Title.
Folding protection cover Object of the invention.
The object of the present invention is a folding protection cover, intended to be positioned on a surface to be protected from atmospheric phenomena, for example rain, hail or frost. Field of application of the invention.
This invention is applicable in the agricultural sector for the protection of crops and fruit trees, in parking lots of vehicles and in general on any surface to be protected from atmospheric phenomena. State of the art
The use of crop protection devices against certain atmospheric phenomena that can damage crops is currently known, for example, the hail protection networks that are mounted on cables fixed to rows of support posts are known.
Depending on the type of protection to be achieved, the surface of the roof will consist of a flexible sheet that can be, for example, a net against hail, a shade mesh, or a waterproof sheet.
In the agricultural sector, these protective covers may have a length of 200 or 300 meters, the roof surface being formed with long strip strips, oriented in the same direction as the rows of posts.
In the existing protective covers said strip of sheets can be folded and


deploy laterally, that is, in a direction perpendicular to the rows of posts in order to open and close the roof.
This folding and unfolding is done manually and, given the length of the roof, this operation can be laborious and require significant time.
Some crops require for a correct ripening of the fruits that the cover is kept open in order to keep them exposed to sunlight; However, it is important that they are not exposed to rain or hail before collection, as this can spoil the entire crop.
For the reasons stated above, the folding protection covers currently available do not allow the folding or unfolding of the cover quickly and easily and close said cover in the event of a storm approaching.
Therefore, the technical problem that arises is the development of a folding protection cover that allows the opening and closing of the same to be carried out quickly and easily. Description of the invention
The folding protection cover, object of this invention, is of the type comprising: longitudinal rows of posts arranged in parallel, fixed cables arranged parallel to the rows of posts, and at least one flexible protective sheet forming a cover surface.
To achieve the proposed objectives, this folding protection cover comprises a series of sections of protective foil, approximately of the same length, aligned in a longitudinal direction parallel to the fixed cables, each section of foil presenting a first end fixed to the longitudinal cables fixed; and a second end fixed to mobile cables.
These mobile cables are arranged parallel to the fixed cables; and set by


the ends opposite to simultaneous winding and unwinding means that move said moving cables at a distance approximately equal to the length of a section of protective sheet; displacing them between: a closed position of the roof, in which all the sections of the sheet are deployed covering a surface of a length approximately equal to that of the rows of posts; and -a position of opening of the cover in which all the sections of sheet are folded against their respective first fixed end.
This cover therefore allows the movement of the mobile cables in one direction or the other, the simultaneous folding or unfolding of each and every section of the sheet by means of the drive or winding and unwinding means, being sufficient for this movable cables travel in a length approximately equal to the length of one of the sections of foil.
This allows the opening or closing of the cover can be done quickly and easily.
These and other features of the invention, set out in the appended claims, will be more readily understood in view of the exemplary embodiment shown in the attached figures. Description of the figures.
To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:
- Figure 1 shows a schematic elevation view of an exemplary embodiment of the folding protection cover in the closed position.
- Figure 2 shows a view similar to the previous one with the cover in the open position.


- Figure 3 shows a schematic top plan view of an embodiment example of the cover in which two alignments of protective foil sections are shown in open position and two other alignments of sections of
5 protective foil in closed position.
- Figure 4 shows a schematic profile view of the cover of the previous figure.
10 -Figure 5 shows a detail of fixing two opposite ends of a section of protective sheet to a fixed cable and a mobile cable respectively and of the assembly of the intermediate area of said section of sheet in the fixed and mobile longitudinal cables by means of movable flanges
15 -Figure 6 shows a perspective detail of the fixation of the longitudinal and transverse fixed cables in crossing areas, by means of a fixing and longitudinal guide piece of a mobile cable. Preferred embodiment of the invention.
As can be seen in the example shown, the folding protection cover comprises: rows of posts (1) arranged in parallel, first fixed cables (2a) mounted on respective rows of posts (1), second fixed cables ( 2b) arranged between consecutive rows of posts; and some sections of
25 protective sheet (3), approximately the same length, aligned in a longitudinal direction parallel to the fixed cables (2a, 2b).
Each section of protective sheet (3) has a first end (31) fixed to the longitudinal fixed cables (2a, 2b); and a second end (32) fixed to cables
30 mobile (4a, 4b) longitudinal parallel to the fixed cables (2a, 2b).
The second fixed cables (2b) are fixed to transverse cables (5) that are secured in posts (1) of two consecutive rows.


The mobile cables (4a, 4b) are fixed at the ends opposite to simultaneous winding and unwinding means, which comprise winches (6), manually or electrically operated, which move said mobile cables (4a, 4b) over a distance. approximately equal to the length of a section of protective sheet
5 (3).
Said winches (6) move the movable cables (4a, 4b) longitudinally between: a closed position of the cover, shown in Figure 1 and in the upper part of Figure 2, in which the sections of a sheet same row is
10 found deployed covering a surface of a length approximately equal to that of the rows of posts (1); and -a position of opening of the cover, represented in figures 1 and in the lower part of figure 2, in which all the sections of sheet of the same row are folded against their respective first fixed end (31) .
15 As can be seen more clearly in Figure 5, the sections of sheet (3) have between the first end (31) and second end (32) support flanges (33) mounted loosely and with the possibility of displacement longitudinal with respect to fixed cables (2a, 2b) and mobile cables (4a, 4b).
20 Figure 6 shows a longitudinal fixed cable (2b) and a fixed transverse cable (5) fixed in a crossing area located between the rows of posts (1), by means of a fixing clip (7) and guide longitudinal of a mobile cable (4b).
The fixing clips (7) comprise a ring (71) for the loose passage and the guide of the mobile cable (4b) during its movement between the opening and closing positions of the cover.
Once the nature of the invention has been sufficiently described, as well as an example
In the preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the elements described may be modified, provided that this does not imply an alteration of the essential features of the invention claimed below.
