TECHNICAL FIELD OF THE INVENTION

[0001] The field is that of the devices of protection of the bad weather and/or the sun. STATE OF THE ART

[0002] 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.

[0003] 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.

[0004] 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.

[0005] 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.

[0006] 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

[0007] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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 S<1 >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<S>k−1</S>k and is connected to the segment S<k+1 >by a pivot axis P<S>k</S>k+1, a rod T<k >is associated with the segment S<k >and is connected by a pivot axis P<T>k</S>k−1 and by a pivot axis P<T>k</S>k+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<T>k for receiving the pivot axis P<T>k+1</S>k and the pivot axis P<S>k</S>k+1 when the frame is in its first position. Each k-th segment S<k >comprises a bulge R<S>k for receiving the pivot x is P<T>k</S>k- 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.

[0022] The pivot axes P<T>k</S>k−1, P<S>k</S>k−1 and P<T>k−1</S>kk 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<S>k</S>k−1 being positioned between the pivot axis P<T>k</S>k−1 and the pivot axis P<T>k−1</S>k.

[0023] The frame may comprise a first rod T<1 >pivotally connected to the stretcher and pivotally connected to the second segment S<2 >by a pivot axis P<T>1</S>2.
