Description

Planche de loisirs Leisure board
La présente invention concerne un nouvel engin de loisirs.The present invention relates to a new leisure vehicle.
Les sports de loisirs se développent de plus en plus. Les jeunes prisent particulièrement les engins de loisirs permettant un déplacement rapide et dans lesquels le corps est soutenu par une planche. On peut citer en particulier l'essor considérable pris par le surf des neiges. Dans le surf des neiges, la planche glisse sur le support neigeux et la prise de virages procure de fortes sensations parce que le corps se couche au moment du virage pour maintenir l'équilibre. Mais on peut aussi citer le surf aquatique, la planche à voile et la planche à roulettes qui procurent dans une certaine mesure des sensations analogues. On ne connaît actuellement aucun engin qui procure des sensations proches de celles du surf des neiges, mais destiné à la route, c'est-à-dire en fait muni de roue(s) ou roulettes.Recreational sports are developing more and more. Young people particularly appreciate recreational machines allowing rapid movement and in which the body is supported by a board. We can cite in particular the considerable boom taken by snowboarding. In snowboarding, the board slides on the snowy support and taking turns provides strong sensations because the body lies down at the time of the turn to maintain balance. But we can also cite water surfing, windsurfing and skateboarding which to a certain extent provide similar sensations. We currently know of no machine that provides sensations close to those of snowboarding, but intended for the road, that is to say in fact provided with wheel (s) or casters.
On connaît bien la planche à roulettes (skate board), mais le support procuré par les deux paires de roulettes installées sous la face inférieure de la planche est particulièrement stable en raison de l'existence de quatre points de contact espacés longitudinalement et latéralement. En outre la taille des roues ne permet pas d'affronter un sol irrégulier.Skateboards are well known, but the support provided by the two pairs of casters installed under the underside of the board is particularly stable due to the existence of four contact points spaced longitudinally and laterally. In addition, the size of the wheels does not allow it to face uneven ground.
Il serait donc souhaitable de disposer d'une planche permettant le déplacement sur route, le terme de route étant bien évidemment pris au sens large (incluant les trottoirs, les aires de jeu dédiées ou non, etc.) qui permettrait des sensations analogues à celles du surf des neiges.It would therefore be desirable to have a board allowing movement on the road, the term road being obviously taken in the broad sense (including sidewalks, play areas dedicated or not, etc.) which would allow sensations similar to those snowboarding.
En outre, l'engin devrait de préférence être muni d'un système d'entraînement, de telle sorte qu'il ne soit pas nécessaire de poser un pied à terre pour prendre ou conserver de l'élan ou de la vitesse. II devrait également si possible permettre de circuler sur des terrains accidentés, voire même de sauter des obstacles. Après de longues recherches, le demandeur a mis au point un engin de type général planche à roulettes, dans lequel le déplacement de l'engin peut être par exemple obtenu grâce à un des mouvements alternatifs du conducteur s'écartant et se rapprochant de la surface de roulement en gardant les pieds au contact de la planche.In addition, the machine should preferably be equipped with a drive system, so that it is not necessary to put a foot on the ground to gain or maintain momentum or speed. It should also, if possible, make it possible to travel over uneven terrain, or even to jump over obstacles. After lengthy research, the applicant has developed a general skateboard type machine, in which the movement of the machine can for example be obtained by means of one of the driver's reciprocating movements moving away and approaching the surface. rolling, keeping your feet in contact with the board.
C'est pourquoi la présente demande a pour objet une planche de loisirs permettant un déplacement sur route et dans laquelle le conducteur a ses pieds en appui sur ladite planche, caractérisé en ce qu'elle comprend une roue articulée et suspendue par rapport à la planche de telle sorte que l'axe de la roue s'écarte et se rapproche alternativement de la planche sous l'action du poids du corps du conducteur.This is why the present application relates to a leisure board allowing movement on the road and in which the driver has his feet resting on said board, characterized in that it comprises an articulated wheel and suspended relative to the board. in such a way that the axis of the wheel moves away and alternately approaches the board under the action of the weight of the driver's body.
Dans la présente invention et dans ce qui suit, l'on entend parIn the present invention and in what follows, by
"articulée par rapport à la planche de telle sorte que l'axe de la roue s'écarte et se rapproche de la planche", que la roue est capable de se déplacer sensiblement perpendiculairement à la planche grâce à un mécanisme approprié tel que ceux illustrés ci-après."articulated with respect to the board so that the axis of the wheel moves away and approaches the board", that the wheel is able to move substantially perpendicular to the board thanks to an appropriate mechanism such as those illustrated below.
Lorsqu'elle n'est pas chargée la planche est en position haute, ou écartée du sol.When it is not loaded, the board is in the high position, or removed from the ground.
L'articulation peut avantageusement permettre un déplacement de la roue pratiquement perpendiculairement à la surface de la planche. L'on peut faire dans ce cas un parallèle avec le déplacement des roues d'une voiture par rapport à son châssis, le châssis étant l'analogue de la planche de l'invention. Dans un mode de réalisation, la planche peut être munie de bagues dotées notamment de roulements à billes, lesdites bagues servant de guides à des tubes de préférence cylindriques, formant un cadre pour l'axe de la roue. Ces tubes installés perpendiculairement à la planche peuvent ainsi coulisser dans les bagues.The articulation can advantageously allow a movement of the wheel practically perpendicular to the surface of the board. In this case, a parallel can be made with the movement of the wheels of a car with respect to its chassis, the chassis being the analog of the board of the invention. In one embodiment, the board may be provided with rings provided in particular with ball bearings, said rings serving as guides for preferably cylindrical tubes, forming a frame for the axis of the wheel. These tubes installed perpendicular to the board can thus slide in the rings.
En vue de la suspension de la roue articulée par rapport à la planche, le mécanisme de suspension peut être du type à ressort à boudin. Les tubes peuvent alors être installés co-axialement dans des ressorts à boudin, la base d'un tube servant de siège inférieur au ressort correspondant, tandis que le siège supérieur du ressort est installé sur la planche. Pour des questions d'équilibre, il est préférable que ces tubes soient en nombre pair, par exemple au nombre de deux et de préférence au nombre de quatre. Les ressorts à boudin sont avantageusement choisis de manière à permettre la plus grande amplitude possible de déplacement alternatif, tout en évitant toutefois d'aller en butée sous le poids du corps.For the suspension of the articulated wheel relative to the board, the suspension mechanism can be of the coil spring type. The tubes can then be installed co-axially in coil springs, the base of a tube serving as a lower seat for the corresponding spring, while the upper spring seat is installed on the board. For balance reasons, it is preferable that these tubes are in even number, for example two in number and preferably four in number. The coil springs are advantageously chosen so as to allow the greatest possible amplitude of reciprocating movement, while however avoiding going into abutment under the weight of the body.
Dans une telle configuration, les ressorts à boudin sont installés et comprimés entre leur siège supérieur installé sur la planche et leur siège inférieur installé à la base des tubes prévus pour l'installation de l'axe de la roue. Mais un seul tube pourra aussi être suffisant pour servir d'articulation par rapport à la planche et donc un seul ressort sera alors suffisant pour la suspension. En général un tube unique ne sera pas de section circulaire pour ne pas compliquer le guidage de la ou des roues dans la direction du déplacement de la planche. La présente demande a donc aussi pour objet une planche de loisirs ci-dessus, caractérisée en ce qu'elle comporte de 1 à 4 tubes d'articulation par rapport à la planche. Les tubes seront de préférence de section transversale circulaire, mais pourront être par exemple de section ovale ou parallélépipédique comme carrée. Dans une autre configuration, le mécanisme d'articulation et/ou de suspension est du type cantilever. Dans un tel cas, la roue ne se déplace pas perpendiculairement ou sensiblement perpendiculairement par rapport à un châssis comme précédemment, mais selon un arc de cercle dont le centre est l'axe du levier. On a donc un bras articulé et suspendu à un bout sur un axe situé vers une extrémité de la planche, à distance de son milieu, l'autre bout du bras portant l'axe de la roue.In such a configuration, the coil springs are installed and compressed between their upper seat installed on the board and their lower seat installed at the base of the tubes provided for the installation of the wheel axle. But a single tube may also be sufficient to serve as an articulation with respect to the board and therefore a single spring will then be sufficient for the suspension. In general, a single tube will not have a circular section so as not to complicate the guiding of the wheel or wheels in the direction of movement of the board. The present application therefore also relates to a leisure board above, characterized in that it comprises from 1 to 4 articulation tubes with respect to the board. The tubes will preferably be of circular cross section, but may for example be of oval or parallelepipedal section as square. In another configuration, the articulation and / or suspension mechanism is of the cantilever type. In such a case, the wheel does not move perpendicularly or substantially perpendicularly to a frame as before, but in an arc, the center of which is the axis of the lever. There is therefore an articulated arm suspended from one end on an axis located towards one end of the board, at a distance from its center, the other end of the arm carrying the axis of the wheel.
Dans un cas comme dans l'autre, la roue est installée avantageusement vers le milieu de la planche, tant latéralement que longitudinalement. Selon le diamètre de la roue et l'amplitude de son mouvement alternatif, le milieu de la planche pourra comporter un évidement pour permettre à la roue de la traverser en position basse. Dans des conditions préférentielles à la mise en œuvre de l'invention, la roue comprend en outre un mécanisme d'entraînement actionné par le poids du corps.In either case, the wheel is installed advantageously towards the middle of the board, both laterally and longitudinally. Depending on the diameter of the wheel and the amplitude of its reciprocating movement, the middle of the board may include a recess to allow the wheel to cross it in the low position. Under conditions preferential to the implementation of the invention, the wheel further comprises a drive mechanism actuated by the weight of the body.
Ce mécanisme d'entraînement peut être de tout type connu dans la mécanique. Il comprend de préférence un pignon à roue libre, comme on le trouve sur les roues arrières des bicyclettes. En vue de réaliser l'entraînement, on peut alors prévoir une chaîne de vélo venant actionner le pignon, soit lors de la descente de la planche vers le sol, soit lors de la remontée de celle-ci.This drive mechanism can be of any type known in mechanics. It preferably includes a freewheel pinion, as found on the rear wheels of bicycles. In order to carry out the drive, it is then possible to provide a bicycle chain which actuates the pinion, either when the board descends towards the ground, or when it rises.
On peut à cette fin par exemple prévoir une chaîne dont les deux extrémités sont fixées indépendamment l'une de l'autre au châssis, l'une directement, l'autre par l'intermédiaire d'un ressort à boudin. Ainsi, par exemple, lorsque sous le poids du corps la planche s'abaisse, elle se rapproche de l'axe de la roue et du pignon, et le ressort à boudin raccourcit la longueur de la chaîne en bénéficiant de la roue libre. Lorsque la planche remonte, le pignon est alors en prise et la chaîne actionne la roue, tandis que le ressort à boudin se tend. L'entraînement peut donc se faire lors de la remontée de la planche ou lors de la descente de la planche sous le poids du corps du conducteur.For this purpose, it is possible, for example, to provide a chain, the two ends of which are fixed independently of one another to the chassis, one directly, the other by means of a coil spring. Thus, for example, when under the weight of the body the board lowers, it approaches the axis of the wheel and the sprocket, and the coil spring shortens the length of the chain by taking advantage of the free wheel. When the board rises, the pinion is then engaged and the chain actuates the wheel, while the coil spring tightens. The training can therefore be done when raising the board or when lowering the board under the weight of the driver's body.
On peut aussi prévoir par exemple une crémaillère fixée sous la planche, venant en prise sur le pignon précité. Afin de faciliter le démarrage, l'arrière de la planche peut être muni d'un dispositif pour stabiliser celle-ci à l'arrêt.One can also provide for example a rack fixed under the board, engaging the aforementioned pinion. To facilitate starting, the back of the board can be fitted with a device to stabilize it when stopped.
C'est pourquoi la présente invention a également pour objet une planche ci-dessus, caractérisée en ce qu'elle comporte par exemple deux bossages ou roulettes sous l'une de ses extrémités, de telle sorte que la planche à l'arrêt est supportée en trois points donc de manière stable par ces deux bossages ou roulettes et par la roue (ou les roulettes centrales).This is why the present invention also relates to a board above, characterized in that it comprises for example two bosses or rollers under one of its ends, so that the stationary board is supported in three points therefore stably by these two bosses or rollers and by the wheel (or the central rollers).
Ainsi, lors du démarrage, on peut placer un de ses pieds à l'arrière de la planche à proximité des bossages ou roulettes, et l'autre pied vers l'avant de la planche. Un appui sur le pied avant permet de mettre en prise l'entraînement de la roue, et la diminution de la pression sur l'avant de la planche fait avancer l'engin. On peut ainsi progressivement prendre de la vitesse pour acquérir de l'équilibre et continuer le déplacement avec la planche parallèle au sol, en rapprochant le pied arrière du centre de la planche, l'ensemble du corps permettant par une série de fléchissements et d'extensions des jambes de maintenir la vitesse.Thus, during startup, one can place one of its feet at the rear of the board near the bosses or rollers, and the other foot towards the front of the board. Pressing the front foot engages the wheel drive, and the decrease in pressure on the front of the board advances the machine. We can gradually gain speed to gain balance and continue moving with the board. parallel to the ground, bringing the rear foot closer to the center of the board, the whole body making it possible to maintain speed by a series of flexions and leg extensions.
La roue est de préférence unique. Son diamètre peut aller de préférence de 10 à 60 cm, notamment de 15 à 50 cm, particulièrement de 30 à 50 cm. On peut aussi remplacer la roue unique par une série de 2 ou plusieurs, par exemple 4 roulettes. Dans ce cas, un seul tube sera alors suffisant pour servir d'articulation par rapport à la planche et donc un seul ressort sera alors suffisant pour la suspension. L'invention sera mieux comprise si l'on se réfère aux dessins annexés sur lesquels :The wheel is preferably unique. Its diameter can preferably range from 10 to 60 cm, in particular from 15 to 50 cm, particularly from 30 to 50 cm. You can also replace the single wheel with a series of 2 or more, for example 4 casters. In this case, a single tube will then be sufficient to serve as an articulation with respect to the board and therefore a single spring will then be sufficient for the suspension. The invention will be better understood if reference is made to the appended drawings in which:
