Description

L'invention est relative aux voitures d'enfant pliantes qui comportent un châssis repliable sur lui-même, ce châssis étant monté sur des roues et portant une nacelle ou analogue pour la réception de l'enfant. The invention relates to collapsible baby cars which have a foldable frame on itself, this frame being mounted on wheels and carrying a nacelle or the like for the reception of the child.

Parmi ces voitures pliantes, l'invention s'applique en particulier à celles qui sont du type à repliage en fagot, le repliage de la voiture se faisant, dans ce cas, à la fois en direction longitudinale et en direction transversale. Among these folding cars, the invention applies in particular to those which are of the folding-in-bundle type, the folding of the car taking place, in this case, both in the longitudinal direction and in the transverse direction.

L'invention a pour but de fournir une nouvelle structure de voiture de ce genre qui soit particulièrement simple, économique et robuste. The invention aims to provide a new car structure of this kind which is particularly simple, economical and robust.

A cet effet, la voiture d'enfant pliante selon l'invention, comportant un châssis repliable monté sur roues, portant une nacelle ou analogue et constitué, d'une part, par deux ensembles latéraux de châssis reliés par deux organes inférieur et arrière d'entretoisement transversal, est caractérisée par le fait que chaque ensemble latéral de châssis comporte : un élément porteur principal constitué par deux parties articulées l'une sur l'autre à leurs extrémités adjacentes, la partie inférieure portant une roue avant et la partie supérieure portant une poignée ou analogue ; un montant arrière articulé à son extrémité supérieure sur la partie supérieure de l'élément principal et portant une roue arrière à son extrémité inférieure ; et une bielle de liaison articulée à une extrémité au voisinage de l'extrémité inférieure du montant et, à son autre extrémité, sur la partie inférieure de l'élément porteur principal, l'organe d'entretoisement inférieur étant constitué par un croisillon dont les bras sont articulés sur la partie inférieure de I'élément porteur principal et au voisinage de l'extrémité inférieure du montant, et l'organe d'entretoisement arrière étant constitué également par un croisillon dont les bras sont articulés au voisinage de l'extrémité inférieure du montant et sur un coulisseau propre à se déplacer sur ce montant. To this end, the folding baby carriage according to the invention, comprising a folding chassis mounted on wheels, carrying a nacelle or the like and consisting, on the one hand, of two lateral chassis assemblies connected by two lower and rear members d transverse bracing, is characterized in that each lateral chassis assembly comprises: a main support element constituted by two parts articulated one on the other at their adjacent ends, the lower part carrying a front wheel and the upper part carrying a handle or the like; a rear upright articulated at its upper end on the upper part of the main element and carrying a rear wheel at its lower end; and a connecting rod articulated at one end in the vicinity of the lower end of the upright and, at its other end, on the lower part of the main support element, the lower bracing member being constituted by a crosspiece whose arms are articulated on the lower part of the main load-bearing element and in the vicinity of the lower end of the upright, and the rear bracing member also consists of a spider, the arms of which are articulated in the vicinity of the lower end of the upright and on a slide suitable for moving over this upright.

Ainsi, dans la structure selon l'invention, chaque ensemble latéral de châssis est constitué par seulement trois éléments : l'élément porteur principal, le montant et la bielle. Thus, in the structure according to the invention, each lateral set of chassis consists of only three elements: the main support element, the upright and the connecting rod.

On comprendra bien l'invention à la lecture de la description qui va suivre et en référence au dessin annexé dont la figure unique est une vue latérale d'une voiture d'enfant selon l'invention. The invention will be clearly understood on reading the description which follows and with reference to the accompanying drawing, the single figure of which is a side view of a baby carriage according to the invention.

La voiture d'enfant représentée sur la figure est une poussette du type "canne" et repliable. Elle comporte un châssis 1 qui est monté sur des roues avant 2 et sur des roues arrière 3. The baby carriage shown in the figure is a folding "cane" type stroller. It comprises a chassis 1 which is mounted on front wheels 2 and on rear wheels 3.

Le châssis 1 porte une nacelle 4 représentée en traits mixtes. De façon connue, la position de la nacelle 4 peut être inversée par rapport au sens de marche. The chassis 1 carries a nacelle 4 shown in phantom. In known manner, the position of the nacelle 4 can be reversed with respect to the direction of travel.

Le châssis 1 comporte deux ensembles latéraux de châssis 5 qui sont disposés symétriquement par rapport au plan longitudinal vertical médian de la poussette. Les deux ensembles 5 sont reliés par un organe d'entretoisement inférieur 6 et par un organe d'entretoisement arrière 7. The chassis 1 comprises two lateral chassis assemblies 5 which are arranged symmetrically with respect to the median vertical longitudinal plane of the stroller. The two assemblies 5 are connected by a lower bracing member 6 and by a rear bracing member 7.

Chaque ensemble latéral de châssis 5 est constitué, selon l'invention, de trois éléments : un élément porteur principal 8, un montant arrière 9 et une bielle de liaison 10. Each lateral chassis assembly 5 is made up, according to the invention, of three elements: a main support element 8, a rear upright 9 and a connecting rod 10.

L'élément porteur principal 8 est en deux parties 8a, 8b qui sont sensiblement dans le prolongement l'une de l'autre et en oblique. Les parties 8a, 8b sont articulées l'une sur l'autre, à leurs extrémités adjacentes, autour d'un pivot transversal 11 qui est porté par une chape 12 solidaire de l'extrémité supérieure de la partie inférieure 8b. Avantageusement, la chape 12 peut également servir de moyen de support pour la nacelle 4. La partie supérieure 8a porte, à son ex trémité supérieure, une poignée ou analogue 13. L'extrémité inférieure de la partie inférieure 8b porte la roue avant 2. The main support element 8 is in two parts 8a, 8b which are substantially in line with one another and at an angle. The parts 8a, 8b are articulated one on the other, at their adjacent ends, around a transverse pivot 11 which is carried by a yoke 12 secured to the upper end of the lower part 8b. Advantageously, the yoke 12 can also serve as a support means for the nacelle 4. The upper part 8a carries, at its upper end, a handle or the like 13. The lower end of the lower part 8b carries the front wheel 2.

Le montant 9 qui, pour la position déployée de la poussette, est sensiblement vertical, est articulé à son extrémité supérieure sur la partie 8a autour d'un pivottrans- versal 14 porté par une chape 15 solidaire de l'extrémité supérieure du montant. L'extrémité inférieure du montant 9 porte la roue arrière 3. La bielle 10 s'étend en oblique en montant vers l'avant. Son extrémité arrière basse est articu idée, autour d'un pivot transversal 16, au voisinage de l'ex trémité inférieure du montant 9 tandis que son extrémité supérieure avant est articulée autour-d'un pivot transversal 17 sur la partie inférieure 8b de l'élément porteur principal 8. The upright 9 which, for the deployed position of the stroller, is substantially vertical, is articulated at its upper end on the part 8a around a transverse pivot 14 carried by a yoke 15 secured to the upper end of the upright. The lower end of the upright 9 carries the rear wheel 3. The connecting rod 10 extends obliquely while mounting forward. Its lower rear end is articulated idea, around a transverse pivot 16, in the vicinity of the lower end of the upright 9 while its upper front end is articulated around a transverse pivot 17 on the lower part 8b of l main load-bearing element 8.

L'organe d'entretoisement inférieur 6 qui, de façon connue, est constitué par un croisillon à deux bras articulés autour d'un pivot central 18, est articulé à l'avant, au voisinage de l'extrémité inférieure de la partie 8b, autour d'une double articulation 19, tandis qu'il est articulé à l'arrière, au voisinage de l'extrémité inférieure du montant 9, autour d'une double articulation du même type (non repré sentée).  The lower bracing member 6 which, in known manner, consists of a crosspiece with two arms articulated around a central pivot 18, is articulated at the front, in the vicinity of the lower end of the part 8b, around a double articulation 19, while it is articulated at the rear, in the vicinity of the lower end of the upright 9, around a double articulation of the same type (not shown).

L'organe d'entretoisement arrière 7 qui, de façon également connue, est constitué par deux bras articulés autour d'un pivot central 20 d'axe sensiblement horizontal, est ar articulé à son extrémité inférieure, par un pivot 21 d'axe parallèle à celui du pivot 20, au voisinage de l'extrémité inférieure du montant 9, tandis que, à son extrémité supérieure, il est articulé par un pivot 22, d'axe parallèle à celui du pivot 20, sur un coulisseau ou manchon 23 agencé pour pouvoir se déplacer le long du montant 9 entre une position haute de repliage de la poussette et une position basse de déploiement de celle-ci. Le croisillon arrière 7 est équipé, de façon connue, d'un dispositif de verrouillage (non représenté) qui, quand la pousette est déployée, interdit aux deux montants 9 de se rapprocher l'un de l'autre. The rear bracing member 7 which, in a manner also known, consists of two arms articulated around a central pivot 20 of substantially horizontal axis, is articulated at its lower end, by a pivot 21 of parallel axis to that of pivot 20, in the vicinity of the lower end of the upright 9, while, at its upper end, it is articulated by a pivot 22, with an axis parallel to that of pivot 20, on a slide or sleeve 23 arranged to be able to move along the upright 9 between a high position for folding the stroller and a low position for deploying it. The rear spider 7 is equipped, in known manner, with a locking device (not shown) which, when the stroller is deployed, prevents the two uprights 9 from approaching each other.

Pour cette position de la poussette, le triangle défini par les articulations 14, 16 et 17 est indéformable grâce au verrouillage du croisillon arrière 7. Quand ce verrouillage est libéré, chaque coulisseau 23 peut se déplacer sur le montant associé 9, ce qui permet aux parties
8a, 8b de se rabattre l'une sur l'autre par basculement autour du pivot 11.For this position of the stroller, the triangle defined by the articulations 14, 16 and 17 is undeformable thanks to the locking of the rear spider 7. When this locking is released, each slide 23 can move on the associated upright 9, which allows the parts
8a, 8b to fold over one another by tilting around the pivot 11.

Bien entendu, l'invention n'est pas-limitée au mode de réalisation qui a été décrit ; on peut au contraire concevoir diverses variantes sans sortir pour autant de son cadre.  Of course, the invention is not limited to the embodiment which has been described; on the contrary, we can conceive of various variants without departing from its framework.
