Definitions

  • the invention relates to a collapsible transport box, which consists of a floor and four articulated walls connected to this floor, which are provided with coupling elements for connecting together adjacent walls in the folded position, the articulated connections between at least two opposing walls and the floor by a Pin-groove connection is formed, which allows vertical and horizontal movement of these walls over a distance determined by the dimensions of the grooves.
  • This prior art corresponds to the preamble of claim 1 and is known from GB.A.1547179.
  • transport boxes take up minimal space when folded, which is advantageous when storing and transporting empty boxes.
  • vertical is understood to mean essentially vertical on the floor and horizontal essentially parallel to this floor, regardless of the position of the floor in relation to the horizontal plane.
  • FR-A 2 272 907 a collapsible transport box is known, in which two walls arranged opposite one another are provided with elongated grooves, which cooperate with pegs attached to the floor, and the coupling elements between adjacent walls made of interacting L-shaped grooves and hammer-head-shaped cams consist.
  • connection of adjacent walls is carried out by introducing these cams into the grooves of the other wall pair by moving one pair of walls horizontally and then lowering the first pair of walls so that the cams move in the vertical part of the L-shaped grooves.
  • the decoupling is done by first pulling up the first pair of walls and then pushing them outwards, after which the walls can be folded down.
  • the pivot pins are attached at different heights above the floor (FIG. 4) or the grooves of the pins - L-shaped groove connection (Fig. 5).
  • a disadvantage of the known box is that the connection between the walls in the usable state of the box is not locked in the vertical direction. As a result, the walls connected to the floor by the pin-groove connection can move upward with respect to the adjacent walls if the box is firmly packed on the first-mentioned walls when being lifted up.
  • Another disadvantage is that the complicated construction of the coupling elements makes it difficult to produce the walls of the box by injection molding a thermoplastic.
  • the invention proposes a simple construction in which the connection between the walls in the usable state of the box is locked in all directions, and which is exceptionally well suited for production by injection molding a thermoplastic.
  • each pin-groove connection has a convex curvature, as seen from the inside of the box, the distance from the floor at the outermost end of the groove being greater than at the end facing the center of the box.
  • the coupling elements of a wall consist of vertical cams located in the upper area of this wall and the coupling elements of an adjacent wall consist of shell-shaped or quiver-shaped elements located in the upper area of this wall, so that when moving up with a pin-groove connection provided wall, the cams of one wall can be inserted into the shell-shaped or quiver-shaped elements of the adjacent wall.
  • the walls provided with the pin-groove connection are now in their highest position when using the transport box, so that the box can be lifted up on these walls without the risk that the connection between adjacent walls is unlocked.
  • the grooves of the spigot-groove connection are preferably made in a raised edge part of the floor and can have different shapes, e.g. arcuate, sloping, kinked, etc., all shapes have in common that the distance to the bottom at the extreme end of the groove is greater than the end facing the center of the box.
  • the unintentional unlocking of the walls can be prevented by a push against the walls provided with the pin-groove connection.
  • This can also be achieved in that the upstanding edge is provided with thresholds, via which the walls provided with the pin-groove connection must be pressed outwards during movement.
  • the walls provided with the mortise and tenon connection on the underside Edge strips are provided, which engage in joints in the raised edge of the floor. This construction can optionally be carried out as a snap connection.
  • the coupling elements of the walls provided with the pin-groove connection are preferably encompassed from above by the coupling elements of the adjacent walls.
  • the coupling or uncoupling of adjacent walls takes place automatically when the walls provided with the pin-groove connection are moved in the transverse direction and thereby move upwards or downwards.
  • the coupling elements can e.g. consist of interacting cams and bowl-shaped or quiver-shaped elements.
  • the interconnected walls can then not be moved in the lateral direction in relation to one another in the area of the coupling elements.
  • Such a design of the coupling elements does not pose any difficulties when the walls are produced by injection molding a thermoplastic.
  • the floor is provided with an all-round raised edge 4.
  • Grooves 5 are provided in this edge, in which there are pins 6 attached to the lower edge of the side walls 2.
  • the grooves consist of an outer, horizontal part 5 'and an inner part 5 "which is inclined towards the floor.
  • the height of the edge parts 4' in which the grooves are located is somewhat larger than the height of the edge at other locations.
  • the pins 6 can be formed in one piece with the walls 2 in the production of the walls 2.
  • the side walls 3 are connected to the bottom edge 4 by fixed joints 7. These can be both pin joints and so-called film joints made of polypropylene.
  • the side walls 2 lie directly on the floor.
  • the pins 6 are located on the lowest point of the sloping part 5 "of the grooves 5, so that the walls 2 are between the upstanding edges 4.
  • the joints 7 are mounted on the edge, so that the side walls 3 are folded down Position on the side walls 2.
  • the height of the walls and the dimensions of the floor are selected in the illustrated embodiment so that walls placed opposite one another do not overlap in the folded-down position, but it is also possible to increase the dimensions of the floor and walls choose that the side walls 3 and possibly also the side walls 2 overlap in pairs in the folded-down position.
  • the upper edge of the walls 3 is provided at the ends with shell-shaped coupling elements 8 which are open on the underside.
  • the box is brought into a usable condition in that first the walls 3 are folded up and then the walls 2.
  • the articulated connection between the walls 3 and the upper edge 4 is designed so that these walls cannot pivot outwards beyond the vertical position .
  • the folded-up walls 2 are then pressed outwards.
  • the pins 6 move over the falling part 5 "to the higher part 5 'of the grooves 5.
  • the walls 2 are moved upwards, whereby cam-shaped coupling elements 9 at the ends of the upper edge of these walls engage in the shell-shaped coupling elements 8 of the walls
  • the placement of the walls 2 can be accomplished or supported in that the walls 2 are pulled up with the aid of handles 10 mounted in these walls.
  • the cams 9 are located in recesses 11 which are located at the ends of the upper edge of the walls 2 in this edge As a result, they do not protrude above the upper edge of the transport box - just like the shell-shaped coupling elements 8, which are placed over the cams 9, as shown in FIG.
  • the walls 2 are provided on the underside with an outwardly facing edge strip 12 which engages in a joint 13 of the bottom edge 4 when the folded-up walls 2 are pressed outwards. This reduces the risk of these walls being unintentionally unlocked by an impact on the lower edge.
  • the edge strip and the joint can optionally be designed as a snap connection. Furthermore, the unintentional unlocking can be countered by the fact that the horizontal part 5 'of the grooves is provided at the end with a recess for fixing the pins 6 in the usable state of the box, or that the edge 4 is partially provided with sleepers at the top, about which the Walls 2 must be pressed outwards during the movement.
  • the transport box according to the invention is preferably injection molded from a thermoplastic, such as polyethylene, polypropylene, polystyrene, etc., produced.
  • the transport box according to the invention is very well suited for use as a shopping box when transporting shop goods.
