Description

STRUCTURE REPLIABLE POUR VEHICULE ROULANT MANOEUVRABLE A LA MAIN TEL QUE POUSSETTEFOLDABLE STRUCTURE FOR HAND-HELD ROLLING VEHICLE SUCH AS A STROLLER
La présente invention concerne une structure repliable utilisable pour la réalisation de véhicules légers manoeuvres à la main et notamment des poussettes, ou encore des chariots pour le transport d'achats domestiques.The present invention relates to a folding structure usable for the production of light vehicles maneuvering by hand and in particular strollers, or even trolleys for the transport of domestic purchases.
On connaît de nombreuses formes de réalisation de poussettes repl iables.Many embodiments of folding strollers are known.
Ces poussettes repliables ont la faveur de la clientèle des jeunes ménages ici. concernés.These folding strollers are popular with young household customers here. concerned.
Toutefois elles restent d'une utilisation relativement limitée dans le temps et il est donc souhaitable qu'elle n'immobilise qu'un volume le plus réduit possible dans les habitations modernes où l'espace est mesuré et qu'elle trouve place dans un véhicule individuel ou de transport en commun.However, they remain of relatively limited use in time and it is therefore desirable that it immobilizes only the smallest possible volume in modern dwellings where space is measured and that it finds place in a vehicle. individual or public transport.
Répondent sensiblement à ces préoccupations, les poussettes du type repliable utilisées actuellement et notamment celles dénommées "poussettes canne" (FR-A-2.458.443, 2.406.555, 2.369.957). Elles comprennent notamment :Responding substantially to these concerns, the folding type strollers currently used and in particular those called "cane strollers" (FR-A-2,458,443, 2,406,555, 2,369,957). They include in particular:
- deux longerons inférieurs latéraux et symétriques et porteurs de moyens de roulement,- two lateral and symmetrical lower beams carrying bearing means,
- des organes d'accouplement articulés et aptes à relier entre eux les deux longerons en permettant leur rapprochement l 'un contre l 'autre dans leur position repliée et leur maintien écarté en position active, deux montants latéraux aptes à recevoir des organes souples (tels que poche ou hamac) support des objets ou sujets transportés, chaque montant étant relié par une liaison articulée sur un longeron support et étant déplaçable entre sa position active, et une position repliée contre son longeron support, le déplacement se faisant par pivotement selon la liaison articulée sur ledit longeron.- articulated coupling members capable of connecting the two side members together, allowing them to be brought one against the other in their folded position and kept apart in the active position, two lateral uprights capable of receiving flexible members (such that pocket or hammock) support for objects or subjects transported, each upright being connected by an articulated link on a support spar and being movable between its active position, and a folded position against its support spar, the displacement being made by pivoting according to the connection articulated on said spar.
Dans les poussettes connues, l 'articulation des montants se situe à l 'avant des longerons et pour le pliage les montants sont rabattus vers l 'arrière. Les montants étant plus longs que les longerons, leur partie supérieure reste toutefois en saillie, à moins d'être repliable, ce qui alors oblige à fixer les organes souples très bas, d'où un manque de confort. Leur repliage reste toutefois assez complexe et, même lorsque leurs montants sont également repliables, ce type de poussette présente encore un encombrement en longueur qui reste assez important, ce qui peut handicaper son logement sous sa forme repliée et compactée par exemple dans le coffre d'une voiture de petite cylindrée.In known pushchairs, the articulation of the uprights is located at the front of the side members and for folding the uprights are folded back. The uprights being longer than the side members, their upper part however remains projecting, unless it is foldable, which then means that the flexible members have to be fixed very low, hence a lack of comfort. However, their folding remains quite complex and, even when their uprights are also foldable, this type of stroller still has a lengthwise dimension which remains quite large, which can handicap its housing in its folded and compacted form, for example in the boot. a small displacement car.
Quant à l 'ensemble de l'armature support des organes souples, s'il peut généralement être basculé de manière à placer l'enfant vers l 'avant ou vers l'arrière, ses réglages de position restent toutefois très limités.As for the entire support frame of the flexible members, although it can generally be tilted so as to place the child forwards or backwards, its position adjustments remain very limited, however.
La présente invention vise à conserver et développer les avantages de la poussette repliable tout en obtenant, grâce aux modalités constructives mises en oeuvre, une compacité beaucoup plus poussée que précédemment. Un autre objet de l'invention est une poussette qui, notamment par le positionnement de l'armature offre une large gamme de possibilités d'usage.The present invention aims to conserve and develop the advantages of the folding stroller while obtaining, thanks to the constructive methods implemented, a much more compactness than previously. Another object of the invention is a stroller which, in particular by the positioning of the frame, offers a wide range of possible uses.
A cet effet, l 'invention concerne une structure repliable du type précité notamment caractérisée : - en ce que les montants comportent des organes de contrevente ent constitués de deux entretoises articulées entre elles sensiblement en leur milieu en formant un X repliable, chaque entretoise étant reliée par une liaison articulée en son sommet à l 'un des montants et à sa base à une extrémité arrière du longeron situé du côté opposé audit montant et,To this end, the invention relates to a collapsible structure of the aforementioned type, in particular characterized: by a link articulated at its top to one of the uprights and at its base at a rear end of the beam located on the side opposite to said upright and,
- en ce que chaque montant est monté pivotant pour se replier vers la partie avant de son longeron support opposé à l 'extrémité porteuse de l 'articulation de la base d ' urïe entretoise, les entretoises en X étant ainsi aptes à accompagner le mouvement de repli angulaire de chaque montant amené en pivotement contre son longeron support, la traction ainsi exercée sur le sommet des entretoises étant apte à provoquer la fermeture du X, de sorte que le repli angulaire des montants s'accompagne d'un rapprochement entre eux d'une part desdits montants et d'autre part des longerons.- in that each upright is pivotally mounted so as to fold towards the front part of its support spar opposite the bearing end of the articulation of the urea base spacer, the X-shaped spacers thus being able to accompany the movement of angular fold of each upright pivoted against its support beam, the traction thus exerted on the top of the struts being capable of causing the closure of the X, so that the angular fold of the uprights is accompanied by a bringing together of them one part of said uprights and the other side members.
D'autres caractéristiques et avantages de l 'invention ressortiront de la description qui suit et qui est donnée en rapport avec des formes de réalisation préférentielle présentées à titre d'exemples non limitatifs. La figure 1 représente une première forme de réalisation d'une structure repliable selon l 'invention du type à quatre roues.Other characteristics and advantages of the invention will emerge from the description which follows and which is given in relation to preferred embodiments presented by way of nonlimiting examples. Figure 1 shows a first embodiment of a folding structure according to the invention of the four-wheel type.
La figure 2 représente une variante de réalisation d'une structure repliable selon l 'invention du type à trois roues.Figure 2 shows an alternative embodiment of a folding structure according to the invention of the three-wheel type.
La figure 3 montre une vue schématique de la structure repliable selon l'invention dans sa position d'extension ou déployée.Figure 3 shows a schematic view of the folding structure according to the invention in its extended or deployed position.
La figure 4 montre une vue schématique de la structure repliable de la figure 3 dans sa position en cours de repli.Figure 4 shows a schematic view of the foldable structure of Figure 3 in its position during folding.
La figure 5 représente une vue en perspective éclatée des éléments composant l 'articulation des bras latéraux supports du siège.FIG. 5 represents an exploded perspective view of the elements making up the articulation of the lateral support arms of the seat.
Selon la figure 1, on voit que la structure comporte un châssis inférieur constitué des deux longerons symétriques et 1 atéraux 1 et 1 ' .According to Figure 1, we see that the structure comprises a lower chassis consisting of two symmetrical and 1 side rails 1 and 1 '.
Les longerons sont porteurs des moyens de roulement constitués, à l 'arrière, des roues porteuses 2 et 2' et, â l 'avant, des trains de roues 3 et 3' montées sur pivot autodirectionnel de type connu en soi.The longitudinal members are carriers of the rolling means consisting, at the rear, of the supporting wheels 2 and 2 'and, at the front, of the wheel assemblies 3 and 3' mounted on a self-steering pivot of a type known per se.
Les deux longerons 1 et 1 ' sont reliés entre eux par les entretoises 4, 4* articulées entre elles pour former un X repliable. L'extrémité arrière des entretoises 4, 4' est articulée sur un des longerons tandis que leur extrémité avant est articulée sur l 'avant du longeron opposé par l 'intermédiai e d'un organe de guidage tel une coulisse ou une biellette 5, 5' .The two side members 1 and 1 ′ are connected to each other by the spacers 4, 4 * hinged together to form a collapsible X. The rear end of the spacers 4, 4 ′ is articulated on one of the side members while their front end is articulated on the front of the opposite side member by means of a guide member such as a slide or a link 5, 5 '.
Les articulations de ces entretoises 4, 4' entre elles et sur les longerons se font autour d'axes parallèles entre eux et verticaux . L'ensemble des entretoises 4 et 4' et des organes de guidage 5, 5' associés constituent les organes d'accouplement des longerons 1 et 1 ' et permettent le maintien des longerons dans leur position écartée (figure 1) mais également leur rapprochement l 'un de l 'autre pour assurer la mise en position compactée de l 'ensemble (figure 3).The articulations of these spacers 4, 4 ′ between themselves and on the side members are made around axes which are parallel to each other and vertical. All of the spacers 4 and 4 ′ and the associated guide members 5, 5 ′ constitute the coupling members of the side members 1 and 1 ′ and allow the longitudinal members to be kept in their separated position (FIG. 1) but also their approximation l 'one of the other to ensure the compacted position of the assembly (Figure 3).
La structure repliable comporte encore les deux montants latéraux 6 et 6' aptes à recevoir des organes souples (tels que poche ou hamac) support des objets ou sujets transportés et reposant chacun sur un des longerons. Chaque montant est à sa base associé au longeron correspondant 1 et l' par une articulation 9, 9' d'axe transversal et située au milieu de ce longeron.The folding structure also includes the two lateral uprights 6 and 6 'capable of receiving flexible members (such as a pocket or hammock) supporting objects or subjects transported and each resting on one of the side members. Each upright is at its base associated with the corresponding spar 1 and the by a hinge 9, 9 'of transverse axis and located in the middle of this spar.
Ainsi l'ensemble du montant 6 et 6' est apte par pivotement selon l 'articulation 9, 9' à être basculé soit en position repliée où il est rabattu vers l 'avant des longerons ainsi qu'onThus the whole of the upright 6 and 6 'is adapted by pivoting along the articulation 9, 9' to be tilted either in the folded position where it is folded forward of the side members as
Te voit à la lumière de la figure 4, soit en position active où il est légèrement incliné vers l'arrière des longerons.See you in the light of Figure 4, either in the active position where it is tilted slightly towards the rear of the side members.
Chacun des deux montants est constitué de deux éléments dont un élément inférieur 7, 7' et un élément supérieur 8, 8' articulés entre eux autour d'un axe d'une chape 10 associée à l'un des éléments.Each of the two uprights consists of two elements including a lower element 7, 7 'and an upper element 8, 8' hinged together around an axis of a yoke 10 associated with one of the elements.
Aussi, chacun des deux montants 6, 6' a-t-il ses éléments susceptibles d'être repliés l'un sur l 'autre ou d'être ramenés dans Te prolongement l 'un de l'autre.Also, each of the two uprights 6, 6 'has its elements capable of being folded over one another or of being brought back in prolongation of one another.
La chape 10 que l'un des éléments comporte à cet effet, a ses patte-s orientées de manière que l'élément supérieur 8, 8* se replie vers l'arrière des éléments inférieurs 7, 7'.The yoke 10 that one of the elements has for this purpose, has its tabs oriented so that the upper element 8, 8 * folds back from the lower elements 7, 7 '.
De préférence, T 'ëTë ent inférieur 7, 7' a une longueur équivalente à la distance entre son articulation 9, 9' sur les longerons 1, 1 * et l'extrémité avant de ces longerons, tandis que l'élément supérieur 8, 8' a une longueur sensiblement équivalente à celle des longerons 1, 1 ' et de ce fait en position repliée, les éléments inférieurs 7, 7' étant rabattus vers l 'avant et les éléments supérieurs 8, 8* ve rs l 'arrière, les montants ont un encombrement équivalent à celui du châssis.Preferably, the lower ent 7, 7 has a length equivalent to the distance between its articulation 9, 9 ′ on the longitudinal members 1, 1 * and the front end of these longitudinal members, while the upper element 8, 8 ′ has a length substantially equivalent to that of the side rails 1, 1 ′ and therefore in the folded position, the lower elements 7, 7 ′ being folded forward and the upper elements 8, 8 * ve rs rear, the uprights have a footprint equivalent to that of the chassis.
L'immobilisation de l'ensemble, dans une position selon laquelle les deux éléments supérieurs 8, 8* et inférieurs 7, 7* sont sensiblement colinéaires et dans le prolongement T'un de ' î'autre, est assurée par tout organe de blocage de type connu et par exemple constitué d'un verrou pivotant porté par un élément 8, 8' et susceptible de venir par basculement s'engager derrière un organe complémentaire de l 'autre élément 7, 7*.The immobilization of the assembly, in a position in which the two upper elements 8, 8 * and lower 7, 7 * are substantially collinear and in the extension T'un of 'î'autre, is ensured by any blocking member of known type and for example consisting of a pivoting lock carried by an element 8, 8 'and capable of coming by tilting to engage behind a member complementary to the other element 7, 7 *.
Le châssis horizontal inférieur constitué par les longerons 1 et 1 ' forme avec au moins les éléments inférieurs 7, 7* des montants inclinés 6 et 6' , en vue de profil, les deux côtés d'un triangle. L'homogénéité et la triangulation de l 'ensemble sont obtenues par des éléments de contreventement arrière formés par deux entretoises 15, 15' articulées entre elles sensiblement en leur milieu autour d'un axe 16 pour former un X repliable. Les entretoises 15 et 15' sont chacune, d'une part, à leur extrémité située au sommet du contreventement, articulée dans une chape 17, elle-même articulée sur un montant 6, 6', et d'autre part à leur extrémité inférieure articulée dans une chape (non représentée) elle-même articulée sur la partie arrière du longeron 1, 1 ' situé du côté opposé au montant 1, l' auquel est associée l'autre extrémité de la même entretoise 15, 15'.The lower horizontal frame formed by the side members 1 and 1 'forms with at least the lower elements 7, 7 * inclined uprights 6 and 6', in profile view, the two sides of a triangle. The homogeneity and the triangulation of the assembly are obtained by rear bracing elements formed by two spacers 15, 15 'articulated together substantially in their middle around an axis 16 to form a foldable X. The spacers 15 and 15 'are each, on the one hand, at their end situated at the top of the bracing, articulated in a yoke 17, itself articulated on an upright 6, 6', and on the other hand at their lower end articulated in a yoke (not shown) itself articulated on the rear part of the spar 1, 1 'located on the side opposite the upright 1, l' with which is associated the other end of the same spacer 15, 15 '.
Les articulations des entretoises 15, 15' dans les chapes 17 se font autour d'axes parallèles à l'axe central 16, tandis que les chapes s'articulent sur les montants 6, 6* ou les longerons 1, l' autour d'axes horizontaux et orthogonaux aux précédents.The articulations of the spacers 15, 15 'in the yokes 17 are made around axes parallel to the central axis 16, while the yokes are articulated on the uprights 6, 6 * or the side members 1, the around axes horizontal and orthogonal to the previous ones.
Les deux entretoises en X 15, 15' sont ainsi aptes à accompagner le mouvement de repli angulaire de chaque montant amené en pivotement vers l'avant de sorte que la traction ainsi exercée sur le sommet des entretoises provoque la fermeture du X et que le repli du montant s'accompagne ainsi d'un rapprochement entre les longerons d'une part et les montants d'autre part.The two X-shaped spacers 15, 15 ′ are thus able to accompany the angular folding movement of each upright pivoted forward so that the traction thus exerted on the top of the spacers causes the closing of the X and that the folding the amount is thus accompanied by a reconciliation between the side members on the one hand and the amounts on the other hand.
Avantageusement les chapes 17 des extrémités supérieures des entretoises 15, 15' sont associées aux montants au niveau de leur élément supérieur, mais sensiblement vers la base de ceux-ci. Du fait de 1 * articul ation entre les éléments 7, 7* et 8, 8' de montants 6, 6' entre eux, lors du repliage de son ossature, en vue du profil, les longerons 1, l', le contreventement 15, 15' et les éléments de montant 6, 6' réalisent un quadrilatère dëformable dont en outre le contreventement réalise un côté de longueur variable selon l'angle des entretoises qui le forment.Advantageously, the yokes 17 of the upper ends of the spacers 15, 15 ′ are associated with the uprights at their upper element, but substantially towards the base of these. Due to 1 * articulation between the elements 7, 7 * and 8, 8 'of uprights 6, 6' between them, during the folding of its framework, in view of the profile, the side members 1, the, the bracing 15 , 15 'and the upright elements 6, 6' form a deformable quadrilateral, the bracing of which also produces a side of variable length according to the angle of the spacers which form it.
Pour rigidifier l'ensemble en position déployée et lors de la manoeuvre commander la déformation du contreventement, l'ossature est complétée par des poinçons (non représentés) qui, en s'y articulant, relient chacun l'arrière d'un des longerons à la base de l 'élément supérieur 8, 8' du montant 6, 6' s'articulant sur le même longeron 1, 1*. L'ossature comprend en outre un compas de blocage inférieur formé de deux éléments 18 et 18', articulés entre eux autour d'un axe 19 à l 'une de leurs extrémités et aux extrémités arrière des longerons par leur autre extrémité afin que leur mise en 5 extension maximale, selon un angle de 180°, assure le blocage de la structure dans sa position active déployée.To stiffen the assembly in the deployed position and during maneuver control the deformation of the bracing, the frame is completed by punches (not shown) which, by being articulated, each connect the rear of one of the side members to the base of the upper element 8, 8 ′ of the upright 6, 6 ′ hinging on the same spar 1, 1 *. The frame further comprises a lower locking compass formed by two elements 18 and 18 ', hinged together around an axis 19 at one of their ends and at the rear ends of the side members by their other end so that their positioning in 5 maximum extension, at an angle of 180 °, ensures the blocking of the structure in its active deployed position.
La partie supérieure des éléments 8 et 8' composant le montant 6 et 6' comporte évidemment des moyens qui permettent la préhension et la manoeuvre de l 'ensemble, tels par exemple une 1O poignée de canne 20, 20' de type connue mais qui par rapport à l 'axe des montants est tournée vers l 'arrière pour, en position repliée venir se placer derrière les roues arrières.The upper part of the elements 8 and 8 'making up the upright 6 and 6' obviously includes means which allow the gripping and the maneuvering of the assembly, such as for example a 1O rod handle 20, 20 'of known type but which by relative to the axis of the uprights is turned towards the rear so, in the folded position, come to stand behind the rear wheels.
Enfin les éléments supérieurs 8 et 8' sont de préférence le support d'éléments d'armature pour assurer le maintien desFinally, the upper elements 8 and 8 ′ are preferably the support for reinforcing elements to ensure the maintenance of the
15 organes souples tels que poches, hamacs (non représentés sur les dessins mais figurés en pointillés) qui constituent le support récepteur ou d'appui de l 'enfant transporté.15 flexible organs such as pockets, hammocks (not shown in the drawings but shown in dotted lines) which constitute the receiving or supporting support for the transported child.
A cet effet, à chaque élément supérieur du montant est associée indépendamment l 'une de l 'autre, une armature latéraleFor this purpose, each upper element of the upright is associated independently of one another, a lateral reinforcement
20 formée d'une paire de bras 21 et 22 et symétriquement 21 ' et 22'.20 formed of a pair of arms 21 and 22 and symmetrically 21 'and 22'.
Les bras 21, 21 ' constituent le support du fessier tandis que les bras 22, 22' situés vers l'arrière constituent le support du dossier.The arms 21, 21 'constitute the support of the gluteus while the arms 22, 22' situated towards the rear constitute the support of the backrest.
Dans chaque armature latérale indépendante le bras avant 21 25 et le bras arrière 22 sont séparément réglables en position.In each independent lateral frame, the front arm 21 and the rear arm 22 are separately adjustable in position.
En effet (figure 5) chaque bras 21, 22 ou 21' , 22' porte à son extrémité mune oreille 24, 25 distincte par laquelle il est monté pivotant autour d'un axe 26 traversant l'orifice centralIn fact (FIG. 5) each arm 21, 22 or 21 ′, 22 ′ carries at its end a separate ear 24, 25 by which it is pivotally mounted around an axis 26 passing through the central orifice
23' d'un support formant console 23 en forme d'oreille elle-même23 'of a console support 23 in the form of an ear itself
3.0 portée par le montant 8 correspondant.3.0 carried by the corresponding amount 8.
L'ensemble est bloqué en position par le bouton 27 tel un ëcrou de serrage d'une tige filetée 26 d'un boulon réalisant 1 ' axe.The assembly is locked in position by the button 27 such as a nut for tightening a threaded rod 26 of a bolt carrying out the axis.
Les faces des oreilles 23, 24, 25 disposées en regard etThe faces of the ears 23, 24, 25 arranged opposite and
35 venant en appui l 'une contre l 'autre sont pourvues de crantages radiaux permettant une immobilisation mutuelle des éléments dans la position angulaire choisie, grâce au serrage obtenu par le bouton 27 sur 1 ' axe 26. On voit en outre que les oreilles de pivotement angulaire et de maintien 24 et 25 des bras sont, à l'extrémité des bras 21 ' et35 coming to bear against one another are provided with radial notches allowing mutual immobilization of the elements in the angular position chosen, thanks to the tightening obtained by the button 27 on the axis 26. It can also be seen that the angular pivoting and holding ears 24 and 25 of the arms are, at the end of the arms 21 'and
22', légèrement déportées sur le côté et vers l'extérieur de sorte que dans leur position d'extension les deux bras 21 ' et 22' viennent en butée par leur face externe transversale.22 ', slightly offset to the side and outwards so that in their extended position the two arms 21' and 22 'come into abutment by their transverse external face.
Ainsi les deux bras peuvent définir entre eux des valeurs angulaires allant jusqu'à 180° maximum, et aucun mouvement au delà de cette valeur angulaire ne peut être constaté.Thus the two arms can define angular values between them up to 180 ° maximum, and no movement beyond this angular value can be observed.
Cette disposition constitue une sécurité qui empêche un basculement parasite ou un positionnement erroné de la part de l 'utilisateur et tel que l 'enfant ne serait plus en appui correct sur son support et risquerait de tomber.This provision constitutes a safety which prevents a parasitic tilting or an erroneous positioning on the part of the user and such that the child would no longer be in correct support on his support and would risk falling.
La structure repliable présente l 'avantage d'une grande souplesse d'adaptation à des usages multiples. Notamment elle permet d'assurer la multiplicité des positionnements de l'enfant.The folding structure has the advantage of great flexibility of adaptation to multiple uses. In particular, it ensures the multiplicity of positioning of the child.
On comprend qu'ainsi il est aisé de positionner l 'enfant soit couché, l 'ensemble constituant alors un lit, soit en position légèrement inclinée ou en position assise avec des angles variables tant pour le support du fessier que pour le dossier.It is understood that thus it is easy to position the child either lying down, the assembly then constituting a bed, either in a slightly inclined position or in a sitting position with variable angles both for the support of the buttocks and for the backrest.
Ceci permet de placer l 'enfant face au sens de la marche ou inversement face à la personne qui manoeuvre la poussette.This allows the child to be placed facing the direction of travel or vice versa facing the person who operates the stroller.
Le fonctionnement cinétique de l 'ensemble peut être compris à l 'aide de l 'examen des figures 3 et 4.The kinetic functioning of the assembly can be understood by examining Figures 3 and 4.
La figure 3 représente la poussette à quatre roues de la figure 1 dans sa position déployée tandis que la figure 4 représente cette même poussette au cours de son mouvement de repl i . Le repli de l 'ensemble débute par le dégagement du compas formé des deux éléments 18, 18', par relèvement selon la flèche FI de l 'axe d'articulation centrale 19.Figure 3 shows the four-wheeled stroller of Figure 1 in its deployed position while Figure 4 shows the same stroller during its movement of repl i. The folding of the assembly begins with the release of the compass formed by the two elements 18, 18 ′, by raising along the arrow FI of the central articulation axis 19.
Ce mouvement provoque déjà le rapproche et des deux longerons selon les flèches F2 et F3. Préalablement les moyens 21, 21 ' support d'éléments d'armature sont ramenés contre le montant correspondant. L'élément supérieur 8, 8' du montant peut alors être débloqué par dégagement du moyen de verrouillage et les deux éléments supérieur et inférieur composant le montant peuvent basculer angul airement et ainsi "casser" le montant. Ce mouvement s'effectue en appuyant sur les poignées des cannes vers le bas selon le mouvement des flèches F6, F6' de la figure 4.This movement is already bringing the two rails closer together according to the arrows F2 and F3. Prior to this, the means 21, 21 'supporting the reinforcing elements are brought back against the corresponding amount. The upper element 8, 8 'of the upright can then be released by disengaging the locking means and the two upper and lower elements making up the upright can tilt angularly and thus "break" the upright. This movement is carried out by pressing the handles of the rods downwards according to the movement of the arrows F6, F6 'in FIG. 4.
Dans ce mouvement de poussée des poignées vers le bas, les éléments haut du montant forment alors, depuis leur articulation sur les éléments bas, un 1 évier • appuyant sur le sommet des entretoises 15 et 15', tendant ainsi à les repousser vers l 'avant et avec eux le sommet des éléments inférieurs 7 et 7' des montants pivotant alors autour de leurs axes inférieurs 9 et 9' sur les longerons, ce mouvement suivant les flèches F7 et F7' de la fi gure 4.In this pushing movement of the handles downwards, the top elements of the upright then form, from their articulation on the bottom elements, a 1 sink • pressing on the top of the spacers 15 and 15 ', thus tending to push them back towards the before and with them the top of the lower elements 7 and 7 ′ of the uprights then pivoting about their lower axes 9 and 9 ′ on the side members, this movement according to the arrows F7 and F7 ′ of FIG. 4.
Dans ce mouvement de basculement vers l 'avant, indépendamment de l 'appui sur les entretoises, les extrémités supérieures des éléments 7 et 7' exercent sur elles une traction en leur partie supérieure, ce qui provoque le mouvement naturel de fermeture du X sur lui-même et ce faisant le rapprochement des deux montants associés au sommet du X et des deux longerons associés à sa base.In this tilting movement towards the front, independently of the support on the spacers, the upper ends of the elements 7 and 7 'exert on them a traction in their upper part, which causes the natural closing movement of the X on it -Even and in doing so bringing the two uprights associated with the top of the X and the two side members associated with its base.
L'ensemble aboutit ainsi à une position compactée par laquelle tous les éléments linéaires sont rassemblés en botte les uns contre les autres.The assembly thus results in a compacted position by which all the linear elements are gathered in bundles against each other.
L'équilibre structurel des éléments dans le cadre de la présente invention permet d'éviter des protubérances ou l'existence de parties débordantes qui limiteraient l 'avantage de compacité et de réduction de volume ainsi obtenus. Avantageusement, chaque roue arrière constituant une roue porteuse sera montée sur un système de suspension indépendant de tout type connu.The structural balance of the elements within the framework of the present invention makes it possible to avoid protuberances or the existence of protruding parts which would limit the advantage of compactness and reduction in volume thus obtained. Advantageously, each rear wheel constituting a carrier wheel will be mounted on an independent suspension system of any known type.
La figure 2 représente une variante de réalisation qui illustre encore les possibilités multiples d'adaptation du système selon l 'invention.FIG. 2 represents an alternative embodiment which further illustrates the multiple possibilities of adaptation of the system according to the invention.
Dans cet exemple, les deux longerons 41, 41 ' sont articulés en 42, 42' sur un noeud avant 43 situé en position médiane et qui supporte le pivot autodirectionnel 44 d'un train de roues jumelées 45. Les deux montants 46, 46' sont montés de la même façon que précédemment sur les longerons inférieurs.In this example, the two longitudinal members 41, 41 ′ are articulated at 42, 42 ′ on a front node 43 situated in the middle position and which supports the self-steering pivot 44 of a set of twin wheels 45. The two uprights 46, 46 'are mounted in the same way as above on the lower beams.
Les éléments inférieurs 47, 47' des montants sont articulés selon tous moyens appropriés sur le longeron correspondant avec un léger déport vers l 'extérieur pour rattraper le mouvement convergent des deux longerons vers le noeud avant 43.The lower elements 47, 47 ′ of the uprights are articulated by any appropriate means on the corresponding spar with a slight offset towards the outside to make up for the converging movement of the two spars towards the front node 43.
Les moyens d'accouplement des deux longerons 41 et 41' sont dans ce cas constitués simplement du noeud central avant 43 sur lequel les deux longerons sont articulés et d'autre part du compas arrière formé des deux éléments 48, 48' articulés entre eux et par leurs extrémités sur le socle 49 solidaire de l 'extrémité arrière du longeron et qui supportent également l 'articulation des entretoises de contreventement 50, 50' formant entre elles un X assurant la triangulation de la structure dans sa position déployée. The coupling means of the two beams 41 and 41 'in this case consist simply of the front central node 43 on which the two beams are articulated and on the other hand the rear compass formed of the two elements 48, 48' articulated between them and by their ends on the base 49 integral with the rear end of the beam and which also support the articulation of the bracing struts 50, 50 'forming between them an X ensuring the triangulation of the structure in its deployed position.
