Abstract

Stable stacking system of interlocking boxes of different sizes, the length of the large box (1) is twice the width of the small box, these boxes (1) being stackable and nestable, of the right rectangular parallelepiped type with a walking all around on their middle part, provided with housings (4) on the upper half of their sides and, on the lower half of these sides, with projections / supports allowing the stacking of the boxes (1) under load, one on the others, and allowing, thanks to a rotation of 180 degrees, to fit them into each other. The system is characterized in that the protrusions / supports located on the longer sides and their corresponding housings (4) of the large body (1) are arranged so as to be compatible with the projections / supports located on the longer sides. courts and their corresponding housings of petty cash.

Description

The present invention relates to a system for stacking, so as to

  interlocking, two sizes of stackable and nestable boxes of the right rectangular parallelepiped type, the length of the first box being twice the width of the

second case.

  There are stackable and nestable boxes of the right rectangular parallelepiped type with an all-around step in their middle part, comprising housings in the upper half of their sides and projections / supports on the lower half of these sides, operably arranged between them so to allow stacking of the crates in charge on each other, and to allow, thanks to a rotation of 180 degrees,

  to fit them into each other.

  An improvement of this type of crates is also known, the purpose of which is to allow the upper crate to slide and sit firmly on the lower crate even if the protrusions / supports have a reduced size, thanks to a provision of inclined planes. located on the lower part of the projections / supports which center the upper box on the lower box provided that the first is supported on the second to perform the stacking or sliding on this

last.

  There is also a second improvement of this type of boxes allowing the most resistant projection / support to be the one that supports the largest load, by means of division, into two parts of different widths, thanks to a groove or slot in the longitudinal direction, the widest and widest projection / support

  away from the corresponding end of the side.

  There is also a third improvement of this type of crates allowing them to withstand high loads when it is occasionally necessary, thanks to the addition of an optional projection / support which helps the projection / support the smallest in the effort to support the load, located at the bottom end of the crate

  adjacent to the smallest projection / support.

  These enhancements are subject to different ownership records of the request. Nevertheless, it was impossible until now to be able to stack crates of this type when the length of the largest crate is twice the width of the crate.

the smallest box.

  In order to achieve this inter-relationship, it is provided that the protrusions / supports and their corresponding recesses of the larger box, located on the longer sides, are arranged so that they are compatible with the projections / supports and their corresponding housings of the smallest box, located on the shorter sides, thus making it possible to stack, in an intermingled and stable way, two smaller boxes on a box larger than a larger box on two

smaller crates.

  If it is desired to stack a single small box on another larger without losing stability during transport, there are provided on the ends of the upper edge of the large box of the respective depressions adapted to receive the lower ends of the projections / supports of the smaller body superimposed, which avoid that it

  does not move during transport.

  If two smaller crates are stacked on a larger crate, these depressions have been designed to accommodate any protrusion / support of the crates, allowing them to be stacked without

their orientation.

  If a larger crate is stacked on two smaller crates, the latter can also receive the large crate in any orientation direction of the latter, making the lower ends of the projections / supports of the large fund are steadily supported by

  edges of the shorter sides of the petty cash.

  From this, it is deduced that during the stacking process, either manual or automatic, it is not necessary to pay attention to the orientation of small boxes when they are stacked on the large boxes since the two sides the shorter ones of the petty cash can be received by any longer side of the big box. It is also not necessary to pay attention to the orientation of the large crate when it is stacked on the small crates because the two longest sides of the crate can be received by

  any shorter side of small crates.

  In order to facilitate the understanding of the invention,

  the following description is accompanied by seven boards

  of drawings representing an embodiment cited in

as a non-limitative example.

  - Figure 1 is a top view of the large box. - Figure 2 is a top view of the petty cash. - Figure 3 is a view of a petty cash

  stacked on a larger crate.

  FIG. 4 is a view of two small boxes in the two possible directions of orientation, stacked on

a big box.

  - Figure 5 is the same view as Figure 4 but

  the large box is oriented in the opposite direction.

  FIG. 6 is a view of a large box stacked on two small boxes, each oriented in a

different meaning.

  - Figure 7 is the same view as Figure 6 but

  the large box is oriented in the opposite direction.

  Referring to the figures, there is shown a large box (1) whose projections / supports (3) and their corresponding housing (4) are arranged so that they are compatible with the projections / supports (5) and their corresponding housing (6). ) of the petty cash (2), so that it is possible to stack on load: (a) - a single small box on a large box (Figure 3), (b) - two small boxes on a large box , whatever their direction of orientation, or the direction of orientation of the large box (Figures 4 and 5), and (c) - a large box on two small boxes regardless of the direction of orientation of small boxes or the direction of orientation

  of the big box (Figures 6 and 7).

  The large box (1) has, at the ends of its upper edges, depressions (7) for receiving the lower ends of any of the projections / supports (5) of the petty cash. These depressions were also designed to prevent a petty cash from moving during transport when

  it is desired to stack a single small box on a large box (Figure 3).

Claims (2)

  1. Stable stacking system of boxes (1,2) nestable and of different sizes, the length of the large box (1) is twice the width of the petty cash (2), these boxes (1,2) being stackable and nestable, parallelepiped right rectangle type with a walk all around their middle part, provided with housings (2,4) on the upper half of their sides and, on the lower half of these sides, protrusions / supports ( 3,5) enabling the crates (1,2) to be stacked on top of one another and, thanks to a rotation of 180 degrees, to be able to fit them into each other, characterized in that the projections on the long sides and their corresponding seats (4) of the large box (1) are arranged to be compatible with the projections / supports (5) on the shorter sides and their corresponding housings (6) of the small boxes (2), thus making it possible to stack stably both two small boxes (2) on a large box (1), regardless of the direction of orientation of the small boxes (2), a large box (1) on two small boxes (2) independently of the sense of orientation of the great cashier (1).   2. System according to the preceding claim, characterized in that there are provided depressions (7) on the ends of the upper edges of the longer sides of the large box (1), adapted to receive the ends of the projections / supports ( 5) small boxes (2) superimposed, these depressions (7) being designed so that when stacking a single small box (2) on another large box (1), the petty cash (2) remains stable during the transport.
