les Lubes de poignde sur les pieds arriAre (10).the handle Lubes on the rear feet (10).
- 1 La presente invention concerne une voiture pliable pour le - 1 The present invention relates to a foldable car for the
transport d'enfant type poussette et pourra etre utilise d'autres fins. stroller type child transport and can be used for other purposes.
Les voitures pliables pour enfant comportent traditionnellement trots a quatre roues porteuses. Leur systeme de pliage se fait de plusieurs fa, cons possibles: soit en reprennant le pliage parapluie reduisant le chassis dans sa largeur et dans sa profondeur, soit en applatissant le chariot a ['aide d'un systeme telescopique, soit en le reduisant en plusieurs actions, le chassis etant alors dote de plusieurs axes de rotation pour le pliage. Les chassis actuels vent munis de double poignees ou de poignee en U impliquant, le plus souvent, un pliage a deux mains. La manipulation des poussettes actuelles se fait a deux mains. Les acces aux trottoirs et aux Foldable cars for children have traditionally had four-wheeled trots. Their folding system is done in several ways, possible cons: either by resuming umbrella folding reducing the chassis in width and depth, or by flattening the cart using a telescopic system, or by reducing it by several actions, the chassis then being provided with several axes of rotation for folding. Current chassis are fitted with double handles or a U-shaped handle, most often involving folding with two hands. The handling of current strollers is done with two hands. Access to sidewalks and
escaliers ne vent pas toujours faciles. stairs are not always easy.
Le dispositif selon ['invention permet de remedier a cet inconvenient. II comporte en effet, selon une premiere caracteristique, une poignee unique solidaire d'un bras telescopique (compose de trots tubes) faisant office de corps de support central; deux jambes de roue, solidaires du support central, a gauche et a droite de ce dernier et sur lesquels vent montees deux roues; deux tiges cylind riques sol id aires d u support central par un axe rejoignent les deux jambes de roue en leur centre; une tige horizontale, reliant les deux roues arrieres, est separee en son centre par une pedale faisant office de frein et permettant de verrouiller le depliage. De part et d'autre de cette pedale, deux axes permettent le pliage de la tige en trots parties; une petite roue libre avant, positionnee a ['oppose de la poignee (par rapport au support central) protegee d'un capotage type garde boue; et une piece sur The device according to the invention makes it possible to remedy this drawback. It indeed has, according to a first characteristic, a single handle secured to a telescopic arm (composed of trotting tubes) acting as a central support body; two wheel legs, secured to the central support, to the left and right of the latter and on which two wheels are mounted; two ideal cylindrical ground rods of central support by an axis join the two wheel legs in their center; a horizontal rod, connecting the two rear wheels, is separated in its center by a pedal acting as a brake and allowing to lock the unfolding. On either side of this pedal, two axes allow the folding of the rod into trots parts; a small front freewheel, positioned opposite the handle (relative to the central support) protected by a cowling type guard; and a piece on
laquelle viennent s'accrocher les assises qui recevront l'enfant. which hang the seats that will receive the child.
Selon une seconde caracteristique, le centre de gravite de l'assise, deplace vers les deux roues arribres porteuses, permet a l'utilisateur de soulever le poids de l'assise et de l'enfant de maniere plus confortable lors de l'acces aux troittoirs, ou le basculement vers l'arriere se fait plus naturellement avec la poignee unique et le support central servant de levier, L'acces aux escaliers devient alors possible en tirant la voiture pour enfant tout en prenant appui sur les deux roues arrieres porteuses. Un diametre According to a second characteristic, the center of gravity of the seat, moved towards the two load-bearing wheels, allows the user to lift the weight of the seat and of the child in a more comfortable manner when accessing the sidewalks, or tilting backwards is more natural with the single handle and the central support acting as a lever. Access to the stairs then becomes possible by pulling the car for children while resting on the two rear carrying wheels. A diameter
consequent des roues assure l'acces a tout type de marches. Consequently wheels ensure access to all types of steps.
Les dessins annexes illustrent ['invention: The accompanying drawings illustrate the invention:
La figure 1 represente en plan le descriptif de ['invention (fig.1A, fig. 1B, fig.1C). Figure 1 shows in plan the description of the invention (fig.1A, fig. 1B, fig.1C).
La figure 2 represente en vue de profile le dispositif de ['invention concernant -2 Figure 2 shows in profile view the device of the invention relating to -2
le pliage de la voiture pour enfant (fig.2A, fig.2b, fig.2C). folding the child car (fig.2A, fig.2b, fig.2C).
En reference a ces dessins, le dispositif comporte un bras telescopique (ou support central) compose de trots parties: le premier cylindre (1), solidaire de la poignee (4), comprend une section tubulaire inferieure et penetre dans le second cylindre (2) de section tubulaire mediane qui lui, a son tour, penetre dans le troisieme cylindre (3) a section tubulaire suprieure. Une longueur de penetration d'au moins 15 centimetres est a respecter pour que chacun des tubes soit bien solidaire. Un anneau de guidage conique vient With reference to these drawings, the device comprises a telescopic arm (or central support) composed of three trots: the first cylinder (1), integral with the handle (4), comprises a lower tubular section and penetrates into the second cylinder (2 ) of median tubular section which, in turn, penetrates into the third cylinder (3) with upper tubular section. A penetration length of at least 15 centimeters must be observed so that each of the tubes is securely attached. A conical guide ring comes
renforcer leur emboTtement.reinforce their nesting.
Lors du pliage, le cylindre (1) rentre dans le cylindre (2) et le pousse a son tour. Le cylindre (2) est solidaire par un axe de rotation (20) a deux tiges cylindriques (16a et 16b) elles-memes reliees aux jambes de roues (5a et 5b) en leur centre. La poussee du cylindre (2) dans le cylindre (3) entraine son retressissement et de ce fait, fait descendre l'axe retenant les deux tiges cylindriques (16a et 16b). Cette action entraine une reaction en chane: les deux tiges cylindriques rigides (16a et 16b) poussent a leur tour les deux jambes de roue (5a et 5b), solidaires elles du cylindre (3) par le biais d'une piece (10) rivetee (par exemple) de part et d'autre du cylindre (3). Les deux jambes de roue vent solidaires d'une roue porteuse arriere (6a et 6b) chacune. La piece (10) a une forme de U dans laquelle viennent se ioger les jambes de roue (5a et 5b) montees sur un axe de rotation (11 et 12). Le pivot des jambes de roue en ces deux axes (11 et 12) permet de ramener les roues (6a et 6b) vers la petite roue avant (7, 8) jusqu'a ce qu'elles l'encadrent et la serrent. Le cylindre (1), en se telescopant dans les deux autres cylindres (2 et 3), provoque la descente de la piece (9), solidaire du cylindre (1) grace a un collier serre (26) par une tige filetee munie d'un boulon. Cette piece (9) glisse, guidee par un anneau (27), sur le cylindre (3). Cette descente de la piece (9) provoque done aussi la descente de l'assise (17), accrochee dessus, vers la petite roue avant (8) . La tige (15) se plie en trots parties, remontant la pedale (14) vers le haut. L'ensemble est alors completement plie. Ce dispositif permet When folding, the cylinder (1) enters the cylinder (2) and pushes it in turn. The cylinder (2) is secured by an axis of rotation (20) to two cylindrical rods (16a and 16b) themselves connected to the wheel legs (5a and 5b) in their center. The pushing of the cylinder (2) in the cylinder (3) causes it to shrink and therefore causes the axis retaining the two cylindrical rods (16a and 16b) to descend. This action causes a chain reaction: the two rigid cylindrical rods (16a and 16b) in turn push the two wheel legs (5a and 5b), integral with the cylinder (3) by means of a part (10) riveted (for example) on either side of the cylinder (3). The two wind wheel legs secured to a rear carrier wheel (6a and 6b) each. The part (10) has a U shape in which the wheel legs (5a and 5b) come to be mounted on an axis of rotation (11 and 12). The pivot of the wheel legs in these two axes (11 and 12) allows the wheels (6a and 6b) to be brought back towards the small front wheel (7, 8) until they frame and tighten it. The cylinder (1), by telescoping into the two other cylinders (2 and 3), causes the lowering of the part (9), integral with the cylinder (1) thanks to a clamp (26) by a threaded rod provided with 'A bolt. This piece (9) slides, guided by a ring (27), on the cylinder (3). This descent of the part (9) therefore also causes the descent of the seat (17), hooked on it, towards the small front wheel (8). The rod (15) folds into three parts, raising the pedal (14) upwards. The assembly is then completely folded. This device allows
un pliage compact actionnable a une seule main. compact folding that can be operated with one hand.
L'accroche de l'assise (17) sur la piece (9) se fait par l'intermediaire d'une fixation amovible telle qu'un clip, par exemple. Le dessous de la coque (21) est tel que l'utilisateur puisse avoir acces aux boutons lateraux (22 et 23) permettant le detachement de l'assise (17). D'autres types The attachment of the seat (17) on the part (9) is done by means of a removable fixing such as a clip, for example. The underside of the shell (21) is such that the user can have access to the side buttons (22 and 23) allowing detachment of the seat (17). Other types
d'assises pourront venir staccrocher sur la piece (9). seats can hang on the piece (9).
-3 Lorsque la voiture pour enfant est deployee, la position de l'assise par rapport aux deux roues porteuses (6a et 6b) est telle qu'un falble appui sur la poignee multiplie la force de l'utilisateur et l'assiste done dans ses actions lors du deplacement. Des suspensions (24 et 25) accompagnent et aident l'utilisateur dans ses efforts. Wiles permettent aussi un confort pour l'enfant. Les trots roues de cette voiture pour enfant ont une fonction precise puisque seules les deux roues arrieres vent porteuses. La petite roue -3 When the children's car is deployed, the position of the seat relative to the two carrying wheels (6a and 6b) is such that a falble support on the handle multiplies the force of the user and therefore assists him in its actions during displacement. Suspensions (24 and 25) accompany and help the user in his efforts. Wiles also provide comfort for the child. The trotting wheels of this child car have a precise function since only the two rear wheels are load-bearing. The little wheel
libre (8) a ['avant aide au guidage et assure une direction precise sur le terrain. free (8) at the front helps guide and provides precise direction on the ground.
Son role est aussi de stabiliser l'horizontalite de l'assise pour que l'enfant ne Its role is also to stabilize the horizontality of the seat so that the child does not
soit pas secoue.don't shake.
La poignee unique (4) peut proposer, selon une variante, un deplolement lateral, de part et d'autre, de deux poignees (1 9a et 1 9b) chacune solidaire de la poignee centrale par un axe, permettant ainsi a l'utilisateur de pousser dans les cotes, en cas de necessite. Ce systeme de rabattement des The single handle (4) can propose, according to a variant, a lateral movement, on either side, of two handles (1 9a and 1 9b) each secured to the central handle by an axis, thus allowing the user to push in the dimensions, if necessary. This drawdown system
deux poignees evite une gene lors de leur non utilisation. two handles avoid discomfort when not in use.
A titre d'exemple non limitatif, le bras telescopique peut etre en aluminium anodise, ainsi que les jambes de roue et la tige (15) encadrant la pedale (14). La poignee, le pare-choc avant (7) et les jantes de roues (6a et 6b) peuvent etre en polyacetal. La piece (9) recevant les assises et la coque By way of nonlimiting example, the telescopic arm can be made of anodized aluminum, as well as the wheel legs and the rod (15) framing the pedal (14). The handle, the front bumper (7) and the wheel rims (6a and 6b) can be made of polyacetal. The part (9) receiving the seats and the shell
de l'assise (17) peuvent etre en polyethylene. of the seat (17) can be made of polyethylene.
Le dispositif selon ['invention peut etre utilise a d'autre fin que le The device according to the invention can be used for other purposes than the
