- This cam is intended to reduce the amplitude of tilting of the side members (1) between two extreme positions, namely a first position in which the anterior and posterior cams are vertical and bear on the ground, so that the whole of the rocker is blocked and can no longer tilt, and a fully retracted position inside the side member, allowing maximum tilting.

Description
L'invention concerne une bascule, plus particulièrement destinée aux jouets. Elle concerne notamment une bascule destinée à s'adapter à un élément porteur, tel que par exemple un camion, un cheval etc... sur lequel est susceptible de s'asseoir un enfant.The invention relates to a scale, more particularly intended for toys. It relates in particular to a scale intended to adapt to a load-bearing element, such as for example a truck, a horse, etc., on which a child is likely to sit.
A ce jour, de tels jouets à bascule ne comportent généralement pas de dispositif de réglage d'amplitude. De fait, ces jouets à bascule peuvent s'avérer relativement dangereux pour les enfants, dans la mesure où lorsque l'amplitude de basculement devient trop élévée, l'instabilité du jouet, quelquefois recherchée augmente le risque de chute du jouet, et donc de l'enfant.To date, such rocking toys generally do not include an amplitude adjustment device. In fact, these rocking toys can be relatively dangerous for children, since when the tilting amplitude becomes too high, the instability of the toy, sometimes sought increases the risk of falling of the toy, and therefore of the child.
Afin de pallier un tel inconvénient, on a alors proposé des jouets à bascule comportant une butée fixe, solidarisée à la bascule soit à l'avant soit à l'arrière, limitant alors l'amplitude selon une valeur déterminée par le constructeur.In order to overcome such a drawback, rocking toys were then proposed comprising a fixed stop, secured to the rocker either at the front or at the rear, then limiting the amplitude according to a value determined by the manufacturer.
Cette butée fixe est soit encliquetable sur le bâti de la bascule, soit fixable sur celle-ci par tout autre moyen de fixation, ou encore peut être issue du moulage. Elle présente l'inconvénient de limiter à une valeur bien définie l'amplitude de basculement, sans proposer de valeurs intermédiaires, adaptable par exemple en fonction des progrès de l'équilibre de l'enfant.This fixed stop is either snap-on on the frame of the rocker, or fixable on the latter by any other fixing means, or can also be obtained from molding. It has the drawback of limiting the tilting amplitude to a well-defined value, without proposing intermediate values, adaptable for example according to the progress of the child's balance.
On a alors proposé, par exemple dans le document US-A-3 331 631, un jouet ou une chaise pour bébé susceptible également de basculer, comportant deux longerons présentant à chacune de leurs deux extrémités une came, destinée à limiter l'amplitude du basculement. Dans une première forme de réalisation, cette came est susceptible de pivoter autour du longeron de section circulaire, de sorte que, lorsqu'elle est soumise aux efforts engendrés par le basculement proprement dit, elle pivote autour du longeron, de sorte qu'une nouvelle fois, aucune position intermédiaire de la came ne peut être obtenue, et partant, aucune amplitude intermédiaire de basculement ne peut être atteinte. Ce système fonctionne donc à nouveau selon deux amplitudes de basculement possibles, à savoir selon une première position des cames, totalement pivotées autour des longerons, et permettant une amplitude maximum, et une seconde position, dans laquelle les cames viennent en butée immédiate avec le sol, interdisant ou limitant fortement le basculement. Dans une seconde forme de réalisation, la came peut être bloquée en position intermédiaire au moyen d'un anneau, susceptible de coulisser le long du longeron cylindrique. Mais il n'est pas proposé de systèmes susceptibles de faire varier le degré d'amplitude, à la fois simple à mettre en oeuvre et fiable.It was then proposed, for example in document US-A-3,331,631, a toy or a baby chair also capable of tilting, comprising two side members having at each of their two ends a cam, intended to limit the amplitude of the tilting. In a first embodiment, this cam is capable of pivoting around the cross member of section circular, so that, when it is subjected to the forces generated by the actual tilting, it pivots around the beam, so that once again, no intermediate position of the cam can be obtained, and therefore, no amplitude Tipping intermediary cannot be reached. This system therefore works again according to two possible tilting amplitudes, namely according to a first position of the cams, fully pivoted around the side members, and allowing a maximum amplitude, and a second position, in which the cams come into immediate abutment with the ground. , strongly prohibiting or limiting tilting. In a second embodiment, the cam can be locked in the intermediate position by means of a ring, capable of sliding along the cylindrical spar. However, systems are not proposed which are capable of varying the degree of amplitude, which is both simple to implement and reliable.
L'invention vise à pallier ces inconvénients. Elle propose une bascule, dont on peut faire varier l'amplitude de manière simple et progressive. Cette bascule, notamment pour jouet, comprend deux longerons parallèles arqués, solidaires l'un de l'autre, chaque longeron comportant au voisinage de ses deux extrémités une came articulée. Cette bascule sur laquelle vient se positionner l'élément porteur, notamment un camion, un cheval, etc...., peut être rapportée sous le jouet, ou elle est monobloc avec le jouet. Elle se caractérise en ce que chaque came est susceptible de s'étendre de manière réglable et progressive selon le plan vertical à l'aplomb du longeron correspondant par pivotement autour d'un axe horizontal intégré dans ledit longeron, le réglage de la came s'effectuant au moyen d'une poignée ménagée au niveau de la face latérale exterieure du longeron, solidaire de la came selon l'axe d'articulation de cette dernière.The invention aims to overcome these drawbacks. It offers a rocker, the amplitude of which can be varied in a simple and progressive manner. This rocker, in particular for a toy, comprises two parallel arched longitudinal members, integral with one another, each longitudinal member comprising in the vicinity of its two ends an articulated cam. This rocker on which the carrier element is positioned, in particular a truck, a horse, etc., can be attached under the toy, or it is integral with the toy. It is characterized in that each cam is capable of extending in an adjustable and progressive manner along the vertical plane perpendicular to the corresponding spar by pivoting around a horizontal axis integrated in said spar, the adjustment of the cam is effecting by means of a handle formed at the level of the external lateral face of the spar, secured to the cam along the axis of articulation of the latter.
En d'autres termes, l'invention consiste à munir chacune des extrémités des deux longerons constitutifs de la bascule d'une came, réglable en débattement au moyen d'une poignée extérieure, de sorte à pouvoir limiter de manière réglable l'amplitude de basculement des longerons et donc de la bascule.In other words, the invention consists in providing each of the ends of the two longitudinal members constituting the rocker with a cam, adjustable in travel by means of an external handle, so as to be able to limit in an adjustable manner the amplitude of tilting of the side members and therefore of the rocker.
Selon une forme avantageuse de l'invention, lorsque la bascule est en position d'amplitude maximum, la came est complètement escamotable à l'intérieur du longeron.According to an advantageous form of the invention, when the rocker is in the position of maximum amplitude, the cam is completely retractable inside the spar.
Avantageusement, l'ensemble constitué par la poignée et la came est monobloc, le longeron étant constitué de deux parties, soudées au niveau d'une ligne de soudure après mise en place de l'ensemble came/poignée.Advantageously, the assembly constituted by the handle and the cam is in one piece, the spar consisting of two parts, welded at a weld line after the cam / handle assembly has been put in place.
Afin de figer les différents positionnements possibles de la came, pour régler l'amplitude de basculement, la poignée est munie d'un téton, qui coopère avec des orifices ménagés sur la face latérale exterieure du longeron, avantageusement situés selon un arc de cercle et positionnés à 20 ° les uns des autres.In order to freeze the different possible positions of the cam, to adjust the tilting amplitude, the handle is provided with a stud, which cooperates with orifices provided on the external lateral face of the spar, advantageously located in an arc of a circle and positioned at 20 ° from each other.
Afin de maintenir la poignée en place au niveau de la position de réglage souhaitée, on munit la came d'un ressort élastique, destiné à s'opposer au retrait de la poignée et notamment du téton hors de l'orifice de règlage.In order to keep the handle in place at the desired adjustment position, the cam is provided with an elastic spring, intended to oppose the withdrawal of the handle and in particular of the stud from the adjustment orifice.
Avantageusement, le ressort est un ressort à lame, solidaire de la came et issu du moulage.Advantageously, the spring is a leaf spring, integral with the cam and resulting from molding.
Selon une caractéristique de l'invention, les cames sont positionnées symétriquement par rapport à l'axe d'équilibre du longeron et alignées deux à deux d'un longeron à l'autre.According to a characteristic of the invention, the cams are positioned symmetrically with respect to the axis of equilibrium of the beam and aligned two by two from one beam to the other.
Les cames sont réalisées en un matériau résistant, par exemple en polypropylène ou polyoxyméthylène. En effet, ces matières faciles à mouler présentent la résistance nécessaires à l'usure et aux contraintes engendrées lors des basculements.The cams are made of a resistant material, for example polypropylene or polyoxymethylene. These easy-to-mold materials have the resistance necessary for wear and for the stresses generated during tilting.
La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront de l'exemple de réalisation qui suit donné à titre indicatif et non limitatif à l'appui des figures annexées.The manner in which the invention can be implemented and the advantages which result therefrom will emerge from the example of embodiment which follows, given by way of non-limiting illustration in support of the appended figures.
La figure 1 est une représentation schématique d'une vue latérale de la bascule conformément à l'invention.Figure 1 is a schematic representation of a side view of the scale according to the invention.
La figure 2 est une représentation schématique vue du dessus d'un longeron de l'invention.Figure 2 is a schematic representation seen from above of a spar of the invention.
La figure 3 est une représentation schématique en coupe de la came munie de sa poignée conformément à l'invention.Figure 3 is a schematic sectional representation of the cam provided with its handle according to the invention.
Selon l'invention, et comme on l'a représenté sur la figure 1, la bascule est constituée de deux longerons parallèles (1) solidaires entre eux, de forme arquée, et reposant sur le sol du côté de leur courbure. Ces deux longerons constituant ainsi une bascule, sont destinés à recevoir un élément portant, tel que par exemple un camion, un cheval, ou tout type de dispositif équivalent, destiné à recevoir un enfant. On a par exemple représenté par la référence (3) un tel camion ainsi que ses roues (2) qui sont recues dans des évidements prévus à cet effet dans lesdits longerons.According to the invention, and as shown in FIG. 1, the lever consists of two parallel beams (1) integral with each other, of arcuate shape, and resting on the ground on the side of their curvature. These two side members thus constituting a rocker, are intended to receive a bearing element, such as for example a truck, a horse, or any type of equivalent device, intended to receive a child. For example, there is shown by reference (3) such a truck as well as its wheels (2) which are received in recesses provided for this purpose in said longitudinal members.
De la sorte, une fois en place dans ces logements, le dispositif porteur peut ainsi basculer compte tenu de la forme arquée des longerons et ce, de manière connue.In this way, once in place in these housings, the carrier device can thus tilt in view of the arched shape of the side members, in a known manner.
Selon une caractéristique importante de l'invention, chacun des longerons reçoit au niveau de ses extrémités, symétriquement par rapport au plan d'équilibre référencé (10), une came (4) de forme ovale, destinée à se déployer dans le plan vertical à l'aplomb du longeron. Cette came est articulée au niveau d'un axe d'articulation horizontal (5), susceptible de permettre un réglage de son extension dans ledit plan vertical contenant le longeron (1) considéré, tel qu'on peut le voir nettement sur la figure 1, où différentes positions possibles de la came (4) ont été représentées. Cette came est destinée à réduire l'amplitude de basculement des longerons (1) entre deux positions extrêmes, à savoir une première position dans laquelle les cames antérieures et postérieures sont verticales et prennent appui sur le sol, de sorte que l'ensemble de la bascule est bloqué et ne peut plus basculer, et une position totalement escamotée à l'intérieur du longeron, permettant alors le basculement maximum. Entre ces deux positions extrêmes, les cames (4) peuvent être réglées selon différentes positions intermédiaires, et ce au moyen d'une poignée (7), telle que mieux représentée sur la figure 3. Cette poignée (7), ménagée sur la paroi latérale extérieure du longeron, est solidaire de la came (4) au niveau de l'une de ses extrémités par un axe (11), lui-même colinéaire avec l'axe (5) d'articulation de la came (4) sur le longeron (1). La poignée (7) comporte au niveau de sa face en regard dudit longeron un téton (8), ou organe équivalent, destiné à coopérer avec des orifices (6) ménagés dans lla face latérale extérieure du longeron (1).According to an important characteristic of the invention, each of the side members receives at its ends, symmetrically with respect to the equilibrium plane referenced (10), a cam (4) of oval shape, intended to deploy in the vertical plane at vertical to the spar. This cam is articulated at a horizontal articulation axis (5), capable of allowing its extension to be adjusted in said vertical plane containing the longitudinal member (1) considered, as can be clearly seen in FIG. 1 , where different possible positions of the cam (4) have been shown. This cam is intended to reduce the amplitude of tilting of the side members (1) between two extreme positions, namely a first position in which the anterior and posterior cams are vertical and bear on the ground, so that the whole of the rocker is blocked and can no longer tilt, and a fully retracted position inside the side member, allowing maximum tilting. Between these two extreme positions, the cams (4) can be adjusted according to different intermediate positions, by means of a handle (7), as best shown in FIG. 3. This handle (7), formed on the wall lateral lateral side member, is integral with the cam (4) at one of its ends by an axis (11), itself collinear with the axis (5) of articulation of the cam (4) on the side member (1). The handle (7) has at its face opposite said spar a stud (8), or equivalent member, intended to cooperate with orifices (6) formed in the external lateral face of the spar (1).
De la sorte, cette poignée (7) articulée et solidaire de la came (4), décrit un secteur de disque, et donc le téton correspondant (8), situé au niveau de l'une des extrémités de ladite poignée (7), opposée à celle recevant l'axe d'articulation (11), décrit un arc de cercle pouvant typiquement atteindre 80°. Avantageusement, on perce les orifices (6) au niveau du longeron tous les 20 ° afin d'avoir environ trois positions intermédiaires de réglage possibles. Il va sans dire que l'on peut en prévoir plus, il suffit pour cela de prévoir davantage d'orifices (6), espacés d'une distance moindre.In this way, this articulated handle (7) integral with the cam (4), describes a disk sector, and therefore the corresponding stud (8), located at one of the ends of said handle (7), opposite to that receiving the articulation axis (11), describes an arc of circle which can typically reach 80 °. Advantageously, the holes (6) are drilled at the side member every 20 ° so as to have approximately three possible intermediate adjustment positions. It goes without saying that more can be provided, it suffices for this to provide more orifices (6), spaced by a lesser distance.
En outre, afin d'assurer la stabilité d' une position déterminée de réglage de basculement, on munit l'ensemble came/poignée d'un ressort (9), induisant en l'absence de contrainte, le maintien du téton en place dans l'orifice choisi. Le ressort (9) exerce son action en compression entre la came (4) et la face latérale intérieure du longeron (1). De la sorte, il tend à s'opposer à l'écartement de la poignée (7) de la face latérale extérieure dudit longeron, et donc, à la sortie du téton (8) hors de l'orifice (6) sélectionné. Le ressort (9) est avantageusement choisi de telle sorte que la poussée qu'il exerce soit suffisamment importante pour interdire la sélection de l'orifice (6) par les enfants, susceptibles de jouer avec ce jouet.In addition, in order to ensure the stability of a determined tilting adjustment position, the cam / handle assembly is provided with a spring (9), inducing in the absence of stress, the retention of the stud in place in the chosen opening. The spring (9) exerts its compression action between the cam (4) and the inner lateral face of the beam (1). In this way, it tends to oppose the spacing of the handle (7) of the external lateral face of said spar, and therefore, at the outlet of the stud (8) outside the orifice (6) selected. The spring (9) is advantageously chosen so that the thrust it exerts is large enough to prohibit the selection of the orifice (6) by children, likely to play with this toy.
Selon une forme particulièrement avantageuse de l'invention, ce ressort (9) est issu du moulage et est solidaire de la came (4), tel qu'on l'a clairement représenté sur la figure 3. Ce ressort à lame à effet mémoire induit donc le maintien de la poignée (7) dans la position voulue.According to a particularly advantageous form of the invention, this spring (9) comes from molding and is integral with the cam (4), as clearly shown in FIG. 3. This leaf spring with memory effect therefore induces the maintenance of the handle (7) in the desired position.
Selon une autre caractéristique avantageuse de l'invention, l'ensemble constitué par la came (4), l'axe (11), la poignée (7), le téton (8) et le ressort (9) est monobloc et issu du moulage. Pour ce faire, on met en place l'ensemble des deux cames à savoir antérieure et postérieure pour un longeron donné, longeron alors constitué en deux parties que l'on vient alors souder une fois l'ensemble de réglage par came mis en place.According to another advantageous characteristic of the invention, the assembly constituted by the cam (4), the pin (11), the handle (7), the stud (8) and the spring (9) is in one piece and comes from the molding. To do this, we put in place the set of two cams, namely the front and rear for a given spar, a spar then made up of two parts which are then welded once the adjustment assembly by cam is put in place.
Avantageusement, l'ensemble constitué par la came et la poignée est réalisé en polypropylène, et plus particulièrement en polyoxyméthylène, vendu sous la marque déposée DELRIN (DUPONT DE NEMOURS).Advantageously, the assembly constituted by the cam and the handle is made of polypropylene, and more particularly of polyoxymethylene, sold under the registered trademark DELRIN (DUPONT DE NEMOURS).
Selon l'invention, les quatre cames à savoir les cames antérieures et postérieures de chacun des deux longerons sont rigoureusement identiques, simplifiant de la sorte la réalisation du dispositif. Elles sont comme déjà dit situées de part et d'autre et symétriquement par rapport au plan (10) d'équilibre de chaque longeron, et parallèles deux à deux entre les deux longerons. L'épaisseur de chacune des cames est voisine de 14 mm, chaque came étant ainsi suffisamment rigide pour opposer la résistance nécessaire au basculement, compte tenu du poids de l'enfant.According to the invention, the four cams, namely the anterior and posterior cams of each of the two side members, are strictly identical, thereby simplifying the production of the device. They are as already said located on either side and symmetrically with respect to the plane (10) of equilibrium of each beam, and parallel two by two between the two beams. The thickness of each of the cams is close to 14 mm, each cam thus being rigid enough to provide the resistance necessary for tilting, taking into account the weight of the child.
On conçoit ainsi qu'un tel dispositif permet de faire varier l'amplitude de basculement d'un porteur à bascule, et ce en fonction des progrès réalisés par l'enfant notamment au niveau de son équilibre.It is thus conceivable that such a device makes it possible to vary the amplitude of tilting of a rocking carrier, and this as a function of the progress made by the child in particular in terms of his balance.
En effet, l'avantage de tels jouets consiste en ce que l'on recherche une certaine instabilité, qui certes augmente les risques de chute lorsque l'amplitude de basculement devient trop importants, mais qui en contrepartie développe le sens de l'équilibre de l'enfant. Au moyen d'une telle bascule réglable, on limite de la sorte considérablement les risques de chute, compte tenu que l'on peut adapter cette amplitude de basculement en fonction des progrès effectués par l'enfant.Indeed, the advantage of such toys is that we are looking for a certain instability, which certainly increases the risk of falling when the tilting amplitude becomes too large, but which in return develops the sense of balance. the child. By means of such an adjustable tilting device, the risk of falling is thus considerably limited, given that this amplitude of tilting can be adapted according to the progress made by the child.
En outre, compte tenu de la réalisation particulièrement simple de ce dispositif de réglage et de sa mise en place aisée, il s'avère tout à fait adapté à tous les ensembles porteurs à bascule.In addition, given the particularly simple embodiment of this adjustment device and its easy installation, it turns out to be quite suitable for all rocking carrier assemblies.
Enfin, compte tenu du réglage individuelle de chacune des cames, il est possible d'obtenir par ce dispositif une instabilité latérale du jouet porteur, en réglant de manière différente les cames d'un longeron à l'autre.Finally, taking into account the individual adjustment of each of the cams, it is possible by this device to obtain lateral instability of the carrier toy, by adjusting the cams from one spar to the other.
