Description

Technical area

The present invention relates to containers according to the preamble of claim 1, in particular to transport containers made of plastic, which have stacking stirrups.

State of the art

Container with stacking bracket are known, for example DE 1 721 167 U . EP 0 584 745 A1 . EP 0 669 259 A1 and EP 1 323 637 A1 , Containers according to these documents all have conical, so widening to the open container top side walls to be nestable in identical or compatible container, and therefore need to be stackable on each identical container stackable, which pivots on the respective expanded container opening can be. When two such nestable containers are stacked on each other according to the cited references, the upper container is displaced relative to the lower container by positive engagement between the lower container stacking brackets and the upper container bottom by means of specific deformations of the stacking brackets or depressions and / or projections prevented at the stacking brackets and / or at the bottom.

EP 2 548 809 A1 describes a collapsible container with stacking brackets, said ribs are also designed for a positive fit designed ribs on the stacking brackets, which can cooperate with corresponding recesses in the bottom of a container stacked on such a container of identical construction with stacking brackets.

The problem with containers with stacking ironing according to previous designs is that shifting a stacked on such a container identical container or more generally also stacked on such a container other object is prevented or made more difficult only by means of positive locking, what but this container with the On them objects to be stacked must be matched exactly and thus the selection of items that can be stacked on such containers immovable or difficult to move, is very limited.

Disclosure of the invention

Object of the present invention is therefore to provide a container with at least one stacking bracket on which a larger selection of items can be stacked immovable or difficult to move. If non-compatible containers or transport layers are stacked on top of the container, they run the risk of slipping or even slipping on the stacking bar or container.

This object is solved by features of claim 1. Advantageous developments are the subject of the dependent claims.

A container according to the invention has a bottom and a bottom upwardly extending conversion. In particular, the bottom has a substantially rectangular shape and the conversion consists of four substantially rectangular side walls. The side walls may be rigidly connected to the ground or formed integrally with increased stability requirements, but may also be hingedly connected to the ground to be able to save space in a non-loaded state. For this purpose, the side walls can also be formed foldable. At the container upper side, the four side walls form a container opening located above the bottom. At the wall, in particular at the upper edge of the wall, at least one movable stacking bracket is mounted so that it releases the container opening in a first position and is in a second position above the container opening or extends transversely through the container opening, in the second position So container opening so divides, limited or reduced, that on the container according to the invention objects, in particular other types of containers or pallets, can be stacked when the stacking bracket is in the second position.

Characteristic of a container according to the invention is that at least partially an anti-slip coating is provided on the stacking bracket. In this context, the term "coating" is generally to be understood as a layer or area on or at a surface and is not intended to be limiting to a specific manufacturing process. Thus, the coating can be produced for example by coating, sticking, brushing or shrinking. The anti-slip function of the anti-slip coating is accomplished primarily by its surface. It is therefore also conceivable that the anti-slip coating itself consists of several layers or subregions. The material of the surface of the anti-slip lining differs from the material of the underlying and / or anti-slip lining structure of the stacking bracket. Furthermore, the coefficient of friction of the surface of the anti-slip lining is higher than the coefficient of friction of the structure of the stacking bridge situated underneath and / or on the anti-slip lining. In this case, the term "friction coefficient" as a static friction coefficient, as a kinematic friction coefficient or in summary for the same time Both, static and kinematic, friction coefficients are interpreted.

A first advantage of the present invention is that by virtue of the fact that projections necessary to effect positive engagement are at least partially or partially absent, the compatibility of the container of the invention with objects, in particular other types of containers or pallets, which are fixed or non-displaceable on the container difficult to be stacked, is greatly improved. The selection of possible objects that can be stacked immovably or difficult to be stacked on the container according to the invention is thus considerably increased. In particular, objects with a smooth bottom surface, without projections or depressions on or in the outer surface of the floor, can be stacked on a container according to the invention so that a displacement or slippage of the object is difficult or impossible.

Because the anti-slip coating on the stacking bracket, in the art also called balearm or Bailarm, and thus is located on a moving part of the container, it is possible to arrange the anti-slip coating so that it is oriented in a position of the stacking bracket so that it has its anti-slip function can ensure and that it is oriented in a different position of the stacking bracket so that it is protected against accidental wear or tear. For example, the anti-slip coating can be arranged so that it is directed upward in the first position of the stacking bracket and that it is received in the second position of the stacking bracket in which the container opening is released, in a receptacle on one of the side walls of the container.

Due to the fact that no or less positive locking means are provided in a stacking bracket according to the invention, less material than in the production of a comparable stacking bracket of the same extent is necessary for the preparation of such a stacking bracket and are the manufacturing tolerances greater, since the required form fit for a compatibility of the interlocking means can be completely or partially disregarded with the corresponding counterparts. The production cost of a stacking clip according to the invention can thus be lower.

The anti-slip coating may be made of rubber, silicone, thermoplastic elastomers (TPE), polyethylene (eg LDPE) or other suitable material with a relatively high surface friction coefficient higher than that of the stacking bracket, which may be made of plastic in particular, but also of metal can exist.

According to a first advantageous embodiment of the container according to the invention, the anti-slip coating is realized such that the elasticity of the anti-slip coating is higher than the supporting structure of the stacking bracket. Carrying structure here refers to all parts of the stacking bracket, which ensure the structural integrity of the stacking bracket in an external load.

Due to the higher elasticity of the anti-slip lining, when it is loaded by an object mounted on the anti-slip lining, it yields in the areas where the article rests on the anti-slip lining, which in turn results in that the areas of the anti-slip lining which are not loaded by the article are not pressed, and thus serve as additional acting form-fitting elements for fixing the object.

A further advantage of the increased compliance of the anti-slip coating is that the article stacked on the container according to the invention is spring-supported relative to the container when this composition of container and article is transported, whereby impacts acting either on the container or on the article, only be transmitted to the other body in a reduced manner and the negative consequences of such shocks are limited.

Depending on the objects for which an inventive container should be designed as a base in a stacking, it may also be advantageous, the displacement of such objects relative to the container not in all directions only by means of frictional engagement, but in at least one direction by means of positive locking means accomplish.

Namely, if it is clear in advance that only a certain range of objects on a container according to the invention should be stackable, one can interpret the interlocking means so that shifts in directions in which an object is most likely moved by positive locking, and that shifts in the directions in which displacements are expected to be less likely to be prevented by friction. Also, the positive locking means can be interpreted as a kind of security elements, which only come into play when a stacked on a container according to the invention object has been moved by a defined maximum amount. Below this maximum value, a shift is prevented or made more difficult by frictional engagement and only after reaching the maximum displacement are the interlocking means effective. In this embodiment, therefore, the advantages of the positive connection are partially retained and simultaneously added the advantages of frictional engagement of a flat and thus compatible with different geometries effective area. The positive locking means are realized in particular in the form of projections, preferably parallelepiped or prismatic projections.

Since the surface of the anti-slip lining may possibly lose all or part of its anti-slip function due to frequent loading or wear, according to another embodiment the anti-slip lining or the anti-slip lining portions of the stacking bracket are interchangeably attached to the stacking bracket or to the remaining portions of the bracket.

This interchangeability made possible reduces the costs incurred in repairing the anti-slip coating costs. Also, a change in the friction coefficient of the anti-slip lining is easier to achieve. Since the coefficient of friction depends on the combination of the materials rubbed against one another, it is easy to adapt the anti-slip coating to the expected materials of the objects to be supported by the dismountability of the anti-slip coating. The disassembly can be accomplished for example by means of screw, adhesive, clip or click connections.

It is also advantageous if the stacking bracket made of plastic and the anti-slip coating is accomplished by an in-mold anti-slip rubber insert.

With this configuration, fabrication of the entire stacking bracket is possible so that the production of the supporting structure of the stacking bracket and the application of an anti-slip coating on the stacking bracket can be done in one step, since the anti-slip coating can be simultaneously back-poured during casting of the stacking bracket.

If it is to be expected that objects are to be stacked on the container according to the invention, in each case in comparison with the container to a great extent, it is advantageous if the sections of the stacking bracket provided with the anti-slip coating are arranged such that they are oriented upwards when the stacking bar is in the first position. In this case, the first layer is then defined not only by the fact that the stacking handle only releases the container opening, but more specifically that the stacking bracket is at least partly also above the upper edge of the conversion in the first position, thus the anti-slip coating is located at an exposed point above the top Upper edge of the conversion is located.

If, however, it is to be expected that objects are to be stacked on the container according to the invention, each with a smaller extent compared to the container, it is advantageous if the sections of the stacking bracket provided with the anti-slip coating are arranged such that they are oriented upwards, if the stacking bracket is in the second position. In particular, the second layer of the stacking bracket then also characterized in that the stacking bracket is above the upper edge of the side walls and rests on it.

Embodiments in which the portions of the stacking bracket provided with the anti-slip coating are arranged or have such an extent that they are partially oriented both upwards when the stacking bracket is in the first position, and partly oriented upwards when the stacking bar is in the second layer, of course, in view of the compatibility of the container according to the invention over objects of different dimensions may be particularly advantageous. The anti-slip coating is preferably applied only to a portion of the stacking bracket, but may also extend all around and / or over the entire length of the stacking bracket. For example, it can also be attached in the form of a shrink tube.

According to one embodiment, the walling extends substantially vertically upwards from the bottom. This is particularly advantageous if the space-saving transport of empty container according to the invention was accomplished by means of hinged and / or foldable side walls, since then the loading space of a container is maximum when the side walls are in the unfolded state.

But it may also be advantageous if the conversion widens in the direction of the container opening. The thus achieved nestability of containers according to the invention is another way to transport them in an empty state to save space.

In order for the container according to the invention in particular standardized Europoolpaletten, also called Euro pallets, immovable or difficult to be slidably stacked, it is advantageous if the container has two stacking brackets, each with two provided with a non-slip coating sections, said four sections arranged relative to each other are that they lie at the corners of an imaginary rectangle, with the long sides of the rectangle between 900 mm and 1300 mm and the short sides of the rectangle between 500 mm and 1000 mm long.

The anti-slip lining sections can be adapted to the bearing surfaces of the support feet or support skids of a Europool pallet.

The stacking bracket may have a plurality of mutually spaced, in particular evenly spaced anti-slip lining sections.

Detailed Description of the Preferred Embodiment

1 shows a container 1 according to a preferred embodiment of the invention in a perspective view. At the container 1 it is in particular a large capacity container made of plastic. It has a substantially rectangular bottom 2 on whose edges there is a transformation 3 extends substantially vertically upwards. The transformation 3 includes two opposite longitudinal side walls 3a and two transverse side walls opposite each other 3b , where the side walls 3a and 3b each also substantially rectangular in shape. The transformation 3 encloses one above the ground 2 lying substantially rectangular container opening 4 ,

At the corners of the floor 2 each extends a Behältereckfuß 2a , in the middle of each longitudinal edge of the ground 2 each extends a container longitudinal side foot 2 B and in the middle of each transverse edge of the ground 2 each extends a Behälterquerseitenfuß 2c downward. Is the container standing 1 on a flat surface, the container is stored 1 on your feet 2a . 2 B and 2c , which ensures that the forks of a truck are retractable between the feet and that the truck uses the tines to move the container 1 can lift from below.

The long side walls 3a each consist of at least two parts. Every part of a long side wall 3a is at one end over longitudinal side wall joints 3c at the respectively adjacent vertical edge of the container 1 with the respective adjacent transverse side wall 3b pivotally connected and at the other end with the other part of the longitudinal side wall 3a over sidewall closures 3d releasably rigidly connected. Be the sidewall closures 3d on both sides of the container 1 solved, the corresponding parts of the longitudinal side walls 3a in the interior of the container 1 folded and placed in a position in which the on a transverse side wall 3b attached parts of the two longitudinal side walls 3a essentially parallel to the respective transverse side wall 3b extend, and then the two transverse side walls 3b over lateral sidewall joints 3e at the respective lower edges of the transverse side walls 3b also in the interior of the container 1 folded and placed in a position in which the transverse side walls 3b and the respective attached parts of the longitudinal side walls 3a essentially parallel to the ground 2 of the container 1 extend.

If you leave the container side feet 2 B , the sidewall closures 3d and the lateral joints 3e but the bin is out of sight 1 both in the longitudinal direction and in the transverse direction substantially symmetrical.

To save as much material and weight, are part of the transformation 3 spared.

Furthermore, the container 1 each transverse side wall 3b a substantially U-shaped stacking bracket 5 with two longitudinal arms 5a a crossbeam 5b , two bearing pins, two transverse thrust locks 5d and two protrusions 5e on. The crossbeam 5b of each stacking bracket 5 is substantially prismatic and always extends in the mounted state parallel to the upper edges of the transverse side walls 3b from one longitudinal side of the container 1 to the other long side. From the two ends of the cross member 5b from two extend to each other and to the longitudinal side walls 3a parallel and equal length substantially cuboidal longitudinal arms 5a (see also 2 ). At the of the respective cross member 5b opposite ends of the longitudinal arms 5a one of each of the two stacking stirrups 5 is one to the cross beams 5b parallel and to the interior of the container 1 pointing bearing pin as part of a strap bearing 5c provided (not to be seen in the figures). The bearing pin of each longitudinal arm 5a of each stacking bracket 5 acts in each case with an outside of the wall 3 container on the longitudinal side of the corresponding transverse side wall 3b attached, upright aligned slot together and forms together with this slot one of the two bracket bearings 5c a stacking bracket 5 , Of the Bearing pin is preferably integral with the stacking bracket 5 molded, but could also be formed as a separate component that can be attached to the stacking bracket or connectable to this.

Is an inventive stacking bracket 5 in a first position (not shown in the figures), the respective bearing pins are at the lower ends of the corresponding slots, is a respective longitudinal arm 5a at the edges of a container longitudinal outer recess in the corresponding transverse side wall 3b and is the respective cross member 5b on the top edge of the container 1 in the immediate vicinity of the corresponding transverse side wall 3b on.

Is one of the two stacking bars 5 in a second position (see 1 to 5 ), the respective bearing pins are at the upper ends of the corresponding slots, is a respective longitudinal arm 5a partially at the edges of a container longitudinal outer recess in the corresponding transverse side wall 3b and partially at the edges of a container longitudinal outer recess in the corresponding longitudinal side wall 3a and is the respective cross member 3b on the top edge of the container 1 above the container opening 4 on.

It should be noted that in terms of the mobility of a stacking bracket 5 Configurations are also conceivable in which an inventive stacking bracket 5 does not need to be rotationally and translationally moved to be brought from the first position to the second position, but with the same functionality is designed only pivotable or only displaceable.

The cross section of the cross member 5 is formed so that at least one upwardly directed flat outer surface of the cross member 5b parallel to the top of the wall 3 extends, both when the stacking bracket 5 located in the first position, as well as when the stacking bar 5 located in the second location. Embodiments are also conceivable in which an upwardly directed plane outer surface of the transverse support is only in one of the two layers 5b parallel to the top of the wall 3 extends.

For mounting a stacking bracket 5 become the two longitudinal arms 5a spread, the bearing pins to the corresponding, on opposite longitudinal sides of the container 1 near a transverse sidewall 3b lying long holes and is the spread of the longitudinal arms 5a finally reduced so that the bearing pins in the corresponding longitudinal holes from the outside of the container 1 intervene.

So that unintentional slipping out of the bearing pins from the slots by a load on the stacking bracket 5 is prevented in the cross member direction, are on the side of the cross member 5b that points down when the stacking bar 5 located in the second position, jumbo backups 5d provided in the form of projections, which is a displacement of the stacking bracket 5 in the direction of the crossbeam 5b by positive cooperation with the longitudinal side walls 3a , In particular by positive cooperation with the inner sides of the longitudinal side walls 3a , prevent.

At the side of the cross member 5b , which points upwards when the stacking bracket 5 located in the second position are at the ends of the cross member 5b page limits 5e provided in the form of protrusions, the lateral slipping in the direction of the cross member 5b one on the stacking hanger 5 Prevent stored object by positive locking.

On the side of the respective cross member 5b , which points upwards when the corresponding stacking bracket 5 located in the second position are each outside, near the ends of the cross member 5b or if page boundaries 5e are provided, near the side boundaries 5e , Anti-slip pads 6 appropriate. These protrude upwards more than the remaining areas of the cross member 5b , Only if page boundaries 5 are provided, they project beyond the anti-slip coverings 6 up. The anti-slip coverings 6 have a substantially rectangular shape, with the extension of the short sides of each of the anti-slip pads 6 in the transverse direction of the cross member 5b essentially over the entire width of the cross member 5b extends and the longer side of each anti-slip decking 6 each between one sixth and one fifth of the total length of the cross member 5b is long.

The container 1 and the stacking bars 5 are made of plastic, preferably by means of an injection molding process. In the production of a stacking bracket 5 become the rubber anti-slip coverings 6 inserted so in the injection mold, that essentially only the backs of the anti-slip pads 6 be back-poured from the melt and thus the anti-slip coatings 6 during solidification of the melt with the stacking bracket 5 be joined by adhesion during the normal injection molding process.

Both static and kinematic coefficients of friction of the preferred anti-slip coatings 6 are larger than the corresponding friction coefficients of the stacking bracket 5 , The elasticity of the anti-slip coverings 6 is also greater than the elasticity of the stacking bracket 5 ,

The dimensions of the container 1 are generally chosen so that the container 1 Can be easily integrated into existing transport and logistics systems. This means in particular that the longitudinal dimension of the container 1 essentially with the longitudinal dimension of one after the European standard EN 13698-1 standardized Europool range 7 matches (see 3 to 5 ). The area of the container opening 4 essentially corresponds to the extent of a pallet surface 7a the Europool palette 7 so the latter as a cover for the container 1 can be used. The total of four anti-slip surfaces 6 of the container 1 are arranged so that the over pallet cradles 7b and pallet long side feet 7c at the Europoolpalette 7 mounted pallet long side skids 7e on the anti-slip surfaces 6 rest when the Europoolpalette 7 on the container 1 is stacked. The total of four page boundaries 5e are like that on the stacking bars 5 formed that the pallet longitudinal side skids 7e near the side boundaries 5e are located when the Europoolpalette 7 on the container 1 is stacked (see 5 ). The arrangement of the container feet 2a , the tank side feet feet 2 B and the container lateral feet 2c essentially corresponds to the arrangement of the pallet cradles 7b , the pallet long side feet 7c and of pallet cross-feet 7d a Europool palette 7 , which ensures that the container 1 can be lifted from four sides each with the same material handling equipment configuration as a Europool pallet 7 ,

Is a Europoolpalette 7 on the container 1 Stacked, will shift the Europoolpalette 7 in the longitudinal direction of the container 1 using anti-slip flooring 6 frictionally prevented or impeded, is a shift in the Europoolpalette 7 in the transverse direction of the container 1 initially with the help of anti-slip flooring 6 frictionally prevented or impeded and will push down the Europoolpalette 7 from the container 1 in the transverse direction of the container 1 using the page boundaries 5e prevented or impeded by positive locking. The additional backup using the page boundaries 5e is therefore straight in the transverse direction of the container 1 provided because the side openings of the container 1 stacked Europoolpalette 7 for retracting tines of an industrial truck on the lateral side of the Europool pallet 7 smaller than on the long side and thus the probability of accidental knocking the tines of the truck on the Europoolpalette 7 and a concomitant shift in the Europool range 7 when entering the tines in the transverse direction is greater than in the longitudinal direction (see 4 and 5 ).
