The present invention relates in particular to a free-standing post for supporting an article. Such an article may, for example, be a tennis or volleyball net, in which case two free-standing posts are necessary for supporting respective ones of the ends of said net, the two posts being disposed at some distance apart so as to keep the net tensioned. However, such an article may also be constituted by a panel, e.g. constituting a basketball basket or a dartboard. The invention thus also relates to sport game sets equipped with free-standing posts of the present invention.
Free-standing posts are known, in particular from U.S. Pat. No. 6,461,258. That document discloses a sport game set of the volleyball type comprising two free-standing posts and a net. Each free-standing post comprises a base and a pole extending vertically and having its bottom end fastened to the base. At each of its side ends, the net has two cables disposed respectively at the bottom portion and at the top portion of said net. The bottom and top cables pass through the vertical pole. In addition, each free-standing post further comprises at least one bow-shaped flexible blade having its bottom fastened to the bottom end of the pole, on the outside thereof, said bow-shaped flexible blade extending upwards and outwards. In addition, the ends of the bottom and top cables are fastened to that bow-shaped flexible blade. That design makes it possible to tension the net and to keep it at a certain height. In addition, implementing a base makes the post a free-standing post, and offers the advantage of making it possible to set up the sport game set on different types of surfaces such as grass or sand.
An object of the present invention is to provide a free-standing post of design also enabling it to be set up on various types of surface. Objects of the design of the free-standing post of the present invention are also to limit its weight, to limit its manufacturing cost, to facilitate setting it up, to make it compact to stow, and safe in appearance, and thereby to enable the sport game set including one or more free-standing posts to achieve the same objects.
To this end, the free-standing post of the present invention comprises stabilizer means for stabilizing it on the ground, in particular a stabilizer base arranged to stand on a surface such as, for example, tarmac, sand, grass, or some other surface. However, it is possible to make provision for the stabilizer means to be implemented from a plurality of stabilizer bases or the like, in particular of small size, and jointly stabilizing the free-standing post in a more or less vertical position. Such a stabilizer base, or each of such stabilizer bases, is designed, in particular, as described in more detail below through non-limiting examples, to arrange the free-standing post of the invention on any type of surface. However, it is possible to make provision for such stabilizer means to be implemented by means of pegs or stakes co-operating with the other elements of the free-standing post, when the surface on which said free-standing post is installed is of the grass type or of a similar type, into which the pegs or stakes can be driven.
In addition, the free-standing post further comprises a non-rigid element that extends upwards over a height H and has a bottom portion, in particular in the form of guys, which bottom portion is extended by a top portion, in particular by a longitudinal top portion. This non-rigid element, in particular its top portion, is arranged to hold an article, such as, for example, one of the ends of a net, or indeed a panel consisting, for example, of a basketball basket or of a dartboard. First anchor means are arranged between the stabilizer means and the bottom portion of the non-rigid element.
In addition, the free-standing post of the invention further comprises a flexible longitudinal element of length greater than the height H of the non-rigid element, second anchor means being arranged between the bottom end of the flexible longitudinal element and the stabilizer means. Similarly, third anchor means are arranged between the top end of said flexible longitudinal element and the top end of the top portion of the non-rigid element.
Thus, when the first, second, and third anchor means are put in place between the stabilizer means, the non-rigid element and the flexible longitudinal element, the difference in length between said flexible longitudinal element and the non-rigid element makes it possible to bow said flexible longitudinal element, while the non-rigid element is held tensioned more or less vertically between the stabilizer base and the top end of the flexible longitudinal element, in the manner of a bow string. In addition, the stabilizer means make it possible to stabilize both said non-rigid element and the flexible longitudinal element. Holding said non-rigid element tensioned substantially vertically between the base and the flexible longitudinal element also makes it possible to fasten an article, in particular to the longitudinal top portion of said non-rigid element. However, it is also possible to make provision to fasten an article to the bottom portion of said non-rigid element, depending on the design thereof.
Preferably, the non-rigid element of the free-standing post of the present invention is made of a textile material. However, it is possible to consider using other materials such as an elastomer that has little or no extensibility. It can also be understood that the use of such a non-rigid element makes it possible to limit the presence of rigid and generally metal structural elements that are of greater weight than textile materials or indeed than elastomers. This also facilitates stowage.
According to the invention, the stabilizer means, consisting in particular of a stabilizer base, are provided with at least two first fastener systems, the bottom portion of the non-rigid element being constituted by at least two guys, in particular of the strap type, that extend downwards while forming an angle between them, the bottom ends of the guys being provided with second fastener systems co-operating with respective ones of the first fastener systems on the base.
In an embodiment, the stabilizer means consist of a stabilizer base provided with three first fastener systems that are distributed triangularly, the bottom portion of the non-rigid element being made up of three guys, in particular of the strap type, disposed in a tripod configuration. In addition, one of the three guys is disposed extending the longitudinal top portion. This offers the advantage of enabling this guy of the bottom portion to be used for fastening to an article, e.g. to the end of a net used for playing tennis or for playing football-tennis.
According to the invention, the stabilizer means consist of a stabilizer base comprising three stabilizer legs disposed in a star-shaped configuration. Other variants are possible, in particular a stabilizer base comprising a hub and at least two stabilizer legs.
According to the invention, the stabilizer means consist of a stabilizer base further comprising a system for improving its compactness in a stowage mode. It is thus possible to improve the compactness of the free-standing post and therefore of the sport game set made up of one or more free-standing posts.
In the embodiment in which the base comprises three stabilizer legs disposed in a star-shaped configuration, i.e. their proximal first ends are assembled together, the stabilizer legs extending in the same plane while forming angles between them, said proximal first ends are assembled together in pivotally mounted manner so as to enable them to be folded away against one another in said plane, thereby improving compactness.
In the embodiment in which the stabilizer base comprises a hub and at least two stabilizer legs, provision is made for the stabilizer legs to engage into the hub, thereby making it possible to remove the stabilizer legs from the hub so as to group them together for compact stowage.
According to the invention, the flexible longitudinal element is preferably constituted by a flexible tube. In addition, this flexible longitudinal element has a system for reducing its length, also making it possible to improve its compactness when the free-standing post is in stowage mode. Such a length reduction system is, for example, constituted by a flexible tube comprising at least two segments or pole pieces that are suitable for being mutually engaged and for being folded up together. However, it is also possible to consider using a flexible tube that is telescopic.
According to the invention, the stabilizer means consist of a stabilizer base provided with an orifice for receiving the bottom end of the flexible longitudinal element, in particular in the form of a flexible tube. Preferably, this orifice is configured to incline the bottom end of the flexible longitudinal element engaged in said orifice. This offers the advantage of guiding the flexible longitudinal element during assembly of the free-standing post and of contributing to the stability of the flexible longitudinal element in its bowed position, keeping the non-rigid element tensioned vertically. However, it is possible to provide other systems for fastening and guiding the flexible longitudinal element relative to the stabilizer base without going beyond the ambit of the invention. When the flexible element is fastened to and guided on the stabilizer base, it is also conceivable to implement a non-rigid element having its bottom portion and its top portion constituted by a single common strap or the like, the top end of the strap being fastened to the top end of the flexible element and the bottom end of the strap being, for example, fastened to the base, which is anchored in the ground by means of a peg or stake, or is fastened to an additional weight lying on the ground.
In an embodiment of the invention, the top portion of the non-rigid element is constituted by a strap. However, variants are possible, such as, for example, a rope or the like. The same applies for the bottom portion of the non-rigid element. It is also possible to make provision for combinations of straps and of ropes or the like between the bottom portion and the top portion of the non-rigid element.
According to the invention, a fastener system is arranged on the non-rigid element for securing to an article, in particular a panel or one end of a net. Preferably, this fastener system is implemented on the longitudinal top portion of the non-rigid element. However, it is possible to make provision to implement it on the bottom portion of the non-rigid element or indeed on both portions at the same time.
According to the invention, height adjustment means are arranged between the fastener system on the article and the non-rigid element. One purpose of this is to make it possible to adjust the position of the article fastened to the free-standing post, e.g. as a function of the height of the users, who might be children or adults. Another purpose of this is to make it possible to use the same post for fastening to various different types of article, depending on the sport being played.
According to the invention, a system for indicating the height position of the fastener system is arranged on the non-rigid element. This offers the advantage of enabling the article, in particular of the panel or net type, to be positioned appropriately depending on the sport being played.
According to the invention, the stabilizer means further comprise weighing-down means. This offers the advantage of reinforcing the stability of the free-standing post, in particular when the article is of the panel type or indeed of compensating for any forces that might be exerted on the net fastened to the post when, for example, the player leans unintentionally on the net while playing the sport. When the stabilizer means are made up of a stabilizer base comprising a hub and stabilizer legs, it is possible to make provision for the hub to constitute said weighing-down means. It is also possible to make provision for the weighing-down means to be disposed in remote-from-center manner on at least one of the stabilizer legs, in addition to or instead of the hub constituting said weighing-down means. When the stabilizer means consist of a stabilizer base comprising three stabilizer legs disposed in a star configuration and preferably hinged together, the weighing-down means are preferably also disposed in remote-from-center manner on said stabilizer legs. By disposing the weighing-down means in remote-from-center manner, it is advantageously possible to compensate more easily for the torque exerted on the stabilizer base by the article suspended from the non-rigid element and thus, to reduce the size and the weight of the weighing-down means. It is thus also possible to improve the compactness of the free-standing post in the stowed position, and, in addition, to facilitate transporting it in said stowed position.
In addition, in accordance with the invention, such weighing-down means may either be incorporated into the stabilizer means or be removable relative thereto. For example, it is possible to provide small-size weights that are positioned on the distal ends of the stabilizer legs of the stabilizer base.
In addition, the invention provides a sport game set comprising one or more free-standing posts of the invention.
In a first embodiment, this sport game set comprises two free-standing posts and a net provided at its side ends with fastener systems for fastening to the non-rigid elements of the two free-standing posts. It is also possible to provide additional accessories in the sport game set, such as, for example, tennis rackets and balls, badminton rackets and shuttlecocks, volleyballs, footballs, means for delimiting the playing area, or other accessories.
In addition, the net is preferably provided with a width adjustment system, which offers the advantage of making it possible to adjust the width of the court or pitch and the spacing between the free-standing posts as a function of the available playing area or indeed as a function of the sport being played.
In a variant embodiment, the sport game set comprises at least one free-standing post, and at least one panel, which panel is provided on its back face with a fastener system for fastening to the non-rigid element of the free-standing post. For example, the panel may be constituted by a basketball basket, in which case a basketball is provided in the sport game set. It is also possible to provide two free-standing posts and two basketball basket panels in order to constitute a full basketball court.
In addition, such a panel may be a dartboard or an archery target, in which case the sport game set preferably further comprises additional accessories such as darts, a bow and arrows, or other accessories.
More comprehensive sport game sets may also be provided in view of the adaptability of the free-standing post of the invention.
