Abstract
Description
La présente invention concerne un chariot
pliant, plus particulièrement destiné aux travaux quotidiens -de nettoyage, de rangement et de préparation des pièces dans tous les corps de métier, notamment en hostellerie.The present invention relates to a carriage
folding, more particularly intended for daily work -cleaning, storage and preparation of parts in all trades, especially in hotels.
Dans ce dernier domaine en effet, on sait que
les interventions du personnel, nécessaires au moins une
fois par jour, impliquent le transport du matériel et des
produits d'entretien, d'une part, et des fournitures utili
sées et propres, d'autre part. Dans ces conditions, les
chariots utilisés doivent être susceptibles de transporter
des charges souvent importantes tout en restant stables
et facilement manoeuvrables, tandis qu'en outre, ils doi
vent être rangés entre les interventions en occupant le
moins de place possible.Or, les conditions d'emploi rappe
lées brièvement ci-dessus impliquent des chariots relati
vement encombrants du fait de leur obligatoire robustesse
et leur rangement nécessite des locaux particuliers parfois
éloignés des zones où ils sont appelés à être utilisés, ces
deux impératifs ne pouvant être satisfaits par les types
de chariots pliants existant à l'heure actuelle.In this last area, in fact, we know that
staff interventions, necessary at least one
times a day involve the transportation of equipment and
cleaning products, on the one hand, and supplies used
neat and clean, on the other hand. Under these conditions, the
used carts must be capable of carrying
often heavy loads while remaining stable
and easily maneuverable, while in addition they must
can be stored between interventions while occupying the
as little space as possible.
Briefly above involve carts related
bulky items due to their compulsory robustness
and their storage requires special premises sometimes
distant from the areas where they are to be used, these
two imperatives that cannot be satisfied by types
of folding trolleys existing today.
La présente invention vise à remédier aux
inconvénients ci-dessus, en fournissant un chariot pliant présentant à la fois la possibilité de supporter des charges
importantes en restant stable et manoeuvrable, ainsi que d'être plié de façon aisée afin d'occuper un volume de
rangement minimal.The present invention aims to remedy the
above drawbacks, providing a folding cart with both the ability to support loads
important while remaining stable and maneuverable, as well as being folded in an easy way in order to occupy a volume of
minimal storage.
Conformément à l'invention, le chariot pliant comporte une ossature fixe comprenant un dosseret flexible muni d'un socle à sa partie inférieure et d'un bras de
force transversal sur lequel est fixé un coffret à sa partie supérieure, parallèlement au socle, un plateau in
férieur rabattable articulé à la base du dosseret et pouvant prendre appui sur le socle, un casier supérieur articulé sur ledit bras de force et muni de ridelles destinées
à prendre appui sur le coffret, le casier comportant à son extrémité opposée à son articulation deux montants articulés sur lesdites ridelles et dont la longueur est telle que, en position d'utilisation du chariot, les pieds des montants exercent un effort sur le plateau inférieur tandis que leur articulation amène les ridelles à exercer un effort sur le coffret.According to the invention, the folding cart has a fixed frame comprising a flexible backsplash provided with a base at its lower part and an arm
transverse force on which is fixed a box at its upper part, parallel to the base, a plate in
lower hinged articulated at the base of the backsplash and being able to rest on the base, an upper locker articulated on said force arm and provided with side panels intended
to bear on the box, the rack comprising at its end opposite to its articulation two uprights articulated on said drop sides and the length of which is such that, in the position of use of the carriage, the legs of the uprights exert a force on the lower plate while their articulation causes the drop sides to exert a force on the cabinet.
Selon cet agencement, les éléments constitutifs coopèrent de façon que, en position d'utilisation, le dosseret soit soumis à deux efforts à ses extrémités, tendant à le déformer vers une concavité dirigée à l'opposé du plateau et du casier. According to this arrangement, the constituent elements cooperate so that, in the position of use, the backsplash is subjected to two efforts at its ends, tending to deform it towards a concavity directed opposite the tray and the rack.

Sur ces dessins, les mêmes références désignent les mêmes éléments. In these drawings, the same references designate the same elements.
En se référant à ces dessins, l'ossature fixe est constituée par un dosseret 1 muni à sa partie inférieure d'un socle 2 et, à sa partie supérieure, d'un coffret 3 fixé sur un bras de force transversal 4 parallèle au socle 2. I1 y a lieu de noter que ce socle est fixé au dosseret 1 selon un angle A légèyement inférieur à 90 , dans un but qui sera expliqué ci-après. Referring to these drawings, the fixed frame consists of a backrest 1 provided at its lower part with a base 2 and, at its upper part, a box 3 fixed on a transverse force arm 4 parallel to the base 2. It should be noted that this base is fixed to the backsplash 1 at an angle A slightly less than 90, for a purpose which will be explained below.
Un plateau inférieur 5 est articulé sur la partie inférieure du dosseret 1, par exemple au moyen d'une charnièrebaguette 6, de façon qu'il puisse prendre appui sur le socle 2 en position d'utilisation ou être replié sur le dosseret 1 en position de rangement (voir fig. 3, 5).A lower plate 5 is articulated on the lower part of the backsplash 1, for example by means of a boot hinge 6, so that it can bear on the base 2 in the use position or be folded back on the backrest 1 in the position storage (see fig. 3, 5).
Le casier supérieur, de référence générale 7, est articulé sur le bras de force 4 au moyen d'une seconde charnière-baguette, dont seul l'axe d'articulation 8 a été représenté dans un but de clarté. Le casier 7 est muni de ridelles 9 dont une arête antérieure 10 peut prendre appui sur la face postérieure 11 du coffret 3.The upper locker, of general reference 7, is articulated on the force arm 4 by means of a second hinge-rod, of which only the articulation axis 8 has been shown for the sake of clarity. The rack 7 is provided with side panels 9, one front edge 10 of which can bear on the rear face 11 of the box 3.
A leur extrémité opposée à son articulation 8, les ridelles comportent un axe d'articulation 12 de deux montants 13 pouvant se replier le long desdites ridelles (fig. 3) ou prendre appui sur le plateau 5 (fig. 1, 7).At their end opposite to its articulation 8, the sides have a hinge pin 12 of two uprights 13 which can be folded along said sides (fig. 3) or bear on the plate 5 (fig. 1, 7).
L'ossature fixe du chariot est constituée du dosseret 1, du socle 2 et du bras de force 4 avec le coffret 3 et présente une profondeur p suffisante pour loger la dimension des organes repliés, comme représenté sur la figure 3. De manière connue en soi, le chariot est muni de roulettes orientables, à savoir, un jeu de roulettes 14 équipant la partie inférieure du socle 2 et permettant la manoeuvre à l'état plié, et un jeu de roulettes 15 à la partie inférieure du plateau 5 pour la manoeuvre et la stabilité en position d'utilisation. The fixed frame of the carriage consists of the backrest 1, the base 2 and the force arm 4 with the box 3 and has a depth p sufficient to accommodate the dimension of the folded members, as shown in FIG. 3. In a manner known in itself, the carriage is provided with swivel casters, namely, a set of rollers 14 equipping the lower part of the base 2 and allowing the operation in the folded state, and a set of rollers 15 at the lower part of the plate 5 for the maneuvering and stability in position of use.
Comme mentionné plus haut, la longueur 1 d'un montant 13 est telle que, en position d'utilisation du chariot, son pied 16 exerce un effort sur le plateau 5 de façon que celui-ci soit sensiblement parallèle au fond 17 du casier 7. Dans cette position, l'angle A étant inférieur à 900, le socle 2 transmet un premier effort de déformation À la partie inférieure du dosseret. As mentioned above, the length 1 of an upright 13 is such that, in the use position of the carriage, its foot 16 exerts a force on the plate 5 so that the latter is substantially parallel to the bottom 17 of the rack 7 In this position, the angle A being less than 900, the base 2 transmits a first deformation force to the lower part of the backsplash.
Par ailleurs, la longueur L des ridelles est telle qu'en position d'utilisation, l'arête 10 s'applique sur la face 11 du coffret, de façon que celui-ci transmette un second effort à la partie supérieure du dosseret 1, qui tend alors vers une concavité C (fig. 7), sa flexibilité permettant l'équerrage et une stabilisation efficace de l'ensemble de la structure du chariot.Furthermore, the length L of the drop sides is such that in the position of use, the edge 10 is applied to the face 11 of the box, so that the latter transmits a second force to the upper part of the backrest 1, which then tends towards a concavity C (fig. 7), its flexibility allowing squaring and effective stabilization of the entire structure of the carriage.
Pour le passage de la position d'utilisation (fig. 7) à la position de rangement (fig. 3), les opérations sont simples et rapides : on dégage vers ltexté- rieur des deux montants 13 et l'on rabat le plateau 5 contre le dosseret 1 (fig. 4) ; on rabat le casier 7 contre le plateau replié, on relève complètement les montants et on les fixe contre le coffret, par exemple au moyen de clips 17 portés par les faces latérales dudit coffret (fig. 5, 3). Pour le passage de la position pliée de rangement à la position d'utilisation, les opérations c i-dessus s'effectuent dans le sens inverse, à savoir, on relève le casier 7, on abaisse le plateau 5, on abaisse et l'on engage les montants 13 (fig. 6). For the passage from the position of use (fig. 7) to the storage position (fig. 3), the operations are simple and rapid: one releases the two uprights 13 towards the inside and the tray 5 is folded down against the backsplash 1 (fig. 4); the compartment 7 is folded against the folded plate, the uprights are completely raised and they are fixed against the cabinet, for example by means of clips 17 carried by the lateral faces of said cabinet (fig. 5, 3). For the passage from the folded storage position to the use position, the operations above are carried out in the opposite direction, namely, the rack 7 is raised, the tray 5 is lowered, it is lowered and the uprights 13 are engaged (fig. 6).
I1 est bien entendu que la présente invention n'a été décrite et représentée qu'À titre explicatif mais nullement limitatif et qu'on pourra y apporter toute modification utile, notamment dans le domaine des équivalences techniques, sans sortir de son cadre. It is understood that the present invention has only been described and shown for explanatory purposes but in no way limiting and that any useful modification may be made to it, in particular in the field of technical equivalences, without going beyond its ambit.
