Description

STACKABLE INDUSTRIAL TRANSPORT AND STORAGE BOX

DESCRIPTION

Field of the invention

The invention is situated in the field of industrial storage and transport. In particular in the field of boxes and containers used in industry for the transport and storage of products.

More specifically, the invention relates to a stackable industrial storage and transport box comprising:

- a rectangular container, consisting of four vertical walls and a base; wherein each vertical wall has an internal face and an external face, and is delimited on its external face by an external boundary plane, such that said external boundary planes of said four vertical walls form an outer boundary surface of the container having a rectangular shape; Y

- a removable cover, configured to cover said container in a position of use, which has an internal face and an external face.

This type of rectangular boxes have the advantage that they are easily stackable and can be placed next to each other optimizing the available space, which is highly advantageous both in transport and storage.

Generally, the vertical walls are straight or have elements such as reinforcing ribs on their outer face projecting to a maximum external contour corresponding to said outer boundary surface. Being rectangular, said outer boundary surface allows space optimization indicated above. In case the vertical walls are smooth surfaces, said external boundary surface corresponds to the external surface of the vertical walls.

By way of clarification, unless otherwise indicated, in the context of the invention the appellatives of "internal" or "external" will be understood relative to the box, in particular to the inside or outside of the box, respectively .

State of the art

Some types of products require transport in closed boxes. For example, in the case of products with small, powdery or liquid parts, among others. For this, removable covers for containers are known, which can be placed and removed from said containers. In the context of this document, the term "box" is used to refer to the container and lid assembly, it is convenient that said covers have a geometry that does not alter the optimization of the storage space, including stacking.

However, it is often necessary to ensure that the lid does not fall or accidentally open. In order to fasten said covers to the containers to keep them covered, the known solutions use elements such as staples, clips, or even packaging tapes.

However, known solutions have several drawbacks. First, they often modify the external geometry of the box, making it difficult to store it, either horizontally or stacked. Secondly, these fastening systems are not safe against situations such as bumps or falls, which can occur during the handling of the boxes. This last point is particularly relevant in case the boxes contain potentially dangerous products, and even for sensitive products that could be affected if they fall out of the box.

For these reasons, a solution is necessary that allows the secure attachment of the lid of a box for storage and industrial transport, which at the same time allows to optimize the space required for the storage of said boxes, including stacking.

Description of the invention

The purpose of the invention is to provide a stackable industrial storage and transport box of the type indicated at the beginning, which makes it possible to solve the aforementioned technical problems.

This purpose is achieved by means of a box of the type indicated at the beginning, characterized in that said cover is provided with at least one security closure comprising: - an actuator, operable between a closing position and an opening position or vice versa, said actuator being operable from the external face of said lid; and - two latches, arranged on the inner face of said lid in opposite directions with respect to said actuator, so that, in position of use, each of said two latches faces the internal face of one of said vertical walls, said two latches being facing two of said opposite vertical walls;

said actuator being configured to act on said two latches to move them between an extended position when said actuator is in said closing position, to a retracted position when said actuator is in said opening position, or vice versa;

wherein, in the use position, when said latches are in said extended position, they are inserted in closing holes provided in said vertical walls, without protruding from said external boundary surface of said container, while when said latches are in said position. retracted position, are removed from said closing holes.

In this way, when the latches are inserted into the closing holes, a fastening of the lid occurs. This clamping does not affect the external geometry of the box, thus optimizing the space required for the storage of the boxes, since there are no external elements that protrude. On the other hand, the closing mechanism is inside the box, on the inner side of the lid, except the accessible part of the actuator that is made from the external side, and with the latches facing the internal faces of the walls . In this way, safety is increased and the risk of accidental opening is minimized. Each safety closure comprises two latches that act in opposite directions and that are operated by the user through a single actuator. This facilitates the use while increasing safety since there are two closing points that hold the lid to the container for each safety lock, with these closing points on opposite walls.

An additional advantage of this configuration is that it is very simple to implement starting from existing containers in the market, since it only requires modifying the existing container creating the closing holes. This makes it possible to easily reuse already available containers.

On the basis of the invention defined in the main claim, preferred embodiments are provided whose characteristics are set forth in the dependent claims.

Preferably, said cover comprises, for each of said at least one safety lock, an access hole for said actuator and fastening means configured to hold said safety lock to said cover. This has the advantage that it is easy to implement starting from box covers already existing in the market, since it only requires modifying the existing cover creating an access hole for each security closure, and securing said at least one security lock to the lid. In some preferred forms, the latches are fastened by staples to the inner face of the lid. The staples and the actuator are fixed to the lid by fixing means such as rivets, screws, welding or any other means known in the art. Preferably said fixing means comprise rivets, which is an economical option as well as robust, easily adaptable to a wide variety of sizes and materials of caps.

Preferably, said lid is delimited on its external face by an external limit plane of said lid, and in which said actuator does not protrude from said external limit plane. This configuration facilitates the optimization of space needed when stacking the boxes, since the actuator does not protrude above the lid and therefore, there is less risk of it contacting the box that can be stacked on top of said lid.

Preferably, said closing holes are through. This is particularly advantageous in case the outer faces of the vertical walls are of the type comprising a flat surface from which elements such as ribs protrude. Said through holes can thus cross the flat surface, maximizing the fastening and the safety of the closure, but as long as they do not protrude beyond the ribs.

Preferably, said actuator further comprises locking means for locking the actuator when it is in said closing position. This configuration increases safety and hinders accidental openings with the case closed, particularly in cases of knocks or falls.

In advantageous embodiments, said actuator is rotary and is configured such that the passage from said closing position to said opening position or vice versa said actuator is made by a rotation of said actuator. This has two main advantages: first, it facilitates the user opening and closing maneuvers. Second, it improves safety since a circular movement is necessary for the opening of the safety lock. Since bumps or falls generally involve linear movements, this option makes it difficult to accidentally open the safety lock in those cases.

Preferably said circular movement is a rotation of between 30 ° and 90 °, which allows to open or close with a single manual rotation. A particularly advantageous option for manual operation is a 45 ° rotation.

Preferably, said latches are configured so that they are displaceable between said extended position and said retracted position or vice versa, by means of a linear movement. In this way the latches move linearly towards the inner face of the vertical wall, preferably in a direction perpendicular to said vertical wall. Since a lateral movement of the latches is not necessary, this allows the closing holes to be sized closer to the latches, which means a firmer fastening when the safety latch is closed. This in turn increases the safety and robustness of the solution, especially with regard to lateral forces. For example, in case the closing holes needed a width much greater than that of the latch itself because said latch moved laterally between the extended and retracted positions, if the box suffered a lateral impact with the closed safety latch, there would be possibility that the latch moved laterally. This could cause the latch to even come out of the closing hole or at least to move inside the box.

Preferably, said actuator is configured to act on said two latches by means of traction means, arranged between said actuator and said latches, on the internal face of said lid. Thus, the traction means transform the circular movement of the actuator into a traction that involves a displacement of the latches. In this way, the mechanism acting on the latches is hidden and protected from the outside of the case, while it is possible to operate it from the outer face of the lid.

Preferably, said traction means comprise a toothed wheel and straight serrated sections; wherein said actuator comprises a handle provided on the external face of said cover and joined together with said toothed wheel provided on the internal face of said cover, so that a rotation of said handle causes a rotation of said gear wheel; Y wherein each of said two latches presents one of said straight serrated sections, arranged tangentially to said toothed wheel and meshing with said toothed wheel, so that a rotation of said toothed wheel causes a linear displacement of said straight serrated sections, which are arranged parallel to each other and on opposite sides of said gear wheel. Thus, a circular movement of the lever of the actuator is transmitted to the sprocket and in turn to the two latches, which move linearly in opposite directions. In this way it is possible to open and close the safety lock with a single rotation of the handle. The gears assume a robust system, although other embodiments use other types of traction pull known in the art. In a preferred embodiment said handle and said gear wheel form a single piece that can rotate inside a housing that is fixed to the cover.

Preferably, each of said latches comprises:

- a first straight section, close to said actuator and comprising said straight serrated section;

- a second straight section, remote from said actuator and provided with a closing end configured to be inserted in one of said closing holes; Y

- an intermediate section joined together with said first section and said second section;

said second section being parallel to said first section and aligned with the center of said cogwheel. In a preferred embodiment, said first straight section, second straight section and intermediate section form a single piece, which maximizes the robustness. The intermediate section is preferably straight and oblique, so that the force that the actuator prints on the latches is linearly channeled to the second straight section, minimizing the lateral forces.

Preferably, said latches are fastened to said cover by said first straight section and said second straight section. This allows a more adjusted driving since they are the sections that move linearly along its shape. This adjusted driving has in turn the advantage of greater robustness, since it is less affected against lateral forces for the reasons described above.

Preferably, said actuator comprises a bayonet catch configured to lock said actuator when said actuator is in said closing position. This supposes a lock in the closing position that increases the security, being the bayonet closure particularly advantageous in case the actuator is operated by a circular movement.

Preferably, said lid is provided with more than one of said safety latches, which is especially advantageous for large boxes, in which more than two fastening points are required for the lid. A particularly advantageous option is given with lids provided with two safety locks, which supposes four fastening points and at the same time allows opening and closing maneuvers in a single step, when the user uses both hands, one in each closing security.

Unless otherwise specified, reference will be made in this document to a longitudinal direction or longitudinally disposed elements in the manner customary in the art, that is, when said direction is oriented in the same direction as the larger dimension of the box. in a horizontal plane. In a complementary manner, a transverse direction or transversely arranged elements will be referred to, when said direction is oriented in the same direction as the smaller dimension of the box in said horizontal plane, that is, the direction orthogonal to said longitudinal direction in said plane horizontal. In case all the sides of the box have the same dimensions, the choice of the longitudinal or transverse direction is arbitrary.

Preferably, said safety locks are all arranged in parallel, either transversely or longitudinally in said cover, which avoids the need for the latches to cross each other, which could mean an increase in the space required by the safety lock that it would affect the effective space available to store products inside the box. The arrangement of the closures is preferably transverse, which means bolts of shorter length, thus minimizing the necessary manufacturing material and increasing the overall resistance.

The invention also encompasses other detailed features illustrated in the detailed description of an embodiment of the invention and in the accompanying figures.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Figs. 1 and 2 show an embodiment of a stackable industrial storage and transport box 1 according to the invention. The box comprises a rectangular container 2, formed by four vertical walls 21 and a base 22. Each vertical wall 21 has an internal face 211 and an external face 212. In the section shown in Fig. 12 the example of a of the vertical walls 21 which is delimited on its external face 212 by an external boundary plane 213. The rest of the vertical walls 21 are delimited by respective external boundary planes. In the case of the example, the vertical walls 21 have a smooth outer surface on their external face 212, in which projections or ribs 214 are arranged. For the sake of clarity, only a few protrusions 214 have been marked in the figures. of example. These projections 214 project from the smooth outer surface to a maximum distance delimited by said external boundary plane 213. Said outer boundary planes 213 of said four vertical walls 21 form an outer boundary surface of the container 2 having a rectangular shape. Thus, this external boundary surface delimits the contour occupied by box 1.

The box 1 also comprises a removable lid 3, configured to cover said container 2 in a position of use. Said lid 3 has an internal face 301 and an external face 302. Figs. 1 and 2 show the complete box 1, while Fig. 3 and 4 show the lid 3 in isolation.

The cover 3 is provided with at least one security closure 4. In the example of FIGS. 1 to 4, the box comprises two of said security latches 4. Other embodiments comprise a single security closure 4. other embodiments, especially for very large and / or elongated boxes, comprise more than two security locks 4.

The safety lock 4 comprises an actuator 41 and two latches 42. The actuator 41 is operable between a closing position and an opening position or vice versa. In addition, said actuator 41 is operable from the outer face 302 of said lid 3. Fig. 12 shows that, similarly to the vertical walls 21, the lid 3 of the example is also delimited in

one

its external face 302 by an external boundary plane 303. Thus, for the example of FIGS. 1 to 4, the actuator 41 does not protrude from said external boundary plane 303.

As seen in Fig. 4, the two latches 42 are disposed on the inner face 301 of the lid 3 in opposite directions with respect to said actuator 41, so that, in the position of use, each of said two latches 42 is facing the inner face 301 of one of said vertical walls 21. In the example, the latches 42 are faced perpendicular to the vertical walls 21 and the safety latches 4 are arranged in the transverse direction. As can be seen in the figures, the two latches 42 face two of said opposite vertical walls 21 of the container 2.

For its part, the actuator 41 is configured to act on said two latches 42 to move them between an extended position when said actuator 41 is in the closed position, to a retracted position when said actuator 41 is in the open position, or vice versa . In this way, when the actuator 41 is in the closed position and the two latches 42 are in the extended position, the safety lock 4 is closed, whereas when the actuator 41 is in the open position and the two latches 42 are in position retracted, security lock 4 remains open.

In any case, when the lid 3 is placed in the use position, when said latches 42 are in extended position, they are inserted in closing holes 23 provided in said vertical walls 21, without protruding from said external boundary surface of said container 2, while when said latches 42 are in retracted position, they are removed from said closing holes 23. In the example of the figures, the closing holes 23 are through.

In the figures it can be seen how the actuator 41 is rotatable and is configured so that the passage from the closing position to the opening position or vice versa of the actuator 41 is carried out by a rotation of said actuator 41, in particular by a rotation of 45 °, although other examples show other degrees of rotation. As can be seen in FIGS. 7 and 8, the safety lock 4 has a pulling means between the actuator 41 and the latches 42, arranged on the inner face 301 of the cover 3. In particular, said pulling means comprise a toothed wheel 412 and straight serrated sections 421. Thus, the actuator 41 of the example comprises a moving part 413 which can be rotated within a housing 414. The moving part 413 is formed by a handle 411 provided on the outer face 302 of the lid 3 and joined together with said toothed wheel 412 provided on the inner face 301 of said cover 3. In this way, a rotation of said handle 411 causes a rotation of said sprocket 412. On the other hand, each of said two latches 42 has one of said straight serrated sections 421, arranged tangentially to said sprocket 412 and meshing with said sprocket 412. Thus, a rotation of the sprocket 412 as a consequence of a rotation of the lever 411 causes a linear displacement of said straight serrated sections 421, which are arranged parallel to each other and on opposite sides of said sprocket 412, so that the movement is transmitted of the actuator 41 to the latches 42 causing them to move in opposite directions with respect to said actuator 41.

In Figs. 5 to 8 the detail of the latches 42 according to the embodiment can be seen. In particular, each latch 42 comprises three sections joined together forming a single body:

- a first straight section 422, close to the actuator 41 and comprising said straight toothed section 421;

- a second straight section 423, remote from the actuator 41 and provided with a closing end 425 configured to be inserted in one of said closing holes 23; and - an intermediate section 424 joined to the first and second sections 422, 423 forming a single body.

The first and second sections 422, 423 are parallel to each other, and the second section 423 is aligned with the center of the gear wheel 412 of the actuator 41. The intermediate section 424 is arranged obliquely to join the first section 422 with the second section 423. The particular shapes of the sections 422, 423 and 424 and the latches 42 obey the requirements of weight and resistance imposed by the dimensions and materials of the box, among other considerations. Thus, for these examples, the latches 42 have a flat upper surface and reinforcing ribs on the underside. Also the second section 423 has a vertical widening in the area close to the closing end 425 which allows to increase the resistance and at the same time to arrange the closing end 425 in a lower position than the rest of the latch 42. At the same time, the end 425 is arranged in step with respect to the rest of the latch. This allows a more secure closure since the respective closure hole 23 can be arranged with a greater thickness of vertical wall 21 above said closing hole 23, which increases the strength and minimizes the possibility of breakage in that part of the body. vertical wall 21. At the same time, since the vertical widening is only at the end, the volume required for the safety lock is minimized.

The latches 42 are attached to the cover 3 by said first straight section 422 and said second section 423 straight. In particular, in the second section 423, the fastening is carried out by means of a clip 426 which is connected to the internal face 301 of the cover 3, while in the first section 422 the fastening is made by the casing 414 of the actuator 41, given that the first section 422 of the latches is inserted in said housing 414. The cover 3 of the example has access holes for the actuator 41, so that the handle 411 of each actuator 41 is accessible from the external face 302 of the cover 3 through said access hole.

For the example of the figures, both the housing 414 and the clips 426 are fixed to the cover 3 by fixing means which, for the case of the examples, comprise rivets 31. Although the rivets are a preferred form since the ends have little protuberance on the outer face 302 of the cover 3, other examples include alternative fixing means such as screws, welds, etc.

In Figs. 9 to 11 the detail of a bayonet catch provided on the actuator 41 and configured to lock said actuator 41 when said actuator 41 is in the closed position is shown. Fig. 9 and 10 show the case of closure position, in which a projection 415 attached to the moving part 413 of the actuator 41 is blocked by a slit 416 provided in the housing 414 of the actuator 41. Springs 417 push the part movable 413 upwardly so that the projection 415 is inserted in said slot 416 with the springs 417 extended. Fig. 11 shows the case of the opening position, in which said projection 415 abuts the stop wall 418 of the housing 414, and the springs 417 are compressed. In this way, when the actuator 42 is in the closed position and a user wants to open the safety lock, it first pushes down the movable part 413 from the handle 411, thus compressing the springs 417 and pushing the projection 415 out of position. the slit 416. From the moment when the projection 415 is outside the slit 416 the user can rotate the lever 411, until said projection 415 abuts the stop wall 418. For the example, this supposes a 45 ° rotation counterclockwise. The closing operation is just the inverse to that described above, first a rotation of the handle 411 which in the case of the example is 45 ° in a clockwise direction. At that moment the projection 415 faces the groove 416, the springs push the moving part 413 upwards, thus introducing the projection 415 in the groove 416 and being blocked by it.
