Definitions

  • the present patent application relates to a plastic box with collapsible walls, provided with support legs that can be folded under the bottom of the box.
  • Plastic-moulded boxes with four legs hinged on horizontal pins are already available on the market.
  • the legs can be closed in a raised position under the bottom of the box or opened in a lowered, slightly divergent position in order to lift the box off the ground.
  • the applicant is the owner of the Italian patent for utility model No. 01264112, which relates to a similar box whose legs are closed by means of a lever pivoted at one end located in central position under the bottom of the box.
  • each lateral pair of legs is attached to an actuation lever by means of a pin inserted into a suitably shaped slot of the lever, whose free end is connected to a plate that slides on the outside of one transversal edge of the box and ends with a handle located immediately under the border of the edge.
  • the vertical movement of the plates lifts the actuation levers until they touch the bottom of the box.
  • the vertical movement of the levers corresponds to the inward vertical overturn of the legs, because of the special shape of the slot in which the pin connecting each pair of legs to its actuation lever is inserted and slides.
  • the legs are closed by overcoming the opposite action of two springs that oppose the lifting of the two actuation levers.
  • the springs also ensure the forced lowering of the levers as soon as the stop tooth is ejected from its housing, thus automatically opening the legs.
  • the purpose of the present invention is to use folding legs with actuation levers on boxes provided with collapsible walls, that is walls that can be collapsed towards the inside of the box until they are placed flat on the bottom.
  • collapsible - not fixed - walls does not allow to use sliding plates that can be attached to the edges in order to actuate the levers of the legs located under the box.
  • the handle is provided with a tooth that engages with a suitable notch located on the support base of the box, once the handle has been completely raised.
  • the handle is produced in a single piece with the actuation lever and features a thinner section used to attach it to the lever, which acts as an elastic hinge between the handle and the lever.
  • the user By pushing the handle towards the inside of the box, the user can flex it in order to disengage the stop tooth from the notch, thus automatically opening the legs by means of the springs loaded when the actuation levers of the legs are lifted.
  • the box (1) according to the present invention has a rectangular bottom (2).
  • Four lateral walls (3) are hinged on horizontal pins on the four sides of the bottom (2), with the possibility of collapsing them inside of the box (1) until they are placed flat on the bottom (2), provided with a support base (4).
  • a notch (4a) is located in central position on the two transversal sides of the base (4), internally delimited by an opposite pair of tabs (5) with central holes (5a), in which the pivoting pins (6a) of each pair of folding legs (6) are inserted.
  • each pair of legs (6) is an integral part of a single plastic piece shaped as a portal and formed by a top crosspiece (6b) and two lateral legs (6).
  • a deep cradle (6c) is located in the centre of the top crosspiece (6b) with the pivoting pins (6a) protruding from the opposite walls.
  • Each pair of legs (6) is moved by means of an actuation lever (7) consisting in a longitudinal plate that laterally features an opposite coaxial pair of pins (7a) with horizontal axis at one end, which are inserted into housing holes (2a) located on a parallel pair of longitudinal separators (2b) on the lower side of the bottom (2).
  • the holes (2a) are located in the proximity of the transversal symmetrical axis of the box (1).
  • a cup housing (7b) is centrally located on the actuation lever (7), which houses a pre-compressed spring (8) located between the bottom (2) and the lever (7).
  • the free end of the actuation lever (7) features a head capable of acting as handle (7c), which goes through the notch (4a) and slightly protrudes outside the base (4).
  • Two flexible teeth (7d) are provided on the two sides of the handle (7c), capable of engaging with small notches (4) located on the base (4).
  • Each actuation lever (7) is connected to its pair of legs (6) by means of a pin (9) fixed through the cradle (6c) and inserted into a slot (7e) located on the lever (7) near the handle (7c).
  • the handle (7c) is produced in a single piece with the actuation lever (7) and features a thinner section (S) used to attach it to the lever, which acts as an elastic hinge between the handle (7c) and the lever (7).
  • the base (4) instead of the notch (4a), the base (4) features a flexible tongue (40) with external button (40a), suitable for engaging into a hole located on the handle (7c), whose ending section (7e) exactly embraces the flexible tongue (40) from the outside.
  • the user needs to push the button (40a) with his fingertips to flex the flexible tongue (40) towards the inside, until the button (40a) comes out of the housing hole and the lever (7) is actuated downwards under the action of the springs (8).
  • the base (4) instead of the notch (4a), the base (4) features a flexible tongue (50) with internal tooth (50a), capable of engaging with a corresponding tooth (7f) on the ending section (7e) of the handle, which is held against the internal wall of the flexible tongue (50).
  • the user needs to push the tongue (50) towards the outside with his fingertips until the tooth (7f) no longer interferes with the tooth (50a) and the lever (7) is actuated downwards under the action of the springs (8).
  • a flexible tongue (60) with internal tooth (60a) is located under the bottom of the box, capable of engaging into a corresponding slot (7g) located on the handle (7c).
  • the user needs to flex the flexible tongue (60) towards the outside with his fingertips until the tooth (60a) comes out of the slot (7g) and the lever (7) is actuated downwards under the action of the springs (8).
  • Figs. 12 and 13 are identical to the embodiments illustrated in Figs. 9 and 10, respectively, with the only difference that in the embodiments shown in Figs. 12 and 13 the tongues (400) and (500) are rigid and not flexible, so that the lever (7) cannot be engaged or disengaged by means of the elastic deformation of the tongues (400 and 500).
  • the hinging pins (7a) of the lever (7) are housed in two elongated slots (20a) that allow the lever (7) to slide under the box as needed to actuate or eliminate the constraint between the button (400a) and the handle (7c) in the embodiment of Fig. 12, or between the tooth (500a) and the handle in the embodiment of Fig. 13.
