FIELD OF THE INVENTION The field of the invention is that of protection devices, comprising a mast and a pivoting protective panel with respect to the mast. The invention particularly relates to a sunshade device or for protection against other climatic conditions, and can be used on a terrace, in a garden, on the beach, at the edge of a swimming pool and in similar environments. STATE OF THE ART Numerous protection devices, in particular of the sun visor type, have already been proposed. For example, document FR 2 354 729 discloses an umbrella comprising a mast, and a protective panel on which a fabric is stretched, the protection panel being rotatably mounted along three axes orthogonal to the mast, to give the umbrella a variety of different positions and adaptability to climatic conditions. The mechanism for rotating the panel relative to the mast is however not very robust, which prevents to provide for this protective device a large panel.

Document FR 2 504 368 also discloses a protection device comprising a fabric stretched over an armature, the amount of the armature being offset in order to be able to associate several devices with one another to increase the protection surface without hindering it by the presence of Matt. This device has a heavier and more rigid structure to increase the protection surface offered by the individual device. The structure of the proposed device is therefore more complicated to handle, and therefore not very modular, despite the desired applications. The device is also too expensive.

In particular, an object of the invention is to provide a protective device for covering a large protective surface, while maintaining an easy to handle structure. Another object of the invention is to provide an assembly comprising a plurality of protection devices arranged so as to maximize the protection surface without the masts of the devices interfering with access. In this regard, the subject of the invention is a protection device comprising a mast and a protection panel, the protection panel comprising: a frame defining a plane of the panel, a protective surface mounted on the frame, and a frame support member, rotatably mounted relative to the mast to allow rotation of the guard panel relative to the mast in a direction orthogonal to the mast, characterized in that the protection panel further comprises a coupling frame between the frame support member and frame, and in that the coupling frame is rotatably connected to the frame support member in a direction orthogonal to the plane of the protection panel.

Advantageously, but optionally, in the assembly according to the invention, the base is a vertical wall. The protection device proposed is robust because the coupling frame of the frame on its support makes it possible to reduce the center of gravity of the protection panel near the mast, which stabilizes the entire structure.

In addition, the fact that the coupling armature is pivotally mounted relative to the frame support makes it possible to mount two identical protective devices in a symmetrical manner, by pivoting one of the armatures at 90 ° with respect to its support, for position the protective panels side by side and thus increase the protection surface. This is achieved without differentiating the parts of the two devices, and therefore without increasing the production cost of the device. The foldable frame and removable mount on the frame allows to store the panel easily and in a minimum of space.

DETAILED DESCRIPTION OF AT LEAST ONE EMBODIMENT Referring to FIG. 1a, there is shown a protection device 1, the use of which makes it possible in particular to protect itself from the sun.

The protection device 1 comprises a mast 10, which extends in a main direction, generally vertical when the protective device 1 is in a position of use. The protective device 1 further comprises a protective panel 20, which is rotatably mounted relative to the mast 10, about an axis X-X orthogonal to the direction of the mast. The mast may comprise, according to a preferred embodiment, a rod formed of two tube portions 11, 12, adapted to slide one inside the other, and a locking system 13 in translation of a portion. 12 compared to each other. Thus the rod is telescopic, it can be deployed in use, and the portion 12 can be inserted into the portion 11 to reduce the size of the mast during storage. The panel has at least two adjacent rectilinear sides forming a vertex through which it is fixed to the mast 10. According to a first embodiment, the panel has a polygonal shape, preferably square or rectangular. Alternatively, the panel has at least two adjacent rectilinear sides, and a curvilinear side interconnecting the rectilinear sides. The panel is then attached to the mast at the top formed by the two adjacent straight sides. In this way the mast 10 is offset relative to the panel and maximizes the protected area under the panel when it is deployed, that is to say when it extends orthogonally to the mast or horizontally in the position of use of the protection device 1. Very advantageously, the panel 20 is symmetrical with respect to a bisecting plane passing through the apex through which it is connected to the mast; this is the case for example of a square, a diamond, or a quarter circle. FIG. 1b shows such a plane B for a square panel. In FIG. 1b and FIG. 2, the mast 10 further comprises a jaw 14, mounted at the end of the rod, for example at the end of the portion 12, and preferably fastened thereto by bolting or screwing. The jaw 14 is thus preferably secured to the mast. The jaw 14 comprises a cylindrical housing 15, extending in an orthogonal direction X-X to the direction of the mast 10. The housing 15 is adapted to receive a cylindrical shaft 16 of a frame support member 3 described below. The cylindrical shaft 16 is rotatably mounted in the housing 15 relative to the axis of the housing, which corresponds to the axis of the shaft when it is inserted into the housing. In addition, in order to lock the cylindrical shaft 16 in rotation in the housing 15 in at least one, and preferably a plurality of different positions, the cylindrical shaft 16 comprises a plurality of flutes 160, and the jaw 14 comprises a slot (not shown) of corresponding form. The device 1 further comprises a key 17 adapted to be received in a groove through the slot of the jaw, to lock in rotation the shaft 16 in the housing 15.

Thus, one can modify the angular position of the shaft 16 relative to the housing 15 by loosening the key 17, and pivoting the shaft 16 in the housing 15. To ensure the robustness of the mechanical parts stressed as the shaft 16 and the key 17, these are advantageously made of stainless steel.

The fixed part of the jaw with respect to the mast 10, in which is formed the cylindrical recess 15 forming a housing, can in turn be made of aluminum. According to the embodiment shown in Figure 2, the housing 15 is offset laterally relative to the mast. Alternatively, the housing 15 may be in the extension of mast in the direction of extension of the mast. With reference to FIG. 3, the protection panel 20 comprises a frame support member 3. This frame support member comprises the shaft 16 and two tabs 30 extending in parallel, the tabs being fixed to the shaft 16 on either side of it, for example by screwing or bolting. The shaft 16 thus ensures, by its rotation in the housing 15, the rotary connection between the mast 10 and the panel 20. A support disc 31 is mounted on the legs 30. It comprises in this respect two slots 311 in which are welded legs. According to a first embodiment shown in FIG. 3, the support disc 31 is offset laterally with respect to the shaft 16, the tabs 30 extending in a direction orthogonal to the axis of the shaft 16 and orthogonal to the axis 16. Mast axis 10. According to an alternative embodiment, the support disk is located right of the shaft 16 when it is fixed thereto, the tabs then extending in a direction orthogonal to the axis. of the shaft 16 and parallel to the axis of the mast. In this case, if the shaft 16 is in the extension of the mast, the support disk is also in this extension. On the disk 31 is formed a through groove 310 arcuate, which will be described in more detail below.

In Figures 1a and 1b, the protective panel 20 further comprises a frame 4, defining a plane of the protective panel 20. On the frame is fixed a protective surface 5, which can be a rigid surface such that a light plate, for example made of composite materials, or a fabric, the fabric then being preferably stretched on the frame.

The fabric 5 can then be made of a woven material, of vegetable or synthetic textile type, preferably elastic to be stretched on the frame. In all cases, the protective surface 5 is advantageously impermeable, to give the protection device a rain shelter function. Referring to Figure 4, there is shown in more detail the structure of the frame 4. The one comprises three rods, including a central rod 40, and two lateral rods 41. The three rods are joined at one end by a handle 42, which is a metal structure having a gripping port for handling and transporting the frame with simplicity. The handle 42 has a generally triangular shape, two vertices of which have a connection with the lateral rods 41, and the connection with the central rod 40 being approximately mid-length of the side extending between the vertices. The central rod 40 comprises a sleeve 43 fixed to the handle 42 or integrally formed with it, and one or more telescopic rods 44 in the sleeve 43. The lateral rods are pivotally mounted with respect to the handle 42, relative to a orthogonal axis to the frame plane (which corresponds to the plane in which the handle 42 is inscribed). Thus, the lateral rods 41 can be folded against the central rod 40 to fold the frame in a convenient transport position. The frame 4 is advantageously a symmetrical part with respect to a bisecting plane passing through the vertex connecting the frame to the mast, the lateral rods 41 therefore being of the same length, and being able to be deployed at the same angle with respect to the central rod 40 .

The fixing of the protective surface 5 on the frame can be achieved for example by snapping, if the surface comprises a rigid plate. Alternatively, in the case where the protective surface 5 is a fabric 5, its attachment to the frame can be achieved by arranging in the fabric 5, on two adjacent sides, the sleeves 50 (visible in Figure la) adapted to receive the rods when the latter are deployed at the maximum relative to the central rod 40. Preferably, the maximum deployment of the two lateral rods gives the frame 4 an angular aperture corresponding to the angle between the two adjacent sides forming the apex by which the panel is tied to the mast.

In the preferred embodiment in which the panel is square or rectangular, the maximum deployment of the rods corresponds to a 45 ° angle between each lateral rod and the central rod, and therefore a 90 ° angle between the two lateral rods, corresponding to the right angle between two successive sides of the protective surface.

Thus, the lateral rods 41 extend along the two successive sides of the protective surface, and the central rod 40 extends along a diagonal of the surface. Alternatively, in the case where the protective surface 5 is rigid, the angular aperture corresponding to the maximum deployment of the two lateral rods 41 may be less than the angle between the sides of the panel forming the top. In this case, the surface 5 is still advantageously positioned on frame 4 so as to extend symmetrically on either side of the central rod 40. Preferably, the frame is both light and resistant, to be able to be easily transported but still withstand constraints such as those imposed by the wind. In this respect, it is preferably made of aluminum. Returning to FIG. 3, the protection panel 20 further comprises a coupling frame 6 between the frame support 3 and the frame 4. The coupling frame 6 comprises a base 60 adapted to be fixed on the disk 31 of the frame support. Advantageously, the base is of generally square shape, the sides of which are greater than the diameter of the disc 31 of the support element.

The coupling frame 6 also comprises arms on which can be fixed the lateral rods 41 and the central rod 40 of the frame, when the lateral rods are in the deployed position. The armature 6 thus comprises a central arm 62 and two lateral arms 61, joined at one end by the base 60. The assembly of the armature is preferably made of aluminum. The armature 6 is advantageously a symmetrical part, whose lateral arms are of the same length and whose spacing relative to the central arm 62 is identical.

The angular aperture between the lateral arms 61 corresponds to the angular aperture of the frame 4 and, preferably, to the angle between two adjacent sides of the protective surface 5. This is particularly preferable when the protective surface 5 is a stretched canvas on the frame 4. Alternatively, in the case where the protective surface 5 is rigid, the angular opening of the arms 61 of the frame 6 and the frame 4 may be less than the angular aperture of the vertex by which the panel 20 is connected to the mast 10. Thus the frame 6 is in a corner or top of the panel. In the embodiment in which the surface 5 is square or rectangular, the lateral arms 61, 62 advantageously form at their junction a right angle. The other ends of the arms 61, 62 are interconnected by an arc 63 so as to consolidate the armature. Advantageously, the lateral arms 61 each comprise a latching device 610 of the lateral rods 41 of the frame 4, allowing the removable attachment of the frame to the frame 6. Advantageously, but optionally, the central arm 62 may also comprise a device snapping of the central stem of the frame. The frame can in this way be removed from the rest of the device to store the protective surface 5 in case of non-use of the device, whose size is reduced. Advantageously, the frame 4 can be locked on the armature 6 after its snap-fastening, for example by means of a locking handle inserted in a hole 620 of the armature, the orifice comprising, in known manner, a protrusion 622 of reduced section adapted to hold the handle once in position.

The armature 6 is itself rotatably mounted on the frame support 3. For example, the armature can be mounted to the support by interconnection, the armature comprising dog teeth (not shown) adapted to cooperate with slots 312 complementary frame support. The dog teeth and the slots 312 are first aligned so as to insert the support disc 31 between the teeth of the frame 6, then the two pieces are pivoted relative to each other, the teeth dog with suitable flanges to prohibit a relative translation between the frame and the support disc 31. This connection between the frame 6 and the frame support 3 thus allows the frame to pivot relative to the support 3 around the frame. an orthogonal axis YY to the plane of the protection panel (the plane of the protection panel corresponding to the plane defined by the armature 6). This allows, by a double rotation of the protection device, comprising a rotation of the device around its mast, and a rotation of the armature relative to the frame support, to make adopt the protection device all possible configurations, allowing to adapt in particular the relative positions of the panel and the mast according to the position of the sun. In addition, the relative rotation between the frame support 3 and the armature 6 is limited to an angle defining two extreme positions of the armature relative to the support 3, corresponding to two configurations called "left" and "right" of the device protection. To limit the relative rotation between the armature and the support 3, the base 60 of the armature comprises a through orifice 600 adapted to receive a pinlock 601 system. The pin 601 is adapted to pass through the orifice 600 and be received in the groove 310 of the support 3. The device further comprises a handle 602, which can cooperate with the pin 601 to hold it tight in position in the groove 310, or, by loosening the handle, release the pin to allow its movement in the groove 310 and thus allow the rotation of the armature 6 relative to the support 3.

As indicated above, groove 310 is an arc of a circle. The angular aperture of the groove 310 defines the limit relative rotation angle between the frame support 3 and the armature 6, the pin 601 abutting against the ends of the groove 310.

Advantageously, according to the embodiment of FIG. 3, the angle of opening of the groove 310 is the additional of the angular opening of the angle of the apex through which the panel is connected to the mast, between two successive sides of the protective surface 5. The term "additional" is understood in the mathematical sense of the term, that is to say that the sum of the angular aperture of the reinforcement and that of the groove is equal to 180 °. Preferably, in the embodiment in which the protective surface is square or rectangular, the angular opening of the groove is 90 ° and that of the armature is also 90 °.

In the embodiment in which the protective surface 5 is a fabric stretched over the frame 4, the opening angle of the groove 310 is also the additional of the angular opening of the frame 4 and the frame, since this angular opening corresponds to that of the panel. The groove and the anchor lock system thus make it possible to limit the amplitude of the rotation between the reinforcement 6 and the support 3 at the angular opening of the groove. The two left and right configurations thus defined make it possible, in the very advantageous embodiment in which the protective panel 20 is a part symmetrical with respect to the bisecting plane of the apex through which it is connected to the mast, to simply have the device of protection two symmetrical arrangements of one another. In the present case, in the embodiment of FIG. 3, as shown diagrammatically in FIG. 6, the protection device may adopt symmetrical arrangements of one another by pivoting the armature 6 from an extreme configuration to the other (from left to right configuration or vice versa), and rotating the mast of the device by 180 °. According to the alternative embodiment not shown the shaft 16 is in the extension of the mast, and the support disk is also in the extension of the mast, the groove has an angular opening of 180 °, and the symmetrical provisions of the device protection are obtained by changing the configuration of the armature, and rotating the mast of the device by 90 °. The choice of the angular opening of the groove thus makes it possible, with reference to FIG. 5a, to overcome the asymmetry of the protection device that would result if the panel were fixedly mounted on the mast with respect to the direction of the mast.

In a preferred application of the protection device 1 shown in FIG. 5a, an assembly comprising two identical protection devices 1, 1 ', each comprising a panel 20, 20' square, the masts being mounted parallel to each other on a common support, are used. 7. It is then advantageous that the two protective devices 1 are respectively in the two symmetrical configurations of one another with respect to a plane of symmetry P extending between the masts, in order to maximize the protection surface and to reduce the annoyance generated by the masts. In FIG. 5a, the masts are arranged between the panels 20, 20 'of the devices (for more visibility the panels have been represented without the protective surfaces). The symmetry is allowed by the pivoting, for one of the devices, the armature 6 relative to the support of the maximum amplitude allowed by the groove 310 of the support, and the pivoting of the mast by 180 °. In this position, one of the armatures 6, 6 'is therefore in a first extreme position, left or right, authorized by the groove 310, 310' relative to the support 3, 3 ', and the other armature is in the second extreme position, right or left, allowed by the groove relative to the support. The common support 7 may be a vertical wall such as a wall, as in Figure 5a, or a common mast as in Figure 5b, provided with a fastening system 70 of the two mats 10, 10 'of the devices 1, 1 'shown in Figure 5c, the fastening system 70 comprising a metal base 71 provided with recesses 72 adapted to receive each mast, and metal hoops 73 for holding the masts against the base 71. Alternatively, the protective device 1 used alone may further comprise a base (not shown) on which the mast is fixed to maintain it in a vertical position. The mast may still have, at its end opposite the jaw 14, a pointed end (not shown) allowing it to be plugged into soft ground like sand for seaside use.
