Description

COVER DEVICE Scope of application

The present invention relates to a covering device.

The covering device in question is intended to be used to cover exterior surfaces, protecting them from the elements, particularly from the sun and rain.

The covering device in question is suitable for the construction of pergolas, verandas and, more generally, covering structures, both in the gardens of private homes and in public outdoor spaces, such as restaurants, hotels, seaside resorts or other establishments.

The covering device which is the subject of the present invention therefore falls within the industrial sector of the production of blinds and pergolas for covering outdoor environments.

State of the art

There are many types of outdoor blinds on the market equipped with a canopy support structure, comprising four corner columns, the lower surface of which rests on the ground, connected to each other at the top by four beams arranged two by two in parallel and between which are suspended means for protecting a surface of the ground below from the sun and/or rain. For example, said covering means are composed of a flexible canvas or several tilting slats.

The covering device also includes two gutters fixed to the respective side members and placed at the respective lateral ends of the canvas or slats, in order to collect the water that flows from them when it rains.

In particular, each gutter is provided with an internal edge located under the covering means and an external edge fixed to the beams.

Typically, gutters are designed to carry water collected in columns, which therefore have a top opening at the end of the gutter to allow the water to flow out.

Furthermore, the interior of the columns has a vertical conduit designed to convey water from the gutter to the ground and to evacuate it, in particular, through a lower opening in the column, made at or near the base of the covering device.

In general, the roofing system is designed to take into account, from the outset, the assembly and positioning of the gutters and columns. In particular, not all columns require the vertical conduit to be installed inside them and the upper and lower openings to be provided to allow water to drain.

The classic device briefly mentioned above has proven, in practice, not without drawbacks.

A first disadvantage of this cover device is that it requires a complex design that must take into account, a priori, the places (in particular at the level of the columns) where it is desirable for the water to flow. Consequently, the cover devices cannot be designed and produced substantially in series, each requiring corresponding structural modifications depending on the presence or need for water flow or evacuation.

Another disadvantage is that, due to the structural modifications that need to be made, although minor, conventional roofing devices are more expensive to carry out.

Another disadvantage is that the choice of locations and columns with an evacuation must be communicated by the customer before the industrial production of the device and any subsequent modification intended to rectify the evacuation point, in the event of an error, is not easy to carry out.

Another disadvantage is that the water flow path, once designed and built, cannot be changed and, therefore, if one of the gutters or vertical pipes becomes clogged and water accumulates on the roofing device, it must be removed manually. In such cases, maintenance of the roofing device is therefore more complex.

Description of the invention

In this context, the problem underlying the present invention is therefore to eliminate the drawbacks of the aforementioned conventional solutions, by providing a simple and inexpensive covering device to manufacture.

Another objective of the present invention is to provide a covering device which does not require any particular structural modifications, in particular for the rainwater drainage system, with, in particular, the possibility of following the desired configuration even during installation and not from the time of ordering.

Another object of the present invention is to provide a cover device enabling any errors made in the design of the water flow system to be easily rectified during assembly.

Another object of the present invention is to provide a cover device allowing different configurations of water flow paths to be provided simply and quickly.

Another object of the present invention is to provide a covering device which is easy and quick to maintain.

These objectives of the present invention can be achieved by means of a covering device comprising: at least one column, which extends vertically between a lower end, intended to be placed on the ground, and an upper end, and is equipped with an internal conduit which extends between an inlet, located at the upper end, and an outlet, located at the lower end; an upper frame, which is mounted at least on the upper end of the at least one column and comprises a perimeter frame which delimits an upper opening intended to be arranged above a ground surface; covering means mounted on the upper frame and intended to close the upper opening to protect the ground surface. The upper frame comprises at least one gutter arranged along at least a portion of the perimeter frame, at least partially below the covering means to collect water coming from the covering means; the gutter is adapted to be connected to the internal conduit of the at least one column by means of the corresponding inlet orifice to allow water to exit the gutter. The cover device comprises at least one closing element configured to be arranged, in a removable manner, in order to hermetically close the inlet orifice of the internal conduit of the at least one column to prevent the flow of water from the gutter to the at least one column.

According to another particular characteristic of the invention, the closing element is configured to be applied by screwing in order to close the inlet orifice.

According to another particular feature of the invention, the cover device comprises at least one fixing element, which is fixed to the upper end of the corresponding column, connects the liquid to the gutter and is provided with a passage hole connected to the inlet port; the closing element is configured to be removably engaged (or fixed) to the passage hole of the fixing element.

According to another particular characteristic of the invention, the closing element is provided with an engagement portion, intended to be engaged to the passage hole, and a gripping portion, intended to be grasped by a user to apply the closing element to the passage hole.

According to another particular characteristic of the invention, the fixing element comprises a bottom wall where the passage hole is located, and the closing element comprises a stop part projecting radially relative to the engagement part and located in abutment on the bottom wall around the passage hole when the engagement part is inserted into said passage hole.

Detailed description of a preferred embodiment example

With reference to the attached drawings, in particular to the , the covering device, as a whole, which is the subject of the present invention, is indicated by 1.

The covering device 1 in question is suitable for the construction of pergolas, verandas and, more generally, structures for covering external environments, such as gardens of private homes and public outdoor spaces, such as restaurants, hotels, seaside resorts, etc.

According to the embodiment illustrated in the accompanying drawings, the covering device 1 which is the subject of the present invention comprises at least one column 2, which deploys vertically between a lower end 21, intended to be placed on the ground, and an upper end 22, and is equipped with an internal conduit 23, which deploys between an inlet orifice 24, located at the upper end 22, and an outlet orifice 25, located at the lower end 21. In particular, the column deploys in a vertical deployment direction Z between the lower end 21 and the upper end 22.

Advantageously, the covering device 1 comprises at least two columns 2.

Naturally, without departing from the scope of the present invention, the column 2 can be placed on the ground directly, or indirectly, for example by fixing it to a platform or a low wall.

Furthermore, the expression “at the level of”, which refers in particular to the lower end 21 of the column 2, may be understood as meaning that the outlet orifice 25 is adjacent to the lower end 21, or else placed close to the latter but deviating vertically by a few decimeters, for example.

More precisely, each column 2 comprises an elongated body 26 formed from a single piece and extending longitudinally between the lower end 21 and the upper end 22, in the vertical deployment direction Z.

Advantageously, the elongated body 26 of each column 2 has a substantially quadrangular section (for example, square or rectangular) defining four sides of the corresponding column 2, arranged around the vertical deployment direction Z.

In particular, the elongated body 26 is made of a metallic material and is obtained, for example, by extrusion.

In addition, the column 2 advantageously comprises a flow conduit 27, which extends from the inlet orifice 24 to the outlet orifice 25, in particular inside the elongated body 26 of the column 2. In particular, the flow conduit 27 is configured to convey the water entering through the inlet orifice 24 to the outside of the column 2. Advantageously, inside the flow conduit 27 is the internal channel 23.

Naturally, without departing from the scope of the invention, the column 2 may not include the flow conduit 27 and, in this case, the internal channel 23 is directly determined by the elongated body 26 of the column 2.

The covering device 1 also comprises an upper frame 3, which is mounted at least on the upper end 22 of the column 2 and comprises a perimeter frame 31 which delimits an upper opening intended to be arranged above a ground surface. Advantageously, the upper frame 3 forms an essentially horizontal plane parallel to the ground.

According to an alternative embodiment, the upper frame 3 forms an inclined or tilting plane relative to the ground.

According to a non-limiting exemplary embodiment, the upper frame 3 of the covering device 1 comprises two side beams 32 parallel to each other and juxtaposed. In addition, the upper frame 3 of the covering device 1 also preferably comprises two front beams 33 parallel to each other and juxtaposed, connecting to the side beams 32. In particular, the side beams 32 and the front beams 33 form the upper frame 31 advantageously quadrangular.

More precisely, each side beam 32 deploys longitudinally, advantageously between a head portion 32’ and a bottom portion 32’’, along a first corresponding deployment direction X, preferably substantially horizontal, and each front beam 33 deploys advantageously in the longitudinal direction, along a second corresponding deployment direction Y, substantially orthogonal to the deployment directions X of the side beams 32.

In particular, one of the two front beams 33 connects to the head portions 32' of the side beams 32, and the other front beam 33 connects to the bottom portions 32'' of the side beams 32.

Advantageously, each beam 32 and 33 of the upper frame 3 comprises respectively a first and a second elongated profile 34 and 35, each being obtained, preferably, from an extrusion of metal, in particular aluminum.

If two or more columns 2 are present, the upper frame 3 is advantageously mounted on the upper ends 22 of said columns 2.

Advantageously, the columns 2 which support the upper frame 3 comprise two first columns 2’ placed on the ground, each of which advantageously supports the head part 32’’ of the corresponding side beam 32.

The columns 2 which support the upper frame 3 also preferably comprise two second columns 2’’ supporting the bottom parts 32’’ of the corresponding side beams 32, thus creating a self-supporting structure, in particular having a substantially parallelepiped shape.

Alternatively, in accordance with a different embodiment not illustrated in the accompanying drawings, the covering device 1 is attached to a vertical wall (for example, the wall of a building) to which the head parts 32' or the bottom parts 32'' of the side beams 32 are fixed. In this case, the columns 2 advantageously comprise only the first columns 2'.

Alternatively, in accordance with another exemplary embodiment not illustrated in the accompanying drawings, the covering device 1 is leaning against two vertical walls (for example, the wall of a building) forming an angle between them, in particular orthogonally. In this case, the head parts 32' or the bottom parts 32'' of the side beams 32 are fixed to one of these vertical walls, while an entire side beam 32 is fixed to the other laterally. In this case, the covering device 1 advantageously comprises only one column 2, or only a first column 2'.

According to another different example of embodiment not illustrated in the attached drawings, the covering device 1 comprises several juxtaposed covering modules, which comprise columns 2 in common with each other.

Advantageously, said side beams 32 and front beams 33 of the perimeter frame 31 delimit between them the upper opening, located above the ground surface intended to be protected by the covering device 1.

The covering device 1 also comprises covering means 4, mounted on the upper frame 3 and intended to close the upper opening to protect the ground surface.

In particular, the covering means 4 are movable, thus passing from a closed configuration, in which they close the upper opening to protect the ground surface, to at least one open configuration, in which they free, at least partially, the upper opening to let light pass through.

Naturally, without departing from the scope of the present invention, the covering means 4 can be fixed in a closed, open or semi-open configuration.

According to the embodiment illustrated in the accompanying drawings, the covering means 4 comprise a plurality of covering blades 41 placed one after the other, in particular in the first direction of deployment X of the side beams 32, preferably from the head parts 32' to the bottom parts 32'' of the side beams 32, and which can advantageously be actuated to close said upper opening in order to cover the ground surface located below to protect it from the sun and/or rain.

According to a different embodiment not illustrated, the covering means 4 comprise a retractable or foldable covering canvas, slidably mounted on the perimeter frame 31, preferably on the side beams 32.

Advantageously, in both embodiments, the covering means 4 and their actuation means are of the conventional type and will therefore not be described further below.

The upper frame 3 of the covering device 1 comprises at least one gutter 30 located along at least one portion 32, 33 of the perimeter frame 31 at least partially under the covering means 4 to collect rainwater coming from these same covering means 4. In particular, the gutter can be connected to the internal conduit 23 of the column 2 by the corresponding inlet orifice 24 to drain the water from the gutter 30.

Hereinafter, the portion of the perimeter frame 31 will be formed, for example, by a side beam 32, a front beam 33 or a portion thereof.

If two or more columns 2 are present, the gutter 30 can be connected to the internal conduits 23 of said columns 2 by the corresponding inlet ports 24 to drain the water from the gutter 30.

The covering device 1 preferably comprises several gutters 30, each being associated with a different part 32,33 of the perimeter frame 31, and preferably comprises a corresponding gutter 30 for each side beam 32 and/or for each front beam 33.

Naturally, without departing from the scope of the present invention, the covering device 1 may also comprise a single gutter 30, for example being associated with the front beam 33 and designed to collect water coming from the covering means 4. In this case, to improve the flow of water towards this gutter 30, the upper frame 3, and therefore the covering means 4 mounted thereon (for example, a retractable canvas), may be inclined, with the front beam 33 arranged at a height from the ground lower than the remaining part of the upper frame 3.

More specifically, the gutter 30 comprises a shaped profile made of metallic material, obtained, for example, by extrusion.

Advantageously, each gutter 30 is provided with two side walls 30', preferably parallel to each other, and a lower wall 30'' for the lower connection of the two side walls 30', as shown, for example, in .

According to the basic idea of the present invention, the cover device 1 comprises at least one closing element 5 configured to be arranged, in a removable manner, in order to hermetically close the inlet orifice 24 of the internal conduit 23 of the column 2 to prevent the flow of water from the gutter 30 to the column 2.

If at least two columns are present, at least one of said closing elements 5 is advantageously configured to be arranged so as to close the inlet orifice 24 of the internal conduit 23 of at least one of said columns 2.

In this way, the columns 2 can advantageously all be made identically, without having to design them differently and foresee in advance in which column(s) to envisage the flow of rainwater. Consequently, this closing element 5 makes it possible to decide directly at the time of installation which inlet orifice 24 of the internal conduit 23 to selectively close and which orifice to keep open to allow the flow of water, thus obtaining a much more versatile cover device 1, which can therefore be installed in different environments with fewer structural modifications.

Advantageously, it is also possible to modify the rainwater flow path after installation of the cover device, by selectively opening and/or closing the appropriate inlet ports 24 of the columns 2 or by means of the closing element 5.

Optionally, the cover device provides a closing element 5 for each column 2, which can be associated with the corresponding inlet port 24.

For example, the cover device 1 comprises at least two closing elements 5, each of which can be associated with a respective column 2 to close the inlet orifice 24 of the corresponding internal conduit 23.

Advantageously, the closing element 5 is configured to be applied by screwing in order to close said inlet orifice 24.

Furthermore, the closing element 5 is advantageously in the form of a cap, preferably a profiled screw cap.

Naturally, without departing from the scope of the present invention, the closing element 5 can be produced in another way, for example in the form of a trapdoor or a valve.

According to the preferred embodiment of the present invention, the cover device 1 comprises at least one fixing element 6, each of which is fixed to the upper end 22 of the corresponding column 2, connecting the liquid to the gutter 30 and provided with a passage hole 61 communicating with the inlet orifice 24. In particular, the closing element 5 is configured to be removably engaged to the passage hole 61 of the fixing element 6.

If two or more columns 2 are present, the cover device 1 advantageously comprises at least two fixing elements 6, each of which is fixed to the upper end 22 of the corresponding column 2, connecting the liquid to the gutter 30 and provided with a passage hole 61 communicating with the inlet orifice 24. In this case also, the closing element 5 is advantageously configured to be removably engaged to the passage hole 61 of the fixing element 6.

More specifically, the closure element 5 is provided with an engagement portion 51, intended to be engaged to the through hole 61, and a gripping portion 52, intended to be grasped by a user to apply the closure element 5 to the through hole 61. In particular, the gripping portion 52 may have a shape allowing the user to grasp it directly or have shaped recesses allowing it to be grasped by suitable tools.

Advantageously, the engagement part 51 of the closing element 5 is provided with a thread 510 and the passage hole 61 of said fixing element is provided with a counter-threaded part 610, intended to be engaged by screwing to the engagement part 51.

In addition, the fixing element 6 advantageously comprises a bottom wall 62 where the passage hole 61 is located. In addition, the closing element 5 advantageously comprises a stop portion 53 projecting radially relative to the engagement portion 51 and located in abutment on the bottom wall 62 around the passage hole 61 when the engagement portion 51 is inserted into the passage hole 61.

In accordance with the embodiment illustrated in the accompanying drawings, and in particular in the , the through hole 61 is hydraulically connected to the flow conduit 27 of the column 2 and, preferably, the flow conduit 27 is fixed to the fixing element 6 at the through hole 61, so that water is conveyed therein when the through hole 61 is open.

In order to improve the sealing of the closure of the inlet orifice 24, the cover device 1 advantageously comprises sealing means 7 interposed between the closure element 5 and the inlet orifice 24 closed by the closure element 5.

In particular, the sealing means 7 are interposed between the bottom wall 62 of the fixing element 6 and the stop part 53 of the closing element 5 applied to the passage hole 61.

More specifically, the sealing means 7 comprise an annular seal 71 placed around the passage hole 61, at least when the closing element 5 is applied to the passage hole 61.

According to a first variant embodiment illustrated in the attached drawings, the bottom wall 62 of the fixing element 6 comprises an annular groove 63 placed around the passage hole 61. Advantageously, the annular seal 71 is housed in the annular groove 63.

According to a second variant embodiment not illustrated, the annular seal 63 is associated, preferably fixed, with the closing element 5 and in particular with the stop part 53.

Naturally, without departing from the scope of the present invention, the annular groove 63 can also be present in the second embodiment variant. Furthermore, in both variants, this annular groove can be produced only on the fixing element 6, as indicated above, or just on the closing element 5, in particular on the stop part 53 of the latter, or on both the fixing element 6 and the closing element 5.

As shown in Figures 3 and 4, the fixing element advantageously comprises a circulation collector 64 provided with at least one access opening 65, by which the circulation collector 64 is connected to the gutter 30, and connected, by the passage hole 61, to the inlet orifice 24 of the internal conduit of the column 2.

According to the preferred embodiment of the present invention illustrated in the accompanying drawings, the perimeter frame 31 comprises two adjacent parts 32, 33, connected at an angle at a connection zone 310 located at the upper end 22 of the corresponding column 2.

In addition, the upper frame 3 advantageously comprises at least two adjacent gutters 30 placed along the corresponding adjacent parts 32, 33 and connected to each other at the connection zone 310. In particular, the closing element 5 is configured to be applied in the connection zone 310.

In particular, the fixing element 6 is placed in the connection zone 310 to connect the adjacent gutters 30.

Advantageously, the circulation collector 64 of the fixing element 6 comprises two access openings 65, each being connected to one of the corresponding adjacent gutters 30.

In order to easily connect the column 2 and/or the fixing element 6 to the gutters 30, the covering device 1 comprises a connecting element 8, which is fixed at the upper end 22 of the column 2, in particular its elongated body 26, and is provided with a central plate 80 and several engagement elements 81, each extending from the central plate 80 and being fixed to a gutter 30.

In particular, the connecting body 8 (preferably its central plate 80) is interposed between the upper end 22 of the column 2 and the fixing element 6.

As shown in the , the connecting body 8 comprises at least one pair of these engagement elements 81 fixed to a gutter 30.

More specifically, the engagement elements 81 are fixed to the lower wall 30’’ of the gutter 30 and are in particular inserted into an engagement location situated in the lower wall 30’’ of the gutter 30.

Advantageously, each engagement element 8 of the connection body 8 comprises a connection socket 82 inserted into the corresponding engagement location of the corresponding gutter 30.

Advantageously, the connecting body 8 is provided with two pairs of engagement elements 81, arranged orthogonally to each other. Each of these pairs of engagement elements 81 is fixed to one of the corresponding gutters 30, adjacent to the connecting zone 310. Each pair of engagement elements 81 is preferably placed at the corresponding side of the column 2.

Advantageously, the connecting body 8 is in the form of a plate. In particular, the connecting body 8 is made in a single piece, preferably of metallic material, and is obtained, for example, by molding or by cutting.

The connecting body 8 is preferably fixed to the upper end 22 of the elongated body 26 of the corresponding column 2 by means of first fixing screws 83 preferably inserted into first through holes of the connecting body 8 and screwed into corresponding first fixing holes of the elongated body 26.
