Abstract

The folding rod type frame for a child's push chair has two parallel rods (1a,1b), each ending in a pair of clamping jaws (10,11). These rods can move between a use position (of maximum length) and a minimum length. The two parts can be locked together in the extended operative position. One slides w.r.t the other and each rod has a stop to limit the movement. The parts are pivoted (8) together at their ends on an intermediate link (7).

Description

Perfectionnement aux ch ssis de voitures d'enfant pliables en miton. Improvement to the chassis of collapsible baby cars in mitons.

Les châssis des poussettes dites '1cannes" ou des voitures d'enfant, qui se replient en bâton, offrent beaucoup d'avantages par le peu de volume qu'ils occupent en position repliée. The chassis of strollers known as "1cannes" or baby carriages, which fold into sticks, offer many advantages by the little volume they occupy in the folded position.

Cependant, la longueur de ces chassis dans cette position est relativement importante et peut créer une pêne, notamment pour le rangement de la poussette dans la malle arrière d'un petit véhicule. En effet, cette longueur 1 notée sur la figure 1, qui illustre schématiquement une telle poussette, est souvent supérieure à la largeur de la malle. Or, les dimensions de tous les éléments du chassies ne sont pas facilement modifiables, car leurs diverses longueurs et la place des articulations conditionnent l'empattement de la poussette, la hauteur de la nacelle, le bras de levier permettant la manoeuvre de la poussette, etc., autant de facteurs sur lesquels on ne peut pas agir sans conséquence sur la stabilité ou la maniabilité de la voiture.However, the length of these frames in this position is relatively large and can create a bolt, especially for storing the stroller in the trunk of a small vehicle. Indeed, this length 1 noted in Figure 1, which schematically illustrates such a stroller, is often greater than the width of the trunk. However, the dimensions of all the elements of the chases are not easily modifiable, because their various lengths and the place of the joints condition the wheelbase of the stroller, the height of the nacelle, the lever arm allowing the operation of the stroller, etc., all of which cannot be acted upon without affecting the stability or handling of the car.

L'invention entend remédier à ces inconvénients en proposant un perfectionnement simple aux châssis de poussettescannes qui, de manière connue comporte deux éléments parallèles, chacun terminé par une poignée. The invention intends to remedy these drawbacks by proposing a simple improvement to the chassis of pushchairs which, in known manner comprises two parallel elements, each terminated by a handle.

Selon l'invention, chaque élément susdit est en deux parties mobiles l'une par rapport à l'autre entre une position d'utilisation correspondant à la longueur maximale de l'élément et une position de rangement correspondant à la longueur minimale de l'elément, et comporte en outre un moyen de verrouillage mutuel des deux parties dans ladite position d'utilisation. According to the invention, each aforementioned element is in two parts which are movable relative to each other between a position of use corresponding to the maximum length of the element and a storage position corresponding to the minimum length of the element, and further comprises means for mutual locking of the two parts in said position of use.

Dans un premier mode de réalisation de l'invention, l'une des parties susdites équipée de la poignée est coulissante par rapport A l'autre partie, le moyen de verrouillage étant alors constitué par des éléments de butée portés par les deux parties et dont l'un est escamotable. In a first embodiment of the invention, one of the abovementioned parts equipped with the handle is sliding relative to the other part, the locking means then being constituted by abutment elements carried by the two parts and of which one is retractable.

Dans un second mode de réalisation, lesdites deux parties sont articulées par l'une de leurs extrémités sur une pièce intermédiaire d'articulation. Le moyen de verrouillage susdit est alors un manchon coulissant sur lesdites parties pour venir recouvrir leur extrémité articulée et la pièce intermédiaire susdite lorsque ladite première position est atteinte. De manière préférée, l'axe de chacune des articulations est perpendiculaire au plan contenant lesdits éléments de châssis. In a second embodiment, said two parts are articulated by one of their ends on an intermediate articulation part. The aforementioned locking means is then a sliding sleeve on said parts to come to cover their articulated end and the aforementioned intermediate part when said first position is reached. Preferably, the axis of each of the articulations is perpendicular to the plane containing said chassis elements.

L'invention sera mieux comprise au cours de la description donnée ci-après à titre d'exemple purement indicatif et non limitatif qui permettra d'en degager les avantages et les caractéristiques secondaires. The invention will be better understood during the description given below by way of purely indicative and non-limiting example which will make it possible to identify the advantages and the secondary characteristics thereof.

Il sera fait référence aux dessins annexés, dans lesquels
- la figure 1 illustre schématiquement une poussettecanne repliée de manière connue;
- les figures 2A et 2B constituent des schémas d'une première réalisation du perfectionnement selon l'invention;
- la figure 3 est une vue schématique d'une seconde réalisation de ce perfectionnement.
Reference will be made to the accompanying drawings, in which
- Figure 1 schematically illustrates a stroller folded in a known manner;
- Figures 2A and 2B are diagrams of a first embodiment of the improvement according to the invention;
- Figure 3 is a schematic view of a second embodiment of this improvement.

On voit donc sur la figure 1 qu'une poussette canne repliée possède une longueur 1 et que les éléments qui influencent de manière importante cette longueur sont deux longerons 1 qui portent les poignées2 de la poussette. Ces longerons doivent en effet être de longueur suffisante pour qu'en position dépliée ils soient situés suffisamment décalés vers l'arrière par rapport à la verticale passant par les roues arrière afin que le bras de levier qu'ils constituent ainsi soit important. Lever les roues avant de la poussette est une opération qui, alors, s'effectue sans difficulté en appuyant sur les poignées. La conséquence d'un tel impératif associé à l'architecture générale du chassies de la poussette est,comme le montre la figure 1, le déport important d de la partie extrême de ces longerons 1 par rapport au reste de la structure. It can therefore be seen in FIG. 1 that a folded cane stroller has a length 1 and that the elements which significantly influence this length are two side members 1 which carry the handles2 of the stroller. These beams must indeed be of sufficient length so that in the unfolded position they are located sufficiently offset towards the rear with respect to the vertical passing through the rear wheels so that the lever arm which they thus constitute is large. Raising the front wheels of the stroller is an operation which is then carried out without difficulty by pressing the handles. The consequence of such an imperative associated with the general architecture of the stroller chasing is, as shown in FIG. 1, the large offset d of the extreme part of these beams 1 relative to the rest of the structure.

Sur les figures 2A et 2B, on a représenté une solution pour réduire ce déport. Chaque longeron 1 est constitué de deux parties la et lb, la partie lb étant située du côte de la structure et la partie la étant équipée des poignées. La partie lb comporte un rivet 3 de fixation d'une pièce 4 connue en elle-même sur laquelle est articulée l'extrémité d'une barre du croisillon arrière (non représentée) du chassies. La partie la susdite est montée à coulissement dans la partie lb et présente deux fentes 5 et 6 opposées pour le passage du rivet 3. Ces fentes ont une longueur correspondant à la course possible de la partie la par rapport à la partie lb.  In FIGS. 2A and 2B, a solution has been shown to reduce this offset. Each spar 1 is made up of two parts 1a and 1b, the part 1b being situated on the side of the structure and the part 1a being equipped with handles. The part 1b comprises a rivet 3 for fixing a part 4 known in itself on which is articulated the end of a bar of the rear spider (not shown) of the casings. The above-mentioned part is slidably mounted in the part lb and has two opposite slots 5 and 6 for the passage of the rivet 3. These slots have a length corresponding to the possible stroke of the part la relative to the part lb.

Le raccourcissement de la partie d (figure 1) est donc déterminé par la longueur de ces fentes. Le rivet 3 constitue également un~elément de butée coopérant avec des prolongations 5a et 6a des fentes 5 et 6 pour verrouiller la partie la dans sa position sortie. En effet, après avoir tiré ladite partie la, on lui fait subir une légère rotation afin de loger le rivet 3 dans les prolongations Sa et 6a susdites qui constituent des éléments de butée escamotables coopérant avec le rivet au verrouillage de la partie la dans cette position. On peut également prévoir que l'extrémité des portions Sa 6a susdites soit prolongée par des encoches parallèles aux fentes 5 et 6 pour constituer, sous l'effet d'une légère rétraction de la partie la un logement pour le rivet qui verrouillerait alors la partie la également en rotation.The shortening of part d (Figure 1) is therefore determined by the length of these slots. The rivet 3 also constitutes a stop element cooperating with extensions 5a and 6a of the slots 5 and 6 to lock the part in its extended position. In fact, after having drawn said part 1a, it is made to undergo a slight rotation in order to accommodate the rivet 3 in the above-mentioned extensions Sa and 6a which constitute retractable stop elements cooperating with the rivet for locking the part 1a in this position. . It can also be provided that the end of the portions Sa 6a above is extended by notches parallel to the slots 5 and 6 to constitute, under the effect of a slight retraction of the part 1a housing for the rivet which would then lock the part also in rotation.

Sur la figure 3, une deuxième solution est représentée pour réduire la longueur des longerons 1. La partie la est articulée A son extrémité A une pièce d'articulation 7, elle-meme articulée A l'extrémité de la partie lb. Les axes d'articulation 8 seront sensiblement perpendiculaires au plan contenant les longerons 1, de manière que les cannes (longerons) puissent etre "cassées" latéralement. Le maintien en position d'alignement des parties la et lb est assuré par un manchon 9 escamotable monté à coulissement sur la partie lb et placé en chevauchement des deux parties. I1 viendra alors buter sur la pièce de liaison 4 susdite. Cette réalisation présente l'avantage d'étire plus simple en fabrication et de disposer de parties la lb de meme diamètre. Les chapes d'articulation de la pièce intermédiaire 7 seront constituées par des pièces rapportées 10 et 11 embouchées aux extrémités des parties la, lb qui sont tubulaires. In FIG. 3, a second solution is shown to reduce the length of the longitudinal members 1. The part 1a is articulated at its end To a hinge part 7, itself articulated At the end of the part 1b. The articulation axes 8 will be substantially perpendicular to the plane containing the side members 1, so that the rods (side members) can be "broken" laterally. Maintaining in position of alignment of the parts la and lb is ensured by a retractable sleeve 9 slidably mounted on the part lb and placed in overlap of the two parts. I1 will then come up against the aforementioned connecting piece 4. This embodiment has the advantage of simpler stretching in manufacture and of having parts 1b of the same diameter. The articulation yokes of the intermediate part 7 will consist of added parts 10 and 11 which are fitted at the ends of the parts la, lb which are tubular.

L'invention trouve une application intéressante dans le domaine des articles de puériculture. The invention finds an interesting application in the field of childcare articles.
