DESCRIPTION

[0001] The present invention relates to a device, a method and an anchoring system for panels and similar covering or cladding elements, in particular, although not exclusively, cladding panels for shipbuilding. [0002] It is known that in shipbuilding, as well as in other areas, the use has become widespread of panels to cover walls or ceilings that can be detached from, or attached to, corresponding complex load-bearing structures in order to allow for the removal thereof for maintenance or replacement, or to allow for access to the installations behind them, where provided. Currently, when screws are not to be used, pressure anchoring devices are used that are arranged, respectively, on the panels and on the associated support structures. These devices have a radially elastic male part, which can be fixed to the back of the panels by means of screw fixing or other types of members, and a female part, which is correspondingly arranged on the structure whereto the panels are to be coupled and locked using screws or other systems. By exerting an adequate non pre-determinable pressure, the male part of the device is forced into the female part, thereby determining the coupling of the panels to the destination structures. The removal of the panels is performed with the use of a suction cup. Removal results in the panels falling vertically without any protection, without it being possible to use a retention system.

[0003] The main purpose of the present invention is to propose an anchoring device for cladding panels that has been improved both in terms of fixing reliability and effectiveness and in terms of convenience of use and safety.

[0004] This result has been achieved, according to this invention, by adopting the idea of implementing a device, a method and an anchoring system having the characteristics indicated within the independent claims. Further characteristics of the present invention are the object of the dependent claims.

[0005] By virtue of the present invention, it is possible to implement a system for the anchoring of cladding panels to related support structures in a simple, reliable, rapid and accurate manner. Advantageously, the uncoupling of the panels is done in two steps: the first with a movement (vertical or horizontal depending upon the horizontal or vertical mounting of the panels) to overcome the thickness of the adjacent panels; the second with a movement that is orthogonal to the preceding movement that, particularly in the case of horizontally mounted panels, allows for the safe uncoupling of the panels. It is possible to avoid the uncontrolled uncoupling of the panel by virtue of the possibility of slightly tilting it in relation to the anchor point where the panel is coupled. In addition, it is possible to distance the panels from the relative structures thereof without necessarily having to remove them altogether. In addition to this, there is the fact that an anchoring device according to the present invention has improved operational safety characteristics due to the presence of an internal brake that prevents the free sliding of the piston, which turns out to be particularly advantageous when it is required to clad horizontal structures such as ceilings and similar structures. Furthermore, an anchoring device according to the present invention is advantageously usable in a wide range of applications, including shipbuilding, civil buildings, the decor of stores and offices, the construction of exhibition stands and for the preparation and furnishing of bars, restaurants, discos, cinemas and similar environments, particularly when the panels comprise, in whole or in part, a sound-absorbing cladding material.

[0007] Reduced to its essential structure and with reference to the figures of the accompanying drawings, an anchoring device (D) according to the present invention comprises a tubular body (1 ) whereinto there is inserted, along the respective longitudinal axis, a piston (2) whereupon there acts a mechanical brake that is suitable for preventing the free sliding thereof within the tubular body (1 ). In the accompanying drawings the reference "C1" indicates the channel within the tubular body (1 ) wherein the piston (2) slides.

[0008] According to the example shown in the attached drawings, said mechanical brake is formed by two spring plungers consisting of two grub screws (3) with an internal spherical spring piston (30) which are arranged, and which act, in diametrically opposite positions within corresponding threaded holes formed within a base portion (10) of the tubular body (1). The pressure exerted by the plungers (3, 30) on the piston (2), and consequently the braking action exerted on the latter, can be altered in adjusting the position of the plungers within the respective holes (11). To this end, the plungers (3, 30) have an end (31 ) that is shaped such as to be engaged by a tool, for example, a screwdriver. The pressure, i.e. the braking action, exerted upon the piston (2) can be adjusted depending, for example, upon the weight of the panels (5) which, as further described below, constitute a cladding surface anchored to a support structure by means of a plurality of anchoring devices (D) according to the present invention. In the example shown in Fig. 17, the piston (2) is braked by a single radial plunger (3, 30). Both in the case wherein only one plunger is used and in the case wherein several plungers are used, these are integrated into the tubular body (1).

[0009] Preferably, said base portion (10) of the body (1 ) is of a greater diameter than the part above, forming an annular projection which defines the lower part of the same body (1 ).

[0010] Furthermore, preferably, an additional annular projection (11 ) of a smaller diameter than the diameter of the body itself (1 ) is formed on the upper part of the body (1 ).

[0011 ] In accordance with the example shown in the accompanying drawings, the piston (2) has a throat (20) on the lower end thereof at a predetermined distance from the respective free end (21 ).

[0012] The piston (1 ), braked as mentioned above, can slide axially inside the tubular body (1 ).

[0013] Above, i.e. on the side opposite the free end (21 ), the piston (2) has a head surface (22) of a larger diameter that is intended to interfere with a corresponding lower abutment surface (12) within the tubular body (1) in order to avoid the disconnection of the piston (2) from the same tubular body (1 ).

[0014] The piston (2) is longer than the tubular body (1 ) whereinto it is inserted. In particular, the length of the piston (2) is such that, when the piston (2) is in the fully retracted position (as schematically shown in Figs. 1 ,4,7 and 9), the throat (20) is below the base (10) of the tubular body (1 ) at a predetermined value (d). For example, the length (L2) of the piston (2) exceeds the height of the tubular body (1 ) by two centimeters, i.e. said value (d) is equal to two centimeters (d = L2-L1 ). [0015] On the head of the tubular body (1 ), and preferably on said annular projection (11 ), an elastically flexible lamina (4) can be applied, the function thereof is described below. Said lamina (4) has a central part (40), wherein the positioning on the body (1 ) is parallel to the upper base of the latter, and two wings (41 ) which are tilted at a predetermined angle (a) in relation to the central part (40). When in position on the body (1 ), said wings (41 ) are oriented towards the lower part (10) of the latter. The central part (40) of the lamina (4) has a central hole that allows for the positioning thereof upon the annular projection (11 ). This is such that the latter passes through this hole. The fixing of the lamina (4) to the body (1 ) can be implemented, for example, by means of an O-ring (42) which for simplicity is only shown in Fig. 7.

[0016] In practice, said lamina (4) constitutes an elastically flexible appendage arranged on the head of the tubular body (1 ).

[0017] The device of the invention can be used to anchor a panel (5) to a corresponding support structure (6) in such a way that it can be removed.

[0018] More particularly, the lower part of the piston (2) is configured to firmly engage with the panel (5), and the body (1) is configured to firmly engage with the structure (6). In general, as a function of the size of the panel itself, several anchoring devices are used to secure the panel (5) to the structure (6).

[0019] With reference to the example shown in the accompanying drawings, several anchor points are arranged at the rear part of the panel (5) that are defined by corresponding plates (7), wherein each thereof has a central body having a substantially rectangular shape with two long sides (70), two short sides (71 ) and two diagonal bevels (72) joining each long side to a corresponding short side, and two wings (73) parallel to the central body and spaced apart from the latter by means of connecting surfaces (74) that are orthogonal both to the wings and to the central body. The wings (73) also have a bevel (75) that connects a short side with a corresponding long side. Each plate (7) is positioned within a recess (50) having a substantially oval- shape that is formed, for example, by means of milling, at the rear part of the panel. Such a recess (50) has a central part that extends from the spine (51) of the panel (5) to a predetermined depth (P50), and a less deep perimeter portion, which extends from the bottom of the groove (50) up to at a lesser height (P51 ) in such a way as to define a guide (S5) for the positioning of the plates (7) on the panel (5) as further explained below. The guide (S5) in the example described is a guide having a substantially oval-shape and formed at a predetermined distance from the back (51) of the panel (5) and a height (P51 ) that is compatible with the thickness of the wings (73) of the plate (7).

[0020] In a first step for applying the plates (7), they are arranged in such a way that the respective long sides (70) thereof are parallel to the major axis of the groove (50), as schematically shown in Fig. 5. Subsequently, the plates (7) are rotated 90°, parallel to themselves, as schematically shown by the "R7" arrow in Fig. 6a, in such a way that plates themselves result in having the external parts of the respective wings (73) within the guide (S5), locking themselves inside the panel (5). Between the central part of the plate (7) and the bottom (52), a space is consequently formed that is intended to accommodate the free end or lower face (21 ) of the piston (2).

[0021] Preferably, the plates are glued to the panel (5) using a slow acting adhesive, such as a silicone adhesive. This is to facilitate any adjustments, during the positioning step, for the anchoring of the panels (5) to the structure

(6). The plates (7) may however also be screwed into the panel (5). Each plate

(7) has a slot with a lobe (76) of a greater diameter than the free end (21 ) of the piston (2) and a lobe (77) of a lesser diameter than the diameter of said end (21). When mounted, the plates (7) are all oriented in the same direction, i.e. with all of the respective slots (76, 77) oriented in the same direction.

[0022] According to the example shown in the accompanying drawings, the structure (6) is formed from extruded metal elements (60) that are integral therebetween in order to form a frame that is suitable for being secured to a structure to be cladded. The structure to be cladded may, for example, be a horizontal structure or a vertical structure, such as a ceiling or a wall of a cabin or other compartment of a boat. It is understood, however, that the anchoring system according to the present invention can likewise be used for covering the ceilings or walls of domestic environments, stores, offices, etc.

[0023] Each element (60) has a rear side (61 ) and an opposite front side, wherein a longitudinal channel (62) is formed with an opening (63) that is delimited by two short wings (64) that are oriented diagonally towards the central longitudinal plane (P60) of the same element (60).

[0024] According to the present invention, one or more anchoring devices (D) can be inserted into the channel (62) of each element (60) of the structure (6). With reference to the non-limiting example shown in Fig. 14, twelve anchoring devices (D), according to the present invention, are inserted into the channel (62) of each element (60) of the structure (6). Each device (D) is inserted into the channel (63) of a respective element (60) of the structure (6) by pushing the device (D) towards the inside of the channel itself. The interference of the wings (41) of the lamina (4) with the outer side of the wings (64) of the element (60) determines the bending of the wings (41 ) inwards, thereby allowing for the passage of the tubular body (1) through the opening (63), after which the wings (41) of the lamina (4) spontaneously return to the initial open configuration thereof, leaning on the inner side of the wings (64) of the element (60) as shown, by way of example, in Fig. 7. During this step, the pistons (2) are fully inserted into the bodies (1) such that, from the lower base (10) of the latter, only the ends (21 ) with the corresponding throats (20) protrude. As illustrated in the accompanying drawings, the base (10) of the tubular body (1) abuts against the outer edge of the wings (64) when the same tubular body is inserted into the channel (62) of a respective element (60). To this end, the diameter of the base (10) of the tubular body (1 ) is greater than the width (W63) of the aforementioned opening (63). [0025] Each device (D) is anchored to a corresponding plate (7), inserting the end (21 ) of the piston (2) into the first major lobe (76) of the plate and subsequently, with a translation parallel to the panel, into the narrow lobe (77). Subsequently, the panel (5) is drawn towards the structure (6) and pushed towards the latter in such a way that the flexible wings (41) of each device (D) enter, as described above, into a respective channel (62) of the structure (6) thereby determining the attachment of the devices (D) to the structure itself (6).

[0026] In order to move a panel (5) away from the structure (6) without necessarily removing it, it is sufficient to exert a pull (however moderate and predetermined in relation to the weight of the panel) against the panel (5), for example using one or more suction cup handles, overcoming the resistance exerted by the brakes (3, 30) on the relative pistons (2) until the required distance is reached (the maximum distance of the panel 5 from the structure 6 will be determined by the maximum stroke of the piston 2). The subsequent repositioning of the panel (5) on the structure (6) is determined by a thrust in the direction opposite the previous one, and also in this case the brakes (3, 30) will result in a controlled rather than free movement of the panel (5).

[0027] To remove a panel (5) from the structure (6), it is sufficient to exert a pull (however moderate and predetermined in relation to the weight of the panel) against the panel (5), for example using one or more suction cups, overcoming the resistance exerted by the brakes (3, 30) on the relative pistons (2) up until the complete extraction of the pistons themselves, after which the panel (5) is translated parallel to itself in such a way that the free ends of the pistons (2) are in the largest lobes (76) of the respective plates (7). In this configuration, the panel (5) is uncoupled from the devices (D). The first of said movements, although resulting in the distancing of the panel (5) from the structure (6), does not result in the detachment thereof.

[0028] In practice, the detachment of the panels (5) from the structure (6) constitutes a first movement in the direction (U) orthogonal to the panels themselves, followed by a second movement in the direction (L), which is orthogonal to the first.

[0029] Figs. 15A-15B schematically illustrate the anchoring of a panel (5), namely the right panel, to the structure (6): the panel (5) whereupon the devices (D) are mounted, as described above, is pushed towards the structure (6) as indicated by the "H" arrow in Fig. 15a, resulting in the insertion of the anchoring devices (D) into the channels (62) of the structure (6) as shown in Fig. 15B.

[0030] Figs. 15C-15D illustrate the distancing (Fig. 15C) and removal (Fig. 15D) step of a panel (5), namely the right panel in the drawings, from the structure (6) without the need to remove or distance adjacent panels, leaving the anchoring devices (D) attached to the structure (6) and therefore without losing the correct positioning. The subsequent re-coupling of the panel (5) to the structure (6) is determined by movements that are opposite those for the detachment. In other words, the re-coupling of the panels (5) is determined by movements (opposite those indicated by the "U" and "L” arrows) which are orthogonal to one another.

[0031] In practice, with reference to what is exemplified in Fig. 15A-15D, the uncoupling of a panel (5) takes place in two steps: the first with a vertical movement in order to overcome the thickness of the adjacent panel; the second with a horizontal movement in order to safely uncouple the panel.

[0032] To avoid any uncontrolled sliding of the panel that is being removed, it is possible to slightly tilt the panel itself, which will thus remain suspended at the corresponding anchoring devices (D) by means of the relative plates (7) until the ends (21 ) of the pistons (2) emerge from the lobes (77) of the plates. To this end, preferably, the upper surface of the plate (7), namely the surface wherein the slot is formed with the lobes (76, 77), has a portion that includes the narrow lobe (77) which is tilted towards the respective wing (73). This can ensure even greater anchoring stability against uncontrolled sliding of the panel (5) and requires a corresponding tilting of the panel itself in order to allow for the final uncoupling from the pistons (2) whereto it is anchored.

[0033] In the example shown in Fig. 12, Fig. 13 and Fig. 14 the structure (6) is secured to an overhead ceiling (not illustrated), which, for example, could be the upper deck of a yacht or a ship, by means of rods (8) connected to the structure (6) by means of brackets (80) and anti-vibration pads (81 ), in themselves known. Represented in the drawings, for simplification, is a single rod (8).

[0034] In the example of Figs. Figs. 16A-16B, the structure (6) is a vertical structure and the panel (5) is vertically anchored to the structure (6). In this case, during the step of approaching the structure (6) the panel is subjected to lifting, as in the previous case.

[0035] From the foregoing description it is evident that the anchoring device (D) according to the present invention is a device comprising a tubular body

(1 ) whereinto a braked piston (2) is axially inserted, the tubular body (1 ) having a rear side (11 ) that is configured to engage with a support structure (6) and an opposing front outlet side of the piston (2), the piston (2) having an anchoring surface (20) which can be anchored to a cladding or coating surface (5) of the support structure (6).

[0036] According to the exemplary embodiment described above, the piston

(2) is engaged by means of spring plungers (3, 30) arranged and acting radially on the side (10) where it emerges from the body (1 ).

[0037] According to the exemplary embodiment described above, on the rear side of the tubular body (1 ) an elastic lamina (4) is arranged that engages with two wings (64) of an element (60) of the support structure, which is internally hollow in order to accommodate the tubular body (1 ). [0038] According to the exemplary embodiment described, said anchoring surface is defined by the annular throat (20) formed in the vicinity of the free end (21) of the piston (2).

[0039] According to the exemplary embodiment described, the plates (7) are elements for interfacing the pistons (2) with the panels (5).

[0040] A further object of the present invention is a system for anchoring panels and similar covering or cladding elements (5) to relative support structures (6), comprising:

- a plurality of anchoring devices (D) comprising a fixed body (1 ) and a piston (2) mounted sliding in relation to the fixed body (1) and braked by braking means arranged and acting between the fixed body (1) and the piston (2), the fixed body (1) having a rear side (11) configured to engage with a support structure (6) and an opposing front emerging end of the piston (2), the piston (2) having an anchoring surface (20) which can be anchored to a cladding panel (5);

- a support structure (6) consisting of elements (60) wherein preferably channel-shaped recesses are formed that are configured such as to constitute positioning seats for the anchoring devices (D);

- multiple panels (5) provided with seats configured to receive and engage with the anchoring surfaces (20) of the pistons (2).

[0041] The system in question can be physically implemented by means of a kit of components each comprising a predetermined number of anchoring devices (D) according to the present invention and a panel (5) whereinto a predetermined number of plates is inserted (7). Preferably, a kit according to the present invention also comprises a structure (6) that is intended to be covered by the panel (5) and suitable for receiving the anchoring devices (D). The kit of pre-assembled components can thus be transported to the building site, thereby simplifying and speeding up those operations relating to the implementation of the required covering.

[0042] Although in the example described above the anchoring devices comprise a tubular body (1) with an internal piston (2), more generally, an anchoring device that can be used to implement a system according to the present invention has a fixed body (1) and a piston (2) mounted sliding in relation to the body (1 ) and braked by braking means and acting between the fixed body (1 ) and the piston (2), the fixed body (1 ) having a rear side (11) configured such as to engage with a support structure (6) by means of an elastic surface formed on said rear side (11 ) that avoids the use of screws and similar connecting members, and an opposing front emerging end of the piston (2), the piston (2) having an anchoring surface (20) which can be anchored to a cladding panel (5).

[0043] In accordance with what is described above, a system according to the present invention makes it possible to perform the following operations:

- the application of panels (5) using the anchoring devices (D) pre-mounted on the panels (5) and inserted into corresponding seats (62) arranged on the structure (6) by means of a movement (H) that is orthogonal to the panels (5) and that results in the stable insertion of the anchoring devices (D) into said seats (62);

- the detachment of the panels (5) from the structure (6) by means of a first movement in the direction (U) perpendicular to the panels themselves, followed by a second movement in the direction (L) that is orthogonal to the first;

- the distancing without detaching the panels (5) from the structure (6) by means of a movement that is orthogonal to the panels (5).

[0044] Using a device and an anchoring system, according to the present invention, an operating method can be implemented, comprising: - a step for the pre-assembly of a plurality of anchoring devices (D) entirely formed on one or more cladding panels (5) that can be associated with a structure (6) to be covered;

- a subsequent step for the insertion of said anchoring devices (D) into corresponding seats (62) of the structure (6) by means of an insertion movement (H) in a direction that is orthogonal to the panels (5) with the irreversible insertion of the anchoring devices (D) into said seats (62); and

- subsequently to said insertion step, the panels (5) can be uncoupled from the anchoring devices (D) by means of a distancing movement (U) in the direction opposite the insertion direction (H), followed by a movement (L) in a direction that is orthogonal to the distancing direction (U).

[0045] The method in question can be implemented using the anchoring system previously described which, in fact, involves the use of anchoring devices that are pre-mounted, complete, on the panels (5) - unlike traditional anchoring devices which are partially mounted on panels and partially on the structures to be covered - and that are configured in such a way as to remain associated with the structure (6) when the panels (5) are uncoupled.

[0046] According to the aforementioned operating method, panels (5) that are uncoupled from the structure (6) can be anchored again to the same structure by means of movements that are the opposite of those performed during the uncoupling step.

[0047] Consequently, the application, distancing and uncoupling operations of the panels (5) are strongly facilitated, resulting in corresponding benefits that are both economical and operational.

[0048] As previously mentioned, an anchoring system according to the present invention can be advantageously applied in the shipbuilding, civil, industrial and commercial sectors and, in general, for the cladding of both horizontal and vertical structures that can be oriented in different ways. [0049] The panels (5) can be made of any material normally used for the production of cladding panels.

[0050] With reference to Figs. 18A-21 of the attached drawings, the braking mechanism of the piston (2) provides, in place of the aforementioned radial plungers, three appendages (13) formed below the channel (C1) of the tubular body (1), inside the annular rim (10). These appendages (13) have an internal radial tooth (14) intended to interact with an annular groove (23) formed in the piston (2) at a predetermined distance from the throat (20). The pressure exerted by the appendages (13) on the annular groove (23) prevents any free movement of the piston (2). The extraction of the piston (2) is, however, permitted: pulling the piston (2) in the direction that it emerges from the body (1) results in the divergence of the appendages (13) and therefore the disengagement of the annular groove (23) on the part of the radial teeth (14). Also permitted is the re entry of the piston (2) into the channel (C1): axially pushing the piston (2) towards the rear part of the body (1 ) results in movement of the piston (2) up until the teeth (14) are repositioned within the annular groove (23). The double arrow "W’ in Fig. 19 represents the movement of appendages (13) during the movement of the piston (2). Also in this example, the tubular body (1 ) has, at the rear part thereof, two wings (41 ) forming an elastic surface with the same function as the wings (41 ) of the previously described lamina (40). The depth, or profile, of the annular groove (23) can be suitably chosen in such a way as to define a more or less pronounced interaction with the teeth (14) of the appendages (13). For example, in Fig. 20, the depth of the groove (23) is less than that of the equivalent groove of the piston in Fig. 19.

[0051] According to the example shown in Figs. 18-21 , the tubular body (1 ), in the entirety thereof, and the piston (2) can also be made from a plastic material, for example for the anchoring of lighter panels (5) and/or where fire resistance is not required. [0052] - Figs. 22A-22B are similar to Figs. 15A-15D but refer to the use of the anchoring device shown in Figs. 18A-18B. The sequence for anchoring the panels (5) to the structure (6) and for respectively detaching the panels is the same; the description thereof shall therefore not be repeated. Also in this case, as with the previously described example, the insertion of the body (1 ) into the seat (62) of the structure (6), whilst offering the possibility of practically unlimited adjustments in position, results in particularly strong coupling, given the interference of the wings (41 ) of the body (1 ) with the wings (64) of the seat (2). The anchoring devices therefore remain within the seat (62) thereof, even when the panel (5) is uncoupled.

[0053] For example, the implementation of cladding by means of a device and a system according to the present invention may anticipate the following operational steps:

- surveying the geometry of the environment to be covered, by means of a laser scanner;

- outlining a project based upon the surveys carried out;

- dimensioning and geometrical configuration of the structure (6) and the anti vibration supports (80, 81 );

- implementing the structure (6) and the panels (5);

- assembling the structure (6) within the target environment using the relative panels (5);

- any possible re-alignment of the panels (5) that may be required;

- uncoupling the panels (5) from the structure (6) for painting;

- painting the panels (5);

- final assembly of the panels (5) on the structure (6).

[0054] In practice, the execution details may vary in an equivalent manner with respect to the individual elements described and illustrated, without departing from the idea of the solution adopted and therefore remaining within the limits of the protection granted by this patent, according to the following claims.
