Abstract

The invention concerns a seesaw with a substantially elliptical support surface, in point contact with the ground, capable of rocking longitudinally or laterally and in rotation. An offset position of children at the ends transforms the rocking into rotation or inversely, rocking maintains or accelerates rotation. The position of the children controls the type and direction of the rocking rotation shifts.

Description

Bascule tourniquet Turnstile
L'invention concerne la réalisation d'un jouet, de plein air ou de collectivité ou d'intérieur.The invention relates to the production of a toy, outdoor or community or indoor.
On connaît les différents modes de réalisation d'une bascule et en particulier la réalisation qui est schématisée figure 1 . La surface d'appui sur le sol est sensiblement un cylindre elliptique réglé, chaque enfant à une extrémité fait basculer le jeu en se balançant d'avant en arrière.We know the different embodiments of a scale and in particular the embodiment which is shown diagrammatically in FIG. 1. The support surface on the ground is essentially an elliptical cylinder adjusted, each child at one end swings the game by swinging back and forth.
Le basculement a lieu dans un plan vertical invariant, l'amplitude de l'oscillation est limitée.The tilting takes place in an invariant vertical plane, the amplitude of the oscillation is limited.
Un tel jeu est destiné à des enfants de premier âge, rapidement les enfants se lassent d'un tel jeu.Such a game is intended for young children, quickly children get tired of such a game.
On observe également des bascules à pallier, tels ceux des jardins publics, utilisés par des enfants plus âgés jusqu'à environ 10 ans, avec comme attrait supplémentaire la hauteur du balancement et le choc de la butée.We also observe flip-flops to overcome, such as those in public gardens, used by older children up to about 10 years, with the additional attraction of the height of the swing and the shock of the stop.
On observe également l'attrait des tourniquets, lié à la vitesse et au vertige.We also observe the attraction of turnstiles, linked to speed and vertigo.
L'invention vise à donner à une bascule d'intérieur de collectivité ou de jardin un attrait nouveau lié à une cinématique imprévisible bien que contrôlable, et à intégrer à cette bascule l'attrait du tourniquet.The invention aims to give an indoor community or garden scale a new attraction linked to an unpredictable although controllable kinematics, and to integrate into this scale the attraction of the turnstile.
Elle vise également à compenser par le nouvel attrait les limites éventuellement liées à une dimension restreinte de la bascule : l'amplitude et la vitesse réduites. Elle vise également à développer le sens de l'équilibre et des transferts de poids.It also aims to compensate by the new attraction the limits possibly linked to a restricted dimension of the rocker: the reduced amplitude and speed. It also aims to develop a sense of balance and weight transfers.
Selon l'invention qui est une variante de la bascule de la figure 1 , prévue pour un ou deux enfants aux extrémités, un mouvement de balancement d'avant en arrière induit par les enfants peut provoquer alternativement un pivotement de la bascule autour de son point de contact au sol dans un sens horaire, un basculement traditionnel dans le plan vertical sans pivotement ou bien un pivotement dans un sens antihoraire.According to the invention which is a variant of the rocker of Figure 1, intended for one or two children at the ends, a rocking movement back and forth induced by children can alternately cause the rocker to pivot around its point contact with the ground in a clockwise direction, a traditional tilting in the vertical plane without pivoting or else a pivoting in a counterclockwise direction.
Un pivotement induit par les enfants peut provoquer la mise en oscillation de la bascule d'avant en arrière ou bien latéralement, sur une amplitude importante.A child-induced pivoting can cause the rocker to swing back and forth or laterally over a large amplitude.
Selon l'invention, les oscillations et les pivotements de la bascule sont couplées de manière contrôlable par les enfants, en fonction de leur position ou de leur inclinaison sur la bascule.According to the invention, the oscillations and swivels of the scale are controllably coupled by children, depending on their position or their inclination on the scale.
Au même titre que par inclinaisons successives, un enfant amplifie le balancement d'une balançoire, les deux enfants contrôlent les amplitudes de balancement et le couplage de l'énergie cinétique en pivotement.Just as by successive inclinations, a child amplifies the swing of a swing, the two children control the swing amplitudes and the coupling of kinetic energy in pivoting.
La possibilité de transférer un mouvement d'oscillation en pivotement ou de réaliser l'opération inverse est peu connue.Little is known about the possibility of transferring an oscillating swing movement or performing the reverse operation.
Dans le brevet FR9615628 du 19 12 96 délivré au même auteur, il est décrit le principe de réalisation d'un objet ludique dont le comportement cinématique correspond à un des comportements de cette nouvelle bascule. il est montré qu'un objet dont la forme extérieure est parfaitement elliptique, mais dont la répartition de masse interne présente un déport de l'axe principal d'inertie de 5° par rapport à l'axe principal de la forme extérieure convertit un pivotement en oscillation puis l'oscillation en pivotement en sens inverse.In patent FR9615628 of 19 12 96 issued to the same author, the principle of making a playful object is described, the kinematic behavior of which corresponds to one of the behaviors of this new rocker. it is shown that an object whose external shape is perfectly elliptical, but whose internal mass distribution has an offset of the main axis of inertia of 5 ° relative to the main axis of the external shape converts a pivoting in oscillation then the oscillation in pivoting in opposite direction.
Sans rentrer dans le détail de la cinématique par ailleurs décrit dans le numéro de janvier 99 de la revue de vulgarisation française 'Pour La Science' il apparaît que la répartition des masses du mobile préside son comportement.Without going into the details of the kinematics otherwise described in the January 99 issue of the popular French magazine 'Pour La Science', it appears that the distribution of the masses of the mobile presides over its behavior.
Ainsi l'invention réalise une bascule dont la forme de l'appui au sol est sensiblement ou parfaitement elliptique.Thus the invention achieves a rocker whose shape of the support on the ground is substantially or perfectly elliptical.
Le contact avec le sol est ponctuel, la surface d'appui étant convexe.The contact with the ground is punctual, the support surface being convex.
La surface d'appui elliptique est définie par des axes, et des rayons (demi axe ) , R 1 , R2, R3.The elliptical bearing surface is defined by axes, and radii (half axis), R 1, R2, R3.
Pour des enfants entre 4 et 10 ans, une surface d'appui dont les rayons sont sensiblement et respectivement R3 = 0.3 m, R2 = 0.5 m, R 1 = 1 .5 m convient.For children between 4 and 10 years old, a support surface whose radii are appreciably and respectively R3 = 0.3 m, R2 = 0.5 m, R 1 = 1.5 m is suitable.
De façon générale, il est nécessaire que R3 < R2 < R 1.Generally, it is necessary that R3 <R2 <R 1.
La surface d'appui au sol ne détermine pas nécessairement la forme générale de la bascule, ni ses longueur largeur et hauteur.The bearing surface on the ground does not necessarily determine the general shape of the scale, nor its length, width and height.
La surface d'appui de forme sensiblement elliptique doit seulement être suffisamment étendue pour assurer l'appui même en cas d'oscillation de forte amplitude.The substantially elliptical bearing surface only needs to be large enough to provide support even in the event of a large amplitude oscillation.
La figure 3 donne un exemple de principe de réalisation (non représentatif des formes réalisables) , avec la surface d'appui 1 , une barre de prise en main 2, une barre fixe un siège 4, cette barre est liée rigidement par une douille 4 à la barre support principale.FIG. 3 gives an example of an embodiment principle (not representative of the achievable shapes), with the support surface 1, a grip bar 2, a bar fixed a seat 4, this bar is rigidly connected by a socket 4 to the main support bar.
Selon un premier principe le plus simple, le siège 4 a une largeur surdimensionnée, les enfants ont la possibilité de se déplacer latéralement dessus.According to a simplest first principle, the seat 4 has an oversized width, children have the possibility of moving laterally on it.
Les enfants ont également la possibilité de prendre appuis sur le sol pour initier un balancement ou un pivotement. Selon le principe particulier de l'invention, le déport latéral des enfants couple les oscillations et les pivotements.Children also have the possibility of taking support on the ground to initiate a swing or pivot. According to the particular principle of the invention, the lateral offset of children couples the oscillations and the pivotings.
Un balancement vertical est immédiatement converti en pivotement dans la direction dans la quelle les enfants pèsent, de même, un pivotement est converti en balancement vertical dés que les enfants pèsent chacun sur leur coté droit ou bien leur coté gauche.A vertical swing is immediately converted into a pivot in the direction in which the children weigh, similarly, a pivot is converted into a vertical swing as soon as the children each weigh on their right side or their left side.
Le jeu consiste alors à faire varier le pivotement et les balancements de la bascule tout en entretenant ces derniers, à accélérer fortement le pivotement en forçant un balancement vertical, etc ...The game then consists in varying the pivoting and the rocking of the rocker while maintaining the latter, in strongly accelerating the pivoting by forcing a vertical rocking, etc ...
Selon un second principe la douille 3 figure 3 est un palier en libre pivotement, et la largeur du siège 4 est ajustée à la taille de l'enfant.According to a second principle, the socket 3 in FIG. 3 is a bearing in free pivoting, and the width of the seat 4 is adjusted to the size of the child.
L'enfant commande alors son déport latéral en agissant par réaction sur la barre 1 .The child then controls his lateral offset by acting by reaction on the bar 1.
Les actions et réactions de la bascule sont alors dépendantes de l'amplitude et de la direction du déport latéral de chaque enfant.The actions and reactions of the rocker are then dependent on the amplitude and direction of the lateral offset of each child.
Naturellement les enfants sont incités à se déporter soit sur leur droite soit sur leur gauche, en conjonction. Sinon, la bascule s'incline latéralement ce qui n'est pas confortable.Naturally children are encouraged to move either to their right or to their left, in conjunction. Otherwise, the rocker tilts laterally which is not comfortable.
Selon un troisième mode de réalisation figure 4 la dite douille est un pallier solidaire d'une poulie qui relie par une courroie par exemple crantée 1 les angles des deux dits sièges, afin de garantir l'équilibre statique de la bascule, quelle que soit l'amplitude du déport latéral des enfants. Les deux déports sont alors conjugués symétriquement.According to a third embodiment in FIG. 4, the said socket is a bearing secured to a pulley which connects the angles of the two said seats by a belt, for example notched 1, in order to guarantee the static balance of the rocker, whatever the amplitude of the lateral offset of children. The two offsets are then symmetrically conjugate.
Tout type de liaison angulaire entre les dits sièges convient à la réalisation de l'invention, dés lors qu'il conserve approximativement centrée la position du centre de gravité de la bascule chargée des enfants.Any type of angular connection between said seats is suitable for carrying out the invention, as long as it retains approximately centered the position of the center of gravity of the rocker loaded with children.
Tout design valorisera l'invention, au niveau décoratif. Le design sera également porteur d'un thème qui induira naturellement le jeu, tel que la moto, le canot, la gondole, le rodéo etc.Any design will enhance the invention, at a decorative level. The design will also carry a theme that will naturally induce the game, such as the motorcycle, the canoe, the gondola, the rodeo etc.
Dés lors son contenu didactique ou d'imitation contribuera à valoriser l'apprentissage de l'équilibre interactif que propose ce jeu.From then on, its didactic or imitation content will contribute to enhancing the learning of the interactive balance that this game offers.
C'est un jeu qui développe le sens de l'équilibre, et qui peut préparer à l'apprentissage de la bicyclette, et à tous les sports d'équilibre.It is a game that develops the sense of balance, and that can prepare for learning to ride a bicycle, and for all balance sports.
Dans une dernière réalisation de la bascule selon l'invention, les enfants gardent les pied à l'intérieur de la coque elliptique, en appui sur des marche pied 1 figure 5 assis sur des sièges 2 figure 5, en tirant sur une main courante réalisée par une corde 3 figure 5, celle-ci leur permet de donner des impulsions de balancement intenses.In a last embodiment of the rocker according to the invention, the children keep their feet inside the elliptical shell, resting on steps 1 figure 5 seated on seats 2 figure 5, pulling on a handrail made by a rope 3 in figure 5, this allows them to give intense rocking pulses.
Ainsi, le contact permanent avec le sol reste ponctuel, et le jeu est une recherche exclusive de l'équilibre et de couplage dynamique.Thus, the permanent contact with the ground remains punctual, and the game is an exclusive search for balance and dynamic coupling.
Bien entendu les enfants occupent deux positions opposées, et à chaque changement de position au cours du jeux, ils sont contraints de changer simultanément, pour ne pas risquer de pencher latéralement. Of course children occupy two opposite positions, and each time they change position during play, they are forced to change simultaneously, so as not to risk leaning sideways.
