Definitions

  • This invention consists of a folding trolley whose structure allows this to fold by one or both of its halves collapsing, at the same time as enabling proper securing in both the folded and unfolded positions.
  • folding trolleys working by collapsing systems applicable to rectangular surfaces, in which an upper surface and lower surface are joined by stays set in each of their vertices.
  • the means for securing these in the unfolded position is by gravity and pressure between the different articulation items, and in the folded position, only by the pressure existing between said items.
  • the structure of said trolleys means that the support surface has to be rectangular, or roughly rectangular, without any surfaces with pronounced curves having a firm support base which allows these to be used.
  • GB 1 453 515 A consists on a folding trolley consisting of a fixed frame structure and upper and lower surfaces 15 able to collapse in respect of an axis located on the plane formed by the fixed structure or very close to this, wherein the fixed structure sustains hinging means for hinged structures 36 in turn bearing moving legs, said hinged structures for supporting the moving legs being the base for supporting said collapsible surfaces in the unfolded position.
  • the structures are articulated on both vertical edges of the fixed structure, and the surfaces have rectangular shape.
  • US 1963594 refers to a foldable base to support a surface formed by two structures articulated in a vertical axis passing through the center of each of said structures.
  • This invention covers an auxiliary trolley folding by collapsing to allow surfaces of any shape to be used, with securing means for each of the items and allowing auxiliary items to be used such as a protection bar to stop bottles sliding out, or auxiliary support surfaces.
  • Figure 1 represents a perspective view of the folding trolley of the invention which, as an example, has been given a round shape (in the unfolded position).
  • Figure 2 shows a perspective view of the central structure of the folding trolley, supporting fixed legs.
  • Figure 3 shows a perspective view of the folding structure, supporting moving legs.
  • Figure 4 shows a plan view of the trolley covered by the invention.
  • Figure 5 shows a perspective view of the surfaces folding down by collapsing, as well as the stays or struts which join the upper and lower surfaces.
  • 2 and 3 respectively represent lower and upper crosspieces, which make the frame structure solid, at the same time as said crosspieces sustain other articulation items.
  • 4 are folding legs, 5a and 5b being the joining tubes or pieces between the moving legs 4 and the crosspieces of the frame 2 and 3, 6a and 6b being hinge bolts or pins slightly displaced from the crosspiece, whose free ends are opposite each other, 7 a and 7 b respectively showing upper and lower surfaces which form the support surface of the trolley.
  • 8 is a joining stay between said upper and lower surfaces
  • 9 a and 9 b representing supports for surfaces 7 a and 7 b and the hinging of these for folding down
  • 10 representing a central support for surfaces 7a and 7b.
  • 11 are side supports for surface 7a located at the top end of the moving legs 4
  • 12 supports for surface 7b located over the joining tube or part between the folding legs 4 and the crosspiece of the frame structure
  • 13 being recesses made in the lower surfaces 7b for allowing their location perpendicular to legs 4, 14a and 14b respectively showing articulations existing between each upper surface 7a and its corresponding lower one 7b.
  • 15 represents the central frame.
  • 16 shows the upper part of the frame which must match the collapsed semi-surface.
  • 17 is a protection bar for stopping bottles or other recipients sliding out, articulated in respect of structure 15 by means of hinge pins 18 in the form of bolts, which are located over holes or cavities designed for this purpose.
  • 19 shows a ridge or rib for securing the rod in its folded position over a recess 20 designed in the leg 1 of the structure 15 or, in the unfolded mode, by the leg itself 1.
  • 21 shows a support ridge for a possible tray or accessory surface, which could be a hole for housing a shaft or pin.
  • central frame structure 15 holding two fixed legs 1, joined together by two crosspieces, one above 3 and one below 2, defining an arch at the top essentially coinciding in shape with the upper surface 7 a when folded down.
  • Crosspieces 2 and 3 of said frame structure have, set out in respect of their centre and their longitudinal axis on a horizontal plane, hinge pins 6 for holding a structure formed of moving legs 4 and elements 5 a and 5 b for joining said legs 4 to the hinge pins 6.
  • a spring 22 or elastic item between the crosspieces 2 of the structure 15 and the joining elements 5b there is a spring 22 or elastic item so that its maximum extension is between the folded position and the unfolded position, so that the tendency in each of the cases will be to maintain the respective positions.
  • the unfolding of the moving legs 4 is limited by the support of the end 23 of each of the joining parts 5 a and 5 b over the corresponding crosspiece 2 and 3.
  • 24 shows a possible embodiment in which, depending on the shape of the bar 17, at least one similarly hinged surface is formed.
  • the position of said legs is situated on a line perpendicular to the centre of the line which defines the base of the central frame 15.
  • the collapsing of surfaces 7 a and 7 b is through the collapsing axis located roughly on the plane of the central structure 15.
  • the upper surface 7a has a ridge fitted with a hinge pin which, by means of a coupling rod 8 between both surfaces 7a and 7b, links up with a hinge pin located in the lower surface 7b.
  • the rod 8 crosses the lower surface 7b along a slot made in this for the purpose.
  • leg 4 prevents the surface from unfolding, also holding rod 8 for joining the top and bottom surfaces.
  • a rod 17 which takes the form of the contour over which it folds by means of a pin 18. Also, in a zone close to the ends of said rod 17 there is a ridge 19 which allows securing in the collapsed position, on the plane of structure 15, over a recess or hole 20 made in this, and in the open position on the contour of the fixed leg 1 itself.
  • support ridges 21 which could be holes for housing shafts or pins in which to insert a part, over the frame and over the moving legs for possibly locating further surfaces or semi-surfaces on these.
  • the rod 17 can constitute the frame or limit of a surface which would be bounded by the closing line 24, represented as a dotted line, also hinged.
  • This invention is for industrial application in making folding trolleys.
  • This invention consists of a folding trolley whose structure allows this to fold by one or both of its halves collapsing, at the same time as enabling proper securing in both the folded and unfolded positions.
