Description

Title of the invention: Modular installation for multidisciplinary activities.

[0001] The present invention relates to a modular installation for multidisciplinary activities.

[0002] It is known for installations specifically designed for an activity, such as tennis by forming a net, basketball by creating a backboard, or football or handball by modeling a goal. It is also known for recreational installations, such as the construction of a playhouse. These installations are intended primarily, but not exclusively, for children.

[0003] Thus, it is common for multiple facilities to clutter the living space or garden of a house. Having several facilities dedicated to a specific sport that are not interchangeable also represents a significant expense for users.

[0004] Due to the design and materials used, children can design and assemble most of the installations themselves.

[0005] Moreover, such installations are difficult or even impossible to dismantle, which makes their removal difficult when not in use.

[0006] Document FR3028422 A1 describes a modular sports game using a telescopic pole. Three disciplines can be played: football, tennis, and basketball. The game comprises a telescopic pole with a tapered upper end extended by a cord that holds a ball or a tennis ball. Its base is attached to a flexible element connecting it to a base.

[0007] In the basketball version, two lower elements of the pole and the base are used. A restraint, threaded onto the pole and then fitted onto two of the four diametrically opposed protrusions, neutralizes the pole's oscillation. A basket is fitted onto the top of the pole. A collar limits the penetration of the upper element into the lower one. The game according to this document can be used particularly outdoors, on clay, grass, asphalt, or packed sand, for example, on a beach.

[0008] In the ball and tennis ball version, the game includes a telescopic pole whose end is tapered and extended by a cord at the end of which is attached either a ball or a tennis ball.

[0009] It follows that the installation described in this document is a compromise allowing the practice of several sports but is not specifically dedicated to a particular sport after a specific adaptation but preferably easy to implement.

[0010] Elements such as the telescopic pole are retained for all activities hence a limitation on the customization of the installation for the activity carried out.

[0011] Document CN211752320 U describes a sports facility serving as a multifunctional children's football goal. The device comprises a horizontally arranged crossbar and vertically arranged uprights under both ends of the crossbar. A component connects each upright to the crossbar.

[0012] The length of the crossbar and the parts is adjustable and held in position by a locking element, as is the height of the uprights, with various height points fixed by tightening screws. Each upright has feet resting on the ground. The width of the goal can be changed. A net can be hung on the structure, or the structure can be used as a support for badminton, tennis, or volleyball, and can also be used to hang a ball frame via the connection mechanism for shooting or practicing shooting.

[0013] On the other hand, for this installation described in this document, it seems difficult to modify it to give it a three-dimensional shape, which restricts its scope of application.

[0014] The problem underlying the present invention is to design a multidisciplinary activity facility that is modular by being composed of standard construction elements that can be easily connected to each other and then dismantled after use.

[0015] To this end, the present invention relates to a modular installation for multidisciplinary activities, comprising several tubular bars made of flexible plastic or foam, advantageously polyurethane foam, and removable connecting pieces ensuring contact with at least one tubular bar by interlocking, of which at least one set of female connecting pieces or at least one set of forks, each of the female pieces having at least two hollow receiving ends projecting outwards from the piece, each of said at least two ends receiving inside a longitudinal end of a respective tubular bar in order to connect at least two tubular bars together, each of the forks having a fork head with at least two widely spaced points to receive a longitudinal end of a tubular bar inside the fork head, the fork having a male end extending opposite to the fork head,The installation is equipped with foot pieces, each foot piece comprising a flat base with a hollow end piece protruding outwards, receiving within it a longitudinal end of a tubular bar which then forms the upright of the installation.

[0016] The technical effect achieved is ease of assembly and reduced installation cost, the installation being essentially composed of tubular bars that can perform various different functions. All the elements are separable from one another so that the installation, once disassembled, takes up little space.

[0017] The connecting parts are form-fitting, that is to say, for female connecting parts, the connection is established by contact between hollow receiving ends and longitudinal ends of tubular bars received in the ends.

[0018] Such a connection by form is faster to assemble than a connection by force or interposed elements such as by tightening knobs as proposed for example in document CN211752320 U.

[0019] Indeed, the connection is made by pushing the longitudinal end of a tubular bar into a hollow end piece without needing an additional locking means.

[0020] The configuration of a connecting piece at the head of the fork is suitable for connecting one tubular bar to another tubular bar with the possibility of disengaging the bar inserted in the fork, which is desirable in the case of a vaulting bar arranged transversely to two vertical bars each forming a riser, the vaulting bar having to be able to dissociate from a riser bar when touched by the jumper.

[0021] Advantageously, a first part of the female connecting pieces comprises at least three hollow receiving tips projecting outwards from the connecting piece, said at least three tips extending perpendicularly to each other in three different directions to each other or at least two tips extending in opposite directions or forming a bend between each other.

[0022] The fact that each of the female parts can have three or more receiving ends makes it possible to design a three-dimensional installation, which was not possible in document CN211752320 U. Multiple configurations of the installation are thus made possible.

[0023] Such a female connecting piece is particularly well suited to making a corner of an embodiment of a three-dimensional installation.

[0024] Advantageously, the removable connecting parts of the installation comprise at least one set of male connecting parts, each of the male parts having at least two male tips projecting outwards from the male connecting part, each of said at least two male tips penetrating into one longitudinal end of a respective tubular bar in order to connect at least two tubular bars together.

[0025] These male connecting parts can serve as an alternative for part of the female parts, the principle of the connection being substantially the same by contact between the male end inserted into a tubular bar.

[0026] Advantageously, the male connecting piece comprises a flat base having two opposite faces joined by an edge, a first face having at least one male end and the second face opposite the first face having at least one male end extending in the opposite direction to at least one male end of the first face.

[0027] Advantageously, tubular bars are pierced by a longitudinal series of recesses, a diameter of each recess being configured to receive and retain a male end of a male connecting piece.

[0028] This allows for a transverse connection enabling the selection of connection heights with another element, for example another tubular bar, via a connecting piece. A possible application is for a vaulting bar adjustable between various positions on two vertical tubular bars forming a support, or for mounting a basketball backboard at a higher or lower height on at least one tubular bar forming a support, the height being relative to the user's height.

[0029] Advantageously, the connecting parts of the installation include inserts having grooves or holes for receiving portions of tubular bars or auxiliary construction elements in order to connect at least two tubular bars or at least one tubular bar and one auxiliary construction element or two auxiliary construction elements together.

[0030] Advantageously, the connecting parts of the installation include plugs or inserts each formed of a head extended by a rod, the rod being configured to penetrate into a longitudinal end of a tubular bar or into a recess present on the tubular bar and the head being configured to butt against the longitudinal end of the tubular bar or a wall of the recess.

[0031] These connecting pieces meet the criterion of ease of assembly without tightening and without interposition of an additional locking means.

[0032] Advantageously, each foot piece includes stabilizing wings extending externally from the base by extending in the same plane as the base.

[0033] The stabilizing wings, advantageously deployable to be retracted into the body when reinforcement of the stability of the foot piece is not required, help to the stability of the foot piece.

[0034] Advantageously, the stabilizing wings internally contain a heavy material such as sand, which stabilizes the foot piece. This reinforces the stability of each foot piece and, consequently, of the entire installation.

[0035] Advantageously, the installation is configured to make a jumping pit or a rugby goal with two tubular bars each forming upright connected by a connecting piece with a tubular bar forming crossbar, each tubular bar forming upright resting on a foot piece and carrying a longitudinal series of recesses for a height positioning of the tubular bar forming crossbar.

[0036] Advantageously, the installation is configured to form a goal cage with two tubular bars, each forming an upright, connected by a connecting piece with a tubular bar forming a crossbar, each tubular bar forming an upright resting on a foot piece, three tubular bars forming a base being connected to each other to form a U with a bottom and two arms, the U being open towards the tubular bars forming each upright, the longitudinal ends of the two tubular bars forming the base materializing the

[0037] branches of the U being connected by a connecting piece to a respective foot piece, the installation comprising a net extending all around the U being fixed to the tubular bars forming the base, to the tubular bars forming the upright and to the tubular bar forming the crossbar.

[0038] Advantageously, the installation is configured to make a basketball backboard with two tubular bars each forming a post and each connected to a foot piece, an upper portion of each tubular bar forming a post carrying via a connecting piece a backboard with a basketball hoop, the backboard, on a face opposite to the face carrying the basketball hoop, comprising two sleeves sliding respectively on a tubular bar forming a post, the tubular bars carrying a longitudinal series of recesses for a height positioning of the backboard, the installation comprising a counterweight having a mass and two base bars whose longitudinal ends are connected by a connecting piece to a respective foot piece.

[0039] Advantageously, the installation is configured to make a tennis net with three tubular bars, each forming a post and resting on a foot piece, a net being stretched by connecting pieces between two of the three tubular bars, which then form net posts at each of the longitudinal ends of the net, the third bar, shorter than the two longitudinal bars forming posts, being located at mid-length of the net and supporting the net via a connecting piece.

[0040] Advantageously, the installation is configured to make at least one children's playhouse, with, for said at least one playhouse, four tubular bars each forming upright being connected to each other via four connecting pieces and four tubular bars forming crossbars and supporting two roof panels being connected by a joining piece pinching them against each other at an angle between the two panels, planks or imitation bricks being superimposed one on top of the other with their width in a vertical position to make walls of the playhouse.

[0041] The attached drawings illustrate the invention:

[0052] In the figures, in particular figures 5 to 10 showing a modular installation 1 of multidisciplinary activities for a series of elements such as tubular bars 2, 2a, 2b each forming uprights, crossbeams or floor bars, only one element per category is referenced.

[0053] The same applies to a series of similar connecting parts 3, 3a, 3b, 3c, but what is stated for a part or a referenced element is valid for all parts of the same category.

[0054] It should also be borne in mind that the figures are given by way of example and are not limiting to the invention. They constitute schematic representations of principle intended to facilitate understanding of the invention and are not necessarily to scale with practical applications. In particular, the dimensions of the various elements illustrated are not representative of reality.

[0055] For example, in [Fig.4], the connecting piece in the form of a plug comprising a head extended by a rod can be reduced in size to penetrate into one of the lateral recesses carried by a tubular bar forming a riser, in which case the rod has a diameter corresponding to the diameter of the recess.

[0056] This type of connecting piece can also be larger in size to pass through a tubular bar forming a riser in order to secure it with a tubular crossbar as shown under reference 3c for example in [Fig.6] for a football goal, in which case the rod has a diameter corresponding to the internal diameter of the tubular bar 2b in which the rod fits.

[0057] In what follows, reference is made to all the figures taken in combination. When reference is made to one or more specific figures, these figures are to be taken in combination with the other figures for the recognition of the designated numerical references.

[0058] With reference to all the figures, the present invention relates to a modular installation 1 for multidisciplinary activities.

[0059] Multidisciplinary activities can be sports activities such as high jump, hurdle jump, installation 1 forming a jumping pit, football, rugby or handball by forming a goal, volleyball or tennis by forming a net 6 with adjustable height or basketball by forming a support for a basketball backboard 17.

[0060] The activities can also be recreational activities, especially for children, with the installation 1 forming a hut or a support for various suspended objects.

[0061] The installation 1 comprises several tubular bars 2, 2a, 2b made of flexible plastic or foam, advantageously polyurethane foam. These bars have the advantage of being lightweight when the disassembled installation 1 is transported. These bars also have the advantage of not injuring users in the event of unwanted contact while ensuring the mechanical strength of the installation 1.

[0062] The installation 1 includes, for ensuring the connection between various tubular bars 2, 2a, 2b or with only one connecting bar, removable connecting pieces 3, 3a, 3b, 3c, 3d.

[0063] The 3d part which is a fork head is not shown individually in the figures but is referenced in [Fig.5] illustrating a jumper.

[0064] A non-limiting set of connecting pieces 3, 3a, 3b, 3c is shown in figures 1a to 1e, 2a to 2d, 3 and 4.

[0065] These removable connecting pieces 3, 3a, 3b, 3c, 3d ensure contact with several tubular bars 2, 2a, 2b, in which case the connecting pieces 3, 3a, 3b, 3c, 3d perform the connection between at least two tubular bars 2, 2a, 2b.

[0066] Connecting pieces 3c can also ensure contact with a single tubular bar 2, 2a, 2b by being fitted into the tubular bar 2, 2a, 2b, for example like a rod 15 having a head 16 of abutment against the tubular bar 2, 2a, 2b.

[0067] The connecting pieces 3, 3a, 3b, 3c, 3d can also be used to connect other elements than tubular bars 2, 2a, 2b, for example auxiliary construction elements 11, for example roof sections as shown in [Fig.9] illustrating a cabin.

[0068] The connection with the tubular bar or bars 2, 2a, 2b is made by simple fitting either of the connecting piece into one or more tubular bars 2, 2a, 2b or of a portion of the or each tubular bar 2, 2a, 2b into the connecting piece 3, 3a, 3b, 3c, 3d.

[0069] Therefore, there is no need for an additional tightening means such as screwing with a knob to ensure the connection and lock it.

[0070] Among the connecting pieces 3, 3a, 3b, 3c, 3d the present invention proposes to use a set of connecting pieces 3 female, therefore receiving a portion of at least one tubular bar 2, 2a, 2b, most frequently a longitudinal end portion of at least one tubular bar 2, 2a, 2b.

[0071] Female connecting pieces 3 are shown in figures 1 to 1.

[0072] As an alternative or complement, the present invention proposes to use a set of 3d fork heads.

[0073] Linking pieces in fork heads are shown in [Fig.5] to support between two tubular bars 2 forming upright a tubular bar 2a forming cross with detachment of the tubular bar 2a forming cross at the slightest shock applied against it.

[0074] Each of the female connecting pieces 3 has at least two hollow receiving ends 14 projecting outwards from the outside of the piece. Each of the ends 14 is adapted to receive inside it a longitudinal end of a respective tubular bar 2, 2a, 2b in order to connect at least two tubular bars 2, 2a, 2b together.

[0075] There may be several types of 3 female connecting pieces.

[0076] A first part of the female connecting pieces 3 may include at least three hollow receiving tips 14 projecting outwards from the connecting piece.

[0077] Fig. 1a shows a female connecting piece with five tips. Fig. 1b shows a female connecting piece with four tips and Fig. 1e shows a female connecting piece with three tips.

[0078] A second part of the female connecting pieces 3 may comprise fewer than three hollow receiving ends 14. Thus, Figures Id and le show respectively a female connecting piece with two ends, angled for [Fig.ld] and in line with each other in [Fig.le].

[0079] Thus the tips 14 can extend perpendicularly to each other in three directions different orientations to each other, as shown in figures a to le. Such female connecting pieces 3 can make corner pieces in installation 1.

[0080] Alternatively, the second part of the female connecting pieces 3 may include two hollow receiving tips 14 projecting outwards from the connecting piece, the two tips extending in opposite directions or forming a bend between them, as shown in figures Id to le.

[0081] In an optional but advantageous configuration mode, shown only in [Fig.5], the connecting parts of the installation may include forks with a 3d fork head with at least two widely spaced points to receive a longitudinal end of a tubular bar inside the 3d fork head.

[0082] In addition, the 3d fork head may have a male end extending in opposition to the points.

[0083] The 3d fork head can connect a horizontal and transverse bar to two vertical tubular bars, each forming a riser, while its male end penetrates one of the vertical tubular bars.

[0084] A connecting piece forming a 3d fork head is thus used for fixing the horizontal bar forming, for example, a jumping bar for each tubular bar forming an upright.

[0085] In addition to female connecting pieces or fork-shaped connecting pieces 3d, for ease of assembly in certain configurations of the installation 1, with reference in particular to figures 2a to 2d, the connecting pieces of the installation 1 may include insert pieces or inserts 3a having grooves 13, 13a or holes 12 for receiving portions of tubular bars 2, 2a, 2b or auxiliary construction elements 11.

[0086] These insertion pieces or inserts 3a can connect together at least two tubular bars 2, 2a, 2b or at least one tubular bar 2, 2a, 2b and an auxiliary construction element 11.

[0087] It is also possible that such insert pieces 3a connect two auxiliary construction elements 11 together such as roof sections 11, as shown in [Fig.9].

[0088] [Fig. 2a] shows an insert piece in the shape of a rectangular parallelepiped having at least one orifice 12 on each of its cross-section faces. These orifices 12 can receive a longitudinal end of a tubular bar 2, 2a, 2b.

[0089] Fig. 2a shows tubular bars 2, 2a, 2b of smaller diameter than the other figures, but such an insert piece 3a can be used for the tubular bars 2, 2a, 2b of the installation 1 according to the present invention, these tubular bars being shown in particular in figures 5 to 10.

[0090] Figures 2b and 2c each show an insert piece 3a having at least one groove 13, two grooves 13, 13a for the [Fig. 2c], the grooves 13, 13a being of different configuration.

[0091] Fig. 2d shows a rounded insert piece 3a with a flat face comprising two receiving ports 12.

[0092] The removable connecting pieces 3, 3a, 3b, 3c, 3d of the installation 1 may also include at least one set of male connecting pieces 3b, each of the male pieces having at least two male tips 14a projecting outwards from the male connecting piece 3b.

[0093] Each of said at least two male tips 14a can penetrate inside a longitudinal end of a respective tubular bar 2, 2a, 2b in order to connect at least two tubular bars 2, 2a, 2b together.

[0094] A non-limiting embodiment of such a male connecting piece 3b is shown in [Fig. 3]. The male connecting piece 3b may comprise a flat base having two opposite faces joined by an edge.

[0095] A first face may have at least one male end 14a and the second face opposite to the first face may have at least one male end 14a extending in the opposite direction to that of said at least one male end 14a of the first face.

[0096] It is possible to use a male connecting piece 3b as a fork head described previously. In this particular application, it may be a single tubular bar that is inserted between the male ends 14a for retention, rather than tubular bars penetrated by the male ends 14a. In this particular application, the male ends 14a act as the fork head tips.

[0097] Particularly suitable for tubular bars 2, 2a, 2b serving as vertical uprights and in order to adjust the height of a tubular bar 2, 2a, 2b extending transversely to the tubular bars 2 each forming upright, tubular bars 2, 2a, 2b can be pierced by a longitudinal series of recesses 19. This can be seen in particular in figures 5 and 7 taken in combination.

[0098] For positioning the tubular bar 2a forming a crossbar, a diameter of each recess 19 can be configured to receive and hold a male end 14a of a male connecting piece 3b or a fork head end 3d.

[0099] The tubular bars 2, 2a, 2b can be of different diameters. Indeed, for example, a longitudinal bar forming a vaulting bar does not need to be as large as a longitudinal bar forming a vertical.

[0100] The female ends 14 or male ends 14a of the female connecting parts 3 or male ends 3b can be cylindrical with a circular cross-section or with flats, having diameters appropriate to their function.

[0101] As shown in particular in Figures 4 and 7, the connecting parts of the installation 1 may include insert parts or inserts 3c in the form of plugs, each formed of a head 16 extended by a rod 15. The rod 15 may be configured to enter a recess 19 present on the tubular bar 2, 2a, 2b and the head 16 can be configured to abut against a wall of the recess.

[0102] Alternatively, as shown in particular in Figures 4 and 6, the rod 15 can be configured to penetrate a longitudinal end of a tubular bar 2, 2a, 2b and the head 16 can be configured to abut against the longitudinal end of the tubular bar 2, 2a, 2b, at the [Fig.6] a basic tubular bar 2b after the rod has passed through a tubular bar 2 forming a riser.

[0103] With reference in particular to figures 5 to 10, to ensure its stability on the ground, the installation 1 can be provided with foot pieces 4. Each foot piece 4 can include a flat base carrying a hollow end piece projecting outwards from the foot piece 4 receiving inside a longitudinal end of a tubular bar 2 thus forming the upright of the installation 1.

[0104] Each foot piece 4 can be tilted so that the installation 1 can rest on an inclined floor. This can be done with a joint between the hollow end piece and the base of the foot piece 4.

[0105] Each foot piece 4 may include stabilizing wings extending outwards from the base in the same plane as the base. These stabilizing wings are not shown in the figures.

[0106] The stabilizing wings can internally contain a heavy material such as sand stabilizing the position of the foot piece 4 by making it heavier.

[0107] Six embodiments of the installation 1 will now be described, each dedicated to a specific sporting or recreational activity, which is not exhaustive.

[0108] As a first embodiment shown in [Fig.5], the installation 1 can be configured to make a jump with two tubular bars 2 each forming upright connected by a connecting piece 3d in the form of a fork head with a tubular bar 2a forming crossbar, this in an easily removable manner.

[0109] A 3d fork head with two points is preferred to allow more freedom of detachment of the tubular bar 2a forming a cross member relative to the associated tubular bar 2 forming a stile, such a fork head 3a only supporting the tubular bar 2a forming a cross member.

[0110] Such a connecting piece could also be a male connecting piece 3b with four ends 14a, one end of which is opposite the other three, in the configuration shown previously in [Fig. 3]. The end opposite the other three penetrates the associated tubular bar 2 forming a vertical support, while the three other ends, with the same orientation, receive between them a tubular bar 2a forming a crossbar. The tubular bar 2a forming a crossbar can thus be dislodged from the space between said at least three ends when subjected to an impact, in particular when struck by a jumper.

[0111] Such a 3D connecting piece can also be replaced by a connecting piece supporting the tubular bar 2a forming a crossbar while allowing at least one freedom of the tubular bar 2a forming a crossbar upwards or laterally to be released from the connection during an impact.

[0112] Each tubular bar 2 forming a upright can rest on a foot piece 4 and can carry a longitudinal series of recesses for a height positioning of the tubular bar 2a forming a cross member, a series of recesses 19 being visible in [Fig.7],

[0113] As a second embodiment shown in [Fig.6], the installation 1 can be configured to make a goal cage with two tubular bars 2 each forming upright connected by a female connecting piece 3 bent at two ends with a tubular bar 2a forming crossbar, each tubular bar 2 forming upright being able to rest on a foot piece 4.

[0114] Three tubular bars 2b forming a base, therefore intended to be supported against the ground, can be connected together by forming a U with a bottom and two arms, the U being open towards the tubular bars 2 each forming a riser.

[0115] The longitudinal ends of the two tubular bars 2b forming the base of the branches of the U can be connected by a connecting piece 3c to a respective foot piece 4, the connecting piece advantageously being an insert in the form of a plug with head and stem as shown in [Fig.4].

[0116] The installation 1 may include a net 6 extending all around the U being fixed to the tubular bars 2b forming the base, to the tubular bars 2 forming the upright and to the tubular bar 2a forming the crossbar.

[0117] As a third embodiment shown in [Fig.7], the installation 1 can be configured to make a basketball backboard 17 with two tubular bars 2 each forming a riser and each connected to a foot piece 4.

[0118] An upper portion of each tubular bar 2 forming a riser can carry via a connecting piece a panel 17 with a basketball hoop 18.

[0119] The panel 17, on a face opposite to the face carrying the basketball hoop 18, may include two sleeves sliding respectively on a tubular bar 2 forming a riser.

[0120] The tubular bars 2 forming uprights can carry a longitudinal series of recesses 19 for a height positioning of the panel 17.

[0121] In addition, in order that the entire basketball backboard 17 does not fall towards the user, the installation 1 may include, behind the installation 1, a counterweight 20 comprising a mass and two base bars 2b whose longitudinal ends can be connected by a connecting piece 3c to a respective foot piece 4, as shown in [Fig.7].

[0122] As a fourth embodiment shown in [Fig. 8], installation 1 can be configured to make a tennis net 6 with three tubular bars 2 each forming a riser and each resting on a foot piece 4.

[0123] A net 6 can be tensioned by connecting pieces 3c, advantageously in the form of a plug-forming insert as shown in [Fig.4], between two of the three tubular bars 2 which then form net posts at each of the longitudinal ends of the net 6. The third upright bar is shorter than the two longitudinal posts and can be located at mid-length of the net 6 and support the net 6 via a connecting piece.

[0124] As a fifth embodiment shown in [Fig.9], the installation 1 can be configured to provide at least one children's playhouse.

[0125] For the playhouse or each playhouse, four tubular bars 2, each forming a upright, can be connected to each other via tubular bars 2a forming a crossbar through four connecting pieces 3, advantageously female connecting pieces with three ends as shown in [Fig.1e].

[0126] The four tubular bars 2a forming a crossbar can support two roof slopes 11 which can be connected by a joining piece 3a, advantageously grooved, pinching the two roof slopes 11 against each other while keeping them adjacent while leaving an angle between the two roof slopes 11.

[0127] Planks or imitations of brick 10, advantageously made of plastic, can be stacked one on top of the other with their width in a vertical position to make walls of the hut.

[0128] As a sixth embodiment shown in [Fig. 10], the installation 1 can be configured to form a rugby goal. This embodiment is similar to the first embodiment concerning the jumping pit. However, since the tubular crossbar 2a must be held securely and is not intended to leave its position when subjected to an impact, the connecting piece linking the tubular crossbar 2a to each of the tubular uprights 2 can preferably be an insert 3c in the form of a plug as shown in [Fig. 4] with a head 16 extended by a rod 15.

[0129] The rod 15 is configured to pass through a laterally recessed tubular bar 2 forming the upright and to penetrate into a longitudinal end of the tubular bar 2a forming the cross member.

[0130] The head 16 can be configured to abut against the wall of the recess made on the tubular bar 2 forming the upright.

[0131] To raise each upright, two longitudinal bars 2 forming uprights can be joined by a female connecting piece 3 to two ends opposite each other, as shown in [Fig.1e].
