pipe and a firm anchor to the wall, contributes longitudinal tolerance, since it is extendible, and allows seeking the most suitable fixing point, since it can turn 360° with regard to the axis of the pipe.
  • the general system of the railing of the invention although basically designed as a modular metal structure for tubular elements, provides and allows for the incorporation of other non-metal materials, such as round handrails or crosspieces of solid wood, or opaque or glass partitions, but it also has other special accessories, provided for the fixing of other optional protection elements, such as, for example, steel cables.
  • These accessories are nuts and bolts pieces specific to the invention which allow the fixing of steel cables to the upright pipes on the axial surface of the railing, in combination with and as a complement to systems already existing on the market, allowing to optionally incorporate them, broadening its applications without damage or detriment to its interests.
  • the railing of the invention is adaptable to inclined surfaces, to curved line contours, such as a traffic circle curb and with plan angles comprised between 90° and 270° formed at the meeting point of two railing spans, since the articulated jointing elements allow the incorporation at any position of the tubular handrail and crosspiece elements, whether these are straight or previously formed for the purpose, such as bends and corner finishings existing on the market, or curved and adapted on site.
  • Another feature of the system object of the invention is the fact that it contemplates the behavior of distribution of the loads and forces applied by incidental impacts, such that the railing absorbs the majority of the energy of the impact in the deformation of the elements projecting from the soleplate, without transmitting it to the embedded anchoring elements, thus preserving them from deformation and allowing their reuse.
  • the embedded anchoring elements under the grade level are greatly protected from impacts against the railing, as a result of which it is very difficult for them to deteriorate; they have a pressure fixing device for fixing the uprights, they are reusable without requiring construction, welds or special working, and while the railing is being replaced, they remain hidden and protected under the pavement grade level.
  • the anchoring elements for anchoring to a surface can be fixed or independent and articulated, adaptable to inclined planes.
  • This last anchoring system allows for sufficient mobility for seeking the suitable horizontal and elevated alignment on horizontal or inclined planes. It allows provisionally presenting the railing and when it is well aligned, the soleplate jointing and anchoring elements are definitively fixed.
  • Anti-theft security As means for fixing the surface anchoring elements to the soleplate, hexagonal nuts locked with exclusive steel clamps or rivets preventing the manipulation with common tools are used.
  • the invention has nuts, pins and rivets requiring special tools specific to the invention for the manipulation thereof.
  • the ball joints or joint elements between the handrails and crosspieces to the upright and the locking system of the upright in the anchoring foot at the same time providing solid joints, of great strength, stability and anti-theft security, allow for the demounting of the railing assembly by means of special tools specific to the invention.
  • This provides great convenience in repair.
  • the easiness of demounting and replacing the railings of the invention allows for incidental replacement, repair, cleaning operations, shop treatments, or the like. While one or several elements are being repaired, it is not necessary to lose the use of the railing since the deteriorated elements can be replaced by new ones when they are removed.
  • FIG. 1 Another detail of said railing is that it allows for combinations with aluminum profiles or elements of other materials, such as steel cables conveniently situated on the plane of the axis of the railing, or round solid wood profiles in the handrails and crosspieces or the like.
  • the assembly of the invention is a metal, tubular, articulated and modular railing that can be demounted by means of specialized tools, it is very resistant, preferably of stainless steel or aluminum, versatile and functional, easily adaptable to horizontal, inclined and vertical planes, straight or curved contours, with strong and stable anchors and joints, with anti-theft protection, by means of ball joints and hidden joints assembled by means of pressure, without welds or adhesives, and with a reduced number of components, suitable for incorporating other materials, such as wooden handrails, steel cables or glass partitions, which in spite of its robustness and resistance, has a beautiful styled and simple appearance, which makes it especially indicated for the protection of people in urban spaces, public grounds, developments and public building and home interiors.
  • tubular elements Different systems of modular metal railings based on tubular elements and soleplate jointing and anchoring prefabricated parts can be found among the background of the invention. Even though they integrate tubular elements in handrails and crosspieces, many of these are not systems entirely based on these circular-sectioned tubular elements commonly called pipes, they could therefore be called a mixed system since the uprights are usually of non-tubular metallic materials, such as solid cast iron uprights, or of different prismatic forms elaborated from folded sheet metal, or composite, die-pressed, stamped profiles or the like.
  • the existing systems which can more appropriately be denominated as metal modular tubular systems, based on standard pipes for both the formation of uprights and for the formation of handrails and crosspieces, and soleplate jointing and anchoring prefabricated parts which could be considered as background of the system object of this invention are generally characterized by their limitation, and sometimes impossibility to adapt to the plane on which they are placed, especially if this is an inclined plane, frequently with a variable slope, or with a curved contour, and which in the best of cases solves or tries to solve with systems noticeably different from that of the invention, and an excessive variety of specific components for each case.
  • the pulling force applied by the cable tension adjusters outside of the axial plane causes or favors the rotation and twisting of the upright, tends to deform and weaken the joint and to shift the elements for fixing to the uprights, as well as doing so to the upright itself of the railing the more it is tightened, the fixing elements undergoing multiplied forces as the force is applied at a point distanced from the axis of the upright, producing a lever effect therefore causing instability, impossibility to reach the suitable tension, and it requires the useless application of an excessive pulling force.
  • the systems for fixing cables to railings that are widespread on the market are usually designed to be uprights of a flat section or surface, and when tubular elements are incorporated, it is done by means of fixing elements which are noticeably different from those of the invention, these being complementary to the existing ones, being able to consider them as an amplification and improvement of the already existing and widely known fixing elements.
  • the anchoring plate provided for being screwed into a soleplate is integral to the upright, whether it be welded, glued or screwed in a basic manner, in this last case, the screws, pins or any other fixing system to the upright which are adopted being visible or accessible, with no effective anti-theft protection and, in any case, no system of those which are known incorporates articulated, demountable anchoring plates to be anchored on a surface and combining solidity, strength and anti-theft security.
  • the anchoring systems which can be embedded or housed in the soleplate known until now require masonry work for the demounting thereof in the event of deterioration or replacement of the upright. They do not provide for a solution that minimizes the damage or the damaged element replacement tasks.
  • the embedded anchoring of the uprights is usually used to provide greater solidity to the fixing and to facilitate the adaptation to the irregularities of the surface on which the railing is to be placed during the assembly, but in no case is the anchoring element provided as an independent element of the upright, equally solid and secure, and which also allows for the replacement of the upright without work or complex operations, and furthermore they do not allow for taking advantage of the work and the anchoring elements used in the original assembly, being necessary to start the works from the beginning and to completely replace the pre-existing embedded anchoring elements.
  • railings which are very lightweight and unstable, made up of metal pipes and plastic jointing elements screwed together such that they are adapted according to a specific repertoire of prefabricated parts, some designed as T-shaped clamps and others designed as ends or entrance parts adaptable to the outer curved surface of the upright which are of little resistance and generally used inside commercial establishments and grounds, not as protective railings from falling or against traffic, but rather as guides for the transit of persons or for prohibiting passage.
  • some of the cable end fixing accessories and the anti-theft security means used by the invention for fixing the anchors of the railings on a surface referring to riveted lock screws and nuts, as well as other preceding systems, are comprised in other registrations of the same applicant and inventor, such as E 02380130.1 "REMUVABLE MODULAR URBAN RAILING” dated 18.06.2002; U ES number 200200125, dated 18-01-2002 “SECURITY RIVET” and I ES number 153,187 “RIVETS”, dated 18-01-2002; IN 77300 “URBAN BARRIERS”, dated 21.08.2002.
  • the goal of the invention is to provide a railing of an articulated, demountable and modular tubular or tubular profile metal structure, preferably of stainless steel or aluminum, formed by standard pipes or tubular profiles in the handrails, crosspieces and vertical uprights; strong and demountable, articulated prefabricated joints of different materials called ball joints, which are hidden and pressure-assembled inside the pipes; strong and demountable, hidden, micro-threaded metal sleeves for carrying out longitudinal, pressure connections; prefabricated and independent wall and soleplate fixing metal elements , also preferably of stainless steel or aluminum.
  • the soleplate anchors are of two types: one, embedded, hidden, protected against impact deformation, reusable and pressure-assembled to the upright, and another, for positioning on a surface, hinged and with anti-theft protection.
  • the entire system assembly has a very resistant, strong and stable structure once installed, with anti-theft protection, and nevertheless demountable; it is widely versatile for being very easily adapted to different horizontal, inclined or vertical planes, of straight or curved contour, and also allows for the optional incorporation of other materials, such as solid wood round profiles in the handrails and steel cables by means of specific parts, provided for and developed in the invention; all of the system, as a whole, provides significant advantages regarding cost, ease and quickness of assembly, disassembly, maintenance and replacement.
  • the railing object of the invention is of a simple structure and is basically made up of metal pipes or tubular profiles in the form of handrails, crosspieces and vertical uprights, all of them independent and simply provided with the suitable perforations for allowing the transverse jointing to one another by means of a set of parts called "upper ball joint”, “intermediate ball joint” and “mixed ball joint” which, while solidly fixing them, allows them to take on the desired position to be adjusted to the contour and inclination of the ground or surface on which they are installed.
  • the jointing of the pipe or tubular profile that is the handrail or support on the upper end of the vertical pipe that is the upright is carried out by means of the already mentioned upper ball joint, which is a complex set of parts in turn distributed into two groups of components, a lower pressing action group and an upper expansive action group.
  • the lower pressing action group is housed inside the upright pipe, entering into the upper end thereof, also acting as a cap thereto once assembled.
  • This group of parts is a pressing system having a threaded drive shaft which, by means of a rotational movement, brings together two plates compressing a rubber ring, forcing it to develop a cylindrical volume having a diameter exceeding that of the inside of the pipe, causing a very resistant friction locking
  • the upper expansive action group is housed inside the handrail pipe and is basically made up of three parts, two almost identical semi-cylindrical caps with an also semi-cylindrical internal cavity which, once assembled, form a completely cylindrical housing in which the core, an also cylindrical part provided with a threaded perforation with an axis perpendicular to that of the core, fits.
  • one of the semi-cylindrical caps has a through perforation or channel which, at the time of installation, must be accessible from the perforation made on the pipe or tubular profile of the handrails, and the entire assembly must be positioned such that the threaded perforation of the core, the channel of the semi-cylinder and the perforation of the pipe are aligned, with the aid of a special tool.
  • the drive shaft projecting from the lower compressive action group interlocked in the vertical upright is provided with a threaded end in the shape of a screw, which is introduced through the perforation existing on the pipe of the handrail, and the channel of the semi-cylinder, and is screwed in the core of the upper expansive action group, then causing the pressure interlocking effect of the assembly.
  • an expansive effect of the assembly is produced because the core and the end of the drive shaft are shifted in an opposite directions as it is being screwed, causing the interlocking to occur in the position and orientation in which it is found, therefore thus achieving the strong jointing of the handrail to the upright in the desired position.
  • the transverse joints between crosspieces and uprights are solved by means of the intermediate ball joint, which is a set of components basically made up of two units of a part called a reinforcing block, and another one called a drawbolt.
  • the reinforcing block is a regular prism having through perforations along its two axes of symmetry, each one of them with the features suitable for their function in terms of diameter, length, type of inner surface, smooth or threaded.
  • a screw is housed in one of the perforations, acting as a stud bolt for fixing the reinforcing block in the suitable position inside the pipe, such that the threaded perforation of the latter and that of the pipe are kept aligned at the time of assembly.
  • the drawbolt is a double screw with a thickening in the central portion and threaded in reverse direction on each one of the threaded spans with regard to the other one.
  • the central thickening is provided with a cavity to allow the rotating and tightening action.
  • the operation of the intermediate ball joint consists in that once the reinforcing blocks are introduced and positioned such that all the perforations are aligned, by introducing in them and rotating the drawbolt, the pipes approach one another until reaching the desired tightening pressure.
  • the joints between uprights and handrails can also be solved by means of the mixed ball joint, which combines elements of the upper ball joint with elements of the intermediate ball joint described above.
  • This ball joint is obtained by using the drawbolt and a reinforcing block of the intermediate ball joint.
  • the system provides the possibility of combining the mixed ball joint with another ball joint specific for this function, called the ball joint for distal wall fixing, since the reinforcing block of the mixed ball joint allows screwing down threaded elements in the longitudinal direction.
  • the ball joint for distal wall fixing is an articulated fixing system, basically made up of an assembly of three elements: the so-called sealed end, cylindrically shaped with a half round perimetral channel for housing an o-ring seal, and a perforation in the direction of the cylinder shaft which, in turn, is divided into two spans of different sections; one arm constituted by a folded, L-shaped round rod with spans of different diameters and threaded on both ends, on one end in order to be screwed into the reinforcing block, and on the other end, to be screwed into the third part of the assembly, a disc in turn provided with two perforations, a threaded transverse perforation for screwing one end of the arm, and another axial perforation for allowing the passage of the wall fixing screw.
  • the entire assembly is adjustable and allows longitudinal shifting.
  • connection sleeve The handrail and crosspiece pipe spans are longitudinally connected to one another by means of a tubular sleeve which remains hidden inside the connected pipes.
  • This element called the connection sleeve, is provided with a noticeable, slight central thickening in the shape of an annular rib, and the entire outer surface of near smooth appearance is micro-threaded, such that when the part penetrates the smooth interior of the ends of the pipes to be connected by means of a thrust action together with a slight rotational movement, a stable jointing is achieved as a result of the pressures occurring in the final interlocking once complete penetration of the sleeve is achieved.
  • connection system provided for facilitating the replacement of partially damaged pipe spans without needing to demount the entire span is an assembly of parts called replacement sleeve, incorporating a special interlocking device, similar to the so-called lower pressing action group, which is housed inside the pipe to be connected, combined with an shiftable sleeve, auto-extendable by means of a spring device it is provided with, all of it making up a single and independent assembly.
  • the uprights in this system are pipes provided only with the suitable perforations so as to allow for the fixing of the jointing elements, although there is a type of vertical upright, called simple upright, made up of one upright pipe, with the suitable perforations that are characteristic of the system, and an anchoring plate welded to the lower end which in turn is provided with its respective perforations to allow for soleplate fixing by means of through screws.
  • the anchors or soleplate fixing elements are independent prefabricated assemblies, there basically being two types, according to whether or not they are for embedding in a soleplate or installing on the pavement surface, as described below.
  • the anchor for soleplate embedding is an assembly of parts basically made up of two concentric pipes of a different diameter and length welded to one another at a certain height, leaving between both pipes a passage or separation that is sufficient to allow for the plug-like housing of the lower end of the upright pipe.
  • the strong interlocking of both elements, i.e. of the upright pipe with the embedding foot, is achieved by means of a pressing system similar to the lower pressing action group already described as a component of the upper ball joint.
  • the embedding anchor is housed in the soleplate such that the upper end is at the height of the grade level, so that it is all protected and hidden under the soleplate, but with the opening being accessible from the outside so as to allow for the introduction of the upright.
  • the interlocking system by means of the already known pressing assembly allows for the strong and stable fixing as well as for the demounting and reuse of the foot without carrying out construction or repair work for the latter in the event that it is necessary to replace the upright.
  • the articulated foot is a complex assembly of parts, basically made up of three elements: and anchoring base, a conical-cylindrical arm and a pressing assembly.
  • the anchoring base is a body made up of two volumes, one is in the form of a plate, provided with the suitable perforations so as to allow the passage of the anchoring screws and access to the threaded end of the pressing assembly screw, and the other one is in the form of a spherical cap, in turn provided with a groove allowing the passage of the pressing screw in a sufficiently broad arc so as to allow for different positions of the conical-cylindrical arm to thus form the necessary articulation for facilitating the adaptation to the slope of the plane or ground on which the railing is installed.
  • the conical-cylindrical arm is a hollow body, basically made up of two volumes: one volume, situated at the base or lower portion of the part, is frustroconical, hollow, and has a base with a beveled or countersunk profile, and another, in the upper portion of the part, is a tubular cylindrical volume.
  • the frustroconical portion of the part is that which articulates and is placed on the anchoring base, causing a strong joint in the desired position, and the tubular cylindrical portion is provided for being housed inside the upright and also serving as a support for the pressing assembly characteristic of the system object of the invention and already described above as the lower pressing action group.
  • demountable surface anchors independent of the upright, but not articulable, which are called surface anchoring feet, of which two models are proposed, one for anchoring on a horizontal surface, and the other one, on a vertical surface, called horizontal foot and vertical foot, respectively.
  • Both assemblies basically consist of an arm in the form of a pipe provided for being housed inside the upright pipe, which on one end is a support for the pressing assembly, and on the other end is welded to an anchoring plate, the position of which with regard to the arm varies according to the model, according to the function of the position of the plane on which the railing is installed, horizontal or vertical.
  • the system incorporates other parts of lesser importance but also with their own features, such as the caps for the ends of the tubular handrails and crosspieces of the system, which can be simple or pressure caps.
  • the simple cap is an assembly of two parts, one part being metallic with a basically cylindrical shape which is tightly housed inside the tubular elements of the system and has a thickening at one of the bases so as to act as a stop and outer finish, and the cylindrical part intended for being housed inside the pipes is also provided with a half round groove for housing the other element of the assembly, an o-ring seal, which provides pressure on the assembly, thus causing a strong and airtight finish.
  • the pressure cap is identical to the lower pressing action assembly, the only difference being that the tightening is achieved by means of a conventional Allen screw.
  • the invention provides for carrying out these fixings on the axial plane of the railing, whereupon the fixing parts to be used must be of features adapted to this purpose and are herein described to justify their function, although the system may incorporate other similar parts already existing on the market.
  • the fixing and connection parts for fixing and connecting cable terminals are called threaded stay tackle and double screw.
  • the threaded stay tackle consists of a single-body part made up of two volumes with a common shaft, one corresponding to the threaded-surface cylindrical rod , and the other one corresponding to the smooth-surface head integrated by a symmetrically arranged four-sided mixed prism: two flat surfaced sides parallel to one another, and the other two, curved-convex surfaced sides.
  • the head has a circular, transverse through hole on the flat surfaced lateral sides.
  • the base of the prism corresponding to the head is a flat surface constituted by a four-sided polygon, formed by two straight and mutually parallel lines, cutting two other curved lines, also in a symmetrical position with regard to one another.
  • the double screw consists of a single-body part made up of two cylindrical volumes having a threaded outer surface, both volumes with a common shaft but different diameter and height, one volume acting as a rod and the other one acting as a head, the latter having a hexagonal cavity open from the outer base thereof.
  • the system further uses two prefabricated metal parts called security bolt and rivet.
  • the security rivet is a metal protector constituted by a single semi-spherical body of a circular base or plan and a noticeably flattened outer elevation, generated by the revolution of a continuous curved line without vertices, made up of three arcs of different radii joined at the point of tangency, the part also having an inner open cavity or space at the base, of a cylindrical shape, a slightly vaulted bottom and an entrance, grooved by means of an also cylindrical cavity, of limited height and beveled vertices.
  • the rivet interlocks by pressure on commonly used hexagonal nuts, the solid jointing of both parts occurring due to deformation, it being impossible to separate them without destroying them.
  • the rivet acts as a clinch of the mechanical joint while at the same time hides the nut and prevents operation thereon.
  • the nut and rivet assembly In order for the nut and rivet assembly to provide complete anti-theft security, the nut must be locked prior to the riveting or rivet assembly operation by means of a commonly used security bolt which is introduced in a transverse perforation carried out on the nut for that purpose.
  • the structure of the invention incorporates handrail and crosspiece members integrated by tubular elements, open or in the shape of a very closed C-shaped profile internally having ribs or reinforcement means, and which opening allows access of the pressure components of the ball joints, causing the tensing means to indiscriminately gain access along the entire opening at the points coinciding with the prismatic reinforcing member of said ball joints.
  • the arrangement of open tubular handrails and crosspieces in previous profile shapes constitutes a suitable structure for the formation of screen-protected barriers or railings or with closed, opaque or glass partitions, such that the opening or groove of said profiles allows for the housing of the edges of said partitions which, at the opposite or lower edge, are fixed by means of staples, which are fixed either to a soleplate or to a simple or of this type tubular crosspiece.
  • the modular tubular structure object of the invention is assembled and disassembled by means of operations requiring in some cases specific assembly tools and implements, but since the latter are not object of the claims of the invention, the description thereof is omitted.
  • a preferred embodiment of a barrier shown in assembly examples is proposed, one example is on a horizontal plane ( Figures 1, 2 and 3), and another one is on an inclined plane ( Figures 4 and 5), and two more examples with screened barriers on a horizontal or inclined plane and without a crosspiece ( Figures 58 or 60) or with it ( Figures 61 to 63), wherein the configuration and application of the various elements of the tubular structure according to the idea of the invention can be seen, essentially; the tubular handrail (1), crosspiece (2) and upright (3) elements; the alternative open elements or the profile shaped elements (1a) and (2a); different ball joints (4, 6) of the tubular elements; different fixing elements for fixing to the soleplate (8, 10) and to a wall (11); connection sleeves (12) and other accessories.
  • Said handrail is constituted of a tubular metal handrail (1) and crosspieces (2) of a round section, and two types of uprights, upright pipes (3) and simple uprights (7) ( Figures 12, 13, 14 and 15), the first uprights are provided with the suitable bore holes (18 and 19) for allowing the jointing of the handrail (1) with the upright (3) by means of the upper ball joint (4) ( Figures 6, 7 and 8) or by means of the mixed ball joint (5) ( Figures 28, 29 and 30); and boreholes (20) for jointing the crosspiece with the upright by means of the intermediate ball joint (6) ( Figures 9, 10 and 11), and said railing being constituted of a handrail (1a) and crosspieces (2a) ( Figures 6.1, 6.2 and 9.1) susceptible to being assembled on uprights (3) or (7) by means of the upper ball joint (4), the mixed ball joint (5) or the intermediate ball joint (6).
  • the soleplate fixing of the upright pipes (3) can be carried out by means of the embedded anchoring (8) ( Figures 16, 17 and 18), or by means of screw-down feet screwed on the surface, which in turn can be articulated feet (10) ( Figures 19, 20 and 21), or simple bases (9), ( Figures 22, 23, 24, 25, 26, and 27).
  • the wall fixing of the ends of the handrail is carried out by means of the distal ball joint (11) ( Figures 31, 32 and 33).
  • connection sleeve (12) Figure 34
  • replacement sleeve (12A) Figures 35 and 36
  • the tubular handrail (1) provided with the suitable boreholes (18) or the open handrail (1a) having an opening (1b) and internal reinforcements (1c) and (1d) are jointed to or assembled on ( Figures 6, 6.1, 6.2 and 8) the tubular upright (3), producing a firm jointing between them by means of the upper ball joint (4) ( Figure 7), constituted of three blocks: the upper expansive action group (15) housed inside the handrail pipe (1) (1a), the drive shaft (16) acting as a transmission of the tightening force, and the lower pressing action group (17) housed in the upright pipe (3), the total composition of which, shown in Figure 8, consists of:
  • tubular crosspieces (2) provided with suitable boreholes (19) or open crosspieces (2a), are jointed or assembled ( Figures 9 and 9.1) on the tubular upright (3), also provided with suitable boreholes (20), by means of the intermediate ball joint (6) ( Figure 10), causing a strong jointing, the composition of which, shown in Figure 11, is constituted of:
  • the mixed ball joint (5) is especially useful for reinforcing the fixing to a wall of the end of a pipe in a horizontal position, either the crosspiece (2) or handrail (1), by means of the distal fixing ball joint (11) (Figure 32), producing a strong jointing ( Figure 31), the composition of which, shown in Figure 33 is constituted of the already described parts called reinforcing block (31) and stud bolt (30), the drive shaft (25) and those parts making up the lower group (26), (27), (28) and (29).
  • the most typical upright of the invention is the upright pipe (3) simply constituted of a pipe provided with suitable perforations (20) for allowing the jointing with the crosspiece (2) or fixing of the cable terminals to the wall uprights (7) ( Figures 14 and 15); but there are other upright models, such as the horizontal simple upright (7) ( Figures 12 and 13), made up of an upright pipe (34b) welded to an anchoring plate (34a), also provided with suitable perforations (37) for the fixing thereof to a soleplate, and the simple vertical upright (7) ( Figures 14 and 15) made up of an upright pipe equal to the previous one, but of greater lengths (36, 38), welded to its anchoring plate (39) by means of pins (41), all this arranged and provided with boreholes (40) for the fixing thereof in a vertical position and parallel to the wall by means of screws protected with rivets (14) ( Figure 52), and finished at the lower end with a simple cap (42) ( Figure 38).
  • the horizontal simple upright (7) Figures 12 and 13
  • the fixing (8) embedded in the soleplate and at the same time demountable from upright pipes (3) is solved by means of the anchoring embedded in the soleplate of Figure 16, an assembly of parts (45) ( Figure 17), basically constituted according to Figure 18 of two concentric pipes (46) and (47), of different diameters and lengths, the larger one inserted in the small one and welded together at a certain height, leaving a passage or separation between both that is sufficient for allowing the housing by way of insertion of the lower end of the upright pipe.
  • the pipe (47) is provided with an anchoring element (48) welded on its lower end.
  • a pulling screw (49) constituted of a conventional Allen screw screwed into the lower press (29) and exerting pressure on the upper press (27), causing these two parts to approach one another, compressing the resilient ring (28).
  • the simple connection sleeve (12) of Figure 34 is basically constituted of a pipe (69) provided with a noticeable slight central thickening (71) in the form of an annular rib, and the entire outer surface (70) having a near smooth appearance is micro-threaded.
  • the replacement sleeve (12A) ( Figure 35) incorporates a special interlocking device, similar to the so-called “lower pressing action group”, made up of parts (27), (28), (29) and (49), already described above, combined with the following parts shown in Figure 36:
  • the finishing caps for pipes can be simple or pressure caps.
  • the simple cap (13) (Figure 37) is an assembly according to that described in Figure 38, of two parts, one basically cylindrical metal part (42) housed tightly inside the tubular elements of the system, and having a thickening at one of the bases (42a) in order to act as a stop and outer finishing, and the cylindrical portion intended for being housed inside the pipes is provided with a half round groove (42b) for housing the other element of the assembly, an o-ring (44), providing pressure to the assembly, thus producing a strong and sealed finish.
  • the pressure cap (13A) ( Figure 39) is formed by elements (27), (28) and (29) already described in the "lower pressing action assembly", and by other specific elements shown in Figure 40:
  • the threaded stay tackle (77) consists of a single-body part made up of two volumes with a common shaft, one volume corresponding to the cylindrical rod (80) with a threaded surface, and the other volume corresponding to the head (78) with a smooth surface integrated by a mixed prism of four symmetrically arranged sides: two sides with a flat surface and parallel to one another, and the other two sides with a curved-convex surface.
  • the head has a transverse circular through hole (79) on the lateral sides with a flat surface.
  • the base of the prism corresponding to the head is a flat surface constituted of a four-sided polygon, formed by two straight lines and parallel to one another, cutting two other curved lines also in a symmetrical position with regard to one another.
  • the double screw (81) consists of a single-body part made up of two cylindrical volumes with a threaded outer surface, both volumes with a common shaft but different diameter and height, one volume being the rod (83) and the other one being the head (84), the latter having a hexagonal cavity (82) open from its outer base.
  • Both the stay tackle (77) and double screw (81) are intended for being secured in a corresponding perforation (76) for the anchoring of cables or crosspieces assembled on the uprights (3), (7).
  • the security rivet (14) is a metal protector constituted of a single semi-spherical body of a circular base and outer elevation that is noticeably flattened, generated by the revolution of a continuous curved line without vertices, made up of three arcs of different radii joined at the point of tangency, the part also having an inner cavity (85) open at the base, of a cylindrical shape, a slightly vaulted bottom and an entrance (85) grooved by means of an also cylindrical cavity,, of limited height and beveled vertices (87).
  • the rivet interlocks by means of pressure on commonly used hexagonal nuts (89) producing the jointing of both parts by deformation, being impossible to separate them without destroying them.
  • the rivet (14) acts as a clinch of the mechanical joint while at the same time hiding the nut (89) and preventing operation thereon.
  • the nut In order for the nut (89) and rivet (14) assembly to provide complete anti-theft security, the nut must be locked prior to the riveting or rivet assembly operation by means of a commonly used security bolt (88) which is introduced in a transverse perforation (90) carried out on the nut for that purpose.
