Technical field and state of the art

The present invention relates to the field of sun protection for protecting the sun by creating shade from a fabric above the user.

Conventionally, umbrellas consist of several whales adapted to fix a fabric or canvas. This type of umbrella has the disadvantage of making it difficult to remove hot air under the fabric due to the substantially conical shape of the fabric. In addition, it is impossible to use an umbrella in strong winds because the umbrella can fly away or turn around endangering nearby users.

In order to save space and prevent an umbrella from turning around, it is known to use a deported mast. The deported mast is a mast whose axis is off center to the center of the surface of the fabric. US2828758 discloses an umbrella having a remote mast having a circular surface fabric. The size of this type of umbrella does not allow easy storage and disassembly by the user because it is not possible to fold.

Description of Embodiments of the Invention

FIGS. 1 and 2 show a sun protection assembly 1 comprising a support bar 2 on which at least a first whale 3 and a second whale 4 are adapted to give a shape to a web 5. The first whale 3 and the second whale 4 are flexible and for example made of a type of fiberglass material, steel, composite, carbon ... The fabric 5 may be elastic or has a particular cut to force each whale 3, 4 to take the shape of the cut. The elasticity of the fabric 5 depends on the chosen material.

The fabric 5 is positioned between the first whale 3 and the second whale 4 so as to cover the surface delimited by the circumference formed by the first whale 3 and by the second whale 4. According to a variant of the invention, the fabric 5 is positioned between the first whale 3 and the support bar 2 so as to cover the surface defined by the circumference formed by the first whale 3 and the support bar 2.

Each whale 3, 4 has a first end 6 and a second end 7. The second ends 7 of the first whale 3 and the second whale 4 are fixed on a movable attachment means 8. This movable attachment means 8 is slidably mounted. relative to the support bar 2. The first ends 6 of the first whale 3 and of the second whale 4 are fixed on a fixed attachment means 9. This fixed attachment means 9 is mounted integral with one end of the support bar. support 2.

The movable fixing means 8 makes it possible to vary the position of the second ends 7 of the first whale 3 and of the second whale 4 so as to change the shape of the surface of the fabric 5. For example, FIG. positioning the trajectory of the first whale 3 and the second whale 4 shown in dotted line. In this way, the first whale 3 and the second whale 4 can vary substantially from a surface of a disc to a surface near the section of the support bar 2. When the wrap 5 has a substantially disk shape, the distance between the movable fixing means 8 and the fixed fixing means 9 is minimal, that is to say, as in the second configuration, called open. When the fabric 5 is close to the section of the support bar 2, the distance between the movable fixing means 8 and the fixed fixing means 9 is maximum, that is to say as on the first configuration, so-called closed. Preferably, the first whale 3 and the second whale 4 are symmetrical with respect to the support bar 2.

The sun protection assembly 1 is mounted articulated on a mast 1 1. This articulated connection 13 makes it possible to pivot the support bar 2 with respect to the axis of the mast 1 1 and to pivot the support bar 2 with respect to a perpendicular to the axis of the mast 1 1.

According to a variant of the invention, the support bar is telescopic. In this case, the second ends 7 of the first whale 3 and the second whale 4 are fixed on a fixed attachment means 6 at one end of the telescopic support bar. The first ends 6 of the first whale 3 and the second whale 4 are fixed on a fixed fixing means 6 at another end of the telescopic support bar. The telescopic support bar slides and varies the distance between the two fixed fixing means 9 for varying the shape of the surface of the fabric 5.

In FIG. 3, the movable fixing means 8 is slidable relative to the support bar 2. An adjustment means 10 makes it possible to maintain the mobility in a rail of the support bar 2 and to ensure the necessary and sufficient tension to maintain the movable fixing means 8 at the desired location on the support bar 2. The adjustment means 10 may for example be made by a cord for moving the movable attachment 8. For example, this cord is energized to lock the movable attachment means and maintains the desired position by the user. According to another embodiment, the cord is locked at one end of the support bar 2 and maintains the position desired by the user on the support bar 2.

The mobile attachment means 8 comprises a first holding means 81 of the second end 7 of the first whale 3 and a second holding means 82 of the second end 7 of the second whale 4. The first holding means 81 and the second means 82 hold each end of each whale 3, 4 and pivot about an axis relative to the movable attachment means 8.

The variation of the position of each holding means 81, 82 makes it possible to give a particular shape to the surface of the fabric 5.

The first holding means 81 and the second holding means 82 are inclined relative to each other about the longitudinal axis of the support bar 2 at an angle γ, so as to position the fabric 5 above of the support bar 2. In this way, the support bar 2 can support the first whale 3 and the second whale 4 above the level of the support bar 2. As seen in FIG. 4, the first holding means 81 and the second holding means 82 vary their position as a function of the angle α of the order of 90 °, that is to say that the axis passing through the apex of the angle α is a parallel to the longitudinal axis of the support bar 2 at a perpendicular to the longitudinal axis of the bar 2. The fabric 5 may be pre-cut to give a shape such as for example the fabric 5 has a substantially oval shaft leaf shape and constrains the first holding means 81 and the second holding means 82 in a desired configuration by the shape of the wire 5.

According to one variant, the first holding means 81 and the second holding means 82 are locked in position so that the fabric 5 forms a desired surface such as, for example, a substantially oval tree leaf.

In the same way, the fixed fixing means 9 also comprises a first holding means 81 and a second holding means 82 which vary their position as a function of the inverse of the angle a. The first holding means 81 and a second holding means 82 make it possible to maintain and position the first end 6 and the second end 7 of the first whale 3 and the second whale 4.

Each whale 3, 4 is connected to the fixed fixing means 9 and the movable attachment means 8 by an axis which leaves a degree of freedom in rotation which, depending on the stiffness of the whales and / or the shape of the fabric 5 , on the one hand to obtain a form of round or pointed fabric and on the other hand to fold each whale 3, 4 along the support bar 2. According to another variant of the invention, the means of setting 10 can also be motorized.

For example, a worm system moves the movable attachment means.

Figures 4 and 5 show the articulated connection 13 between the support bar 2 and the mast 1 1. The possibilities of rotation are similar to a ball joint. The articulated connection 13 makes it possible to turn the support bar 2 about its longitudinal axis, the maintenance of the good position is ensured by a first locking in rotation 131. The articulated connection 13 pivots according to the angle β of the order of 180 ° in the vertical plane of the articulated connection, the maintenance of the correct position is ensured by a second locking in rotation 132. The second locking in rotation 132 is a pin which blocks the rotation of the articulated connection 13. The articulated connection 13 can also rotate around the axis of the mast 1 1, a third rotational locking 133 ensures the position of the articulated connection 13 relative to the mast 1 1. In this way, the sun protection assembly 1 can be positioned in all positions to meet the needs of the user.

Figures 6 and 7 show two views of a movable foot 12 provided to carry the mast 1 1 or the sun protection assembly 1. The movable foot 12 comprises a movable moving means between a storage position and a position of use. The moving means comprises wheels 121 and 122. The rollers are on a movable axis and movable via a pedal 123. In this way, by the action of the user, the pedal 123 moves the axis the rollers 121 and 122 so as to bring out the rollers below the movable foot 12. The pedal 123 comprises a high position and a low position respectively corresponding to a storage position and a position of use of the movable stand 12.

According to a variant, it is possible to add around the movable foot 12 rings, for example cast iron, in order to increase the weight of the movable foot, especially when the mast 1 1 supports several set of sun protection 1. The foot mobile 12 also includes a means for inserting the mast 1 1 or the sun protection assembly 1.

Figures 8 to 10 show a second embodiment. This second embodiment is to be compared with FIGS. 3 to 5.

FIG. 8 represents the movable fixing means 8 secured to the adjustment means 10. In this example, the adjustment means 10 make it possible to maintain the mobility by a braking element which is in constant contact with the support bar 2. When the a force is exerted on a trigger of the adjusting means 10, the braking element is no longer in contact with the support bar 2, which makes it possible to adjust the movable fixing means 8 to the desired position.

In the same way as the description of FIG. 3, the movable fixing means 8 of FIG. 8 comprises a first holding means 81 of the second end 7 of the first whale 3 and a second holding means 82 of the second end 7. of the second whale 4. In this example, the first holding means 81 and the second holding means 82 are identical.

The first holding means 81 and the second holding means 82 are of tubular shape adapted on one side to receive a first end 6 or second end 7 of the first whale 3 or the second whale 4 and on the other side to rotate according to the angle α with respect to the movable attachment 8.

Figures 9 and 10 show the articulated connection 13 between the support bar 2 and the mast 1 1 in the same manner as the description of Figures 4 and 5. Indeed, the rotation possibilities are similar to a ball joint. The articulated connection 13 makes it possible to turn the support bar 2 about its longitudinal axis, the maintenance of the good position is ensured by a first locking in rotation 131. Arrows in FIG. 10 show that the support bar 2 can rotate according to the longitudinal axis of the support bar 2 to 360 °, if the first block 131 is not tight. The articulated connection 13 pivots according to the angle β of the order of 180 ° in the vertical plane of the articulated connection, maintaining the correct position is ensured by a second rotational locking 132.

The second rotational locking 132 is composed of a U-shaped profile which blocks the rotation of the articulated connection 13. When pressure is exerted on the U-shaped profile on the side of its ends, the locking means 13 frees the degree of freedom in rotation between the mast 1 1 and the support bar 2, the user can then choose the desired inclination. When there is no more pressure, a return spring exerts a return on the U-shaped profile which engages and blocks the degree of freedom of the articulated connection 13. A third rotational locking 133 makes it possible to tighten and to fix the articulated connection 13 to prevent rotation along the longitudinal axis of the mast 1 1 according to the position desired by the user. When the third rotational locking 133 is not tight, there is a degree of freedom in rotation along the longitudinal axis of the mast 1 1 between the mast 1 1 and the hinged connection 13.

The first blocking 131, the second blocking 132 and the third blocking 133 represent the 3 offset axes of rotation comparable to a ball joint.

FIG. 11 represents a plurality of sun protection assemblies 1 positioned on a mast 1. Each sun protection assembly 1 comprises an articulated connection 13. More particularly in FIG. 12, the fabric 5 of each sun protection assembly 1 has a particular shape such as for example a circular disk or a substantially oval tree leaf.

FIG. 13 represents a variant of the solar protection assembly 1. In this case, the sun protection assembly 1 comprises a third whale 14. The woven fabric 5 is disposed between each whale and makes it possible to create a volume around it of the sun protection assembly 1. In this case, the sun protection assembly 1 is positioned directly on the movable foot 12. Figure 14 shows a sectional view of the fixed attachment means 9 of a sun protection assembly 1 as shown in Figure 13. The fixed fixing means 9 comprises a first holding means 81, a second holding means 82, a third holding means 83 shown in dashed lines. Each holding means 81, 82 and 83 supports whales. The fabric 5 is positioned between each whale and is fixed on the fixed fastening means 9 on the web support 51.

FIG. 15 represents a sectional view of the movable fixing means 8 comprising a first holding means 81 and a second holding means 82. The third means of hold 83 is not shown. The movable fixing means 8 comprises the first rotational locking 131.

FIG. 16 represents a sectional view seen from above of FIG. 15. The adjustment means 10 make it possible to fix the position of the movable fixing means 8 along the longitudinal axis of the support bar 2. It is also represented a section of the first whale 3, the second whale 4, the first holding means 81, a second holding means 82 and the first rotational locking 131.

FIG. 17 represents a profile view of the first rotation lock 131. The movable fixing means 8 can rotate about the longitudinal axis of the support bar 2. The first rotational locking 131 makes it possible to fix the position of the mobile attachment 8. Indeed, when the whales are stretched, a movable member 134 of the first rotational locking 131 is positioned in one of the notches of the movable fixing means 8 so as to block the rotation and therefore the position of the fastening means 8. When the whales are substantially parallel to the axis of the support bar 2, there is no pressure exerted on the movable member 134. For example, Figure 17 shows a second whale 4 parallel to the longitudinal axis of the support bar 2. The movable element 134 is not positioned in one of the mobile attachment means notches 8 and the movable fixing means 8 is then free to rotate about the longitudinal axis of the support bar 2.

In another variant, the sun protection assembly 1 also comprises a light means adapted to be positioned in the support bar 2 disposed between the movable fixing means 8 and the fixed fixing means 9.

Of course, the invention is not limited to the embodiments described and represented by way of examples, but it also includes all the technical equivalents as well as their combinations.
