Definitions

  • the present disclosure relates to the field of sports equipment for use on a playing area, and in particular for racket sports.
  • the disclosure relates more precisely to a demarcation installation that is to be deployed on the ground so as to define two playing areas.
  • the demarcation installation of the disclosure must be transported easily and must be set up and taken down quickly, while nevertheless being sufficiently stable to ensure that the sport can be played comfortably on ground that is not smooth or outdoors in the presence of a light breeze.
  • Removable demarcation installations are known, such as that described in Document EP 0 595 815, made up two uprights with a net extending between them.
  • the uprights are respectively connected to two connectors extending substantially in the same plane as the net.
  • Two leg members extend on either side of each of the connectors in order to hold the installation on the ground.
  • leg members need to be particularly solid in order to support the installation as a whole.
  • the weight of the installation is particularly great, which makes it difficult to transport, once folded up.
  • An object of the present disclosure is to propose a demarcation installation for playing areas that remedy the above-mentioned drawbacks.
  • a particular object of the disclosure is to reduce the bulk of the installation and its fabrication costs.
  • the demarcation installation must also present great stability in order to enable the sport to be played on ground that is not smooth or outdoors in the presence of a light breeze.
  • the disclosure provides a demarcation installation for demarcating two playing areas, the installation comprising:
  • the main and secondary connectors serve to connect together the connection elements and the bows in releasable manner.
  • the installation of the disclosure can thus be placed in a deployed position in which it rests on the ground and enables a racket sport to be played, and a folded position in which it can be stowed and moved easily.
  • connection elements in order to place the installation in the deployed position, the user connects the connection elements to the associated main connectors. The user then connects together the first and sixth connection elements and connects them with the first bow by means of the first secondary connector. The user also connects together the second and fifth connection elements and connects them with the second bow by means of the second secondary connector.
  • the assembly constituted by the connection elements and by the main and secondary connectors constitutes a base configured to support the two bows. The user can then set up the link between the fastening portions of the first and second bows.
  • the first and second bows are flexible, such that fastening the link to the fastening portions of the bows serves to put the bows and link simultaneously under tension, thereby deploying the installation on the ground.
  • the bows are thus kept under tension in an arcuate position towards the sky by means of the link.
  • the bows keep the link under tension substantially horizontally between the two fastening portions.
  • the plane containing the link is vertical when the installation is placed in the deployed position and is resting on the ground.
  • connection elements extend from one of the main connectors so as to rest on the ground in order to form a stand serving to support the installation.
  • the main connectors strengthen the installation transversely and enable its stability to be improved.
  • connection elements are rigid.
  • the main connectors extend on either side of the vertical plane containing the link, and the lateral footprint of the installation as considered in this plane is particularly small.
  • the first and second main connectors extend on either side of said vertical plane containing the link, in a manner that is symmetrical relative to the plane. This symmetry serves to improve the equilibrium and thus the stability of the installation.
  • connection elements can thus be separated and stowed independently, so as to improve the compactness of the installation once folded.
  • the connection elements and the connectors may be placed in a stowage bag in order to be transported.
  • the first and second main connectors are configured to rest on the ground, whereby these connectors constitute points of contact for the installation with the ground that are arranged on either side of the vertical plane containing the link. These connectors prevent the installation from tilting in a direction extending transversely to said plane, e.g. when a user strikes the installation. The transverse stability of the installation is thus improved.
  • connection elements are substantially identical. In this way, all of the connection elements present substantially the same dimensions.
  • One advantage is to enable a single mold to be used for fabricating all of the connection elements, thereby reducing fabrication costs.
  • connection elements can be interchanged in any way, thereby facilitating setting up and deploying the installation.
  • connection elements are configured to rest on the ground.
  • connection elements form a stand enabling the installation to be supported and stabilized.
  • connection elements resting on the ground may be ballasted or fastened to the ground by means of tent pegs possibly U-shaped pegs, so as to further improve the stability of the installation of the disclosure.
  • the third, fourth, seventh, and eighth connection elements are rods, each having at least a first end.
  • rods are of transverse dimensions that are considerably smaller than their lengths.
  • they may be made of fiberglass or of plastics material.
  • first ends of the fourth and seventh connection elements are connected together by a first connection part and the first ends of the third and eighth connection elements are connected together by a second connection part.
  • the third connection element extends between the first main connector and the second connection part.
  • the fourth connection element extends between the first main connector and the first connection part.
  • the seventh connection element extends between the second main connector and the first connection part.
  • the eighth connection element extends between the second main connector and the second connection part.
  • the vertical plane containing the link also contains the first and second connection parts.
  • the vertical plane containing the link constitutes a plane of symmetry for the installation, thereby strengthening the equilibrium of said installation.
  • connection element and the seventh connection element are substantially parallel, and the fourth and eighth connection elements are substantially parallel.
  • the third, fourth, seventh, and eighth connection elements form a parallelogram.
  • these connection elements arranged in a parallelogram increase the equilibrium of the installation and prevent it from tilting in either direction.
  • the first, second, fifth, and sixth connection elements slope relative to a plane containing the third and seventh connection elements.
  • this plane containing the third and seventh connection elements is substantially horizontal when the installation is placed in its deployed position, such that the first, second, fifth, and sixth connection elements slope upwards relative to the horizontal.
  • the first and sixth connection elements constitute support means for the first bow and the second and fifth connection elements constitute the support means for the second bow.
  • the first, second, fifth, and sixth connection elements slope relative to said plane at an angle lying in the range 15° to 45°.
  • This angle of inclination is selected in such a manner as to place the link at a height that is appropriate for playing the racket sport.
  • This angle of inclination is selected in particular as a function of the length of the bows.
  • the first main connector has a first top opening, a second top opening, a first bottom opening, and a second bottom opening configured to receive the first, second, third, and fourth connection elements respectively.
  • the second main connector 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 respectively.
  • a connection element in an opening in one of the main connectors, said connection element is secured to said connector.
  • the angle of inclination of the opening determines the angle of inclination of the connection element inserted in said opening.
  • the angle of inclination between the top first opening and the bottom second opening of the first main connector is the same as the angle of inclination between the first connection element and the fourth connection element.
  • the angle of inclination between the top second opening and the bottom first opening of the first main connector is the same as the angle of inclination between the second and third connection elements.
  • bottom and top should be considered relative to a direction that is substantially vertical.
  • the bottom openings of the main connectors are arranged substantially horizontally such that the third, fourth, seventh, and eighth connection elements extend substantially in a horizontal plane. Furthermore, the top openings of the main connectors slope relative to the bottom openings, such that the first, second, fifth, and sixth connection elements slope relative to the horizontal.
  • connection elements and the bows are connected to the main and secondary connectors in disconnectable manner.
  • the first secondary connector and the first and sixth connection elements are held to one another by first elastic means, enabling them to be kept together when they are disconnected, and the second secondary connector and the second and fifth connection elements are held to one another by second elastic means, enabling them to be kept together when they are disconnected.
  • first connection part and the fourth and seventh connection elements are held to one another by a first elastic member, enabling them to be kept together when they are disconnected, and the second connection part and the third and eighth connection elements are held to one another by a second elastic member, enabling them to be kept together when they are disconnected.
  • the first, third, fourth, and eighth connection elements form a lozenge. It can be understood that the first, third, fourth, and seventh connection elements are then of the same length.
  • An advantage in this configuration is that the vertical plane containing the link constitutes a plane of symmetry for the lozenge, such that the main connectors are arranged symmetrically relative to the plane. Once more, the equilibrium of the installation is strengthened.
  • the first, third, fourth, and eighth connection elements extend only a little into the playing areas demarcated by the installation. The overall size of the installation in the deployed position is thus reduced.
  • the link is a net.
  • the advantage is to make it convenient to play a racket sport and in particular to be certain whether the ball or the shuttlecock has indeed gone over the link.
