Description

[0001] COATINGS OR COVERINGS FOR FINISHING SURFACES AND STAPLES FOR CONNECTING THE ELEMENTS THAT COMPOSE IT

[0002] DESCRIPTION

[0003] The present invention relates to clips for surface coverings and to surface coverings comprising such clips. The present invention also relates to coverings or linings for exterior and interior surfaces and means for securing them.

[0004] Surface coverings comprising a plurality of panels and longitudinal profiles are well known, with the panels and profiles typically arranged perpendicular to each other. Such coverings are also known as cladding. Clips are placed at the intersections between panels and profiles. The clips are attached to the profile, for example, by screwing their base to the profile or by inserting their base or elastic elements or legs into a groove in the profile. Furthermore, the clip has a head with two protrusions on the sides that fit into recesses or grooves located on the edge or side of the panels. In this way, each clip connects a profile to two adjacent sides. This type of covering can be suitable for vertical or horizontal surfaces and for installation in a herringbone pattern, Hungarian Point pattern, or any other installation pattern defining parallel panel patterns.It is also suitable for exterior and interior cladding, i.e. cladding that leaves a gap between adjacent parallel panels or panels where the sides or edges of adjacent parallel panels are not in contact with each other on the outermost part of the cladding.

[0005] The following documents describe coatings and staples according to the above description: ES1029540U, ES2238878A, ES1225774U and ES2504665A.

[0006] More specifically, document ES1225774U discloses a covering comprising a structure formed by a plurality of panels secured to profiles by means of clips positioned simultaneously in cavities of said panels and profiles. Said clips have a head for insertion into one of the panel cavities and an elastic body connected to the head for insertion into a cavity of the profile. The head and the elastic body are rotated relative to each other at an angle equal to or greater than 0. oand less than 90°, allowing the installation of panels, including herringbone-shaped panels. The head has resilient locking projections arranged at diagonally opposite ends of the neck of the clips. WO2015159136 discloses a covering comprising panels, fasteners, and longitudinal profiles. Each profile has a guide designed to work together with a fastener. The profile guide is composed of a slot that provides access to a cavity with larger cross-sectional dimensions than the slot. The sides of each panel have a slot into which a head of the fastener is inserted to join the profile to the panel. The base of the fastener has dimensions that allow rotation between a first and a second position when inserted into the guide slot.The clamp has a first shape with a first cross-section and a second shape with a second cross-section. The second shape dimensionally interferes with the guide in the second position (locking the clamp's position), while the first shape allows free movement along the profile in the first position. The dimensions of the clamp's head determine the separation distance between adjacent panels, defining a panel gap.

[0007] Furthermore, outdoor-appropriate cladding is also known to have a top surface with grooves between the panels to allow water, such as rainwater, to pass through. This type of cladding is also known in which, despite the grooves on the top surface, the back of the cladding is not visible. Therefore, the fixing means, such as staples, which are usually attached to a support frame, are not visible, thus improving the aesthetics of the cladding.

[0008] Patent ES 2215485 A1 discloses a cladding of the aforementioned type in which the side edges of the panels comprise indentations and protrusions on the upper part of the panel such that the cladding from the visible side does not allow the base on which the cladding is mounted to be seen, nor does it allow the fixing clips between the panels to be seen. Furthermore, the panels have clip-receiving cavities located slightly in the lower-middle part of the panel in order to save the clip's travel and, therefore, reduce production costs. Furthermore, the clips have intermediate zones that are vertical with respect to the profile.

[0009] A common problem with all these coverings is the removal of the covering, which is sometimes necessary to access hidden services beneath the covering or for repair work. When removing the panels, the panels and / or the clips can break. Even when using clips made of material with elastic properties and not screwed into the profile, some clips are sometimes damaged in the process, as the stresses can exceed the strength of the material. Furthermore, for various reasons, it is difficult to control the stress on the clip during removal.Even if it is possible to remove a panel without breaking the clip, removing and reinstalling a panel can be problematic, because the lack of space due to the presence of the clip and other panels that have not been removed makes reinstallation difficult or even impossible, so it is sometimes necessary to break the clip to allow reinstallation.

[0010] As a result, it is necessary to provide replacement panels and / or clips when performing these tasks, and if possible, they can be adapted to the different types of clipping systems available.

[0011] According to a first aspect, it is an objective of the present invention to provide a new clip that allows the removal of the covering without damaging the clip, thus allowing it to be reused.

[0012] Additionally, surface cladding is a popular choice due to its attractive aesthetics and durability. As the demand for exterior cladding has increased, so has the need for panel stocks with different surface finishes (colors, textures, etc.).

[0013] According to a second aspect, an objective of the present invention is to provide a solution to the need to house large quantities of stock with panels of different finishes. In particular, according to a first aspect, the present invention discloses a clip for surface coverings comprising panels located on profiles and clips that connect a profile with two panels, of the type comprising a head with two lateral projections for insertion into lateral grooves of panels and a base for connecting or fixing to said profile. The clip is characterized in that at least one of said lateral projections is arranged in a piece capable of movement with respect to the rest of the clip, such that said projection is at least partially movable or retractable with respect to the clip, the clip having a spring element for restoring the position of said movable or retractable projection.

[0014] Preferably, said spring element is arranged on said movable part. The function of said spring element is to exert a force opposing the movement of said movable part relative to the fixed part when it encounters a movement.

[0015] The present invention relates to the use of clips comprising two parts, one of which has at least one of the lateral projections. This part can be moved relative to the rest of the clip, such that the projection is at least partially movable or retractable. That is, thanks to the movement of the part, the projection can be inserted, at least partially, into the clip, such that it protrudes less. By being able to move, the panel can move the side that is holding it apart during the installation and removal processes. By moving the side apart, the clip cannot break.The spring element, arranged oppositely, is intended to return the movable part, and thus the movable or retractable protrusion, to its initial position. This may, in certain cases, be necessary during the installation process and advantageous during the removal process. Another function of the spring element is to provide some resistance to panel removal, since removing the panel requires overcoming the force generated by the spring element. This prevents accidental removal.

[0016] An additional advantage of the present invention is that it can be applied to numerous types of staples, since it allows the base to have any of the known typologies such as, for example, a base with a screw hole, elastic legs for insertion into a slot, or a base angled with respect to the head for fixing by turning.

[0017] Preferably, the movable part comprises both lateral projections of the clip, with the spring element located at the free end of one of the projections. In this way, the spring element encounters the walls of the slot in which the free end is housed as movement stops, generating resistance in the spring element. This, in turn, causes the spring element to generate the aforementioned force to return to the initial or neutral position.

[0018] Preferably, said movable part moves in a direction that connects both projections. Also preferably, the staple is arranged in the covering such that said movement is parallel to the outer surface of the covering. Also preferably, said direction is perpendicular to the axis that connects the head and base of the staple.

[0019] The spring element can take different forms. It can be a spring, or it can be an elastic element, such as one or several curved arms made of flexible material.

[0020] Advantageously, the clip may comprise at least one guide for guiding the movement of the movable part. Preferably, the guide comprises a slot and a mating projection. The projection may be located on the movable part and the slot on a part that constitutes the remainder of the clip, or vice versa.

[0021] The clamp may comprise a stop element that defines a neutral position. The neutral position may preferably be the normal installation position. In the neutral position, the stop element may generate a force that must be overcome to initiate movement of the movable workpiece. This prevents accidental or unwanted movement of the movable workpiece. It is also possible to provide the clamp with different stop elements, which are activated at different points along the travel of the movable workpiece. Preferably, the stop element comprises a flexible arm with a protruding end that is inserted into a hole or recess in the aforementioned neutral position.

[0022] To facilitate the panel's movement of the movement-capable part during the installation and removal processes, preferably at least one lateral projection located on the movement-capable part has chamfered edges.

[0023] The staple base can be of any type, for example with fixing to the profile by screwing, locking or using an elastic element.

[0024] Preferably, the staple has an intermediate region that connects the head to a base, the intermediate region being oblique with respect to the head and the base so that the head and the base are offset from each other. This embodiment is especially useful for reversible coatings or coverings.

[0025] The present invention also relates to surface coverings comprising panels positioned above profiles and clips connecting one profile to two panels, the clip comprising a head with two lateral projections for insertion into respective lateral grooves of said two panels, and a base for connection or attachment to said profile, comprising at least one clip according to the present invention. Preferably, all of the clips for joining profiles and panels are clips according to the present invention. Said lateral projections of the clip are inserted into lateral grooves of two adjacent panels. Preferably, the clip is positioned such that the movement of said clip-moving part is carried out in a direction perpendicular to a longitudinal direction followed by said grooves of the panels and which joins grooves of adjacent panels.Particularly advantageously, the spring element faces a bottom wall of one of said grooves, such that they can exert said resistance to movement.

[0026] In the present invention, the term "profile" is understood to mean any type of element suitable for fixing the cladding clips. According to a second aspect, in particular, the present invention discloses a cladding comprising multiple panels connected by clips to a fixing frame, the panels being arranged parallel to each other and in the same plane, the panels having cavities in the lateral edges, the cavities of adjacent panels being arranged opposite each other for receiving the clip, the adjacent panels being arranged in such a way that a slot is formed between adjacent lateral edges of two adjacent panels, and the lateral edges of the panels having an arrangement of conjugate recesses and protrusions, in which the clips comprise a head that is connected to the cavities of the panel, an intermediate zone that connects the head with the base and a base for joining to the fixing frame, preferably to profiles,characterized in that the cavities are located at a midpoint of the corresponding panel and because the shape of the conjugated recesses and projections has the path of the slot, presenting a symmetry with respect to the central point of the same and because the intermediate zone of the staple has a shape that follows the path of the slot.

[0027] Therefore, the present invention provides for the implementation of panel coverings featuring symmetrical grooves and cavities, as well as for the optimization of the mounting clip characteristics to provide precise alignment and solid fixation. The panels are reversible, and the same clips can be used on both sides of the panels, allowing panels with a different surface finish on each side to be produced, thereby halving the required panel stock.

[0028] Therefore, the present invention allows for the production of a single type of panel that can be reversible, thereby reducing the costs associated with producing different types of panels. Furthermore, each side of said panel can preferably have a different finish.

[0029] The present invention offers an innovative solution for achieving reversibility for groove cladding that obscures the view of the connecting clips, while maintaining the ease of installation of the surface cladding. This represents a significant advance in the field of construction and architectural design. Symmetries with respect to the center point can be of various types. In preferred embodiments, the groove exhibits axial symmetry with respect to the median plane of the panel. In preferred embodiments, the groove exhibits central symmetry with respect to the median plane of the panel.

[0030] In certain embodiments, the groove has an oblique path on both sides of the cavities relative to the upper surface of the liner. In certain embodiments, the groove has a zigzag path, i.e., with two vertical sections and one oblique section on each side of the cavities.

[0031] Preferably, the support frame for fixing to the element to be covered comprises a series of profiles or slats parallel to each other, and preferably located perpendicular to the panels.

[0032] In certain embodiments, the head has pairs of protrusions intended to reduce play within the receiving cavity, and the base also has a hole to receive a fixing screw or other elements equivalent to the frame. In some embodiments, the screw may be positioned parallel to the direction of the slot in its placement area. It is also possible, for example, that, in certain embodiments, the screw may be screwed in a direction perpendicular to that of the surface on which the covering is placed.

[0033] In certain embodiments, the staple head comprises two lateral projections, one of which is formed by flexible curved arms that behave as springs that, when compressed, exert a restoring force in the direction of movement.

[0034] The present invention also discloses a type of clip that allows reversibility of the panels of the cladding object of the present invention.

[0035] A new type of mounting clip is presented, specifically designed to interact with the panels of the present invention. These clips are equipped with additional features that allow the same clip to be used on both sides of the panel. The clips preferably have a thickened head intended to be inserted into the cavities of the panels, a base for attachment to a support structure, and an intermediate zone connecting the head and the base, wherein said intermediate zone is oblique with respect to the head and the base such that the head and the base are offset from each other.

[0036] The head and base being offset from each other allows the staple to follow the path of the slot left between the reversible panels object of the present invention.

[0037] Even more preferably, the head has a flat area that has projections in its free area to make contact with the wall opposite the slot of the cavity in which it is inserted.

[0038] In preferred embodiments, the staple will be made of a synthetic material. In preferred embodiments, the staple will be made of a plastic material. In preferred embodiments, the staple will be made of a metallic material. Other materials may also be suitable for the present application, or other materials whose function can be optimized.

[0078] Figure 27 shows a detail of the cross-section of another reversible covering comprising panels, a profile and a clip according to the present invention.

[0079] Figures 1 to 5 show a first example of a staple 1 according to the present invention. The staple is formed by two parts 11, 12, capable of movement relative to each other. The direction of movement is represented by line A. As can be seen in this case, movement A is parallel to the base 13 of the staple. It is also perpendicular to the main axis of the staple, which runs from the head to the base of the staple.

[0080] The fixed part 12 has part of the head and the base 13 of the clip. The purpose of the base is to be fixed to a profile or surface on which the panels that make up the exterior of the covering are placed. To do so, in this case, it has a lower hole 14 to receive a fixing screw (not shown in the figures). Since the fixed part 12 has a lightening slot 19, the hole 14 passes through said slot 19 through a passage 141, as seen in Figure 4. The fixed part 12 also has a guide system to facilitate the movement of the movable part 11. In the case shown, the guides consist of inward slots 123 that receive conjugated protrusions 113 of the movable part and direct the movement along the direction A of movement between parts, coinciding with the main direction of the slots. Alternatively, the fixed part could have protrusions inserted into conjugate slots of the movable part.Alternatively, the guide could be left in contact between the walls of both pieces 11, 12, dispensing with conjugated grooves and projections.

[0081] Optionally, interlocking elements can also be provided between the fixed part 12 and the moving part, defining a "neutral" position in which a certain force must be applied to initiate movement in direction A and / or acting as movement stops. In the example shown, clip 1 has two such interlocking systems. One is formed by the flexible arm 116, located in a hole 118, and having a head or tip 117 that is inserted into a recess located in a recess area 217 of the fixed part 12, and another by the tongue 115 connected to the rest of the mobile part by means of a transition 1151 and ending in a claw that ends introduced into a recess 215 located on one side of the fixed part 12. In the example shown, both systems are activated and deactivated at the same time, since when the tip 117 enters the recess of the recess area 217, the claw of the tongue 115 enters the recess 215.Both the tongue 115 and the flexible arm 116 can exert a spring force that must be overcome to move the movable part 11 from the neutral position shown. It would also be possible for both systems to correspond to different points within the movement of the movable part along direction A.

[0082] The movable part 11 in the example comprises both lateral projections 111, 112 of the clip. One of the projections 111 is formed by flexible curved arms behaving like springs which, when compressed, exert a restoring force in the direction of movement A. Other spring systems would also be possible. Alternatively, the projection 111 could be part of the fixed part, in which case the spring (e.g. lateral projections 111 similar to those in the example) would be in either the movable part or the fixed part.

[0083] The fixed part 12 in the example also has a hole 114 that provides access to the hole 14 of the fixed part for receiving a fixing screw (not shown in the figures). The aforementioned flexible arm 116 is also located in this hole. In the fixed part in the example, the head and base 13 are separated by a neck 132.

[0084] Figures 6 to 8 show the removal of a panel 100 from a siding according to the present invention, with clips similar to those shown in Figures 1 to 5. Figure 9 illustrates the reinstallation of the removed panel from the siding.

[0085] The covering shown in Figures 6 to 9 is formed by panels 100 arranged on a base or profiles 200. The profiles 200 are preferably perpendicular to the panels 100. The panels 100 have grooves 101, 105 on their sides. By arranging the slots 101 , 105 in an intermediate part of the edge or side of the panels 100, on both sides of each slot 101 , 105, projections 102, 103, 104, 106 are defined. As can be seen, the shapes of the edges of the adjacent panels are conjugated, and the relative placement of the panels 100 which, in the case shown, leave a slot 300. The assembly is joined by clips 1 as shown in figures 1 to 5, which are screwed to the profiles 200 at the points of intersection with the panels 100. The clips are introduced into the slots 101 , 105 of adjacent panels, in such a way that each clip 1 is fixed to a profile 200 and to two adjacent panels 100.In particular, each of the lateral projections 111, 112 of the head is inserted into a slot 105, 101 respectively. The initial installation of the cover can be carried out following conventional methods that do not require the staple to have two parts that move relative to each other.

[0086] Figures 6 to 8 show the removal of a panel 100 from a covering formed by panels 100 and base elements such as, for example, profiles 200. As can be seen, the covering comprises clips as shown in Figures 1 to 5. Each group joins a profile 200 with two adjacent panels 100. The lateral projections 111, 112 of each clip are inserted into corresponding slots 105, 101 located in the edges of the panels. As can be seen, to remove a panel 100, a spatula-shaped tool 1000 is inserted into the slot between adjacent panels and leverage is applied by exerting a force in the direction indicated by an arrow in Figure 6.This causes the panel to rise and press on the lateral projection 111, which, due to its ability to move with respect to the rest of the clip, retracts, leaving the panel free to move forward on its exit path and thereby crushing the spring element of the other lateral projection 112 (Figure 7). Once the panel has risen sufficiently, the lower projection 102 of the panel stops pressing on the lateral projection 112 of the clip and, due to the action of the elastic element, the clip returns to its initial position (Figure 8).

[0087] For reinstallation of the panel after uninstallation of a panel, and as seen in Figure 9, top line, once the position shown in Figure 9, top line is available, the panel 100 to be placed is pressed against the corresponding clip 1 or clips. This pressure causes the lateral projection 112 and therefore the movable part to move towards the adjacent panel. It can be seen how the projection 112 retracts, moving towards the interior of the clip. Since the movable part comprises both projections 111, 112 of the clip, the retracting of the pressed lateral projection 112 causes the other lateral projection 111 to be inserted further into its slot 105, such that the elastic element of the lateral projection 111 inserted into said slot 105 of the adjacent panel is compressed (intermediate line of Figure 9).Once the lower projection 102 of the panel 100 being introduced surpasses the staple head, the projection 112 pressed by the panel 100 being introduced is at the height of the corresponding slot 101 of the panel being introduced. At that moment, the elastic element of the lateral projection 111 that had been compressed pushes the movable part 11 towards the interior of the slot 105, such that we obtain the final position of the lower line in figure 9. In the uninstallation process, the reverse process is followed.

[0088] It can be seen how it is advantageous that the projection 112 of the clip 1 that does not have an elastic element has chamfered edges, to facilitate the panel 100 pushing in the direction of relative movement between the moving part and the fixed part of the clip in the assembly and disassembly process.

[0089] Figures 10 to 12 show another embodiment of a staple in which the base 13 of the staple is not screwed, but rather has an elastic element 2 for fixing to a profile of a known type that is inserted into a longitudinal groove in the profiles of the covering to which it is directed. The elastic element is formed by a neck 136, 136' that gives way to respective clavicles 137, 137' and shoulders 138, 138' that give way to two curved arms 139, 139' of an elastic nature. The remaining elements of the staple are similar to those of the embodiment in Figures 1 to 5, so they have been identified with identical numerals and will not be explained in depth.

[0090] Figure 13 shows an alternative staple 1 to those shown in previous figures. Elements identical or equal to those shown in previous figures have been represented with identical numerals and, therefore, will not be explained in detail. The moving part 11 is identical to those shown previously, as is the fixed part 12 in its interconnection parts with the moving part 11. However, the base of the staple 1 is modified to facilitate its introduction into a slot of a profile and its extraction without the need to break elements or screw them. In particular, the slot has a neck 136, in this case rounded, and of reduced dimensions; in particular, said dimensions must be smaller than those of a slot in the profile or base on which the cover and the staple are located (profile with slot not shown in the figures), and must allow the neck to rotate within said slot.After the neck 136, the staple 1 has an elongated base 147 with dimensions larger than those of the neck 136. The function of the base 147 is to be located in the cavity or guide of a slat, profile or base, being able to rotate within it. To this end, the smaller dimension of the base 147 will be smaller than that of the slot of the slat, profile or base, while the larger dimension will be larger. After the base 147, the staple has a foot 148 with a rounded tip 149 to facilitate contact fixing and sliding along the slot of the profile or base. This staple has the installation and removal advantages shown in document WO2015 / 159136.

[0091] Figures 14 and 15 show a clip 1 like the previous ones, adapted to "Hungarian point" type cladding or coverings, i.e., those in which the panels 100 have a right angle. Consequently, the geometry of the head of the clip 1 also has a right-angle shape. Elements identical or similar to those shown in other figures have been represented with identical numerals and will therefore not be explained in detail. Likewise, the clip has been represented schematically, making it possible to apply details identical or similar to those shown in the previous figures to the mobile parts 11 and fixed parts 12 that make up the clip 1.

[0092] Figure 16 shows an example of two adjacent panels 1001. Both panels 1001 comprise cavities 1002 in the lateral edges opposite each other to fit with the edges of the clips. In this figure 16, the clips and the base elements are not shown. Said cavities 1002 are placed in the central area of ​​the panel 1001 in such a way that the cavity is equidistant from the surface of the upper and lower edges of the panel 1001. The two panels 1001 are equal and are arranged opposite each other on the opposite side of the other panel 1001. This arrangement of the two panels 1001 forms a slot 1003. The panel 1001 on the left has two projections 1004, 1006 with respect to the upper part of the slot. One of the projections 1004 is located above the cavity 1002 and the other projection 1006 is located below it.Correspondingly, the right-hand panel 1001 has two recesses 1005, 1007 which are aligned with the projections 1004, 1006 of the adjacent panel and face each other, such that a slot 1003 is formed between panels 1001. The slot 1003 has an approximately constant width except in the area of ​​the cavities 1002.

[0093] As can be seen, the shape of the side edges of panels 1001 and in particular the shape and arrangement of projections 1004, 1006 and recesses 1005, 1007 and cavities is such that slot 1003 presents central symmetry. This means that if both panels 1001 are inverted, the arrangement of slot 1003 is mirror-image with respect to that shown in Figure 16, which will allow the same clip 1 to be used to fix the inverted panels 1001.

[0094] Figures 17 to 19 show another embodiment of clip 1 applicable to a reversible covering, such as that shown in Figure 16. Similar to the clips shown in Figures 1 to 15, clip 1 has a fixed part 11 and a moving part 12. Likewise, the moving part 11 has flexible projections 111 like those shown in Figures 1 to 15. The shape of the base of clip 1 allows it to slide along a slot in the profile or base on which the covering or coating is fixed, similarly to the clip shown in Figure 13. Elements equal to or similar to those shown in the previous figures have been represented with identical numerals and, therefore, will not be explained in detail. Likewise, staple 1 has been represented schematically, and the details shown in figures 1 to 15 can be applied to it, both in relation to the shape of the head or the base, or the characteristics of the pieces 11, 12 and their interconnection.

[0095] Figure 17 shows a covering formed by the same panels 1001 as in Figure 16 and a fixing frame comprising base elements in the form of a profile 1009. The profiles 1009 are arranged perpendicular to the longitudinal axis of the panels 1001. The assembly is joined by clips 1. The clips 1 are joined to the profiles 1009 at the points of intersection with the panels 1001. The clips 1 are also introduced into the cavities 1002 of adjacent panels, such that each clip 1 is fixed to a profile 1009 and to two adjacent panels 1001. As can be seen, the shape of the conjugate projections 1004, 1006 and recesses 1005, 1007 is such that the vertical line of sight falls on one of the panels 1001, which makes the clip 1 not visible.

[0096] In Figure 17, an arrow shows that panels 1001 can be flipped so that their lower surface is exposed. In this example, slot 1003 would be arranged mirror-image relative to that shown in Figure 17, so that clip 1 can be used in the flipped configuration by placing it rotated relative to that shown in Figure 17.

[0097] Figure 18 shows the profile 1009 and the clip 1 of Figure 17. In this embodiment, the base element has a projection that allows its introduction through the slot of the profile and subsequent rotation of the clip 1 for fixing it in the profile 1009.

[0098] Profile 1009 may vary from that shown in the figures, and may be a profile that can be used for different types of staples 1008.

[0099] As can be seen in Figures 19 and 20, the clip 1 is formed by three elements 10, 11, 12: a head 1010, an intermediate zone 1011 and a base 1012. The intermediate zone 1011 that connects the head 1010 with the base 1012 is oblique, such that the head 1010 and the base 1012 are offset from each other. This allows the clip 1 to be used with the panels 1001 shown in the previous figures.

[0100] In this example, the head 1010 is movable relative to the rest of the staple 1. The head 1010 of the staple 1 comprises two lateral projections 1013, 1014. In particular, each of the lateral projections 1013, 1014 of the head is inserted into a cavity 1002 of the panel respectively. The panel 1001 presses one of the lateral projections 1014, allowing its introduction. One of the projections 1013 is formed by flexible curved arms that behave like springs that, when compressed, exert a play restoring force in the direction of movement. Other spring systems would also be possible. Alternatively, the projection could be part of the intermediate zone 1011 or base 1012, in which case the spring (for example lateral projections similar to those in the example) would be in the head 1010 or base 1012.

[0101] The base 1012 is intended to be fixed to a profile 1009 or surface on which the panels 1001 that make up the exterior of the cladding are placed, and can change depending on the surface to which it must be fixed.

[0102] Staple 1 in the example is made of flexible material, preferably plastic, which allows for elastic deformation of the head's lateral projections 1013 and 1014. Other materials are also possible.

[0103] Clips 1 can be placed on profiles 1009, and then panel 1001 can be installed by pressing clips 1008 into profiles 1009, deforming the legs of clips 1008 with a vertical movement. Other insertion methods are also possible.

[0104] Figures 21 to 23 show yet another embodiment of a cover and a clip. Elements identical or equivalent to those shown in the previous figures have been identified with identical numerals and will not be explained in depth. Clip 1 in this example also comprises a movable part 11 and a fixed part 12, as in the previous examples. The movable part 11 comprises flexible projections 111 formed by flexible curved arms that behave like springs which, when compressed, exert a restoring force that fixes the head in the corresponding slot. In particular, when compressed by the bottom wall of the cavity 1002 into which they are inserted, the flexible projections 111, 111' push the opposite projection 112 of the movable part 11 against the bottom of the corresponding slot or cavity of the adjacent panel 1001.Likewise, the fixed part 12 of the clip 1 comprises an intermediate zone or oblique neck, similar to the clip shown in Figures 17 to 20. In this case, the clip 1 is fixed to a profile or base by means of a screw 1015. To this end, the clip may have a hole in the base. Figure 23 shows the dimensional interference existing between the projections 111 , 111 ' and the cavity, that is, the deformation of the projections caused by the interference of the back wall of the cavity 1002 has not been shown. This embodiment complies with the two aspects of the invention mentioned above, that is, it allows rapid disassembly and, in addition, application to reversible coatings or coverings. Although this embodiment has been represented in a simplified manner, any of the characteristics shown in Figures 1 to 20 above may be included in the parts that make up the clip 1.Likewise, the clip 1 can be adapted to any of the panels 100, 1001 shown in this description.

[0105] Figures 24 and 25 show another embodiment of the sheathing. While Figures 17 to 20 show an embodiment of the clip 1008 in which the base 1012 of the clip 1008 is not screwed, in Figures 24 and 25 the clip 1008 is screwed into the frame or fixing structure. In this document, the terms frame and structure are used synonymously. For example, the frame may be a series of solid slats or parallel profiles 1009.

[0106] In Figure 24, two adjacent panels 1001 are shown having two cavities 1002 in the lateral edges and a slot 1003 that separates the panels 1001 in the form of a generally oblique path with respect to the plane in which the profiles 1009 are arranged. In addition, said covering has a profile 1009 perpendicular to the panel 1001 and a clip 1008 joined to the profile 1009 with a screw 1015. The intermediate zone 1011 of the clip 1008 follows the path of the slot 1003 between the cavities 1002 and the profile 1009. For the panel 1001 on the left, there are two projections 1004, 1006 and for the panel 1001 on the right, two recesses 1005, 1007, forming a slot 1003. The projections 1004, 1006 and recesses 1005, 1007 of panel 1001 have an oblique path. In this example, panels 1001 are identical to those used in the example in Figures 16-20.As can be seen, the shape of the conjugate projections 1004, 1006 and recesses 1005, 1007 is such that the vertical line of sight falls on one of the panels 1001, making the staple 1008 not visible. In addition, the head 1010 of the staple 1008 has pairs of bulges 1016 intended to reduce the play inside the receiving cavity 1002.

[0107] In Figure 25, the clip 1008 of Figure 24 is shown, formed by three elements 1010, 1011, 1012: a head 1010, an intermediate zone 1011 and a base 1012. The intermediate zone 1011 that connects the head 1010 with the base 1012 is oblique, such that the head 1010 and the base 1012 are offset from each other. This allows the clip 1008 to be used with the panels 1001 shown in the previous figures.

[0108] In this example, the head 1010 has pairs of bulges 1016 intended to reduce the play inside the receiving cavity 1002.

[0109] The base 1012 in the example also has a hole 1017 to receive the fixing screw not shown in the figure. The base 1012 of the staple 1008 is offset relative to the head 1010.

[0110] In figures 26 and 27, the elements equal to or similar to those in figure 24 have been identified with identical numerals to those in said figure and, therefore, will not be described in detail.

[0111] In Figure 26, two adjacent panels 1001 are shown having two cavities 1002 in the side edges and a slot 1003 between the panels 1001 in a zigzag shape, that is, with two vertical sections and an oblique section on each side of the cavities 1002. The panel 1001 on the left has two recesses 1018, 1019 and the panel 1001 on the right has two protrusions 1020, 1021 conjugated and facing these. The shape of the protrusions and recesses forms the zigzag path of the slot 1003. As can be seen, the shape of the conjugate protrusions 1020, 1021 and recesses 1018, 1019 is such that the vertical line of sight falls on one of the panels 1001, which makes the staple 1008 not visible. In addition, the head 1010 of the staple 1008 has pairs of bulges 1016.

[0112] As can be seen, the shape of the side edges of panels 1001 and in particular the shape and arrangement of projections 1020, 1021 and recesses 1018, 1019 and cavities is such that slot 1003 presents central symmetry. This means that if both panels 1001 are inverted, the arrangement of slot 1003 is mirror-image with respect to that shown in Figure 16, which will allow the same clip to be used to fix the inverted panels 1001.

[0113] In Figure 27, two adjacent panels 1001 are shown having two cavities 1002 in the side edges and a slot 1003 between the panels 1001 in an oblique manner. The recess 1022 of the left panel 1001 prevents the clip 1008 from being seen from above the siding. The left panel 1001 has a recess 1022 and a projection 1023 and the right panel 1001 has, respectively, a recess 1025 and a projection 1024. In this example, the projections 1023, 1024 of each panel 1001 face the respective recesses 1022, 1025 of the adjacent panel 1001, such that the slot 1003 changes direction in the area of ​​the cavities 1002 of the panels 1001. As can be seen, the shape of the conjugate projections 1023, 24 and recesses 1022, 1025 is such that the vertical line of sight falls on one of the panels 1001, making the staple 1008 invisible. Furthermore, the head 1010 of the staple 1008 has pairs of bulges 1016.

[0114] As can be seen, the shape of the side edges of the panels 1001 and in particular, the shape and arrangement of the projections 1023, 1024 and recesses 1022, 1025 and the cavities is such that the slot 1003 presents axial symmetry with respect to the median plane of the panel 1001. This means that if both panels 1001 are inverted the arrangement of the slot 1003 will be the same as that shown in Figure 16, which will allow the same clip to be used to fix the inverted panels 1001. However, in this case, the screw 1015 is arranged obliquely with respect to the profile 1009, that is, in the same direction as the intermediate zone 1011 of the clip 1008, and following the direction of the slot 1003 in the area where the screw is placed.

[0115] The embodiments shown in the figures also constitute an illustration of the second aspect of the present invention disclosed in the introduction.

[0116] The present invention is applicable to both horizontal surfaces (ceilings, floors) and vertical surfaces (walls).

[0117] The present invention is valid for panels 100, 1001 of all types of material.

[0118] Although straight grooves have been shown, it is also possible for the projections and recesses of the side edges of the panels to have rounded areas, such that the groove path has curved areas, always respecting the objective of preventing the staples from being seen from the upper area to the cladding.

[0119] Those skilled in the art will appreciate the numerous advantages and features derived from the present invention.

[0120] The elements of the present invention, as they are not fixed in an absolutely immovable manner to each other (the elements are only fitted together) absorb the natural expansion movements of the composite, wood or any other material in both directions of its dimension.

[0121] The elements comprising the installation can be dismantled, restored in a workshop and then reinstalled in their original locations, thereby avoiding the cumbersome task of on-site restoration while also recovering the initial quality due to the greater ease of restoration in a workshop or factory. Furthermore, the environmental impact of home restoration, with its lack of waste purification and filtering facilities, is avoided. Although the invention has been presented and described with reference to embodiments thereof, it is understood that these are not limiting of the invention, and that therefore multiple construction or other details could be variable and may become apparent to those skilled in the art after interpreting the material disclosed in this description, claims and drawings.Thus, all variants and equivalents will be included within the scope of the present invention if they can be considered to fall within the broadest interpretation of the following claims.
