Definitions

  • This patent application for a utility model concerns a crate moulded in plastic with inward folding sides.
  • Moulded plastic crates are currently widely used thanks to the fact that they are light, sturdy and inexpensive.
  • This type of crate has four lateral sides which, during use, are locked reciprocally in a vertical position; when the crates are not used, the coupling of the sides is released in order to fold the same downwards and inwards.
  • These sides are hinged for this purpose to the four sides of the bottom of the crate, with respect to which they can be folded from a vertical position, when in use, to a horizontal position, when they are not used and vice versa.
  • folding of the sides must be performed in a specific order; to go from a horizontal to a vertical position it is necessary to open the longitudinal sides and then the transverse sides, and vice versa from a vertical to a horizontal position.
  • the transverse edges of the long sides are provided with two or more hooked teeth designed to house and wedge into corresponding hollowed housings - at a suitable height - on the transverse edges of the short sides.
  • hooking means makes the reciprocal locking and unlocking of the sides so difficult since in order to lock the four sides of a crate of this kind, it is necessary to move first the longitudinal and then the transverse sides to a vertical position, align the teeth of the longitudinal sides and the housings of the transverse sides precisely, and finally press to ensure that said hooking means of the four sides wedge into place.
  • the main problem when locking the sides is the difficulty in aligning the teeth of the longitudinal sides and the corresponding housings on the transverse sides quickly enough.
  • the item according to the invention is designed to eliminate the problems encountered with conventional crates when locking and releasing the sides.
  • the inventive idea provides the crates in question with a different locking mechanism of the sides, which does not require the user to personally align and couple the means which permit the stable fixing of the four crate sides.
  • said fixing means are permanently coupled, so that all the user is required to do when opening and closing the crate, is to fold the sides over.
  • the new crate in question consists generally of four folding sides hinged to the four edges of the bottom wall; here, as in the case of conventional crates, the four walls may be moved from a vertical position, inwards, to abut against the bottom wall, and vice versa from a horizontal position when the crate is not used to a vertical position when the crate is used.
  • each of the transverse edges of the short sides are provided with two projecting pins with enlarged head, made of the same material and during the same moulding phase as the transverse sides.
  • Another consequent feature of the crate according to the invention is that the internal surface of each longitudinal side is provided with two pairs of concentric curved grooves whose centre coincides with the pivoting axis of the transverse side; in other words, said grooves correspond to the same number of hooking and sliding runners for the pins made on the transverse sides.
  • each of these pairs is located at one of the ends of said longitudinal side.
  • Each groove is curved for a quarter of the circumference, starting from the hinged edge of the longitudinal wall and ending at the transverse side of the same side.
  • Said longitudinal sides are pivoted, on the bottom, to a raised edge which is an integral part of the bottom of the crate, and is characterised by a height equal to the thickness of the transverse sides, which, when turned flat against the bottom of the crate, wedge precisely into the raised edges to which the long sides are pivoted.
  • each of said edges are provided with four perfectly aligned notches with the mouth of the four curved grooves made on the internal surface of each longitudinal wall.
  • the crate In order to describe the method of locking the sides of the new crate in question, the crate is considered to be in a "compacted" position.
  • the first step is to fold the two longitudinal opposing sides from a horizontal to a vertical position.
  • the first effect of folding the transverse walls upwards is to immediately wedge the two pairs of pins projecting from the two sides of each of said transverse sides, into the mouth of the two pairs of grooves, which, as mentioned above, are perfectly aligned with the notches on the raised hinging edges of the longitudinal sides.
  • Said grooves are designed to house and guide the pins during folding of the corresponding transverse sides.
  • each runner is provided with a pair of jaws which wedge the leg of a pin, whose enlarged head remains outside the pair of jaws, turned towards the exterior of the crate.
  • the full length of the sliding runners of the pins is provided with two rims between which the leg of the pin slides, while the relevant enlarged head of the pin remains wedged outside the pair of rims.
  • Releasing the sides of the crate according to the invention is achieved simply by uncoupling the pins of the transverse sides from the jaws at the upper end of the corresponding runner.
  • the crate (1)-entirely moulded in plastic - consists of a bottom wall (2) and two opposing pairs of folding lateral sides (3 and 4).
  • Said walls are hinged to the bottom (2) of crate (1); in particular, the two longitudinal sides (3) are hinged to corresponding raised edges (2a) on the long sides of the bottom (2) of the crate (1) and characterised by a height (H) equal to the thickness (S) of the transverse sides (4).
  • Said transverse sides (4) are in turn hinged directly on the short sides of the bottom (2) of the crate (1).
  • Each of the four sides (3 and 4) is in fact provided on its bottom side with a series of notches (5) having corresponding pivoting pins (6) designed to wedge into corresponding specific jaws along the four sides of the bottom (2) of the crate (1).
  • Each of the transverse sides (4) of the crate in question (1) is characterised by two pins (7) with enlarged head (7a) for each of its lateral edges while each longitudinal side (3) is characterised in that its internal surface is provided with two pairs of concentric curved runners (8) corresponding to a quarter of the circumference and whose centre coincides with the pivoting axis of the sides (4).
  • each groove (8) positioned on the bottom side of its corresponding logitudinal side (3) overlies and is aligned perfectly to a notch (9) on the raised edge (2a) on which the longitudinal side is hinged.
  • each of said grooves (8) which is positioned on the side edge of the corresponding side (3), is provided with a pair of jaws (10) designed to wedge and fix the leg of pin (7) housed and sliding in the groove (8).
  • said pair of jaws (10) correspond to the shaped end section of an opposing pair of rims (10a) whose purpose is to reduce the space of the groove (8) so that it is equal to the diameter of the leg of pin (7), whose enlarged head (7a) has a diameter equal to the width of the groove (8) and remains wedged out of said pair of rims (10a), facing towards the exterior of the crate (1).
  • this feature permits on one hand the guided sliding of the pins (7) of the transverse sides (4) in the corresponding grooves (8) of the longitudinal sides (3) and on the other hand it prevents the accidental removal of said pins (7) from the corresponding grooves (8) and thus the uncoupling of the longitudinal sides (3) from the transverse walls (4).
