Definitions

  • the present invention relates generally to the field of sport and more particularly to basketball. It relates in particular to a removable basketball net device.
  • a basketball court requires a number of elements that are essential for the execution of the game.
  • a playing field has at least one hoop reception of the ball, commonly called basket, circle or hoop.
  • the arch has a diameter of approximately 45 centimeters and it is through it that the ball must pass for points to be counted.
  • the hoop is usually mounted on a board, commonly called a backboard, at least at one end of the pitch.
  • the assembly consisting of the arch and the panel is supported by a plinth of a certain height. This height is adjustable according to the age of the players: it can range from 2.60 meters for the youngest players to 3.05 meters for the oldest.
  • a tubular-shaped basketball net of equivalent diameter to that of the hoop, open at each of its ends is generally attached to the hoop.
  • a basketball court requires a number of elements that are essential for the execution of the game.
  • a playing field has at least one hoop reception of the ball, commonly called basket, circle or hoop.
  • the arch has a diameter of approximately 45 centimeters and it is through it that the ball must pass for points to be counted.
  • the hoop is usually mounted on a board, commonly called a backboard, at least at one end of the pitch.
  • the assembly consisting of the arch and the panel is supported by a plinth of a certain height. This height is adjustable according to the age of the players: it can range from 2.60 meters for the older young players at 3.05 meters for the oldest.
  • a tubular-shaped basketball net of equivalent diameter to that of the hoop, open at each of its ends is generally attached to the hoop.
  • the basketball net allows both to facilitate the recovery of the ball and to help confirm the validity of the point in uncertain cases.
  • the basketball net by its shape, allows the ball to be centered and slowed down when it falls, preventing the ball from going too far and thus allowing the players to know in advance where to recover the ball. and put it back into play quickly.
  • the net allows you to have this confirmation by the sound produced in contact with the net, when the ball passes through the hoop.
  • basketball hoops especially outdoors, do not always have a net because they are subject to bad weather and damage.
  • US patents US 5,405,132 and US 5,584,479 disclose a removable basketball net device consisting of a ring made of a plastic and/or metallic material, molded in one piece, having holes for connecting the cords of a net.
  • the structure of the ring of such a device must be sufficiently rigid for said device to be able to hold in position and remain stable on the basketball hoop, which requires a material compromise thus having limited elasticity.
  • This limited elasticity notably prevents bending and/or bending of the device while guaranteeing the maintenance of its shape and its volume after the deformation.
  • This rigidity can cause the ring to break in the event of bending and/or crushing stresses going beyond its elastic limit or even repeated shocks.
  • Such a device is thus cumbersome in particular during its transport but also sensitive to shocks, on the ground for example, and to repeated deformations which may cause early wear due to degradation of the shape of said device, essential to the use made of it.
  • the present invention aims to remedy the aforementioned drawbacks, in particular to improve the flexibility of said device.
  • the invention discloses a removable basketball net device, intended to be installed on a basketball hoop, comprising a ring made of a flexible material on which a basketball net is fixed.
  • said ring is reinforced with a flexible reinforcing rod with a stiffness greater than that of the flexible material of said ring.
  • This design thus makes it possible to have a foldable device that retains its basketball hoop shape after having unfolded it, while ensuring stable support once placed on the basketball hoop and exhibiting good shock absorption.
  • Such a device can thus be easily deformed and therefore transportable due to its small size, by being, for example, stored in a sports bag or else in a dedicated bag.
  • the invention proposes a removable basketball net device, intended to be installed on a basketball hoop containing a hoop.
  • Said device comprises a ring comprising an internal diameter and an external diameter. These two diameters define between them the width of the ring on which a basketball net is fixed.
  • the ring itself consists of a first material having a first modulus of elasticity.
  • Said ring is reinforced with a circular reinforcement rod fixed to the first material.
  • Said reinforcing rod is made of a second material having a second modulus of elasticity which is greater than that of the first material.
  • the diameter of the circular reinforcement rod is closer to the inside diameter of said ring than to the outside diameter.
  • the inner diameter of the hoop is slightly smaller than the diameter of the hoop of the basketball hoop.
  • the outer diameter of said ring is, in turn, greater than the diameter of the hoop of the basketball hoop.
  • the ring has a width of between 4 and 10 centimeters.
  • the first material of the ring can consist mainly of rubber.
  • the circular reinforcing rod can be made of one or more aramid fiber, carbon, glass and/or metal yarns.
  • the circular reinforcement rod is placed inside the first material of said ring.
  • the basketball net can be made from the material of a used fishing net.
  • the figure 1 shows a perspective view of the basketball net device according to the invention illustrating how the device is placed on a basketball hoop.
  • the picture 2 shows a top view of the removable basketball net device according to the invention.
  • the picture 3 shows a sectional view of the device according to the invention, according to section AA defined in picture 2 .
  • the figure 4 shows a top view of the removable basketball net device of the picture 2 in a configuration where said device is folded.
  • the figure 5 shows schematic embodiment views of the removable basketball net device using a tire.
  • said device 100 comprises a ring 110 and a basketball net 120.
  • Said device 100 can be temporarily installed on a basketball hoop 130 containing a hoop 131.
  • the device 100 and a basketball 200 positioned and enclosed in the net 120 of said device 100 are launched together in the direction of the basketball hoop 130
  • the basketball net 120 is large and tight enough to ensure the maintenance of the basketball 200 in said net 120.
  • a knot can be made with the basketball net 120 to reinforce the maintenance of the ball basketball 200 within said device 100.
  • throwing the basketball 200 towards the basketball hoop 200 drives said device 100 over the basketball hoop 130 in order to pass the basketball through the hoop 131.
  • a removable basketball net device 100 in accordance with the invention is illustrated in the figures 2 to 4 .
  • Said device 100 comprises two main elements, namely a ring 110 and a basketball net 120.
  • Said ring 110 of said device comprises an inside diameter 111 and an outside diameter 112. The distance between the inside diameter 111 and the outside diameter 112 defines the width 113 of said ring 110.
  • Said basketball net 120 is fixed over said width 113. The means for fixing the basketball net 120 over said width 113 will be described later in this description.
  • Said ring 110 consists mainly of a first material reinforced by a circular reinforcing rod 114.
  • the first material has a first modulus of elasticity and the reinforcing rod 114 is made of a second material having a second modulus of elasticity.
  • Such a modulus makes it possible to measure the rigidity of a material and/or its tendency to bend.
  • a high modulus of elasticity characterizes a rigid material while a low modulus of elasticity characterizes an elastic material.
  • the second modulus of elasticity is greater than the first modulus of elasticity of the first material.
  • the second material is stiffer than the first material.
  • said ring 110 is made of a first material that is flexible enough to allow said device 100 to bend and/or bend easily without breaking and this, in a reversible manner. Indeed, in the case of use, as illustrated on the figures 3 and 4 , this flexibility provided by this first material can allow said ring 110 on the one hand to at least partially match the shape of the hoop 131 of the basketball hoop 130. This also makes it possible to protect the hands of the players from the hoop 131 when the players enter the basketball 200 directly into the basketball hoop 130 by clinging to the hoop 131 with one or two hands. Indeed, the hoop 131 being outside, it can be damaged or even rusty and can injure a player on this type of action.
  • the first material can also be chosen to promote the adhesion of said device 100 to the basketball hoop 130.
  • the choice of such a first material can also be made to add weight to said device 100 in order to ballast said device 100 in the center of said basketball hoop 130 without risk, for example, of seeing said device 100 fly away following strong gusts of wind or of being sensitive to the slightest stresses applied to the basketball hoop 130.
  • said first material of said ring 110 can consist mainly of rubber.
  • Rubber is an elastomer and elastomers are polymers known to have very good elastic properties supporting significant deformations before rupture. Indeed, elastomers are composed of macromolecules intertwined like a “pile of worms” forming bridges between them. Under stress, the molecules slip except at the level of the bridges giving the elastomer a shape memory. Thus, under mechanical stress, the segments between two bridges stretch. Conversely, when the mechanical stress ceases, the relaxation movements between the molecules bring the molecules back to their configuration and therefore to their initial shape.
  • surface protections can be envisaged, for example, by paint or whatever.
  • the circular reinforcing rod 114 is fixed to the first material constituting said ring 110, preferably inside said first material.
  • a circular reinforcing rod 114 is stiffer than the first material.
  • the diameter of said rod 114 is closer to the inside diameter 111 than to the outside diameter 112 of said ring 110 and is very close to the diameter of the hoop 131, or even of the same size.
  • This preferred embodiment makes it possible to best optimize the holding of said device 100 on the basketball hoop 130. Indeed, this prevents, for example, the flexibility of the first material from causing said device 100 to slide through the hoop. 131 during the passage of the basketball 200.
  • Said upper 114 is made of a second flexible material, making it possible to bend said device 100 into a figure eight and having good mechanical properties, such as, for example, a modulus of elasticity higher than the modulus of elasticity of the first material and a high tensile strength, making it possible to ensure the role of reinforcement within said ring 110.
  • the tensile strength is the resistance of a material to rupture when it is subjected to a tensile force, namely when it is subjected to a stress consisting in stretching it. In other words, it is the maximum stress the material can withstand when stretched before breaking.
  • Said rod 114 thus ensures that said device 100 is held in shape on basketball hoop 130 in the "rest" phase and in the play phase.
  • the second material has a certain flexibility allowing it to be bent into a figure eight by twisting it into a minimum storage configuration, as illustrated in figure 4 .
  • the presence of said circular reinforcement rod 114 thus makes it possible to reinforce said device 100, guaranteeing both the positioning of said device 100 in the center of the basketball hoop 130 and the holding in circular shape of said device 100 without risk of extension or irreversible deformation of said device 100, in particular during successive foldings.
  • said circular reinforcing rod 114 may be made up of one or more aramid fiber yarns, carbon , glass, metal, plastic and/or others having the expected mechanical properties, forming a ribbon or a cable which, when rolled up, forms a circle.
  • aramid fiber yarns carbon , glass, metal, plastic and/or others having the expected mechanical properties, forming a ribbon or a cable which, when rolled up, forms a circle.
  • such materials are suitable for such reinforcement, in particular because of their high mechanical performance.
  • the chains composing it are strongly oriented in the direction of the axis of the fiber, so that the forces of molecular interactions can be exploited for the mechanical resistance.
  • the carbon atoms composing it are agglomerated in long and flat microcrystals aligned parallel to the axis of the fiber.
  • the inside diameter 111 of said ring 110 is sized to allow the passage of a standard 200 basketball.
  • the inside diameter 111 of said ring 110 is substantially close to, or even slightly less than, the diameter of the hoop 131 of the basketball hoop 130, namely of the order of 45 centimeters.
  • it may be between 40 and 44 centimeters.
  • the outer diameter 112 of said ring 110 is sized so that said ring 110 covers the hoop 131 of said basketball hoop 130.
  • the outer diameter 112 of said ring 110 is greater than the diameter of the hoop 131 of the basketball basket 130.
  • the outside diameter 112 can, for example, be between 46 and 54 centimeters.
  • the width 113 of said ring 110 is dimensioned, for its part, to allow said ring 110, once positioned on the basketball basket 130, to cover the entire hoop 131 of said basket 130.
  • the width 113 of said ring 110 is between 4 and 10 centimeters, preferably between 5 and 6 centimeters.
  • the method of manufacturing the removable basketball net device 100 consists, on the one hand, in the manufacture of the ring 110 and, on the other hand, in the fixing of the basketball net 120 on said ring 110 .
  • the manufacture of the ring 110 is made from the reinforcing rod 114 made in the shape of a hoop on which the first material is overmoulded.
  • said ring 110 can be cut from a tire, for example a bicycle tire 320 but also a motorcycle tire 320 or car tire 310, preferably a used tire in order to promote recycling and waste recovery channels.
  • the tires comprise a first flexible material, mainly made of rubber, containing a more rigid circular reinforcement rod called bead wire 330.
  • bead wire 330 makes it possible to hold the tire 310 or 320 in place in a rim by stiffening its internal diameter. so that it does not separate from said rim.
  • the process for manufacturing said device 100 consists first of all in selecting and recovering a tire 310 or 320 whose internal diameter corresponds to the internal diameter 111 desired for the ring 110.
  • the inside diameter 111 of said ring 110 is preferably between 40 and 44 centimeters, which also corresponds to 16 to 18 inch tires. This information can be found on the markings on the sidewall of the tyres.
  • the choice of tire can also be based on its natural curvature. For this purpose, a bicycle or motorcycle tire 320 has a curvature that can better match the shape of the hoop 131 of the basketball hoop 130.
  • the method for manufacturing said device 100 and in particular ring 110 comprises a step consisting in cutting a strip of tire over a width corresponding to the desired width 113 for ring 110 of said device 100.
  • the cut can be made using a finely sharpened knife from sawing the tire placed, for example, on a rotating machine, following the route of the previously defined cutting zone.
  • any other type of cutting tool making it possible to cut a strip of tire such as, for example, a laser cutting machine, an electric saw or even a hammer with a chisel.
  • the cut can be made on different areas of the tire.
  • the cutout 321 can be made at the level of the tread.
  • the cutout 311 can be made only in the sidewall, side part of the tire.
  • a person skilled in the art may use any other tire cutting plane making it possible to obtain the desired dimensioning for said ring 110.
  • a tire strip is obtained , corresponding to said ring 100, mainly made of rubber reinforced with a bead wire 330, corresponding to said circular reinforcing rod 114 within said device 100.
  • the cutout of the tire thus forms the ring 110 of the device 100, the bead wire 330 of the tire constituting the reinforcing rod 114.
  • said method of manufacturing said device 100 includes a final step of fixing the basketball net 120 over the width 113 of said ring 100. Fixing said net 120 over the width of said ring 120 can be done, for example, by clipping or even gluing.
  • the step of attaching said net 120 to said ring 100 consists, initially, in perforating the width 113 of said ring 110, for example, by punching.
  • This perforation step consists of making holes 115 in the width 113 of said ring 110, preferably twelve in number in order to have twelve attachment points for said net 120 corresponding to the twelve loops constituting a standard basketball net 120.
  • Such holes 115 pass through the thickness of said ring 110 and are made to be preferably positioned between the circular reinforcement rod 114 and the outside diameter 112 of said ring close to the inside diameter 111.
  • Such positioning of the holes 115 makes it possible to use the reinforcement rod 114 to also reinforce the holes 115 in order to avoid tearing of said holes 115 when a traction movement is applied to said net 120.
  • a step of introducing a clamp 116 into each of the holes 115 and in each of the loops of said net 120 is placed.
  • the positioning of the clamps 116 on either side of the reinforcement rod 114 thus makes it possible to ensure that said net 120 is held in position without the risk of tearing the ring 110 during its use.
  • clamps of the Serflex ® brand may be used.
  • the person skilled in the art may use any other type of means for fixing the net 120 compatible with the use made of it within said device 100, such as fasteners, staples, or any other means for fixing simple and effective basketball net 112 to the width 113 of said ring 110. It is also possible to imagine fixing means allowing the basketball net 120 to be easily removed from said device 100, in the event that the user would like to change the basketball net 120, such as safety pins for example.
  • said basketball net 120 in order to promote recycling and recovery channels for plastic waste, can be made from the material of a used fishing net.
  • fishing nets consist mainly of plastic material based, for example, on polyamide, polyethylene or polypropylene. Such materials can generate polluting waste for the environment which is, to date, poorly managed and very little valued.
  • the circular reinforcing rod 114 is described as being inside the first material constituting said ring 110.
