Description

AREA OF APPLICATION The present invention relates to a roofing device equipped with roofing elements that are movable from a roofed position to an open position, an uncovered position, and vice versa. The roofing device according to the present invention can preferably, but not exclusively, be a pergola, a sunshade, or the like, even in large dimensions, on the order of several meters on each side. The movable roofing elements are designed such that they selectively form a roof over an area below, protecting it from weather conditions such as sun, rain, snow, or hail, as well as from other potentially falling objects such as branches, leaves, dirt, or the like. STATE OF THE ART Various types of roofing devices are known, such as pergolas or adjustable sunshades, which use elongated roofing elements and have the function of optionally or temporarily protecting an area underneath from both sun rays and atmospheric precipitation such as rain or snow. In general, a roofing device of a known type comprises a surrounding supporting structure that defines a type of frame of rectangular or square shape, designed to be positioned at a certain height from a support base. This supporting structure typically comprises a pair of lateral crossbeams that serve as supports for the roofing elements, and a pair of beams, a front and a rear beam, arranged perpendicular to the lateral crossbeams. The lateral crossbeams define a longitudinal direction along which the roofing elements can move. The roofing elements are parallel to each other and connected at their ends to an execution mechanism designed to allow them to optionally assume a roofing position in which they are coplanar with a roofing plane and protect the area below, as well as an open position or cover position in which they are inclined by several degrees, for example up to 90°, relative to the aforementioned roofing plane and are arranged towards the end beam of the supporting structure. Furthermore, the roofing elements are generally all identical, meaning they have a specific width. Width is defined as their dimension parallel to the aforementioned longitudinal direction when installed in the supporting structure. Additionally, the roofing elements are arranged so that, when closed, each one is spaced a specific, fixed distance from its neighbor. Examples of such roofing devices are described in EP 3 059 355 and WO 2020 / 121357. One of the disadvantages of current roofing devices is that the internal length of the supporting structure, defined by the distance between the two end beams, must always be an integer multiple of the width of each roofing element or the aforementioned fixed distance. Otherwise, the total extent of the closing elements in the roofed position is smaller than the area to be protected underneath. Furthermore, a water drainage element, which serves as a rain gutter, is usually installed in conjunction with the end beam on the inside of the frame as defined by the supporting structure. The known solutions for overcoming this problem involve positioning a fixed protective element, consisting of a sheet of metal of standardized dimensions, which is attached to the supporting structure at the height of the end beam, possibly above the aforementioned water drainage element. These known solutions, however, require the sheet metal to be adjusted from time to time to compensate for the missing dimension. Furthermore, if the sheet metal is not cut precisely, this can lead to coupling problems with the roofing element closest to the end beam, resulting in excessive overlaps or cracks. Furthermore, some of these known solutions are still not compatible with the rotational and sliding movement that is characteristic of the roofing elements of at least some known devices. In any case, if the positioning of a fixed sheet metal near the head beam is planned, the problem of water drainage remains, which arises, for example, from rain or loose snow that falls into the space below when the roofing elements are partially opened, instead of draining away properly. The roofing device according to application EP 3 059 355 has a front and / or end beam equipped with special channels for the flow of pressurized warm air, so that the warm air flow is directed longitudinally onto the top and bottom of the louvers to shorten the thawing time of snow, hail, or ice that has accumulated on the louvers in the roofing position. The beam thus shaped does not interact with the louvers to compensate for non-standard dimensions of the structure, nor does it allow water to run off. The roofing device according to WO 2020 / 121357 shows only standard solutions where the internal length of the support structure is an integer multiple of the width of each of the roofing elements. Therefore, there is a need to create a roof that can eliminate at least one of the disadvantages of the current state of the art. One purpose of the present invention is to provide a roofing device with movable roofing elements, wherein any gap that may arise between an end element of the roofing and an end beam of a supporting structure when the movable roofing elements are in a roofing position is stably and safely covered without causing impairments or other problems in the movement of the movable roofing elements. Another purpose of the present invention is to provide a roofing device with movable roofing elements, ensuring proper drainage of rainwater or other weather influences that might penetrate into the possible free space between the end element of the roofing and the end beam, even if an end element of the roofing does not perfectly abut an end beam of a supporting structure when the movable roofing elements are in a roofing position. In order to eliminate the disadvantages of the prior art and to achieve these and other objectives and gain advantages, the applicant has developed, tested and created this invention.

The dependent claims set out further features of this invention or embodiments of the main concept. In accordance with the aforementioned purposes, a roofing device according to the present invention comprises a pair of lateral crossbeams arranged perpendicular to at least one end beam, and a plurality of transverse elements of the roofing which are mounted on the movable lateral crossbeams in a manner that allows them to be displaced at least between an open position and a roofing position in which they are arranged substantially on a roofing plane.

DESCRIPTION OF SOME EXECUTION FORMS With reference to Fig. 1, a roofing device 100 according to the present invention comprises a roofing frame 110 with a pair of lateral crossbeams 113, 114 and a pair of end beams 115, 116, which are connected to each other in such a way that they form a substantially square or rectangular structure which limits the area to be roofed above. The device 100 comprises a plurality of transverse elements of the roof 111, which are movable along a longitudinal direction Z in forward / backward movement from a roof position to an open position and vice versa. Each transverse element of the roof 111 is spaced from the adjacent transverse element of the roof 111 at a specific distance PE. The lateral crossbeams 113, 114 are arranged essentially parallel to each other and to the longitudinal direction Z, while the end beams 115, 116 are arranged essentially parallel to each other and orthogonal to the longitudinal direction Z. The transverse elements of the roof 111 are connected at their ends, for example by special guides, to the lateral crossbeams 113, 114 in a way that allows them to be moved. The movement of the transverse elements of the roof 111 can follow a rotational and translational movement path, whereby each transverse element of the roof 111 can rotate in a coordinated manner around its own axis of rotation and simultaneously be translated in a combined manner along the longitudinal direction Z. This type of movement provides that the transverse elements of the roof 111 move together in the longitudinal direction Z in both directions between the open position (not shown), in which the transverse elements of the roof 111 are arranged towards the end beam 116 and take up only minimal space, and the roof position, in which the transverse elements of the roof 111 form a roof plane PC with their undersides. The end beams 115, 116 run parallel to the arrangement of the transverse elements of the roof 111, perpendicular to the longitudinal direction Z, and the distance D between the end beam 115 and one of the last of the transverse elements of the roof 111A, measured along the longitudinal direction Z when the plurality of transverse elements of the roof 111 is in the roof position, is less than the distance PE. In other words, the internal distance between the two end beams 115, 116 differs from the distance PE by a multiple. This can be the case if custom dimensions of the roof frame 110 are required. When the transverse elements of the roof 111 are moved in combination, the reference end beam 115 is the one to which the transverse elements of the roof 111 are moved in order to reach the roof position. The device 100 further comprises a water drainage element comprising or consisting of an end channel 117 connected to the end beam 115, which is arranged parallel to it to receive and enable the water drainage. The device 100 comprises a compensating device 10 with a width L, in a direction parallel to the longitudinal direction Z, smaller than the aforementioned distance PE and in use on the lateral crossbeams 113, 114 close together or in contact, or continuously with the end beam 115, cooperating with the last of the transverse elements of the roof 111A and with the end gutter 117 and / or with the end beam 115, in order to ensure proper water drainage and to completely or partially cover the space between the end beam 115 and the last of the transverse elements 111A when the plurality of transverse elements of the roof 111 is in the roofing position. The compensating device has at least one part that is substantially coplanar with the roofing plane PC in order to fully or partially cover the space corresponding to the distance D and to interact with the last transverse element 111A when the transverse elements of the roofing 111 are in the roofing position. In particular, the compensating device 10 has a lower part that is at least partially coplanar with the roofing plane PC and an opposing upper part that is designed to cooperate at least partially with the last of the transverse elements 111A to ensure proper water drainage. It should be noted that the interaction between the last of the transverse elements 111A and the end beam 115 can take various forms. For example, the last of the transverse elements 111A can project beyond the compensating device 10 with or without mutual contact, as explained in more detail below, or an "interface" or overlap between the two components can be provided. Other solutions are also possible. This space is characterized by the aforementioned distance D, which can lie between a value of approximately 0.1 times the distance PE and a value below the distance PE, advantageously approximately the distance PE. Furthermore, the mutual position of the compensating device 10 and the last of the transverse elements of the roof 111A in the roof position is precise and defined and independent of the aforementioned distance D. The attachment of the compensating device 10 to the lateral crossbeams 113, 114 in a precise and defined position relative to the last of the transverse elements of the roof 111A, and the combination or overlap of its space requirement with that of the end gutter 117 parallel to the longitudinal direction Z, means that the dimensions of the compensating device 10 are independent of the aforementioned distance D. In this way, the compensating device 10 can always be mounted without the need for customer-specific modifications or adjustments. According to an embodiment shown in Fig. 9, the compensating device 10 can be connected directly or indirectly to one of the end beams 115, 116, in particular the reference end beam 115. In the latter case, an intermediate support element 124, for example a sheet metal profile attached to the end beam 115, 116, can be provided, and the compensating device 10 can be adjustably attached to the intermediate support element, i.e., more or less overhanging, to bridge the aforementioned distance D. In this embodiment, attachment to the side beams 113, 114 may be unnecessary or advantageous to provide additional support. According to another embodiment shown in Fig. 10, the compensating device 10 can be connected directly or indirectly to the front channel 117 or the side channels. As described in more detail below, the design of the compensating device 10 is such that a planned configuration of the interaction, in particular the coupling, with the last of the transverse elements of the roof 111A, in particular with a longitudinal end of the last of the transverse elements of the roof 111A, is ensured in order to enable proper water drainage so that there is no undesirable seepage in the area below. The compensating device 10 is arranged at a medium height between the last of the transverse elements of the roof 111A and the end gutter 117, which is located at a lower height than both elements. The compensating device 10 extends at least partially beyond the end gutter 117 and is at least partially extended beyond the last of the transverse elements of the roof 111A. In other words, the last of the transverse elements of the roof 111A overlaps at least partially the compensating device 10 when the transverse elements of the roof 111 are in the roof position. This mutual arrangement enables the end channel 117 to receive the water coming from the equalizing device 10. In one possible assembly arrangement, the compensating device 10 can be located completely (Fig. 4) or mostly (Fig. 5) within the space required by the end channel 117 and in this case has only the function of ensuring proper water drainage. In total, the compensating device 10 and the end gutter 117 cover the distance D between the end beam 115 and the last of the transverse elements of the roof 111A. According to embodiments, each transverse element of the roof 111 comprises a base body 118 provided with a collection channel 119 on one side and a lateral longitudinal extension 120 on the other. The lateral longitudinal extension 120 is arranged at least partially, preferably completely, above the predominant space requirement of the base body 118 and is designed in such a way that it interacts with the collecting channel 119 of an adjacent transverse element of the roofing 111 when the transverse elements of the roofing 111 are in the roofing position. The lateral longitudinal extension 120 has an inner side wall 121 for connection with the base body 118 and an opposite outer side wall 122, which is limited by a free end edge that can, for example, serve as a reference for the positioning of the compensating device 10. Other embodiments of the transverse elements of the roof 111 are also possible. The end gutter 117 is attached to the end beam 115 in a lower position than the roofing level PC and the leveling device 10. According to embodiments, the compensating device 10 comprises a box-shaped main body 11 extending predominantly along a transverse axis X, which is bounded by two opposite ends 12, 13, at which it is attached to the lateral crossbeams 113, 114 in use. The main body 11 is arranged with the transverse axis X parallel to the longitudinal extent of the transverse elements of the roof 111 and has a length that essentially corresponds to the length of the transverse elements of the roof 111. The main body 11 is provided at the top with a collection wall 14, which has an inclined conveying section 15 and a discharge section 16 arranged next to the conveying section 15 at a level or height that is at least partially lower than this, in order to define a discharge channel 17. For example, the discharge section 16 is recessed laterally to the conveying section 15. According to an embodiment shown in Fig. 12, the conveying section 15 can be arranged horizontally. According to another embodiment, illustrated in Fig. 11, the collection wall 14 could only have the discharge section 16, whereby the conveying section 15 may not be present, or it may be considered in continuity with the discharge section 16 on the same plane. In particular with reference to Figs. 2 to 3, the drainage section 16 of the compensating device 10 is at least partially overlooked by the lateral longitudinal extension 120 of the last of the roofing elements 111A when it is in the roofing position. The overlap of the last of the roofing elements 111A on the main body 11 of the compensating device 10 is advantageously designed without mutual contact between the two components. The drainage section 16 has a design that is such that it interacts with the longitudinal end of the last of the roofing elements 111A. This design is also examined taking into account the rotational and displacement movement of the roofing elements 111. In general, the drainage section 16 has a design that essentially corresponds to that of the longitudinal end of the last of the roofing elements 111A, i.e. the lateral longitudinal extension 120. The drainage section 16 has a design that essentially corresponds to that of the lateral longitudinal extension 120. The lateral longitudinal extension 120 is arranged above the drainage section 16, in particular above the drainage channel 17, and together with it forms a labyrinth for collecting any water that may enter. The drainage channel 17 runs parallel to the transverse axis X and may or may not have a slight incline towards one of the two opposite ends 12, 13 to facilitate water drainage to the lateral gutters of the roofing structure 100. The lateral gutters may be connected to the lateral crossbeams 113, 114. The drainage channel 17 runs parallel to the lateral longitudinal extension 120 of the last of the transverse elements of the roof 111A and has essentially the same length. The main body 11 is further provided at the bottom with a bottom wall 18 opposite the collection wall 14 and laterally with a first and second side wall 19, 20 opposite each other. The compensating device 10 is arranged such that an underside of the bottom wall 18 of the main body 11 is essentially coplanar with the roofing plane PC, without any minor deviations occurring due to the mutual position of the compensating device 10 and the last transverse element of the roofing 111A to ensure proper approximation to each other. This mutual positioning allows, when the multitude of transverse elements of the roof 111 is in the roof position, a high aesthetic quality as seen from inside the roof device 100, since the roof plane PC has essentially no obvious interruptions. According to embodiments, the conveying section 15 is essentially flat along its entire length. However, it is not excluded that the conveying section 15 may also have a curved profile or include grooves transverse to the longitudinal axis X for conveying the water flow. The conveying section 15 is bounded by a first edge 21 and a second edge 22, preferably parallel to each other and to the transverse axis X. It is not excluded that these edges 21 and 22 may not be parallel to each other. The first edge 21 is at a lower height than the second edge 22, so the height difference defines the aforementioned inclination. Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 to Fig. 8, the conveying section 15 is inclined in a direction transverse to the transverse axis X in the direction of the end channel 117, see for example Fig. 3. The inclination of the conveying section 15 is defined relative to a horizontal plane, for example the ground plane, such that the water can flow away by gravity, for example within the end channel 117. The first edge 21 is located in an outer position and is situated on the first side wall 19, specifically in its upper region. The first edge 21 is the one closest to the end beam 115 and the end groove 117. The main body 11 is provided with an inner longitudinal side 23, which is arranged between the first and the second side wall 19, 20 and separates the conveying section 15 from the discharge section 16. The second edge 22 is located in an inner position and is situated on the inner longitudinal side 23, particularly in one of its upper regions. The drainage section 16 comprises the aforementioned drainage channel 17, which is bounded laterally by the second side wall 20, the inner longitudinal side 23 and at the bottom by a base wall 24. The base wall 24 is located at a higher height than the floor wall 18 and is parallel to it in the example described herein. In possible embodiments, the drainage channel 17 can be limited at the bottom by the same bottom wall 18. The inner longitudinal side 23 connects the containment wall 14 with the base wall 18 and is arranged essentially orthogonally to it. However, it may be provided that the inner longitudinal side 23 terminates at the base wall 24 and does not extend to the base wall 18. The inner longitudinal side 23 and the second side wall 20 are essentially perpendicular to the base wall 24, even though in the example described herein the second side wall 20 is slightly inclined. In particular, the compensating device 10 can be positioned in use such that the inner longitudinal side 23 is essentially aligned with the free end edge of the outer side wall 122 of the lateral longitudinal extension 120 of the last of the transverse elements of the roof 111A when the plurality of transverse elements of the roof 111 is in the closed position. This positioning enables the creation of a coupling configuration that produces the same or a similar coupling as between a transverse element of the roof 111 and the adjacent element, so that the water drainage can be effectively controlled. In the event that the conveying section 15 is not provided, Fig. 11, the second edge 22 and the inner longitudinal side 23 are not present and the discharge section 16 extends over the entire width of the compensating device 10. The main body 11 is further provided with elongated recesses 25 which are designed to receive the respective retaining means 26 which are suitable in use to interact with the last of the transverse elements of the roofing 111A, with the end gutter 117 or directly with the end beam 115. The elongated recesses 25 run parallel to the transverse axis X along the entire length of the main body 11. The retaining means 26 can be, for example, seals, rubber or PVC lamellae, damping brushes or other similar or comparable means. The retaining means 26 can be arranged on the edges of the drain section 16, see Fig. 6, so that they interact with the last of the transverse elements of the roof 111A visible in Fig. 3. According to the embodiments described herein, the main body 11 is formed in a single body, for example by extrusion. However, it is not excluded that the main body 11 may be formed with separate elements or components that are optionally coupled by means of known systems. The compensating device 10 comprises a pair of brackets 27, 28 which can be connected to the ends 12, 13 of the main body 11 and are designed to allow the compensating device 10 to be attached to the roofing frame 110, in particular to the lateral crossbeams 113, 114. With reference to Fig. 6, Fig. 7 to Fig. 8, each bracket 27, 28 has a first coupling wall 29 for attachment to the main body 11, a second coupling wall 30 for attachment of the compensating device 10 to an inner side surface of the lateral crossbeams 113, 114 and a support wall 31 arranged transversely between them and designed to support the compensating device 10. The first coupling wall 29 runs parallel to the second coupling wall 30, while the retaining wall 31 is arranged orthogonally between them to define an essentially stepped design. The coupling wall 29 has an opening 32 at the end of the drain channel 17 and further openings 33 that are in contact with the interior of the main body 11. In use, the openings 32 and 33 allow water to drain outwards from the main body 11, for example to the side channels. The second coupling wall 30 has at least one elongated hole 34, in this case two elongated holes 34, designed to accommodate one or more fastening means such as a screw, a rivet, a nail or similar or comparable fastening means. In accordance with the embodiments shown in Fig. 6, Fig. 7 to Fig. 8, the elongated holes 34 have a predominant extent along a respective development axis to which they run parallel to each other. It is also possible that the elongated holes 34 are not parallel to each other, for example to allow for better adjustment when installing the compensating device 10. For example, the elongated holes 34 can be inclined relative to each other. The second coupling wall 30 has reference means on an upper edge 35, for example a reference mark 36, which is designed to enable the installer to properly attach the compensating device 10 to the roofing device 100. The reference mark 36 can be used to determine the proper installation position of the compensating device 10 in relation to the last of the transverse elements of the canopy 111A. For example, the reference mark 36 can be aligned with the free end edge of the outer side wall 122 of the lateral longitudinal extension 120 of the last of the transverse elements of the canopy 111A when the plurality of transverse elements of the canopy 111 is in the canopy position. The roofing device 100 described herein is further provided with a lower supporting structure 123 comprising four vertical posts that support the roofing frame 110. Of course, 100 changes can be made to the roofing device described so far and / or parts can be added without deviating from the invention concept defined in the patent claims.
