Definitions

  • the present patent application for utility model 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 wall of the box and ends with a handle located immediately under the border of the wall.
  • 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.
  • collapsible - not fixed - walls does not allow to use return levers applied on the outside of the edges and permanently attached to the actuation levers of the legs located under the box.
  • the upper border of the appendix is attached to the base of the shutter.
  • the appendix and the shutter automatically disengage when the transversal sides of the box collapse and automatically engage when the transversal sides are placed back in vertical position.
  • 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).
  • transversal sides are of collapsible type, being hinged only on their upper side, while the longitudinal sides are of folding type, being hinged both on the upper and the lower side and provided with central hinge.
  • 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, as shown in Fig. 8.
  • 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 (7c), which goes through the notch (4a) and slightly protrudes outside 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 head (7c).
  • each lever (7) features an appendix consisting in a rectangular wing (7e) that protrudes upwards, on the outside of the transversal wall (3) of the box (1) and ends with an beak-like upper border (7g).
  • Each transversal wall of the box externally features a sliding shutter (10), whose lower side (10a) features a pair of external shelves (10b) capable of exactly engaging with a corresponding pair of notches (7h) located on the two sides of the wing (7e), as shown in Fig. 5.
  • the upper side (10c) of the shutter (10) features an external handle (10d) located , immediately under the border of the transversal wall (3) of the box (1).
  • the upper side (10c) of the shutter (10) also features a stop tooth (10e) capable of engaging in a suitable housing (3a) located on the transversal wall (3) of the box (1), as shown in Fig. 7.
  • the box (1) has an upper border (11) made up of a monolithic perimeter frame on which the transversal walls are hinged with pins (11a), while the two longitudinal walls of folding type are hinged to the border (11) by means of pins (12a) and to the bottom (2) of the box by means of pins (12b).
  • the bottom (2) of the box (1) features a pair of slots (2c) intersected by the wing (7e) of the actuation levers (7), while on the transversal walls the upper border (11) of the box (1) features a pair of slots (11b) perfectly aligned with the slots (2c) of the bottom (2).
  • Fig. 4 also shows how each shutter (10) is disengaged from the wing (7e) when the shutter (10) lies horizontally, together with the transversal wall, above the bottom (2) of the box.
  • the walls (3) of the box (1) can be placed in vertical position, as usual, to open the box, as shown in Figs. 1 and 2.
  • each shutter (10) automatically engages within the corresponding pair of notches (7h) located on the two sides of the wing (7e), thus connecting the wing (7e) with the shutter (10).
  • the user can reach and grab the handle (10d) of the shutters (10) with his fingertips, in order to pull the shutter upwards until the tooth (10e) engages with the housing (3a).
