Description

Invention background

The present invention relates to the field of camping equipment. More specifically, the invention relates to a foldable tent that can take a folded position, corresponding to a storage position, and a deployed position, corresponding to a position of use.

This type of tents is commonly used by hikers and campers. Indeed, foldable tents can be quickly deployed or folded, allowing the installation or quick storage of a bivouac.

We know folding tents like the one described in the document US3941140 . The tent includes a first sub-frame and a second sub-frame, each of the sub-frames comprising a plurality of rods pivotally connected to a hub. The two sub-frames form two rectangles inclined towards each other to define the interior volume of the tent.

A disadvantage of this tent is that it has a particularly reduced interior volume which does not offer the comfort necessary for the user. The head and feet of a user lying in the foldable tent may especially touch the tent which is particularly unpleasant and compromises the sleep of the user.

In addition, to place the tent in the deployed position, it is necessary to manually rotate each of the rods relative to the corresponding hub, in order to form the two sub-frames. These rods must be manually rotated, one after the other. As the tent has eight rods, setting up the tent is therefore long and complicated. In addition, the effort to produce to rotate said rods can become particularly significant due to the tension exerted by the tent fabric on the already pivoted rods.

Similarly, to store this tent, it is necessary to rotate the rods again, in a second direction, in order to bring each of the sub-frames into a folded position. Again, the efforts to be exerted to pivot the rods can be significant. In addition, the user must move gradually around the tent in order to reach each of the rods, which is tiring and does not allow the tent to be folded up quickly. The storage of the tent is therefore also very long and complicated, not very instinctive and may cause fatigue for the user.

Subject and summary of the invention

An object of the present invention is to provide a foldable tent overcoming the aforementioned problems.

• a tent canvas;
• a first mastless umbrella structure comprising a first upper hub, a first lower hub, a plurality of ribs hingedly connected to the first upper hub and cooperating with the tent canvas, a plurality of counter-ribs, each counter-rib of the first umbrella structure having a first end part hingedly connected to one of the whales of said first umbrella structure and a second end part hingedly connected to the first lower hub, the whales and counter whales of the first umbrella structure being arranged so that the first lower hub is movable relative to the first upper hub in a first direction of movement, said first umbrella structure being able to assume an open position and a closed position;
• a second mastless umbrella structure comprising a second upper hub, a second lower hub, a plurality of ribs hingedly connected to the second upper hub and cooperating with the tent canvas, a plurality of counter-ribs, each counter-rib of the second umbrella structure having a first end part hingedly connected to one of the whales of said second umbrella structure and a second end part hingedly connected to the second lower hub, the whales and counter whales of the second umbrella structure being arranged so that the second lower hub is movable relative to the second upper hub in a second direction of movement, said second umbrella structure being able to assume an open position and a closed position; and
• at least a first junction configured to articulate the distal end of a first whale of the first umbrella structure and the distal end of a first whale of the second umbrella structure,

the tent being able to assume a deployed position in which the first and second umbrella structures are in the open position and a folded position in which the first and second umbrella structures are in the closed position.

By distal end of a whale is meant the end of said whale opposite to the upper hub to which it is connected.

The first and second umbrella structures are preferably identical.

The tent fabric advantageously comprises an entry door and ventilation openings. It is preferably integral with the first umbrella structure and the second umbrella structure. The tent fabric is advantageously carried by the whales of the first and second umbrella structures. It can also be integral with the first upper hub, the first lower hub and / or the ribs of the first umbrella structure.

In the folded position, all of the tent whales and counter-whales extend substantially parallel so that the tent forms a bundle. It can then be stored in a storage cover of cylindrical shape.

Preferably, each counter whale is connected to a corresponding whale by means of an articulation, allowing said counter whale to pivot relative to said whale.

Without limitation, the first junction connecting the distal ends of the first whales of the first and second umbrella structures may consist of a pivot link, such as a hinge, or a ball joint. It allows the first whales and therefore the first and second umbrella structures to pivot relative to each other. The first junction also connects the first and second umbrella structures when the tent is in the folded position. This avoids losing one of the umbrella structures.

The tent is deployed by successively opening the two umbrella structures. Alternatively, the two umbrella structures can be opened simultaneously.

To place the first umbrella structure in the open position, the user moves the first lower hub to the first upper hub. This movement can be achieved by pushing the first lower hub towards the first upper hub from inside the foldable tent. This movement can also be achieved by pulling the first lower hub towards the first upper hub from outside the foldable tent.

This movement of approach from the first lower hub to the first upper hub has the effect of rotating the whales of the first umbrella structure relative to the first upper hub, which causes them to move away from the first direction of movement.

Preferably, the passage of the first lower hub beyond a plane perpendicular to the first direction of movement and containing the articulations between the whales and the counter-whales of the first umbrella structure causes the locking of the first umbrella structure in position. opened. The passage of this plane is also called the passage of hard point. It is accompanied by an inversion of the angle of inclination between the first lower hub and the counter-ribs of the first umbrella structure, and by a tensioning of said counter-ribs. When the first lower hub is between this plane and the first upper hub, the counter-ribs relax and exert a thrust on the first lower hub which then automatically heads towards the first upper hub.

Preferably, in the open position, the first lower hub is pressed against the first upper hub. The open position of the first umbrella structure is therefore a stable position.

The procedure for placing the second umbrella structure in the open position is similar to that for placing the first umbrella structure in the open position. The umbrella structures allow each of the whales to be deployed simultaneously and can therefore be opened quickly and effortlessly.

When deploying the foldable tent, the first junction in particular makes it possible to pivot said umbrella structures and therefore to position them relative to one another. When one of the two umbrella structures is placed in the open position, the first junction guides the movement of the other umbrella structure. It also allows a clearance between said first whales facilitating the positioning of the two umbrella structures in relation to each other and limiting the efforts liable to damage the roof of the folding tent when the latter is deployed.

In particular, the successive open position of the two umbrella structures makes it possible to automatically shape the roof of the tent and thus define an interior volume. Thanks to the invention, the foldable tent can therefore be deployed very quickly, by moving the first and second lower hubs, with a minimum of effort.

The two umbrella structures form the frame of the tent. The first junction advantageously forms a top of the foldable tent on which the tent fabric rests. Advantageously, considered vertically, the first and second upper and lower hubs extend below the first junction and therefore from the top of the foldable tent.

Considered from inside the tent, the umbrella structures have a concave profile, increasing the interior volume of the tent as a result of which the comfort of the user is improved.

The tent fabric advantageously exerts a tension on the first and second umbrella structures making it possible to keep them fixed relative to one another when the foldable tent rests on the ground.

The foldable tent preferably comprises at least three whales, more preferably four, the distal ends of which are configured to rest on the ground when the tent is deployed, so that said tent is sufficiently stable.

Preferably, the foldable tent further comprises an interior chamber disposed under the tent fabric and mounted on the first and second umbrella structures. The interior chamber is configured to house the user.

To fold the tent, it is necessary to successively bring the two umbrella structures in the closed position. Alternatively, the two umbrella structures can be brought into the closed position simultaneously.

To bring the first umbrella structure into its folded position, the user must move the first lower hub away from the first upper hub, for example by pulling the first lower hub from inside the tent or by pushing the first lower hub from the outside the tent, so that the first lower hub again passes the aforementioned plane and therefore the hard point.

The procedure for placing the second umbrella structure in the closed position is similar to that for placing the first umbrella structure in the closed position.

When the folding tent is placed in the folded position, the two umbrella structures rest on the ground. The user can then collect them so as to form a bundle and place them in a storage bag. The whales can be kept together by means of a strap.

Advantageously, the second direction of movement is inclined relative to the first direction of movement when the folding tent is placed in the deployed position. Preferably, the angle between the first direction of movement and the second direction of movement is between 70 ° and 100 ° and more preferably approximately equal to 90 °.

Said directions of movement are preferably inclined relative to the ground, when the foldable tent rests on the ground. In addition, the plane passing through the joints between the whales and the counter whales of the first umbrella structure is also inclined relative to the ground. Also, the roof of the tent forms a dome to shelter the user.

Advantageously, placing one of the two umbrella structures in the open position causes the other umbrella structure to pivot relative to the ground and therefore automatically guides the inclination of this other umbrella structure relative to the ground. Preferably, each of the umbrella structures forms a support allowing the other umbrella structure to be inclined relative to the ground.

In the deployed position, the directions of movement are advantageously directed towards the torso of the user standing near the convex side of the umbrella structures. In addition, the first and second upper and lower hubs advantageously extend at the size of this user. Said hubs are therefore particularly accessible, which facilitates the placing in the open and closed position of the first and second umbrella structures. This facilitates the deployment of the tent and reduces fatigue and any physical trauma associated.

In the folded position of the foldable tent, the first and second directions of movement preferably extend substantially parallel.

Preferably, the first and second umbrella structures extend on either side of a vertical plane passing through the first junction, when the folding tent is placed in the deployed position and rests on the ground. Said vertical plane advantageously forms a plane of symmetry for the roof of the foldable tent. This conformation improves the stability of the tent on the ground.

Preferably, the first junction comprises a first sheath configured to receive the distal ends of the first whales of the first and second umbrella structures. One advantage is to connect and guide said first whales while providing enough freedom for these first whales to pivot and position themselves relative to each other during the deployment of the tent. The efforts required to deploy the tent are therefore reduced. The first sheath advantageously forms a ball joint between said first whales.

Said first sheath is preferably fixed, for example sewn, to the tent canvas, so that the first ribs cooperate with the tent canvas so as to carry and tension it when the foldable tent is deployed.

In a nonlimiting manner, said first sheath can comprise a first portion of sheath configured to receive the distal end of the first whale of the first umbrella structure and a second portion of sheath configured to receive the distal end of the first whale of the second umbrella structure.

According to a particularly advantageous aspect of the invention, the first whale of the first umbrella structure comprises a first portion of whale, a second portion of whale and a hinge connecting said first and second portions of whale so as to pivot around a transverse axis. to said first and second whale portions, said first umbrella structure being configured to bring the second whale portion into an unfolded position, when the first umbrella structure is brought into the open position, and to bring the second whale portion to a folded position, when the first umbrella structure is brought into the folded position.

The counter whale associated with the first whale cooperates advantageously with the first portion of whale of said first whale.

In the open position of the first umbrella structure, the first and second whale portions are preferably aligned and extend in continuity with each other. In the folded position, the first and second portions of the whale preferably form an angle with respect to each other. The hinge forms a pivot connection between the first and second portions of the whale.

The second portion of the whale has the advantage of increasing the interior volume of the folding tent when the latter is placed in the deployed position, as a result of which the comfort of the user is improved. This second portion of folding whale also makes it possible to increase the compactness of the foldable tent when folded. Indeed, in the folded position, the second portion of the whale extends substantially parallel to the first portion of the whale. The first and second whale portions then extend next to each other, which makes it possible to store them in a storage bag of reduced size.

The opening of the first umbrella structure automatically brings the second portion of the whale in the unfolded position. Similarly, closing the first umbrella structure automatically brings the second portion of the whale in the folded position. The user is not required to unfold the second portion of the whale manually. It is therefore understood that the deployment of the tent is further facilitated.

Preferably, several whales of the foldable tent include such first and second portions of whale. More preferably, each of the umbrella structures includes four whales having such first and second whale portions. This further increases the volume of the deployed tent and the compactness of the folded tent. In this advantageous variant, each of the second portions of the whale are unfolded simultaneously when the umbrella structure is opened.

Advantageously, the first upper hub can comprise an attachment portion, such as a hook, and the distal end of the first whale of the first umbrella structure can be provided with a fixing element, such as an elastic, configured to cooperate with the attachment portion so as to releasably maintain said second portion of the first whale in the folded position.

Advantageously, said hinge is configured to limit the pivoting of the second portion of whale relative to the first portion of whale when said second portion of whale is unfolded. It is understood that the pivoting of the second portion of the whale is interrupted when the first and second portions of the whale extend into the extension of each other. The tension exerted by the tent fabric on the first whale advantageously makes it possible to maintain the second portion of whale in the unfolded position.

The angular travel of the second portion of the whale between the folded position and the unfolded position is preferably between 170 ° and 190 ° and more preferably approximately equal to 180 °. In the unfolded position, the second portion of the whale extends in continuity with the first portion of the whale.

Preferably, the foldable tent has an interior volume defined by the first and second umbrella structures, when it is placed in the deployed position, and said hinge is configured to move towards the interior volume when the first umbrella structure is brought from its open position. towards its closed position. In other words, the second portion of the whale pivots outward from the interior volume when the first umbrella structure is closed.

The movement of the hinge is preferably carried out by gravity, under its own weight. This movement tends to bring the distal end of the first whale and the first upper hub closer to each other. This allows the user to easily assemble the first and second portions of whale to form a bundle, and therefore facilitates the storage of the folding tent.

Advantageously, the tent fabric is connected to said hinge. One advantage is to guide the tent fabric between the first and second portions of the whale when the first umbrella structure is brought into the folded position, and thus contain it substantially in the first closed umbrella structure. The compactness of the folded tent is improved.

Preferably, the roof comprises at least a second junction configured to articulate the distal end of a second whale of the first umbrella structure and the distal end of a second whale of the second umbrella structure.

The second junction is preferably identical to the first junction. The tent advantageously has a longitudinal vertical plane of symmetry, the first and second junctions extending on either side of said longitudinal vertical plane of symmetry. The first and second junctions preferably extend at the same height and jointly form an upper part of the tent.

The second junction preferably comprises a second sheath.

Preferably, the first and second umbrella structures each include third and fourth whales each having a distal end configured to rest on the ground when the foldable tent is placed in the deployed position. One advantage is to ensure the stability of the tent, even on uneven terrain. The first and second ribs therefore allow the connection between the umbrella structures, while the third and fourth ensure the stability of the folding tent.

The distance separating the distal ends of the first and second ribs from an open umbrella structure is preferably less than or equal to the distance separating the distal ends of the third and fourth ribs from said umbrella structure.

Alternatively, each of the umbrella structures may have only one whale, the distal end of which is configured to rest on the ground when the foldable tent is deployed. Also, in this variant, only two ribs of the foldable tent are in contact with the ground. The foldable tent can then comprise a plurality of stabilization members configured to improve the stability of the tent, for example guy lines. These guy lines may have a first end cooperating with the roof of the folding tent and a second end, opposite the first end, configured to be anchored to the ground.

Preferably, the first umbrella structure comprises a fifth whale having a distal end cooperating with a cooperation portion of the tent fabric, the fifth whale having a length less than the length of the third and fourth whales of the first umbrella structure and s' extending between said third and fourth whales.

Said fifth whale makes it possible to spread the tent fabric outwards from the foldable tent, so as to increase the interior volume defined by said tent fabric. This improves user comfort.
the tent cloth cooperates with the distal end of the fifth whale. Lines of tension are formed on the tent canvas between the distal ends of the third, fourth and fifth whales. This allows to stretch a portion of triangular tent canvas forming a vertical panel extending between the third and fourth whales. The tent fabric is therefore not inclined at this point, which prevents the head or feet of the user lying in the foldable tent do not touch the tent canvas. User comfort is therefore improved.

Advantageously, the ribs of the first umbrella structure each have a distal end, the tent fabric cooperating with said distal ends. Said distal ends are preferably integral with the tent fabric. Tension lines are advantageously formed on the tent canvas between the distal ends of the whales of the first umbrella structure. An interest is to stretch the tent canvas to prevent it from moving in the wind. This notably reduces the noise nuisance for the user of the tent. In addition, the tent fabric makes it possible to tension said whales in order to give them a convex shape.

Advantageously, the tent fabric also cooperates with the distal ends of the whales of the second umbrella structure.

Preferably, the tent fabric is also connected to the first upper hub. Also, a tension line is formed on the tent canvas between the distal end of the whales of the first umbrella structure and the first upper hub. In the embodiment where one or more whales of the first umbrella structure comprise first and second portions of whale hinged together, this tension makes it possible to automatically bring said second portions of whale in the unfolded position, when the opening of the first umbrella structure. It is the same for the second umbrella structure.

Advantageously, the tent fabric has a peripheral edge, and said peripheral edge is connected to the distal ends of said third and fourth ribs of the first umbrella structure. The peripheral edge therefore extends partly near the ground and the tent canvas almost completely covers the first and second umbrella structures.

When the first umbrella structure comprises a fifth whale, the peripheral edge of the tendon can be connected to said fifth whale so as to distance the peripheral edge from the ground and thus form a ventilation. Alternatively, the cooperation portion of the fifth whale with the tent fabric can be separate from the peripheral edge.

Preferably, the first upper hub has a through hole, the first umbrella structure further comprises an actuating element fixed to the first lower hub and through the hole, whereby the first umbrella structure is brought into the open position in exerting traction on the actuating element from outside the foldable tent, so as to bring the first lower hub closer to the first upper hub in order to cause the deployment of the whales.

Preferably, the actuating element is a cord fixed to the first lower hub. To bring the foldable tent into the deployed position, the user pulls on the cord which causes the deployment of the whales.

Preferably, the first lower hub has a diameter less than the diameter of the first upper hub. One advantage is to facilitate the spacing of the ribs of the first umbrella structure and therefore the displacement of the first lower hub relative to the first upper hub.

Preferably, the first whale of the second umbrella structure comprises a first portion of whale, a second portion of whale and a hinge connecting said first and second portions of whale pivotally, the roof of the foldable tent being shaped so that a tension line is formed on the tent fabric between the distal end of the third whale of the first umbrella structure and said hinge, when the first umbrella structure is open. One advantage is to keep the distal end of the first whale of the first umbrella structure above the ground when the latter is only open. In other words, this tension line keeps the first umbrella structure inclined relative to the ground when it is only open.

Thanks to this inclination, the second umbrella structure easily pushes upwards on the first umbrella structure when it opens and causes the first umbrella structure to pivot relative to the ground, towards its final inclination.

Detailed description of the invention

The invention relates to a foldable tent comprising two umbrella structures and which can take a folded position, corresponding to a storage position, and a deployed position, corresponding to a position of use.

The figure 1 illustrates a foldable tent 10 according to the present invention, placed in the folded position.

The foldable tent 10 comprises a roof 12 which consists of a tent fabric 14, a first umbrella structure 16 and a second umbrella structure 16 '. For reasons of readability, the tent fabric 14 is not shown on the figure 1 but is visible on the figure 8 .

As can be seen on this figure 1 , the first umbrella structure 16 comprises a first upper hub 18, a first lower hub 20, as well as a plurality of ribs hingedly connected to the first upper hub 18. More specifically, the first umbrella structure 16 comprises first 21, second 22, third 23, fourth 24 and fifth 25 whales. In this nonlimiting example, these ribs are pivotally mounted relative to the first upper hub 18.

The first umbrella structure 16 further comprises first 26, second 27, third 28, fourth 29 and fifth 30 counter whales. Each of these counter-whales comprises a first end part 26a, 27a, 28a, 29a, 30a and a second end part 26b, 27b, 28b, 29b, 30b, opposite the first end part. The first end portions of the first 26, second 27, third 28, fourth 29 and fifth 30 counter whales are connected in a manner articulated respectively to the first 21, second 22, third 23, fourth 24 and fifth 25 whales by means of articulations 32. The second ends of the first, second, third, fourth and fifth counter-whales are connected in a manner articulated to the first lower hub 20. In this nonlimiting example, the counter- ribs 26, 27, 28, 29, 30 are pivotally connected to the first lower hub 20 and to the ribs.

As illustrated in figure 2 , the whales and the counter-whales of the first umbrella structure are arranged so that the first lower hub 20 is movable in translation relative to the first upper hub 18 in a first direction of movement Y1 . The first umbrella structure 16 forms an umbrella structure without a mast.

The first 21, second 22, third 23 and fourth 24 whales of the first umbrella structure 16 each have a first portion of whale 34, a second portion of whale 36 and a hinge 38 pivotally connecting said first and second portions of whale. The hinges 38 are configured so that the second portions of whale 36 pivot relative to the first portions of whale 34 along axes transverse to said first and second portions of whale. The second portions of whale 36 can take an unfolded position in which they extend in continuity with the first portions of whale 34, as illustrated in figure 2 . The second portions of whale 36 can also take a folded position in which they form an angle with the first portions of whale 34, as illustrated in figure 1 .

Said hinges 38 are configured to limit the pivoting of the second whale portions 36 relative to the first whale portions 34, when said second whale portions are brought into the unfolded position. The angular movement of the second whale portions 36 is approximately 180 ° between the folded position and the unfolded position.

In the folded position of the foldable tent 10, illustrated in figure 1 , said second portions of whale 36 are in the folded position.

The fifth whale 25 of the first umbrella structure comprises a first portion of whale 34 but no second portion of whale. Also, the fifth whale 25 has a length shorter than that of the other whales 21,22,23,24. The fifth whale 25 extends between the third and fourth whales 23, 24 of the first umbrella structure 16.

On the figure 2 , it is noted that the first upper hub 18 has a diameter D1 greater than the diameter D2 of the first lower hub 20 and that the first upper 18 and lower hubs 20 are coaxial.

On the figure 2 , in which the second whale portions 36 have been unfolded, it can be seen that the first lower hub 20 has an elongated portion 40. The first lower hub 20 also has one end forming a bearing portion 42 disposed at the top of the portion elongated 40. The first upper hub 18 also has a through hole 44 which opens axially on either side of the first upper hub 18.

To allow its opening, the first umbrella structure 16 further comprises a cord 46, forming an actuating element, which is fixed to the first lower hub 20 and which passes through the orifice 44. The cord 46 is fixed to the portion d support 42 of the first lower hub 20, passes through the first upper hub 44, and has one end provided with a first gripping ring 48.

The first umbrella structure 16 can be placed in an open position and in a closed position. In the folded position of the tent, illustrated in figure 1 , the first umbrella structure 16 is placed in the closed position.

The second umbrella structure 16 ' is identical to the first umbrella structure 16 so that it comprises a second lower hub 20', a second upper hub 18 ', and a plurality of ribs and counter-ribs. More specifically, the second umbrella structure 16 ' comprises first 21', second 22 ', third 23', fourth 24 ' and fifth 25' whales and first 26 ', second 27', third 28 ', fourth 29' and fifth 30 ' counter whales. The counter-whales are connected to the second lower hub 20 ' and to the whales via joints 32'. The second lower hub 20 ' is movable in translation relative to the second upper hub 18' in a second direction of movement Y2. The first, second, third and fourth ribs of the second umbrella structure 16 ' each include a first portion of rib 34' and a second portion of rib 36 ' hingedly connected via a hinge 38'. The second lower hub includes a bearing portion 42 '. The second umbrella structure 16 'also includes a second cord 46' provided with a second grip ring 48 ' and connected to the second lower hub 20 '. The second umbrella structure 16 ′ can also be open or closed.

On the figure 1 , it can be seen that the foldable tent 10 is in the folded position and the first and second umbrella structures 16, 16 ' are in the closed position. The second portions of whale 36.36 ' of the two umbrella structures 16.16' are in the folded position so that all of the first 34.34 ' and second 36.36' portions of whale extend substantially parallel to one another and parallel to the first and second directions of movement Y1, Y2.

The first whale 21 of the first umbrella structure 16 has a distal end 21a opposite to the first upper hub 20. Likewise, the first whale 21 ' of the second umbrella structure 16' has a distal end 21'a opposite to the second upper hub 20 '. Said distal ends 21a, 21'a of the first whales 21,21 ' of the first 16 and second 16' umbrella structures are engaged in a first sheath 50 sewn to the tent fabric 12. This first sheath 50 makes it possible to connect and articulate said said first whales 21,21 ′ between them, in particular allowing these first whales to pivot relative to one another. Also, the first sheath 50 forms a first junction 51. In addition, thanks to this first sheath 50, said first ribs 21, 21 ′ carry the tent fabric 14.

Similarly, the second whales 22, 22 ' of the first and second umbrella structures 16, 16 ' each have a distal end 22a, 22'a. These distal ends 22a, 22'a are engaged in a second sheath 52. The second ribs can therefore pivot relative to each other and also carry the tent fabric 14 so that they cooperate with the tent fabric . The second sheath 52 forms a second junction 53.

The tent fabric 14 is connected to the first and second umbrella structures 16, 16 ' at the level of the first and second upper hubs 18 , 18', the joints 32 , 32 ' and the distal ends of the first 21, 21 ', second 22, 22 ', third 23.23' and fourth 24.24 ' ribs of each of the two 16.16' umbrella structures .

The figures 3 to 5 illustrate the placing in the deployed position of the foldable tent 10. To do this, the first and second umbrella structures 16, 16 ' are brought successively from their closed position to their open position.

In this nonlimiting example, first the first umbrella structure 16 is brought into the open position and then the second umbrella structure 16 '. First, the user stands next to the foldable tent 10 placed in the folded position and pulls the first cord 46 towards him, using the first grip ring 48. This traction makes it possible to move the first lower hub 20 according to the first direction of movement Y1 and to bring it closer to the first upper hub 18, as illustrated in figure 3 .

The counter whales 26, 27, 28, 29, 30 of the first umbrella structure 16 guide the movement of the first lower hub 20. In parallel with the movement of the first lower hub 20, the counter whales exert a force on the first portions of the whale 34 whales 21, 22, 23, 24, 25 of the first umbrella structure 16, tending to separate them from one another. Said first portions of whale 34, as well as the hinges 38 connecting them to the second portions of whale 36, move away and pivot towards the outside of the first umbrella structure 16.

Insofar as the diameter D1 of the first upper hub 18 is greater than the diameter D2 of the first lower umbrella 20, the spacing of the ribs and the movement of the first lower hub towards the first upper hub is facilitated.

As illustrated by the passage from the figure 3 to the figure 4 , the counter whales jointly cross a plane P passing through the joints 32 between the whales and counter whales and which is perpendicular to the first direction of movement Y1 . The crossing of this plane P by the counter-whales is also called crossing of the hard point. The first lower hub 20 is brought into contact with the first upper hub 18, in a stable position, insofar as the first lower hub 20 can no longer cross the plane P without an effort made by the user. The elongated portion 40 of the first lower hub 20 passes through the orifice 44 of the first upper hub 18 and the bearing portion 42 of the first lower hub 20 projects from the foldable tent 10.

Insofar as the tent fabric 12 is connected to the first upper hub 18, to each of the hinges 38 and to the distal ends of the first 21, second 22, third 23 and fourth 24 ribs, the tent fabric is tensioned during the opening of the first umbrella structure 16. In addition, the tent fabric exerts a tension on said ribs between the first upper hub 18 and said distal ends of each of the ribs.

Consequently, the second portions of whale 36 are automatically pivoted towards their unfolded positrons. The hinges 38 limit this pivoting when the second whale portions 36 are positioned in the continuity of the first whale portions 34, as illustrated by the passage of the figure 3 to the figure 4 . In addition, the tent fabric 14 exerts a force on the second whale portions 36 preventing them from being folded down unintentionally. The second whale portions 36 are therefore brought into the unfolded position automatically when the first umbrella structure 16 is opened and kept in this unfolded position by the tension exerted by the tent fabric 14 on the whales.

In addition, the tensioning of the tent fabric 14 makes it possible to keep the whales of the first curved umbrella structure 16 . The first deployed umbrella structure 16 therefore has a convex shape seen from inside the foldable tent 10.

The first umbrella structure 16 is then placed in the open position in which its ribs are completely separated. Therefore, the foldable tent 10 is placed in an intermediate position illustrated in figure 4 , in which the first umbrella structure 16 is open while the second umbrella structure 16 ' is always closed.

The operator can then open the second umbrella structure 16 '. To do this, you should place yourself on the other side of the foldable tent 10, facing the second upper hub 18 ' and pull the second cord 46' from the second umbrella structure.

The opening of the second umbrella structure 16 ' is similar to the opening of the first umbrella structure 16. In particular, the first and second sheaths 50,52 hingedly connecting the first 21,21' and seconds 22,22 ' ribs allow the relative pivoting of the first 21 and second 22 ribs of the first umbrella structure 16 with respect to the first 21 ' and second 22' ribs of the second umbrella structure 16 '. This allows the positioning of the first and second umbrella structures relative to one another, in order to shape the foldable tent 10.

Furthermore, the tent fabric 14 is also connected to the second upper hub 18 ′ as well as to the hinges 32 ′ and to the distal ends of the ribs of the second umbrella structure 16 ′. In addition, the tent fabric 14 is advantageously shaped so that tension lines 56 are formed on the tent fabric between the hinges 38 ' of the first and second ribs 21', 22 ' of the second umbrella structure 16' and respectively the distal ends 23a, 24a of the third 23 and fourth 24 ribs of the first umbrella structure 16. These tension lines make it possible, in this intermediate position of the foldable tent 10, to maintain the first umbrella structure as well as the plane P inclined with respect to the ground. Also, as illustrated in figure 4 , the third and fourth whales 23, 24 of the first umbrella structure rest on the ground while the first 21 and second 22 whales of the first umbrella structure do not touch the ground.

Thanks to this configuration, when the second umbrella structure 16 ' is brought into the open position, as illustrated by the passage of the figure 4 to the figure 5 , the first 21 ' and second 22' ribs of the second umbrella structure exert an upwardly oriented thrust force on the first 21 and second 22 ribs of the first umbrella structure 16. This effort tends to make the first umbrella structure pivot more , in order to automatically bring it to a final inclination allowing the automatic shaping of the foldable tent 10, as illustrated in figure 5 . In addition, the first umbrella structure 16 supports the second umbrella structure 16 ' and vice versa. The foldable tent 10 is then deployed.

Without departing from the scope of the invention, the second umbrella structure 16 ′ could be opened before the first umbrella structure 16.

In the deployed position of the foldable tent 10, the tent fabric 14 defines an interior volume V. The plane P passing through the articulations of the first umbrella structure is inclined relative to the ground by an angle approximately equal to 45 °. It can be seen that the first and second directions of movement Y1, Y2 are inclined relative to the ground by an angle approximately equal to 45 °. They are also inclined relative to each other by an angle α approximately equal to 90 °. The foldable tent 10 then has a dome shape which can accommodate a camper.

The foldable tent further includes an interior chamber (not shown) disposed under the tent fabric and mounted on the first and second umbrella structures 16, 16 '. Said interior chamber is configured to house the user

The figure 6 is a side view of the foldable tent 10 according to the invention, in which the tent fabric 14 is visible. We see that the tent fabric includes a peripheral edge 14a cooperating with the distal ends 23a, 23'a, 24a, 24'a of the third 23,23 ' and fourth 24,24' ribs of the first and second umbrella structures 16,16 '. In addition, the distal ends 25a, 25'a of the fifth whales 25.25 ' of the first and second umbrella structures 16.16' each cooperate with a cooperating portion 15.15 ' of the tent fabric 14, distinct from said peripheral edge 14a of said tent fabric. Also, the fifth whales spread said tent canvas and increase the interior volume V. Vertical triangular panels 54.54 ' are formed on the tent fabric 14. The fifth whales 25.25' prevent the tent canvas from entering. contact with the head or feet of a user lying in the tent and thus improve their comfort.

According to the invention, the foldable tent 10 can be placed in the deployed position very quickly, only by opening the first and second umbrella structures.

As can be seen on the figure 6 , the tension line 56 formed on the tent fabric 14 between the distal end 23a of the third whale 23 of the first umbrella structure 16 and the hinge 38 ' of the first whale 21' of the second umbrella structure 16 ' includes first, second and third segments 56a, 56b, 56c separate. These three segments are arranged so that an opening, for example for a door, can be made in the tent fabric 14 without the tension line 56 intersecting said door. More specifically, the first segment 56a and the third segment 56c are substantially parallel while the second segment 56b extends substantially horizontally. Another tension line is also formed between the distal end 23a ' of the third whale 23' of the second umbrella structure 16 ' and the hinge 38 of the first whale 21 of the first umbrella structure 16.

The figure 7 is a top view of the foldable tent.

The figure 8 illustrates the foldable tent 10 in the deployed position, the tent fabric 14 being visible. The third 23.23 ' and fourth 24.24' whales of the first and second umbrella structures rest on the ground.

To fold the foldable tent 10, the user must successively place the first 16 and second 16 ' umbrella structures in the closed position. To do this, it is necessary to actuate the bearing portions 42,42 ' of the first and second lower hubs 20,20'. Said bearing portions 42,42 ' pass through the tent fabric 14 so that they are accessible from the outside of the foldable tent 10.

When the user exerts pressure on the bearing portion 42 of the first lower hub 20 from the outside of the foldable tent 10, this pressure is directed in the first direction of movement Y1 . The first lower hub 20 is then moved away from the first upper hub 18 and passes beyond the plane P. The whales 21, 22, 23, 24, 25 of the first umbrella structure 16 are brought together. Under their own weight, and under the weight of the first umbrella structure, the hinges 38 of the whales of said first umbrella structure are moved towards the interior volume V of the foldable tent, while the second portions of whale 36 are pivoted towards the outside of the foldable tent and towards the first upper hub 18. The second portions of whale 36 are therefore folded down automatically when the first umbrella structure is closed. The first umbrella structure 16 is brought into the closed position.

In parallel, the second umbrella structure 16 ' pivots so that the distal ends of its first 21' and second 22 ' ribs are brought closer to the ground.

The same operation is repeated for the second umbrella structure 16 ' which is also brought to the closed position. The foldable tent is then in the folded position, as illustrated in figure 1 and forms a bundle. The foldable tent can then be easily stored in a storage bag.

Without departing from the scope of the invention, the second umbrella structure 16 ′ could be closed before the first umbrella structure 16.
