Definitions

  • the field of the invention is that of strollers for children. More specifically, the invention relates to a folding stroller, with reduced overall dimensions in the folded position, and the safety of a child transported in a folding stroller.
  • a number of folding children's strollers are already known. Generally, the designers of such folding strollers have the main objective of providing a stroller with a small footprint, when folded.
  • a first technique illustrated for example by patent document FR-1 507 446, consists in folding the stroller in the form of a bundle, the front wheels being at one end of the bundle and the rear wheels at the other end , near the handles. In the folded position, the spacing between the front wheels and the rear wheels is increased, relative to the deployed position. In other words, if folding makes it possible to reduce the overall volume of the stroller, it nevertheless results in an increase in its longitudinal dimension.
  • the hammock, or nacelle, intended to support the child is mounted on two uprights substantially parallel to the push arms. Each of these uprights is integral with a sleeve sliding on the one hand along the front base, and on the other hand along the push arm. Stops are provided to define the location of the sleeves, in the folded position and in the deployed position.
  • Such a stroller provides folding in a very compact volume, compared to other known techniques. However, it is desirable to obtain an even more limited final volume.
  • the problem of congestion is indeed, in certain situations, crucial. This can for example be the case when you want to be able to slide the folded stroller in an automobile or a cupboard (generally at the same time as many other objects ).
  • FR-2 692 162 is also described an advantageous technique of locking the stroller in the deployed position and unlocking to allow return to the folded position. According to this technique, simply rotate a portion of the handlebar of the stroller, then push on the handlebars so that the stroller folds completely.
  • This locking technique is particularly ergonomic and simple to use. However, it introduces a risk of unintentional manipulation of the unlocking mechanism, causing inadvertent folding of the stroller, while a child is still present in the hammock.
  • This situation can moreover generally occur with any locking system. Depending on the case, it can be caused by the person pushing the stroller, temporarily distracted or who acts for example on the inclination of the stroller, or by a child (carried in the stroller or mounted on the back of the stroller). -this). Such untimely folding can also be due to the fact that, following any problem, the locking system jumps or is loose.
  • an objective of the invention is to provide a folding stroller whose size is smaller, in the folded position, than that of known strollers.
  • the invention aims to improve efficiency, in terms of reduction of the size of the stroller described in document FR-2 693 162.
  • Another objective of the invention is to provide such a stroller, having at least the same qualities as known strollers, in terms of safety, comfort, adjustment, etc.
  • Another object of the invention is to provide a folding stroller whose folding and unfolding is done in a direct and simple manner, in a single operation, including for the retaining arch.
  • an objective of the invention is to provide such a stroller equipped with a support arch which: automatically moves into a stable position for maintenance, when the stroller is deployed; folds automatically when folded, without compromising the compactness of the assembly.
  • an objective of the invention is also to provide such a folding stroller which is very compact, in the folded position, despite the presence of a support arch.
  • the invention also aims to provide such a folding stroller, which is a reduced cost, especially with regard to the support arch. 3-3- anti-aliasing security
  • Another object of the invention is to provide a stroller for children which keeps the latter safe, in the event of untimely unlocking of the device for holding the stroller in the deployed position.
  • Another object of the invention is also to provide such a stroller, the safety device of which does not influence the normal operation of folding and unfolding.
  • the invention aims to provide a security device whose operation is transparent to the user.
  • an objective of the invention is to provide such a device which does not make unfolding more complex, which does not risk introducing friction, or even blocking during folding or unfolding, and which does not require any additional manipulation. for the user.
  • Yet another objective of the invention is to provide such a safety device, which does not affect the size of the stroller, in the folded position.
  • the invention also aims to provide such a device which is inexpensive to manufacture, and simple to manufacture, to assemble and to implement.
  • a folding stroller of the type having two push-arms capable of sliding substantially parallel to the legs of the chassis of said stroller , between two extreme positions: a deployed position, in which said push arms are deployed, said stroller developing a hammock ready to receive a child; and a folded position, in which said push arms are at least partially brought back along said legs, so as to reduce the size of said stroller, each of said push arms carrying at least one support element of said hammock, integral with an upper part of said hammock and movable in translation relative to said push arm, on a predetermined portion of the latter.
  • the technique of the invention is based on a new technique, and not obvious, consisting in securing the hammock directly to the push arms, by means of elements movable in translation. This approach is not obvious, in particular because the person skilled in the art considered that he was necessary, to allow optimal folding, to leave the push arms completely free.

Description

Poussette pour enfant, à pliage compact. Stroller for children, compact folding.
1- Domaine de l'invention1- Field of the invention
Le domaine de l'invention est celui des poussettes pour enfant. Plus précisément, l'invention concerne une poussette pliante, à encombrement réduit en position pliée, et la sécurité d'un enfant transporté dans une poussette pliante.The field of the invention is that of strollers for children. More specifically, the invention relates to a folding stroller, with reduced overall dimensions in the folded position, and the safety of a child transported in a folding stroller.
2- Etat de l'art 2-1- pliage compact2- State of the art 2-1- compact folding
On connaît déjà un certain nombre de poussettes pliantes pour enfant. D'une façon générale, les concepteurs de telles poussettes pliantes ont pour objectif principal de fournir une poussette présentant un faible encombrement, lorsqu'elle est pliée.A number of folding children's strollers are already known. Generally, the designers of such folding strollers have the main objective of providing a stroller with a small footprint, when folded.
Une première technique, illustrée par exemple par le document de brevet FR- 1 507 446, consiste à replier la poussette sous la forme d'un fagot, les roues avant se trouvant à une extrémité du fagot et les roues arrière à l'autre extrémité, au voisinage des poignées. En position repliée, l'écartement entre les roues avant et les roues arrière est augmenté, par rapport à la position déployée. En d'autres termes, si le pliage permet de réduire le volume global de la poussette, il se traduit malgré tout par un accroissement de sa dimension longitudinale.A first technique, illustrated for example by patent document FR-1 507 446, consists in folding the stroller in the form of a bundle, the front wheels being at one end of the bundle and the rear wheels at the other end , near the handles. In the folded position, the spacing between the front wheels and the rear wheels is increased, relative to the deployed position. In other words, if folding makes it possible to reduce the overall volume of the stroller, it nevertheless results in an increase in its longitudinal dimension.
Une autre technique, décrite notamment dans le document de brevet FR-2 607 770 (au nom de la Déposante de la présente demande de brevet), est de mettre en oeuvre un pliage à plat. L'écartement entre les roues reste alors inchangé. Dans ce cas, il n'y a pas d'augmentation d'une des dimensions. Cependant, la surface occupée reste importante, et plus précisément identique à la surface occupée en position déployée.Another technique, described in particular in patent document FR-2 607 770 (in the name of the Applicant of the present patent application), is to use flat folding. The distance between the wheels then remains unchanged. In this case, there is no increase in one of the dimensions. However, the surface occupied remains large, and more precisely identical to the surface occupied in the deployed position.
Une technique plus efficace a été développée par la Déposante. Elle est présentée en particulier dans le document de brevet FR-2 693 162. Selon cette technique, décrite plus en détail par la suite en relation avec les figures, les quatre roues (ou ensembles de roues) sont regroupées, en position repliée, à une extrémité d'un fagot opposée à l'extrémité présentant le ou les bras-poussoirs servant au guidage de la poussette.A more effective technique has been developed by the Applicant. It is presented in particular in patent document FR-2 693 162. According to this technique, described in more detail below in relation to the figures, the four wheels (or sets of wheels) are grouped, in the folded position, at one end of a bundle opposite the end presenting the push arm (s) used to guide the stroller.
Ce résultat est obtenu par la combinaison de différents mécanismes et notamment : - deux croisillons formant un X articulé, et permettant le rapprochement ou l'éloignement des deux piètements arrière ; des moyens permettant le coulissement des bras-poussoirs le long des piètements avant correspondants ; une articulation des piètements arrière permettant de ramener ces derniers au voisinage des piètements avant correspondants.This result is obtained by the combination of different mechanisms and in particular: - two cross-pieces forming an articulated X, and allowing the approximation or the distance between the two rear legs; means for sliding the push arms along the corresponding front legs; an articulation of the rear legs making it possible to bring the latter to the vicinity of the corresponding front legs.
Le hamac, ou nacelle, destiné à supporter l'enfant, est monté sur deux montants sensiblement parallèles aux bras-poussoirs. Chacun de ces montants est solidaire d'un manchon coulissant d'une part le long du piètement avant, et d'autre part le long du bras- poussoir. Des butées sont prévues pour définir l'emplacement des manchons, en position pliée et en position déployée.The hammock, or nacelle, intended to support the child, is mounted on two uprights substantially parallel to the push arms. Each of these uprights is integral with a sleeve sliding on the one hand along the front base, and on the other hand along the push arm. Stops are provided to define the location of the sleeves, in the folded position and in the deployed position.
Une telle poussette permet d'obtenir un pliage dans un volume très compact, par rapport aux autres techniques connues. Toutefois, il est souhaitable d'obtenir un volume final encore plus restreint. Le problème de l'encombrement est en effet, dans certaines situations, crucial. Cela peut par exemple être le cas lorsque l'on veut pouvoir glisser la poussette pliée dans une automobile ou un placard (généralement en même temps que de nombreux autres objets...). 2-2- arceau de maintienSuch a stroller provides folding in a very compact volume, compared to other known techniques. However, it is desirable to obtain an even more limited final volume. The problem of congestion is indeed, in certain situations, crucial. This can for example be the case when you want to be able to slide the folded stroller in an automobile or a cupboard (generally at the same time as many other objects ...). 2-2- support bar
Dans le même temps, il est bien sûr souhaitable d'assurer la sécurité de l'enfant transporté dans la poussette. On utilise classiquement des arceaux de maintien, qui se placent devant l'enfant, sensiblement dans un plan horizontal. L'enfant ne risque alors plus de tomber de la poussette, et est protégé de certains chocs.At the same time, it is of course desirable to ensure the safety of the child transported in the stroller. Conventionally, hoops are used, which are placed in front of the child, substantially in a horizontal plane. The child no longer risks falling from the stroller, and is protected from certain impacts.
Tant que les deux côtés latéraux du châssis de la poussette sont conçus de façon que leur écartement reste fixe pendant le pliage et le dépliage, la présence d'un tel arceau de maintien ne pose pas de problème particulier. En revanche, si le pliage conduit à un rapprochement de ces deux éléments de châssis, il faut que la largeur de l'arceau puisse également être modifiée. On a ainsi conçu des arceaux de maintien pliants, une articulation étant prévue au milieu de l'arceau. Toutefois, ces arceaux de maintien connus s'avèrent peu pratiques, car leur mise en place (dépliage) et leur pliage nécessitent des manipulations spécifiques, venant se rajouter aux manipulations propres à commander le pliage ou le dépliage de la poussette. Par ailleurs, les techniques connues s'avèrent difficilement compatibles avec les poussettes permettant d'obtenir, en position pliée, un encombrement très réduit. 2-3- sécurité anti-repliageAs long as the two lateral sides of the stroller chassis are designed so that their spacing remains fixed during folding and unfolding, the presence of such a support arch does not pose any particular problem. On the other hand, if the folding leads to a bringing together of these two chassis elements, the width of the arch must also be able to be modified. Folding hoops have thus been designed, a hinge being provided in the middle of the hoop. However, these known retaining bars prove to be impractical, since their installation (unfolding) and their folding require specific manipulations, being added to the manipulations suitable for controlling the folding or unfolding of the stroller. In addition, the known techniques prove to be difficult to compatible with strollers making it possible to obtain, in the folded position, a very small size. 2-3- anti-folding safety
Dans le document de brevet FR- 2 692 162 est par ailleurs décrite une technique avantageuse de verrouillage de la poussette en position déployée et de déverrouillage pour permettre le retour à la position pliée. Selon cette technique, il suffit de faire pivoter une portion du guidon de la poussette, puis de pousser sur le guidon pour que la poussette se replie complètement.In the patent document FR-2 692 162 is also described an advantageous technique of locking the stroller in the deployed position and unlocking to allow return to the folded position. According to this technique, simply rotate a portion of the handlebar of the stroller, then push on the handlebars so that the stroller folds completely.
Cette technique de verrouillage est particulièrement ergonomique et simple à utiliser. Elle introduit cependant un risque de manipulation involontaire du mécanisme de déverrouillage, entraînant un repliage intempestif de la poussette, alors qu'un enfant est encore présent dans le hamac.This locking technique is particularly ergonomic and simple to use. However, it introduces a risk of unintentional manipulation of the unlocking mechanism, causing inadvertent folding of the stroller, while a child is still present in the hammock.
Cette situation peut d'ailleurs, plus généralement, se produire avec tout système de verrouillage. Selon les cas, elle peut être le fait de la personne qui pousse la poussette, momentanément distraite ou qui agit par exemple sur l'inclinaison de la poussette, ou d'un enfant (porté dans la poussette ou monté à l'arrière de celle-ci). Un tel repliage intempestif peut également être dû au fait que, suite à un problème quelconque, le système de verrouillage saute ou lâche.This situation can moreover generally occur with any locking system. Depending on the case, it can be caused by the person pushing the stroller, temporarily distracted or who acts for example on the inclination of the stroller, or by a child (carried in the stroller or mounted on the back of the stroller). -this). Such untimely folding can also be due to the fact that, following any problem, the locking system jumps or is loose.
Dans tous les cas, on comprend clairement que les risques pour l'enfant présent dans la nacelle sont importants. Il risque de se retrouver écraser entre les éléments du châssis, et de se pincer ou de se coincer les mains ou les membres inférieurs. Bien qu'un tel repliage intempestif soit rare dans la pratique, les risques existent et peuvent, dans certains cas exceptionnels, conduire à des traumatismes graves. 3- Objectifs de l'invention L'invention a notamment pour objectif d'apporter une nouvelle solution à ces problèmes, et de pallier les différents inconvénients de l'état de l'art. 3-1- pliage compactIn all cases, it is clearly understood that the risks for the child present in the basket are significant. It may end up being crushed between the elements of the chassis, and pinching or jamming your hands or lower limbs. Although such untimely folding is rare in practice, the risks exist and can, in exceptional cases, lead to serious trauma. 3- Objectives of the invention The object of the invention is in particular to provide a new solution to these problems, and to overcome the various drawbacks of the state of the art. 3-1- compact folding
Plus précisément, un objectif de l'invention est de fournir une poussette pliante dont l'encombrement soit inférieur, en position pliée, à celui des poussettes connues. En particulier, l'invention a pour objectif d'améliorer l'efficacité, en terme de réduction de l'encombrement, de la poussette décrite dans le document FR-2 693 162.More specifically, an objective of the invention is to provide a folding stroller whose size is smaller, in the folded position, than that of known strollers. In particular, the invention aims to improve efficiency, in terms of reduction of the size of the stroller described in document FR-2 693 162.
L'invention a également pour objectif de fournir une telle poussette, qui soit simple à manipuler, les opérations de pliage et de dépliage se faisant en une seule opération. Encore un autre objectif de l'invention est de fournir une telle poussette, dont la construction est simplifiée, et dont la complexité est réduite. En d'autres termes, un objectif de l'invention est d'abaisser le coût de revient d'une telle poussette.The invention also aims to provide such a stroller, which is simple to handle, the folding and unfolding operations being carried out in a single operation. Yet another object of the invention is to provide such a stroller, the construction of which is simplified, and the complexity of which is reduced. In other words, an objective of the invention is to lower the cost price of such a stroller.
Un autre objectif de l'invention est de fournir une telle poussette, présentant au moins les mêmes qualités que les poussettes connues, en termes de sécurité, de confort, de réglage,...Another objective of the invention is to provide such a stroller, having at least the same qualities as known strollers, in terms of safety, comfort, adjustment, etc.
3-2- arceau de maintien3-2- roll bar
Un autre objectif de l'invention est de fournir une poussette pliante dont le pliage et le dépliage se font de façon directe et simple, en une seule opération, y compris pour l'arceau de maintien. En d'autres termes, un objectif de l'invention est de fournir une telle poussette équipée d'un arceau de maintien qui : se mette automatiquement en position stable de maintien, lorsque la poussette est déployée ; se plie automatiquement, lors du pliage, sans nuire à la compacité de l'ensemble. En effet, un objectif de l'invention est également de fournir une telle poussette pliante qui soit d'un encombrement très réduit, en position pliée, malgré la présence d'un arceau de maintien.Another object of the invention is to provide a folding stroller whose folding and unfolding is done in a direct and simple manner, in a single operation, including for the retaining arch. In other words, an objective of the invention is to provide such a stroller equipped with a support arch which: automatically moves into a stable position for maintenance, when the stroller is deployed; folds automatically when folded, without compromising the compactness of the assembly. Indeed, an objective of the invention is also to provide such a folding stroller which is very compact, in the folded position, despite the presence of a support arch.
L'invention a également pour objectif de fournir une telle poussette pliante, qui soit d'un coût de revient réduit, notamment en ce qui concerne l'arceau de maintien. 3-3- sécurité anti-repliaseThe invention also aims to provide such a folding stroller, which is a reduced cost, especially with regard to the support arch. 3-3- anti-aliasing security
Un autre objectif de l'invention est de fournir une poussette pour enfant qui maintienne ce dernier en sécurité, en cas de déverrouillage intempestif du dispositif du maintien de la poussette en position déployée.Another object of the invention is to provide a stroller for children which keeps the latter safe, in the event of untimely unlocking of the device for holding the stroller in the deployed position.
Un autre objectif de l'invention est encore de fournir une telle poussette, dont le dispositif de sécurité n'influe pas sur le fonctionnement normal du pliage et du dépliage. En d'autres termes, l'invention a pour objectif de fournir un dispositif de sécurité dont le fonctionnement est transparent pour l'utilisateur.Another object of the invention is also to provide such a stroller, the safety device of which does not influence the normal operation of folding and unfolding. In other words, the invention aims to provide a security device whose operation is transparent to the user.
En particulier, un objectif de l'invention est de fournir un tel dispositif qui ne complexifie pas le dépliage, qui ne risque pas d'introduire de frictions, voir de blocage en cours de pliage ou de dépliage, et qui ne nécessite aucun manipulation supplémentaire pour l'utilisateur.In particular, an objective of the invention is to provide such a device which does not make unfolding more complex, which does not risk introducing friction, or even blocking during folding or unfolding, and which does not require any additional manipulation. for the user.
Encore un autre objectif de l'invention est de fournir un tel dispositif de sécurité, qui n'influe pas sur l'encombrement de la poussette, en position pliée.Yet another objective of the invention is to provide such a safety device, which does not affect the size of the stroller, in the folded position.
L'invention a également pour objectif de fournir un tel dispositif qui soit peu coûteux à fabriquer, et simple à fabriquer, à monter et à mettre en oeuvre.The invention also aims to provide such a device which is inexpensive to manufacture, and simple to manufacture, to assemble and to implement.
4- Caractéristiques principales de l'invention 4-1- pliage compact4- Main characteristics of the invention 4-1- compact folding
Ces objectifs, ainsi que d'autres qui apparaîtront par la suite, sont atteints selon l'invention à l'aide d'une poussette pliante, du type présentant deux bras-poussoirs susceptibles de coulisser sensiblement parallèlement à des piètements du châssis de ladite poussette, entre deux positions extrêmes : une position déployée, dans laquelle lesdits bras-poussoirs sont déployés, ladite poussette développant un hamac prêt à recevoir un enfant ; et une position pliée, dans laquelle lesdits bras-poussoirs sont au moins partiellement ramenés le long desdits piètements, de façon à réduire l'encombrement de ladite poussette, chacun desdits bras-poussoirs portant au moins un élément de support dudit hamac, solidaire d'une partie supérieure dudit hamac et mobile en translation par rapport audit bras-poussoir, sur une portion pré-déterminée de ce dernier. Ainsi, selon l'invention, il n'est plus prévu d'éléments indépendants pour maintenir le hamac, qui devaient être montés sur le châssis, ce qui rajoutaient des éléments limitant les possibilités de pliage. La technique de l'invention repose sur une technique nouvelle, et non évidente, consistant à solidariser le hamac directement aux bras-poussoirs, par l'intermédiaire d'éléments mobiles en translation. Cette approche n'est pas évidente, notamment du fait que l'homme du métier considérait qu'il était nécessaire, pour permettre un repliage optimal, de laisser complètement libre les bras- poussoirs.These objectives, as well as others which will appear subsequently, are achieved according to the invention using a folding stroller, of the type having two push-arms capable of sliding substantially parallel to the legs of the chassis of said stroller , between two extreme positions: a deployed position, in which said push arms are deployed, said stroller developing a hammock ready to receive a child; and a folded position, in which said push arms are at least partially brought back along said legs, so as to reduce the size of said stroller, each of said push arms carrying at least one support element of said hammock, integral with an upper part of said hammock and movable in translation relative to said push arm, on a predetermined portion of the latter. Thus, according to the invention, there are no longer any independent elements for holding the hammock, which had to be mounted on the frame, which added elements limiting the possibilities of folding. The technique of the invention is based on a new technique, and not obvious, consisting in securing the hammock directly to the push arms, by means of elements movable in translation. This approach is not obvious, in particular because the person skilled in the art considered that he was necessary, to allow optimal folding, to leave the push arms completely free.
La technique de l'invention permet d'optimiser le compactage, en position pliée, tout en limitant le nombre de pièces nécessaires, et la complexité de ces dernières. La manipulation de la poussette reste malgré tout très simple.The technique of the invention makes it possible to optimize compaction, in the folded position, while limiting the number of parts required, and the complexity of the latter. The handling of the stroller nevertheless remains very simple.
De façon avantageuse, lesdits éléments de support sont des coulisseaux montés coulissant sur lesdits bras-poussoirs, lesdits coulisseaux étant solidarisés audit hamac.Advantageously, said support elements are slides mounted to slide on said push arms, said slides being secured to said hammock.
D'autres techniques peuvent bien sûr être envisagées, tel qu'un élément mobile dans une rainure réalisée sur le bras-poussoir. Selon un mode de réalisation préférentiel de l'invention, la partie supérieure dudit hamac est solidarisée auxdits coulisseaux par l'intermédiaire d'un lien passant par lesdits coulisseaux et circulant à l'arrière dudit hamac.Other techniques can of course be envisaged, such as a movable element in a groove made on the pusher arm. According to a preferred embodiment of the invention, the upper part of said hammock is secured to said slides by means of a link passing through said slides and circulating at the rear of said hammock.
Dans ce cas, la longueur dudit lien est avantageusement réglable, de façon à permettre la modification de l'inclinaison dudit hamac. Avantageusement, la surface interne des coulisseaux présente un élément de guidage coopérant avec un bossage (ou une rainure) correspondant pratiqué sur ladite portion pré-déterminée dudit bras-poussoir.In this case, the length of said link is advantageously adjustable, so as to allow the inclination of said hammock to be modified. Advantageously, the internal surface of the slides has a guide element cooperating with a corresponding boss (or groove) formed on said predetermined portion of said push arm.
De cette façon, le guidage et le positionnement du coulisseau est simple et précis.In this way, the guidance and positioning of the slide is simple and precise.
D'autres méthodes sont envisageables, tel que l'usage de butée. II est à noter que ce positionnement est surtout nécessaire en position déployée.Other methods are possible, such as the use of a stop. It should be noted that this positioning is especially necessary in the deployed position.
En position pliée, le coulisseau pourra venir en contact avec la poignée du bras-poussoir, pour optimiser le compactage.In the folded position, the slide can come into contact with the handle of the pusher arm, to optimize compaction.
Selon un mode de réalisation avantageux de l'invention, ledit hamac comprend deux tringles latérales de guidage, flottantes, s' étendant sensiblement sur toute la hauteur dudit hamac, la partie inférieure de chacune desdites tringles étant montée coulissante sur un élément de guidage solidaire de l'extrémité inférieure du bras-poussoir correspondant. On notera que ces tringles n'ont pas la fonction de support du hamac, contrairement aux montants utilisés selon l'art antérieur. Comme on l'a déjà mentionné, cette fonction est assurée par des éléments de support, tels que des coulisseaux. Ces tringles sont donc des éléments flottants, d'un faible diamètre, et non des montants. Avantageusement, lesdits éléments de support mobiles peuvent comprendre quatre coulisseaux montés sur lesdits bras-poussoirs, deux coulisseaux supérieurs solidaires de la partie supérieure dudit hamac, et deux coulisseaux inférieurs, solidaires de la partie inférieure dudit hamac. Selon une caractéristique particulière de l'invention, on peut prévoir qu'au moins un desdits éléments de support mobiles comprend des moyens de fixation d'au moins un élément optionnel, tel qu'un pare- soleil ou une sangle de portage. 4-2- arceau de maintienAccording to an advantageous embodiment of the invention, said hammock comprises two lateral guide rods, floating, extending substantially over the entire height of said hammock, the lower part of each of said rods being slidably mounted on a guide element integral with the lower end of the corresponding push arm. Note that these rods do not have the function of supporting the hammock, unlike the amounts used according to the prior art. As already mentioned, this function is provided by support elements, such as slides. These rods are therefore floating elements, of a small diameter, and not uprights. Advantageously, said movable support elements may include four slides mounted on said push arms, two upper slides secured to the upper part of said hammock, and two lower slides, secured to the lower part of said hammock. According to a particular characteristic of the invention, it can be provided that at least one of said mobile support elements comprises means for fixing at least one optional element, such as a sun visor or a carrying strap. 4-2- roll bar
Selon l'invention, la poussette pliante est du type présentant deux bras-poussoirs susceptibles de coulisser sensiblement parallèlement à des piètements de châssis de ladite poussette, entre deux positions extrêmes : une position déployée, dans laquelle lesdits bras-poussoirs sont déployés, ladite poussette développant un hamac prêt à recevoir un enfant ; et une position pliée, dans laquelle lesdits bras-poussoirs sont au moins partiellement ramenés le long desdits piètements, de façon à réduire l'encombrement de ladite poussette. Elle comprend un arceau de maintien mobile de façon qu'il soit : placé sensiblement dans un plan défini par lesdits bras-poussoirs, dans ladite position pliée, et - maintenu dans un plan sensiblement horizontal, de façon à assurer la sécurité d'un enfant, dans ladite position déployée, des moyens de guidage et de maintien pilotés par le déplacement d'au moins un desdits bras-poussoirs assurant le positionnement dudit arceau de maintien.According to the invention, the folding stroller is of the type having two pusher arms capable of sliding substantially parallel to the chassis legs of said stroller, between two extreme positions: a deployed position, in which said pusher arms are deployed, said stroller developing a hammock ready to receive a child; and a folded position, in which said push arms are at least partially brought back along said legs, so as to reduce the size of said stroller. It comprises a movable support hoop so that it is: placed substantially in a plane defined by said push arms, in said folded position, and - maintained in a substantially horizontal plane, so as to ensure the safety of a child , in said deployed position, guiding and holding means controlled by the movement of at least one of said push arms ensuring the positioning of said holding hoop.
Ainsi, l'arceau de maintien est mis en place automatiquement, lors du dépliage, sans qu'aucune manipulation spécifique ni aucun verrouillage ne soit nécessaire.Thus, the retaining arch is put in place automatically, during unfolding, without any specific manipulation or locking being necessary.
Selon un mode de réalisation avantageux de l'invention, lesdits moyens de guidage et de maintien comprennent au moins une biellette dont une première extrémité est solidaire dudit arceau de maintien, et dont la seconde extrémité est entraînée par le déplacement d'un desdits bras-poussoirs. Comme on le verra par la suite, cette solution est particulièrement simple, et donc peu coûteuse à mettre en oeuvre.According to an advantageous embodiment of the invention, said guiding and holding means comprise at least one link, a first end of which is integral with said retaining hoop, and the second end of which is driven by the displacement of one of said arms- pushers. As we will see later, this solution is particularly simple, and therefore inexpensive to implement.
Dans ce cas, pour des raisons de symétrie du mouvements, on prévoit préféren tellement deux biellettes, coopérant respectivement avec chacun desdits deux bras-poussoirs. De façon avantageuse, ladite seconde extrémité est solidarisée, libre en rotation, à un coulisseau circulant sur la partie inférieure d'un desdits bras-poussoirs.In this case, for reasons of symmetry of the movements, two rods are preferably provided, cooperating respectively with each of said two push arms. Advantageously, said second end is secured, free in rotation, to a slide circulating on the lower part of one of said push arms.
Le mouvement de ce coulisseau le long du bras-poussoir entraine la mise en place et le pliage de l'arceau.The movement of this slide along the pusher arm causes the roll bar to be put in place and folded.
Ledit coulisseau peut par exemple être entraîné par un élément de terminaison, fixé à l'extrémité inférieure dudit bras-poussoir.Said slide can for example be driven by a termination element, fixed to the lower end of said pusher arm.
De façon préférentielle, ladite seconde extrémité est décalée sous un plan défini par lesdits bras-poussoirs, de façon à faciliter les déplacements de l'arceau de maintien.Preferably, said second end is offset under a plane defined by said push arms, so as to facilitate the movements of the retaining arch.
Avantageusement, ledit coulisseau coulisse simultanément sur ledit bras-poussoir et sur le piètement correspondant. Selon un mode de réalisation avantageux, ledit arceau de maintien comprend deux éléments d'accrochage montés chacun pivotant respectivement sur un manchon dans lequel est introduit l'extrémité d'un desdits piètements, et dans lequel coulisse le bras- poussoir correspondant.Advantageously, said slide slides simultaneously on said pusher arm and on the corresponding base. According to an advantageous embodiment, said retaining arch comprises two hooking elements each mounted to pivot respectively on a sleeve into which the end of one of said legs is introduced, and in which the corresponding push arm slides.
Ledit arceau de maintien est par exemple formé de deux demi-arceaux articulés entre eux. Il peut comprendre un élément d'articulation présentant deux axes de rotation associé respectivement auxdits demi-arceau. 4-3- sécurité anti-repliageSaid support hoop is for example formed by two half-hoops hinged together. It may include an articulation element having two axes of rotation associated respectively with said half-arch. 4-3- anti-folding safety
Selon un autre aspect de l'invention, la poussette pliante, toujours du type présentant deux bras-poussoirs susceptibles de coulisser sensiblement parallèlement à des piètements de châssis de ladite poussette, entre deux positions extrêmes : une position déployée, dans laquelle lesdits bras-poussoirs sont déployés, ladite poussette développant un hamac prêt à recevoir un enfant ; et une position pliée, dans laquelle lesdits bras-poussoirs sont au moins partiellement ramenés le long desdits piètements, de façon à réduire l'encombrement de ladite poussette, comprend des moyens de sécurité empêchant le repliement complet de ladite poussette lorsqu'un enfant est présent dans ledit hamac, comprenant au moins deux éléments de blocage montés respectivement sur un des bras-poussoirs et sur le piètement correspondant, et pouvant prendre au moins deux positions : - une position de sécurité, dans laquelle lesdits éléments de blocage coopèrent pour empêcher, ou limiter sur une portion prédéterminée, le coulissement dudit bras-poussoir le long dudit piètement, lorsqu'un enfant est présent dans ledit hamac ; une position de libération, dans laquelle lesdits éléments n'interagissent pas, permettant le coulissement dudit bras-poussoir le long dudit piètement, lorsqu'il n'y a pas d'enfant dans ledit hamac. En d'autres termes, lorsque enfant est présent dans le hamac, le repliage de la poussette est impossible, même si un déverrouillage intempestif des moyens de fixation de celle-ci est effectué. La sécurité de l'enfant est donc assuré simplement et automatiquement, sans aucune manipulation supplémentaire par rapport à l'art antérieur.According to another aspect of the invention, the folding stroller, always of the type having two push arms capable of sliding substantially parallel to the chassis legs of said stroller, between two extreme positions: a deployed position, in which said push arms are deployed, said stroller developing a hammock ready to receive a child; and a folded position, in which said push arms are at least partially brought back along said legs, so as to reduce the size of said stroller, comprises safety means preventing the complete folding of said stroller when a child is present in said hammock, comprising at least two blocking elements mounted respectively on one of the push arms and on the corresponding base, and being able to take at least two positions : - a safety position, in which said blocking elements cooperate to prevent, or limit over a predetermined portion, the sliding of said pusher arm along said base, when a child is present in said hammock; a release position, in which said elements do not interact, allowing the sliding of said pusher arm along said base, when there is no child in said hammock. In other words, when a child is present in the hammock, folding the stroller is impossible, even if an untimely unlocking of the fastening means is carried out. Child safety is therefore ensured simply and automatically, without any additional manipulation compared to the prior art.
Avantageusement, la présence d'un enfant est détectée par le poids appliqué par ce dernier sur le hamac.Advantageously, the presence of a child is detected by the weight applied by the latter to the hammock.
Selon un mode de réalisation préférentiel de l'invention, lesdits éléments de blocage comprennent : - un élément fixe, monté sur le piètement ou sur le bras-poussoir respectivement ; un élément mobile, monté sur le bras-poussoir ou sur le piètement respectivement, et pouvant pivoter autour de l'axe défini pas ledit bras- poussoir ou ledit piètement. Selon le placement de l'élément mobile, la poussette se trouve soit en position de sécurité, soit en position de libération.According to a preferred embodiment of the invention, said blocking elements comprise: - a fixed element, mounted on the base or on the push arm respectively; a movable element, mounted on the push arm or on the base respectively, and which can pivot around the axis defined by said push arm or said base. Depending on the placement of the mobile element, the stroller is either in the safety position or in the release position.
De façon avantageuse, ledit élément mobile peut ainsi comprendre une butée prenant appui contre ledit élément fixe, en position de sécurité, et étant décalée par rapport audit élément fixe, de façon à permettre le repliage, en position de libération. Selon un mode de réalisation de l'invention, ledit élément mobile est monté à l'extrémité d'un desdits bras-poussoirs. Il pourrait également être monté sur le piètement. Avantageusement, ledit élément mobile comprend des moyens de rappel, tendant à ramener ledit élément mobile en position de libération. La force de rappel est telle qu'elle ne peut contrecarrer la force appliquée sur le hamac par le poids de l'enfant. Préférentiellement, ledit élément mobile présente une ouverture ou une encoche coopérant avec une tringle de support et de guidage dudit hamac. Le coulissement de cette tringle permet d'optimiser l'encombrement et le positionnement du hamac.Advantageously, said movable element can thus comprise a stop bearing against said fixed element, in the safety position, and being offset with respect to said fixed element, so as to allow folding, in the release position. According to one embodiment of the invention, said movable element is mounted at the end of one of said push arms. It could also be mounted on the base. Advantageously, said mobile element comprises return means, tending to return said mobile element to the release position. The restoring force is such that it cannot counteract the force applied to the hammock by the weight of the child. Preferably, said movable element has an opening or a notch cooperating with a support and guide rod for said hammock. The sliding of this rod optimizes the size and positioning of the hammock.
Selon un mode de réalisation avantageux, ladite position de sécurité correspond à une position de pliage intermédiaire de ladite poussette, un jeu étant prévu de façon à permettre un déverrouillage et un verrouillage de la poussette en positon déployée.According to an advantageous embodiment, said safety position corresponds to an intermediate folding position of said stroller, a clearance being provided so as to allow the stroller to be unlocked and locked in the deployed position.
Cela permet à l'utilisateur de visualiser la tentative de repliage, et donc d'attirer son attention. Cependant, on peut également prévoir que les moyens de blocage ne permettent aucun jeu, la poussette restant en position déployée.This allows the user to visualize the folding attempt, and therefore to draw his attention. However, it can also be provided that the locking means allow no play, the stroller remaining in the deployed position.
De façon avantageuse, ledit élément fixe est un plot d'arrêt placé sur un desdits piètement de façon à permettre un coulissement du bras-poussoir correspondant sur une portion prédéterminée et limitée dudit piètement.Advantageously, said fixed element is a stop stud placed on one of said legs so as to allow the corresponding push arm to slide over a predetermined and limited portion of said legs.
L'invention concerne également le dispositif de sécurité anti-repliement pour une telle poussette, en tant que tel. 5- Liste des figures D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description suivante d'un mode de réalisation préférentiel de l'invention, donné à titre de simple exemple illustratif et non limitatif, et des dessins annexés, parmi lesquels : la figure 1 est une vue en élévation d'une poussette selon l'invention, en position déployée ; la figure 2 est une vue arrière de la poussette de la figure 1 ; la figure 3 est une vue en élévation de la poussette des figures 1 et 2 en position pliée ; les figures 4a et 4b présentent, vu de dessus et vu de côté respectivement, le coulisseau supérieur de la poussette des figures 1 à 3 ; les figures 5a et 5b présentent, vu de dessus et vu de côté respectivement l'élément inférieur de terminaison inférieure du bras-poussoir de la poussette des figures 1 à 3 ; les figures 6a et 6b présentent, vu de dessus et vu de côté respectivement, l'élément de maintien de la tringle de guidage du hamac de la poussette des figures 1 à 3 ; la figure 7 est une vue en élévation, similaire à la figure 1, la poussette étant équipée d'un arceau de maintien ; la figure 8 illustre les moyens de mise en place et de maintien de l'arceau de maintien de la poussette de la figure 7, en position déployée ; la figure 9 illustre les moyens de mise en place et de maintien de l'arceau de maintien de la poussette de la figure 7, en position pliée ; la figure 10 présente l'arceau de maintien de la poussette en position déployée, en vue de dessus ; - la figure 11 présente l'arceau de maintien de la figure 10, en position pliée; la figure 12 est une vue partielle agrandie des éléments formant le dispositif de sécurité de l'invention ; les figures 13A et 13B présentent l'élément mobile du dispositif de sécurité de la figure 12 vu de dessus, en positions de libération et de sécurité respectivement.The invention also relates to the anti-folding safety device for such a stroller, as such. 5- List of Figures Other characteristics and advantages of the invention will appear more clearly on reading the following description of a preferred embodiment of the invention, given by way of simple illustrative and nonlimiting example, and attached drawings, among which: FIG. 1 is an elevation view of a stroller according to the invention, in the deployed position; Figure 2 is a rear view of the stroller of Figure 1; Figure 3 is an elevational view of the stroller of Figures 1 and 2 in the folded position; Figures 4a and 4b show, seen from above and seen from the side respectively, the upper slide of the stroller of Figures 1 to 3; FIGS. 5a and 5b show, seen from above and seen from the side respectively, the lower lower termination element of the push arm of the stroller of FIGS. 1 to 3; Figures 6a and 6b show, seen from above and seen from the side respectively, the holding element of the guide rod of the hammock of the stroller of Figures 1 to 3; Figure 7 is an elevational view, similar to Figure 1, the stroller being equipped with a support arch; FIG. 8 illustrates the means for positioning and maintaining the hoop for holding the stroller of FIG. 7, in the deployed position; FIG. 9 illustrates the means for positioning and maintaining the hoop for holding the stroller of FIG. 7, in the folded position; Figure 10 shows the stroller holding arch in the deployed position, seen from above; - Figure 11 shows the retaining arch of Figure 10, in the folded position; Figure 12 is an enlarged partial view of the elements forming the safety device of the invention; Figures 13A and 13B show the movable member of the safety device of Figure 12 seen from above, in release and safety positions respectively.

Le mode de réalisation préférentiel décrit ci-dessous repose sur la mise en oeuvre d'un châssis pliant similaire à celui décrit dans le document de brevet FR-2 693 162 déjà mentionné.The preferred embodiment described below is based on the implementation of a folding frame similar to that described in the patent document FR-2 693 162 already mentioned.
On ne décrit donc pas par la suite en détail le principe du fonctionnement de ce châssis. On se reportera, en cas de besoin, au document précité.The principle of operation of this chassis is therefore not described in detail below. Reference will be made, if necessary, to the aforementioned document.
On rappelle cependant que, ainsi que cela est illustré sur les figures 1 à 3, la poussette selon l'invention présente deux ensembles latéraux de châssis la et lb (figure 2). On décrit, en relation avec les figures 1 et 3, l'ensemble latéral indicé a. L'autre ensemble latéral de châssis comprend les mêmes éléments affectés des mêmes références numériques, avec un indice b.It is recalled, however, that, as illustrated in FIGS. 1 to 3, the stroller according to the invention has two lateral chassis assemblies 1a and 1b (FIG. 2). We describe, in relation to Figures 1 and 3, the side assembly indexed a. The other chassis side assembly comprises the same elements with the same reference numbers, with an index b.
En se reportant à la figure 1, on note que l'ensemble latéral de châssis comprend un piètement avant 2a et un piètement arrière 3a, portant à leurs extrémités inférieures une roue, ou un bloc de roues, 5a et 6a respectivement. Ces roues ou ensembles de roues peuvent classiquement recevoir des suspensions, des moyens de freinage, et éventuellement être montées pivotantes.Referring to Figure 1, it is noted that the lateral chassis assembly comprises a front base 2a and a rear base 3a, carrying at their lower ends a wheel, or a wheel block, 5a and 6a respectively. These wheels or wheel assemblies can conventionally receive suspensions, braking means, and possibly be pivotally mounted.
L'ensemble latéral de châssis présente encore un bras-poussoir 8a, se terminant à son extrémité supérieure par une zone de préhension coudée 9a. Comme cela apparaît en figure 2, les deux zones de préhension 9a, 9b (poignées) peuvent être reliées entre elles par un élément de liaison, de façon à former un guidon 10. Avantageusement, ce guidon peut également être utilisé comme moyen de verrouillage et de commande du pliage et/ou du dépliage de la poussette, par exemple selon le principe décrit dans le document FR -The lateral chassis assembly also has a push arm 8a, ending at its upper end with a bent gripping zone 9a. As shown in FIG. 2, the two gripping zones 9a, 9b (handles) can be connected together by a connecting element, so as to form a handlebar 10. Advantageously, this handlebar can also be used as a locking means and for controlling the folding and / or unfolding of the stroller, for example according to the principle described in the document FR -
2 693 162. Ainsi que cela apparaît sur la figure 2, un châssis 11 en forme d'X articulé, formé de deux croisillons 12 et 13, relie les deux piètements arrière 3a et 3b.2,693,162. As can be seen in FIG. 2, an articulated X-shaped frame 11, formed of two cross-pieces 12 and 13, connects the two rear legs 3a and 3b.
Une bielle de liaison 21a est également prévue. Elle est articulée d'une part à son extrémité supérieure sur un axe solidaire de l' extrémité inférieure du bras-poussoir 8a, et d'autre part sur un axe solidaire de la partie inférieure du piètement arrière 3a. Plus précisément, la partie supérieure de la biellette 21a est montée sur un élément de terminaison 24a, fixé à l'extrémité inférieure du bras-poussoir 8a. Cet élément est illustré sur les figures 5a et 5b.A connecting rod 21a is also provided. It is articulated on the one hand at its upper end on an axis integral with the lower end of the pusher arm 8a, and on the other hand on an axis integral with the lower part of the rear base 3a. More specifically, the upper part of the link 21a is mounted on a termination element 24a, fixed to the lower end of the push arm 8a. This element is illustrated in Figures 5a and 5b.
Ces différents éléments sont par exemple réalisés sous la forme de tubes métalliques et/ou de tringles en fer plat. Un manchon de liaison 18a solidarise les piètements avant 2a et arrière 3a et le bras-poussoir 8a. L'extrémité supérieure du piètement avant 2a est maintenue de façon fixe, par un axe traversant 19a. L'extrémité supérieure du piètement arrière 3a est montée pivotante sur un axe 20a, de façon que lors du pliage la roue arrière puisse se rapprocher de la roue avant. Le bras-poussoir 8a peut coulisser librement dans ce manchon de liaison, parallèlement au piètement avant 2a. Selon l'invention, le hamac, ou nacelle, 25 est solidarisé, à sa partie supérieure, à un coulisseau 30a qui peut coulisser librement le long de la partie supérieure du bras- poussoir 8a, sur une partie prédéterminée de celui-ci s'étendant de la poignée 9a jusqu'à une position inférieure, permettant le transport d'un enfant. La zone de coulissement est définie sur le bras-poussoir, par exemple par un bossage en creux, ou une rainure. La forme intérieure du coulisseau 30a est définie de façon à coopérer avec ce bossage 31a.These various elements are for example made in the form of metal tubes and / or flat iron rods. A connecting sleeve 18a secures the front legs 2a and rear 3a and the pusher arm 8a. The upper end of the front base 2a is fixedly held by a through axis 19a. The upper end of the rear base 3a is pivotally mounted on an axis 20a, so that during folding the rear wheel can approach the front wheel. The push arm 8a can slide freely in this connecting sleeve, parallel to the front base 2a. According to the invention, the hammock, or nacelle, 25 is secured, at its upper part, to a slide 30a which can slide freely along the upper part of the push arm 8a, on a predetermined part thereof. extending from the handle 9a to a lower position, allowing the transport of a child. The sliding zone is defined on the pusher arm, for example by a hollow boss, or a groove. The internal shape of the slide 30a is defined so as to cooperate with this boss 31a.
La partie supérieure du hamac est par exemple liée au coulisseau 30a par un lien 32. Avantageusement, ce lien 32 passe par les deux coulisseaux 30a et 30b et circule en boucle à l'arrière du hamac. La longueur de ce lien est préférentiellement réglable, de façon à permettre le réglage de l'inclinaison du hamac.The upper part of the hammock is for example linked to the slider 30a by a link 32. Advantageously, this link 32 passes through the two sliders 30a and 30b and circulates in a loop behind the hammock. The length of this link is preferably adjustable, so as to allow the tilting of the hammock to be adjusted.
Le hamac 25 présente deux volets 33a et 33b, qui viennent recouvrir partiellement le bras-poussoir et le coulisseau (ces rabats sont présentés volontairement rabaissés sur la figure 2, de façon à laisser apparents les coulisseaux). Le lien 32 de maintien et de réglage de l'inclinaison peut être fixé à l'extrémité de ces rabats.The hammock 25 has two flaps 33a and 33b, which partially cover the pusher arm and the slide (these flaps are voluntarily shown lowered in Figure 2, so as to leave the slides visible). The link 32 for maintaining and adjusting the inclination can be fixed to the end of these flaps.
Deux tringles 36a et 36b sensiblement parallèles aux bras-poussoirs et aux piètements avant s'étendent le long du hamac. Elles sont maintenues par leur extrémité inférieure et supérieure par des logements prévus à cet effet dans le hamac. Un passant 35a solidarise le hamac à la tringle, sensiblement au niveau de l'assise. Ces tringles permettent notamment de faciliter le guidage du hamac, lors du pliage et du dépliage. Pour cela, chaque tringle est montée coulissante sur un élément de maintien 34a solidaire de l'extrémité du bras-poussoir, détaillée par la suite.Two rods 36a and 36b substantially parallel to the push arms and the front legs extend along the hammock. They are held by their lower and upper ends by housings provided for this purpose in the hammock. A passer-by 35a secures the hammock to the rod, substantially at the level of the seat. These rods allow in particular to facilitate the guiding of the hammock, during folding and unfolding. For this, each rod is slidably mounted on a holding element 34a secured to the end of the pusher arm, detailed below.
Les figures 4a et 4b illustrent un mode de réalisation du coulisseau supérieur selon l'invention. La section de la partie intérieure 41 présente une portion plane 42. Cette portion plane est conçue de façon à coopérer avec un bossage pratiqué sur le bras- poussoir 8, de façon que le coulissement ne soit possible que sur la partie où le bossage est réalisé, et non sur la partie où le bras-poussoir présente une section parfaitement circulaire. Avantageusement, une pièce , du type "clip-verrou" est prévue pour l'enfilage. Ainsi, la zone de coulissement du coulisseau est parfaitement définie et limitée. D'autres techniques sont bien sûr envisageables pour limiter cette zone de coulissement, telle que la réalisation d'une rainure dans le bras-poussoir, coopérant avec un pion ménagé dans le coulisseau, ou encore la mise en place d'une butée à l'emplacement idoine sur le bras-poussoir.Figures 4a and 4b illustrate an embodiment of the upper slide according to the invention. The section of the inner part 41 has a flat portion 42. This flat portion is designed so as to cooperate with a boss formed on the pusher arm 8, so that sliding is only possible on the part where the boss is produced. , and not on the part where the push arm has a perfectly circular section. Advantageously, a part, of the "clip-lock" type, is provided for threading. Thus, the sliding zone of the slide is perfectly defined and limited. Other techniques can of course be envisaged to limit this sliding zone, such as making a groove in the pusher arm, cooperating with a pin made in the slide, or even placing a stopper in the appropriate location on the pusher arm.
Le coulisseau comprend par ailleurs deux fentes 43 et 44 dans lesquelles peut circuler le lien de maintien 32 de la partie supérieure du hamac (figures 4a et 4b).The slide also comprises two slots 43 and 44 in which the retaining link 32 of the upper part of the hammock can circulate (FIGS. 4a and 4b).
Avantageusement, le coulisseau comprend encore un élément de fixation 46, prévu pour recevoir des éléments optionnels, tels que par exemple un pare-soleil (canopy) ou une sangle de portage.Advantageously, the slide further comprises a fixing element 46, designed to receive optional elements, such as for example a sun visor (canopy) or a carrying strap.
Les figures 5a et 5b présentent l'élément de terminaison inférieur 24a du bras- poussoir. Il est prévu pour recevoir l'extrémité de ce bras-poussoir. Il présente une ouverture 51 permettant de recevoir l'axe de liaison avec la bielle 23a. Il coopère par ailleurs avec l'élément de maintien 34a de la tringle de guidage, illustré sur les figures 6a et 6b.Figures 5a and 5b show the lower termination element 24a of the pusher arm. It is intended to receive the end of this push arm. It has an opening 51 for receiving the axis of connection with the connecting rod 23a. It also cooperates with the holding element 34a of the guide rod, illustrated in FIGS. 6a and 6b.
Cet élément de maintien est solidaire en translation de l'élément 24a, mais monté libre en rotation par rapport à celui-ci. Il présente une ouverture 61 dans laquelle passe le bras-poussoir. Il est solidarisé à l'élément de terminaison 24a par un pion (par exemple une vis - non représentée) circulant dans un trou oblong 52 formé dans cet élément de terminaison 24a.This holding element is integral in translation with the element 24a, but mounted free in rotation relative to the latter. It has an opening 61 through which the pusher arm passes. It is secured to the termination element 24a by a pin (for example a screw - not shown) circulating in an oblong hole 52 formed in this termination element 24a.
Il présente par ailleurs une chape 63, percée d'une ouverture 64, recevant la tringle de guidage 36a.It also has a yoke 63, pierced with an opening 64, receiving the guide rod 36a.
Le fonctionnement de l'ensemble est donc le suivant.The operation of the assembly is therefore as follows.
En position déployée (figure 1 et 2) les coulisseaux supérieurs 30a et 30b sont entraînés vers le bas, par le poids du hamac, jusqu'à ce qu'il vienne en butée avec l'extrémité inférieure du bossage. L'élément de maintien 34a de la tringle 36a est quant à lui proche du manchon de liaison 18a.In the deployed position (FIGS. 1 and 2) the upper slides 30a and 30b are driven downwards, by the weight of the hammock, until it comes into abutment with the lower end of the boss. The holding element 34a of the rod 36a is in turn close to the connecting sleeve 18a.
Lorsque l'on met en oeuvre le pliage, par exemple par action sur le guidon 10, selon la technique décrite dans le document de brevet déjà mentionné, les bras-poussoirs coulissent dans les manchons de liaison 18a et 18b. Dans un premier temps, les coulisseaux supérieurs 30a et 30b restent dans la même position. Lorsqu'ils arrivent en contact avec le manchon de liaison, ils coulissent et remontent le long du bossage, jusqu'à venir en contact avec les poignées.When folding is carried out, for example by action on the handlebar 10, according to the technique described in the patent document already mentioned, the push arms slide in the connecting sleeves 18a and 18b. Initially, the upper slides 30a and 30b remain in the same position. When they arrive in contact with the connecting sleeve, they slide and go up along the boss, until coming into contact with the handles.
Dans le même temps, les éléments de maintien inférieurs 24a et 24b entraînent l'extrémité inférieure du hamac vers le bas, par l'intermédiaire des tringles 36a et 36b. On obtient ainsi, lorsque le pliage est complet (figure 3), un encombrement très réduit. Pour faciliter la compréhension du fonctionnement, on n'a pas représenté, sur la figure 3, le hamac 25. On comprend que celui-ci, guidé par les coulisseaux et les tringles de guidage, se plie automatiquement entre les deux éléments de châssis latéraux. Des zones de pliage sont prévues pour faciliter cette opération. Dans le mode de réalisation mettant en oeuvre le guidon décrit dans le document de brevet déjà cité, le pliage entraîne un pivotement de l'ordre de 45° des bras-poussoirs, vers l'arrière. Le même mouvement de pivotement est par conséquent appliqué aux coulisseaux 30a et 30b et aux éléments de maintien 34a et 34b, ce qui guide et facilite le pliage du hamac. Le dépliage s'obtient en tirant sur les poignées 9a et 9b (ou sur le guidon 10). Les bras-poussoirs 9a et 9b coulissent alors dans les manchons de liaison 18a et 18b, vers le haut. Les coulisseaux 30a et 30b sont ainsi entraînés le long des bossages 31a et 31b, vers le bas, sous l'effet du poids du hamac 25. Ils prennent ainsi naturellement position en butée sur le bossage 31a. Les tringles 36a et 36b entraînent dans le même temps la mise en place de la partie inférieure du hamac 25, en coulissant dans l'ouverture 64 formée dans la chape 63.At the same time, the lower holding elements 24a and 24b drive the lower end of the hammock down, by means of the rods 36a and 36b. Thus, when the folding is complete (Figure 3), a very small footprint. To facilitate the understanding of the operation, the hammock 25 has not been represented in FIG. 3. It is understood that this, guided by the slides and the guide rods, folds automatically between the two lateral chassis elements. . Folding zones are provided to facilitate this operation. In the embodiment using the handlebars described in the patent document already cited, folding results in pivoting of the order of 45 ° of the push arms, towards the rear. The same pivoting movement is therefore applied to the slides 30a and 30b and to the holding elements 34a and 34b, which guide and facilitate the folding of the hammock. Unfolding is obtained by pulling on the handles 9a and 9b (or on the handlebars 10). The push arms 9a and 9b then slide in the connecting sleeves 18a and 18b, upwards. The slides 30a and 30b are thus driven along the bosses 31a and 31b, downwards, under the effect of the weight of the hammock 25. They thus naturally take up position in abutment on the boss 31a. The rods 36a and 36b at the same time cause the lower part of the hammock 25 to be put in place, sliding in the opening 64 formed in the yoke 63.
Outre les éléments optionnels déjà mentionnés, on peut noter qu'une telle poussette peut avantageusement être équipée d'un marche-pied, d'un panier inférieur, d'un arceau de maintien,... 6-2 arceau de maintienIn addition to the optional elements already mentioned, it can be noted that such a stroller can advantageously be equipped with a step, a lower basket, a support hoop, ... 6-2 support hoop
On présente maintenant un mode de réalisation avantageux d'un tel arceau de maintien.We now present an advantageous embodiment of such a support arch.
La figure 7 illustre une poussette pliante équipée d'un arceau. On renvoie à la description des figures 1 et 2 pour les éléments identiques. Selon l'invention, la poussette comprend donc un arceau de maintien 27, maintenu en place par la biellette 28a. Le mécanisme correspondant est illustré plus en détail en figures 8 et 9.Figure 7 illustrates a folding stroller equipped with a hoop. Reference is made to the description of FIGS. 1 and 2 for the identical elements. According to the invention, the stroller therefore comprises a retaining arch 27, held in place by the link 28a. The corresponding mechanism is illustrated in more detail in Figures 8 and 9.
L'arceau de maintien 27 est monté pivotant sur un axe 29a solidaire du manchon de liaison 18a. On notera que la forme particulière de ce manchon est donné à titre de simple exemple. Elle ne dépend pas de l'arceau, mais des différents éléments qu'elle associe (piètement avant, piètement arrière et bras-poussoirs).The support arch 27 is pivotally mounted on an axis 29a integral with the connecting sleeve 18a. Note that the particular shape of this sleeve is given as a simple example. It does not depend on the arch, but on the various elements that it combines (front base, rear base and push arms).
Le bras-poussoir 8a comprend, à son extrémité inférieure, un élément de terminaison 24a. Selon l'invention il comprend de plus un coulisseau 210a, qui peut se déplacer entre cet élément de terminaison 24a et l'élément de liaison 18a. Selon un mode de réalisation avantageux, ce coulisseau 210a est double, et peut également coulisser simultanément sur le piètement 2a.The push arm 8a comprises, at its lower end, a termination element 24a. According to the invention it further comprises a slide 210a, which can move between this termination element 24a and the connecting element 18a. According to an advantageous embodiment, this slide 210a is double, and can also slide simultaneously on the base 2a.
La biellette de maintien et de guidage 28a est montée à son extrémité inférieure, sur un axe 211a, solidaire du coulisseau 210a. Cet axe 21 la est avantageusement placé sur la partie du coulisseau circulant sur le piètement 2a, de façon que l'axe 211a soit décalé par rapport au bras-poussoir 8a.The retaining and guiding link 28a is mounted at its lower end, on an axis 211a, integral with the slide 210a. This axis 21a is advantageously placed on the part of the slide circulating on the base 2a, so that the axis 211a is offset relative to the push arm 8a.
L'autre extrémité de la biellette 28a est montée sur un axe 212a d'une chape 213a portant l'arceau de maintien 27.The other end of the link 28a is mounted on an axis 212a of a yoke 213a carrying the retaining arch 27.
L'arceau de maintien 27 en lui-même est illustré en figures 10 et 11.The support arch 27 in itself is illustrated in FIGS. 10 and 11.
En position déployée (figure 10), il se présente comme un arceau de maintien classique. Il est préférentiellement recouvert de mousse de protection et/ou d'un tissu.In the deployed position (Figure 10), it looks like a conventional support arch. It is preferably covered with protective foam and / or a fabric.
Il comprend deux demi-arceaux 141a et 141b solidarisés au milieu de l'arceau par un élément de pliage 142. Il s'agit par exemple d'un mécanisme de pliage du type compas à deux axes 143a, 143b.It comprises two half-hoops 141a and 141b secured in the middle of the hoop by a folding element 142. It is for example a folding mechanism of the type compass with two axes 143a, 143b.
L'autre extrémité de chacun des demi-arceaux est montée sur un élément d'extrémité 144a, 144b, solidarisés aux éléments de liaison 18a, 18b par un axe 145a,The other end of each of the half-arches is mounted on an end element 144a, 144b, secured to the connecting elements 18a, 18b by an axis 145a,
145b, de façon à pouvoir pivoter, sous la commande des biellettes 28a, 28b.145b, so as to be able to pivot, under the control of the links 28a, 28b.
Le fonctionnement de l'arceau de maintien concernant l'invention est donc le suivant. Lorsque la poussette est en position pliée (figures 9 et 11), le bras-poussoir 8a est ramené, au travers de l'élément de liaison 18a, vers le bas, parallèlement au piètement avant 2a. Sous l'effet de la force de gravité, le coulisseau 210a, qui peut coulisser librement sur le bras-poussoir 8a et sur le piètement 2a, est entraîné vers le bas, en appui contre l'élément de terminaison 24a. La biellette 211a suit ce coulisseau 210, et entraîne donc l'arceau 27a, qui est a ramené sensiblement dans le plan défini par les deux bras- poussoirs. Dans le même temps, le pliage entraîne le rapprochement des deux éléments de châssis latéraux, et par conséquence des deux éléments de liaison 18a et 18b, ainsi que cela est illustré sur la figure 11.The operation of the retaining arch relating to the invention is therefore as follows. When the stroller is in the folded position (Figures 9 and 11), the pusher arm 8a is brought down, through the connecting element 18a, downward, parallel to the front base 2a. Under the effect of gravity, the slide 210a, which can slide freely on the push arm 8a and on the base 2a, is driven downwards, bearing against the termination element 24a. The link 211a follows this slide 210, and therefore drives the arch 27a, which is brought back substantially in the plane defined by the two push arms. At the same time, folding causes the two lateral chassis elements to come together, and consequently the two connecting elements 18a and 18b, as illustrated in FIG. 11.
Les deux demi-arceaux 141a et 141b se déplacent autour des axes 143a et 143b, de façon à pouvoir se loger entre les deux éléments de châssis latéraux sans augmenter l'encombrement résultant.The two half-arches 141a and 141b move around the axes 143a and 143b, so as to be able to be housed between the two lateral chassis elements without increasing the resulting bulk.
Lors du dépliage, le bras-poussoir 8a est ramené vers le haut. Le manchon de terminaison 24a entraîne le coulisseau 210a vers l'élément de liaison 18a, jusqu'à ce qu'il vienne en contact avec ce dernier. Le coulisseau 210a est alors immobilisé, entre l'élément de terminaison 24a et l'élément de liaison 18a . La biellette 28a, sous l'effet du coulisseau 210a, entraîne l'arceau de maintien 27, de façon qu'il prenne la position adéquate, dans un plan sensiblement horizontal, pour protéger l'enfant. Tant que la poussette est maintenue en position déployée, l'arceau de maintien 27 ne peut être déplacée, du fait que le coulisseau 210a est immobilisé.When unfolding, the push arm 8a is brought up. The termination sleeve 24a drives the slide 210a towards the connecting element 18a, until it comes into contact with the latter. The slider 210a is then immobilized, between the termination element 24a and the connecting element 18a. The link 28a, under the effect of the slide 210a, drives the retaining arch 27, so that it takes the appropriate position, in a substantially horizontal plane, to protect the child. As long as the stroller is kept in the deployed position, the retaining bar 27 cannot be moved, because the slider 210a is immobilized.
Dans le plan horizontal, l'arceau 27 s'est automatiquement déplié, du fait de l'écartement des éléments de liaison 18a et 18b.In the horizontal plane, the arch 27 has automatically unfolded, due to the spacing of the connecting elements 18a and 18b.
Ainsi, selon l'invention, la mise en place de l'arceau de maintien en position déployée et son repliage sous une forme compacte en position pliée, qui nécessite un double mouvement, repliage de l'arceau et basculement de ce dernier sont automatiques, simples et sûrs. Le cas échéant, des moyens de rappel (non représentés) peuvent être ajoutés, pour rendre plus rapide et/ou plus complet le pliage et/ou le dépliage. 6-3- sécurité anti-repliementThus, according to the invention, the positioning of the retaining arch in the deployed position and its folding back into a compact form in the folded position, which requires a double movement, folding of the arch and tilting of the latter are automatic, simple and safe. If necessary, return means (not shown) can be added, to make folding and / or unfolding faster and / or more complete. 6-3- anti-aliasing security
Le dispositif de sécurité anti-repliement de l'invention peut être adapté à la plupart des poussettes pliantes de type coulissant, et notamment celles du type présenté sur les figures 1 et 2. Selon l'invention, la poussette comprend des moyens de sécurité pour empêcher un dépliage intempestif de la poussette, lorsqu'un enfant est présent dans le hamac. Ces moyens de sécurité sont conçus de façon qu'ils empêchent ou limitent fortement, le coulissement des bras-poussoirs 8a et 8b le long des piètements correspondants 2a et 2b, lorsqu'un enfant est présent dans le hamac étant en revanche qu'il ne perturbe pas du tout ce coulissement dans le cas contraire.The anti-folding safety device of the invention can be adapted to most folding type pushchairs of the sliding type, and in particular those of the type shown in FIGS. 1 and 2. According to the invention, the stroller comprises safety means to prevent inadvertent unfolding of the stroller when a child is present in the hammock. These safety means are designed so that they strongly prevent or limit the sliding of the push arms 8a and 8b along the corresponding legs 2a and 2b, when a child is present in the hammock, on the other hand being unable to not disturb this sliding at all otherwise.
De tels systèmes peuvent être mis en oeuvre de plusieurs façons. On décrit maintenant plus en détail un mode de réalisation particulier, illustré par les figures 12, 13A et 13B. Dans la suite de la description, on présente un unique ensemble de moyens de sécurité, associés à l'ensemble latéral indicé -a- de la poussette. Un seul dispositif de ce type est a priori suffisant. On peut toutefois bien sûr équiper symétriquement les deux côtés de la poussette.Such systems can be implemented in several ways. A particular embodiment will now be described in more detail, illustrated by FIGS. 12, 13A and 13B. In the following description, a single set of safety means is presented, associated with the side assembly labeled - a of the stroller. A single device of this type is a priori sufficient. However, it is of course possible to fit the two sides of the stroller symmetrically.
L'extrémité inférieure du bras-poussoir 8a porte donc un élément de sécurité 131. En figure 12, la poussette se trouve en position déployée. Dans cette position, l'élément de sécurité 131 se trouve au voisinage du manchon de liaison 18a (ou en contact avec celui-ci) . Il peut ainsi jouer le rôle de butée.The lower end of the push arm 8a therefore carries a safety element 131. In FIG. 12, the stroller is in the deployed position. In this position, the security element 131 is located in the vicinity of the connecting sleeve 18a (or in contact with it). It can thus play the role of stop.
L'élément de sécurité 131 comprend 2 parties : une partie fixe 1311 qui correspond à l' extrémité du bras poussoir ; - une partie 1312 mobile en rotation autour du bras-poussoir 8a.The security element 131 comprises 2 parts: a fixed part 1311 which corresponds to the end of the pusher arm; - A part 1312 movable in rotation around the pusher arm 8a.
En d'autres termes, la partie mobile 1312 est montée sur le bras-poussoir 8a, entre le manchon 18a, contre lequel elle peut venir en butée, et la partie fixe d'extrémité 1311 de laquelle elle est solidaire.In other words, the mobile part 1312 is mounted on the push arm 8a, between the sleeve 18a, against which it can abut, and the fixed end part 1311 of which it is integral.
Le mouvement de rotation de la partie mobile 1312 est limité entre deux positions extrêmes, par exemple à l'aide d'un plot fixe (non représenté) monté sur le bras-poussoir et circulant dans un trou oblong (non représenté) réalisé dans la partie mobile.The rotational movement of the movable part 1312 is limited between two extreme positions, for example using a fixed stud (not shown) mounted on the push arm and circulating in an oblong hole (not shown) made in the mobile part.
La partie mobile 1312 comprend un prolongement plan 1313 (apparaissant plus nettement en figure 13A et 13B, qui présente la partie mobile vue de dessus) s'étendant perpendiculairement à l'axe défini par le bras poussoir 8a. Ce prolongement 1313 présente notamment : une ouverture 1314 (qui pourrait être une simple encoche) et dans laquelle s'inscrit la tringle 136a portant le hamac (par l'intermédiaire du passant 135a. Bien sûr, la sangle et/ou le hamac peuvent être fixés de façon différente, par exemple directement sur l'élément de sécurité 131, sans la tringle ; une butée 1315, prévue pour venir en contact avec le plot 132 placé à cet effet sur le piètement 2a, en position de sécurité (le plot 132a est représenté en pointillé pour illustrer le fait qu'il se trouve à l'arrière du piètement 2a). L'ouverture 1314 permet avantageusement le coulissement de la tringle 136a, afin d'assurer le guidage du hamac (lors du pliage, du dépliage et de la modification de l'inclinaison du hamac).The mobile part 1312 comprises a planar extension 1313 (appearing more clearly in FIGS. 13A and 13B, which presents the mobile part seen from above) extending perpendicular to the axis defined by the pusher arm 8a. This extension 1313 presents in particular: an opening 1314 (which could be a simple notch) and in which is inscribed the rod 136a carrying the hammock (via the loop 135a. Of course, the strap and / or the hammock can be fixed differently, by example directly on the security element 131, without the rod; a stop 1315, intended to come into contact with the stud 132 placed for this purpose on the base 2a, in the safety position (the stud 132a is shown in dotted lines to illustrate the fact that it is at the rear of the base 2a). The opening 1314 advantageously allows the sliding of the rod 136a, in order to ensure the guiding of the hammock (during folding, unfolding and modification of the 'tilt of the hammock).
Des moyens de rappel (non représentés) sont prévus dans l'élément de sécurité 131. Ces moyens de rappel sont montés entre la partie fixe 1311 et la partie mobile 1312, de façon à appliquer une force de rappel ramenant la partie 1312 dans une position telle que la butée 1315 ne se trouve plus en regard du plot 132. La force de rappel est définie de façon que : elle soit suffisant pour ramener la partie mobile 1312 en position de libération, dans laquelle la butée n'est plus en regard avec le plot, malgré le poids du hamac, lorsque celui-ci est vide (position de libération : figureReturn means (not shown) are provided in the security element 131. These return means are mounted between the fixed part 1311 and the movable part 1312, so as to apply a return force bringing the part 1312 into a position such that the stop 1315 is no longer located opposite the stud 132. The restoring force is defined so that: it is sufficient to bring the movable part 1312 back into the release position, in which the stop is no longer facing the stud, despite the weight of the hammock, when it is empty (release position: figure
13A) ; mais qu'elle soit insuffisante pour lutter contre la force appliquée par le poids d'un enfant présent dans le hamac (position de sécurité : figure13A); but that it is insufficient to combat the force applied by the weight of a child present in the hammock (safety position: figure
13B). Ces moyens de rappel comprennent par exemple un ressort hélicoïdal. L'effet de rappel peut également être obtenu par l'utilisation d'un matériau élastique adapté, ou tout autre moyen de rappel. Le tarage des moyens de rappel est réalisé de façon que, par exemple, tout poids supérieur à 3 kg empêche le repliage.13B). These return means comprise for example a helical spring. The restoring effect can also be obtained by the use of a suitable elastic material, or any other restoring means. The calibration of the return means is carried out so that, for example, any weight greater than 3 kg prevents folding.
Le fonctionnement du dispositif de sécurité est donc le suivant. Lorsqu'un déverrouillage est commandé (par exemple par action sur le guidon 10), le piètement 8a commence à coulisser à l'intérieur du manchon 18a, jusqu'au niveau du plot 132. Le jeu ainsi introduit correspond au jeu nécessaire pour la mise en oeuvre des moyens de verrouillage/déverrouillage, qui permet de visualiser le début du déverrouillage.The operation of the safety device is therefore as follows. When an unlocking is commanded (for example by action on the handlebars 10), the base 8a begins to slide inside the sleeve 18a, up to the level of the stud 132. The play thus introduced corresponds to the play necessary for the implementation of the locking / unlocking means, which makes it possible to visualize the beginning of the unlocking.
Lorsqu'un enfant est présent dans le hamac, son poids, par l'intermédiaire du passant 135a et de la tringle 136a, maintient la partie mobile 1312 en position de sécuritéWhen a child is present in the hammock, its weight, through the loop 135a and the rod 136a, keeps the mobile part 1312 in the safety position
(flèche 242). La butée 1315 vient alors en contact avec le plot 132, et le coulissement du bras est interrompu. Le hamac conserve ainsi son intégrité, et l'enfant ne court donc aucun risque.(arrow 242). The stop 1315 then comes into contact with the stud 132, and the sliding of the arm is interrupted. The hammock thus retains its integrity, and the child therefore does not run any risk.
En l'absence d'enfant, ou après que l'on ait retiré ce dernier, la force de rappel agit dans le sens de la flèche 241, pour amener la pièce mobile 1312 en position de libération, dans laquelle la butée 1315 ne se trouve plus en regard du plot 132. Le coulissement du bras 8a poussoir peut alors continuer, et le pliage se terminer.In the absence of a child, or after the latter has been removed, the restoring force acts in the direction of the arrow 241, to bring the moving part 1312 into the release position, in which the stop 1315 is not is closer to the block 132. The sliding of the push arm 8a can then continue, and the folding is completed.
Le dispositif décrit ci-dessus peut être adapté à d'autres poussettes pliantes. Par ailleurs, d'autres modes de réalisation peuvent être envisagés pour réaliser les moyens de sécurité, dès lors que ces derniers peuvent prendre deux positions, la position de libération et la position de sécurité, en fonction de la présence ou non d'un enfant dans le hamac. The device described above can be adapted to other folding strollers. Furthermore, other embodiments can be envisaged for producing the safety means, since the latter can take two positions, the release position and the safety position, depending on the presence or not of a child. in the hammock.
