Description
- 1 - La présente invention concerne des poteaux de volleyball. La plupart des poteaux de volleyball sont constitués d'un montant tubulaire vertical et d'un support coulissant avec le dit montant où se fixe le filet. Ce dit support coulissant est destiné à régler la hauteur du filet pour les différents niveaux de compétition. Les réglementations concernant la hauteur et la tension du filet sont très strictes et imposent des hauteurs à l'aplomb des lignes latérales et une hauteur au centre du terrain, de plus il y a cinq hauteurs officielles pour les différents niveaux de compétition. Lors du réglage de la hauteur du filet, les poteaux de volleyball existants sont fastidieux à régler, il faut tout d'abord détendre le filet puis régler la nouvelle hauteur de chaque côté, retendre le filet et vérifier les trois hauteurs. Il faut en général s'y reprendre en plusieurs fois pour avoir un filet à une hauteur et une tension conformes à la règlementation. L'objet de l'invention a pour but de supprimer tous ces inconvénients. La présente invention est un poteau de volleyball constitué d' un montant ayant une section tubulaire standard ou une section formant un rail interne, d'un support coulissant avec le dit montant destiné à régler la hauteur d'un filet, ce dit support coulissant étant muni de moyens pour attacher et /ou tendre le filet et d'un moyen de maintien dudit support à la hauteur voulue par rapport audit montant caractérisé en ce que le support coulissant comporte en partie haute au moins un moyen lui permettant de rouler contre l'extérieur ou contre l'intérieur du dit montant lorsque l'on règle la hauteur du filet même lorsque ce dernier est sous tension. De plus le filet comporte dans sa partie supérieure un câble de tension, le moyen de roulement comporte un axe de rotation étant situé au même niveau que le dit câble de tension. Dans un mode de réalisation optimisé, le moyen permettant au support coulissant de rouler se présente sous la forme d'au moins un roulement à billes ou à galets. Le résultat obtenu avec cette invention est un poteau de volleyball permettant de changer rapidement et facilement de hauteur du filet sans avoir à détendre et retendre le filet. L'invention permet donc le réglage de la hauteur du filet lorsqu'il est tendu. La description qui va suivre est faite à titre d'exemple indicatif et non limitatif au regard des dessins annexés sur lesquels : La figure 1 montre un poteau de volleyball dans un mode de fabrication avec un montant de section tubulaire standard ainsi qu'une partie du filet.The present invention relates to volleyball poles. Most volleyball poles consist of a vertical tubular upright and a sliding support with the said amount where the net is fixed. This said sliding support is intended to adjust the height of the net for the different levels of competition. The regulations concerning the height and the tension of the net are very strict and impose heights above the lateral lines and a height in the center of the ground, moreover there are five official heights for the different levels of competition. When adjusting the height of the net, the existing volleyball poles are tedious to adjust, you must first relax the net then adjust the new height on each side, tighten the net and check the three heights. It usually takes several times to get a net at a height and tension in accordance with the regulations. The object of the invention is to remove all these disadvantages. The present invention is a volleyball post consisting of an upright having a standard tubular section or a section forming an inner rail, a sliding support with said amount intended to adjust the height of a net, said sliding support being provided with means for attaching and / or tensioning the net and means for maintaining said support at the desired height relative to said post, characterized in that the sliding support comprises at the top part at least one means enabling it to roll against the outside or against the inside of said amount when one adjusts the height of the net even when the latter is under tension. In addition the thread has in its upper part a tension cable, the rolling means comprises an axis of rotation being located at the same level as said tension cable. In an optimized embodiment, the means allowing the sliding support to roll is in the form of at least one ball bearing or roller. The result obtained with this invention is a volleyball pole allowing to quickly and easily change the height of the net without having to relax and tighten the net. The invention thus allows the adjustment of the height of the net when it is stretched. The following description is given by way of indicative and nonlimiting example with reference to the accompanying drawings, in which: FIG. 1 shows a volleyball post in a method of manufacture with a standard tubular section upright and a part of the net.
La figure 2 est une vue de dessus agrandie de la figure 1. La figure 3 montre un poteau de volleyball en coupe dans un mode de fabrication avec un montant de section formant un rail interne. (Coupe AA défmie sur la figure 4) La figure 4 est une vue de dessus de la figure 3. Sur la figure 1 on voit le montant (1) de section tubulaire ronde standard en acier ou aluminium par exemple et on voit le support coulissant (2) avec le dit montant (1), ce dit support (2) étant réalisé en acier ou en aluminium par exemple. Ce dit support coulissant (2) comporte les moyens (4) pour attacher et /ou tendre le filet (3) et d'un moyen de maintien (5) à la hauteur -2- voulue avec le dit montant (1). En partie haute du support coulissant (2) on voit un moyen de renvoi (9) permettant aux drisses (10) du filet (3) de s'orienter vers les moyens (4) ces derniers permettant l'attache et/ ou la tension du filet (3) par une crémaillère à manivelle dans ce mode de réalisation. On voit aussi en partie haute le moyen (6) permettant au support coulissant de rouler contre le dit montant (1). Le moyen (6) comporte un axe de rotation (7) solidaire du support coulissant (2). Le moyen (6) permettant au support coulissant de rouler contre le dit montant (1) se situe en dessous de l'axe horizontal (8) ce qui a pour conséquence lorsque le filet (3) est tendu le basculement du support coulissant (2) sur l'axe (7) du moyen (6) engendrant ainsi un frottement au niveau du point (12) entre le montant (1) et le support coulissant (2). Ce frottement néfaste lors du 10 réglage du filet (3) est annulé par un faible effort sur le bas du support coulissant (2) dirigé vers le centre du terrain. Ainsi le moyen (6) peut être positionné en dessous de l'axe horizontal (8) du filet (3) si le support coulissant (2) est suffisamment long pour garantir un fonctionnement aisé. La figure 2 montre en vue de dessus le poteau de volleyball de la figure 1. Pour plus de clarté la figure 2 ne représente pas toutes les pièces. On voit les drisses (10) passant de part et d'autre du 15 montant (1) qui redescendent grâce au moyen de renvoi (9) s'attacher aux moyens (4) d'attache et/ou de tension. On voit le moyen (6) permettant au support coulissant (2) de rouler en appui contre l'extérieur du dit montant (1) cylindrique, ce moyen (6) est dans ce mode de réalisation une roulette ou un roulement à bille ou à galets. La figure 3 montre un poteau de volleyball en coupe dans un mode de fabrication avec un 20 montant de section formant un rail interne. En général ces types de montant sont des profils d'aluminium extrudés. On voit sur cette figure que le montant (1) comporte à l'intérieur le support coulissant (2) muni des moyens (4) d'attache et de tension du filet (3) et du moyen de maintien (5). Dans ce mode de réalisation on voit que l'axe de rotation (7) du moyen (6) permettant au support coulissant de rouler est positionné au même niveau que l'axe horizontal (8) du câble (11) du filet 25 (3). Ce positionnement du dit moyen (6) annule le basculement du support coulissant ce qui facilite son déplacement lors du réglage. Sur la figure 4 toutes les pièces ne sont pas dessinées pour plus de clarté du système. On voit que le moyen (6) permet au support coulissant (2) de rouler contre l'intérieur du dit montant (1). Ce dit moyen (6) étant réalisé avec deux roulettes ou roulements à billes ou à galets dans ce mode 30 de réalisation. Dans les modes de fabrication des figures 1 et 2 le support coulissant peut être réalisé en acier peint ou en aluminium ou tout autre matériau résistant aux efforts.Fig. 2 is an enlarged top view of Fig. 1. Fig. 3 shows a sectional volleyball post in a method of manufacture with a section post forming an internal rail. FIG. 4 is a top view of FIG. 3. FIG. 1 shows the upright (1) of standard round tubular section made of steel or aluminum, for example, and the sliding support is seen. (2) with said amount (1), said support (2) being made of steel or aluminum for example. Said sliding support (2) comprises means (4) for attaching and / or tensioning the net (3) and a holding means (5) at the desired height -2- with said amount (1). In the upper part of the sliding support (2) there is a return means (9) allowing the halyards (10) of the net (3) to orient towards the means (4), the latter allowing the attachment and / or tension of the net (3) by a crank rack in this embodiment. We also see in the upper part the means (6) allowing the sliding support to roll against the said amount (1). The means (6) comprises an axis of rotation (7) integral with the sliding support (2). The means (6) allowing the sliding support to roll against said upright (1) is located below the horizontal axis (8) which has the consequence that when the net (3) is stretched the tilting of the sliding support (2) ) on the axis (7) of the means (6) thus generating a friction at the point (12) between the upright (1) and the sliding support (2). This harmful friction during the adjustment of the thread (3) is canceled by a small effort on the bottom of the sliding support (2) directed towards the center of the ground. Thus the means (6) can be positioned below the horizontal axis (8) of the thread (3) if the sliding support (2) is long enough to ensure easy operation. Figure 2 shows a top view of the volleyball pole of Figure 1. For clarity, Figure 2 does not represent all parts. We see the halyards (10) passing on either side of the upright (1) which descend through the means of reference (9) attach to the means (4) of attachment and / or tension. We see the means (6) allowing the sliding support (2) to roll against the outside of said cylindrical upright (1), this means (6) is in this embodiment a roller or a ball or roller bearing. rollers. Figure 3 shows a sectional volleyball post in a method of manufacture with a cross-section amount forming an inner rail. In general these types of amounts are extruded aluminum profiles. It can be seen in this figure that the upright (1) comprises inside the sliding support (2) provided with means (4) for attaching and tensioning the net (3) and the holding means (5). In this embodiment, it can be seen that the axis of rotation (7) of the means (6) allowing the sliding support to roll is positioned at the same level as the horizontal axis (8) of the cable (11) of the thread (3). ). This positioning of said means (6) cancels the tilting of the sliding support which facilitates its movement during adjustment. In Figure 4 all parts are not drawn for clarity of the system. We see that the means (6) allows the sliding support (2) to roll against the inside of said amount (1). Said means (6) being made with two rollers or ball or roller bearings in this embodiment. In the manufacturing modes of Figures 1 and 2 the sliding support can be made of painted steel or aluminum or other stress-resistant material.
