Abstract

The net is adjusted by a telescopic tube (2,4) whose upper tube (2) is closed at the top. The lower tube (4) has a nut (5) fixed inside it and a screw (3), fixed to the top of the upper tube, is screwed into this. The lower tube has a knurled wheel (6) fixed to its base and this is joined to a stud (7). This is held in a snap hook (9) which is fixed to the ground (14) and can turn in this. An adjustable strap passes through a loop (1), fixed to the top of the upper tube, and round the net.

Description

DESCRIPTION
La présente invention, concerne le réglage en hauteur et le maintien des filets de tennis, au point central du filet.
DESCRIPTION
The present invention relates to the height adjustment and the maintenance of tennis nets, at the central point of the net.

Ils sont généralement, réglés et maintenus avec une sangle qui chevauche le cable du filet. Cette sangle, qui est fixée au sol, est munie d'une boucle, ou d'une bande " Velcro ", pour le réglage. Il s'avère qu'à l'usage, et pour diverses raisons, la hauteur du filet varie, pour ce qui est des sangles à boucle, ou les extrémitées se décrochent, pour ce qui est des bandes " Velcro". They are generally adjusted and maintained with a strap which overlaps the net cable. This strap, which is fixed to the ground, is provided with a buckle, or a "Velcro" band, for adjustment. It turns out that in use, and for various reasons, the height of the net varies, as far as the buckle straps are concerned, or the ends come loose, as regards the "Velcro" bands.

L'appareil, figure 1 de la planche unique 1/1, a pour but de simplifier le réglage, et d'assurer un maintien efficace du filet à la hauteur réglementaire, qui est de 91,5 centimètres, au milieu du filet. The device, Figure 1 of the single 1/1 board, aims to simplify the adjustment, and ensure effective maintenance of the net at the regulatory height, which is 91.5 centimeters, in the middle of the net.

Il comporte 3 parties essentielles 1 : La boucle ( 1 ), est rendue solidaire du tube supérieur (2). Le sommet du tube est fermé. La vis de réglage (3), est centrée et fixée sur la fermeture du tube. Ces 3 piéces forment la partie supérieure de l'appareil. La boucle (1), permet le passage de la sangle en double, qui maintient le haut du filet. It has 3 essential parts 1: The loop (1) is made integral with the upper tube (2). The top of the tube is closed. The adjusting screw (3) is centered and fixed on the tube closure. These 3 parts form the upper part of the device. The loop (1) allows the passage of the double strap, which holds the top of the net.

2 : L'écrou (S), solidaire du tube inférieur (4), est positionné à l'intérieur, et environ au milieu du tube. La molette (6), permet de visser ou dévisser, le tube inférieur, dans, et vers le haut du tube supérieur (2), pour monter ou descendre le filet, ( flèches A et B ). L'ergot (7), qui est étanche et fixé au centre de la molette (6), tourne avec le tube (4). 2: The nut (S), integral with the lower tube (4), is positioned inside, and approximately in the middle of the tube. The wheel (6), allows to screw or unscrew, the lower tube, in and up the upper tube (2), to raise or lower the net, (arrows A and B). The lug (7), which is sealed and fixed in the center of the wheel (6), rotates with the tube (4).

3 : Le mousqueton (8), comporte une partie plate en haut, avec un trou qui permet à l'ergot (7) de tourner, quand le vissage et le dévissage sont effectués. Le mousqueton, avec sa partie ouvrable, permet l'arrimage de l'appareil au crochet (9), qui est fixé au sol (14). 3: The carabiner (8) has a flat part at the top, with a hole which allows the lug (7) to turn, when the screwing and unscrewing are carried out. The carabiner, with its opening part, allows the attachment of the device to the hook (9), which is fixed to the ground (14).

Mise en place et réglage de l'appareil, avec la course de réglage partagée 1) Si la hauteur totale de l'appareil, ( rien n'est limitatif ), du sol au sommet de la boucle (1 ), mesure 15 centimètres, la distance de la boucle (1 ), au haut du filet devra mesurer environ 76 centimètres, et la sangle 160 centimètres environ. La sangle passe dans la boucle (1 ), dans la maille du filet située à 76 centimètres du haut du filet environ, elle passe sur le haut de la bande, et les deux extrémitées de la sangle sont assemblées par des vis ou des rivets. Installation and adjustment of the device, with the shared adjustment stroke 1) If the total height of the device, (nothing is limiting), from the ground to the top of the loop (1), measures 15 centimeters, the distance from the loop (1) at the top of the net should be around 76 cm, and the strap around 160 cm. The strap passes through the loop (1), in the mesh of the net located about 76 centimeters from the top of the net, it passes over the top of the band, and the two ends of the strap are assembled by screws or rivets.

(16). Plusieurs trous peuvent être prévus pour un réglage plus facile. (16). Several holes can be provided for easier adjustment.

2) Dans la figure (3), le crochet (17), maintient la pige (18) contre le filet.2) In figure (3), the hook (17) holds the rod (18) against the net.

La pige, ( qui est à la hauteur voulue ), ne touche pas le sol. Il faut visser le tube inférieur (4) pour descendre le filet, et amener le bas de la pige contre le sol.The rod (which is at the desired height) does not touch the ground. You have to screw the lower tube (4) to lower the net, and bring the bottom of the rod against the ground.

Cet appareil peut être réalisé avec un métal quelconque, ( en fonderie, en mécano-soudure ou autres procédés ), en plastique, ( par moulage, extrusion ou autres procédés, pouvant as s urer une fabrication facile et suffisamment solide. L'appareil décrit est métallique, ( fer ou autres ), et pour éviter un mauvais fonctionnement et une oxydation prématurée de la vis (3) et de l'écrou (5), le tube inférieur (4) est rempli d'huile. Un trou peut être prévu dans l'écrou, pour faciliter le passage de l'huile, au vissage et au dévissage. This device can be made with any metal (foundry, mechanical welding or other processes), plastic, (by molding, extrusion or other processes, which can be sure easy and sufficiently solid manufacturing. The device described is metallic, (iron or other), and to avoid malfunction and premature oxidation of the screw (3) and the nut (5), the lower tube (4) is filled with oil. provided in the nut, to facilitate the passage of oil, screwing and unscrewing.

La figure ClaL représente l'appareil vu d'en haut. La figure 2, représente l'appareil (13), arrimé au sol (14), et la double sangle, qui passe dans la boucle (1 ), contre le filet (12), et au-dessus de la bande (10), les deux extrémitées étant assemblées avec les vis ou les rivets (16). The ClaL figure represents the device seen from above. Figure 2 shows the device (13), stowed on the ground (14), and the double strap, which passes through the loop (1), against the net (12), and above the band (10) , the two ends being assembled with the screws or the rivets (16).

La figure (3), représente une pige (18), avec un crochet (17) placé sur la bande du filet, pour en faciliter le réglage.  Figure (3) shows a rod (18), with a hook (17) placed on the strip of the net, to facilitate adjustment.
