DESCRIPTIVE MEMORY

Object of the invention

Conventional linear flat grids are substantially constituted by the association in equidistant parallelism of a plurality of equal rectilinear metal profiles, which differ in a marginal head area and a flat marginal tail area. The flat marginal area of the tail is provided with regularly spaced circular holes that are transversely crossed by connecting tubes of appropriate diameter so that, by crushing said tubes in the transverse direction thereof and perpendicular to the grid plane, the expansion of The diametral tubes perpendicular to the plane of the grid determines their interlocking in the holes of said profiles and, consequently, the stiffness of the linear grid.

Description of components of the invention

In the various figures of the drawings that accompany this specification, it is found that the rectilinear profiles 1 have, in contrast to a marginal area of head 2, a flat marginal area of tail 3, of such width as that of the previous area marginal head 2, in which there are holes 4 that are crossed by means of linking 5 that admit flexion by themselves, maintaining the parallelism and equidistance between said rectilinear profiles 1.

Figure 1 shows, in its left part, the arrangement of the components of a conventional linear grid in the position prior to its structuring, said components being constituted by rectilinear profiles 1, differentiated in a marginal area of head 2 and a marginal area of tail 3 of width equivalent to that of the previous one, and by means of linking 5 which, in this case, are constituted by connecting tubes 6.

The preceding arrangement of the aforementioned components is explained in the section made in the figure 1 according to line II-II, in which the marginal areas of head 2 and tail 3 are observed and the arrangement in the latter of the holes 4 and the positioning therein of the connecting tubes 6 that pass loosely through said holes 4.

Likewise, in the right part of the aforementioned figure 1, an embodiment of the object of the invention is shown, which consists in diametrically crushing the connecting tubes 6 to form them in a flattened shape P parallel to the plane Q of the marginal head area 2. The connection tubes 6, thanks to their deformation, are diametrically interlocked at diametrically opposite points in the mentioned holes 4, forming connection means 5 of the rectilinear profiles 1. The connection tubes 6 have a smaller moment of force that allows a slight flexion of the same in the sense of being able to approximate or separate the heads of the rectilinear profiles from each other 1. This allows the attachment of the modified linear grid on a concave surface S, as illustrated in the figure 4, or a convex surface, not shown, such as to cover an opening of a cylindrical tubular duct for delivery or return in an ac air installation conditioned.

Figures 5 and 6 illustrate the case in which the linking means 5 of the rectilinear profiles 1 of the linear grid are constituted by steel flares 7 that pass through circular holes 4 provided in the marginal area of tail 3 of said profiles. rectilinear 1. This case includes means of mutual interconnection between the steel ghosts 7 and the rectilinear profiles 1 which are constituted by spacer bushes 8. Figure 6 shows the way in which the linear grid adapts to a concave surface S.

Figures 7, 8 and 9 illustrate the case in which the linking means 5 are constituted by strips 9 that pass through rectangular holes 10 provided in the marginal area of tail 3 of the rectilinear profiles 1 comprising means of related between the strips 9 and profiles.

The preceding strips 9 can be metallic or of plastic material, in both cases endowed with a certain degree of flexibility. The strips 9 have regularly spaced projections 11, provided with a throat 12 transverse to the strap 9, which pass through the rectangular holes 10 provided in the marginal area of tail 3 of the rectilinear profiles 1. The projections 11 fit into a edge 13 of the marginal area of the tail 3 with the respective throat 12 of the projections 11. This case comprises means of mutual relationship between the strips 9 of metallic or plastic material and the rectilinear profiles 1 in question, such as the retention of the strips 9 against the edges 13 of the rectangular holes 10 by means of screws 14. The screws 14 passing through the strips 9 through holes 15, are fixed in the wall of the concave surface S. This does not exclude other means such as welding, glue or others.

Similarly, another possibility of realization of the linking means 5, not represented in the drawings by its evidence in view of everything that has been exposed, resides in that the linking means 5 can be constituted by thick flexible and elastic wires that cross Circular holes provided in the marginal area of the tail 3 of the rectilinear profiles 1. This case comprises means of mutual relationship between the thick wires and the rectilinear profiles 1, which may be one of those provided for the case of the strips 9.

The constitution of the minted linear grilles allows, in one case, to use them as surface coating, whether they are concave or convex, and, in another case, to cover discharge or return openings made in cylindrical tubular air conditioning ducts, as will be detailed later.

As is known, the linear grids 16 are conventionally constituted by the association in parallelism and at equidistant intervals of a plurality of rectilinear profiles 17. The rectilinear profiles 17 which differ in a marginal head area 18 of triangular straight section and a flat marginal zone of tail 19 that emerges from one of the vertices of the previous one. This last flat marginal area of tail 19 is provided with circular holes 20 which, being regularly spaced apart, are transversely crossed by cylindrical connecting tubes 21 of appropriate diameter. This serves so that, in one case, their express expansion determines their interlocking in the circular holes 20 of said rectilinear profiles 17 and, consequently, the stability of the component elements of the linear grid 16 and the rigidity thereof .

Figure 10 shows the single lateral rectilinear profile 17L of a linear grid section 16, which, according to the invention, has on its head 18 an external lateral projection PL. The outer lateral projection PL, comprised in principle in a plane parallel to the plane P of the linear grid, extends, in a magnitude equal to the space of an interval X between these rectilinear profiles 17, forming a depression 22 being of width equal to the of the heads 18 of said rectilinear profiles 17. The outer lateral projection PL is broken at a point 23, orthogonally and parallel to the flat marginal areas of glue 19 of said rectilinear profiles 17, in an angled cantilevered section presenting its two faces 24 equal and of width X equal to that of heads 18 and depression 22 mented. Simultaneously, its edge C remains facing the head 18 of an orthogonally adjacent linear grid.

As illustrated in Figure 11, a first linear grid 16, made in accordance with the invention, has its unique lateral rectilinear profile 17L provided with the outer lateral projection PL. Due to its adjoining on a face of a quadrangular column 25 (preferably square or rectangular) the outer lateral projection PL coincides with its end face of the angled cantilever section with the plane P of a second linear grid 16 and is at a distance D of the conventional rectilinear profile located in lateral position and lacking the external lateral projection PL. In view of Figure 11, it is noted that the corner E of the coating has an acceptable visual continuity, since the outer lateral projection PL of the lateral rectilinear profile 17L configures the corner hiding the discontinuity that would occur in the case of not existing such outer lateral projection PL.

In Figure 12, it can be seen that the adjacent faces of a column 25 are covered by two sections of linear grid 16 that laterally do not reach the corners of column 25 leaving a convex dihedral uncoated. In this dihedral a single-piece dihedral cantonera 26 is installed, which has at least one of the rectilinear profiles 17 on each of its two faces and a bisector profile 27, projected from the apex of the single-piece dihedral cantonera, finished off in a straight angular profile 28 The faces of the straight angular profile 28 are coplanar with the planes of the grid sections 16 linearB located on the faces of the column 25.

On the other hand, it is found that the connecting tubes 21 of the case of the previous figure have been replaced by connecting tubes 21A that have been subjected to a flattening. This flattening allows a certain flexibility to the linear grid, which makes it suitable to be installed on slightly curved surfaces and facilitates its installation in the columns 25 by means of through holes for screws 29 that are secured in plugs 30 inserted in holes of the column 25 .

Another aspect of the architectural cladding of the invention is shown in Figures 13 to 22. This is done with a pavement that matches the wall and column cladding described above. Said pavement is constituted by the association in juxtaposition of a plurality of pieces presented in the form of tables and / or plates of solid metallic material. Pieces 31A or 31B are related respectively to other equal pieces 31A or 31B by fitting at least one side of each of said pieces, with one of the sides of another similar piece. For this purpose the pieces have sides properly shaped to carry out the fitting of them by tongue and groove.

As shown in the front elevation view of the end of a piece 31A in the form of a board, which can have dimensions of about two meters long and about twenty-five centimeters wide, such as that shown in Figure 13.

This referred piece 31A is intended for association in juxtaposition with a pair of pieces 31A or with a plurality of pieces 31B which, respectively presented in the form of tables or plates of solid metallic material, are parts 31A or 31B related to other parts 31A or 31B equal by fitting at least one side of each of said pieces with one of the sides of another similar piece. For this purpose, the minty pieces have suitably shaped sides to carry out their fitting by tongue and groove.

As shown in Figure 13, parts 31A are configured as tables. The pieces 31A, with the exception of two marginal lateral zones left 32 and right 33 according to the drawings, have a substantially flat surface 34, while their unseen surface 35 is longitudinally grooved by rectangular flattened rectangular bands 36, alternated with flattened recesses 37 juxtaposed between consecutive arrangements of said rectangular bands in flattened relief 36, both being of similar width. Simultaneously the pieces 31A have tongue and groove means of the slot and tongue type. In one of the left side marginal areas 32, the pieces 31A have, in the part of the unseen face 35, a narrow rectangular band in relief 38 located between the corresponding marginal recess 37A and a minor marginal recess 39 limited by a tongue of junction 40 that forms a descending step 41 that constitutes one of the two longitudinal edges of the piece. On the other hand, in the other of the right marginal areas 33, the piece 31A has a narrow rectangular embossed band 42 which, arranged in juxtaposition to the corresponding recess 37A, is extended in a wide cantilever flange 43 and in this other edge of the piece forms a groove 44 limited between said wide cantilever flange 43 and a short tongue 45, also in cantilever.

Figure 13 illustrates the case in which, according to a preferred solution of the invention, the face 34 of the pieces 31A has its surface unidirectionally grooved by thin grooves 46 of angled section. The grooves 46 being parallel to one of the sides of the piece 31A and equidistant from each other, present as a characteristic of the invention, as illustrated in Figures 18 and 19, a mutual distance equal to that of the head of the slats 47 and the openings 48 of a linear grill 49, of those used as an air conditioning outlet, which has been installed as a wall covering.

Figures 14 to 17 show the form of tongue and groove coupling by juxtaposition of two pieces 31A in the form of a table, although they also serve to show the coupling between two pieces 31B in the form of a plate, such as that of Figure 20.

A portion of the right marginal lateral area 33 of a piece 31A seated on the floor 50, specifically the right marginal zone 33 in which the groove 44 of the tongue and groove means appears is illustrated in Figure 14.

Figure 15 shows the arrangement of the same portion of part 31A of Figure 14, once fixed by a screw 51 on the floor 50.

Figure 16 shows the portion of a first piece 31A, like that of the previous figure, and a portion of the left marginal lateral zone 32 complementary to the right marginal lateral zone 33 of a second piece 31A to juxtapose the first piece 31A to which the said portion belongs.

In Figure 17 the final coupling of the two portions of the pieces 31A is checked.

As shown in Figures 20, 21 and 22, the pieces 31B configured as plates have the same tongue and groove means as the pieces 31A configured as tables, however, the pieces 31A in the form of a table have complementary tongue and groove means only two of its opposite sides, while the plate-shaped pieces 31B have complementary tongue and groove means on all pairs of opposite sides.

In the wide splice tongue 40, provided in one of the edges, the pieces 31A and 31B have collision holes 51A for the passage of screws 51 for fixing the piece 31A or 31B to the floor 50. The screw heads 51 they are hidden under the minor marginal recess 39 of the left side marginal zone 32 opposite the piece to be assembled.

The pieces 31A in the form of boards may have the surface of their face seen 34 grooved, or not, by the fine grooves 46. Preferably the grooves 46 are arranged longitudinally, without excluding that they can also run transversely, and even in the two senses to form a grid. The same applies to the case of pieces 31B, which, in addition, can have any polygonal geometric shape.

Figure 23 shows a cylindrical tubular conduit 52 of an air conditioning or ventilation installation in which a linear grid 53 is installed, which is arranged transversely, is contained within a perimeter frame 54, through which it results Apparent and fulfills its functions of impeller of the air conditioning. It is noteworthy that said perimeter frame 54 is constituted by orthogonal straight section profiles, whose sides are adapted to the curvature of the area of the cylindrical tubular conduit 52 on which the perimeter frame 54 is installed. In the case of a rectangular configuration , the perimeter frame 54 has two of its arcuate sides 55, arranged in opposites in an equally arcuate manner according to the diameter of the cylindrical tubular conduit 50, and the other two sides, rectilinear 56. Also, these rectilinear sides 56, which as shown in figures 27, 28 and 29, they have an outer wing 56A and an inner wing 56B, and the arcuate sides 55, which have an outer wing 55A and an inner wing 55B, constitute the outer wing 55A and 56A of the section straight of a settling means for the attachment of the grid 53 linear to the surface of the marginal area of the window 57 practiced in the cylindrical tubular conduit 52.

Figure 24 shows, according to the section indicated in the previous figure, the cylindrical tubular conduit 52 in which the window 57 has been opened for the insertion of the assembly formed by the said arcuate linear grid 53 and a regulator module 58, whose function and constitution will be detailed below.

Figure 25 illustrates the arcuate linear grid 53, which is constituted by the association in equidistant parallelism of rectilinear profiles 59 that adopt an arcuate transverse arrangement, established by connecting tubes 60, according to an arc suitable for the diameter of the conduit 52 tubular cylindrical and comprised in the opening of a perimeter frame 54, as shown in the section that of this figure 23 constitutes figure 27. The figure shows that the perimeter frame 54 is provided with settlement means outside the cylindrical tubular conduit 52, formed by wings 55A and 56A, while the arrangement of anchoring means 61 is shown inside the cylindrical tubular conduction 52, all in correlation with the window 57 practiced therein.

In figures 25, 26, 28, 29 and 30 it is shown that the regulator module 58 of the flow rate of the air conditioner is constituted by a substantially parallelepiped body 62 which, lacking the large walls, is arranged on the back of the perimeter frame 54 of the arcuate linear grid 53, so that the edges of its medium walls 62A fit, by means of a grooved seat provided on the free edge of said median wall 62A facing the said perimeter frame 54, with the edge of the inner wing 56B of the rectilinear sides 56 of the mentioned perimeter frame 54.

As shown especially in Figure 30, the rectilinear sides 56 of the perimeter frame 54 serve as the basis for coupling the air flow regulator module 58, which is a carrier of a plurality of shutter slats 63 that regulate the passage of air by its positioned controlled at will.

As shown in Figure 31, the profiles that make up the arcuate sides 55 have a plurality of transverse recesses 64 in their inner wing 55 which, being equal and equidistant, allow the bending of the outer wing 55A of the profile of the arcuate side 55 in the how it is seen in figure 32.

The number of transverse recesses 64 corresponds roughly to the number of rectilinear profiles 59 provided in their association to form the arcuate linear grid 53 and in each of them substantially one of the ends of said rectilinear profiles 59.

In figures 24, 28, 29 and 30 it is found that the two arcuate sides 55 of the perimeter frame 54 mount in its inner wing 55B a partition 65 in the form of a circular segment that supports the anchoring means 61 of said perimeter frame 54 to the cylindrical tubular conduction 52. The anchoring means 61 are in correspondence with a wide recess 66 which, provided on the minor walls 62B of the regulator module 58, is centered on the minor walls 62B for the passage of an element of said anchoring means 61.

In Fig. 29 it can be seen that the rectilinear sides 56 of the perimeter frame 54 have on the outer face of their inner wing 56B a ribbed longitudinal rib 67 which, together with an equally longitudinal edge 68 determined on the outer face of the grooved seat of the medium walls 62A of the regulator module 58, constitute the anchor points for the ends of some elastic clamping arches 69 with which the perimeter frame 54 and the regulator module 58 are coupled together.

In figures 24, 28, 29 and 30 it is shown that the anchoring means 61 of the assembly formed by the perimeter frame 54 and the regulator module 58 inside the cylindrical tubular conduit 52, are mounted on the partitions 65 in the form of circular segment of the perimeter frame 54 in correspondence with the wide recesses 66 made in the minor walls 62B of the regulator module 58. In addition, the anchoring means 61 are constituted by an anchoring bolt 70, in the form of a broken "S" in sections. rectilinear, which at one of its ends is requested by a compression spring 71 and related to a threaded spindle 72 to the anchor bolt 70, determining the rotation of the threaded spindle 72 the advance or recoil of the anchor latch 70, which applies its other end on a block 73 seated against the inner margin of the window 57 made in the cylindrical tubular conduit 52.

In cases where linear grids 74 are intended to constitute a wall covering, dorsal suspension means are provided. As illustrated in Figure 33, the dorsal suspension means are constituted by vertical supports 75 which are formed by grooved metal profiles. The profiles differ on a flat bottom 76, with which they are attached to the wall, and on two sides 77, which regularly have recesses 78 coupled, in one case, those of one side with those of the opposite side and, in another case, arranged on only one side. The recesses 78 act as suspension means by its lower section 79 and as retention means by its tongue 80.

These vertical supports 75, preferably, will have a length equal to that of the linear grids 74 to be supported, as shown in Figure 34, without excluding other possibilities, such as those that apply to the case of the linear grilles 74 covering the ceilings , whose characteristics are described below.

The linear grids 74 intended to cover a roof or the like are fixed thereto by means of horizontal supports 81 formed, as illustrated in Figure 35, by short corrugated metal parts. The metal parts differ in a flat bottom 82 and two sides 83 which have on each side, in one case, two recesses 84 coupled, in one case, those of one side with those of the opposite side and, in another case, arranged on only one of the two sides. The recesses 84 act as suspension means and as retention means by means of a hook configuration 85.

Each of these horizontal support pieces 81, in the case of having four recesses 84, serves to support four corners of as many linear grids 74, as shown in Figure 36, having provided that, in the case of holding the Linear grilles 74 next to the wall, the horizontal supports have recesses 84 on only one of their sides.

The linear grids 74, as illustrated in Figure 37, can be configured at the time of installation according to the geometry of the space available at the place of its positioning, for which, in the case of bias configurations, it is it is essential to have intermediate tubes 86 that retain the new ends of the longitudinal profiles 87.

5 Likewise, the linear grids 74, as shown in Figure 38, can be chamfered at their ends 88 in cases where two linear grids 74 meet to form a convex corner, without excluding a concave corner, which can be solved from two ways, as noted in the aforementioned figure 38.

As illustrated in Figures 39 and 40, in the case of a pavement, it is envisaged that the pieces 31A in the form of boards, have in identical position slots 89 in the extreme edges that lack means of

10 tongue and groove. In their facing position, the grooves 89 serve as the middle fitting of lenticular pieces 90 of mutual relationship, as shown in Figure 41.

 2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The claimed priorities are considered valid and correspond to claims in the present patent as follows: Priority ES1069272U: claims No. 1-7 Priority ES1069273U: claims 8-13 Priority ES1070730U: claims No. 14-22 Priority ES 1070246U: claims No. 23 -32. The reiv. 23 depends on the reiv. one The patent under study describes an architectural cladding for 3 different areas: - Coating for walls, columns and ceilings: corresponds to claims 1-13 - Coating applied to a grid located on said walls, columns and ceilings: corresponds to the reiv. 23-32. The reiv. 23 depends on reiv. 1 - Floor covering: corresponds to claims 14-22. CLAIM 1. Claim 1 is a very general claim that describes an architectural cladding intended to cover the interior surfaces of a building, such as walls, columns and roof, adapting to flat, curved, broken or stepped surfaces. Said cladding is formed by groups of parallel and equidistant metal profiles, provided by practicable means of fixing between them and to the corresponding surface of the building. Said claim does not describe the shape of the metal profiles or the fixing means. The closest document of the state of the art is document D01 which, like claim 1 of the patent under study, describes a building material for walls, floors, etc., which consists of parallel and equidistant elements that, due to to its configuration it can adapt to different types of surface like the patent under study, and that is provided with means of fixation to each other by means of metallic elements. The invention defined in claim 1 does not differ from the known technique described in document 1 in any essential way. Therefore the invention as claimed in claim 1 is not considered to involve inventive activity. CLAIM 2: Claim 2 describes the architectural cladding formed by flat grid frames without frames that are composed of a plurality of parallel and equidistant rectilinear profiles. Said profiles differ in a head and tail area provided with regularly spaced circular holes that are transversely traversed by connecting tubes (linking means) which determines the interlocking of said connecting tubes in the holes of said profiles and which admit the flexion by themselves, maintaining the parallelism and the equidistance between the mentioned profiles. Document D03 (see Figure 1-3) describes a grid of identical characteristics and design. However, the grid of document D03 is intended for the air outlet of a ventilation circuit and not for an architectural coating. Another important difference is that the joining tube of document D03 does not allow bending. The fact of allowing flexion makes said grid suitable for use as a coating that can be adapted to different types of surfaces. Thus, the claimed invention implies an improved effect compared to the state of the art. Furthermore, it is not considered obvious that one skilled in the art obtains the invention from the documents mentioned above. State of the Art Report Page 4/6  WRITTEN OPINION Application number: 201190036 CLAIMS 3-7: Claims 3-7 describe different types of linking means. Claims 3-7 are dependent on claim 2 and as they also meet the requirements of the PCT with Regarding novelty and inventive activity. CLAIM 8: Claim 8 describes an architectural cladding formed by grilles as described in claim 1 but incorporating a variant in one of the end profiles to serve as a finish in corner encounters (for example in the pillars). Taking into account the argument with respect to claim 2, the invention according to claim 8 meets the requirement of inventive activity. CLAIMS 9-13: Claims 9-13 are dependent on claim 8 and as they also meet the requirements of the PCT with respect to novelty and inventive activity. CLAIMS 14: Claim 14 describes a type of architectural cladding constituted by the association in juxtaposition of a plurality of pieces that, presented in the form of tables and / or solid metal material, whose sides have sides properly shaped to carry out the fitting of said sides by tongue and groove. The closest document of the state of the art is document D02, whose publication date is 01/22/2009 prior to the date of presentation of the priority claimed by the applicant and corresponding with the object of invention of claim 14: ES1070730U with presentation date 06/16/2009. The invention defined in claim 14 does not differ from the known technique described in document D02 in any essential way. Therefore, the invention according to claim 14 is considered obvious to one skilled in the art. Accordingly, the invention according to claim 14 is not considered to involve inventive activity. CLAIMS 15-16: Claims 15-16 are dependent on claim 14 and describe different tongue and groove options. These tongue and groove options are simply one of several obvious possibilities that an expert in the field would select according to the circumstances, without the exercise of inventive activity, to solve the problem posed. CLAIM 17: Claim 17 depends on claim 15 and describes the choice of aluminum as the material for the longitudinal pieces that make up the floor covering. Such choice is simply one of several obvious possibilities that an expert in the field would select according to the circumstances, without the exercise of inventive activity, to solve the problem. CLAIM 18: Claim 18 describes the longitudinal pieces that make up the floor covering characterized by presenting its unidirectionally grooved surface by thin angular grooves equidistant from each other with a distance equal to that presented by the head of the slats and the gaps defined in the claims. 2. These characteristics are characteristics with an aesthetic function and lack inventive activity. State of the Art Report Page 5/6  WRITTEN OPINION Application number: 201190036 CLAIMS 19-22: Claims 19-22 describe the lower surface (the unseen surface) of the longitudinal pieces characterized by longitudinally presenting rectangular flattened embossed rectangular bands with flattened recesses. The way of splicing between said longitudinal pieces and also between the pieces configured as plates are also described. It also describes the option of hidden screws for fixing the piece to the ground in the area of the joints. In claim 19, the slight constructive variant of the splice with respect to document D02 is considered within the scope of the usual practice followed by the person skilled in the art, especially since the advantages achieved are readily anticipated. Consequently, the object of claims 19-22 also lacks inventive activity. CLAIMS 23-32: Claims 23-32 describe the application of the coating defined in claim 1 for use in a delivery and return grid in the circular section tubular ducts of an air conditioning or ventilation installation. Claim 23 describes a linear grid composed of a plurality of parallel and equidistant rectilinear profiles. These profiles differ in a head and tail area equipped with regularly spaced circular holes that are transversely traversed by linking means that allow flexion by themselves, maintaining the parallelism and equidistance between the aforementioned profiles. Document D03 (see Figure 1-3) describes a grid of identical characteristics and design. However, the main difference is that the connection tube of document D03 does not allow bending. The fact of allowing flexion makes said grid suitable for adapting to tubular ducts of circular section. Thus, the claimed invention implies an improved effect compared to the state of the art. Furthermore, it is not considered obvious that one skilled in the art obtains the invention from the documents mentioned above. CLAIMS 24-32: Claims 24-32 are dependent on claim 23 and as they also meet the requirements of the PCT with respect to novelty and inventive activity. State of the Art Report Page 6/6
