Description

Domaine technique

[0001] The present invention relates to the field of deployable tents, which have the advantage of being quicker to assemble and disassemble than conventional tents. Technique antérieure

[0002] Among the deployable tents, we know the "pop-up" type tents, such as the one described in document EP1697604, which are particularly quick to set up but whose folding method is sometimes complex. In addition, this type of tent is relatively bulky in the folded position.

[0003] We also know inflatable tents which are fairly quick to set up and take down but which have the disadvantage of requiring either a power source to power the inflator, or inflating the poles using a manual inflator, which can require significant physical effort.

[0004] US2010 / 154282 and US 9598876 describe deployable tents whose frames are equipped with deformable rods. Exposé de l'invention

[0005] An aim of the present invention is to provide a deployable tent allowing quick and easy assembly and disassembly, while being compact in the folded position.

[0006] The invention therefore relates to a deployable tent according to claim 1 comprising a frame and a tent canvas cooperating with the frame, said frame comprising at least one first hoop which comprises at least a first deformable elongate member having a first end portion and a second end portion opposite the first end portion; a second deformable elongate member having a first end portion and a second end portion opposite the first end portion; wherein the first and second deformable elongate elements of the first hoop cooperate with the tent canvas and the first end portions of the first and second deformable elongate elements of the first hoop are arranged end to end, wherein the frame has a folded position and a deployed position, wherein, in the deployed position, the distance between the second end portions of the first and second deformable elongate elements of the first hoop is less than the sum of the lengths of the first and second deformable elongate elements of the first hoop, whereby the bending deformation of the first and second deformable elongate elements of the first hoop increases and then decreases when passing between the deployed position and the folded position.

[0007] Also, thanks to this arrangement, the first hoop, and even more so the frame, has a stable equilibrium position in the deployed position, which means that if one acts on the first hoop in such a way as to deform or move it slightly while the frame is initially in the deployed position, the frame returns to the deployed position after one has stopped acting on the first hoop.

[0008] To bring the frame into the folded position from the deployed position, the user must apply sufficient force to the frame to deform the first arch in bending in order to bring it into an intermediate position of unstable equilibrium, then cross this intermediate position, after which the deformation of the first arch decreases in order to reach another position, different from that in which it was when the frame was in the deployed position.

[0009] Also, the arrangement of the deployable tent according to the invention is such that the flexural deformation of the first and second deformable elongate elements of the first hoop increases then decreases when moving from the deployed position to the folded position.

[0010] We therefore understand that when the frame is in the deployed position, it tends to remain there, unless the user applies sufficient force to deform the first hoop and bring the frame into the folded position.

[0011] In the folded position, the first and second elongate members may be positioned next to each other, substantially parallel to each other so that the length of the first hoop in the folded position is of the order of the length of the largest of the first and second elongate members.

[0012] By "arranged end to end" is meant, within the meaning of the present invention, that the first end portions of the first and second elongate elements are arranged close to each other, being in contact with each other directly or indirectly. For example, the first end portions of the first and second elongate elements may be connected together by a connecting element, or may come directly into contact with each other.

[0013] Preferably, said distance is considered, in the deployed position, between the second ends of the first and second deformable elongate elements of the first hoop, the second ends being opposite the first end portions of the first and second deformable longitudinal elements.

[0014] Preferably, the first and second elongate elements have substantially the same length.

[0015] According to the invention, in the deployed position, the first and second deformable elongate elements of the first hoop exert pressure against each other. The first and second deformable elongate elements are therefore in tension, which gives rigidity to the first hoop.

[0016] According to the invention, the first end portions of the first and second elongate elements exert pressure against each other when the frame is in the deployed position.

[0017] Advantageously, the first and second deformable elongate elements are held together so that, in the folded position, the kinematic connection between the first deformable elongate element and the second deformable elongate element is preferably of the ball joint type. This ball joint type articulation facilitates the folding of the frame and allows the tent to be folded into a very compact volume.

[0018] According to the invention, in the deployed position, the first and second deformable elongate elements of the first hoop are deformed in flexion.

[0019] Preferably, in the deployed position, at least one of the first and second deformable elongate elements of the first hoop has a concavity directed towards the outside of the tent. In other words, the intrados of said at least one of the first and second deformable elongate elements is directed towards the outside of the tent.

[0020] Still preferably, in the deployed position, the first and second deformable elongate elements each have a concavity directed towards the outside of the tent.

[0021] To ensure support between the first and second deformable elongate elements, the deployable tent according to the invention further comprises at least one connection device for receiving the first end portions of the first and second deformable elongate elements of the first hoop.

[0022] The connection device preferably has a dual function, namely the maintenance of the first deformable elongate element relative to the second deformable elongate element on the one hand, and the transmission of forces between the first and second deformable elongate elements on the other hand.

[0023] The connection device may comprise an attached textile part and / or a connection sleeve.

[0024] Preferably, the connecting device is attached to the tent canvas.

[0025] According to a preferred embodiment, the connection device comprises at least one sheath, fixed to the tent canvas, and receiving the first end parts of the first and second deformable elongate elements of the first hoop.

[0026] Preferably, the sheath is sewn to the tent canvas, on its inner face. The sheath preferably has two housings inclined relative to each other, each housing being fixed to the tent canvas and receiving an end portion of one of the first and second deformable elongate elements.

[0027] Advantageously, the connection device is arranged to allow articulation between the first end parts of the first and second deformable elongate elements of the first arch.

[0028] Preferably, the connection device comprises a flexible sleeve engaged with the first end portions of the first and second deformable elongate elements of the first hoop.

[0029] Preferably, the flexible sleeve is engaged in the aforementioned sheath.

[0030] Advantageously, the tent canvas comprises a first housing, for example in the form of a pocket, in which the second end part of the first elongate deformable element is engaged when the tent is erected.

[0031] According to the invention, the tent canvas comprises at least one tensioned zone when the frame is deployed, said tensioned zone cooperating at least with the first end parts of the first and second deformable elongate elements of the first hoop.

[0032] The tension zone helps keep the first arch in the erect position.

[0033] Preferably, the tent fabric has a lower portion connected to the ground, and the tensioned area extends between the lower portion of the tent fabric and the first end portions of the first and second deformable elongate elements of the first pole. By "tensioned area" is meant that the tent fabric is locally tensioned.

[0034] Preferably, the tensioned area is a tension line, i.e. the tensioned area extends substantially in a straight line.

[0035] Preferably, the tent fabric has a plurality of tension zones extending from or between the first end portions of the deformable elongate members, thereby facilitating the retention of the frame in the deployed position.

[0036] According to a preferred embodiment, each of the first and second deformable elongate elements of the first hoop comprises a rod. The rod may be made of fiberglass, aluminum, plastic or wood. According to a preferred embodiment, the first and second deformable elongate elements have substantially the same length.

[0037] An advantage is that, in the folded position, the deployable tent has a generally cylindrical shape whose length corresponds approximately to the length of the deformable elongated elements.

[0038] According to the invention, the first hoop further comprises third and fourth deformable elongate elements arranged end to end, the second and third deformable elongate elements of the first hoop being arranged end to end and cooperating with the tent canvas so as to define a first main vertex of the tent canvas.

[0039] Advantageously, the first and second elongate elements arranged end to end define a first secondary vertex of the tent canvas, while the third and fourth elongate elements arranged end to end define a second secondary vertex of the tent canvas, and the tent according to the invention further comprises at least one reinforcing element fixed to the tent canvas, the reinforcing element comprising a first part connected to the first main vertex, a second part connected to the first secondary panel, and a third part connected to the second secondary vertex. The reinforcing element has the effect of maintaining the distance between the first and second secondary vertices in the deployed position, which makes it possible to reduce the risk of the tent collapsing under its weight when it is deployed. Preferably, the first, second and third parts form a single piece.Advantageously, the reinforcing element consists of a triangular panel, the second part forming one side of said triangular panel. This panel is, for example, a textile panel. More preferably, the other sides of the panel are fixed, for example by sewing, to the tent canvas.

[0040] Advantageously, the tent canvas has a second tension zone extending between the first end portions of the third and fourth deformable elongate elements and a second lower portion of the tent canvas, the latter preferably being fixed to the ground by a second fixing member, such as a sardine.

[0041] Preferably, the tent further comprises a holding device for receiving the second end portions of the second and third deformable elongate elements. This holding device is preferably fixed to the tent canvas, for example an attached sheath fixed to the tent canvas by sewing.

[0042] According to a preferred arrangement, the first and second deformable elongate elements on the one hand, and the third and fourth deformable elongate elements on the other hand, are arranged on either side of a vertical plane passing through the first main vertex.

[0043] According to a preferred embodiment, the frame further comprises a second hoop which comprises at least: a first deformable elongate member having a first end portion and a second end portion opposite the first end portion; a second deformable elongate member having a first end portion and a second end portion opposite the first end portion; the first and second deformable elongate elements of the second hoop cooperate with the tent canvas and the first end portions of the first and second deformable elongate elements of the second hoop are arranged end to end, wherein, in the deployed position, the distance between the second end portions of the first and second deformable elongate elements of the second hoop is less than the sum of the lengths of the first and second deformable elongate elements of the second hoop, whereby the bending deformation of the first and second deformable elongate elements of the second hoop increases and then decreases when passing between the deployed position and the folded position. The second hoop is therefore similar to the first hoop.

[0044] The tent preferably has third and fourth tension zones, similar to the first and second tension zones. The third tension zone extends between the first end portions of the first and second deformable elongate elements of the second pole and a third lower portion of the tent which is connected to the ground via a third fixing member.

[0045] The fourth tension zone extends between the first end portions of the third and fourth deformable elongate elements of the second hoop and a fourth lower portion of the tent canvas which is connected to the ground via a fourth fixing member.

[0046] In addition, the tent canvas has a fifth tension zone which extends between the first end portions of the first and second elongate elements of the first hoop on the one hand, and the first end portions of the first and second elongate elements of the second hoop on the other hand.

[0047] Furthermore, the tent canvas has a sixth tension zone which extends between the first end portions of the third and fourth elongate elements of the first hoop on the one hand, and the first end portions of the third and fourth elongate elements of the second hoop on the other hand.

[0048] Advantageously, the first and second hoops are arranged so that the first, fifth and third tension zones are in continuity with each other. Similarly, the second, sixth and fourth tension zones are in continuity with each other.

[0049] This configuration improves the position retention of the first and second hoops in the deployed position.

[0050] Preferably, the frame is devoid of a rod between the first and second hoops. One advantage is to simplify the structure of the frame. This also makes it possible to lighten the structure and facilitate assembly and disassembly of the frame. The first and second hoops are therefore preferably connected and held together by the tent canvas and not by the frame.

[0051] Advantageously, the tent comprises a first connecting element fixed to the tent canvas near the first end portions of the first and second deformable elongate elements of the first hoop, and at least one ground fixing member attached to the first connecting element.

[0052] Preferably, the tent further comprises a second connecting element fixed to the tent canvas near the first end portions of the first and second deformable elongate elements of the second pole, and the second ground connecting element is connected to the ground fixing member.

[0053] More preferably, the first and second connecting elements form a single piece, and are for example made of a cord.

[0054] Advantageously, in the folded position, the first and second deformable elongate elements are substantially parallel and the length of the deployable tent in the folded position is substantially equal to the length of one of the first and second deformable elongate elements.

[0055] Preferably the tent further comprises an inner chamber which is connected to the frame and / or the tent canvas.

[0056] More preferably, the tent canvas comprises at least one opening forming a door for accessing the interior of the tent, the opening being provided in a portion of the tent canvas which opens between the first and fourth deformable elongate elements. Brève description des dessins

Description détaillée d'un mode de réalisation

[0058] On the figure 1 , an embodiment of a deployable tent is illustrated in perspective 10 in accordance with the present invention. On the figure 1 , we note that the deployable tent 10 is in the deployed position.

[0059] The deployable tent 10 has a skeleton 12, better visible on the figure 3 , as well as a tent canvas 14, cooperating with the framework 12.

[0060] In this example of realization, the frame 12 is arranged inside the tent canvas 14. However, without departing from the scope of the present invention, the tent canvas could be arranged inside the volume defined by the frame. 12.

[0061] As a result, the framework 12, in this example, wear the tent canvas 14. The deployable tent 10 has a back wall 19which, in this example, is part of the tent canvas. Without departing from the scope of the present invention, the back wall may also belong to an optional interior chamber, separate from the tent canvas.

[0062] The skeleton 12 has a first arch 16 and a second hoop 18, similar to the first arch 16. The second hoop 18 is placed at a distance from the first arch 16. As can be seen on the figure 3 , in the deployed position, the first and second hoops 16, 18 extend substantially in two substantially vertical planes.

[0063] Referring now to the figure 2 , we will describe the first arch more precisely 16.

[0064] According to the invention, the first arch 16 comprises a first deformable elongated element 20 having a first end portion20a and a second end part 20b, opposite the first end part 20a.

[0065] The first hoop 16 further comprises a second deformable elongated element 22 having a first end portion 22a, and a second end part 22b opposite the first end part.

[0066] In this example, the first hoop 16 further comprises a third deformable elongated element 24 comprising a first end portion 24a, and a second end part 24b opposite the first end part 24a.

[0067] The first hoop 16 further comprises a fourth deformable elongated element 26 comprising a first end portion 26a and a second end part 26b.

[0068] As can be seen on the figures 1 And 2 , the first and second deformable elongated elements 20, 22 of the first arch 16 cooperate with the tent canvas 14. Similarly, the third and fourth deformable elongated elements 24, 26 of the first arch 16 cooperate with the tent canvas 14.

[0069] In this example, the first, second, third and fourth deformable elongate elements 20,22,24,26 have rods made of fiberglass, aluminum or wood.

[0070] We see that the first end parts 20a, 22a first and second deformable elongated elements 20, 22 of the first arch 16 are arranged end to end, and define a first secondary vertex 25 of the tent canvas when the frame is in the deployed position. Similarly, the first end parts 24a,26a third and fourth deformable elongated elements 24,26 of the first arch are arranged end to end, and define a second secondary vertex 27 of the tent canvas when the frame is in the deployed position.

[0071] In the deployed position, the first and second deformable elongated elements 20, 22, of the first arch 16, are arranged to exert pressure against each other. To do this, in this example, the first end parts 20a, 22a, first and second elongated elements 20, 22, are arranged end to end and are connected together by a connecting device 30, which receives the first end parts of the first and second deformable elongate elements of the first arch.

[0072] In this example, the connecting device 30 includes a sheath 32which is attached to the tent canvas by sewing. This sheath therefore receives the first end parts 20a, 22a first and second elongated elements.

[0073] It is also noted that the connection device 30 is arranged to allow articulation between the first end portions 20a, 22b first and second deformable elongated elements 20, 22 of the first arch 16. As will be explained below, this joint facilitates in particular the operations of deploying and folding the tent.

[0074] In the illustrated embodiment, the connection device further comprises a flexible sleeve 34, in this example, made of plastic, which has two receiving portions 34a, 34b to receive the end parts 20a, 22a first and second deformable elongated elements 20, 22. This soft sleeve 34is deformable, so as to form a flexible articulation, preferably of the ball joint type, between the first and second deformable elongated elements 20, 22. The soft sleeve 34 also allows the first and second deformable elongate elements of the first arch 16, to exert pressure against each other when the frame is in the deployed position.

[0075] As can be seen on the figure 2 , the second and third deformable elongated elements 22, 24, of the first arch 16, are arranged end to end and cooperate with the tent canvas 14, so as to define a main vertex 15 tent canvas 14 of the deployable tent 10. More precisely, the second end parts 22b, 24b second and third deformable elongated elements 22, 24,are arranged end to end and are held together by another connecting device 30, similar to that which connects the first and second deformable elongate elements 20, 22. Likewise, first end parts 24a, 26a third and fourth deformable elongated elements 24, 26 are arranged end to end, and are held together by a connecting device 30.

[0076] Furthermore, the second end part 20b of the first deformable elongated element 20, as well as the second end part 26b of the fourth deformable elongated element 26, are engaged in pockets 40 attached to the tent canvas 14.

[0077] As can be seen on the figure 2 , to improve the hold of the tent canvas 14 at the first arch 16, the deployable tent 10optionally includes loops 42, attached to the tent canvas 14, and cooperating with each of the first, second, third, fourth deformable elongated elements 20, 22, 24, 26.

[0078] Referring to the figure 2 , we note that the distance D1 between the second end parts 20b, 22b, first and second deformable elongated elements 20, 22 of the first arch 16, is less than the sum of the lengths L1 , L2 first and second deformable elongated elements 20b, 22b of the first arch 16.

[0079] In this example, the distance D1 is taken between the end of the first deformable elongate element 20, which is opposite the second end part 20b of said first deformable elongated element 20, and the end of the second deformable elongated element 22which is opposite the first end part 22a of said second deformable elongated element 22.

[0080] In this example, in the deployed position, the first and second deformable elongate elements 20, 22, of the first arch 16, are deformed in bending. They are therefore in tension due to their bending deformation.

[0081] The same applies to the third and fourth deformable elongated elements 24, 26.

[0082] In this example, in the deployed position of the frame, the distance D2 between the second end parts 24b, 26b third and fourth deformable elongated elements 24, 26, of the first arch 16, is less than the sum of the lengths L3, L4 third and fourth deformable elongated elements 24, 26. The third and fourth deformable elongated elements 24, 26are, in the deployed position, deformed in flexion, their concavity being directed towards the outside of the deployable tent.

[0083] In this example, the second hoop 18 also includes a first deformable elongated element 20' having a first end portion 20'a, and a second end part 20'b opposite the first end part 20'a.

[0084] The second hoop 18 further comprises a second deformable elongated element 22' having a first end portion 22'a, and a second end part 22'b, opposite the first end part.

[0085] The first and second deformable elongated elements 20', 22', of the second arch 18, cooperate with the tent canvas 14.

[0086] The first end parts 20'a, 22'a, first and second deformable elongated elements 20', 22', of the second arch 18, are arranged end to end and define a third secondary vertex 25' of the tent when the frame is in the deployed position.

[0087] Like the first arch 16, in the deployed position, the distance between the second end parts 20'b, 22'b first and second deformable elongated elements 20', 22', of the second arch 18, is less than the sum of the lengths L'1, L'2 first and second deformable elongated elements 20', 22' of the second arch 18.

[0088] As we notice on the figure 3 , the second arch 18 also includes third and fourth deformable elongate members, similar to the third and fourth deformable elongate members 24, 26, of the first arch 16.The third and fourth elongated elements are arranged end to end and define a fourth secondary vertex 27' of the tent when the frame is in the deployed position. In this example, in the deployed position, the first, second, third and fourth deformable elongated elements of the second hoop are also in tension due to their bending deformation.

[0089] The second end parts of the second and third deformable elongate elements 22',24' define a second main summit 15' of the tent canvas of the deployable tent 10.

[0090] The deployable tent 10 also comprises connecting devices for receiving the first end portions of the first and second deformable elongate members 20', 22' of the second arch 18. These connection devices, which allow the second arch to be connected 18to the tent canvas 14, are, in this example, identical to those which allow the first arch to be connected 16 to the tent canvas 14, so they will not be described in further detail.

[0091] As understood with the help of the figure 3 , the first and second arches 16, 18, are two elements distinct from each other. In particular, the frame 12 is devoid of connecting elements linking the first and second arches 16, 18 together. In particular, the frame is devoid of a rod connecting the first and second hoops together 16, 18.

[0092] Referring to the figure 1 , we note that, in the deployed position, the tent canvas has several areas under tension.

[0093] The tent canvas 14 has a first tension zone Z1 which cooperates with the first end parts 20a, 22a first and second deformable elongated elements 20, 22 of the first arch 16. This first area of ​​tension Z1 constitutes a line of tension which extends between a lower portion 50 tent canvas 14, and the first end parts 20a, 22a, first and second deformable elongated elements 20, 22 of the first arch 16. This first lower portion 50 is, in this example, fixed to the ground by means of a fixing member 52, in this case a sardine, which is connected to the lower portion 50 by a loop 54.

[0094] The tent canvas also has a second tension zone Z2 which extends between a second lower portion 56of the tent canvas, which is connected to the ground, and the first end parts of the third and fourth deformable elongated elements of the first hoop 16.

[0095] The tent canvas also has third and fourth tension lines Z3, Z4, similar to the first and second tension lines Z1, Z2, which extend between the first end portions of the first, second, third and fourth deformable elongate elements of the second hoop 18, and the third and fourth lower portions 58, 60 of the tent canvas, which are also connected to the ground.

[0096] The first, second, third and fourth lower portions of the tent canvas 14 are located at the four corners of the lower edge of the tent canvas.

[0097] Furthermore, as can be seen on the figure 1 ,the tent canvas also includes a fifth tension zone forming a tension line Z5 which extends between the first end portions 20a, 22a, first and second deformable elongated elements 20, 22 of the first arch 16, and the first end parts 20'a, 22'a first and second deformable elongated elements 20', 22' of the second arch 18. In other words, the fifth tension line runs between the first and third secondary vertices 25,25'.

[0098] Symmetrically, the tent canvas also has a sixth tension zone, forming a tension line Z6 which extends between the first end portions of the third and fourth deformable elongate elements 24, 26 of the first hoop, and the first end parts of the third and fourth deformable elongate elements of the second hoop 18.In other words, the sixth line of tension extends between the second and fourth secondary vertices 27,27'.

[0099] As illustrated in figure 1 , areas of tension Z1 , Z5 And Z3 are arranged in continuity with each other between the first lower portion 50 and the third lower portion 58 of the tent canvas. Similarly, the areas under tension Z2, Z6 And Z4 are arranged in continuity with each other between the second lower portion 56 and the fourth lower portion 58 of the tent canvas. This configuration improves the support of the first, second, third and fourth secondary peaks 25,27,25',27'.

[0100] Referring again to the figure 1 , we note that the deployable tent 10 further comprises a first connecting element 70which is attached to the tent canvas 14, near the first end parts 20a, 22a first and second deformable elongated elements 20, 22 of the first arch 16. In this example, the first connecting element consists of a cord. A fixing member is also provided 72, in this case a sardine, which is connected to the first connecting element 70, so as to tension said connecting element 70.

[0101] The deployable tent 10 further comprises a second connecting element 74 which is connected to the tent canvas 14, near the first end parts 20'a, 22'a first and second deformable elongated elements 20', 22' of the second arch 18.

[0102] In this example, the second connecting element is also made of a cord.

[0103] The second connecting element is connected to the fixing member 72, so as to put the second connecting element under tension.

[0104] In this example, the first and second connecting elements 70,74 form a single piece and are made of a cord.

[0105] The deployable tent 10 comprises, in this example, third and fourth connecting elements (not illustrated here), identical to the first and second connecting elements, and which are connected, respectively, near the first end portions of the third and fourth deformable elongate elements of the first hoop, on the one hand, and near the first end portions of the third and fourth deformable elongate elements of the second hoop, on the other hand.

[0106] In this example, the first, second, third, and fourth deformable elongate elements of the first and second hoops 16, 18,are made up of rods of approximately the same length.

[0107] On the figure 4 , the deployable tent was illustrated 10, in the folded position. As can be seen, the first, second, third, fourth deformable elongated elements of the first and second hoops are substantially parallel, and are arranged side by side, while being surrounded by the tent canvas 14, so that the length of the deployable tent, in the folded position, is substantially equal to, or slightly greater than, the length of the deformable elongate elements. Consequently, once folded, the tent 10 has a very compact configuration and is easily transportable.

[0108] With the help of the figures 5 à 10 , We will now describe the deployment of the deployable tent 10, described previously.

[0109] On the figure 5 ,the shape of the deployable tent has been illustrated, after unfolding the tent canvas 14, so that the back wall 19 lie flat on the ground S. In this initial configuration we understand that the frame is folded, the hoops 16, 18 resting on the ground.

[0110] In this example of implementation, the first, second, third and fourth lower portions are first fixed 50, 56, 58, 60 of the tent canvas to the ground. The tent canvas is therefore fixed to the ground, so that its lower part has a substantially rectangular shape. Then, the user deploys the frame by pulling the first end parts of the deformable elongated elements towards him. In this example, illustrated in figures 6 et 7 , the user exerts traction on the first and second connecting elements 70, 74.This tensile movement has the effect of deforming, by bending, the deformable elongated elements, so that their concavity is turned towards the outside of the tent, as illustrated.

[0111] In the traction movement exerted by the user, the first and second deformable elongate elements pass in this example from an undeformed state, that is to say that they are substantially rectilinear, to a deformed state in bending, illustrated in figures 8 et 9 , in which their concavity is directed towards the outside of the tent.

[0112] As understood with the help of the figure 9 , when passing from the undeformed state (folded frame) to the deformed state (deployed frame), the first and second elongate elements deform in bending so that their bending deformation increases until the first end portions of the first and second elongate elements cross a geometric straight lineX connecting the second end portions of the first and second elongate members, after which their bending deformation decreases until the first end portions have reached a final deployed position, in which they are retained by the tent canvas. It is therefore understood that the bending deformation of the first and second deformable elongate members 20, 22, of the first arch 16, increases then decreases, when moving from the folded position to the deployed position.

[0113] Similarly, the bending deformation of the first and second deformable longitudinal elements 20,22 of the first arch 18increases and then decreases, when moving from the deployed position to the folded position. This means that, in the deployed position, the first and second deformable elongate elements cannot return to their initial state, since, to do this, it is necessary to further deform the first and second deformable elongate elements in flexion so that they can cross the geometric line X aforementioned, which requires user intervention.

[0114] We therefore understand that the frame is held in its deployed position by the tent canvas 14 which keeps the elongated elements in tension, which gives rigidity to the poles. At the same time, the tension lines help to improve the positioning of the poles. Also, the frame has a stable position, as a result of which the deployable tent, in the deployed position, also has a stable position.

[0115] As explained above, the frame allows for easy deployment while being compact in the folded position.

[0116] On the figure 11 , a variant has been illustrated in which the deployable tent further comprises a reinforcing element 80.

[0117] The reinforcing element 80 includes a first part 82 connected to the first main summit 15, a second part 84 connected to the first secondary summit 25 and a third part 86 connected to the second secondary summit 27. In this example, the first, second and third parts constitute a single element forming a triangular panel. This panel is, for example, a flexible textile panel.

[0118] The triangular panel has two sides 80a, 80b attached to the tent canvas, for example by sewing, and a third side 80c, which can be arched or straight.

[0119] As we understand on the figure 11 , the panel extends in a substantially vertical plane.

[0120] The tent may have several reinforcement elements of the same type.

[0121] The reinforcing element has the effect of maintaining the distance between the first and second secondary peaks in the deployed position, thereby reducing the risk of the tent collapsing under its own weight when deployed.
