DETAILED DESCRIPTION

  Figures 1 and 2 show schematically an exemplary embodiment of a grid according to the invention.

  The grid thus mainly comprises three basic elements: at least one cross member 1 and at least one bar 2 connected to each other by at least one connecting element 3. For this purpose, the cross member 1 comprises at least one passage 11 intended to receive a part of the connecting element 3 connected to a bar 2.

  Typically, each crossbar 1 is laid horizontally, each bar 2 is laid perpendicularly, vertically. Of course, variants are possible. For example, each cross member 1 and / or each bar 2 can be inclined.

  The crossbar 1 is fixed firmly at its ends 12 to a bay frame or fence, by any appropriate means. It may for example be a recess in the material forming the frame of the bay, possibly by masonry, or without recess on a mounting plate, or by a weld in the frame of the fence for example. It is thus understood that the crossbar can be fixed horizontally, vertically or obliquely depending on the case. A user cuts the crossbar 1, manufactured in a standard way, to the desired length by means of a saw.

  The cross member 1, preferably rectilinear or curved, may be of any section. It can thus be for example circular, ovoid, square, or L-shaped, U, H, angle, etc. It is preferably of rectangular cross section. The cross section of the cross member 1 may be solid or hollow.

  Each connecting element 3 comprises on one hand at one of its ends a rod 31 adapted to be introduced into a passage 11 of the at least one crosspiece 1 and an enlargement 32 of section capable of coming into longitudinal abutment on the crosspiece 1 a Once the rod 31 introduced into the passage 11. The enlargement 32 is for example an annular bead, for example torus type. Each element 3 comprises, at its end opposite the rod 31, with respect to the widening 32, means 33 capable of cooperating with a bar 2.

  The section of each passage 11 thus substantially corresponds to the outer contour of the rod 31 of the element 3. The cross section of each passage may be of any shape, for example square, rectangular, circular or ovoid. It is preferably of non-revolution cross section, in order to avoid the rotation of the rod 31 in the passage 11 of the crossbar 1. It can thus be for example of L-shaped cross section, U, H angle etc. It is for example circular truncated on two portions opposite one another. Thus, the cross section of each passage 11 and the outer contour of each rod 31 comprise two portions forming an arc 23 opposite to each other. They also comprise two rectilinear portions 24 parallel and opposite one another and connecting the circular arcs 23. Thus, this particular contour, having two planes of perpendicular symmetries, allows a user to have two possible aspects. during the custom installation of its grid. If the rectilinear portions 24 are placed parallel to the greater length of the crossbar 1, the rod 31 will mainly have a rectangular flat visual appearance. If instead, the rectilinear portions 24 are placed perpendicularly to the greater length of the crossbar 1, the rod 31 will have a mainly rounded cylindrical visual appearance. The user therefore chooses the appearance of the rod 31 he desires according to the orientation of the passages 11 and the different sections 23 and 24 on the crossbar 1.

  In addition, the passages 11 are preferably spaced regularly, and the number of passages 11 corresponds to the number of bars 2 that the user wants to fix, in front of his bay for example. The spacing between two passages is preferably in accordance with the standards in force, for example 11 cm maximum.

  As shown in FIGS. 3 to 7, the cooperation means 33 between the element 3 and a bar 2 provided on the element 3 mainly comprise either a bore 36 complementary to the outer contour of a bar 2, solid or hollow, or a shaft 40 complementary to the inner contour of a hollow bar 2.

  Indeed, each bar 2 can be either full as shown in Figures 1 and 10 for example, or hollow as shown in Figure 13. The cross section of each bar 2 can be any. It should be noted that the term bar must be understood in the broad sense of the term. The section of the bar 2 can have all possible proportions and the bar 2 can have all the lengths. Thus, the cross section can be square, rectangular or circular. It is preferably of non-revolution cross section, in order to avoid the rotation of the bars 2 in the means 33. It can thus be of L-shaped section, U, H, angle, ovoid, etc., for example. For example, it is circular truncated like the rod 31. Thus, the cross section of each bar 2 comprises two portions forming an arc 23 opposite to each other, and also comprises two straight portions 24 parallel and opposed, one with respect to the other connecting the circular arcs 23. Thus, this particular contour, comprising two perpendicular planes of symmetry, allows a user to have a visual appearance is rectangular or cylindrical for the bars 2 during the custom-made installation of its grid.

  According to a variant shown in FIG. 17, the grid may furthermore comprise plates 6 forming hidden cover panels or decorative shutters in filling, the plates being placed between two bars 2. The plates 6 are for example rectangular, but may comprise also a bent side 62 as shown in Figure 17.

  Each plate 6 is inserted between two longitudinal grooves 25 each made on a bar 2, as shown in FIG. 18. In the example of FIG. 18, the grooves 25 are formed in the rectilinear sides 24, but they can of course be practiced in the arcuate sides 23.

  The connecting elements 3 may also include grooves so that the plates 6 can be inserted between the bars 2 until the sleepers 1.

  The plates 6 may be solid or be perforated. In the latter case, they then comprise decorative motifs 61 pierced in the plates 6.

  In addition, the bar 2, which is preferably rectilinear, can also be bent, twisted, curved, decorated, etc. It is recalled that during the installation of the grid by a user, it cuts to the right length each cross 1 with a saw. The grid advantageously comprises two crosspieces 1. It then cuts to the right length the bars 2, also made in a standard way, with a saw. He then associates the bars 2 to the ties 1 through the connecting elements 3. He then fixes the grid to measure in the frame of a bay or a fence by any appropriate means.

  Several nonlimiting examples of connecting elements 3 are shown in longitudinal section in FIGS. 3 to 7, as well as in FIGS. 20 to 23.

  Thus, in FIGS. 3 to 7, the principal means of each element 3 are repeated. In these figures, as well as in all of the figures, similar elements bear the same numerical references.

  Thus, Figures 3 to 7 show that the rod 31 - which is recalled that the cross section may be any, but in any case corresponds to the cross section of the passages 11 over at least a portion of its length has a distal free end 34. The distal end 34 may have any longitudinal profile. It can be cut at a right angle as in FIG. 3, or in the form of a point as shown for example in FIGS. 4 and 5. FIGS. 6 and 7 show that the free end 34 of the rod 31 can comprise means 38 and 39 cooperating with a distal decorative element 4, a non-limiting example of which is visible in FIG. 8.

  The element 4 thus has a longitudinal profile 43 of any decorative type, for example of rounded or pointed shape, and having at its base an enlargement of section 45, for example in the form of a bead. It comprises a bore 42 which cooperates with the outer contour of the rod 31. A shoulder 44 reduces the cross section of the bore 42 to give a narrower bore 41 which cooperates with the outer contour of a centering finger 38. finger 38 corresponds in fact to the reduction, thanks to a shoulder 39, of the cross section of the rod 31. The cooperation between the finger 38 and the bore 41 can be done by a force, gluing, welding or a thread / groove connection.

  The depth of the bore 41 is preferably greater than the longitudinal extension of the finger 38. Thus, the shoulders 39 and 44 cooperate so that the element 4 comes into abutment longitudinally on the element 3 when the grid not comprise a decorative part 5 described later and visible in Figures 9, 10 and 19. The shoulders 39 and 44 do not cooperate when the grid has such a decorative part 5. In addition, any cutting defects on the free end the finger 38 are not visible and do not interfere with the cooperation of the element 3 and the element 4. FIG. 16 schematically represents an embodiment of a grid according to the invention in an assembled position having distal decorative elements according to Figure 8.

  FIGS. 3 to 7 show that, preferably, the rod 31 has on its outer contour means 35 capable of ensuring a force fit of the rod 31 in each passage 11 of the cross member 1. The means 35 are preferably located at the base of the rod 31, adjacent to the widening 32.

  For example, the means 35 may be in the form of protuberances or ridges extending longitudinally with respect to the rod, as shown in particular in Figure 15. The length of the grooves 35 is preferably less than the thickness of the cross member , so that they are not visible after the insertion of the rod 31 in a passage 11. These grooves 35 crash during the mounting of the rod 31 in the passages 11 and thus prevent it can be easily removed the rod 31 of the passages 11. This is a frictional locking.

  The ridges 35 may also extend transversely relative to the axis of the rod 31. They have for example a triangular profile and cooperate with a recess on the inner wall of a passage 11 for example for a mechanical locking face / face . It is of course possible, in the absence of such streaks, for example to stick the rods 31 in the passages 11.

  The widening 32 is preferably made of material on the rod 31 or is an element added on the rod 31. The widening extends perpendicularly with respect to said rod 31. The longitudinal section of the widening 32 can be any, and varied aesthetics.

  It is recalled that each element 3 comprises at the end opposite the rod 31, relative to the widening 32, means 33 adapted to cooperate with a bar 2.

  Figures 3 and 6 show that the means 33 may comprise for example a tube 33 in which is formed a bore 36 complementary to the outer contour of a bar 2 full or hollow. Figure 5 shows a variant according to which the means 33 do not comprise a tube. The bore 36 is thus made directly from the widening 32 in the interior of the rod 31.

  In the cases of FIGS. 3 and 6, the possible defects in cutting the ends of the bars 2 are hidden by the bore 36. FIG. 14 shows in particular the bore 36 of the element 3 adapted to receive a bar 2. It can be seen that the inner contour of the bore 36 corresponds to the outer contour of the bar 2.

  Figures 4 and 7 show that the means 33 may comprise mainly a shaft 40 complementary to the inner contour of a hollow bar 2. Figures 4 and 7 also show that the element 3 comprises, preferably, at the level of the enlargement 32 , a groove 37 on the peripheral periphery of the base of the barrel 40. The groove 37 is able to receive one end of a hollow bar 2 fitted on the barrel 40, so as to hide any defects in cutting the ends of the bar 2 .

  Figures 20 to 23 show further examples of possible embodiments of the connecting element 3.

  FIG. 20 thus shows that the element 3 comprises on the one hand an elongate body, for example cylindrical and threaded or decorated, embodying both the rod 31 and the cooperation means 33, which can also be threaded. Thus the rod 31 may or may not cooperate with a decorative element 4, and the means 33 with a hollow bar. The element 3 comprises on the other hand a widening 32 in the form of a washer fixed on the elongated body by any appropriate means, for example crimping or gluing. The puck can be decorated in different ways.

  FIG. 21 shows that the rod 31 and the means 33 are materialized by an elongate shouldered body and passing through a washer that embodies the enlargement 32. The rod 31 is located on the side of the body of smaller diameter. In the case of Figure 21, the washer is preferably hollowed out circularly, so that the shoulder of the elongated body is covered by a portion of the washer 32. The cooperation means 33 cooperate with a hollow bar or full.

  Figure 22 shows that the rod 31 is materialized by a wick, which can be threaded, and which is engaged with a tapping or a bore of a tube 32 which embodies both the enlargement 32 and the cooperation means 33 .

  FIG. 23 shows that the rod is a flared-head wick passing through a tube 33 for cooperation and enlargement 32. The wick passes through a wall through a bore in the tube at the level of the enlargement 32, the flared head of the wick being in the tube.

  Figures 9, 10 and 19 show that it is possible to add to the grid at least one decorative part.

  Each decorative piece 5 mainly comprises a plate 53 having a passage 51 complementary to the rod 31 of the connecting element 3. Preferably, the passage 51 is of the same section as the passage 11. The part 5 is interposed between the crossbar 1 and an enlargement of an immobilizing part. As shown in FIG. 19, the immobilizing piece can be the decorative element 4, and in this case the widening is for example the bead 45. As shown in FIGS. 9 and 10, the immobilization piece can also be be the connecting piece 3, and in this case the enlargement used for blocking is the widening 32 of said connecting element 3.

  It is understood that each piece 5 is locked between the element 3 or 4 and the crosspiece 1, in particular thanks to the ridges 35 of the element 3. The part 5 also comprises decorative shapes 52 integrally formed on the plate 53. decorative are for example volutes as shown in Figures 9 and 10, or more linear forms as shown in Figure 12.

  In all cases, the connecting element 3 may consist of a single piece, may be monobloc or made of several pre-assembled parts and / or assemble by the user. The various joining techniques may for example be gluing, screwing, crimping or welding.

  FIG. 11 thus shows an alternative embodiment according to which an element 3 already comprises a decorative part 5. It is understood that all the shapes of the element 3 represented for example in FIGS. 3 to 7 may comprise such a decorative part 5 assembled .

  Figures 24A to 29 show another possible embodiment of the invention.

  In these figures, as in all the figures of the present description, similar elements bear identical reference numerals.

  FIGS. 24A and 24B show that the connecting element 3 comprises, as in the embodiments already described, at one of its ends a rod 31 adapted to be introduced into a passage 11 of the at least one visible crossbar 1 for example in FIG. 29. The rod 31 ends preferentially with a shoulder 39.

  The element 3 also comprises a widening 32 of section capable of coming into longitudinal abutment on the crossbar 1 once the rod 31 inserted into the passage 11. The widening 32 is for example an annular bead, for example torus type.

  The element 3 comprises at its end opposite the rod 31, relative to the widening 32, means 33 adapted to cooperate with a bar 2 also visible in Figure 29.

  The means 33 comprise a bore 36 complementary to the outer contour of a bar 2 solid or hollow visible in Figure 29 also.

  Figure 25A shows that the inside of the rod 31 is hollowed in the longitudinal direction.

  Thus, a centered longitudinal bore of the rod 31 comprises on the one hand a zone 310 for receiving the head 72 of a screw 7 visible in FIG. 28, and on the other hand a channel 311 for receiving the threaded rod 71 screw 7.

  The channel 311 opens out and is referred to by the end of the channel 311 situated opposite the zone 310 for receiving the head 72.

  Figure 25B shows an embodiment of the element 3 cooperating with a hollow bar. In this embodiment there is a groove 37 for cooperation with the end of the bar. In this embodiment, there is no need to have a receiving area of the screw head, this head can indeed be accommodated in the bar. Of course, the element 3 comprises the channel 311 opening.

  Figures 24A to 29 also show that the cross section of each passage 11 and the outer contour of each rod 31 also comprise two arcuate portions 23 opposite to each other. They also comprise two rectilinear portions 24 parallel and opposite one another and connecting the arcs of circle 23.

  FIG. 26 shows that the threaded rod 71 of the screw 7 is able to cooperate with a bore 41 made in an element 4.

  As in the other embodiments, the element 4 has a longitudinal profile 43 any decorative, for example of rounded or pointed, and having at its base an enlargement of section 45, for example in the form of a bead.

  The element 4 comprises a bore 42 which cooperates with the outer contour of the rod 31. The element 4 is locked in rotation due to the truncated circular contour cooperating with the rod 31. A shoulder 44 reduces the cross section of the bore 42 and is adapted to cooperate with the shoulder 39.

  Figure 27 shows a bottom view of the element 4. It is thus seen that the contour of the bore 42 is preferably circular 23 truncated on two portions 24 opposite to each other.

  The bore 41 is made in the center of the element 4, in the longitudinal direction. The inner surface of the bore 41 is threaded.

  The depth of the bore 41 is preferably greater than the longitudinal extension of the rod 71 of the screw 7. Thus, the shoulders 39 and 44 cooperate so that the element 4 comes into abutment longitudinally on the element 3 when the grid does not comprise at least one decorative piece 5 which is described below and visible in FIG. 29.

  The shoulders 39 and 44 do not cooperate when the grid comprises at least one such decorative piece 5.

  Figure 29 shows more precisely the manner in which this embodiment is mounted.

  The connecting element 3 is firstly passed through a passage 11 of the crossmember 1, taking care to place a decorative part 5 if desired between the element 5 and the crossmember 1.

  The element 4 is then threaded onto the rod 31 by way of the bore 42, taking care also to place a decorative part 5 if desired between the element 4 and the crossbar 1.

  The element 3 and the element 4 are then secured, which then grips the cross-member 1, in particular via the beads 32 and 45. To do this, the screw 7 is inserted into the bore 36 in order to place the head 71 of the screw 7 in the receiving zone 310.

  The threaded rod 71 then passes through the channel 311 and the hole 312 to cooperate with the bore 41 also threaded.

  We then screw the two elements 3 and 4 together. We then pass the bar 2 in the means 33.

  It is then understood that the grid is then indémontable from the outside, since one no longer has access to the head 72 of the screw when the bar is present and the element 4 is locked in rotation due to the truncated circular contour cooperating with the rod 31.

  Figs. 30A to 34B schematically show another possible embodiment of the invention.

  FIGS. 30A to 31 show that in this embodiment of the element 3, the cooperation means 33 with a bar 2, which is visible in FIG. 34A, comprise a bore 36 passing through the bead 32 forming the widening.

  There is preferably no barrel in the cooperation means 33, although the presence of a barrel of material on the bead 32 is of course possible.

  The rod of the element 3 is different from the rods described in the preceding developments, in the sense that it is composed of two main blades 31 of substantially rectangular shape and facing each other in pairs.

  The two blades 31 are made of material on the bead 32.

  Figure 31 shows a bottom view of the element 3. It is seen in this figure that the bore 36 of the means 33 advantageously comprises a circular contour 23 truncated on two portions 24 opposite to each other.

  The blades 31 are then preferably integrally formed on the bead 32 at the right portion 24 of the contour of the bore 36.

  The blades 31 comprise at their opposite end to the bead 32 a pin 313 integrally formed on the blades 31 and extending perpendicularly to the main extension direction of the blades 31.

  FIG. 32A shows that the element 4 comprises a non-through bore 42 whose contour cooperates with a bar contour 2.

  The decorative profile 43 of the element 4 also preferably comprises a bead 45 at the base of the element 4.

  The top 46 of the element 4 may be of any decorative shape, for example in the shape of a trident as shown in FIG. 32A.

  Figure 32B shows a bottom view of the base of the element 4.

  The base of the bore 42, located in the bead 45, has a profile 47 complementary blades 31 and for receiving the blades 31 in the bore 42.

  Preferably three levels of grooves 48 capable of cooperating with the lugs 313 of the element 3 are formed in the profile 47. The grooves 48 therefore extend perpendicularly with respect to the longitudinal axis of the element 4.

  FIG. 33 shows that the passages 11 of the crosspiece 1 also comprise a profile 26 adapted to cooperate with the blades 31 and the lugs 313 of the element 3.

  Thus, as shown in FIG. 34A, the blades 31 of the element 3 are initially inserted into a passage 11 of the cross-member 1. Care is taken to place before this operation a possible decorative part 5 between the widening 32 and FIG. 34B shows that a decorative piece 5, two decorative pieces 5 or no decorative piece 5 can be placed on the grid.

  The element 4 is then inserted on the element 3 by making the blades 31 cooperate with the bore 42. Of course, care is taken to place, if desired and as shown in FIG. 34A, a decorative piece. 5 between the bead 45 is the crossbar 1.

  The lugs 313 are then cooperated with the grooves 48. The cooperation of the lugs 313 and the grooves 48 is facilitated by the fact that the blades 31 are relatively flexible and in that the bar 2 is not yet in place in the lug. element 3.

  If no decorative part 5 has been placed on the grid, the lugs 313 cooperate with the series of grooves 48 located furthest from the crossbar 1, since the element 4 fits a long distance on the element 3 If a decorative piece 5 has been placed on the grid, as is the case in Figure 34A, then the lugs 313 cooperate with the intermediate grooves 48. If two decorative pieces 5 have been placed, then the lugs cooperate with the grooves placed near the opening of the bore 42.

  A bar 2 is then inserted into the means 33, the bar passing through the element 3 into the bore 42 of the element 4.

  Once the bar is mounted, the pins 313 can not be removed from the grooves 48. This is shown in Figure 34A.

  The grid is therefore indémontable from the outside, since when the bar 2 is in place, it is no longer possible to remove the lugs 313 from the grooves 48. As shown in FIG. 32A, the element 4 preferably comprises means 420 capable of ensuring a force fit of the bar 2 in the bore 42. The means are preferably located at the end of the bore 42.

  For example, the force-mounting means 420 may be in the form of protuberances or grooves extending longitudinally with respect to the bore 42. These grooves crush during the mounting of the bar 2 in the bore 42 and thus prevent the bar 2 from being easily removed from the bore 42. A friction lock is thus effected.

  Of course, it is possible to glue the bar 2 in the bore 42.

  Figures 35 to 40 show another possible embodiment of the invention.

  FIG. 35 shows that the element 4 comprises at the base of its bore 42 preferably three series of grooves 48 whose extension is perpendicular to the longitudinal axis of the bore 42.

  FIG. 36 shows a radial sectional view of the lower part of the element 4, at the level of the bead 45.

  It can be seen in FIG. 36 that each groove 48 is of limited extension and covers a quarter of a circumference, ie a circular arc of approximately 90.

  Each series of grooves 48 comprises two grooves 48. The beginnings of each groove 48 are diametrically opposed in pairs, the ends of each groove 48 are also diametrically opposed as shown in FIG. 48.

  Two grooves 49 whose extension is along the longitudinal axis of the element 4 connect together the beginnings of each series of grooves 48.

  The grooves 48 are able to cooperate with lugs 313 made of material on the rod 31 of the element 3 visible in Figures 37 and 38 in particular. The rod 31 is itself material on the enlargement 32.

  The lugs 313 are substantially of rectangular shape and extend radially with respect to the rod 31. The long sides of the lugs 313 follow the internal profile of the grooves 48 and grooves 49.

  The means 33 do not have a shank, but preferably only a bore 36 passing through the shank 31.

  Figure 39 shows that the element 3 can be mounted in one piece with a decorative pattern 52, the representation is not limiting. The enlargement is then materialized by a plate 53 made of material on the base of the rod 31.

  The assembly of the gate is shown more precisely in FIG.

  The element 3 is inserted in a passage 11 of the crossbar 1. Of course, the contour of the passage 11 cooperates with the profile of the rod 31 and passes the lugs 313.

  Care is then taken to place the decorative pieces that are desired between the widening 32 and the cross member 1. According to one variant, the element 3 of FIG. 39 is used.

  The element 4 is then placed on the rod 31. The lugs 313 are then cooperated with the grooves 49 in order to drive the element 4 onto the rod 31.

  Once the element 4 is placed at the right height on the rod 31, the lugs 313 are at the right of a pair of grooves 48.

  The element 4 of 90 is then rotated around a longitudinal axis to the element 4.

  After the rotation, each lug 313 is in a groove 48 and because of the rotation of the element 4, no lug 313 is in cooperation with a groove 49. Consequently, the element 4 can not be removed from the groove 49. the stem 31.

  Figure 36 shows that the inner bore 42 preferably comprises a truncated circular profile.

  The orientation of the planar and circular portions 23 with respect to the grooves 49 is such that the bar 2 can not be driven into the bore 42 until the rotation of the element 4 of 90 has been effected.

  Once the rotation has been completed, the bar 2 is introduced into the bore 42.

  Once the bar 2 is introduced into the bore 42, it is no longer possible to dismount the element 4 of the rod 31 since a reverse rotation of 90 which would make it possible to put the lugs 313 at the grooves 49 is no longer possible.

  Indeed, the bar 2 is locked in rotation due to the cooperation of the truncated circular profiles of the bar 2 and the means 33 of the element 3. Similarly, the element 3 is also locked in rotation due to the cooperation of truncated circular profiles of element 3 and passages 11.

  In addition, in the case where the outer contour 43 of the element 4 and the bar 2 comprise a truncated circular profile, care is taken to place planar profile 24 of the element 4 with respect to the grooves 49 so that the flat profiles 24 of the element 4 and the bar 2 correspond after the rotation of 90 for mounting the grid.

  The element 4 preferably comprises means capable of ensuring a force fit of the bar 2 in the bore 42. The means are preferably located at the end of the bore 42.

  For example, the force mounting means may be in the form of protuberances or ridges extending longitudinally with respect to the bore 42. These streaks crush during the mounting of the bar 2 in the bore 42 and prevent as well as the bar 2 can easily be removed from the bore 42. A friction lock is thus performed.

  Of course, it is possible to glue the bar 2 in the bore 42.

  The part or parts forming the element 3, as well as the other parts of the grid according to the invention, can be manufactured in several ways. This may be for example a molding technique or injection foundry metal, plastics, resin or glass fibers. It can also be a part machining technique.

  Each crosspiece 1, each bar 2, each connecting element 3, each element 4 or part 5 is made of metal, aluminum, plastics, PVC (polyvinyl chloride), fiberglass, resin or composite material. example. The crossbar 1, the bars 2, the connecting element 3, the element 4 and the decorative part or parts 5 can be made of wood, for example.

  The foregoing developments advantageously apply to a grid comprising one or two crosspieces 1 and at least one bar 2. It is understood that it is possible to fix other crosspieces, for example by fixing them on the bars 2. It is possible to also provide to mount several grid according to the invention on each other, according to several floors.

  The invention notably has the advantage that the laying of the grid to measure is mainly done by assembling three elements 1, 2 and 3, or even four elements by adding to the three elements 1, 2 and 3 the element 4 in some embodiments. The necessary tools are at most a hacksaw. Once the elements are nested, they are indémontables. The grid adapts to all dimensions of bays or fences.

  The invention is advantageously sold as a ready-to-assemble set comprising all or part of the elements described above.
