ENSEMBLE DE SYSTEMES D'AMELIORATIONS POUR TRAMPOLINE AASSEMBLY OF IMPROVEMENT SYSTEMS FOR TRAMPOLIN A
USAGE SPORTIFSPORTS USE
La présente invention concerne des systèmes d'amélioration pour trampoline à usage sportif. Les trampolines actuellement sur le marché et notamment les trampolines de compétition mesurent environ 5 m x 3 m et sont pliants pour faciliter le rangement. Ils présentent plusieurs points dangereux: danger lors de chute des trampolinistes sur l'un des petits côtés du cadre et danger lors du pliage. D'autre part. les réglages sont difficiles lors de l'installation (au niveau de la planéité) et les chaines retenant les pieds se détendent lors de l'utilisation. Les parties métalliques sont constituées de pièces de grande dimension difficilement transportables. Leur conception ne pennet pas The present invention relates to improvement systems for a trampoline for sports use. The trampolines currently on the market and in particular the competition trampolines measure approximately 5 m x 3 m and are foldable for easy storage. They present several dangerous points: danger when the trampolinists fall on one of the short sides of the frame and danger during folding. On the other hand. adjustments are difficult during installation (in terms of flatness) and the chains holding the feet relax during use. The metal parts are made up of large parts that are difficult to transport. Their design does not allow
l'adaptation de tension de la toile en fonction des utilisateurs. adaptation of fabric tension according to users.
L'objet de l'invention a pour but de supprimer ces inconvénients. The object of the invention is to eliminate these drawbacks.
Le trampoline décrit ci-dessous est fabriqué à partir de pièces métalliques de petites dimensions (environ la moitié par rapport aux fabrications traditionnelles) facilitant le transport et la livraison de l'appareil démonté. Le pliage se fait à l'aide de 2 chariots The trampoline described below is made from small metal parts (about half compared to traditional manufacturing) facilitating the transport and delivery of the disassembled device. Folding is done using 2 trolleys
munis de pédale qui suppriment tout risque de coincement pour l'utilisateur. fitted with a pedal which eliminates any risk of jamming for the user.
Tous les tirants de maintien en position travail sont rigides et très facilement réglables afin de positionner le trampoline de façon parfaitement horizontale et à la hauteur voulue. Le réglage en élasticité permet d'ajuster le trampoline en fonction du poids des trampolinistes et des exercices travaillés. Ce réglage se fait en faisant varier l'écartement des pieds. Sachant que les pieds maintiennent d'une part la stabilité du cadre et permettent le respect de ses dimensions pour environ 80%, si les parties supérieures des pieds emboîtées sur les cadres sont plus ou moins écartées, les deux grands côtés du cadre vont s'éloigner ou se rapprocher, permettant une tension plus ou moins forte des ressorts et de la toile. La sécurité lors de chutes sur les petits côtés du cadre a été renforcée par un système permettant à ceux-ci de s'abaisser progressivement, en cas de choc ou de chute sur le cadre. Le principe de déclenchement All the tie rods for holding in the working position are rigid and very easily adjustable in order to position the trampoline perfectly horizontal and at the desired height. The elasticity adjustment makes it possible to adjust the trampoline according to the weight of the trampolinists and the exercises worked. This adjustment is made by varying the spacing of the feet. Knowing that the feet maintain on the one hand the stability of the frame and allow the respect of its dimensions for about 80%, if the upper parts of the feet fitted on the frames are more or less separated, the two long sides of the frame will move away or get closer, allowing a more or less strong tension of the springs and the fabric. Safety during falls on the short sides of the frame has been reinforced by a system allowing them to lower gradually, in the event of an impact or fall on the frame. The trigger principle
du système de sécurité est identique à celui des portes de sécurité. security system is identical to that of security doors.
La figure I représente un trampoline en position de fonctionnement, sans la protection qui recouvre la totalité des ressorts (1), sans les tapis de sécurité posés aux extrémités sur les banquettes (2). Ces dernières sont représentées en pointillés afin de mieux visualiser les parties mécaniques. Les banquettes (2) sont réalisées en matière Figure I shows a trampoline in the operating position, without the protection that covers all of the springs (1), without the safety mats placed at the ends on the benches (2). These are shown in dotted lines to better visualize the mechanical parts. The benches (2) are made of

question de sécurité.Security Question.
L'écrou (20) est soudé à la tige filetée (18). L'écrou (21) est soudé ou solidaire du tube The nut (20) is welded to the threaded rod (18). The nut (21) is welded or integral with the tube
cylindrique du pied (10).cylindrical of the foot (10).
Etant donné que les ressorts donnent une forte pression sur le cadre, l'écrou (20) soudé à la tige filetée (18) se trouve en appui sur le tube cylindrique (12) fermé en son Since the springs give a strong pressure on the frame, the nut (20) welded to the threaded rod (18) is supported on the cylindrical tube (12) closed in its
extrémité au point (22).end at point (22).
Cette partie (22) comporte un trou correspondant au diamètre de la tige filetée qui elle This part (22) has a hole corresponding to the diameter of the threaded rod which it
même dépasse et reçoit la manivelle amovible (1 9). even exceeds and receives the removable crank (1 9).
La manipulation de la manivelle a pour effet d'éloigner ou de rapprocher l'écrou (21) solidaire du pied (10) de la partie de frottement (22) ce qui engendre des variations The manipulation of the crank has the effect of moving away or closer to the nut (21) integral with the foot (10) of the friction part (22) which generates variations
dimcnsionnelles des extrémités du pied, donc du cadre, et ce aux 4 points de pliage (12). dimensions of the ends of the foot, therefore of the frame, and this at the 4 folding points (12).
La figure 5 montre les 2 tirants vus de côté. Le tirant (14) relie la partie linéaire (7) au pied ( 10) et montre schématiquement l'ergot de forme cylindrique (24) (grossi pour une meilleure compréhension) de l'extrémité du tirant (14) emboîté et verrouillé par les Figure 5 shows the 2 tie rods seen from the side. The tie rod (14) connects the linear part (7) to the foot (10) and schematically shows the cylindrical lug (24) (magnified for a better understanding) of the end of the tie rod (14) fitted and locked by the
pièces (23) et (25).parts (23) and (25).
Pour emboîter l'ergot (24) du tirant (14), il suffit de le présenter sur les pièces (25) et (23). L'ergot (24) du tirant (14) se positionne au fond de l'encoche de la pièce (23) en faisant basculer la pièce (25) qui bascule à nouveau par son poids., dans l'autre sens et To fit the lug (24) of the tie rod (14), it suffices to present it on the parts (25) and (23). The lug (24) of the tie rod (14) is positioned at the bottom of the notch of the part (23) by tilting the part (25) which rocks again by its weight., In the other direction and
verrouille l'ergot (24) du tirant (14). locks the lug (24) of the tie rod (14).
Ces pièces (25) et (23). de par leur tonne bien calculée, auront pour effet de rattraper tous les jeux mécaniques et de supprimer tout risque de mauvaise manipulation inopinée These parts (25) and (23). due to their well calculated tonne, will have the effect of making up for all mechanical play and eliminating any risk of unexpected improper handling
de déverrouillage du tirant (14).for unlocking the tie rod (14).
Pour le pliage, seule la mise en place de 2 chariots, la manoeuvre des 2 pédales et la bascule manuelle des 2 pièces (25) faite simultanément par 2 personnes peut For folding, only the installation of 2 trolleys, the operation of the 2 pedals and the manual rocking of the 2 parts (25) done simultaneously by 2 people can
déverrouiller les tirants (14).unlock the tie rods (14).
Les variations en longueur des 4 tirants (14) permettent de positionner le trampoline à la hauteur voulue. La figure 5 montre aussi le tirant (13) reliant les parties coudées (4) du cadre au pied The variations in length of the 4 tie rods (14) allow the trampoline to be positioned at the desired height. Figure 5 also shows the tie rod (13) connecting the bent parts (4) of the frame to the foot

La coulisse (26) du tirant (13) est munie en sa partie haute d'une pièce (27) recevant le The slide (26) of the tie rod (13) is provided in its upper part with a part (27) receiving the
doigt de crantage (28) et, en sa partie basse, d' un écrou soudé (29). locking finger (28) and, in its lower part, a welded nut (29).
La vis (30) est soudée sur la pièce (31) qui s'emboîte sur la pièce réceptrice soudée sur The screw (30) is welded to the part (31) which fits onto the receiving part welded to
le pied (10) pour déboîtage et pliage. the foot (10) for disengagement and folding.
En vissant ou dévissant la coulisse (26) on augmente ou on diminue la longueur du tirant (13) ce qui a pour effet de placer la partie (8) de façon parfaitement horizontale By screwing or unscrewing the slide (26) we increase or decrease the length of the tie rod (13) which has the effect of placing the part (8) perfectly horizontal
dans l'alignement des parties linéaires (7). in alignment with the linear parts (7).
Cette vue représente également le svstème de décrantage et d'amortissement lors d'une This view also represents the system of stripping and damping during a
chute sur le petit côté du châssis (4). fall on the short side of the chassis (4).
Le doigt de crantage (28) est prolongé par des barres pivotants autour des axes (33) reliés entre eux pour former un seul axe. La barre (32) relie également les deux barres support des doigts de crantage (28) pour former un ensemble afin que, lorsqu'un trampoliniste tombe sur un côté de la barre (32), les 2 doigts de crantage (28) se décrantent en même temps, telles que les barres de torsion d'un véhicule reliant les 2 The locking finger (28) is extended by pivoting bars around the axes (33) interconnected to form a single axis. The bar (32) also connects the two support bars of the locking fingers (28) to form an assembly so that, when a trampolinist falls on one side of the bar (32), the 2 locking fingers (28) decrement. at the same time, such as the torsion bars of a vehicle connecting the 2
roues arrimères ou avant.stowed or front wheels.
La protection et le tapis sont représentés en pointillés bien qu'utiliseés dans tous lcs cas. The protection and the carpet are shown in dotted lines although they are used in all cases.
La chute aura pour effet d'abaisser la barre (32) ce qui dégage les doigts de crantage (28) des pièces (27) et de ce fait. les coulisses (26) viendront en appui sur les ressorts (34) (ou tout autre moyen d'amortissement tel que vérin. plus approprié puisque n'ayant pas d'effet de retour brutal). Les parties (4) du châssis s'abaisseront suivant le pointillé The fall will lower the bar (32) which releases the locking fingers (28) from the parts (27) and thereby. the slides (26) will come to bear on the springs (34) (or any other damping means such as a jack. more suitable since having no sudden return effect). The parts (4) of the chassis will lower according to the dotted line
et amortiront le choc.and absorb the shock.
Le retour en position verrouillée est automatique, donc ce svstème d'amortissement ne Returning to the locked position is automatic, so this damping system does not
fonctionne qu'en cas de chute sur la barre (32). works only if the bar (32) falls.
Ce même principe peut être appliqué sur le trampoline encastré en fosse. This same principle can be applied to the trampoline built into a pit.
