Definitions

  • the present invention consists of a folding carriage that by its structure allows folding by folding one or its two halves, while allowing a correct fixation both in folded and unfolded position.
  • Collapsible folding trolleys are known that are applicable to rectangular shapes, in which an upper surface and a lower surface are joined by means of existing straps in each of its vertices.
  • the fixing means in the deployed position are by gravity and pressure between the different articulation pieces, and in a folded position, only because of the pressure between said parts.
  • the structure of said carriages requires that the support surface be rectangular or approximately rectangular, without surfaces with pronounced curves having a firm support base that allows its use
  • the present invention aims at a folding folding auxiliary car that allows the use of surfaces of any shape, provides fixing means for each of the elements, and allows the use of auxiliary elements such as a protector for sliding bottles or auxiliary support surfaces
  • Figure 1 represents a perspective view of the folding carriage of the invention which, by way of example, has been provided with a round shape (in an unfolded position).
  • Figure 2 shows a perspective view of a central frame of which the folding carriage, which has fixed legs, is provided.
  • Figure 3 shows a perspective view of the folding carrier structure of movable legs.
  • Figure 4 shows a plan view of the car of the invention
  • Figure 5 shows a perspective view of the collapsible folding surfaces, as well as of braces that join the upper and lower surfaces.
  • 19 indicates a rod fixing projection, in the folded position on a recess 20 provided in the leg 1 of the frame 15 or in the deployed mode, by the leg 1.
  • 21 shows a projection of support of a possible tray or accessory surface, which can be a hole for eeo pivot housing
  • a central frame 15 bearing two fixed legs 1, joined together by two crossbars, one upper 3 and one lower 2, defining an arc in its upper part essentially comfortable in shape with the top surface 7a folded down
  • the crossbars 2 and 3 of said frame have axes 6 supporting a structure formed by movable legs 4 and elements displaced with respect to its center and its longitudinal axis in a horizontal plane.
  • connection 5a and 5b of said legs 4 to the articulation axes 6
  • a spring 22 or elastic element is positioned so that the maximum extension occurs between the folded position and the deployed position, so the tendency in each case will be to maintain the respective positions
  • the deployment of the movable legs 4 is limited by the support of the former stage 23 of each of the connecting pieces 5a and 5b on the corresponding crossbar 2 and 3
  • With 24 a possible embodiment is shown in which according to the shape of the rod 17, at least one equally articulated surface is formed.
  • the position of said legs is located on a perpendicular line on the center of the line that defines the base of the central frame 15.
  • the abatement of the surfaces 7a and 7b is produced by a pivot axis located approximately in the plane of the central frame 15.
  • the upper surface 7a has a projection provided with an articulation axis that by means of a connecting rod 8 between both surfaces 7a and 7b links with an articulation shaft located on the lower surface 7b.
  • the rod 8 crosses the lower surface 7b through a groove made therein.
  • a recess 13 is provided on said surface 7b so that the leg is inserted in it, preventing its articulation while the surfaces are deployed
  • a rod 17 can be provided that takes the shape of the contour on which it is folded by means of an axis 18.
  • a projection 19 is also provided near the ends of said rod 17 which allows fixing in a collapsed position, in the plane of the frame 15, on a recess or hole 20 made therein, and in an open position on the contour of the fixed leg 1.
  • Supporting projections 21 are also provided, which could be bore holes for shafts or pivots in which to insert a piece, on the frame and on the movable legs for the possible location on these of additional surfaces or semi-surfaces.
  • the rod 17 may constitute the frame or boundary of a surface that would be delimited by the closing line 24, represented in strokes, also articulated. It is capable of industrial application in the manufacture of folding cars.

Abstract

L'invention concerne un chariot pliable présentant des surfaces des plateaux que l'on peut rabattre (7a, 7b) et comprenant un châssis (15) fixe et des structures de support de pieds mobiles (4) pliables de manière excentrique sur le châssis fixe. On prévoit des butées de dépliage et des moyens d'insertion et d'appui des plateaux sur les pieds mobiles ainsi que des accessoires tels qu'une barre de protection pour bouteilles ou autres récipients ou éléments d'appui pour des surfaces supplémentaires. Cette invention trouve une application industrielle dans la fabrication des chariots pliables.
