Description

Title of the invention: Platform for a tent and capable of being placed on the roof of a vehicle. FIELD OF THE INVENTION

[0001] The present invention relates to outdoor activities, and in particular to camping. More specifically, the present invention relates to a support platform for a tent intended to be attached to the roof of a motor vehicle. TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0002] Roof tents, generally installed on the roof of a motor vehicle, have the advantage of protecting their occupants from moisture. These tents rest on a horizontal platform attached to the roof of a vehicle, for example, by means of roof bars.

[0003] It is thus known from the prior art of integrated systems such as that described in document FR 2434054 AL In particular, this document discloses a system provided with a box fixed on the roof of a motor vehicle and housing a roof tent.

[0004] The trunk comprises, in this respect, a lower shell and an upper shell, each cooperating at its respective periphery to form a closed unit. The roof tent, housed within the trunk, is itself secured, at its edges, to the respective peripheries of the upper and lower shells. Thus, opening the trunk by moving the upper shell allows the tent to be deployed.

[0005] Such an integrated system nevertheless offers its occupants a limited living space.

[0006] In order to overcome this problem, it has been possible to propose, in particular in the document FR 2853869 Al, to implement a box enclosing a fold-out platform in order to provide a larger support surface for the roof tent. The proposed system uses hinges 2 and 3 allowing the articulation of panels IA and IB relative to panel IC ([Fig. 2] of document FR 2853869 Al). However, the structure proposed in this document requires the implementation of stiffening elements, in particular crossbeams 4. These complicate the installation of the platform.

[0007] One object of the present invention is therefore to propose a roof tent platform offering a surface area greater than the platforms known in the art.

[0008] Another objective of the present invention is to provide a simpler platform for use. BRIEF DESCRIPTION OF THE INVENTION

[0009] The objectives of the present invention are, at least in part, achieved by a support platform for a tent, the support platform being capable of being fixed to the roof of a vehicle, the support platform comprising at least one support module, the support module comprising:

[0019] According to one embodiment, for each sliding means, when the second pin is in the stop position, the first pin is upstream, according to the direction of deployment, of the first entry.

[0020] According to one embodiment, for each sliding means, the junction groove and the second straight groove are arranged to allow passage from the first intermediate position to a second intermediate position for which the first pin is opposite the first entry and the useful face is inclined relative to the upper wall, the passage from the first intermediate position to the second intermediate position being executed by guiding the second pin in the junction groove and then in the second straight groove according to the direction of deployment.

[0021] According to one embodiment, for each sliding means, the first bypass is arranged to allow the passage of the panel from its second intermediate position to its deployed position by guiding the first pin in the first entry towards the terminal housing, the second pin during said passage from the second intermediate position to the deployed position, being guided in the second straight groove in a direction opposite to the direction of deployment.

[0022] According to one embodiment, for each slide means, the terminal housing and the second straight groove are arranged to maintain the first and second pins at an equal distance from the top wall, respectively, when the panel is in the deployed position.

[0048] The present invention relates to a deployable support platform intended to form a surface on which a tent can rest.

[0049] In this respect, the present invention relates to a support platform for a tent, the platform being capable of being fixed to the roof of a vehicle, the platform comprising at least one support module, the support module comprising:

[0050] - a parallelepiped-shaped support formwork provided with an upper wall, of a lower wall, connected laterally by two side walls, the formwork comprising an opening, on a front face perpendicular to the upper wall, and delimited in part by an edge, called upper edge, of the upper wall;

[0051] - a panel which comprises, according to a first direction going from a first edge towards a second edge opposite the first edge, a retention section and a useful section, which comprise, oriented towards the upper wall, respectively, a retention face and a flat useful face, the retention face being recessed from the useful face and separated from the latter by a support stop perpendicular to the useful face, the panel being in sliding connection by its retention section with the side walls, via two sliding means, so as to be able to slide, parallel to a sliding direction perpendicular to the front face, between two positions called, respectively, the stowed position and the deployed position, the stowed position being a position for which the panel is entirely housed in the supporting formwork, while the deployed position is a position for which the panel is against its support stop,against the upper edge, so that the outer face of the upper wall and the useful face of the useful section are flush with each other.

[0052] Figure 1 is a schematic representation of a support platform 1 conforming to the principles of the present invention set forth below. In particular, in this Figure 1, the support platform comprises a single support module 10. The support module 10 comprises, in this respect, a support formwork 20 and a panel 30 which is capable of adopting either a stowed position or a deployed position.

[0053] The stored position, illustrated in [Fig.1], corresponds to a position in which the panel 30 is entirely housed in the support formwork 20. The deployed position, as illustrated in [Fig.2], is a position in which a section called the useful section of the panel 30 is outside the support formwork 20 and has a face, called the useful face, positioned coplanarly with an external face of a wall, called the upper wall of said formwork 20.

[0054] Particularly advantageously, and as illustrated in [Fig. 3], the support platform 1 can comprise two support modules 10, referred to respectively as the main module 10a and the side module 10b. In particular, the main module 10a and the side module 10b are connected by pivot means. It will become clear later that this configuration with two support modules, referred to as the extended configuration, makes it possible to offer a larger surface area for a tent, as illustrated in [Fig. 4].

[0055] Thus, according to a first embodiment of the present invention, the support platform 1 comprises a support module 10.

[0056] The support module 10 includes a support formwork 20 (illustrated in [Fig.5]) of parallelepiped shape. More specifically, the support formwork 20 is provided with two walls, referred to respectively as the upper wall 21 and the lower wall 22. These two walls are also connected laterally by two side walls 23 and 24. The support formwork 20 also includes an opening 25 on a front face 26 of said support formwork 20 and perpendicular to the upper wall 21. More specifically, the opening 25 is delimited by edges, accessible from the front face 26, of the upper wall 21, lower wall 22, and side walls 23 and 24. In this respect, the edge of the upper wall 21, which partially delimits the opening, is hereinafter referred to as the upper edge 27. Insofar as the support formwork 20 has a parallelepiped shape, it is understood that the opening 25 is rectangular.The support formwork 20 may also include a base, opposite the front face.

[0057] The side walls 23 and 24 according to the present invention may be monolithic. Alternatively, the side walls 23 and 24 may have a layered form. In particular, according to this latter configuration, the side walls 23 and 24 may each comprise an outer layer and an inner layer. The outer layer of a given side wall, accessible externally to the support formwork 20, may in particular be mechanically fixed to both of the upper and inner walls. The inner layer, parallel to the outer layer and affixed to one of its faces inside the formwork, can be mounted to slide and be removed from the supporting formwork. The remainder of this description of the invention will be limited to mentioning side walls without further details. These side walls, in accordance with the foregoing, may be either monolithic or laminated.

[0058] The support module 10 also includes a panel 30 intended to cooperate with the support formwork 20. In particular, the panel 30 is in sliding connection with the support formwork 20 so as to be able to slide between two positions which will be described in more detail later in the statement. The panel 30 comprises, in a first direction going from one of its edges, called first edge 30a, to another of its edges opposite the first edge and called second edge 30b, a retaining section 31 and a useful section 32 of constant thickness and greater than the thickness of the retaining section 31. The retaining section 31 and the useful section 32 each comprise a face oriented towards the upper wall 21 and called, respectively, retaining face 33 and useful face 34. More particularly, the retaining face 33 is set back from the useful face 34 so as to form a stop, called support stop 35, separating said faces 33 and 34 and perpendicular to the useful face 34 ([Fig.6]). .

[0059] As previously stated, the panel 30 is connected to the support formwork 20 by its retaining section 31 via two sliding means. More specifically, the two sliding means are configured to allow the panel 30 to slide, in a direction perpendicular to the front face and referred to as the sliding direction, between two positions, respectively called the stowed position and the deployed position. In this respect, the stowed position (illustrated in [Fig. 1]) is a position in which the panel 30 is fully housed within the support formwork 20, while the deployed position (illustrated in [Fig. 2]) is a position in which the panel 30 rests against the upper edge 27 by the support stop 35, and such that the outer face of the upper wall 21 and the usable face 34 are flush with each other.The surface thus formed by the outer face of the upper wall 21 and the usable face 34 is flat and suitable for the installation of a tent. Positioning the support platform on the roof of a motor vehicle thus allows the tent occupants to be isolated from moisture over a considerable area compared to platforms known in the prior art. Furthermore, the support platform 10 according to the present invention is relatively simple to use and can be deployed quickly.

[0060] In a particularly advantageous manner, the two slide means are arranged symmetrically with respect to each other with respect to a plane perpendicular to the upper wall 21 and the front face 26. Furthermore, and again advantageously, each slide means can be supported by an inner face of one of the side walls and by a lateral side of the facing retaining section.

[0061] According to an advantageous embodiment of the present invention, a sliding means, supported by an inner face and a facing lateral side, comprises a pair of pins formed on said lateral side and a guide groove 40 formed on said inner face. More particularly, the pair of pins comprises, in the first direction, a first pin 36a and a second pin 36b separated by a first distance DI ([Fig. 6]). The guide groove 40 extends linearly from a first end 40a to a second end 40b in a direction of movement from a rear face of the formwork opposite the front face to said front face. The guide groove 40 is notably configured to cooperate with the pair of pins and thus allow the sliding of the panel 30.

[0062] Advantageously, each slide means may comprise, associated with its guide groove 40 and in an order defined by the direction of deployment, a first branch 41a and a second branch 41b configured to cooperate, respectively, with the first pin 36a and the second pin 36b of the slide means considered ([Fig. 7]). In particular, and in accordance with the present invention, the first branch 41a and the second branch 41b are configured to allow, after sliding the support panel along the guide grooves in the direction of deployment, the displacement of said support panel towards the upper wall 21 and its positioning against the upper edge 27 by the support stop 35.

[0063] More specifically, and in accordance with the foregoing, the first branch 41a and the second branch 41b are formed on the inner face between the guide groove 40 and the upper wall 21. In particular, the first branch 41a opens into the guide groove 40 through a first inlet 42a, while the second branch 41b opens into the guide groove through a second inlet 42b. In this respect, the first inlet 42a and the second inlet 42b are separated by a second distance D2 that is less than the first distance DI.

[0064] As illustrated in [Fig. 8], the first branch 41a may include, extending from the guide groove 40, a curved groove 43a and a first straight groove 44a parallel to the guide groove 40 and in line with the curved groove 43a. Furthermore, in the example illustrated in [Fig. 8], the curved groove 43a is oriented such that the first straight groove 44a extends from the curved groove 43a in a direction opposite to the direction of deployment. Also, the first straight groove 44a terminates in a recess oriented towards the guide groove 40 so as to form a terminal housing 45a capable of receiving the first pin 36a.

[0065] Still in relation to [Fig.8], the second derivation 41b may include, a connecting groove 43b and a second straight groove 44b parallel to the guide groove 40, the connecting groove 43b joining the guide groove 40 and the second straight groove 44b.

[0066] Each sliding means may also include, at the second end 40b of its guide groove 40, a stop, referred to as a sliding stop 40c, against which the second pin 36b is intended to abut after the panel 30 has slid, in the direction of deployment, from its stowed position to a first intermediate position. As illustrated in [Fig. 9], the first intermediate position is a position in which at least the support section 34 of the panel 30 is extracted from the support formwork 20 and the second pin 36b is abutting against the sliding stop 40c. Furthermore, the sliding stop 40c is arranged so that when said second pin is abutting against the sliding stop, it is also opposite the second inlet 42b of the joining groove 40.

[0067] Furthermore, insofar as the distance D2 is less than the distance Dl, it is clear that when the second pawn 36b is opposite the second entry, the first pawn 36a is upstream, according to the direction of deployment, of the first entry 42a.

[0068] The junction groove 42b and the second straight groove 44b are arranged to allow passage from the first intermediate position to a second intermediate position (illustrated in [Fig. 10]). In particular, the second intermediate position, illustrated in [Fig. 10], is a position in which the first pin 36a is opposite the first inlet 42a while the working face is inclined relative to the upper wall 21. The passage from the first intermediate position to the second intermediate position is thus accomplished by guiding the second pin 36b in the junction groove 43b and then in the second straight groove 44b according to the direction of deployment.

[0069] The first branch 41a is advantageously arranged to allow the panel 30 to move from its second intermediate position to its deployed position (illustrated in [Fig. 11]) by guiding the first pin 36a of the first inlet 42a to the terminal housing 45a. During this movement from the second intermediate position to the deployed position, the second pin 36b is guided in the second straight groove 44b in the opposite direction to the deployment direction. It is thus understood, without further ado, that the terminal housing 45a and the second straight groove 44b are arranged to maintain the first pin 36a and the second pin 36b at an equal distance from the upper wall 21 when the panel 30 is in the deployed position.

[0070] Advantageously, and as illustrated in [Fig. 6], the retaining section comprises, from the first edge to the support stop 35, a beveled portion 33a and a support portion 33b. In particular, the beveled portion 33a has a thickness that increases from the The first edge 30a is supported by a bearing portion 33b, which has a constant thickness less than that of the support section. In this respect, the bearing portion 33a is configured to bear against an inner face of the upper wall 21 when the panel 30 is in its deployed position. Advantageously, the beveled portion 33a extends over a length L from the first edge and is designed to remain clear of the inner face of the upper wall 21 as the panel moves from its second intermediate position to its deployed position. More specifically, the beveled portion prevents any contact between the retaining section and the inner face of the upper wall as the panel moves from its second intermediate position to its deployed position.

[0071] The support platform 1 may also include two locking means, in particular locking pins 46 ([Fig.9], [Fig.10] and [Fig.11]), configured to hold each first pin 36a in its terminal housing 45a and insertable into an opening provided in either of the side walls.

[0072] Advantageously, the support platform 1 may include foldable, adjustable-length legs 50 arranged on one face of the panel opposite the working face ([Fig. 12]). Said face opposite the working face may include longitudinal grooves 51 in which the legs are housed when folded (and thus allow the panel to be stored in the support casing).

[0073] It is further understood that the support module also includes locking means for adopting either a locked position or a retracted position. The locked position is, in this respect, a position for which the locking means allow the panel to move from its stowed position to its deployed position. A person skilled in the art, based on their general knowledge, can devise any type of locking means capable of fulfilling the functions thus described. However, and advantageously, it may be considered to implement a hatch configured to close the opening.

[0074] The invention also relates to a second embodiment of the support platform 1. According to this second embodiment, the support platform 1 comprises two support modules, referred to respectively as the main module 10a and the lateral module 10b. These two support modules may essentially reproduce all or part of the characteristics of the support module described in relation to the first embodiment.

[0075] According to this second embodiment, the main module 10a and the lateral module 10b are linked to each other by a pivot joint (for example, via a hinge), each by one of their lateral walls. The pivot joint allows these two modules to adopt either a folded state ([Fig. 13]) or an unfolded state ([Fig. 14]). The folded state is, in particular, a state in which the two upper walls are positioned one against the other while the unfolded state is a state in which the external faces of two upper walls are coplanar.

[0076] According to this second embodiment, the main module 10a can be configured to be fixed to the roof of a motor vehicle.

[0077] According to this second embodiment, the support platform may include a longitudinal element 60 ([Fig. 16]) configured to fill a gap between the main module panel, referred to as the main panel 30a, and the side module panel, referred to as the side panel 30b. The longitudinal element includes a face, referred to as the complementary face, coplanar with the usable faces of the main and side panels when the latter are in the deployed position ([Fig. 15]). The longitudinal element 60 may advantageously include a rib surmounted by a flat section to present a T-shaped cross-section. The rib is configured, in particular, to fill the gap between the main panel and the side panel, while the flat section may be configured to bear against the usable faces of the usable sections of the panels.

[0078] Similar to the main panel and the side panel, additional foldable and adjustable-length feet 70 are arranged on an external face of the lower wall of the formwork supporting the side module. This external face may also include longitudinal grooves 71 in which the additional feet 70 are housed when folded.

[0079] Regardless of the embodiment considered, the support platform can be attached to the roof of a motor vehicle. In particular, in the first embodiment, the support frame is installed on the roof of the motor vehicle. This installation may involve the use of a roof rack. Using the support platform, for example for setting up a tent, then requires deploying the panel. After deployment, the usable face of the panel, together with the outer face of the upper wall, forms a flat surface on which a tent can be installed. The legs 50 can also be unfolded to reinforce the structure.

[0080] In the second embodiment, the support platform is attached to the roof of the motor vehicle by the support frame of the main module. The deployment of the main and side panels is preceded by the transition of the two support modules from their folded to their unfolded state. In this latter state, the outer faces of the two upper walls are coplanar, and both the main and side panels can be deployed. The installation of the feet and other supports reinforces the structure.

[0081] Of course, the invention is not limited to the embodiments described and alternative embodiments can be made without departing from the scope of the invention as defined by the claims.
