Description

The present invention relates to the field of sun protection devices.

More particularly, the present invention relates to a shade sail, also known by the name of shade fabric or solar fabric.

The invention relates more specifically to a shade sail which is mobile so as to be able to follow the position of the sun, and to provide shade and freshness all day long.

Traditionally, the shade sails which are commercially available consist of canvas protection, of triangular, square or rectangular shape, and making it possible to provide shade and protection against the ultraviolet rays of the sun.

A shade sail is generally attached to at least one supporting wall of a dwelling, by means of a cord linked to a solid peg, suitable for masonry.

The other anchoring points of said shade sail generally consist of posts or masts positioned either in a lawn, or directly fixed at the level of a terrace, by means, for example, of plates pegged to the slab of said terrace. .

Said masts are specifically designed for the installation of such sails, and generally comprise several anchoring points allowing, for example, the adjustment of the inclination of the sail in order to avoid stagnation of water during rainy precipitation.

A shade sail can also be mounted without any wall as a fixing point, for example when one wishes to position, occasionally, his sail in the middle of the garden. In this case, the sail is necessarily suspended from masts fixedly positioned at ground level.

The disadvantage of these existing shade sails lies in the fact that they are positioned in a fixed manner, and cannot be easily moved to follow the sunshine, or to shade another location on the terrace, if the latter has a large size.

The invention offers the possibility of overcoming, at least in part, the various drawbacks of the prior art by proposing a shade sail device which has the advantage of being able to be moved in an extremely easy manner, without requiring any erection / dismantling of masts, depending on the position of the sun during the day.

To this end, the present invention relates to a mobile shade sail device characterized in that it comprises a frame capable of being pivotally mounted around a vertical axis on the facade of a dwelling, said frame comprising a plurality of anchoring points of a shading means and at least two vertical or substantially vertical uprights connected to each other upper and lower by means of a lower cross member of a straight or curved chassis, the latter being provided with rolling means or sliding means capable of cooperating with a rail formed at ground level.

In a preferred embodiment, the rolling means consist of at least two grooved wheels or at least two rollers.

Advantageously, the device of the invention further comprises means for locking the chassis at the level of the rail to avoid any untimely movement.

Preferably, said chassis blocking means are in the form of a clamp which, in the closed position, encloses said rail and blocks said chassis, the clamp being associated with means for blocking said clamp in the closed position.

Other characteristics and advantages of the invention will emerge from the detailed description which follows of nonlimiting embodiments of the invention, with reference to the appended figures in which:

- Figure 1 schematically shows a perspective view of a particular embodiment of a mobile shade sail device according to the invention;

- Figure 2 schematically shows another perspective view of an embodiment of a mobile shade sail device according to the invention;

The present invention relates to a mobile shade sail device 1.

Such a shade sail device 1 according to the invention makes it possible to create a shaded area, and therefore protection against the sun's rays, in particular UV rays, outside a dwelling, preferably at the level of a terrace.

Indeed, the device 1 according to the invention is intended, through a chassis 2, to be secured by any suitable means, at the facade of a dwelling, the latter preferably being a detached house.

Said frame 2 is, according to a specific feature of the invention, fixed to said front pivotally about a vertical axis 3 shown in the accompanying figures.

Consequently, the mobile shade sail device 1 according to the invention is particularly suitable for providing sun protection to a terrace.

The chassis 2 of said device 1 further comprises a plurality of anchor points 4 of a shading means 5, two of these anchor points 4 being represented in FIG. 1.

As regards now the shading means 5, this preferably consists of a shade cloth, which can have any type of dimensions and shapes. This canvas will however advantageously be square, rectangular, or even triangular.

Different preferred embodiments of the chassis 2, in a perspective view or from above, are shown in Figures 2, 3, 4 and 5 attached, with in particular the pivot point 3 at which said chassis 2 is fixed to the facade of the House.

However, these embodiments should not be considered as limiting the invention, and the chassis 2 can have different designs, insofar as the essential characteristics of the present invention are found there, and the rigidity of the assembly of the movable shade sail device 1 is ensured.

In particular, the frame 2 according to the invention must include a vertical part, in the form, for example, of at least two uprights 6, 7 vertical, or substantially vertical, as shown in the attached figures.

These vertical uprights 6, 7 are interconnected at their upper and lower ends, by means, respectively, of upper 8 and lower 9 crossmembers of chassis 2.

Said upper 8 and lower 9 crossmembers can be either straight or slightly curved, as is moreover preferably the case with regard to the lower crossmember 9, systematically shown in the appended figures in a curved manner, this preferred configuration making it possible to follow optimally pivoting around axis 3.

Of way particular, this cross lower 9 of frame 2 is provided with means of bearing 10 visible on the figure 2, or good, again of means of sliding no

represented.

In Figures 2 and 3, two rolling means 10 are shown. However, the lower cross member 9 may include a number of rolling means 10 greater than two, this number depending, for example, on the length of said lower cross member 9.

In all cases, said rolling or sliding means 10 act in cooperation with a rail 11, or a rod, positioned at ground level.

Most preferably, the rolling means 10 are in the form of grooved wheels or rollers.

Insofar as the lower cross member 9 is curved, the rail 11 must also follow a curved path, as illustrated in the figures, again in order to be able to optimally follow the pivoting of the chassis 2 along an axis 3.

The presence of rolling means 10 at the level of the lower cross-member 9 of chassis 2, in cooperation with the rail 11, allows fluid and easy mobility of the whole of the shade sail device 1 according to the invention throughout the length of the rail 11, depending on the positioning of the sun, to offer optimum protection against the latter's radiation throughout the day.

Indeed, a simple push of a hand by a user is sufficient to drive the device 1 in movement, and to position it in the appropriate location for protection against solar rays.

In order to fix the positioning of the shade sail device 1 at the desired location, it is possible, but not compulsory, for the latter to be provided with locking means 12 for the chassis 2 at the level of the rail, thus making it possible to avoid any unwanted movement, for example under the effect of a gust of wind or other.

The locking means 12 are illustrated in Figure 1 attached.

Referring now to Figures 6 and 7, illustrating in more detail these locking means 12, these may take the form, advantageously, of a clamp 13 adapted to pass from an open position 14, illustrated in Figure 6 , in which the frame 2 can be moved, to a closed position 15, shown in FIG. 7, where said frame 2 is on the contrary held stationary at the location desired by the user.

Said clamp 13 is preferably associated with means 16 for locking the clamp 13 in the closed position 15.

The clamp 13 comprises two clamping jaws associated with two branches each provided with a handle and pivotally mounted on the frame 2, so that in the closed position 15, they enclose the rail 11, the locking means 16 being under the shape of an arm pivotally mounted by one of the ends on one of the branches, while its other end is able to cooperate in blocking with the other branch to keep the two branches apart, and therefore the jaws in position closed.

Advantageously, the end of the arm which cooperates in blocking with a branch, is provided with a multiplicity of notches making it possible to refine the wedging.

Of course, the invention is not limited to the examples illustrated and described above which may have variants and modifications without departing from the scope of the invention.

In particular, it is also conceivable that the shade sail device 1 according to the invention comprises a second means of protection against the sun's rays, the latter then being arranged vertically or substantially vertically at the vertical uprights 6, 7 of the chassis 2, to provide protection against shaving rays at sunrise or sunset.
