Description

TECHNICAL FIELD OF THE INVENTION

The field is that of the devices of protection of the bad weather and/or the sun.

STATE OF THE ART

Classically, a device for protection against the bad weather and/or the sunlight, such as an umbrella, a parasol or a sunshade, comprises a frame comprising a mast which may or may not be telescopic, on which a runner is mounted so that it can slide between a first position in which the device is closed and a position in which the device is open. The frame comprises ribs connected to a notch or support attached to one end of the mast and to the runner by means of stretchers or sub-ribs.

In one embodiment, it has been proposed to attach the ends of the ribs to a circumferential wire integral with the notch. The ends of the stretchers opposite to those connected to the ribs are connected to the runner by another circumferential wire integral with the runner. The deployment of the frame is achieved by sliding the runner which induces a deployment of the ribs. The angular spacing of the ribs is obtained by the tensioning of the protective fabric fixed to the ribs and by the connection by wire of the ribs and the stretchers which authorize an angulation of the ribs the ones relatively to the others. If this type of system can be very compact in closed position, it proves in practice to be very fragile to use because of the not very rigid connections, on the one hand, of the stretchers to the runner and, on the other hand, of the ribs to the notch.

Note that a weather protection device has the primary function of protecting from rain but can also be used to protect from the sun. Also a sun protection device that has the primary function of protecting from the sun can also be used to protect occasionally from the rain.

Also, a protective device as described above and used in its function of protection from the weather, necessarily turns out to be wet when it is closed again immediately after use in the rain for example. Thus, when the user arrives at a given location (restaurant, work, . . . ) it is known to place the device in a receiving container, for example cylindrical, allowing water to flow downwards to allow drying of the device fabric. Another method consists in deploying the device in a dry place (garage, covered terrace, . . . ) in order to carry out the drying of the fabric. It is understood that either method requires the device to be stored for a fairly long period of time and does not make it possible for the user to carry the device in a closed state due to the presence of water drops on the fabric, in a bag for example, the surrounding belongings then being wet.

The invention aims to remedy all or part of the above-mentioned problems and drawbacks in a simple and reliable manner.

PRESENTATION OF THE INVENTION

Thus, the present document relates to a deployable frame, in particular for a weather and/or sun protection device, comprising:

• • a mast with a longitudinal axis on which is mounted a slider that slides between a first position in which the frame is closed and a second position in which the frame is open;
  • at least one rib connected by a stretcher to the runner, the rib comprising an end connected to a notch carried by one end of the mast, characterized in that:
  • the rib comprises a first segment formed by a first part and a second part that are movable with respect to each other about the extension axis of said first segment,
  • the first part of the first segment of the rib is connected to the notch by a pivot connection about an axis which is perpendicular to a plane inclined obliquely to the longitudinal axis of the mast so that in the first closed position of the frame the first segment of the rib extends along the mast and in the second open position of the frame the first segment of the rib is moved away from the mast.

According to the proposed configuration, when the frame is deployed, the first segment articulated by a pivot connection to the notch can thus move away from the mast by pivoting around an oblique axis, while the second part of said segment can move away from the mast while performing a rotational movement around the extension axis of the first segment. Thus, the attachment of a protective cloth can be fixed to the second part of the first segment and the cloth does not undergo a rotational movement around the axis of the segment. Moreover, the mechanical connection of the first segment to the notch allows to guarantee an increased rigidity of the connection of the rib to the notch compared to the previous technique while ensuring a distance of the rib from the mast when the frame is in its second opening position. According to another characteristic, a first end of the stretcher can be connected to the runner by a ball-and-socket connection. It could also be connected to the mast via a circumferential wire integral with the runner.

The ball-and-socket connection may comprise a spherical part carried by the first end of the stretcher and housed in a cavity of complementary shape of the runner. The reverse would also be possible, i.e. a cavity carried by the first end of the stretcher and a spherical part carried by the runner.

A second end of the stretcher can be pivotally connected to the second part of the first segment of the rib. In combination with the ball-and-socket connection of the first end of the stretcher, this configuration provides further increased rigidity of the rib/stretcher assembly due to the absence of circumferential play, i.e. around the axis of the mast, of the first end of the rib with the runner.

Also, elastic means can be configured to exert a force tending to deploy the frame when it is in its first position. In particular, they may comprise an elastic member interposed between the first segment and the mast when the frame is in its first closed position.

The elastic member may comprise a tongue carried by the stretcher and elastically constrained between the stretcher and the mast when the frame is in its first position. In this way, the tongue exerts a force tending to deploy the frame, allowing to facilitate the initial deployment movement of the frame by performing an automatic pre-deployment thereof.

In one embodiment of a rib for a deployable frame as described herein but which may also be used in other deployable frames not having the aforementioned specifics, each rib may comprise n segments S arranged at the end of each other from the first segment S₁ to an n-th end segment S_n, and wherein:

• • for any k∈[2,n−1]
    • the k-th segment S_k is connected to the segment S_k−1 by a pivot axis P_Sk−1/Sk and is connected to the segment S_k+1 by a pivot axis P_Sk/Sk+1,
    • a rod T_k is associated with the segment S_k and is connected by a pivot axis P_Tk/Sk−1 and by a pivot axis P_Tk/Sk+1 respectively, to the segment S_k−1 and to the segment S_k+1
  • in such a way that each segment S_k together with a rod T_k forms a deformable parallelogram.Each k-th rod T_k may comprise a bulge R_Tk for receiving the pivot axis P_Tk+1/Sk and the pivot axis P_Sk/Sk+1 when the frame is in its first position. Each k-th segment S_k comprises a bulge R_Sk for receiving the pivot x is P_Tk/Sk-when the frame is in its first position. These bulges make it possible to obtain an increased compactness of the rib when the frame is in its first position, i.e. when the segments of the rib are folded on each other.

The pivot axes P_Tk/Sk−1, P_Sk/Sk−1 and P_Tk−1/Skk can be positioned relative to each other such that said pivot axes are substantially aligned when the frame is in its first position, the pivot axis P_Sk/Sk−1 being positioned between the pivot axis P_Tk/Sk−1 and the pivot axis P_Tk−1/Sk.

The frame may comprise a first rod T₁ pivotally connected to the stretcher and pivotally connected to the second segment S₂ by a pivot axis P_T1/S2.

Said first rod T₁ may comprise a bulge R₁ for receiving the pivot axis P_S1/S2 and the pivot axis P_T2/S1.

Thus, the present document also relates to a rib as such, which rib may comprise a first one-piece segment, i.e., not comprising a first part and a second part rotatable relative to each other.

In a more particular configuration, the frame may comprise a first rib and a second rib as describes of the type recited in any of the preceding claims, the first rib being symmetrical to the second rib about a plane containing the longitudinal axis of the mast and passing between the first rib and the second rib.

The axis of the pivot connection of the first rib and the axis of the pivot connection of the second rib can be contained in the same plane parallel to the longitudinal axis of the mast.

Similarly, the frame may comprise a third rib and a fourth rib of the type recited any of the preceding claims, the third rib being symmetrical to the fourth rib about a plane containing the longitudinal axis of the mast and passing between the third rib and the fourth rib.

The axis of the pivot connection of the third rib and the axis of the pivot connection of the fourth rib can be contained in the same plane parallel to the longitudinal axis of the mast.

The first rib may be symmetrical to the third rib with respect to a plane containing the longitudinal axis of the mast and passing between the first rib and the third rib.

The second rib may be symmetrical to the fourth rib with respect to a plane containing the longitudinal axis of the mast and passing between the second rib and the fourth rib.

The mast may have a generally oblong cross-section with two opposing surfaces connected to each other by two rounded surfaces.

More particularly, the mast may have two flat surfaces substantially parallel to each other and to the longitudinal axis, said two flat surfaces being connected to each other by joining portions which may be straight circular half-cylinders with generatrices parallel to the axis of the mast. Obviously, this shape is a particular shape falling within the definition of a general oblong shape within the meaning of the present disclosure. Thus, one and/or other of the planar surfaces could be replaced by a non-planar surface and the half-cylinders could have non-spherical rounded shapes. For example, one of the four aforementioned surfaces could have a groove from one end of the mast to the other to facilitate sliding cooperation of unitary elements forming a telescopic mast.

The axis of the pivot connection of the first rib and the axis of the pivot connection of the second rib can be arranged in the vicinity of one of the two rounded surfaces. In this configuration, the first rib and the second rib are thus arranged side by side when the frame is in its first closed position. It would also be possible to have the axis of the pivot connection of the third rib and the axis of the pivot connection of the fourth rib arranged in the vicinity of the other of the two rounded surfaces. In this manner, the third rib and the fourth rib are arranged side by side when the frame is in its first closed position. It is understood that the frame thus offers, seen from above, i.e. along the axis of the mast and from the notch, a substantially rectangular general shape when it is in its second position, each rib being arranged in the corners of said rectangular shape.

The present document also relates to a weather conditions and/or sun protection device comprising at least one frame according to one of the preceding claims, and a protective cloth attached to said frame so as to be tensioned when said frame is brought into its second position.

A handle element can be mounted at an end of the mast opposite to the one receiving the notch.

The device may include a case adapted to be mounted around the frame when the frame is in its first closed position, the case sealingly engaging the handle member to form a sealed casing.

As will be understood, the present disclosure of the frame is usable, in particular, in a weather protection device such as rain or in a sun protection device such as a sunshade, which are transportable or portable devices. It is also applicable to non-transportable devices that would use the same operating principle.

The present disclosure therefore also applies to protective devices comprising a single rib or only two or three ribs.

Independently or in combination with any of the previously described features, the present disclosure also relates to a weather and/or sun protection device, comprising:

• • a frame deployable between a first position in which the frame is closed and a second position in which the frame is open, said frame supporting a protective fabric;
  • a mast with a longitudinal axis (L) on which a runner is intended to be mounted, capable of deploying the frame by sliding along the mast;
  • a handle element carried by one end of the mast;
  • characterized in that it comprises a case in which all or part of the deployable frame is able to be housed when the latter is in its first closed position and in that the case and the handle element are configured to cooperate in a sealed manner with each other when the frame is in its first position so as to form a sealed casing.

This specific assembly makes it possible to achieve a watertightness of the casing formed by the case and the handle element. In this way, the user can easily transport the device and place it in a bag or any other container suitable for receiving it without the objects or belongings in said container or the walls of said container getting wet.

The device can be shaped to fit in a trouser pocket or in an inner pocket of a suit jacket and it is easy to understand the interest for a user to keep his protection device with him without having to worry about where he has placed it and having to think about retrieving it, the device accompanying him in the same way as his other things.

As mentioned, the use of a waterproof casing can be achieved with the deployable frame described above, so that the protective device can then be extremely compact.

According to another feature of the present document, at least one sealing piece may be interposed between the case and the handle element. The at least one sealing member may be an annular seal that may be closed or open contour, i.e., slotted, depending on the conformation of the case.

Also, one of the case and the handle element includes at least one movable member that is movable between a first position for sealingly locking the handle element to the case and a second unlocking position for disengaging the handle element from the case.

Alternatively, the case may include a fixed portion and said movable member that is articulated for movement relative to the fixed portion between the first position and the second position. In this configuration, the movable member forms at least a portion of the removable case relative to the handle element. In another configuration, the movable member comprises a fixed portion and a movable portion.

The term “fixed” here refers to a portion of the case or handle member that does not move relative to the handle member or case, respectively, when said fixed portion is brought into a position capable of being locked or unlocked. In this position, the movable part is movable between its two locking and unlocking positions.

The device may include guiding means configured to allow movement of the movable member between the first locking position and the second unlocking position.

The guiding means may comprise at least one rod carried by the fixed part of the case and at least one housing in which said rod is engaged to guide the movement of the rod in the housing. The movable member may comprise two opposing webs each having a housing, said at least one rod being engaged in said housings of said two webs.

Said at least one groove may be shaped to allow translation of the movable member from the first position to an intermediate position and then to allow pivoting of the webs of the movable member to a position corresponding to the second position of the movable member.

Said movable member may comprise a first upper hook adapted to cooperate by elastic snap-fastening with a first hook of complementary shape of the fixed part of the case when the movable member is in its first position so as to block said movable member on the fixed part of the case along the longitudinal direction.

Said movable member may comprise a second lower hook adapted to cooperate by elastic snap-fastening with a second hook of complementary shape of the handle element when the movable member is in its first position so as to block a movement of the movable member in a direction perpendicular to the longitudinal direction.

The case may comprise a first movable member and a second movable member of the aforementioned type, the first movable member and the second movable member being arranged relative to each other so that they move away from each other from their first position to their second position.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 includes a first portion named FIG. 1A and a second portion named FIG. 1B. FIG. 1A depicts a bad weather and/or sunlight protection device 10 comprising a deployable frame 12 having a protective fabric 14 attached thereto and a handle member 16 that is attached to one end of a mast 18 of the frame 12. FIG. 1B illustrates an assembly 20 comprising a device 10 and a case 22 in which the frame and the fabric 14 are intended to be accommodated. The handle member 16 includes a free edge 24 applied to and sealingly engaging a free edge 26 (FIG. 1B) of the case 22 by means of an annular seal 28 (FIG. 3). The handle member 16 includes side tabs 30 for hooking onto complementary portions of the case 22 in order to secure the case 22 to the handle member 16 (FIGS. 1B and 2). Thus, when the frame 12 and the fabric 14 are accommodated in the case 22 and the case 22 performs a sealing function with the handle element 16, the assembly 20 (FIG. 1B) thus formed can be placed in a bag, an inner pocket of a jacket or a pocket of a pair of pants, without the residual drops present on the fabric 14 coming out and wetting the objects in contact with the assembly 20.

It is observed that the case 22 as well as the handle member 16 have a rectangular parallelepiped shape having a length or height 11, a width 12 and a thickness 13. The length 11 is greater than the width, which is itself greater than the thickness 13. It will later be understood that the proposed shape of the case formed by the case 22 and the handle element 16 is enabled by the use of specific deployment/closure kinematics of the ribs B₁, B₂, B₃, B₄ (FIG. 2) and by a relative arrangement of the ribs B₁, B₂, B₃, B₄ with respect to each other, allowing for an increased compactness of the device 10 in the closed position compared to devices of the prior art.

FIG. 2 depicts the frame 12 together with the handle element 16, the case 22 and the canvas 14 not being shown in order to visualize the frame 12 of the device 10 in its first closed position. The frame 12, according to the present disclosure, thus comprises a mast 18 which is telescopic here but which could also be non-telescopic so that the present disclosure also covers non-telescopic masts. The telescopic mast 18 thus comprises five tube portions 18₁, 18₂, 18₃, 18₄ 18₅ engaged with each other. The mast 18 has a transverse section, i.e., in a plane perpendicular to the longitudinal axis L of the mast 18, of generally oblong shape.

A runner 32 is mounted around the mast 18 and configured to slide along the longitudinal axis L of the mast 18 between the first closed position of the frame 12 (FIGS. 2 and 3) and a second open or deployed position of the frame 12 (FIGS. 9 to 11). As can be seen in FIGS. 2 to 10, the frame 12 comprises four ribs noted B₁, B₂, B₃, B₄. Each rib B₁, B₂, B₃, B₄ is associated and connected to a stretcher F which is connected to the runner. Furthermore, each rib B₁, B₂, B₃, B₄ is connected to a notch 34 or support integral with the end of the mast 18 which is opposite that carrying the handle element 16. Since the mast 18 is telescopic, the notch 34 is integral with one end of the tube portion 18₅ that is located radially further inward relative to the other tube portions (FIGS. 2, 5 and 8). It can be seen that the notch 34 comprises an upper base 36 connected to a tube portion 38 which is also oblong in shape and surrounds (but could be the reverse) and is attached to the end of the tube portion 18₅.

As can be seen, each rib B₁, B₂, B₃, B₄ comprises n segments S arranged one after the other from a first segment S₁ to an n-th segment S_n (FIGS. 9 and 12). The first segment S₁ of each rib B₁, B₂, B₃, B₄ is formed by a first part 40 and a second part 42 which are movable with respect to each other around the extension axis of said first segment S₁ (FIGS. 5, 6, 8 and 10). The structure of each rib B₁, B₂, B₃, B₄ will be described in more detail later, with reference to FIGS. 12 and 13.

As can be seen in FIGS. 5, 6, 8, 10 and 11, one end of the first portion 40 of the first segment S₁ of each rib B₁, B₂, B₃, B₄ is connected by a pivotal connection about a pivot connexion around an axis P_B1, P_B2, P_B3 and P_B4 which are each perpendicular to a plane inclined obliquely to the longitudinal axis L of the mast 18. The other end of the first part engages an end of the second part and the first part and second part are rotatable relative to each other about the extension axis of the segment S₁. The term “pivot axis” or “axis” in connection with a pivot connection refers both to the material element serving as a pivot which is centered on the immaterial axis and to the material axis or rod as such. The first part 40 of the first segment S₁, and also the segment S₁ as such of the rib B₁, are rotatably articulated on the notch about a pivot axis P_B1 perpendicular to a plane P₁ inclined obliquely with respect to the longitudinal axis L of the mast 18. The first part 40 of the first segment S₁, and also the segment S₁ of the rib B₂, are articulated in rotation on the notch about a pivot axis P_B2 perpendicular to a plane P₂ inclined obliquely with respect to the longitudinal axis L of the mast 18. The first part 40 of the first segment S₁, and also the segment S₁ as such of the rib B₃, are articulated in rotation on the notch about a pivot axis P_B3 perpendicular to a plane inclined obliquely with respect to the longitudinal axis L of the mast 18. The first portion 40 of the first segment S₁, and also the segment S₁ as such of the rib B₄, are rotatably articulated to the notch 34 about a pivot axis (not shown) perpendicular to a plane obliquely inclined with respect to the longitudinal axis L of the mast 18. More particularly, it is observed that the first rib B₁ (FIG. 4) is symmetrical to the second rib B₂ with respect to a plane A containing the longitudinal axis L of the mast 18 and passing between the first rib B₁ and the second rib B₂. Also, the axis P_B1 of the pivot connection of the first rib B_1-1 and the axis P_B2 of the pivot connection of the second rib B₂ are contained in the same plane B parallel to the longitudinal axis of the mast 18. The third rib B₃ is symmetrical to the fourth rib B₄ with respect to a plane C containing the longitudinal axis L of the mast 18 and passing between the third rib B₃ and the fourth rib B₄. Also, the axis P_B3 of the pivot connection of the third rib B₃ and the axis P_B4 of the pivot connection of the fourth rib B₄ are contained in the same plane D parallel to the longitudinal axis L of the mast. Thus, the plane B and the plane D are parallel to each other. Also, the first rib B₁ is symmetrical to the third rib B₃ with respect to a plane E containing the longitudinal axis L of the mast 18 and passing between the first rib B₁ and the third rib B₃. The second rib B₂ is symmetrical to the fourth rib B₄ with respect to a plane F containing the longitudinal axis L of the mast 18 and passing between the second rib B₂ and the fourth rib B₄. Due to the above symmetries, the plane A and the plane C are merged and so are the planes E and F.

FIG. 6 being a side view of the ribs B₁ and B₂ only, and in a direction perpendicular to the longitudinal direction L of the mast, it is understood that the oblique planes P₁ and P₂ are perpendicular to the plane of the page.

In an example, the axes P_BA and P_B2 form an angle of approximately 45° with plane A (FIG. 6). Similarly, the axes P_B3 and P_B4 form an angle of approximately 45° with plane C (FIGS. 4 to 6).

The mast 18 has a generally oblong cross-section comprising two opposing planar surfaces 44 part A of FIG. 4 facing to each other and connected to each other by two rounded surfaces 46. The axis of the pivotal connection of the first rib B₁ and the axis of the pivotal connection of the second rib B₂ are in the vicinity of one of the two rounded surfaces 46. In this configuration, the first rib B₁ and the second rib B₂ are thus arranged side by side when the frame 12 is in its first closed position. The axis of the pivot connection of the third rib and the axis of the pivot connection of the fourth rib B₄ are arranged in the vicinity of the other 46 of the two rounded surfaces. In this manner, the third B₃ rib and the fourth B₄ rib are arranged side by side when the frame 12 is in its first closed position. It is understood that the frame 12 offers, seen from above, i.e. along the axis L of the mast 12 and from the notch 34 (FIG. 4), thus a substantially rectangular general shape 48 when it is in its second position, each rib being arranged in the corners of said rectangular shape. This positioning of the pivot axes of the ribs B₁, B₂, B₃, B₄ relative to the mast allows the frame to be inserted into a rectangularly shaped case as shown in FIG. 2. This further allows the frame 12 to be more compact in the direction of the small dimension of the oblong shape.

Each stretcher F comprises a first end connected to the runner 32, more particularly by a ball-and-socket connection, as illustrated in FIGS. 8, 10 and 11, and a second end connected by a pivotal connection to the second part 42 of the first segment S₁ of each rib B₁. More particularly, the first end of each stretcher F carries a spherical portion 50 engaged in a cavity of complementary shape of the runner 32. The second end of each stretcher F is pivotally inserted between two arms 52 of the second part 42 of the first segment S₁ of each rib B₁. As can be seen, each stretcher F also comprises elastic means which, in the particular case illustrated in the figures and better visible in FIGS. 8, 10 and 11, take the form of an elastic tongue 54. This elastic tongue 54 is carried by the first end of the stretcher F and extends towards the second end of the stretcher F so as to form an angle with the stretcher F. In other words, the tongue 54 moves away from the stretcher F towards the second end of the stretcher F. Thus shaped, this tongue 54 allows to exert a elastic force against the mast 18, more particularly against the tube portion 18₁ of the mast 18, which allows to induce a pre-deployment of the frame 12 from its first closed position thus allowing the user to more easily access the runner and to be able to manipulate it to move it from its first position to its second position.

According to the present document, the specific connection of each stretcher F by a pivot connection to the runner 34 and to a second part 42 of a segment S₁ of a rib B₁, which second segment 42 is able to pivot relative to a first segment 40 hinged on an oblique pivot axis, allows the ribs B₁, B₂₃, B₄ to move away from each other from the first position (FIGS. 4, 5 and 6) to the second position (FIGS. 9, 10 and 11).

The runner 34 (FIG. 11) comprises a first upper annular portion 56 comprising the housings or cavities for receiving the spherical parts 50 and a lower portion 58 comprising a recess for receiving a high spring 60 for locking the runner 34 in the second position of the frame 12.

We now refer to FIG. 12 which represents the rib B₁ connected to the mast 18 and to the runner according to the aforementioned means. The different parts of a rib are illustrated in FIG. 13, this rib being able to be indifferently the rib B₁, B₂, B₃ or B₄

Each rib comprises n segments S arranged end to end from the first segment S₁ to an n-th end segment S_n, and:

• • for any k∈[2,n−1]
    • the k-th segment S_k is connected to the segment S_k−1 by a pivot axis P_Sk−1/Sk and is connected to the segment S_k+1 by a pivot axis P_Sk/Sk+1,
    • a rod T_k is associated with the segment S_k and is connected by a pivot axis P_Tk/Sk−1 and by a pivot axis P_Tk/Sk+1 respectively, to the segment S_k−1 and to the segment S_k+1
  • so that each segment S_k form together with a rod T_k a deformable parallelogram.

Here, in the case represented in the figures and better visible in FIG. 13, each rib comprises 5 segments S₁, S₂, S₃, S₄, S₅ and it is observed that the segments S₂, S₃ and S₄ respect the above mentioned rule. It can be seen that the rods T₂, T₃, T₄ also comply with the aforementioned rule.

Similarly, the frame comprises a first rod T₁ pivotally connected to the stretcher by a pivot connection P_T1/F and pivotally to the second segment S₂ by a pivot pin R_T1/S2.

In order to realize a deployment and closing of each rib, the pivotal axes P_Tk/Sk−1, P_Sk/Sk−1 and P_Tk−1/Skk are positioned relative to each other so that said pivot axes are substantially aligned, the pivot axis P_Sk/Sk−1 being positioned between the pivot axis P_Tk/Sk−1 and the pivot axis P_Tk−1/Sk.

In FIG. 13, it can be seen that each k-th rod T_k comprises a bulge R_Tk for receiving the pivot axis P_Tk+1/Sk and the pivot pin P_Sk/Sk+1 when the frame is in its first position (see also FIG. 3). Furthermore, each k-th segment S_k comprises a bulge R_Sk for receiving the pivot axis R_Tk/Sk−1 when the frame is in its first position. Also, said first rod T₁ comprises a bulge R₁ for receiving the pivot axis P_S1/S2 and the pivot axis P_T2/S1.

The present document thus relates to a deployable frame comprising one or more ribs. Thus, a configuration with four ribs makes it possible to deploy a canvas around one end of the mast and thus protect the user. This frame is advantageously portable. It could also be used as a non-mobile structure by a user moving around on foot and could, for example, be transportable and serve as an umbrella. Also, in another embodiment, the frame may comprise two ribs symmetrical to each other relative to plane A or plane C (FIG. 4). In such an embodiment, the fabric could comprise a first free edge and a second free edge which could be connected to a vertical structural element(s), such as a vertical plane, for example a wall, the mast being vertically oriented and arranged adjacent to or spaced from said vertical elements. The plane A or C may be vertically oriented and perpendicular to a vertical plane passing through the vertical elements. The deployment of the two ribs can thus lead to the two ribs moving away from the vertical structural elements, the fabric thus being angularly stretched from a first vertical element, a first rib, a second rib to the second vertical element. In this way, it can be imagined that the canvas has the shape of half a canvas of FIG. 1. Such a deployable structure could be used at a terrace of a drinking establishment, for example, for tables arranged next to a wall.

The fabric can be made of an elastically deformable material so that the fabric is little or lowly stretched when the frame is in its first closed position.

Reference is now made to FIGS. 14 to 17, which illustrate a waterproof casing 62 accommodating the previously described frame 12 but which could accommodate a different frame not described herein so that the description of the waterproof casing 2 may or may not be combined with the characteristics of the frame 12. This is evident from the disclosure made in the “Introduction to the Invention” section.

The parts identical to those previously described will not be described again and will bear the same references without limiting the content of the following description to the embodiment of FIGS. 1 to 13.

The case 62 shown in FIGS. 14 to 17 thus includes a handle element 64 and a case 66 which differ from those previously described in that the watertight attachment of these two parts is performed differently. Nevertheless, the dimensional description characteristics (length, width, and thickness) made previously and the consequences resulting therefrom are applicable to this case. This casing 62 is suitable for receiving any type of frame and in particular the one 12 described above.

The case 66 includes a fixed portion 68 and a first movable member 70a and a second movable member 70b which are movable between a first position for sealingly locking the handle element 64 with the case 66 and a second unlocking position for disengaging the handle element 64 from the case 66. The first movable member 70a and the second movable member 70b are symmetrical to each other with respect to a plane containing the longitudinal axis of the mast 18. The fixed portion 68 of the case 66 includes a first wall 68a and a second wall 68b extending in the direction of length 11 and thickness 13 and a third 68c and a fourth wall 68d extending in the direction of width 12 and length 11 or height. The first wall 68a and the second wall 68b are parallel to each other. The same is true of the third 68c and fourth 68d walls. These walls 68a, 68b, 68c, 68d are connected to each other by a bottom wall 68e or top wall.

The handle member 64 includes a first wall 64a and a second wall 64b extending in the direction of length 11 and thickness 13 and a third 64c and a fourth wall 64d extending in the direction of width 12 and length 11 or height. The first wall 64a and the second wall 64b are parallel to each other. The same is true of the third 64c and fourth 64d walls. These walls 64a, 64b, 64c, 64d are connected to each other by a bottom wall 64e or top wall.

One or more sealing pieces such as seals may be interposed between the case 66 and the handle member 64 but are not shown. The walls of each pair of third walls 66c, 64c of the case 66 and the handle member 64 and fourth walls 66d, 64d of the case 66 and the handle member 64 are aligned together in the longitudinal direction and provided to be placed end to end as seen in particular in FIG. 14.

Each movable member 70a includes a first web 72a and a second web 72b connected to each other by a wall element 74 (FIGS. 15 and 16A). This wall element 74 may be shaped to be substantially aligned with the first wall 66a for the first movable member 70a and with the second wall 66b for the second movable member 70b. The description made with reference to one movable member is also valid for the other of the movable members.

In order to guide the first 70a and second 70b moving parts, guiding means are provided on the protective device.

Thus, each web 72a, 72b comprises a housing 76 having a first curved portion 76a, i.e., extending along an arc of a circle, which is connected at one end to a portion 76b oriented along the longitudinal axis L (FIGS. 15B and C). This housing 76 is here more particularly a slot, i.e. a housing passing through the web 72a, 72b. It is understood that a non-through housing, i.e. a groove, could provide the same guiding function. This being the case, the slot allows each guiding rod to be fixed to the third wall and the fourth wall of the case as shown in the figures. According to the present document, a lower rod or second rod 78 is engaged by one end in the housing 76 of the first web 72a and for the other opposite end in the housing 76 of the second web 72b. This second or lower rod 78 is fixed to the third 66c and fourth 66d walls of the case 66. In FIG. 15C, it is observed that there is a means of attachment 77 of the lower rod 78 of the first veil 72a of the first movable member 70a to the third wall 66a, whereas this means of attachment has been removed (for ease of reading) from this figure (but exists) with respect to the lower rod 78 of the first veil 72a of the second movable member 70b.

The wall element 74 of each movable member 70a, 70b may comprise a first upper hook 80 capable of cooperating by elastic snap-fastening with a first hook 82 of complementary shape of the fixed portion 68 of the case 66 when the movable member 70a, 70b is in its first position so as to lock said movable member 70a, 70b on the fixed portion 68 of the case 66 along the longitudinal direction (FIGS. 15A, 16 and 17B). It is observed that the upper end or first end of the wall element 74 of the movable member 70a, 70b is slidably guided along the longitudinal direction L by means of an upper rod 84 or first rod, the ends of which are fixed to the third 66c and fourth 66d walls of the fixed portion 68 of the case 66 and which is engaged in a slot 86 of the first end or upper end of the wall element 74 (FIGS. 16a and 17B).

Furthermore, each movable member 70a, 70b comprises a second lower hook 88 formed at a second end of the wall element 74 along the longitudinal direction L. This second hook 88 is adapted to elastically snap-fastening with a second hook 90 of complementary shape of the handle element 64 when the movable member is in its first position so as to block a movement of the movable member 70a, 70b along a direction perpendicular to the longitudinal direction L.

After the deployable frame is moved to its first closed position, the opening of the case 66 is presented at the notch 34 of the frame 12 and the frame 12 is inserted into the case 66 until the third walls 66a, 64a of the case 66 and the handle member 64 and the fourth walls 66d, 64d of the case 66 and the handle member 64 come into contact, optionally via one or more seals. The movable members 70a, 70b being in their second unlocking position (not shown), these are displaced by pivoting about the first rods so as to come into an intermediate position in which the second rods 78 are able to slide longitudinally in the second portions 76b of the housings 76, the first rods 84 then also being allowed to slide in the slots 86 of the first ends of the wall elements 74 of the movable members 70a, 70b.
