Description

Title of the invention: Deployable and foldable shelter structure and corresponding method. FIELD OF THE INVENTION

[0001] The present invention relates generally to a deployable and foldable shelter structure, for example to form a pool shelter or a temporary office, or a dwelling. EARLIER ART

[0002] The state of the art is known for deployable and foldable shelter structures using an electric motor.

[0003] However, known structures present several drawbacks. In particular, the energy consumed by the motor for deploying the structure can be significant. Some structures also involve cumbersome interventions for the user during deployment.

[0004] The present invention aims to propose a new deployable and foldable shelter structure and a corresponding new method to overcome at least partially one or more of the problems described above. Summary of the invention

[0005] For this purpose, the invention relates to a shelter structure, such as a temporary office or pool cover, deployable and foldable comprising: - a base; - a ceiling comprising a ceiling frame including stringers connected to each other by crossbeams; - a wall panel, called the front wall panel; - a deployment command system; characterized in that the front wall panel has a lower part hinged at the base and an upper part equipped with glides mounted to slide along parallel elements (to each other) of the ceiling frame, the upper part of the front wall panel being mounted hinged to said glides; The deployment command system is configured to: - order a lifting initiation system, to move the ceiling frame away from the base by a given distance, called the initiation distance, so that the front wall panel moves from a position substantially parallel to the ceiling frame to a position inclined relative to the ceiling frame; - to control the movement of the front wall pads in the direction of straightening the wall so that the front wall is straightened results in a continued separation of the ceiling frame from the base until the front wall extends substantially perpendicular to the ceiling frame.

[0006] The initial deployment distance is less than the final deployment distance obtained at the end of the structure's full deployment. The position of the front wall panel substantially parallel to the ceiling frame corresponds to the fully retracted state of the structure. The inclined position of the front wall panel relative to the ceiling frame corresponds to a partially deployed, i.e., intermediate, state of the structure.

[0007] The control of the lifting initiation system also causes, simultaneously with the separation of the ceiling frame from the base, the sliding of the wall-wall pads to allow the ceiling to separate from the base. These pads are connected to each other by the wall-wall, so that, once the lifting initiation system is deployed, the deployment control system commands the continued movement of the front wall-wall pads. At the end of deployment, the front wall-wall extends perpendicularly, preferably vertically, to the ceiling frame, between the base and the ceiling frame, preferably along a longitudinal member of the ceiling frame. The ceiling frame is then separated from the base by a distance corresponding to the full deployment distance of the structure.

[0008] Such a design of the structure makes it possible to deploy the structure reliably and with a limited amount of energy to obtain a usable habitable volume.

[0009] The structure can be used to form a habitable volume for a work or residential application, garden shed, or pool enclosure.

[0010] Preferably, as explained below, the structure includes a so-called rear wall.

[0011] The arrangement of the wall panel or each wall panel with the ceiling frame and the base, using the pads and joints, thus forms a lifting pursuit system which allows the ceiling frame to be moved further apart from the base, by straightening the wall panel or each wall panel controlled by the deployment control system.

[0012] According to one embodiment, for the front or rear wall panel or panels, the upper end portion of the wall panel is mounted to slide, via glides, along two cross members of the ceiling frame, the upper end portion of the wall panel also being mounted to pivot about an axis, called the upper pivot axis, of the glides, orthogonal to the cross members to allow pivoting of the wall panel during the sliding movement of the wall panel along said cross members of the ceiling frame, and the lower end portion of the wall panel is also mounted to hinge at the base about an axis, called the lower pivot axis, parallel to the upper pivot axis.

[0013] The upper end part of the wall panel can slide and pivot along corresponding cross members of the ceiling frame, while the lower end part of the wall panel pivots relative to the base.

[0014] The structure may also include one or more of the following features taken in any technically permissible combination.

[0015] According to one embodiment, the lifting initiation system comprises a portion, called the front lifting initiation system, located on one side of the ceiling frame, preferably along one of the ceiling frame's longitudinal members, and another portion, called the rear lifting initiation system, located on the opposite side, preferably along the opposite longitudinal member of the ceiling frame. Advantageously, the front lifting initiation system and the rear lifting initiation system each comprise a first initiation device, and preferably a second initiation device, as described below.

[0016] According to one embodiment, the lifting launch system is supported by the ceiling frame such that, in the fully deployed state of the structure, the lifting launch system is raised away from the base (and the ground). In other words, the lifting launch system is lifted relative to the ground or the base. There is then no longer any contact between the base or the ground and the lifting launch system.

[0017] According to one embodiment, the lifting initiation system comprises a first initiation device having two arms articulated to each other, in the shape of an X, Y or V, the upper ends of the X, Y or V being connected to the ceiling frame, preferably to a stringer of the ceiling frame, the upper ends being movable between: a position separated from each other in which the first priming device is folded, and a position close to each other in which the first priming device is erected (deployed) orthogonally to the ceiling frame.

[0018] This extended position allows the first device to be held against the ceiling frame, for example, to conceal it or to allow the ceiling frame to be brought as close as possible to the base when the structure is folded. This extended position allows the ceiling frame to be raised, in particular relative to the base, with its lower end being moved away from the ceiling frame by a distance corresponding approximately to the length of the arm.

[0019] According to one embodiment, the lifting initiation system comprises a second initiation device having two arms articulated to each other, in the shape of an X, Y or V, the upper ends of the X, Y or V being connected to the ceiling frame, preferably to a stringer of the ceiling frame; the upper ends being movable between: a position separated from each other in which the second priming device is folded, and a position close to each other in which the second priming device is erected orthogonally to the ceiling frame (deployed); the longest arm of the first priming device being shorter than the arms, or the longest arm, of the second priming device.

[0020] The extended position allows the second device to be held against the ceiling frame, for example to conceal it, or allows the ceiling frame to be brought as close as possible to the base when the structure is folded. The extended position allows the ceiling frame to continue to be raised, particularly relative to the base, with each lower end positioned away from the ceiling frame by a distance corresponding approximately to the length of the relevant arm.

[0021] According to one embodiment, the structure deployment control system is configured with the lifting initiation system so that, during the command of the lifting initiation system in the direction of a deployment of the structure, the first initiation device straightens, and (during the straightening) pushes on the second initiation device in the direction of bringing the ends of the second initiation device closer together.

[0022] Such a design makes it easier to straighten or deploy the second device. The thrust is exerted towards one end of the second initiating device, which is mounted hinged but fixed, i.e., without sliding, relative to the ceiling frame.

[0023] According to one embodiment, at least a part of the lifting initiation system is mounted articulated on a sliding skid system mounted along at least one element of the ceiling frame orthogonal to the elements along which the wall panel is mounted sliding.

[0024] According to a particular aspect, at least part of the ends of the priming devices are carried by slide-mounted pads along a frame element orthogonal to the frame elements along which the front or rear wall(s) are slidably mounted.

[0025] According to one embodiment, one end of the first priming device is slidably connected to one end of the second device, preferably fixed to the same pad by being articulated to said pad. The other end of the first priming device is articulated to a pad separate from said pad, which connects said end of the first priming device and said end of the second device.

[0026] According to one embodiment, the upper end of the second priming device furthest from the first priming device is articulated to the frame ceiling, without freedom of sliding relative to the ceiling frame, by connecting said end to a fixed part of the ceiling frame.

[0027] According to one embodiment, the structure includes an activatable / deactivatable immobilization system for the ceiling frame relative to the base, configured such that, in the activated state of the immobilization system, the command of the lifting initiation system by the deployment control system causes the entire ceiling frame and base to be lifted (relative to the ground), the structure being supported on the ground by the lower part of the lifting initiation system.

[0028] According to one embodiment, the lower part of the lifting initiation system is provided with rolling elements and the structure includes a motorization system enabling the movement of the structure on the ground to be controlled by rolling the structure in support on said rolling elements.

[0029] According to one embodiment, the structure comprises two stabilization systems arranged along two opposite sides of the ceiling frame (namely the sides at which side walls - also called gables - are able to be deployed), which are perpendicular to the side along which said front wall extends in the upright state, and which are configured to, when the ceiling frame is moved away from the base, maintain a displacement of the ceiling frame parallel to itself, and in a direction orthogonal to the plane in which said ceiling frame extends.

[0030] According to one embodiment, each stabilization system comprises a stabilization device having two X-shaped arms, the upper ends of the X being connected to the ceiling frame, preferably to a cross member of the ceiling frame; the upper ends being movable between: - a position separated from each other in which the stabilizing device is folded against the ceiling frame, and - a position close to each other in which the stabilization device is erected orthogonally to the ceiling frame (deployed).

[0031] The term "close position" means a position less spread out than that resulting from the folding position of the stabilizing device, but for which the upper ends remain spread out.

[0032] The stabilization system thus allows the ceiling frame to be lifted, in particular relative to the base. According to a particular aspect, each arm of the stabilization system has a fixed articulated end and an articulated end that slides relative to the ceiling frame, the base, or the floor.

[0033] According to one embodiment, the structure comprises at least one side wall and a side wall deployment system configured to move the side wall from a position substantially parallel to the ceiling frame in the folded state of the structure, in an upright position orthogonal to the ceiling frame in the deployed state of the structure.

[0034] According to one embodiment, the side wall deployment system comprises: - a push system, such as a jack or a spring, allowing the side wall to be pushed to move it from the substantially parallel position to the ceiling frame, to the upright position, and preferably to hold the side wall against a rail of the wall; - preferably, a braking system to prevent the side panel from moving from its position substantially parallel to the ceiling frame to its upright position. The braking system also allows the side panel to be returned to a position substantially parallel to the ceiling frame.

[0035] According to one embodiment, the side wall deployment system includes a roller system carried by the side wall and a guide rail carried by the wall, the guide rail being configured to receive the roller system and guide the straightening of the side wall as it passes from the substantially parallel position to the ceiling frame to the straightened position.

[0036] According to one embodiment, the upper part of the side wall is mounted to slide along an element of the ceiling frame orthogonal to the elements along which the wall is mounted to slide.

[0037] Advantageously, the wall or each wall is equipped with a guide rail arranged along at least one end post of the wall, so that in the upright state, a roller of a side wall can be inserted into said guide rail to allow the movement of the side wall to be guided when deployed into the upright position.

[0038] According to one embodiment, the ceiling frame element along which the side wall is mounted to slide has an opening allowing the front part of the side wall to drop down for guidance along a rail of the corresponding wall wall in which a roller of the side wall is able to engage during its straightening controlled by the side wall deployment system.

[0039] According to one embodiment, the ceiling frame includes intermediate cross members, which are parallel to said cross members, called end cross members, of the ceiling frame, and along which are mounted sliding the glides which equip the wall panel.

[0040] According to one embodiment, the structure includes a return system, such as a spring or a jack, configured to allow pushing on the upper part of the corresponding wall panel in the direction of a repositioning of the wall panel parallel to the ceiling frame when moving from the deployed position to the folded position of the structure.

[0041] A motor of the deployment control system can be controlled in such a way as to control or brake this movement by limiting the unwinding of the cable of the control system to control the movement of the wall panel pushed by the return system, when passing from the deployed position to the folded position of the structure.

[0042] According to one embodiment, the deployment control system comprises: - a cable and pulley system, which connects the wall wall pads and pads to which the lifting initiation system is connected, said lifting initiation system pads being mounted to slide along element(s) of the ceiling frame which are orthogonal to the ceiling frame elements along which the wall wall pads are mounted to slide; - a winch to which the cable is attached; - preferably, an electric motorization system to drive the winch in the direction of winding or unwinding the cable.

[0043] The winch is capable of being driven in rotation in one direction for winding the cable and in the opposite direction for unwinding the cable.

[0044] According to one embodiment, the base comprises at least one, preferably two, series of plates, preferably suitable for being fixed to the floor, the plates of the or each series of plates being arranged parallel to an element, preferably a stringer, of the ceiling frame so as to be arranged preferably in line with said element, the wall wall preferably comprising uprights whose lower ends are articulated to said plates.

[0045] When the structure comprises a front wall and a rear wall, and the base comprises plates, the plates comprise two sets of plates: one set of plates to which the lower part of the front wall is hinged and arranged parallel to an element, preferably a longitudinal member, of the ceiling frame located on the front side of the structure, and one set of plates to which the lower part of the rear wall is hinged and arranged parallel to an element, preferably a longitudinal member, of the frame preferably located on the rear side of the structure. The two sets of plates are arranged parallel to each other. The plates in the same set are aligned and spaced apart from each other.

[0046] Advantageously, the wall panel hinged to the plates of a series comprises for each plate a metal piece fixed to a post of the wall panel connected by a hinge axis to the plate.

[0047] According to one embodiment, the structure also comprises a so-called rear wall, opposite the front wall in the upright state; the rear wall having a lower portion hinged at the base (on a side of the base opposite the side of the base along which the front wall is hinged) and an upper portion equipped with sliding mounted glides (in the opposite direction to the glides of the front wall panel) along parallel elements (to each other) of the ceiling frame, the rear wall panel being hinged to said glides; the deployment control system is also configured so that, when the ceiling frame is moved away from the base by the lifting initiation system, the rear wall panel moves from a position substantially parallel to the ceiling frame to a position inclined relative to the ceiling frame (in the opposite direction to the front wall panel); the deployment control system is also configured to control the movement of the rear wall pads in the direction of a straightening of the rear wall so that the straightening of the rear wall causes a continuation of the separation of the ceiling frame from the base, until the rear wall extends substantially perpendicularly to the ceiling frame.

[0048] At the end of the deployment of the structure, the front wall panel extends perpendicularly, preferably vertically, to the ceiling frame, between the base and the ceiling frame, preferably along a stringer of the ceiling frame opposite the stringer along which the front wall panel extends.

[0049] A method for deploying a shelter structure, such as a temporary office or pool cover, conforming to any of the preceding embodiments, is also proposed, in which the method comprises the following steps: - controlling a lifting initiation system, to move the ceiling frame away from the base by a given distance, called the initiation distance, so that the front wall panel moves from a position substantially parallel to the ceiling frame to a position inclined relative to the ceiling frame; - to control the movement of the front wall panel pads in the direction of straightening the wall panel.

[0050] According to one embodiment, in the deployed state of the structure, the load-bearing elements of the structure are located along the peripheral contour of the ceiling frame, between the ceiling frame and the base.

[0051] In particular, a structural design in which the load-bearing or supporting elements are formed by X-shaped lateral devices and by the front or rear wall(s), and which support a ceiling frame, makes it possible to do without supports or posts inside the user space defined by the structure.

[0052] As a result, the interior volume is freed up as soon as the structure is deployed so that the user can use the entire floor area defined by the interior of the structure.

[0053] Once the deployment is complete, the structural (i.e. load-bearing) elements of the structure are located in the periphery of the structure, i.e. along the sides of the frame of ceiling (or base), within the footprint of the ceiling frame (or base), in top view. Thus, once the structure is deployed, the load-bearing elements do not extend, in top view, beyond the ceiling frame (or base). In particular, the wall panels transition from a folded configuration parallel (horizontal) to the ceiling frame to a deployed (vertical) configuration in which each wall panel extends between the ceiling frame and the base, substantially perpendicular to said ceiling frame and to the base, and along one side of the ceiling frame and the corresponding side of the base.

[0054] The peripheral distribution of the load-bearing elements in the deployed state allows a significant internal volume to be freed up, which is accessible to the user without constraint and safely.

[0055] Before deployment, the structure is in a folded configuration in which it is contained within a minimum volume (minimum footprint) to facilitate its transport and handling. The limited thickness (height) of the structure in the folded position facilitates its transport and also allows for visual discretion of the structure when it is not in use.

[0056] According to one embodiment, the structure is movable on the ground, with or without a ground foundation. The structure can be placed on a concrete slab, or foundation screws or concrete slabs can be used, depending on the soil conditions and available options.

[0057] It can be provided that elements of the structure, such as the X and / or Y (or V) lifting initiation devices, or elements added to the structure, are equipped with casters and / or motorized wheels allowing the structure to be moved on the ground in the folded state to move it to a given position on the ground.

[0058] For ground movement of the structure, the ceiling frame and the base are held relative to each other in the folded configuration. The ceiling frame can thus be held fixed relative to the base by a spacing locking system, so that the actuation of the lifting devices results in the entire ceiling frame and base being lifted relative to the ground, and not in one being separated from the other.

[0059] The spacing locking system may include an electromagnetic system, such as an electromagnetic suction cup, or a mechanical locking axis system to prevent the movement of a pad from at least the front wall, relative to the ceiling cross members, and in particular to prevent the sliding of the pad along the cross member along which the pad is mounted to slide.

[0060] According to one embodiment, the ceiling frame is provided with intermediate crossbars and infill elements for the inner surface of the frame, such as panels that extend between inner (intermediate) crossbars or between An internal cross member and a peripheral element (cross member or external frame member) form, at least partially, a rigid platform. This platform can serve as a roof and is capable of supporting a given weight. Such a platform allows for the application of thermal insulation, or for supporting service components such as heat pumps and / or creating a green roof or other structural elements.

[0061] The invention also relates to a corresponding deployment method.

[0062] A deployable and retractable shelter structure is also proposed, comprising a base, a ceiling frame, a front wall panel, and a deployment control system. The front wall panel has a lower portion hinged to the base and an upper portion with glides that slide along elements of the ceiling frame. The control system allows the ceiling frame to be moved away from the base to initiate the deployment of the structure, and then continues to straighten the front wall panel until it is substantially perpendicular to the ceiling frame. The invention also relates to a corresponding deployment method. Brief description of the drawings

[0086] Embodiments are described below with reference to the accompanying drawings. Similar numbers refer to similar features in all drawings. However, the invention can be implemented in many different forms and should not be construed as being limited to the embodiments shown here. The scope of the invention is defined by the accompanying claims.

[0087] A reference throughout the specification to "an embodiment" means that a particular feature, structure, or characteristic described in relation to an embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrase "in an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0088] With reference to the figures, a shelter structure 1 is thus proposed, such as a temporary office or pool cover, or a dwelling, which can be deployed and folded. In its deployed state, the shelter structure 1 forms a volumetric structure that delimits a usable interior volume.

[0089] When it is mentioned that an element of the structure is horizontal, vertical, lower or upper, this refers to a state of the structure in use configuration (folded or deployed state), i.e. whose base is supported on a horizontal ground.

[0090] The structure, viewed from above, has four sides: two opposite sides, referred to as front and rear, and two opposite lateral sides, perpendicular to the front and rear sides. At least one wall panel is hinged along an axis parallel to the direction of the front or rear side and extends along that front or rear side when deployed. Preferably, there is one wall panel for each of the front and rear sides. A stabilizing device extends along each lateral side. As detailed below, in the deployed state of the structure, as illustrated in the figures, the front and rear sides correspond to the longitudinal sides of the structure.

[0091] Base and ceiling

[0092] The structure comprises a base 11 and a ceiling 12 which extend parallel to each other.

[0093] The base 11 is intended to be placed, possibly fixed, on a floor. The floor may be the bottom of a recessed area so that, in the folded state of the structure, the ceiling 12 is flush with the area around the shelter structure.

[0094] The ceiling 12 includes a ceiling frame 120 which includes stringers 121 connected to each other by crossbeams 122. In the description, stringers are designated as the elements of the frame along which the wall panels 8, 8' (shown below) extend in the deployed state, and the crossbeams are the other elements of the frame which connect said stringers together, and along which side panels, called gables 5, 5', can extend in the deployed state.

[0095] According to one embodiment and as illustrated in the figures, the ceiling frame 120 also includes intermediate cross members 123 which extend parallel to the end cross members 122 and between said end cross members 122, connecting the stringers 121 together.

[0096] In one embodiment, and as illustrated in the figures, the ceiling also includes rigid panels 124 that close off the interior space delimited by the ceiling frame. The rigid panels 124 preferably extend between intermediate crossbeams 123. In one embodiment, the entire assembly of intermediate crossbeams 12 and panels 124 is covered with an insulating element, such as a sandwich panel.

[0097] According to one embodiment of the invention, the ceiling 12 is rigid. The ceiling can be provided to support a load of at least 1000 kg, preferably up to 10,000 kg.

[0098] According to one embodiment, and as illustrated in Figures 1 to 7, the base 11 comprises a base frame 110 which includes longitudinal members 111 connected to each other by cross members 112.

[0099] Alternatively, the base 11 may be provided in various solid or hollow forms. In particular, and as illustrated in Figures 11 to 18, the base frame may be replaced by plates 111A arranged along the front or rear side to allow the corresponding front or rear wall panel to be articulated on said plates. As illustrated more particularly in [Fig. 17] and [Fig. 18], each plate may include a hinge system forming the articulation axis 118 to which a wall panel stud M8 is attached. The plate may be provided to cooperate with a part 99 fixed to the floor. The plate may cooperate with the part 99 by interlocking, in order to provide a foothold on the floor to absorb the forces during the deployment of the structure.

[0100] In other words, the base can be made in the form of a plurality of plates located directly above one or more corresponding stringers of the ceiling frame, and distributed along the front and / or rear side of the structure (longitudinal side in the illustrated examples). Preferably, each plate located on a front or rear side of the structure is positioned at the level of an M8 stud of the wall panel that is hinged to this plate. These plates can be fixed to the floor by anchors. Making the base in the form of plates reduces the cost of the structure and provides good force distribution during the deployment of the structure.

[0101] Front and rear wall panels 8, 8'

[0102] The structure includes at least one front wall 8 which, in the erected state, extends along a stringer 121 of the ceiling frame. The stringer 121 defines, together with the part 111 ([Fig.5]) or 111A ([Fig.13]) of the corresponding base 11 located directly above the stringer 121, a front face of the structure which is at least partially closed in the erected state of the front wall 8, as illustrated for example in [Fig.6].

[0103] Preferably, and as in the example illustrated in the figures, two wall panels 8, 8' are provided, referred to as front wall panel 8 and rear wall panel 8'. It is possible to consider that the structure includes a front wall panel 8 but no rear wall panel, for example for use as a veranda.

[0104] Advantageously, at least one of the wall panels 8, 8' front or rear has an opening or a hinge, such as a door and / or window.

[0105] When characteristics of the front wall 8 are mentioned below, these characteristics may also apply to the other wall 8'. Conversely, when characteristics are described for both walls 8 and 8', one may stipulate that these characteristics apply only to one of the wall panels, particularly in the absence of the other wall panel.

[0106] The front and rear wall panels 8' are hinged to the base 11 by hinges 118. The hinges 118 allow the wall panels 8, 8' to pivot about an axis parallel to the axis of a stringer 121 of the ceiling frame. For each wall panel 8, 8', the hinges 118 can, as in the example illustrated in the figures, be distributed along the part 111 or 111A (called front or rear) of the base 11 which, together with the corresponding stringer of the ceiling frame, defines the face (front or rear) of the structure that the corresponding wall panel 8, 8' at least partially closes in its upright configuration.

[0107] The front and rear wall panels 8' are also hinged to the ceiling 12, in particular along ceiling crossbeams 123, by means of joints 128. The joints 128 are supported by glides P128 mounted to slide parallel to crossbeams of the ceiling frame. In particular, the glides P128 are supported by crossbeams of the ceiling frame 120 and mounted to slide along said crossbeams, preferably intermediate crossbeams 123 that extend parallel to the end crossbeams 122, and between said end crossbeams 122.

[0108] In a preferred aspect, the base 11 has, on the front and / or rear side of the structure 1, i.e., along said portion 111 or 11 IA of the base 11, reinforcing and sealing folds 119 against which the front and rear wall panels 8, 8' can abut in the deployed state of said front and rear wall panels 8, 8'. As mentioned above, in an embodiment illustrated, for example, in Figures 10 to 16, the base 11 comprises plates 11 IA located at the uprights (also called posts) of the front or rear wall panel, preferably with inserts fixed in the ground. The plates 111A can be associated with the folds 119 to improve sealing when the structure is folded.

[0109] As detailed below and in connection with [Fig. 8], for the deployment (straightening) of the wall panels, the structure includes a control system SC28 configured to move the corresponding wall panel 8 sliders P128. Two sliders P128 are shown in [Fig. 8], but the SC28 control system is adaptable for a larger number of sliders. According to one embodiment and as detailed below, the SC28 control system includes a set of pulleys comprising pulleys 828 carried by the sliders P128 and pulleys 824 carried by the ceiling frame 120, and a cable 290 connecting the pulleys. The SC28 control system also includes a winch T28, preferably motorized by an M28 motor, to which the cable 290 is attached to allow the winding and unwinding of the cable 290 and thus the movement of the pads P128 along the crossbeams 123 of the ceiling frame 120.

[0110] The M28 motor can be a motor powered by an electrical power source or possibly hydraulic or pneumatic.

[0111] It is also possible to provide for manual operation of the T28 winch with a crank system to operate the T28 winch which can be used in the absence of an engine or when the engine is present but malfunctioning.

[0112] According to one embodiment and as detailed below, the SC28 control system is also configured to move slide-mounted skates P21 and P2122 along a stringer 121 of the ceiling frame 120, and to which are connected the deployment initiation devices 21, 22 shown below.

[0113] The SC28 control system includes for this purpose pulleys (not shown) which are carried by at least part of said pads P21, P2122 and through which the cable 290 passes to allow, with the help of the winch T28, the movement of said pads P21, P2122 to be controlled along the corresponding longitudinal member 121 of the ceiling frame 120. Additional return pulleys may be provided depending on the path of the cable 290.

[0114] In the illustrated examples, each frame is rectangular. When the frame is square, it is understood that the stringers and crossbeams are frame elements of the same length. It is also understood that the description given here for an example where the wall panels 8, 8' extend, in the upright state, along frame elements 12 that are longer than the frame elements 12 along which the side panels 5, 5' shown below extend, also applies to a configuration where the wall panels 8, 8' would extend, in the upright state, along frame elements 12 that are smaller (i.e., shorter) than the frame elements along which the side panels 5, 5' would extend.

[0115] As mentioned above, the opposite sides of the structure along which the front wall 8 and rear wall 8' extend respectively in the upright state are called the front side and rear side, respectively. The other opposite sides of the structure are called the lateral sides and are the sides along which the stabilizing devices 3, described below, extend. In the example shown in the figures and as explained below, the stabilizing devices 3 comprise, for each lateral side of the structure, two hinged X-shaped stabilizing devices as detailed below. Alternatively, for each lateral side, the stabilizing device 3 may comprise a single hinged X-shaped stabilizing device.

[0116] The deployment support devices 3 form a stabilization system which, during the deployment and retraction of the structure 1, maintains parallelism between the base 11 and the ceiling 12 relative to each other, and keeps the ceiling 12 plumb relative to the base 11, i.e., to prevent inclination and / or an offset in the horizontal plane (when structure 1 is on a horizontal floor) of the ceiling 12 relative to the base 11.

[0117] The wall panel 8 is arranged with the base 11 and the ceiling 12 so that, in the deployed (upright) position, it extends perpendicularly to the plane (medium plane) in which the base 11 extends and perpendicularly to the plane in which the ceiling frame 120 extends. The wall panel 8 extends in the folded position in a position (approximately) parallel to the plane (medium plane) in which the base 11 extends and to the plane (medium plane) in which the ceiling frame 120 extends.

[0118] In other words, the wall panel 8, in its folded position, has an inner face facing the base 11 (which, in its deployed position, is oriented towards the interior of the structure 1), and an opposite outer face facing the ceiling frame 120 (which, in its deployed position, is oriented towards the exterior of the structure 1). In its deployed position, the inner face is oriented towards the interior of the structure 1, and the outer face is oriented towards the exterior of the structure 1.

[0119] Deployment system

[0120] A deployment system is arranged to allow the deployment of the structure and in particular the lifting of the ceiling 12 relative to the base 11. The deployment system also allows conversely the structure to be folded back to bring it into a less bulky configuration, in particular by bringing the ceiling 12 closer to the base 11.

[0121] The deployment system includes a lifting initiation system S2 and a lifting pursuit system S8 shown below.

[0122] The machine also includes an SC28 control system for the deployment system, an example of which is illustrated in [Fig. 8]. The control system (detailed below) can be motorized and / or manual. In particular, in the event of a motor failure, the control system can be activated manually, for example, using a hand crank connected to a winch.

[0123] Lifting priming system

[0124] In the folded state of the structure, the base 11 and the ceiling 12 are in a position of less separation or are in contact, compared with the separation of the base 11 and the ceiling 12 obtained at the end of deployment using the lifting system.

[0125] The lifting system includes, preferably for each of the two front and rear sides of the shelter structure 1, a lifting initiation system S2 configured to allow the ceiling 12 to be moved away from the base 11 by a given distance, which remains less than the final separation distance between the ceiling frame and the base obtained at the end of the structure's deployment.

[0126] As detailed below, the initial lifting (or spreading) of the ceiling frame 120 relative to the base 11 allows for the initial pivoting of the wall front wall 8' and / or rear wall 8', and thus to facilitate the continuation of their straightening by the S8 system of control of movement of the P128 pads to which are linked the corresponding wall(s).

[0127] The lifting initiation system S2 comprises, for each of two opposite sides of the structure, referred to as the front and rear sides, a Y (or V) device 21 and an X device 22. It should be noted that the example illustrated in the figures is for a Y, but a V can be provided. The upper part of a Y can be considered as forming a V, and a V device can include a branch of the V that extends beyond the tip of the V, thus forming a Y device. Thus, the description given below for a Y can be applied to a V. A Y device is, however, preferred because, compared to a V device, it reduces the energy required to initiate the separation of the ceiling from the base.

[0128] The Y (or V) structure comprises two arms articulated together at their articulation (i.e. at the tip of the V), and the X structure comprises two arms articulated together at the intersection of the two arms.

[0129] Y-shaped lifting initiation device

[0130] According to one embodiment and as illustrated more particularly in [Fig.9B], the Y-shaped lifting initiation device 21 comprises two arms 211, 212 in the general shape of a V. The two arms 211, 212 are articulated with each other, and each has an upper end 211 A, 212A connected to a stringer 121 of the ceiling frame 120 by means of a slider P21, P2122 mounted to slide along said stringer 121.

[0131] The upper end 211 A, 212A of each arm 211, 212 is thus mounted to slide along the corresponding longitudinal member (frame element) of the ceiling frame 120.

[0132] The SC28 control system allows the sliders P21, P2122 to bring the ends 21 IA, 212A closer together and thus tighten the arms of the Y so that the foot of the Y comes to rest by its lower end 21 IB against the base 11, for example an element of the base frame 110 (in the case where it is not planned to be able to move the whole structure on the ground in the folded state of the ceiling frame and the base frame), or against a floor element preferably located outside the base 11, preferably a floor on which the base 11 rests.

[0133] The continued tightening of the Y-arms causes the arms 211 and 212 to straighten, thus separating the ceiling frame 120 from the base frame 11. Simultaneously with the lifting initiation device 21 bearing on the floor or base 11, which causes 12 to separate from 11, the X-shaped device(s) of the stabilization system 3 extend (straighten) due to the separation between the ceiling 11 and the base 12, just as the wall 8 continues to straighten. pivoting upwards thanks to their articulation at the base 11 and sliding along cross members of the ceiling frame 120 towards the corresponding stringer 121 of the corresponding ceiling frame 120.

[0134] The gap between the base 11 and the ceiling 12 obtained by the lifting initiation device 21 can thus correspond substantially to the height of the Y once the arms of the Y are straightened against each other. As detailed below, the gap continues to reach a spacing distance corresponding to the height of the straightened X and then continues to reach a spacing distance corresponding to the height of the straightened wall 8.

[0135] According to one embodiment, and as illustrated for example in [Fig. 8], the skid P21 carries a pulley (not shown) connected to a cable 290 and mounted to slide along the spar 121. The upper end 21 IA of the Y arm, located on the side opposite the X-shaped device, is articulated to said skid P21. The upper end 212A of the Y arm located on the side of the X-shaped device is articulated to the skid P2122, which also preferably carries a pulley (not shown) connected to the cable 290. The lower end 21 IB of the Y is formed by the end of the Y foot.

[0136] X-shaped lifting priming device

[0137] According to one embodiment and as illustrated more particularly in [Fig.8] and [Fig.9B], the lifting initiation device 22 comprises two arms 221, 222 crossed in a general X shape. The two arms 221, 222 are articulated with each other, and each has an upper end 221A, 222A connected to the spar 121 of the ceiling frame 120 by means respectively of a slider P2122 mounted sliding along said spar 121 and a piece L22 fixed relative to the spar.

[0138] In particular, the lower ends 221B, 222B of the X are free or possibly guided by a rail fixed to the ground or to the base, which extends parallel to the stringers 121, when they are supported on the ground or the base.

[0139] The lower ends 221B, 222B of the X remain free to move up and down relative to the base. Thus, once the lifting start has been achieved and the continued separation of the ceiling 12 from the base 11 is carried out by the continued movement of the pads P128 of the front and / or rear wall(s) along cross members of the ceiling, the lower ends 221B, 222B of the X move away from the floor or the base, the ceiling 12 carrying the base-separation starting devices 21, 22 with it in its upward movement.

[0140] Preferably and as illustrated in the Figures, the lower ends 221B, 222B of the X and the lower end 21 IB of the Y are fitted with casters to facilitate the deployment of the Y and the X when supported on the ground or on the base.

[0141] The upper end 221A of the arm 221 of the X is thus mounted to slide along the corresponding longitudinal member (frame element) of the ceiling frame 120. The same applies to the upper end 21 IA of the arm 211 of the Y and the upper end 212A of the arm 212 of the Y.

[0142] The SC28 control system allows the P2122 slider (also pushed by the P21 slider of the initiator device 21) to bring the ends 221A, 222A of the X closer together and thus tighten the arms of the X so that the lower ends 22IB, 222B bear against the base 11, for example an element of the base frame 110 (in the case where it is not intended that the entire structure in the folded state of the ceiling frame and the base frame can be moved on the ground), or against a floor element preferably located outside the base 11, preferably a floor on which the base IL rests

[0143] The continued tightening of the X arms causes the arms 221, 222 to straighten and thus the spreading or continued spreading (potentially initiated by the initiation device 21 or in parallel with the deployment of the initiation device 21) of the ceiling frame 120 relative to the base IL. In parallel with the support on a floor or on the base 11, of the lifting initiation device 22 which causes the ceiling frame 120 to spread apart relative to the base 11, the X device or each X device of the stabilization system 3 deploys (straightens) due to the spreading between the ceiling 12 and the base 11,Similarly, the wall panel 8 continues to straighten by pivoting upwards thanks to their articulation 118 at the base 11 and their sliding articulation mobility relative to the ceiling via the glides P128 and the articulation axes 128 which allow the corresponding front or rear wall panel to slide along cross members of the ceiling frame 120 towards the corresponding longitudinal member 121 of the corresponding ceiling frame 120.

[0144] Each arm 221, 222 of the X has a length greater than the height of the upright Y. Each arm 221, 222 of the X is longer than the length of the longest arm 211 of the Y, i.e., the length between the ends 21IA and 21IB.

[0145] In the upright state of the X and the Y, the point of articulation of the arms of the X with each other is higher than the point of articulation of the arms of the Y with each other.

[0146] The Y (or V) initiating device allows the separation between the ceiling 12 and the base 11 to be initiated with reduced effort, and helps to continue the deployment initiation by pushing on the X with the Y to continue straightening the X with reduced effort. The initiation system implemented using a Y and X device itself facilitates the continued deployment of the structure thanks to the inclination of the front and / or rear wall resulting from the separation achieved by the initiating system. The effort required to continue straightening the walls wall-mounted, by moving the P128 pads using the SC28 control system is indeed reduced due to the angle of inclination of the wall wall already reached 8.8'.

[0147] The gap between the base 11 and the ceiling 12 obtained by the motorized lifting initiation system S2 can thus correspond substantially to the height of the X once the arms of the X are straightened against each other.

[0148] Priming system pads

[0149] When the SC28 control system is activated, the pad 21 connected to the end 21 IA of the Y-branch 211 of the device 21 that is furthest from the X-branch 22 is moved towards the pad P2122 connected to the end 212A of the other Y-branch 212 so that the Y rights itself and the foot 21 IB of the Y rests on the base or the ground. Preferably, one end 221A of the X of the device 22 is also connected to said pad P2122. Alternatively, said end of the X may be connected to a pad, separate from pad P2122, against which pad P2122 is able to bear during its movement in the direction of the lifting initiation.

[0150] The movement of the pads P21, P2122 causes the Y to right itself. The Y resting on the floor or base at the same time as it rightes itself causes the ceiling frame 120 to move vertically away from the base 11. The pad P2122 of the X located near the Y is moved towards the other end 222A of the X, which is articulated to a fixed element L22 of the ceiling frame. The end 222A of the X of the device 22 is fixed along the longitudinal member 121. The term "fixed" is used to mean that it does not move along the longitudinal member, but of course the "fixed" end of the X remains articulated to the longitudinal member to allow the arms of the X to pivot during the movement of the pads P2122 and P21, which allows the X-shaped device to right itself, resting on the base or the floor.

[0151] Thus the X of the device 22 straightens and by support on the ground or the base causes the vertical separation of the ceiling 12 with respect to the base 11, up to a height of separation corresponding to the height of the straightened X.

[0152] Combining the Y (or V) device 21 with the X device 22 reduces the energy required to initiate the deployment of the structure. This is because the Y (or V) device requires less horizontal force to right itself during the initial deployment phase than the X device, due to the greater angle of attack of the Y (or V) relative to the X.

[0153] According to one embodiment and as illustrated in the examples, the structure comprises for each spar of the ceiling frame at least two X and Y (or X and V) initiating devices arranged at a distance from each other along the spar.

[0154] The deployment initiation system S2 (also called the lifting initiation system) allows the ceiling frame 120 to be moved away from the base frame 11 by a given distance. Conversely, the lifting initiation system S2 also allows the ceiling frame 120 to be moved closer to the base frame 11. The initiation system S2 also allows, when the ceiling frame is locked relative to the base, the entire base and ceiling assembly to be lifted to move the structure on the ground.

[0155] In one embodiment, the structure may include, for each guide rail of the roller, a drive wheel mounted outside the rail, or in another embodiment, a drive wheel may be integrated at one end of the V-shaped device 21 and / or the X-shaped device 22.

[0156] It is possible to foresee that in the embodiment in which a motor is integrated into a wheel of the device 21, and / or of the device 22, the structure may or may not include guide rails for these wheels.

[0157] Initiation of the straightening of the front and / or rear wall

[0158] As illustrated in the figures, the separation of the ceiling frame 120 from the base 11, generated by the actuation of the Y-shaped device 21 and the X-shaped device 22, initiates the straightening of the wall panel 8, 8'. In other words, the wall panel 8, 8' begins to straighten by pivoting around the joints 118, 128 at the same time as the Y and X are straightened at the initiation system S2 by bearing against the ground or the base. In particular, the separation of the ceiling 12 from the base 11 resulting from the actuation of the lifting initiation system 2 is thus accompanied by the beginning of the straightening of the wall panel 8, 8'.

[0159] Once the X and Y (or V) axes of the lifting initiation system S2 are fully straightened, further actuation of the control system SC28 allows the sliding movement of the corresponding wall pads P128 to continue, thus continuing the straightening of the wall pads 8 and consequently the separation of the ceiling 12 from the base 11 until the wall pad is fully straightened vertically. The ceiling then reaches its final separation distance from the base 11.

[0160] The fact that the lifting of the ceiling 12 can be initiated using the lifting initiation system 2 makes it possible to obtain an angle of inclination of the wall which is favorable to the straightening of the wall and therefore to the continuation of the lifting of the ceiling with reduced effort.

[0161] The entire wall panel, the associated glides, and the control system for moving these glides can thus be considered as forming a lifting finishing system S8 which makes it possible to finalize the separation of the ceiling 12 from the base 11, by straightening the front and rear wall panels 8, 8'. As a reminder, the separation of the ceiling 12 from the base 11 begins with the support of the priming system S2 on the floor or the base, and continues with the lifting completion system 4 by straightening the wall panels 8.

[0162] Stabilization system

[0163] As mentioned above, the structure includes a stabilization system that maintains parallelism and plumb between the ceiling frame and the base during the deployment (and retraction) of the structure. The stabilization system includes a stabilizing device 3 for each lateral side of the structure. The description given below for a stabilizing device 3 for one lateral side of the structure also applies to the stabilizing device provided for the opposite lateral side of the structure.

[0164] The upper ends of the stabilizing device 3 are connected to the ceiling 12, preferably to an end cross member 122 of the ceiling frame 120. According to one embodiment, the upper ends of the or each stabilizing device 3 comprise an upper end articulated to the ceiling 12 but which remains fixed along the cross member 122 of the ceiling frame 120, and an upper end movable along the cross member 122 of the ceiling frame 120.

[0165] According to one embodiment of the invention, the lower ends of the stabilization device 3 comprise a lower end articulated to the base 11, which remains fixed along the corresponding side of the base, and another lower end movable on the base (in particular along a part of the base forming a cross member of a base frame) or on the ground.

[0166] According to one embodiment of the invention and as in the example illustrated in the Figures, the stabilization system 3 comprises, for each lateral side of the structure, at least one X-shaped device comprising two arms 31,32 articulated to each other.

[0167] The arm 31 has one end fixed by being articulated 312 to the ceiling frame 120, and an opposite end 311 free, to allow it to move on the base 11 to accompany the straightening or folding of the X. It can be provided that the movement of the end 311 is guided by a rail on the base.

[0168] The other arm 32 has an end 321 articulated at the base 11, and an opposite end 322 mounted to slide freely in a rail along the corresponding cross member 122 of the ceiling frame 120.

[0169] It can be foreseen that the X-shaped device of the stabilization device 3 comprises a single X-shaped device, or two X-shaped devices arranged symmetrically with respect to the vertical median longitudinal plane of the structure.

[0170] Masking device

[0171] According to one embodiment, at least one, preferably each, spar 121 of the ceiling frame 120 is equipped with a masking device 129 which extends from the outside side of the spar 121 so that, in the folded (i.e. flattened or slumped) state of the lifting initiation system S2 along the corresponding spar 121, the initiation system S2 extends predominantly between the spar 121 and the masking device 129, i.e. behind the masking device 129 for a user located outside the structure, and therefore in a manner not visible to a user.

[0172] Thus, in the deployed position of the structure 1, and as in the example illustrated in the figures, the priming system S2 can be folded by extending along the corresponding stringer 121 of the ceiling frame 120 to be stored behind the corresponding masking device 129 and not be visible to a user.

[0173] The masking device 129 can be made on the periphery of the ceiling 12 so that, in the folded state of the structure, the stabilizing device 3 and the lifting initiation system S2 are masked (i.e., not visible to a user). When the structure is deployed, the masking device allows the lifting initiation system S2 to be masked, and when the structure is folded, the masking device can protect the mechanical components from moisture.

[0174] Mobility of the front and rear wall panels

[0175] As mentioned above, the wall panel 8 is mounted hinged to the base 11, preferably to a stringer 111 of the base frame 110 and sliding along cross members 123 of the ceiling frame 120, being hinged to the sliding pads P28 so as to be able to pivot relative to said cross members 123, at the same time as said wall panel 8 is moved sliding along the cross members 122.

[0176] For this purpose and as illustrated for example partially in [Fig.8], the structure 1 includes for the wall panel 8, a control system S8 configured to move by sliding the skates P128 which connect the wall panel 8 to the ceiling 12. Each skate P128 is mounted to slide on a cross member 123, preferably an intermediate cross member, of the ceiling frame.

[0177] For each skate P128, the control system S8 comprises, carried by said skate P128, a pulley 828 and a pivot pin 128 to which an upper end of the wall panel 8 is articulated. The term "upper" is used with reference to the vertically extended state of the wall panel 8. Another pulley 824 is located at the end of the cross member 123 along which the skate P128 is mounted to slide, on the side of the ceiling stringer 121 along which the wall panel 8 extends in the upright position. A cable 290 (or rope) extends from the pulley 828 carried by the skate P128 to the pulley 824, which is fixedly positioned relative to the cross member 123 and relative to the stringer 121. The pulley can rotate about itself but is not movable along any element of the ceiling frame. Pulley 824 allows cable 290 to be redirected coming from the winch T28 on which it is wound, to the pulley 828 carried by the skid P128. After passing through the pulley 828, the cable 290 is returned to a pulley (not shown) which is carried by the ceiling frame 120, preferably in the part L22, in particular by the stringer 121 (for example a connecting part L22 between the stringer 121 and the intermediate cross member 123 along which the skid P128 can slide).

[0178] The cable 290 is returned from said pulley to a movement system for the second skate P128 which includes, as for the first skate P128, a set of pulleys comprising a pulley 828A carried by the second skate P128, and a pulley (not shown) carried by a part L23 attached to the ceiling frame 120. The cable 290 thus passes through the pulleys to be attached to a part, preferably part L23, attached to the ceiling frame 120.

[0179] Advantageously, the cable 290 also passes through one or more pulleys (not shown) carried by pads P2122, P21, to which are articulated a part of the X-starting device 22 and the Y-starting (or V-starting) device 21.

[0180] The winch T28, preferably motorized by an M28 motor, to which the cable 290 is attached, then allows the winding and unwinding of the cable 290 and thus the movement of the pads P21, P2122 of the initiating devices 21, 22, as well as the pads P128 of the wall wall 8 along the cross members of the ceiling frame.

[0181] The SC28 control system described and illustrated for example in [Fig.8] for the wall panel 8 and the devices in Y 21, and in V 22, also applies to a control system for the wall panel 8', preferably arranged symmetrically to said SC28 control system, and the corresponding priming devices in X and Y (or V).

[0182] Advantageously and as illustrated for example in [Fig.8], the structure includes, for each front and / or rear side of the structure 1, a return spring system R8 which is compressed by the corresponding wall wall 8 in the upright position, so that the spring R8 allows during the folding phase of the structure, to initiate the movement of the wall wall 8 in the direction of a folding, i.e. to initiate the movement of the pads P128 of the wall wall to the spacing of the longitudinal member 121 along which the wall wall 8 extends in the upright state.

[0183] According to one embodiment, a sensor system makes it possible to detect different positions of the Y (or V) and the X of the priming devices 21, 22, as well as the position of the wall panels, to facilitate an automation of deployment / retraction and / or movement on the ground.

[0184] Side wall panel

[0185] The structure further includes at least on one lateral side, preferably on each lateral side, a lateral wall 5.5', called a gable, configured to be able to move from a position stored substantially parallel to the ceiling frame 120 to an upright position (parallel to the stabilization devices 3) which at least partially closes the corresponding lateral side (or corresponding lateral face) of the structure.

[0186] The description given below for the side wall (gable) 5 also applies to the opposite side wall 5'.

[0187] For this purpose, the structure includes a control system 500 to control the passage of the side wall 5 from the open position to the closed position and vice versa.

[0188] An example of a 500 control system is described in connection with Figures 10A and 10B.

[0189] According to one embodiment of the invention and as illustrated for example in [Fig. 1OA], the movement control mechanism 500 comprises, for at least one, preferably for each lateral side of the side wall, a motor 510, a winch 515, a pulley 528 and a cable 529 passing through the pulley 528 and attached to a lower end of the side wall 5. It may be provided that a part of the control system, for example the motor 510 and the winch 515, is common for both sides of the side wall 5.

[0190] The side wall 5 can extend and slide along a guide rail 125 parallel to the stringer 121 of the ceiling frame. One end of the cable 529 is connected to the winding / unwinding winch 515, which is operated by the motor 510, and the other end of the cable 529 is connected to a lower end 502 of the side wall 5 (the end 502 is considered the "lower end" in the vertically extended state of the side wall 5). Said lower end 502 is preferably equipped with a rolling element, such as a roller, as is the opposite upper end 501 of the side wall.

[0191] The guide rail 125 guides the movement of the wall panel and, when the lower end 502 reaches the end of its travel at an opening 1255 in the guide rail 125 (see [Fig. 1OA]), allows the wall panel to tilt for vertical alignment ([Fig. 1OB]). Indeed, at the end of the horizontal guide rail's travel, the lower end 502 moves away from the guide rail and is guided in a corresponding vertical rail (not shown) of the corresponding wall panel 8, 8'.

[0192] The side wall panel 5 is brought into the deployed (upright) position by a thrust spring 590 (for example, made using a jack) one end of which is connected to a part 129 which bears against a portion of the wall panel, preferably a roller located at the lower end 502. The motor 510 prevents the sudden deployment of the side wall panel 5 by controlling the unwinding of the cable 529 of the winch 515. The thrust spring 590 acts as an imbalance and thrust spring configured to maintain the seal of the side wall panel 5. in vertical configuration against end stops located at the level of the uprights formed by the lateral sides of the wall panels 8, 8' front and rear.

[0193] The motorization 510 also allows the side wall panel 5 to be raised by winding the cable 529 of the winch 515.

[0194] Thus, for the passage from the stowed position to the deployed position of the side wall 5, the lower end 502 of the side wall 5 slides or rolls on the horizontal rail 125, then falls into the vertical rail (not shown) of the corresponding wall wall 8, 8', while the upper end 501 continues to slide or roll on the horizontal rail 125 until it comes to the end of its travel in or opposite the vertical rail of the corresponding wall wall 8, 8'.

[0195] Deployment method

[0196] An example of a deployment method is shown below.

[0197] Initially, the structure is in the folded position (example in [Fig. 1] and [Fig. 9A]). Advantageously, the initiation system S2 is masked by the masking device 129. According to a particular aspect, the initiation system S2 extends between a ceiling stringer and said masking device 129. Said masking device 129 may be in the form of an elongated L-shaped element that extends cantilevered from the stringer and optionally also along a cross member of the ceiling frame to form a peripheral masking contour that also at least partially masks the stabilizing device 3 in the folded state.

[0198] As illustrated in [Fig.2] and [Fig.9B], the S2 priming system is controlled in the direction of deployment.

[0199] As mentioned above, the upper end 222A of the X arm of the priming device 22, located on the side of the X opposite the priming device 21 in Y, is articulated to the spar 121, preferably via the part L22 as illustrated in [Fig.8], without any sliding freedom relative to the spar 121. In other words, said upper end 222A of the X arm of the priming device 22 is fixed against translation while being articulated to allow the deployment / folding of the X of the priming device 22.

[0200] Actuation of the SC28 control system, which winds the cable 290 around the winch T28, causes the movement of the pads P21, P2122 (example in [Fig. 8]), to which the Y-shaped device 21 and the X-shaped initiator 22 are connected. The pads P21, P2122 are thus moved towards the fixed end 222A of the X, i.e., in the direction of a straightening of the Y and the X. In particular, the pad P21, to which the end 21 IA of the arm 211 of the Y is connected, moves closer to the pad P2122, to which the end 212A of the other arm 212 of the Y and the end 221A of the arm 221 of the X are connected. The two pads P21, P2122 together move closer to the fixed end 222A of the arm 222 of the device 22 priming in X, which leads to the rectification of Y and X. When the Y and the X touch the base or the ground, the continuation of their straightening results in a separation of the ceiling frame 120 from the base 11 (in the case where the separation mobility has not been blocked of course).

[0201] Once the priming system S2 is fully erected, the continued operation of the control system SC28 causes the sliding movement of the pads P128 of the wall wall 8 to continue along the corresponding cross members of the ceiling frame 120, while the wall wall 8, hinged at the base, pivots relative to the base and the ceiling, so that the wall wall 8 straightens and extends parallel to the stringers of the ceiling frame and orthogonally to the ceiling frame.

[0202] It can be noted that during the initiation phase, when the SC28 control system causes the Y and X devices of the initiation system S2 to straighten in order to begin the separation of the ceiling 12 from the base 11, the P128 pads slide to accompany the separation movement so that the wall 8 begins to straighten. When the initiation devices 21, 22 are fully straightened and can no longer contribute to further separation of the ceiling 12 from the base 11, it is the movement of the P128 pads, controlled by the winch T28, that allows the ceiling 12 to continue moving from the base 11, by straightening the wall 8.

[0203] Preferably, each front and rear side of the structure 1 is equipped with a priming system S2, a lifting tracking system S8, and a corresponding control system, such as the SC28 system. It may be provided that a portion of the SC28 control system is common to both the front and rear sides of the structure 1.

[0204] Preferably, said pulleys of the SC28 control system, in particular 828, 824 are connected together by the same cable or rope 290. The winch 28 then allows the cable connecting said pulleys to be wound / unwound and thus to be able to move the corresponding pads of the wall 8 and the lifting starting devices 21, 22.

[0205] The description given above for the straightening of the wall panel 8 can also be applied to the straightening of the wall panel 8'.

[0206] The Y-shaped initiation device 21 helps to deploy the X of the initiation device 22 by pushing longitudinally (i.e. in a direction parallel to the spar 121) on the X of the initiation device 22.

[0207] The angle of attack of the Y (or V) of the priming device 21 is defined as the angle of an arm of the Y (or V) with respect to the horizontal (which corresponds to the direction of the spar of the ceiling frame) when the foot of the Y (or the tip of the V) touches the ground or the base.

[0208] Similarly, the angle of attack of the X of the priming device 22 is defined as the angle of an arm of the X with respect to the horizontal when the lower ends of the X touch the ground or the base. The X of the initiation device 22 and the Y (or V) of the initiation device 21 are configured such that the angle of attack of the Y of the initiation device 21 is greater than the angle of attack of the X of the initiation device 22. This allows the Y of the initiation device 22 to be straightened, and then, as the Y straightens, the Y of the initiation device 21 pushes on the X of the initiation device 22, thus contributing to the straightening of the X of the initiation device 22. This configuration of the initiation devices 21 and 22 limits the forces required for the initial phase of separating the ceiling 12 from the base 11.As mentioned above, once the X and Y (or V) of the initiation devices have reached the ground support, the continuation of their straightening causes the ceiling 12 to move away from the base 11, which is accompanied by a beginning of straightening of the front and rear wall walls 8, 8', and which allows a more favorable angle of attack of the wall walls to continue their straightening until the end of the deployment of the wall walls 8, 8'.

[0209] The deployment (straightening) of the X is facilitated by the effect of the thrust of the V-shaped lifting initiation device 21 on the X-shaped lifting initiation device 22 along the spar.

[0210] In parallel, the X-shaped device or devices of the stabilization system 3 continue to deploy, accompanying the separation of the ceiling 12 from the base 11.

[0211] Continued actuation of the SC28 control system causes the P128 pads of the wall panel 8 to move towards the corresponding stringer 121, so that the wall panel 8 straightens by pivoting around its joints at the base, until it reaches a vertically upright position to at least partially close the front face of the structure (an example is shown in [Fig. 5]). The wall panel 8 then preferably extends between the ceiling stringer and a portion of the base located directly above the stringer. In a preferred embodiment, the wall panel 8 abuts against a reinforcing and sealing fold.

[0212] After the lifting initiation system S2 has finished initiating the lifting of the ceiling 12 and the lifting continuation system S8 has taken over the lifting of the ceiling frame 120, the continuation of the lifting of the ceiling frame 120 relative to the base 11 by straightening the front and / or rear wall(s) of the lifting continuation system S8 causes the separation (lifting) of the V-shaped device 21 and the X-shaped device 22 relative to the base 11, because the initiation system S2 is supported by the ceiling 12.

[0213] Rails can be fixed to the floor or to the base for guiding the casters of the Y-shaped device 21, and of the X-shaped device 22 when they are resting on the floor or on the base, without preventing the lifting of device 21 in Y, and of device 22 in X during the continuation of straightening of the front and / or rear wall(s).

[0214] In particular, as the wall panel 8 slides along ceiling crossbeams via the glides P128, the wall panel pivots relative to said crossbeams by means of its joints 118, 128 at the base and at the glides P128 supported by the ceiling. This sliding and articulated mounting of the wall panel allows the ceiling to be actively moved further apart from the base, a movement initiated by the deployment of the initiation system S2.

[0215] Thus, when the X and Y of the initiation system S2 have finished straightening, the continued straightening of the wall 8 allows the ceiling 12 to continue rising relative to the base 11, the stabilizing device 3 accompanying this separation by continuing to deploy (straighten). The devices 21 and 22, which are linked to the ceiling 12, are then no longer supported by the ground or the base and are moved upwards with the ceiling 12.

[0216] The Y and X devices 21 and 22 are preferably returned by a spring system to a folded position parallel to the spar, so that the Y and X devices 21 and 22 can return to the initial position along the spar 121, even in the deployed state of the structure 1 (example in [Fig.6]), preferably being masked by the masking device.

[0217] As seen in the example of [Fig.6], it can be foreseen that the side wall 5 is brought into the deployed (upright) position by a push spring 590, in combination with the motor 510 which controls the unwinding of the cable 529 attached to the side wall 5 to control the movement and prevent a sudden tilting of the side wall 5. The description given below for the side wall (pinion) 5 also applies to the opposite side wall 5'.

[0218] The movement of the side wall 5 into the upright position is preferably triggered when the wall wall 8 reaches the end of its vertical deployment stroke, i.e. in the upright position.

[0219] Advantageously, the jack 590 allows the side wall 5 to be held against the uprights of the wall wall 8, in the vertical configuration of the side wall 5.

[0220] The motorization 510 allows the side wall 5 to be raised in relation to the ceiling 12, if it is desired to open the corresponding side of the structure, or when folding the structure.

[0221] The deployment of the structure thus comprises two main phases:

[0222] - the first phase includes initiating the lifting of the ceiling 12 by the device The Y-shaped priming device 21 and the X-shaped priming device 22 are used as lever arms, which allows the ceiling 12 to be detached from the base 11 so that the angle for the lifting of the wall(s) 8.8' front and / or rear is more favorable;

[0223] - for the second phase, given that the angle allowing the deployment of the or The 8, 8' front and / or rear wall panels are now more favorable, the continued movement of the P128 pads of the 8,8' wall panels along the crossbeams of the ceiling frame is facilitated, which allows the ceiling 12 spacing to be finalized with reduced effort and thus the deployment of structure 1.

[0224] The M28 motor can be released (freewheeling) and / or operated in the opposite direction, to allow a return spring to bring the X and Y initiator pads back to the initial position, for example to bring them into a retracted position behind the masking device 129.

[0225] Folding method

[0226] Folding can be carried out by repeating the steps described above in reverse order.

[0227] Steering unit

[0228] The structure may include a control unit for driving the motors of the control systems, in particular the M28 motor of the SC28 control system and the 510 motor.

[0229] The control unit is presented for example in the form of a processor and a data memory in which computer instructions executable by said processor are stored, or in the form of a microcontroller.

[0230] In other words, the functions and steps described can be implemented as a computer program or via hardware components (e.g., programmable gate arrays). In particular, the functions and steps performed by the control unit, especially for motor control, can be implemented by instruction sets or computer modules implemented in a processor or controller, or by dedicated electronic components or components such as field-programmable gate arrays (FPGAs) or application-specific integrated circuits (ASICs). It is also possible to combine computer and electronic components.

[0231] The control unit is thus an electronic and / or computer unit. When it is specified that said unit is configured to perform a given operation, this means that the unit includes computer instructions and the corresponding means of execution which enable said operation to be carried out and / or that the unit includes corresponding electronic components.

[0232] According to one embodiment of the invention, the walls and the stringers and / or crossbeams of the structure, and optionally the base, may include an extension mechanism depending on the desired dimensions.

[0233] It can be foreseen that the structure will be fitted with louvers or bays.

Accordingly, it should be understood that, where the features mentioned in the appended claims are followed by reference numerals, these numerals are included solely for the purpose of improving the intelligibility of the claims and are in no way limiting the scope of the claims.
