Description

VEHICULE DE TAILLE REDUITE SERVANT DE PORTEUR POUR REDUCED-SIZE VEHICLE AS CARRIER FOR
ENFANTCHILD
Domaine Technique L'invention se rattache au domaine du jouet pour enfant, précisément des véhicules de petite taille généralement appelés « porteurs ».Technical Field The invention relates to the field of children's toys, specifically small vehicles generally called "carriers".
Elle concerne plus particulièrement la présence de repose-pieds latéraux escamotables, permettant notamment l'adaptation d'un tel porteur à la croissance de l'enfant.It relates more particularly to the presence of retractable lateral footrests, in particular allowing the adaptation of such a carrier to the growth of the child.
Techniques antérieuresPrevious techniques
De façon connue, les porteurs sont des véhicules de petite taille, généralement à quatre roues, destinés à être utilisés par des enfants dont l'âge varie entre quelques mois et quelques années.In known manner, the carriers are small vehicles, generally with four wheels, intended for use by children whose age varies between a few months and a few years.
Un porteur possède généralement un châssis comportant quatre roues et un siège sur lequel s'assoit l'enfant, en laissant pendre ses jambes de chaque côté.A carrier generally has a chassis with four wheels and a seat on which the child sits, letting his legs hang on each side.
Lorsque l'enfant est très jeune, ses pieds ne reposent pas par terre et le mouvement est assuré par la poussée exercée par l'arrière par un adulte. Cette poussée peut être exercée soit directement sur le porteur, soit éventuellement par l'intermédiaire d'une canne évitant à l'adulte de se baisser.When the child is very young, his feet do not rest on the ground and the movement is ensured by the push exerted by the rear by an adult. This thrust can be exerted either directly on the wearer, or possibly via a cane preventing the adult from bending down.
Lorsque l'enfant est suffisamment grand, ses pieds reposent par terre lorsqu'il est assis dans le porteur et il peut en assurer lui-même la propulsion.When the child is big enough, his feet rest on the ground when he is seated in the carrier and he can propel it himself.
Un problème se pose à un âge intermédiaire où l'enfant a ses pieds qui reposent par terre ou à proximité des roues et ne souhaite pas se déplacer par lui- même, mais bien être poussé. Dans ce cas, on conçoit que le fait que les pieds reposent ou affleurent au niveau du sol, les fait frotter lorsque le porteur avance, et peut provoquer le coincement des pieds au niveau des roues.A problem arises at an intermediate age where the child has his feet resting on the ground or close to the wheels and does not want to move by himself, but rather be pushed. In this case, it is understood that the fact that the feet rest or are flush with the ground, makes them rub when the carrier advances, and can cause the feet to jam at the wheels.
On a donc déjà proposé d'équiper certains porteurs de repose-pieds latéraux qui sont vissés sur le châssis. Si ce type de repose-pied présente l'avantage de permettre à l'enfant d'immobiliser ses pieds lorsqu'il est poussé, ils ont en revanche l'inconvénient majeur de devoir être démontés lorsque l'on ne souhaite plus s'en servir. Cela se traduit automatiquement par des manipulations fastidieuses et peu pratiques ainsi que par la nécessité de ranger et de conserver le repose-pied pour une utilisation ultérieure.It has therefore already been proposed to equip certain carriers with lateral footrests which are screwed onto the chassis. If this type of footrest has the advantage of allowing the child to immobilize his feet when pushed, they have however the major drawback of having to be dismantled when you no longer wish to use it. This automatically results in tedious and inconvenient handling as well as the need to store and keep the footrest for later use.
Dans certaines solutions, on a déjà proposé d'associer les deux repose- pieds en un seul élément transversal qui passe sous le châssis en y étant fixé. De cette manière, les deux repose-pieds se démontent en une seule opération, mais conservent néanmoins les inconvénients précités.In some solutions, it has already been proposed to combine the two footrests in a single transverse element which passes under the chassis while being attached to it. In this way, the two footrests can be dismantled in a single operation, but nevertheless retain the aforementioned drawbacks.
On conçoit donc qu'un problème se pose lorsque le porteur est utilisé par un enfant qui indifféremment se propulse par ses propres forces, ou est poussé par un adulte. Un problème que se propose donc de résoudre l'invention est celui de la reconfiguration aisée d'un porteur comportant des repose-pieds.It is therefore understandable that a problem arises when the carrier is used by a child who indifferently propels himself by his own strength, or is pushed by an adult. A problem which the invention therefore proposes to solve is that of the easy reconfiguration of a carrier comprising footrests.
Par ailleurs, les porteurs existants équipés de repose-pieds présentent ces derniers nécessairement à un niveau intermédiaire entre les roues avant et arrière. Cela oblige l'enfant à plier ses genoux et lui empêche d'adopter une position peu confortable.Furthermore, existing carriers fitted with footrests necessarily present these at an intermediate level between the front and rear wheels. This forces the child to bend his knees and prevents him from adopting an uncomfortable position.
Un second problème que se propose de résoudre l'invention est celui de l'ergonomie dans le positionnement des repose-pieds.A second problem which the invention proposes to solve is that of ergonomics in the positioning of the footrests.
Exposé de l'invention L'invention concerne donc un véhicule de taille réduite servant de porteur pour enfant, présentant un châssis comportant quatre roues et un siège sur lequel s'assoit l'enfant.Disclosure of the Invention The invention therefore relates to a reduced size vehicle serving as a carrier for a child, having a chassis comprising four wheels and a seat on which the child sits.
Ce porteur se caractérise en ce qu'il comporte également des repose-pieds latéraux, qui peuvent adopter deux positions, à savoir :This carrier is characterized in that it also includes lateral footrests, which can take two positions, namely:
_ une position escamotée dans laquelle lesdits repose-pieds se trouvent disposés sous le châssis ;_ a retracted position in which said footrests are located under the chassis;
_ et une position active dans laquelle lesdits repose-pieds se trouvent disposés latéralement par rapport au châssis, de manière à supporter les pieds de l'enfant. Autrement dit, le porteur conforme à l'invention présente des repose-pieds qui sont camouflés sous le châssis lorsqu'ils ne sont pas utilisés et qui, au contraire, sont déployés lorsqu'il en est besoin._ And an active position in which said foot rests are arranged laterally with respect to the chassis, so as to support the child's feet. In other words, the carrier according to the invention has footrests which are camouflaged under the chassis when they are not in use and which, on the contrary, are deployed when necessary.
Pour assurer une ergonomie optimale, dans une forme préférée de l'invention, la position active du repose-pied se trouve sensiblement au niveau longitudinal des roues avant, ce qui permet à l'enfant de garder ses jambes orientées vers l'avant, et non pas à l'aplomb de son tronc comme dans les porteurs existants.To ensure optimal ergonomics, in a preferred form of the invention, the active position of the footrest is located substantially at the longitudinal level of the front wheels, which allows the child to keep his legs oriented forward, and not plumb with its trunk as in the existing carriers.
Dans une forme préférée de l'invention, le repose-pied présente une forme allongée correspondant sensiblement à la taille d'une semelle de chaussure, ce qui le rend particulièrement robuste et pratique.In a preferred form of the invention, the footrest has an elongated shape corresponding substantially to the size of a shoe sole, which makes it particularly robust and practical.
Dans une autre forme de réalisation, le repose-pied est monté pivotant par rapport à une première extrémité d'une bielle, dont l'autre extrémité est pivotante par rapport au châssis, de telle sorte que lorsque la bielle pivote, le repose-pied peut passer de la position escamotée située sous le châssis entre les roues avant et arrière, jusqu'à la position active, située en regard de la roue avant.In another embodiment, the footrest is pivotally mounted relative to a first end of a connecting rod, the other end of which is pivotable relative to the frame, so that when the connecting rod pivots, the footrest can move from the retracted position located under the chassis between the front and rear wheels, to the active position, located opposite the front wheel.
Autrement dit, cette disposition mécanique permet à la fois d'allier l'ergonomie et la compacité du porteur. En effet, lorsque le repose-pied est en position escamotée, la bielle et le repose-pied sont regroupés sous le châssis en occupant un volume minimum. A l'inverse, lorsque le repose-pied est sorti, il vient jusqu'en regard de la roue avant, ce qui assure les avantages précités.In other words, this mechanical arrangement makes it possible both to combine the ergonomics and the compactness of the carrier. Indeed, when the footrest is in the retracted position, the connecting rod and the footrest are grouped under the chassis occupying a minimum volume. Conversely, when the footrest is out, it comes up to the front wheel, which provides the above advantages.
Avantageusement, en pratique, l'axe d'articulation du repose-pied par rapport à la bielle peut pénétrer dans deux logements prévus à cet effet sous le châssis, de manière à assurer un verrouillage du repose-pied par rapport audit châssis. Autrement dit, le mécanisme d'articulation de la bielle et du repose-pied permet de bloquer ces deux éléments par rapport au châssis, ce qui augmente la sécurité. Les risques de coincement des doigts ou de toute partie de l'enfant sont donc éliminés puisque l'actio nement des moyens de verrouillage ne peut être obtenu qu'en retournant le porteur pour avoir accès à l'axe de verrouillage.Advantageously, in practice, the axis of articulation of the footrest relative to the connecting rod can penetrate into two housings provided for this purpose under the chassis, so as to ensure a locking of the footrest relative to said chassis. In other words, the articulation mechanism of the connecting rod and the footrest makes it possible to block these two elements with respect to the chassis, which increases safety. The risk of entrapment of the fingers or of any part of the child is therefore eliminated since the actuation of the locking means can only be obtained by turning the carrier over to gain access to the locking axis.
Bien entendu, l'invention n'est pas limitée à ces seules formes de réalisation dans lesquelles le repose-pied est articulé, mais couvre d'autres variantes non décrites en détail dans lesquelles le repose-pied peut être associé à un mécanisme de coulissement ou de basculement autour d'un axe longitudinal, pour que le repose-pied soit escamotable et puisse parvenir jusqu'à l'aplomb de la roue avant.Of course, the invention is not limited to these only embodiments in which the footrest is articulated, but covers other variants not described in detail in which the footrest can be associated with a sliding mechanism or tilting around a longitudinal axis, so that the footrest is retractable and can reach the vertical alignment of the front wheel.
Avantageusement, en pratique, chaque bielle est montée pivotante par rapport au châssis autour d'un fut solidaire du châssis, et montée sous ce dernier.Advantageously, in practice, each connecting rod is pivotally mounted relative to the chassis around a barrel secured to the chassis, and mounted under the latter.
Dans une forme particulière de réalisation, le porteur comporte également une pièce de liaison reliant les deux extrémités inférieures des deux fûts en emprisonnant les deux bielles.In a particular embodiment, the carrier also includes a connecting piece connecting the two lower ends of the two barrels by trapping the two connecting rods.
Avantageusement, en pratique, chaque repose-pied peut présenter : 4 une zone de réception du pied ;Advantageously, in practice, each footrest can have: 4 a foot reception area;
4 une oreille latérale venant s'encastrer dans un évidement prévu à cet effet au niveau d'une extrémité de la bielle.4 a lateral ear coming to be embedded in a recess provided for this purpose at one end of the connecting rod.
On optimise de la sorte la compacité de l'ensemble tout en conservant une robustesse suffisante.In this way, the compactness of the assembly is optimized while maintaining sufficient robustness.

Manière de réaliser l'invention Comme déjà dit, la présente invention concerne un véhicule de petite taille, également appelé « porteur », qui comporte un mécanisme de repose-pieds escamotable.Manner of Carrying Out the Invention As already stated, the present invention relates to a small vehicle, also called a “carrier”, which includes a retractable footrest mechanism.
Comme illustré à la figure 1, un tel porteur comprend un châssis (2) qui peut être constitué d'une coque en matière plastique, dont la configuration définit la majorité des éléments du porteur, à savoir le capot (3) et les ailes avant (4,5), le siège (11) et les ailes arrière (7,8).As illustrated in FIG. 1, such a carrier comprises a chassis (2) which may consist of a plastic shell, the configuration of which defines the majority of the elements of the carrier, namely the cover (3) and the front wings (4,5), the seat (11) and the rear fenders (7,8).
Différents éléments additionnels peuvent être ajoutés sur cette coque ou châssis, en fonction des propriétés et des fonctions souhaitées, mais qui n'entrent pas dans le cadre de l'invention et ne seront donc pas décrits plus en détail.Different additional elements can be added to this shell or chassis, depending on the desired properties and functions, but which do not fall within the scope of the invention and will therefore not be described in more detail.
Dans la forme illustrée à la figure 2, le mécanisme de repose-pied comprend le repose-pied (10) proprement dit ainsi qu'une bielle (12) montée pivotante par rapport au châssis.In the form illustrated in Figure 2, the footrest mechanism comprises the footrest (10) itself and a connecting rod (12) pivotally mounted relative to the frame.
A une première extrémité (13), la bielle (12) est percée de manière à être traversée par un fut solidaire du dessous du châssis (2).At a first end (13), the connecting rod (12) is pierced so as to be crossed by a barrel secured to the underside of the chassis (2).
L'autre extrémité (15) de la bielle (12) reçoit un axe d'articulation (20) qui la relie avec le repose-pied (10) proprement dit. Le repose-pied (10) comporte une zone de réception (21) du pied, de forme allongée, pour recevoir l'appui du pied. Cette zone de réception (21) du pied se prolonge latéralement par une oreille latérale (22) présentant une ouverture (23) laissant passer l'axe d'articulation (20) de la bielle par rapport au repose-pied (10). Les deux mécanismes de repose-pied sont symétriques par rapport au plan longitudinal médian (P) du porteur. Les deux fûts ((14,14') présentent une extrémité renflée (26) destinée à venir s'encastrer dans une ouverture (17) prévue à cet effet sur une plaque transversale (28). La plaque transversale (28) est commune aux deux fûts (14,14') de manière à emprisonner les deux bielles droite (12') et gauche (12) et éviter que ces dernières ne s'échappent des fûts (14,14'). La mise en place de la plaque transversale (28) peut se faire par force, ou par tout autre moyen de vissage approprié.The other end (15) of the connecting rod (12) receives a hinge pin (20) which connects it with the footrest (10) proper. The footrest (10) has a reception area (21) of the foot, of elongated shape, for receiving the support of the foot. This reception zone (21) of the foot is extended laterally by a lateral ear (22) having an opening (23) allowing the articulation axis (20) of the connecting rod to pass relative to the footrest (10). The two footrest mechanisms are symmetrical with respect to the median longitudinal plane (P) of the wearer. The two barrels ((14,14 ') have a bulged end (26) intended to be fitted into an opening (17) provided for this purpose on a transverse plate (28). The transverse plate (28) is common to two barrels (14,14 ') so as to trap the two right (12') and left (12) connecting rods and prevent the latter from escaping from the barrels (14,14 '). transverse (28) can be done by force, or by any other suitable screwing means.
La longueur de la bielle (12) est déterminée de telle sorte que l'axe d'articulation (20) avec le repose-pied proprement dit, se trouve à proximité du bord du châssis. De la sorte, le repose-pied (10) peut être suffisamment avancé pour se trouver en regard de la roue avant (6). La longueur de la bielle (12) permet également de déporter latéralement le repose-pied (10) pour optimiser l'ergonomie du porteur. La longueur de la bielle (12) est également déterminée pour occuper un encombrement minimum sous le châssis (2). L'emplacement du fut (14) et donc du point de pivotement de la bielle (12) par rapport au châssis (2), est déterminé pour autoriser le mouvement optimal du repose-pied (10). Ce dernier passe de la situation localisée entre les roues avant (6) et arrière (9) en configuration escamotée, tel qu'illustré à la figure 3, jusqu'à la situation illustrée à la figure 4 dans laquelle la bielle (12) est dans sa position la plus avant.The length of the connecting rod (12) is determined so that the axis of articulation (20) with the footrest itself is located near the edge of the chassis. In this way, the footrest (10) can be advanced enough to be opposite the front wheel (6). The length of the connecting rod (12) also makes it possible to offset the footrest (10) laterally to optimize the ergonomics of the wearer. The length of the connecting rod (12) is also determined to occupy a minimum space under the chassis (2). The location of the barrel (14) and therefore of the pivot point of the connecting rod (12) relative to the frame (2), is determined to allow the optimal movement of the footrest (10). The latter goes from the situation located between the front (6) and rear (9) wheels in the retracted configuration, as illustrated in FIG. 3, to the situation illustrated in FIG. 4 in which the connecting rod (12) is in its most forward position.
L'articulation du repose-pied (10) par rapport à la bielle (12) est assurée autour d'un axe (20) qui assure également la fonction de verrouillage en position par rapport au châssis (2).The articulation of the footrest (10) relative to the connecting rod (12) is ensured around an axis (20) which also provides the locking function in position relative to the frame (2).
Plus précisément, comme illustré à la figure 6, cet axe (20) comporte une tête (30) présentant une fente (31) (cf. figure 2) permettant d'en assurer la rotation au moyen d'un objet très simple, tel qu'une pièce de monnaie, et ne nécessitant pas d'outil particulier tel qu'un tournevis. La tête (30) de l'axe (20) est reliée au corps (32) de l'axe proprement dit qui traverse la bielle (12) et l'oreille (22) du repose- pied. A l'extrémité opposée à la tête, cet axe (20) comporte un filetage (33) qui peut venir se visser dans des logements prévus à cet effet sous le châssis (2). Le dessous du châssis (2) comporte deux paires de logements (34,35), à savoir un logement arrière (34) (cf. fig. 4) qui reçoit l'axe d'articulation (20) lorsque la bielle (12) est en position arrière et le repose-pied en position escamotée, comme illustré à la figure 3, et un logement avant (35) (cf. fig 3), qui reçoit l'axe d'articulationMore precisely, as illustrated in FIG. 6, this axis (20) comprises a head (30) having a slot (31) (cf. FIG. 2) making it possible to rotate it by means of a very simple object, such as than a coin, and not requiring any special tool such as a screwdriver. The head (30) of the axle (20) is connected to the body (32) of the axle itself which passes through the connecting rod (12) and the ear (22) of the footrest. At the end opposite the head, this axis (20) has a thread (33) which can be screwed into housings provided for this purpose under the chassis (2). The underside of the chassis (2) has two pairs of housings (34,35), namely a rear housing (34) (cf. fig. 4) which receives the hinge pin (20) when the connecting rod (12) is in the rear position and the footrest in the retracted position, as shown in Figure 3, and a front housing (35) (see fig 3), which receives the hinge pin
(20) lorsque le repose-pied (10) est en position active comme illustré à la figure 4.(20) when the footrest (10) is in the active position as illustrated in FIG. 4.
De la sorte, il est impossible au mécanisme du repose-pied de s'escamoter de façon inopinée. Les risques de coincement du pied de l'enfant sont donc inexistants. Le déverrouillage de la position reste très simple puisqu'il suffit à un adulte de retourner le porteur, de dévisser l'axe (20) en utilisant la fente appropriée (31), pour reconfigurer le repose-pied dans l'une des positions illustrées aux figures 3 ou 4.In this way, it is impossible for the mechanism of the footrest to retract unexpectedly. The risk of jamming the child's foot is therefore nonexistent. Unlocking the position remains very simple since it is sufficient for an adult to turn the wearer over, to unscrew the axle (20) using the appropriate slot (31), to reconfigure the footrest in one of the positions illustrated in Figures 3 or 4.
Comme illustré aux figures 5 et 6, les bielles (12) et les repose-pied (10) sont réalisés en matière plastique, par exemple injectée, et présentent des épaisseurs et des géométries appropriées pour obtenir la robustesse souhaitée. Plus précisément, la bielle (12) telle qu'illustrée aux figures 5 et 6 présente à son extrémité articulée sur le repose-pied (10), un évidement (37) destiné à recevoir l'oreille latérale (22) du repose-pied (10), de manière à ce que l'ensemble bielle/repose-pied présente une épaisseur limitée, égale à celle du repose-pied (10). Le galbe (38) de l' évidement (37) est déterminé pour permettre l'encastrement du galbe complémentaire de l'oreille (22) du repose-pied (10) lorsque ce dernier est en position escamotée.As illustrated in FIGS. 5 and 6, the connecting rods (12) and the footrests (10) are made of plastic material, for example injected, and have suitable thicknesses and geometries to obtain the desired robustness. More specifically, the connecting rod (12) as illustrated in Figures 5 and 6 has at its hinged end on the footrest (10), a recess (37) intended to receive the lateral ear (22) of the footrest (10), so that the connecting rod / footrest assembly has a limited thickness, equal to that of the footrest (10). The curve (38) of the recess (37) is determined to allow the embedding of the complementary curve of the ear (22) of the footrest (10) when the latter is in the retracted position.
Il ressort de ce qui précède que le porteur conforme à l'invention présente de multiples avantages et notamment :It appears from the above that the carrier according to the invention has multiple advantages and in particular:
Φ la position ergonomique du repose-pied situé en regard de la roue avant ; en encombrement minimum du repose-pied sous le véhicule une robustesse importante l'absence de risque de coincement et de pincement de l'enfant puisque le mécanisme n'est verrouillable et déverrouillable que par un adulte qui a accès au dessous du châssis ; Φ the ergonomic position of the footrest located opposite the front wheel; in minimum footprint under the vehicle a significant robustness the absence of risk of jamming and pinching of the child since the mechanism is lockable and unlockable only by an adult who has access to the underside of the chassis;
