DETAILED DESCRIPTION OF THE DISCLOSURE

[0054] FIG. 1 shows an example of a demarcation installation 100 of the disclosure for demarcating two areas for playing a sport, in particular a racket sport. Such an installation is particularly adapted to playing badminton outdoors. The installation may be placed in a deployed position in which it stands on the ground and enables the sport to be played, and a folded position in which it is stowed and can be moved. The installation has a base 2, a first bow 4, a second bow 6, and a link 8 extending between the two bows.

[0055] The base is made up of first, second, third, fourth, fifth, sixth, seventh, and eighth connection elements 10, 20, 30, 40, 50, 60, 70, and 80, together with a first main connector 102 and a second main connector 104, and with a first connection part 120 and a second connection part 122.

[0056] In this example, the connection elements are rods of the tent-pole type that may be made of fiberglass or of plastics material. These rods are substantially identical, such that their diameters and their lengths are similar. The first connection element 10 has a first end 10a and a second end 10b opposite from the first end. Likewise, each connection element has a first end and a second end opposite from the first end. For reasons of readability, these ends are not referenced in the figures.

[0057] As can be seen in FIG. 1, the first main connector 102 and the second main connector 104 are configured to rest on the ground. In this non-limiting example, the first main connector 102 and the second main connector 104 are identical.

[0058] An example of a first main connector 102 is shown in FIG. 2. This main connector 102 is a molding comprising first, second, third, and fourth sleeves 106, 108, 110, and 112. Each of these sleeves has an axis. The axes of the sleeves meet at a connection point 114. The third and fourth sleeves 110 and 112 are configured to rest on the ground and they lie in a plane Q substantially parallel to the ground when the installation 100 is placed in the deployed position. With reference to said plane Q, the third and fourth sleeves 110 and 112 form an obtuse angle at a point coinciding with the connection point 114.

[0059] The first and fourth sleeves 106 and 112 are substantially coplanar in a first substantially vertical plane when the installation 100 is in the deployed position. In addition, with reference to said plane, the first sleeve 106 slopes relative to the fourth sleeve 112, and thus relative to the horizontal, in an outward direction at an angle lying in the range 15 to 45, and preferably in the range 25 to 35.

[0060] Likewise, the second and third sleeves 108 and 110 are substantially coplanar, in a second substantially vertical plane when the installation 100 is in the deployed position. In addition, with reference to said plane, the third sleeve 108 slopes relative to the first sleeve 110, and thus relative to the horizontal, upwards at an angle lying in the range 15 to 45, and preferably in the range 25 to 35.

[0061] A first top opening 102a, a second top opening 102b, a first bottom opening 102c, and a second bottom opening 102d are arranged respectively in the first, second, third, and fourth sleeves 106, 108, 110, and 112. These openings are configured to receive the second ends of the first, second, third, and fourth connection elements 10, 20, 30, and 40, respectively.

[0062] As can be seen in FIG. 1, in order to place the installation 100 in the deployed position, the user inserts the second ends of the connection elements in the corresponding openings of the main connectors 102 and 104.

[0063] In this example, since the connection elements are all identical and in the form of rods, they may be interchanged and turned round freely in order to be assembled to the main connectors in any direction. In this way, the user does not encounter any difficulty in connecting the connection elements to the main connectors and the installation can be set up easily.

[0064] In non-limiting manner, the first and second main connectors 102 and 104 are substantially identical such that they can likewise be interchanged freely. The second main connector 104 has the same characteristics as the first main connector 102, and is therefore not described in detail. The second main connector 104 also has a first top opening, a second top opening, a first bottom opening, and a second bottom opening, configured to receive the fifth, sixth, seventh, and eighth connection elements 50, 60, 70, and 80, respectively.

[0065] The slope of the first and second sleeves 106 and 108 relative to the fourth and third sleeves 112 and 110 of the first main connector 102 determines the angles of inclination of the first and second connection elements 10 and 20 relative to the horizontal. Thus, the second connection element 20 likewise slopes at an angle lying in the range 15 to 45 relative to the third connection element 30 and relative to the horizontal plane Q. In the same manner, the first connection element 10 likewise slopes at an angle lying in the range 15 to 45 relative to the fourth connection element 40 and relative to the horizontal plane Q.

[0066] In the same manner, the slopes of the first and second sleeves of the second main connector 104 determine the angle of inclination of the fifth and sixth connection elements 50 and 60 relative to the horizontal. Thus, the fifth connection element 50 likewise slopes at an angle lying in the range 15 to 45 relative to the eighth connection element 80. In the same manner, the sixth connection element 60 slopes at an angle lying in the range 15 to 45 relative to the seventh connection element 70.

[0067] Furthermore, an example connection part 120, 122 is shown in FIG. 3. This connection part comprises a first sleeve 126 and a second sleeve 128, each having a respective axis. The axes of these sleeves form an acute angle, substantially equal to 40. A first opening 120a and a second opening 120b are arranged respectively in the first sleeve 126 and in the second sleeve 128. This connection part 120, 122 also has a third sleeve 129 opposite from the other two sleeves 126 and 128 with an axis lying on a bisector of the angle between the axes of the other two sleeves 126 and 128. A third opening 120c is likewise formed in this third sleeve 129. The first and second openings 120a and 120b are configured to receive the first ends of respective connection elements. The first connection part 120 and the second connection part 122 are substantially identical.

[0068] With reference once more to FIG. 1, it can be seen that the first connection part 120 connects together the fourth and seventh connection elements 40 and 70. The second connection part 122 connects together the third and eighth connection elements 30 and 80. These connection parts 120 and 122 are configured to rest on the ground.

[0069] In this example, the third, fourth, seventh, and eighth connection elements 30, 40, 70, and 80 are coplanar in the plane Q and they rest on the ground so as to form a substantially horizontal stand. In addition, the main connectors 102, 104 and the connection parts 120, 122 are configured so that the third connection element 30 is substantially parallel to the seventh connection element 70 and the fourth connection element 40 is substantially parallel to the eighth connection element 80. In addition, and in non-limiting manner, the set of four connection elements acts as a lozenge-shaped stand. These connection elements provide the installation with stability.

[0070] Furthermore, the installation also has first and second secondary connectors 130 and 132 for connecting the bows 4 and 6 to the base 2. In this non-limiting element, the secondary connectors 130 and 132 are substantially identical to the first and second connection parts 120 and 122, and likewise comprise three sleeves, each having a respective axis, with openings being formed therein. The secondary connectors thus likewise have three openings.

[0071] The first secondary connector 130 connects together the first connection element 10, the sixth connection element 60, and the first bow 4. In particular, the first end 41 of the first bow 4 is inserted into the third opening of the first secondary connector. The second secondary connector 132 connects together the second connection element 20, the fifth element 50, and the second bow 6. Likewise, a first end 61 of the second bow 6 is inserted in the third opening of the second secondary connector 132.

[0072] FIG. 4 is a face view of the installation of the disclosure. In this figure, it can be seen that the two bows 4 and 6 are spaced apart, sloping towards each other and extending upwards from the first and second secondary connectors 130 and 132. The first and second bows 4 and 6 include respectively a first fixing portion 138 and a second fixing portion 140.

[0073] In this non-limiting example, the first bow 4 and the second bow 6 are each constituted by a bottom segment 4a, 6a, and a top segment 4b, 6b that are connected together by connection means 11, 13.

[0074] Furthermore, the link 8 extends between the two bows 4, 6 and more precisely between the two fastening portions 138 and 140. These fastening portions are situated at the free ends 42 and 62 of the bows 4 and 6 remote from the first ends 41, 61 of the bows. In non-limiting manner, the fastening may be performed by inserting the free ends 42 and 61 of the bows 4 and 6 into pockets 142 and 144 arranged at opposite ends of the link 8.

[0075] In this example, the link 8 is a net that extends between the two fastening portions 138 and 140. The net 8 holds the two bows 4 and 6 under tension bending them upwards and in convex manner. In return, the bows keep the net under horizontal tension between the two fastening portions 138 and 140.

[0076] FIG. 5 shows the installation 100 seen in profile, while FIG. 6 shows the installation 100 seen from above. In these figures, it can be seen that the first main connector 102 and the second main connector 104 lie on either side of a vertical plane P containing the net 8. Furthermore, the plane P passes through the secondary connectors 130 and 132 and via the connection parts 120 and 122.

[0077] The main connectors 102 and 104 are arranged so as to be substantially symmetrical relative to the plane P. The distance between the plane P and each of the main connectors 102 and 104 is equal to substantially half the length of one connection element 10, 20, 30, 40, 50, 60, 70, or 80. This distance is quite short, such that the stand extends only a short distance into each of the two playing areas demarcated by the installation. In addition, considered in projection onto the vertical plane P containing the net, the main connectors are arranged substantially halfway along the length of the net.

[0078] Furthermore, the plane P constitutes a plane of symmetry for the demarcation installation 100, and in particular for the base 2. It can be seen in particular that the plane P constitutes a plane of symmetry for the stand of lozenge-shape constituted by the third, fourth, seventh, and eighth connection elements 30, 40, 70, and 80. In particular, the intersection between the plane P and the plane Q in which the third, fourth, seventh, and eighth connection elements 30, 40, 70, and 80 extend constitutes substantially one of the diagonals of the lozenge formed by these connection elements.

[0079] In non-limiting manner, the connection elements 10, 20, 30, 40, 50, 60, 70, and 80 are connected to the main connectors 102 and 104, to the connection parts 120 and 122, and to the secondary connectors 130 and 132 in releasable manner. In this way, the user can put the installation into its folded position easily, and the compactness of the installation, once folded, is improved. In order to fold the installation 100 it is appropriate to release the ends of the connection elements so as to disconnect them from each of the connectors and the connection parts. Thereafter the user disconnects the bottom segments 4a, 4b and the top segments 6a, 6b from the connection means 11, 13.

[0080] Furthermore, the first secondary connector 130 and the first and sixth connection elements 10 and 10 may be held to one another by first elastic means serving to keep them together when they are disconnected. Likewise, the second secondary connector 132 and the second and fifth connection elements 20 and 50 may be held to one another by second elastic means serving to keep them together when they are disconnected. In addition, the first connection part 120 and the fourth and seventh connection elements 40 and 70 are held to one another by a first elastic member for keeping them together when they are disconnected. The second connection part 122 and the third and eighth connection elements 30 and 80 are held to one another by a second elastic member serving to keep them together when they are disconnected. Because of these elastic means of members, the connection elements and the connectors or connection parts are easily connected together and it is not possible for them to be come separated. Operations of setting up and taking down the installation are thus very simple.
